**Item 1.01&nbsp;&nbsp;&nbsp;&nbsp;Entry into a Material Definitive Agreement.**

***Subscription Agreements***

On January 21, 2026 (the "Closing Date") LanzaTech Global, Inc. (the "Company") entered into subscription agreements ("Subscription Agreements") with certain existing and new institutional investors (the "Investors"), pursuant to which the Investors purchased, in private placements, shares (the "Subscribed Shares") of common stock, par value $0.0000001 per share ("Common Stock"), of the Company, for cash. Pursuant to the Subscription Agreements, on the Closing Date, the Company issued and sold a total of 4,000,000 Subscribed Shares to the Investors at a per share purchase price of $5.00 (the "Purchase Price"), resulting in gross proceeds to the Company of $20,000,000. In consideration for funding the Purchase Price no later than January 21, 2026, the Company issued to the Investors an aggregate number of bonus shares (the "Bonus Shares" and, together with the Subscribed Shares, the "PIPE Shares") equal to 510,968 shares of Common Stock (the "PIPE Transactions"). The Subscription Agreement with the largest Investor provides that, for so long as such Investor holds shares of Common Stock in an amount equal to at least 50% of its Subscribed Shares (as adjusted for certain events), such Investor will be entitled to appoint one observer to the Company's Board of Directors, subject to the provisions set forth in such Investor's Subscription Agreement.

The offer and issuance of the PIPE Shares was not registered under the Securities Act of 1933, as amended (the "Securities Act"), or any state securities laws. The PIPE Shares were issued in reliance on the exemption from registration provided by Section 4(a)(2) under the Securities Act. The Company is not required to file a registration statement providing for the resale of the PIPE Shares.

***Second Amended and Restated Certificate of Designation***

As previously disclosed, on May 7, 2025, the Company and LanzaTech Global SPV, LLC, an entity controlled by an existing investor (the "Preferred Stockholder"), entered into that certain Series A Convertible Senior Preferred Stock Purchase Agreement (as amended, restated, supplemented or otherwise modified from time to time, the "Purchase Agreement"), pursuant to which the Company issued and sold 20,000,000 shares of the Company's preferred stock designated as "Series A Convertible Senior Preferred Stock" (the "Preferred Stock") to the Preferred Stockholder, on May 7, 2025, for an aggregate purchase price of $40,000,000, which shares were convertible at any time at the option of the Preferred Stockholder into 200,000 shares of Common Stock. On the Closing Date, the Company filed a Second Amended and Restated Certificate of Designation of Series A Convertible Senior Preferred Stock (the "A&R CoD") with the Office of the Secretary of State of the State of Delaware. The A&R CoD: (i) provides for the mandatory conversion of all of the Preferred Stock into an aggregate of 3,250,322 shares of Common Stock (the "Conversion Shares") in certain circumstances, including upon the consummation of an Other Financing (as defined in the A&R CoD) occurring on or prior to January 21, 2026 pursuant to which the Company issues and sells shares of Common Stock for an aggregate gross purchase price, payable in cash, of not less than $20,000,000; (ii) eliminates all provisions requiring the Company to effect a mandatory redemption of the Preferred Stock upon certain events; and (iii) makes certain other technical, conforming, clarifying and other changes, including to reflect the foregoing.

The consummation of the PIPE Transactions on the Closing Date triggered the mandatory conversion of the Preferred Stock into the Conversion Shares pursuant to the A&R CoD. As a result, all outstanding shares of the Preferred Stock were automatically converted into the Conversion Shares as of the Closing Date and the Company issued the Conversion Shares to the Preferred Stockholder on the Closing Date pursuant to the terms of the A&R CoD.

***Warrant***

As previously disclosed, pursuant to the Purchase Agreement, the Company also agreed to issue to the Preferred Stockholder, immediately prior to the consummation of certain financings (including an Other Financing) (such time, the "Issuance Time"), a warrant to purchase 7,800,000 shares of Common Stock at an exercise price equal to $0.0000001 per share (the "Warrant Shares") (subject to adjustments in certain events) (the "Warrant"), which Warrant would be deemed automatically exercised on a cashless, net-exercise basis at such time. In connection with the consummation of the PIPE Transactions, the Company and the Preferred Stockholder agreed to amend the terms of the Warrant to provide that, subject to the terms and conditions set forth in the Warrant, the Warrant is not automatically exercised at the Issuance Time but rather is exercisable at any time prior to 5:00 p.m. New York City time on December 31, 2026 (the "Expiration Time") and will be automatically exercised on a cashless, net-exercise basis immediately prior to the Expiration Time.

------

The Warrant will terminate and become void as of the Expiration Time. The Warrant was issued to the Preferred Stockholder concurrently with the closing of the PIPE Transactions.

***Waiver Agreement***

On the Closing Date, the Company and the Preferred Stockholder entered into a Waiver Agreement (the "Waiver Agreement"), pursuant to which the Preferred Stockholder waived the obligation of the Company under the Registration Rights Agreement, dated as of May 7, 2025 (as amended, restated, supplemented or otherwise modified from time to time, the "Registration Rights Agreement"), between the Company and the Preferred Stockholder, to file a registration statement with respect to certain shares of Common Stock (the "Registration Statement") no later than 10 business days following the issuance of the Warrant Shares, and the Company agreed to file the Registration Statement no later than 60 business days following the issuance to the Preferred Stockholder of the Warrant Shares.

The foregoing summaries of the Subscription Agreements, the A&R CoD, the Warrant and the Waiver Agreement do not purport to be complete and are qualified in their entirety by the full text of the form of Subscription Agreement, the A&R CoD, the Warrant and the Waiver Agreement, copies of which are being filed as Exhibits 10.1, 3.1, 10.2 and 10.3, respectively, to this Current Report on Form 8-K, and are incorporated by reference herein.

The issuance of the Conversion Shares to the Preferred Stockholder was made in reliance upon an exemption from the registration requirements of the Securities Act, pursuant to Section 3(a)(9) thereof.

NOW THEREFORE, BE IT RESOLVED, that, pursuant to the authority expressly vested in the Board and in accordance with the provisions of the Certificate of Incorporation and the DGCL, the First A&R COD, as amended, shall be amended and restated, such that the designations, powers, preferences and relative, participating, optional, special and other rights, and the qualifications, limitations and restrictions of, the Series A Preferred Stock shall be, as follows: 1.

Ranking; Liquidation, Dissolution or Winding Up; Certain Mergers, Consolidations and Asset Sales. (a) Ranking Generally. The Series A Preferred Stock shall rank senior to the Junior Stock in priority of payment in all respects, including with respect to (i) distribution of assets, (ii) distributions in connection with any Liquidation Event or Deemed Liquidation Event, and (iii) all other redemption rights. (b) Preferential Payments to Holders of Preferred Stock. In the event of, as applicable, (i) any Liquidation Event, the Holders shall be entitled to be paid out of the assets of the Company available for distribution to its stockholders, which may include any distribution made pursuant to a plan under chapter 11 of the Bankruptcy Code (or its equivalent), and (ii) any Deemed Liquidation Event, the Holders shall be entitled to be paid out of the consideration payable to stockholders in such Deemed Liquidation Event or out of the Available Proceeds, in each case, on a pari passu basis and before any payment shall be made to the holders of Junior Stock by reason of their ownership thereof, an amount per share of Series A Preferred Stock equal to the greater of (A) the Liquidation Value as of such date of determination, (B) such amount per share as would have been payable had all shares of such Series A Preferred Stock been converted into Common Stock pursuant to Section 5 immediately prior to such Liquidation Event or Deemed Liquidation Event, and (C) solely with respect to a Liquidation Event, the Minimum Liquidation Value (the amount payable pursuant to this sentence is hereinafter referred to as the "Payment Amount"). If upon any such Liquidation Event or Deemed Liquidation Event, the assets of the Company available for distribution to its stockholders shall be insufficient to pay the Holders the full Payment Amount to which they shall be entitled under this Section 2(b), the Holders shall share ratably in any distribution of the assets available for distribution, on a pari passu basis and in proportion to the respective amounts which would otherwise be payable in respect of the shares of Series A Preferred Stock held by them upon such distribution if all amounts payable on or with respect to such shares were paid in full. (c) Effecting a Deemed Liquidation Event. The Company shall not have the power to effect a Deemed Liquidation Event, and shall not effect a Deemed Liquidation Event, unless the definitive agreement or plan with respect to such transaction or the terms of such transaction (any such agreement, plan or terms, the "Transaction Document") provides that the consideration payable to the stockholders of the Company in such Deemed Liquidation Event shall be allocated to the holders of capital stock of the Company in accordance with this Section 2.

&nbsp;&nbsp;&nbsp;&nbsp;4 4. Dividends. (a) Generally. Subject to Section 4(c), no dividends (including the Dividend Accruals (as defined in Section 4(b)) shall be declared or paid on the Series A Preferred Stock. No dividend shall be declared or paid, or any other distribution made, on any Junior Stock, except in accordance with Section 8. (b) Dividend Accrual. From and after the Initial Issue Date, preferential cumulative dividends ("Dividend Accruals") shall accrue on each share of Series A Preferred Stock outstanding on a daily basis in arrears at the Dividend Rate. Dividend Accruals with respect to each Dividend Period shall be the sum of the dividends calculated on a daily basis during such period. The daily dividend shall be calculated as the product of (i) the Liquidation Value of each share of the Series A Preferred Stock outstanding as of the Dividend Accrual Date for such Dividend Period, and (ii) 8% (the "Dividend Rate") for each day elapsed during such Dividend Period divided by 360. Dividends will accrue quarterly in arrears on each Dividend Accrual Date and, once accrued, shall not be declared or paid but shall instead be added to the Liquidation Value of such share of Series A Preferred Stock as of the applicable Dividend Accrual Date. For the avoidance of doubt, Dividend Accruals will be deemed to have accrued as of the Initial Issue Date notwithstanding the subsequent amendment and restatement of the Original Certificate of Designation. (c) Dividends or Distributions on Common Stock. Holders of Series A Preferred Stock shall fully participate, on an as-converted basis, in any dividends declared and paid or distributions on Common Stock as if the shares of Series A Preferred Stock were converted into shares of Common Stock (as provided in Section 5) as of the record date for such dividend or distribution. 5. Optional Conversion. (a) Optional Conversion. At any time between January 22, 2026 and May 31, 2026, at the written election of the Majority Holders, acting on behalf of all Holders (with respect to all shares of Series A Preferred Stock then outstanding), and without the payment of additional consideration by the Holder(s), all, but not less than all, of the outstanding shares of Series A Preferred Stock shall be convertible into that number of fully paid and non-assessable shares of Common Stock, in the aggregate, equal to the Conversion Amount (as defined below), in accordance with the terms and conditions of this Section 5. (b) Mechanics of Conversion. (i) Notice of Conversion. In order for the Majority Holders (on behalf of all Holders) to voluntarily convert all, but not less than all, of the shares of Series A Preferred Stock into shares of Common Stock as set forth in Section 5(a), (A) the Majority Holders shall provide written notice to the Company's transfer agent at the office of the transfer agent for the Series A Preferred Stock (or at the principal office of the Company if the Company serves as its own transfer agent) that the Majority Holders elect to convert all, but not less than all, of the then-outstanding shares of Series A Preferred Stock and, if applicable, any event on which such conversion is contingent and (B) if any converting Holder's shares are certificated, such Holder shall surrender the certificate or certificates for such shares of Series A Preferred Stock (or, if such registered holder alleges that such certificate has been lost, stolen or destroyed, a lost certificate affidavit and agreement reasonably acceptable to the Company to indemnify the Company against any claim that may be made against the Company on account of the alleged loss, theft or destruction of such certificate), at the office of the transfer agent for the Series A Preferred Stock (or at the principal office of the Company if the Company serves as its own transfer agent). Such notice shall state such Holder's name and the names of the nominees in which such Holder wishes the shares of Common Stock to be issued. If required by the Company, any certificates surrendered for conversion shall be endorsed or accompanied by a written instrument or instruments of transfer, in

------

![](exhibit31-secondamendeda005.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;5 form satisfactory to the Company, duly executed by the registered Holder or his, her or its attorney duly authorized in writing. The close of business, Eastern Time, on the date of receipt by the transfer agent (or by the Company if the Company serves as its own transfer agent) of such notice and, if applicable, certificates (or lost certificate affidavit and agreement) shall be the time of conversion (the "Conversion Time"), and the shares of Common Stock issuable upon conversion of the specified shares shall be deemed to be outstanding of record as of such date. The Company shall, as soon as practicable after the Conversion Time, issue and deliver to the converting Holder or Holders, or to their nominees, a certificate or certificates for the number of full shares of Common Stock issuable upon such conversion in accordance with the provisions hereof and a certificate for the number (if any) of the shares of Series A Preferred Stock represented by the surrendered certificate that were not converted into Common Stock or, if such shares are uncertificated, register such shares in book-entry form. Delivery of the Common Stock upon conversion pursuant to Section 5(a) shall be deemed to fully satisfy and discharge any obligation with respect to accrued Dividend Accruals on such converted shares of Series A Preferred Stock as of the Conversion Time. (ii) Reservation of Shares. The Company shall at all times following receipt of the Requisite Stockholder Approvals and so long as any shares of Series A Preferred Stock remain outstanding, reserve and keep available out of its authorized but unissued capital stock, for the purpose of effecting the conversion of the Series A Preferred Stock, such number of its duly authorized shares of Common Stock as shall from time to time be sufficient to effect the conversion of all outstanding Series A Preferred Stock. If at any time following receipt of the Requisite Stockholder Approvals the number of authorized but unissued shares of Common Stock shall not be sufficient to effect the conversion of all then outstanding shares of the Series A Preferred Stock, the Company shall take such corporate action as may be necessary to increase its authorized but unissued shares of Common Stock to such number of shares as shall be sufficient for such purposes, including, without limitation, engaging in best efforts to obtain the requisite stockholder approval of any necessary amendment to the Certificate of Incorporation. (iii) Effect of Conversion. All shares of Series A Preferred Stock which shall have been surrendered for conversion as herein provided shall no longer be deemed to be outstanding and all rights with respect to such shares shall immediately cease and terminate at the Conversion Time, except the right of the Holders thereof to receive shares of Common Stock in exchange therefor. (iv) Taxes. The Company shall pay any and all issue and other similar taxes that may be payable in respect of any issuance or delivery of shares of Common Stock upon conversion of Series A Preferred Stock pursuant to this Section 5. The Company shall not, however, be required to pay any tax which may be payable in respect of any transfer involved in the issuance and delivery of shares of Common Stock in a name other than that in which the shares of Series A Preferred Stock so converted were registered, and no such issuance or delivery shall be made unless and until the person or entity requesting such issuance has paid to the Company the amount of any such tax or has established, to the satisfaction of the Company, that such tax has been paid. 6. Mandatory Conversion. (a) Mandatory Conversion Trigger Event. Upon the date that is the earlier to occur of (i) the consummation of an Other Financing occurring on or prior to January 21, 2026 pursuant to which the Company issues and sells shares of Common Stock for an aggregate gross purchase price, payable in cash, of not less than $20,000,000, and (ii) June 1, 2026 (the "Mandatory Conversion Time"), and without the payment of additional consideration by the Holder(s), all, but not less than all, of the outstanding shares of Series A Preferred Stock shall automatically be converted into, in the aggregate, 3,250,322 fully paid

------

![](exhibit31-secondamendeda006.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;6 and non-assessable shares of Common Stock (such amount, the "Conversion Amount"), in accordance with the terms and conditions of this Section 6. (b) Procedural Requirements. All Holders of record of shares of Series A Preferred Stock shall be sent written notice of the Mandatory Conversion Time, if any, and the place designated for mandatory conversion of all such shares of Series A Preferred Stock pursuant to this Section 6. Such notice need not be sent in advance of the occurrence of the Mandatory Conversion Time. Upon receipt of such notice, each Holder of shares of Series A Preferred Stock being converted that holds such shares of Series A Preferred Stock in certificated form shall surrender his, her or its certificate or certificates for all such shares (or, if such Holder alleges that such certificate has been lost, stolen or destroyed, a lost certificate affidavit and agreement reasonably acceptable to the Company to indemnify the Company against any claim that may be made against the Company on account of the alleged loss, theft or destruction of such certificate), at the office of the transfer agent for the Series A Preferred Stock (or at the principal office of the Company if the Company serves as its own transfer agent). If so required by the Company, any certificates surrendered for conversion shall be endorsed or accompanied by a written instrument or instruments of transfer, in form satisfactory to the Company, duly executed by the registered Holder or his, her or its attorney duly authorized in writing. All rights with respect to the Series A Preferred Stock converted pursuant to this Section 6, including the rights, if any, to receive notices and vote (other than as a holder of Common Stock), will terminate at the Mandatory Conversion Time (notwithstanding the failure of the Holder or Holders thereof to surrender any certificates at or prior to such time), except only the rights of the Holders thereof, upon surrender of any certificate or certificates of such Holders (or lost certificate affidavit and agreement) therefor, to receive the items provided for in the next sentence of this Section 6(b). As soon as practicable after the Mandatory Conversion Time and, if applicable, the surrender of any certificate or certificates (or lost certificate affidavit and agreement) for Series A Preferred Stock, the Company shall issue and deliver to such Holder, or to his, her or its nominees, a certificate or certificates for the number of full shares of Common Stock issuable on such conversion in accordance with the provisions hereof or issue and deliver to such Holder, or to his, her or its nominees, a notice of issuance of uncertificated shares and may, upon written request, issue and deliver a certificate for the number of full shares of Common Stock issuable upon such conversion in accordance with the provisions hereof. (c) Incorporation by Reference. The terms and conditions set forth in Section 5(b)(ii)- (iv) are hereby incorporated by this reference into this Section 6, mutatis mutandis. (d) No Call Right. Notwithstanding anything to the contrary in this Certificate of Designation, none of the Series A Preferred Stock shall be redeemable at the election of the Company. 7. MFN Terms. If, at any time while any shares of Series A Preferred Stock are outstanding, the Company shall consummate any financing (including any equity securities, debt securities, indebtedness for borrowed money, digital currency, or otherwise), other than the Subsequent Financing, that contain any economic rights, preferences or privileges or consent rights that are more favorable in any respect to the holder(s) thereof as compared to the terms of the Series A Preferred Stock (such more favorable terms, the "MFN Terms"), then (a) the Company shall provide prior written notice thereof to the Holders, together with a description of such financing instrument and the MFN Terms, and (b) upon written request of the Majority Holders, which request must be delivered to the Company within five days of such notice from the Company, the Company shall seek to amend and restate this Certificate of Designation, the Certificate of Incorporation and/or the other organizational documents of the Company to provide for such

------

Subscriber understands the disadvantage to which Subscriber may be subject on account of the disparity of the access to, and possession of, the information between the Company and such Subscriber. Subscriber has conducted an independent evaluation of the Company's business and securities to determine whether to engage in the transactions contemplated by this Subscription Agreement and, notwithstanding the absence of access by Subscriber to the Excluded Information, the Subscriber is desirous of consummating such transactions.

Part 800.401, and no foreign person will have control (as defined in 31 C.F.R. Part 800.208) over the Company from and after the Closing as a result of the purchase and sale of Subscribed Shares or as a result of the issuance of the Early Funding Bonus Shares hereunder.

NOW THEREFORE, BE IT RESOLVED, that, pursuant to the authority expressly vested in the Board and in accordance with the provisions of the Certificate of Incorporation and the DGCL, the First A&R COD, as amended, shall be amended and restated, such that the designations, powers, preferences and relative, participating, optional, special and other rights, and the qualifications, limitations and restrictions of, the Series A Preferred Stock shall be, as follows: Section 1. Designation. A total of 20,000,000 shares of Preferred Stock, with a par value of $0.0001 per share, shall be designated as a series known as Series A Convertible Senior Preferred Stock (the "Series A Preferred Stock"), with each such share having an initial original issue price ("Original Issue Price") of $2.00 per share, which Series A Preferred Stock will have the respective designations, powers, preferences and relative, participating, optional, special and other rights, and the qualifications, limitations and restrictions set forth in this Certificate of Designation. Section 2. Ranking; Liquidation, Dissolution or Winding Up; Certain Mergers, Consolidations and Asset Sales. (a) Ranking Generally. The Series A Preferred Stock shall rank senior to the Junior Stock in priority of payment in all respects, including with respect to (i) distribution of assets, (ii) distributions in connection with any Liquidation Event or Deemed Liquidation Event, and (iii) all other redemption rights. (b) Preferential Payments to Holders of Preferred Stock. In the event of, as applicable, (i) any Liquidation Event, the Holders shall be entitled to be paid out of the assets of the Company available for distribution to its stockholders, which may include any distribution made pursuant to a plan under chapter 11 of the Bankruptcy Code (or its equivalent), and (ii) any Deemed Liquidation Event, the Holders shall be entitled to be paid out of the consideration payable to stockholders in such Deemed Liquidation Event or out of the Available Proceeds, in each case, on a pari passu basis and before any payment shall be made to the holders of Junior Stock by reason of their ownership thereof, an amount per share of Series A Preferred Stock equal to the greater of (A) the Liquidation Value as of such date of determination, (B) such amount per share as would have been payable had all shares of such Series A Preferred Stock been converted into Common Stock pursuant to Section 5 immediately prior to such Liquidation Event or Deemed Liquidation Event, and (C) solely with respect to a Liquidation Event, the Minimum Liquidation Value (the amount payable pursuant to this sentence is hereinafter referred to as the "Payment Amount"). If upon any such Liquidation Event or Deemed Liquidation Event, the assets of the Company available for distribution to its stockholders shall be insufficient to pay the Holders the full Payment Amount to which they shall be entitled under this Section 2(b), the Holders shall share ratably in any distribution of the assets available for distribution, on a pari passu basis and in proportion to the respective amounts which would otherwise be payable in respect of the shares of Series A Preferred Stock held by them upon such distribution if all amounts payable on or with respect to such shares were paid in full. (c) Effecting a Deemed Liquidation Event. The Company shall not have the power to effect a Deemed Liquidation Event, and shall not effect a Deemed Liquidation Event, unless the definitive agreement or plan with respect to such transaction or the terms of such transaction (any such agreement, plan or terms, the "Transaction Document") provides that the consideration payable to the stockholders of the Company in such Deemed Liquidation Event shall be allocated to the holders of capital stock of the Company in accordance with this Section 2.

&nbsp;&nbsp;&nbsp;&nbsp;4 Section 4. Dividends. (a) Generally. Subject to Section 4(c), no dividends (including the Dividend Accruals (as defined in Section 4(b)) shall be declared or paid on the Series A Preferred Stock. No dividend shall be declared or paid, or any other distribution made, on any Junior Stock, except in accordance with Section 8. (b) Dividend Accrual. From and after the Initial Issue Date, preferential cumulative dividends ("Dividend Accruals") shall accrue on each share of Series A Preferred Stock outstanding on a daily basis in arrears at the Dividend Rate. Dividend Accruals with respect to each Dividend Period shall be the sum of the dividends calculated on a daily basis during such period. The daily dividend shall be calculated as the product of (i) the Liquidation Value of each share of the Series A Preferred Stock outstanding as of the Dividend Accrual Date for such Dividend Period, and (ii) 8% (the "Dividend Rate") for each day elapsed during such Dividend Period divided by 360. Dividends will accrue quarterly in arrears on each Dividend Accrual Date and, once accrued, shall not be declared or paid but shall instead be added to the Liquidation Value of such share of Series A Preferred Stock as of the applicable Dividend Accrual Date. For the avoidance of doubt, Dividend Accruals will be deemed to have accrued as of the Initial Issue Date notwithstanding the subsequent amendment and restatement of the Original Certificate of Designation. (c) Dividends or Distributions on Common Stock. Holders of Series A Preferred Stock shall fully participate, on an as-converted basis, in any dividends declared and paid or distributions on Common Stock as if the shares of Series A Preferred Stock were converted into shares of Common Stock (as provided in Section 5) as of the record date for such dividend or distribution. Section 5. Optional Conversion. (a) Optional Conversion. At any time between January 22, 2026 and May 31, 2026, at the written election of the Majority Holders, acting on behalf of all Holders (with respect to all shares of Series A Preferred Stock then outstanding), and without the payment of additional consideration by the Holder(s), all, but not less than all, of the outstanding shares of Series A Preferred Stock shall be convertible into that number of fully paid and non-assessable shares of Common Stock, in the aggregate, equal to the Conversion Amount (as defined below), in accordance with the terms and conditions of this Section 5. (b) Mechanics of Conversion. (i) Notice of Conversion. In order for the Majority Holders (on behalf of all Holders) to voluntarily convert all, but not less than all, of the shares of Series A Preferred Stock into shares of Common Stock as set forth in Section 5(a), (A) the Majority Holders shall provide written notice to the Company's transfer agent at the office of the transfer agent for the Series A Preferred Stock (or at the principal office of the Company if the Company serves as its own transfer agent) that the Majority Holders elect to convert all, but not less than all, of the then-outstanding shares of Series A Preferred Stock and, if applicable, any event on which such conversion is contingent and (B) if any converting Holder's shares are certificated, such Holder shall surrender the certificate or certificates for such shares of Series A Preferred Stock (or, if such registered holder alleges that such certificate has been lost, stolen or destroyed, a lost certificate affidavit and agreement reasonably acceptable to the Company to indemnify the Company against any claim that may be made against the Company on account of the alleged loss, theft or destruction of such certificate), at the office of the transfer agent for the Series A Preferred Stock (or at the principal office of the Company if the Company serves as its own transfer agent). Such notice shall state such Holder's name and the names of the nominees

![](exhibit101-formofsubscri031.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;5 in which such Holder wishes the shares of Common Stock to be issued. If required by the Company, any certificates surrendered for conversion shall be endorsed or accompanied by a written instrument or instruments of transfer, in form satisfactory to the Company, duly executed by the registered Holder or his, her or its attorney duly authorized in writing. The close of business, Eastern Time, on the date of receipt by the transfer agent (or by the Company if the Company serves as its own transfer agent) of such notice and, if applicable, certificates (or lost certificate affidavit and agreement) shall be the time of conversion (the "Conversion Time"), and the shares of Common Stock issuable upon conversion of the specified shares shall be deemed to be outstanding of record as of such date. The Company shall, as soon as practicable after the Conversion Time, issue and deliver to the converting Holder or Holders, or to their nominees, a certificate or certificates for the number of full shares of Common Stock issuable upon such conversion in accordance with the provisions hereof and a certificate for the number (if any) of the shares of Series A Preferred Stock represented by the surrendered certificate that were not converted into Common Stock or, if such shares are uncertificated, register such shares in book-entry form. Delivery of the Common Stock upon conversion pursuant to Section 5(a) shall be deemed to fully satisfy and discharge any obligation with respect to accrued Dividend Accruals on such converted shares of Series A Preferred Stock as of the Conversion Time. (ii) Reservation of Shares. The Company shall at all times following receipt of the Requisite Stockholder Approvals and so long as any shares of Series A Preferred Stock remain outstanding, reserve and keep available out of its authorized but unissued capital stock, for the purpose of effecting the conversion of the Series A Preferred Stock, such number of its duly authorized shares of Common Stock as shall from time to time be sufficient to effect the conversion of all outstanding Series A Preferred Stock. If at any time following receipt of the Requisite Stockholder Approvals the number of authorized but unissued shares of Common Stock shall not be sufficient to effect the conversion of all then outstanding shares of the Series A Preferred Stock, the Company shall take such corporate action as may be necessary to increase its authorized but unissued shares of Common Stock to such number of shares as shall be sufficient for such purposes, including, without limitation, engaging in best efforts to obtain the requisite stockholder approval of any necessary amendment to the Certificate of Incorporation. (iii) Effect of Conversion. All shares of Series A Preferred Stock which shall have been surrendered for conversion as herein provided shall no longer be deemed to be outstanding and all rights with respect to such shares shall immediately cease and terminate at the Conversion Time, except the right of the Holders thereof to receive shares of Common Stock in exchange therefor. (iv) Taxes. The Company shall pay any and all issue and other similar taxes that may be payable in respect of any issuance or delivery of shares of Common Stock upon conversion of Series A Preferred Stock pursuant to this Section 5. The Company shall not, however, be required to pay any tax which may be payable in respect of any transfer involved in the issuance and delivery of shares of Common Stock in a name other than that in which the shares of Series A Preferred Stock so converted were registered, and no such issuance or delivery shall be made unless and until the person or entity requesting such issuance has paid to the Company the amount

(b) Procedural Requirements. All Holders of record of shares of Series A Preferred Stock shall be sent written notice of the Mandatory Conversion Time, if any, and the place designated for mandatory conversion of all such shares of Series A Preferred Stock pursuant to this Section 6. Such notice need not be sent in advance of the occurrence of the Mandatory Conversion Time. Upon receipt of such notice, each Holder of shares of Series A Preferred Stock being converted that holds such shares of Series A Preferred Stock in certificated form shall surrender his, her or its certificate or certificates for all such shares (or, if such Holder alleges that such certificate has been lost, stolen or destroyed, a lost certificate affidavit and agreement reasonably acceptable to the Company to indemnify the Company against any claim that may be made against the Company on account of the alleged loss, theft or destruction of such certificate), at the office of the transfer agent for the Series A Preferred Stock (or at the principal office of the Company if the Company serves as its own transfer agent). If so required by the Company, any certificates surrendered for conversion shall be endorsed or accompanied by a written instrument or instruments of transfer, in form satisfactory to the Company, duly executed by the registered Holder or his, her or its attorney duly authorized in writing. All rights with respect to the Series A Preferred Stock converted pursuant to this Section 6, including the rights, if any, to receive notices and vote (other than as a holder of Common Stock), will terminate at the Mandatory Conversion Time (notwithstanding the failure of the Holder or Holders thereof to surrender any certificates at or prior to such time), except only the rights of the Holders thereof, upon surrender of any certificate or certificates of such Holders (or lost certificate affidavit and agreement) therefor, to receive the items provided for in the next sentence of this Section 6(b).

WARRANT TO PURCHASE SHARES OF COMMON STOCK of LANZATECH GLOBAL, INC. Dated as of January 21, 2026 No. 1 WARRANT TO PURCHASE 7,800,000 SHARES OF COMMON STOCK This WARRANT ("Warrant") certifies that LanzaTech Global SPV, LLC, a Wyoming limited liability company, or its registered assigns, is the registered holder (the "Warrantholder") of a warrant, issued by LanzaTech Global, Inc., a Delaware corporation (the "Company"), to purchase the number of shares (the "Warrant Shares") of common stock of the Company, par value $0.0000001 per share (such stock, the "Common Stock"), as set forth above at an exercise price equal to $0.0000001 per share (as adjusted in accordance with this Warrant, the "Exercise Price"), which, subject to the satisfaction of the Conditions to Exercise, shall be exercisable until the Expiration Time, on the terms and subject to the conditions set forth in this Warrant. SECTION 1. Exercise Price. The Warrant evidenced hereby entitles the holder, upon proper exercise and payment of the applicable Exercise Price (including by Cashless Exercise), to receive from the Company, as adjusted as provided herein, 7,800,000 fully-paid, non-assessable shares of Common Stock. SECTION 2. Warrant Register. The Company shall register this Warrant upon records to be kept and properly maintained by the Company at its principal executive offices (the "Warrant Register") in the name of the record Warrantholder hereof from time to time.

2 SECTION 4. Transfers. (a) Subject to the provisions of Section 4(c), the Warrantholder may sell, assign, transfer, pledge or dispose of all or any portion of this Warrant at any time or from time to time without the prior approval of the Company. In connection with any transfer of all or any portion of this Warrant, the Warrantholder must provide an assignment form substantially in the form attached hereto as Exhibit A duly completed and executed by the Warrantholder or any such subsequent Warrantholder, as applicable, and the proposed transferee must consent in writing to be bound by the terms and conditions of this Warrant. Any transfer of all or any portion of this Warrant shall also be subject to the Securities Act and other applicable federal or state securities or blue sky laws. Upon any transfer of this Warrant, the Warrantholder shall be required to physically surrender this Warrant to the Company within two Trading Days of the date the Warrantholder delivers an assignment form to the Company assigning this Warrant and the Company shall execute and deliver a new Warrant or Warrants in the name of the assignee or assignees and in the denominations specified in such instrument of assignment, shall issue to the Warrantholder a new Warrant evidencing the portion of this Warrant, if any, not so assigned and this Warrant shall promptly be cancelled in accordance with Section 6, and the Company shall register any such transfer upon the Warrant Register. This Warrant or any portion thereof shall not be sold, assigned, transferred, pledged or disposed of in violation of the Securities Act, federal or state securities laws or the Company's Charter. (b) No service charge shall be made for any exchange or registration of transfer of this Warrant, but the Company may require payment of a sum sufficient to cover any stamp or other tax or other governmental charge that may be imposed on the Warrantholder in connection with any such exchange or registration of transfer. (c) This Warrant shall not be sold, exchanged or otherwise transferred in violation of the Securities Act or applicable state securities laws. The Warrantholder, by its acceptance of this Warrant, acknowledges and agrees that the Warrant (including any Warrant Shares issued upon exercise thereof) was issued pursuant to an exemption from the registration requirement of Section 5 of the Securities Act provided by Section 4(a)(2) of the Securities Act and such Warrantholder may not be able to sell or transfer any Warrant Shares in the absence of an effective registration statement under the Securities Act or an exemption from registration thereunder. This Warrant will not be subject to any restrictions on transfer other than those under applicable securities laws. SECTION 5. Duration and Exercise of Warrant. (a) This Warrant shall not be exercisable unless and until the date, if any, on which the Company consummates an Other Financing (collectively, the "Conditions to Exercise"). For the avoidance of doubt, this Warrant shall become void and of no value, and may not be exercised at any time after the Expiration Time. (b) (i) At any time after the Conditions to Exercise have been satisfied and prior to the termination of this Warrant pursuant to Section 18, the Warrantholder may exercise this Warrant by providing written notice of such exercise (the "Warrant Exercise Notice") to the Company at the address set forth in Section 14, which Warrant Exercise Notice shall be substantially in the form set forth in Exhibit B hereto, properly completed and executed by the Warrantholder, and shall be delivered no later than the Expiration Time; and (ii) if (A) the Conditions to Exercise are satisfied prior to the termination of this Warrant pursuant to Section 18 and (B) no Warrant Exercise Notice has been delivered, then, without the necessity of delivering the Warrant Exercise Notice, (x) each Warrant shall be deemed automatically exercised at the Exercise Time in accordance with Section 5(c) and (y) the Company shall deliver the Warrant Shares to the Warrantholder in accordance with Section 5(g).

![](exhibit102-amendedwarran003.jpg)

3 (c) Upon the exercise of this Warrant pursuant to Section 5(b), in lieu of paying the aggregate Exercise Price, the Warrantholder shall be deemed for all purposes hereunder to have authorized the Company to withhold from issuance a number of Warrant Shares issuable upon exercise of all Warrants being exercised by the Warrantholder at such time which, when multiplied by the Current Market Price of the Warrant Shares, is equal to the aggregate Exercise Price, and such withheld Warrant Shares shall no longer be issuable under this Warrant (a "Cashless Exercise"). (d) The formula for determining the number of Warrant Shares to be issued in a Cashless Exercise is as follows: X= (A-B) x C A Where: X = the number of Warrant Shares issuable upon exercise pursuant to subsection (b). A = the Current Market Price of a Warrant Share on the Trading Day immediately preceding the date upon which the Exercise Time occurs. B = the Exercise Price. C = the number of Warrant Shares as to which this Warrant is then being exercised including the withheld Warrant Shares. (e) The number of Warrant Shares to be issued upon such exercise will be determined by the Company using the formula set forth in Section 5(d). (f) Any exercise of this Warrant pursuant to the terms hereof shall be irrevocable and shall be deemed to constitute a binding agreement between the Warrantholder and the Company, enforceable in accordance with its terms. (g) As soon as practicable after the exercise of this Warrant as set forth in Section 5(b), the Company shall issue, or otherwise deliver, or cause to be issued or delivered, in authorized denominations to or upon the order of the Warrantholder, a book-entry interest in the Warrant Shares registered on the books of the Company's transfer agent. Such Warrant Shares shall be deemed to have been issued as of the Exercise Time. SECTION 6. Cancellation of Warrant. Upon the Expiration Time, or if the Company shall purchase or otherwise acquire the Warrant, the Warrant shall be cancelled by the Company and retired. The Company shall cancel any Warrant surrendered for exchange, substitution, transfer or exercise in whole or in part. SECTION 7. Mutilated or Missing Warrant. If this Warrant is mutilated, lost, stolen or destroyed, the Company shall issue and deliver, in exchange and substitution for and upon cancellation of the mutilated Warrant, or in lieu of and substitution for the Warrant lost, stolen or destroyed, a new Warrant of like tenor and representing the right to purchase an equivalent number of Warrant Shares, but only (a) upon receipt of evidence reasonably satisfactory to the Company of the loss, theft or destruction of such Warrant; (b) upon receipt of an open penalty surety bond holding the Company harmless, if requested by the Company and satisfactory to it; and (c) absent notice to the Company that such Warrant has been acquired by a bona fide purchaser. Applicants for such substitute Warrant shall also comply with such other reasonable regulations and pay such other reasonable charges as the Company may prescribe and as required by Section 8-405 of the Uniform Commercial Code as in effect in the State of New York.

5 by a fraction, (i) the numerator of which is the Exercise Price in effect immediately prior to such adjustment and (ii) the denominator of which is the Exercise Price in effect immediately following such adjustment. (c) No adjustment to the Exercise Price or number of Warrant Shares for this Warrant shall be required hereunder unless such adjustment together with other adjustments carried forward as provided below, would result in an increase or decrease of at least 1% of the applicable Exercise Price or Warrant Shares. No adjustment need be made for a change in the par value of the shares of Common Stock or any other Common Stock Equivalents. All calculations under this Section 9 shall be made to the nearest one- one thousandth (1/1,000th) of one cent ($0.00001) or to the nearest one-one thousandth (1/1,000th) of a share, as the case may be. In no event will the Company adjust the Exercise Price to the extent that the adjustment would reduce the Exercise Price below the par value per share of Common Stock. In such case, the number of Warrant Shares shall be adjusted as if the Exercise Price had been adjusted as otherwise set forth in this Section 9(c) and each Warrant Share shall be exercisable for the par value per Warrant Share. SECTION 10. No Fractional Shares. The Company shall not be required to issue a Warrant to purchase fractions of Warrant Shares, or to issue fractions of Warrant Shares upon exercise of the Warrant, or to distribute certificates which evidence fractional Warrant Shares and no Cash shall be distributed in lieu of such fractional shares or rights. If more than one Warrant shall be deemed exercised by the same Warrantholder, the number of full Warrant Shares which shall be issuable upon the exercise thereof shall be computed on the basis of the aggregate number of Warrant Shares purchasable on exercise of such Warrants. If any fraction of a share would, except for the provisions of this Section 10, be issuable on the exercise of the Warrant (or specified portion thereof), as applicable, such share shall be rounded to the next higher whole number. SECTION 11. Redemption. The Warrant shall not be redeemable by the Company or any other Person. SECTION 12. Notices to the Warrantholder. Upon any adjustment of the number of Warrant Shares purchasable upon exercise of this Warrant, the Company, within 10 Business Days thereafter, shall give written notice thereof to the Warrantholder at its address appearing on the Warrant Register. Where appropriate, such notice may be given in advance and included as a part of the notice required to be mailed under the other provisions of this Section 12. If (i) the Company proposes to take any action that would require an adjustment pursuant to Section 9 or (ii) there shall be a dissolution, liquidation or winding-up of the Company (other than in connection with a consolidation, merger or sale of all or substantially all of its property, assets and business as an entirety), then the Company shall cause written notice of such event to be given to the Warrantholder at its address appearing on the Warrant Register, such giving of notice to be completed at least 10 Business Days prior to the effective date of such action (or the applicable Record Date for such action if earlier). Such notice shall specify the proposed effective date of such action and, if applicable, the Record Date and the material terms of such action. The failure to give the notice required by this Section 12 or any defect therein shall not affect the legality or validity of any action, distribution, right, warrant, dissolution, liquidation or winding up or the vote upon or any other action taken in connection therewith. SECTION 13. Warrantholder Not Deemed a Stockholder by Virtue of this Warrant. Nothing contained in this Warrant shall be construed as conferring upon the Warrantholder the right to vote or to receive dividends or to participate in any transaction that would give rise to an adjustment under Section 9 or to consent or to receive notice as a stockholder in respect of the meetings of stockholders or for the election of directors of the Company or any other matter, or any rights whatsoever as a stockholder of the Company.

In addition, the consent of each Warrantholder affected shall be required for any amendment pursuant to which the Exercise Price would be increased or the number of Warrant Shares issuable upon exercise of Warrants would be decreased (other than pursuant to adjustments provided in this Warrant).
