**The information in this preliminary prospectus is not complete and may be changed.

**SUBJECT TO COMPLETION, DATED FEBRUARY 13, 2023** 

**PRELIMINARY PROSPECTUS**![amci-20230213_g1.jpg](amci-20230213_g1.jpg)

**Up to 218,067,996 Shares of Common Stock** 

**4,774,276 Warrants to Purchase Common Stock** 

This prospectus relates to the issuance by us of an aggregate of up to 19,249,473 shares of our common stock, $0.0001 par value per share ("common stock"), which consists of (i) up to 4,774,276 shares of common stock that are issuable upon the exercise of private placement warrants (the "Private Placement Warrants") originally issued in a private placement to AMCI Sponsor II LLC (the "Sponsor") in connection with the initial public offering ("IPO") of AMCI Acquisition Corp. II ("AMCI") and upon the conversion of certain working capital loans of the Sponsor, at a price of $1.00 per warrant, (ii) up to 7,494,514 shares of common stock that are issuable upon the exercise of public warrants (the "Public Warrants" and, together with the Private Placement Warrants, the "warrants") originally issued in connection with the AMCI IPO as units of AMCI at a price of $10.00 per unit, with each unit consisting of one ordinary share and one-half of one warrant, (iii) up to 5,000,000 shares of common stock that are issuable upon the conversion of that certain Simple Agreement for Future Equity between BGTF LT Aggregator LP ("Brookfield") and LanzaTech NZ, Inc., dated October 3, 2022 (the "Brookfield SAFE") at the equivalent to a price of $10.00 per share, (iv) up to 300,000 shares of common stock that are issuable under a warrant held by ArcelorMittal XCarb S. à r.l. ("ArcelorMittal"), dated December 8, 2021 (the "AM Warrant") at the equivalent to a price of $10.00 per share, and (v) up to 1,680,683 shares of common stock underlying options issued to certain holders under our incentive plans (the "Options" and together with the warrants, the AM Warrant and the Brookfield SAFE, the "Convertible Securities") held by certain selling stockholders. We will receive the proceeds from the exercise of any warrants, the AM Warrant or the Options for cash.

This prospectus also relates to the offer and sale from time to time by the selling stockholders named in this prospectus or their permitted transferees (the "selling stockholders") of up to 4,774,276 Private Placement Warrants and up to 198,818,523 shares of common stock, which consists of (i) up to 18,500,000 shares of common stock issued on February 8, 2023 in a private placement pursuant to subscription agreements, dated March 8, 2022, October 18, 2022, February 1, 2023, and February 6, 2023 (each as amended, as applicable), at a price of $10.00 per share (the "PIPE Shares"), (ii) up to 4,774,276 shares of common stock that are issuable upon the exercise of the Private Placement Warrants, (iii) up to 5,000,000 shares of common stock that are issuable upon the conversion of the Brookfield SAFE, (iv) up to 300,000 shares of common stock that are issuable upon the exercise of the AM Warrant, (v) up to 2,164,839 shares of common stock held by certain selling stockholders, (vi) up to 1,680,683 shares of common stock underlying the Options held by certain selling stockholders, (vii) up to 5,916,514 shares of common stock purchased by certain selling stockholders subject to that certain forward purchase agreement by and between the Company, ACM ARRT H LLC ("ACM"), and the other parties thereto (the "Forward Purchase Agreement"), and (viii) up to 160,482,211 shares of common stock, required to be registered pursuant to that certain Registration Rights Agreement, dated February 8, 2023 (the "Registration Rights Agreement"), by and among us and certain of the selling stockholders. We will not receive any proceeds from the sale of the Private Placement Warrants or of the common stock by the selling stockholders pursuant to this prospectus.

The selling stockholders may offer, sell or distribute all or a portion of the securities hereby registered publicly or through private transactions at prevailing market prices or at negotiated prices. We are required to pay certain costs, expenses and fees in connection with the registration of these securities, including with regard to compliance with state securities or "blue sky" laws. The selling stockholders will bear all commissions and discounts, if any, attributable to their sale of Private Placement Warrants or shares of common stock. See the section titled "Plan of Distribution."

Our common stock and warrants are listed on the Nasdaq Capital Market ("Nasdaq") under the symbols "LNZA" and "LNZAW," respectively. On February 10, 2023, the last reported sales price of the common stock was $7.30 per share.

The common stock and the common stock issuable upon exercise of the resale securities noted above represent a substantial percentage of the total outstanding shares of our common stock as of the date of this prospectus. Additionally, if all of the Convertible Securities were converted, or exercised, as applicable, the selling stockholders would own 198,818,523 shares of common stock, representing approximately 92.3% of the total outstanding common stock. So long as the registration statement of which this prospectus forms a part is effective, the sales of the securities being offered in this prospectus could result in a significant decline in the public trading price of the common stock. The sales of certain such securities are subject to lock-up restrictions. Furthermore, if the market price for shares of common stock is less than the exercise price of a holder's warrant or of the AM Warrant, such holder may be less likely to exercise the warrants, the AM Warrant or the Options, as the case may be, as such holder would be selling at a loss if they sold their common stock. Subject to adjustment, the exercise price of the warrants is $11.50 per share and the exercise price of the AM Warrant is $10.00 per share. The exercise prices of the Options range from $1.07 per share to $3.15 per share. On February 10, 2023 the last reported sales price of the common stock was $7.30 per share. Additionally, if the market price for shares of common stock is less than $10.00 per share, holders of shares of common stock would be selling at a loss if they purchased the shares of common stock at $10.00 per share. Because certain selling stockholders purchased shares privately at a price below the current market price, they may have an incentive to sell shares of their common stock because they could profit despite the market price of common stock falling below $10.00 per share. While these selling stockholders may, on average, experience a positive rate of return based on the current market price, public securityholders may not experience a similar rate of return on the securities they purchased due to differences in the purchase prices and the current market price.

We are an "emerging growth company" and a "smaller reporting company" as defined under the U.S. federal securities laws. See "Prospectus Summary — Implications of Being an Emerging Growth Company and a Smaller Reporting Company." This prospectus complies with the requirements that apply to an issuer that is an emerging growth company and a smaller reporting company.

**Investing in the common stock involves risks. See "[Risk Factors](#ib82e114cd19f45afae73e7a64e42f208_1575)" beginning on page [7](#ib82e114cd19f45afae73e7a64e42f208_1575) of this prospectus to read about factors you should consider before investing in the common stock.** 

**Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or passed upon the accuracy or adequacy of this prospectus. Any representation to the contrary is a criminal offense.** 

The date of this prospectus is&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; , 2023.

**ABOUT THIS PROSPECTUS** 

This prospectus is part of a registration statement on Form S-1 that we filed with the SEC using the "shelf" registration process. This prospectus relates to the issuance by us of the shares of common stock issuable upon the exercise of any Convertible Securities. Under this shelf registration process, the selling stockholders may, from time to time, sell the securities offered by them described in this prospectus. We will not receive any proceeds from the sale by such selling stockholders of the securities offered by them described in this prospectus.

Neither we nor the selling stockholders have authorized anyone to provide you with information that is different from or in addition to the information contained in this prospectus or in any applicable prospectus supplement or in any related free writing prospectus prepared by or on behalf of us or to which we have referred you. Accordingly, neither we nor any selling stockholder takes any responsibility for, or can provide any assurance as to the reliability of, any information that others may give. Neither we nor any selling stockholder will make any offers to sell or seek any offers to buy these securities in any jurisdiction where the offer or sale is not permitted. You should assume that the information contained in this prospectus, any applicable prospectus supplement, and any related free writing prospectus is accurate only as of the respective dates of such documents, regardless of the time of delivery of the respective documents or any sale of securities offered hereby. Our business, financial condition, results of operations and prospects may have changed materially since those dates.

We may also provide a prospectus supplement or post-effective amendment to the registration statement to add information to, or update or change information contained in, this prospectus. You should read this prospectus and any applicable prospectus supplement or post-effective amendment to the registration statement together with the additional information to which we refer you in the section of this prospectus titled "Where You Can Find More Information."

On February 8, 2023 (the "Closing Date"), LanzaTech NZ, Inc. ("Legacy LanzaTech") and AMCI consummated the previously announced business combination pursuant to that certain Merger Agreement, as amended on December 7, 2022 (the "Merger Agreement"), by and among Legacy LanzaTech, AMCI and AMCI Merger Sub ("Merger Sub"), a Delaware corporation and wholly owned subsidiary of AMCI. As contemplated by the Merger Agreement, Merger Sub merged with and into Legacy LanzaTech, with Legacy LanzaTech continuing as the surviving corporation and as a wholly owned subsidiary of AMCI (the "Business Combination"). On the Closing Date, AMCI changed its name to LanzaTech Global, Inc.

Unless the context indicates otherwise, references in this prospectus to the "Company," "LanzaTech," "we," "us," "our" and similar terms refer to LanzaTech Global, Inc. (formerly known as AMCI Acquisition Corp. II) and its consolidated subsidiaries (including LanzaTech NZ, Inc.) following the Business Combination. References to "AMCI" refer to AMCI Acquisition Corp. II prior to the Business Combination and references to "Legacy LanzaTech" refer to LanzaTech NZ, Inc. prior to the Business Combination.

References to "PRC" or "China" refer to the People's Republic of China, which, solely for the purpose of this prospectus, exclude Taiwan and the special administrative regions of Hong Kong and Macau.

Notwithstanding the legal form of the Business Combination pursuant to the Merger Agreement, the Business Combination will be accounted for as a reverse recapitalization in accordance with accounting principles generally accepted in the United States of America ("US GAAP"). Under this method of accounting, AMCI will be treated as the acquired company for financial reporting purposes, whereas Legacy LanzaTech will be treated as the accounting acquirer. In accordance with this accounting method, the Business Combination will be treated as the equivalent of Legacy LanzaTech issuing stock for the net assets of AMCI, accompanied by a recapitalization. The net assets of AMCI will be stated at historical cost, with no goodwill or other intangible assets recorded, and operations prior to the Business Combination will be those of LanzaTech.

**FORWARD-LOOKING STATEMENTS** 

This prospectus contains statements that are forward-looking and as such are not historical facts. This includes, without limitation, statements regarding the financial position, business strategy and the plans and objectives of management for future operations. These statements constitute projections, forecasts and forward-looking statements, and are not guarantees of performance. Such statements can be identified by the fact that they do not relate strictly to historical or current facts. When used in this prospectus, words such as "anticipate," "believe," "continue," "could," "estimate," "expect," "intend," "may," "might," "plan," "possible," "potential," "predict," "project," "should," "strive," "would" and similar expressions may identify forward-looking statements, but the absence of these words does not mean that a statement is not forward-looking. When we discusses our strategies or plans, we are making projections, forecasts or forward-looking statements. Such statements are based on the beliefs of, as well as assumptions made by and information currently available to, LanzaTech's management.

Forward-looking statements in this prospectus may include, for example, statements about:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our anticipated growth rate and market opportunities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our ability to maintain the listing of our securities on Nasdaq;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the potential liquidity and trading of our securities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our ability to raise financing in the future;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our assessment of the competitive landscape;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our ability to comply with laws and regulations applicable to our business;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our ability to enter into, successfully maintain and manage relationships with industry partners;

**PROSPECTUS SUMMARY**

*This summary highlights selected information contained in this prospectus. This summary does not contain all the information that you should consider before investing in our warrants or common stock. You should read the entire prospectus carefully, including the "Risk Factors," "Forward-Looking Statements" and "Management's Discussion and Analysis of Financial Condition and Results of Operations" sections, and our historical financial statements and the accompanying notes included elsewhere in this prospectus.* 

**Company Overview** 

LanzaTech is a nature-based carbon refining company that transforms waste carbon into the chemical building blocks for consumer goods such as sustainable fuels, fabrics, and packaging that people use in their daily lives. Using LanzaTech's process technology, LanzaTech's partners launched the world's first commercial carbon refining plant in 2018 in China. Since then, LanzaTech's partners have launched an additional two commercial plants operating in China, one in April 2021 and the other in September 2022. LanzaTech has numerous projects in construction, under development and in the pipeline globally. LanzaTech's technology platform is designed to use a variety of waste feedstocks, from waste industrial gases to biomass residues and municipal solid waste. LanzaTech's technology platform is designed to capitalize on the demand for sustainable fuels and chemicals, which can be used in multiple sectors such as aviation, automotive, textiles, home goods, consumer goods and others, to address the growing preference among major companies for environmentally conscious products and manufacturing processes.

**Business Combination** 

On the Closing Date, Legacy LanzaTech and AMCI consummated the previously announced Business Combination pursuant to the Merger Agreement, by and among Legacy LanzaTech, AMCI and Merger Sub. As contemplated by the Merger Agreement, Merger Sub merged with and into Legacy LanzaTech, with Legacy LanzaTech continuing as the surviving corporation and as a wholly owned subsidiary of AMCI. On the Closing Date, AMCI changed its name to LanzaTech Global, Inc.

Immediately prior to the Business Combination, all issued and outstanding shares of preferred stock of Legacy LanzaTech were automatically converted into shares of common stock based on the applicable conversion ratio.

The number of shares of the common stock payable in the Business Combination in respect of each share of Legacy LanzaTech capital stock were determined based on the applicable exchange ratio of 4.374677 (the "Exchange Ratio"). In addition, the accumulated dividends payable to the holders of Legacy LanzaTech preferred shares were settled by delivery of the common stock, as part of the merger consideration.

Pursuant to the Merger Agreement, at the effective time of the Business Combination (the "Effective Time"):

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• each warrant to purchase Legacy LanzaTech common stock that was outstanding and unexercised immediately prior to the Effective Time and would automatically be exercised or exchanged in full in accordance with its terms by virtue of the occurrence of the Business Combination, was automatically exercised or exchanged in full for the applicable shares of Legacy LanzaTech capital stock, and each such share of Legacy LanzaTech common stock was treated as being issued and outstanding immediately prior to the Effective Time and was cancelled and converted into the right to receive the applicable number of shares of common stock;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• each LanzaTech warrant that was outstanding and unexercised prior to the Effective Time and was not automatically exercised in full as described above was converted into a warrant to purchase shares of common stock, in which case (a) the number of shares underlying such warrant was determined by multiplying the number of shares of Legacy LanzaTech capital stock subject to such warrant immediately prior to the Effective Time, by the Exchange Ratio, and (b) the per share exercise price of such warrant was determined by dividing the per share exercise price of such warrant immediately prior to the Effective Time by the Exchange Ratio, except that in the case of the AM Warrant, such exercise price is $10.00;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the extent not converted in full immediately prior to the Effective Time, the Brookfield SAFE was assumed by LanzaTech and convertible into shares of common stock; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• each option to purchase shares of Legacy LanzaTech common stock outstanding as of the Effective Time was converted into an option to purchase a number of shares of common stock (rounded down to the nearest whole share) equal to the product of (i) the number of shares of Legacy LanzaTech common stock subject to such option multiplied by (ii) the Exchange Ratio. The exercise price of such options is equal to the quotient of (a) the exercise price per share of such option in effect immediately prior to the Effective Time divided by (b) the Exchange Ratio.

In connection with the execution of the Merger Agreement, AMCI entered into subscription agreements (as amended on December 7, 2022, the "Initial Subscription Agreements") with certain investors (the "Initial PIPE Investors"). AMCI entered into additional subscription agreements with certain institutional and accredited investors (the "PIPE Investors") on October 8, 2022 (as amended on December 7, 2022) and February 6, 2022 (collectively, the "PIPE Subscription Agreements" and together with the subscription agreement between AMCI and ArcelorMittal, the "Subscription Agreements"). Pursuant to the Subscription Agreements, the PIPE Investors purchased an aggregate of 18,500,000 shares of common stock (the "PIPE Shares") in a private placement at a price of $10.00 per share for an aggregate purchase price of $185 million (the "PIPE Investment"). Such aggregate number of shares and aggregate purchase price include 3,000,000 shares of common stock issued to ArcelorMittal pursuant to the AM SAFE with Legacy LanzaTech, as a result of which such PIPE Investor entered into a Subscription Agreement prior to the closing of the Business Combination. The PIPE Investment was consummated in connection with the consummation of the Business Combination.

**Implications of Being an Emerging Growth Company and a Smaller Reporting Company** 

We are an emerging growth company, as defined in the Jumpstart Our Business Startups Act of 2012, and therefore we intend to take advantage of certain exemptions from various public company reporting requirements, including not being required to have our internal control over financial reporting audited by our independent registered public accounting firm pursuant to Section 404(b) of the Sarbanes-Oxley Act of 2002 (the "Sarbanes-Oxley Act"), reduced disclosure obligations regarding executive compensation in this prospectus, our periodic reports and our proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and any golden parachute payments not previously approved. We will remain an emerging growth company until the earlier of (1) December 31, 2026 (the last day of the fiscal year following the fifth anniversary of the consummation of AMCI's initial public offering), (2) the last day of the fiscal year in which we have total annual gross revenues of at least $1.235 billion, (3) the last day of the fiscal year in which we are deemed to be a "large accelerated filer," as defined in the Securities Exchange Act of 1934, as amended (the "Exchange Act"), and (4) the date on which we have issued more than $1.0 billion in nonconvertible debt securities during the prior three-year period.

<u>[**Table of Contents**](#ib82e114cd19f45afae73e7a64e42f208_1390)</u>

We are also a smaller reporting company as defined in the Exchange Act. We may continue to be a smaller reporting company even after we are no longer an emerging growth company. We may take advantage of certain of the scaled disclosures available to smaller reporting companies including, among other things, providing only two years of audited financial statements. We will remain a smaller reporting company for so long as (1) the market value of common stock held by non-affiliates is less than $250 million as of the last business day of the second fiscal quarter, or (2) our annual revenues in our most recent fiscal year completed before the last business day of our second fiscal quarter are less than $100 million and the market value of common stock held by non-affiliates is less than $700 million as of the last business day of the second fiscal quarter.

| Exercise price of the AM Warrant | $10.00 per share, subject to adjustment. |
| Exercise prices of the Options | The Options have exercise prices ranging between $1.07 per share and $3.15 per share. |

|:---|:---|
| | If the market price for shares of common stock is less than the exercise price of a holder's warrant, the AM Warrant or the Options, such holder may be less likely to exercise the warrants, the AM Warrant or the Options, as applicable, as such holder would be selling at a loss if they sold their common stock. Subject to adjustment, the exercise price of the warrants is $11.50 per share and the exercise price of the AM Warrant is $10.00 per share. The exercise prices of the Options range from $1.07 per share to $3.15 per share. Additionally, on February 10, 2023 the last reported sales price of the common stock was $7.30 per share. If the market price for shares of common stock is less than $10.00 per share, holders of shares of common stock would be selling at a loss if they purchased the shares of common stock at $10.00 per share. Because certain selling stockholders purchased shares privately at a price below the current market price, they may have an incentive to sell shares of their common stock because they could profit despite the market price of common stock falling below $10.00 per share. While these selling stockholders may, on average, experience a positive rate of return based on the current market price, public securityholders may not experience a similar rate of return on the securities they purchased due to differences in the purchase prices and the current market price. For example, based on the closing price of our common stock of $7.30 on February 10, 2023, the Sponsor and the former holders of all of the shares of AMCI Class B common stock (which converted into our common stock at the closing of the Business Combination), including certain former AMCI directors and officers (all of the foregoing, the "AMCI Insiders") would have a potential profit of up to approximately $7.29 per share that they purchased prior to the initial public offering of AMCI, or up to approximately $14.8 million in the aggregate (not giving effect to the issuance of common stock issuable upon exercise of the warrants held by them). |
| **Resale of common stock and warrants** |  |
| Shares of common stock offered by the selling stockholders | Up to (i) 18,500,000 PIPE Shares, (ii) up to 4,774,276 shares of common stock exercisable on the Private Placement Warrants, (iii) up to 5,000,000 shares of common stock pursuant to the Brookfield SAFE, (iv) up to 300,000 shares of common stock that are issuable upon exercise of the AM Warrant, (v) up to 2,164,839 shares of common stock held by certain selling stockholders, (vi) up to 1,680,683 shares of common stock underlying the Options held by certain selling stockholders, (vii) up to 5,916,514 shares of common stock purchased by certain selling stockholders subject to the Forward Purchase Agreement, and (viii) up to 160,482,211 shares of common stock required to be registered pursuant to the Registration Rights Agreement. |
| Warrants offered by the selling stockholders | Up to 4,774,276 Private Placement Warrants |
| Redemption | The Private Placement Warrants are redeemable in certain circumstances. See "Description of Securities" for further discussion. |
| Use of Proceeds | We will not receive any proceeds from the sale of the Private Placement Warrants or of the common stock by the selling stockholders pursuant to this prospectus. |

**RISK FACTORS**

*An investment in our equity securities involves a high degree of risk. Before you make a decision to buy our equity securities, in addition to the risks and uncertainties discussed in the section titled "Forward-Looking Statements," you should carefully consider the risks and uncertainties described below, together with all of the other information contained in this prospectus, including our financial statements and related notes appearing at the end of this prospectus and in the section titled "Management's Discussion and Analysis of Financial Condition and Results of Operations." If any of the events or developments described below were to occur, our business, prospects, operating results and financial condition could suffer materially, the trading price of our equity securities could decline and you could lose all or part of your investment. The risks and uncertainties described below are not the only ones we face. Additional risks and uncertainties not presently known to us or that we currently believe to be immaterial may also adversely affect our business.* 

**Summary of Risk Factors** 

The following is a summary of principal risk to which our business, operations and financial performance are subject. Each of these risks is more fully described in the individual risk factors immediately following this summary.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We have incurred losses and anticipate continuing to incur losses, and have not yet generated material revenues from marketing of CarbonSmart™ products and sale of equipment.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The success of our plant operations is significantly dependent upon the strong execution and operation of each project by the respective industry partner as we rely, and expect to continue to rely, heavily on industry partners to effect our growth strategy and to execute our business plan, and our failure to successfully maintain and manage these relationships and enter into new relationships could prevent us from achieving or sustaining profitability.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Fluctuations in the prices of waste-based feedstocks used to manufacture the products produced using our process technologies, the price of fossil feedstocks relative to the price of our waste-based feedstocks, and the availability of the waste-based feedstocks may affect our or our industry partners' cost structure, gross margin and ability to compete.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We compete in an industry characterized by rapidly advancing technologies, intense competition and a complex intellectual property landscape, and our failure to successfully compete with other companies in our industry may have a material adverse effect on our business, financial condition and results of operations and market share.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We may require substantial additional financing to fund our operations and complete the development and commercialization of the process technologies that produce each of our products or new aspects of our existing process technologies that produce each of our products, and we may not be able to do so on favorable terms.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Even if we successfully develop process technologies that produce products meeting our industry partners' specifications, the adoption of such process technologies by our industry partners may be delayed or reduced, or our costs may increase.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Failure of LanzaJet to complete its initial facility or failure of third parties to adopt the LanzaJet process in their commercial facilities for the production of sustainable aviation fuel ("SAF") could result in us never owning a majority stake in LanzaJet and may severely impact our business, financial condition, results of operations and prospects.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Governmental programs designed to incentivize the production and consumption of low-carbon fuels and carbon capture and utilization, may be implemented in a way that does not include products produced using our novel technology platform and process technologies or could be repealed, curtailed or otherwise

------

<u>[**Table of Contents**](#ib82e114cd19f45afae73e7a64e42f208_1390)</u>

changed, which would have a material adverse effect on our business, results of operations and financial condition.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Political and economic uncertainty, including changes in policies of the Chinese government or in relations between China and the United States, may impact our revenue and materially and adversely affect our business, financial condition, and results of operations.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Our ability or the ability of our partners to operate in China may be impaired by changes in Chinese laws and regulations, including those relating to taxation, environmental regulation, restrictions on foreign investment, and other matters, which can change quickly with little advance notice.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Our operations and financial results may be impacted if the PRC government determines that the contractual arrangements constituting part of the Shougang Joint Venture variable interest entity ("VIE") structure do not comply with PRC regulations, or if these regulations change or are interpreted differently in the future.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We and our partners may be subject to regulatory actions by the Chinese government targeting concerns related to data security and monopolistic behavior.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Changes in China's economic, political or social conditions or legal system or government policies could have a material adverse effect on our business and operations.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We may be subject to risks that the Chinese government may intervene or influence our operations at any time.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We and our industry partners are subject to extensive international, national and regional laws and regulations, and any changes in laws or regulations, or failure to comply with these laws and regulations, could have a material adverse effect on our business.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Our business, results of operations and financial condition have been, and could continue to be, adversely affected by the COVID-19 pandemic. Causes of supply chain challenges, including COVID-19, could result in delays or increased costs for us and our partners deploying our technologies.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Market prices for more sustainable, waste-based products that our process technologies enable are subject to volatility and there is a limited referenceable market for such products.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Our patent rights and trade secrets protections may not provide commercially meaningful protection against competition, and we may not be able to operate our business without infringing the proprietary rights of third parties.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• There can be no assurance that our warrants will be in the money at the time they become exercisable, and they may expire worthless.

**Risks Related to Our Business and Industry**

***Our business, results of operations and financial condition have been, and could continue to be, adversely affected by the COVID-19 pandemic.***

The ongoing COVID-19 pandemic has impacted our business and we expect it to continue to do so. Governments and businesses have taken, and may continue to take, unprecedented measures in response to the COVID-19 pandemic. Such measures have included restrictions on travel and business operations, temporary closures of businesses, and quarantines and shelter-in-place orders. The COVID-19 pandemic has caused significant volatility and disruption in global financial markets.

------

<u>[**Table of Contents**](#ib82e114cd19f45afae73e7a64e42f208_1390)</u>

The COVID-19 pandemic and the measures taken by many countries in response have had an adverse impact on, and could continue to adversely impact, our business, results of operations and financial condition. These actions include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• disruption in demand for the products produced using our process technologies, which has resulted and may continue to result in a decline in the prices we and our industry partners have been able to charge for the sale of such products;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• effects on our industry partners' and potential industry partners' ability or willingness to invest in new technologies or to work with us;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a slow-down in the construction of manufacturing facilities for our technology platform;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• delays in the delivery of the products produced using our process technologies;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a reduction in government grants and related funding for research and development;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• limitations on our ability to operate our business as a result of federal, state or local regulations imposed as a result of COVID-19; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• limitations on our industry partners' ability to conduct partnering activities in a timely manner.

We believe the aforementioned factors impact our revenues directly in instances where we participate in projects with industry partners under our co-development model, and indirectly in instances where we are party to licensing agreements with industry partners and collect lower royalty fees.

The full extent of the impact of the COVID-19 pandemic on our operational and current and future financial performance is currently uncertain and will depend on many factors outside our control, including, without limitation, the timing, extent, trajectory and duration of the pandemic, the availability of effective treatments and vaccines, the emergence, severity and spread of potential variants of the virus that causes COVID-19, the imposition of and compliance with protective public safety measures, and the impact of the pandemic on the global economy and on the demand for the products produced using our process technologies and our ability to maintain current and foster new relationships with our industry partners. We are continuing to monitor the situation and take appropriate actions in accordance with the recommendations and requirements of relevant authorities.

***We have incurred losses and anticipate continuing to incur losses.***

We have not achieved operating profitability in any quarter since our formation. Our net losses after tax were approximately $55.0 million for the nine months ended September 30, 2022, and $30.6 million for the nine months ended September 30, 2021. As of September 30, 2022, we had an accumulated deficit of $434.9 million. We anticipate that we will continue to incur losses until we can sufficiently commercialize our process technologies. We cannot guarantee when we will operate profitably, if ever. The profitability of products produced using our process technologies depends largely on manufacturing costs and the market prices of the products produced using our process technologies. In the case of the partners with which we have entered licensing agreements, the prices they are able to charge impact the royalty fees we derive from their revenues. We must sustain the relationships we have developed with our current partners and successfully establish relationships with new partners to which we can license our proprietary technologies or with whom we can co-develop plants, and we must continue to find ways to further enhance our technology platform and product portfolio. If we are unable to successfully take these steps, we may never operate profitably, and, even if we do achieve profitability, we may be unable to sustain or increase our profitability in the future.

***The success of our plant operations is significantly dependent upon the strong execution and operation of each project by the respective industry partner as we rely, and expect to continue to rely, heavily on industry partners to effect our growth strategy and to execute our business plan. Our failure to successfully maintain and manage these relationships and enter into new relationships could delay our anticipated timelines, prevent the successful development and commercialization of products produced using our process technologies, negatively impact our financial results and prevent us from achieving or sustaining profitability.***

Our ability to successfully maintain and manage partnering arrangements and enter into new partnering arrangements are critical factors to the success of our business and growth. We rely, and expect to continue to rely, heavily on such arrangements. We have limited or no control over the amount or timing of resources that any third party commits to negotiating a partnering arrangement with us or, if negotiated and entered into, the timing or amount of resources that a third party will commit to our projects. Any third party with which we are in negotiations may experience a change of policy or priorities and may discontinue negotiations with us. Any of our industry partners may fail to perform their obligations as expected. These industry partners may breach or terminate their agreements with us or otherwise fail to conduct their partnering activities successfully and in a timely manner. Further, our industry partners may not develop commercially viable products in connection with our partnering arrangements or devote sufficient resources to the development, manufacture, marketing and sale of products produced using our process technologies. Moreover, disagreements with an industry partner could develop, and any such conflict could reduce our ability to enter into future partnering agreements and negatively impact our relationships with one or more existing industry partners. Any of these events could delay our anticipated timelines, prevent the successful development and commercialization of products produced using our process technologies, negatively impact our financial results, and prevent us from ever achieving or sustaining profitability. These negative consequences could be augmented in the event that we are forced to seek replacement partners.

Our current and future partnering opportunities could be harmed if:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• we do not achieve our objectives under our arrangements in a timely manner, or at all;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• we disagree with our industry partners as to rights to intellectual property we jointly develop or that they must license from us, or as to their research programs or commercialization activities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• we are unable to successfully manage multiple partnering arrangements occurring at the same time;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• applicable laws, regulations or state actors, domestic or foreign, impede our ability to enter into strategic arrangements;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• we develop processes or enter into additional partnering arrangements that conflict with the business objectives of our other arrangements;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our industry partners become competitors of ours or enter into agreements with our competitors; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• consolidation in our target markets limits the number of potential industry partners.

Additionally, because we have entered into exclusive arrangements with industry partners, other potential partners in our industry may choose to compete against us, rather than partner with us. This may limit our partnering opportunities and harm our business and prospects. Our business also could be negatively impacted if any of our industry partners undergoes a change of control or assigns the rights or obligations under any of our agreements. If any of our industry partners were to assign these agreements to our competitors or to a third party who is not willing to work with us on the same terms or commit the same resources as the current industry partner, our business and prospects could be adversely affected.

***Even if we are successful in entering into strategic partnering arrangements, there are a number of different arrangements that we can pursue, and there are no assurances that we will select and negotiate the best arrangements for us and our stockholders.***

We seek to commercialize our process technologies by pursuing licensing arrangements in some markets and seek arrangements to co-develop projects in others. Our business strategy is based on a wide variety of factors,

------

<u>[**Table of Contents**](#ib82e114cd19f45afae73e7a64e42f208_1390)</u>

including the size and competitive environment in each market, and our perceived ability to best monetize our proprietary technology. The types of arrangements we enter into with our industry partners will be significant in determining the amount of risk and control that we maintain with respect to the development and commercialization of products produced using our process technologies. The contractual arrangements with our industry partners will also determine the amount of capital we need to contribute to a particular project, as well as the revenue we may receive and the margins associated with any sale of products produced using our process technologies. We will need to analyze these issues properly and negotiate corresponding arrangements with our industry partners to efficiently balance the amount of risk we take, the level of control we maintain and the amount of revenues and margins we obtain with respect to the products produced using our process technologies. There are no assurances that we will select and negotiate the best arrangements for us and our stockholders. Failure to choose optimal arrangements could result in delays or failures in the commercial development of certain products produced using our process technologies, sub-optimal economic returns and capital commitments that negatively impact our business, and our ability to successfully pursue multiple opportunities in parallel.

***We have entered into and anticipate entering into non-binding letters of intent, side letters, memoranda of understanding, term sheets and other arrangements with potential industry partners and cannot assure you that such arrangements will lead to definitive agreements. If we are unable to complete these arrangements in a timely manner and on terms favorable to us, our business will be adversely affected.***

We have engaged in negotiations with a number of companies and have agreed to preliminary terms regarding the development and commercialization of certain products produced using our process technologies. We may be unable to negotiate final terms in a timely manner, or at all, and there is no guarantee that the terms of any final, definitive, binding agreement will be the same or similar to those currently contemplated in a preliminary agreement. Final terms may be less favorable to us than those set forth in the preliminary agreements. Delays in negotiating final, definitive, binding agreements could slow the development and commercialization of products produced using our process technologies. Failure to agree to final terms for the development and commercialization of such products could prevent us from growing our business, result in wasted resources and cause us to consume capital significantly faster than we currently anticipate.

***We continue to face significant risks associated with our international expansion strategy.***

We are continuing to seek new opportunities to produce and commercialize products using our process technologies outside the United States through entering into licensing and co-development arrangements with new and existing industry partners. Our international business operations are subject to a variety of risks, including:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• challenges associated with operating in diverse cultural and legal environments, including legal restrictions that impact our ability to enter into strategic partnering arrangements;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the need to comply with a variety of U.S. laws applicable to the conduct of overseas operations, including export control laws and the Foreign Corrupt Practices Act and local law requirements;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our ability, or reduced ability, to protect our intellectual property in certain countries;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• potential for longer sales cycles in certain countries;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• changes in or interpretations of foreign rules and regulations that may adversely affect our or our industry partners' ability to produce or sell products manufactured using our process technologies or repatriate profits to the United States;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• economic, political or social instability in foreign countries;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• changes in demand for products produced using our process technologies in international markets;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the imposition of tariffs and other foreign taxes;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the imposition of limitations on, or increase of, withholding and other taxes on remittances and other payments by foreign subsidiaries or joint ventures;

------

<u>[**Table of Contents**](#ib82e114cd19f45afae73e7a64e42f208_1390)</u>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• limitations on the production or movement of genetically engineered products or processes and the production or sale of products or processes manufactured using genetically engineered products, into, out of and within foreign countries; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the availability of government subsidies or other incentives that benefit competitors in their local markets that are not available to us.

Our inability to overcome these obstacles could harm our business, financial condition and operating results. Even if we are successful in managing these obstacles, our industry partners internationally are subject to these same risks and may not be able to manage these obstacles effectively.

***Construction of our or our partners' plants may not be completed in the expected timeframe or in a cost-effective manner. Any delays in the construction of plants could severely impact our business, financial condition, results of operations and prospects.***

Our projected financial performance and results of operations depend on our ability and our partners' abilities to construct several commercial scale plants. With respect to these future plants, we and our partners also do not have agreements with engineering, procurement or construction firms. Consequently, we cannot predict on what terms such firms may agree to design and construct future plants.

If we and our partners are unable to construct these plants within the planned timeframes, in a cost-effective manner or at all due to a variety of factors, including, but not limited to, a failure to acquire or lease land on which to build plants, a stoppage of construction as a result of the COVID-19 pandemic, the imposition or heightening of sanctions or other economic or military measures in relation to the current Russia-Ukraine conflict, unexpected construction problems, permitting and other regulatory issues, severe weather, labor disputes, and issues with subcontractors or vendors, including payment disputes, our business, financial condition, results of operations and prospects could be severely impacted.

The construction and commission of any new project is dependent on a number of contingencies some of which are beyond our and our partners' control. There is a risk that significant unanticipated costs or delays could arise due to, among other things, errors or omissions, unanticipated or concealed project site conditions, including subsurface conditions and changes to such conditions, unforeseen technical issues or increases in plant and equipment costs, insufficiency of water supply and other utility infrastructure, or inadequate contractual arrangements. Should these or other significant unanticipated costs arise, this could have a material adverse impact on our business, financial condition, results of operations and prospects. No assurance can be given that construction will be completed on time or at all, or as to whether we and our partners will have sufficient funds available to complete construction.

***Failure to continuously reduce operating and capital costs for our and our partners' facilities that deploy our process technologies may impact adoption of our process technologies and could severely impact our business, financial condition, results of operations and prospects.***

As of the date of this prospectus, 12 commercial facilities are either in engineering or under construction utilizing our technology. We anticipate the deployment of numerous commercial facilities to accelerate the commercialization of our process. If we are unable to adequately reduce and control the operating and capital costs of our and our partners' facilities that deploy our process technologies, we will be unable to realize manufacturing volume and cost targets. We and our partners may have to significantly reduce our spending, delay or cancel our planned activities or substantially change our current business model. This could reduce the market adoption of our process technologies and products, damage our reputation with current or prospective industry partners and investors, and harm our business, financial condition, results of operations and prospects.

***Maintenance, expansion and refurbishment of our and our partners' facilities, the construction of new facilities and the development and implementation of our new process technologies or new aspects of our existing process technologies involve significant risks.***

Our facilities and our partners' facilities may require regular or periodic maintenance, upgrading, expansion, refurbishment or improvement. Any unexpected operational or mechanical failure, including failure associated with

------

<u>[**Table of Contents**](#ib82e114cd19f45afae73e7a64e42f208_1390)</u>

breakdowns and forced outages, could reduce the facilities' production capacity below expected levels, which would reduce our and our partners' production capabilities and ultimately our revenues. Unanticipated capital expenditures associated with maintaining, upgrading, expanding, repairing, refurbishing, or improving facilities may also reduce our profitability. Our facilities and our partners' facilities may also be subject to unanticipated damage as a result of natural disasters, terrorist attacks or other events.

If we or our partners make any major modifications to facilities, such modifications likely would result in substantial additional capital expenditures and could prolong the time necessary to bring the facility online. We or our partners may also choose to refurbish or upgrade facilities based on our assessment that such activity will provide adequate financial returns. However, such activities require time for development and capital expenditures before commencement of commercial operations, and key assumptions underpinning a decision to make such an investment may prove incorrect, including assumptions regarding construction costs and timing, which could harm our business, financial condition, results of operations and cash flows.

The construction of new manufacturing facilities entails a number of risks and assumptions, including the ability to begin production within the cost and timeframe estimated and to attract a sufficient number of skilled workers to meet the needs of the new facility. Additionally, our and our partners' assessment of the projected benefits associated with the construction of new manufacturing facilities is subject to a number of estimates and assumptions, which in turn are subject to significant economic, competitive and other uncertainties that are beyond our control. If we or our partners experience delays or increased costs, our estimates and assumptions are incorrect, or other unforeseen events occur, our business, ability to supply our industry partners, financial condition, results of operations and cash flows could be adversely impacted.

Finally, we may not be successful or efficient in developing or implementing new processes technologies or new aspects of our existing process technologies. Innovation in production processes involves significant expense and carries inherent risks, including difficulties in designing and developing new process technologies, development and production timing delays, lower than anticipated manufacturing yields, and product defects. Disruptions in the production process can also result from errors, defects in materials, delays in obtaining or revising operating permits and licenses, returns of product from our industry partners, interruption in our supply of materials or resources, and disruptions at our or our partners' facilities due to accidents, maintenance issues, or unsafe working conditions, all of which could affect the timing of production ramps and yields. Production issues can lead to increased costs and may affect our and our partners' ability to meet product demand, which could adversely impact our business and results from operations.

***Our commercial success may be influenced by the price of fossil feedstocks relative to the price of our waste-based feedstocks.***

Our commercial success may be influenced by the cost of our and our partners' products produced using our process technologies relative to fossil feedstock-based products. The cost of fossil feedstock-based products is in part based on the price of fossil feedstocks, which are subject to historically fluctuating prices. If the price of waste-based feedstocks increases and/or the price of fossil feedstocks decreases, products produced using our process technologies may be less competitive relative to fossil feedstock-based products. A material decrease in the cost of conventional fossil feedstock-based products may require a reduction in the prices of products produced using our process technologies for them to remain attractive in the marketplace and may negatively impact our revenues.

***Fluctuations in the prices of waste-based feedstocks used to manufacture the products produced using our process technologies may affect our or our industry partners' cost structure, gross margin and ability to compete.***

The cost to produce the products we commercialize with our industry partners is highly dependent on the cost and usage of various waste-based feedstocks. The prices of many of these feedstocks are cyclical and volatile. An increase in the price of the waste-based feedstocks used to manufacture the products produced using our process technologies would likely change our or our industry partners' cost structure and impact our gross margin. At certain levels, waste-based feedstock prices may make the products produced using our process technologies uneconomical to manufacture.

------

<u>[**Table of Contents**](#ib82e114cd19f45afae73e7a64e42f208_1390)</u>

Although there may be indices that show the pricing of the feedstock used for production that closely track to products produced using our process technologies, there are no assurances that these indices will be valid or, if valid, that current prices will not later change. In addition, we may underestimate the volume of feedstock required to operate at commercial scale. For example, although the feedstock usage quantities are based on predictable chemical reactions, the actual consumption required to produce SAF on a commercial scale may be greater, affecting production cost and impacting production volumes. We cannot control the cost of these feedstocks, and we could underestimate feedstock pricing and volume requirements. These uncertainties could affect our costs, or the costs of our industry partners, and our gross margin. Although we believe that our process technologies can operate on multiple feedstocks in the event that prices of specific feedstocks fluctuate, we have not tested this on a commercial scale and cannot guarantee that feedstocks are interchangeable without requiring significant alterations to our process technologies.

***Declines in the prices of feedstocks our competitors use to produce their products could allow them to reduce the prices of their products, which could cause us or our industry partners to reduce the prices of the products produced using our process technologies. This could make it uneconomical for our partners to produce products using our process technologies.***

The cost to produce the products our competitors and our industry partners' competitors are commercializing and attempting to commercialize is highly dependent on the cost and usage of various feedstocks. The cost to produce ethanol by our competitors is highly dependent on the prices of corn, sorghum, barley, sugar cane and sugar beets. The prices of many of these feedstocks are cyclical and volatile. Declines in the prices of the feedstocks our competitors use to produce their products could allow our competitors to reduce the prices of their products. This in turn could cause our industry partners to have to reduce the prices of any competing products that are commercialized using our process technologies, or make it uneconomical for our partners to produce products using our process technologies, which would reduce the revenues we generate in connection with our partners' sale of such products. Even the perception of future declines in the feedstocks our competitors utilize may adversely affect the prices our industry partners can obtain from our industry partners or prevent potential industry partners from entering into agreements to buy products produced using our process technologies.

***If the availability of the waste-based feedstocks used in our process technologies declines or competition for them increases, we or our business partners may experience delayed or reduced production or be required to raise the prices of the products produced using our process technologies, either of which could reduce the demand for the products produced using our process technologies and our revenue.***

The production of products using our process technologies will require large volumes of waste-based feedstocks. We cannot predict the future availability of any waste-based feedstock necessary to produce products using our process technologies. The supply of waste-based feedstocks might be impacted by a wide range of factors, including increased competition, weather conditions, natural disasters, droughts, floods, changes in the waste-producing industries, the imposition or heightening of sanctions or other economic or military measures in relation to the current Russia-Ukraine conflict, or government policies and subsidies. Declines in the availability of the waste-based feedstocks used to produce products using our process technologies could cause delays or reductions in production, increases in the prices of products produced using our process technologies, and reductions in demand for products produced using our process technologies, resulting in reduced revenue for us.

***We compete in an industry characterized by rapidly advancing technologies, intense competition and a complex intellectual property landscape, and our failure to successfully compete with other companies in our industry may have a material adverse effect on our business, financial condition and results of operations and market share.***

While we do not believe we have any direct competitors, there can be no assurance that we will not have direct competition in the future, that such competitors will not substantially increase the resources devoted to the development and marketing of their products and services that compete with us, or that new or existing competitors will not enter the market in which we are active.

We face substantial indirect competition from many different sources, including companies that enjoy competitive advantages over us, such as greater financial, research and development, manufacturing, personnel and

------

<u>[**Table of Contents**](#ib82e114cd19f45afae73e7a64e42f208_1390)</u>

marketing resources, greater brand recognition, stronger historical relationships with their customers and more experience and expertise in intellectual property rights and operating within certain international locations.

These competitors may introduce competing products without our prior knowledge and without our ability to take preemptive measures in anticipation of their commercial launch. Competition may increase further as a result of greater availability of capital for investment and increased interest in our industry as more companies seek to facilitate the development of a circular carbon economy. Our competitors may succeed in developing, acquiring or licensing on an exclusive or non-exclusive basis technologies that are more effective or less costly than those we have developed. Our failure to successfully compete may have a material adverse effect on our business, financial condition and results of operations and diminish our market share.

***Technological innovation by others could render our technology and the products produced using our process technologies obsolete or uneconomical.***

The fuel and chemical industries are characterized by rapid and significant technological change. Our success will depend on our ability to maintain a competitive position with respect to technological advances. Our technology and the products derived from our technology may be rendered obsolete or uneconomical by technological advances by others, more efficient and cost-effective products, or entirely different approaches developed by one or more of our competitors or other third parties. Though we plan to continue to expend significant resources to enhance our technology platform and processes, there are no assurances we will be able to keep pace with technological change.

***Our financial results could vary significantly from quarter to quarter and are difficult to predict.***

Our financial results could vary significantly from quarter to quarter because of a variety of factors, many of which are outside of our control and are difficult to predict. As a result, comparing our results of operations on a period-to-period basis may not be meaningful. In addition to the risk factors stated herein, other factors that could cause our quarterly results of operations to fluctuate include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• achievement of, or failure to achieve, technology or product development milestones needed to allow us to enter identified markets on a timely and cost-effective basis;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• delays or greater than anticipated expenses associated with the scale-up and the commercialization of process technologies to produce new products;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• changes in the amount that we invest to develop, acquire or license new technologies and processes;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our ability to successfully enter into partnering arrangements, and the terms of those relationships (including levels of related capital contributions);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• fluctuations in the prices or availability of the feedstocks required to produce products using our process technologies or those of our competitors;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• changes in the size and complexity of our organization, including our expanded operations as a public company;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• changes in general economic, industry and market conditions, both domestically and in our foreign markets;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• business interruptions, including disruptions in the production process at any facility where products produced using our process technologies are manufactured;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• departure of executives or other key management employees;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• changes in the needs for the products produced using our process technologies;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the development of new competitive technologies or products by others and competitive pricing pressures;

------

<u>[**Table of Contents**](#ib82e114cd19f45afae73e7a64e42f208_1390)</u>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the timing, size and mix of sales to our industry partners for products produced using our process technologies;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• seasonal production and the sale of products produced using our process technologies; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• changes in governmental, accounting and tax rules and regulations, environmental, health and safety requirements, and other rules and regulations.

Due to these and other factors, our financial results for any quarterly or annual period may not meet our expectations or the expectations of our investors and may not be meaningful indications of our future performance.

***Our financial projections may differ materially from actual results.***

Our financial projections are based on our estimates and assumptions concerning various factors which are subject to significant risks and uncertainties, many of which are beyond our control, and therefore actual results may differ materially. These estimates and assumptions include, among others: estimates of the total addressable market for products produced using our process technologies; assumptions regarding industry partner demand and performance under existing agreements and industry partner agreements currently under negotiation; estimates of the rate at which project starts can be achieved; assumptions regarding our ability to identify and convert new customers; estimates of our ability to retain and add capacity with existing customers; assumptions regarding our ability to negotiate and structure product offtake; estimates of the rate and timelines at which certain project development milestones can be achieved; assumptions regarding our ability to scale production to meet current and future demand; and assumptions regarding research, product development, product timelines, operational execution and demand. These estimates and assumptions are subject to various factors beyond our control, including, for example, changes in industry partner demand, changes in the supply of feedstock, increased construction costs for our plants, changes in the regulatory environment, the impact of global health crises (including the COVID-19 pandemic), the imposition or heightening of sanctions or other economic or military measures in relation to the current Russia-Ukraine conflict, and changes in our executive team. Notably, our financial projections reflect assumptions regarding contracts that are currently under negotiation with, as well as indications of interest from, potential industry partners who may withdraw at any time. Accordingly, our future financial condition and results of operations may differ materially from our projections and expectations. Our failure to achieve our projected results could harm the trading price of our securities and our financial position.

***We may require substantial additional financing to fund our operations and complete the development and commercialization of the process technologies that produce each of our products or new aspects of our existing process technologies that produce each of our products, and we may not be able to do so on favorable terms.***

Our operations have consumed substantial amounts of cash since inception, and we expect to substantially increase our spending, in particular, as we:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• enter into and engage in strategic partnering arrangements to produce products cost-effectively at acceptable quality levels and price points, including making capital contributions for the construction of certain plants;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• invest in developments with respect to our existing process technologies in order to increase their effectiveness or reduce related capital expenditures;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• expand our research and development efforts;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• grow our business organization;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• pursue select co-development opportunities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• seek to identify additional market opportunities for the products produced using our process technologies; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• pursue partnering arrangements.

------

<u>[**Table of Contents**](#ib82e114cd19f45afae73e7a64e42f208_1390)</u>

We believe our existing cash and cash equivalents will be sufficient to fund our operations for at least 12 months from the date of this prospectus. However, changing circumstances may cause us to consume capital significantly faster than we currently anticipate, and we may need to spend more money than currently expected because of circumstances beyond our control. Moreover, we and our industry partners may experience delays in the production of commercial quantities of products, in a manner that is cost-effective and at suitable quality levels, which would postpone our ability to generate revenue associated with the sale of such products. Securing additional financing could require a substantial amount of time and attention from our management and may divert a disproportionate amount of its attention away from our business activities, which may adversely affect our ability to conduct our day-to-day operations. In addition, we cannot guarantee that future financing will be available in sufficient amounts or on terms acceptable to us, if at all. If we are unable to raise additional capital when required or on acceptable terms, we may be required to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• delay or suspend some or all of our commercialization efforts;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• decrease or abandon some or all of our research and development efforts;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• decrease the financial resources dedicated to our partnering efforts, which may substantially postpone the development, manufacture, marketing or sale of existing and future products produced using our process technologies; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• suspend the growth of our organization.

To raise additional funds to support our business operations, we may sell additional equity, or convertible debt securities, which would result in the issuance of additional shares of our capital stock and dilution to our stockholders. The incurrence of indebtedness would result in increased fixed payment obligations and could also result in certain restrictive covenants, such as limitations on our ability to incur additional debt, limitations on our ability to acquire, sell or license intellectual property rights and other operating restrictions that could adversely impact our ability to conduct our business. If we are unable to raise additional capital in sufficient amounts or on terms acceptable to us, we will be prevented from pursuing discovery, development and commercialization efforts and our ability to generate revenues and achieve or sustain profitability will be substantially harmed.

***If we are unable to manage our growth and expand our operations successfully, our reputation and brand may be damaged and our business and results of operations may be harmed.***

Over the past several years, we have experienced significant expansion of our business. We expect this growth to continue and accelerate in the future in connection with our commercialization efforts, expanded research and development activities, and as we transition to operating as a public company. Our ability to effectively manage our anticipated growth and expansion of our operations will require us to do, among other things, the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• enhance our operational, financial and management controls and infrastructure, human resource policies, and reporting systems and procedures;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• effectively scale our operations;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• successfully identify, recruit, hire, train, maintain, motivate and integrate additional employees;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• expand our facilities and equipment; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• effectively manage and maintain our corporate culture.

These enhancements and improvements will require significant capital expenditures and allocation of valuable management and employee resources, and our growth will continue to place a strain on our operational, financial and management infrastructure. Our future financial performance and our ability to execute on our business plan will depend, in part, on our ability to effectively manage any future growth and expansion. There are no guarantees we will be able to do so in an efficient or timely manner, or at all. Our failure to effectively manage growth and expansion could have a material adverse effect on our business, results of operations, financial condition, prospects and reputation.

***If we lose key personnel or are unable to attract, integrate and retain additional key personnel, it could harm our research and development efforts, delay the commercialization of the new process technologies or the new aspects of our existing process technologies, delay the launch of process technologies in our development pipeline and impair our ability to meet our business objectives.***

Our business involves complex operations spanning a variety of disciplines and demanding a management team and employee workforce that is knowledgeable in the many areas necessary for our operations. The loss of any key member of our management team or key research and development or operational employees, or the failure to attract and retain such employees, could prevent us from developing and commercializing new process technologies or the new aspects of our existing process technologies, delay the launch of process technologies in our development pipeline and impair our ability to meet our business objectives.

We may not be able to attract or retain qualified employees due to the intense competition for qualified personnel among technology-based businesses, or due to the scarcity of personnel with the qualifications or experience necessary for our business. Hiring, training and successfully integrating qualified personnel into our operations can be a lengthy and expensive process, and efforts to integrate such personnel may not be successful. The market for qualified personnel is very competitive because of the limited number of people available with the necessary technical skills and understanding of our technology, and given the number of companies in this industry seeking this type of personnel. If we are not able to attract, integrate and retain the necessary personnel to accomplish our business objectives, we may experience staffing constraints that will adversely affect our ability to support our internal research and development programs. In particular, our production process development, process engineering, research and development, and plant operations programs are dependent on our ability to attract, integrate and retain highly skilled scientific, technical and operational personnel. Competition for such personnel from numerous companies and academic and other research institutions may limit our ability to do so on acceptable terms, or at all. As we continue to expand our international operations, these personnel-related risks will increase and we will face additional geography-specific challenges, such as challenges hiring, training, and relocating employees to specific regions or countries and differing tax and regulatory regimes.

***Even if we successfully develop process technologies that produce products meeting our industry partners' specifications, the adoption of such process technologies by our industry partners may be delayed or reduced, or our costs may increase, due to customer qualification, negative life cycle assessment or capital investment procedures.***

Even if the products produced using our process technologies are produced at contractual or targeted specifications, as the case may be, we or our industry partners may face delays or reduced demand for such products related to current or future customer qualification trials that could take several months, complicated life cycle assessments, or capital investment procedures. For the products produced using our process technologies to be accepted, our industry partners may need to test and certify them for use in their processes and, in some cases, determine whether products that contain the products produced using our process technologies satisfy additional third-party specifications. We may need to demonstrate to our industry partners that the products produced using our process technologies do not contain impurities that cause such products to behave differently than their traditional equivalents in a way that impacts their end-product quality. Our industry partners, in turn, may need to validate the use of the products produced using our process technologies for third parties. Our products may require lengthy and complex life cycle assessments to evaluate the potential environmental impacts of the products through their entire life cycles, covering all relevant inputs from, and emissions into, the environment. Our industry partners' customers may need to engage in capital investment procedures to assess their abilities to invest in our products, which may result in those customers determining not to allocate their resources to purchasing our products. Meeting these suitability standards could be a time-consuming and expensive process, and our industry partners may invest substantial time and resources into such qualification efforts without ultimately securing approval by their customers. This could materially and adversely impact our revenues until customer qualification, positive life cycle assessment or capital investment procedures are achieved and maintained.

***Failure of LanzaJet to complete its initial facility or failure of third parties to adopt the LanzaJet process in their commercial facilities for the production of SAF could result in us never owning a majority stake in LanzaJet and may severely impact our business, financial condition, results of operations and prospects.***

Pursuant to the LanzaJet Investment Agreement, described in more detail in the section entitled "*Business — Key Collaboration Agreements — LanzaJet Agreements — LanzaJet Amended and Restated Investment Agreement*," Mitsui, Suncor Energy Inc. ("Suncor"), British Airways PLC, a subsidiary of International Consolidated Airlines Group ("British Airways") and Shell Ventures LLC ("Shell") have committed to invest in LanzaJet a total of up to $120 million in second tranche investments upon the achievement of certain development milestones relating to an initial demonstration facility located at the LanzaTech Freedom Pines Biorefinery in Soperton, Georgia (the "Soperton facility"). Pursuant to the LanzaJet Investment Agreement, $45 million has already been invested in setting up LanzaJet and in constructing the Soperton facility. Our partners have likewise agreed to determine the feasibility of developing additional potential facilities for the commercial scale production of alcohol-to-jet ("ATJ") fuel.

Although LanzaJet is currently working with the partners mentioned above to confirm project locations and solidify the appropriate project structures, and we are developing projects ourselves to construct and operate facilities that would use the LanzaJet process, there is no guarantee that these facilities will be completed or that third parties will adopt the LanzaJet process in their commercial facilities for the production of SAF. The failure of LanzaJet to complete its initial facility or of third parties to adopt the LanzaJet process in their commercial facilities could severely impact our business, financial condition, results of operations and prospects.

Furthermore, we currently have a 25% voting interest in LanzaJet and are not currently able to make decisions on behalf of LanzaJet without support from other shareholders. We will remain a minority shareholder in LanzaJet unless we are issued shares pursuant to the LanzaJet Amended and Restated Investment Agreement upon the closing of at least two of the second tranche investments by any of Mitsui, Suncor, British Airways and Shell. The conditions for these second tranche investments include performance requirements at the Soperton facility, regulatory approvals, the negotiation of additional agreements and other conditions which are outside our control. These conditions have not been, and may never be, met. As such, we cannot guarantee when or whether we will become majority shareholders in, or exercise control over, LanzaJet at any time in the future.

***LanzaJet has an exclusive license to some of our intellectual property related to SAF.***

In connection with the LanzaJet Investment Agreement, we entered into an intellectual property and technology license agreement (the "LanzaJet License Agreement") with LanzaJet. Pursuant to the LanzaJet License Agreement, we granted to LanzaJet a perpetual, worldwide, non-transferrable, irrevocable, royalty-free, sublicensable, exclusive license to certain intellectual property related to the conversion of ethanol to fuel. This license is exclusive including as to us. With the exception of certain pre-existing SAF obligations and development projects for which we have already been granted sublicenses, we are unable to undertake new SAF production opportunities using the licensed intellectual property, or otherwise use such intellectual property for the conversion of ethanol to fuel, without the prior consent of LanzaJet while the LanzaJet License Agreement is in effect. We cannot guarantee that LanzaJet would grant such consent or otherwise agree to grant to us a license of intellectual property and our receipt thereof would depend on negotiations with our fellow shareholders of LanzaJet.

In connection with the LanzaJet Shareholder Loan described in more detail in the section entitled "*Certain Relationships and Related Party Transactions — Legacy LanzaTech Related Party Transactions — LanzaJet Shareholder Loan*," LanzaJet collaterally assigned its license from LanzaTech to secure the LanzaJet Freedom Pines Fuels LLC ("FPF") shareholder debt. In the event of a default by FPF, LanzaJet shareholders could prevent LanzaJet from funding FPF to cure its default and ultimately foreclose on LanzaJet's license.

***Our and our industry partners' failure to accurately forecast demand for any product produced using our process technologies could result in an unexpected shortfall or surplus that could negatively affect our results of operations.***

Because of the length of time it takes to develop and commercialize the products produced using our process technologies, we and our industry partners must make development and production decisions well in advance of

------

<u>[**Table of Contents**](#ib82e114cd19f45afae73e7a64e42f208_1390)</u>

commercial production and sale of such products. Our and our industry partners' ability to accurately forecast demand for any of the products produced using our process technologies that are commercialized can be adversely affected by a number of factors, many of which are outside of our control, including actions by our competitors, changes in market conditions, environmental factors and adverse weather conditions. A shortfall or surplus in the supply of products produced using our process technologies may reduce our revenues, damage our reputation and adversely affect industry partner relationships, which could harm our business, results of operations and financial condition.

***Our success is highly dependent on our ability to maintain and efficiently utilize our technology platform, and to effectively identify potential products for which to develop and commercialize new process technologies, and problems related to our technology platform could harm our business and result in wasted research and development efforts.***

We are highly dependent on our technology platform for the development and commercialization of products and new process technologies. If we experience challenges in our technology platform, such as problems with engineering new microbes, or if we encounter problems interpreting and analyzing data using our process technologies, our business and ability to compete may be harmed and our financial condition negatively affected.

***We may not be successful in identifying new market opportunities and needs and developing our technology platform, or process technologies to produce products to meet those needs, which would limit our prospects and lead to greater dependency on the success of a smaller number of target products.***

The success of our business model depends in part on our ability to identify new market opportunities and needs for our technology platform, or process technologies to produce products to meet those needs. The manufacturing technologies we research and develop are new and continuously changing and advancing. The products that are derived from these technologies may not be applicable or compatible with demands in existing or future markets. Furthermore, we may not be able to identify new opportunities as they arise for products since future applications of any given product may not be readily determinable, and we cannot reasonably estimate the size of any markets that may develop. If we are not able to successfully identify new market opportunities and needs and develop new technologies, processes or products to meet those needs beyond those we currently develop, we may be unable to expand our business and will therefore be highly dependent on the revenues related to the products that can currently be produced using our process technologies.

***Our failure or the failure of our industry partners to realize expected economies of scale could limit our or our partners' ability to sell products produced using our process technologies at competitive prices, negatively impact our ability to enter into other strategic arrangements and the potential for other industry partners to adopt our process technologies, and materially and adversely affect our business and prospects.***

We and our industry partners may be unable to realize expected economies of scale in connection with scale up and commercialization efforts. The failure to achieve these efficiencies or realize these expected benefits could negatively impact our or our industry partners' ability to sell products produced using our process technologies at competitive prices, negatively impact our ability to enter into other strategic arrangements and the potential for other industry partners to adopt our process technologies, and materially and adversely affect our business and prospects.

***Our microbial protein products business, which allows for the extraction of spent microbes that contain protein and other valuable nutrients which can then be used in numerous applications, may not develop as currently expected.***

Microbial protein is composed of spent microbes from LanzaTech commercial facilities. These microbes are comprised of proteins and other valuable nutrients and have performed the task of gas fermentation, have been extracted from the relevant commercial unit and are no longer viable. These materials can be isolated and used in numerous applications, including feed products for livestock and fish, fertilizers for agricultural applications, and protein extract-based products. While we believe many of these markets are large and diverse, with stakeholders actively seeking sustainable and nutritious inputs, we cannot be certain that these markets will materialize or that customers will purchase our protein products in sufficient quantities. With only one commercial customer that is currently selling residual microbial protein as a component in fish and livestock feed products, this business has a

------

<u>[**Table of Contents**](#ib82e114cd19f45afae73e7a64e42f208_1390)</u>

limited commercial history. Our protein products business may not develop to the extent currently expected, which may adversely affect our business and prospects.

***Natural or man-made disasters, social, economic and political instability, and other similar events may significantly disrupt our and our industry partners' businesses, and negatively impact our results of operations and financial condition.***

Our corporate headquarters are located in Skokie, Illinois and we work with industry partners in multiple other locations, including in China, Japan, India, Canada, Australia, Italy, Spain, UK, Netherlands and South Africa. These locations, in particular a number of our current and potential non-U.S. locations, may be subject to social, economic and political instability, such as social uprisings. Any of our or our industry partners' facilities may be harmed or rendered inoperable by natural or man-made disasters, including earthquakes, tornadoes, hurricanes, wildfires, floods, tsunamis, nuclear disasters, acts of terrorism or other criminal activities, the imposition or heightening of sanctions or other economic or military measures in relation to the current Russia-Ukraine conflict, infectious disease outbreaks and power outages, which may render it difficult or impossible for us or our industry partners to operate our businesses for some period of time. Our and our industry partners' facilities would likely be costly to repair or replace, and any such efforts would likely require substantial time. Any disruptions in our or our industry partners' operations could negatively impact our business and results of operations, and harm our reputation. Our or our industry partners' disaster recovery plans may not be sufficient to address an actual disaster, in particular any events that negatively impact our or our industry partners' physical infrastructures. In addition, we and our industry partners may not carry sufficient business insurance to compensate for losses that may occur. Any such losses or damages could have a material adverse effect on our results of operations and financial condition, and success as an overall business.

***Governmental programs designed to incentivize the production and consumption of low-carbon fuels and carbon capture and utilization, may be implemented in a way that does not include products produced using our novel technology platform and process technologies or could be repealed, curtailed or otherwise changed, which would have a material adverse effect on our business, results of operations and financial condition.***

We and other participants in the biomass-based and low-carbon fuel industry rely on governmental programs requiring or incentivizing the production and consumption of fuels with lower carbon intensity than conventional fossil fuels and carbon capture and utilization. Biomass-based and low-carbon fuel has historically been more expensive to produce than petroleum-based fuel and these governmental programs support a market for biomass-based and low-carbon fuel that might not otherwise exist.

One of the most important of these programs is the Renewable Fuel Standard II ("RFS II"), a Federal law which requires that transportation fuels in the United States contain a minimum amount of renewable fuel. This program is administered by the Environmental Protection Agency ("EPA"). The EPA's authority includes setting annual minimum aggregate levels of consumption in four "nested" renewable fuel categories, including categories in which our fuel competes (including advanced biofuel, biomass-based diesel and cellulo biofuel). The parties obligated to comply with this renewable volume obligation ("RVO"), are petroleum refiners and petroleum fuel importers. The petroleum industry is strongly opposed to the RFS II program and can be expected to continue to press for changes both in the RFS II program itself and in the way that it is administered by the EPA. The EPA has not approved LanzaTech-derived ethanol from industrial emissions as a Renewable Identification Number ("RIN") generating fuel (i.e., a fuel that generates credits) under the RFS II program.

The United States Congress could repeal, curtail or otherwise change the RFS II program in a manner adverse to us, such as by excluding products produced using our novel technology platform and process technologies. Similarly, the EPA could curtail or otherwise change its administration of the RFS II program in a manner adverse to us, including by not increasing or even decreasing the RVO, by waiving compliance with the RVO or otherwise. Furthermore, judicial review of the EPA's actions, including any judicial decisions that the EPA failed to adequately evaluate the environmental impacts of RFS II, could create uncertainty in the administration of the RFS II program. In addition, while Congress specified RFS II volume requirements through 2022 (subject to adjustment in the rulemaking process), beginning in 2023 required volumes of renewable fuel will be largely at the discretion of the EPA (in coordination with the Secretary of Energy and Secretary of Agriculture), which must set the volumes after

------

<u>[**Table of Contents**](#ib82e114cd19f45afae73e7a64e42f208_1390)</u>

evaluating a set of particular statutory factors. We cannot predict what changes, if any, will be instituted or the impact of any changes on our business, although adverse changes could seriously harm our business, results of operations and financial condition.

The California Low Carbon Fuel Standard ("LCFS"), is another program that provides a strong incentive for production of renewable diesel and alternative jet fuel, and fuels produced through methods involving carbon capture and utilization. The LCFS could be repealed or amended in a manner that eliminates or reduces this incentive, or could be implemented in a way that excludes or negatively affects products produced using our novel technology platform, such as by assigning a lower carbon intensity to a fuel pathway produced using a competitor's technology.

Additionally, while the efforts of other jurisdictions to mitigate climate change are expected to result in the adoption of similar programs as the RFS II program or LCFS, increasing stakeholder scrutiny of the greenhouse gas ("GHG"), reduction benefits attributable to low-carbon fuels production and consumption could dampen interest in the adoption of similar programs. While the products produced using our process technologies generally compare favorably with conventional low-carbon fuels, public sentiment against reliance upon low-carbon fuels or carbon capture and utilization as pathways to deep decarbonization could adversely affect our market opportunities.

***Any decline in the value of carbon credits or other incentives associated with products produced using our process technologies could harm our results of operations, cash flow and financial condition.***

The value of products produced using our process technologies may be dependent on the value of carbon credits, programs relating to low-carbon materials and products standards and other similar regulatory regimes or the implicit value of decarbonized materials. The value of these credits fluctuates based on market and regulatory forces outside of our control. There is a risk that the supply of low-carbon alternative materials and products outstrips demand, resulting in the value of carbon credits declining. Any such declines could mean that the economic benefits from our industry partners' efforts to de-carbonize their operations might not be realized. Any decline in the value of carbon credits or other incentives associated with products produced using our process technologies could harm our results of operations, cash flow and financial condition. The value of carbon credits and other incentives may also be adversely effected by legislative, agency, or judicial determinations.

***We expect to rely on a limited number of industry partners for a significant portion of our near-term revenue.***

We currently have agreements with a limited number of industry partners, including Suncor, IndianOil Corporation Limited ("IndianOil"), Mitsui, Sekisui Chemical Co., Ltd. ("Sekisui") and the Shougang Joint Venture, from which we expect to generate most of our revenues through the end of 2023. Entities in which the Shougang Joint Venture holds a controlling interest operate the three currently operating commercial scale facilities that produce low carbon ethanol using our process technology. In addition, a commercial scale facility is in advanced stages of construction by our partner ArcelorMittal. The facility is expected to begin commissioning in the coming months. The loss of one or more of our industry partners, a substantial reduction in the scope of their projects, their failure to exercise customer options, their unwillingness to extend contractual deadlines if we are unable to meet production requirements, their inability to perform under their contracts or a significant deterioration in their financial condition could harm our business, results of operations and financial condition. If we fail to perform under the terms of these agreements, the industry partners could seek to terminate these agreements or pursue damages against us, including liquidated damages in certain instances, which could harm our business.

***We and our industry partners are subject to extensive international, national and subnational laws and regulations, and any changes in relevant laws or regulations, or failure to comply with these laws and regulations, could have a material adverse effect on our business and could substantially hinder our and our partners' ability to manufacture and commercialize products produced using our process technologies.***

We and our industry partners are subject to extensive international, national and subnational laws and regulations relating to the production of renewable fuels, the protection of the environment and in support of the

------

<u>[**Table of Contents**](#ib82e114cd19f45afae73e7a64e42f208_1390)</u>

ethanol industry at large. These laws, their regulatory requirements and their implementation and enforcement impact our existing and potential business operations by imposing restrictions on our and our industry partners':

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• existing and proposed business operations or the need to install enhanced or additional controls;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• need to obtain and comply with permits and authorizations;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• liability for exceeding applicable permit limits or legal requirements;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• specifications related to the ethanol and other products we or our industry partners market and produce using our process technologies;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• criteria for assessing the carbon intensity and GHG emissions attributable to fuels produced using our process technologies.

In the normal course of business, we and our industry partners may be involved in administrative or legal proceedings under the Comprehensive Environmental Response, Compensation, and Liability Act of 1980, the Resource Conservation and Recovery Act of 1976 ("RCRA") in the United States, and similar environmental laws across the globe relating to the designation of certain sites for investigation or remediation with respect to environmental risks, the disposal of hazardous waste, and reduction of the hazards associated with storage, handling and transportation of the products we and our industrial partners produce. Potential consequences of these proceedings can include the need to pay for remediation of contaminated sites, the costs of which can be significant and uncertain.

Likewise, in the normal course of business, we and our industry partners may need to obtain and comply with air emissions permits pursuant to the Clean Air Act of 1963 and water discharge permits pursuant to the Clean Water Act of 1972 in the United States, and similar environmental permits and authorizations across the globe relating to air and water emissions. Potential changes to regulatory, permit and authorization standards, requirements or processes may result in uncertainty and additional costs for us and our industry partners.

Furthermore, GHG emissions are subject to environmental laws and regulations in the various jurisdictions in which we and our industry partners have operations. Some of our and our industry partners' operations are within jurisdictions that have or are developing regulatory regimes governing emissions of GHGs, including carbon dioxide ("CO2"). These include existing coverage under the European Union Emission Trading System, the California cap and trade scheme, India's Performance, Achieve and Trade scheme, South Africa's Trade Exposure and Greenhouse Gas Benchmark Regulations, the Tokyo Cap-and-Trade Program, China's Emission Trading Scheme, related subnational programs and any potential expansions of these policies or related policies. In addition, the EPA requires mandatory reporting of GHG emissions and is regulating GHG emissions for new construction and major modifications to existing facilities. The EPA and California also regulate the amount of GHGs that may be emitted by new motor vehicles, including passenger cars, and new commercial airplanes. These and related regulations could be implemented and developed in ways that reduce or eliminate reliance on carbon-based fuels in transportation, for example, by hastening the widespread adoption of electricity or hydrogen as a fuel source, in lieu of low-carbon fuels, for certain categories of transportation vehicles.

Increased public concern surrounding the emission of GHGs may result in more international, national or subnational requirements to reduce or mitigate the effects of GHG emissions. Although uncertain, these developments could increase the costs related to the application of our fermentation technology. Additionally, although governmental policies to reduce GHG emissions may continue to incentivize the production of low-carbon fuels and carbon capture, it is also possible that such policies could be altered in a way that may negatively impact our growth, increase our and our industry partners' operating costs, or reduce demand for our technology. We cannot predict the manner or extent to which such policy or legislation may affect our industry partners and ultimately harm or help our business or the carbon capture industry in general.

Our business could be affected in the future by additional international, national and subnational regulation, pricing of GHG emissions or other climate change legislation, regulation or agreements. It is difficult at this time to estimate the likelihood of passage, or predict the potential impact, of any additional legislation, regulations or

------

<u>[**Table of Contents**](#ib82e114cd19f45afae73e7a64e42f208_1390)</u>

agreements. Potential consequences of new obligations could include increased technology, transportation, material, and administrative costs and may require us to make additional investments in our operations. As we continue distributing our technology to our target markets, international, national or subnational government entities may seek to impose regulations or competitors may seek to influence regulations through lobbying efforts.

Any changes in laws or regulations or failure by us or our industry partners to comply with applicable regulatory laws and regulations could have a material adverse effect on our reputation as well as our business, results of operations and financial condition and could substantially hinder our and our partners' ability to manufacture and commercialize products produced using our process technologies.

***Our success may be dependent on popular, government and corporate sentiment regarding the production of carbon-based fuels and chemicals and the development and deployment of carbon capture and utilization technology.***

At present, we believe that popular, government and corporate sentiment largely favors the production of carbon-based fuels and chemicals and the development and deployment of carbon capture and utilization technology, which has led to many national governments' enactment of policies and incentives that favor the production of the fuels and chemicals we manufacture and the processes we have developed to create them. However, there are a number of scientists, policy makers and other actors who believe carbon capture and utilization technologies will simply prolong the life of high-carbon sectors and impede the transition to renewable energy sources. Such individuals believe that using the carbon capture and utilization process to produce fuels, such as ethanol, simply defers the emission of CO2 into the atmosphere and that anything that promotes the adoption of low-carbon fuels and advanced liquid fuels (other than hydrogen produced via electrolysis) will result in "locking in" a carbon economy from which the world should be moving away. These scientists, policy makers and other actors advocate for the adoption of regulations and incentives that would reduce or eliminate reliance on carbon-based fuels in favor of the adoption of electricity and hydrogen as fuel sources.

If scientists, policy makers and other actors are successful in convincing governments and corporations to enact policies that disfavor, or changes in government administrations result in shifts in policy that disincentivize, the production of carbon-based fuels and the development and deployment of carbon capture and utilization technology, it could negatively impact the demand for products produced using our process technologies and our ability to maintain and develop relationships with our strategic partners, which would harm our business, results of operations and financial condition. The viability of our business model also could be impacted if, over time, popular, government and corporate support gravitates significantly away from the use of carbon-based fuels toward the predominant use of electricity and hydrogen as fuel sources.

***We and our industry partners use hazardous materials and must comply with applicable environmental, health and safety laws and regulations. Any claims relating to improper handling, storage or disposal of these materials or noncompliance with applicable laws and regulations could be time consuming and costly and could adversely affect our business and results of operations.***

We and our industry partners use hazardous chemicals and biological materials and are subject to a variety of international, national and subnational laws and regulations governing the use, generation, manufacture, storage, handling and disposal of these materials, including RCRA and the Occupational Safety and Health Act of 1970. Although we and our industry partners have implemented safety procedures for handling and disposing of these materials and waste products, we cannot be sure that our safety measures are compliant with legal requirements or adequate to eliminate the risk of accidental injury or contamination. In the event of contamination or injury, we could be held liable for any resulting damages, and any liability could exceed our insurance coverage. There can be no assurance that neither we nor any of our industry partners will not violate environmental, health and safety laws as a result of human error, accident, equipment failure or other causes.

Compliance with applicable environmental, health and safety laws and regulations is expensive and time consuming, and the failure to comply with past, present or future laws or regulations could result in the imposition of fines, third-party property damage, product liability and personal injury claims, investigation and remediation costs, the suspension of production or a cessation of operations. Our liability in such an event may exceed our total

------

<u>[**Table of Contents**](#ib82e114cd19f45afae73e7a64e42f208_1390)</u>

assets. Liability under environmental laws can be joint and several and without regard to comparative fault. Environmental laws and regulations could become more stringent over time, imposing greater compliance costs and increasing risks and penalties associated with violations, which could impair our research, development or production efforts and harm our business. Accordingly, violations of present and future environmental laws or regulations by us or any of our industry partners could restrict our ability to develop and commercialize products using our process technologies, build out or expand facilities, or pursue certain technologies, and could require us and our industry partners to acquire equipment or incur potentially significant costs to comply with environmental regulations. In addition, our hazardous materials and environmental laws and regulations-related risks may augment as we expand our international operations, including imposition of laws and regulations impacting our ability to transfer hazardous chemicals and biological materials between countries.

***We may be subject to product liability claims, which could result in material expense, diversion of management time and attention and damage to our business, reputation and brand.***

The products produced using our process technologies that we and our industry partners commercialize may contain undetected defects or impurities that are not discovered until after the products have been used by customers or incorporated into products for end-users. This could result in claims from customers or others, damage to our business and reputation and brand or significant costs to correct the defect or impurity. Therefore, the sale of products produced using our process technologies entails the risk of product liability claims. Any product liability claim brought against us, regardless of its merit, could result in material expense, diversion of management time and attention, damage to our business, reputation and brand and cause us to fail to retain existing industry partners or to fail to attract new industry partners.

***Ethical, legal and social concerns about genetically engineered products and process technologies that use genetically engineered supplies could limit or prevent the use of products produced using our process technologies and could limit our revenues.***

The use of genetically engineered products and process technologies that use genetically engineered supplies is subject to laws and regulations in many countries, including by the EPA under the Toxic Substances Control Act of 1976, some of which are new or still evolving. Public attitudes about the safety and environmental hazards of genetically engineered products and processes, and ethical concerns over genetic research, could influence public acceptance of our technology, processes and products produced using our process technologies that use genetically engineered supplies.

Our ability to develop and commercialize one or more of our technologies or process technologies could be limited by additional factors, including:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• public attitudes regarding, and potential changes to laws governing, ownership of genetic material, which could harm our intellectual property rights with respect to our genetic material and discourage others from supporting, developing or commercializing products produced using our process technologies; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• governmental reaction to negative publicity concerning genetically engineered organisms, which could result in greater government regulation of genetic research, greater government regulation of genetic-related feedstock sources, or other adverse governmental regulatory restrictions.

The subject of genetically engineered organisms has received negative publicity, which has aroused public debate. This adverse publicity could lead to greater regulation and trade restrictions on imports of genetically engineered products. These trends could result in increased expenses, delays or other impediments to our programs or the public acceptance and commercialization of the products produced using our process technologies.

***Our genetically engineered microbes may be subject to regulatory scrutiny and may face future development and regulatory difficulties. Additionally, failure to obtain import permits for all relevant microbes in jurisdictions with our industry partners could adversely affect our business and results of operations.***

Some of our genetically engineered microbes may have significantly altered characteristics compared to those found in the wild and may be subject to regulatory scrutiny. As a result, we may be required to implement additional

------

<u>[**Table of Contents**](#ib82e114cd19f45afae73e7a64e42f208_1390)</u>

costly measures to obtain and maintain our regulatory permits, licenses, authorizations and approvals. To the extent such regulatory scrutiny or changes impact our ability to execute on existing or new programs for our industry partners, or make doing so more costly or difficult, our business, financial condition, or results of operations may be adversely affected.

Because the use of genetically engineered products and process technologies that use genetically engineered supplies is subject to laws and regulations in many countries, some of which are new or still evolving, regulatory requirements, including those related to import permits, may continue to change in various jurisdictions. If such regulatory requirements prevent us from obtaining import permits for jurisdictions where we have industry partners, such changes may impact our ability to execute on existing or new programs for our industry partners, or make doing so more costly or difficult, which may adversely affect our business, financial condition, results of operations, market share and prospects.

***Our government grants are subject to uncertainty, which could harm our business and results of operations.***

We have sought and may continue to seek to obtain government grants in the future to offset a portion of the costs of our research and development, commercialization and other activities. We cannot be certain that we will be able to secure any such government grants in a timely fashion, or at all. Moreover, any of our existing grants or new grants that we may obtain may be terminated, modified or recovered by the granting governmental body. If such grant funding is discontinued, our revenue and cash received from grants will decrease. If we do not receive grants we are counting on, our liquidity will be impacted, which will impact our ability to grow or maintain our business.

We may also be subject to additional regulations and audits by government agencies as part of routine audits of our activities funded by our government grants. As part of an audit, these agencies may review our performance, cost structures and compliance with applicable laws, regulations and standards. Funds available under grants must be applied by us toward the research and development programs specified by the granting agencies, rather than for all of our programs generally. If any of our costs are found to be allocated improperly, the costs may not be reimbursed and any costs already reimbursed may have to be refunded. Accordingly, an audit could result in an adjustment to our revenues and results of operations.

***The requirements of being a public company may strain our resources and divert management's attention, and the increases in legal, accounting and compliance expenses that will result from being a public company may be greater than we anticipate.***

As a result of the Business Combination, we have become a public company, and as such, we have and will continue to incur significant legal, accounting and other expenses that we did not incur as a private company. We are subject to the reporting requirements of the Exchange Act, and we are also required to comply with the applicable requirements of the Sarbanes-Oxley Act and the Dodd-Frank Wall Street Reform and Consumer Protection Act, as well as the rules and regulations subsequently implemented by the SEC and the listing standards of Nasdaq, including changes in corporate governance practices and the establishment and maintenance of effective disclosure and financial controls. Compliance with these rules and regulations can be burdensome. Our management and other personnel have recently devoted and will continue to devote a substantial amount of time to these compliance initiatives. Moreover, these rules and regulations will increase our historical legal and financial compliance costs and will make some activities more time-consuming and costly. For example, these rules and regulations may make it more difficult and more expensive for us to obtain director and officer liability insurance than we obtained as a private company, and could also make it more difficult for us to attract and retain qualified members of the LanzaTech Board as compared to when we were a private company. In particular, we expect to incur significant expenses and devote substantial management effort toward ensuring compliance with the requirements of Section 404 of the Sarbanes-Oxley Act. We are hiring additional accounting and financial staff, and engaging outside consultants, all with appropriate public company experience and technical accounting knowledge and maintaining an internal audit function, which will increase our operating expenses. Moreover, we could incur additional compensation costs in the event that we decide to pay cash compensation closer to that of other public companies, which would increase our general and administrative expenses and could materially and adversely affect our profitability.

------

<u>[**Table of Contents**](#ib82e114cd19f45afae73e7a64e42f208_1390)</u>

***Our management has limited experience in operating a public company.***

Our executive officers and directors have limited experience in the management of a publicly traded company subject to significant regulatory oversight and reporting obligations under federal securities laws. Our management team may not successfully or effectively manage our transition to a public company following the Business Combination. Their limited experience in dealing with the increasingly complex laws pertaining to public companies could be a significant disadvantage in that it is likely that an increasing amount of their time may be devoted to these activities, which will result in less time being devoted to our management and growth. We may not have adequate personnel with the appropriate level of knowledge, experience and training in the accounting policies, practices or internal controls over financial reporting required of public companies in the United States. It is possible that we will be required to expand our employee base and hire additional employees to support our operations as a public company, which will increase our operating costs in future periods.

***If we experience a significant disruption in our information technology systems, including security breaches, or if we fail to implement new systems and software successfully, our business operations and financial condition could be adversely affected.***

We depend on information technology systems to, among other functions, control our manufacturing processes, process orders and invoices, collect and make payments, interact with industry partners and suppliers, manage inventory and otherwise conduct our business. We also depend on these systems to respond to inquiries, contribute to our overall internal control processes, maintain records of our property, plant and equipment and record and pay amounts due to vendors and other creditors. The failure of our information technology systems to perform as we anticipate could disrupt our business and could result in transaction errors, processing inefficiencies and the loss of sales and industry partners. As we implement planned upgrades or changes to systems, we may also experience interruptions in service, loss of data or reduced functionality and other unforeseen material issues which could adversely impact our ability to provide quotes, take orders and otherwise run our business in a timely manner. In addition, if our new systems fail to provide accurate and increased visibility into pricing and cost structures, it may be difficult to improve or maximize our profit margins. As a result, our results of operations could be adversely affected.

In addition, cyber-attacks or security breaches could compromise our trade secrets or other confidential, business critical information, cause a disruption in our operations, or harm our reputation. Our information technology systems are subject to potential disruptions, including significant network or power outages, service disruptions or interruptions from third-party information technology service providers, software or hardware errors, cyberattacks, computer viruses, malware, ransomware events, other malicious codes and/or unauthorized access attempts, denial-of-service attacks, phishing schemes, fraud, or other disruptive problems, any of which, if successful, could result in data leaks or otherwise compromise our confidential or proprietary information and disrupt our operations. Despite our efforts to protect sensitive information and comply with and implement data security measures, there can be no assurance that any controls and procedures that we have in place will be sufficient to protect us. Further, as cyber threats are continually evolving, our controls and procedures may become inadequate and we may be required to devote additional resources to modify or enhance our systems in the future. We may also be required to expend resources to monitor for and remediate cyber-related incidents or to enhance and strengthen our cyber security, including by deployment of additional personnel and technical protection measures, further training of employees, changing vendor control and monitoring practices, and engaging third-party experts and consultants. Any such disruptions to our information technology systems, breaches or compromises of data, or misappropriation of information could result in violation of privacy and other laws, litigation, fines, negative publicity, lost sales or business delays, any of which could have a material adverse effect on our business, financial condition or results of operations.

***International sales by us and our industry partners expose us and our industry partners to the risk of fluctuation in currency exchange rates and rates of foreign inflation, which could adversely affect our results of operations.***

Because we and our industry partners commercialize and sell products produced using our process technologies outside of the United States, a portion of our and our industry partners' revenues is generated outside of the United States and we derive some of our revenues from our industry partners in their local currencies. As a result, our

------

<u>[**Table of Contents**](#ib82e114cd19f45afae73e7a64e42f208_1390)</u>

revenues and results of operations are subject to foreign exchange fluctuations, which we may not be able to manage successfully. We bear the risk that the rate of inflation in the foreign countries where we and our industry partners incur costs and expenses or the decline in value of the U.S. dollar compared to those foreign currencies, will increase our costs as expressed in U.S. dollars. The prices of the products produced using our process technologies may not be adjusted to offset the effects of inflation on our or our industry partners' cost structure, which could increase costs and reduce net operating margins. If we do not successfully manage these risks through hedging or other mechanisms, our revenues and results of operations could be adversely affected.

***Changes in interest rates and capital availability may impact investment and financing decisions by our industry partners, which could adversely affect our results of operations.***

We depend on partnering, licensing, and contractual relationships with our industry partners that implement our process technologies, as well as investments by such partners, as a significant source of financing. Changes in credit and capital market conditions, including changes in interest rates and capital availability, may increase the cost of financing for our industry partners, which may limit their ability or willingness to enter into partnering agreements with us or to further invest in their facilities that implement our process technologies. Such changes may also make it more difficult for us to obtain favorable terms for any future partnership arrangements. To the extent that these changes impact investment and financing decisions by our industry partners in a manner that is adverse to us, such changes could adversely affect our results of operations.

***Any failure by us to manage acquisitions and other significant transactions successfully may have a material adverse effect on our results of operations, financial condition, and cash flows.***

From time to time, we may consider opportunities to acquire other companies, products or technologies that may enhance our capabilities, expand the breadth of our markets or partner base, or advance our business strategies. Potential acquisitions involve numerous risks, including: problems assimilating the acquired service offerings, products or technologies, issues maintaining uniform standards, procedures, quality control and policies, unanticipated costs associated with acquisitions, diversion of management's attention from our existing business, risks associated with entering new markets in which we have limited or no experience, increased legal and accounting costs relating to the acquisitions or compliance with regulatory matters, and unanticipated or undisclosed liabilities of any target.

We have no current commitments with respect to any acquisition. We do not know if we will be able to identify acquisitions we deem suitable, whether we will be able to successfully complete any such acquisitions on favorable terms or at all, or whether we will be able to successfully integrate any acquired service offerings, products or technologies. Our potential inability to manage acquisitions and other significant transactions successfully or to integrate any acquired business, products or technologies effectively may adversely affect our business, results of operations and financial condition.

***We believe our company culture has contributed to our success, and if we cannot maintain this culture as we grow and, in particular, become a public company, our business could be harmed.***

We believe that our culture has contributed to our success to date. We have invested in building a strong corporate culture and believe it is one of our most important and sustainable sources of competitive advantage. Our corporate culture is team-oriented, community-based and rooted in company values to promote close alignment between employees throughout the organization. Community strengthening events and team activities encourage cross-team and cross-location interactions. This foundation promotes an understanding of our organizational values and ensures that our team members stand for and contribute to the vision and objectives of the company. Any failure to maintain our culture could negatively affect our ability to retain and recruit personnel, which is critical to our growth, and to effectively focus on and pursue our corporate objectives. In addition, as we develop the systems and processes associated with being a public company, we may find it difficult to maintain these important aspects of our culture. Furthermore, as we grow and evolve on an international scale, we may find it increasingly difficult to maintain these beneficial aspects of our corporate culture throughout our global footprint. If we fail to maintain our corporate culture, or if we are unable to retain or hire key personnel that contribute positively to our corporate culture, our business and competitive position may be harmed.

***Causes of supply chain challenges, including COVID-19, could result in delays or increased costs for us and our partners deploying our technologies.***

The products that we and our partners produce using our process technologies must be delivered to our industry partners and involve a variety of inputs which must be procured and delivered to our facilities. Our suppliers, sub-contractors and industry partners have been disrupted by certain issues related to the COVID-19 pandemic, including worker absenteeism, quarantines, restrictions on employees' ability to work, office and factory closures, disruptions to ports and other shipping infrastructure, border closures or other travel or health-related restrictions. Supply chain disruptions may also occur from time to time due to a range of factors beyond our control, including, but not limited to, climate change, increased costs of labor, freight costs and raw material prices along with a shortage of qualified workers. Such issues may cause delays in the delivery of, or increases in the cost of, the inputs used in our process technologies, potentially resulting in delays or increased costs for us and our partners deploying our technologies or for our industry partners purchasing our products, which may materially impact our business, financial condition and results of operations.

***We and our industry partners have a limited operating history utilizing our technology and different feedstocks, which may make it difficult to evaluate our future viability and predict our future performance.***

We and our partners have a limited operating history utilizing our process technologies and different feed stocks on which to base an evaluation of our business and prospects. Our operating results are not predictable and our historical results may not be indicative of our future results. Few peer companies with our business model exist and none have yet established long-term track records at scale that might assist us in predicting whether our business model and strategy can be implemented and sustained over an extended period of time. It may be difficult for you to evaluate our potential future performance without the benefit of established long-term track records from companies implementing a similar business model. We may encounter unanticipated problems as we continue to refine our business model and process technologies, and may be forced to make significant changes to our anticipated sales and revenue models to compete with our competitors' offerings, which may adversely affect our results of operations and profitability.

***We have not yet generated material revenues from marketing of CarbonSmart products and our revenue forecast must be considered in light of the uncertainty and risks frequently encountered by companies in their early stage of development.***

We have not yet generated material revenues from marketing CarbonSmart products or the sale of our equipment. We are subject to the risks inherent to early-stage companies seeking to develop, market and distribute new products, particularly companies in evolving markets such as renewable energy and technology. The likelihood of our success must be considered in light of the problems, expenses, difficulties, complications and delays frequently encountered in connection with the development, introduction, marketing and distribution of new products in a competitive environment.

Such risks include dependence on the success and acceptance of our products, the ability to attract and retain a suitable partner base, and the management of growth. To address these risks, we must, among other things, further develop and enhance our process technologies, generate increased demand for our products, attract a sufficient partner base, collaborate with partners, respond to competitive developments, and attract, retain and motivate qualified personnel. We are thus subject to many of the risks common to companies in their early stage of development, including under-capitalization, cash shortages, limitations with respect to personnel, financial, and other resources and lack of revenues.

***Our ability to use our net operating loss carryforwards and certain other tax attributes may be limited.***

We have incurred losses during our history. To the extent that we continue to generate taxable losses, unused losses will carry forward to offset future taxable income, if any, until such unused losses expire, if at all. As of December 31, 2021, we had U.S. federal NOL carryforwards of approximately $236.3 million.

Under the Tax Act (as defined below), as modified by the CARES Act (as defined below), U.S. federal NOL carryforwards generated in taxable periods beginning after December 31, 2017, may be carried forward indefinitely,

------

<u>[**Table of Contents**](#ib82e114cd19f45afae73e7a64e42f208_1390)</u>

but the deductibility of such net operating loss carryforwards in taxable years beginning after December 31, 2020, is limited to 80% of taxable income. It is uncertain if and to what extent various states will conform to the Tax Act or the CARES Act.

In addition, our NOL carryforwards are subject to review and possible adjustment by the IRS, and state tax authorities. Under Sections 382 and 383 of the Code, our federal net operating loss carryforwards and other tax attributes may become subject to an annual limitation in the event of certain cumulative changes in the ownership of our stock. An "ownership change" pursuant to Section 382 of the Code generally occurs if one or more stockholders or groups of stockholders who own at least 5% of a company's stock increase their ownership (as measured by value) by more than 50 percentage points over their lowest ownership percentage within a rolling three-year period. Our ability to utilize our NOL carryforwards and other tax attributes to offset future taxable income or tax liabilities may be limited as a result of ownership changes, including potential changes in connection with our migration from New Zealand to the United States, the Business Combination or other transactions. Similar rules may apply under state tax laws. We have not yet determined the amount of the cumulative change in our ownership resulting from the Business Combination or other transactions, or any resulting limitations on our ability to utilize our net operating loss carryforwards and other tax attributes. If we earn taxable income, such limitations could result in increased future income tax liability to us and our future cash flows could be adversely affected. We have recorded a valuation allowance related to our NOL carryforwards and other deferred tax assets due to the uncertainty of the ultimate realization of the future benefits of those assets.

***Changes in U.S. and foreign tax laws could have a material adverse effect on our business, cash flow, results of operations or financial conditions.***

The tax regimes we are subject to or operate under, including income and non-income taxes, are unsettled and may be subject to significant change. Changes in tax laws, regulations, or rulings, or changes in interpretations of existing laws and regulations, could materially affect our financial position and results of operations. For example, the 2017 Tax Cuts and Jobs Act, or Tax Act, made broad and complex changes to the U.S. tax code, including changes to U.S. federal tax rates, additional limitations on the deductibility of interest, both positive and negative changes to the utilization of future NOL carryforwards, and allowing for the expensing of certain capital expenditures. The Coronavirus Aid, Relief, and Economic Security Act, or CARES Act, has already modified certain provisions of the Tax Act and the United States Congress is considering new proposed tax legislation. The exact impact of the Tax Act and the CARES Act for future years is difficult to quantify, but these changes could materially affect our effective tax rate in future periods, in addition to any changes made by new tax legislation.

The Organization for Economic Cooperation and Development has been working on a Base Erosion and Profit Shifting Project and is expected to continue to issue guidelines and proposals that may change various aspects of the existing framework under which our tax obligations are determined in many of the countries in which we do business. Similarly, the European Commission and several countries have issued proposals that would change various aspects of the current tax framework under which we are taxed. These proposals include changes to the existing framework to calculate income tax, as well as proposals to change or impose new types of non-income taxes, including taxes based on a percentage of revenue.

As we expand the scale of our international business activities, these types of changes to the taxation of our activities could increase our worldwide effective tax rate, increase the amount of taxes imposed on our business, and harm our financial position. Such changes may also apply retroactively to our historical operations and result in taxes greater than the amounts estimated and recorded in our financial statements.

***Political and economic uncertainty, including changes in policies of the Chinese government or in relations between China and the United States, may impact our revenue and materially and adversely affect our business, financial condition, and results of operations.***

We and our partners operate facilities and do business on an international scale, including in China. Political and economic uncertainty, including changes in policies of the Chinese government or relations between China and the United States, may impact us adversely. There is significant uncertainty about the future relationship between China and the United States with respect to trade policy, government relations and treaties. Political uncertainty

------

<u>[**Table of Contents**](#ib82e114cd19f45afae73e7a64e42f208_1390)</u>

surrounding Chinese government policies, international trade disputes between China and the United States, and protectionist measures could result in increased trade controls and regulations. Heightened tensions resulting in restrictions and additional regulations may negatively impact our ability to send our microbes and other supplies to our plants in China, to purchase and ship ethanol out of China, or to gain ethanol-related licenses in China.

The implementation of sanctions on certain Chinese individuals or entities may result in complications for our interactions with LanzaTech China Limited, the Shougang Joint Venture and our joint venture partners in China, or with certain of our strategic investors located in China, including Sinopec. Sinopec is a Chinese investment platform that was jointly established in 2018 by China Petrochemical Corporation ("Sinopec Group") and China Petroleum & Chemical Corporation ("Sinopec Corp"). Sinopec Corp is a majority-owned subsidiary of Sinopec Group, which is controlled by the State-owned Assets Supervision and Administration Commission of the State Council of the People's Republic of China. Based on publicly available information provided by China Petroleum & Chemical Corporation, as of August 2022, the China Petroleum & Chemical Corporation holds, directly or indirectly, 49% of the equity/voting rights of Sinopec. As a result of potential trade and investment restrictions, we may be unable to complete an investment in any joint venture that we may enter into with Sinopec, or to protect our interests in our existing or potential future joint ventures by nominating a non-Chinese director to the board of directors of any such joint venture. Sanctions also may negatively impact our ability to repatriate dividends from a Chinese joint venture and may result in further costs or delays as a result of currency controls. These increased costs and restrictions may reduce our margins or reduce demand for our products if prices increase for our industry partners, and could adversely affect our business, financial condition, and results of operations.

***Our ability or the ability of our partners to operate in China may be impaired by changes in Chinese laws and regulations, including those relating to taxation, environmental regulation, restrictions on foreign investment, and other matters, which can change quickly with little advance notice.***

While we are headquartered in Skokie, Illinois, we have business operations in China. This includes a minority ownership stake in the Shougang Joint Venture, several strategic investors located in China, including Sinopec, and a core team of technical, business and administrative professionals at a LanzaTech office in Shanghai, which support the ongoing operations and further growth of the business in China. We license our technology in China to the Shougang Joint Venture. Entities in which the Shougang Joint Venture holds a controlling interest currently produce low carbon ethanol at three commercial scale facilities using our process technology, which, in addition to its use as fuel, is transported and processed for use in consumer products.

The Chinese government has exercised and continues to exercise substantial control over every sector of the Chinese economy through regulation and state ownership. The central Chinese government or local governments having jurisdiction within China may impose new, stricter regulations, or interpretations of existing regulations, that would require additional expenditures and efforts on our part to ensure our compliance with such regulations or interpretations. For example, regulations in the PRC applicable to LanzaTech China Limited, a WFOE, may change. As such, our operations and the operations of our joint venture partners and our sales and licenses to partners located in China may be subject to governmental and regulatory interference in the provinces in which they operate. We, our joint venture and other partners could also be subject to regulation by various political and regulatory entities, including local and municipal agencies and other governmental subdivisions. Regulations may be imposed or change quickly with little advance notice. Our ability, and the ability of our joint venture and other partners, to operate in China may be impaired by any such laws or regulations, or any changes in laws and regulations in China. We and our joint venture and other partners may incur increased costs necessary to comply with existing and future laws and regulations or penalties for any failure to comply.

***Our operations and financial results may be impacted if the PRC government determines that the contractual arrangements constituting part of the Shougang Joint Venture VIE structure do not comply with PRC regulations, or if these regulations change or are interpreted differently in the future.***

We have business operations in China, several strategic investors located in China, including Sinopec, and a core team of technical, business and administrative professionals at a LanzaTech office in Shanghai, which support the ongoing operations and further growth of the business in China. We also hold a minority ownership stake in the Shougang Joint Venture. We have determined the Shougang Joint Venture to be a VIE for which we are not the

------

<u>[**Table of Contents**](#ib82e114cd19f45afae73e7a64e42f208_1390)</u>

primary beneficiary. The VIE structure was implemented in order to effectuate the intellectual property licensing arrangement between us and the Shougang Joint Venture and is not used to provide investors with exposure to foreign investment in China-based companies where Chinese law prohibits direct foreign investment in the operating companies. If the PRC government determines that the contractual arrangements constituting part of the VIE structure do not comply with PRC regulations, or if these regulations change or are interpreted differently in the future, it could result in a material change to our operations. This could result in our inability to assert contractual control over our intellectual property and other assets in the Shougang Joint Venture, or cause a material change in the value of the shares of the common stock.

***We and our partners may be subject to regulatory actions by the Chinese government targeting concerns related to data security and monopolistic behavior.***

Recent statements and regulatory actions by the Chinese government have targeted companies whose operations involves cross-border data security or anti-monopoly concerns. Although we are incorporated and headquartered in the United States, we may still be subject to certain PRC laws due to our business operations in China. These operations include several strategic investors located in China, including Sinopec, a core team of technical, business and administrative professionals at our office in Shanghai, and our minority ownership stake in, and contractual commitments with, the Shougang Joint Venture.

On June 10, 2021, China promulgated the PRC Data Security Law (the "DSL"), which became effective on September 1, 2021. The DSL intends to regulate data processing activities, ensure data security, promote data development and utilization, protect the data-related rights and interests of individuals and organizations, and safeguard Chinese sovereignty, security and development interests. Article 36 of the DSL provides that any Chinese entity that provides data to foreign judicial or law enforcement agencies (regardless of whether directly or through a foreign entity) without approval from a Chinese authority would likely be deemed to be in violation of the DSL. In addition, pursuant to Article 2 of Measures for Cybersecurity Reviews (the "Measures") issued by the CAC, the procurement of any network product or service by an operator of critical information infrastructure that affects or may affect national security will be subjected to a cybersecurity review. Pursuant to Article 35 of Cybersecurity Law of the PRC, "critical information infrastructure operators" that purchase network products and services which may influence national security will be subject to cybersecurity review by the CAC. With respect to LanzaTech China Limited, the Shougang Joint Venture and our operational partners in China, the exact scope of the term "critical information infrastructure operator" remains unclear, so there can be no assurance that we, the Shougang Joint Venture or our partners will not be subjected to critical information infrastructure operator review in the future. Furthermore, in the event that we, the Shougang Joint Venture or our partners become operators of critical information infrastructure in the future, they may be subject to the DSL, the Measures and cybersecurity review by the CAC.

Article 3 of Anti-Monopoly Law of the PRC (the "Anti-Monopoly Law") prohibits "monopolistic practices," which include: (a) the conclusion of monopoly agreements between operators; (b) the abuse of dominant market position by operators; and (c) concentration of undertakings which has or may have the effect of eliminating or restricting market competition. Furthermore, according to Article 19 of the Anti-Monopoly Law, the operator will be assumed to have a dominant market position if the following apply: (a) an operator has 50% or higher market share in a relevant market; (b) two operators have 66% or higher market share in a relevant market; or (c) three operators have 75% or higher market share in a relevant market. We believe that neither we nor any of our partners in China have engaged in any monopolistic practices in China, and that recent statements and regulatory actions by the Chinese government do not impact our ability to conduct business, accept foreign investments, or list on a U.S. or other foreign stock exchange. However, there can be no assurance that regulators in China will not promulgate new laws and regulations or adopt new series of interpretations or regulatory actions which may require us and our partners to satisfy new requirements related to these concerns.

***Changes in China's economic, political or social conditions or legal system or government policies could have a material adverse effect on our business and operations.***

Our business operations in China include the Shougang Joint Venture, several strategic investors located in China, including Sinopec, and a core team of technical, business and administrative professionals at a LanzaTech

------

<u>[**Table of Contents**](#ib82e114cd19f45afae73e7a64e42f208_1390)</u>

office in Shanghai, which support the ongoing operations and further growth of the business in China. We license our technology in China to the Shougang Joint Venture. Entities in which the Shougang Joint Venture holds a controlling interest currently produce low carbon ethanol at three commercial scale facilities using our process technology, which, in addition to its use as fuel, is transported and processed for use in consumer products. Meanwhile, several additional facilities are being engineered and constructed. Accordingly, our business, financial condition, results of operations and prospects may be influenced to a significant degree by political, economic and social conditions in China generally and by the significant discretion of Chinese governmental authorities. The Chinese government continues to play a significant role in regulating industry development by imposing industrial policies. The Chinese government also exercises significant control over China's economic growth through allocating resources, controlling payment of foreign currency-denominated obligations, setting monetary policy, and providing preferential treatment to particular industries or companies. The increased global focus on environmental and social issues and China's potential adoption of more stringent standards in these areas may adversely impact us or our suppliers.

Furthermore, the Chinese legal system is based in part on government policies and internal rules, some of which are not published on a timely basis or at all and may have a retroactive effect. As a result, we or our suppliers may not be aware of our violation of any of these policies and rules until sometime after the alleged violation. In addition, any administrative and court proceedings in China may be protracted, resulting in substantial costs and diversion of resources and management attention. Further, such evolving laws and regulations and the inconsistent enforcement thereof could also lead to failure to obtain or maintain licenses and permits to do business in China, which would adversely affect us or our suppliers in China. Any such disruption, or if one or more of our Chinese suppliers was prevented from operating, could have an adverse impact on our results of operations and financial condition.

***We may be subject to risks that the Chinese government may intervene or influence our operations at any time.***

Because we have employees located in China and conduct some operations in China, including through our China-based joint venture and at the facilities in China operated by entities in which the Shougang Joint Venture holds a controlling interest using our process technology, we are subject to the risk that the Chinese government may intervene or influence our operations at any time. However, because our operations in China are largely limited to technology licenses and the production of our low carbon ethanol, we do not expect that such intervention or influence would result in a material change in our operations. Nonetheless, in the event that the Chinese government were to intervene in our operations, we might experience a disruption at the three facilities in China operated by entities in which the Shougang Joint Venture holds a controlling interest using our process technology, or at the facilities in construction, to our joint venture and joint venture partners, to our licenses to partners in China and to our low carbon ethanol production, which could have a material adverse effect on our results of operations.

***Products produced by our process technologies compete with or are intended to displace comparable products produced using fossil resources. The market prices for these alternatively produced products and commodities are subject to volatility and there is a limited referenceable market for the more sustainable, waste-based products that our process technologies enable.***

Products produced by our process technologies compete with or are intended to displace comparable products produced using fossil resources. The market prices for these alternatively produced products and commodities are subject to volatility and may depend on uncertain consumer demand as well as changing supply of feedstocks. In particular, demand for our products may depend on changing attitudes toward, and the price and availability of, fossil resources.

We do not believe we have any direct competitors that produce products with similar attributes to ours. Due to the limited competition we face, there is a limited referenceable market for the more sustainable, waste-based products that our process technologies enable. It may be difficult to evaluate our potential future performance without the benefit of established long-term track records from companies developing similar sustainable, waste-based products.

------

<u>[**Table of Contents**](#ib82e114cd19f45afae73e7a64e42f208_1390)</u>

***Process performance at LanzaTech plants is dependent on the quality and quantity of the feedstock supplied from the host facility.***

We design the parameters to best process the feedstock we expect to receive from the host facility. Although we rigorously test feedgas when a project is being designed in order to determine the expected composition of the feedstock there is no guarantee that the quality and quantity of the feedstock will be identical to the test conditions. Feedstock changes based on day-to-day variability in host company process conditions can be anticipated to some extent, but cannot be fully mitigated.

We have experienced variability in the quality and quantity of feedstock supplied from our operating facilities, and although it is typically in the facilities' best interest to provide consistent and good quality feedstock, which help maintain the high utilization of our process, there is no guarantee that it will be supplied.

***The deployment of the technology for alternative waste gas feedstocks can lead to unforeseen issues due to the change in the upstream industrial process.***

While we have designed our reactor and process to minimize the amount of mechanical and operational adjustments required for the utilization of different waste gas feedstocks, there is no guarantee that performance will be as expected. Our microbe has proven to be flexible to different feed gas compositions, with tests conducted at pilot-scale using a wide range of CO2, hydrogen ("H2") and carbon monoxide ("CO")-containing gases.

Scale-up and commercialization of process technologies for alternative feedstocks without first conducting tests at demonstration scale can introduce some risk. Performance related improvements may not be as fungible as anticipated in scaling up alternative feedstocks.

**Risks Related to Our Intellectual Property**

***Our patent rights may not provide commercially meaningful protection against competition, and we may be unable to detect infringement of our patents.***

Our success depends, in part, on our ability to obtain and maintain patent protection and other intellectual property rights to protect our technology from competition. We have adopted a strategy of seeking patents and patent licenses in the United States and in certain foreign countries with respect to certain technologies used in, or relating to, our process technology for developing products. As of December 31, 2022, our overall owned and in-licensed patent portfolio included 1,264 granted patents and 588 pending patent applications across 141 patent families in the United States and in various foreign jurisdictions.

The strength of patents involves complex legal and scientific questions and can be uncertain. The patent applications that we own or license may fail to result in issued patents in the United States or in other foreign countries. Even with regard to the patents that have been issued to us, it is possible that third parties could challenge the validity, enforceability, ownership or scope thereof, which could result in such patents being narrowed, invalidated or held unenforceable. There is a substantial amount of litigation involving patent and other intellectual property rights, including interference and reexamination proceedings before the U.S. Patent and Trademark Office, or oppositions or comparable proceedings in foreign jurisdictions. Furthermore, even if they are unchallenged, our patents and patent applications may not adequately protect our technology or prevent others from designing around our patent claims. In addition, patent laws may change over time, and such changes may impair our ability to maintain, protect or enforce our patents. Moreover, we may not be able to detect unauthorized use of, or take appropriate steps to enforce, our patents rights against third parties. For example, third parties could practice our inventions without authorization, in secret and in territories where we do not have patent protection. Furthermore, despite our efforts and precautions, we may be unable to prevent a third party from copying or otherwise obtaining and using our inventions or other proprietary information or technology without authorization, or from infringing our patents. Such third parties may then try to sell or import products made using our inventions in and into the United States or other territories. We may be unable to prove that such products were made using our inventions, and any legal and contractual remedies available to us may not adequately compensate us.

------

<u>[**Table of Contents**](#ib82e114cd19f45afae73e7a64e42f208_1390)</u>

Additional uncertainty may result from patent reform legislation proposed by the U.S. Congress and other national governments and from legal precedent handed down by the U.S. Court of Appeals for the Federal Circuit, the U.S. Supreme Court and the courts of foreign countries, as they determine legal issues concerning the scope, validity and construction of patent claims. Because patent applications in the United States and many foreign jurisdictions are typically not published until 18 months after filing, or in some cases not at all, and because publication of discoveries in the scientific literature often lags behind the actual discoveries, there is additional uncertainty as to validity of any issued patent. Accordingly, we cannot be certain that any of our patent applications will result in issued patents, or even if issued, be sure of their validity or enforceability. Additionally we cannot predict whether any of our patent rights will be broad enough in scope to provide commercial advantage and prevent circumvention. Also, it may be difficult for us to trace chemicals imported into the United States that are produced by others using microorganisms or processes covered by our patents without our authorization, which will limit our ability to enforce our patent rights against potential infringers. In any event, patents are enforceable only for a limited term.

***Differences and uncertainties with respect to legal systems outside the United States could adversely affect the legal protection available to us.***

We have and plan to continue partnering with others in building manufacturing facilities using our process technologies in countries other than the United States. However, the laws of some foreign countries do not protect intellectual property rights to the same extent as federal and state laws in the United States. Many companies have encountered significant problems, including delays, in protecting and enforcing intellectual property rights in certain foreign jurisdictions. The legal systems of certain countries, particularly certain developing countries, do not favor the enforcement of patents and other intellectual property protection, particularly those relating to bio-industrial technologies. This could make it difficult for us to stop the misappropriation of our trade secrets or the infringement of our patents or other intellectual property rights. Proceedings to enforce our patents and other proprietary rights in foreign jurisdictions could result in substantial costs and divert our efforts and attention from other aspects of our business. Such proceedings could also be met with defenses, counterclaims and countersuits attacking the validity, enforceability, ownership and scope of our intellectual property rights, and if such defenses, counterclaims or countersuits are successful, we could lose valuable intellectual property rights in certain jurisdictions. Accordingly, our efforts to enforce our intellectual property rights in such countries could be inadequate to obtain a significant commercial advantage from the intellectual property that we develop. Moreover, the registration of intellectual property is costly and subject to complex rules, regulations and local laws. Outside the United States, we only file our patent applications in selected foreign jurisdictions and therefore will have no patent protection against potential infringers in jurisdictions where we have not applied for patent protection.

***We may not be able to operate our business without infringing the proprietary rights of third parties.***

Our ability and the ability of our partners to commercialize the products produced using our technology platform depends on the ability to develop, manufacture, market and sell such products without infringing the proprietary rights of third parties. Numerous U.S. and foreign patents and pending patent applications owned by third parties, including parties with whom we may compete, exist in fields including processes that relate to our technology platform and the processes derived using our technology platform. These third parties may allege that our technology platform or the processes derived using our technology platform, or even the methods and organisms themselves, infringe their intellectual property rights, and we may be subject to legal proceedings relating to these claims.

If we are found to infringe the intellectual property rights of a third party, we or our partners could be prohibited from commercializing the product produced using the infringing technology, or from licensing our technology, unless we obtain a license to use the technology covered by the third-party intellectual property rights or are able to design around the relevant third party intellectual property rights. We may be unable to obtain a license on terms acceptable to us, if at all, and we may not be able to redesign our technology or processes to avoid infringement. Even if we are able to redesign technology or processes to avoid an infringement claim, our efforts to design around the third-party intellectual property rights may lead to a less effective or more costly product. In addition, we may be subject to legal proceedings alleging the infringement, misappropriation or other violation of the intellectual property of third parties, which could result in substantial costs and divert our efforts and attention from other

------

<u>[**Table of Contents**](#ib82e114cd19f45afae73e7a64e42f208_1390)</u>

aspects of our business. A court could also order us to pay compensatory damages for any infringement, plus prejudgment interest and could, in addition, treble the compensatory damages and award attorney fees. These damages could be substantial and could harm our reputation, business, financial condition and results of operations. A court also could enter orders that temporarily, preliminarily or permanently prohibit us and our partners from making, using, selling or offering to sell one or more of the products that may be produced using our technology platform and processes, or could enter an order mandating that we undertake certain remedial activities.

***Trade secrets can be difficult to protect and enforce, and our inability to do so could adversely affect our competitive position.***

We rely on trade secrets and confidentiality agreements to protect some of our technology and proprietary know-how that is not patentable, processes for which patents are difficult to enforce, and any other elements of our technology platform that involve proprietary know-how, information or technology that is not covered by patents, particularly where we do not believe patent protection is appropriate or obtainable. However, trade secrets are difficult to maintain and protect. Our strategy for scale-up of production requires us to share confidential information with our business partners and other parties. Our business partners' employees, consultants, contractors or scientific and other advisors may unintentionally or willfully disclose our proprietary information to competitors. Enforcement of claims that a third party has illegally obtained and is using trade secrets is an expensive, time-consuming and uncertain process. In addition, foreign courts are sometimes less willing than U.S. courts to protect trade secrets. If our competitors independently develop equivalent knowledge, methods and know-how, we would not be able to assert our trade secrets against them. Our failure to obtain or maintain trade secret protection could adversely affect our competitive business position.

We have taken measures to protect our trade secrets and proprietary information, but these measures may not be effective. We require new employees and consultants to execute confidentiality agreements upon the commencement of an employment or consulting arrangement with us. These agreements generally require that all confidential information developed by the individual or made known to the individual by us during the course of the individual's relationship with us be kept confidential and not disclosed to third parties. Nevertheless, our proprietary information may be disclosed, third parties could reverse engineer our systems, and others may independently develop substantially equivalent proprietary information and techniques or otherwise gain access to our trade secrets. Costly and time-consuming litigation could be necessary to enforce and determine the scope of our proprietary rights, and failure to obtain or maintain trade secret protection could adversely affect our competitive business position.

***If trade secrets are stolen, misappropriated or reverse engineered, others could use these designs to produce competing products.***

A number of third parties, including various industry partners, plant operators, university scientists and researchers, and those involved in the shipping and handling of products produced using our technology platform, have or may have access in the future to our proprietary technology. If the proprietary technology covered by our trade secrets were stolen, misappropriated or reverse engineered based on unauthorized use or based on extrapolation from our disclosures in our patent applications, it could be used by other parties for their own commercial gain. If this were to occur, it could be difficult, time consuming and costly for us to discover or challenge this type of use, especially in countries with limited intellectual property protection.

***If we are unable to prevent third parties from adopting, registering or using trademarks or otherwise violating our trademark rights, our business could be materially adversely affected.***

We currently hold issued trademark registrations and have trademark applications pending, any of which may be the subject of a governmental or third-party objection, which could prevent the issuance or maintenance of the same and thus create the potential need to rebrand or relabel one or more of our services. As our business matures, our reliance on our trademarks to differentiate us from our competitors increases and as a result, if we are unable to prevent third parties from adopting, registering or using trademarks, trade dress, or other source indicators that infringe, dilute or otherwise violate our trademark rights, our business could be materially adversely affected.

***We may not retain exclusive rights to intellectual property created as a result of our strategic partnering arrangements which could limit our prospects and result in costly and time-consuming disputes.***

We are a party to joint development agreements with a number of parties and are seeking to enter into agreements with others, each of which involve research and development efforts. We expect to enter into additional strategic partnering arrangements in the future. Under our existing agreements, we share, and would share, to various degrees, intellectual property we jointly develop. Any disputes as to ownership with a partner that may arise could encumber or prevent our use of the disputed technology, could harm our relationship with the relevant partner and would likely negatively affect our commercialization plans with respect to that technology. Additionally, litigation may be necessary to resolve disputes as to the ownership of intellectual property rights as between us and our industry partners, which can be costly, distracting to management and can harm our reputation and the value of our company. Further, we may not be successful in defending our intellectual property rights in any such litigation, and if we are unsuccessful, the value of our company could be seriously harmed.

***Some of our intellectual property may be subject to federal regulation such as "march-in" rights, reporting requirements and a preference for U.S. industry, and any such regulations could negatively impact our business and prospects.***

Some of the intellectual property that protects our technology platform has been funded by grants from U.S. government agencies and is subject to certain federal regulations. For example, under the "march-in" provisions of the Bayh-Dole Act, the government may have the right under limited circumstances to require us to grant exclusive, partially exclusive or non-exclusive rights to third parties under any intellectual property discovered through the government-funded programs. March-in rights can be triggered if the government determines that we have failed to work sufficiently towards achieving practical application of a technology or if action is necessary to alleviate health or safety needs, to meet requirements for public use specified by federal regulations or to give preference to U.S. industry. Specifically, certain of our granted and pending patents that cover recombinant and other microorganisms, cell-free protein synthesis platforms, protein expression vectors, fermentative production pathways, and microbial and ethanol conversion pathways may be subject to march-in-rights. These patents account for less than one percent of our granted and pending patents. We are also subject to certain reporting requirements as well as a preference for U.S. industry relating to manufacturing of products under the Bayh-Dole Act. Any such regulations could negatively impact our business and prospects.

***We depend on certain technologies that are licensed to us. We do not control these technologies and any loss of our rights to them could prevent us from developing or selling our process technologies.***

We rely on licenses in order to be able to use various proprietary technologies that are material to our business, including a license with the Battelle Memorial Institute ("Battelle"). We do not own the patents that underlie these licenses. Our rights to use the technology we license are subject to the continuation of and compliance with the terms of those licenses. We do not always control the prosecution, maintenance or filing of the patents to which we hold licenses. Thus, some of these patents and patent applications were not written by us or our attorneys, and we did not have control over their drafting and prosecution. Our licensors might not have given the same attention to the drafting and prosecution of these patents and applications as we would have if we had been the owners of the patents and applications and had control over the drafting and prosecution. We cannot be certain that drafting or prosecution of the licensed patents and patent applications by the licensors have been or will be conducted in compliance with applicable laws and regulations or will result in valid and enforceable patents and other intellectual property rights.

Our rights to use the technology we license are subject to the validity of the owners' intellectual property rights. Enforcement of our licensed patents or defense or any claims asserting the invalidity of these patents is often subject to the control or cooperation of our licensors and/or interpretation of the license agreements. We cannot be certain that we will have control of the enforcement of these patents against third parties. Legal action could be initiated against the owners of the intellectual property that we license. Even if we are not a party to these legal actions, an adverse outcome could harm our business because it might prevent our licensors from continuing to license the intellectual property that we may need to operate our business.

------

<u>[**Table of Contents**](#ib82e114cd19f45afae73e7a64e42f208_1390)</u>

Certain of our licenses contain provisions that allow the licensor to terminate the license upon specific conditions, including breach or insolvency. Our rights under the licenses are subject to our continued compliance with the terms of the license, including the payment of royalties due under the license. Termination of these licenses could prevent us from developing or marketing some or all of our process technologies. Because of the complexity of our technologies underlying our process technologies and the patents we have licensed, determining the scope of the license and related royalty obligation can be difficult and can lead to disputes between us and the licensor. An unfavorable resolution of such a dispute could lead to an increase in the royalties payable pursuant to the license. If a licensor believed we were not paying the royalties due under the license or were otherwise not in compliance with the terms of the license, the licensor might attempt to revoke the license. If such an attempt were successful, we might be barred from developing and selling some or all of our process technologies.

***Any strategic partnering arrangement that involves the licensing of any of our intellectual property may increase our risks, harm our competitive position and increase our costs.***

In addition to partnering with industry leaders through our co-development model, we may enter into licensing arrangements aimed to accelerate commercialization of our production process pipeline. Licensing any of our intellectual property increases the number of people who have access to some of our proprietary information. The scope of any such license may not be sufficiently narrow to adequately protect our interests. Moreover, contractual obligations of our licensees not to disclose or misuse our intellectual property may not be sufficient to prevent such disclosure or misuse. The costs of enforcing contractual rights could substantially increase our operating costs and may not be cost-effective, reasonable under the circumstances or ultimately succeed in protecting our proprietary rights. If our competitors access our intellectual property, they may gain further insight into the technology and design of our process technologies, which would harm our competitive position.

***We may be involved in lawsuits to protect or enforce our patents or the patents of our licensors, or lawsuits asserted by a third party, which could be expensive, time consuming and unsuccessful.***

Competitors may infringe our patents or the patents of our licensors. To counter infringement or unauthorized use, we may need to file infringement claims, which can be expensive and time-consuming. In addition, in an infringement proceeding, a court may decide that a patent of ours or our licensors is not valid or is unenforceable, or may refuse to stop the other party from using the technology at issue on the grounds that our patents do not cover the technology in question. An adverse result in any litigation or defense proceedings could put one or more of our patents at risk of being invalidated or interpreted narrowly and could put our patent applications at risk of not issuing.

Interference proceedings provoked by third parties or brought by the U.S. Patent and Trademark Office may be necessary to determine the priority of inventions with respect to our patents or patent applications or those of our collaborators or licensors. An unfavorable outcome could require us to cease using the related technology or to attempt to license rights to it from the prevailing party. Our business could be harmed if the prevailing party does not offer us a license on commercially reasonable terms. Litigation or interference proceedings may fail and, even if successful, may result in substantial costs and distract our management and other employees. We may not be able to prevent, alone or with our licensors, misappropriation of our proprietary rights, particularly in countries where the laws may not protect those rights as fully as in the United States.

Furthermore, because of the substantial amount of discovery required in connection with intellectual property litigation, there is a risk that some of our confidential information could be compromised by disclosure during this type of litigation. In addition, there could be public announcements of the results of hearings, motions or other interim proceedings or developments.

Because of the uncertainties involved in the issuance and enforcement of patents, and the value of a patent, patent disputes and litigations are common. We may become involved in patent disputes relating to infringement of our technology, with third-parties asserting their patents, with our licensors or licensees, with industry partners and with employees, among others. Patent disputes can take years to resolve, can be very costly and can result in loss of rights, injunctions and substantial penalties. Moreover, patent disputes and related proceedings can distract management's attention and interfere with running the business.

**Risks Related to Ownership of Our Securities**

***The price of the common stock may be volatile.***

Following the Business Combination, fluctuations in the price of New LanzaTech's securities could contribute to the loss of all or part of your investment. Prior to the Business Combination, there was not a public market for the stock of LanzaTech and trading in the shares of AMCI's common stock was not active. If an active market for our securities develops and continues, the trading price of New LanzaTech securities following the Business Combination could be volatile and subject to wide fluctuations in response to various factors, some of which are beyond our control. Any of the factors listed below could have a material adverse effect on your investment in our securities and New LanzaTech securities may trade at prices significantly below the price you paid for them. In such circumstances, the trading price of our securities may not recover and may experience a further decline. Factors affecting the trading price of New LanzaTech's securities may include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• actual or anticipated fluctuations in our quarterly financial results or the quarterly financial results of companies perceived to be similar to us;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• changes in the market's expectations about New LanzaTech's operating results;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the development of new plants;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• success of competitors;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• operating results failing to meet the expectations of securities analysts or investors in a particular period;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• entering into new agreements with partners;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• changes in financial estimates and recommendations by securities analysts concerning New LanzaTech or the industry in which New LanzaTech operates in general;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• operating and stock price performance of other companies that investors deem comparable to New LanzaTech;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• ability to market new and enhanced products and services on a timely basis;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• changes in laws and regulations affecting our business;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• commencement of, or involvement in, litigation involving New LanzaTech;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• changes in New LanzaTech's capital structure, such as future issuances of securities or the incurrence of additional debt;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the volume of shares of common stock available for public sale;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any major change in New LanzaTech's board or management;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• sales of substantial amounts of common stock by our or New LanzaTech's directors, executive officers or significant stockholders or the perception that such sales could occur; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• general economic and political conditions such as recessions, interest rates, fuel prices, international currency fluctuations and acts of war or terrorism.

Broad market and industry factors may materially harm the market price of our securities irrespective of our operating performance. The stock market in general, and Nasdaq specifically, have experienced extreme volatility that has often been unrelated to the operating performance of particular companies. As a result of this volatility, you may not be able to sell your securities at or above the price at which it was acquired. A loss of investor confidence in the market for the stocks of other companies which investors perceive to be similar to New LanzaTech could depress our stock price regardless of our business, prospects, financial conditions or results of operations. A decline in the

------

<u>[**Table of Contents**](#ib82e114cd19f45afae73e7a64e42f208_1390)</u>

market price of our securities also could adversely affect our ability to issue additional securities and our ability to obtain additional financing in the future.

Moreover, the common stock and the common stock issuable upon exercise of the resale securities described in this prospectus represent a substantial percentage of the total outstanding shares of our common stock as of the date of this prospectus. Additionally, if all of the Convertible Securities were converted, the selling stockholders would own 198,818,523 shares of common stock, representing approximately 92.3% of the total outstanding common stock. So long as the registration statement of which this prospectus forms a part is effective, the sales of the securities being offered in this prospectus could result in a significant decline in the public trading price of the common stock.

***Reports published by analysts, including projections in those reports that differ from our actual results, could adversely affect the price and trading volume of the common stock.***

We expect that securities research analysts will establish and publish their own periodic projections for the business of LanzaTech. These projections may vary widely and may not accurately predict the results we actually achieve. Our stock price may decline if our actual results do not match the projections of these securities research analysts. Similarly, if one or more of the analysts who write reports on LanzaTech downgrades our stock or publishes inaccurate or unfavorable research about our business, our stock price could decline. If one or more of these analysts ceases coverage of LanzaTech or fails to publish reports on LanzaTech regularly, our stock price or trading volume could decline.

***We may issue additional shares of common stock or other equity securities without your approval, which would dilute your ownership interests and may depress the market price of the common stock.***

As of the consummation of the Business Combination, we had warrants (including the AM Warrant) outstanding to purchase up to an aggregate of 12,574,276 shares of common stock and options (including the Options) outstanding to purchase up to an aggregate of 14,310,025 shares of common stock. Under the LanzaTech 2023 Long-Term Incentive Plan (the "2023 Plan"), we also have the ability to issue 19,622,273 shares of our common stock, and the Brookfield SAFE may convert into up to 5,000,000 shares of our common stock. The 2023 Plan is required to provide for the ability to grant and recycle the common stock (including any shares subject to forfeited options or restricted stock awards), and to initially reserve a number of shares of the common stock constituting 10% of the total number of shares of the common stock outstanding on a fully diluted basis, as determined at the closing of the Business Combination, and include an "evergreen" provision pursuant to which the number of shares reserved for issuance under the 2023 Plan will be increased automatically each year by 3% of the aggregate number of shares of the common stock then outstanding on a fully diluted basis. We may also issue additional shares of common stock or other equity securities of equal or senior rank in the future in connection with, among other things, future acquisitions or repayment of outstanding indebtedness, without stockholder approval, in a number of circumstances.

Our issuance of additional shares of common stock or other equity securities of equal or senior rank would have the following effects:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our existing stockholders' proportionate ownership interest in LanzaTech will decrease;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the amount of cash available per share, including for payment of dividends in the future, may decrease;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the relative voting strength of each previously outstanding share of common stock may be diminished; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the market price of shares of the common stock may decline.

***Our actual financial position and results of operations may differ materially from the unaudited pro forma condensed combined financial information included in this prospectus, which may not be indicative of what our actual financial position or results of operations would have been.***

The unaudited pro forma condensed combined financial information in this prospectus is presented for illustrative purposes only and is not necessarily indicative of what our actual financial position or results of

------

<u>[**Table of Contents**](#ib82e114cd19f45afae73e7a64e42f208_1390)</u>

operations would have been had the Business Combination been completed on the dates indicated. See the section titled "Unaudited Pro Forma Condensed Combined Financial Information" for more information.

***Because we do not anticipate paying any cash dividends on the common stock in the foreseeable future, capital appreciation, if any, will be your sole source of gains and you may never receive a return on your investment.***

We may retain future earnings, if any, for future operations, expansion and debt repayment and have no current plans to pay any cash dividends for the foreseeable future. Any decision to declare and pay dividends as a public company in the future will be made at the discretion of the Board and will depend on, among other things, our results of operations, financial condition, cash requirements, contractual restrictions and other factors that the Board may deem relevant. In addition, our ability to pay dividends may be limited by covenants of any existing and future outstanding indebtedness we or our subsidiaries incur. As a result, you may not receive any return on an investment in our securities unless you sell your securities for a price greater than that which you paid for it.

***The Public Warrants are identical to the Private Placement Warrants in material terms and provisions, except in certain circumstances, and are materially different from the LanzaTech warrants.***

The Public Warrants are identical to the Private Placement Warrants in material terms and provisions, except that the Private Placement Warrants are not transferable, assignable or salable until 30 days after the closing of the Business Combination (except in limited circumstances) and are not redeemable by us so long as they are held by the Sponsor or its permitted transferees. If the Private Placement Warrants are held by holders other than the Sponsor or its permitted transferees, they will be redeemable by us and exercisable by the holders on the same basis as the Public Warrants. The Sponsor agreed not to transfer, assign or sell any of the Private Placement Warrants until 30 days after the closing of the business combination.

We may redeem the Public Warrants prior to their exercise at a time that is disadvantageous to holders of Public Warrants. We have the ability to redeem outstanding Public Warrants at any time after they become exercisable and prior to their expiration, at a price of $0.01 per Public Warrant, provided that the closing price of the common stock equals or exceeds $18.00 per share (as adjusted for adjustments to the number of shares issuable upon exercise or the exercise price of a warrant) for any 20 trading days within a 30 trading day period commencing once the Public Warrants become exercisable and ending three days before we send the notice of redemption to Public Warrant holders. If and when the Public Warrants become redeemable by us, we may exercise the redemption right even if we are unable to register or qualify the underlying securities for sale under all applicable state securities laws. As a result, we may redeem the warrants as set forth above even if the holders are otherwise unable to exercise the warrants. Redemption of the outstanding Public Warrants could force holders of the Public Warrants (i) to exercise their Public Warrants and pay the exercise price therefor at a time when it may be disadvantageous for them to do so, (ii) to sell their Public Warrants at the then-current market price when they might otherwise wish to hold their Public Warrants or (iii) to accept the nominal redemption price which, at the time the outstanding Public Warrants are called for redemption, is likely to be substantially less than the market value of their Public Warrants. As noted above, none of the Private Placement Warrants will be redeemable by us so long as they are held by the Sponsor or its permitted transferees.

The terms of the Legacy LanzaTech warrants that were converted into New LanzaTech warrants at the closing of the Business Combination are materially different from those of the Public Warrants. The AM Warrant entitles its holder to purchase up to 300,000 shares of common stock at an exercise price equal to $10.00, and will expire on the fifth anniversary of the consummation of the Business Combination.

***You may only be able to exercise your Public Warrants on a "cashless basis" under certain circumstances, and if you do so, you will receive fewer shares of the common stock from such exercise than if you were to exercise such warrants for cash.***

The Warrant Agreement provides that in the following circumstances holders of warrants who seek to exercise their Public Warrants will not be permitted to do so for cash and will, instead, be required to do so on a cashless basis in accordance with Section 3(a)(9) of the Securities Act: (i) if the shares of common stock issuable upon exercise of the warrants are not registered under the Securities Act in accordance with the terms of the Warrant Agreement; (ii) if we have so elected and the shares of common stock is at the time of any exercise of a warrant not

------

<u>[**Table of Contents**](#ib82e114cd19f45afae73e7a64e42f208_1390)</u>

listed on a national securities exchange such that they satisfy the definition of "covered securities" under Section 18(b)(1) of the Securities Act; and (iii) if we have so elected and we call the Public Warrants for redemption. If you exercise your Public Warrants on a cashless basis, you would pay the warrant exercise price by surrendering the warrants for that number of shares of common stock equal to the quotient obtained by dividing (x) the product of the number of shares of common stock underlying the warrants, multiplied by the excess of the "fair market value" of our shares of common stock (as defined in the next sentence) over the exercise price of the warrants by (y) the fair market value. The "*fair market value*" is the average closing price of the shares of the common stock for the 10 trading days ending on the third trading day prior to the date on which the notice of exercise is received by the warrant agent or on which the notice of redemption is sent to the holders of warrants, as applicable. As a result, you would receive fewer shares of the common stock from such exercise than if you were to exercise such warrants for cash.

***Our warrant agreement designates the courts of the State of New York or the United States District Court for the Southern District of New York as the sole and exclusive forum for certain types of actions and proceedings that may be initiated by holders of our warrants, which could limit the ability of warrant holders to obtain a favorable judicial forum for disputes with our company.***

Our warrant agreement provides that, subject to applicable law, (i) any action, proceeding or claim against us arising out of or relating in any way to the Warrant Agreement, including under the Securities Act, will be brought and enforced in the courts of the State of New York or the United States District Court for the Southern District of New York, and (ii) that we irrevocably submit to such jurisdiction, which jurisdiction will be the exclusive forum for any such action, proceeding or claim. We will waive any objection to such exclusive jurisdiction and that such courts represent an inconvenient forum.

This choice-of-forum provision may limit a warrant holder's ability to bring a claim in a judicial forum that it finds favorable for disputes with our company, which may discourage such lawsuits against us and our directors, officers, or other employees and may result in increased litigation costs for our stockholders. Alternatively, if a court were to find this provision of the Warrant Agreement inapplicable or unenforceable with respect to one or more of the specified types of actions or proceedings, we may incur additional costs associated with resolving such matters in other jurisdictions, which could materially and adversely affect our business, financial condition and results of operations and result in a diversion of the time and resources of our management and board of directors.

***We may amend the terms of the Public Warrants in a manner that may be adverse to holders with the approval by the holders of at least 50% of the then-outstanding Public Warrants. As a result, the exercise price of a holder's Public Warrants could be increased, the exercise period could be shortened and the number of shares of the common stock purchasable upon exercise of a Public Warrant could be decreased, all without the approval of that warrant holder.***

Our Public Warrants were issued in registered form under the Warrant Agreement between Continental Stock Transfer & Trust Company, as warrant agent, and us. The Warrant Agreement provides that the terms of the Public Warrants may be amended without the consent of any holder to cure any ambiguity or correct any defective provision, but requires the approval by the holders of at least 50% of the then-outstanding Public Warrants to make

------

<u>[**Table of Contents**](#ib82e114cd19f45afae73e7a64e42f208_1390)</u>

any change that adversely affects the interests of the registered holders. Accordingly, we may amend the terms of the Public Warrants in a manner adverse to a holder if holders of at least 50% of the then-outstanding Public Warrants approve of such amendment. Although our ability to amend the terms of the Public Warrants with the consent of at least 50% of the then-outstanding Public Warrants is unlimited, examples of such amendments could be amendments to, among other things, increase the exercise price of the Public Warrants, convert the Public Warrants into cash or stock, shorten the exercise period or decrease the number of shares of common stock purchasable upon exercise of a Public Warrant.

***We and Legacy LanzaTech have identified material weaknesses in our internal control over financial reporting. While some of these material weaknesses have been remediated, they could continue to adversely affect our ability to report our results of operations and financial condition accurately and in a timely manner.***

Our management is responsible for establishing and maintaining adequate internal control over financial reporting designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with US GAAP. Our management is likewise required, on a quarterly basis, to evaluate the effectiveness of our internal controls and to disclose any changes and material weaknesses identified through such evaluation of those internal controls. A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of our annual or interim financial statements will not be prevented or detected on a timely basis.

AMCI previously identified a material weakness in its internal control over financial reporting related to the accounting for certain complex financial instruments issued by AMCI that were not effectively designed or maintained. This material weakness resulted in the restatement of AMCI's balance sheet as of August 6, 2021. Additionally, this material weakness could have resulted in a misstatement of complex financial instruments and related accounts and disclosures that would result in an additional material misstatement of AMCI's financial statements that would not be prevented or detected on a timely basis. As of September 30, 2022, this material weakness was remediated.

Additionally, AMCI has identified a quantitative and qualitative material weakness in its internal control over financial reporting related to the accounting of certain fees of Evercore related to advisory and placement agent services, which Evercore waived in connection with its resignation. Pursuant to an advisory agreement and a placement agency agreement that AMCI entered into with Evercore, AMCI agreed to pay Evercore an aggregate fee of approximately $8.0 million in connection with AMCI's initial business combination that was wholly contingent on the closing of its initial business combination. On or about October 11, 2022, AMCI determined that disclosure regarding such arrangements and aggregate fees of $8.0 million, which were reasonably estimable and reasonably possible, had been omitted from the footnotes contained in its previously-issued financial statements. AMCI's management evaluated the impact of the error on its internal control over financial reporting, and although the error had no impact to its condensed consolidated balance sheets, statements of cash flows or operations because such amount was never probable in accordance with the guidance set forth in ASC 450-20, the omission of such contingent payment from the footnotes to its financial statements was significant and therefore was determined to be a material error. Based on the above, AMCI's management concluded that the nondisclosure represented a material weakness in AMCI's internal control over financial reporting.

It is possible that we may identify other material weaknesses in the future. Our management has expended, and will continue to expend, a substantial amount of effort and resources for the improvement of our internal control over financial reporting. While we have processes to properly identify and evaluate the appropriate accounting technical pronouncements and other literature for all significant or unusual transactions, we have expanded and will continue to improve these processes to ensure that the nuances of such transactions are effectively evaluated in the context of the increasingly complex accounting standards.

Legacy LanzaTech has also identified material weaknesses in its internal control over financial reporting. The material weaknesses relate to the segregation of duties over manual journal entries and account reconciliations due to finance team size limitations; the design of formal accounting policies to analyze, account for, and disclose complex transactions; and the design, implementation, and documentation of internal controls at the entity level and

------

<u>[**Table of Contents**](#ib82e114cd19f45afae73e7a64e42f208_1390)</u>

certain reporting processes. During 2022, Legacy LanzaTech restated its previously issued 2020 and 2021 financial statements. The restatement resulted from certain material weaknesses, as described above. For additional information on the restatement, see Note 2 — *Summary of Significant Accounting Policies* to Legacy LanzaTech's 2020 and 2021 restated financial statements. LanzaTech is implementing measures designed to improve its internal control over financial reporting to remediate these material weaknesses, including hiring of additional accounting personnel. We believe the measures described above should remediate the material weaknesses identified and strengthen our internal control over financial reporting. While we continue the challenging and costly process to remediate the material weaknesses, we cannot predict the success of such plan or the outcome of our assessment of this plan until the remediation initiatives have been completed and have been operating effectively for a sufficient period of time.

We can give no assurance that these measures will remediate the deficiencies in internal control or that additional material weaknesses or significant deficiencies in internal control over financial reporting will not be identified in the future. Failure to implement and maintain effective internal control over financial reporting could result in material misstatements of our consolidated financial statements that may require us to restate our financial statements or cause us to fail to meet our periodic reporting obligations. As a result, we could be subject to sanctions or investigations by the stock exchange on which the common stock is listed, the SEC or other regulatory authorities. Failure to timely file will cause us to be ineligible to utilize short form registration statements on Form S-3 or Form S-4, which may impair our ability to obtain capital in a timely fashion to execute our business strategies or issue shares to effect an acquisition. In either case, there could result a material adverse effect on our business. The existence of material weaknesses or significant deficiencies in internal control over financial reporting could adversely affect our reputation or investor perceptions of LanzaTech, which could have a negative effect on the trading price of the common stock. In addition, we would incur additional costs to remediate material weaknesses in our internal control over financial reporting.

We are required, pursuant to Section 404 of the Sarbanes-Oxley Act, to furnish a report by management on, among other things, the effectiveness of our internal control over financial reporting for future annual reports on Form 10-K to be filed with the SEC. Failure to comply with the Sarbanes-Oxley Act could potentially subject us to sanctions or investigations by the SEC, Nasdaq or other regulatory authorities, which would require additional financial and management resources. However, for as long as we are an emerging growth company under the Jumpstart Our Business Startups Act of 2012, our independent registered public accounting firm will not be required to attest to the effectiveness of our internal control over financial reporting pursuant to Section 404 of the Sarbanes-Oxley Act. We could be an emerging growth company for up to five years from the last day of the fiscal year of AMCI's IPO.

***We may face litigation and other risks as a result of the material weaknesses in our internal control over financial reporting.***

As described elsewhere herein, we have identified a material weakness in our internal control over financial reporting related to the accounting for certain complex financial instruments issued by AMCI that were not effectively designed or maintained, which material weakness resulted in the restatement of AMCI's balance sheet as of August 6, 2021, and a material weakness in our internal control over financial reporting related to the accounting of certain fees of Evercore.

As a result of such material weaknesses, the restatement, the change in accounting for the financial instruments, and other matters raised or that may in the future be raised by the SEC, we face potential for litigation or other disputes which may include, among others, claims invoking the federal and state securities laws, contractual claims or other claims arising from the restatement and material weaknesses in our internal control over financial reporting and the preparation of our financial statements. As of the date hereof, we have no knowledge of any such litigation or dispute. However, we can provide no assurance that such litigation or dispute will not arise in the future. Any such litigation or dispute, whether successful or not, could have a material adverse effect on our business, results of operations and financial condition or our ability to complete a business combination.

***Delaware law and provisions in our certificate of incorporation and bylaws could make a takeover proposal more difficult.***

Our organizational documents are governed by Delaware law. Certain provisions of Delaware law and of our certificate of incorporation and bylaws could discourage, delay, defer or prevent a merger, tender offer, proxy contest or other change of control transaction that a stockholder might consider in its best interest, including those attempts that might result in a premium over the market price for the shares of the common stock held by our stockholders. These provisions include the ability of the Board to designate the terms of and issue new series of preference shares, supermajority voting requirements to amend certain provisions of our certificate of incorporation, the classification of the Board, and a prohibition on stockholder actions by written consent, which may make more difficult the removal of management and may discourage transactions that otherwise could involve payment of a premium over prevailing market prices for our securities.

These anti-takeover provisions as well as certain provisions of Delaware law could make it more difficult for a third party to acquire us, even if the third party's offer may be considered beneficial by many of our stockholders. As a result, our stockholders may be limited in their ability to obtain a premium for their shares. If prospective takeovers are not consummated for any reason, we may experience negative reactions from the financial markets, including negative impacts on the price of the common stock. These provisions could also discourage proxy contests and make it more difficult for stockholders to elect directors of their choosing and to cause us to take other corporate actions that our stockholders desire.

***Our certificate of incorporation designates the Court of Chancery of the State of Delaware as the sole and exclusive forum for certain types of actions and proceedings and the federal district courts as the sole and exclusive forum for other types of actions and proceedings, in each case, that may be initiated by our stockholders, which could limit our stockholders' ability to obtain what such stockholders believe to be a favorable judicial forum for disputes with Lus or our directors, officers or other employees or increase our stockholders' costs in bringing such a claim.***

Alternatively, if a court were to find these provisions of our certificate of incorporation inapplicable or unenforceable with respect to one or more of the specified types of actions or proceedings, we may incur additional costs associated with resolving such matters in other jurisdictions, which could materially adversely affect our

business, financial condition and results of operations and result in a diversion of the time and resources of our management and the Board.

***Our actual financial position and results of operations may differ materially from the unaudited pro forma financial information included in this prospectus.***

The unaudited pro forma condensed combined financial information included in this prospectus is presented for illustrative purposes only and is not necessarily indicative of what our actual financial position or results of operations would have been had the Business Combination been completed on the dates indicated. See "Unaudited Pro Forma Condensed Combined Financial Information" for more information.

***There can be no assurance that our warrants or the AM Warrant will be in the money at the time they become exercisable, and they may expire worthless.***

Subject to adjustment, the exercise price for the outstanding Public Warrants and Private Placement Warrants is $11.50 per share of common stock and the exercise price for the AM Warrant is $10.00 per share of common stock. If the market price for shares of common stock is less than the exercise price of a holder's warrant or AM Warrant, such holder may be less likely to exercise the warrants or the AM Warrant, as applicable, as such holder would be selling at a loss if they sold their common stock. There can be no assurance that such warrants or the AM Warrant will be in the money following the time they become exercisable and prior to their expiration, and as such, the warrants and the AM Warrant may expire worthless.

***The holders of the shares of common stock registered hereby may be willing to sell their shares at a price lower than the public market price.***

On February 10, 2023 the last reported sales price of the common stock was $7.30 per share. If the market price for shares of common stock is less than $10.00 per share, holders of shares of common stock would be selling at a loss if they purchased the shares of common stock at $10.00 per share. Because certain selling stockholders purchased shares privately at a price below the current market price, they may have an incentive to sell shares of their common stock because they could profit despite the market price of common stock falling below $10.00 per share. While these selling stockholders may, on average, experience a positive rate of return based on the current market price, public securityholders may not experience a similar rate of return on the securities they purchased due to differences in the purchase prices and the current market price. For example, based on the closing price of our common stock of $7.30 on February 10, 2023, the Sponsor and the AMCI Insiders would have a potential profit of up to approximately $7.295 per share that they purchased prior to the initial public offering of AMCI, or up to approximately $14.8 million in the aggregate (not giving effect to the issuance of common stock issuable upon exercise of the warrants held by them).

**USE OF PROCEEDS** 

We will not receive any proceeds from the sale of the Private Placement Warrants or of the common stock by the selling stockholders pursuant to this prospectus.

We will receive up to an aggregate of approximately $145 million from the exercise of the warrants, the AM Warrant and the Options, assuming the exercise in full of all of the warrants, the AM Warrant and the Options for cash. To the extent that the warrants, the AM Warrant and the Options are exercised on a "cashless basis," the amount of cash we would receive from the exercise of the warrants, the AM Warrant and the Options will decrease. We expect to use the net proceeds from the exercise of the warrants, the AM Warrant and the Options for general corporate purposes. We will have broad discretion over the use of proceeds from the exercise of the warrants, the AM Warrant and the Options.

There is no assurance that the holders of the warrants or the AM Warrant will elect to exercise any or all of such warrant, or that the holders of Options will elect to exercise any or all of such Optionss. If the market price for shares of common stock is less than the exercise price of a holder's warrant,the AM Warrant or the Options, such holder may be less likely to exercise the warrants, the AM Warrant or the Options, as applicable, as such holder would be selling at a loss if they sold their common stock. Subject to adjustment, the exercise price of the warrants is $11.50 per share and the exercise price of the AM Warrant is $10.00 per share. Subject to adjustment, the exercise prices of the Options range from $1.07 per share to $3.15 per share. On February 10, 2023 the last reported sales price of the common stock was $7.30 per share. Additionally, if the market price for shares of common stock is less than $10.00 per share, holders of shares of common stock would be selling at a loss if they purchased the shares of common stock at $10.00 per share. Because certain selling stockholders purchased shares privately at a price below the current market price, they may have an incentive to sell shares of their common stock because they could profit despite the market price of common stock falling below $10.00 per share. While these selling stockholders may, on average, experience a positive rate of return based on the current market price, public securityholders may not experience a similar rate of return on the securities they purchased due to differences in the purchase prices and the current market price. For example, based on the closing price of our common stock of $7.30 on February 10, 2023, the Sponsor and AMCI Insiders would have a potential profit of up to approximately $7.295 per share that they purchased prior to the initial public offering of AMCI, or up to approximately $14.8 million in the aggregate (not giving effect to the issuance of common stock issuable upon exercise of the warrants held by them).

**Introduction**

New LanzaTech is providing the following unaudited pro forma condensed combined financial information to aid you in your analysis of the financial aspects of the Business Combination.

AMCI was a blank check company formed for the purpose of entering into a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or similar business combination with one or more businesses.

The registration statement for AMCI's IPO became effective on August 3, 2021. On August 6, 2021, AMCI consummated its IPO of 15,000,000 units. Each unit consists of one share of Class A common stock, and one-half of one redeemable warrant, each whole warrant entitling the holder thereof to purchase one share of Class A common stock for $11.50 per share. The units were sold at $10.00 per unit, generating gross proceeds to AMCI of $150.0 million, and incurring offering costs of approximately $7.3 million, inclusive of approximately $5.3 million in deferred underwriting commissions. The underwriters were granted a 45-day option from the date of the underwriting agreement (August 3, 2021) to purchase up to 2,250,000 additional units to cover over-allotments, at $10.00 per unit. On September 17, 2021, the over-allotment option expired, resulting in the forfeiture of 562,500 founder shares.

Simultaneously with the closing of the IPO, AMCI consummated the sale of an aggregate of 3,500,000 Private Placement Warrants at a price of $1.00 per Private Placement Warrant, generating gross proceeds to AMCI of $3.5 million. No underwriting discounts or commissions were paid with respect to such sales.

Upon closing of the IPO and sale of Private Placement Warrants, $150.0 million was placed in the trust account established in connection with the IPO (the "Trust Account").

AMCI had 24 months from the closing of the IPO (by August 6, 2023) to complete an initial business combination.

LanzaTech was founded in 2005 in New Zealand and was headquartered in Skokie, Illinois. LanzaTech is a nature-based carbon refining company that transforms waste carbon into materials such as sustainable fuels, fabrics, and packaging that people use in their daily lives.

The unaudited pro forma condensed combined balance sheet as of September 30, 2022 combines the unaudited condensed balance sheet of AMCI and the unaudited condensed consolidated balance sheet of LanzaTech on a pro forma basis as if the Business Combination and the related transactions contemplated by the Merger Agreement, summarized below, had been consummated on September 30, 2022. The unaudited pro forma condensed combined statements of operations for the nine months ended September 30, 2022 and for the year-ended December 31, 2021 combine the historical statements of operation of AMCI and LanzaTech for such periods on a pro forma basis as if the Business Combination and related transactions, summarized below, had been consummated on January 1, 2021, the beginning of the earliest period presented. The related transactions that are given pro forma effect include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the reverse recapitalization between AMCI and LanzaTech;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the net proceeds from the issuance of 18,500,000 shares of New LanzaTech common stock in connection with the Private Placement;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the net proceeds from the issuance of the Brookfield SAFE; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the Forward Purchase Agreement between AMCI, LanzaTech and ACM.

The unaudited pro forma condensed combined financial information may not be useful in predicting the future financial condition and results of operations of New LanzaTech. The actual financial position and results of operations of New LanzaTech may differ significantly from the pro forma amounts reflected herein due to a variety of factors.

The historical financial information of AMCI was derived from the unaudited financial statements of AMCI as of and for the nine months ended September 30, 2022 and the audited financial statements of AMCI as of December 31, 2021 and for the period from August 3, 2021 (inception) through December 31, 2021, which are included elsewhere in this prospectus. The historical financial information of LanzaTech was derived from the unaudited condensed consolidated financial statements of LanzaTech as of and for the nine months ended September 30, 2022 and the audited consolidated financial statements of LanzaTech as of and for the year ended December 31, 2021, which are included elsewhere in this prospectus. This information should be read together with AMCI's and LanzaTech's audited financial statements and related notes, the section titled "Management's Discussion and Analysis of Financial Condition and Results of Operations" and other financial information included elsewhere in this prospectus.

LanzaTech, AMCI and ACM executed the Forward Purchase Agreement on February 3, 2023. Pursuant to the Forward Purchase Agreement, ACM obtained 5,916,514 Recycled Shares on the open market for approximately $10.16 per share ("Redemption Price"), and such purchase price of $60.1 million was funded by the use of Trust Account proceeds as a prepayment ("Prepayment Amount") for the Forward Purchase Agreement redemption at the end of three years ("Maturity Date"). ACM has the right at the end of three years to return the shares and keep the Prepayment Amount plus the fees described below, or may, at ACM's sole discretion, to partially or fully terminate this transaction over the course of the three year term by returning cash in an amount equal to the number of shares terminated from time to time ("Terminated Shares") multiplied by the Redemption Price, which price may be reduced in the case of certain dilutive events ("Reset Price").

At the end of the three-year term, New LanzaTech is obligated to pay ACM an amount equal to the product of (1) 7,500,000 less (b) the number of Terminated Shares multiplied by (2) $2.00 (the "Maturity Consideration"). In addition to the Prepayment Amount and the Maturity Consideration, on the Maturity Date, New LanzaTech shall pay to ACM an amount equal to the product of (x) 500,000 and (y) the Redemption Price, totalling $5.1 million (the "Share Consideration").

In addition, ACM may request, at its sole discretion, warrants of New LanzaTech exercisable for shares in an amount equal to 10,000,000 less the number of Recycled Shares ("Shortfall Warrants"). The Shortfall Warrants warrants have an exercise price equal to the Reset Price. The form of the Shortfall Warrants shall be agreed upon by LanzaTech, AMCI and ACM within 45 days of the executed Forward Purchase Agreement. ACM has requested 4,083,486 Shortfall Warrants based on the number of Recycled Shares purchased. In connection with the Forward Purchase Agreement, ACM assigned its rights, duties and obligations with respect to a portion of the shares purchased under the Forward Purchase Agreement to Vellar Opportunity Fund SPV LLC - Series 10.

The Business Combination closed on February 8, 2023 and was accounted for as a reverse recapitalization, in accordance with US GAAP. Under this method of accounting, AMCI was treated as the "acquired" company for financial reporting purposes. Accordingly, the Business Combination was treated as the equivalent of LanzaTech issuing stock for the net assets of AMCI, accompanied by a recapitalization. The net assets of AMCI were stated at historical cost, with no goodwill or other intangible assets recorded. Operations prior to the Business Combination are those of LanzaTech.

LanzaTech was determined to be the accounting acquirer based on evaluation of the following facts and circumstances:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• LanzaTech stockholders have the largest portion of voting rights (85.3%) in New LanzaTech;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• LanzaTech's existing senior management team comprise senior management of New LanzaTech;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The operations of New LanzaTech primarily represent operations of LanzaTech; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• In comparison with AMCI, LanzaTech has significantly more revenues and total assets.

**Description of the Business Combination**

The aggregate consideration for the Business Combination will be payable in the form of shares of New LanzaTech common stock.

The following summarizes the purchase consideration:

---

| | |
|:---|:---|
| Total shares transferred<sup>(1)</sup> | 167324363 |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Value per share<sup>(2)</sup> | $10.00 |
| **Total share consideration**  | $**1673243630** |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Options exchanged<sup>(3)</sup> | 143756370 |
| **Total equity value**<sup>(4</sup><sup>)</sup>  | $**1817000000** |

---

__________________

(1)Total shares transferred include the conversion of LanzaTech RSAs to New LanzaTech RSAs in accordance with the Merger Agreement. Total shares transferred do not include LanzaTech options. See note (3) for further information on these instruments.

(2)Total share consideration is calculated using a $10.00 per-share reference price. The closing share price of the Business Combination was determined on the Closing Date. As the Business Combination was accounted for as a reverse recapitalization, the value per share is disclosed for informational purposes only in order to indicate the fair value of shares transferred.

(3)Options exchanged represents the conversion of LanzaTech options into New LanzaTech options in accordance with the Merger Agreement. These options are not assumed to be exercised for the purposes of the unaudited pro forma condensed combined financial information and, therefore, have not been included in Total share consideration. The value of the options represents the number of shares that would be issued under the option agreements assuming full cash exercise. Those shares are valued at the $10.00 per-share reference price.

(4)Total equity value includes the value of the exchanged options assuming full cash exercise of all such instruments. The total equity value is equal to the equity value of $1,817.0 million outlined in the Merger Agreement.

The following summarizes the pro forma shares of New LanzaTech Common Stock outstanding:

---

| | | |
|:---|:---|:---|
| | **Shares outstanding** | **%** |
| AMCI Public Stockholders | 1981860 | 1.0% |
| AMCI Shares subject to Forward Purchase Agreement<sup>(1)</sup> | 5916514 | 3.0% |
| AMCI Insiders<sup>(2)</sup> | 2500000 | 1.3% |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Total AMCI Shares | 10398374 | 5.3% |
| Legacy LanzaTech stockholders | 167324363 | 85.3% |
| PIPE Investors | 18500000 | 9.4% |
| **Pro Forma New LanzaTech Common Stock at September 30, 2022**<sup>(3)</sup>  | 196222737 | 100.0% |

---

__________________

(1)Represents shares purchased by ACM as part of the Forward Purchase Agreement described in Footnote N below. These shares are redeemable at the option of ACM and have been classified as redeemable common stock.

(2)1,250,000 AMCI Insider shares were cancelled and re-issued to public shareholders whereby those public shareholders agreed not to redeem their Class A common stock in connection with the Business Combination. The transfer of AMCI Insider shares served as an incentive for public shareholders to not redeem. These shares remain outstanding following the Closing and are reflected in this table as part of the AMCI Public Stockholders share count.

(3)Amounts and percentages exclude all LanzaTech options (including vested LanzaTech options) as they are not outstanding common stock at the time of Closing. Further, these amounts also exclude the 11,000,000 warrants outstanding to acquire AMCI Class A common stock as these were outstanding at the closing of the Business Combination. Additionally, amounts and percentages reflect no election by Brookfield or ArcelorMittal to convert any portion of the Brookfield SAFE or AM Warrant into shares of New LanzaTech common stock following the Closing.

The following unaudited pro forma condensed combined balance sheet as of September 30, 2022 and the unaudited pro forma condensed combined statement of operations for the nine months ended September 30, 2022 and the year ended December 31, 2021 are based on the historical financial statements of AMCI and LanzaTech.

**NOTES TO UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION**

**1. Basis of Presentation**

The Business Combination was accounted for as a reverse recapitalization in accordance with US GAAP. Under this method of accounting, AMCI was treated as the "acquired" company for financial reporting purposes. Accordingly, the Business Combination was treated as the equivalent of LanzaTech issuing stock for the net assets of AMCI, accompanied by a recapitalization. The net assets of AMCI were stated at historical cost, with no goodwill or other intangible assets recorded. Operations prior to the Business Combination are those of LanzaTech.

The unaudited pro forma condensed combined balance sheet as of September 30, 2022 assumes that the Business Combination occurred on September 30, 2022. The unaudited pro forma condensed combined statements of operations for the nine months ended September 30, 2022 and the year ended December 31, 2021 give pro forma effect to the Business Combination as if it had been completed on January 1, 2021. These periods are presented on the basis of LanzaTech as the accounting acquirer.

The unaudited pro forma condensed combined balance sheet as of September 30, 2022 has been prepared using, and should be read in conjunction with, the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• AMCI's unaudited condensed balance sheet as of September 30, 2022 and the related notes as of and for the period ended September 30, 2022, included elsewhere in this prospectus; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• LanzaTech's unaudited condensed consolidated balance sheet as of September 30, 2022 and the related notes as of and for the period ended September 30, 2022, included elsewhere in this prospectus.

The unaudited pro forma condensed combined statements of operations for the nine months ended September 30, 2022 and for the year ended December 31, 2021 have been prepared using, and should be read in conjunction with, the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• AMCI's unaudited condensed statement of operations for the nine months ended September 30, 2022 and the audited statement of operations for the period from August 6, 2021 (inception) through December 31, 2021 included elsewhere in this prospectus; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• LanzaTech's unaudited condensed consolidated statement of operations and comprehensive loss for the nine months ended September 30, 2022 and the audited consolidated statement of operations and comprehensive loss for the year ended December 31, 2021 included elsewhere in this prospectus.

Management has made significant estimates and assumptions in its determination of the pro forma adjustments. As the unaudited pro forma condensed combined financial information has been prepared based on these preliminary estimates, the final amounts recorded may differ materially from the information presented.

The unaudited pro forma condensed combined financial information does not give effect to any anticipated synergies, operating efficiencies, tax savings, or cost savings that may be associated with the Business Combination.

The pro forma adjustments reflecting the consummation of the Business Combination are based on certain currently available information and certain assumptions and methodologies that management believes are reasonable under the circumstances. The unaudited combined pro forma adjustments, which are described in the accompanying notes, may be revised as additional information becomes available and is evaluated. Therefore, it is likely that the actual adjustments will differ from the pro forma adjustments and it is possible the differences may be material. Management believes that its assumptions and methodologies provide a reasonable basis for presenting all of the significant effects of the Business Combination based on information available to management at this time and that the pro forma adjustments give appropriate effect to those assumptions and are properly applied in the unaudited pro forma condensed combined financial information.

**2. Adjustments to Unaudited Pro Forma Condensed Combined Financial Information**

The unaudited pro forma condensed combined financial information has been prepared to illustrate the effect of the Business Combination and has been prepared for informational purposes only.

The unaudited pro forma information has been prepared in accordance with Article 11 of Regulation S-X as amended by the final rule, Release No. 33-10786, "Amendments to Financial Disclosures about Acquired and Disposed Businesses." Release No. 33-10786 replaces the existing pro forma adjustment criteria with simplified requirements to depict the accounting for the transaction ("*Transaction Accounting Adjustments*") and present the reasonably estimable synergies and other transaction effects that have occurred or are reasonably expected to occur ("*Management's Adjustments").* Management has elected not to present Management's Adjustments and will only be presenting Transaction Accounting Adjustments in the unaudited pro forma condensed combined financial information.

The pro forma basic and diluted loss per share amounts presented in the unaudited pro forma combined statements of operations are based upon the number of shares of New LanzaTech common stock outstanding, assuming the Business Combination occurred on January 1, 2021.

***Adjustments to Unaudited Pro Forma Condensed Combined Balance Sheet***

The adjustments included in the unaudited pro forma condensed combined balance sheet as of September 30, 2022 are as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(A)Reflects the following reclassifications on the balance sheet to align presentation:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Reflects the reclassification of $0.3 million of prepaid expenses - current into $0.3 million of other current assets.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Reflects the reclassification of $1.4 million of accrued expenses and $0.2 million of franchise tax payable to other accrued liabilities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(B)Reflects the reclassification of $151.0 million of marketable securities held in the Trust Account at the balance sheet date that becomes available at the closing of the Business Combination. This amount is reduced by the $84.8 million in cash that was paid to redeeming shareholders for the 8,351,626 shares of Class A common stock subject to redemption that were redeemed at a per share redemption price of $10.16.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(C)Reflects the payment of $0.2 million of deferred underwriting fees payable that were incurred in connection with the IPO. The fees were paid at the close of the Business Combination.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(D)Represents the settlement of transaction costs of both AMCI and LanzaTech related to the Business Combination of $12.2 million, in addition to the $0.2 million of deferred underwriting fees noted above, inclusive of advisory, banking, printing, legal and accounting fees that are capitalized into additional paid-in capital as a reduction to proceeds. The unaudited pro forma condensed combined balance sheet reflects these costs as a reduction of cash of $11.8 million as $0.4 million have been paid as of September 30, 2022. $2.2 million in other accrued liabilities and $1.6 million in accounts payable was accrued between both AMCI and LanzaTech as of September 30, 2022. $1.2 million was capitalized on LanzaTech's balance sheet as of September 30, 2022. Adjustment to accumulated deficit of $3.1 million represents the capitalization of transaction costs expensed by AMCI through September 30, 2022.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(E)Represents the net proceeds from the Private Placement of 18,500,000 shares of Class A common stock, par value $0.0001, at $10.00 per share. Proceeds from the Private Placement totaled $155.0 million as 3,000,000 shares of Class A common stock were issued under the AM SAFE in satisfaction of the related liability recorded on LanzaTech's balance sheet. Additionally, the AM SAFE is effectively adjusted to $30.0 million immediately prior to its conversion to shares through an entry to accumulated deficit for $2.8 million. See footnote EE for further details.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(F)Represents the issuance of the Brookfield SAFE for $50.0 million. At the time of issuance, none of the Brookfield SAFE automatically converts to New LanzaTech common stock as a result of the Business Combination. Conversion only occurs at the option of Brookfield as no equity funding has occurred. As a result, the Brookfield SAFE is reflected as a mark-to-market liability on the pro forma balance sheet. There is no associated pro forma income statement impact as the Brookfield SAFE was not outstanding in the periods presented where a mark-to-market adjustment could be calculated. Management is still assessing the full accounting impact of this arrangement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(G)Represents the implied declaration of the $241.5 million unpaid cumulative dividends immediately prior to the conversion of LanzaTech preferred shares into LanzaTech common shares. As required by the Merger Agreement, all unpaid cumulative dividends on LanzaTech preferred shares are converted to shares of New LanzaTech common stock by dividing the total cumulative dividends by $10.00. This conversion occurs in footnote H. The dividend accrual was calculated through February 8, 2023, the Closing Date.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(H)Represents recapitalization of LanzaTech through the issuance of 167,324,363 shares of New LanzaTech common stock to LanzaTech shareholders as consideration for the reverse recapitalization, including the settlement of LanzaTech preferred shares into shares of New LanzaTech common stock and the settlement of the cumulative unpaid dividend on the LanzaTech preferred shares into shares of New LanzaTech common stock as discussed in footnote G. LanzaTech preferred shares were converted into LanzaTech common shares prior to the reverse recapitalization on a one for one basis.

Additionally, this adjustment reflects the net exercise of all outstanding warrants to purchase up to an aggregate of 225,223 shares of LanzaTech common stock granted by LanzaTech to Venture Lending and Leasing VI, Inc. in September 2012, and to Venture Lending and Leasing VII, Inc. and Venture Lending and Leasing VIII, Inc. in November 2016 (collectively, the "VLL Warrants") into LanzaTech common shares immediately prior to the reverse capitalization. The $1.6 million liability for these warrants is derecognized as a result of the exercise.

Holders of LanzaTech common shares received per share consideration of 4.37 shares of New LanzaTech common stock.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(I)Represents the conversion and accelerated vesting of LanzaTech options into New LanzaTech options where the option agreement includes a performance condition that accelerated vesting as a result of the Business Combination.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(J)Represents the conversion and accelerated vesting of LanzaTech RSAs into the New LanzaTech RSAs.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(K)Reflects the reclassification of the AM Warrant from liability to equity upon close of the Business Combination as the warrant became exercisable for a fixed number of shares at a fixed exercise price at the time of the Business Combination.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(L)Reflects the reclassification of $65.5 million of Class A common stock subject to possible redemption that were ultimately not redeemed to permanent equity.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(M)Reflects the elimination of AMCI's historical accumulated deficit to additional paid-in capital. The amount eliminated is adjusted for the amount of AMCI historical accumulated deficit already reclassified in footnote D.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(N)Reflects the Forward Purchase Agreement. The combination of the Prepayment Amount (reflected as a cash outflow of $60.5 million, inclusive of $0.4 million in stock acquisition fees in this adjustment) and ACM's optional early termination economically result in the arrangement being akin to a prepaid written put option on 5,916,514 Class A common shares. Because prepaid, New LanzaTech is entitled over the 36 month maturity period to either a return of cash or a return of shares, which ACM will determine at its sole discretion.

------

<u>[**Table of Contents**](#ib82e114cd19f45afae73e7a64e42f208_1390)</u>

The Forward Purchase Agreement is therefore evaluated as a prepaid redemption contract that meets the definition of a derivative and is initially valued at an estimated closing date fair value of $13.0 million. The value of the derivative is comprised of the Prepayment Amount, and is reduced by the economics of the downside protection provided to ACM, the Maturity Consideration on non-terminated shares and the Share Consideration, reducing the value of the Prepayment Amount by $47.1 million. The derivative will be remeasured to fair value with changes reflected in earnings in future periods. The accounting for the forward purchase agreement asset, as well as the final valuation, are still under evaluation and may be subject to change.

Expensed transaction costs in the amount of $0.5 million are reflected as an adjustment to accumulated deficit.

The difference between the Prepayment Amount and fair value of the derivative is recorded through accumulated deficit as a one-time charge reflecting the cost of entering the Forward Purchase Agreement.

The 5,916,514 Class A common shares purchased by ACM are classified as redeemable common shares as such shares may be redeemed with the settlement of the derivative asset solely at ACM's election. These shares are reclassified to Class A common stock subject to possible redemption from Class A common stock and recorded at their maximum redemption value of $60.1 million on the unaudited pro forma condensed combined balance sheet. The reclassification of shares is recorded through additional paid-in capital.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(O)Reflects the issuance of 4,083,486 Shortfall Warrants to ACM in connection with the Forward Purchase Agreement. The form of these warrants will be negotiated between ACM and New LanzaTech within 45 days of the executed Forward Purchase Agreement. For the purpose of the pro forma financial information, these warrants are assumed to be liability classified and have a 3 year term. The Shortfall Warrant value is recorded to derivative warrant liabilities, with an offsetting entry to accumulated deficit. As the form of the warrant has not yet been determined, the classification and valuation of these warrants is subject to change based on the final form agreed between the parties.

***Adjustments to Unaudited Pro Forma Condensed Combined Statements of Operations***

The pro forma adjustments included in the unaudited pro forma condensed combined statements of operations for the nine months ended September 30, 2022 and year ended December 31, 2021 are as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(AA)Reflects the following reclassifications on the combined statement of operations to align presentation:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Reflects the reclassification of general and administrative expense, franchise tax expense and capital-based tax expense into selling, general and administrative expense.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Reflects the reclassification of change in fair value of derivative warrant liabilities into other (expense) income, net.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Reflects the reclassification of offering costs allocated to derivative warrant liabilities into other (expense) income, net. This reclassification only applies to the year ended December 31, 2021.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(BB)Reflects the elimination of investment income on the Trust Account and the gain from the settlement of deferred underwriting fees resulting from the resignation of Evercore. As this gain resulting from Evercore's resignation occurred prior to Closing and is recorded by AMCI, the gain is reversed.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(CC)Reflects the expense related to the conversion and accelerated vesting of LanzaTech options into New LanzaTech options where the option agreement includes a performance condition that accelerated vesting as a result of the Business Combination. This expense is split between selling, general and administrative expense and research and development expense based on where the related employees' compensation expense is recorded.

------

<u>[**Table of Contents**](#ib82e114cd19f45afae73e7a64e42f208_1390)</u>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(DD)Reflects the expense related to the conversion and accelerated vesting of LanzaTech RSAs into New LanzaTech RSAs. This expense is split between selling, general and administrative expense and research and development expense based on where the related employees' compensation expense is recorded.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(EE)Reflects the mark-to-market adjustment on the AM SAFE liability to increase the value of the liability to $30.0 million at the time of settlement as 3,000,000 shares of New LanzaTech common stock valued at $10.00 per share are to be issued in satisfaction of the SAFE liability.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(FF)Reflects the reversal of the fair value adjustment on the AM Warrant as the AM Warrant is equity classified upon close of the Business Combination (see footnote K above). As the AM Warrant was issued in December 2021, there is no associated mark-to-market adjustment on the statement of operations for the year-ending December 31, 2021.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(GG)Reflects the reversal of the fair value adjustment on the AM SAFE as the AM SAFE is satisfied upon close of the Business Combination (see footnote E above).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(HH)Reflects the reversal of the fair value adjustment on the VLL Warrants, which were exercised immediately prior to the close of the Business Combination (see Footnote H above).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(II)Reflects the reversal of capitalizable transaction costs which would not have been expensed had the transaction taken place on January 1, 2021.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(JJ)Reflects the transaction costs related to the issuance of the Forward Purchase Agreement as if the transaction had taken place on January 1, 2021. These transaction costs are included in selling, general and administrative expense. Lastly, this reflects the one-time, non-cash charge of entering into the Forward Purchase Agreement, which are included in other (expense) income, net. See Footnote N for further details.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(KK)Represents the expense on the Shortfall Warrants issued in connection with the Forward Purchase Agreement (see Footnote O above).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(LL)LanzaTech has significant deferred tax assets in the jurisdictions in which it operates. The ability to realize deferred tax assets depends on LanzaTech's ability to generate sufficient taxable income within the carryforward periods provided for in the tax law for each tax jurisdiction. The valuation allowances recorded against deferred tax assets generated by taxable losses in certain jurisdictions will affect the provision for income taxes until the valuation allowances are released.

The unaudited pro forma condensed combined financial information assumes these deferred tax assets and the related valuation allowance will transfer to New LanzaTech, so New LanzaTech's provision for income taxes will include no tax benefit for losses incurred in these jurisdictions until the respective valuation allowance is eliminated. As a result, there has been no tax effect applied to any of the pro forma adjustments detailed above as the valuation allowances remain outstanding during the period of the unaudited pro forma condensed combined statement of operations.

For the nine months ended September 30, 2022, the income tax expense recorded by AMCI has been reversed from the unaudited pro forma condensed combined statement of operations due to the expectations noted here. The associated current tax liability on the unaudited pro forma condensed combined balance sheet as of September 30, 2022 has not been reversed as the Business Combination does not trigger its settlement.

(MM)Reflects the elimination of the unpaid cumulative dividend on LanzaTech preferred shares as all LanzaTech preferred shares were converted into New LanzaTech common stock at the closing of the Business Combination. New LanzaTech did not have any outstanding preferred shares at the closing of the Business Combination.

**3. Loss per Share**

Represents the net loss per share calculated using the historical weighted average shares outstanding, and the issuance of additional shares in connection with the Business Combination, assuming the shares were outstanding since January 1, 2021. As the Business Combination and related equity transactions are being reflected as if they had occurred at the beginning of the period presented, the calculation of weighted average shares outstanding for basic and diluted net income (loss) per share assumes that the shares issued relating to the Business Combination have been outstanding for the entirety of the period presented.

__________________

(1)As LanzaTech had a net loss on a pro forma combined basis, the outstanding New LanzaTech options and the outstanding New LanzaTech warrants have no impact to diluted net loss per share as they are considered anti-dilutive.

(2)If Brookfield were to convert the Brookfield SAFE to 5,000,000 shares of New LanzaTech common stock, the pro forma loss per share would be as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;a.For the nine months ended September 30, 2022: $(0.26)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;b.For the year ended December 31, 2021: $(0.62)

**MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS** 

*The following discussion and analysis should be read in conjunction with LanzaTech's financial statements and related notes included elsewhere in this prospectus. This discussion and analysis and other parts of this prospectus contain forward-looking statements based upon current beliefs, plans and expectations that involve risks, uncertainties, and assumptions. LanzaTech's actual results and the timing of selected events could differ materially from those anticipated in these forward-looking statements as a result of several factors, including those set forth under "Risk Factors" and elsewhere in this prospectus. You should carefully read the "Risk Factors" section of this prospectus to gain an understanding of the important factors that could cause actual results to differ materially from any such forward-looking statements. Please also see "Forward-Looking Statements." In this section, unless otherwise indicated or the context otherwise requires, references in this section to "New LanzaTech," the "Company," "we," "us," "our" and other similar terms refer to LanzaTech Global, Inc. and its consolidated subsidiaries, including LanzaTech NZ, Inc. and its consolidated subsidiaries subsequent to the Business Combination. References to "LanzaTech" and "Legacy LanzaTech" refer to LanzaTech NZ, Inc. and its consolidated subsidiaries prior to the Business Combination and references to "AMCI" refer to AMCI Acquisition Corp. II prior to the Business Combination.*

**Overview**

We are a nature-based carbon refining company that transforms waste carbon into the chemical building blocks for consumer goods such as sustainable fuels, fabrics, and packaging that people use in their daily lives. Our customers leverage our proven proprietary gas fermentation technology platform to convert certain feedstock, including waste carbon gases, into sustainable fuels and chemicals such as ethanol. We are focused on taking advantage of the many uses of ethanol while capitalizing on the growing preference among major companies for renewable products and environmentally-conscious manufacturing processes.

LanzaTech performs research and development ("R&D") services related to novel technologies and development of biocatalysts for commercial applications, mainly to produce fuels and chemicals. We primarily employ a licensing business model whereby our customers build, own and operate facilities that use our technology, and in return, we are paid a royalty fee based on the revenue generated by the customer from the use of our technology. We began operations in 2005 and in 2018, we established the world's first commercial waste gas to ethanol plant in China, followed by a second and a third one in 2021 and 2022, respectively, also in China, with others currently in development in various countries around the world.

We have not achieved operating profitability since our formation. Our net losses after tax were $(55.0) million for the nine months ended September 30, 2022 and $(30.6) million for the nine months ended September 30, 2021. As of September 30, 2022 we had an accumulated deficit of $(434.9) million compared to an accumulated deficit of $(379.9) million as of December 31, 2021. We anticipate that we will continue to incur losses until we sufficiently commercialize our technology.

**The Business Combination**

On March 8, 2022, AMCI entered into the Merger Agreement with Legacy LanzaTech and Merger Sub. On February 8, 2023, upon the terms and subject to the satisfaction or waiver of the conditions described in the Merger Agreement, including approval of the transaction by the AMCI Stockholders and LanzaTech stockholders, Merger Sub merged with and into LanzaTech. Upon consummation of the Business Combination, the separate corporate existence of Merger Sub ceased, and LanzaTech survived the Business Combination and became a wholly owned subsidiary of AMCI. In addition, in connection with the consummation of the Business Combination, the combined company was renamed "LanzaTech Global, Inc." and is referred to in this section as "New LanzaTech."

***Accounting Impact of the Business Combination***

The Business Combination is being accounted for as a reverse recapitalization. LanzaTech is the accounting predecessor and New LanzaTech is the successor SEC registrant, meaning that LanzaTech's financial statements for previous periods will be disclosed in New LanzaTech's periodic reports filed with the SEC.

------

<u>[**Table of Contents**](#ib82e114cd19f45afae73e7a64e42f208_1390)</u>

Under this method of accounting, AMCI is treated as the acquired company for financial statement reporting purposes. For accounting purposes, LanzaTech is deemed to be the accounting acquirer in the transaction and, consequently, the transaction is treated as a recapitalization of LanzaTech (i.e., a capital transaction involving the issuance of stock by AMCI for the stock of LanzaTech). Accordingly, the condensed consolidated balance sheets and results of operations of LanzaTech are the historical financial statements of New LanzaTech, and AMCI's assets, liabilities and results of operations have been consolidated with LanzaTech's as of the acquisition date. Operations prior to the Business Combination are presented as those of LanzaTech. The net assets of LanzaTech are recognized at carrying value, with no goodwill or other intangible assets recorded.

The most significant change in New LanzaTech's financial position and results is a $198.6 million net increase in cash and cash equivalents and a $584.4 million net increase in total stockholders' equity, in each case as compared to LanzaTech's condensed consolidated balance sheet as of September 30, 2022. See"Unaudited Pro Forma Condensed Combined Financial Information" for additional information.

**Restatement of Previously Issued Consolidated Financial Statements**

The accompanying Management's Discussion and Analysis of Financial Condition and Results of Operations gives effect to the restatement adjustments made to the previously reported consolidated financial statements of Legacy LanzaTech as of and for the years ended December 31, 2021 and 2020. For additional information and a detailed discussion of the restatement, see Note 2, "Summary of Significant Accounting Policies—Restatement" in our consolidated financial statements, which are included elsewhere in this proxy prospectus.

**Factors Affecting Our Performance**

We believe that our performance and future success depend on several factors that present significant opportunities for New LanzaTech but also pose risks and challenges.

With respect to New LanzaTech's business, we have identified several potential risk factors, including (i) the history of LanzaTech's net losses and the fact that New LanzaTech anticipates incurring further losses going forward; (ii) New LanzaTech's reliance upon industry partners to effect our growth strategy and to execute our business plan; (iii) New LanzaTech owns and anticipates acquiring additional equity interests in several of our customers' plants and has exposure to the volatility and liquidity risks inherent in holding such equity; (iv) the concentration of New LanzaTech's revenue in a limited number of customers and the fact that our growth will depend on expanding that customer base; (v) rapidly changing technology and extensive competition for technologies addressing decarbonization; (vi) the protection of New LanzaTech's intellectual property; (vii) construction risks, including failure to complete projects on time or in a cost effective manner; (viii) potential requirements for additional financing to fund operations and complete the development and commercialization of new products or new aspects of existing process technologies; (ix) the fluctuating availability and cost of waste based feedstocks used in New LanzaTech's process; (x) volatility in commodity chemicals prices and the associated impact on New LanzaTech's royalty revenue and CarbonSmart revenues and (xi) market conditions and geopolitical factors. For additional information regarding risks facing our business, see "Risk Factors*.*"

**Basis of Presentation**

LanzaTech's condensed consolidated financial statements were prepared in accordance with US GAAP. See Note 2 to our condensed consolidated financial statements, included elsewhere in this prospectus, for a full description of our basis of presentation.

**Key Operational and Business Metrics**

In addition to the measures presented in our condensed consolidated financial statements, we review the following key business metrics to measure our performance, identify trends affecting our business, formulate business plans, and make strategic decisions that will impact the future operational results of New LanzaTech. Increases or decreases in our key business metrics may not correspond with increases or decreases in our revenue.

**Components of Operating Results**

While we have offerings in multiple market segments and operate in multiple countries, we operate and manage our business as one reportable operating segment. Nearly all of our service offerings are delivered and supported on a global basis. Additionally, most of our service offerings are deployed in a nearly identical way, and we evaluate our financial information and resources and assesses the performance of these resources on a consolidated basis.

***Revenues***

To date, we have financed our operations primarily through equity financing, joint development R&D agreements, U.S. government R&D contracts, engineering and other services contracts, licensing agreements, and joint venture agreements. We derive all revenues from a single operating segment. Revenues can be viewed as a combination of the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Feasibility studies and engineering services related to basic design of commercial plants utilizing our technologies;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Licensing of intellectual property when customers deploy our carbon capture and transformation technology;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Research and development services related to novel technologies and microbial strains; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Sale of CarbonSmart ethanol to customers.

------

<u>[**Table of Contents**](#ib82e114cd19f45afae73e7a64e42f208_1390)</u>

Revenue is measured based on the consideration specified in customer contracts and excludes amounts collected on behalf of third parties.

*Carbon Capture and Transformation*

We provide feasibility studies and basic design and engineering services used for detailed design, procurement, and construction of commercial plants that utilize our technologies, along with the sale of equipment and microbes. The services provided are recognized as a performance obligation satisfied over time. Revenue is recognized using the output method based on milestone completion, the cost-to-cost input method for certain engineering services, or the percentage of completion method when certain revenue recognition requirements are met. Management has determined that the milestone completion and the associated contractual payment amounts are an appropriate measure of progress toward complete satisfaction of the performance obligations under Accounting Standards Codification ("ASC") 606, *Revenue from Contracts with Customers* ("ASC 606").

We license intellectual property to generate recurring revenue when our customers deploy carbon capture and transformation plants. When licenses are considered to be distinct performance obligations, the recognition of revenue is dependent on the terms of the contract, which may include fixed consideration or royalties based on sales or usage, in which case, the revenue is recognized when the subsequent sale or usage occurs or when the performance obligation to which some or all of the sales or usage-based royalty is allocated or has been satisfied, whichever is later.

*Research and Development Services*

We perform R&D services related to novel technologies and the development of biocatalysts for commercial applications, mainly to produce fuels and chemicals. We engage in two main types of R&D services – joint development agreements, and other contract research, including projects with the U.S. Department of Energy. Such services are recognized as a performance obligation satisfied over time. Revenue is recognized based on milestone completion, when payments are contingent upon the achievement of such milestones, or based on stage of contract or phase completion method when enforceable rights to payment exist. When no milestones or stages are clearly defined, management has determined that the cost incurred, input method, is an appropriate measure of progress toward complete satisfaction of the performance obligations under ASC 606 and estimates its variable consideration under the expected value method. Accordingly, we record a contract liability for these performance obligations based on milestones achieved and the expected repayment of the development costs.

Revenue is not recognized in advance of customer acceptance of a milestone, when such acceptance is contractually required. Payments for R&D services with no contractual payments are not due from customers until a technical report is submitted; therefore, a contract asset is recognized at milestone completion but prior to the submission of a technical report. The contract asset represents our right to consideration for the services performed at milestone completion. Occasionally, customers provide payments in advance of us providing services which creates a contract liability for the Company. The contract liability represents our obligation to provide services to a customer.

***Collaboration Arrangements***

We have certain partnership agreements that are within the scope of ASC 808, *Collaborative Arrangements* ("ASC 808"), which provides guidance on the presentation and disclosure of collaborative arrangements. Generally, the classification of the transactions as collaborative arrangements is determined based on the nature of the contractual terms of the arrangement, along with the nature of the operations of the participants. Our collaborative agreements generally include provision of R&D services related to novel technologies and biocatalysts. Amounts received for these services are classified as Revenue from collaborative arrangements in the consolidated statements of operations and comprehensive loss. New LanzaTech's R&D services are a major part of our ongoing operations and therefore ASC 606 was applied to recognize revenue.

------

<u>[**Table of Contents**](#ib82e114cd19f45afae73e7a64e42f208_1390)</u>

***Cost of Revenues***

Our R&D, engineering, and other direct costs of services are related to revenue agreements with customers, related parties, and collaborative partners, and represent cost of revenue. Costs include both internal and third-party fixed and variable costs and include materials, supplies, labor, and fringe benefits.

***Research and Development Expenses***

R&D expenses consist of personnel costs and the cost of consultants, materials and supplies associated with R&D projects as well as various laboratory studies. Indirect R&D costs include depreciation and other indirect overhead expenses. We expect our R&D activities to increase substantially as we continue to invest in improving our technology and developing new products.

***Selling, General and Administrative Expenses***

Selling, general and administrative expenses ("SG&A") consist primarily of personnel costs, costs of general marketing activities and promotional activities, travel-related expenses, and other indirect overhead costs. We expect that our sales and marketing expenses will increase as we expand our sales and marketing efforts, commercial capability, brand awareness and customer base through targeted marketing initiatives.

Our general and administrative expenses consist primarily of personnel costs for our executive, finance, corporate and other administrative functions, intellectual property and patent costs, facilities and other allocated expenses, other expenses for outside professional services, including legal, human resources, audit and accounting services and insurance costs. We expect our general and administrative expenses to increase as a result of operating as a public company, including additional costs relating to compliance with the rules and regulations of the SEC and stock exchange rules, legal and auditing services, additional insurance, investor relations activities, and other administrative and professional services. We also expect our intellectual property expenses to increase as we expand and increase protection of our intellectual property portfolio.

***Other (Expense) Income, Net***

Other (expense) income, net relates to miscellaneous other income and expense and foreign currency gains and losses. Interest income consists of income earned from our cash, cash equivalents and short-term investments. We expect our interest income to increase following completion of the Business Combination as we invest the net proceeds in a variety of capital preservation investments, including short-term, investment-grade, interest-bearing obligations of the U.S. government and its agencies.

***Gain from Equity Investees, Net***

We hold interests in LanzaJet located in the United States, and the Shougang Joint Venture located in China, which we have determined to be VIEs for which it has been determined we are not the primary beneficiary. Our variable interests primarily relate to entities in which we have a non-controlling equity interest. Although these financial arrangements resulted in holding variable interests in these entities, they did not empower us to direct the activities of the VIEs that most significantly impact the VIEs' economic performance. However, through our holdings in LanzaJet, our representation on the board of directors and participation in the policy-making process, as well as the material intra-entity transactions, we have determined that we can exercise significant influence over the activities of LanzaJet. Our interest in LanzaJet is accounted for under the equity method of accounting, with income (loss) from equity method investees, net recognized in our consolidated statements of operations and comprehensive loss and equity method investments recognized on our consolidated balance sheets. As of September 30, 2022, we no longer have significant influence over the activities of the Shougang Joint Venture and as a result, our investment is accounted for at cost with impairment (if any) recognized in our consolidated statements of operations and comprehensive loss.

The Company currently has a license agreement with *the Shougang Joint Venture* and a letter agreement with *the Shougang Joint Venture* and Sinopec. These agreements do not provide LanzaTech with the power to direct the

------

<u>[**Table of Contents**](#ib82e114cd19f45afae73e7a64e42f208_1390)</u>

activities that are most significant to the economic performance of these entities, therefore LanzaTech has determined it is not the primary beneficiary and does not currently consolidate any VIEs.

***Income Tax Expense (Benefit)***

Current and deferred taxes are calculated based on tax rates enacted or substantively enacted at the reporting date and are recognized in profit or loss except when the tax relates to items charged or credited to other comprehensive income, in which case the tax is also recognized in other comprehensive income. Deferred tax is recognized in respect of temporary differences arising between the tax bases of assets and liabilities and their carrying amounts in the financial statements. Deferred tax assets and unused tax losses are only recognized to the extent that it is probable that future taxable amounts will be available to utilize temporary differences and losses. These losses are subject to shareholder continuity rules, and may be impacted by future fundraising activities.

We maintain a valuation allowance against the full value of our net deferred tax assets because management believes the recoverability of the tax assets is not more likely than not.

***Revenue***

Total revenue increased $7.5 million, or 41%, in the first nine months of 2022 compared to the same period in 2021. Engineering and other services increased revenues by $7.9 million, consisting of an increase of $1.2 million from projects with new customers and a $6.7 million increase from contracts with existing customers. Revenue from the sale of CarbonSmart ethanol generated an increase in revenues of $3.4 million, revenue from other contract research increased revenues by $2.7 million and revenue from licensing increased revenues by $0.1 million. This increase in revenue was partially offset by a decrease of $(6.6) million in revenue from joint development agreements as a result of the completion and near-completion of certain joint development projects.

***Cost of Revenues***

Cost of revenue increased $9.2 million, or 93%, in the first nine months of 2022 compared to the same period in 2021. Cost of revenue from engineering and other services increased by $8.0 million mainly due to an increase in the number of customer projects and a shift in sales mix with certain projects generating higher cost of revenue. Additional changes in cost of revenue resulted from increases in CarbonSmart ethanol sales which generated $2.9 million in cost of revenue and increases in cost of revenue of $1.7 million from other contract research. These increases were partially offset by decreases of $(3.4) million of cost of revenue from joint development agreements.

***Research and Development***

R&D expense increased $10.6 million, or 36%, in the first nine months of 2022 compared to the same period in 2021. This was due to an increase of $5.1 million in headcount and related costs to accelerate growth, a $2.3 million increase in general R&D spend, and an increase of $3.2 million in external R&D services to expand R&D capabilities.

***Selling, General and Administrative Expense***

SG&A expense increased $7.9 million, or 68%, in the first nine months of 2022 as compared to the same period in 2021. The increase was primarily related to a $4.6 million increase in personnel costs as we scaled up non-R&D-related functions, and a $3.3 million increase in external consulting fees related to the proposed Business Combination. See Note 1 to our condensed consolidated financial statements included elsewhere in this prospectus for more information regarding the proposed Business Combination.

***Gain from Equity Method Investees, Net***

In the first nine months of 2022, gain from equity method investees, net remained relatively consistent with the same period in 2021, primarily due to net loss attributable to Legacy LanzaTech of $1.1 million for each of the nine month periods ended September 30, 2022 and September 30, 2021, offset by gain from the dilution of our equity method interests of $3.4 million for the nine months ended September 30, 2022, and $3.5 million for the nine months ended September 30, 2021.

***Revenue***

Total revenue increased $7.1 million, or 39%, in the year ended December 31, 2021 compared to the year ended December 31, 2020. During the year ended December 31, 2021, the net impact of joint development agreements increased revenues by $4.8 million due to $1.5 million in collaborative arrangements from new customers and $3.3 million in continued collaborations with existing customers.Other contract research increased by $0.2 million. Engineering and other services increased revenues by $1.1 million, primarily due to an increase in the number of customers and revenue-generating projects net of a decrease of $(1.9) million due to a reduction in the volume of services provided to LanzaJet. Revenue from licensing from related parties increased by $1.0 million for the year ended December 31, 2021.

***Cost of Revenues***

Cost of revenue increased $3.6 million, or 31%, in the year ended December 31, 2021, compared to December 31, 2020. This increase is in line with the increase in revenues: cost of revenue from engineering and other services increased by $1.6 million mainly due to an increase in the number of customers, net of a decrease of $(1.9) million in cost of revenue for engineering services with a related party. Cost of revenue from joint development agreements increased by $2.0 million due to continuing collaboration with existing customers.

***Research and Development***

R&D expense increased $9.8 million, or 28%, in the year ended December 31, 2021 compared to the year ended December 31, 2020. The increase in R&D expense, in the year ended December 31, 2021 was due to an increase of $5.9 million in personnel and related costs to accelerate growth, a $1.8 million increase in general R&D spend from 2020 when COVID-19 lockdowns halted R&D, an increase of $1.4 million in external R&D services, and an increase of $0.7 million to expand R&D capabilities.

***Selling, General and Administrative Expense***

SG&A expense increased $4.2 million, or 46%, in the year ended December 31, 2021, compared to the year ended December 31, 2020. The increase in SG&A expense was primarily related to a $1.8 million increase in personnel costs as we scaled up non-R&D-related functions and a $1.2 million increase in external consulting fees related to the proposed Business Combination. See Note 20 to our consolidated financial statements included elsewhere in this prospectus for more information regarding the proposed Business Combination. The remaining increase of $1.2 million in SG&A expense is related to various other non-R&D services.

***Other Income (Expense), Net***

The following table shows our other income (expense), net for the years ended December 31, 2021, and 2020, and related period-over-period changes:

---

| | | | | |
|:---|:---|:---|:---|:---|
|  | **Year ended December 31,** | **Year ended December 31,** | **Change** | **Change** |
| **(In thousands, except for percentages)** | **2021** | **2020** | **2021 vs. 2020** | **2021 vs. 2020** |
| Interest expense, net | $(7) | $(351) | $344 | (98)% |
| Gain on extinguishment of debt | 3065 |  | 3065 | 100% |
| Other (expense) income, net | (673) | 172 | (845) | (491)% |
| &nbsp;&nbsp;&nbsp;&nbsp;Total other income (expense), net | $2385 | $(179) | $2564 | (1432)% |

---

Other income (expense), net increased $2.6 million, or (1,432)%, in the year ended December 31, 2021 compared to the year ended December 31, 2020. The increase is primarily due to the forgiveness of $3.1 million in principal outstanding under the PPP Loan (as defined below) and a decrease in interest expense of $0.3 million, partially offset by a $(0.7) million fluctuation, year-over-year, in the change in fair value of the warrant liability and a $(0.1) million increase in foreign exchange losses.

***Gain from Equity Method Investees, Net***

In 2021 compared to 2020, gain from equity method investees, net decreased $(0.2) million, or (10)%, primarily due to lower gain from the dilution of our equity method interests recognized in the year ended December 31, 2021, as compared to the year ended December 31, 2020, partially offset by lower losses incurred by the two equity method investees during 2021, as compared to 2020, as they continued to scale up operations.

**Liquidity and Capital Resources**

***Cash and Cash Equivalents***

Cash and cash equivalents comprise cash on hand, demand deposits at banks, and other short-term, highly liquid investments with original maturity of three months or less that are readily convertible to known amounts of cash and which are subject to an insignificant risk of changes in value. The following table shows the balances of our cash, cash equivalents and restricted cash as of September 30, 2022 and September 30, 2021:

<u>[**Table of Contents**](#ib82e114cd19f45afae73e7a64e42f208_1390)</u>

As of September 30, 2022 as compared to September 30, 2021, Legacy LanzaTech's cash, cash equivalents, and restricted cash decreased $(64.7) million, or (56)%, primarily due to increased cash used to fund working capital and an increase in the net loss adjusted for non-cash charges, partially offset by the proceeds from the issuance of a $30.0 million SAFE and warrant instruments in December 2021.

The following table shows balances of our cash and cash equivalents as of December 31, 2021, and 2020:

| Total cash, cash equivalents, and restricted cash | $128732 | $60909 | $67823 | 111% |

---

As of December 31, 2021 as compared to December 30, 2020, Legacy LanzaTech's cash, cash equivalents, and restricted cash increased $67.8 million, or 111%, primarily due to the proceeds from the issuance of equity instruments of Legacy LanzaTech and the proceeds from the issuance of the SAFE and warrant instruments, partially offset by the cash used to fund operations.

***Sources and Uses of Capital***

Since inception, we have financed our operations primarily through equity financing, joint development R&D agreements, U.S. government R&D contracts, engineering and other services contracts, licensing agreements, and joint venture agreements.

Our ability to successfully develop products and expand our business depends on many factors, including our ability to meet working capital needs, the availability of equity or debt financing and, over time, our ability to generate cash flows from operations. We manage our capital to ensure that LanzaTech can continue as a going concern while maximizing the return to stakeholders through the optimization of debt and equity balances. Our overall capital risk strategy remains unchanged from prior years. Following completion of the Business Combination, the Company may change its capital risk strategy related to use of capital proceeds from the Business Combination to increase its product offerings or for business growth purposes.

As of September 30, 2022, our capital structure consists of equity (comprising issued capital, reserves and accumulated deficit). We are not subject to any externally imposed capital requirements.

LanzaTech had six outstanding series of redeemable preferred stock. LanzaTech preferred shares were convertible at the holder's option into shares of common stock, on a share-for-share basis, using a conversion rate determined by dividing the original issue price by the conversion price. Each LanzaTech preferred share was automatically converted into a common share of LanzaTech upon the closing of the Business Combination. In April 2021, Legacy LanzaTech issued 3,634,210 Series F preferred shares for gross proceeds of $83.1 million ($22.86 per share).

On October 2, 2022, LanzaTech entered in the Brookfield SAFE with Brookfield and received a cash payment of $50,000,000 as the Initial Purchase Amount. In exchange, the Company granted to Brookfield the right to certain shares of the Company's capital stock upon a Liquidity Event. If no Liquidity Event occurs beforehand, on the fifth anniversary of the Brookfield SAFE, LanzaTech will repay in cash any remaining unconverted portion of the Initial Purchase Amount less any Non-Repayable Amount, plus interest in the high single digits, compounded annually. Brookfield has the option to extend the repayment date to the tenth anniversary of the date of the Brookfield SAFE if certain events do not occur.

Regarding indebtedness, LanzaTech does not have any outstanding debt on its condensed consolidated balance sheet as of September 30, 2022. During fiscal year 2021, LanzaTech repaid the outstanding amount of $(0.6) million of its loan facility with Venture Lending and Leasing VII Inc. and Venture Lending and Leasing VIII, Inc. Additionally, LanzaTech's $3.1 million Paycheck Protection Program loan (the "PPP Loan") outstanding as of December 31, 2020 was fully forgiven by the Small Business Administration in September 2021. Consequently, LanzaTech recognized a gain on debt extinguishment of $(3.1) million related to the PPP Loan, in other income in the statement of operations and comprehensive loss for the year ended December 31, 2021.

<u>[**Table of Contents**](#ib82e114cd19f45afae73e7a64e42f208_1390)</u>

On November 9, 2022, LanzaTech committed to purchase $5.5 million of Subordinated Secured Notes in a funding for LanzaJet's subsidiary, FPF, expected to occur on May 1, 2023. The Subordinated Secured Notes are secured by a security interest over the intellectual property owned or in-licensed by LanzaJet. LanzaJet also provides a guarantee of any costs and expenses required to complete the initial facility and achieve commercial operation.

In the normal course of our business, we also enter into purchase commitments or other transactions in which we make representations and warranties that relate to the performance of our goods and services. We do not expect material losses related to these transactions.

We believe our existing cash and cash equivalents will be sufficient to fund our operations for at least the next 12 months from the date of this prospectus. However, our liquidity assumptions may prove to be incorrect, and we could utilize our available financial resources sooner than we currently expect. In addition, we may elect to raise funds within this period of time through equity or debt financing arrangements or collaborations. Our future capital requirements and the adequacy of available funds will depend on many factors, including those set forth under "Risk Factors" elsewhere in this prospectus.

We will receive up to an aggregate of approximately $145 million from the exercise of all of the warrants and AM Warrant, assuming the exercise in full of all of the warrants and the AM Warrant for cash. However, if the market price for shares of common stock is less than the exercise price of a holder's warrant or AM Warrant, as applicable, such holder may be less likely to exercise the warrants as such holder would be selling at a loss if they sold their common stock. Subject to adjustment, the exercise price of the warrants is $11.50 per share and the exercise price of the AM Warrant is $10.00 per share. On February 10, 2023 the last reported sales price of the common stock was $7.30 per share. Additionally, if the market price for shares of common stock is less than $10.00 per share, holders of shares of common stock would be selling at a loss if they purchased the shares of common stock at $10.00 per share. Because certain selling stockholders purchased shares privately at a price below the current market price, they may have an incentive to sell shares of their common stock because they could profit despite the market price of common stock falling below $10.00 per share. While these selling stockholders may, on average, experience a positive rate of return based on the current market price, public securityholders may not experience a similar rate of return on the securities they purchased due to differences in the purchase prices and the current market price. For example, based on the closing price of our common stock of $7.30 on February 10, 2023, the Sponsor and the AMCI Insiders would have a potential profit of up to approximately $7.295 per share that they purchased prior to the initial public offering of AMCI, or up to approximately $14.8 million in the aggregate (not giving effect to the issuance of common stock issuable upon exercise of the warrants held by them).

We may not be able to secure additional financing to meet our operating requirements on acceptable terms, or at all. If we raise additional funds by issuing equity and/or convertible debt securities, dilution to our existing stockholders will result. If we raise additional financing and incur indebtedness, we would be subject to increased fixed payment obligations and could also be subject to certain restrictive covenants, such as limitations on our ability to incur additional debt, limitations on our ability to acquire, sell or license intellectual property rights and other operating restrictions that could adversely impact our ability to conduct our business. If we are unable to obtain additional funds, we will have to reduce our operating costs, which will cause a delay or reduction in our technology development and commercialization programs.

The common stock and the common stock issuable upon exercise of the resale securities noted above represent a substantial percentage of the total outstanding shares of our common stock as of the date of this prospectus. Additionally, if all of the Convertible Securities were converted, the selling stockholders would own 198,818,523 shares of common stock, representing approximately 92.3% of the total outstanding common stock. So long as the registration statement of which this prospectus forms a part is effective, the sales of the securities being offered in this prospectus could result in a significant decline in the public trading price of the common stock.

***Cash Flows Used in Operating Activities***

For the nine months ended September 30, 2022, net cash used in operating activities was $(71.3) million. This was primarily driven by a net loss of $(55.0) million, adjusted for share-based compensation expense of $2.1 million, depreciation of property, plant and equipment of $3.4 million, and non-cash lease expense of $1.3 million. Additional contributions of the net cash usage are related to the decrease in net cash provided by operating assets and liabilities of $(20.2) million, the non-cash gain from equity method investees, net of $(2.3) million, the gain on change in fair value of warrant liabilities of $(0.3) million, the non-cash recognition of licensing revenue of $(1.6) million and non-cash foreign currency exchange losses of $1.3 million.

For the nine months ended September 30, 2021, net cash used in operating activities was $(26.7) million. This was primarily driven by a net loss of $(30.6) million, adjusted for net cash provided by operating assets and liabilities of $4.3 million, share-based compensation expense of $1.8 million, depreciation of property, plant and equipment of $2.8 million, loss on change in fair value of warrant liabilities of $0.7 million, and non-cash lease expense of $1.2 million. This was partially offset by non-cash recognition of licensing revenue of $(1.5) million, the forgiveness of LanzaTech's $(3.1) million aggregate principal amount PPP Loan, and the gain from equity method investees, net of $(2.4) million.

***Cash Flows Used in Investing Activities***

For the nine months ended September 30, 2022, net cash used in investing activities was $(6.5) million, driven by the purchase of property, plant and equipment of $(6.5) million.

For the nine months ended September 30, 2021, net cash used in investing activities was $(4.2) million, driven by the purchase of property, plant and equipment of $(4.2) million.

***Cash Flows from Financing Activities***

For the nine months ended September 30, 2022, net cash provided by financing activities was not significant.

For the nine months ended September 30, 2021, net cash provided by financing activities was $86.0 million. This was driven by $83.1 million in proceeds from the issuance of equity instruments of LanzaTech, proceeds of $0.7 million from the exercise of options to acquire shares of common stock of LanzaTech, and the proceeds from the exercise of warrants of $3.2 million. This was partially offset by the repayment of borrowings of $(0.6) million and the repurchase of equity instruments of LanzaTech of $(0.4) million.

**Off-Balance Sheet Arrangements**

As of September 30, 2022 and December 31, 2021, we did not engage in any off-balance sheet arrangements, including the use of structured finance, special purpose entities or variable interest entities.

**Critical Accounting Policies and Significant Management Estimates**

Our management's discussion and analysis of our financial condition and results of operations is based on our consolidated financial statements included elsewhere in this prospectus that have been prepared in accordance with US GAAP. The preparation of these financial statements requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, expenses, and related disclosures. We consider an accounting estimate to be critical to the consolidated financial statements if the estimate is complex in nature or requires a high degree of judgment and actual results may differ from these estimates with any such differences being potentially material. Our estimates are based on our historical experience and on various other factors that we believe are reasonable under the circumstances. We evaluate our estimates and assumptions on an ongoing basis. While our significant accounting policies are more fully described in Note 2 to our consolidated financial statements, we believe that the accounting policies discussed below are critical to understanding our historical and future performance:

***Revenue Recognition***

We recognize revenue from our contracts with customers in accordance with ASC 606. The Company also has certain partnership agreements that are within the scope of ASC 808. We primarily earn revenue from services related to feasibility studies and basic engineering design of commercial plants, joint development, and contract R&D activities to develop novel biocatalysts and related technologies. When accounting for these arrangements, we must develop assumptions that require judgment such as determining the performance obligations in the contract, determining the transaction price for the contract and stand-alone selling price for each performance obligation identified, and measuring progress towards satisfaction of the performance obligations.

The determination of whether goods and services qualify as distinct performance obligations is based on the contract terms and our view of the business. Typically, our goods and services provided under a contract with a customer are viewed as a single performance obligation. Most of our arrangements provide fixed consideration, however, when there are variable consideration elements, we estimate the transaction price and whether revenue should be constrained. Significant estimates and judgments are also used when a material right is provided to the customer. In these instances, management estimates the stand-alone selling price and apportions the total transaction price to this material right.

Most performance obligations on our non-governmental arrangements are recognized over time. We typically use the output method to measure the satisfaction of such performance based on milestone completion or percentage completion when certain revenue recognition requirements are met. We exercise judgment when determining the percentage of completion against the total transaction price initially estimated. For arrangements with government agencies, we measure the satisfaction of performance obligations over time using the input method which requires judgment when selecting the most indicative measure of such performance.

***Stock-Based Compensation***

We measure stock-based awards granted to employees and directors based on their fair value on the date of grant. We have elected not to estimate forfeitures which means compensation expenses may be reversed in the period in which the forfeiture occurs.

We mostly apply judgment for stock-based awards with performance conditions, because compensation expense is recognized only when it is probable the performance conditions will be met (i.e. occurrence of a liquidity event). Management determined that the occurrence of the liquidity event is probable when the event is consummated, as such, no compensation expenses have been recognized.

------

<u>[**Table of Contents**](#ib82e114cd19f45afae73e7a64e42f208_1390)</u>

We estimate the fair value of each stock option grant on the date of grant using the Black-Scholes option-pricing model, which requires the use of highly subjective assumptions including:

Expected Term - We have opted to use the "simplified method" for estimating the expected term of plain-vanilla options, whereby the expected term equals the arithmetic average of the vesting term and LanzaTech's contractual term of the option (generally 10 years).

Risk-Free Interest Rate - The risk-free rate assumption is based on the U.S. Treasury zero-coupon instruments with maturities similar to the expected term of LanzaTech's stock options.

Expected Dividend - We have not issued any dividends and do not anticipate issuing dividends on LanzaTech's common stock. As a result, we have estimated the dividend yield to be zero.

Expected Volatility - Due to our limited operating history and a lack of company-specific historical and implied volatility data, we have based our estimate of expected volatility on the historical volatility of a group of similar companies that are publicly traded. The historical volatility data was computed using the daily closing prices for the various companies' shares during the equivalent period of the calculated expected term of the stock-based awards.

We estimate the fair value of the RSAs using the fair value of common stock. Please refer to the Common Stock Valuation section below.

***Warrant Liabilities***

Warrants to purchase shares of redeemable convertible preferred stock are classified as liabilities under Other accrued liabilities and under SAFE warrant on our consolidated balance sheets. These warrants are recognized at fair value with subsequent changes recorded in other income (expense), net, in the statements of operations and comprehensive loss. We will continue to adjust for changes in fair value until the earlier of the exercise of the warrants, at which time the liability will be reclassified as redeemable convertible preferred stock, or the expiration of the warrants, at which time the entire amount will be reversed and reflected in the statements of operations and comprehensive loss.

We utilized the Black-Scholes option-pricing model, which incorporates management's assumptions and estimates, to value the preferred stock warrants. Estimates and assumptions impacting the fair value measurement include the fair value per share of the underlying redeemable convertible preferred stock, the remaining contractual term of the warrants, risk-free interest rate, expected dividend yield and expected volatility of the price of the underlying preferred stock. We determined the fair value per share of the underlying preferred stock by taking into consideration our most recent issuance of our preferred stock with additional factors deemed relevant, because we are a private company and lack company-specific historical and implied volatility information of our stock. We determined the remaining contractual term based on the contract term of the warrants adjusted for the probability of a liquidity event. Expected stock volatility was based on the historical volatility of publicly traded peer companies for a similar remaining contractual term.

***Common Stock Valuation***

As there has been no public market for our equity instruments to date, the estimated fair value of our shares of common stock has been determined by management and approved by the LanzaTech Board as of the grant date. The LanzaTech Board considered our most recently available independent third-party valuation of the common stock and additional objective and subjective factors that it believed were relevant at the date of the grant.

The independent third-party valuations of the common stock have been performed in accordance with the guidance outlined in the AICPA Practice Aid, Valuation of Privately-Held Company Equity Securities Issued as Compensation ("AICPA's Practice Aid"). The specialist considered all objective and subjective factors, including management's best estimate of our business condition, prospects, and operating performance at each valuation date. Other significant factors included:

------

<u>[**Table of Contents**](#ib82e114cd19f45afae73e7a64e42f208_1390)</u>

the rights, preferences, and privileges of our preferred stock as compared to those of the common stock, including the liquidation preferences of our preferred stock;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our results of operations, and financial position;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• arms-length transactions involving recent rounds of preferred stock financings;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the lack of liquidity of the common stock;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our stage of development and business strategy and the material risks related to our business and industry;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the valuation of publicly traded companies in relevant industry sectors, as well as recently completed mergers and acquisitions of peer companies;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the likelihood of achieving a liquidity event, such as an initial public offering or a sale of our company, given prevailing market conditions; and

In valuing the common stock, the fair value of our business was determined using an option pricing model to backsolve the value of the security from our most recent round of financing which implies a total equity value as well as a per-share common stock value at the valuation date. In August 2021, LanzaTech used a weighted-average methodology for valuing its common stock that included a probability-adjusted liquidity event.

Following the Business Combination, the fair market value of the common stock will be determined based on the quoted market price of the common stock.

***Income Taxes***

New LanzaTech is subject to the income tax laws in the jurisdictions in which we operate. New LanzaTech makes significant estimates and judgments to determine the provision for income taxes, taxes payables, and deferred tax assets and liabilities. We record a valuation allowance to reduce deferred tax assets to the amount that is more likely than not to be realized. The ability to realize deferred tax assets depends on our ability to generate sufficient taxable income within the carryback or carryforward periods provided for in the tax law for each tax jurisdiction. In determining whether deferred tax asset can be realized based on the provisions of the applicable accounting guidance, management considers the historical operating results, known or planned operating developments, the period of time over which certain temporary differences will reverse, consideration of the utilization of certain deferred income tax liabilities, tax law carryback capability in a particular country, prudent and feasible tax planning strategies, changes in tax laws, and estimates of future earnings and taxable income.

We record uncertain tax positions on the basis of a two-step process whereby it is determined whether it is more likely than not that the tax positions will be sustained based on the technical merits of the position, and for those tax positions that meet the more likely than not criteria, the largest amount of tax benefit that is greater than 50% likely to be realized upon ultimate settlement with the related tax authority is recognized. The Company evaluates and adjusts the amount of unrecognized income tax benefits based on changes in law, facts and circumstances.

**Emerging Growth Company Status**

Section 102(b)(1) of the JOBS Act exempts "emerging growth companies" (as defined in Section 2(a) of the Securities Act) from being required to comply with new or revised financial accounting standards until private companies are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can choose not to take advantage of the extended transition period and comply with the requirements that apply to non-emerging growth companies, but any such election to not take advantage of the extended transition period is irrevocable. New LanzaTech has elected not to opt out of the extended transition period for new or revised financial accounting standards. This may make it difficult or impossible to compare New LanzaTech's financial results with the financial results of another public company that is either not an emerging growth company or is an emerging growth company that has chosen not to take advantage of the extended transition period exemptions because of the potential differences in accounting standards used.

------

<u>[**Table of Contents**](#ib82e114cd19f45afae73e7a64e42f208_1390)</u>

New LanzaTech will remain an emerging growth company until the earliest of (i) the last day of the fiscal year in which the market value of common stock that is held by non-affiliates equals or exceeds $700 million as of the end of that year's second fiscal quarter, (ii) the last day of the fiscal year in which New LanzaTech has total annual gross revenue of $1.235 billion or more during such fiscal year (as indexed for inflation), (iii) the date on which New LanzaTech has issued more than $1 billion in non-convertible debt in the prior three-year period or (iv) December 31, 2026, which is the last day of the fiscal year following the fifth anniversary of AMCI's IPO.

**Implications of being a Smaller Reporting Company**

Additionally, New LanzaTech is a "smaller reporting company" as defined in Item 10(f)(1) of Regulation S-K. Smaller reporting companies may take advantage of certain reduced disclosure obligations, including, among other things, providing only two years of audited financial statements. New LanzaTech will remain a smaller reporting company until the last day of the fiscal year in which (i) the market value of common stock held by non-affiliates exceeds $250 million as of the end of that year's second fiscal quarter, or (ii) New LanzaTech's annual revenues exceeded $100 million during such completed fiscal year and the market value of common stock held by non-affiliates equals or exceeds $700 million as of the end of that year's second fiscal quarter. To the extent New LanzaTech takes advantage of such reduced disclosure obligations, it may also make comparison of its financial statements with other public companies difficult or impossible.

**Recently Issued and Adopted Accounting Standards**

See Note 2 to our condensed consolidated financial statements, included elsewhere in this prospectus, for a full description of recent accounting pronouncements, including the actual and expected dates of adoption and estimate effects on our consolidated results of operations and financial condition, which is incorporated herein by reference.

**Non-GAAP Financial Measures**

To supplement our financial statements presented in accordance with US GAAP and to provide investors with additional information regarding our financial results, we have presented in this prospectus adjusted EBITDA, a non-GAAP financial measure. Adjusted EBITDA is not based on any standardized methodology prescribed by US GAAP and is not necessarily comparable to similarly titled measures presented by other companies.

We define adjusted EBITDA as our net loss, excluding the impact of depreciation and amortization, interest income (expense), income tax benefit (expense), gain on extinguishment of debt, stock-based compensation, and loss/(gain) from equity method investees. We monitor and have presented in this prospectus adjusted EBITDA because it is a key measure used by our management and the Board to understand and evaluate our operating performance, to establish budgets, and to develop operational goals for managing our business. We believe adjusted EBITDA helps identify underlying trends in our business that could otherwise be masked by the effect of certain expenses that we include in net loss. Accordingly, we believe adjusted EBITDA provides useful information to investors, analysts, and others in understanding and evaluating our operating results and enhancing the overall understanding of our past performance and future prospects.

Adjusted EBITDA is not prepared in accordance with US GAAP and should not be considered in isolation of, or as an alternative to, measures prepared in accordance with US GAAP. There are a number of limitations related to the use of adjusted EBITDA rather than net loss, which is the most directly comparable financial measure calculated and presented in accordance with US GAAP. For example, adjusted EBITDA: (i) excludes stock-based compensation expense as it recently has been, and will continue to be for the foreseeable future, an excess significant non-cash expense for our business beyond our normative operating environment in consideration of the proposed Business Combination and subsequent transition to a publicly-traded company; (ii) excludes depreciation expense and, although this is a non-cash expense, the assets being depreciated and amortized may have to be replaced in the future; and (iii) does not reflect the cash requirements necessary to service interest on our debt, which affects the cash available to us; and (iv) certain income or expense items that do not provide a comparable measure of our business performance. In addition, the expenses and other items that we exclude in our calculations of adjusted EBITDA may differ from the expenses and other items, if any, that other companies may exclude from adjusted EBITDA when they report their operating results. In addition, other companies may use other measures to

------

<u>[**Table of Contents**](#ib82e114cd19f45afae73e7a64e42f208_1390)</u>

evaluate their performance, all of which could reduce the usefulness of our non-GAAP financial measures as tools for comparison.

The following table reconciles adjusted EBITDA to net loss, the most directly comparable financial measure calculated and presented in accordance with US GAAP.

**BUSINESS**

**Business Overview** 

Founded in 2005 in New Zealand and headquartered today in Skokie, Illinois, we are a nature-based carbon refining company that transforms waste carbon into the chemical building blocks for consumer goods such as sustainable fuels, fabrics, and packaging that people use in their daily lives. Our goal is to reduce the need for virgin fossil fuels by challenging and striving to change the way the world uses carbon. We aim to accomplish this through the creation of a circular economy where carbon can be reused rather than wasted. Through technology and applications that are designed to touch multiple points of carbon use such as converting industrial, municipal, and agricultural waste into products, developing sustainable products to change the supply chain, and having systems to reuse the waste once consumers are done with the products, we believe we can offer a solution to help alleviate the global carbon crisis. Our economically viable and scalable technology is designed to enable emitters to reduce their environmental impact and potentially to replace materials made from virgin fossil resources with recycled carbon, supporting their climate goals, meeting mandated targets, and creating a more sustainable future.

Using our process technology, our partners launched the world's first commercial carbon refining plant in 2018 in China and have subsequently added two commercial plants operating in China. LanzaTech has numerous projects in construction, under development and in the pipeline globally. Our technology platform is designed to use a variety of waste feedstocks, from waste industrial gases to biomass residues and municipal solid waste. Our technology platform is designed to capitalize on the demand for sustainable fuels and chemicals, which can be used in multiple sectors such as aviation, automotive, textiles, home goods, consumer goods and others, to address the growing preference among major companies for environmentally conscious products and manufacturing processes. We believe LanzaTech's proven commercialized technology can enable global scale decarbonization and initiate a circular and climate positive carbon economy.

Gas fermentation is a robust form of carbon capture and transformation that enhances the value of waste streams and reduces environmental pollution. Additionally, our technology platform utilizes existing industrial land and recycled process water, further reducing the environmental impact of producing our low carbon ethanol on land and biodiversity. Gas fermentation is a key part of our technology offering and we license this capability to customers to develop their own gas fermentation facilities, accelerating the spread of our technology across a variety of feedstocks and geographies.

Our novel technology platform is like brewing, but instead of using yeast that eat sugar to make alcohol, our biocatalysts, or microbes, eat waste carbon to produce ethanol, ethanol derivatives, and ethanol co-products. Because our system is biological and can grow in dynamic environments and react in real-time to changing conditions, it is much more tolerant of variability in feedstock composition and supply than systems based on catalytic chemistry and is therefore highly customizable.

Our low carbon ethanol is being produced at commercial scale at three separate locations in China, with production of over 50 million gallons of fuel grade ethanol, resulting in the mitigation of over 250,000 tons of CO2 and keeping the equivalent of an estimated 23 million gallons of oil in the ground since May 2018. Used microorganisms from our commercial facilities are protein-rich and can be sold in China as animal feed.

We are also developing biocatalysts and processes to produce a vast suite of additional products utilizing novel biocatalysts, including acetone and isopropanol ("IPA") and important industrial solvents used in multiple applications including production of polymers from IPA. Products generated through the application of downstream catalytic chemistry of ethanol include SAF, sustainable diesel, ethylene, polyethylene, polyethylene terephthalate ("PET"), surfactants and glycols. Sustainable diesel can be blended with conventional diesel fuels as "drop in fuel" without any blending wall set by engine technology and offers reduced emissions, improving local air quality. Ethylene is widely used in the chemical industry, mostly for production of polyethylene, a plastic containing polymer chains of ethylene units in various chain lengths. Polyethylene is primarily used to make films and for packaging applications. Ethylene glycol is another product that can be used for production of surfactants, a key ingredient for detergents and liquid soap production. Ethanol can be further converted to monoethylene glycol ("MEG"), an important precursor to PET for use in packaging and textiles applications.

In June 2020, we helped launch LanzaJet, a SAF company, and maintain approximately a 25% ownership stake in the business. LanzaJet has secured funding for a 10 million gallon commercial-scale production facility that we expect will begin producing SAF in 2023. We developed and scaled the production facility in Soperton, Georgia using our platform technology, which enables the conversion of ethanol to sustainable jet and diesel fuels, in collaboration with the Pacific Northwest National Lab and the U.S. Department of Energy. Using our platform technology, we have converted ethanol produced from steel mill emissions to SAF and have powered flights by Virgin Atlantic in 2018 and All Nippon Airways in 2019.

![amci-20230213_g2.jpg](amci-20230213_g2.jpg)

We aim to maximize revenue through the selective deployment of both our licensing and co-development models. Our licensing model focuses on generating licensing, royalty, and services fees from our commercialization efforts, while our partners own and operate the gas fermentation plants. This capital-light model enables us to concurrently partner with a significant number of partners to build customer - owned gas fermentation facilities in parallel, accelerating the spread of our technology platform. Our licensing model typically generates stable, recurring revenues which we anticipate will compound as more customer plants are built and validated by our pipeline of customers. As a licensor and services provider, we structure our agreements to provide engineering and startup services and key components of the overall equipment package that are based on our proprietary designs and integrations. Once fully operational, recurring revenues are generated from royalties on the offtake, ongoing supply of microbes and media, as well as software, monitoring and analytics support. In certain more limited cases, we will act as co-developer on projects, allowing us to leverage our existing relationships and engineering and project development expertise in a financial sponsor role for select projects where we believe we can participate in the ownership, either directly or by arranging and deploying third-party capital, and operation of the gas fermentation plant. In the select instances where we will participate directly in the project ownership, we expect to be a minority investor in those projects' capital requirements, accounting for approximately 5% of the total capital. We believe that the co-development model has the potential to allow for the acceleration of the development and integration of new feedstocks and products while also allowing us to capture additional potential value from the individual project's performance. In each instance of co-development, we intend to license our technology directly to the project, which we expect will enable us to capture the same revenue streams of licensing, royalty, and services fees generated through the licensing model with customer-owned facilities. To maximize revenue from each project, whether via licensing or co-development, we sell supplies and equipment to our projects and customers. Additionally, we provide advisory, research and engineering services to develop new chemicals, use new feedstocks, and advance new fermentation or synthetic biology capabilities.

**Market Opportunity**

***Overview***

GHG emissions are rampant in major economic areas across the globe. In Asia, the largest emitter of GHGs, approximately 10 billion metric tons of CO2 are emitted per year, with almost 30% of the global territorial fossil fuel CO2 emissions occurring in China alone. In the United States, approximately six billion metric tons of CO2 have been emitted annually for over 30 years. In Europe, nearly five billion metric tons of CO2 are emitted per year. GHGs from human activities are the most significant driver of observed climate change, which is taking on greater importance and urgency throughout the world.

In 2016, the Paris Agreement was signed by a consortium of countries committing to limit the increase of global average temperatures to 2°C or less compared to pre-industrial levels. Such initiatives have placed an increased emphasis on monitoring and mitigating the effects of climate change and generally promoting environmentally friendly behavior. In 2017, the International Energy Agency ("IEA") estimated that an annual $3.5 trillion in energy-sector investments would be required through 2050 to achieve the 2°C target. In 2019, the European Union released the Green Deal Communication, a package of measures and policies ranging from ambitiously cutting emissions, to investing in cutting-edge research and innovation, to preserving Europe's natural environment and achieving a carbon neutral economy by 2050. The roadmap includes a comprehensive plan to increase the European Union's GHG reduction target for 2030 to at least 50% and toward 55% as compared to 1990, compared to the current target of 40%. In the United States, President Biden re-committed to the Paris Agreement, pledging 50-52% GHG reductions by 2030 compared to 2005 levels. In 2021, the U.S. Congress passed the Infrastructure Investment and Jobs Act, which included over $62 billion for the U.S. Department of Energy to use for clean energy technology deployment. In August 2021, President Biden signed the Inflation Reduction Act, which provided approximately $369 billion for clean energy deployment and climate change mitigation and adaptation.

Alongside potential government mandates for aviation and industrial emitters, regional governments, companies and investors have announced their own emissions and waste reduction targets. According to the RE100 initiative, nearly 350 global companies spanning a broad array of sectors have pledged to transition to 100% renewable electricity by 2050 with an average target date of 2030. Outside of the RE100, many more companies are facing consumer and shareholder pressure to increase their environmental disclosures and join the transition to cleaner energy sources. For example, the members of the International Air Transport Association, which includes nearly 300 airlines responsible for over 80% of the world's air traffic, have committed to cut their emissions in half by 2050 compared to 2005 levels. In addition, in March 2021, Airlines for America, the industry trade organization representing the leading U.S. airlines, announced the commitment of its member carriers to work to achieve net-zero carbon emissions by 2050. The carriers also committed to work toward a rapid expansion of the production and deployment of commercially viable SAF, specifically to make two billion gallons of SAF available to U.S. aircraft operators in 2030.

We believe that carbon capture and transformation technologies will be used increasingly within industrial sectors of the economy as one of the primary methods to reduce GHG emissions and meet mandates and climate goals. The two options for dealing with captured carbon today are sequestering it in the ground, or carbon capture and sequestration ("CCS"), and recycling it into products, or carbon capture and utilization or transformation ("CCU" or "CCT").

We believe LanzaTech can provide a profitable pathway to solving an emitter's carbon problem. For example, today in Europe, a steel mill can pay penalties for their emissions, purchase offsets, or invest in a CCS facility and reduce their emissions at site under an Emissions Trading System. In each case, we believe the cost of the emissions, offsets or investment in a CCS facility are less cost effective than building a LanzaTech CCT facility to decrease carbon emissions.

While reducing the carbon intensity of fuels is important, it does not address the carbon contained in physical goods. Sustainability-marketed products grew 7.1 times faster than conventionally marketed products from 2015 to 2019. Further, eco-conscious customers now make up roughly 80% of a consumer market worth over $1.8 trillion. Many companies have already pledged to achieve carbon neutral or net zero carbon targets, with some aiming to achieve that target within the next decade.

Currently, we recycle carbon to produce ethanol that can be used for SAF production, the global addressable market for which is estimated at $180 billion. Our customers also operate our carbon refining technology in the single-cell protein market, estimated at $16 billion in 2019, because our process makes high protein biomass as a byproduct. Ethanol can also be converted to MEG and PET, with markets worth an estimated $28 billion for MEG and $44 billion for PET packaging at the end of 2021. We have a portfolio of existing recycled carbon and soon-to-be commercialized CarbonSmart products that we believe have the potential to penetrate more chemicals markets in the coming years as more commercial facilities begin operations. CarbonSmart is a concept where we see carbon waste transformed into many products that we use in our daily lives. Approximately two tons of CO2 are removed per ton of CarbonSmart product made.

Many of our customers and partners are brand owners who have made strong sustainability commitments and endeavor to connect their customers with low carbon products that do not compete with food production for feedstock, land, or water.

***Overview of Ethanol Market***

Ethanol can be used directly as fuel but can also serve as a feedstock to produce a broad range of products, including cosmetics and beauty products, hand hygiene products, paint, food additives, tires, children's toys, plastic products, rubber, clothing and upholstery. The United States is responsible for over half of ethanol production globally and has produced an average of nearly 15 billion gallons of ethanol annually since 2015, while the ethanol output for the rest of the world has increased by over 20% during the same period. Meanwhile, most governments have instituted caps on food-derived ethanol. The focus of most ethanol growth in the future is expected to be waste-based, non-food ethanol.

***Overview of Fuel Market***

In 2019, global fuel ethanol production reached 30 billion gallons. We believe the demand for renewable fuels and related infrastructure will rise substantially over the next decade driven by strong demand from both consumers and sustainability-focused suppliers. We also believe that the federal regulatory framework in the United States, including the Renewable Fuel standard, will drive production of ethanol for the liquid transportation fuel market. We believe the production of ethanol from recycled carbon, such as from industrial emissions, will also have a market in the European Union through the Renewable Energy Directive and at the state level in the United States with the California Low Carbon Fuel Standard. Other states in the Northeast United States, as well as Canada, have signaled they will institute such policies in the coming years.

*Sustainable Aviation Fuel*: Mandated global SAF demand is expected to hit 61 billion gallons per year by 2040. The Biden Administration has a goal of replacing all jet fuel with sustainable alternatives by 2050. The global market for aviation fuel is estimated to be nearly $250 billion by 2026. Airlines and aviation sector coalitions, including companies addressing Scope 3 emissions are making corporate commitments to increase SAF use. To reach expected 2030 SAF demand, global SAF capacity must achieve an 87% CAGR.

***Overview of Chemicals and Protein Markets***

According to the IEA, the chemicals sector is the largest industrial consumer of both oil and gas. Petrochemical feedstock accounts for 12% of global oil demand, a share that is expected to increase because of increasing demand for plastics, fertilizers, and other products. With the growth in demand for petrochemical products, petrochemicals are expected to account for over a third of the growth in oil demand to 2030, and nearly half to 2050, ahead of trucks, aviation, and shipping. Petrochemicals are also poised to consume an additional 56 billion cubic meters of natural gas by 2030. Currently, organic chemicals are predominantly derived from fossil sources such as petroleum. These chemicals are used to produce a wide array of materials. More than 10 million barrels of oil are consumed daily to create these materials, releasing massive quantities of new carbon into the atmosphere in the process.

Protein demand is outpacing supply. Today's alternatives are dominated by crop-based feedstocks. It is currently estimated that the plant-based protein market will be valued at $162 billion in 2030 and would make up an estimated 7.7% of the global protein market.

**Key Competitive Advantages**

We believe the following combination of capabilities and strengths distinguishes us from our potential competitors.

***Proven, Differentiated, Adaptable Proprietary Technology Platform*.** We are a leader in gas fermentation and have developed economically attractive, commercial-scale carbon recycling technology and end products. Our proprietary technology platform allows us to produce different products and chemicals from multiple feedstocks utilizing the same process at the same plant. Our biological system ensures stable performance despite fluctuating gas feedstock compositions, unlike thermocatalytic processes, which require consistent gas feedstock compositions.

New high-value chemical intermediates can be used to make materials such as acrylics, fibers, plastics and synthetic rubber and a wide variety of chemicals including alcohols, acids, esters, and ketones. LanzaTech has demonstrated this with several partners who have used chemical intermediates to make fabrics, packaging, detergent, cleaning agents and fragrances. This process can lock waste carbon into durable goods, creating a circular carbon economy where carbon is refined and re-used instead of emitted as harmful greenhouse gases.

We believe that our technology enables a circular carbon economy, which keeps carbon in the material cycle instead of allowing it to be emitted into the atmosphere as pollution. By locking carbon into chemical building blocks used to make every-day goods, we are reducing the need to extract virgin fossil resources to make the same products. We believe this could have a game changing impact on the chemical industry and its supply chain, shifting the way the industry considers commodity sourcing and supply.

***Low Carbon, Enabling Technology*.** Our technology is designed for use across the supply chain, from emitters of waste carbon to those who want to develop products from waste carbon. Industrial emitters can implement LanzaTech's carbon capture solution onto their existing facility and derive revenue from used carbon. As an example, the first commercial facility in China to utilize our technology platform has sold over 38 million gallons of ethanol into the market, displacing fossil gasoline for road transport use, and avoiding the equivalent of over 195,000 tons of CO2 emissions at source. Our technology platform allows emitters to play a role in the circular carbon economy by generating products from waste carbon that would otherwise come from virgin fossil resources and selling these products to end users who want to reduce their environmental impact.

***Our platform technology is highly customizable and we believe it will provide flexibility to respond to market demand*.** Through the use of synthetic biology, microorganisms can be engineered to produce different chemicals directly from gases using the same process and production hardware. By changing the microorganism in a commercial facility, we have developed the capability to switch the product focus of commercial plants within a matter of days. We believe this will enable production of different product targets in campaigns at the same commercial facility. We believe this capability will enable partners and customers to rapidly respond to fluctuating market conditions and maximize the value of their assets, by producing the highest value product at any given time.

***Platform Validated Through Partnerships with Industry Leaders*.** We have demonstrated the commercial success of gas fermentation on feedstocks from a broad array of waste streams. Three commercial scale facilities in China utilizing steel off-gas and ferroalloy off-gas emission are currently being operated by entities in which the Shougang Joint Venture holds a controlling interest. In addition, a commercial scale facility in Ghent, Belgium is in advanced stages of construction by our partner ArcelorMittal. The facility is expected to begin commissioning in the coming months.The pilot-scale plant in Japan developed with Sekisui has been producing ethanol from gasified municipal solid waste since 2017. Construction on a next scale 1/10th commercial sized facility with Sekisui was completed in April 2022 and the facility is in the commissioning stage. Additionally, a demonstration-scale facility in Alberta, Canada, with partner Suncor, utilizing waste-based feedstocks, including municipal waste and forestry-residues, has produced ethanol in test runs since July 2022 Commercial projects using refinery off-gases, industrial and biorefinery CO2, ferroalloy off-gases, gasified biomass, and gasified mixed plastic wastes are under development. We have worked with several partners on the integration of the gasification and gas fermentation processes to convert solid feedstocks to fermentation products, culminating in over 50,000 hours of pilot and demonstration scale operations on live synthesis gas ("syngas") produced from gasification.

As a result of our ability to deliver a sustainable, economically advantaged solution to produce fuels chemicals and products using waste feedstocks, we have been able to attract key industry partners in our markets such as Mitsui, ArcelorMittal, Suncor, BASF, IndianOil, and Sinopec.

In 2020, the Shougang Joint Venture plant that has been using our technology platform on a commercial scale received Roundtable on Sustainable Biomaterials ("RSB") certification. RSB certification is awarded to facilities that ensure the sustainability of their products and promote the health of their employee and the welfare of their local communities.

***Strong Intellectual Property Position*.** As of December 31, 2022, we owned or had licensed rights to 1,264 granted patents and 588 pending patent applications across 141 patent families in the United States, Europe, Asia and additional jurisdictions, in addition to our trade secrets. These issued patents and pending patent applications cover not only the upstream (such as gasification and gas conditioning), gas fermentation, and downstream (such as product separations and catalytic conversions) production systems that we are developing or may pursue in the future, but also certain of the underlying technologies used to develop our systems. Our intellectual property portfolio contains patent families spanning the entire platform, from the feedstock to the gas fermentation to the product recovery.

The following chart summarizes the breadth of our IP portfolio:

![amci-20230213_g3.jpg](amci-20230213_g3.jpg)

***Extensive Industry Experience***. We have over 17 years of experience developing, testing, scaling, and optimizing gas fermentation and integrating gas fermentation with upstream and downstream technologies, culminating in the world's first commercial gas fermentation plant in 2018. Our management team brings over 150 years of combined research and development, engineering and scale up, operations, partnering and licensing experience in the energy industry.

**Our Technology Platform**

***Overview***

We have developed, scaled, and deployed an adaptable proprietary technology platform that integrates core gas fermentation with upstream processes, such as gasification and gas conditioning, and downstream processes, such as product separations and catalytic conversions.

Our technology platform is like brewing, but instead of using yeast that eat sugar to make alcohol, our biocatalysts, or microbes, eat waste carbon to make end products. Because our system is biological, and biological systems grow in dynamic environments and react in real time to changing conditions, it is much more tolerant of variability in feedstock composition and supply than systems based on catalytic chemistry and is, therefore, highly customizable.

Our technology platform can use feedstocks containing CO2, H2 and CO, including waste emissions from steel, oil refining, and ferroalloy industries, gasified municipal solid waste ("MSW"), agricultural wastes, and reformed biogas. We have demonstrated this with partners globally and have shown conversion of these input streams at various scales, including at three commercial facilities in China being operated by entities in which the Shougang Joint Venture holds a controlling interest using industrial emissions. Our commercial partners will be able to

------

<u>[**Table of Contents**](#ib82e114cd19f45afae73e7a64e42f208_1390)</u>

combine our gas fermentation system with different engineered biocatalysts to produce different products, allowing them to leverage their existing capital investment and to calibrate production to market conditions.

![amci-20230213_g4.jpg](amci-20230213_g4.jpg)

**Step 1:** The process begins by receiving off-gas or waste gas streams comprising gases that contain various mixtures of CO, CO2 and H2, such as from steelmaking emissions or gasified waste.

**Step 2**: These gases are compressed, conditioned, and transferred into fermentation bioreactors containing LanzaTech's proprietary biocatalysts (microorganism) and a liquid media.

**Step 3:** The biocatalysts ferment the gases and, as part of their natural biology, they produce ethanol and other chemicals as a result of this fermentation. This is a continuous process that can run without shutting down for extended periods.

***LanzaTech's Biocatalyst***

*Clostridium autoethanogenum* is an Acetogen, a chemolithoautotrophic microorganism that uses certain gases for both carbon and energy. Acetogens naturally produce acetate, and a select subset of Acetogens, including *C*. *autoethanogenum*, natively synthesize ethanol. Acetogens are ubiquitous in anaerobic environments, such as soil, animal and human guts, sediments, the deep sea, and hot springs. For biotechnological applications, acetogenic clostridia are among the fastest growing acetogens and have been used industrially for more than 100 years.

Our technology platform relies on gas-consuming biocatalysts that use an ancient biological pathway known as the acetyl coenzyme-A biochemical pathway for autotrophic growth (the "Wood-Ljungdahl Pathway"). The Wood-Ljungdahl Pathway is the most energetically efficient carbon fixation pathway and enables our proprietary biocatalyst to transform the carbon and energy in gas streams into valuable products. In addition to being highly energy efficient, the Wood-Ljungdahl Pathway also allows high levels of dynamic flexibility in the composition of the gas streams (and therefore resources) that can be converted into valuable products. The pathway allows the LanzaTech process to use both CO2 and CO as sources of carbon and H2 and CO as sources of energy. The application of this pathway with this biocatalyst enables a significant range of sustainable, high volume, and globally available waste resources for commercial deployment and product manufacture.

***Feedstock Diversity for Resilience***

The current manufacture of essential goods results in an abundance of waste carbon in the form of polluting gases or solid wastes in the air, landfills, and waterways. The LanzaTech gas fermentation platform can utilize feedstocks ranging from CO to CO2-rich waste streams, including industrial and refinery off-gas, reformed biogas, gasified biomass and MSW, and CO2.

![amci-20230213_g5.jpg](amci-20230213_g5.jpg)

CO can provide both carbon and energy for our proprietary microbes. In contrast, CO2 only provides carbon, which means a source of chemical energy, H2, must be added for a CO2 conversion. In a CO-rich stream, the microbe can make the H2 it needs from water via a biological water gas shift reaction, creating CO waste streams of various compositions ideal for gas fermentation.

Waste carbon feedstocks generally have low cost, global availability with regional abundance, low carbon intensity, and are non-competitive with food production. If the entirety of the potential feedstocks could be accessed, up to 6.5 billion metric tons annually of gas fermentation products, primarily ethanol, could be produced**.**

Compared to other catalytic conversion processes, LanzaTech's gas fermentation process is uniquely tolerant to the inherent variability of waste gas composition, enabling a wide diversity of feedstocks and high variety of products. Upstream catalysis technology focuses on identification and removal of fermentation inhibitors before fermentation feedstock gases are introduced into the bioreactors. LanzaTech has developed and optimized its proprietary gas treatment system to remove more than four classes of fermentation inhibitors from the broad spectrum of feedstocks, gasified biomass to steel off-gasses, in a simple process that substantially decreases capital and operating expenses while providing increased flexibility.

*Potential Feedstocks*

The following feedstocks could be used with our platform technology:

Industrial Emissions

Steel, ferroalloy, or refinery off-gases are point-sourced. CO2-rich off-gases, which are produced by the cement and sugar ethanol industries, can also be used to feed gas fermentation alongside a hydrogen source as explained in subsequent sections.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Steel*: Energy-intensive manufacturing processes, such as steel production, inevitably result in gaseous emissions, which cannot be stored and which are emitted by the steel maker. As an environmental liability rich in CO, these emissions are an ideal feedstock for our process. We have been working with these readily available, abundant gases since 2008.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Ferroalloy*: Ferroalloy gases are also rich in CO, making this another ideal emission source. We are developing projects using ferroalloy gases in target regions such as China, Norway and India.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Refining*: Certain refinery off-gases are ideal feedstocks for our process. A unique feature of processing refinery gases is that most of the carbon in the ethanol produced is derived directly from CO2, rather than from CO. Oil and gas companies also have extensive experience producing and handling liquid fuels, gas processing, engineering, and chemical catalysis.

Solid Wastes and Reformed Landfill Gas

Biomass and agricultural residues offer the largest potential sources of feedstock for gasification. In contrast to other methods of converting biomass feedstocks into fuels, gasification and gas fermentation have the potential to utilize all carbon in the feedstock. This includes carbon contained in the natural polymer lignin, which is typically not accessible in current cellulosic biomass fermentation processes. Gasified non-recyclable MSW, mixed plastic waste, and reformed biogas such as landfill gas ("LFG") are abundant waste streams that we believe are currently underutilized sources of carbon for conversion into CarbonSmart fuels, chemicals, and materials using our technology platform.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Biomass: Biomass, such as agricultural and forestry residues, can be gasified into syngas. Syngas contains CO and H2 and is well suited for our process. While higher in capital costs due to the addition of one or more gasifiers, these projects typically benefit from significant renewable policy incentives, and can be deployed as smaller modular systems.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• MSW and Refuse Derived Fuel ("RDF"): As with biomass, MSW and RDF can also be gasified into syngas for use in our process, which can accept unsorted waste, ideally with mechanically recyclable items removed. The current alternatives are landfilling or incineration, which are increasingly falling out of favor globally, and so waste management companies are seeking alternative sustainable solutions. These projects benefit from tipping fees, or fees generated by the disposal and processing of waste on a per ton basis, on the waste, and in certain locations, can be deployed as smaller modular systems.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Reformed LFG: Only 32% of landfills in the United States collect methane, and the collection efficiency can range from 35% to 90% for modern landfills that do collect. As a result, landfills are responsible for more than 15% of the anthropogenic methane released in the U.S. Many landfills flare the LFG or operate older power generation units that emit large volumes of carcinogens and micro particles. LanzaTech believes it can utilize this gas stream. Capturing this feedstock for CarbonSmart materials has the potential to clean the air and improve human and environmental health surrounding landfills while reducing dependence on fresh fossil resources.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• As modern industries transition to more sustainable feedstocks, we believe industrial and refinery waste gases will ultimately transition as well. To enable this transition, LanzaTech is developing the ability to pivot to CO2 from biorefineries and direct air capture ("DAC") for continued, sustained, low carbon materials and fuels.

------

<u>[**Table of Contents**](#ib82e114cd19f45afae73e7a64e42f208_1390)</u>

*Future Proofing Feedstock Capability* 

CO2 sourced from biorefineries, industrial emissions, and DAC technologies can be coupled with H2 to produce products with extremely high carbon conversion efficiency of over 90% carbon utilization. Since H2 can be produced from renewable power via water electrolysis ("green") or by steam methane reforming with carbon capture ("blue"), the carbon footprint of the products made will be a fraction of that relative to petroleum refining. As more hydrogen is present in the feedstock, more carbon is captured into the ethanol product. We believe CO2 as a feedstock has the potential to disrupt the fuel and chemical supply chains by substituting CO2 for conventional fossil resources. By developing and integrating these approaches, we believe our technology platform is positioned to take advantage of the expected continued price reductions and capacity increases for renewable electricity, maximizing utilization of CO2 streams.

Integrating bioindustrial CO2 and eventually DAC technologies with LanzaTech's gas fermentation platform creates an opportunity for renewable fuel production from low-cost CO2 feedstock. Integrating with LanzaJet's Alcohol to Jet ("ATJ-SPK") process can produce SAF from each of ethanol derived from CO2 and H2 produced by water electrolysis. DAC CO2 to SAF is estimated to have a 94% emissions reduction when compared to the fossil counterpart at 94 g-CO2e/MJ of ATJ-SPK.

*Steel Industry Transition*

LanzaTech's gas fermentation technology can utilize the evolving off-gases from iron and steelmaking processes through the transition from carbon to hydrogen feedstocks. The LanzaTech system can remain in place, utilizing existing assets at iron and steel mills to take advantage of available hydrogen, coupled with carbon from other on-site sources including electric arc furnaces, or further transition to gasification of waste carbon resources (solid waste or biomass) or utilize direct air capture. We believe that our early investments in GHG emission reduction technology positions us to continue to be a leader in carbon recycling in other hard-to-abate sectors.

***Technology Platform Development***

Throughout our 17-year history, LanzaTech has consistently developed and scaled innovative gas fermentation technology solutions and is now deploying them commercially. Our team has designed and developed equipment necessary to enable the biocatalyst that functions in a 3-liter benchtop reactor to operate equivalently in a 750,000-liter fermentation reactor.

![amci-20230213_g6.jpg](amci-20230213_g6.jpg)

LanzaTech's gas fermentation process has been demonstrated at four sites with 50,000 hours of operation in the field using steel mill waste gases plus another 50,000 hours of operating in the field integrating gasification, gas treatment and gas fermentation. The success of these 100,000 hours of experience at pilot and demonstration scales

<u>[**Table of Contents**](#ib82e114cd19f45afae73e7a64e42f208_1390)</u>

led to the May 2018 startup of the first operating commercial gas fermentation facility in the world, at the Jingtang Steel Mill in Caofeidian in Hebei Province, China. A second commercial plant, the Shoulang Jiyuan plant in Ningxia, China, of the same capacity and utilizing ferroalloy off-gas come online in April 2021. The third commercial plant, the Ningxia Binze plant in Ningxia, China, with an annual capacity of 60,000 tons and utilizing ferroalloy off-gas, came online in September 2022. Together these facilities have produced over 50 million gallons of fuel-grade ethanol and mitigated over 250,000 tons of CO2. There are 14 additional plants being developed worldwide, 12 of which are commercial-scale and two are demo-scale or 1/10<sup>th</sup> commercial-scale. Four of the 12 commercial plants are in construction and the remaining eight plants are in engineering phases. The demo-scale facility and the 1/10<sup>th</sup> commercial-scale facility are in startup test run and commissioning phases, respectively. The 14 additional plants will use a mix of feedstocks including steel off-gas, ferroalloy off-gas, refinery off-gas, gasified biomass, gasified municipal solid waste, CO2 and green H2, and ethanol in instances where the plant will produce sustainable aviation fuel from the ATJ process.

LanzaTech is continuously developing and advancing its technology platform, and in late October 2022, announced that its next-generation bioreactor, currently utilized in a demonstration-scale facility in Alberta, Canada with partner Suncor, is expected to run additional test campaigns for ethanol production on a wide range of waste-based feedstocks. This next generation bioreactor is expected to improve the economic viability of LanzaTech's integrated biorefinery offering. The demonstration-scale facility has produced ethanol in test runs since July 2022 and converts waste-based feedstocks, including municipal waste and forestry-residues, into ethanol. Additional test campaigns are expected over the next several months along with full construction completion of the facility.

**Applications of Our Technology Platform**

***Overview***

Our technology platform enables companies around the world to generate revenue from transformed carbon in waste resources. Across the supply chain, we promote a CarbonSmart circular economy, where both resource providers and end users can choose to be carbon-efficient by recycling or "locking" carbon into new products rather than making them from new fossil resources. Current and proposed applications of our technology platform include ethanol products, which can serve as the chemical building blocks for consumer goods, such as household cleaners and sustainable fuels, including sustainable aviation fuel, as well as protein products, such as animal/fish feed and fertilizer. These applications are discussed further below.

To date we have partnered with several consumer-facing companies to demonstrate the market value of our CarbonSmart products. This includes leveraging our technology to make the chemical intermediates for the production of a new range of cleaning products, packaging for cosmetics, fibers for clothing, and as an input for fragrances. The ethanol used in these first CarbonSmart products originates in China at our commercial facilities, but we expect that over the longer term, the input ethanol will be made in our facilities across the globe.

***Ethanol Products***

Our customers and partners already have used our technology platform to produce ethanol, ethanol derivatives and ethanol co-products from steel mills, ferroalloy plants, and refineries, as well as gasified biomass and municipal waste.

To date, LanzaTech has produced over 1,000 metric tons of finished CarbonSmart products for consumer brands. Examples of CarbonSmart product launches are as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Purified ethanol in home cleaning products: LanzaTech's purified ethanol from steel mill off gas is utilized in a line of household cleaners.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Purified ethanol in fine fragrances: High purity ethanol is one of the major ingredients in fine fragrances. LanzaTech's high purity ethanol will be used in one of the world's largest fragrance and beauty company's fragrance formulations.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Ethanol as a feedstock for polyethylene production: LanzaTech ethanol was utilized for conversion to ethylene and then polyethylene, for use in manufacturing the world's first cosmetic bottle from steel mill emissions.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Ethanol as a feedstock for surfactant production: LanzaTech's partner launched a line of laundry detergents utilizing CarbonSmart ethanol as input for surfactants production.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Ethanol as a feedstock for polyester production: LanzaTech ethanol was utilized for conversion to ethylene and then monoethylene glycol (MEG) a building block for PET production. This was used to make yarns and fabric for lululemon and Zara apparel collections.

As of the date of this prospectus, 12 commercial-scale facilities are either under construction or in engineering utilizing our technology, as outlined in the graphic in the section titled "*Business — Market Opportunity — Overview*." The first commercial facility to use our technology was the Shougang Joint Venture in 2018, a joint venture between us and Shougang Group and TangMing formed in 2011. This gas fermentation plant was the world's first commercial facility to convert industrial emissions into sustainable ethanol. This plant has an annual production capacity of approximately 46,000 tons of ethanol.

*Sustainable Aviation Fuel Products*

Ethanol produced by us can be blended into road transport fuels or can be converted through the LanzaJet™ ATJ process to an ethanol-based ATJ-SPK and to sustainable diesel, both of which can be blended with their fossil equivalents. LanzaJet ATJ-SPK from our ethanol can demonstrate up to 80% GHG reduction compared to fossil alternatives depending on circumstances, including feedstock, geography and methodology. ATJ-SPK is qualified for use at up to a 50% blend level with conventional jet fuel for all commercial flights. This process is poised for commercial deployment. The process has a high potential jet yield of 90%.

Our first ATJ demonstration unit produced approximately 4,000 gallons of jet fuel and 600 gallons of diesel fuel. A portion of this fuel was used to power a commercial passenger 747-jet flight operated by Virgin Atlantic from Orlando, Florida to London, UK in 2018. The fuel was also used for a 2019 Trans-Pacific flight to deliver a new Boeing aircraft to All Nippon Airways in Tokyo from Everett, Washington.

We have designed our technology platform to convert ethanol to SAF, which is of strategic importance to airlines for meeting their commitments to reduce emissions.

LanzaJet

With the goal of accelerating commercialization of the ATJ process, we helped launch LanzaJet in June 2020 and became shareholders along with Suncor and Mitsui, with British Airways and Shell joining as shareholders in 2021. LanzaJet received financing from the Microsoft Climate Fund in 2022. We currently hold a 25% stake in LanzaJet. Mitsui, Suncor, British Airways and Shell have committed to invest a total of up to $165 million. This initial facility is currently under construction in Soperton, Georgia and will have the capacity to produce 10 million gallons per year of SAF and renewable diesel from sustainable ethanol sources. In December 2022, installation of key equipment for the novel process technology that converts ethanol to drop-in replacement SAF began and construction at the facility is expected to be completed in 2023. Pursuant to the LanzaJet License Agreement, we granted to LanzaJet a perpetual, worldwide, non-transferrable, irrevocable, royalty-free, sublicensable, exclusive license to certain patents related to the conversion of ethanol to fuel. This license is exclusive including as to us. The primary waste biomass to be used for ethanol feedstocks is cellulosic wastes from sugar cane or other agricultural activities in Brazil. Additional, longer-term waste-based biomass-derived feedstocks for SAF include waste starch slurry from conventional fermentation and biogas derived from biomass degradation in landfills. Waste-based industrial off-gases can also be used to produce ethanol as a feedstock for the process.

This plant, located at the LanzaTech Freedom Pines Biorefinery in Soperton, Georgia, is also supported by participation from All Nippon Airways and a US Department of Energy grant of $14 million.

We anticipate deployment of numerous commercial ATJ facilities above the 10 million gallons per year capacity of the LanzaTech Freedom Pines Biorefinery. We are currently working with partners to confirm project locations and solidify the appropriate project structures. Locations for these facilities include Asia, mainland Europe, the United Kingdom, and the United States. We expect these facilities will be funded by LanzaJet shareholders as well as other sources, including government grants and loan guarantees depending on the project structure and partners, location, and other factors.

DRAGON

In September 2021, Project DRAGON (Decarbonising and Reimagining Aviation for the Goal of Net Zero) was formally initiated. This waste-to-SAF project received GBP £3.15 million in grant funding from the UK Secretary of State for Transport (the "UK Authority") Green Fuels Green Skies program and £1 million from Innovate UK as part of the South Wales Industrial Cluster deployment program. LanzaTech is responsible for front-end engineering design and associated project development activities for the UK Authority to achieve a final investment decision for both the LanzaTech Gas Fermentation unit and the adjacent LanzaJet ATJ unit in Port Talbot, South Wales, United Kingdom. These activities, further supported in December 2022 by a £24.9 million grant from the UK Authority's Advanced Fuels Fund, are underway with a view to achieving a final investment decision in 2024 and full operations in 2026-2027 to produce 100 million liters per year of SAF for two major UK airlines. Overall the project is expected to play a significant role in meeting the UK government's target of 10% SAF by 2030, as well as resulting in significant carbon emissions reductions compared to fossil kerosene, and to also reduce emissions of particulate matter and sulfur.

FLITE

In December 2020, the Fuel via Low Carbon Integrated Technology from Ethanol, or FLITE, project was formally initiated. This project received EUR 20 million in grant funding from the EU Horizon 2020. LanzaTech is responsible for plant design, construction and operations using LanzaJet's ATJ technology. Project development has been initiated and we expect the FLITE facility to be fully operational in 2024 and to produce SAF using waste-based ethanol sourced from multiple European producers. In addition, the SAF expected to be produced at the facility is anticipated to result in a significant carbon emission reduction relative to fossil kerosene and to also reduce emissions of particulate matter and sulfur.

LanzaJet's ATJ technology is leveraging existing low-carbon intensity ethanol and is enabling a transition to new sources of waste-based ethanol.

Project LOTUS

In September 2021, SkyNRG Americas in partnership with LanzaTech was awarded $1 million in funding for Project LOTUS (**L**andfill **O**ff-gas **T**o **U**ltra-low carbon intensity **S**AF) to design, build, operate, and maintain a production facility that will convert raw LFG into SAF. The project is expected to leverage green hydrogen and LanzaTech's gas fermentation technology to convert LFG to ethanol at an operating landfill. The ethanol will be converted to SAF using the LanzaJet ATJ technology developed by LanzaTech and Pacific Northwest National Laboratory and subsequently licensed to LanzaJet. SkyNRG Americas has numerous contractual partners, including

------

<u>[**Table of Contents**](#ib82e114cd19f45afae73e7a64e42f208_1390)</u>

Boeing and Alaska Airlines, who are committed to advancing use of the fuel in flight once it is produced through project LOTUS.

![amci-20230213_g7.jpg](amci-20230213_g7.jpg)

We believe Project LOTUS has the potential to provide a new U.S.-produced regional supply chain for producing SAF that meets international ASTM specifications while reducing methane emissions and improving air quality. The SAF is expected to be high quality, low soot forming, and sustainably derived, with the potential to reduce up to 110% of GHG emissions over traditional jet fuels. The $1 million in funding from the Department of Energy, awarded in September 2021, is expected to accelerate the commercial rollout of this SAF production path from LFG by reducing the technical and financial risks for future integrated commercial plants across the United States.

***Protein Products***

An additional application of our technology platform is the production of protein products. Microbial protein is composed of lysed, spent microbes from LanzaTech commercial facilities. These microbes contain proteins and other valuable nutrients and have performed the task of gas fermentation, have been extracted from the relevant commercial unit and are no longer viable. These materials can be extracted and used in numerous applications, including feed products for livestock and fish, fertilizers for agricultural applications, and protein extract-based products. LanzaTech's first commercial customer is currently selling residual microbial protein as a component in fish and livestock feed products. Many of these markets are large and diverse, with stakeholders actively seeking sustainable and nutritious inputs. We believe our technology offers improved overall plant economics and environmental performance.

Significant composition testing on LanzaTech microbial protein has already been completed and detailed materials characterizations have been developed. These tests have shown that LanzaTech microbial protein products contain very high protein content, typically exceeding 85 weight percent of the overall material mass. In addition, LanzaTech's microbial protein product for fertilizer and feed applications contains high concentrations of B vitamins and other minerals. These materials are beneficial in certain end-use applications such as animal feeds.

We believe that animal feed is the most profitable application for microbial protein. Fertilizer and biogas applications currently provide alternatives where feed applications are impractical. The nearest term applications for LanzaTech microbial protein include:

*Animal/Fish Feed*

Using LanzaTech microbial protein as a key ingredient in fish and animal feed represents a significant opportunity for LanzaTech. Global fishmeal production alone is six to seven million tons annually. Separation and drying of microbial protein for feed applications is similar to that of fertilizers, leading to potentially higher margins for LanzaTech and its customers. Studies have demonstrated that LanzaTech microbial protein is effective as a

------

<u>[**Table of Contents**](#ib82e114cd19f45afae73e7a64e42f208_1390)</u>

partial replacement for fish meal and corn gluten meal in Atlantic Salmon at levels up to 15 weight percent in the diet. Nutrient digestibility and safety were demonstrated up to 30 weight percent in feed. Depending on region, regulatory approval may be required prior to marketing. Also, sufficient feed gas treatment is required for feed applications to ensure any detrimental gas contaminants do not enter the food chain.

*Fertilizer*

The global fertilizer market is roughly $150 billion and consists of approximately 187 million tons of materials sold annually. Fertilizer products draw widely different prices based on their compositions and availability. LanzaTech believes that its microbial protein has strong potential as a fertilizer that is easy to apply and low maintenance. Use as a fertilizer may require regional or local approval.

*Biogas*

In some markets, including the European Union, it is economically advantageous to anaerobically digest the residual microbial protein to produce biogas. This biogas can be used in a cogen unit to produce power, steam, and hot water for use in the industrial facility. In regions where there are strong government incentives promoting biogas production, this may be a profitable use of residual microbial protein.

***Synthetic Biology and Chemical Products***

Through our synthetic biology platform we can develop new microbes to produce additional chemical products.Our platform technology enables rapid scale-up of new microbes once they are developed. Beyond ethanol, we have demonstrated the ability to produce ethylene, isopropanol, and acetone directly from gases.

In 2022, LanzaTech demonstrated direct continuous production of ethylene from CO2, creating a new non- fossil fuel pathway to this widely used commodity chemical. With a projected global market value of $170 billion by 2030, ethylene is widely used in the chemical industry, and its worldwide production capacity (estimated over 200 million tons per annum in 2021) is one of the largest of any chemical. Using oil or natural gas as feedstock, petrochemical plants use the cracking process to extract ethylene, which is then transformed into chemical compounds and plastics, which manufacturers use to produce many of the products used every day, including:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Polyethylene (Plastics) – used to make food packaging, bottles, bags, and other plastics-based goods.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Ethylene Oxide / Ethylene Glycol – can become polyester for textiles, as well as antifreeze for airplane engines and wings.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Ethylene Dichloride – this, in turn, can become a vinyl product used in PVC pipes, siding, medical devices, and clothing.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Styrene – synthetic rubber found in tires, as well as foam insulation.

LanzaTech has previously produced ethylene via the indirect ethanol pathway, taking ethanol produced from carbon emissions and then converting this ethanol to ethylene. This latest development bypasses the conversion step, making the process less energy intensive and more efficient. With this, LanzaTech estimates that the ability to directly produce ethylene from a waste feedstock will offer a lower cost and lower carbon product, which is anticipated to enable greater market penetration than via the indirect ethanol pathway.

LanzaTech is scaling up the process to make these molecules. We have provided high-purity fermentation products (e.g. ethanol) and upgraded products (e.g., PET) to over 20 customers. Because this capability is unique to gas fermenting microbes, we have several collaborations with end users targeting the production of new molecules.

LanzaTech has achieved the direct synthesis of over 50 target products, molecules spanning from two-carbon up to 20+ carbon molecules and varying functional classes. LanzaTech has also demonstrated control over stereospecificity of the molecules, as well as the production of entirely novel compounds that cannot be produced in nature. In addition, LanzaTech has identified over 500 pathways for the production of an extensive spectrum of molecules using our proprietary predictive microbial modelling capability. Computer modelling simulations confirm

------

<u>[**Table of Contents**](#ib82e114cd19f45afae73e7a64e42f208_1390)</u>

the feasibility of producing these molecules from gas while providing accurate projections of achievable yields and therefore the economic case for each. Direct production of chemicals that today are produced via the ethanol conversion pathway, will make the process less energy intensive and more efficient. With this, LanzaTech estimates that the ability to directly produce chemicals from a waste feedstock will offer a lower cost and lower carbon product which will enable greater market penetration than via the indirect ethanol pathway.

We believe that our demonstrated ability to genetically modify our proprietary gas-fermenting microbe acetogen Clostridium autoethanogenum, is a competitive differentiator. While in recent years a number of rudimentary tools for gas fermenting organisms have been described in the public domain, these have low efficiency and are not amenable for use in high-throughput workflows. We have developed a complete suite of high-throughput capabilities essential for development of optimized production strains or application of iterative, machine learning-based screening strategies employed by the pharmaceutical or natural product industries. Specifically, we have assembled a fully automated strain fabrication facility capable of designing, engineering and delivering several thousand genetically re-programmed strains per month. This "*BioFab*" facility leverages the advanced computational biology, characterized libraries of genetic regulators, as well as tools and protocols to enable precise and predictable genetic re-programming of our proprietary gas-fermenting microbe. The combination of the capabilities and technologies that comprise the BioFab were developed in-house and are proprietary to us. Data from iterative cycles of design, construction, and analysis of engineered microbial strains within the BioFab is captured computationally and used to further refine our genetic modelling and strain design programs. Thus, over time these models and programs become increasingly accurate, minimizing the time required to deliver new commercial strains producing valuable chemical products.

We believe we can further expand our product portfolio through the industrial microbiology capabilities we have pioneered and use our technology to produce high-value chemical intermediates used to make materials such as acrylics, fibers, plastics, and synthetic rubber. In the future, once fully developed, we believe these new microbes will have the potential to be dropped into any existing industrial gas fermentation facility to make new products from established transformed carbon feedstocks, in many cases leading to carbon capture and sequestration in durable goods. We believe synthetic biology could enable the production of a wide variety of chemicals including alcohols, acids, esters, and ketones.

**Competition**

We compete in industries characterized by rapidly advancing technologies and a complex intellectual property landscape. We face competition from many different sources, including companies that enjoy competitive advantages over us, such as greater financial, research and development, manufacturing, personnel and marketing resources, greater brand recognition, and more experience and expertise.

While we do not believe we have any direct competitors, there are some companies with alignment in feedstock usage, products, synthetic biology, process design or commercial scale. While competing companies may be able to deliver some of these capabilities, we believe that no other company can currently deliver all of them in an integrated way.

These competitors may introduce competing products without our prior knowledge and without our ability to take preemptive measures in anticipation of their commercial launch. Competition may increase further as a result of greater availability of capital for investment and increased interest in our industry as more companies seek to facilitate the development of a carbon circular economy.

**Intellectual Property**

LanzaTech is a technology company which protects its intellectual property across an entire platform through a combination of trade secrets, confidential information, patents, trademarks, copyrights, nondisclosure agreements, material transfer agreements, employee agreements, and strong intellectual property and confidentiality clauses in collaboration and other agreements. We do not consider any individual patent, patent family or trademark to be material to our overall business.

***Patents***

As of December 31, 2022, we had owned or in-licensed 1,264 granted patents globally and 588 pending patent applications globally reflecting 141 patent families. We have filed patent applications continuously every year from 2007 to 2022, demonstrating continued innovation and establishing a steady patent estate viewed from a patent term perspective. As earlier filed patents reach their 20-year patent term, later filed patents remain enforceable thus providing a rolling patent estate of enforceable patents. Our patent estate is global in nature with patents or patent applications in over 50 individual countries and several pending applications in the International Patent System established by The Patent Cooperation Treaty.

***Trade Secrets and Confidential Information***

We have a large body of intellectual property that is maintained, not as patents, but as trade secrets and confidential information. Such intellectual property is protected by appropriate measures to maintain the secrecy and confidentiality of the intellectual property, including for example, contractual measures with confidentially and security obligations, physical security measures and digital security measures.

***Trademarks***

We maintain trademark rights and registrations in its name and brands in several global jurisdictions. Examples include "LanzaTech" and "CarbonSmart."

***Domains***

We have registered a number of domain names for website used in our business. For example, we have registered the domain name for "LanzaTech.com."

***Intellectual Property Overview and Risks***

Most of our intellectual property assets were developed and are owned solely by us, a few have been developed via collaboration, some of which are jointly owned with third parties, and a small number have been acquired or licensed from third parties. We expect that we will continue to make additional patent application filings and that we will continue to pursue opportunities to acquire and license additional intellectual property assets, technologies, platforms or products as developments arise or are identified.

Regardless, we cannot be certain that any of the patent filings or other intellectual property rights that we have pursued or obtained will provide the protection we seek. Our future commercial success depends, in part, on our ability to obtain and maintain patent and other proprietary protection for commercially important technology, inventions and know-how related to our business; defend and enforce our patents and other intellectual property; preserve the confidentiality of our trade secrets; and operate without infringing, misappropriating or violating the valid and enforceable patents and other intellectual property rights of third parties. Our ability to stop third parties from making, using, selling, offering to sell or importing our products may depend on the extent to which we have rights under valid and enforceable patents, trade secrets or other intellectual property rights that cover these activities. With respect to both our owned and licensed intellectual property, we cannot be sure that patents will issue with respect to any of the owned or licensed pending patent applications or with respect to any patent applications that we, our co-owners or our licensors may file in the future, nor can we be sure that any of our owned or licensed patents or any patents that may be issued in the future to us or our licensors will be commercially useful in protecting any products that we ultimately attempt to commercialize, or any method of making or using such products.

Under the "march-in" provisions of the Bayh-Dole Act, the government may have the right under limited circumstances to require us to grant exclusive, partially exclusive or non-exclusive rights to third parties under any intellectual property discovered through the government-funded programs. March-in rights can be triggered if the government determines that we have failed to work sufficiently towards achieving practical application of a technology or if action is necessary to alleviate health or safety needs, to meet requirements for public use specified by federal regulations or to give preference to U.S. industry. Specifically, certain of our granted and pending patents

------

<u>[**Table of Contents**](#ib82e114cd19f45afae73e7a64e42f208_1390)</u>

that cover recombinant and other microorganisms, cell-free protein synthesis platforms, protein expression vectors, fermentative production pathways, and microbial and ethanol conversion pathways may be subject to march-in-rights. These patents account for less than one percent of our granted and pending patents.

**Key Collaboration Agreements**

***License Agreement with Battelle Memorial Institute***

In September 2018, we entered into a license agreement with Battelle, which was subsequently amended in January and April 2020 (as amended, the "Battelle License Agreement"). Under the Battelle License Agreement, Battelle granted to us an exclusive sublicensable commercial license to certain patents related to the conversion of ethanol to fuels (the "Battelle patent rights").

Under the Battelle License Agreement, we must meet certain development milestones, including producing and selling products and sublicensing the Battelle patent rights to others within certain timeframes. The agreement also requires that any products manufactured using the Battelle patent rights and sold within the United States will be substantially manufactured in the United States. Battelle retains the right to practice or license the Battelle patents to nonprofit institutions for research, development, or demonstration purposes. We licensed our rights and obligations under the Battelle License Agreement exclusively to LanzaJet. As such, we may only exercise these rights through a sublicense from LanzaJet.

In connection with our entry into the Battelle License Agreement, we paid an initial fee of $5,000 and agreed to pay Battelle a royalty of less than one percent of net sales of products involving the Battelle patent rights and a 10% royalty on all sublicense revenues and royalties. As of the date of this prospectus, we have not been required to make any royalty payments under the Battelle License Agreement.

The Battelle License Agreement remains effective until the last of the Battelle patent rights expires, is abandoned or is adjudicated invalid, unless the agreement is earlier terminated. The last of the Battelle patent rights are currently scheduled to expire in approximately October 2035. Battelle may terminate the agreement if we become insolvent or if we fail to meet certain reporting or payment requirements under the agreement. Battelle may also terminate the agreement or convert the license into a non-exclusive license if we fail to reach certain of the abovementioned development milestones within the applicable time periods. We may terminate the Battelle License Agreement upon 60 days' prior notice to Battelle, and either party may terminate the agreement if the other party breaches the agreement and fails to cure such breach after 60 days' notice. We agreed to indemnify Battelle against certain third-party claims related to the Battelle patents.

***LanzaJet Agreements***

*LanzaJet Amended and Restated Investment Agreement*

On April 1, 2021, we entered into an amended and restated investment agreement with LanzaJet, Mitsui, Suncor, British Airways and Shell. We refer to this agreement as the "LanzaJet Investment Agreement." The LanzaJet Investment Agreement was entered into in order to facilitate the production of SAF by designing, constructing and operating a demonstration facility located at the LanzaTech Freedom Pines Biorefinery in Soperton, Georgia (the "LanzaJet Freedom Pines Demonstration Facility"), and to determine the feasibility of developing additional potential facilities for commercial scale production of fuel.

Under the LanzaJet Investment Agreement, we received shares of common stock of LanzaJet ("LanzaJet shares"), in exchange for a license to our rights and obligations under the Battelle License Agreement (discussed further below under "— License Agreement with LanzaJet"). Pursuant to the LanzaJet Investment Agreement, Mitsui, Shell, British Airways and Suncor each contributed an initial cash investment in exchange for shares of common stock of LanzaJet.

Each of Mitsui, Shell, British Airways and Suncor agreed to make an additional cash investment following the achievement of certain development milestones relating to the demonstration facility, which payments we refer to as second tranche investments. If made, the second tranche investments would fund the development and operation of

------

<u>[**Table of Contents**](#ib82e114cd19f45afae73e7a64e42f208_1390)</u>

commercial facilities by Mitsui, Shell, British Airways and Suncor, respectively. These commercial facilities would sublicense the relevant fuel production technology from LanzaJet. Upon the closing of each of the first three of these second tranche investments and no later than the sublicensing of the relevant facility, LanzaJet is required to issue additional LanzaJet shares to us. We currently hold approximately 25% of the outstanding shares of LanzaJet. Upon the issuance of additional shares to us in connection with the closing of each of the first three potential second tranche investments, we would hold approximately 40%, 50% and 57% of the outstanding shares of LanzaJet, respectively. Unless and until two second tranche investments are made and assuming none of the employee equity incentive pool is issued as shares, LanzaJet undertakes an initial public offering or a sale of LanzaJet occurs under certain circumstances, we would remain a minority shareholder of LanzaJet.

The LanzaJet Investment Agreement may be terminated by the mutual consent of the parties at any time or automatically as to the second tranche obligations of any party if LanzaJet has not called for such party to make a second tranche investment by December 31, 2025. Each party to the LanzaJet Investment Agreement agreed to indemnify the other parties for all claims arising from such party's breach of the agreement or from fraud, gross negligence, or willful misconduct with regard to the agreement.

*License Agreement with LanzaJet*

In May 2020, in connection with the LanzaJet Investment Agreement, we entered into the LanzaJet License Agreement. Under the LanzaJet License Agreement, we granted to LanzaJet a perpetual, worldwide, non-transferrable, irrevocable, royalty-free, sublicensable, exclusive license to all of our intellectual property rights under the Battelle License Agreement, as well as other intellectual property owned by us relating to the conversion of ethanol to fuels. LanzaJet assumed all of our obligations under the Battelle License Agreement, including development, reporting, royalty payment and sublicensing obligations. LanzaJet assumed all of our rights under the Battelle License Agreement except for our rights, in certain circumstances, to terminate the agreement, to amend the agreement or to assign our rights thereunder, provided that we may not exercise these rights without LanzaJet's prior consent.

The license granted by us to LanzaJet is exclusive, including as against us, with the exception of certain development projects we are undertaking in collaboration with the U.S. Department of Energy or pursuant to certain grants from the U.S. Department of Energy, for which LanzaJet granted us a worldwide, non- transferable, non-sublicensable, non-exclusive, royalty-free sublicense to the relevant intellectual property rights. LanzaJet also agreed to grant us a non-exclusive sublicense at most-favored nation pricing to fulfill certain pre-existing SAF obligations if we are unable to fulfill these obligations through other off-take agreements.

The LanzaJet License Agreement has an indefinite term. If LanzaJet fails to perform its obligations under the Battelle License Agreement, we may continue to perform our obligations under such agreement. LanzaJet may terminate the LanzaJet License Agreement immediately upon notice to us if a material portion of the licensed subject matter is determined by a court to be invalid. We may terminate the agreement upon 30 days' written notice if LanzaJet materially breaches the agreement and fails to cure after receiving notice of the breach. If certain commercial facility development milestones are not met under the LanzaJet Investment Agreement, we may terminate the LanzaJet License Agreement and after such termination, the agreement will survive solely with respect to the LanzaJet Freedom Pines Demonstration Facility. If the agreement is terminated for any other reason, LanzaJet's license will cease immediately but any sublicenses granted by LanzaJet prior to termination of the agreement will survive, subject to their terms. We and LanzaJet agreed to indemnify the other against certain third-party claims.

*LanzaJet Amended and Restated Stockholders' Agreement*

In connection with the LanzaJet Investment Agreement, on April 1, 2021, we entered into an amended and restated stockholders' agreement with LanzaJet, Shell, Mitsui, British Airways and Suncor (the "LanzaJet Stockholders' Agreement"). Under the LanzaJet Stockholders' Agreement, each party is required to hold and vote its shares of LanzaJet stock to ensure that LanzaJet's board of directors (the "LanzaJet board") is composed of eight directors: one designee from each of British Airways, Mitsui, Suncor and Shell, two LanzaTech designees (one of which will be the chairperson), LanzaJet's chief executive officer, and one independent director. Each party must

------

<u>[**Table of Contents**](#ib82e114cd19f45afae73e7a64e42f208_1390)</u>

hold a certain number of shares of LanzaJet common stock in order to maintain their respective designated board seats. Pursuant to the agreement, if a party votes to remove its designated director from the LanzaJet board, the other parties must also vote in favor of removal. If a party fails to comply with its obligations under the second tranche investments provided for in the LanzaJet Investment Agreement, the other parties may vote to remove that party's designee, and such party will forfeit its designated LanzaJet board seat in exchange for the right to designate a non-voting observer to the LanzaJet board.

The agreement also provides that the parties must vote their shares in favor of a proposed change of control transaction and take all reasonable steps necessary to execute the transaction if it meets certain standards and is approved by us, the LanzaJet board, and any investor holding a certain number of LanzaJet shares.

The parties to the LanzaJet Stockholders' Agreement may not transfer their LanzaJet shares until 2026, except for permitted transfers to affiliates. LanzaJet has a right of first refusal with regard to all transfers of LanzaJet shares to third parties and if LanzaJet declines to exercise this right, the other parties to the agreement are entitled to a pro rata right of first refusal. We and the other parties will also have a pro rata right of first refusal with regard to new LanzaJet shares issued as well as a put right with respect to LanzaJet shares that we and such parties hold upon the occurrence of certain conditions. The LanzaJet Stockholders' Agreement also provides registration rights in connection with an initial public offering of or other registration of LanzaJet shares.

Each party to the LanzaJet Stockholders' Agreement agrees to indemnify the other parties for all claims arising from such party's breach of the agreement or from fraud, gross negligence, or willful misconduct with regard to the agreement. The LanzaJet Stockholders' Agreement will terminate either with the consent of all of the parties or upon an initial public offering of LanzaJet shares or a specified liquidation event.

*LanzaJet Note Purchase Agreement*

On November 9, 2022, we and the other LanzaJet shareholders entered into the LanzaJet Note Purchase Agreement, pursuant to which FPF, a wholly owned subsidiary of LanzaJet, will issue, from time to time, notes in an aggregate principal amount of up to $147.0 million (the "LanzaJet Notes"), comprised of approximately $113.5 million aggregate principal amount of 6.00% Senior Secured Notes due December 31, 2043 and $33.5 million aggregate principal amount of 6.00% Subordinated Secured Notes due December 31, 2043. We have committed to purchase $5.5 million of Subordinated Secured Notes in a funding expected to occur on May 1, 2023. The Senior Secured Notes are secured by a security interest over substantially all assets of FPF, and both the Senior Secured Notes and the Subordinated Secured Notes are secured by a security interest over all intellectual property owned or in-licensed by LanzaJet. LanzaJet also provides a guarantee of any costs and expenses required to complete the LanzaJet Freedom Pines Demonstration Facility and achieve commercial operation.

Each purchaser of LanzaJet Notes under the LanzaJet Note Purchase Agreement is also entitled to receive a warrant for the right to purchase 575 shares of common stock of LanzaJet for each $10,000 of LanzaJet Notes purchased by such purchaser (which, in the case of LanzaTech, will be equal to a right to purchase 316,250 shares of common stock of LanzaJet).

Under the LanzaJet Note Purchase Agreement, FPF must provide periodic progress reports and financial information to the noteholders, in addition to providing notice of certain significant events. Additionally, FPF is restricted from undertaking certain transactions or making certain restricted payments while the LanzaJet Notes are outstanding. The LanzaJet Note Purchase Agreement may be amended with the approval of FPF and all noteholders. Upon an event of default under the Note Purchase Agreement, each purchaser may accelerate its own LanzaJet Notes. Enforcement against the collateral securing the LanzaJet Notes requires the approval of certain holders as specified in the LanzaJet Notes. Under the LanzaJet Note Purchase Agreement, FPF has agreed to indemnify the noteholders for certain liabilities.

***Mitsui Alliance Agreement***

On February 15, 2022, we entered into an amended and restated collaboration agreement with Mitsui which was further amended on March 24, 2022 and October 2, 2022 (as amended, the "Mitsui Alliance Agreement"). Under the Mitsui Alliance Agreement, Mitsui must use commercially reasonable efforts to promote our gasification, waste-to-

------

<u>[**Table of Contents**](#ib82e114cd19f45afae73e7a64e42f208_1390)</u>

ethanol and CarbonSmart technology and establish commercial facilities using this technology in Japan. In exchange, we agreed to exclusively promote and designate Mitsui as our preferred provider of investment and off-take services worldwide, as well as our preferred provider of engineering, procurement and construction services in Japan, subject to exceptions for certain of our existing commercial partnerships that allow us to recommend Brookfield as a provider of investment services in specified circumstances, including the Brookfield Framework Agreement. We and Mitsui agreed to share prospective customer information and to structure package offerings of our combined services through either a joint venture or royalty payment structure.

Under the Mitsui Alliance Agreement, we may not recommend any alternative provider of the aforementioned services without the advance written consent of Mitsui. In addition, we agreed to provide Mitsui with the right to first offer its services to any customer who requires or requests these services. We must obtain written consent from Mitsui before soliciting customers or marketing or recommending our waste-to-ethanol technology in Japan.

The Mitsui Alliance Agreement may be terminated by Mitsui without cause with three months' notice. The agreement may be terminated by us or Mitsui if the other party becomes insolvent or if the agreement is materially breached and the breaching party fails to cure within 30 days after receiving notice of the breach. We and Mitsui have agreed to indemnify each other against certain third-party claims.

***Shougang Joint Venture***

*Articles of Association of Beijing Shougang LanzaTech Technology Co., Ltd*

Through our subsidiary LanzaTech Hong Kong Limited, a limited liability company organized in Hong Kong, we hold approximately 9.3% of the outstanding shares of Beijing Shougang LanzaTech Technology Co., Ltd (the "Shougang Joint Venture") as a result of our contribution of certain intellectual property rights (see " — *Shougang Joint Venture License Agreement*" below). Our rights and responsibilities as a holder of such shares are set forth in the Shougang Joint Venture's Articles of Association,effective in November 2021. Because our shares were issued before an initial public offering of the Shougang Joint Venture, our shares may not be transferred within one year from the date on which the Shougang Joint Venture's shares are publicly listed. The Shougang Joint Venture has an indefinite duration.

At the general meeting of shareholders of the Shougang Joint Venture, shareholders have the authority to determine the Shougang Joint Venture's business plan, elect and replace directors, increase or decrease the registered capital of the Shougang Joint Venture, amend the Shougang Joint Venture, dissolve the Shougang Joint Venture, and approve certain transactions, among other functions. As a holder of more than 3% of the shares of the Shougang Joint Venture, we have the right to submit proposals to the Shougang Joint Venture at general meetings.

Except as otherwise provided, and in accordance with accounting provisions of the Shougang Joint Venture, when a distribution of Shougang Joint Venture profits is approved, the Shougang Joint Venture's after-tax profits are distributed in proportion to the shares held by shareholders. In the event of a liquidation, the Shougang Joint Venture's property must be distributed in proportion to the shares held by shareholders after liquidation expenses, wages of employees, statutory compensation, owed tax and Shougang Joint Venture debts are paid. If we object to a resolution on merger and division of the Shougang Joint Venture, we can request the Shougang Joint Venture acquire our shares.

*Shougang Joint Venture Letter Agreement*

On November 3, 2021, LanzaTech Hong Kong Limited entered into a side letter of agreement (the "Shougang Joint Venture Letter Agreement") with the Shougang Joint Venture and Mitsui. The Shougang Joint Venture Letter Agreement sets forth the parties' mutual understanding that if the Shougang Joint Venture decides not to pursue an initial public offering of its securities in China or if an initial public offering does not take place by the end of 2024, the Shougang Joint Venture will make commercially reasonable efforts and discuss in good faith with shareholders the possibility of restoring certain provisions from a previous version of the Shougang Joint Venture Articles, including provisions granting shareholders rights to financial records, board composition provisions, and provisions requiring unanimous consent of the board to make certain decisions.

*Shougang Joint Venture License Agreement*

On September 6, 2021, we entered into an Intellectual Property Rights License Agreement with the Shougang Joint Venture, which was subsequently amended in January 2022 (as amended, the "Shougang Joint Venture License Agreement"). Under the Shougang Joint Venture License Agreement, we granted the Shougang Joint Venture a license to certain of our intellectual property rights, including certain patented fermentation processes, alcohol production processes, novel bacteria and trademarks. The license we granted to the Shougang Joint Venture is a non-transferable (except with our written consent), exclusive, sublicensable commercial license under the licensed subject matter, to utilize gas fermentation technology to produce ethanol and by-products at commercial facilities in China. The Shougang Joint Venture may sublicense its rights to third-party contractors acting on its behalf, subject to certain conditions.

In consideration for the licenses we granted to the Shougang Joint Venture, the Shougang Joint Venture agreed to pay us a royalty on a graduated scale from 10% to 20% of all sublicensing revenues received by the Shougang Joint Venture in connection with the establishment and sublicensing of certain commercial facilities by the Shougang Joint Venture after the first commercial facility. As of the date of this prospectus, we have not received any royalty payments from the Shougang Joint Venture. Because our shareholding ratio in the Shougang Joint Venture has fallen below 10% due to a financing prior to the submission of an application by the Shougang Joint Venture for an initial public offering on a securities exchange in China, we have the right to request an adjustment to the royalty rates payable to us by the Shougang Joint Venture. This right will automatically terminate upon the submission of an application by the Shougang Joint Venture for an initial public offering on a securities exchange in China. If such application is subsequently terminated, our right to request an adjustment to the royalty rates will resume. The Shougang Joint Venture License Agreement provides that we will solely own all developed technology that results from, is based on, or uses the licensed subject matter in the operation of the Shougang Joint Venture, and all such technology will be subject to the license granted to the Shougang Joint Venture.

The Shougang Joint Venture has a right to cooperate with third parties regarding any commercial license under the licensed subject matter, subject to certain conditions. We agreed not to enter into any agreement with any third party preventing the Shougang Joint Venture's rights on the licensed subject matter in China. If the Shougang Joint Venture has not entered negotiations or signed an agreement with a third party for commencement of a project within a certain period of time, we will be free to engage with such third party ourselves.

Upon submission of an application by the Shougang Joint Venture for an initial public offering on a securities exchange in China, if we enter liquidation and as a result the Shougang Joint Venture License Agreement is terminated, the Shougang Joint Venture will be granted an option to call for an assignment of patents that are licensed pursuant to the agreement at that time, provided we first receive a written irrevocable, non-exclusive sublicense for the surviving term of such patents. If the Shougang Joint Venture's application for an initial public offering is revoked or otherwise terminated, this call option will automatically become void. If the Shougang Joint Venture's right to the licensed subject matter is prohibited or restricted by operation of United States export controls, the Shougang Joint Venture has the right to continue to use the licensed subject matter as provided in the agreement. In such event, so long as the Shougang Joint Venture's continued use of the licensed subject matter complies with the agreement, we agreed not to initiate patent infringement claims against the Shougang Joint Venture.

The Shougang Joint Venture License Agreement will continue until the earlier of (a) the date the final licensed intellectual property right expires or terminates, (b) the date the last commercial facility is permanently decommissioned and (c) termination of the agreement. The agreement will terminate automatically in the event that the Shougang Joint Venture dissolves or is liquidated, institutes or actively participates in any action, suit or proceeding to invalidate or limit the scope of the licensed subject matter, or breaches certain provisions of the agreement. We may terminate the Shougang Joint Venture License Agreement upon default by the Shougang Joint Venture if the Shougang Joint Venture does not remedy the default within 60 days. We agreed to indemnify the Shougang Joint Venture, its affiliates and their current and former representatives from claims resulting from our material breach of the representations and warranties of the Shougang Joint Venture License Agreement. We have the first right to enforce and defend against infringement of the intellectual property licensed under the Shougang Joint Venture License Agreement and to recover any monetary compensation awarded in any litigation proceedings.

------

<u>[**Table of Contents**](#ib82e114cd19f45afae73e7a64e42f208_1390)</u>

If we fail to do so, the Shougang Joint Venture may enforce and defend the licensed intellectual property against infringement.

*Letter Agreement with Sinopec*

On April 12, 2021, we entered into a letter agreement with Sinopec and the Shougang Joint Venture (the "Sinopec Letter Agreement"). The parties to the Sinopec Letter Agreement agreed that the Shougang Joint Venture has exclusive rights to use our gas fermentation technology in commercial projects in China to produce fuel ethanol using steel mill and ferroalloy off-gas as described in the Shougang Joint Venture License Agreement. The Shougang Joint Venture agreed to notify Sinopec and us if it enters into a term sheet or equivalent preliminary agreement with respect to the use of our gas fermentation technology in commercial projects in China falling outside the scope of the Shougang Joint Venture License Agreement.

Sinopec and the Shougang Joint Venture have the right to cooperate with us on commercial projects outside the scope of the Shougang Joint Venture License Agreement and to provide technical and engineering services.

***Grant Agreement with the European Climate, Infrastructure and Environment Executive Agency***

Through our subsidiary LanzaTech BV, on October 7, 2020, we entered into a Grant Agreement (the "CINEA Grant Agreement") with the European Climate, Infrastructure and Environment Executive Agency (formerly the Innovation and Networks Executive Agency of the European Union) ("CINEA"), along with SkyNRG BV ("SkyNRG"), RSB Roundtable on Sustainable Biomaterials Assocation, E4tech (UK) Ltd and Fraunhofer Gesellschaft zur Forderung der Angewandten Forschung E.V. The CINEA Grant Agreement provides for the award of a grant from CINEA to the parties to the CINEA Grant Agreement to fund the "Fuel via Low Carbon Integrated Technology from Ethanol" program, which we refer to as the FLITE program, to expand the supply of low carbon jet fuel in Europe by designing, building, and demonstrating an innovative ethanol-based ATJ technology in an ATJ Advanced Production Unit. Pursuant to the CINEA Grant Agreement, LanzaTech is responsible for plant design, construction and operations using ATJ technology. The CINEA Grant Agreement contemplates that FLITE will occur for a period of 48 months ending on November 30, 2024.

The maximum grant amount under the CINEA Grant Agreement is EUR 20,000,000. The grant is applied to 100% of non-profit eligible costs and 70% of for-profit eligible costs. The estimated eligible costs of implementing the FLITE program are approximately EUR 54,500,000.

Pursuant to the CINEA Grant Agreement, we own any intellectual property generated as a result of our participation in the program. If we do not protect, exploit and disseminate such intellectual property rights, to the extent reasonable and possible, CINEA may assume ownership thereof.

The parties must compensate CINEA for any damage it sustains as a result of the parties' implementation of the FLITE program or because the FLITE program was not implemented in full compliance with the CINEA Grant Agreement.

The participation of a party may be terminated by the coordinator of the CINEA Grant Agreement, designated as SkyNRG, upon request of the concerned party or on behalf of the other parties, subject to certain notice requirements and based upon reasons that must be approved by CINEA. CINEA may independently terminate the CINEA Grant Agreement or the participation of one or more parties in certain enumerated situations, including a party's change in financial or organization situation likely to affect the program, substantial errors or serious breach of obligations under the agreement, systemic errors or fraud in other similar agreements, and force majeure.

The agreement may be amended by request of any of the parties subject to the procedural guidelines therein. The agreement may be terminated by the parties with cause, or without cause subject to a potential reduction of the grant amount.

**Agreements with Sekisui Chemical Co., Ltd.**

***Memorandum of Understanding with Sekisui***

On June 20, 2018 we entered into a Memorandum of Understanding with Sekisui with respect to the business of producing ethanol converted by microbes from syngas generated from municipal solid waste, industrial solid waste, and other waste materials (the "Sekisui MOU").

Under the Sekisui MOU, we and Sekisui agreed to notify each other of any new projects or opportunities anywhere in the world relating to waste-to-ethanol production, to the extent legally permissible, and to inform relevant third parties of the other party's intent to participate in such new projects. If Sekisui notifies us of a business project in Japan, we agreed not to grant or license our technology or provide media, microbes, or technical support to the project without Sekisui's consent. Sekisui will manage developing and establishing appropriate structures related to the waste to ethanol production, collection of license fees, providing main and non-specialized technical support of operations, and media and microbe distribution following our manufacture thereof.

The Sekisui MOU expires on June 20, 2028, at which point we and Sekisui must engage in good faith discussions on whether to extend the term. We also must engage in good faith discussions to determine whether the Sekisui MOU should be terminated or amended if there is a substantial change for either party relating to the performance of or responsibility for waste to ethanol production, including changes in control or ownership of either party.

***Sekisui Term Sheet***

On February 21, 2020, we entered into a term sheet with Sekisui (the "Sekisui Term Sheet") in connection with the development of a waste-to-ethanol commercial facility. The Sekisui Term Sheet addresses the provision of engineering services by LanzaTech to the future operator of the commercial facility, and the granting of a license by LanzaTech to Sekisui for certain information, technology and intellectual property necessary to design, operate, and maintain the fermentation processes, microbes, and ethanol by-products of the commercial facility. The Sekisui Term Sheet governs the terms of operation of the first commercial facility and any future facilities contemplated under the Sekisui Memorandum, including with respect to performance targets and guarantees and engineering fees.

Under the Sekisui Term Sheet, we are expected to provide, sell or distribute microbes and trace media for the operation of the commercial facility for a fixed fee, subject to mutually agreed price adjustments for future facilities. For any additional facility that is constructed in accordance with the terms of the Sekisui Memorandum, we would not provide trace media or microbes without Sekisui's consent.

After a certain date, the fixed fee arrangement is expected to end and we expect to charge our standard price for the microbes and trace media. At that point, Sekisui may choose which type of microbes and trace media it would like to purchase from us, and we must carry stock of the same microbes sold to Sekisui for at least one year from the last delivery.

The entity operating the commercial facility is required to pay to us and Sekisui a license fee consisting of a percentage of gross sales of all products which utilize our licensed subject matter. Our portion of the licensing fee is a single-digit percentage of gross sales of all products which utilize our licensed subject matter. As of the date of this prospectus, we have not received any payments under the Sekisui Term Sheet. The provisions of the Sekisui Term Sheet relating to the license and supply of media and microbes continue in effect as long as the commercial facility is operating. Once in effect, we may terminate the license for uncured material breach, if the licensee becomes insolvent, or if there is a change of control or assignment without our consent.

**Grant Agreement between LanzaTech UK Limited and UK Secretary of State for Transport**

On December 12, 2022, LanzaTech UK Limited ("LanzaTech UK"), a wholly owned subsidiary of LanzaTech, was awarded a grant from the UK Authority in connection with Project DRAGON. The grant was awarded to fund LanzaTech UK's front-end engineering design and associated project development activities for the UK Authority to achieve a final investment decision for a proposed facility in Port Talbot, South Wales, United Kingdom. The

------

<u>[**Table of Contents**](#ib82e114cd19f45afae73e7a64e42f208_1390)</u>

proposed facility would use LanzaTech's process technology to convert a variety of waste sources into waste-based low-carbon ethanol. This ethanol would then be converted to SAF and diesel fuel using LanzaJet's ATJ technology.

Pursuant to the grant agreement between LanzaTech UK and the UK Authority (the "DRAGON Grant Agreement"), the UK Authority agreed to provide to LanzaTech UK up to £24,961,000 upon the achievement of certain milestones related to Project DRAGON. In return, LanzaTech UK agreed to provide regular progress reports, audit reports, and documentation of its expenses to the UK Authority. In the event that LanzaTech UK defaults on its obligations under the DRAGON Grant Agreement, the UK Authority may suspend payments under the agreement, reduce the amount of the grant, require LanzaTech UK to repay amounts paid under the grant with interest, or terminate the agreement. All intellectual property rights owned by each of the parties prior to the date of the DRAGON Grant Agreement or developed by either party during the period of the grant will remain the property of such party. However, any intellectual property rights developed in the course of the activities funded by the grant and included in LanzaTech's periodic progress reports to the UK Authority will belong to the UK Authority.

Either party may terminate the DRAGON Grant Agreement for convenience upon 28 days' written notice. Upon termination of the DRAGON Grant Agreement, LanzaTech UK must return any unspent funds issued under the grant and promptly prepare a plan to terminate funded activities. If the UK Authority terminates the agreement for convenience, it will be obligated to pay to LanzaTech UK a reasonable amount in respect of any activities completed in furtherance of Project DRAGON at the time of termination, but will not be liable for any expenses related to any transfer or termination of any of LanzaTech UK's employees engaged in activities related to Project DRAGON. The period for which the grant is awarded expires on March 31, 2025.

LanzaTech UK has agreed to indemnify and hold harmless the UK Authority and its representatives with respect to all actions, claims, charges, demands, losses and/or proceedings arising from or incurred by reason of the actions or omissions of LanzaTech UK in connection with Project DRAGON. To the extent permitted under applicable law, the UK Authority's liability to LanzaTech UK under the DRAGON Grant Agreement will be limited to its obligation to make payment of grant funds when due and payable.

**Agreements with Brookfield**

***Brookfield Framework Agreement***

On October 2, 2022 we entered into a framework agreement with BGTF LT Aggregator LP, an affiliate of Brookfield Asset Management Inc. ("*Brookfield*" and such agreement, the "Brookfield Framework Agreement"). Under the Brookfield Framework Agreement, we agreed to exclusively offer Brookfield the opportunity to acquire or invest in certain projects to construct commercial production facilities employing CCT technology in the U.S., the European Union, the United Kingdom, Canada or Mexico for which we are solely or jointly responsible for obtaining or providing equity financing, subject to certain exceptions. We agreed to present Brookfield with projects that over the term of the agreement require equity funding of at least $500,000,000 in the aggregate. With respect to projects acquired by Brookfield, we are entitled to a percentage of free cash flow generated by such projects determined in accordance with a hurdle-based return waterfall. Brookfield has no obligation under the Brookfield Framework Agreement to invest in any of the projects. Additionally, we agreed to recommend Brookfield to customers that, in our reasonable judgment, are likely to need third-party funding to develop, construct and own projects subject to the Brookfield Framework Agreement.

Brookfield's exclusivity will terminate upon the earliest of (a) the aggregate equity funding by Brookfield in projects acquired by Brookfield of at least $500,000,000, along with Brookfield's written notice that it will no longer maintain access to at least $500,000,000 to fund new projects, (b) Brookfield's rejection of a specified number of projects that otherwise meet certain criteria over a specified time period, and (c) October 2, 2027, which is the date the Brookfield Framework Agreement is set to terminate.

***Brookfield SAFE***

On October 2, 2022, concurrently with entry into the Brookfield Framework Agreement, we entered into a Simple Agreement for Future Equity with Brookfield (the "Brookfield SAFE"). Under the Brookfield SAFE, we agreed to issue to Brookfield the right to certain shares of Legacy LanzaTech's capital stock, in exchange for the

------

<u>[**Table of Contents**](#ib82e114cd19f45afae73e7a64e42f208_1390)</u>

payment of $50,000,000 (the "Initial Purchase Amount"). Following the completion of the Business Combination, Brookfield may, at any time at its option, convert all or a portion of the Initial Purchase Amount less any amount that has already been converted or repaid (the "Purchase Amount") into shares of the common stock. The number of shares into which the Purchase Amount and the Non-Repayable Amount (as defined below) are convertible is determined by dividing such amount by the price per share paid by the PIPE Investors ($10.00).

On the fifth anniversary of the Brookfield SAFE, we will repay in cash any remaining unconverted portion of the Initial Purchase Amount (the "Remaining Amount"), plus interest in the high single digits, compounded annually. For each $50,000,000 of aggregate equity funding required for qualifying projects acquired by Brookfield in accordance with the Brookfield Framework Agreement, the Remaining Amount would be reduced by $5,000,000 (such reduction, the "Non-Repayable Amount"). Equity funding for any one or more projects in excess of $50,000,000 in the aggregate will be counted towards the next $50,000,000 of equity funding required for qualifying projects.

We may be required to repay the Brookfield SAFE prior to the fifth anniversary if upon a conversion event, if we take certain actions that would cause us to be unable to satisfy our obligations under the Brookfield SAFE, including failure to provide for certain rights to Brookfield in an Equity Financing or taking any action that would reasonably be expected to cause the fair market value of LanzaTech to fall below $200,000,000. LanzaTech, Inc. provided a guarantee for LanzaTech to repay its obligations under the Brookfield SAFE, including any expenses incurred by Brookfield in enforcing or exercising its rights under such guarantee.

In the case of a liquidation or dissolution of LanzaTech, Brookfield would be entitled to receive a portion of the proceeds equal to the Purchase Amount plus interest in the high single digits, compounded annually, and such right would be on par with unsecured indebtedness of LanzaTech, and rank senior to any outstanding common stock, preferred stock and other SAFEs.

The Brookfield SAFE will automatically terminate following the earliest occurrence of (A) the Initial Purchase Amount having been fully repaid and/or converted and (B) the payment of amounts due to Brookfield in the event of a liquidation or dissolution of LanzaTech.

***Brookfield Cooperation Letter Agreement***

On October 2, 2022, in connection with our entry into the Brookfield Framework Agreement, we entered into a letter agreement with Suncor and Brookfield (the *"*Brookfield Cooperation Letter Agreement"). Under the Brookfield Cooperation Letter Agreement, we agreed to simultaneously notify Suncor upon the submission of any notice to Brookfield that a project is construction-ready under the Brookfield Framework Agreement for any equity investment opportunity in Canada or Colorado. For any of such investment opportunities Brookfield pursues, Brookfield has agreed under the Brookfield Cooperation Letter Agreement to grant Suncor the right to invest up to a certain percentage that lies between 15 – 25% of the required equity capital on economic terms at least as favorable as those granted to Brookfield and any other third-party investors.

Under the Brookfield Cooperation Letter Agreement, Suncor agreed to notify Brookfield of any projects using our technology that Suncor establishes which require equity capital from a third-party. Suncor has also agreed to consider any investment proposal presented to it by Brookfield pursuant to such notification prior to the execution of agreements with other third parties.

***Letter Agreement with IndianOil***

On December 4, 2017, we entered into a letter of agreement (the "IndianOil Letter Agreement") with IndianOil. The IndianOil Letter Agreement sets forth a framework for the development of a plant utilizing our technology to produce ethanol from waste gas at IndianOil's Panipat refinery in Haryana, India, as well as terms for future agreements for the development of additional plants by IndianOil or other third parties. In connection with the IndianOil Letter Agreement, we licensed to IndianOil certain technology used to produce ethanol from waste gas in exchange for royalties in the range of $13 to $14 per metric ton of ethanol, net of any applicable tax, by the first plant. For each additional plant developed by IndianOil, IndianOil has agreed to a royalty between $28 and $31 per metric ton of ethanol for a period of five years or alternatively, a lump sum license fee of $8 million for an ethanol

------

<u>[**Table of Contents**](#ib82e114cd19f45afae73e7a64e42f208_1390)</u>

unit with a capacity of 40,000 metric tons per year, or on a proportionate basis predicated on the actual size of the future unit. As of the date of this prospectus, we have not received any royalty or lump sum license fees under the IndianOil Letter Agreement. IndianOil agreed to purchase design and engineering services, proprietary microbes and trace media mix from us to facilitate the construction and operation of the first IndianOil plant. Additionally, we agreed to provide IndianOil with terms for commercial deployment of our waste gas to ethanol process that are at least as favorable as those that we may grant to third parties (other than parties in which we have ownership or co-development projects we may undertake with third parties) in addition to an exclusivity period during which we have agreed to engage IndianOil as our engineering partner for commercial plants developed by third parties using the oil refinery technology we licensed to IndianOil. The IndianOil Letter Agreement terminates on December 4, 2027, unless earlier terminated by mutual agreement.

***Suncor License Agreement***

On October 6, 2020, we entered into a Master Licensing Agreement with Suncor, which was amended and supplemented on October 2, 2022 by the Brookfield Cooperation Letter Agreement (as amended, the "Suncor License Agreement"). Pursuant to the Suncor License Agreement we granted Suncor a worldwide, non-exclusive, license to certain of our intellectual property related to our gas fermentation technology, which is sub-licensable only to joint ventures affiliated with Suncor and transferable only with our consent.

This license is conditional on Suncor's fulfillment of certain obligations including the provision of financing, engineering, and other project support services reasonably required for us to accomplish certain developmental and funding targets. Suncor paid us an initial license fee of $5 million Canadian and has agreed to pay us a royalty of up to 10% of net revenue from excess ethanol produced at the first four commercial facilities developed under our joint development plans with Suncor above a certain daily quota and on all ethanol produced at additional facilities developed under our joint development plans with Suncor. Alternatively, Suncor may pay a one-time royalty fee for any licensed facility, which would be calculated based on the potential capacity of such facility. As of the date of this prospectus, we have not received any royalty payments under the Suncor License Agreement.

Pursuant to the Suncor License Agreement, we granted most favored customer pricing to Suncor with regard to our engineering services, supply of equipment and microbes, and royalties from commercial facilities. Additionally, we granted Suncor a right of first refusal with regard to any investment in or off-take from any future commercial gas fermentation plants in Canada and Colorado, other than investment opportunities offered to Brookfield or its affiliates under the Brookfield Framework Agreement which would be subject to the provisions of the Brookfield Framework Agreement described above.

The Suncor License Agreement may be terminated by agreement of both parties if either party becomes insolvent, commits a material breach and fails to remedy such breach within a certain timeframe or if no commercial facilities have been completed under our joint development plans by 2031. We may terminate the agreement if Suncor fails to make required payments under the Suncor License Agreement. Suncor may terminate the agreement for convenience upon 90 days' notice.

**Government Regulation**

***Environmental Regulation***

Our business and the businesses of the customers who license our technology are subject to various international, national, and regional laws and regulations relating to the production of renewable fuels, the protection of the environment and in support of the ethanol industry at large. These laws, their underlying regulatory requirements, and their enforcement, some of which are described below, impact our existing and potential business operations by imposing restrictions on our, our customers' and our partners':

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• existing and proposed business operations or the need to install enhanced or additional pollution controls;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• need to obtain and comply with permits and authorizations;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• liability for exceeding applicable permit limits or legal requirements; and

------

<u>[**Table of Contents**](#ib82e114cd19f45afae73e7a64e42f208_1390)</u>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• specifications related to the ethanol we market and produce.

GHG emissions are subject to environmental laws and regulations in the various jurisdictions in which we and our customers have operations. In the normal course of business, we and our customers and partners may be involved in legal proceedings under the Comprehensive Environmental Response, Compensation, and Liability Act, the Resource Conservation and Recovery Act, and similar environmental laws across the globe relating to the designation of certain sites for investigation or remediation with respect to environmental risks.

Some of our and our customers' operations are within jurisdictions that have or are developing regulatory regimes governing emissions of GHGs, including CO2. These include existing coverage under the European Union Emission Trading System, the California cap and trade scheme, India's Performance, Achieve and Trade scheme, South Africa's Trade Exposure and Greenhouse Gas Benchmark Regulations, the Tokyo Cap-and-Trade Program, China's Emission Trading Scheme and any potential expansions of these policies or related policies. In addition, the EPA requires mandatory reporting of GHG emissions and is regulating GHG emissions for new construction and major modifications to existing facilities.

Increased public concern surrounding the emission of GHGs may result in more international, national, or regional requirements to reduce or mitigate the effects of GHG emissions. While carbon reduction legislation will support the business case for implementing carbon capture technology, we cannot predict the manner or extent to which such legislation may affect our customers and partners and ultimately help or harm our business.

Our business could be affected in the future by additional international, national, and regional regulation, pricing of GHG emissions or other climate change legislation, regulation, or agreements. It is difficult at this time to estimate the likelihood of passage, or predict the potential impact, of any additional legislation, regulations or agreements. Potential consequences of new obligations could include increased technology, transportation, material, and administrative costs and may require us to make additional investments in our operations. As we continue distributing our technology to our target markets, international, national, or regional government entities may seek to impose regulations or competitors may seek to influence regulations through lobbying efforts.

***Fuel Ethanol Regulation***

There are various governmental programs and policies across the world that affect the supply and demand for ethanol and to which a significant percentage of our customers and partners are sensitive. For instance, in the United States, the federal government mandates the use of a certain amount of renewable fuels under the Renewable Fuel Standard II, or RFS II, and the Environmental Protection Agency has the authority to take measures with respect to RFS II that can have the effect of increasing or decreasing the overall volume of ethanol in the U.S. Currently, LanzaTech-derived ethanol from industrial emissions does not qualify as a Renewable Identification Number generating fuel under the US RFS II program. Furthermore, the recent United States-Mexico-Canada Agreement maintains the duty-free access of U.S. agricultural commodities, including ethanol, into Canada and Mexico and may have the effect of increasing the trading volume of ethanol throughout North America more broadly. Comparable international, U.S. federal and state regulatory and trading policies will affect the supply of ethanol for potential customers and partners within our target markets.

***Chemical Regulation***

There are important regulatory issues related to approval of chemicals from new pathways and approvals for import and use of genetically modified microorganisms ("GMM"). While specific requirements differ by jurisdiction, there are common elements across countries and regions such as chemical safety in production and end-use; required testing and data; process characterization; and following proper notification procedures. While chemically identical to existing and regulated chemicals, governments often require similar approval processes for new production routes such as those prescribed by the US Toxic Substances Control Act and the EU Registration, Evaluation, Authorisation and Restriction of Chemicals program. Further, the import and use of GMM such as biocatalysts in chemical production is governed by many of these same, as well as additional, laws and regulations. So far, we have received approximately 20 approvals or exemptions for use of our biocatalysts in the USA, China, India, Canada, Austria, Belgium, and Japan. As each jurisdiction has their own unique requirements for approval, our overall strategy for approval has included the use of external experts and consultants to accelerate our approval

------

<u>[**Table of Contents**](#ib82e114cd19f45afae73e7a64e42f208_1390)</u>

processes. Chemicals from new pathways is still an emerging area in legislation, where regulations are evolving to align with global best practices.

**Our People & Culture**

LanzaTech is a woman-led company. The core of who we are is based on a strong foundation of values. All team members are trained on how these fit into our day-to-day operations with our teammates and customers.

As of December 31, 2022, we had over 365 full-time equivalent employees working for LanzaTech in the United States, China, India, the United Kingdom, the European Union and New Zealand. None of our employees has engaged in any labor strikes. We have no collective bargaining agreements with our employees. We consider our relationship with our employees to be positive and have not experienced any major labor disputes.

**Facilities**

LanzaTech's global headquarters and R&D center are co-located at the Illinois Science + Technology Park research campus in Skokie, Illinois. The facility houses LanzaTech's state-of-the-art laboratories dedicated to synthetic biology, product synthesis, and analytics.

**Board Composition**

The LanzaTech Board directs the management of LanzaTech's business and affairs, as provided by Delaware law, and conducts its business through meetings of the Board and its standing committees. The LanzaTech Board consists of seven members. Dr. Holmgren serves as chair of the Board. The primary responsibilities of the Board are to provide risk oversight and strategic guidance to LanzaTech and to counsel and direct LanzaTech's management. The Board meets on a regular basis and will convene additional meetings, as required.

The LanzaTech Board is divided into three classes, with only one class of directors being elected in each year and each class serving a three-year term. Nigel Gormly, Jennifer Holmgren and Nimesh Patel are currently Class I drectors; Barbara Byrne and Gary Rieschel are currently Class II directors; and Jim Messina and Dorri McWhorter are currently Class III directors. Each Class I director has a term that expires at LanzaTech's 2024 annual meeting of stockholders, each Class II director has a term that expires at LanzaTech's 2025 annual meeting of stockholders, and each Class III director has a term that expires at LanzaTech's 2026 annual meeting of stockholders, or in each case until their respective successors are duly elected and qualified, or until their earlier resignation, removal or death.

**Independence of Directors**

LanzaTech adheres to the rules of Nasdaq in determining whether a director is independent. The Nasdaq listing standards generally define an "independent director" as a person who is not an executive officer or employee, or who does not have a relationship which, in the opinion of the company's board of directors, would interfere with the exercise of independent judgment in carrying out his or her responsibilities as a director. Our board of directors has determined that Nigel Gormly, Barbara Byrne, Jim Messina, Dorri McWhorter and Gary Rieschel are independent directors of LanzaTech. LanzaTech's independent directors have regularly scheduled meetings at which only independent directors are present.

The board recognizes the importance of appointing a strong lead independent director to maintain a counterbalancing structure to ensure the board functions in an appropriately independent manner. Jim Messina serves as our lead independent director. Our lead independent director's responsibilities include, among other things:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• presiding at all meetings of the board in the absence of, or upon the request of, the Chairperson of the board;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• lead regular executive sessions of the independent members of the board;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• call special meetings of the New LanzaTech Board as necessary to address important or urgent LanzaTech issues;

------

<u>[**Table of Contents**](#ib82e114cd19f45afae73e7a64e42f208_1390)</u>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• call meetings of the non-employee or independent members of the board, with appropriate notice;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• advise the Nominating and Governance Committee and the Chairperson of the board on the membership of the various board committees and the selection of committee chairpersons;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• serve as principal liaison between the non-employee and independent members of the board, as a group, the Chief Executive Officer of New LanzaTech, and the Chairperson of the board, as necessary;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• engage when necessary and appropriate, after consultation with the Chairperson of the board and the Chief Executive Officer, as the liaison between the board and the New LanzaTech shareholders and other stakeholders; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• foster open dialogue and constructive feedback among the independent directors.

**Board Leadership Structure and Role in Risk Oversight**

The Board recognizes that the leadership structure and combination or separation of the Chief Executive Officer and chairperson roles is driven by the needs of LanzaTech at any point in time. As a result, no policy exists requiring combination or separation of leadership roles, and our governing documents do not mandate a particular structure. This has allowed the Board the flexibility to establish the most appropriate structure for LanzaTech at any given time.

The LanzaTech Board oversees the risk management activities designed and implemented by its management. The LanzaTech Board does not have a standing risk management committee, but rather executes its oversight responsibility both directly and through its standing committees. The LanzaTech Board also considers specific risk topics, including risks associated with LanzaTech's strategic initiatives, business plans and capital structure. LanzaTech's management, including its executive officers, are primarily responsible for managing the risks associated with operation and business of the company and providing appropriate updates to the LanzaTech Board and the audit committee. The LanzaTech Board delegates to the audit committee oversight of its risk management process, and LanzaTech's other board committees also consider risks as they perform their respective committee responsibilities. All board committees report to the LanzaTech Board as appropriate, including, but not limited to, when a matter rises to the level of a material or enterprise risk.

**Board Committees of LanzaTech's Board of Directors**

LanzaTech has an audit committee, a nominating and governance committee and a compensation committee. In addition, from time to time, special committees may be established under the direction of the LanzaTech Board when necessary to address specific issues. Copies of each board committee's charter are posted on our website. Our website and the information contained on, or that can be accessed through, such website are not deemed to be incorporated by reference in, and are not considered part of, this prospectus.

Dorri McWhorter is an "audit committee financial expert" within the meaning of SEC regulations.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• pre-approving audit and non-audit services to be performed by the independent registered public accounting firm.

**Nominating and Governance Committee**

LanzaTech's nominating and governance committee consists of Nigel Gormly, Dorri McWhorter and Jim Messina. Jim Messina serves as the chairperson of LanzaTech's nominating and governance committee. Each of Nigel Gormly, Dorri McWhorter and Jim Messina is independent under Nasdaq listing standards.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• identifying and recommending candidates for membership on the Board;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• reviewing and recommending LanzaTech's corporate governance guidelines and policies;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• overseeing the process of evaluating the performance of the Board;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• assisting the Board on corporate governance matters; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• reviewing proposed waivers of our Code of Conduct and Ethics for directors and executive officers.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• reviewing LanzaTech's overall compensation philosophy.

**Code of Ethics and Code of Conduct and Ethics**

LanzaTech has adopted a Code of Conduct and Ethics that applies to all officers, directors and employees. The Code of Conduct and Ethics codifies the business and ethical principles that govern all aspects of our business, reflecting our commitment to this culture of honesty, integrity and accountability. In addition to following the Code

------

<u>[**Table of Contents**](#ib82e114cd19f45afae73e7a64e42f208_1390)</u>

of Conduct and Ethics, officers, directors and employees are expected to seek guidance in situations where there is a question regarding compliance issues, whether with the letter or the spirit of our policies and applicable laws. LanzaTech's Code of Conduct and Ethics applies to all of the executive officers, directors and employees of LanzaTech and its subsidiaries. We will provide, without charge, upon request, copies of the Code of Ethics. Our Code of Conduct and Ethics is available on our website.

***Narrative to Summary Compensation Table***

*Base Salaries*

Dr. Holmgren's annual base salary for 2022 was $525,000.

Mr. Trukenbrod's annual base salary for 2022 was initially $375,000, and was increased to $390,000 effective as of February 6, 2022.

Dr. Simpson's annual base salary for 2022 was $325,000, and was increased to $338,000, effective from February 6, 2022 to December 31, 2022.

*Bonuses*

In 2022, Dr. Holmgren, Mr. Trukenbrod and Dr. Simpson each earned a discretionary bonus.

*Equity Compensation*

Although LanzaTech does not have a formal policy with respect to the grant of equity incentive awards to its executive officers, or any formal equity ownership guidelines applicable to them, LanzaTech generally uses equity incentive awards to compensate its executive officers in the form of initial grants in connection with the commencement of employment and also at various other times during their employment. Accordingly, the LanzaTech Board, upon the recommendation of its compensation committee, periodically reviews the equity incentive compensation of LanzaTech's executive officers and from time to time has granted equity incentive awards to them in the form of stock options and restricted stock awards. No equity incentive awards were granted to Lanza Tech's named executive officers in 2022.

***Executive Employment Agreements and Other Arrangements***

*Dr. Jennifer Holmgren*

LanzaTech entered into an employment agreement with Dr. Holmgren in April 2010, which was subsequently amended. The employment agreement provides for Dr. Holmgren's at-will employment as LanzaTech's Chief Executive Officer and provides for an initial base salary, bonus target and equity award. Dr. Holmgren's salary and bonus target were revised most recently as of May 17, 2021.

Under the terms of her employment agreement, in the event Dr. Holmgren's employment is terminated without "Cause" (as defined in Dr. Holmgren's employment agreement), LanzaTech will be obligated to pay her an amount equal to six months of her then-current base salary, payable in substantially equal installments in accordance with LanzaTech's standard payroll practices. Notwithstanding the foregoing, in the event that such severance constitutes "nonqualified deferred compensation" within the meaning of Section 409A of the Code, then such severance shall not commence payment until the 60th day following Dr. Holmgren's "separation from service" within the meaning of Section 409A of the Code. The severance payments, and accelerated vesting terms described above in connection with a termination without Cause following a Change in Control, are subject to Dr. Holmgren's timely execution of a release agreement in form and content commercially reasonable.

On December 20, 2022, LanzaTech entered into an employment agreement with Dr. Holmgren, which became effective as of the Closing of the Business Combination (the "Holmgren Agreement"). The Holmgren Agreement provides for Dr. Holmgren's at-will employment as New LanzaTech's Chief Executive Officer and provides for an annual base salary of $750,000 and an initial annual bonus target of 100% of Dr. Holmgren's base salary. Pursuant to the agreement, LanzaTech granted Dr. Holmgren an initial equity award following the Closing consisting of (i) restricted stock units with a targeted value of $1,500,000 at grant, and (ii) a stock option to purchase a number of shares with a targeted value of $1,500,000 at grant and with a per share exercise price no less than the fair market

------

<u>[**Table of Contents**](#ib82e114cd19f45afae73e7a64e42f208_1390)</u>

value of a share on the date of grant. Subject to Dr. Holmgren's continued service, the initial equity award will vest in substantially equal installments over three years and will be subject to the terms of the 2023 Plan. Contingent upon the Closing, Dr. Holmgren will also be eligible for a one-time award of restricted stock units with a targeted value of $13,000,000 at grant. This award will be subject to both (i) a time-based vesting component (annual vesting over three years) and (ii) a performance-based vesting component (the 20-day average closing price of a share of New LanzaTech's common stock must reach $11.50 on or after the 151st day following, and within five years of, the Closing), and will vest on the first date both requirements are satisfied.

Under the terms of the Holmgren Agreement, in the event Dr. Holmgren's employment is terminated without "Cause" or Dr. Holmgren resigns for "Good Reason" (in each case as defined in the Holmgren Agreement), New LanzaTech is obligated to pay Dr. Holmgren (i) a lump sum payment equal to 18 months of her then-current base salary; (ii) an annual bonus (if any) for the year in which the termination occurs, equal to the annual bonus Dr. Holmgren would have received for that year based on actual performance and pro-rated based on the number of days she was employed during the relevant year; and (iii) if Dr. Holmgren is eligible for and timely elects COBRA coverage, up to 18 months of the portion of Dr. Holmgren's COBRA premium attributable to the employer contributions LanzaTech would have paid had Dr. Holmgren remained employed. Additionally, if Dr. Holmgren's employment is terminated without Cause or for Good Reason during the period beginning 30 days prior to a "Corporate Transaction" (as defined in the Holmgren Agreement) and ending 24 months following a Corporate Transaction, the amount of the lump sum payment described in clause (i) will be increased from 18 months to 24 months of her then-current base salary, and 50% of Dr. Holmgren's stock options which are outstanding as of the Closing will immediately vest.

The severance payments and accelerated vesting terms described above are subject to Dr. Holmgren's execution of a release agreement in a form provided by LanzaTech. Upon the adoption of the Severance Plan (as defined below), the terms of that plan will override the severance described above in clauses (i) through (iii) to the extent that plan's benefit is at least equal to the severance described above in clauses (i) through (iii). Dr. Holmgren's severance benefit under the Severance Plan is expected to be identical to what is described in clauses (i) through (iii) above.

*Geoff Trukenbrod*

LanzaTech entered into an employment agreement with Mr. Trukenbrod, effective as of May 29, 2021. The employment agreement provides for Mr. Trukenbrod's at-will employment as LanzaTech's Chief Financial Officer and provides for an annual base salary of $375,000 and an annual bonus of up to 40% of his then-current base salary. Mr. Trukenbrod was also awarded a $30,000 bonus in connection with the execution of his employment agreement, $15,000 of which was paid at the time of execution of such agreement and $15,000 of which was paid six months thereafter. In addition, LanzaTech awarded Mr. Trukenbrod an option to purchase 1,006,176 shares of common stock.

Under the terms of his employment agreement, in the event Mr. Trukenbrod's employment is terminated without "Cause" (as defined in Mr. Trukenbrod's employment agreement) or he resigns for "Good Reason" (as defined in Mr. Trukenbrod's employment agreement), LanzaTech will be obligated to (i) pay Mr. Trukenbrod an amount equal to six months of his then-current base salary, payable on LanzaTech's normal payroll schedule, (ii) subsidize Mr. Trukenbrod's continuation coverage under the Consolidated Omnibus Budget Reconciliation Act for a period of six months, and (iii) accelerate the vesting of any outstanding equity that would have vested in the 24-month period following Mr. Trukenbrod's termination. The severance payments and accelerated vesting terms described above are subject to Mr. Trukenbrod's execution of a waiver and release agreement in a form acceptable to LanzaTech for its senior executives.

On December 21, 2022, LanzaTech entered into a new employment agreement with Mr. Trukenbrod, which became effective as of the Closing of the Business Combination (the "Trukenbrod Agreement"). The Trukenbrod Agreement provides for Mr. Trukenbrod's at-will employment as LanzaTech's Chief Financial Officer and provides for an annual base salary of $425,000 and an initial annual bonus target of 70% of Mr. Trukenbrod's base salary. Pursuant to the agreement, LanzaTech granted Mr. Trukenbrod an initial equity award following the Closing consisting of (i) restricted stock units with a targeted value of $350,000 at grant, and (ii) a stock option to purchase a

------

<u>[**Table of Contents**](#ib82e114cd19f45afae73e7a64e42f208_1390)</u>

number of shares with a targeted value of $350,000 at grant and with a per share exercise price no less than the fair market value of a share on the date of grant. Subject to Mr. Trukenbrod's continued service, the initial equity award will vest in substantially equal installments over three years and will be subject to the terms of the 2023 Plan. Contingent upon the Closing, Mr. Trukenbrod will also be eligible for a one-time award of restricted stock units with a targeted value of $1,400,000 at grant. This award will be subject to both (i) a time-based vesting component (annual vesting over three years) and (ii) a performance-based vesting component (the 20-day average closing price of a share of common stock must reach $11.50 on or after the 151st day following, and within five years of, the Closing), and will vest on the first date both requirements are satisfied.

Under the terms of the Trukenbrod Agreement, in the event Mr. Trukenbrod's employment is terminated without "Cause" or Mr. Trukenbrod resigns for "Good Reason" (in each case, as defined in the Trukenbrod Agreement), LanzaTech will be obligated to pay Mr. Trukenbrod (i) a lump sum payment equal to 12 months of his then-current base salary; (ii) an annual bonus (if any) for the year in which the termination occurs, equal to the annual bonus Mr. Trukenbrod would have received for that year based on actual performance and pro-rated based on the number of days he was employed during the relevant year; and (iii) if Mr. Trukenbrod is eligible for and timely elects COBRA coverage, up to 12 months of the portion of Mr. Trukenbrod's COBRA premium attributable to the employer contributions LanzaTech would have paid had Mr. Trukenbrod remained employed. In addition, following a termination without "Cause" or a resignation for "Good Reason", the number of shares subject to stock options that remain outstanding as of immediately prior to the Closing, that would have vested in the 24-month period following such a termination, shall immediately vest. Notwithstanding the foregoing, if Mr. Trukenbrod's employment is terminated without Cause or for Good Reason during the period beginning 30 days prior to a "Corporate Transaction" (as defined in the Trukenbrod Agreement) and ending 24 months following a Corporate Transaction, the amount of the lump sum payment described in clause (i) will be increased from 12 months to 18 months of his then-current base salary.

The severance payments and accelerated vesting terms described above are subject to Mr. Trukenbrod's execution of a release agreement in a form provided by LanzaTech. Upon the adoption of the Severance Plan, the terms of that plan will override the severance described above in clauses (i) through (iii) to the extent that plan's benefit is at least equal to the severance described above in clauses (i) through (iii). Mr. Trukenbrod's severance benefit under the Severance Plan is expected to be identical to what is described in clauses (i) through (iii) above.

*Dr. Sean Simpson*

We entered into an offer letter with Dr. Simpson in November 2013, which was subsequently amended. The offer letter provided for Dr. Simpson's at-will employment as LanzaTech's Chief Science Officer and provided for an initial base salary and bonus target.

On January 2, 2023, we entered into a Transition Letter with Dr. Simpson (the "Transition Letter"), pursuant to which Dr. Simpson resigned from his positions as Chief Scientific Officer and as a member of the LanzaTech Board, effective as of January 1, 2023. In connection with Dr. Simpson's resignation and subject to Dr. Simpson complying with all other terms of the Transition Letter (including executing and not revoking the release of certain claims), he will receive a $1,500,000 payment in a single lump sum within 45 days of the Closing.

As provided by the terms of the Transition Agreement, LanzaTech and Dr. Simpson entered into a consulting agreement (the "Consulting Agreement"), pursuant to which Dr. Simpson will serve as a consultant to LanzaTech from January 1, 2023, through January 1, 2025, unless terminated by us or Dr. Simpson pursuant to the terms of the Consulting Agreement. Dr. Simpson's unvested equity awards will continue to vest so long as he remains a consultant to LanzaTech.

***Equity Incentive and Other Compensation Plans***

*Incentive Plan*

On December 23, 2022, the AMCI Board approved the 2023 Plan, which was approved by the AMCI stockholders on February 6, 2023, and became effective as of the consummation of the Business Combination.

AMCI initially reserved 19,622,273 shares of common stock for issuance under the 2023 Plan (the "Share Reserve"). In addition, such aggregate number of shares will automatically increase on January 1 of each year commencing on January 1, 2024, before the expiration of the 2023 Plan, in an amount equal to 3% of the total number of shares of New LanzaTech's capital stock outstanding on December 31 of the preceding year, unless the Board acts prior to January 1st of a given year to provide that the increase for such year will be a lesser number. The maximum aggregate number of shares which may be issued thereunder pursuant to incentive stock options ("ISOs") is 760,000,000 shares.

Shares issued under the 2023 Plan include authorized but unissued or reacquired shares of common stock. Any shares of common stock underlying any awards that are forfeited, cancelled, reacquired by New LanzaTech prior to vesting, expired (whether voluntarily or involuntarily), satisfied without the issuance of shares, withheld upon exercise of a stock option or settlement of an award to cover the exercise price or tax withholding, surrendered pursuant to an exchange, or otherwise terminated (other than by exercise) shall again be available for grant and issuance under the 2023 Plan; shall be deemed not to have been issued for purposes of determining the maximum aggregate number of shares that may be issued under the 2023 Plan; and shall not reduce the Share Reserve. With respect to awards that will or may be settled in cash, only shares actually issued pursuant to such awards are not available under the 2023 Plan; all remaining shares under such awards are available for future grant under the 2023 Plan. If any shares that actually have been issued under the 2023 Plan pursuant to an award are forfeited back to or reacquired by New LanzaTech pursuant to the failure to meet a contingency or condition required to vest such shares in the grantee, a right of first refusal, a forfeiture provision, or repurchase by New LanzaTech, then the shares that are forfeited or reacquired will revert to and again become available for future grant and issuance under the 2023

------

<u>[**Table of Contents**](#ib82e114cd19f45afae73e7a64e42f208_1390)</u>

Plan. Shares underlying any substitute awards that New LanzaTech grants to employees, directors or consultants of a business that is acquired by New LanzaTech do not count against the Share Reserve.

Plan Administration

The Board administers the 2023 Plan, and is authorized to delegate any or all of its powers under the 2023 Plan to one or more committees. The Board or committee(s) administering the 2023 Plan are referred to herein as the "Administrator." The Board is permitted to delegate to one or more officers the power to grant awards to its employees and officers and to exercise such other powers under the 2023 Plan as theBoard or committee(s) may determine, subject to certain limitations.

Awards

Under the 2023 Plan, the Administrator has the authority to award nonstatutory stock options ("NSOs"), ISOs, stock appreciation rights ("SARs"), restricted stock, restricted stock units ("RSUs"), unrestricted stock, performance awards and other stock-based awards or cash incentives. All awards are granted pursuant to an award agreement. Awards other than ISOs can be granted to employees, directors and consultants, but ISOs can be granted only to employees.

The Administrator has the authority to set the terms of all awards, including the vesting schedule, restrictions and restriction periods, repurchase provisions, rights of first refusal, forfeiture provisions, form of payment (cash, shares, or other consideration) upon exercise or settlement of the award, payment contingencies, and satisfaction of any performance goals. Each award agreement must specify any circumstances under which awards may be forfeited.

*Stock Options and SARs*. With respect to stock options and SARs, the Administrator determines the exercise price applicable thereto within the terms and conditions of the 2023 Plan; provided that, the exercise price per share subject to a stock option or SAR cannot be less than 100% of the fair market value of the common stock on the date of grant, unless the Board expressly determines otherwise and such stock option or SAR complies with applicable law, including Section 409A of the Code to the extent applicable. Notwithstanding the foregoing, stock options may be granted with a per share exercise price, other than as required above, as a substitution for a stock option or SAR in accordance with and pursuant to Section 424 of the Code, in the case of an ISO, and pursuant to Section 409A of the Code, in the case of a NSO. The Administrator also has authority to determine the term of stock options and SARs granted under the 2023 Plan, up to a maximum period of 10 years. The Administrator may, but is not required to, permit a grantee to exercise any part or all of his or her stock options prior to full vesting. In no event may a stock option be exercised beyond the expiration of its term. Payment for shares issued upon the exercise of a stock option may be made by (1) cash; (2) check; (3) to the extent permitted under applicable law, delivery of a promissory note with such recourse, interest, security, redemption, and other provisions as the Administrator determines to be appropriate (subject to the provisions of Section 153 of the Delaware General Corporation Law and any other applicable law); (4) cancellation of indebtedness; (5) other previously owned shares that have a fair market value on the date of surrender equal to the aggregate exercise price of the shares as to which the stock option is exercised; (6) a cashless exercise; (7) such other consideration and method of payment permitted under applicable law; or (8) any combination of the foregoing methods of payment. The 2023 Plan does not permit the repricing of options or SARs without shareholder approval.

*Tax Limitations on ISOs*. The aggregate fair market value, determined at the time of grant, of shares of common stock with respect to ISOs that are exercisable for the first time by an optionholder during any calendar year under all stock plans maintained by New LanzaTech may not exceed $100,000. Options or portions thereof that exceed such limit are generally treated as NSOs. No ISO may be granted to any person who, at the time of the grant, owns or is deemed to own more than 10% of the total combined voting power of all classes of New LanzaTech's stock or any affiliates of New LanzaTech unless (1) the option exercise price is at least 110% of the fair market value of the stock subject to the option on the date of grant, and (2) the option is not exercisable after the expiration of five years from the date of grant.

*Restricted Stock*. Except as otherwise provided in an award agreement, if a grantee of restricted stock terminates employment or service during the applicable restriction period, New LanzaTech has the right to repurchase all or

------

<u>[**Table of Contents**](#ib82e114cd19f45afae73e7a64e42f208_1390)</u>

part of the shares of restricted stock still subject to restriction from the grantee at the issue price or at another stated or formula price (or to require forfeiture if such shares of restricted stock were issued at no cost). Additionally, unless otherwise determined by the Administrator, grantees of restricted stock are entitled to receive all dividends and other distributions paid with respect to their shares of restricted stock, subject to such terms and conditions as the Administrator may determine.

*Restricted Stock Units*. An RSU may be settled in any form specified by the Administrator in the award agreement, including delivery of stock, cash, or a combination of cash and stock as deemed appropriate by the Administrator. The Administrator may, but need not, provide that grantees of RSUs are paid or accrue dividend equivalent payments on each date that dividends are paid with respect to New LanzaTech's common stock prior to the settlement of their RSUs, subject to such terms and conditions as the Administrator may determine. The treatment of any dividends or dividend equivalents shall be set forth in the award agreement at the time the award is granted.

*Performance Awards*. The 2023 Plan permits the grant of performance-based stock and cash awards that may vest or become earned and paid contingent upon the attainment of performance goals during a designated performance period, as determined by the Administrator and set forth in the applicable award agreement. Performance goals may be based on a company-wide basis, with respect to one or more business units, divisions, subsidiaries, or business segments, and in either absolute terms or relative to the performance of one or more comparable companies or the performance of one or more relevant indices, and may be based on financial performance, achievement of strategic objectives, or any other organizational goals, all as determined by the Administrator. At the expiration of the performance period, the Administrator shall evaluate the performance award holder's and/or New LanzaTech's performance in light of any performance goals for such performance award, and shall determine the number of shares (or other applicable payment measures) which have been earned.

*Other Awards*. The Board may issue other forms of awards, which may, but are not required to be, valued in whole or in part by reference to, or otherwise based on, New LanzaTech common stock. The Board hassole and complete discretion to determine the persons to whom and the time or times at which such other awards are granted, the number of shares of New LanzaTech common stock (or the cash equivalent thereof) to be granted and all other terms and conditions of such other awards. Such awards may be granted either alone or in conjunction with other awards granted under the 2023 Plan.

Transferability

Under the 2023 Plan, awards generally are not transferable, but the Administrator may provide that an award is transferable by will, by the laws of descent and distribution, or as permitted by applicable law. A grantee must satisfy all applicable federal, state and local or other income and employment tax withholding obligations before New LanzaTech recognizes ownership of shares under an award (or other consideration payable pursuant to the award).

Corporate Transactions and Recapitalizations

In the event of a "Corporate Transaction" (as defined in the 2023 Plan), each outstanding award is treated as the Administrator determines. The Administrator has the right to (1) accelerate the vesting of any or all outstanding stock options and SARs, in whole or in part; (2) make non-forfeitable any or all outstanding restricted stock or RSUs, in whole or in part; (3) cancel for no consideration any stock option or SAR that is not exercised as of the effective time of the Corporate Transaction; or (4) cancel or redeem awards in exchange for cash or another form of consideration, including substitute awards in respect of the capital stock of a successor corporation, all subject to any limitations imposed by applicable law and provided that, if the fair market value of common stock on the date of the Corporate Transaction does not exceed the exercise price of any option or SAR, the Administrator may cancel that stock option or SAR without any payment of consideration. The Administrator is not obligated to treat all stock awards or portions of stock awards in the same manner and is not obligated to take the same actions with respect to all participants.

In the event a successor or acquiring corporation (if any) refuses to assume, convert, replace, or substitute awards pursuant to a Corporate Transaction, such awards will have their vesting accelerate as to all shares subject to

------

<u>[**Table of Contents**](#ib82e114cd19f45afae73e7a64e42f208_1390)</u>

such awards (and any applicable right of repurchase fully lapse) immediately prior to the Corporate Transaction. In addition, in the event a successor or acquiring corporation (if any) refuses to assume, convert, replace, or substitute awards pursuant to a Corporate Transaction, the Administrator will notify the grantee that such award will be exercisable for a period of time determined by the Administrator in its sole discretion, and such award will terminate upon the expiration of such period.

Separately, in the event of a stock split or other change in the capital structure of New LanzaTech, the 2023 Plan provides for appropriate adjustments, as applicable, to the maximum number and class of shares reserved for issuance under the 2023 Plan, the ISO limit, and the class and number of shares and exercise price or purchase price of outstanding awards under the 2023 Plan.

Plan Amendment or Termination

The Board has the authority to amend, suspend, or terminate the 2023 Plan, although certain material amendments require the approval of New LanzaTech's stockholders. In no event will any amendment increase the maximum number of shares of common stock with respect to which awards may be granted under the 2023 Plan without stockholder approval. No awards are permitted to be granted after the tenth anniversary of the earlier of (i) the date the Board adopts the 2023 Plan and (ii) the date New LanzaTech's stockholders approve the 2023 Plan, unless sooner terminated.

The Administrator has the authority to amend, modify or terminate any outstanding award, but the grantee will be required to consent to such action unless the amendment, modification or termination would not materially and adversely affect the grantee's rights under the 2023 Plan, the change is permitted in connection with specified corporate transactions or capitalization adjustments, or the change is required or advisable for New LanzaTech, the 2023 Plan or the award to satisfy applicable law or accounting standards.

*Annual Bonus Plan*

On February 8, 2023, the Board adopted an annual bonus plan which became effective upon the completion of the Business Combination. The form of annual bonus plan is attached as Exhibit 10.30 to the registration statement of which this prospectus forms a part.

*Executive Severance Plan*

On February 8, 2023, the Board adopted an executive severance plan (the "Severance Plan") which became effective upon the completion of the Business Combination. Under the Severance Plan, qualifying employees who satisfy conditions set forth in the plan (other than Ms. Holmgren) will be entitled to receive 12 months' base salary, in the case of a Qualifying Termination, or 18 months' base salary, in the case of a Corporate Transaction Termination (in each case, as defined in the Severance Plan).

If a stock option under the LanzaTech 2006 Share Option Scheme, LanzaTech 2008 Share Option Scheme or LanzaTech NZ, Inc. 2011 Stock Plan expires or is cancelled or terminated (in whole or in part), or if shares of common stock are withheld upon exercise of a stock option under the LanzaTech NZ, Inc. 2011 Stock Plan to cover the exercise price or tax withholding, in each case during the period beginning on October 1, 2020 and ending on October 31, 2021, then the shares of common stock subject to such stock options (which amount shall not exceed 5,074,626 shares of common stock) shall become available for issuance under the 2019 Plan. The maximum number of shares of common stock that may be issued pursuant to the exercise of ISOs shall not exceed 5,906,033 shares, including, to the extent permitted by Section 422 of the Code, any shares that return to the 2019 Plan as described above.

Plan Administration

The LanzaTech Board administers the 2019 Plan and may delegate any or all of its powers under the plan to one or more of its committees. Subject to the terms of the 2019 Plan, the LanzaTech Board had the authority to set the terms of all awards.

Awards

The LanzaTech Board may grant awards of nonstatutory and incentive stock options and restricted stock under the 2019 Plan. All awards are granted pursuant to an award agreement. Awards other than ISOs may be granted to employees, directors, and consultants. ISOs may be granted only to employees. The LanzaTech Board determines the exercise price for a stock option within the terms and conditions of the 2019 Plan; *provided*, that the exercise price per share subject to an option cannot be less than 100% of the fair market value of common stock on the date of grant. Options granted under the 2019 Plan become exercisable at the rate specified by the LanzaTech Board in the award agreement. The award agreement specifies circumstances under which awards may be forfeited. The LanzaTech Board determines the term of stock options granted under the 2019 Plan, generally, up to a maximum of 10 years.

Any shares of LanzaTech's common stock awarded under any restricted stock award agreement may be subject to forfeiture to LanzaTech in accordance with a vesting schedule determined by the LanzaTech Board and award agreements for restricted stock will be subject to restrictions imposed by the LanzaTech Board, as it deems appropriate. Generally, if a grantee of restricted stock terminates employment or service during the applicable restriction period, LanzaTech has the right to repurchase from the grantee all or part of the shares of restricted stock still subject to restriction at the issue price or at another stated or formula price.

Corporate Transactions

The 2019 Plan provides that in the event of a "Change in Control" (as defined in the 2019 Plan), each outstanding award will be treated as the LanzaTech Board determines. The LanzaTech Board may (1) accelerate the vesting and/or exercisability of any or all outstanding stock options, in whole or in part; (2) make non-forfeitable any or all outstanding restricted stock awards, in whole or in part; (3) cancel or redeem awards in exchange for cash or another form of consideration, including cancelling for no consideration the portion of an option for which the fair market value on the date of the "Change in Control" does not exceed the exercise price; or (4) provide that the acquiring corporation will assume or continue the awards or substitute the awards for awards with respect to the acquiror's shares.

Certain stock options and restricted stock awards granted in November of 2020, and one restricted stock award granted in April of 2021, provide for accelerated vesting upon certain events that qualify as a "Liquidity Event" (as defined in the applicable award agreements, with respect to stock options and restricted stock awards respectively), unless the LanzaTech Board determines that such event is not a Liquidity Event.

Plan Amendment or Termination

The LanzaTech Board has the authority to alter, amend, suspend or terminate the 2019 Plan in whole or in part; *provided*, that the LanzaTech Board will obtain stockholder approval of any plan amendment to the extent necessary to comply with applicable law, rule, or regulation. In no event will any amendment increase the maximum number of shares of common stock with respect to which awards may be granted under the 2019 Plan without stockholder approval. The LanzaTech Board may amend, modify, or terminate any outstanding award, but the grantee will be required to consent to such action unless the amendment, modification, or termination would not adversely affect the grantee's rights under the 2019 Plan or the change is permitted in connection with a Change in Control or capitalization adjustments.

**CERTAIN RELATIONSHIPS AND RELATED PARTY TRANSACTIONS** 

**Policies and Procedures for Related Party Transactions** 

Upon consummation of the Business Combination, the Board adopted a written Related Party Transactions Policy that sets forth LanzaTech's policies and procedures regarding the notification, review, approval, ratification and disclosure of "related party transactions." For purposes of LanzaTech's policy, a "related party transaction" is a transaction, arrangement or relationship (or any series of similar transactions, arrangements or relationships) in which LanzaTech or any of its subsidiaries are participants involving an amount that exceeds $120,000, in which any "related person" has or will have a direct or indirect material interest.

Transactions involving compensation for services provided to LanzaTech as an employee or director will not be considered related party transactions under this policy. A "related person" is any executive officer, director, nominee to become a director, a holder of more than 5% of any class of LanzaTech's voting securities, including any of their immediate family members and affiliates, including entities owned or controlled by such persons, and any entity that employs any of the foregoing persons, of which any of the foregoing persons is a general partner, officer or serves in a similar position, or in which any of the foregoing persons has a 10% percent or greater beneficial ownership interest.

Under the policy, the related person in question or, in the case of transactions with a holder of more than 5% of any class of LanzaTech's voting securities, any director or employee with knowledge of a proposed transaction, must present information regarding the proposed related party transaction to the audit committee of the Board for review. To identify related party transactions in advance, LanzaTech will rely on information supplied by its executive officers, directors and certain significant stockholders.

The audit committee will approve only those transactions that it determines are in LanzaTech's best interests. The transactions described below under the subheadings "Pre-Business Combination AMCI Related Party Transactions" and "Legacy LanzaTech Related Party Transactions" were entered into prior to the adoption of the Related Party Transactions Policy.

Pursuant to the Registration Rights Agreement, we granted the parties thereto certain customary registration rights with respect to certain shares of common stock and warrants.

In addition, the Registration Rights Agreement provides that the Sponsor, then-holders of all outstanding shares of AMCI Class B common stock, and certain holders of shares of Legacy LanzaTech capital stock will be subject to certain restrictions on transfer with respect to their shares of common stock and LanzaTech warrants. Such restrictions will end (i) with respect to the Sponsor and the holders of AMCI Class B common stock, on the earlier of (a) the date that is one year following the closing of the Business Combination, (b) such date upon which the closing price per share of common stock equals or exceeds $12.00 per share for any 20 trading days within any 30 day trading period commencing at least 150 days after the closing of the Business Combination and (c) the date on which LanzaTech completes a liquidation, merger, capital stock exchange, reorganization or other similar transaction after the Business Combination that results in all of LanzaTech's stockholders having the right to exchange their shares of common stock for cash, securities or other property, and (ii) with respect to the holders of shares of Legacy LanzaTech capital stock, on the date that is six months following the closing of the Business Combination.

***Indemnification Agreements***

In connection with consummating the Business Combination, LanzaTech entered into customary indemnification agreements with the directors and executive officers of LanzaTech following the Business Combination.

**Pre-Business Combination AMCI Related Party Transactions** 

***Founder Shares***

On January 29, 2021, the Sponsor paid $25,000, or approximately $0.005 per share, to cover certain offering costs in consideration for 5,031,250 shares common stock. In March 2021, the Sponsor transferred all of the founder shares held by it to members of the AMCI Board, management team and persons or entities affiliated with AMCI Group. Such shares are fully paid. On May 14, 2021, certain of AMCI's initial stockholders forfeited an aggregate of 718,750 founder shares, resulting in an aggregate of 4,312,500 founder shares outstanding. On September 17, 2021, the over-allotment option granted in connection with AMCI's IPO expired unexercised, resulting in the 562,500 additional founder shares being forfeited.

***Agreements with Anchor Investors***

In accordance with the terms of the letter agreements entered into between AMCI and certain qualified institutional buyers or institutional accredited investors who purchased units in the IPO, including entities affiliated with Apollo Capital Management, L.P., Adage Capital Partners, L.P., Shaolin Capital Management, LLC and Aristeia Capital, LLC, (the "Anchor Investors"), certain of AMCI's initial stockholders agreed to sell an aggregate of 780,000 founder shares to the Anchor Investors concurrently with the Closing. The Anchor Investors were introduced to AMCI through Evercore, in Evercore's capacity as underwriter of AMCI's IPO. AMCI determined that the fair value of these founder shares was approximately $6.5 million (or approximately $8.35 per share) using a Monte Carlo simulation. AMCI recognized the excess fair value of these founder shares, over the price sold to the

------

<u>[**Table of Contents**](#ib82e114cd19f45afae73e7a64e42f208_1390)</u>

Anchor Investors, as an expense of the IPO resulting in a charge against the carrying value of AMCI Class A common stock subject to possible redemption. None of the Anchor Investors are "related persons" with respect to AMCI or LanzaTech as such term is defined in Item 404(a) of Regulation S-K.

***Private Placement Warrants***

Simultaneously with the closing of the IPO, the Sponsor purchased an aggregate of 3,500,000 Private Placement Warrants, each exercisable to purchase one share of AMCI Class A common stock at $11.50 per share, at a price of $1.00 per warrant, or $3,500,000 in the aggregate.

The Private Placement Warrants are not redeemable by AMCI so long as they are held by the initial purchasers or their permitted transferees. The initial purchasers, or their permitted transferees, have the option to exercise the Private Placement Warrants on a cashless basis. If the Private Placement Warrants are held by holders other than initial purchasers or their permitted transferees, the Private Placement Warrants will be redeemable and exercisable by the holders on the same basis as the warrants included in the units sold in the IPO. Otherwise, the Private Placement Warrants have terms and provisions that are identical to those of the warrants sold as part of the units in the IPO.

If the Private Placement Warrants are held by holders other than the Sponsor or its permitted transferees, the Private Placement Warrants will be redeemable in all redemption scenarios and exercisable by the holders on the same basis as the warrants included in the units sold in the IPO.

***Private Placement***

As part of the Private Placement, AMCI Group, LLC Series 35, an entity in which Hans Mende, a director of AMCI, holds voting and investment control, subscribed for 1,700,000 shares of AMCI Class A common stock for an aggregate purchase price of $17,000,000. In connection with the consummation of the Business Combination, all of the issued and outstanding shares of AMCI Class A common stock, including the shares of AMCI Class A common stock issued to AMCI Group, LLC Series 35, became shares of common stock. AMCI Group, LLC Series 35 is a member of the Sponsor and a beneficial owner of more than 5% of AMCI's currently outstanding securities.

***Sponsor Support Agreement and Sponsor Letter Agreement***

In connection with the IPO, the Sponsor and the other AMCI Insiders entered into a letter agreement with AMCI, pursuant to which they agreed to (i) waive their redemption rights with respect to any founder shares and public shares they hold in connection with the completion of AMCI's initial business combination, (ii) waive their redemption rights with respect to any founder shares and public shares they hold in connection with a stockholder vote to approve an amendment to AMCI's amended and restated certificate of incorporation to modify the substance or timing of its obligation to redeem 100% of its public shares if AMCI had not consummated an initial business combination within 24 months from the closing of the IPO or with respect to any other material provisions relating to stockholders' rights or pre-initial business combination activity and (iii) waive their rights to liquidating distributions from the Trust Account with respect to any founder shares they hold if AMCI failed to complete an initial business combination within 24 months from the closing of the IPO or during any extended period of time as a result of an amendment to our amended and restated certificate of incorporation.

In connection with the execution of the Merger Agreement, the Sponsor and the holders of all of the shares of AMCI Class B common stock, including the AMCI Insiders, entered into the Sponsor Support Agreement with AMCI and Legacy LanzaTech, pursuant to which each AMCI Insider agreed, among other things, to: (i) vote all the AMCI Shares held by such AMCI Insider (a) in favor of each of the condition precedent proposals and (b) against a business combination not relating to the Business Combination and any other action that would reasonably be expected to (x) materially impede, interfere with, delay, postpone or adversely affect the Business Combination or any of the other transactions contemplated by the Merger Agreement, (y) to the knowledge of such AMCI Insider, result in a material breach of any covenant, representation or warranty or other obligation or agreement of AMCI under the Merger Agreement or (z) result in a material breach of any covenant, representation or warranty or other obligation or agreement contained in the Sponsor Support Agreement; (ii) irrevocably waive any anti-dilution right or other protection with respect to the shares of AMCI Class B common stock that would result in the AMCI Class

------

<u>[**Table of Contents**](#ib82e114cd19f45afae73e7a64e42f208_1390)</u>

B common stock converting into AMCI Class A common stock at a ratio greater than one-for-one; and (iii) not to elect to redeem their respective shares of common stock of AMCI in connection with the Business Combination. In addition, under the Sponsor Support Agreement, the AMCI Insiders agreed to forfeit, on a pro rata basis, the at-risk founder shares in the event that there was an excess redemption percentage of the issued and outstanding shares of AMCI Class A common stock.

***Administrative Service Fee***

Subsequent to the closing of the IPO, AMCI agreed to pay its Sponsor $10,000 per month for office space and secretarial and administrative services provided to members of the management team.

***LanzaJet Shareholder Loan***

On November 9, 2022, Legacy LanzaTech and the other LanzaJet shareholders entered into the LanzaJet Note Purchase Agreement, pursuant to which FPF, a wholly owned subsidiary of LanzaJet, will issue, from time to time, the LanzaJet Notes in an aggregate principal amount of up to $147.0 million, comprised of approximately $113.5 million aggregate principal amount of 6.00% Senior Secured Notes due December 31, 2043 and $33.5 million aggregate principal amount of 6.00% Subordinated Secured Notes due December 31, 2043. Legacy LanzaTech has committed to purchase $5.5 million of Subordinated Secured Notes in a funding expected to occur on May 1, 2023. The Senior Secured Notes are secured by a security interest over substantially all assets of FPF, and both the Senior Secured Notes and the Subordinated Secured Notes are secured by a security interest over all intellectual property owned or in-licensed by LanzaJet. LanzaJet also provides a guarantee of any costs and expenses required to complete the LanzaJet Freedom Pines Demonstration Facility and achieve commercial operation.

Each purchaser of LanzaJet Notes under the LanzaJet Note Purchase Agreement is also entitled to receive a warrant for the right to purchase 575 shares of common stock of LanzaJet for each $10,000 of Notes purchased by such purchaser (which, in the case of the Company, will be equal to a right to purchase 316,250 shares of common stock of LanzaJet).

The LanzaJet Note Purchase Agreement may be amended with the approval of holders of FPF and all of the holders of the LanzaJet Notes. Upon an event of default under the LanzaJet Note Purchase Agreement, each purchaser may accelerate its own LanzaJet Notes. Enforcement against the collateral securing the LanzaJet Notes requires the approval of certain holders as specified in the LanzaJet Notes.

**DESCRIPTION OF SECURITIES** 

*The following summary of the material terms of the common stock, preferred stock and our Private Placement Warrants is not intended to be a complete summary of the rights and preferences of such securities, and is qualified by reference to the applicable warrant agreement and to our Charter and Bylaws, which are exhibits to the registration statement of which this prospectus forms a part. We urge you to read the applicable warrant agreement and our Charter and Bylaws in their entirety for a complete description of the rights and preferences of our securities.* 

**Authorized and Outstanding Stock**

The Charter authorizes the issuance of 420,000,000 shares, consisting of 400,000,000 shares of common stock, $0.0001 par value per share, and 20,000,000 shares of preferred stock, $0.0001 par value per share. As of the date of this prospectus, there were 196,222,737 shares of common stock outstanding. No shares of preferred stock are currently outstanding.

***Common Stock***

The Charter provides the following with respect to the rights, powers, preferences and privileges of the common stock.

*Voting Power*

Except as otherwise required by law or as otherwise provided in any certificate of designation for any series of preferred stock, the holders of shares of common stock possess all voting power for the election of LanzaTech's directors and all other matters requiring stockholder action. Holders of shares of common stock are entitled to one vote for each share held on all matters to be voted on by stockholders.

*Dividends*

Holders of shares of common stock will be entitled to receive such dividends, if any, as may be declared from time to time by the Board in its discretion out of funds legally available therefor. AMCI has not historically paid any cash dividends on the common stock to date and we do not intend to pay cash dividends in the foreseeable future. Any payment of cash dividends in the future will be dependent upon LanzaTech's revenues and earnings, if any, capital requirements and general financial conditions. In no event will any stock dividends or stock splits or combinations of stock be declared or made on shares of common stock unless the shares of common stock at the time outstanding are treated equally and identically.

*Liquidation, Dissolution and Winding Up*

In the event of LanzaTech's voluntary or involuntary liquidation, dissolution, distribution of assets or winding-up, the holders of shares of common stock will be entitled to receive an equal amount per share of all of LanzaTech's assets of whatever kind available for distribution to stockholders, after the rights of the holders of the preferred stock have been satisfied.

*Preemptive or Other Rights*

The LanzaTech stockholders have no preemptive or other subscription rights. No sinking fund provisions are applicable to the common stock.

***Preferred Stock***

The Charter provides that shares of preferred stock may be issued from time to time in one or more series. The Board is authorized to fix the voting rights, if any, designations, powers, preferences, the relative, participating, optional or other special rights and any qualifications, limitations and restrictions thereof, applicable to the shares of each series. The Board will be able to, without stockholder approval, issue shares of preferred stock with voting and other rights that could adversely affect the voting power and other rights of the holders of the shares of common

------

<u>[**Table of Contents**](#ib82e114cd19f45afae73e7a64e42f208_1390)</u>

stock and could have anti-takeover effects. The ability of the Board to issue shares of preferred stock without stockholder approval could have the effect of delaying, deferring or preventing a change of control of LanzaTech or the removal of existing management.

***Registration Rights***

AMCI, certain of the Legacy LanzaTech stockholders and AMCI Stockholders entered into a Registration Rights Agreement, pursuant to which, among other things, such stockholders were granted certain registration rights with respect to certain shares of securities held by them.

***Anti-Takeover Provisions***

*Charter and Bylaws*

Among other things, the Charter and Bylaws:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• permit the Board to issue up to 20,000,000 shares of preferred stock, with any rights, preferences and privileges as they may designate, including the right to approve an acquisition or other change of control;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• provide that the number of directors of LanzaTech may be changed only by resolution of the Board;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• provide that, subject to the rights of any series of preferred stock to elect directors, directors may be removed only with cause by the holders of at least 66⅔% of all of LanzaTech's then-outstanding shares of the capital stock entitled to vote generally at an election of directors;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• provide that all vacancies, including newly created directorships, may, except as otherwise required by law, be filled by the affirmative vote of a majority of directors then in office, even if less than a quorum;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• provide that stockholders seeking to present proposals before a meeting of stockholders or to nominate candidates for election as directors at a meeting of stockholders must provide advance notice in writing, and also specify requirements as to the form and content of a stockholder's notice;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• provide that special meetings of LanzaTech's stockholders may be called by the Board pursuant to a resolution adopted by a majority of the Board;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• provide that the Board will be divided into three classes of directors, with the classes to be as nearly equal as possible, and with the directors serving three-year terms, therefore making it more difficult for stockholders to change the composition of the Board; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• do not provide for cumulative voting rights, therefore allowing the holders of a majority of the shares of common stock entitled to vote in any election of directors to elect all of the directors standing for election, if they should so choose.

The combination of these provisions will make it more difficult for the existing stockholders to replace the Board as well as for another party to obtain control of LanzaTech by replacing the Board. Because the

Board has the power to retain and discharge its officers, these provisions could also make it more difficult for existing stockholders or another party to effect a change in management. In addition, the authorization of undesignated preferred stock makes it possible for the Board to issue shares of preferred stock with voting or other rights or preferences that could impede the success of any attempt to change the control of LanzaTech.

These provisions are intended to enhance the likelihood of continued stability in the composition of the Board and its policies and to discourage coercive takeover practices and inadequate takeover bids. These provisions are also designed to reduce LanzaTech's vulnerability to hostile takeovers and to discourage certain tactics that may be used in proxy fights. However, such provisions could have the effect of discouraging others from making tender offers for LanzaTech's shares and may have the effect of delaying changes in its control or management. As a consequence, these provisions may also inhibit fluctuations in the market price of LanzaTech's Common Stock.

*Certain Anti-Takeover Provisions of Delaware Law*

LanzaTech is subject to the provisions of Section 203 of the DGCL, which prevents certain Delaware corporations, under certain circumstances, from engaging in a "business combination" with:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a stockholder who owns 15% or more of our outstanding voting stock (otherwise known as an "interested stockholder");

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• an affiliate of an interested stockholder; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• an associate of an interested stockholder, for three years following the date that the stockholder became an interested stockholder.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• A "business combination" includes a merger or sale of more than 10% of a corporation's assets.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• However, the above provisions of Section 203 would not apply if:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the relevant board of directors approves the transaction that made the stockholder an interested stockholder prior to the date of the transaction;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• after the completion of the transaction that resulted in the stockholder becoming an interested stockholder, that stockholder owned at least 85% of the corporation's voting stock outstanding at the time the transaction commenced, other than statutorily excluded shares of common stock; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• on or subsequent to the date of the transaction, the initial business combination is approved by the board of directors and authorized at a meeting of the corporation's stockholders, and not by written consent, by an affirmative vote of at least two-thirds of the outstanding voting stock not owned by the interested stockholder.

These provisions may have the effect of delaying, deferring, or preventing changes in control of LanzaTech.

**Warrants**

***Public Warrants***

Each Public Warrant entitles the registered holder to purchase one share of common stock at a price of $11.50 per share, subject to adjustment as discussed below, at any time commencing 30 days after the completion of the Business Combination. Pursuant to the warrant agreement, a Public Warrant holder may exercise its Public Warrants only for a whole number of shares of common stock. This means that only a whole Public Warrant may be exercised at any given time by a Public Warrant holder. No fractional Public Warrants were issued upon separation of AMCI's units and only whole Public Warrants will trade. The Public Warrants will expire five years after the Closing, at 5:00 p.m., New York City time, or earlier upon redemption or liquidation.

We are not obligated to deliver any shares of common stock pursuant to the exercise of a Public Warrant and will have no obligation to settle such Public Warrant exercise unless a registration statement under the Securities Act with respect to the shares of common stock underlying the Public Warrants is then effective and a prospectus relating thereto is current, subject to satisfaction of our obligations described below with respect to registration. No Public Warrant will be exercisable and we will not be obligated to issue shares of common stock upon exercise of a Public Warrant unless the common stock issuable upon such Public Warrant exercise has been registered, qualified or deemed to be exempt under the securities laws of the state of residence of the registered holder of the Public Warrants. In the event that the conditions in the two immediately preceding sentences are not satisfied with respect to a Public Warrant, the holder of such Public Warrant will not be entitled to exercise such Public Warrant and such Public Warrant may have no value and expire worthless. In no event will we be required to net cash settle any warrant. In the event that a registration statement is not effective for the exercised Public Warrants, the purchaser of a unit containing such Public Warrant will have paid the full purchase price for the unit solely for the share of common stock underlying such unit.

------

<u>[**Table of Contents**](#ib82e114cd19f45afae73e7a64e42f208_1390)</u>

We have agreed that as soon as practicable, but in no event later than 15 business days after the Closing, we will use our best efforts to file with the SEC a registration statement covering the shares of common stock issuable upon exercise of the Public Warrants, to cause such registration statement to become effective and to maintain a current prospectus relating to those shares of common stock until the Public Warrants expire or are redeemed, as specified in the warrant agreement. We cannot assure you that we will be able to do so if, for example, any facts or events arise which represent a fundamental change in the information set forth in the registration statement or prospectus, the financial statements contained or incorporated by reference therein are not current or correct or the SEC issues a stop order. If a registration statement covering the shares of common stock issuable upon exercise of the Public Warrants is not effective by the 60th business day after the Closing, Public Warrant holders may, until such time as there is an effective registration statement and during any period when we have failed to maintain an effective registration statement, exercise warrants on a "cashless basis" in accordance with Section 3(a)(9) of the Securities Act or another exemption. Notwithstanding the above, if common stock is at the time of any exercise of a warrant not listed on a national securities exchange such that it satisfies the definition of a "covered security" under Section 18(b)(1) of the Securities Act, we may, at our option, require holders of Public Warrants who exercise their warrants to do so on a "cashless basis" in accordance with Section 3(a)(9) of the Securities Act and, in the event we so elect, we will not be required to file or maintain in effect a registration statement, and in the event we do not so elect, we will use our best efforts to register or qualify the shares under applicable blue sky laws to the extent an exemption is not available. In such event, each holder would pay the exercise price by surrendering the Public Warrants for that number of shares of common stock equal to the lesser of (A) the quotient obtained by dividing (x) the product of the number of shares of common stock underlying the warrants, multiplied by the excess of the "fair market value" (defined below) less the exercise price of the warrants by (y) the fair market value and (B) 0.361. The "*fair market value*" as used in this paragraph shall mean the volume weighted average price of the common stock for the 10 trading days ending on the trading day prior to the date on which the notice of exercise is received by the warrant agent.

*Redemption of Public Warrant when the price per share of common stock equals or exceeds $18.00.*

Once the Public Warrants become exercisable, we may call the Public Warrants for redemption:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• in whole and not in part;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• at a price of $0.01 per warrant;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• upon a minimum of 30 days' prior written notice of redemption to each Public Warrant holder; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• if, and only if, the closing price of common stock equals or exceeds $18.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) for any 20 trading days within a 30-trading day period commencing once the Public Warrants become exercisable and ending three trading days before we send the notice of redemption to the Public Warrant holders.

We may not redeem the Public Warrants as described above unless a registration statement under the Securities Act covering the issuance of the common stock issuable upon exercise of the warrants is then effective and a current prospectus relating to those shares of common stock is available throughout the 30-day redemption period. If and when the Public Warrants become redeemable by us, we may exercise our redemption right even if we are unable to register or qualify the underlying securities for sale under all applicable state securities laws.

We have established the last of the redemption criteria discussed above to prevent a redemption call unless there is at the time of the call a significant premium to the Public Warrant exercise price. If the foregoing conditions are satisfied and we issue a notice of redemption of the Public Warrants, each Public Warrant holder will be entitled to exercise its Public Warrant prior to the scheduled redemption date. However, the price of the common stock may fall below the $18.00 redemption trigger price (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) as well as the $11.50 (for whole shares) warrant exercise price after the redemption notice is issued.

*Redemption of Public Warrants when the price per share of common stock equals or exceeds $10.00.*

Once the Public Warrants become exercisable, we may redeem the outstanding Public Warrants:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• in whole and not in part;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• at $0.10 per warrant upon a minimum of 30 days' prior written notice of redemption provided that holders will be able to exercise their warrants on a cashless basis prior to redemption and receive that number of shares determined by reference to the table below, based on the redemption date and the "fair market value" of the common stock except as otherwise described below; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• if, and only if, the closing price of the common stock equals or exceeds $10.00 per share (as adjusted for adjustments to the number of shares issuable upon exercise or the exercise price of a warrant as described below under the heading "— Anti-Dilution Adjustments") for any 20 trading days within the 30-trading day period ending three trading days before we send the notice of redemption to the Public Warrant holders.

Beginning on the date the notice of redemption is given until the Public Warrants are redeemed or exercised, holders may elect to exercise their Public Warrants on a cashless basis. The numbers in the table below represent the number of shares of common stock that a Public Warrant holder will receive upon such cashless exercise in connection with a redemption by New LanzaTech pursuant to this redemption feature, based on the "fair market value" of common stock on the corresponding redemption date (assuming holders elect to exercise their Public Warrants and such warrants are not redeemed for $0.10 per warrant), determined for these purposes based on volume weighted average price of common stock during the 10 trading days immediately following the date on which the notice of redemption is sent to the holders of Public Warrants, and the number of months that the corresponding redemption date precedes the expiration date of the warrants, each as set forth in the table below. We will provide the Public Warrant holders with the final fair market value no later than one business day after the 10-trading day period described above ends.

The share prices set forth in the column headings of the table below will be adjusted as of any date on which the number of shares issuable upon exercise of a Public Warrant or the exercise price of a Public Warrant is adjusted as set forth under the heading "— *Anti-Dilution Adjustments*" below. If the number of shares issuable upon exercise of a Public Warrant is adjusted, the adjusted share prices in the column headings will equal the share prices immediately prior to such adjustment, multiplied by a fraction, the numerator of which is the number of shares deliverable upon exercise of a Public Warrant immediately prior to such adjustment and the denominator of which is the number of shares deliverable upon exercise of a Public Warrant as so adjusted. The number of shares in the table below shall be adjusted in the same manner and at the same time as the number of shares issuable upon exercise of a Public Warrant. If the exercise price of a Public Warrant is adjusted, (a) in the case of an adjustment pursuant to the second paragraph under the heading "*— Other Terms*" below, the adjusted share prices in the column headings will equal the unadjusted share price multiplied by a fraction, the numerator of which is the higher of the Market Value and the Newly Issued Price as set forth under the heading "*— Other Terms*" and the denominator of which is $10.00 and (b) in the case of an adjustment pursuant to the second paragraph under the heading "*—Anti-Dilution*

*Adjustments*" below, the adjusted share prices in the column headings will equal the unadjusted share price less the decrease in the exercise price of a public warrant pursuant to such exercise price adjustment.

The exact fair market value and redemption date may not be set forth in the table above, in which case, if the fair market value is between two values in the table or the redemption date is between two redemption dates in the table, the number of shares of common stock to be issued for each Public Warrant exercised will be determined by a straight-line interpolation between the number of shares set forth for the higher and lower fair market values and the earlier and later redemption dates, as applicable, based on a 365 or 366-day year, as applicable. For example, if the volume weighted average price of common stock during the 10 trading days immediately following the date on which the notice of redemption is sent to the holders of the Public Warrants is $11.00 per share, and at such time there are 57 months until the expiration of the warrants, holders may choose to, in connection with this redemption feature, exercise their Public Warrants for 0.277 shares of common stock for each whole public warrant. For an example where the exact fair market value and redemption date are not as set forth in the table above, if the volume weighted average price of common stock during the 10 trading days immediately following the date on which the notice of redemption is sent to the holders of the Public Warrants is $13.50 per share, and at such time there are 38 months until the expiration of the Public Warrants, holders may choose to, in connection with this redemption feature, exercise their Public Warrants for 0.298 shares of common stock for each whole Public Warrant. In no event will the Public Warrants be exercisable on a cashless basis in connection with this redemption feature for more than 0.361 shares of common stock per warrant (subject to adjustment). Finally, as reflected in the table above, if the Public Warrants are out of the money and about to expire, they cannot be exercised on a cashless basis in connection

------

<u>[**Table of Contents**](#ib82e114cd19f45afae73e7a64e42f208_1390)</u>

with a redemption by us pursuant to this redemption feature, since they will not be exercisable for any shares of common stock.

This redemption feature differs from the typical warrant redemption features used in other blank check offerings, which typically only provide for a redemption of warrants for cash (other than the Private Placement Warrants) when the trading price for the underlying common stock exceeds $18.00 per share for a specified period of time. This redemption feature is structured to allow for all of the outstanding Public Warrants to be redeemed when the common stock is trading at or above $10.00 per share, which may be at a time when the trading price of the common stock is below the exercise price of the Public Warrants. We have established this redemption feature to provide us with the flexibility to redeem the Public Warrants without the warrants having to reach the $18.00 per share threshold set forth above under "— *Redemption of Public Warrants when the price per share of the common stock equals or exceeds $18*.*00*." Holders choosing to exercise their Public Warrants in connection with a redemption pursuant to this feature will, in effect, receive a number of shares for their Public Warrants based on an

option pricing model with a fixed volatility input. This redemption right provides us with an additional mechanism by which to redeem all of the outstanding Public Warrants, and therefore have certainty as to our capital structure as the Public Warrants would no longer be outstanding and would have been exercised or redeemed and we will be required to pay the redemption price to Public Warrant holders if we choose to exercise this redemption right and it will allow us to quickly proceed with a redemption of the Public Warrants if we determine it is in our best interest to do so. As such, we would redeem the Public Warrants in this manner when we believes it is in our best interest to update our capital structure to remove the Public Warrants and pay the redemption price to the Public Warrant holders.

As stated above, we can redeem the Public Warrants when the common stock is trading at a price starting at $10.00, which is below the exercise price of $11.50, because it will provide certainty with respect to our capital structure and cash position while providing Public Warrant holders with the opportunity to exercise their warrants on a cashless basis for the applicable number of shares. If we choose to redeem the Public Warrant when the common stock is trading at a price below the exercise price of the Public Warrants, this could result in the Public Warrant holders receiving fewer shares of common stock than they would have received if they had chosen to wait to exercise their Public Warrants for Common Stock if and when such Common Stock was trading at a price higher than the exercise price of $11.50.

No fractional shares of common stock will be issued upon exercise. If, upon exercise, a holder would be entitled to receive a fractional interest in a share, we will round down to the nearest whole number of the number of shares of common stock to be issued to the holder.

*Redemption Procedures*

A holder of a Public Warrant may notify us in writing in the event it elects to be subject to a requirement that such holder will not have the right to exercise such Public Warrant, to the extent that after giving effect to such exercise, such person (together with such person's affiliates), to the warrant agent's actual knowledge, would beneficially own in excess of 4.9% or 9.8% (as specified by the holder) of the common stock outstanding immediately after giving effect to such exercise.

*Anti-Dilution Adjustments*

If the number of outstanding shares of common stock is increased by a capitalization or share dividend payable in Common Stock, or by a split-up of shares of common stock or other similar event, then, on the effective date of such stock dividend, split-up or similar event, the number of shares of common stock issuable on exercise of each whole Public Warrant will be increased in proportion to such increase in the outstanding ordinary stock. A rights offering made to all or substantially all holders of common stock entitling holders to purchase common stock at a price less than the "historical fair market value" (as defined below) will be deemed a share dividend of a number of shares of common stock equal to the product of (i) the number of shares of common stock actually sold in such rights offering (or issuable under any other equity securities sold in such rights offering that are convertible into or exercisable for common stock) and (ii) one minus the quotient of (x) the price per share of common stock paid in such rights offering and (y) the historical fair market value. For these purposes, (a) if the rights offering is for

------

<u>[**Table of Contents**](#ib82e114cd19f45afae73e7a64e42f208_1390)</u>

securities convertible into or exercisable for common stock, in determining the price payable for Common Stock, there will be taken into account any consideration received for such rights, as well as any additional amount payable upon exercise or conversion and (b) "*historical fair market value*" means the volume weighted average price of common stock as reported during the 10 trading day period ending on the trading day prior to the first date on which the common stock trade on the applicable exchange or in the applicable market, regular way, without the right to receive such rights.

In addition, if we, at any time while the warrants are outstanding and unexpired, pay a dividend or make a distribution in cash, securities or other assets to the holders of shares of common stock on account of such shares (or other securities into which the warrants are convertible), other than (a) as described above, or (b) any cash dividends or cash distributions which, when combined on a per share basis with all other cash dividends and cash distributions paid on the common stock during the 365-day period ending on the date of declaration of such dividend or distribution does not exceed $0.50 (as adjusted to appropriately reflect any other adjustments and excluding cash dividends or cash distributions that resulted in an adjustment to the exercise price or to the number of shares of common stock issuable on exercise of each Public Warrant) but only with respect to the amount of the aggregate cash dividends or cash distributions equal to or less than $0.50 per share, then the warrant exercise price will be decreased, effective immediately after the effective date of such event, by the amount of cash and/or the fair market value of any securities or other assets paid on each share of common stock in respect of such event.

If the number of outstanding shares of common stock is decreased by a consolidation, combination, reverse stock split or reclassification of shares of common stock or other similar event, then, on the effective date of such consolidation, combination, reverse stock split, reclassification or similar event, the number of shares of common stock issuable on exercise of each Public Warrant will be decreased in proportion to such decrease in outstanding shares of common stock.

Whenever the number of shares of common stock purchasable upon the exercise of the Public Warrants is adjusted, as described above, the Public Warrant exercise price will be adjusted by multiplying the Public Warrant exercise price immediately prior to such adjustment by a fraction (x) the numerator of which will be the number of shares of common stock purchasable upon the exercise of the Public Warrants immediately prior to such adjustment, and (y) the denominator of which will be the number of shares of common stock so purchasable immediately thereafter.

In case of any reclassification or reorganization of the outstanding shares of common stock (other than those described above or that solely affects the par value of such shares of common stock), or in the case of any merger or consolidation of LanzaTech with or into another corporation (other than a consolidation or merger in which we are the continuing corporation and that does not result in any reclassification or reorganization of the outstanding shares of common stock), or in the case of any sale or conveyance to another corporation or entity of the assets or other property of LanzaTech as an entirety or substantially as an entirety in connection with which we are dissolved, the holders of the Public Warrants will thereafter have the right to purchase and receive, upon the basis and upon the terms and conditions specified in the Public Warrants and in lieu of the common stock immediately theretofore purchasable and receivable upon the exercise of the rights represented thereby, the kind and amount of shares of common stock or other securities or property (including cash) receivable upon such reclassification, reorganization, merger or consolidation, or upon a dissolution following any such sale or transfer, that the holder of the Public Warrants would have received if such holder had exercised their Public Warrants immediately prior to such event. However, if less than 70% of the consideration receivable by the holders of common stock in such a transaction is payable in the form of common stock in the successor entity that is listed for trading on a national securities exchange or is quoted in an established over-the-counter market, or is to be so listed for trading or quoted immediately following such event, and if the registered holder of the Public Warrant properly exercises the Public Warrant within 30 days following public disclosure of such transaction, the Public Warrant exercise price will be reduced as specified in the warrant agreement based on the Black-Scholes value (as defined in the warrant agreement) of the Public Warrant. The purpose of such exercise price reduction is to provide additional value to holders of the Public Warrants when an extraordinary transaction occurs during the exercise period of the Public Warrants pursuant to which the holders of the warrants otherwise do not receive the full potential value of the Public Warrants in order to determine and realize the option value component of the Public Warrant. This formula is to compensate the Public Warrant holder for the loss of the option value portion of the Public Warrant due to the

------

<u>[**Table of Contents**](#ib82e114cd19f45afae73e7a64e42f208_1390)</u>

requirement that the Public Warrant holder exercise the Public Warrant within 30 days of the event. The Black-Scholes model is an accepted pricing model for estimating fair market value where no quoted market price for an instrument is available.

*Other Terms*

The Public Warrants are issued in registered form under a warrant agreement between Continental Stock Transfer & Trust Company, as warrant agent, and us. The warrant agreement provides that the terms of the Public Warrants may be amended without the consent of any holder to cure any ambiguity or correct any defective provision, and that all other modifications or amendments will require the vote or written consent of the holders of at least 50% of the then outstanding Public Warrants, and, solely with respect to any amendment to the terms of the Private Placement Warrants, a majority of the then outstanding Private Placement Warrants.

The Public Warrants may be exercised upon surrender of the warrant certificate on or prior to the expiration date at the offices of the warrant agent, with the exercise form on the reverse side of the warrant certificate completed and executed as indicated, accompanied by full payment of the exercise price (or on a cashless basis, if applicable), by certified or official bank check payable to us, for the number of Public Warrants being exercised. The Public Warrant holders do not have the rights or privileges of holders of common stock and any voting rights until they exercise their Public Warrants and receive Common Stock. After the issuance of common stock upon exercise of the Public Warrants, each holder will be entitled to one vote for each share held of record on all matters to be voted on by stockholders.

No fractional shares will be issued upon exercise of the Public Warrants. If, upon exercise of the Public Warrants, a holder would be entitled to receive a fractional interest in a share, we will, upon exercise, round down to the nearest whole number of shares of common stock to be issued to the warrant holder.

***Private Placement Warrants***

Except as described below, the Private Placement Warrants have terms and provisions that are identical to those of the Public Warrants. The Private Placement Warrants (including the common stock issuable upon exercise of the Private Placement Warrants) will not be transferable, assignable or salable until 30 days after the Closing (except pursuant to limited exceptions to AMCI's officers and directors and other persons or entities affiliated with the initial purchasers of the Private Placement Warrants) and they will not be redeemable by us so long as they are held by the Sponsor or its permitted transferees. The Sponsor, or its permitted transferees, has the option to exercise the Private Placement Warrants on a cashless basis. If the Private Placement Warrants are held by holders other than the Sponsor or its permitted transferees, the Private Placement Warrants will be redeemable by us in all redemption scenarios and exercisable by the holders on the same basis as the Public Warrants.

If holders of the Private Placement Warrants elect to exercise them on a cashless basis, they would pay the exercise price by surrendering their warrants for that number of shares of common stock equal to the quotient obtained by dividing (x) the product of the number of shares of common stock underlying the warrants, multiplied by the excess of the "Sponsor fair market value" (defined below) over the exercise price of the warrants by (y) the Sponsor fair market value. For these purposes, the "*Sponsor fair market value*" shall mean the average reported closing price of the common stock for the 10 trading days ending on the third trading day prior to the date on which the notice of warrant exercise is sent to the warrant agent. The reason that these warrants will be exercisable on a cashless basis so long as they are held by the Sponsor and its permitted transferees is because if they remain affiliated with us, their ability to sell our securities in the open market will be significantly limited. We have policies in place that restrict insiders from selling our securities except during specific periods of time. Even during such periods of time when insiders will be permitted to sell our securities, an insider cannot trade in our securities if he or she is in possession of material non-public information. Accordingly, unlike public stockholders who could exercise their warrants and sell the common stock received upon such exercise freely in the open market in order to recoup the cost of such exercise, the insiders could be significantly restricted from selling such securities. As a result, we believe that allowing the holders to exercise such warrants on a cashless basis is appropriate.

AMCI's initial stockholders have agreed not to transfer, assign or sell any of the Private Placement Warrants (including the common stock issuable upon exercise of any of these warrants) until the date that is 30 days after the

------

<u>[**Table of Contents**](#ib82e114cd19f45afae73e7a64e42f208_1390)</u>

Closing, except that, among other limited exceptions, transfers can be made to AMCI's officers and directors and other persons or entities affiliated with the Sponsor.

**Forward Purchase Agreement**

On February 3, 2023, AMCI, Legacy LanzaTech and ACM entered into the Forward Purchase Agreement for an over-the-counter Equity Prepaid Forward Transaction (the "Forward Purchase Transaction"). For purposes of the Forward Purchase Agreement, ACM is referred to as the "Seller" and AMCI and LanzaTech are referred to as the "Counterparty" prior to and after the Business Combination, respectively. Pursuant to the terms of the Forward Purchase Agreement, the Seller purchased through a broker in the open market 5,916,514 shares of AMCI's common stock before the closing of the Business Combination (the "Closing") from holders of AMCI's common shares (other than AMCI), including from holders who had previously elected to redeem their shares (such purchased shares, and the successor shares following the Closing, the "Recycled Shares") in connection with the Business Combination pursuant to the redemption rights set forth in AMCI's Amended and Restated Certificate of Incorporation (such holders, "Redeeming Holders"). The aggregate total number of shares subject to the Forward Purchase Agreement (the "Number of Shares") is 10,000,000. The Number of Shares is subject to reduction following termination of the Forward Purchase Agreement with respect to the Recycled Shares as described under "Optional Early Termination" in the Forward Purchase Agreement. Unless in connection with an optional early termination, the Seller has agreed to hold the Recycled Shares in a bankruptcy remote special purpose vehicle for the benefit of the Counterparty. The Seller also may not beneficially own greater than 9.9% of our outstanding common shares.

In accordance with the Forward Purchase Agreement, the Seller was paid directly, out of the funds held in the Trust Account $60.1 million (the "Prepayment Amount").

We agreed to file a registration statement with the SEC registering the resale of the Recycled Shares and the Share Consideration (as defined below) (the "Registration Statement") under the Securities Act of 1933, within 45 days following the request of the Seller. From time to time following the Closing and only after the effectiveness of the Registration Statement (the "Registration Statement Effective Date"), the Seller may, at its discretion, provide a shortfall sale notice to the Counterparty without a payment obligation to the Counterparty (the "Shortfall Sales") until such time as the aggregate amount indicated on such shortfall sale notices equals $2,500,000 (the "Prepayment Shortfall"). The Prepayment Shortfall will increase by $7,500,000 if the Counterparty fails to repay to the Seller the Prepayment Shortfall in full within 30 days from the Closing. For 30 days following the Closing, the Seller will not sell any Recycled Shares at a price below $10.00 per share. The Counterparty has agreed that it will not issue any shares, or securities or debt that is convertible, exercisable or exchangeable into shares until the gross proceeds indicated in the shortfall sales notices equal the Prepayment Shortfall, except under certain circumstances as further described in the Forward Purchase Agreement. The Seller in its sole discretion may request warrants of the Counterparty exercisable for shares in an amount equal to (i) 10,000,000 shares less (ii) (a) the number of Recycled Shares at the outset of the Forward Purchase Transaction plus (b) the number of shares indicated on the shortfall sale notice by the Seller that reduces the Prepayment Shortfall (the "Shortfall Warrants"). The Shortfall Warrants will have an exercise price equal to the Reset Price.

The Seller may also, at its discretion and at any time, provide a notice under "OET Sales." The Seller may deliver an OET notice and return to the Counterparty the product of the Reset Price and the number of shares listed on the OET notice. Following the Closing, the reset price (the "Reset Price") will initially be the per share Redemption Price; provided, however, that the Reset Price may be reduced to any lower price at which the Counterparty sells, issues or grants any shares or securities convertible or exchangeable into shares (other than grants or issuances under the Counterparty's equity compensation plans or shares underlying warrants issued in connection with the Business Combination), subject to certain exceptions.

The maturity date will be the third anniversary of the Closing (the "Maturity Date"). Upon the occurrence of the Maturity Date, the Counterparty is obligated to pay to Seller an amount equal to the product of (1) (a) the lesser of the Maximum Number of Shares and 7,500,000 less (b) the number of Terminated Shares multiplied by (2) $2.00, or $3.25 if the Counterparty fails to repay to the Seller the Prepayment Shortfall in full within 30 days of the closing of the Business Combination (the "Maturity Consideration"). At the Maturity Date, the Counterparty will be entitled to

------

<u>[**Table of Contents**](#ib82e114cd19f45afae73e7a64e42f208_1390)</u>

deliver the Maturity Consideration to the Seller in cash or shares calculated based on the average daily VWAP Price over 30 trading days ending on the later of the Maturity Date and the date on which such shares are registered. The Maturity Date may be accelerated by Seller, at its discretion, if, among other termination events, following the Closing, the VWAP Price is below (i) if the Counterparty has not repaid the Prepayment Shortfall in full, then (a) $3.00 per Share for any 20 trading days during a 30 consecutive trading day-period that ends during the first 90 days after the date of the Forward Purchase Agreement, and (b) $6.00 per Share thereafter, and (b) if the Counterparty has repaid the Prepayment Shortfall in full, then (1) $2.00 per Share for any 50 trading days during a 60 consecutive trading day-period that ends during the first 90 days after the date of the Forward Purchase Agreement, and (2) $3.00 per share thereafter. In addition to the Prepayment Amount and the Maturity Consideration, on the Maturity Date, the Counterparty has agreed to pay to the Seller an amount equal to the product of (x) 500,000 and (y) the Redemption Price (the "Share Consideration").

The Forward Purchase Agreement may be terminated by any of the parties thereto if the resale registration statement is not declared effective within 105 days of the registration request (such event, an "Additional Termination Event").

The Counterparty has agreed to indemnify and hold harmless the Seller, its affiliates, assignees and other parties described therein (the "Indemnified Parties") from and against all losses, claims, damages and liabilities under the Forward Purchase Agreement (excluding liabilities relating to the manner in which Seller sells any shares it owns) and reimburse the Indemnified Parties for their reasonable expenses incurred in connection with such liabilities, subject to certain exceptions described therein, and has agreed to contribute to any amounts required to be paid by any Indemnified Parties if such indemnification is unavailable or insufficient to hold such party harmless.

**Limitations on Liability and Indemnification of Officers and Directors**

The DGCL authorizes corporations to limit or eliminate the personal liability of directors of corporations and their stockholders for monetary damages for breaches of directors' fiduciary duties, subject to certain exceptions. The Charter includes a provision that eliminates the personal liability of directors for damages for any breach of fiduciary duty as a director where, in civil proceedings, the person acted in good faith and in a manner that person reasonably believed to be in or not opposed to the best interests of LanzaTech or, in criminal proceedings, where the person had no reasonable cause to believe that his or her conduct was unlawful.

The Bylaws provide that we must indemnify and advance expenses to our directors and officers to the fullest extent authorized by the DGCL. We are also expressly authorized to carry directors' and officers' liability insurance providing indemnification for our directors, officers, and certain employees for some liabilities. We believe that these indemnification and advancement provisions and insurance are useful to attract and retain qualified directors and executive officers.

The limitation of liability, advancement and indemnification provisions in the Charter and Bylaws may discourage stockholders from bringing lawsuits against directors for breaches of their fiduciary duties. These provisions also may have the effect of reducing the likelihood of derivative litigation against directors and officers, even though such an action, if successful, might otherwise benefit us and our stockholders. In addition, your investment may be adversely affected to the extent we pay the costs of settlement and damage awards against directors and officer pursuant to these indemnification provisions.

There is currently no pending material litigation or proceeding involving any of our directors, officers, or employees for which indemnification is sought.

**Stockholders' Derivative Actions**

**MATERIAL U.S. FEDERAL INCOME AND ESTATE TAX CONSIDERATIONS**

The following discussion describes material United States federal income and estate tax considerations relating to the acquisition, ownership, and disposition of shares by a a non-U.S. holder (as defined below) that acquires our shares in this offering and holds them as a capital asset. This discussion is based on the tax laws of the United States, including the Code, Treasury regulations promulgated or proposed thereunder, and administrative and judicial interpretations thereof, all as in effect on the date hereof. These tax laws are subject to change, possibly with retroactive effect, and subject to differing interpretations that could affect the tax consequences described herein. This section does not address the treatment of a non-U.S. holder under the laws of any state, local or foreign taxing jurisdiction.

For purposes of this discussion, a "non-U.S. holder" is a beneficial owner of our shares that, for United States federal income tax purposes, is:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a non-resident alien individual;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•a foreign corporation;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•an estate the income of which is not subject to United States federal income taxation regardless of its source; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•a trust that does not have in effect a valid election under the Treasury regulations to be treated as a United States person and either (1) no court within the United States is able to exercise primary supervision over the trust's administration or (2) no United States person has the authority to control all substantial decisions of that trust.

This discussion does not address all aspects of United States federal income taxation that may be applicable to holders in light of their particular circumstances or status (including, for example, banks and other financial institutions, insurance companies, brokers and dealers in securities or currencies, traders that have elected to mark securities to market, partnerships or other pass-through entities, corporations that accumulate earnings to avoid United States federal income tax, tax-exempt organizations, pension plans, persons that hold our shares as part of a straddle, hedge or other integrated investment, persons subject to alternative minimum tax, certain United States expatriates, and foreign governments or agencies).

If a partnership (including any entity or arrangement treated as a partnership for United States federal income tax purposes) holds our shares, the tax treatment of a person treated as a partner in the partnership for United States federal income tax purposes generally will depend on the status of the partner and the activities of the partnership. Partnerships (and other entities or arrangements so treated for United States federal income tax purposes) and their partners should consult their own tax advisors.

***This discussion addresses only non-U.S. holders and does not discuss any tax considerations other than United States federal income tax and certain United States federal estate tax considerations. Prospective investors are urged to consult their own tax advisors regarding the United States federal, state, and local, and foreign tax consequences of the purchase, ownership, and disposition of our shares, including the effect of any applicable income or estate tax treaty.*** 

**Dividends** 

As discussed above, we have not paid and do not currently expect to pay dividends. If we do make a distribution of cash or property with respect to our shares, any such distribution generally will constitute a dividend for United States federal income tax purposes except as described below. Subject to the discussion below under "— FATCA Withholding" and "— Information Reporting and Backup Withholding," and except as described below, any such dividends paid to a non-U.S. holder generally will be subject to withholding tax at a 30% rate or at a lower rate under an applicable income tax treaty between the United States and the non-U.S. holder's country of residence. In order to receive a reduced treaty withholding tax rate, a non-U.S. holder must furnish to us or our paying agent a properly executed Internal Revenue Service

------

<u>[**Table of Contents**](#ib82e114cd19f45afae73e7a64e42f208_1390)</u>

Form W-8BEN or Form W-8BEN-E (or other applicable form) prior to payment of the dividend, certifying under penalties of perjury that the non-U.S. holder is entitled to a reduction in withholding under an applicable income tax treaty. A non-U.S. holder that holds our shares through a financial institution or other agent will be required to provide appropriate documentation to the financial institution or other agent, which then will be required to provide certification to us or our paying agent either directly or through other intermediaries. A non-U.S. holder that is eligible for a reduced rate of withholding tax pursuant to an income tax treaty may obtain a refund of any excess amounts withheld by filing a refund claim with the Internal Revenue Service.

If a dividend is "effectively connected" with the conduct of a trade or business in the United States of the non-U.S. holder (and, if an applicable income tax treaty so provides, attributable to a permanent establishment or fixed base maintained by the non-U.S. holder in the United States), the non-U.S. holder is exempt from the withholding tax described above provided that the holder has furnished to us or our paying agent an Internal Revenue Service Form W-8ECI (or applicable successor form), certifying under penalties of perjury that the dividend is effectively connected with the non-U.S. holder's conduct of a trade or business in the United States (and, if an applicable income tax treaty so provides, attributable to a permanent establishment or fixed base maintained in the United States). "Effectively connected" dividends will generally be subject to United States federal income tax at the rates that also apply to U.S. persons. A corporate non-U.S. holder may, under certain circumstances, be subject to an additional branch profits tax at a 30% rate (or at a lower rate under an applicable income tax treaty) with respect to its "effectively connected" dividends.

To the extent a distribution with respect to our shares exceeds our current or accumulated earnings and profits, as determined under United States federal income tax principles, the distribution will be treated, first, as a tax-free return of the non-U.S. holder's investment, up to the holder's adjusted tax basis in its shares, and, thereafter, as capital gain, which is subject to the tax treatment described below in "- Gain on Sale, Exchange or Other Taxable Disposition."

**Gain On Sale, Exchange or Other Taxable Disposition** 

Subject to the discussion below under "- FATCA Withholding" and "- Information Reporting and Backup Withholding," a non-U.S. holder generally will not be subject to United States federal income tax or withholding tax on gain realized upon a sale, exchange or other taxable disposition of shares (including a redemption, but only if the redemption would be treated as a sale or exchange rather than a distribution for United States federal income tax purposes) unless:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the gain is "effectively connected" with the conduct of a trade or business of the non-U.S. holder in the United States (and, if required by an applicable income tax treaty, the gain is attributable to a permanent establishment or fixed base maintained in the United States), in which case the non-U.S. holder generally will be subject to United States federal income tax on a net income basis with respect to such gain in the same manner as if such holder were a resident of the United States and, if the non-U.S. holder is a corporation for United States federal income tax purposes, may, under certain circumstances, be subject to an additional "branch profits tax" at a 30% rate (or at a lower rate under an applicable income tax treaty) on its "effectively connected" gains;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•the non-U.S. holder is an individual who is present in the United States for 183 or more days in the taxable year of the disposition and meets certain other conditions, in which case the non-U.S. holder generally will be subject to United States federal income tax at a 30% rate (or at a lower rate under an applicable income tax treaty) on the gain derived from the sale, which gain may be offset by U.S.-source capital losses for the year; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•we are or have been a "United States real property holding corporation" or USRPHC (as described below) at any time within the shorter of the five-year period preceding the disposition and the non-U.S. holder's holding period for our shares (the "relevant period") and the non-U.S. holder (i) disposes of our shares during a calendar year when our shares are no longer regularly traded on an established securities market or (ii) owned (directly, indirectly, and constructively) more than 5% of our shares at any time during the relevant period, in which case such a non-U.S. holder will be subject to tax on the gain on the disposition of

------

<u>[**Table of Contents**](#ib82e114cd19f45afae73e7a64e42f208_1390)</u>

shares generally as if the gain were effectively connected with the conduct of a trade or business in the United States, except that the "branch profits tax" will not apply.

We believe we currently are not, and we do not anticipate becoming, a USRPHC for United States federal income tax purposes. Generally, a corporation is a USRPHC only if the fair market value of its United States real property interests (as defined in the Code) equals or exceeds 50% of the sum of the fair market value of its worldwide real property interests and its other assets used or held for use in a trade or business.

**FATCA Withholding** 

Sections 1471 through 1474 of the Code and the Treasury regulations issued thereunder (commonly referred to as the Foreign Account Tax Compliance Act, or FATCA) impose a 30% withholding tax on dividends paid on our shares to, and (subject to the proposed Treasury Regulations discussed below) the gross proceeds derived from the sale or other disposition of our shares by, a foreign entity if the foreign entity is:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a "foreign financial institution" (as defined under FATCA) that does not furnish proper documentation, typically on IRS Form W-8BEN-E, evidencing either (i) an exemption from FATCA withholding or (ii) its compliance (or deemed compliance) with specified due diligence, reporting, withholding and certification obligations under FATCA or (iii) residence in a jurisdiction that has entered into an intergovernmental agreement with the United States relating to FATCA and compliance with the diligence and reporting requirements of the intergovernmental agreement and local implementing rules; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•a "non-financial foreign entity" (as defined under FATCA) that does not provide sufficient documentation, typically on IRS Form W-8BEN-E, evidencing either (i) an exemption from FATCA or (ii) adequate information regarding substantial United States beneficial owners of such entity (if any).

Withholding under FATCA generally applies to payments of dividends on our shares and to payments of gross proceeds from a sale or other disposition of our shares. Withholding agents may, however, rely on proposed U.S. Treasury Regulations that would no longer require FATCA withholding on payments of gross proceeds. A withholding agent such as a broker, and not LanzaTech, will determine whether or not to implement gross proceeds FATCA withholding.

If a dividend payment is subject to withholding both under FATCA and the withholding tax rules discussed above under "- Dividends," the withholding under FATCA may be credited against, and therefore reduce, such other withholding tax. Holders of shares should consult their own tax advisors regarding these requirements and whether they may be relevant to their ownership and disposition of the shares.

Under certain circumstances, a non-U.S. holder will be eligible for refunds or credits of withholding taxes imposed under FATCA by filing a United States federal income tax return. Prospective investors should consult their tax advisors regarding the effect of FATCA on their ownership and disposition of our shares.

**Information Reporting and Backup Withholding** 

Except as described below, a non-U.S. holder generally will be exempt from backup withholding and information reporting requirements with respect to dividend payments and the payment of the proceeds from the sale of our shares effected at a United States office of a broker, as long as the payor or broker does not have actual knowledge or reason to know that the holder is a United States person and the holder has furnished to the payor or broker:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a valid Internal Revenue Service Form W-8BEN or Form W-8BEN-E on which the non-U.S. holder certifies, under penalties of perjury, that it is a non-United States person; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•other documentation upon which it may rely to treat the payments as made to a non-United States person in accordance with Treasury regulations,

or the non-U.S. holder otherwise establishes an exemption.

------

<u>[**Table of Contents**](#ib82e114cd19f45afae73e7a64e42f208_1390)</u>

However, we must report annually to the Internal Revenue Service and to non-U.S. holders the amount of dividends paid to them and the tax withheld with respect to such dividends, regardless of whether withholding was required. Copies of the information returns reporting such dividends and withholding may also be made available to the tax authorities in the country in which the respective non-U.S. holder resides under the provisions of an applicable income tax treaty.

Payment of the proceeds from the sale of our shares effected at a foreign office of a broker generally will not be subject to information reporting or backup withholding. However, a sale of our shares by a non-U.S. holder that is effected at a foreign office of a broker will be subject to information reporting and backup withholding if:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the proceeds are transferred to an account maintained by the non-U.S. holder in the United States;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•the payment of proceeds or the confirmation of the sale is mailed to the non-U.S. holder at a United States address; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•the sale has some other specified connection with the United States as provided in the Treasury regulations,

unless the broker does not have actual knowledge or reason to know that the holder is a United States person and the documentation requirements described above are met or the non-U.S. holder otherwise establishes an exemption.

In addition, a sale of shares will be subject to information reporting if it is effected at a foreign office of a broker that is:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a United States person;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•a "controlled foreign corporation" for United States federal income tax purposes;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•a foreign person 50% or more of whose gross income is effectively connected with the conduct of a United States trade or business for a specified three-year period; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•a foreign partnership, if at any time during its tax year (a) one or more of its partners are "U.S. persons", as defined in U.S. Treasury regulations, who in the aggregate hold more than 50% of the income or capital interest in the partnership, or (b) such foreign partnership is engaged in the conduct of a trade or business in the United States,

unless the broker does not have actual knowledge or reason to know that the holder is a United States person and the documentation requirements described above are met or an exemption is otherwise established. Backup withholding will apply if the sale is subject to information reporting and the broker has actual knowledge that the holder is a United States person.

Backup withholding is not an additional tax. A non-U.S. holder generally may obtain a refund of any amounts withheld under the backup withholding rules that exceed the non-U.S. holder's income tax liability by timely filing a refund claim with the Internal Revenue Service.

**Federal Estate Taxes** 

The estates of nonresident alien decedents generally are subject to United States federal estate tax on property with a United States situs. Because we are a United States corporation, our shares will be United States situs property and therefore will be included in the taxable estate of a nonresident alien decedent at the time of the decedent's death, unless an applicable estate tax treaty between the United States and the decedent's country of residence provides otherwise. An estate tax credit is available to reduce the net tax liability of a nonresident alien's estate, but the estate tax credit for a nonresident alien is generally much smaller than the applicable credit for computing the estate tax of a United States resident. Nonresident aliens should consult their personal tax advisors regarding the United States federal estate tax consequences of owning our shares.

We will bear all costs, expenses and fees in connection with the registration of these securities, including with regard to compliance with state securities or "blue sky" laws. The selling stockholders will bear all commissions and discounts, if any, attributable to their sale of warrants or shares of common stock (as applicable).

We will not receive any proceeds from the sale of the Private Placement Warrants or of the common stock by the selling stockholders pursuant to this prospectus. The aggregate proceeds to the selling stockholders will be the purchase price of the common stock or warrants (as applicable) less any discounts and commissions borne by the selling stockholders.

The Private Placement Warrants and shares of common stock beneficially owned by the selling stockholders covered by this prospectus may be offered and sold from time to time by the selling stockholders. The term "selling stockholders" includes donees, pledgees, transferees or other successors in interest selling securities received after the date of this prospectus from a selling stockholder as a gift, pledge, partnership distribution or other transfer. The selling stockholders will act independently of us in making decisions with respect to the timing, manner and size of each sale. Such sales may be made on one or more exchanges or in the over-the-counter market or otherwise, at prices and under terms then prevailing or at prices related to the then current market price or in negotiated transactions. The selling stockholders may sell their shares of common stock or Private Placement Warrants by one or more of, or a combination of, the following methods:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• purchases by a broker-dealer as principal and resale by such broker-dealer for its own account pursuant to this prospectus;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• ordinary brokerage transactions and transactions in which the broker solicits purchasers;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• block trades in which the broker-dealer so engaged will attempt to sell the shares as agent but may position and resell a portion of the block as principal to facilitate the transaction;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• an over-the-counter distribution in accordance with the rules of Nasdaq;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• through trading plans entered into by a selling stockholder pursuant to Rule 10b5-1 under the Exchange Act, that are in place at the time of an offering pursuant to this prospectus and any applicable prospectus supplement hereto that provide for periodic sales of their securities on the basis of parameters described in such trading plans;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to or through underwriters, agents or broker-dealers;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• "at the market" offerings, as defined in Rule 415 under the Securities Act, at negotiated prices, at prices prevailing at the time of sale or at prices related to such prevailing market prices, including sales made

------

<u>[**Table of Contents**](#ib82e114cd19f45afae73e7a64e42f208_1390)</u>

directly on a national securities exchange or sales made through a market maker other than on an exchange or other similar offerings through sales agents;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• privately negotiated transactions

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• options transactions;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• through a combination of any of the above methods of sale; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any other method permitted pursuant to applicable law.

In addition, any securities that qualify for sale pursuant to Rule 144 may be sold under Rule 144 rather than pursuant to this prospectus.

To the extent required, this prospectus may be amended or supplemented from time to time to describe a specific plan of distribution. In connection with distributions of the common stock, Private Placement Warrants or otherwise, the selling stockholders may enter into hedging transactions with broker-dealers or other financial institutions. In connection with such transactions, broker-dealers or other financial institutions may engage in short sales of common stock or Private Placement Warrants in the course of hedging the positions they assume with selling stockholders. The selling stockholders may also sell shares of common stock or Private Placement Warrants short and redeliver the shares to close out such short positions. The selling stockholders may also enter into option or other transactions with broker-dealers or other financial institutions which require the delivery to such broker-dealer or other financial institution of securities offered by this prospectus, which securities such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction). The selling stockholders may also pledge shares of common stock or Private Placement Warrants to a broker-dealer or other financial institution, and, upon a default, such broker-dealer or other financial institution may effect sales of the pledged securities pursuant to this prospectus (as supplemented or amended to reflect such transaction).

A selling stockholder may enter into derivative transactions with third parties, or sell securities not covered by this prospectus to third parties in privately negotiated transactions. If an applicable prospectus supplement indicates, in connection with those derivatives, the third parties may sell shares of common stock or Private Placement Warrants covered by this prospectus and the applicable prospectus supplement, including in short sale transactions. If so, the third party may use securities pledged by any selling stockholder or borrowed from any selling stockholder or others to settle those sales or to close out any related open borrowings of stock or Private Placement Warrants, and may use securities received from any selling stockholder in settlement of those derivatives to close out any related open borrowings of stock or warrants. If treated as so under applicable securities laws, the third party in such sale transactions will be an underwriter and will be identified in the applicable prospectus supplement (or a post-effective amendment). In addition, any selling stockholder may otherwise loan or pledge shares of common stock or Private Placement Warrants to a financial institution or other third party that in turn may sell the securities short using this prospectus. Such financial institution or other third party may transfer its economic short position to investors in our securities or in connection with a concurrent offering of other securities.

In effecting sales, broker-dealers or agents engaged by the selling stockholders may arrange for other broker-dealers to participate. Broker-dealers or agents may receive commissions, discounts or concessions from the selling stockholders in amounts to be negotiated immediately prior to the sale.

In offering the shares of common stock or Private Placement Warrants covered by this prospectus, the selling stockholders and any broker-dealers who execute sales for them may be deemed to be "underwriters" within the meaning of the Securities Act in connection with such sales. Any profits realized by selling stockholders who are "underwriters," and the compensation of any broker-dealer who executes sales for them, may be deemed to be underwriting discounts and commissions.

In order to comply with the securities laws of certain states, if applicable, the common stock and Private Placement Warrants must be sold in such jurisdictions only through registered or licensed brokers or dealers. In addition, in certain states the shares of common stock and Private Placement Warrants may not be sold unless they

------

<u>[**Table of Contents**](#ib82e114cd19f45afae73e7a64e42f208_1390)</u>

have been registered or qualified for sale in the applicable state or an exemption from the registration or qualification requirement is available and is complied with.

We have advised the selling stockholders that the anti-manipulation rules of Regulation M under the Exchange Act may apply to sales of common stock or Private Placement Warrants in the market and to the activities of the selling and their affiliates. In addition, we will make copies of this prospectus available to the selling stockholders for the purpose of satisfying the prospectus delivery requirements of the Securities Act. The selling stockholders may indemnify any broker-dealer that participates in transactions involving the sale of the common stock or warrants against certain liabilities, including liabilities arising under the Securities Act.

At the time a particular offer of shares of common stock or Private Placement Warrants is made, if required, a prospectus supplement will be distributed that will set forth the number of securities being offered and the terms of the offering, including the name of any underwriter, dealer or agent, the purchase price paid by any underwriter, any discount, commission and other item constituting compensation, any discount, commission or concession allowed or reallowed or paid to any dealer, and the proposed selling price to the public.

We have agreed to indemnify certain of the selling stockholders against certain liabilities, including liabilities under the Securities Act and state securities laws, relating to the registration of the shares of common stock offered by this prospectus.

The validity of the securities offered by this prospectus will be passed upon by Covington & Burling LLP.

**EXPERTS**

The financial statements of AMCI Acquisition Corp. II as of December 31, 2021 and for the period from January 28, 2021 (inception) through December 31, 2021 appearing in this prospectus have been audited by Marcum LLP, independent registered public accounting firm, as set forth in their report thereon (which contains an explanatory paragraph relating to substantial doubt about the ability of AMCI Acquisition Corp. II to continue as a going concern as described in Note 1 to the financial statements), appearing elsewhere in this prospectus, and are included in reliance on such report given on the authority of such firm as experts in auditing and accounting.

The financial statements of LanzaTech NZ, Inc. as of December 31, 2021 and 2020 and for the years then ended included in this prospectus have been audited by Deloitte & Touche LLP, an independent registered public accounting firm, as stated in their report. Such financial statements are included in reliance on the report of such firm given their authority as experts in auditing and accounting.

**CHANGE IN THE REGISTRANT'S CERTIFYING ACCOUNTANT** 

On February 8, 2023, the Board approved a resolution appointing Deloitte as LanzaTech's independent registered public accounting firm to audit LanzaTech's consolidated financial statements for the fiscal year ending December 31, 2023. Deloitte serves as the independent registered public accounting firm of Legacy LanzaTech through the issuance of its December 31, 2022 financial statements. Accordingly, Marcum, AMCI's independent registered public accounting firm prior to the Business Combination, was informed on February 8, 2023 that it was dismissed as LanzaTech's independent registered public accounting firm, effective upon completion of Marcum's audit of AMCI's consolidated financial statements as of and for the year ended December 31, 2022, and the issuance of their report thereon.

The report of Marcum on AMCI's financial statements as of and for the most recent fiscal year ended December 31, 2021 did not contain an adverse opinion or a disclaimer of opinion, and were not qualified or modified as to uncertainties, audit scope or accounting principles, except as follows: Marcum's report on AMCI's financial statements as of and for the fiscal year ended December 31, 2021 contained a separate paragraph expressing substantial doubt about the AMCI's ability to continue as a going concern.

During AMCI's fiscal year ended December 31, 2021 and the subsequent interim period through September 30, 2022, there were no disagreements between AMCI and Marcum on any matter of accounting principles or practices, financial disclosure or auditing scope or procedure, which disagreements, if not resolved to the satisfaction of Marcum, would have caused it to make reference to the subject matter of the disagreements in its reports on AMCI's financial statements for such year.

During AMCI's fiscal year ended December 31, 2021 and the subsequent interim period through September 30, 2022, there were no "reportable events" (as defined in Item 304(a)(1)(v) of Regulation S-K ("Regulation S-K") under the Exchange Act, except that Marcum advised AMCI of the following material weaknesses related to: (i) the accounting for certain complex financial instruments and (ii) the accounting of certain fees related to financial advisory and placement agent services.

LanzaTech provided Marcum with a copy of the foregoing disclosures and has requested that Marcum furnish LanzaTech with a letter addressed to the SEC stating whether it agrees with the statements made by LanzaTech set forth above. A copy of Marcum's letter, dated February 13, 2023, is filed as Exhibit 16.1 to the registration statement of which this prospectus forms a part.

During the fiscal year ended December 31, 2021 and the subsequent interim period through September 30, 2022, neither LanzaTech, nor any party on behalf of LanzaTech, consulted with Deloitte with respect to either (i) the application of accounting principles to a specified transaction, either completed or proposed, or the type of the audit opinion that might be rendered with respect to LanzaTech's consolidated financial statements, and no written report

or oral advice was provided to LanzaTech by Deloitte that was an important factor considered by LanzaTech in reaching a decision as to any accounting, auditing or financial reporting issue, or (ii) any matter that was subject to any disagreement (as that term is defined in Item 304(a)(1)(iv) of Regulation S-K and the related instructions) or a reportable event (as that term is defined in Item 304(a)(1)(v) of Regulation S-K).

(1)This number includes up to 562,500 shares subject to forfeiture if the over-allotment option is not exercised in full or in part by the underwriters (see Note 5). On May 14, 2021, the Sponsor forfeited 718,750 shares of Class B common stock, resulting in the sponsor continuing to hold 4,312,500 shares of Class B common stock. All share and per-share amounts have been retroactively restated to reflect the share surrender.

**NOTES TO UNAUDITED CONDENSED FINANCIAL STATEMENTS**

**Note 1 — Description of Organization and Business Operations**

AMCI Acquisition Corp. II (the "Company") is a blank check company incorporated as a Delaware corporation on January 28, 2021. The Company was formed for the purpose of effecting a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or similar business combination with one or more businesses (the "business combination").

As of September 30, 2022, the Company has neither engaged in any operations nor generated any revenues. All activity to date relates to the Company's formation and the initial public offering (as defined below), described below and since the initial public offering, its search for a business combination target. The Company will not generate any operating revenues until after the completion of its initial business combination, at the earliest. The Company will generate non-operating income in the form of interest income on cash and cash equivalents from the proceeds derived from the initial public offering and from changes in the fair value of its derivative warrant liabilities, if applicable. The Company has selected December 31 as its fiscal year end.

The Company's sponsor is AMCI Sponsor II LLC, a Delaware limited liability company (the "Sponsor").

The registration statement for the Company's initial public offering was declared effective on August 3, 2021 (the "effective date"). On August 6, 2021, the Company consummated its initial public offering (the "initial public offering") of 15,000,000 units (the "units"). Each unit consists of one Class A common stock of the Company, par value $0.0001 per share (the "Class A common stock"), and one-half of one redeemable warrant of the Company (the "warrant"), each whole warrant entitling the holder thereof to purchase one Class A common stock for $11.50 per share. The units were sold at a price of $10.00 per unit, generating gross proceeds to the Company of $150,000,000 which is discussed in Note 3.

Simultaneously with the closing of the initial public offering, the Company completed the private sale of an aggregate of 3,500,000 warrants (the "private placement warrants") to the Sponsor at a purchase price of $1.00 per private placement warrant, generating gross proceeds to the Company of $3,500,000. The private placement warrants are identical to the warrants sold in the initial public offering, except that the private placement warrants, so long as they are held by the Sponsor or its permitted transferees, (i) are not redeemable by the Company, (ii) may not (including the Class A common stock issuable upon exercise of such private placement warrants), subject to certain limited exceptions, be transferred, assigned or sold by such holders until 30 days after the completion of the Company's initial business combination, (iii) may be exercised by the holders on a cashless basis and (iv) will be entitled to registration rights. No underwriting discounts or commissions were paid with respect to such sales.

As the initial public offering includes two instruments, Class A common stock and warrants, and as the warrants are classified as a financial liability, it is necessary to allocate the gross proceeds between Class A common stock and warrants. The Company adopted the residual method to allocate the gross proceeds between Class A common stock and warrants based on their relative fair values. The gross proceeds were first allocated to the fair value of the warrants and the residual amount was allocated to the Class A common stock. The percentage derived from this allocation was used to allocate the deferred offering costs between Class A common stock and warrants. Issuance costs allocated to the warrants were expensed to the Company's unaudited condensed statements of operations.

Transaction costs of the initial public offering amounted to $13,782,542 and consisted of $1,500,000 of underwriting discount, $5,250,000 of deferred underwriting discount, $6,509,758 in fair value of Class B common stock issued to Anchor Investors, and $522,784 of other offering costs.

A total of $150,000,000 was placed in a U.S.-based trust account maintained by Continental Stock Transfer & Trust Company, acting as trustee (the "trust account").

The Company must complete one or more initial business combination having an aggregate fair market value of at least 80% of the value of the assets held in the trust account (excluding the amount of deferred underwriting discounts held in trust and taxes payable on the income earned on the trust account) at the time of the signing a definitive agreement in connection with the initial business combination. However, the Company will only complete a business combination if the post-transaction company owns or acquires 50% or more of the outstanding voting securities of the target or otherwise acquires a controlling interest in the target sufficient for it not to be required to

**NOTES TO UNAUDITED CONDENSED FINANCIAL STATEMENTS**

register as an investment company under the Investment Company Act of 1940, as amended (the "Investment Company Act"). There is no assurance that the Company will be able to complete a business combination successfully.

Upon the closing of the initial public offering, management has agreed that an amount equal to at least $10.00 per unit sold in the initial public offering, including the proceeds of the private placement warrants, will be held in a trust account, located in the United States with Continental Stock Transfer & Trust Company acting as trustee, and will invest only in U.S. government securities, within the meaning set forth in Section 2(a)(16) of the Investment Company Act, having a maturity of 185 days or less or in money market funds meeting certain conditions under Rule 2a-7 promulgated under the Investment Company Act which invest only in direct U.S. government treasury obligations. Except with respect to interest earned on the funds held in the trust account that may be released to the Company to pay taxes, if any, the proceeds from the initial public offering and the sale of the private placement warrants will not be released from the trust account until the earliest of (i) the completion of initial business combination, (ii) the redemption of the Company's public shares if the Company is unable to complete an initial business combination by August 6, 2023, subject to applicable law, or (iii) the redemption of the Company's public shares properly submitted in connection with a stockholder vote to amend its amended and restated certificate of incorporation to modify the substance or timing of the Company's obligation to redeem 100% of its public shares if the Company has not consummated an initial business combination by August 6, 2023 or with respect to any other material provisions relating to stockholders' rights or pre-initial business combination activity. The proceeds deposited in the trust account could become subject to the claims of the Company's creditors, if any, which could have priority over the claims of the Company's public stockholders.

The Company will provide its public stockholders with the opportunity to redeem all or a portion of their public shares upon the completion of the initial business combination either (i) in connection with a stockholder meeting called to approve the business combination or (ii) without a stockholder vote by means of a tender offer. The decision as to whether the Company will seek stockholder approval of a proposed business combination or conduct a tender offer will be made by the Company, solely in its discretion. The stockholders will be entitled to redeem all or a portion of their public shares upon the completion of the initial business combination at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the trust account calculated as of two business days prior to the consummation of the initial business combination, including interest earned on the funds held in the trust account (which interest shall be net of taxes payable), divided by the number of then outstanding public shares, subject to the limitations and on the conditions described herein. The amount in the trust account is initially anticipated to be $10.00 per public share. The per share amount the Company will distribute to investors who properly redeem their shares will not be reduced by the deferred underwriting commissions the Company will pay to the representative of the underwriters.

The shares of common stock subject to redemption were recorded at a redemption value and classified as temporary equity upon the completion of the initial public offering, in accordance with Financial Accounting Standards Board's ("FASB") Accounting Standards Codification ("ASC") Topic 480, "Distinguishing Liabilities from Equity." In such case, the Company will proceed with a business combination if the Company has net tangible assets of at least $5,000,001 upon such consummation of a business combination and, if the Company seeks stockholder approval, a majority of the issued and outstanding shares voted are voted in favor of the business combination.

The Company will have only 24 months from the closing of the initial public offering to complete the initial business combination (the "Combination Period"). However, if the Company is unable to complete the initial business combination within the Combination Period, the Company will (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but not more than ten business days thereafter, redeem the public shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the trust account, including interest earned on the funds held in the trust account (which interest shall be net of taxes payable and up to $100,000 of interest to pay dissolution expenses), divided by the number of then outstanding public shares, which redemption will completely extinguish public stockholders' rights as stockholders (including the right to receive further liquidation distributions, if any), and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the Company's remaining stockholders and the Company's board of

**NOTES TO UNAUDITED CONDENSED FINANCIAL STATEMENTS**

directors, liquidate and dissolve, subject, in each case, to the Company's obligations under Delaware law to provide for claims of creditors and the requirements of other applicable law.

The Sponsor, officers and directors have agreed to (i) waive their redemption rights with respect to any founder shares and public shares they hold in connection with the completion of the initial business combination, (ii) waive their redemption rights with respect to any founder shares and public shares they hold in connection with a stockholder vote to approve an amendment to the Company's amended and restated certificate of incorporation, (iii) waive their rights to liquidating distributions from the trust account with respect to any founder shares they hold if the Company fails to complete the initial business combination within the Combination Period, and (iv) vote their founder shares and any public shares purchased during or after the initial public offering in favor of the initial business combination.

The Sponsor has agreed that it will be liable to the Company if and to the extent any claims by a third party for services rendered or products sold to the Company, or a prospective target business with which the Company has entered into a written letter of intent, confidentiality or other similar agreement or business combination agreement, reduce the amount of funds in the trust account to below the lesser of (i) $10.00 per public share and (ii) the actual amount per public share held in the trust account as of the date of the liquidation of the trust account, if less than $10.00 per share due to reductions in the value of the trust assets, less taxes payable, provided that such liability will not apply to any claims by a third party (other than the Company's independent registered public accounting firm) or prospective target business who executed a waiver of any and all rights to the monies held in the trust account (whether or not such waiver is enforceable), nor will it apply to any claims under the Company's indemnity of the underwriters of the initial public offering against certain liabilities, including liabilities under the Securities Act of 1933, as amended (the "Securities Act"). However, the Company has not asked the Sponsor to reserve for such indemnification obligations, nor has the Company independently verified whether the Sponsor has sufficient funds to satisfy its indemnity obligations and the Company believes that the Sponsor's only assets are securities of the Company. Therefore, the Company cannot assure that the Sponsor would be able to satisfy those obligations. None of the Company's officers or directors will indemnify the Company for claims by third parties including, without limitation, claims by vendors and prospective target businesses.

***Emerging Growth Company Status***

The Company is an "emerging growth company," as defined in Section 2(a) of the Securities Act, as modified by the Jumpstart Our Business Startups Act of 2012 (the "JOBS Act"), and it may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies including, but not limited to, not being required to comply with the independent registered public accounting firm attestation requirements of Section 404 of the Sarbanes-Oxley Act of 2002, reduced disclosure obligations regarding executive compensation in its periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved.

Further, Section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Securities and Exchange Act of 1934, as amended (the "Exchange Act")) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that an emerging growth company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such election to opt out is irrevocable. The Company has elected not to opt out of such extended transition period, which means that when a standard is issued or revised and it has different application dates for public or private companies, the Company, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This may make comparison of the Company's unaudited condensed financial statements with those of another public company which is neither an emerging growth company nor an emerging growth company which has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting standards used.

***Risks and Uncertainties***

Management is continuing to evaluate the impact of the COVID-19 pandemic on the industry and has concluded that while it is reasonably possible that the virus could have a negative effect on the Company's financial position, results of its operations and/or search for a target company, the specific impact is not readily determinable as of the date of these unaudited condensed financial statements. The unaudited condensed financial statements do not include any adjustments that might result from the outcome of this uncertainty.

On August 16, 2022, President Biden signed into law the Inflation Reduction Act of 2022 (the "IR Act"), which, among other things, imposes a new 1% U.S. federal excise tax on certain repurchases of stock by "covered corporations" (which include publicly traded domestic (i.e., U.S.) corporations) beginning in 2023, with certain exceptions (the "Excise Tax"). The Excise Tax is imposed on the repurchasing corporation itself, not its stockholders from which the stock is repurchased. Because we are a Delaware corporation and our securities are trading on Nasdaq, we are a "covered corporation" for this purpose. The amount of the Excise Tax is generally 1% of the fair market value of the shares repurchased at the time of the repurchase. However, for purposes of calculating the Excise Tax, repurchasing corporations are permitted to net the fair market value of certain new stock issuances against the fair market value of stock repurchases during the same taxable year. In addition, certain exceptions apply to the Excise Tax. The U.S. Department of the Treasury has authority to provide regulations and other guidance to carry out, and prevent the abuse or avoidance of the Excise Tax; however, no guidance has been issued to date. It is uncertain whether, and/or to what extent, the Excise Tax could apply to any repurchase by us of our common stock or in the event of our liquidation, in each instance after December 31, 2022, including any redemptions in connection with an initial business combination or in the event we do not consummate an initial business combination by August 6, 2023.

***Proposed Business Combination***

On March 8, 2022, the Company entered into an agreement and plan of merger (the "Merger Agreement") with AMCI Merger Sub, Inc., a Delaware corporation and a wholly owned subsidiary of the Company ("Merger Sub"), and LanzaTech NZ, Inc., a Delaware corporation ("LanzaTech"). The transactions contemplated by the Merger Agreement are referred to herein as the "Proposed Business Combination." The time of the closing of the Proposed Business Combination is referred to herein as the "Closing."

If the Proposed Business Combination is approved by the Company's stockholders and LanzaTech's stockholders, and the closing conditions in the Merger Agreement are satisfied or waived, then, among other things, upon the terms and subject to the conditions of the Merger Agreement and in accordance with Delaware General Corporation Law, Merger Sub will merge with and into LanzaTech, with LanzaTech surviving the Merger as the Company's wholly owned subsidiary (the "Merger"). In connection with the consummation of the Merger, the Company will be renamed "LanzaTech Global, Inc." and is referred to herein as "New LanzaTech" as of the time following such change of name.

Under the Merger Agreement, the Company has agreed to acquire all of the outstanding equity interests of LanzaTech for consideration consisting of equity interests of New LanzaTech valued at $1,817,000,000 in the aggregate. The consideration to be paid to holders of shares of LanzaTech capital stock will be shares of common stock of New LanzaTech ("New LanzaTech Common Stock"), valued at $10.00 per share, to be paid at the closing of the Merger. The number of shares of New LanzaTech Common Stock payable in the Merger in respect of each share of LanzaTech capital stock (each, a "LanzaTech Share") will be determined based on the exchange ratio (the "Exchange Ratio"), and certain corresponding adjustments, in each case as set forth in the Merger Agreement.

Pursuant to the Merger Agreement, at Closing: (i) each warrant to purchase LanzaTech Shares (each, a "LanzaTech Warrant") that is outstanding and unexercised immediately prior to Closing and would automatically be exercised or exchanged in full in accordance with its terms by virtue of the occurrence of the Merger, will be so automatically exercised or exchanged in full for the applicable LanzaTech Shares, and each such LanzaTech Share will be treated as being issued and outstanding immediately prior to Closing and will be canceled and converted into the right to receive the applicable shares of New LanzaTech Common Stock; and (ii) each LanzaTech Warrant that is outstanding and unexercised immediately prior to the Closing and is not automatically exercised in full as

------

**AMCI ACQUISITION CORP. II**

**NOTES TO UNAUDITED CONDENSED FINANCIAL STATEMENTS**

described in clause (i) will be converted into a warrant to purchase shares of New LanzaTech Common Stock, in which case (a) the number of shares underlying such New LanzaTech warrant (each, a "New LanzaTech Warrant") will be determined by multiplying the number of LanzaTech Shares subject to such warrant immediately prior to Closing, by the Exchange Ratio and (b) the per share exercise price of such New LanzaTech Warrant will be determined by dividing the per share exercise price of such LanzaTech Warrant immediately prior to the Effective Time by the Exchange Ratio, except that in the case of certain warrants specified in the Merger Agreement, such exercise price will be $10.00.

Pursuant to the Merger Agreement, at Closing, each option to purchase LanzaTech Shares (each, a "LanzaTech Option") will be converted into an option to purchase a number of shares of New LanzaTech Common Stock (rounded down to the nearest whole share) equal to the product of (i) the number of LanzaTech Shares subject to such LanzaTech Option multiplied by (ii) the Exchange Ratio. The exercise price of such New LanzaTech option will be equal to the quotient of (a) the exercise price per share of such LanzaTech Option in effect immediately prior to the Effective Time divided by (b) the Exchange Ratio (and as so determined, this exercise price will be rounded up to the nearest full cent).

Pursuant to the Merger Agreement, at Closing, each award of restricted shares of LanzaTech common stock (each, a "LanzaTech RSA") that is outstanding immediately prior to the Effective Time will be converted into an award of restricted shares of New LanzaTech Common Stock (each, a "New LanzaTech RSA") on the same terms and conditions as were applicable to such LanzaTech RSA immediately prior to the Effective Time, except that such New LanzaTech RSA will relate to a number of shares of New LanzaTech Common Stock equal to the number of LanzaTech Shares subject to such LanzaTech RSA, multiplied by the Exchange Ratio.

The closing of the Merger is subject to certain customary conditions, including, among others, (i) adoption by AMCI's stockholders and LanzaTech's stockholders of the Merger Agreement and their approval of certain other actions related to the Proposed Business Combination, (ii) the expiration or termination of the waiting period (or any extension thereof) applicable to the transactions contemplated by the Merger Agreement and any ancillary agreements, in each case under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, (iii) the effectiveness of a registration statement on Form S-4 (the "Registration Statement") under the Securities Act with respect to the shares of New LanzaTech Common Stock to be paid as consideration in the Merger, (iv) there being no government order or law enjoining, prohibiting or making illegal the consummation of the Merger or the transactions contemplated by the Merger Agreement, (v) AMCI having at least $5,000,001 of net tangible assets (as determined in accordance with Rule 3a51-1(g)(1) under the Exchange Act) after giving effect to any payments required to be made in connection with the redemption of AMCI's public shares and the proceeds from the Subscription Agreements described below, (vi) AMCI having at least $230,000,000 of cash at the closing of the Merger, consisting of cash held in AMCI's trust account after taking into account any redemption of AMCI's public shares, and the proceeds from the Subscription Agreements described below, net of transaction expenses of AMCI and LanzaTech, and (vii) the listing on Nasdaq of the shares of New LanzaTech Common Stock issued in connection with the Proposed Business Combination.

***Liquidity and Going Concern***

As of September 30, 2022, the Company had approximately $7,000 in its operating bank account and a working capital deficit of approximately $3.5 million , not taking into account tax obligations of approximately $536,000 that may be paid from income from investments held in the trust account.

The Company's liquidity needs up to September 30, 2022 have been satisfied through a contribution of $25,000 from the Sponsor to cover for certain offering costs in exchange for the issuance of Founder Shares, and a loan and advances from the Sponsor pursuant to the Note (as defined in Note 4). Subsequent to the initial public offering, net proceeds from the private placement of $0.9 million were placed in the operating account for working capital purposes. In addition, in order to finance transaction costs in connection with a business combination, the Sponsor or an affiliate of the Sponsor, or certain of the Company's officers and directors may, but are not obligated to, provide the Company Working Capital Loans (as defined in Note 4). On March 28, 2022, the Company entered into a noninterest-bearing Working Capital Loan with its Sponsor for the principal amount of up to $1.5 million. As of September 30, 2022 and December 31, 2021, there were no amounts outstanding under any Working Capital Loan.

**AMCI ACQUISITION CORP. II**

**NOTES TO UNAUDITED CONDENSED FINANCIAL STATEMENTS**

In connection with the Company's assessment of going concern considerations in accordance with FASB Accounting Standards Update ("ASU") 2014-15, "Disclosures of Uncertainties about an Entity's Ability to Continue as a Going Concern," management has determined that the liquidity condition, and the mandatory liquidation and subsequent dissolution that will be required if the Company does not complete a business combination before August 6, 2023 raises substantial doubt about the Company's ability to continue as a going concern. Although Management expects that it will be able to raise additional capital to support its planned activities and complete a business combination on or prior to August 6, 2023, it is uncertain whether it will be able to do so. No adjustments have been made to the carrying amounts of assets or liabilities should we be required to liquidate after August 6, 2023. The condensed financial statements do not include any adjustment that might be necessary if the Company is unable to continue as a going concern. The Company intends to complete a business combination before the mandatory liquidation date. Over this time period, the Company will be using the funds outside of the trust account for paying existing accounts payable, identifying and evaluating prospective initial business combination candidates, performing due diligence on prospective target businesses, paying for travel expenditures, selecting the target business to merge with or acquire, and structuring, negotiating and consummating the business combination.

**Note 2 — Basis of Presentation and Summary of Significant Accounting Policies**

***Basis of Presentation***

The accompanying unaudited condensed financial statements of the Company have been prepared in accordance with United States generally accepted accounting principles ("U.S. GAAP") for interim financial information and Article 8 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP. In the opinion of management, all adjustments (consisting of normal accruals) considered for a fair presentation have been included. Operating results for the three and nine months ended September 30, 2022 are not necessarily indicative of the results that may be expected for the year ending December 31, 2022 or any future period.

The accompanying unaudited condensed financial statements should be read in conjunction with the audited financial statements and notes thereto included in the Annual Report on Form 10-K filed by the Company with the U.S. Securities and Exchange Commission (the "SEC") on March 25, 2022.

***Concentration of Credit Risk***

Financial instruments that potentially subject the Company to concentrations of credit risk consist of cash accounts in a financial institution, which, at times, may exceed the Federal Deposit Insurance Corporation coverage limit of $250,000. As of September 30, 2022 and December 31, 2021, the Company has not experienced losses on these accounts and management believes the Company is not exposed to significant risks on such accounts.

***Cash and Cash Equivalents***

The Company considers all short-term investments with an original maturity of three months or less when purchased to be cash equivalents. The Company had no cash equivalents as of September 30, 2022 and December 31, 2021.

***Use of Estimates***

The preparation of unaudited condensed financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the unaudited condensed financial statements and the reported amounts of income and expenses during the reporting period. Making estimates requires management to exercise significant judgment. It is at least reasonably possible that the estimate of the effect of a condition, situation or set of circumstances that existed at the date of the unaudited condensed financial statements, which management considered in formulating its estimate, could change in the near term due to one or more future confirming events. Accordingly, the actual results could differ significantly from those estimates.

***Investments Held in the Trust Account***

The Company's portfolio of investments is comprised of U.S. government securities, within the meaning set forth in Section 2(a)(16) of the Investment Company Act, with a maturity of 185 days or less, or investments in money market funds that invest in U.S. government securities and generally have a readily determinable fair value, or a combination thereof. When the Company's investments held in the trust account are comprised of U.S. government securities, the investments are classified as trading securities. When the Company's investments held in the trust account are comprised of money market funds, the investments are recognized at fair value. Trading securities and investments in money market funds are presented on the condensed balance sheets at fair value at the end of each reporting period. Gains and losses resulting from the change in fair value of these securities is included in income on investments held in the trust account in the accompanying unaudited condensed statements of operations. The estimated fair values of investments held in the trust account are determined using available market information.

***Financial Instruments***

The fair value of the Company's assets and liabilities which qualify as financial instruments under the FASB ASC 820, "Fair Value Measurement," equal or approximate the carrying amounts represented in the condensed balance sheets.

***Fair Value Measurements***

Fair value is defined as the price that would be received for sale of an asset or paid for transfer of a liability, in an orderly transaction between market participants at the measurement date. GAAP establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). These tiers consist of:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Level 1, defined as observable inputs such as quoted prices (unadjusted) for identical instruments in active markets; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable such as quoted prices for similar instruments in active markets or quoted prices for identical or similar instruments in markets that are not active; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions, such as valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable.

In some circumstances, the inputs used to measure fair value might be categorized within different levels of the fair value hierarchy. In those instances, the fair value measurement is categorized in its entirety in the fair value hierarchy based on the lowest level input that is significant to the fair value measurement.

***Offering Costs Associated With Initial Public Offering***

Offering costs consisted of legal, accounting, underwriting fees and other costs incurred through the initial public offering that were directly related to the initial public offering. Offering costs were allocated to the separable financial instruments issued in the initial public offering based on a relative fair value basis, compared to total proceeds received. Offering costs associated with derivative warrant liabilities were expensed as incurred and presented as non-operating expenses in the unaudited condensed statements of operations. Offering costs associated with the Class A common stock issued were charged against the carrying value of the shares of Class A common stock upon the completion of the initial public offering. The Company classifies deferred underwriting commissions as non-current liabilities as their liquidation is not reasonably expected to require the use of current assets or require the creation of current liabilities.

**NOTES TO UNAUDITED CONDENSED FINANCIAL STATEMENTS**

***Class A Common Stock Shares Subject to Possible Redemption***

The Company accounts for its Class A common stock subject to possible redemption in accordance with the guidance in ASC Topic 480, "Distinguishing Liabilities from Equity." Class A common stock subject to mandatory redemption (if any) is classified as liability instruments and are measured at fair value. Conditionally redeemable Class A common stock (including Class A common stock that features redemption rights that are either within the control of the holder or subject to redemption upon the occurrence of uncertain events not solely within the Company's control) is classified as temporary equity. At all other times, Class A common stock is classified as stockholders' equity. The Company's Class A common stock feature certain redemption rights that are considered to be outside of the Company's control and subject to the occurrence of uncertain future events. Accordingly, as of the initial public offering, 15,000,000 shares of Class A common stock subject to possible redemption are presented at redemption value as temporary equity, outside of the stockholders' equity (deficit) section of the Company's condensed balance sheets.

Under ASC 480-10-S99, the Company has elected to recognize changes in the redemption value immediately as they occur and adjust the carrying value of the security to equal the redemption value at the end of the reporting period. This method would view the end of the reporting period as if it were also the redemption date of the security. Effective with the closing of the initial public offering, the Company recognized the accretion from initial book value to redemption amount, which resulted in charges against additional paid-in capital (to the extent available) and accumulated deficit.

***Derivative Financial Instruments***

The Company does not use derivative instruments to hedge exposures to cash flow, market, or foreign currency risks. The Company evaluates all of its financial instruments, including issued stock purchase warrants, to determine if such instruments are derivatives or contain features that qualify as embedded derivatives, pursuant to ASC 480 and FASB ASC Topic 815, "Derivatives and Hedging" ("ASC 815"). The classification of derivative instruments, including whether such instruments should be recorded as liabilities or as equity, is re-assessed at the end of each reporting period.

The public warrants and the private placement warrants are recognized as derivative liabilities in accordance with ASC 815. Accordingly, the Company recognizes the warrant instruments as liabilities at fair value and adjusts the carrying value of the instruments to fair value at each reporting period until they are exercised. The initial fair value of the public warrants issued in connection with the initial public offering was estimated using a Monte-Carlo simulation model. The fair value of the public warrants as of September 30, 2022 and as of December 31, 2021 is based on observable listed prices for such warrants. The fair value of the private placement warrants as of September 30, 2022 and as of December 31, 2021 is determined using a Black-Scholes option pricing model. The determination of the fair value of the warrant liability may be subject to change as more current information becomes available and, accordingly, the actual results could differ significantly. Derivative warrant liabilities are classified as non-current liabilities as their liquidation is not reasonably expected to require the use of current assets or require the creation of current liabilities.

***Income Taxes***

The Company follows the asset and liability method of accounting for income taxes under FASB ASC Topic 740, "Income Taxes" ("ASC 740"). Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that included the enactment date. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount expected to be realized.

ASC 740 prescribes a recognition threshold and a measurement attribute for the financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more likely than not to be sustained upon examination by taxing authorities. ASC 740 also

------

**AMCI ACQUISITION CORP. II**

**NOTES TO UNAUDITED CONDENSED FINANCIAL STATEMENTS**

provides guidance on derecognition, classification, interest and penalties, accounting in period, disclosure and transition. The Company recognizes accrued interest and penalties related to unrecognized tax benefits as income tax expense. The Company is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its position. The Company is subject to income tax examinations by major taxing authorities since inception. The Company's effective tax rate was 0.88% and 0.91% for the three and nine months ended September 30, 2022, respectively, and 0.00% for the three months ended September 30, 2021 and the period from January 28, 2021 (inception) through September 30, 2021. The effective tax rate differs from the statutory tax rate of 21% for the three and nine months ended September 30, 2022, the three months ended September 30, 2021 and the period from January 28, 2021 (inception) through September 30, 2021 due primarily to changes in fair value of derivative warrant liabilities, non-taxable gains on the settlement of deferred underwriting commissions, and the valuation allowance on the deferred tax assets.

***Net Income (Loss) Per Share Of Common Stock***

The Company complies with accounting and disclosure requirements of FASB ASC Topic 260, "Earnings Per Share." The Company has two classes of shares, which are referred to as Class A common stock and Class B common stock. Income and losses are shared pro rata between the two classes of shares. Net income (loss) per common share is calculated by dividing the net income (loss) by the weighted average shares of common stock outstanding for the respective period.

The calculation of diluted net income (loss) does not consider the effect of the warrants underlying the units sold in the initial public offering and the private placement warrants to purchase an aggregate of 11,000,000 shares of Class A common stock in the calculation of diluted income (loss) per share, because their exercise is contingent upon future events and their inclusion would be anti-dilutive under the treasury stock method. As a result, diluted net income (loss) per share is the same as basic net income (loss) per share for the three and nine months ended September 30, 2022 and for the three months ended September 30, 2021 and for the period from January 28, 2021 (inception) through September 30, 2021. Accretion associated with the redeemable Class A common stock is excluded from earnings per share as the redemption value approximates fair value.

The following table reflects presents a reconciliation of the numerator and denominator used to compute basic and diluted net income (loss) per share for each class of common stock:

***Recent Accounting Pronouncements***

In June 2022, the FASB issued ASU 2022-03, ASC Subtopic 820 "Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions". The ASU amends ASC 820 to clarify that a contractual sales restriction is not considered in measuring an equity security at fair value and to introduce new disclosure requirements for equity securities subject to contractual sale restrictions that are measured at fair value. The ASU applies to both holders and issuers of equity and equity-linked securities measured at fair value. The amendments in this ASU are effective for the Company in fiscal years beginning after December 15, 2023, and interim periods within those fiscal years. Early adoption is permitted for both interim and annual financial statements that have not yet been issued or made available for issuance. The Company is still evaluating the impact of this pronouncement on the condensed financial statements.

The Company's management does not believe that any other recently issued, but not yet effective, accounting standards updates, if currently adopted, would have a material effect on the Company's unaudited condensed financial statements.

**Note 3 — Initial Public Offering**

On August 6, 2021, the Company consummated its initial public offering of 15,000,000 units, at an offering price of $10.00 per unit, generating gross proceeds of $150.0 million, and incurring offering costs of approximately $13.8 million, inclusive of $1.5 million of underwriting discount, approximately $5.3 million in deferred underwriting commissions, approximately $6.5 million in fair value of Class B common stock issued to Anchor Investors, and approximately $0.5 million in other offering costs. Each whole warrant entitles the holder to purchase one share of Class A common stock at a price of $11.50 per share, subject to adjustment (see Note 8). Certain qualified institutional buyers or institutional accredited investors (the "Anchor Investors") purchased 15,480,000 units in the initial public offering. None of the Anchor Investors are affiliated with any member of the Company's management.

The underwriters had a 45-day option from the date of the underwriting agreement (August 3, 2021) to purchase up to an additional 2,250,000 units to cover over-allotments. On September 17, 2021, the over-allotment option expired unexercised, resulting in 562,500 shares of Class B common stock that were subject to forfeiture to be forfeited.

**Note 4 — Related Party Transactions**

***Founder Shares***

On January 29, 2021, the Sponsor paid $25,000, or approximately $0.005 per share, to cover certain offering costs in consideration for 5,031,250 shares of Class B common stock, par value $0.0001. In March 2021, the Sponsor transferred all of the founder shares it held to members of the Company's board of directors, management

**AMCI ACQUISITION CORP. II**

**NOTES TO UNAUDITED CONDENSED FINANCIAL STATEMENTS**

team, and persons or entities affiliated with AMCI Group (the "initial shareholders"). Such shares were fully paid. On May 14, 2021, the Sponsor surrendered 718,750 founder shares to the Company for no consideration, resulting in the Sponsor owning 4,312,500 founder shares. Up to 562,500 of the founder shares will be forfeited depending on the extent to which the underwriters' over-allotment is exercised. On September 17, 2021, the over-allotment option expired unexercised, resulting in 562,500 of the founder shares being forfeited.

In exchange for the Anchor Investors' participation in the initial public offering as described in Note 3, the Sponsor sold a total of 780,000 founder shares to the Anchor Investors. The Company determined that the fair value of these founder shares was approximately $6.5 million (or approximately $8.35 per share) using a Monte Carlo simulation. The Company recognized the excess fair value of these founder shares, over the price sold to the Anchor Investors, as an expense of the initial public offering resulting in a charge against the carrying value of Class A common stock subject to possible redemption.

The initial stockholders have agreed not to transfer, assign or sell any of their founder shares and any Class A common stocks issuable upon conversion thereof until the earlier to occur of: (A) one year after the completion of the initial business combination and (B) the date on which the Company completes a liquidation, merger, capital stock exchange or other similar transaction after the Company's initial business combination that results in all of the Company's stockholders having the right to exchange their Class A common stock for cash, securities or other property; except to certain permitted transferees and under certain circumstances (the "Lock-up"). Any permitted transferees will be subject to the same restrictions and other agreements of the company's initial stockholders with respect to any founder shares. Notwithstanding the foregoing, the founder shares will be released from the Lock-up if the closing price of the Company's Class A common stock equals or exceeds $12.00 per share (as adjusted for stock splits, stock capitalizations, reorganizations, recapitalizations and the like) for any 20 trading days within any 30-trading day period commencing at least 150 days after the company's initial business combination.

***Private Placement***

Simultaneously with the closing of the initial public offering, the Company's Sponsor has purchased an aggregate of 3,500,000 private placement warrants, each exercisable to purchase one Class A common stock at $11.50 per share, at a price of $1.00 per warrant, or $3,500,000 in the aggregate.

The private placement warrants will not be redeemable by the Company so long as they are held by the initial purchasers or their permitted transferees. The initial purchasers, or their permitted transferees, have the option to exercise the private placement warrants on a cashless basis. If the private placement warrants are held by holders other than initial purchasers or their permitted transferees, the private placement warrants will be redeemable by the Company and exercisable by the holders on the same basis as the warrants included in the units being sold in the initial public offering. Otherwise, the private placement warrants have terms and provisions that are identical to those of the warrants being sold as part of the units in the initial public offering.

If the private placement warrants are held by holders other than the Sponsor or its permitted transferees, the private placement warrants will be redeemable by the Company in all redemption scenarios and exercisable by the holders on the same basis as the warrants included in the units being sold in the initial public offering.

***Related Party Loans and Advances***

On January 29, 2021, the Sponsor agreed to loan the Company up to $300,000 to be used for a portion of the expenses of the initial public offering ("Note"). This loan was non-interest bearing, unsecured and payable upon the closing of the initial public offering. In addition to the Note, the Sponsor of the Company also paid certain administrative expenses and offering costs on behalf of the Company. These advances were due on demand and were non-interest bearing. The Company repaid the note payable and advances in exchange for the issuance of private placement warrants.

***Working Capital Loans***

In addition, in order to finance transaction costs in connection with an intended business combination, the Sponsor or an affiliate of the Sponsor, or certain of the Company's officers and directors may, but are not obligated

------

**AMCI ACQUISITION CORP. II**

**NOTES TO UNAUDITED CONDENSED FINANCIAL STATEMENTS**

to, loan the Company funds as may be required on a non-interest basis ("Working Capital Loans"). If the Company completes the initial business combination, it will repay the Working Capital Loans. In the event that the initial business combination does not close, the Company may use a portion of the working capital held outside the trust account to repay the Working Capital Loans but no proceeds from the trust account would be used to repay the Working Capital Loans. Up to $1,500,000 of such Working Capital Loans may be convertible into warrants of the post-business combination entity at a price of $1.00 per warrant at the option of the lender. Such warrants would be identical to the private placement warrants. Except as set forth above, the terms of Working Capital Loans, if any, have not been determined and no written agreements exist with respect to such loans. On March 28, 2022, the Company entered into a noninterest-bearing Working Capital Loan with its Sponsor for the principal amount of up to $1.5 million. As of September 30, 2022 and December 31, 2021, the Company had no borrowings under the Working Capital Loans.

***Administrative Service Fee***

Subsequent to the closing of the initial public offering, the Company will pay its Sponsor $10,000 per month for office space, secretarial and administrative services provided to members of the management team. Upon completion of the initial business combination or the Company's liquidation, the Company will cease paying these monthly fees. For the three months ended September 30, 2022 and 2021, the Company incurred $30,000 and $20,000, respectively, of such fees, included as general and administrative fees — related party on the accompanying unaudited condensed statements of operations. For the nine months ended September 30, 2022 and for the period from January 28, 2021 (inception) through September 30, 2021, the Company incurred $90,000 and $20,000, respectively, of such fees, included as general and administrative fees — related party on the accompanying unaudited condensed statements of operations. As of September 30, 2022 and December 31, 2021, approximately $90,000 and $50,000, respectively, of such fees were included in due to related party on the accompanying condensed balance sheets.

The Sponsor, officers and directors, or any of their respective affiliates will be reimbursed for any out-of-pocket expenses incurred in connection with activities on the Company's behalf such as identifying potential target businesses and performing due diligence on suitable business combinations. The Company's audit committee will review on a quarterly basis all payments that were made by the Company to the Sponsor, directors, officers or directors of the Company, or any of their affiliates. As of September 30, 2022 and December 31, 2021, there were approximately $596,000 and $0, respectively, of such fees included as due to related party on the accompanying condensed balance sheets.

**Note 5 — Commitments and Contingencies**

***Registration Rights***

The holders of the (i) founder shares, which were issued in a private placement prior to the closing of the initial public offering, (ii) private placement warrants, which were issued in a private placement simultaneously with the closing of the initial public offering and the shares of Class A common stock underlying such private placement warrants and (iii) private placement warrants that may be issued upon conversion of Working Capital Loans will have registration rights to require the Company to register a sale of any of its securities held by them prior to the consummation of the initial business combination pursuant to a registration rights agreement to be signed prior to or on the effective date of the initial public offering. The holders of these securities are entitled to make up to three demands, excluding short form demands, that the Company registers such securities. In addition, the holders have certain "piggy-back" registration rights with respect to registration statements filed subsequent to the Company's completion of its initial business combination. The Company will bear the expenses incurred in connection with the filing of any such registration statements. In addition, the Anchor Investors will, upon receipt of their founder shares, execute a registration rights agreement with respect to their founder shares.

***Underwriting Agreement***

The Company granted the underwriters a 45-day option from the date of the underwriting agreement to purchase up to an additional 2,250,000 units to cover over-allotments, if any. On September 17, 2021, the over-allotment option expired unexercised, resulting in the forfeiture of 562,500 shares of founder shares.

------

**AMCI ACQUISITION CORP. II**

**NOTES TO UNAUDITED CONDENSED FINANCIAL STATEMENTS**

The underwriters were paid an underwriting discount of one percent (1%) of the gross proceeds of the initial public offering, or $1,500,000. Additionally, in connection with the initial public offering, the Company agreed to pay the underwriters a deferred underwriting fee of 3.5% of the gross proceeds, or $5,250,000, of the initial public offering upon the completion of the Company's initial business combination. On September 29, 2022, as discussed further below, Evercore Group L.L.C., ("Evercore") the representative of the underwriters of the initial public offering, waived its deferred underwriting fee that accrued from its participation in the initial public offering. The Company recognized approximately $4.9 million of the commissions waiver as a reduction to additional paid-in capital in the condensed statements of changes in stockholders' deficit for the three and nine months ended September 30, 2022, as this portion represents an extinguishment of deferred underwriting commissions on public shares which was originally recognized in accumulated deficit. The remaining balance of approximately $172,000 is recognized as a gain from extinguishment of deferred underwriting commissions on public warrants in the condensed statements of operations, which represents the original amount expensed in the Company's initial public offering.

On September 27, 2022 and September 29, 2022, the Company received notice and a formal letter, respectively, from Evercore Group, L.L.C., an underwriter in the Company's initial public offering, advising that it had, among other things, (i) resigned from and ceased or refused to act in, its roles as co-placement agent, co-capital markets advisor and exclusive financial advisor to the Company in connection with the Merger and as underwriter in the Company's initial public offering and (ii) waived its right to receive an aggregate of $13,050,000 in fees, all of which were contingent upon and payable upon the closing of the Merger, consisting of $500,000 for its role as co-placement agent, $7,500,000 for its role as exclusive financial advisor and $5,050,000 of deferred underwriting fees accrued from its participation in the Company's initial public offering, as well as any expense reimbursements owed to it under those arrangements.

**Note 6 — Class A Common Stock Subject to Possible Redemption**

The Company's Class A common stock feature certain redemption rights that are considered to be outside of the Company's control and subject to the occurrence of future events. The Company is authorized to issue 280,000,000 shares of Class A common stock with a par value of $0.0001 per share. Holders of the Company's Class A common stock are entitled to one vote for each share. As of September 30, 2022 and December 31, 2021, there were 15,000,000 shares of Class A common stock outstanding subject to possible redemption and are classified outside of permanent equity in the condensed balance sheets.

applicable to the shares of each series. As of September 30, 2022 and December 31, 2021, there were no shares of preferred stock issued or outstanding.

**Class A Common Stock** — The Company is authorized to issue 280,000,000 shares of Class A common stock with a par value of $0.0001 per share. As of September 30, 2022 and December 31, 2021, there were 15,000,000 shares of Class A common stock issued and outstanding, all of which were subject to possible redemption and are classified as temporary equity (see Note 6).

**Class B Common Stock** — The Company is authorized to issue 20,000,000 Class B common stock with a par value of $0.0001 per share. As of September 30, 2022 and December 31, 2021, there were 3,750,000 shares of Class B common stock issued and outstanding (see Note 4).

Holders of Class A common stock and holders of Class B common stock will vote together as a single class on all matters submitted to a vote of the Company's stockholders except as required by law. Unless specified in the Company's amended and restated certificate of incorporation, or as required by applicable provisions of the Delaware General Corporation Law ("DGCL") or applicable stock exchange rules, the affirmative vote of a majority of the Company's shares of common stock that are voted is required to approve any such matter voted on by its stockholders.

The Class B common stock will automatically convert into shares of Class A common stock concurrently with or immediately following the consummation of the initial business combination on a one-for-one basis, subject to adjustment for stock splits, stock dividends, reorganizations, recapitalizations and the like, and subject to further adjustment as provided herein. In the case that additional shares of Class A common stock or equity-linked securities are issued or deemed issued in connection with the initial business combination, the number of shares of Class A common stock issuable upon conversion of all founder shares will equal, in the aggregate, on an as-converted basis, 20% of the total number of shares of Class A common stock outstanding after such conversion (after giving effect to any redemptions of shares of Class A common stock by public stockholders), including the total number of shares of Class A common stock issued, or deemed issued or issuable upon conversion or exercise of any equity-linked securities or rights issued or deemed issued, by the Company in connection with or in relation to the consummation of the initial business combination, excluding any shares of Class A common stock or equity-linked securities or rights exercisable for or convertible into shares of Class A common stock issued, or to be issued, to any seller in the initial business combination and any private placement warrants issued to the Sponsor, officers or directors upon conversion of working capital loans, provided that such conversion of founder shares will never occur on a less than one-for-one basis.

**Note 8 — Warrants**

As of September 30, 2022 and December 31, 2021, in connection with the initial public offering, the Company has 7,500,000 public warrants and 3,500,000 private placement warrants outstanding.

Each whole warrant entitles the registered holder to purchase one share of Class A common stock at a price of $11.50 per share, subject to adjustment as discussed below, at any time commencing 30 days after the completion of the initial business combination, provided that the Company has an effective registration statement under the Securities Act covering the shares of Class A common stock issuable upon exercise of the warrants and a current prospectus relating to them is available (or the Company permits holders to exercise their warrants on a cashless basis under the circumstances specified in the warrant agreement) and such shares are registered, qualified or exempt from registration under the securities, or blue sky, laws of the state of residence of the holder. The warrants will expire five years after the completion of the Company's initial business combination, at 5:00 p.m., New York City time, or earlier upon redemption or liquidation.

The Company has agreed that as soon as practicable, but in no event later than fifteen (15) business days after the closing of the initial business combination, it will use its best efforts to file with the SEC a registration statement for the registration, under the Securities Act, of the Class A common stock issuable upon exercise of the warrants. The Company will use its best efforts to cause the same to become effective and to maintain the effectiveness of such registration statement, and a current prospectus relating thereto, until the expiration of the warrants in accordance with the provisions of the warrant agreement. If a registration statement covering the shares of Class A

**NOTES TO UNAUDITED CONDENSED FINANCIAL STATEMENTS**

common stock issuable upon exercise of the warrants is not effective by the sixtieth (60th) business day after the closing of the initial business combination, warrant holders may, until such time as there is an effective registration statement and during any period when the Company will have failed to maintain an effective registration statement, exercise warrants on a "cashless basis" in accordance with Section 3(a)(9) of the Securities Act or another exemption. Notwithstanding the above, if the Company's Class A common stock are at the time of any exercise of a warrant not listed on a national securities exchange such that they satisfy the definition of a "covered security" under Section 18(b)(1) of the Securities Act, the Company may, at its option, require holders of public warrants who exercise their warrants to do so on a "cashless basis" in accordance with Section 3(a)(9) of the Securities Act and, in the event the Company so elect, it will not be required to file or maintain in effect a registration statement, and in the event the Company do not so elect, it will use its best efforts to register or qualify the shares under applicable blue sky laws to the extent an exemption is not available.

Redemption of warrants when the price per share of Class A common stock equals or exceeds $18.00.

Once the warrants become exercisable, the Company may redeem the outstanding warrants:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• in whole and not in part;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• at a price of $0.01 per warrant;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• upon a minimum of 30 days' prior written notice of redemption to each warrant holder; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• if, and only if, the closing price of the Class A common stock equals or exceeds $18.00 per share (as adjusted for adjustments to the number of shares issuable upon exercise or the exercise price of a warrant as described under the heading "— Warrants — Public Stockholders' Warrants — Anti-Dilution Adjustments") for any 20 trading days within a 30-trading day period ending three trading days before we send the notice of redemption to the warrant holders.

Redemption of warrants when the price per share of Class A common stock equals or exceeds $10.00.

Once the warrants become exercisable, the Company may redeem the outstanding warrants:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• in whole and not in part;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• at $0.10 per warrant upon a minimum of 30 days' prior written notice of redemption provided that holders will be able to exercise their warrants on a cashless basis prior to redemption and receive that number of shares determined by reference to the table below, based on the redemption date and the "fair market value" (as defined below) of our Class A common stock except as otherwise described below; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• if, and only if, the closing price of our Class A common stock equals or exceeds $10.00 per public share (as adjusted for adjustments to the number of shares issuable upon exercise or the exercise price of a warrant as described under the heading "— Warrants — Public Stockholders' Warrants — Anti-Dilution Adjustments") for any 20 trading days within the 30-trading day period ending three trading days before we send the notice of redemption to the warrant holders.

In addition, if (x) the Company issue additional shares of Class A common stock or equity-linked securities for capital raising purposes in connection with the closing of our initial business combination at an issue price or effective issue price of less than $9.20 per share (with such issue price or effective issue price to be determined in good faith by the Company's board of directors and, in the case of any such issuance to the Sponsor or its affiliates, without taking into account any founder shares held by the Sponsor or such affiliates, as applicable, prior to such issuance) (the "Newly Issued Price"), (y) the aggregate gross proceeds from such issuances represent more than 60% of the total equity proceeds, and interest thereon, available for the funding of our initial business combination on the date of the consummation of the initial business combination (net of redemptions), and (z) the volume weighted average trading price of the Company's Class A common stock during the 20 trading day period starting on the trading day prior to the day on which the Company consummate the initial business combination (such price, the "Market Value") is below $9.20 per share, the exercise price of the warrants will be adjusted (to the nearest cent) to be equal to 115% of the higher of the Market Value and the Newly Issued Price, the $18.00 per share redemption

Transfers to/from Levels 1, 2 and 3 are recognized at the beginning of the reporting period. The estimated fair value of public warrants was transferred from a Level 3 fair value measurement to a Level 1 measurement, when the public warrants were separately listed and traded in September 2021. There were no other transfers between levels in the nine months ended September 30, 2022 and in the period from January 28, 2021 (inception) through December 31, 2021.

Level 1 assets include investments in mutual funds invested in U.S. government securities and derivative warrant liabilities (public warrants). The Company uses inputs such as actual trade data, quoted market prices from dealers or brokers, and other similar sources to determine the fair value of its investments.

For periods where no observable traded price is available, the fair value of the public warrants has been estimated using a Monte-Carlo simulation model and the private placement warrants has been estimated using a Black-Scholes option pricing model. For periods subsequent to the detachment of the public warrants from the units, the fair value of the public warrants is based on the observable listed price for such warrants. The estimated fair value of the public and private placement warrants, prior to the public warrants being traded in an active market, was determined using Level 3 inputs. Inherent in a Monte-Carlo simulation and Black-Scholes option pricing model are assumptions related to the unit price, expected volatility, risk-free interest rate, term to expiration, and dividend yield. The unit price is based on the publicly traded price of the units as of the measurement date. The Company estimated the volatility for the public and private placement warrants based on the implied volatility from the traded prices of warrants issued by other special purpose acquisition companies. The risk-free interest rate is based on

------

**AMCI ACQUISITION CORP. II**

**NOTES TO UNAUDITED CONDENSED FINANCIAL STATEMENTS**

interpolated U.S. Treasury rates, commensurate with a similar term to the public and private placement warrants. The expected life of the warrants is assumed to be equivalent to their remaining contractual term. Finally, the Company does not anticipate paying a dividend. Any changes in these assumptions can change the valuation significantly.

For the three months ended September 30, 2022 and 2021, the Company recognized a change to the statement of operations resulting from a decrease (increase) in the fair value of liabilities of approximately $1.4 million and $1.4 million, respectively, presented as change in fair value of derivative warrant liabilities on the accompanying statements of operations. For the nine months ended September 30, 2022 and for the period from January 28, 2021 (inception) through September 30, 2021, the Company recognized a change to the statement of operations resulting from a decrease (increase) in the fair value of liabilities of approximately $4.1 million and $1.4 million, respectively, presented as change in fair value of derivative warrant liabilities on the accompanying statements of operations.

The following table provides quantitative information regarding Level 3 fair value measurements inputs at their measurement dates:

---

| | | |
|:---|:---|:---|
| | **As of September 30, 2022** | **As of December 31, 2021** |
| Exercise price | $11.50 | $11.50 |
| Volatility | 5.8% | 9.6% |
| Stock price | $9.79 | $9.66 |
| Remaining term (years) | 5.19 | 5.75 |
| Risk-free rate | 3.97% | 1.32% |

|:---|:---|
| Derivative warrant liabilities at December 31, 2021 | $1785000 |

**Note 10 — Subsequent Events**

On October 18, 2022, the Company entered into additional subscription agreements (the "Subscription Agreements") with certain accredited investors (collectively, the "Additional PIPE Investors"), pursuant to which, among other things, the Company agreed to issue and sell, in a private placement to close immediately prior to the closing of the Merger, an aggregate of 5,500,000 shares of Class A common stock at a purchase price of $10.00 per share to the Additional PIPE Investors.

The Company evaluated subsequent events and transactions that occurred up to the date the unaudited condensed financial statements were issued. Based upon this review and except in the case of the foregoing, the Company did not identify any subsequent events that would have required adjustment or disclosure in the unaudited condensed financial statements.

To the Shareholders and Board of Directors of

AMCI Acquisition Corp. II

**Opinion on the Financial Statements**

We have audited the accompanying balance sheet of AMCI Acquisition Corp. II (the "Company") as of December 31, 2021, the related statements of operations, changes in stockholders' deficit and cash flows for the period from January 28, 2021 (inception) through December 31, 2021, and the related notes (collectively referred to as the "financial statements"). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2021, and the results of its operations and its cash flows for the period from January 28, 2021 (inception) through December 31, 2021, in conformity with accounting principles generally accepted in the United States of America.

**Explanatory Paragraph – Going Concern**

The accompanying financial statements have been prepared assuming that the Company will continue as a going concern. As more fully described in Note 1 to the financial statements, the Company's business plan is dependent on the completion of a business combination and the Company's cash and working capital as of December 31, 2021 are not sufficient to complete its planned activities for a reasonable period of time, which is considered to be one year from the issuance date of the financial statements. These conditions raise substantial doubt about the Company's ability to continue as a going concern. Management's plans with regard to these matters are also described in Note 1. The financial statements do not include any adjustments that might result from the outcome of this uncertainty.

**Basis for Opinion**

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audit. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) ("PCAOB") and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audit, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control over financial reporting. Accordingly, we express no such opinion.

Our audit included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audit also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audit provides a reasonable basis for our opinion.

**AMCI ACQUISITION CORP. II**

**NOTES TO THE FINANCIAL STATEMENTS**

**For the period from January 28, 2021 (inception) through December 31, 2021**

**Note 1 — Description of Organization and Business Operations**

AMCI Acquisition Corp. II (the "Company") is a blank check company incorporated as a Delaware corporation on January 28, 2021. The Company was formed for the purpose of effecting a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or similar business combination with one or more businesses (the "business combination").

As of December 31, 2021, the Company has neither engaged in any operations nor generated any revenues. All activity for the period from January 28, 2021 (inception) through December 31, 2021 relates to the Company's formation and the initial public offering ("initial public offering"), described below. The Company will not generate any operating revenues until after the completion of its initial business combination, at the earliest. The Company will generate non-operating income in the form of interest income on cash and cash equivalents from the proceeds derived from the initial public offering and from changes in the fair value of its derivative warrant liabilities, if applicable. The Company has selected December 31 as its fiscal year end.

The Company's sponsor is AMCI Sponsor II LLC, a Delaware limited liability company (the "Sponsor").

The registration statement for the Company's initial public offering was declared effective on August 3, 2021 (the "effective date"). On August 6, 2021, the Company consummated its initial public offering of 15,000,000 units (the "units"). Each unit consists of one Class A common stock of the Company, par value $0.0001 per share (the "Class A common stock"), and one-half of one redeemable warrant of the Company (the "warrant"), each whole warrant entitling the holder thereof to purchase one Class A common stock for $11.50 per share. The units were sold at a price of $10.00 per unit, generating gross proceeds to the Company of $150,000,000, which is discussed in Note 3.

Simultaneously with the closing of the initial public offering, the Company completed the private sale of an aggregate of 3,500,000 warrants (the "private placement warrants") to the Sponsor at a purchase price of $1.00 per private placement warrant, generating gross proceeds to the Company of $3,500,000. The private placement warrants are identical to the warrants sold in the initial public offering, except that the private placement warrants, so long as they are held by the Sponsor or its permitted transferees, (i) are not redeemable by the Company, (ii) may not (including the Class A common stock issuable upon exercise of such private placement warrants), subject to certain limited exceptions, be transferred, assigned or sold by such holders until 30 days after the completion of the Company's initial business combination, (iii) may be exercised by the holders on a cashless basis and (iv) will be entitled to registration rights. No underwriting discounts or commissions were paid with respect to such sales.

As the initial public offering includes two instruments, Class A common stock and warrants, and as the warrants are classified as a financial liability, it is necessary to allocate the gross proceeds between Class A common stock and warrants. The Company adopted the residual method to allocate the gross proceeds between Class A common stock and warrants based on their relative fair values. The gross proceeds were first allocated to the fair value of the warrants and the residual amount was allocated to the Class A common stock. The percentage derived from this allocation was used to allocate the deferred offering costs between Class A common stock and warrants. Issuance costs allocated to the warrants were expensed to the Company's statement of operations.

Transaction costs of the initial public offering amounted to $13,782,542 and consisted of $1,500,000 of underwriting discount, $5,250,000 of deferred underwriting discount, $6,509,758 in fair value of Class B common stock issued to Anchor Investors, and $522,784 of other offering costs.

A total of $150,000,000 was placed in a U.S.-based trust account maintained by Continental Stock Transfer & Trust Company, acting as trustee.

The Company must complete one or more initial business combination having an aggregate fair market value of at least 80% of the value of the assets held in the trust account (excluding the amount of deferred underwriting discounts held in trust and taxes payable on the income earned on the trust account) at the time of the signing a definitive agreement in connection with the initial business combination. However, the Company will only complete a business combination if the post-transaction company owns or acquires 50% or more of the outstanding voting securities of the target or otherwise acquires a controlling interest in the target sufficient for it not to be required to

register as an investment company under the Investment Company Act of 1940, as amended (the "Investment Company Act"). There is no assurance that the Company will be able to complete a business combination successfully.

Upon the closing of the initial public offering, management has agreed that an amount equal to at least $10.00 per unit sold in the initial public offering, including the proceeds of the private placement warrants, will be held in a trust account (the "trust account"), located in the United States with Continental Stock Transfer & Trust Company acting as trustee, and will invest only in U.S. government securities, within the meaning set forth in Section 2(a)(16) of the Investment Company Act, having a maturity of 185 days or less or in money market funds meeting certain conditions under Rule 2a-7 promulgated under the Investment Company Act which invest only in direct U.S. government treasury obligations. Except with respect to interest earned on the funds held in the trust account that may be released to the Company to pay taxes, if any, the proceeds from the initial public offering and the sale of the private placement warrants will not be released from the trust account until the earliest of (i) the completion of initial business combination, (ii) the redemption of the Company's public shares if the Company is unable to complete an initial business combination by August 6, 2023, subject to applicable law, or (iii) the redemption of the Company's public shares properly submitted in connection with a stockholder vote to amend its amended and restated certificate of incorporation to modify the substance or timing of the Company's obligation to redeem 100% of its public shares if the Company has not consummated an initial business combination by August 6, 2023 or with respect to any other material provisions relating to stockholders' rights or pre-initial business combination activity. The proceeds deposited in the trust account could become subject to the claims of the Company's creditors, if any, which could have priority over the claims of the Company's public stockholders.

The Company will provide its public stockholders with the opportunity to redeem all or a portion of their public shares upon the completion of the initial business combination either (i) in connection with a stockholder meeting called to approve the business combination or (ii) without a stockholder vote by means of a tender offer. The decision as to whether the Company will seek stockholder approval of a proposed business combination or conduct a tender offer will be made by the Company, solely in its discretion. The stockholders will be entitled to redeem all or a portion of their public shares upon the completion of the initial business combination at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the trust account calculated as of two business days prior to the consummation of the initial business combination, including interest earned on the funds held in the trust account (which interest shall be net of taxes payable), divided by the number of then outstanding public shares, subject to the limitations and on the conditions described herein. The amount in the trust account is initially anticipated to be $10.00 per public share. The per share amount the Company will distribute to investors who properly redeem their shares will not be reduced by the deferred underwriting commissions the Company will pay to the representative of the underwriters.

The shares of common stock subject to redemption were recorded at a redemption value and classified as temporary equity upon the completion of the initial public offering, in accordance with Financial Accounting Standards Board's ("FASB") Accounting Standards Codification ("ASC") Topic 480, "Distinguishing Liabilities from Equity." In such case, the Company will proceed with a business combination if the Company has net tangible assets of at least $5,000,001 upon such consummation of a business combination and, if the Company seeks stockholder approval, a majority of the issued and outstanding shares voted are voted in favor of the business combination.

The Company will have only 24 months from the closing of the initial public offering to complete the initial business combination (the "Combination Period"). However, if the Company is unable to complete the initial business combination within the Combination Period, the Company will (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but not more than ten business days thereafter, redeem the public shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the trust account, including interest earned on the funds held in the trust account (which interest shall be net of taxes payable and up to $100,000 of interest to pay dissolution expenses), divided by the number of then outstanding public shares, which redemption will completely extinguish public stockholders' rights as stockholders (including the right to receive further liquidation distributions, if any), and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the Company's remaining stockholders and the Company's board of

directors, liquidate and dissolve, subject, in each case, to the Company's obligations under Delaware law to provide for claims of creditors and the requirements of other applicable law.

The Sponsor, officers and directors have agreed to (i) waive their redemption rights with respect to any founder shares and public shares they hold in connection with the completion of the initial business combination, (ii) waive their redemption rights with respect to any founder shares and public shares they hold in connection with a stockholder vote to approve an amendment to the Company's amended and restated certificate of incorporation, (iii) waive their rights to liquidating distributions from the trust account with respect to any founder shares they hold if the Company fails to complete the initial business combination within the Combination Period, and (iv) vote their founder shares and any public shares purchased during or after the initial public offering in favor of the initial business combination.

The Sponsor has agreed that it will be liable to the Company if and to the extent any claims by a third party for services rendered or products sold to the Company, or a prospective target business with which the Company has entered into a written letter of intent, confidentiality or other similar agreement or business combination agreement, reduce the amount of funds in the trust account to below the lesser of (i) $10.00 per public share and (ii) the actual amount per public share held in the trust account as of the date of the liquidation of the trust account, if less than $10.00 per share due to reductions in the value of the trust assets, less taxes payable, provided that such liability will not apply to any claims by a third party (other than the Company's independent registered public accounting firm) or prospective target business who executed a waiver of any and all rights to the monies held in the trust account (whether or not such waiver is enforceable), nor will it apply to any claims under the Company's indemnity of the underwriters of the initial public offering against certain liabilities, including liabilities under the Securities Act. However, the Company has not asked the Sponsor to reserve for such indemnification obligations, nor has the Company independently verified whether the Sponsor has sufficient funds to satisfy its indemnity obligations and the Company believes that the Sponsor's only assets are securities of the Company. Therefore, the Company cannot assure that the Sponsor would be able to satisfy those obligations. None of the Company's officers or directors will indemnify the Company for claims by third parties including, without limitation, claims by vendors and prospective target businesses.

***Emerging Growth Company Status***

The Company is an "emerging growth company," as defined in Section 2(a) of the Securities Act, as modified by the Jumpstart Our Business Startups Act of 2012 (the "JOBS Act"), and it may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies including, but not limited to, not being required to comply with the independent registered public accounting firm attestation requirements of Section 404 of the Sarbanes-Oxley Act of 2002, reduced disclosure obligations regarding executive compensation in its periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved.

Further, Section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that an emerging growth company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such election to opt out is irrevocable. The Company has elected not to opt out of such extended transition period, which means that when a standard is issued or revised and it has different application dates for public or private companies, the Company, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This may make comparison of the Company's financial statements with another public company which is neither an emerging growth company nor an emerging growth company which has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting standards used.

**NOTES TO THE FINANCIAL STATEMENTS**

**For the period from January 28, 2021 (inception) through December 31, 2021**

***Risks and Uncertainties***

Management is continuing to evaluate the impact of the COVID-19 pandemic on the industry and has concluded that while it is reasonably possible that the virus could have a negative effect on the Company's financial position, results of its operations and/or search for a target company, the specific impact is not readily determinable as of the date of these financial statements. The financial statements do not include any adjustments that might result from the outcome of this uncertainty.

***Proposed Business Combination***

As more fully described in Note 11, on March 8, 2022, the Company entered into an agreement and plan of merger (the "Merger Agreement") with AMCI Merger Sub, Inc., a Delaware corporation and a wholly owned subsidiary of the Company ("Merger Sub"), and LanzaTech NZ, Inc., a Delaware corporation ("LanzaTech"). Upon consummation of the transactions, the Company will change its name to "LanzaTech Global, Inc."

***Liquidity and Going Concern***

As of December 31, 2021, the Company had approximately $0.3 million in its operating bank account and a working capital deficit of approximately $0.1 million.

The Company's liquidity needs up to December 31, 2021 have been satisfied through a contribution of $25,000 from the Sponsor to cover for certain offering costs in exchange for the issuance of founder shares, and a loan and advances from the Sponsor pursuant to the Note (as defined in Note 4). Subsequent to the initial public offering, net proceeds from the private placement of $0.9 million were placed in the operating account for working capital purposes. In addition, in order to finance transaction costs in connection with a business combination, the Sponsor or an affiliate of the Sponsor, or certain of the Company's officers and directors may, but are not obligated to, provide the Company Working Capital Loans (as defined in Note 4). As of December 31, 2021, there were no amounts outstanding under any Working Capital Loan.

In connection with the Company's assessment of going concern considerations in accordance with Financial Accounting Standard Board's Accounting Standards Update ("ASU") 2014-15, "*Disclosures of Uncertainties about an Entity's Ability to Continue as a Going Concern*," management has determined that the Company would not be able to meet its obligations as they become due within one year after the date that the financial statements are available to be issued. As such, management has determined that the liquidity condition raises substantial doubt about the Company's ability to continue as a going concern. As of December 31, 2021, no adjustments have been made to the carrying amounts of assets or liabilities.

**Note 2 — Basis of Presentation and Summary of Significant Accounting Policies**

***Basis of Presentation***

The accompanying financial statements are presented in conformity with accounting principles generally accepted in the United States of America ("US GAAP") and pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (the "SEC").

***Concentration of Credit Risk***

Financial instruments that potentially subject the Company to concentrations of credit risk consist of cash accounts in a financial institution, which, at times, may exceed the Federal Deposit Insurance Corporation coverage limit of $250,000. As of December 31, 2021, the Company has not experienced losses on these accounts and management believes the Company is not exposed to significant risks on such accounts.

***Cash and Cash Equivalents***

The Company considers all short-term investments with an original maturity of three months or less when purchased to be cash equivalents. The Company had no cash equivalents as of December 31, 2021.

**AMCI ACQUISITION CORP. II**

**NOTES TO THE FINANCIAL STATEMENTS**

**For the period from January 28, 2021 (inception) through December 31, 2021**

***Use of Estimates***

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of income and expenses during the reporting period. Making estimates requires management to exercise significant judgment. It is at least reasonably possible that the estimate of the effect of a condition, situation or set of circumstances that existed at the date of the financial statements, which management considered in formulating its estimate, could change in the near term due to one or more future confirming events. Accordingly, the actual results could differ significantly from those estimates.

***Investments Held in the Trust Account***

The Company's portfolio of investments is comprised of U.S. government securities, within the meaning set forth in Section 2(a)(16) of the Investment Company Act, with a maturity of 185 days or less, or investments in money market funds that invest in U.S. government securities and generally have a readily determinable fair value, or a combination thereof. When the Company's investments held in the trust account are comprised of U.S. government securities, the investments are classified as trading securities. When the Company's investments held in the trust account are comprised of money market funds, the investments are recognized at fair value. Trading securities and investments in money market funds are presented on the balance sheet at fair value at the end of each reporting period. Gains and losses resulting from the change in fair value of these securities is included in income on investments held in the trust account in the accompanying statement of operations. The estimated fair values of investments held in the trust account are determined using available market information.

***Financial Instruments***

The fair value of the Company's assets and liabilities which qualify as financial instruments under the FASB ASC 820, "Fair Value Measurement," equal or approximate the carrying amounts represented in the balance sheet.

***Fair Value Measurements***

Fair value is defined as the price that would be received for sale of an asset or paid for transfer of a liability, in an orderly transaction between market participants at the measurement date. GAAP establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). These tiers consist of:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Level 1, defined as observable inputs such as quoted prices (unadjusted) for identical instruments in active markets; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable such as quoted prices for similar instruments in active markets or quoted prices for identical or similar instruments in markets that are not active; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions, such as valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable.

In some circumstances, the inputs used to measure fair value might be categorized within different levels of the fair value hierarchy. In those instances, the fair value measurement is categorized in its entirety in the fair value hierarchy based on the lowest level input that is significant to the fair value measurement.

***Offering Costs Associated with Initial Public Offering***

Offering costs consisted of legal, accounting, underwriting fees and other costs incurred through the initial public offering that were directly related to the initial public offering. Offering costs were allocated to the separable financial instruments issued in the initial public offering based on a relative fair value basis, compared to total proceeds received. Offering costs associated with derivative warrant liabilities were expensed as incurred and

------

**AMCI ACQUISITION CORP. II**

**NOTES TO THE FINANCIAL STATEMENTS**

**For the period from January 28, 2021 (inception) through December 31, 2021**

presented as non-operating expenses in the statement of operations. Offering costs associated with the Class A common stock issued were charged against the carrying value of the shares of Class A common stock upon the completion of the initial public offering. The Company classifies deferred underwriting commissions as non-current liabilities as their liquidation is not reasonably expected to require the use of current assets or require the creation of current liabilities.

***Class A Common Stock Subject to Possible Redemption***

The Company accounts for its Class A common stock subject to possible redemption in accordance with the guidance in ASC Topic 480, "Distinguishing Liabilities from Equity." Class A common stock subject to mandatory redemption (if any) is classified as liability instruments and are measured at fair value. Conditionally redeemable Class A common stock (including Class A common stock that features redemption rights that are either within the control of the holder or subject to redemption upon the occurrence of uncertain events not solely within the Company's control) is classified as temporary equity. At all other times, Class A common stock is classified as stockholders' equity. The Company's Class A common stock feature certain redemption rights that are considered to be outside of the Company's control and subject to the occurrence of uncertain future events. Accordingly, as of the initial public offering, 15,000,000 shares of Class A common stock subject to possible redemption are presented at redemption value as temporary equity, outside of the stockholders' equity (deficit) section of the Company's balance sheet.

Under ASC 480-10-S99, the Company has elected to recognize changes in the redemption value immediately as they occur and adjust the carrying value of the security to equal the redemption value at the end of the reporting period. This method would view the end of the reporting period as if it were also the redemption date of the security. Effective with the closing of the initial public offering, the Company recognized the accretion from initial book value to redemption amount, which resulted in charges against additional paid-in capital (to the extent available) and accumulated deficit.

***Derivative Financial Instruments***

The Company does not use derivative instruments to hedge exposures to cash flow, market, or foreign currency risks. The Company evaluates all of its financial instruments, including issued stock purchase warrants, to determine if such instruments are derivatives or contain features that qualify as embedded derivatives, pursuant to ASC 480 and FASB ASC Topic 815, "Derivatives and Hedging" ("ASC 815"). The classification of derivative instruments, including whether such instruments should be recorded as liabilities or as equity, is re-assessed at the end of each reporting period.

The public warrants and the private placement warrants are recognized as derivative liabilities in accordance with ASC 815. Accordingly, the Company recognizes the warrant instruments as liabilities at fair value and adjusts the carrying value of the instruments to fair value at each reporting period until they are exercised. The initial fair value of the public warrants issued in connection with the initial public offering was estimated using a Monte-Carlo simulation model. The fair value of the public warrants as of December 31, 2021 is based on observable listed prices for such warrants. The fair value of the private placement warrants as of December 31, 2021 is determined using a Black-Scholes option pricing model. The determination of the fair value of the warrant liability may be subject to change as more current information becomes available and, accordingly, the actual results could differ significantly. Derivative warrant liabilities are classified as non-current liabilities as their liquidation is not reasonably expected to require the use of current assets or require the creation of current liabilities.

***Income Taxes***

The Company follows the asset and liability method of accounting for income taxes under FASB ASC Topic 740, "Income Taxes" ("ASC 740"). Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the

------

**AMCI ACQUISITION CORP. II**

**NOTES TO THE FINANCIAL STATEMENTS**

**For the period from January 28, 2021 (inception) through December 31, 2021**

period that included the enactment date. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount expected to be realized.

ASC 740 prescribes a recognition threshold and a measurement attribute for the financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more likely than not to be sustained upon examination by taxing authorities. ASC 740 also provides guidance on derecognition, classification, interest and penalties, accounting in period, disclosure and transition. The Company recognizes accrued interest and penalties related to unrecognized tax benefits as income tax expense. The Company is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its position. The Company is subject to income tax examinations by major taxing authorities since inception.

***Net Income (Loss) Per Share of Common Stock***

The Company complies with accounting and disclosure requirements of FASB ASC Topic 260, "Earnings Per Share." The Company has two classes of shares, which are referred to as Class A common stock and Class B common stock. Income and losses are shared pro rata between the two classes of shares. Net income (loss) per common share is calculated by dividing the net income (loss) by the weighted average shares of common stock outstanding for the respective period.

The calculation of diluted net income (loss) does not consider the effect of the warrants underlying the units sold in the initial public offering and the private placement warrants to purchase an aggregate of 11,000,000 shares of Class A common stock in the calculation of diluted income (loss) per share, because their exercise is contingent upon future events and their inclusion would be anti-dilutive under the treasury stock method. As a result, diluted net income (loss) per share is the same as basic net income (loss) per share for the period from January 28, 2021 (inception) through December 31, 2021. Accretion associated with the redeemable Class A common stock is excluded from earnings per share as the redemption value approximates fair value.

The following table reflects presents a reconciliation of the numerator and denominator used to compute basic and diluted net income (loss) per share for each class of common stock:

***Recent Accounting Pronouncements***

In August 2020, the FASB issued Accounting Standards Update ("ASU") No. 2020-06, "Debt — Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging — Contracts in an Entity's Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity's Own Equity" ("ASU 2020-06"), which simplifies accounting for convertible instruments by removing major separation models required under current GAAP. ASU 2020-06 also removes certain settlement conditions that are required for equity-linked contracts to qualify for the derivative scope exception, and it simplifies the diluted earnings per share calculation in certain areas. The Company adopted ASU 2020-06 on August 2, 2021 using the modified retrospective method for transition. Adoption of ASU 2020-06 did not impact the Company's financial position, results of operations or cash flows.

**AMCI ACQUISITION CORP. II**

**NOTES TO THE FINANCIAL STATEMENTS**

**For the period from January 28, 2021 (inception) through December 31, 2021**

The Company's management does not believe that any other recently issued, but not yet effective, accounting standards updates, if currently adopted, would have a material effect on the Company's financial statements.

**Note 3 — Initial Public Offering**

On August 6, 2021, the Company consummated its initial public offering of 15,000,000 units, at an offering price of $10.00 per unit, generating gross proceeds of $150.0 million, and incurring offering costs of approximately $13.8 million, inclusive of $1.5 million of underwriting discount, approximately $5.3 million in deferred underwriting commissions, approximately $6.5 million in fair value of Class B common stock issued to Anchor Investors, and approximately $0.5 million in other offering costs. Each whole warrant entitles the holder to purchase one share of Class A common stock at a price of $11.50 per share, subject to adjustment (see Note 8). Certain qualified institutional buyers or institutional accredited investors (the "Anchor Investors") purchased 15,480,000 units in the initial public offering. None of the Anchor Investors are affiliated with any member of the Company's management.

The underwriters had a 45-day option from the date of the underwriting agreement (August 3, 2021) to purchase up to an additional 2,250,000 units to cover over-allotments. On September 17, 2021, the over-allotment option expired unexercised, resulting in 562,500 shares of Class B common stock that were subject to forfeiture to be forfeited.

**Note 4 — Related Party Transactions**

***Founder Shares***

On January 29, 2021, the Sponsor paid $25,000, or approximately $0.005 per share, to cover certain offering costs in consideration for 5,031,250 shares of Class B common stock, par value $0.0001. In March 2021, the Sponsor transferred all of the founder shares it held to members of the Company's board of directors, management team, and persons or entities affiliated with AMCI Group (the "initial shareholders"). Such shares were fully paid. On May 14, 2021, the Sponsor surrendered 718,750 founder shares to the Company for no consideration, resulting in the Sponsor owning 4,312,500 founder shares. Up to 562,500 of the founder shares will be forfeited depending on the extent to which the underwriters' over-allotment is exercised. On September 17, 2021, the over-allotment option expired unexercised, resulting in 562,500 of the founder shares being forfeited.

In exchange for the Anchor Investors' participation in the initial public offering as described in Note 3, the Sponsor sold a total of 780,000 founder shares to the Anchor Investors. The Company determined that the fair value of these founder shares was approximately $6.5 million (or approximately $8.35 per share) using a Monte Carlo simulation. The Company recognized the excess fair value of these founder shares, over the price sold to the Anchor Investors, as an expense of the initial public offering resulting in a charge against the carrying value of Class A common stock subject to possible redemption.

The initial stockholders have agreed not to transfer, assign or sell any of their founder shares and any Class A common stocks issuable upon conversion thereof until the earlier to occur of: (A) one year after the completion of the initial business combination and (B) the date on which the Company completes a liquidation, merger, capital stock exchange or other similar transaction after the Company's initial business combination that results in all of the Company's stockholders having the right to exchange their Class A common stock for cash, securities or other property; except to certain permitted transferees and under certain circumstances (the "Lock-up"). Any permitted transferees will be subject to the same restrictions and other agreements of the company's initial stockholders with respect to any founder shares. Notwithstanding the foregoing, the founder shares will be released from the Lock-up if the closing price of the Company's Class A common stock equals or exceeds $12.00 per share (as adjusted for stock splits, stock capitalizations, reorganizations, recapitalizations and the like) for any 20 trading days within any 30-trading day period commencing at least 150 days after the company's initial business combination.

**NOTES TO THE FINANCIAL STATEMENTS**

**For the period from January 28, 2021 (inception) through December 31, 2021**

***Private Placement***

Simultaneously with the closing of the initial public offering, the Company's Sponsor has purchased an aggregate of 3,500,000 private placement warrants, each exercisable to purchase one Class A common stock at $11.50 per share, at a price of $1.00 per warrant, or $3,500,000 in the aggregate.

The private placement warrants will not be redeemable by the Company so long as they are held by the initial purchasers or their permitted transferees. The initial purchasers, or their permitted transferees, have the option to exercise the private placement warrants on a cashless basis. If the private placement warrants are held by holders other than initial purchasers or their permitted transferees, the private placement warrants will be redeemable by the Company and exercisable by the holders on the same basis as the warrants included in the units being sold in the initial public offering. Otherwise, the private placement warrants have terms and provisions that are identical to those of the warrants being sold as part of the units in the initial public offering.

If the private placement warrants are held by holders other than the Sponsor or its permitted transferees, the private placement warrants will be redeemable by the Company in all redemption scenarios and exercisable by the holders on the same basis as the warrants included in the units being sold in the initial public offering.

***Related Party Loans and Advances***

On January 29, 2021, the Sponsor agreed to loan the Company up to $300,000 to be used for a portion of the expenses of the initial public offering ("Note"). This loan was non-interest bearing, unsecured and payable upon the closing of the initial public offering. In addition to the Note, the Sponsor of the Company also paid certain administrative expenses and offering costs on behalf of the Company. These advances were due on demand and were non-interest bearing. The Company repaid the note payable and advances in exchange for the issuance of private placement warrants.

In addition, in order to finance transaction costs in connection with an intended business combination, the Sponsor or an affiliate of the Sponsor, or certain of the Company's officers and directors may, but are not obligated to, loan the Company funds as may be required on a non-interest basis ("Working Capital Loans"). If the Company completes the initial business combination, it will repay the Working Capital Loans. In the event that the initial business combination does not close, the Company may use a portion of the working capital held outside the trust account to repay the Working Capital Loans but no proceeds from the trust account would be used to repay the Working Capital Loans. Up to $1,500,000 of such Working Capital Loans may be convertible into warrants of the post-business combination entity at a price of $1.00 per warrant at the option of the lender. Such warrants would be identical to the private placement warrants. Except as set forth above, the terms of Working Capital Loans, if any, have not been determined and no written agreements exist with respect to such loans. As of December 31, 2021, the Company had no borrowings under the Working Capital Loans.

***Administrative Service Fee***

warrants and (iii) private placement warrants that may be issued upon conversion of Working Capital Loans will have registration rights to require the Company to register a sale of any of its securities held by them prior to the consummation of the initial business combination pursuant to a registration rights agreement to be signed prior to or on the effective date of the initial public offering. The holders of these securities are entitled to make up to three demands, excluding short form demands, that the Company registers such securities.

***Underwriting Agreement***

The Company granted the underwriters a 45-day option from the date of the underwriting agreement to purchase up to an additional 2,250,000 units to cover over-allotments, if any. On September 17, 2021, the over-allotment option expired unexercised, resulting in the forfeiture of 562,500 shares of founder shares.

The underwriters were paid an underwriting discount of one percent (1%) of the gross proceeds of the initial public offering, or $1,500,000. Additionally, the underwriters will be entitled to a deferred underwriting discount of 3.5% of the gross proceeds, or $5,250,000, of the initial public offering upon the completion of the Company's initial business combination.

**NOTES TO THE FINANCIAL STATEMENTS**

**For the period from January 28, 2021 (inception) through December 31, 2021**

**Class B Common Stock** — The Company is authorized to issue 20,000,000 Class B common stock with a par value of $0.0001 per share. As of December 31, 2021, there were 3,750,000 shares of Class B common stock issued and outstanding (see Note 4).

Holders of Class A common stock and holders of Class B common stock will vote together as a single class on all matters submitted to a vote of the Company's stockholders except as required by law. Unless specified in the Company's amended and restated certificate of incorporation, or as required by applicable provisions of the Delaware General Corporation Law ("DGCL") or applicable stock exchange rules, the affirmative vote of a majority of the Company's shares of common stock that are voted is required to approve any such matter voted on by its stockholders.

The Class B common stock will automatically convert into shares of Class A common stock concurrently with or immediately following the consummation of the initial business combination on a one-for-one basis, subject to adjustment for stock splits, stock dividends, reorganizations, recapitalizations and the like, and subject to further adjustment as provided herein. In the case that additional shares of Class A common stock or equity-linked securities are issued or deemed issued in connection with the initial business combination, the number of shares of Class A common stock issuable upon conversion of all founder shares will equal, in the aggregate, on an as-converted basis, 20% of the total number of shares of Class A common stock outstanding after such conversion (after giving effect to any redemptions of shares of Class A common stock by public stockholders), including the total number of shares of Class A common stock issued, or deemed issued or issuable upon conversion or exercise of any equity-linked securities or rights issued or deemed issued, by the Company in connection with or in relation to the consummation of the initial business combination, excluding any shares of Class A common stock or equity-linked securities or rights exercisable for or convertible into shares of Class A common stock issued, or to be issued, to any seller in the initial business combination and any private placement warrants issued to the Sponsor, officers or directors upon conversion of working capital loans, provided that such conversion of founder shares will never occur on a less than one-for-one basis.

**Note 8 — Warrants**

As of December 31, 2021, in connection with the initial public offering, the Company has 7,500,000 public warrants and 3,500,000 private placement warrants outstanding.

Each whole warrant entitles the registered holder to purchase one share of Class A common stock at a price of $11.50 per share, subject to adjustment as discussed below, at any time commencing 30 days after the completion of the initial business combination, provided that the Company has an effective registration statement under the Securities Act covering the shares of Class A common stock issuable upon exercise of the warrants and a current prospectus relating to them is available (or the Company permits holders to exercise their warrants on a cashless basis under the circumstances specified in the warrant agreement) and such shares are registered, qualified or exempt from registration under the securities, or blue sky, laws of the state of residence of the holder. The warrants will expire five years after the completion of the Company's initial business combination, at 5:00 p.m., New York City time, or earlier upon redemption or liquidation.

The Company has agreed that as soon as practicable, but in no event later than fifteen (15) business days after the closing of the initial business combination, it will use its best efforts to file with the SEC a registration statement for the registration, under the Securities Act, of the Class A common stock issuable upon exercise of the warrants. The Company will use its best efforts to cause the same to become effective and to maintain the effectiveness of such registration statement, and a current prospectus relating thereto, until the expiration of the warrants in accordance with the provisions of the warrant agreement. If a registration statement covering the shares of Class A common stock issuable upon exercise of the warrants is not effective by the sixtieth (60th) business day after the closing of the initial business combination, warrant holders may, until such time as there is an effective registration statement and during any period when the Company will have failed to maintain an effective registration statement, exercise warrants on a "cashless basis" in accordance with Section 3(a)(9) of the Securities Act or another exemption. Notwithstanding the above, if the Company's Class A common stock are at the time of any exercise of a warrant not listed on a national securities exchange such that they satisfy the definition of a "covered security" under Section 18(b)(1) of the Securities Act, the Company may, at its option, require holders of public warrants who

**AMCI ACQUISITION CORP. II**

**NOTES TO THE FINANCIAL STATEMENTS**

**For the period from January 28, 2021 (inception) through December 31, 2021**

exercise their warrants to do so on a "cashless basis" in accordance with Section 3(a)(9) of the Securities Act and, in the event the Company so elect, it will not be required to file or maintain in effect a registration statement, and in the event the Company do not so elect, it will use its best efforts to register or qualify the shares under applicable blue sky laws to the extent an exemption is not available.

Redemption of warrants when the price per share of Class A common stock equals or exceeds $18.00.

Once the warrants become exercisable, the Company may redeem the outstanding warrants:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• in whole and not in part;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• at a price of $0.01 per warrant;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• upon a minimum of 30 days' prior written notice of redemption to each warrant holder; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• if, and only if, the closing price of the Class A common stock equals or exceeds $18.00 per share (as adjusted for adjustments to the number of shares issuable upon exercise or the exercise price of a warrant as described under the heading "— Warrants — Public Stockholders' Warrants — Anti-Dilution Adjustments") for any 20 trading days within a 30-trading day period ending three trading days before we send the notice of redemption to the warrant holders.

Redemption of warrants when the price per share of Class A common stock equals or exceeds $10.00.

Once the warrants become exercisable, the Company may redeem the outstanding warrants:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• in whole and not in part;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• at $0.10 per warrant upon a minimum of 30 days' prior written notice of redemption provided that holders will be able to exercise their warrants on a cashless basis prior to redemption and receive that number of shares determined by reference to the table below, based on the redemption date and the "fair market value" (as defined below) of our Class A common stock except as otherwise described below; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• if, and only if, the closing price of our Class A common stock equals or exceeds $10.00 per public share (as adjusted for adjustments to the number of shares issuable upon exercise or the exercise price of a warrant as described under the heading "— Warrants — Public Stockholders' Warrants — Anti-Dilution Adjustments") for any 20 trading days within the 30-trading day period ending three trading days before we send the notice of redemption to the warrant holders.

In addition, if (x) the Company issue additional shares of Class A common stock or equity-linked securities for capital raising purposes in connection with the closing of our initial business combination at an issue price or effective issue price of less than $9.20 per share (with such issue price or effective issue price to be determined in good faith by the Company's board of directors and, in the case of any such issuance to the Sponsor or its affiliates, without taking into account any founder shares held by the Sponsor or such affiliates, as applicable, prior to such issuance) (the "Newly Issued Price"), (y) the aggregate gross proceeds from such issuances represent more than 60% of the total equity proceeds, and interest thereon, available for the funding of our initial business combination on the date of the consummation of the initial business combination (net of redemptions), and (z) the volume weighted average trading price of the Company's Class A common stock during the 20 trading day period starting on the trading day prior to the day on which the Company consummate the initial business combination (such price, the "Market Value") is below $9.20 per share, the exercise price of the warrants will be adjusted (to the nearest cent) to be equal to 115% of the higher of the Market Value and the Newly Issued Price, the $18.00 per share redemption trigger price described above under "— Redemption of warrants when the price per share of Class A common stock equals or exceeds $18.00" will be adjusted (to the nearest cent) to be equal to 180% of the higher of the Market Value and the Newly Issued Price, and the $10.00 per share redemption trigger price described above under "— Redemption of warrants when the price per share of Class A common stock equals or exceeds $10.00" will be adjusted (to the nearest cent) to be equal to the higher of the Market Value and the Newly Issued Price.

**Note 9 — Fair Value Measurement** 

The following table presents information as of December 31, 2021 about the Company's financial assets and liabilities that are measured at fair value on a recurring basis by level within the fair value hierarchy:

---

| | | | |
|:---|:---|:---|:---|
| **Description** | **Quoted Prices in Active<br>Markets<br>(Level 1)** | **Significant Other<br>Observable Inputs<br>(Level 2)** | **Significant Other<br>Unobservable Inputs<br>(Level 3)** |
| **Assets:** | | | |
| Investments held in Trust Account | $150006015 | $— | $— |
| **Liabilities:** |  |  |  |
| Derivative liabilities – Public Warrants | $3825000 | $— | $— |
| Derivative liabilities – Private Placement Warrants | $— | $— | $1785000 |

---

Transfers to/from Levels 1, 2 and 3 are recognized at the beginning of the reporting period. The estimated fair value of public warrants was transferred from a Level 3 fair value measurement to a Level 1 measurement, when the public warrants were separately listed and traded in September 2021. There were no other transfers between levels in the period from January 28, 2021 (inception) through December 31, 2021.

Level 1 assets include investments in mutual funds invested in U.S. government securities and derivative warrant liabilities (public warrants). The Company uses inputs such as actual trade data, quoted market prices from dealers or brokers, and other similar sources to determine the fair value of its investments.

For periods where no observable traded price is available, the fair value of the public warrants has been estimated using a Monte-Carlo simulation model and the private placement warrants has been estimated using a Black-Scholes option pricing model. For periods subsequent to the detachment of the public warrants from the units, the fair value of the public warrants is based on the observable listed price for such warrants. The estimated fair value of the public and private placement warrants, prior to the public warrants being traded in an active market, was determined using Level 3 inputs. Inherent in a Monte-Carlo simulation and Black-Scholes option pricing model are assumptions related to the unit price, expected volatility, risk-free interest rate, term to expiration, and dividend yield. The unit price is based on the publicly traded price of the units as of the measurement date. The Company estimated the volatility for the public and private placement warrants based on the implied volatility from the traded prices of warrants issued by other special purpose acquisition companies. The risk-free interest rate is based on interpolated U.S. Treasury rates, commensurate with a similar term to the public and private placement warrants. The expected life of the warrants is assumed to be equivalent to their remaining contractual term. Finally, the Company does not anticipate paying a dividend. Any changes in these assumptions can change the valuation significantly.

The following table provides quantitative information regarding Level 3 fair value measurements inputs at their measurement dates:

---

| | | |
|:---|:---|:---|
| | **As of <br>December 31, 2021** | **As of <br>August 6, 2021** |
| Exercise price | $11.50 | $11.50 |
| Volatility | 9.6% | 11.3% |
| Stock price | $9.66 | $9.66 |
| Remaining term (yrs) | 5.75 | 6.51 |
| Risk-free rate | 1.32% | 0.99% |

**Note 10 — Income Taxes**

The Company files income tax returns in the U.S. federal and Connecticut jurisdictions and are subject to examination. The income tax provision consists of the following:

---

|:---|:---|

| &nbsp;&nbsp;&nbsp;&nbsp;State |  |
| Valuation allowance | 290181 |
| Income tax provision | $— |

---

The Company's net deferred tax assets are as follows:

---

| | |
|:---|:---|
| | **December 31, 2021** |
| Deferred tax assets: |  |
| Start-up/Organization costs | $210307 |
| Net operating loss carryforwards | 79874 |
| Total deferred tax assets | 290181 |
| Valuation allowance | (290181) |
| Deferred tax asset, net of allowance | $— |

---

In assessing the realization of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which temporary differences representing net future deductible amounts become deductible. Management considers the scheduled reversal of deferred tax assets, projected future taxable income and tax planning strategies in making this assessment. After consideration of all of the information available, management believes that significant uncertainty exists with respect to future realization of the deferred tax assets and has therefore established a full valuation allowance. For the period from January 28, 2021 (inception) through December 31, 2021, the valuation allowance was $290,181. As of December 31, 2021, the Company had $380,351 of U.S. federal net operating loss carryovers, which do not expire, available to offset future taxable income.

| Change in valuation allowance | 620.9% |
| Income tax expense | 0.0% |

**Note 11 — Subsequent Events**

The Company evaluated subsequent events and transactions that occurred up to the date financial statements were issued. Based upon this review, the Company did not identify any subsequent events that would have required adjustment or disclosure in the financial statements.

On March 8, 2022, the Company entered into the Merger Agreement with Merger Sub and LanzaTech. The transactions contemplated by the Merger Agreement are referred to herein as the "Business Combination." The time of the closing of the Business Combination is referred to herein as the "Closing." The date of the Closing of the Business Combination is referred to herein as the "Closing Date."

***Proposed Business Combination***

If the Business Combination is approved by the Company's stockholders and LanzaTech's stockholders, and the closing conditions in the Merger Agreement are satisfied or waived, then, among other things, upon the terms and subject to the conditions of the Merger Agreement and in accordance with Delaware General Corporation Law, Merger Sub will merge with and into LanzaTech, with LanzaTech surviving the merger as the Company's wholly owned subsidiary (the "Merger"). In connection with the consummation of the Merger, the Company will be renamed "LanzaTech Global, Inc." and is referred to herein as "New LanzaTech" as of the time following such change of name.

Under the Merger Agreement, the Company has agreed to acquire all of the outstanding equity interests of LanzaTech for consideration consisting of equity interests of New LanzaTech valued at $1,817,000,000 in the aggregate. The consideration to be paid to holders of shares of LanzaTech capital stock will be shares of common stock of New LanzaTech ("New LanzaTech Common Stock"), valued at $10.00 per share, to be paid at the closing of the Merger. The number of shares of New LanzaTech Common Stock payable in the Merger in respect of each share of LanzaTech capital stock (each, a "LanzaTech Share") will be determined based on the exchange ratio (the "Exchange Ratio"), and certain corresponding adjustments, in each case as set forth in the Merger Agreement.

Pursuant to the Merger Agreement, at Closing: (i) each warrant to purchase LanzaTech Shares (each, a "LanzaTech Warrant") that is outstanding and unexercised immediately prior to Closing and would automatically be exercised or exchanged in full in accordance with its terms by virtue of the occurrence of the Merger, will be so automatically exercised or exchanged in full for the applicable LanzaTech Shares, and each such LanzaTech Share will be treated as being issued and outstanding immediately prior to Closing and will be canceled and converted into the right to receive the applicable shares of New LanzaTech Common Stock; and (ii) each LanzaTech Warrant that

------

**AMCI ACQUISITION CORP. II**

**NOTES TO THE FINANCIAL STATEMENTS**

**For the period from January 28, 2021 (inception) through December 31, 2021**

is outstanding and unexercised immediately prior to the Closing and is not automatically exercised in full as described in clause (i) will be converted into a warrant to purchase shares of New LanzaTech Common Stock, in which case (a) the number of shares underlying such New LanzaTech warrant (each, a "New LanzaTech Warrant") will be determined by multiplying the number of LanzaTech Shares subject to such warrant immediately prior to Closing, by the Exchange Ratio and (b) the per share exercise price of such New LanzaTech Warrant will be determined by dividing the per share exercise price of such LanzaTech Warrant immediately prior to the Effective Time by the Exchange Ratio, except that in the case of certain warrants specified in the Merger Agreement, such exercise price will be $10.00.

Pursuant to the Merger Agreement, at Closing, each option to purchase LanzaTech Shares (each, a "LanzaTech Option") will be converted into an option to purchase a number of shares of New LanzaTech Common Stock (rounded down to the nearest whole share) equal to the product of (i) the number of LanzaTech Shares subject to such LanzaTech Option multiplied by (ii) the Exchange Ratio. The exercise price of such New LanzaTech option will be equal to the quotient of (a) the exercise price per share of such LanzaTech Option in effect immediately prior to the Effective Time divided by (b) the Exchange Ratio (and as so determined, this exercise price will be rounded up to the nearest full cent).

Pursuant to the Merger Agreement, at Closing, each award of restricted shares of LanzaTech common stock (each, a "LanzaTech RSA") that is outstanding immediately prior to the Effective Time will be converted into an award of restricted shares of New LanzaTech Common Stock (each, a "New LanzaTech RSA") on the same terms and conditions as were applicable to such LanzaTech RSA immediately prior to the Effective Time, except that such New LanzaTech RSA will relate to a number of shares of New LanzaTech Common Stock equal to the number of LanzaTech Shares subject to such LanzaTech RSA, multiplied by the Exchange Ratio.

The closing of the Merger is subject to certain customary conditions, including, among others, (i) adoption by AMCI's stockholders and LanzaTech's stockholders of the Merger Agreement and their approval of certain other actions related to the Business Combination, (ii) the expiration or termination of the waiting period (or any extension thereof) applicable to the transactions contemplated by the Merger Agreement and any ancillary agreements, in each case under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, (iii) the effectiveness of a registration statement on Form S-4 (the "Registration Statement") under the Securities Act of 1933, as amended (the "Securities Act") with respect to the shares of New LanzaTech Common Stock to be paid as consideration in the Merger, (iv) there being no government order or law enjoining, prohibiting or making illegal the consummation of the Merger or the transactions contemplated by the Merger Agreement, (v) AMCI having at least $5,000,001 of net tangible assets (as determined in accordance with Rule 3a51-1(g)(1) under the Exchange Act) after giving effect to any payments required to be made in connection with the redemption of AMCI's public shares and the proceeds from the Subscription Agreements described below, (vi) AMCI having at least $230,000,000 of cash at the closing of the Merger, consisting of cash held in AMCI's trust account after taking into account any redemption of AMCI's public shares, and the proceeds from the Subscription Agreements described below, net of transaction expenses of AMCI and LanzaTech, and (vii) the listing on Nasdaq of the shares of New LanzaTech Common Stock issued in connection with the Business Combination.

**LANZATECH NZ, INC.**

**NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)**

**Note 1 — Description of the Business**

The reporting entity is LanzaTech NZ, Inc. (formerly known as LanzaTech New Zealand Limited) and its subsidiaries (collectively, "the Company" or "LanzaTech"). LanzaTech NZ, Inc. is a profit-oriented entity previously incorporated in New Zealand. Effective October 28, 2021, LanzaTech New Zealand Limited filed a Certificate of Incorporation to migrate its country of domicile from New Zealand to Delaware, in the United States, and change its corporate name to "LanzaTech NZ, Inc." The amendment was approved by the Board of Directors of LanzaTech and was effected by the filing of a Certificate of Incorporation with the Delaware Secretary of State. The registered office location is c/o The Corporation Trust Company, Corporation Trust Center, 1209 Orange Street, Wilmington, Delaware, 19801. The Company licenses its technology to customers, performs research and development in biotechnology, and provides engineering and other related services for commercial and government customers. Using the Company's proprietary fermentation technology, the Company's customers can convert certain carbon-rich waste gases into fuels and chemicals. The Company employs a licensing business model whereby its customers build, own and operate facilities that use the Company's technology, and in return, the Company is paid royalties based on the revenue generated from the use of its technology. In 2018, the Company, through its partners, launched the world's first commercial waste gas to ethanol plant in China, followed by a second one in 2021, also in China, with others currently in development in various countries.

***Proposed Merger***

On March 8, 2022, the Company entered into an Agreement and Plan of Merger (the "Merger Agreement") with AMCI Acquisition Corp. II, a Delaware corporation ("AMCI") and AMCI Merger Sub, Inc., a Delaware corporation and a wholly owned subsidiary of AMCI ("Merger Sub"). Under the Merger Agreement, Merger Sub will merge with and into LanzaTech, with LanzaTech surviving the Merger as a wholly-owned subsidiary of AMCI ("the Business Combination"). In connection with the Business Combination, AMCI will be renamed LanzaTech Global, Inc. ("New LanzaTech"). AMCI has agreed to acquire all of the outstanding equity interests of LanzaTech for consideration consisting of an equity interest of New LanzaTech valued at approximately $1.8 billion. Completion of the transaction is subject to certain customary regulatory consents and approval by stockholders of AMCI and the Company.

The Merger Agreement was amended on December 7, 2022, to provide for, among other things, (i) the inclusion of the aggregate net proceeds from each of the AM SAFE Note and Brookfield SAFE in the Acquiror Closing Cash Amount, (ii) the reduction of the Minimum Closing Cash Condition from $250,000,000 to $230,000,000, (iii) the clarification that, to the extent that the Brookfield SAFE remains unexercised at Closing, it will be assumed by AMCI, remain in effect on the same terms and conditions as are in effect prior to the Closing and thereafter entitle the holder thereof to be issued shares of common stock in AMCI after the Closing, (iv) the clarification that, in the event that it becomes reasonably apparent to the parties that the Acquiror Closing Cash Amount will be less than the Minimum Closing Cash Condition, AMCI will use commercially reasonable efforts to enter into non-redemption agreements, or similar agreements, as may be necessary to satisfy the Minimum Closing Cash Condition, (v) the extension of the outside date applicable to the Closing from December 7, 2022 to February 28, 2023 and (vi) the elimination of LanzaTech's right to terminate the agreement in the event that we fail to, on or prior to July 7, 2022, enter into one or more additional subscription agreements or non-redemption agreements as a result of which the sum of the PIPE Investment Amount (including net proceeds under the AM SAFE Note to LanzaTech) and the aggregate number of shares of Class A common stock subject to non-redemption agreements multiplied by $10.00, minus certain transaction expenses and other liabilities at Closing, would be equal to at least the Minimum Closing Cash Condition.

In connection with the Merger Agreement, AMCI entered into subscription agreements with certain investors pursuant to which AMCI agreed to issue and sell a private placement to close immediately prior to the Business Combination.

**Note 2 — Summary of Significant Accounting Policies** 

***Basis of Presentation and Principles of Consolidation***

The accompanying unaudited condensed consolidated financial statements of LanzaTech NZ Inc. have been prepared in accordance with generally accepted accounting principles for interim financial information, and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by accounting principles generally accepted in the United States of America ("US GAAP"), the accounting principles, standards, and procedures adopted by the U.S. Securities and Exchange Commission, for complete financial statements. However, in the opinion of management, all adjustments (consisting of normal recurring accruals) have been made that are necessary for a fair presentation of the condensed consolidated financial statements for the interim periods. For further information refer to the Consolidated Financial Statements and Footnotes thereto included in the Company's Annual Report for the year ended December 31, 2021.

The Company uses a qualitative approach in assessing the consolidation requirement for variable interest entities ("VIEs"). This approach focuses on determining whether the Company has the power to direct the activities of the VIE that most significantly affect the VIE's economic performance and whether the Company has the obligation to absorb losses, or the right to receive benefits, that could potentially be significant to the VIE.

The Company holds interests in certain VIEs for which it has been determined the Company is not the primary beneficiary. The Company's variable interests primarily relate to entities in which the Company has a non-controlling equity interest. Although these financial arrangements resulted in holding variable interests in these entities, they did not empower the Company to direct the activities of the VIEs that most significantly impact the VIEs' economic performance. The Company's interests in the VIEs are, therefore, accounted for under the equity method of accounting or alternative measurement. Refer to Note 5, *Investments*, for further information. The Company is exposed to the VIEs' losses and other impairment indicators up to the carrying value of each investment and any amounts receivable from the VIE, less amounts payable. Refer to Note 9, *Related Party Transactions*, for further details on the transactions with VIEs.

***Going Concern***

The accompanying condensed consolidated financial statements of the Company have been prepared assuming the Company will continue as a going concern and in accordance with accounting principles generally accepted in the United States of America ("US GAAP"). The going concern basis of presentation assumes that the Company will continue in operation one year after the date these financial statements are issued and will be able to realize its assets and discharge its liabilities and commitments in the normal course of business. The Company had cash and cash equivalents of $50,370 and an accumulated deficit of $(434,863) at September 30, 2022 and cash outflows from operations of $(71,336) and a net loss of $(54,974) for the nine months ended September 30, 2022.

The Company has historically funded its operations through debt financing and issuance of equity securities. Based on the Company's financial position as of the date these condensed consolidated financial statements were available to be issued, the Company projects that it will be able to cover its liquidity needs for the next twelve months with cash on hand. Accordingly, the Company's condensed consolidated financial statements have been prepared on the basis that it will continue as a going concern.

***Use of Estimates***

The preparation of financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements, and the reported amounts of revenues and expenses during the reporting period. Significant estimates include fair value of equity awards granted to both employees and non-employees, the SAFE and the SAFE warrants.

Changes in facts and circumstances or additional information may result in revised estimates, and actual results may differ from these estimates.

------

***Segment Information***

The Company operates as one operating segment which is the licensing of its technologies and related services such as research and development and engineering. The Chief Executive Officer who is the chief operating decision maker, reviews financial information on an aggregate basis for allocating resources and evaluating financial performance. Substantially all of the Company's long-lived assets are maintained in the United States.

***Foreign Currencies***

The Company's reporting currency is the U.S. Dollar. The Company has certain foreign subsidiaries where the functional currency is the local currency. All of the assets and liabilities of these subsidiaries are converted to U.S. dollars at the exchange rate in effect at the balance sheet date, income and expense accounts are translated at average rates for the period, and shareholder's equity accounts are translated at historical rates. The effects of translating financial statements of foreign operations into our reporting currency are recognized as an adjustment in accumulated other comprehensive income (loss).

The Company also has foreign subsidiaries that have a functional currency of the U.S. dollar. Purchases and sales of assets and income and expense items denominated in foreign currencies are remeasured into U.S. dollar amounts on the respective dates of such transactions. Net realized foreign currency gains or losses relating to the differences between these recorded amounts and the U.S. dollar equivalent actually received or paid are included within Other (expense) income, net in the condensed consolidated statements of operations and comprehensive loss.

***Cash and Cash Equivalents***

The Company considers all highly liquid investments with an original maturity of three months or less at the time of purchase to be cash equivalents. As of September 30, 2022 and December 31, 2021, the Company had $50,370 and $128,318 of cash and cash equivalents, respectively.

***Restricted Cash and Other Cash Flows from Operating Activities***

The Company is required to maintain a cash deposit with a bank which consists of collateral on certain travel and expense programs maintained by the bank. The following represents a reconciliation of cash and cash equivalents in the condensed consolidated balance sheets to total cash, cash equivalents and restricted cash in the condensed consolidated statements of cash flows as of September 30, 2022 and December 31, 2021 (in thousands).

---

| | | |
|:---|:---|:---|
| | **As of** | **As of** |
| | **September 30, 2022** | **December 31, 2021** |
| Cash and cash equivalents | $50370 | $128318 |
| Restricted cash (presented within Other current assets) | 664 | 414 |
| Cash, cash equivalents and restricted cash | $51034 | $128732 |

---

***Trade and Other Receivables***

Receivables are reported net of allowances for doubtful accounts. The Company maintains allowances for doubtful accounts for estimated losses resulting from the inability of customers to make required payments. The Company estimates the allowance for doubtful accounts based on a variety of factors including the length of time receivables are past due, the financial health of customers, unusual macroeconomic conditions, and historical experience. As of September 30, 2022 and December 31, 2021, the Company recognized an allowance for doubtful accounts of $1,051 and $1,235, respectively.

***Revenue Recognition***

The Company recognizes revenue in accordance with Accounting Standards Codification ("ASC") 606, *Revenue from Contracts with Customers*. The Company primarily earns revenue from services related to feasibility studies and basic engineering design of commercial plants, licensing of technologies, joint development and contract

------

research activities to develop novel biocatalysts and related technologies, and sale of CarbonSmart ethanol produced using the Company's proprietary technologies.

Revenue is measured based on the consideration specified in a contract with a customer. The Company records taxes collected from customers and remitted to governmental authorities on a net basis. The Company's payment terms are between 30-60 days and can vary by customer type and products offered. Management has evaluated the terms of our arrangements and determined that they do not contain significant financing components.

*Carbon Capture and Transformation*

The Company provides feasibility studies and basic design and engineering services used for detailed design, procurement, and construction of commercial plants that utilize the Company's technologies, along with the sale of equipment and microbes. The services provided are recognized as a performance obligation satisfied over time. Revenue is recognized using the output method based on milestone completion, the cost-to-cost input method for certain engineering services, or the percentage of completion method as performance obligations are satisfied. Management has determined that the milestone completion and the associated contractual payment amounts are an appropriate measure of progress towards complete satisfaction of the performance obligations under ASC 606.

The Company licenses intellectual property to generate recurring revenue when its customers deploy carbon capture and transformation plants. When licenses are considered to be distinct performance obligations, the recognition of revenue is dependent on the terms of the contract, which may include fixed consideration or royalties based on sales or usage, in which case, the revenue is recognized when the subsequent sale or usage occurs or when the performance obligation to which some or all of the sales or usage-based royalty is allocated has been satisfied, whichever is later.

*Research and Development Services*

The Company performs research and development ("R&D") services related to novel technologies and development of biocatalysts for commercial applications, mainly to produce fuels and chemicals. The Company engages in two main types of R&D services – joint development agreements, and other contract research, including projects with the U.S. Department of Energy. Such services are recognized as a performance obligation satisfied over time. Revenue is recognized based on milestone completion, when payments are contingent upon the achievement of such milestones, or based on percentage-completion method when enforceable rights to payment exist. When no milestones or phases are clearly defined, management has determined that the cost incurred, input method, is an appropriate measure of progress towards complete satisfaction of the performance obligations under ASC 606, *Revenue from Contracts with Customers*, and estimates its variable consideration under the expected value method.

Revenue is not recognized in advance of customer acceptance of a milestone when such acceptance is contractually required. Payments for R&D services with no contractual payments are not due from customers until a technical report is submitted; therefore, a contract asset is recognized at milestone completion but prior to the submission of a technical report. The contract asset represents the Company's right to consideration for the services performed at milestone completion. Occasionally, customers provide payments in advance of the Company providing services which creates a contract liability for the Company. The contract liability represents the Company's obligation to provide services to a customer.

***Collaboration Arrangements***

The Company has certain partnership agreements that are within the scope of ASC 808, *Collaborative Arrangements*, which provides guidance on the presentation and disclosure of collaborative arrangements. Generally, the classification of the transactions under the collaborative arrangements is determined based on the nature of the contractual terms of the arrangement, along with the nature of the operations of the participants. The Company's collaborative agreements generally include a provision of R&D services related to novel technologies and biocatalysts. Amounts received for these services are classified as Revenue from collaborative arrangements in the condensed consolidated statements of operations and comprehensive loss. The Company's R&D services are a major part of the Company's ongoing operations and therefore ASC 606 is applied to recognize revenue.

------

***CarbonSmart***

The Company's CarbonSmart business, initially CarbonSmart ethanol, is produced by LanzaTech licensed plants using the Company's proprietary technologies. Customers can buy CarbonSmart ethanol directly from LanzaTech, which the Company sources from these partnering plants. Revenue is recognized at a point in time when control transfers to the customer, which varies depending on the shipping terms. The Company acts as the principal in such transactions and accordingly, recognizes revenue and cost of revenues on a gross basis.

***Fair Value of Financial Instruments***

Fair value is defined as the exchange price that would be received for an asset or an exit price paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The fair value hierarchy defines a three-level valuation hierarchy for disclosure of fair value measurements as follows:

**Level 1** — Valuations based on quoted prices in active markets for identical assets or liabilities that an entity has the ability to access;

**Level 2** — Valuations based on quoted prices for similar assets or liabilities, quoted prices for identical assets or liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable data for substantially the full term of the assets or liabilities; and

**Level 3** — Valuations based on inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

The categorization of a financial instrument within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement.

The fair value of the Company's assets and liabilities, which qualify as financial instruments under ASC Topic 820, *Fair Value Measurement*, approximates the carrying amounts represented in the accompanying condensed consolidated balance sheets, primarily due to their short-term nature, except for the warrant liability.

***Concentration of Credit Risk and Other Risks and Uncertainties***

Revenue generated from the Company's customers outside of the United States for the nine months ended September 30, 2022 and 2021 was approximately 61% and 65%, respectively.

As of September 30, 2022 and December 31, 2021, approximately 35% and 35%, respectively, of trade accounts receivable and unbilled accounts receivable was due from customers located outside the United States. At September 30, 2022 and December 31, 2021, the value of property, plant, and equipment outside the United States was immaterial.

The Company's revenue by geographic region based on the customer's location is presented in Note 4, *Revenues*.

***Recently Announced Accounting Pronouncements***

In October 2020, the Financial Accounting Standard Board ("FASB") issued an Accounting Standard Update ("ASU") No. 2020-10, *Codification Improvements* ("ASU 2020-10"). The standard contains improvements to the FASB Accounting Standards Codification (the "Codification") by ensuring that all guidance that requires or provides an option for an entity to provide information in the notes to financial statements is codified in the disclosure section of the Codification. The standard also improves various topics in the Codification so that entities can apply guidance more consistently on codifications that are varied in nature where the original guidance may have been unclear. The amendments in ASU 2020-10 were effective for the Company for fiscal years beginning after December 15, 2021, and interim periods within fiscal years beginning after December 15, 2022. Early adoption was permitted. There were no material impacts upon the adoption of ASU 2020-10, on its consolidated financial statements and related disclosures.

**Note 3 — Net Loss Per Share**

Basic net loss per share is computed by dividing net loss by the weighted-average number of shares of common stock of the Company outstanding during the period. Diluted net loss per share is computed by giving effect to all potential shares of common stock of the Company, including outstanding stock options, warrants, and contingently redeemable preferred stock, to the extent dilutive.

The following table presents the calculation of basic and diluted net loss per share for the Company's common stock (in thousands, except shares and per share amounts):

__________________

(1)In periods in which the Company reports a net loss, all share-based compensation awards are excluded from the calculation of diluted weighted average shares outstanding because of their anti-dilutive effect on earnings (loss) per share.

------

As of September 30, 2022 and 2021, potential shares of common stock not included in the computation of loss per share because their effect would be antidilutive include the following:

---

| | | |
|:---|:---|:---|
| | **Nine months ended September 30,** | **Nine months ended September 30,** |
| | **2022** | **2021** |
| Redeemable convertible preferred stock (if converted) | 29521810 | 29521810 |
| Options | 3790978 | 3540570 |
| RSAs | 579660 | 579660 |
| Warrants | 225223 | 225223 |
| Total | 34117671 | 33867263 |

---

Under the organizational documents of the Company, the preferred shares are convertible by the holder at any time at their option. In addition, the preferred shares will automatically convert into common shares upon either (i) the determination of the holders of certain requisite preferred shares of the Company (which determination will be submitted for approval by such stockholders in connection with the Business Combination described in Note 1, *Description of the Business*), or (ii) a firmly underwritten initial public offering of the Company's shares that satisfies certain requirements (but not, for the avoidance of doubt, upon a business combination with a special purpose acquisition company, such as the Business Combination, unless such conversion is otherwise effected pursuant to clause (i) above). Such conversion would be at a 1:1 ratio, adjusted for certain corporate events. Upon conversion of the preferred shares, the cumulative accrued and declared dividends will become payable. The additional 29,521,810 of potential shares of common stock resulting from any such conversion are not included in the computation of diluted net loss per share in the nine months ended September 30, 2022 and 2021, respectively, because doing so would be anti-dilutive. In connection with the SAFE, see Note 6 - *Fair Value*, the Company could issue additional potential shares of common stock upon closing of the Business Combination. Further, under the Simple Agreement for Future Equity ("SAFE") warrant, additional potential shares of common stock could be issued upon closing of the Business Combination and exercise of the warrant. These potential shares of common stock have not been issued as of September 30, 2022. The per share issuance price for the SAFE and SAFE warrant upon closing of the Business Combination is 100% of the liquidity price. If another qualified liquidity event occurs instead, the issuance price is 90% of the liquidity price.

***Contract balances***

The following table provides changes in contract assets and liabilities (in thousands):

---

| | | | |
|:---|:---|:---|:---|
| | **Current Contract Assets** | **Current Contract Liabilities** | **Non-current Contract Liabilities** |
| Balance as of January 1, 2022 as Restated | $11700 | $3476 | $13901 |
| &nbsp;&nbsp;&nbsp;&nbsp;Additions to unbilled accounts receivable | 19355 |  |  |
| &nbsp;&nbsp;&nbsp;&nbsp;Increases due to cash received |  | 775 | 37 |
| &nbsp;&nbsp;&nbsp;&nbsp;Unbilled accounts receivable recognized in trade receivables | (16085) |  |  |

| &nbsp;&nbsp;&nbsp;&nbsp;Reclassification to revenue as a result of performance obligations satisfied |  | (3298) |  |
| Balance as of September 30, 2022 | $14848 | $2968 | $11119 |

---

The increase in contract assets was mostly due to unbilled accounts receivables from contracts with customers where the Company performed engineering and other services, while the decrease in contract liabilities was primarily due to the recognition of revenue during the period related to advance payments previously received by the Company for engineering and other services contracts with customers. As of September 30, 2022 and December 31, 2021 the Company had $11,588 and $2,878, respectively, of billed accounts receivable, net of allowance.

The contract liability balance is comprised of unconditional payments received from the Company's customers prior to the satisfaction of the related performance obligations. Such amounts are anticipated to be recorded as revenues when services are performed in subsequent periods. The Company expects to recognize the amounts classified as current contract liabilities, in revenue within one year or less and those classified as non-current within two to three years.

*Remaining performance obligations*

Transaction price allocated to the remaining performance obligation represents contracted revenue that has not yet been recognized, which includes unearned revenue that will be recognized as revenue in future periods. Transaction price allocated to remaining performance obligations is influenced by several factors, including the length of the contract term compared to the research term and the existence of customer specific acceptance rights.

***LanzaJet***

On May 13, 2020, the Company contributed $15,000 in intellectual property in exchange for a 37.5% interest ("Original Interest") of LanzaJet, Inc. ("LanzaJet") in connection with an investment agreement ("Investment Agreement"). The Company accounts for the transaction as a revenue transaction with a customer under ASC 606 *Revenue from Contracts with Customers*. The licensing and technical support services provided are recognized as a single combined performance obligation satisfied over the expected period of those services, beginning May 2020 through December 2025. During the nine months ended September 30, 2022 and 2021, the Company has recognized revenue from this arrangement of $1,620 and $1,516 respectively, net of intra-entity profit elimination. As of September 30, 2022 and December 31, 2021, the Company has recorded deferred revenue of $8,734 and $10,746, respectively. Intra-entity profits related to revenue contracts with LanzaJet are $395 and $497 as of September 30, 2022, and 2021, respectively. Intra-entity profit is amortized over the 15-year amortization period through 2034.

Between February 1, 2021 and April 4, 2021, LanzaJet closed two additional rounds of investment which reduced the Original Interest to 25%. As a result, the Company recognized a gain on dilution of $503. The Company retained its contingent right to receive an additional interest in LanzaJet of up to 45 million shares for no additional consideration.

The carrying value of our equity method investment in LanzaJet as of September 30, 2022 and December 31, 2021 was approximately $3,600 and $3,100 less than our proportionate share of our equity method investees' book values, respectively. The basis differences are largely the result of a difference in the timing of recognition of variable consideration to which we may become entitled in exchange for our contribution of intellectual property to LanzaJet. The variable consideration we may receive will be in the form of additional ownership interests and the majority of the basis difference will reverse in connection with recognition of that variable consideration.

In connection with a sublicense agreement to LanzaJet under our license agreement with Battelle Memorial Institute ("Battelle"), LanzaTech remains responsible for any failure by LanzaJet to pay royalties due to Battelle. The fair value of LanzaTech's obligation under this guarantee was immaterial as of September 30, 2022 and December 31, 2021.

------

***SGLT***

On September 28, 2011, the Company contributed RMB 25,800 (approx. $4,000) in intellectual property in exchange for 30% of the registered capital of Beijing ShouGang LanzaTech Technology Co., LTD ("SGLT").

As of December 31, 2021, the Company's interest in SGLT's registered capital is approximately 10.01%. As the result of the admittance of new investors, the Company recognized a gain from dilution of $3,014 during the nine months ended September 30, 2021. On April 29, 2022, SGLT closed a round of financing which reduced the Company's ownership to 9.31% and resulted in the recognition of gain from dilution of $3,368. On September 30, 2022, management of the Company determined that the Company no longer had significant influence over the operating and financial policies of SGLT due to the significant and sustained decrease in SGLT's technological dependence on LanzaTech. As such, as of September 30, 2022, the Company ceased applying the equity method and reclassified cumulative currency translation adjustments associated with its investment in SGLT of $928 to include those adjustments in the carrying value of its investment. Prospectively, the Company will account for its investment in the equity security of SGLT using the alternative measurement principals as permitted under ASC 321, *Investments - Equity Securities*, because SGLT's fair value is not readily determinable. As the change is effective on September 30, 2022, the Company recorded SGLT's attributable net loss of $76, for the nine months ended September 30, 2022, on the condensed consolidated statements of operations.

Subsequently, under the alternative measurement method, LanzaTech will adjust the carrying value for observable changes in price and will reassess whether its investment in SGLT continues to qualify for such method. Additionally, LanzaTech will perform a qualitative assessment and recognize an impairment if their are sufficient indicators that the fair value of the SGLT investment is less than its carrying value. The changes in value and impairment charges (if any), are recorded in other (expense) income, net in the condensed consolidated statement of operations.

As of September 30, 2022 and December 31, 2021, there were no impairments of either equity investees. During the nine months ended September 30, 2022 and the year ended December 31, 2021, the Company received no dividends from equity investments.

***Warrants***

The Company has warrants to purchase preferred shares outstanding as of September 30, 2022 and December 31, 2021 representing 225,223 and 225,223 preferred shares, respectively, which warrants expire at various dates through December 31, 2027. The exercise prices of the warrants range from $14.69 to $19.93 as of each of September 30, 2022 and December 31, 2021.

The warrants are accounted for as liabilities in accordance with ASC 480, *Distinguishing Liability from Equity*, and are presented within other accrued liabilities on the condensed consolidated balance sheets. The warrant liabilities are measured at fair value at inception and on a recurring basis, with changes in fair value presented within the condensed consolidated statements of operations and comprehensive loss.

The fair value of the warrants was calculated using the Black-Scholes Option Pricing Model. For the nine months ended September 30, 2022 and 2021, the Company recognized a change in the fair value of liabilities of approximately $(427) and $(699), respectively, on the condensed consolidated statements of operations and comprehensive loss within other (expense) income, net.

The estimated fair value of the warrants is determined using Level 3 inputs. Inherent in the Black-Scholes Option Pricing Model are assumptions related to expected stock-price volatility, expected life, risk-free interest rate and dividend yield. The Company estimates the volatility of its warrants based on implied volatility from the Company's warrants and from historical volatility of select peer companies that match the expected remaining life of the warrants. The risk-free interest rate is based on the U.S. Treasury zero-coupon yield curve on the grant date for a maturity similar to the expected remaining life of the warrants. The expected life of the warrants is assumed to be equivalent to their remaining contractual term. The dividend rate is based on the historical rate, which the Company anticipates remaining at zero.

The following table represents the weighted average inputs used in calculating the fair value of the preferred share warrants outstanding as of September 30, 2022 and December 31, 2021:

---

| | | |
|:---|:---|:---|
| | **September 30, 2022** | **December 31, 2021** |
| Stock price | $15.03 | $13.77 |
| Weighted average exercise price | 17.31 | 17.32 |
| Term (in years) | 2.3 | 2.8 |

***SAFE Liability and SAFE Warrant***

In December 2021, the Company issued a SAFE that allowed an investor to participate in future equity financings through a share-settled redemption of the amount invested (such notional being the "invested amount"). The SAFE had not yet converted as a qualifying financing had not yet occurred as of September 30, 2022. At September 30, 2022, the SAFE had a fair value of $27,221 and was recorded within current liabilities on the condensed consolidated balance sheet.

Further, the warrant related to the SAFE of $2,022 as of September 30, 2022 is accounted for as a liability. This liability is recorded in current liabilities on the Company's condensed consolidated balance sheets at fair value on the date of issuance and will be revalued each subsequent reporting period until such instrument is exercised or expires.

The change in fair value between reporting periods for both the SAFE liability and SAFE warrant is included in other (expense) income, net in the condensed consolidated statements of operations and comprehensive loss.

The Company's SAFE liability and SAFE warrant are mark-to-market liabilities pursuant to ASC 480 and are classified within Level 3 of the fair value hierarchy as the Company is using a scenario-based approach which allowed the Company to estimate the implied value of the business based on the terms of the SAFE. Significant unobservable inputs included probability and expected term. Probability is based upon the likelihood of the Company closing a transaction with a special purpose acquisition company. The expected term was based on the anticipated time until the SAFE investments would have a conversion event.

Significant inputs for Level 3 SAFE liability fair value measurement at September 30, 2022 are as follows:

---

|:---|:---|:---|
| | **Near Term** | **Long-Term** |
| Key assumptions: |  |  |

**Note 7 — Income Taxes**

The Company is subject to federal state income taxes in the United States, as well as income taxes in foreign jurisdictions in which it conducts business. The Company does not provide for federal income taxes on the undistributed earnings of its foreign subsidiaries as such earnings are reinvested indefinitely. The Company and its foreign subsidiaries have historically been loss generating entities that have resulted in no excess earnings to consider for repatriation and accordingly there are no deferred income taxes recognized for the nine months ended September 30, 2022 and 2021.

The Company recorded an income tax expense of $0 for the nine months ended September 30, 2022 and 2021, representing an effective tax rate of 0%. The difference between the U.S. federal statutory rate of 21% and the Company's effective tax rate in the first nine months ended September 30, 2022 is primarily due to a full valuation allowance related to the Company's U.S. deferred tax assets and tax benefits in the Company's foreign jurisdictions. For the first nine months ended September 30, 2021, the Company's effective tax rate was computed based on income tax rate in New Zealand of 28.0% as the Company was still domiciled in New Zealand. The Company reassesses the need for a valuation allowance on a quarterly basis. If it is determined that a portion or all of the valuation allowance is not required, it will generally be a benefit to the income tax provision in the period such determination is made.

The Company conducts business in multiple jurisdictions within and outside the United States. Consequently, the Company is subject to periodic income tax examinations by domestic and foreign income tax authorities. The Company is subject to audits for tax years 2009 and onward for federal purposes. There are tax years which remain subject to examination in various other state and foreign jurisdictions that are not material to the Company's financial statements.

During 2021, the Company migrated its country of domicile from New Zealand to Delaware in the United States. On migration, the Company was deemed to have disposed of all its assets and liabilities to a third-party at market value which resulted in taxable income to the Company for New Zealand income tax purposes which was fully offset by net operating loss carryforwards and deferred R&D credits in New Zealand. The migration to Delaware is classified as a tax-free reorganization for U.S. federal income tax purposes.

**Note 8 — Share-Based Compensation**

The Company offers share option plans to employees, directors, and others providing similar employee-related services, which meet the definition of an equity-settled share-based payment.

*Stock Options* 

The Company has five ownership-based participation rights schemes for employees, directors, and certain third-party providers. In accordance with the provisions of the schemes, as approved by the directors and shareholders, grantees have been granted options to purchase common shares at an exercise price based on the fair value price of the Company's common shares on the date of grant as approved by the directors. The stock options generally have a service condition of two to five years and vest over time as the service condition is being satisfied. Upon termination of employment, unvested stock options are evaluated for forfeiture or modifications, subject to the terms of the awards and Company's policies.

| Exercisable at September 30, 2022 | 2918 | $6.30 | 4.56 | $32874 |

---

The Company recorded compensation expense of $2,067 and $1,790 for the nine months ended September 30, 2022 and September 30, 2021, respectively. Unrecognized compensation costs as of September 30, 2022 was $3,835 and will be recognized over a weighted average of 2.27 years.

*Restricted Stock Awards ("RSAs")*

RSAs become eligible to vest upon the satisfaction of a time-based service condition. However, in order to vest, a liquidity event, defined as acquisition, asset transfer, or initial listing, must occur within 10 years from the grant date. Upon a liquidity event, if the participant's service has not terminated, the entire RSA award vests in full, whether or not previously eligible for vesting. If the participant's service has terminated and they have satisfied the time-based service condition, the RSAs that are outstanding and eligible for vesting shall immediately vest in full. The time-based service requirements of the RSAs have a maximum term of three years from the date of grant.

As of September 30, 2022, there were 579,660 outstanding unvested shares for a weighted average fair value of $4.72. There were no changes during the nine months ended September 30, 2022.

As of September 30, 2022, and September 30, 2021 the Company concluded that the liquidity event performance condition described above for the RSAs was not probable of being satisfied at such time. As a result, the Company did not recognize any compensation cost during the nine months ended September 30, 2022 and September 30, 2021 for any RSAs granted.

In connection with the formation of LanzaJet, the Company entered into a transition services agreement with LanzaJet. The transition services agreement generally sets out the respective rights, responsibilities and obligations of the Company and LanzaJet with respect to R&D services, access to office and laboratory space, business development and other administrative support services. The transition services agreement may be terminated by mutual consent of the Company and LanzaJet, by LanzaJet at any time, and by the Company upon breach or non-payment by LanzaJet. There are no substantive termination penalties in the event the Company terminates. For the nine months ended September 30, 2022 and September 30, 2021, the Company recognized revenue from related parties of approximately $148 and $355, respectively, under the transition services agreement. The Company also provides certain engineering and other services related to a gas-to-jet demonstration plant currently in development by LanzaJet pursuant to the Investment Agreement described in Note 5, *Investments*. In connection with these services, the Company recognized revenue from LanzaJet of approximately $170 and $403, for the nine months ended September 30, 2022 and September 30, 2021, respectively.

In May 2020, the Company executed an agreement to lease certain land to a subsidiary of LanzaJet for a period of 10 years with an option to renew this lease for five additional periods of one year with minimum annual rent due to the Company of $24. The lease commenced upon execution of the lease agreement and was subsequently amended in 2022 to extend the Pre-Development Term and annual rent amount. Refer to Note 12, *Leases*, for more information.

The Company supplies SGLT with certain water-soluble organic compounds required in the Company's proprietary gas fermentation process, and small-size equipment. As a result, for the nine months ended September 30, 2022 and September 30, 2021, the Company recognized revenue from related parties of approximately $151 and $69, respectively. The Company also provided engineering services and incurred costs of $$893 and $1,171 for the nine months ended September 30, 2022 and September 30, 2021, respectively.

Additionally, LanzaTech and SGLT entered into a license agreement in 2019, subsequently amended in 2021, to provide SGLT with the right to sublicense the intellectual property that LanzaTech previously licensed to SGLT. In exchange, the Company is entitled to receive licensing consideration, calculated as a percentage of the royalties received by SGLT from the sublicenses. Currently, SGLT sublicenses to certain of its subsidiaries that use LanzaTech's proprietary technology. The royalties received by SGLT are based on sales-and-usage of the sublicensed technology. For the nine months ended September 30, 2022, and September 30, 2021, the Company did not earn any sublicensing revenue as no royalties were received by SGLT.

---

| | | | | |
|:---|:---|:---|:---|:---|
| | **Shares Authorized** | **Shares<br>Issued and<br>Outstanding** | **Issue Price** | **Carrying<br>Amount** |
| Series A | 4666503 | 4666503 | $1.75 - 3.94 | $12230 |

|  | 29747033 | 29521810 |  | $480631 |

---

There were no changes in redeemable convertible preferred stock issued and outstanding during the nine months ended September 30, 2022. The holders of preferred shares are entitled to receive dividends on an as converted to common shares basis as if all preferred shares had been converted into common shares on the date of such event. Dividends are cumulative and are payable in arrears at the rate of 8% of the original issue price.

In March 2021, a warrant was exercised for a total issuance of 158,058 Series D preferred shares which led to an increase in redeemable convertible preferred stock of $3,150 during the nine months ended September 30, 2021.

Redemption features of preferred shares are not fixed and do not have a determinable price on fixed or determinable dates. As of September 30, 2022, the preferred shares are not currently redeemable, and it is not probable that the preferred shares will become redeemable, since it is uncertain whether or when circumstances exist that would constitute a deemed liquidation event. Accordingly, the Company has not adjusted the carrying value of the preferred shares to their redemption values.

**Note 11 — Commitments and Contingencies**

***Litigation***

The Company may be involved in legal proceedings and exposed to potential claims in the normal course of business. As of September 30, 2022 and December 31, 2021, the Company does not have any reasonable possible or probable losses from such claims.

**Note 12 — Leases** 

In May 2020, the Company executed an agreement to lease certain land to a subsidiary of LanzaJet for a period of 10 years with an option to renew this lease for five additional periods of one year with minimum annual rent due. This agreement is accounted for as an operating lease. In February 2022, the lease agreement with LanzaJet was amended to extend the pre-development term of the lease until the earlier of commencement of construction of the alcohol-to-jet fuel facility on the leased land or December 31, 2023 and increased the annual base rent amount. The Company recognizes lease revenue on a straight-line basis over the life of the lease agreement.

**Note 13 — Subsequent Events**

The Company has evaluated events occurring subsequent to September 30, 2022 through December 12, 2022, the date the condensed consolidated financial statements were available to be issued. The Company has identified two transactions with BGTF LT Aggregator LP ("Brookfield"), an affiliate of Brookfield Asset Management Inc, and a transaction with LanzaJet, described as follows:

***Brookfield Framework Agreement***

On October 2, 2022, LanzaTech entered into a framework agreement with Brookfield (the "Brookfield Framework Agreement"). Under such agreement, LanzaTech agreed to exclusively offer Brookfield the opportunity to acquire or invest in certain projects to construct commercial production facilities employing carbon capture and transformation technology in the U.S., the European Union, the United Kingdom, Canada or Mexico for which LanzaTech is solely or jointly responsible for obtaining or providing equity financing, subject to certain exceptions. LanzaTech agreed to present Brookfield with projects that over the term of the agreement require equity funding of at least $500,000,000 in the aggregate. With respect to projects acquired by Brookfield, LanzaTech is entitled to a percentage of free cash flow generated by such projects determined in accordance with a hurdle-based return waterfall. Brookfield has no obligation under the Brookfield Framework Agreement to invest in any of the projects.

***Brookfield SAFE***

On October 2, 2022, LanzaTech entered into a Simple Agreement for Future Equity (the "Brookfield SAFE") with Brookfield. Under the Brookfield SAFE, LanzaTech agreed to issue to Brookfield the right to certain shares of its capital stock, the issuance of which is conditional upon LanzaTech obtaining certain necessary stockholder approvals and waivers, in exchange for the payment of $50,000,000 (the "Initial Purchase Amount"). On the fifth anniversary of the Brookfield SAFE, LanzaTech will repay in cash any remaining unconverted portion of the Initial Purchase Amount (the "Remaining Amount") less any Non-Repayable Amount (as described below), plus interest in the high single digits, compounded annually. Brookfield has the option to extend the repayment date to the tenth anniversary of the date of the Brookfield SAFE if certain events do not occur.

Following the first of either (a) a transaction with the principal purpose of raising capital, pursuant to which LanzaTech issues and sells preferred stock at a fixed valuation (an "Equity Financing"), or (b) the completion of an initial public offering, a direct listing, or a merger of LanzaTech with a special purpose acquisition company, which includes the Business Combination (such a merger, a "de-SPAC Transaction" and such event described in (b), a "Liquidity Event"), Brookfield may, at any time at its option, convert all or a portion of the Initial Purchase Amount less any amount that has already been converted or repaid into shares of LanzaTech capital stock or, in the case of a de-SPAC Transaction, shares of common stock of the surviving public company in such de-SPAC Transaction (including, in the case of the Business Combination, New LanzaTech Common Stock).

For each $50,000,000 of aggregate equity funding required for qualifying projects acquired by Brookfield in accordance with the Brookfield Framework Agreement, the Remaining Amount will be reduced by $5,000,000 (such cumulative reductions the "Non-Repayable Amount"). Upon the first Equity Financing or Liquidity Event, the Non-Repayable Amount would convert automatically into shares of LanzaTech capital stock or, in the case of a de-SPAC Transaction, shares of common stock of the surviving public company in such de-SPAC Transaction (including, in the case of the Business Combination, New LanzaTech Common Stock), and thereafter, the Non-Repayable Amount will convert automatically on an as accrued basis.

***LanzaJet Shareholder Loan***

On November 9, 2022, the Company and the other LanzaJet shareholders entered into a Note Purchase Agreement (the "Note Purchase Agreement"), pursuant to which LanzaJet Freedom Pines Fuels LLC ("FPF"), a wholly owned subsidiary of LanzaJet, will issue, from time to time, notes in an aggregate principal amount of up to $147.0 million (the "Notes"), comprised of approximately $113.5 million aggregate principal amount of 6.00% Senior Secured Notes due December 31, 2043 and $33.5 million aggregate principal amount of 6.00% Subordinated Secured Notes due December 31, 2043. The Company has committed to purchase $5.5 million of Subordinated Secured Notes in a funding scheduled to occur on May 1, 2023. The Senior Secured Notes are secured by a security

------

interest over substantially all assets of FPF, and both the Senior Secured Notes and the Subordinated Secured Notes are secured by a security interest over all intellectual property owned or in-licensed by LanzaJet. LanzaJet also provides a guarantee of any costs and expenses required to complete the LanzaJet Freedom Pines Demonstration Facility and achieve commercial operation.

Each purchaser of Notes under the Note Purchase Agreement is also entitled to receive a warrant for the right to purchase 575 shares of common stock of LanzaJet for each $10,000 of Notes purchased by such purchaser (which, in the case of the Company, will be equal to a right to purchase 316,250 shares of common stock of LanzaJet).

The LanzaJet Note Purchase Agreement may be amended with the approval of holders of FPF and all holders of the LanzaJet Notes. Upon an event of default under the Note Purchase Agreement, each purchaser may accelerate its own Notes. Enforcement against the collateral securing the Notes requires the approval of certain holders as specified in the Notes.

***Amended Merger Agreement***

The Merger Agreement was amended on December 7, 2022, to provide for, among other things, (i) the inclusion of the aggregate net proceeds from each of the AM SAFE Note and Brookfield SAFE in the Acquiror Closing Cash Amount, (ii) the reduction of the Minimum Closing Cash Condition from $250,000,000 to $230,000,000, (iii) the clarification that, to the extent that the Brookfield SAFE remains unexercised at Closing, it will be assumed by AMCI, remain in effect on the same terms and conditions as are in effect prior to the Closing and thereafter entitle the holder thereof to be issued shares of common stock in AMCI after the Closing, (iv) the clarification that, in the event that it becomes reasonably apparent to the parties that the Acquiror Closing Cash Amount will be less than the Minimum Closing Cash Condition, AMCI will use commercially reasonable efforts to enter into non-redemption agreements, or similar agreements, as may be necessary to satisfy the Minimum Closing Cash Condition, (v) the extension of the outside date applicable to the Closing from December 7, 2022 to February 28, 2023 and (vi) the elimination of LanzaTech's right to terminate the agreement in the event that we fail to, on or prior to July 7, 2022, enter into one or more additional subscription agreements or non-redemption agreements as a result of which the sum of the PIPE Investment Amount (including net proceeds under the AM SAFE Note to LanzaTech) and the aggregate number of shares of Class A common stock subject to non-redemption agreements multiplied by $10.00, minus certain transaction expenses and other liabilities at Closing, would be equal to at least the Minimum Closing Cash Condition.

**REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM**

To the Shareholders and the Board of Directors of LanzaTech NZ, Inc.

**Opinion on the Financial Statements**

We have audited the accompanying consolidated balance sheets of LanzaTech NZ, Inc. and subsidiaries (the "Company") as of December 31, 2021 and 2020, the related consolidated statements of operations and comprehensive loss, consolidated statement of cash flows, and consolidated statements of changes in redeemable convertible preferred stock and shareholders' equity (deficit) for each of the two years in the period ended December 31, 2021, and the related notes (collectively referred to as the "financial statements"). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2021 and 2020, and the results of its operations and its cash flows for each of the two years in the period ended December 31, 2021, in conformity with accounting principles generally accepted in the United States of America.

**Material Restatement of the 2021 and 2020 Financial Statements**

As discussed in Note 2 to the financial statements, the accompanying 2021 and 2020 financial statements have been restated to correct material misstatements.

**Basis for Opinion**

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB and in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

**LANZATECH NZ, INC.**

**NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Restated)**

**Note 1 — Description of the Business**

The reporting entity is LanzaTech NZ, Inc. (formerly known as LanzaTech New Zealand Limited) and its subsidiaries (collectively, "the Company"). LanzaTech NZ, Inc. is a profit-oriented entity previously incorporated in New Zealand. Effective October 28, 2021, LanzaTech New Zealand Limited filed a Certificate of Incorporation to migrate its country of domicile from New Zealand to Delaware, in the United States, and change its corporate name to "LanzaTech NZ, Inc." The amendment was approved by the Board of Directors of LanzaTech and was effected by the filing of a Certificate of Incorporation with the Delaware Secretary of State. All necessary adjustments have been recorded to present fairly the Company's financial position as of December 31, 2021 and 2020 and the results of operations and cash flows for the years then ended. The registered office location is c/o The Corporation Trust Company, Corporation Trust Center, 1209 Orange Street, Wilmington, Delaware, 19801. The Company licenses its technology to customers, performs research and development in biotechnology, and provides engineering and other related services for commercial and government customers. Using the Company's proprietary fermentation technology, the Company's customers can convert certain carbon-rich waste gases into fuels and chemicals. The Company employs a licensing business model whereby its customers build, own and operate facilities that use the Company's technology, and in return, the Company is paid royalties based on the revenue generated from the use of its technology. In 2018, the Company, through its equity method investee, launched the world's first commercial waste gas to ethanol plant in China, followed by a second one in 2021, also in China, with others currently in development in various countries around the world.

**Note 2 — Summary of Significant Accounting Policies** 

***Basis of Presentation and Principles of Consolidation***

The consolidated financial statements were prepared in accordance with accounting principles generally accepted in the United States of America ("US GAAP"). The consolidated financial statements include the accounts of LanzaTech NZ, Inc. and its wholly-owned consolidated subsidiaries. All significant intercompany transactions and balances have been eliminated in consolidation.

As part of its evaluation, the Company makes judgments in determining whether an entity is a variable interest entity ("VIE") and, if so, whether it is the primary beneficiary of the VIE and is thus required to consolidate the entity. A VIE is a legal entity that has a total equity investment that is insufficient to finance its activities without additional subordinated financial support or whose equity investors lack the characteristics of a controlling financial interest. Our variable interest arises from contractual, ownership or other monetary interests in the entity, which change with fluctuations in the fair value of the entity's net assets. A VIE is consolidated by its primary beneficiary, the party that has both the power to direct the activities that most significantly impact the VIE's economic performance, and the obligation to absorb losses or the right to receive benefits of the VIE that could potentially be significant to the VIE. We consolidate a VIE when we are deemed to be the primary beneficiary. We assess whether or not we are the primary beneficiary of a VIE on an ongoing basis. If we are not deemed to be the primary beneficiary in a VIE, we account for the investment or other variable interests in a VIE in accordance with applicable US GAAP.

The Company holds interests in certain VIEs for which it has been determined the Company is not the primary beneficiary. The Company's variable interests primarily relate to entities in which the Company has a non-controlling equity interest. Although these financial arrangements resulted in holding variable interests in these entities, they did not empower the Company to direct the activities of the VIEs that most significantly impact the VIEs' economic performance. The Company's interests in the VIEs are, therefore, accounted for under the equity method of accounting. Refer to Note 5 - *Investments*, for further information. The Company's maximum exposure to loss in connection with its interest in VIEs is its equity method investment and any amounts receivable from the VIE, less amounts payable. Refer to Note 14, *Related Party Transactions*, for further details on the transactions with VIEs.

***Restatement***

On August 16, 2022, the Audit Committee of the Board of Directors of LanzaTech, after discussion with management of LanzaTech and LanzaTech's independent registered public accounting firm, Deloitte & Touche,

------

LLP, concluded that LanzaTech's previously issued audited consolidated financial statements as of and for the fiscal years ended December 31, 2021 and December 31, 2020 should no longer be relied upon. The errors leading to restatement were communicated to and discussed with AMCI upon their discovery. The AMCI Board considered the circumstances surrounding the restatement and concluded that it did not negatively impact its decision to proceed with the Business Combination primarily because of the individually immaterial adjustments.

The Company determined that its recorded share of equity method earnings amounts from an unconsolidated affiliate for the years ended December 31, 2021 and 2020 and its gain on dilution amount for the year ended December 31, 2021 were incorrect following the completion of LanzaJet, Inc's ("LanzaJet") financial statement audit. Additionally, the Company identified that it was not properly eliminating intra-entity profits related to revenue contracts with LanzaJet. As a result of the adjustments recorded by the unconsolidated affiliate and the identification of the error related to the elimination of intra-entity profits, the Company made the decision to restate its consolidated financial statements as of and for the years ended December 31, 2021 and 2020, on or around the completion of the audit of LanzaJet's financial statements for the years ended December 31, 2021 and 2020, on August 23, 2022. The Company also determined it was not properly accounting for its licensing arrangement with LanzaJet, and had not disclosed all significant related party transactions with its equity method investees. The Company has also revised these disclosures.

In accordance with ASC 250, *Accounting Changes and Error Corrections*, the Company evaluated the materiality of the adjustments, considering both quantitative and qualitative factors, and determined that the related aggregate impact was material to its consolidated financial statements as of and for the years ended December 31, 2021 and 2020.

Description of Errors Corrected

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*• Accounting for Equity Method Investments:* 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The previously reported equity method investment in LanzaJet, Inc. ("LanzaJet"), as described in Note 5 - *Investments*, contained errors in the Company's recorded share of LanzaJet losses for the years ended 2021 and 2020 as a result of adjustments made by LanzaJet to its financial statements in connection with the audit of LanzaJet's financial statements for the years ended December 31, 2021 and 2020. The adjustments primarily were comprised of (1) an adjustment to correct an error relating to the measurement of the intangible asset associated with the intellectual property contributed by the Company as described in Note 5 – *Investments* and the related amortization; and (2), an adjustment to reclassify as a reduction to fixed assets certain government grants received by LanzaJet that it originally recorded as revenue. Other less significant adjustments were also identified and corrected in connection with the audit of LanzaJet's financial statements for the years ended December 31, 2021 and 2020. The net impact of these adjustments on the equity method investment's balance and accumulated deficit in the Company's Consolidated Balance Sheets was a decrease of $580 and $257 as of December 31, 2021 and 2020, respectively. The net impact of these adjustments on the gain from equity method investees in the Company's Consolidated Statements of Operations and Comprehensive Loss was a decrease of $580 and $257 for the years ended December 31, 2021 and 2020, respectively.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The previously reported revenue from related parties related to contributed intellectual property contained errors for intra-entity profit that was not previously eliminated, as described in Note 5 - *Investments*. The impact of these errors on the equity method investment's balance and accumulated deficit in the Consolidated Balance Sheets was $662 and $549 as of December 31, 2021 and 2020, respectively and $662 and $549 on revenue from related party transactions in the Consolidated Statements of Operations and Comprehensive Loss for the years ended December 31, 2021 and 2020, respectively.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The previously reported gain on dilution, as described in Note 5 - *Investments*, was not correctly calculated for the year ended December 31, 2021. The impact of these errors on the equity method investment's balance and accumulated deficit in the Consolidated Balance Sheets as of December 31,

------

2021 was $322; and the impact on gain from equity method investees in the Consolidated Statements of Operations and Comprehensive Loss was $322 for the year ended December 31, 2021.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*• Additional Misstatements:*

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The previously reported contract assets and other accrued liabilities included revenue and related cost of revenue amounts that was recorded in an inappropriate period. These amounts were recorded in 2021, however, the performance obligation was actually satisfied in 2020.. The impact of these errors on the contract assets and other accrued liabilities in the Consolidated Balance Sheet as of December 31, 2020 was $122; and the impact on revenue from contracts with customers and cost of revenue from contracts with customers in the Consolidated Statements of Operations and Comprehensive Loss for the years ended December 31, 2021 and 2020 was $122.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*• Disclosure errors:*

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The Company determined its licensing arrangement with LanzaJet, described in Note 5 – Investments, should have been accounted for as a transaction with a customer solely within the scope of Accounting Standards Codification 606 - *Revenue from contracts with customers* ("ASC 606") rather than akin to an operating lease under Accounting Standards Codification 842, *Leases* ("ASC 842"). The licensing arrangement is a contract with our customer, LanzaJet, that conveys to LanzaJet the right to use an intangible asset (IP). Contracts with customers are accounted for under ASC 606 unless they are within the scope of other accounting literature. Because the licensing arrangement conveys the right to use an intangible asset, it is not within the scope of ASC 842. Under limited circumstances, ASC 606 requires certain arrangements that do not, in substance, transfer control of an asset (i.e., when the arrangement contains certain repurchase rights or obligations) to be accounted for as leases. However, those limited circumstances are not present in our licensing arrangement with LanzaJet. Therefore, the Company concluded accounting for the arrangement under ASC 606 is required. Because the period over which the Company determined it was required to recognize revenue under ASC 606 was the same as the period of time over which it had been recognizing revenue, there was no effect on the amounts recorded in the consolidated financial statements. Additionally, the difference in timing of recognition of the variable consideration resulted in a difference between the carrying value of our equity method investment in LanzaJet and our proportionate share LanzaJet's book values, that was not previously disclosed. However, the disclosures in Note 5 – *Investments*, have been revised accordingly.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The Company did not disclose in Note 5 – *Investments*, its obligation under a guarantee with sublicensing agreement between LanzaJet and a third party. The fair value of this guarantee was deemed immaterial as of December 31, 2021 and 2020.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The Company did not include in its disclosure for related party transactions in Note 14 - *Related Party Transactions*, that it also provided engineering services to one of its equity method investees, Beijing ShouGang LanzaTech Technology Co., LTD ("SGLT"), for which costs of $1,223 and $242 were incurred during the years ended December 31, 2021 and 2020. The Company also did not disclose that in 2019 it entered into a licensing agreement to receive licensing consideration from SGLT.

------

None of the errors discussed above were individually material to the financial statements, however, their cumulative impact was material and resulted in a restatement of the 2021 and 2020 financial statements. The effects of the correction of these errors on the relevant financial statement line items is as follows:

***Segment Information***

The Company operates as one operating segment. Operating segments are defined as components of an enterprise for which separate financial information is evaluated regularly by the chief operating decision maker ("CODM"), in deciding how to allocate resources and assess performance.

While the Company offers a variety of services and operates in multiple countries, the Company's business operates in one operating segment because most of the Company's service offerings are delivered and supported on a global basis, most of the Company's service offerings are deployed in a nearly identical way, and the Company's CODM evaluates the Company's financial information and resources and assesses the performance of these resources on a consolidated basis. There are no segment managers who are held accountable by the CODM, or anyone else, for operations, operating results, and planning for components below the consolidated level. Accordingly, the Company has determined that it has a single reportable and operating segment. See Note 4, *Revenues*, for disaggregation of the Company's revenues by customer location.

***Coronavirus (COVID-19)***

In March 2020, the World Health Organization declared the viral strain of coronavirus ("COVID-19") a global pandemic and recommended containment and mitigation measures worldwide. The spread of COVID-19 and the resulting economic contraction has resulted in increased business uncertainty. The consequences of a prolonged economic decline could include, but are not limited to, reduced revenues, increased instances of uncollectible customer receivables, and increased asset impairments in future periods. Accordingly, the Company cannot reasonably estimate the length or severity of this pandemic, or the extent to which the disruption may materially impact its consolidated balance sheets, consolidated statements of operations and comprehensive loss or statements of cash flows for future periods.

------

***Going Concern***

The accompanying consolidated financial statements of the Company have been prepared assuming the Company will continue as a going concern and in accordance with US GAAP. The going concern basis of presentation assumes that the Company will continue in operation one year after the date these financial statements are issued and will be able to realize its assets and discharge its liabilities and commitments in the normal course of business. The Company had cash and cash equivalents of $128,318 and an accumulated deficit of $379,889 at December 31, 2021 and cash outflows from operations of $42,591 and a net loss of $46,689 for the year ended December 31, 2021.

The Company has historically funded its operations through debt financing and issuance of equity securities. Based on the Company's financial position as of the date these consolidated financial statements were issued, the Company projects that it will be able to cover its liquidity needs for the next twelve months with cash on hand. Accordingly, the Company's consolidated financial statements have been prepared on the basis that it will continue as a going concern.

***Use of Estimates***

The preparation of financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the consolidated financial statements, and the reported amounts of revenues and expenses during the reporting period. Significant estimates include fair value of equity awards granted to both employees and non-employees.

Changes in facts and circumstances or additional information may result in revised estimates, and actual results may differ from these estimates.

***Foreign Currencies***

The Company's reporting currency is the U.S. Dollar. The Company has certain foreign subsidiaries where the functional currency is the local currency. All of the assets and liabilities of these subsidiaries are converted to U.S. dollars at the exchange rate in effect at the balance sheet date, income and expense accounts are translated at average rates for the period, and shareholder's equity accounts are translated at historical rates. The effects of translating financial statements of foreign operations into our reporting currency are recognized as an adjustment in accumulated other comprehensive income (loss).

The Company also has foreign subsidiaries that have a functional currency of the U.S. dollar. Purchases and sales of assets and income and expense items denominated in foreign currencies are remeasured into U.S. dollar amounts on the respective dates of such transactions. Net realized foreign currency gains or losses relating to the differences between these recorded amounts and the U.S. dollar equivalent actually received or paid are included within Other income, net in the consolidated statements of operations and comprehensive loss.

***Cash, Cash Equivalents, and Restricted Cash***

The Company considers all highly liquid investments with an original maturity of three months or less at the time of purchase to be cash equivalents. As of December 31, 2021 and 2020, the Company had $128,318 and $60,495 of cash and cash equivalents, respectively.

The Company is required to maintain a cash deposit with a bank which consists of collateral on a travel and expense program maintained by the bank. The following represents a reconciliation of cash and cash equivalents in

***Trade and Other Receivables***

Receivables are reported net of allowances for doubtful accounts. The Company maintains allowances for doubtful accounts for estimated losses resulting from the inability of customers to make required payments. The Company estimates the allowance for doubtful accounts based on a variety of factors including the length of time receivables are past due, the financial health of customers, unusual macroeconomic conditions, and historical experience. As of December 31, 2021 and 2020, the Company recognized an allowance for doubtful accounts of $1,235 and $1,325, respectively.

***Other Current Assets***

Other current assets consist of prepaid expenses, materials and supplies, and other assets. Material and supplies consist of spare parts and consumables used for research and research equipment and is stated at the weighted average cost.

***Property, Plant and Equipment, net***

Property and equipment are stated at cost and include improvements that significantly increase capacities or extend the useful lives of existing plant and equipment. Depreciation is calculated using the straight-line method over the estimated useful life of the assets. Useful lives range from three to five years for instruments and equipment, three to five years for office equipment and furniture and software, five years for vehicles and, for leasehold improvements, the shorter of the life of the improvement or the remaining term of the lease.

The Company reviews the remaining useful life of its assets on a regular basis to determine whether changes have taken place that would suggest that a change to depreciation policies is warranted.

Upon retirement or disposal of property, plant and equipment, the cost and related accumulated depreciation are removed from the account, and the resulting gains or losses, if any, are recorded in the consolidated statements of operations and comprehensive loss. Net gains or losses related to asset dispositions are recognized in earnings in the period in which dispositions occur. Routine maintenance, repairs and replacements are expensed as incurred.

***Leases***

The Company determines if an arrangement is a lease at inception. Lease agreements are evaluated to classify the lease as a finance or operating lease. Operating lease assets and liabilities are recognized at the commencement date of the lease based on the present value of lease payments over the lease term. Lease assets represent the Company's right to use an underlying asset for the lease term and lease liabilities represent the Company's obligation to make lease payments arising from the lease. As most leases do not provide an implicit interest rate, the Company uses its incremental borrowing rate based on the information available at the lease commencement date in determining the present value of lease payments. Leases with an initial term of 12 months or less are not recorded on the Company's consolidated balance sheets. The Company recognizes lease expense for these leases on a straight-line basis over the lease term. The Company accounts for lease components and non-lease components as a single lease component.

------

***Impairment of Long-Lived Assets***

The Company performs a recoverability assessment of each of its long-lived assets whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Indicators may include, but are not limited to, adverse changes in the regulatory environment in a jurisdiction where the Company operates, a decision to discontinue the development of a long-lived asset, early termination of a significant customer contract, or the introduction of newer technology.

When performing a recoverability assessment, the Company measures whether the estimated future undiscounted net cash flows expected to be generated by the asset exceeds its carrying value. In the event that an asset does not meet the recoverability test, the carrying value of the asset will be adjusted to fair value resulting in an impairment charge.

Management develops the assumptions used in the recoverability assessment based on active contracts as well as information received from third-party industry sources. The Company did not record an impairment during the years ended December 31, 2021 and 2020.

***Equity Method Investments***

Investments in entities over which the Company has significant influence, but not control, are accounted for using the equity method of accounting. Gain from equity method investees, net represents the Company's proportionate share of net income or loss of its equity method investees and any gains or losses from the dilution of such investments.

Equity method investments are assessed for impairment whenever changes in the facts and circumstances indicate a loss in value may have occurred. When a loss is deemed to have occurred and is other than temporary, the carrying value of the equity method investment is written down to fair value. In evaluating whether a loss is other than temporary, the Company considers the length of time for which the conditions have existed and its intent and ability to hold the investment.

***Simple Agreement for Future Equity (SAFE)***

In December 2021, the Company issued a SAFE that allowed an investor to participate in future equity financings through a share-settled redemption of the amount invested (such notional being the "invested amount"). The Company determined that the SAFE was not legal form debt (i.e., no creditors' rights). The SAFE includes a provision allowing for cash redemption upon the occurrence of a change of control, the occurrence of which is outside the control of the Company. Therefore, the SAFE is classified as mark-to-market liability pursuant to Accounting Standards Codification ("ASC") 480, *Distinguishing Liability from Equity*.

***Warrants***

The Company has warrants to purchase preferred shares outstanding as of December 31, 2021 and 2020 representing 225,223 and 383,281 preferred shares, respectively, which warrants expire at various dates through December 31, 2027. The exercise prices of the warrants range from $14.69 to $19.93 as of each of December 31, 2021 and 2020. The Company accounts for its warrants as liabilities based upon the characteristics and provisions of each instrument. The liabilities are included in other accrued liabilities on the Company's consolidated balance sheets at their fair value on the date of issuance and are revalued in each subsequent reporting period until such instruments are exercised or expire. The change in fair value between reporting periods is included in other (expense) income, net in the consolidated statements of operations and comprehensive loss.

Further the warrant related to the SAFE of $1,729 is accounted for as a liability. This liability is recorded in current liabilities on the Company's consolidated balance sheets at fair value on the date of issuance and will be revalued each subsequent reporting period until such instrument is exercised or expire. The change in fair value between reporting periods is included in other (expense) income, net in the consolidated statements of operations and comprehensive loss.

------

***Long-Term Debt and Debt Issuance Costs***

The Company's debt consists of credit facilities with financial institutions. Costs directly related to the issuance of debt are reported on the consolidated balance sheets as a reduction from the carrying amount of the recognized debt liability and amortized over the term of the debt using the effective interest method.

***Legal and Contingencies***

The Company may be involved in legal actions in the ordinary course of business, inquiries and proceedings concerning employment, labor, environmental, and other claims. The Company will recognize a loss contingency in the consolidated financial statements when it is probable a liability has been incurred and the amount of the loss can be reasonably estimated. The Company will disclose any loss contingencies that do not meet both conditions if there is a reasonable possibility that a loss may have been incurred. Gain contingencies are not recorded until realized.

***Revenue Recognition***

The Company recognizes revenue in accordance with ASC 606, *Revenue from Contracts with Customers*. The Company primarily earns revenue from services related to feasibility studies and basic engineering design of commercial plants, licensing of technologies, joint development and contract research activities to develop novel biocatalysts and related technologies.

Revenue is measured based on the consideration specified in a contract with a customer. The Company records taxes collected from customers and remitted to governmental authorities on a net basis. The Company's payment terms are between 30-60 days and can vary by customer type and products offered. We have evaluated the terms of our arrangements and determined that they do not contain significant financing components.

*Carbon Capture and Transformation*

The Company provides feasibility studies and basic design and engineering services used for detailed design, procurement, and construction of commercial plants that utilize the Company's technologies, along with the sale of equipment and microbes. The services provided are recognized as a performance obligation satisfied over time. Revenue is recognized using the output method based on milestone completion, the cost-to-cost input method for certain engineering services, or the percentage of completion method when certain revenue recognition requirements are met. Management has determined that the milestone completion and the associated contractual payment amounts are an appropriate measure of progress towards complete satisfaction of the performance obligations under ASC 606.

The Company licenses intellectual property to generate recurring revenue when its customers deploy carbon capture and transformation plants. When licenses are considered to be distinct performance obligations, the recognition of revenue is dependent on the terms of the contract, which may include fixed consideration or royalties based on sales or usage, in which case, the revenue is recognized when the subsequent sale or usage occurs or when the performance obligation to which some or all of the sales or usage-based royalty is allocated has been satisfied, whichever is later.

*Research and Development Services*

The Company performs research and development ("R&D") services related to novel technologies and development of biocatalysts for commercial applications, mainly to produce fuels and chemicals. The Company engages in two main types of R&D services – joint development agreements, and other contract research, including projects with the U.S. Department of Energy. Such services are recognized as a performance obligation satisfied over time. Revenue is recognized based on milestone completion, when such milestones are contractually defined, or based on stage of contract completion when not defined. For the latter, management has determined that the cost incurred, input method, is an appropriate measure of progress towards complete satisfaction of the performance obligations under ASC 606, *Revenue from Contracts with Customers,* and estimates its variable consideration under the expected value method. Accordingly, the Company records a liability based on milestones achieved and the expected repayment of the development costs.

------

The Company's joint development agreements may utilize the cost-to-cost method of revenue recognition or may include well defined payment milestones, dependent on the contract, both of which the Company evaluates against work completed prior to revenue recognition. For other contract research, the Company utilizes the cost-to-cost method of revenue recognition. These contracts have a fixed dollar amount which is based on the Company's estimate of total costs to be incurred over the life of each contract.

Revenue is not recognized in advance of customer acceptance of a milestone, when such acceptance is contractually required. Payments for R&D services with no contractual payments are not due from customers until a technical report is submitted; therefore, a contract asset is recognized at milestone completion but prior to the submission of a technical report. The contract asset represents the Company's right to consideration for the services performed at milestone completion. Occasionally, customers provide payments in advance of the Company providing services which creates a contract liability for the Company. The contract liability represents the Company's obligation to provide services to a customer.

***Collaboration Arrangements***

The Company has certain partnership agreements that are within the scope of ASC 808, *Collaborative Arrangements*, which provides guidance on the presentation and disclosure of collaborative arrangements. Generally, the classification of the transactions under the collaborative arrangements is determined based on the nature of the contractual terms of the arrangement, along with the nature of the operations of the participants. The Company's collaborative agreements generally include a provision of R&D services related to novel technologies and biocatalysts. Amounts received for these services are classified as Revenue from collaborative arrangements in the consolidated statements of operations and comprehensive loss. The Company's R&D services are a major part of the Company's ongoing operations and therefore ASC 606 is applied to recognize revenue.

***Cost of Revenues***

The Company's R&D, engineering, and other direct costs of services related to revenue agreements with customers, related parties, and collaborative partners represent cost of revenue. Costs include both internal and third-party fixed and variable costs and include materials, supplies, labor, and fringe benefits.

***Research and Development***

We incur research and development costs associated with various R&D activities and expense these costs as incurred.

***Stock-Based Compensation***

The Company accounts for equity-based compensation in accordance with ASC 718, *Compensation – Stock Compensation*. Accordingly, in exchange for employee and director services, compensation is given in the form of equity awards. The equity awards are recorded based on the grant date fair value and expensed over the requisite service period for the respective award.

The Company's equity-based awards include stock option awards and restricted stock issued by the Company, which vest based on either time or the achievement of certain performance conditions. The Company records forfeitures as they occur. Compensation expense resulting from time-vesting-based awards is recognized in the Company's consolidated statements of operations and comprehensive loss, primarily within research and development expenses, at the grant date fair value over the requisite service period. Compensation expense resulting from performance awards recognized over the requisite service period when it is probable that the performance condition will be met. The calculated compensation expense for performance awards is adjusted based on an estimate of awards ultimately expected to vest. The Company estimates grant date fair value using a Black-Scholes option pricing model that uses assumptions including expected volatility, expected term, and the expected risk-free rate of return. The Company has determined that the Black-Scholes option pricing model, as well as the underlying assumptions used in its application, is appropriate in estimating the fair value of its award grants.

------

***Income Taxes***

The Company follows the asset and liability method of accounting for income taxes under ASC 740, Income Taxes. Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to temporary differences between the financial statements carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that included the enactment date. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount expected to be realized.

Deferred income tax assets are evaluated to determine if valuation allowances are required or should be adjusted. Valuation allowances are established based on a more likely than not standard. The ability to realize deferred tax assets depends on the Company's ability to generate sufficient taxable income within the carryback or carryforward periods provided for in the tax law for each tax jurisdiction. The Company considers the various possible sources of taxable income when assessing the realization of its deferred tax assets. The valuation allowances recorded against deferred tax assets generated by taxable losses in certain jurisdictions will affect the provision for income taxes until the valuation allowances are released. The Company's provision for income taxes will include no tax benefit for losses incurred and no tax expense with respect to income generated in these jurisdictions until the respective valuation allowance is eliminated.

The Company records uncertain tax positions on the basis of a two-step process whereby it is determined whether it is more likely than not that the tax positions will be sustained based on the technical merits of the position, and for those tax positions that meet the more likely than not criteria, the largest amount of tax benefit that is greater than 50% likely to be realized upon ultimate settlement with the related tax authority is recognized. The Company recognizes accrued interest and penalties related to unrecognized tax benefits in income tax expense.

***Related Party Transactions***

The Company follows ASC 850-10, *Related Party Transactions*, for the identification of related parties and disclosure of related party transactions.

Pursuant to ASC 850-10-20, related parties include: a) affiliates of the Company; b) entities for which investments in their equity securities would be required, absent the election of the fair value option under the Fair Value Option Subsection of Section 825-10-15, to be accounted for by the equity method by the investing entity; c) trusts for the benefit of employees, such as pension and profit-sharing trusts that are managed by or under the trusteeship of management; d) principal owners of the Company; e) management of the Company; f) other parties with which the Company may deal if one party controls or can significantly influence the management or operating policies of the other to an extent that one of the transacting parties might be prevented from fully pursuing its own separate interests; and g) other parties that can significantly influence the management or operating policies of the transacting parties or that have an ownership interest in one of the transacting parties and can significantly influence the other to an extent that one or more of the transacting parties might be prevented from fully pursuing its own separate interests. Refer to Note 5 - *Investments*, and Note 14, *Related Party Transactions*, for further information.

***Net Loss Per Share***

Basic net loss per share is computed by dividing net loss attributable to participating stock by the weighted average number of shares of participating stock outstanding during the period.

Diluted net loss per share reflects potential dilution and is computed by dividing net loss attributable to participating stock by the weighted average number of shares of participating stock outstanding during the period. The dilutive effect of outstanding awards, if any, is reflected in diluted earnings per share by application of the treasury stock method or if-converted method, as applicable. Refer to Note 3, *Net Loss Per Share*, for additional information.

------

***Fair Value of Financial Instruments***

Fair value is defined as the exchange price that would be received for an asset or an exit price paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The fair value hierarchy defines a three-level valuation hierarchy for disclosure of fair value measurements as follows:

**Level 1** — Valuations based on quoted prices in active markets for identical assets or liabilities that an entity has the ability to access;

**Level 2** — Valuations based on quoted prices for similar assets or liabilities, quoted prices for identical assets or liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable data for substantially the full term of the assets or liabilities; and

**Level 3** — Valuations based on inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

The categorization of a financial instrument within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement.

The fair value of the Company's assets and liabilities, which qualify as financial instruments under ASC Topic 820, *Fair Value Measurement*, approximates the carrying amounts represented in the accompanying consolidated balance sheets, primarily due to their short-term nature, except for the warrant liability. Refer to Note 11, *Warrant Liabilities*, for more information.

***Concentration of Credit Risk and Other Risks and Uncertainties (Restated)***

Revenue generated from the Company's customers outside of the United States for the years ended December 31, 2021 and 2020 was approximately 38% and 14%, respectively.

As of December 31, 2021 and 2020, approximately 35% and 27%, respectively, of trade accounts receivable and unbilled accounts receivable was due from customers located outside the United States. At December 31, 2021 and 2020, the value of property, plant, and equipment outside the United States was immaterial.

The Company's revenue by geographic region based on the customer's location is presented in Note 4, *Revenues*.

*Customers*

Customers representing 10% or greater of revenue were as follows for the years ended December 31, 2021 and 2020:

---

| | | |
|:---|:---|:---|
| | **Year Ended December 31,** | **Year Ended December 31,** |
| | **2021**<br>**as Restated** | **2020**<br>**as Restated** |
| Customer A | 27% | 28% |
| Customer B | 15% | 27% |
| Customer C | 12% | 22% |

---

As of December 31, 2021, two of the Company's customers separately represented 49% (Customer B) and 15% (Customer D) of total accounts receivable and contract assets on the consolidated balance sheet.

***Recently Adopted Accounting Pronouncements***

In June 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2016-13, *Financial Instruments – Credit Losses (Topic 326): Disclosure Framework – Measurement of Credit Losses on Financial Instruments* ("ASU 2016-13"), which requires financial assets measured at amortized cost basis, including trade receivables, to be presented net of the amount expected to be collected. The measurement of all expected credit losses will be based on historical experience, current conditions, and reasonable and supportable forecasts. The Company adopted the new standard effective January 1, 2020, using a modified retrospective transition method, which requires a cumulative-effect adjustment, if any, to the opening balance of retained earnings to be recognized on the date of adoption with prior periods not restated. The adoption did not have a material impact on the Company's financial position or results of operations.

In August 2018, the FASB issued ASU 2018-15, *Intangibles – Goodwill and Other – Internal-Use Software (Subtopic 350-40): Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract* ("ASU 2018-15"), which requires a customer in a cloud computing arrangement that is a service contract to follow the internal-use software guidance in ASC 350-40 to determine which implementation costs to capitalize as assets. A customer's accounting for the costs of the hosting component of the arrangement is not affected by the new guidance. The Company adopted ASU 2018-15 as of January 1, 2020 with no material impact on its consolidated financial statements.

In September 2018, the FASB issued ASU 2018-07, *Compensation - Stock Compensation Improvements to Non-employee Share-Based Payment Accounting* ("ASU 2018-07"), which simplifies the accounting for stock-based payments granted to non-employees for goods and services. Under ASU 2018-07, most of the guidance on such payments to non-employees will be aligned with the requirements for stock-based payments granted to employees. The Company early adopted ASU 2018-07 as of January 1, 2020 and its adoption did not have a material impact on the Company's consolidated financial statements.

In December 2019, the FASB issued ASU 2019-12, *Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes* ("ASU 2019-12"), as part of its simplification initiative to reduce the cost and complexity in accounting for income taxes. ASU 2019-12 removes certain exceptions related to the approach for intra-period tax allocation, the methodology for calculating income taxes in an interim period and the recognition of deferred tax liabilities for outside basis differences. ASU 2019-12 also amends other aspects of the guidance to help simplify and promote consistent application of US GAAP. The Company adopted ASU 2019-12 as of January 1, 2021 with no material impact on its consolidated financial statements.

***Recently Announced Accounting Pronouncements***

In October 2020, the FASB issued ASU No. 2020-10, *Codification Improvements* ("ASU 2020-10"). The standard contains improvements to the FASB Accounting Standards Codification (the "Codification") by ensuring that all guidance that requires or provides an option for an entity to provide information in the notes to financial statements is codified in the disclosure section of the Codification. The standard also improves various topics in the Codification so that entities can apply guidance more consistently on codifications that are varied in nature where the original guidance may have been unclear. The amendments in ASU 2020-10 are effective for the Company for fiscal years beginning after December 15, 2021, and interim periods within fiscal years beginning after December 15, 2022. Early adoption is permitted. The Company does not expect the adoption of ASU 2020-10 to have a material impact on its consolidated financial statements and related disclosures.

**Note 3 — Net Loss Per Share**

Basic net loss per share is computed by dividing net loss by the weighted-average number of shares of common stock of the Company outstanding during the period. Diluted net loss per share is computed by giving effect to all potential shares of common stock of the Company, including outstanding stock options, warrants, and contingently redeemable preferred stock, to the extent dilutive.

------

The following table presents the calculation of basic and diluted net loss per share for the Company's common stock (in thousands, except shares and per share amounts):

__________________

(1)In periods in which the Company reports a net loss, all stock-based compensation awards are excluded from the calculation of diluted weighted average shares outstanding because of their anti-dilutive effect on earnings (loss) per share.

As of December 31, 2021 and 2020, potential shares of common stock not included in the computation of earnings per share because their effect would be antidilutive include the following:

---

| | | |
|:---|:---|:---|
| | **Year Ended December 31,** | **Year Ended December 31,** |
| | **2021** | **2020** |
| Redeemable convertible preferred stock (if converted) | 29521810 | 25729542 |
| Options | 3848420 | 4283200 |
| RSAs | 579660 | 324680 |
| Warrants | 225223 | 383281 |
| Total | 34175113 | 30720703 |

---

Under the organizational documents of the Company, the preferred shares will automatically convert into common shares upon either (i) the determination of the holders of certain requisite preferred shares of the Company (which determination will be submitted for approval by such stockholders in connection with the Merger described below in Note 20) or (ii) a firmly underwritten initial public offering of the Company's shares that satisfies certain requirements (but not, for the avoidance of doubt, upon a business combination with a special purpose acquisition company, such as the Merger, unless such conversion is otherwise effected pursuant to clause (i) above). Such conversion would be at a 1:1 ratio, adjusted for certain corporate events.Upon conversion of the preferred shares, the cumulative accrued and declared dividends will become payable. The additional 29,521,810 and 25,729,542 of potential shares of common stock resulting from any such conversion are not included in the computation of diluted net loss per share in 2021 and 2020, respectively, because neither an initial public offering nor a stockholder determination of such conversion had occurred at the end of the period. In connection with the SAFE, see Note 10 - *Simple Agreement for Future Equity*, the Company could issue additional potential shares of common stock upon closing of the Merger. Further, under the SAFE warrant, see Note 6 – *Fair Value* and Note 11 – *Warrants Liability*, additional potential shares of common stock could be issued upon closing of the Merger and exercise of the warrant. These potential shares of common stock have not been issued as of December 31, 2021. The per share issuance price for the SAFE and SAFE warrant upon closing of the Merger is 100% of the liquidity price. If another qualified liquidity event occurs instead, the issuance price is 90% of the liquidity price.

The increase in contract assets was mostly due to unbilled accounts receivables from contracts with customers where the Company performed engineering and other services, while the increase in contract liabilities was primarily due to advance payments received under engineering and other services. As of December 31, 2021 and 2020 the Company had $2,878 and $5,521, respectively, of billed accounts receivable.

The contract liability balance is comprised of unconditional payments received from the Company's customers prior to the satisfaction of the related performance obligations. Such amounts are anticipated to be recorded as revenues when services are performed in subsequent periods. The Company expects to recognize the amounts classified as current contract liabilities, in revenue within one year or less and those classified as non-current within two and three years.

*Remaining performance obligations*

Transaction price allocated to the remaining performance obligation represents contracted revenue that has not yet been recognized, which includes unearned revenue that will be recognized as revenue in future periods. Transaction price allocated to remaining performance obligations is influenced by several factors, including the length of the contract term compared to the research term and the existence of customer specific acceptance rights.

Remaining performance obligations consisted of the following (in thousands):

**Equity Method Investments**

***LanzaJet***

On May 13, 2020, the Company contributed $15,000 in intellectual property in exchange for a 37.5% interest ("Original Interest") of LanzaJet, Inc. ("LanzaJet") and the right to future increase in ownership whereby LanzaTech could become a majority owner of LanzaJet if the intellectual property is used commercially in connection with an investment agreement ("Investment Agreement"). The Company also agreed to perform certain technical and administrative support services. LanzaJet is a sustainable fuels technology company dedicated to expanding sustainable aviation fuels ("SAF") to reduce greenhouse gas emissions and the decarbonization of the aviation and transportation industries. LanzaJet's access to the license is in perpetuity if certain key performance indicators ("KPI's") are met in accordance with the Investment Agreement. If these KPI's are not met by December 31, 2025, the Company may terminate the license. The Company accounts for the transaction in accordance with ASC 606. The licensing and support services provided are recognized as a performance obligation satisfied over the expected period of those services, beginning May 2020 through December 2025. During the years ended December 31, 2021

------

and 2020, the Company has recognized revenue from this arrangement of $2,025 and $1,018 and has recorded deferred revenue of $10,746 and $13,433 respectively. Further, the Company has eliminated intra-entity profits related to revenue contracts with LanzaJet of $662 and $549 as of December 31, 2021, and 2020, respectively. Intra-entity profit is amortized over the 15-year amortization period through 2034.

In addition to the Original Interest, the Investment Agreement allows at the option of the other investors party thereto to contribute additional funds towards building commercial plants and to receive a technology sublicense if certain KPI's are met. At such point, the Company would receive an additional interest in LanzaJet of up to 45 million shares for no additional consideration at that time. There would be no additional LanzaJet Board of Director representation with the potential increased interest. The additional tranches of interests in LanzaJet received upon the achievement of certain KPIs represent non-monetary variable consideration. The Company has applied the variable consideration constraint per ASC 606 and recognized no variable consideration as of December 31, 2021 as the Company has determined that it is not probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved. The Company regularly reviews and updates its estimates. Any changes made are recorded as a cumulative adjustment in the period identified and revenue for future periods is recognized using the new adjusted estimate.

Between February 1, and April 4, 2021, LanzaJet closed two additional rounds of investment which reduced the Company's Original Interest to 25%. As a result, the Company recognized a gain on dilution of $503. The Company retained its right to receive additional interest in LanzaJet of up to 45 million shares for no additional consideration.

The carrying value of our equity method investments as of December 31, 2021 and 2020 was approximately $3,100 and $3,800 less than our proportionate share of our equity method investees' book values, respectively. The basis differences relate primarily to our equity method investment in LanzaJet and are largely the result of a difference in the timing of recognition of variable consideration to which we may become entitled in exchange for our contribution of IP to LanzaJet. The variable consideration we may receive will be in the form of additional ownership interests and the majority of the basis difference will reverse in connection with recognition of that variable consideration.

In connection with a sublicense agreement to LanzaJet under our license agreement with Battelle Memorial Institute ("Battelle"), LanzaTech remains responsible for any failure by LanzaJet to pay royalties due to Battelle. The fair value of LanzaTech's obligation under this guarantee was immaterial as of December 31, 2021 and 2020.

***SGLT***

On September 28, 2011, the Company contributed RMB 25,800 (approx. $4,000) in intellectual property in exchange for 30% of the registered capital of SGLT. SGLT utilizes and develops technologies and know-how in connection with the production of anhydrous ethanol from steel mill waste gases. The contribution was recognized as revenue in 2011.

As of December 31, 2021 and 2020, as the result of the admittance of new investors, the Company's interest in SGLT's registered capital is approximately 10.01% and 11.14%, respectively. The Company recognized a gain from the dilution of $3,048 and $3,811 during the years ended December 31, 2021 and December 31, 2020, respectively. The Company has continued to apply the equity method of accounting to the investment as the Company maintains significant influence via representation on SGLT's Board of Directors and SGLT's significant dependency on the intellectual property the Company contributed.

The warrants are accounted for as liabilities in accordance with ASC 480 and are presented within other accrued liabilities on the consolidated balance sheets. The warrant liabilities are measured at fair value at inception and on a recurring basis, with changes in fair value presented within the consolidated statements of operations and comprehensive loss.

The fair value of the warrants was calculated using the Black-Scholes Option Pricing Model. For the years ended December 31, 2021 and 2020, the Company recognized a change in the fair value of liabilities of approximately $(563) and $105, respectively, on the statements of operations and comprehensive loss within other income (expense), net.

The estimated fair value of the warrants is determined using Level 3 inputs. Inherent in the Black-Scholes Option Pricing Model are assumptions related to expected stock-price volatility, expected life, risk-free interest rate and dividend yield. The Company estimates the volatility of its warrants based on implied volatility from the Company's warrants and from historical volatility of select peer companies that match the expected remaining life of the warrants. The risk-free interest rate is based on the U.S. Treasury zero-coupon yield curve on the grant date for a maturity similar to the expected remaining life of the warrants. The expected life of the warrants is assumed to be equivalent to their remaining contractual term. The dividend rate is based on the historical rate, which the Company anticipates remaining at zero.

The following table represents the weighted average inputs used in calculating the fair value of the preferred share warrants outstanding as of December 31, 2021 and 2020:

---

| | | |
|:---|:---|:---|
| | **2021** | **2020** |
| Stock price | $13.77 | $4.68 |

The Company's SAFE liability and SAFE warrant are mark-to-market liabilities pursuant to ASC 480 and are classified within Level 3 of the fair value hierarchy as the Company is using a scenario-based approach which allowed the Company to estimate the implied value of the business based on the terms of the SAFE. Significant unobservable inputs included probability and expected term. Probability is based upon the likelihood of the Company closing a transaction with a special purpose acquisition company. The expected term was based on the anticipated time until the SAFE investments would have a conversion event.

Significant inputs for Level 3 SAFE liability fair value measurement at December 31, 2021 are as follows:

In 2016, a loan facility was entered into with Venture Lending and Leasing VII, Inc. and Venture Lending and Leasing VIII, Inc. (the "2016 WTI Loan") for a total of $17,500 available in three tranches, all of which have been drawn. Tranches one and two were fully repaid as of December 31, 2020. The coupon interest rate for each tranche is the WSJ prime rate, at the time of each drawdown, plus 9.0%, but not less than 12.5%. The term of each drawdown is 39 months, including nine months of interest-only payments. The loan facility was secured by all of the Company's assets. In March 2021, the Company repaid $570 on outstanding amounts owed on the 2016 WTI loan facility. As of December 31, 2021, tranche three was fully repaid and the Company has no outstanding debt under this facility.

The Company was required to meet certain non-financial covenants in its loan facility agreement. In 2021 and 2020, the Company was in compliance with all non-financial covenants.

*Paycheck Protection Program Loan*

In April 2020, the Company was granted a loan in the amount of $3,065 pursuant to the Paycheck Protection Program (the "PPP Loan") under the Coronavirus Aid, Relief and Economic Security Act. The PPP Loan has a two-year term and bears interest at a rate of 0.98% per annum. Monthly principal and interest payments are deferred for six months after the date of disbursement. The PPP Loan may be prepaid at any time prior to maturity with no prepayment penalties. The PPP Loan contains events of default and other provisions customary for a loan of this type. The PPP Loan may be forgiven if used under program parameters for payroll, mortgage interest, and rent expenses. During 2021 and 2020, the Company was in compliance with the terms of the PPP Loan.

On September 28, 2021, the Company received notice that the obligation of $3,065 had been forgiven, and the Company has no outstanding debt under this program. The Company recorded the gain on extinguishment in the 2021 consolidated statement of operations and comprehensive loss.

**Note 10 — SAFE**

In December 2021, the Company issued a SAFE that allows an investor to participate in future equity financings through a share-settled redemption of the amount invested (such notional being the "invested amount"). Upon the occurrence of a change of control, the investor has the right to receive the greater of (i) a cash payment equal to the invested amount under such SAFE, or (ii) the consideration payable in such change of control in respect of the number of common shares equal to the invested amount divided by the liquidity price set forth in the applicable SAFE. Upon an initial public offering or a business combination with a special purpose acquisition company, the investor has the right to receive a number of common shares equal to the invested amount divided by the liquidity price set forth in the applicable SAFE, except that if a business combination with a special purpose acquisition company involves a private placement of newly issued shares, the invested amount will be treated as participating in such private placement and exchanged for a number of common shares equal to the invested amount divided by the price per share applicable in such private placement (subject to a discount upon certain circumstances).

The SAFE also contains change of control and initial public offering settlement alternatives described above, that settle differently upon a next round financing such that it allows the investor to participate in future equity

------

financings through a share-settled redemption at a discounted price to the price paid by other investors. That is, upon a future equity financing involving preferred shares, the SAFE would be settled into a number of preferred shares equal to the invested amount of the SAFE divided by a percentage of the discounted price investors paid to purchase preferred shares in the financing, with such discounted price calculated as a percentage of the price investors paid to purchase preferred shares in the financing.

The SAFE had not yet converted to equity as a qualifying financing event had not occurred as of December 31, 2021. At December 31, 2021, the SAFE had a fair value of $28,271 and was recorded within current liabilities on the consolidated balance sheet.

**Note 11 — Warrant Liabilities**

In connection with certain loan borrowing agreements and equity raises, the Company issues warrants to purchase preferred shares. The Company evaluated the accounting treatment for the preferred share warrants issued and concluded pursuant to its evaluation of ASC 480, *Distinguishing Liabilities From Equity*, and determined that there is an obligation to issue a variable number of shares and as such, were considered a liability in the consolidated balance sheets. The warrant liability requires the Company to remeasure the value of the underlying warrants and report the effect of the changes on the Company's operations until the warrants are exercised or expired. The primary underlying risk exposure pertaining to the warrants is the change in fair value of the underlying preferred shares for each reporting period.

At December 31, 2021 and 2020, the Company had net operating loss carryforwards of approximately $136,454 and $132,373, respectively, that expire in various years from 2022 through 2037, plus $127,593 and $98,462, respectively, for which there is no expiration date.

Section 382 of the Internal Revenue Code imposes an annual limitation on the utilization of net operating loss carryforwards based on a statutory rate of return and the value of the corporation at the time of a "change of ownership" as defined by Section 382. The Company had a change in ownership in November 2014. Therefore, the Company's ability to utilize its net operating loss carryforwards incurred prior to the 2014 ownership change, will be subject in future periods to annual limitations.

In assessing the realizability of deferred tax assets, the Company assesses whether it is more-likely-than-not that a portion or all of the deferred tax assets will not be realized. The Company considers the scheduled reversal of deferred tax liabilities, tax planning strategies and projected future taxable income in making this assessment. At December 31, 2021 and 2020, a valuation allowance of $113,276 and $108,300, respectively, was recorded against certain deferred tax assets based on this assessment. The Company believes it is more-likely-than-not that the tax benefit of the remaining net deferred tax assets will be realized. The amount of net deferred tax assets considered realizable could be increased or reduced in the future if the Company's assessment of future taxable income or tax planning strategies changes.

------

The Company and its foreign subsidiaries have historically been loss generating entities that have resulted in no excess earnings to consider for repatriation and accordingly there are no deferred income taxes recognized as of December 31, 2021 and 2020.

At December 31, 2021 and 2020, the Company had no tax liability or benefit related to uncertain tax positions. No interest or penalties related to uncertain taxes have been recognized on the accompanying consolidated statements of operations. Management does not expect a significant change in uncertain tax positions during the twelve months subsequent to December 31, 2021.

The Company conducts business in multiple jurisdictions within and outside the United States. Consequently, the Company is subject to periodic income tax examinations by domestic and foreign income tax authorities. During December 2021, the Internal Revenue Service completed an income tax examination of the Company's U.S. federal income tax return for the year ended December 31, 2016, which resulted in no impact to the Company's consolidated financial statements. The Company has no other ongoing tax examinations with domestic or foreign taxing authorities.

During 2021, the Company migrated its country of domicile from New Zealand to Delaware in the United States. On migration, the Company was deemed to have disposed of all its assets and liabilities to a third-party at market value which resulted in taxable income to the Company for New Zealand income tax purposes. The migration to Delaware is classified as a tax-free reorganization for U.S. federal income tax purposes.

**Note 13 — Stock-Based Compensation**

The Company offers share option plans to employees, directors, and others providing consulting services, which meet the definition of an equity-settled stock-based payment.

*Stock Options* 

The Company has five ownership-based participation rights schemes for employees, directors, and certain third-party providers. In accordance with the provisions of the schemes, as approved by the directors and shareholders, grantees have been granted options to purchase common shares at an exercise price based on the fair value price of the Company's common shares on the date of grant as approved by the directors. The stock options generally have a service condition of two to five years and vest over time as the service condition is being satisfied. In November 2020, the Company granted 151,068 options which have a performance condition that accelerates vesting on liquidity event. All stock options have a term of 10 years from the date of grant. Upon termination of employment, unvested stock options are evaluated for forfeiture or modifications, subject to the terms of the awards and Company's policies.

The Company recorded compensation expense of $2,531 and $2,392 for the years ended December 31, 2021 and 2020, respectively. Unrecognized compensation costs as of December 31, 2021 was $6,120 and will be recognized over a weighted average of 2.7 years.

The fair value of each stock option award was estimated on each grant date using the Black-Scholes option pricing model. The following assumptions were used and required significant judgment to determine:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Expected Term* — the Company used the "simplified method" for estimating the expected term of plain-vanilla options, whereby the expected term equals the arithmetic average of the vesting term and LanzaTech's contractual term of the option.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Risk-Free Interest Rate* — The risk-free interest rate is based on the U.S. Treasury zero-coupon instruments with maturities similar to the expected term of LanzaTech's stock options.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Expected Dividend* — the expected dividend yield is based on the Company's expectation of future dividend payouts to common stockholders.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Expected Volatility* — Due to the Company's limited historical data, a group of similar companies that are publicly traded was used to estimate the expected volatility. The historical volatility data was computed using the daily closing prices for the various companies' shares during the equivalent period of the calculated expected term of the stock-based awards.

The following table summarizes the weighted-average assumptions applied in the Black-Scholes valuation of options for awards subject to expense recognition for the first time in the period, for the years ended December 31, 2021 and 2020:

---

| | | |
|:---|:---|:---|
| | **Year Ended December 31,** | **Year Ended December 31,** |
| | **2021** | **2020** |
| Stock price | $9.33 | $4.68 |
| Exercise price | 9.33 | 4.68 |
| Expected term (years) | 6.1 | 6.4 |
| Expected volatility | 98.0% | 100.6% |
| Risk-free interest rate | 1.09% | 0.56% |
| Dividend yield | —% | —% |

---

------

The weighted-average grant date fair value of options granted during 2021 and 2020 was $6.29 and $3.99 per option, respectively.

*Restricted Stock Awards ("RSAs")*

RSAs become eligible to vest upon the satisfaction of a time-based service condition. However, in order to vest, a liquidity event, defined as acquisition, asset transfer, or initial listing, must occur within 10 years from the grant date. Upon a liquidity event, if the participant's service has not terminated, the entire RSA award vests in full, whether or not previously eligible for vesting. If the participant's service has terminated and they have satisfied the time-based service condition, the RSAs that are outstanding and eligible for vesting shall immediately vest in full. The time-based service requirements of the RSAs have a maximum term of three years from the date of grant.

RSAs as of December 31, 2021 and changes during the year ended December 31, 2021 were as follows:

---

| | | |
|:---|:---|:---|
| | **Nonvested Shares (thousands)** | **Weighted Average Fair Value** |
| **Outstanding at January 1, 2021**  | 325 | $4.68 |
| Granted | 281 | 4.76 |
| Forfeited | (26) | 4.68 |
| **Outstanding at December 31, 2021**  | 580 | $4.72 |

---

As of December 31, 2021 and 2020, the Company concluded that the liquidity event performance condition described above for the RSAs was not probable of being satisfied at such time. As a result, the Company did not recognize any compensation cost during the years ended December 31, 2021 and 2020 for any RSAs granted.

**Note 14 — Related Party Transactions**

As of December 31, 2021 and 2020, the Company had an equity ownership in LanzaJet and SGLT with an aggregate carrying value of $24,752 and $23,217, respectively. Trade receivables and contract assets of $1,071 and $3,257, from these equity method investees are included in accounts receivable, respectively. The Company made purchases and had open accounts payable of $2,575 as of and for the year ended December 31, 2021. The accounts payable balance is for work that LanzaJet performed as a subcontractor to the Company. Refer to Note 5 - *Investment*s, for more information.

In connection with the formation of LanzaJet, the Company entered into a transition services agreement with LanzaJet. The transition services agreement generally sets out the respective rights, responsibilities and obligations of the Company and LanzaJet with respect to R&D services, business development and other administrative support services. The transition services agreement may be terminated by mutual consent of the Company and LanzaJet, by LanzaJet at any time, and by the Company upon breach or non-payment by LanzaJet. There are no substantive termination penalties in the event the Company terminates. During the years ended December 31, 2021 and 2020, the Company recognized revenue from related parties of approximately $495 and $285, respectively, under the transition services agreement. The Company provides certain engineering and other services related to a gas-to-jet demonstration plant currently in development by LanzaJet pursuant to the Investment Agreement described in Note 5 - *Investments*. As a result, during the years ended December 31, 2021 and 2020, the Company recognized revenue from related parties of approximately $428 and $2,740, respectively.

The Company supplies SGLT with its biocatalyst, certain water-soluble organic compounds required in the Company's proprietary gas fermentation process, and small-size equipment. As a result, during 2021 and 2020 the Company recognized revenue from related parties of approximately $282 and $156, respectively. The Company also provided engineering services and incurred costs of $1,223 and $242 during the years ended December 31, 2021 and 2020, respectively.

Additionally, LanzaTech and SGLT entered into a license agreement in 2019, subsequently amended in 2021, to provide SGLT with the right to sublicense the intellectual property that LanzaTech previously licensed to SGLT. In

------

exchange, the Company is entitled to receive licensing consideration, calculated as a percentage of the royalties received by SGLT from the sublicenses. Currently, SGLT sublicenses to certain of its subsidiaries that use LanzaTech's proprietary technology. The royalties to be received by SGLT are based on sales-and-usage of the sublicensed technology. For the years ended December 31, 2021 and 2020, the Company did not earn any sublicensing revenue as no royalties were received by SGLT.

**Note 15 — Shareholders' Equity**

The Company records all preferred shares net of offering costs at their respective fair values on the dates of issuance. The preferred shares are classified outside of shareholders' (deficit) equity in the consolidated financial statements, as the preferred shares are redeemable under circumstances that qualify as a deemed liquidation event, which are outside the control of the Company. Upon the occurrence of a liquidation event, such as a voluntary or involuntary liquidation, dissolution or winding up of the Company, merger, consolidation, or change in control, the holders of Series E preferred stock are entitled, on a pari passu basis, to be paid out of the assets of the Company available for distribution before any payment is made to the holders of Series A, B, C, and D preferred shares and then to holders of common shares. In February 2020, the Company closed a Series E follow-on round with the issuance of 2,034,212 Series E preferred shares for net proceeds of $46,470 ($22.86 per share). In March 2021, a warrant was exercised for a total issuance of 158,058 Series D preferred shares and net proceeds of $3,150 ($19.93 per share). In April 2021, the Company closed a Series F round with the issuance of 3,634,210 Series F preferred shares for the net proceeds of $83,073 ($22.86 per share).

The holders of preferred shares are entitled to cast the number of votes equal to the number of whole common shares into which the preferred shares are convertible. The holders of preferred shares also have consent rights, including in a number of cases subject to a separate class vote and a supermajority requirement, over certain actions including, among others (i) alterations or changes to the terms of the preferred shares, (ii) the election of a certain number of directors, including the designation of directors by holders of a specified series of preferred shares or by certain specified individual stockholders, and (iii) repurchases of shares, the authorization or designation of more senior class or series of shares, or certain issuances of new shares.

Preferred shares are convertible at the holder's option into common shares generally on a share-for-share basis. Each preferred share will be automatically converted into common stock upon either (i) the determination of the holders of certain requisite preferred shares or (ii) a firmly underwritten initial public offering of the Company's shares that satisfies certain requirements (but not, for the avoidance of doubt, upon a business combination with a special purpose acquisition company, unless such conversion is otherwise effected pursuant to clause (i) above).

The holders of preferred shares are entitled to receive dividends on an as converted to common shares basis as if all preferred shares had been converted into common shares on the date of such event. Dividends are cumulative and are payable in arrears at the rate of 8% of the original issue price. If dividends are payable on common shares, preferred shareholders also receive those dividends as if the preferred shares had been converted to common shares. Series D, E, and F preferred shareholders are entitled to be paid dividends prior to Series A, B, and C, on a pari passu basis.

Redemption features of preferred shares are not fixed and do not have a determinable price on fixed or determinable dates. As of December 31, 2021 and 2020, preferred shares are not currently redeemable, and it is not probable that preferred shares will become redeemable, since it is uncertain whether or when circumstances exist

that would constitute a deemed liquidation event. Accordingly, the Company has not adjusted the carrying value of the preferred shares to their redemption values.

**Note 17 – Benefit Plans**

The Company sponsors a 401(k) defined contribution retirement plan for the benefit of its employees, substantially all of whom are eligible to participate after meeting minimum qualifying requirements. Contributions to the plan are at the discretion of the Company. For the years ended December 31, 2021 and 2020, the Company contributed $720 and $548, respectively, to the plan, which contributions are included within research and development expense in the consolidated statements of operations and comprehensive loss.

**Note 18 — Commitments and Contingencies**

***Litigation***

The Company may be involved in legal proceedings and exposed to potential claims in the normal course of business. As of December 31, 2021 and December 31, 2020, it is not probable that the Company has incurred any losses from such claims.

**Note 19 — Leases** 

The Company leases certain office space and laboratory facilities. The Company's lease agreements typically do not contain any significant guarantees of asset values at the end of a lease, renewal options or restrictive covenants. Pursuant to the Company's adoption of ASC 842, Leases, all leases were classified as operating leases. During 2021 and 2020, the discount rate used in the calculation of lease liabilities was 7.5%, which is the estimate of the rate of interest that the Company would have to pay to borrow on a collateralized basis over a similar term.

Total operating lease costs and variable lease costs for the years ended December 31, 2021 and 2020 were $2,126 and $2,077 and $2,575 and $1,813, respectively. Cash paid for amounts included in the measurement of operating lease liabilities for the years ended December 31, 2021 and 2020 was $2,059 and $1,765, respectively.

As of December 31, 2021, lease payments for operating leases for the Company's office facility and laboratories are shown below (in thousands):

*Lessor Accounting*

In May 2020, the Company executed an agreement to lease certain land to a subsidiary of LanzaJet for a period of 10 years with an option to renew this lease for five additional periods of one year with minimum annual rent due. This agreement is accounted for as an operating lease. We recognize lease revenue on a straight-line basis over the life of the lease agreement. The following future minimum lease payments due to us from the lease agreement at December 31, 2021, is as follows (in thousands)

***Proposed Merger***

On March 8, 2022, the Company entered into an Agreement and Plan of Merger (the "Merger Agreement") with AMCI Acquisition Corp. II, a Delaware corporation ("AMCI") and AMCI Merger Sub, Inc., a Delaware corporation and a wholly owned subsidiary of AMCI ("Merger Sub"). Under the Merger Agreement, Merger Sub will merge with and into LanzaTech, with LanzaTech surviving the Merger as a wholly-owned subsidiary of AMCI ("the Merger"). In connection with the Merger, AMCI will be renamed LanzaTech Global, Inc ("New LanzaTech"). AMCI has agreed to acquire all of the outstanding equity interests of LanzaTech for consideration consisting of an equity interest of New LanzaTech valued at approximately $1.8 billion. Completion of the transaction is subject to certain customary regulatory consents and approval by stockholders of AMCI and the Company.

In connection with the Merger Agreement, on March 8, 2022, AMCI entered into subscription agreements with certain investors pursuant to which AMCI agreed to issue and sell a private placement to close immediately prior to the Merger.

**Item 14.**

**Indemnification of Directors and Officers**

Our second amended and restated certificate of incorporation (our "Charter") provides that all of our directors, officers, employees and agents shall be entitled to be indemnified by us to the fullest extent permitted by Section 145 of the Delaware General Corporation Law ("DGCL"). Section 145 of the DGCL concerning indemnification of officers, directors, employees and agents is set forth below.

Section 145. Indemnification of officers, directors, employees and agents; insurance.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)A corporation shall have power to indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the corporation) by reason of the fact that the person is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys' fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by the person in connection with such action, suit or proceeding if the person acted in good faith and in a manner the person reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe the person's conduct was unlawful. The termination of any action, suit or proceeding by judgment, order, settlement, conviction, or upon a plea of nolo contendere or its equivalent, shall not, of itself, create a presumption that the person did not act in good faith and in a manner which the person reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had reasonable cause to believe that the person's conduct was unlawful.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)A corporation shall have power to indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the corporation to procure a judgment in its favor by reason of the fact that the person is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise against expenses (including attorneys' fees) actually and reasonably incurred by the person in connection with the defense or settlement of such action or suit if the person acted in good faith and in a manner the person reasonably believed to be in or not opposed to the best interests of the corporation and except that no indemnification shall be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to the corporation unless and only to the extent that the Court of Chancery or the court in which such action or suit was brought shall determine upon application that, despite the adjudication of liability but in view of all

------

the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which the Court of Chancery or such other court shall deem proper.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)To the extent that a present or former director or officer of a corporation has been successful on the merits or otherwise in defense of any action, suit or proceeding referred to in subsections (a) and (b) of this section, or in defense of any claim, issue or matter therein, such person shall be indemnified against expenses (including attorneys' fees) actually and reasonably incurred by such person in connection therewith.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)Any indemnification under subsections (a) and (b) of this section (unless ordered by a court) shall be made by the corporation only as authorized in the specific case upon a determination that indemnification of the present or former director, officer, employee or agent is proper in the circumstances because the person has met the applicable standard of conduct set forth in subsections (a) and (b) of this section. Such determination shall be made, with respect to a person who is a director or officer at the time of such determination, (1) by a majority vote of the directors who are not parties to such action, suit or proceeding, even though less than a quorum, or (2) by a committee of such directors designated by majority vote of such directors, even though less than a quorum, or (3) if there are no such directors, or if such directors so direct, by independent legal counsel in a written opinion, or (4) by the stockholders.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e)Expenses (including attorneys' fees) incurred by an officer or director in defending any civil, criminal, administrative or investigative action, suit or proceeding may be paid by the corporation in advance of the final disposition of such action, suit or proceeding upon receipt of an undertaking by or on behalf of such director or officer to repay such amount if it shall ultimately be determined that such person is not entitled to be indemnified by the corporation as authorized in this section. Such expenses (including attorneys' fees) incurred by former officers and directors or other employees and agents may be so paid upon such terms and conditions, if any, as the corporation deems appropriate.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f)The indemnification and advancement of expenses provided by, or granted pursuant to, the other subsections of this section shall not be deemed exclusive of any other rights to which those seeking indemnification or advancement of expenses may be entitled under any bylaw, agreement, vote of stockholders or disinterested directors or otherwise, both as to action in such person's official capacity and as to action in another capacity while holding such office. A right to indemnification or to advancement of expenses arising under a provision of the certificate of incorporation or a bylaw shall not be eliminated or impaired by an amendment to such provision after the occurrence of the act or omission that is the subject of the civil, criminal, administrative or investigative action, suit or proceeding for which indemnification or advancement of expenses is sought, unless the provision in effect at the time of such act or omission explicitly authorizes such elimination or impairment after such action or omission has occurred.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(g)A corporation shall have power to purchase and maintain insurance on behalf of any person who is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise against any liability asserted against such person and incurred by such person in any such capacity, or arising out of such person's status as such, whether or not the corporation would have the power to indemnify such person against such liability under this section.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(h)For purposes of this section, references to "the corporation" shall include, in addition to the resulting corporation, any constituent corporation (including any constituent of a constituent) absorbed in a consolidation or merger which, if its separate existence had continued, would have had power and authority to indemnify its directors, officers, and employees or agents, so that any person who is or was a director, officer, employee or agent of such constituent corporation, or is or was serving at the request of such constituent corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, shall stand in the same position under this section with respect to the resulting or surviving corporation as such person would have with respect to such constituent corporation if its separate existence had continued.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i)For purposes of this section, references to "other enterprises" shall include employee benefit plans; references to "fines" shall include any excise taxes assessed on a person with respect to any employee benefit plan; and references to "serving at the request of the corporation" shall include any service as a director, officer, employee or agent of the corporation which imposes duties on, or involves services by, such director, officer, employee or agent with respect to an employee benefit plan, its participants or beneficiaries; and a person who acted in good faith and in a manner such person reasonably believed to be in the interest of the participants and beneficiaries of an employee benefit plan shall be deemed to have acted in a manner "not opposed to the best interests of the corporation" as referred to in this section.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(j)The indemnification and advancement of expenses provided by, or granted pursuant to, this section shall, unless otherwise provided when authorized or ratified, continue as to a person who has ceased to be a director, officer, employee or agent and shall inure to the benefit of the heirs, executors and administrators of such a person.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(k)The Court of Chancery is hereby vested with exclusive jurisdiction to hear and determine all actions for advancement of expenses or indemnification brought under this section or under any by law, agreement, vote of stockholders or disinterested directors, or otherwise. The Court of Chancery may summarily determine a corporation's obligation to advance expenses (including attorneys' fees).

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to our directors, officers, and controlling persons pursuant to the foregoing provisions, or otherwise, we have been advised that, in the opinion of the SEC, such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment of expenses incurred or paid by a director, officer or controlling person in a successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, we will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to the court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

In accordance with Section 102(b)(7) of the DGCL, our Charter provides that no director shall be personally liable to us or any of our stockholders for monetary damages resulting from breaches of their fiduciary duty as directors, except to the extent such limitation on or exemption from liability is not permitted under the DGCL. The effect of this provision of our Charter is to eliminate our rights and those of our stockholders (through stockholders' derivative suits on our behalf) to recover monetary damages against a director for breach of the fiduciary duty of care as a director, including breaches resulting from negligent or grossly negligent behavior, except, as restricted by Section 102(b)(7) of the DGCL. However, this provision does not limit or eliminate our rights or the rights of any stockholder to seek non-monetary relief, such as an injunction or rescission, in the event of a breach of a director's duty of care.

If the DGCL is amended to authorize corporate action further eliminating or limiting the liability of directors, then, in accordance with our Charter, the liability of our directors to us or our stockholders will be eliminated or limited to the fullest extent authorized by the DGCL, as so amended. Any repeal or amendment of provisions of our Charter limiting or eliminating the liability of directors, whether by our stockholders or by changes in law, or the adoption of any other provisions inconsistent therewith, will (unless otherwise required by law) be prospective only, except to the extent such amendment or change in law permits us to further limit or eliminate the liability of directors on a retroactive basis.

Our Charter also provides that we will, to the fullest extent authorized or permitted by applicable law, indemnify our current and former officers and directors, as well as those persons who, while directors or officers of our corporation, are or were serving as directors, officers, employees or agents of another entity, trust or other enterprise, including service with respect to an employee benefit plan, in connection with any threatened, pending or completed proceeding, whether civil, criminal, administrative or investigative, against all expense, liability and loss (including, without limitation, attorney's fees, judgments, fines, ERISA excise taxes and penalties and amounts paid in settlement) reasonably incurred or suffered by any such person in connection with any such proceeding.

------

Notwithstanding the foregoing, a person eligible for indemnification pursuant to our Charter will be indemnified by us in connection with a proceeding initiated by such person only if such proceeding was authorized by our board of directors, except for proceedings to enforce rights to indemnification.

The right to indemnification which is conferred by our Charter is a contract right that includes the right to be paid by us the expenses incurred in defending or otherwise participating in any proceeding referenced above in advance of its final disposition, provided, however, that if the DGCL requires, an advancement of expenses incurred by our officer or director (solely in the capacity as an officer or director of our corporation) will be made only upon delivery to us of an undertaking, by or on behalf of such officer or director, to repay all amounts so advanced if it is ultimately determined that such person is not entitled to be indemnified for such expenses under our Charter or otherwise.

The rights to indemnification and advancement of expenses will not be deemed exclusive of any other rights which any person covered by our Charter may have or hereafter acquire under law, our Charter, our amended and restated bylaws (the "Bylaws"), an agreement, vote of stockholders or disinterested directors, or otherwise.

Any repeal or amendment of provisions of our Charter affecting indemnification rights, whether by our stockholders or by changes in law, or the adoption of any other provisions inconsistent therewith, will (unless otherwise required by law) be prospective only, except to the extent such amendment or change in law permits us to provide broader indemnification rights on a retroactive basis, and will not in any way diminish or adversely affect any right or protection existing at the time of such repeal or amendment or adoption of such inconsistent provision with respect to any act or omission occurring prior to such repeal or amendment or adoption of such inconsistent provision. Our Charter will also permit us, to the extent and in the manner authorized or permitted by law, to indemnify and to advance expenses to persons other that those specifically covered by our Charter.

Our Bylaws include the provisions relating to advancement of expenses and indemnification rights consistent with those which are set forth in our Charter. In addition, our Bylaws provide for a right of indemnity to bring a suit in the event a claim for indemnification or advancement of expenses is not paid in full by us within a specified period of time. Our Bylaws also permit us to purchase and maintain insurance, at our expense, to protect us and/or any director, officer, employee or agent of our corporation or another entity, trust or other enterprise against any expense, liability or loss, whether or not we would have the power to indemnify such person against such expense, liability or loss under the DGCL.

Any repeal or amendment of provisions of our Bylaws affecting indemnification rights, whether by our board of directors, stockholders or by changes in applicable law, or the adoption of any other provisions inconsistent therewith, will (unless otherwise required by law) be prospective only, except to the extent such amendment or change in law permits us to provide broader indemnification rights on a retroactive basis, and will not in any way diminish or adversely affect any right or protection existing thereunder with respect to any act or omission occurring prior to such repeal or amendment or adoption of such inconsistent provision.

In connection with our consummation of the Business Combination, we entered into customary indemnification agreements with our directors and executive officers.

**Recent Sale of Unregistered Securities** 

The following list sets forth information regarding all unregistered securities sold by us since inception:

1)On January 29, 2021, the Sponsor subscribed for an aggregate 5,031,250 shares of AMCI Class B common stock, par value $0.0001 per share (the "Founder Shares") for a total subscription price of $25,000, or approximately $0.005 per share. In March 2021, the Sponsor transferred all of the Founder Shares held by it to members of the AMCI's board of directors, its management team and persons or entities affiliated with AMCI Group. On May 14, 2021, certain of AMCI's initial stockholders forfeited an aggregate of 718,750 Founder Shares, resulting in an aggregate of 4,312,500 Founder Shares outstanding. On September 17,

------

2021, the over-allotment option expired and therefore, the initial stockholders forfeited 562,500 Founder Shares, resulting in an aggregate of 3,750,000 Founder Shares outstanding.

2)Simultaneous with the consummation of AMCI's Initial Public Offering, the Sponsor purchased 3,500,000 Private Placement Warrants at a price of $1.00 per Private Placement Warrant, generating gross proceeds of $3.5 million. No underwriting discounts or commissions were paid with respect to such sales. This issuance was made pursuant to the exemption from registration contained in Section 4(a)(2) of the Securities Act.

3)On February 8, 2023, pursuant to certain non-redemption agreements dated February 3, 2023 and February 6, 2023, AMCI issued and sold 1,250,000 shares of AMCI Class A common stock to certain qualified institutional buyers and accredited investors.

4)On February 8, concurrently with the closing of the Business Combination, we issued 18,500,000 shares of common stock for an aggregate purchase price of $185.0 million to certain qualified institutional buyers and accredited investors, at a price of $10.00 per share.

5)On February 8, AMCI issued and sold 469,052 shares of AMCI Class A common stock to certain Anchor Investors.

6)Upon the closing of the Business Combination, unvested options to purchase an aggregate of 3,271,104 shares of Legacy LanzaTech common stock at exercise prices of approximately $0.70 to $43.60 per share under the Legacy LanzaTech Plans were automatically and without any required action on the part of any holder or beneficiary thereof, assumed by us and converted into options to purchase an aggregate of 14,310,025 shares of common stock at exercise prices of approximately $0.16 to $9.97.

None of the foregoing transactions involved any underwriters, underwriting discounts or commissions, or any public offering. We believe each of these transactions was exempt from registration under the Securities Act in reliance on Section 4(a)(2) of the Securities Act (and Regulation D promulgated thereunder) as transactions by an issuer not involving any public offering or Rule 701 promulgated under Section 3(b) of the Securities Act as transactions by an issuer under benefit plans and contracts relating to compensation as provided under Rule 701. The recipients of the securities in each of these transactions represented their intentions to acquire the securities for investment only and not with a view to or for sale in connection with any distribution thereof, and appropriate legends were placed on the share certificates issued in these transactions. All recipients had adequate access, through their relationships with us, to information about us. The sales of these securities were made without any general solicitation or advertising.

**Item 17.**

**Undertakings.** 

The undersigned registrant hereby undertakes:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1)To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i)To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933 (the "Securities Act");

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii)To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the SEC pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20% change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective registration statement; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii)To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;

------

*provided, however*, that the undertakings set forth in paragraphs (1)(i), (1)(ii) and (1)(iii) above do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the SEC by the registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), that are incorporated by reference in this registration statement or are contained in a form of prospectus filed pursuant to Rule 424(b) that is part of this registration statement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2)That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3)To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(4)That, for the purpose of determining liability under the Securities Act to any purchaser, each prospectus filed pursuant to Rule 424(b) as part of a registration statement relating to an offering, other than registration statements relying on Rule 430B or other than prospectuses filed in reliance on Rule 430A, shall be deemed to be part of and included in the registration statement as of the date it is first used after effectiveness. *Provided, however*, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such first use, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such date of first use.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(5)That, for the purpose of determining liability of the registrant under the Securities Act to any purchaser in the initial distribution of the securities, the undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i)Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii)Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii)The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv)Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(6)Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

------

We have reviewed:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i)&nbsp;&nbsp;&nbsp;&nbsp;the Warrant Agreement,

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii)&nbsp;&nbsp;&nbsp;&nbsp;the Brookfield SAFE,

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii)&nbsp;&nbsp;&nbsp;&nbsp;the AM Warrant,

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv)&nbsp;&nbsp;&nbsp;&nbsp;the Registration Rights Agreement by and among the Company, LanzaTech NZ, Inc., AMCI Sponsor II LLC, and the Holders (as defined therein), dated February 8, 2023,

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(v)&nbsp;&nbsp;&nbsp;&nbsp;the Forward Purchase Agreement by and among ACM ARRT H LLC, the Company and LanzaTech NZ, Inc., dated February 3, 2023,

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(vi)&nbsp;&nbsp;&nbsp;&nbsp;the Assignment and Novation Agreement, by and among AMCI Acquisition Corp. II, LanzaTech NZ, Inc., ACM ARRT H LLC, and and Vellar Opportunity Fund SPV LLC - Series 10, dated February 3, 2023,

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(vii)&nbsp;&nbsp;&nbsp;&nbsp;the Plans and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(viii)&nbsp;&nbsp;&nbsp;&nbsp;such other corporate records, certificates and other documents, and such questions of law, as we have considered necessary or appropriate for the purposes of this opinion.

We have assumed that all signatures are genuine, that all documents submitted to us as originals are authentic and that all copies of documents submitted to us conform to the originals.

We have relied as to certain matters on information obtained from public officials, officers of the Company and other sources believed by us to be responsible.

With respect to the Convertible Security Shares, we express no opinion to the extent that, notwithstanding the Company's current reservation of shares of common stock, future issuances of securities of the Company, including the Convertible Security Shares, and anti-dilution adjustments to outstanding securities of the Company, including the Warrants, the Brookfield SAFE and the AM Warrant, may cause any of the foregoing to be exercisable for more shares of common stock than the number that remain authorized but unissued. We also have assumed that the Warrant Price (as defined in each of the Private Warrants, the Public Warrants) and the Exercise Price (as defined in the AM Warrant) will not be adjusted to an amount below the par value per share of the common stock.

Based upon the foregoing, and subject to the qualifications set forth below, we are of the opinion that:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1)&nbsp;&nbsp;&nbsp;&nbsp;The Warrant Shares have been duly authorized and, when issued and paid for upon exercise of the Warrants, in accordance with the terms of the Warrants, will be validly issued, fully paid and non-assessable.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2)&nbsp;&nbsp;&nbsp;&nbsp;The SAFE Shares have been duly authorized and, when issued upon conversion of the Brookfield SAFE, in accordance with the terms of the Brookfield SAFE, will be validly issued, fully paid and non-assessable.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3)&nbsp;&nbsp;&nbsp;&nbsp;The AM Shares have been duly authorized and, when issued and paid for upon exercise of the AM Warrant, in accordance with the terms of the AM Warrant, will be validly issued, fully paid and non-assessable.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(4)&nbsp;&nbsp;&nbsp;&nbsp;The Plan Shares have been duly authorized and, when issued and paid for in accordance with the terms of the Plan upon the exercise thereof, will be validly issued, fully paid and non-assessable.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(5)&nbsp;&nbsp;&nbsp;&nbsp;The Resale Shares have been duly authorized and are validly issued, fully paid and non-assessable.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(6)&nbsp;&nbsp;&nbsp;&nbsp;The Resale Warrants have been duly authorized and constitute the valid and binding obligations of the Company, enforceable against the Company in accordance with their terms, subject to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and other laws of general applicability relating to or affecting creditors' rights and to general equity principles.

The foregoing opinion is subject to the following qualifications. We express no opinion as to: (i) waivers of defenses, subrogation and related rights, rights to trial by jury, rights to object to venue, or other rights or benefits bestowed by operation of law; (ii) releases or waivers of unmatured claims or rights; (iii) indemnification, contribution, or exculpation provisions, or provisions for the non-survival of representations, to the extent they purport to indemnify any party against, or release or limit any party's liability for, its own breach or failure to comply with statutory obligations, or to the extent such provisions are contrary to public policy; (iv) provisions for liquidated damages and penalties, penalty interest and interest on interest; (v) provisions requiring amendments and waivers to be in writing; (vi) provisions making notices effective even if not actually received; (vii) exclusive jurisdiction or venue provisions or (viii) provisions purporting to make a party's determination conclusive.

We are members of the bar of the District of Columbia and the State of New York. We do not express any opinion herein on any laws other than the Delaware General Corporation Law and the State of New York.

We hereby consent to the filing of this opinion as Exhibit 5.1 to the Registration Statement. We also hereby consent to the reference to our firm under the heading "Legal Matters" in the prospectus constituting part of the Registration Statement. In giving such consent, we do not thereby admit that we are in the category of persons whose consent is required under Section 7 of the Securities Act.
