**CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS**

This Quarterly Report on Form 10-Q (this "Form 10-Q"), including, without limitation, statements under the headings "Management's Discussion and Analysis of Financial Condition and Results of Operations," includes forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, (the "Securities Act") and Section 21E of the Securities Exchange Act of 1934, as amended, (the "Exchange Act"). Generally, statements that are not historical facts, including statements concerning Momentus Inc.'s (the "Company," "Momentus," "we," "us," or "our") possible or assumed future actions, business strategies, events, or results of operations, are forward-looking statements. These forward-looking statements can be identified by the use of forward-looking terminology, including the words "believes," "estimates," "anticipates," "expects," "intends," "plans," "may," "will," "potential," "projects," "predicts," "continue," or "should," or, in each case, their negative or other variations or comparable terminology, but the absence of these words does not mean that a statement is not forward-looking. There can be no assurance that actual results will not materially differ from expectations.

The forward-looking statements contained in this Form 10-Q are based on our current expectations and beliefs concerning future developments and their potential effects on us. Future developments affecting us may not be those that we have anticipated. These forward-looking statements involve a number of risks, uncertainties (some of which are beyond our control) and other assumptions that may cause actual results or performance to be materially different from those expressed or implied by these forward-looking statements. These risks and uncertainties include, without limitation, the ability of the Company to raise additional capital to finance its longer-term business plan; the ability of the Company to obtain licenses and government approvals for its missions, which are essential to its operations; the ability of the Company to effectively market and sell satellites and satellite components; the ability to market and sell transportation services and planned in-orbit services; the ability of the Company to protect its intellectual property and trade secrets; the development of markets for small satellites and satellite transport and in-orbit services; the ability of the Company to develop, test and validate its technology, including its water plasma propulsion technology and Tape Spring Solar Array; delays or impediments that the Company may face in the development, manufacture and deployment of next generation satellite transport systems; the ability of the Company to convert backlog or inbound inquiries into revenue; changes in applicable laws or regulations and extensive and evolving government regulations that impact operations and business, including export control license requirements; the ability to attract or maintain a qualified workforce with the required security clearances and requisite skills; level of product service or product or launch failures or delays that could lead customers to use competitors' services; investigations, claims, disputes, enforcement actions, litigation and/or other regulatory or legal proceedings; the possibility that the Company may be adversely affected by other economic, business, and/or competitive factors; and/or other risks and uncertainties described under Part II, Item 1A: "*Risk Factors*," in this Form 10-Q and under Part I, Item 1A in our Annual Report on Form 10-K filed with the U.S. Securities and Exchange Commission (the

------

<u>[Tables of Contents](#if15138d1252741479228fb3609acb72e_247)</u>

"SEC") on March 31, 2026. Should one or more of these risks or uncertainties materialize, or should any of our assumptions prove incorrect, actual results may vary in material respects from those projected in these forward-looking statements. We undertake no obligation to update or revise any forward-looking statements, whether as a result of new information, future events, or otherwise, except as may be required under applicable securities laws. These risks and others described under Part II, Item 1A: "Risk Factors," in this Form 10-Q and under Part I, Item 1A in our Annual Report on Form 10-K filed with the SEC on March 31, 2026, may not be exhaustive.

By their nature, forward-looking statements involve risks and uncertainties because they relate to events and depend on circumstances that may or may not occur in the future. We caution you that forward-looking statements are not guarantees of future performance and that our actual results of operations, financial condition and liquidity, and developments in the industry in which we operate may differ materially from those made in or suggested by the forward-looking statements contained in this Form 10-Q. These statements are inherently uncertain and investors are cautioned not to unduly rely upon these statements. In addition, even if our results or operations, financial condition and liquidity, and developments in the industry in which we operate are consistent with the forward-looking statements contained in this Form 10-Q, those results or developments may not be indicative of results or developments in subsequent periods.

**MOMENTUS INC.**

**NOTES TO THE CONDENSED CONSOLIDATED INTERIM FINANCIAL STATEMENTS**

**Note 1. Nature of Operations**

***The Company***

Momentus Inc. (together with its consolidated subsidiaries "Momentus" or the "Company") is a U.S. commercial space company that offers satellites, satellite buses, satellite technologies and components, and space infrastructure services, including in-space transportation, hosted payloads and in-orbit services.

Momentus has launched five missions to date, deployed 17 customer satellites, and provided hosted payload services. Four of these missions involved operation of the Vigoride Orbital Service Vehicle ("OSV") in orbit. During these four Vigoride missions, the system and technology were tested repeatedly. Improvements based on lessons learned during these missions were rapidly incorporated. As a result of these four missions, the Vigoride OSV has been successfully demonstrated in space and accumulated significant flight heritage.

The Company launched its latest OSV, Vigoride 7, on March 30, 2026 to low Earth orbit ("LEO") with 10 payloads During this mission, which is expected to last several months, the Company is scheduled to provide hosted payload services to a range of U.S. Government customers with payloads aboard, including the Defense Advanced Research Projects Agency ("DARPA"), SpaceWERX, which is the innovation organization of the U.S. Space Force, the U.S. Air Force Research Laboratory, the National Aeronautics and Space Administration ("NASA"), as well as commercial customers.

In addition to the Vigoride OSV, Momentus is also offering its M-1000 satellite bus which has substantial commonality with Vigoride. With a growing demand for satellite bus services, Momentus is positioned to advance its hardware and flight-proven technology for this market. The M-1000 bus is a flexible option to meet various mission requirements. Innovations to improve sensor capability, maneuverability, increased power, and lower costs are integrated into the product. Momentus believes it can manufacture satellite buses like the M-1000 at a rapid and scalable pace.

***Capital Resources and Recent Financing Transactions***

During the three months ended March 31, 2026, the Company received Net cash provided by financing activities of approximately $16.7 million primarily from sales of Class A common stock. Since March 31, 2026, the Company also completed a private placement of securities for gross proceeds of $5.0 million and certain convertible notes were fully converted into shares of Class A common stock. See Notes 9 and 16 for additional details. These proceeds, combined with service revenue received during the quarter ended March 31, 2026, have improved the liquidity and financial position of the Company over December 31, 2025. The Company also raised approximately $10.5 million from sales of Class A common stock in May 2026.

In prior periods, the Company disclosed that conditions and events raised substantial doubt regarding its ability to continue as a going concern. Management believes that, as a result of the financings and related transactions completed since December 31, 2025, substantial doubt no longer exists.

Based on the Company's current cash position, expected operating plan and forecasted liquidity needs, management has concluded that the Company has sufficient resources to fund operations and meet its obligations for at least the twelve-month period following the issuance date of these condensed consolidated interim financial statements.

The accompanying condensed consolidated interim financial statements have been prepared assuming that the Company will continue as a going concern. The going concern basis of presentation assumes that the Company will continue in operation one year after the date these condensed consolidated interim 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's forecasts and operating plans are subject to risks and uncertainties as discussed above under *Cautionary Note Regarding Forward-Looking Statements*, and actual results could differ from management's expectations.

**NOTES TO THE CONDENSED CONSOLIDATED INTERIM FINANCIAL STATEMENTS**

**Note 1. Nature of Operations** (cont.)

***Reverse Stock Splits***

Effective December 17, 2025, the Company's stockholders approved a 1-for-17.85 reverse stock split of the Company's Class A common stock. As a result of the reverse stock split, every 17.85 shares of Class A common stock issued and outstanding on December 17, 2025, were automatically combined into one share of Class A common stock. Any fractional shares resulting from the reverse stock split were rounded up to the next nearest whole share of Class A common stock. The reverse stock split did not affect the stated par value of the Class A common stock nor did it change the total number of the Company's authorized shares of Class A common stock. Both the Company's Class B common stock and Series A preferred stock were not affected by the reverse stock split.

Also on the effective date of each reverse stock split, all options, warrants, and other convertible securities of the Company outstanding immediately prior to the reverse stock split were adjusted by dividing the number of shares of Class A common stock into which the options, warrants, and other convertible securities are exercisable or convertible by the factor applied in the reverse stock split, and multiplying the exercise or conversion price thereof by the same amount, all in accordance with the terms of the plans, agreements, or arrangements governing such options, warrants, and other convertible securities and subject to rounding to the nearest whole share. Such proportional adjustments were also made to the number of shares and restricted stock units ("RSUs") issued and issuable under the Company's equity compensation plans.

The Company has retroactively adjusted all periods presented for the effects of the December 2025 1-for-17.85 reverse stock split. See Note 9 for additional information.

**Note 2. Summary of Significant Accounting Policies**

***Consolidated Interim Financial Information***

The accompanying condensed consolidated interim financial statements have been prepared in accordance with United States of America Generally Accepted Accounting Principles ("GAAP") and pursuant to the rules and regulations of the SEC. Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. The consolidated balance sheet as of December 31, 2025 was derived from the Company's consolidated audited financial statements but does not include all disclosures required by GAAP for consolidated audited financial statements. Any reference in these notes to applicable guidance is meant to refer to the authoritative GAAP as found in the Accounting Standards Codification ("ASC") and Accounting Standards Update ("ASU") of the Financial Accounting Standards Board (the "FASB").

The unaudited condensed consolidated interim financial statements have been prepared on the same basis as the audited consolidated financial statements. The accompanying condensed consolidated interim financial statements contain all adjustments that are necessary to present fairly the Company's financial position as of March 31, 2026, and December 31, 2025, the results of operations for the three months ended March 31, 2026 and 2025, the statements of changes in stockholders' equity (deficit) for the three months ended March 31, 2026 and 2025, and cash flows for the three months ended March 31, 2026 and 2025. Such adjustments are of a normal and recurring nature. The results for the three months ended March 31, 2026, are not necessarily indicative of the results for the year ending December 31, 2026, or for any future period. These condensed consolidated interim financial statements should be read in conjunction with the consolidated audited financial statements as of and for the years ended December 31, 2025 and 2024, filed with the SEC in our Annual Report on Form 10-K filed by the Company on March 31, 2026.

***Principles of Consolidation*** 

The condensed consolidated interim financial statements include the accounts of the Company and its subsidiaries. All intercompany transactions and balances have been eliminated upon consolidation.

***Use of Estimates***

The preparation of condensed consolidated interim financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts in the condensed consolidated interim financial statements and accompanying notes. Management bases its estimates on historical experience and

<u>[Tables of Contents](#if15138d1252741479228fb3609acb72e_247)</u>

**MOMENTUS INC.**

**NOTES TO THE CONDENSED CONSOLIDATED INTERIM FINANCIAL STATEMENTS**

**Note 2. Summary of Significant Accounting Policies** (cont.)

on various other factors it believes to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities. Accordingly, actual results could differ from those estimates. Significant estimates inherent in the preparation of the condensed consolidated interim financial statements include, but are not limited to, the timing of revenue recognition, accounting for useful lives of property, machinery and equipment, net, intangible assets, net, accrued liabilities, leases, income taxes including deferred tax assets and liabilities, impairment valuation, stock-based compensation, warrant liabilities, and litigation contingencies.

***Cash and Cash Equivalents***

Cash and cash equivalents consist of cash on hand, cash in bank with no restrictions, as well as highly liquid investments which are unrestricted as to withdrawal or use, and which have original maturities of three months or less when initially purchased.

The Company places its cash in the bank, which may at times be in excess of the Federal Deposit Insurance Corporation ("FDIC") insurance limits of $250,000 per depositor, with high credit quality financial institutions and attempts to limit the amount of credit exposure with any one institution.

***Restricted Cash***

Restricted cash primarily represents cash deposited as collateral for the Company's credit card program. As of March 31, 2026 and 2025, the Company maintained restricted cash of $0.1 million and $0.1 million, respectively.

***Accounts Receivable***

Accounts receivable as of March 31, 2026, represent amounts primarily due from NASA for engineering services performed. Accounts Receivable are stated at invoice value less estimated allowances for credit losses. Allowances are recorded based on the Company's assessment of various factors, such as: historical experience, credit quality of its customers, aging of the accounts receivable balances, economic conditions, and other factors that may affect a customer's ability to pay. The allowance for credit losses as of March 31, 2026 and 2025, was zero.

***Deferred Fulfillment and Prepaid Launch Costs***

The Company prepays for certain launch costs to third-party providers that will carry the transport vehicle to orbit. Prepaid costs allocated to the delivery of a customers' payload are classified as deferred fulfillment costs and prepaid costs allocated to our payload are classified as prepaid launch costs. All deferred fulfillment and prepaid launch costs are recognized as cost of revenue upon delivery of the related payloads.

As of March 31, 2026 and 2025, the Company had deferred fulfillment and prepaid launch costs of $2.2 million and $6.3 million, respectively, with $1.0 million and $5.1 million recorded within prepaids and other current assets, respectively, and $1.2 million and $1.2 million recorded within other non-current assets in our condensed consolidated balance sheets, respectively.

***Property, Machinery and Equipment***

Property, machinery and equipment are stated at cost less accumulated depreciation. Depreciation is generally recorded using the straight-line method over the estimated useful lives of the respective assets. The estimated useful lives of fixed assets by asset category are described below:

---

| | |
|:---|:---|
| **Fixed Assets** | **Estimated Useful Life** |
| Computer equipment | Three years |
| Furniture and fixtures | Five years |
| Leasehold improvements | Lesser of estimated useful life or remaining lease term (one year to seven years) |
| Machinery and equipment | Seven years |

---

Costs of maintenance or repairs that do not extend the lives of the respective assets are charged to expenses as incurred.

**MOMENTUS INC.**

**NOTES TO THE CONDENSED CONSOLIDATED INTERIM FINANCIAL STATEMENTS**

**Note 2. Summary of Significant Accounting Policies** (cont.)

***Intangible Assets***

Intangible assets, which consist of patents, are considered long-lived assets and are reported at cost less accumulated amortization and accumulated impairment loss, if any. Amortization is recognized on a straight-line basis over 10 years for patents, which is the estimated useful lives of the intangible assets.

In accordance with ASC Sub-Topic 350-40, *Intangibles*, the Company presents capitalized implementation costs for cloud computing arrangements within prepaid and other current assets, and other non-current assets to properly present the capitalized costs with their related subscription fees.

***Loss Contingencies***

The Company estimates loss contingencies in accordance with ASC Sub-Topic 450-20, *Loss Contingencies* ("ASC 450-20"), which states that a loss contingency shall be accrued by a charge to income if both of the following conditions are met: (i) information available before the condensed consolidated interim financial statements are issued or are available to be issued indicates that it is probable that a liability had been incurred at the date of the condensed consolidated interim financial statements and (ii) the amount of loss can be reasonably estimated. We regularly evaluate current information available to us to determine whether such accruals should be adjusted and whether new accruals are required. Refer to Note 12 for additional information.

***Revenue Recognition***

The Company enters into short-term contracts for 'last-mile' satellite and cargo delivery (transportation service), payload hosting and in-orbit servicing options with customers that are primarily in the aerospace industry. For its transportation service arrangements, the Company has a performance obligation of delivering the customers' payload to its designated orbit and recognizes revenue (along with any other fees that have been paid) at a point in time, upon satisfaction of this performance obligation. Additionally, for its in-orbit service arrangements, the Company provides a multitude of services during the mission to its customers. The Company recognizes revenue for these in-orbit services ratably over time on a straight-line basis. The Company also enters into contracts to perform analysis and provide engineering services to U.S. government organizations.

The Company accounts for customer contracts in accordance with ASC Topic 606, *Revenue from Contracts with Customers* ("ASC Topic 606"), which includes the following five-step model:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Identification of the contract, or contracts, with a customer.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Identification of the performance obligations in the contract.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Determination of the transaction price.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Allocation of the transaction price to the performance obligations in the contract.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Recognition of revenue when, or as, the Company satisfies a performance obligation.

The Company estimates variable consideration at the most likely amount, which is included in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur. While the Company's standard contracts do not contain refund or recourse provisions that enable its customers to recover any non-refundable fees that have been paid, the Company may issue full or partial refunds, or concessions on future services to customers on a case-by-case basis as necessary to preserve and foster future business relationships and customer goodwill. Contracts to provide engineering services to U.S. government organizations generally have set payments tied to each milestone. When a milestone is achieved, the Company submits the completed service for approval, submits invoices to the government site, and collects on that completed milestone. During the three months ended March 31, 2026 and 2025, the Company recorded $2.7 million and $0.2 million, respectively, of revenue from the U.S. government.

As part of its contracts with customers, the Company collects up-front non-refundable deposits prior to launch. As of March 31, 2026 and 2025, the Company had customer deposit balances of $0.5 million and $4.2 million, respectively, related to signed contracts with customers, including firm orders and options (some of which have already been exercised by customers). These deposits are recorded as contract liabilities in the Company's

**Note 2. Summary of Significant Accounting Policies** (cont.)

condensed consolidated balance sheets. Included in the collected amount as of March 31, 2026 and 2025, are $0.1 million and $0.1 million, respectively, of non-current deposits.

During the three months ended March 31, 2026, the Company recognized $3.2 million of revenue primarily due to engineering services performed for NASA and hosted payload services. Of the $3.2 million of revenue recognized, $0.6 million was derived from the December 31, 2025, contract liability balance. During the three months ended March 31, 2025, the Company recognized $0.3 million of revenue due to engineering services performed for the DARPA Novel Orbital and Moon Manufacturing, Materials, and Mass-efficient Design ("NOM4D") and DARPA Bringing Classified Innovation to Defense and Government Systems ("BRIDGES") programs, and forfeited customer deposits primarily related to expired options. Of the $0.3 million of revenue recognized, $0.1 million was derived from the December 31, 2024, contract liability balance.

The disaggregation of revenue by type is as follows:

---

| | | |
|:---|:---|:---|
| | **Three Months Ended<br>March 31,** | **Three Months Ended<br>March 31,** |
| *(in thousands)* | **2026** | **2025** |
| Hosted payload services | $1618 | $— |
| Forfeited customer deposits |  | 87 |
| Engineering project services | 1597 | 235 |
| &nbsp;&nbsp;&nbsp;&nbsp;Total revenue | $3215 | $322 |

---

***Fair Value Measurement***

The Company uses valuation approaches that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible. A three-tiered hierarchy is established as a basis for considering such assumptions and for inputs used in the valuation methodologies in measuring fair value. This hierarchy requires that the Company use observable market data, when available, and minimize the use of unobservable inputs when determining fair value:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Level 1, observable inputs such as quoted prices in active markets;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Level 2, inputs other than the quoted prices in active markets that are observable either directly or indirectly; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Level 3, unobservable inputs in which there is little or no market data, which requires that the Company develop its own assumptions.

The fair values of cash and cash equivalents, accounts payable, and certain prepaid and other current assets and accrued expenses approximate carrying values due to the short-term maturities of these instruments which fall with Level 1 of the fair value hierarchy. The carrying value of certain other non-current assets and liabilities approximates fair value. The Company had no Level 2 inputs for the three months ended March 31, 2026 and 2025.

As of March 31, 2026, the Company does not have any assets measured at fair value on a recurring basis, other than the Credit Provision Derivative (see Note 9 for additional detail). The Credit Provision Derivative is measured at fair value under ASC Topic 815 and is classified within Level 3 of the fair value hierarchy. The Company estimated the fair value of derivative asset based on the expected underutilization payment to be received during 2026.

The change in fair value of the Credit Provision Derivative asset subject to recurring remeasurement was as follows:

---

| | |
|:---|:---|
| *(in thousands)* |  |
| Balance, December 31, 2025 | $164 |
| &nbsp;&nbsp;&nbsp;&nbsp;Settlement | (146) |
| Balance, March 31, 2026 | $18 |

---

As of March 31, 2026, the Company has the following liabilities measured at fair value on a recurring basis:

------

**MOMENTUS INC.**

**NOTES TO THE CONDENSED CONSOLIDATED INTERIM FINANCIAL STATEMENTS**

**Note 2. Summary of Significant Accounting Policies** (cont.)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Certain of the Company's warrants are recorded as a derivative liability pursuant to ASC Topic 815, *Derivatives and Hedging* ("ASC Topic 815"), and are classified within Level 3 of the fair value hierarchy as the Company is using the BSM option pricing model.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The May 2025 Convertible Note, issued for non-employee services, is classified as a liability under ASC Topic 718 and measured at fair value. The May 2025 Convertible Note is classified within Level 3 of the fair value hierarchy as the Company is using a convertible bond pricing model to calculate fair value. Key assumptions used to determine the fair value of the May 2025 Convertible Note were as follows:

---

| | | |
|:---|:---|:---|
| | **January 9,<br>2026** | **December 31,<br>2025** |
| Expected term (years) | 0.84 | 0.96 |
| Stock price | $12.46 | $4.87 |
| Volatility | 45.00% | 45.00% |
| Risk-free rate | 3.54% | 3.49% |
| Dividend yield | —% | —% |

---

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The AIR Warrants are classified as a liability under ASC Topic 480 and measured at fair value. The AIR Warrants are classified within Level 3 of the fair value hierarchy because their fair value is determined using an option pricing model that incorporates significant unobservable inputs, including expected stock price volatility and the discount rate on the underlying junior convertible notes. The Company calculates the fair value by weighting two different approaches. As of March 31, 2026, the AIR Warrants remained significantly out-of-the-money and the Company determined the fair value of the AIR Warrants was zero, consistent with the December 31, 2025 measurement. Accordingly, the Company did not update the option pricing model assumptions during the quarter. Key assumptions used to determine the fair value of the AIR Warrants as of December 31, 2025, were as follows:

---

| | | |
|:---|:---|:---|
| | **Underlying Investor Warrants (BSM)** | **Junior Convertible Notes** |
| Expected term (years) | 5.00 | 0.92 |
| Stock price | $4.87 | $4.87 |
| Volatility | 87.50% | 45.00% |
| Risk-free rate | 3.73% | 3.50% |
| Dividend yield | —% | —% |
| Discount rate on the note | 78.64% | 78.64% |
| Exercise price of AIR Warrants (millions) | $3.7 | $3.7 |

---

The primary significant unobservable input used in the valuation of the warrants and convertible notes is expected stock price volatility. Expected stock price volatility is based on the actual historical volatility of a group of comparable publicly traded companies observed over a historical period equal to the expected remaining life of the instruments. The risk-free interest rate is based on the U.S. Treasury yield curve in effect on the date of valuation equal to the remaining expected life of the instruments. The expected term was based on the maturity of the instruments, which is 5 years for Class A common stock warrants and 1.5 years for Class B common stock warrants. The dividend yield percentage is zero because the Company does not currently pay dividends, nor does it intend to do so during the expected term of the instruments. There were no transfers between levels of input during the three months ended March 31, 2026 and 2025.

***Derivative Instruments***

The Company accounts for derivative instruments in accordance with ASC Topic 815. The Company does not designate any derivative instruments as hedges of cash flow, fair value, or foreign currency exposures, and therefore does not apply hedge accounting. The Company's derivative instruments consist of (i) freestanding warrants that do not qualify for equity classification under ASC Topic 815 or that meet the definition of a liability under ASC Topic 480, (ii) embedded features within the Company's convertible debt instruments that require bifurcation and separate recognition as derivatives, and (iii) other freestanding contracts that meet the definition of a derivative. Derivative instruments are initially and subsequently measured at fair value, with changes in fair value recognized in the condensed consolidated statements of operations. The classification of each derivative as an asset or liability, and as current or non-current, is based on the expected timing of settlement. Fair value is determined using the BSM option pricing model, convertible bond pricing models, or other appropriate valuation techniques, depending on the nature of the instrument. See Note 8 for embedded derivatives associated with the Company's convertible debt, and Note 9 for the Company's outstanding warrants.

***Warrant Liability***

The Company evaluates each warrant on issuance to determine whether it should be classified as equity or as a liability. Warrants that meet the definition of a derivative and do not qualify for the derivative scope exception under ASC Topic 815 are classified as derivative liabilities. Warrants that embody an unconditional obligation to transfer assets, or a conditional obligation to issue a variable number of shares, are classified as liabilities under ASC Topic 480 and are initially and subsequently measured at fair value, with changes in fair value recognized in the condensed consolidated statements of operations. Significant unobservable inputs in the valuation of liability-classified warrants include expected volatility and, for certain warrants, the discount rate on the underlying instruments, resulting in Level 3 classification within the fair value hierarchy. Liability-classified warrants are presented as non-current, as their liquidation is not reasonably expected to require the use of current assets or the creation of current liabilities. Upon exercise, the fair value of the warrant liability at the exercise date is reclassified to additional paid-in capital within the condensed consolidated statements of stockholders' equity (deficit). See Note 9 for further discussion of the Company's outstanding warrants.

***Equity Classified Warrants***

Subsequent to the Business Combination, the Company has issued warrants in conjunction with various securities purchase agreements and borrowings (see Note 8 and Note 9 for additional information). The warrants are freestanding equity-linked instruments that meet the indexation and equity classification criteria of ASC Sub-Topic 815-40.

The grant-date fair value of these warrants is recorded in additional paid-in capital on the condensed consolidated balance sheets. The fair value of the warrants are measured using the BSM option pricing model on the grant date.

***Modification of Equity Classified Warrants***

A change in the terms or conditions of a warrant is accounted for as a modification. For a warrant modification accounted for under ASC Topic 815, the effect of a modification shall be measured as the difference between the fair value of the modified warrant and the fair value of the original warrant immediately before its terms are modified, with each measured on the modification date. The accounting for incremental fair value of the modified warrants over the original warrants is based on the specific facts and circumstances related to the modification. When a modification is directly attributable to an equity offering, the incremental change in fair value of the

**Note 2. Summary of Significant Accounting Policies** (cont.)

warrants is accounted for as an equity issuance cost. When a modification is directly attributable to a debt offering, the incremental change in fair value of the warrants is accounted for as a debt discount or debt issuance cost. For all other modifications, the incremental change in fair value is recognized as a deemed dividend.

***Convertible Instruments***

The Company evaluates its convertible debt issuances to determine if those contracts or embedded components of those contracts qualify as derivatives requiring separate recognition in the Company's financial statements. Entities must consider whether to classify contracts that may be settled in the Company's own stock, such as warrants, as equity of the entity or as an asset or liability. If an event that is not within the entity's control could require net cash settlement, then the contract should be classified as an asset or a liability rather than as equity. Convertible instruments issued for non-employee services, such as the May 2025 Convertible Note, are classified as liabilities under ASC Topic 718 if cash settlement is possible, measured at fair value each reporting period with changes in fair value recognized in operating expenses (see Note 8).

If the embedded conversion options do not require bifurcation, the Company then evaluates for the existence of a beneficial conversion feature by comparing the fair value of the Company's underlying stock as of the commitment date to the effective conversion price of the instrument (the intrinsic value).

Debt discounts under these arrangements are amortized over the term of the related debt to their stated date of redemption and are classified in interest expense in the condensed consolidated statements of operations. For liability-classified convertible instruments under ASC Topic 718, no debt discount is recorded, as fair value remeasurement captures all value changes.

Amendments to convertible instruments are evaluated as to whether they should be accounted for as a modification of the original instrument with no change to the accounting or, if the terms are substantially changed, as an extinguishment of the original instrument and the issuance of a new instrument.

***Fair Value Option for Convertible Debt***

The Company elected the fair value option ("FVO") for recognition of its convertible debt issued to J.J. Astor & Co., as permitted under ASC Topic 825, *Financial Instruments* (see discussion of the May 2025 Loan in Note 8). Under the FVO, the Company recognizes the convertible debt at fair value with changes in fair value recognized in earnings. The FVO may be applied instrument by instrument, but it is irrevocable. As a result of applying the FVO, any direct costs and fees related to the convertible debt is recognized in operating expense in the consolidated statements of operations as incurred and not deferred. Changes in fair value of the convertible debt are recognized as a separate line in the consolidated statements of operations and comprehensive loss.

***Equity Issuance Costs***

The Company incurs costs related to the issuance of equity securities. These costs are initially recorded as a prepaid asset under ASC Topic 340 and reclassified to additional paid-in capital as the related equity is earned through service delivery, or amortized to expense, typically research and development, based on the service period or delivery pattern.

***Basic and Diluted Loss Per Share***

Net loss per share is provided in accordance with ASC Sub-Topic 260-10, *Earnings per Share*. Basic net loss per share is computed by dividing losses by the weighted average number of common shares outstanding during the period. Diluted loss per share gives effect to all dilutive potential common shares outstanding during the period. Diluted loss per share excludes all potential common shares if their effect is anti-dilutive. See Note 11 for additional information.

***Impairment of Long-lived Assets***

The Company evaluates the carrying value of long-lived assets, which includes intangible assets, on an annual basis, or more frequently whenever circumstances indicate a long-lived asset may be impaired. When indicators of impairment exist, the Company estimates future undiscounted cash flows attributable to such assets. In the event cash flows are not expected to be sufficient to recover the recorded value of the assets, the assets are written down to

**Note 2. Summary of Significant Accounting Policies** (cont.)

their estimated fair value. During the three months ended March 31, 2026 and 2025, there were no impairments of long-lived assets. See Note 4 and Note 5 for additional information.

***Stock-based Compensation***

The Company has a stock incentive plan under which equity awards are granted to employees, directors, and consultants. The Company also issues equity or liability instruments, such as convertible notes, to non-employees for services under ASC Topic 718, which are measured at fair value at issuance and, for liability-classified instruments, remeasured each reporting period with changes in fair value recognized in operating expenses. All stock-based payments are recognized in the condensed consolidated interim financial statements based on their respective grant date fair values.

RSU fair value is based on our closing stock price on the day of the grant. Stock option fair value is determined using the BSM option pricing model. The model requires management to make a number of assumptions, including expected volatility of the Company's stock, expected life of the option, risk-free interest rate, and expected dividends. For non-employee awards, such as the May 2025 Convertible Note and shares issued in relation to the VLD MSA (defined in Note 9), fair value is determined using valuation models (e.g., Black-Scholes or similar) with unobservable inputs like volatility and discount rates, and liability-classified awards are remeasured until settlement (see Note 8). Employee Stock Purchase Plan ("ESPP") compensation fair value is also determined using the BSM option pricing model, using a six-month expected term to conform with the six month ESPP offering period.

The grant-date fair value of equity awards is expensed over the related service period which is typically the vesting period, and expense is only recognized for awards that are expected to vest. The Company accounts for forfeitures as they occur.

***401(k) Plan***

The Company has a 401(k) plan that it offers to its full-time employees. The Company did not contribute to the plan during the three months ended March 31, 2026 and 2025.

***Research and Development Costs***

Research and development costs are expensed as incurred. Research and development costs include activities to develop existing and future technologies for the Company's vehicles. Research and development activities include basic research, applied research, design, development, and related test program activities. Costs incurred for developing our vehicles primarily include equipment and labor hours (both internal and subcontractors).

Nonrefundable advance payments for goods or services that will be used or rendered for future research and development activities related to an executory contractual arrangement are deferred and capitalized. These advance payments are recognized as an expense as the related goods are delivered or services performed. When the related goods are no longer expected to be delivered or services rendered, the capitalized advance payment is charged to expense.

***Leases***

The Company determines if an arrangement contains a lease at inception based on whether there is an identified property, plant or equipment and whether the Company controls the use of the identified asset throughout the period of use.

Operating leases are included in the accompanying condensed consolidated balance sheets. Operating lease right-of-use ("ROU") assets represent the Company's right to use an underlying asset for the lease term. Lease liabilities represent the Company's obligation to make lease payments arising from the lease and are included in current and non-current liabilities. Operating lease ROU assets and lease liabilities are recognized at the lease inception date based on the present value of lease payments over the lease term discounted based on the more readily determinable of (i) the rate implicit in the lease or (ii) the Company's incremental borrowing rate (which is the estimated rate the Company would be required to pay for a collateralized borrowing equal to the total lease payments over the term of the lease). Because the Company's operating leases generally do not provide an implicit rate, the Company estimates its incremental borrowing rate based on the information available at lease commencement date for borrowings with a similar term.

**MOMENTUS INC.**

**NOTES TO THE CONDENSED CONSOLIDATED INTERIM FINANCIAL STATEMENTS**

**Note 2. Summary of Significant Accounting Policies** (cont.)

The Company's operating lease ROU assets are measured based on the corresponding operating lease liability adjusted for (i) payments made to the lessor at or before the commencement date, (ii) initial direct costs incurred, and (iii) tenant incentives under the lease. The Company does not assume renewals or early terminations unless it is reasonably certain to exercise these options at commencement. The Company elected the practical expedient which allows the Company to not allocate consideration between lease and non-lease components. Variable lease payments are recognized in the period in which the obligation for those payments is incurred. In addition, the Company elected the practical expedient such that it does not recognize ROU assets or lease liabilities for leases with a term of 12 months or less of all asset classes. Operating lease expense is recognized on a straight-line basis over the lease term. See Note 6 for additional details on the Company's leases.

***Income Taxes***

The Company accounts for income taxes in accordance with authoritative guidance, which requires the use of the asset and liability method. Under this method, deferred income tax assets and liabilities are determined based upon the difference between the financial statement carrying amounts and the tax basis of assets and liabilities and are measured using the enacted tax rate expected to apply to taxable income in the years in which the differences are expected to be reversed.

Significant judgment is required in determining any valuation allowance recorded against deferred tax assets. In assessing the need for a valuation allowance, management considers all available evidence, including past operating results, estimates of future taxable income, and the feasibility of tax planning strategies.

In the event that management changes its determination as to the amount of deferred tax assets that can be realized, the Company will adjust its valuation allowance with a corresponding impact to the provision for income taxes in the period in which such determination is made.

The Company is required to evaluate the tax positions taken in the course of preparing its tax returns to determine whether tax positions are "more-likely-than-not" of being sustained by the applicable tax authority. Tax benefits of positions not deemed to meet the "more likely than not" threshold would be recorded as a tax expense in the current year. The amount recognized is subject to estimate and management judgment with respect to the likely outcome of each uncertain tax position. The amount that is ultimately sustained for an individual uncertain tax position or for all uncertain tax positions in the aggregate could differ from the amount that is initially recognized.

***Concentrations of Risk***

Financial instruments that are exposed to concentrations of credit risk consist primarily of cash and cash equivalents. The Company places its cash and cash equivalents in banks that management believes are creditworthy, however deposits may exceed federally insured limits.

***Segment Reporting***

Operating segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision maker in deciding how to allocate resources and in assessing operating performance. In consideration of ASC Topic 280, *Segment Reporting* ("ASC Topic 280"), we are not organized around specific services or geographic regions.

Our chief operating decision maker ("CODM") uses financial information to evaluate our performance, which is the same basis on which our results and performance are communicated to our Board of Directors. All of the Company's long-lived assets are held domestically in the United States and of the $3.2 million of revenue recognized by the Company during the three months ended March 31, 2026, 1% was derived from customers domiciled in foreign countries. Based on the information described above and in accordance with the applicable literature, management has concluded that we are organized and operated as one operating and reportable segment.

***Recently Issued Accounting Standards***

Although there are several new accounting pronouncements issued or proposed by the FASB, which have been adopted or will be adopted as applicable, management does not believe any of these accounting pronouncements has had or will have a material impact on the Company's consolidated financial position or results of operations.

**Note 2. Summary of Significant Accounting Policies** (cont.)

In November 2024, the FASB issued ASU 2024-03, *Disaggregation of Income Statement Expenses (DISE)* ("ASU 2024-03"), that requires disclosures about specific types of expenses included in the expense captions presented on the face of the income statement as well as disclosures about selling expenses. Public entities must adopt the new guidance for fiscal years beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027. The amendments in ASU 2024-06 will be applied prospectively with the option for retrospective application and early adoption is permitted. The Company is in the process of evaluating the potential impact that ASU 2024-03 will have on its condensed consolidated interim financial statements and related disclosures.

In December 2025, the FASB issued ASU 2025-11, *Interim Reporting (Topic 270)—Narrow-Scope Improvements* ("ASU 2025-11"), which provides a clearer framework and more consistent application of interim disclosure requirements for public business entities. The guidance is effective for interim periods within annual periods beginning after December 15, 2027. The amendments in ASU 2025-11 will be applied prospectively with the option for retrospective application and early adoption is permitted. The Company does not anticipate that the adoption of ASU 2025-11 will have a material impact on its condensed consolidated interim financial statements and related disclosures.

**Note 8. Loan Payable**

***September 2025 Convertible Note***

On September 25, 2025, the Company entered into a Securities Purchase Agreement (the "September 2025 SPA") with an investor (the "September 2025 Private Placement") pursuant to which the Company agreed to sell (i) a Junior Secured Convertible Note having an aggregate principal amount of $1.6 million (the "September 2025 Convertible Note"), (ii) warrants to purchase up to 81,847 shares of Class A common stock (the "September 2025 Warrants"), and (iii) warrants to purchase up to $4.0 million of additional September 2025 Convertible Notes and September 2025 Warrants (the "AIR Warrants").

The September 2025 SPA provides that the Company will indemnify the investor for any claims and losses. This indemnification by the Company was an embedded derivative that required bifurcation and recognition as a derivative liability ("Indemnification Derivative"). The Indemnification Derivative instrument is recorded at fair value and marked-to-market each reporting period with changes in fair value being reflected in earnings. As of the issuance date, December 31, 2025, and March 31, 2026, the Indemnification Derivative was valued at zero.

The September 2025 Convertible Note bears an annual interest rate of 8%. Unless earlier converted, principal and any accrued unpaid interest on the September 2025 Convertible Note are due at maturity in September 2026. The September 2025 Convertible Note, including interest accrued thereon, is convertible at any time, in whole or in part, at the option of the holder into shares of Class A common stock at a conversion price of $19.92 per share, subject to certain beneficial ownership limitations provided for in the terms of the September 2025 Convertible Note. The September 2025 Convertible Note is a junior secured obligation of the Company and is secured by certain personal property of the Company.

The September 2025 Warrants have an exercise price of $24.99 per share. The September 2025 Warrants may be exercised at any time after issuance and will expire five years from the date of issuance. The exercise of the

**NOTES TO THE CONDENSED CONSOLIDATED INTERIM FINANCIAL STATEMENTS**

**Note 8. Loan Payable** (cont.)

September 2025 Warrants are subject to certain beneficial ownership limitations provided for in the terms of the September 2025 Warrants. The September 2025 Warrants meet the requirements for equity classification.

The Company received aggregate gross proceeds from the September 2025 Private Placement of approximately $1.5 million, before deducting estimated lender fees and debt issuance costs of $0.1 million paid by the Company.

The initial fair value of the AIR Warrants (discussed below) and the ELOC Pre-funded Warrants (see discussion in Note 9) exceed the net proceeds received from the September 2025 Private Placement. Therefore, upon allocating the net proceeds of the September 2025 Private Placement, no amounts were allocated to the September 2025 Warrants and the September 2025 Convertible Note was recorded at a 100% discount. The excess fair value of $1.4 million of the AIR Warrants and ELOC Pre-funded Warrants over the net proceeds received was recognized as a loss in other expense in the condensed consolidated statements of operations.

The September 2025 Convertible Note can be prepaid in full at any time, subject to a prepayment fee of 10%. The September 2025 Convertible Note will accelerate and become immediately due upon the occurrence of certain customary events of default including, but not limited to, failure to make payments when due, failure to observe or perform covenants or agreements contained in the September 2025 Convertible Note, the bankruptcy or insolvency of the Company or any of its subsidiaries and unsatisfied judgments against the Company. The mandatory redemption of the September 2025 Convertible Note upon one of these events of default was an embedded derivative that required bifurcation and recognition as a derivative liability ("September 2025 Default Redemption Derivative"). Furthermore, contingent interest related to these events of default was an embedded derivative also that required bifurcation and recognition as a derivative liability ("September 2025 Default Interest Derivative"). Both the September 2025 Default Redemption Derivative and the September 2025 Default Interest Derivative instruments are recorded at fair value and marked-to-market each reporting period with changes in fair value being reflected in earnings. As of the issuance date and each period end through March 31, 2026, both the September 2025 Default Redemption Derivative and the September 2025 Default Interest Derivative were valued at zero.

The September 2025 Convertible Note also contains certain negative covenants, including prohibitions on the incurrence of indebtedness, liens, amendments to the Company's organizational documents, dividends, redemption, related party transactions, and entry into any equity line of credit agreement or variable rate transactions other than an "at the market" offering of the Company's Class A common stock.

As of March 31, 2026, the September 2025 Convertible Note has a carrying amount of $0.6 million, consisting of principal of $1.4 million and net unamortized discount of $0.7 million. The September 2025 Convertible Note has future scheduled maturities of $1.4 million in 2026. For the three months ended March 31, 2026, interest recognized on the September 2025 Convertible Note totaled $0.5 million. This amount consists of cash interest expense of $0.03 million and non-cash amortization of debt discount of $0.5 million.

On April 17, 2026, all amounts outstanding under the September 2025 Convertible Note were converted into shares of Class A common stock (see Note 16).

***AIR Warrants***

In connection with the September 2025 Private Placement, the Company issued the AIR Warrants. The AIR Warrants were exercisable by the holder immediately with a five-year term and may be exercised in tranches based on the trading volume and price of the Company's Class A common stock. In addition, the Company may, at its discretion, deliver a call notice requiring the holder to exercise the AIR Warrants, in whole or in part (up to an amount not exceeding two times the average daily trading volume of the Company's Class A common stock over the relevant period), provided that certain trading conditions are satisfied (including the five-day average trading price equaling or exceeding 125% of the original conversion price of the underlying notes). If the trading conditions are not met at the time of the call notice, the holder is not obligated to exercise; however, the Company may cancel any unexercised portion of the AIR Warrants (effectively terminating the remaining commitment) if the holder does not proceed with the investment upon such call. This call feature provides the Company with the ability to compel realization or cancellation under various market conditions.

The AIR Warrants are classified as a liability under ASC Topic 480 as they embody a conditional obligation for the Company to transfer assets through the settlement of the underlying convertible notes.

**MOMENTUS INC.**

**NOTES TO THE CONDENSED CONSOLIDATED INTERIM FINANCIAL STATEMENTS**

**Note 8. Loan Payable** (cont.)

The AIR Warrants were initially measured at a fair value of $1.9 million on the issuance date, with a corresponding allocation from the proceeds of the September 2025 Private Placement, with the excess fair value of the AIR Warrants over the September 2025 Private Placement proceeds recognized in earnings. The AIR Warrants liability is recorded at fair value and marked-to-market each reporting period with changes in fair value being reflected in earnings. The Company determined the fair value of the AIR Warrants at issuance using two different approaches. Under the first approach, the instruments underlying the AIR Warrants are assumed to have value equal to proceeds received that would have been received upon exercise of the AIR Warrants and, under the second approach, the instruments underlying the AIR Warrants were valued using a convertible bond pricing model for the underlying convertible note and a BSM option pricing model for the underlying common warrants. The fair value was then determined based on the intrinsic value: the difference between the fair value of the instruments underlying the AIR Warrants and the proceeds that would be received upon exercise of the AIR Warrants. The following inputs were used in the convertible bond and BSM option pricing models:

---

| | | |
|:---|:---|:---|
| | **Underlying Investor Warrants (BSM)** | **Junior Convertible Notes** |
| Expected term (years) | 5.00 | 0.92 |
| Stock price | $22.13 | $22.13 |
| Volatility | 87.50% | 45.00% |
| Risk-free rate | 3.75% | 3.49% |
| Dividend yield | —% | —% |
| Discount rate on the note | N/A | 78.64% |
| Exercise price of AIR Warrants (millions) | $3.7 | $3.7 |

---

No AIR Warrants were exercised during the three months ended March 31, 2026. On April 17, 2026, the Company terminated the AIR Warrants as provided therein following the full conversion of the September 2025 Convertible Note into shares of Class A common stock (see Note 16).

***May 2025 Loan***

On May 30, 2025, the Company and J.J. Astor & Co. entered into a loan agreement (the "May 2025 Loan") pursuant to which the Company may borrow up to $1.5 million in two tranches of $0.75 million each (the first tranche referred to as the "Initial Tranche" and the second as the "Second Tranche") and paid debt issuance costs of $0.2 million. The May 2025 Loan has a maturity date of March 6, 2026, and is payable in 40 weekly installments of $25 thousand, with at least 10% in cash and the remainder in shares at a conversion price of $30.35 per share. The May 2025 Loan can be prepaid in full at any time, subject to a prepayment fee of 120% of the outstanding principal plus costs.

Amounts borrowed under the May 2025 Loan are secured by a lien on substantially all of the assets of the Company. Upon event of default, amounts owing under the May 2025 Loan increase by 120% and are convertible into shares of Class A common stock at a conversion price equal to 80% of the average of the four lowest volume weighted average closing prices of the Class A common stock during the 20 trading days immediately prior to conversion. The Company elected the FVO for recognition of the May 2025 Loan as permitted under ASC Topic 825.

In addition, in connection with the May 2025 Loan, the Company agreed to issue J.J. Astor & Co. warrants to purchase up to 53,386 shares of Class A common stock with an exercise price of $30.35 per share, subject to adjustment (the "Initial Tranche Warrants"), comprising 26,688 warrants for each tranche. The Initial Tranche Warrants had a fair value of $0.6 million. The warrants are fully vested and expire five years from the date of issuance. The Company determined the fair value of the Initial Tranche Warrants by using a BSM option pricing model, with the following assumptions:

On June 17, 2025, the Company and J.J. Astor & Co. entered into an amendment to the May 2025 Loan (the "June 2025 Loan Amendment"). The June 2025 Loan Amendment, among other things, revised the conditions for funding the Second Tranche to occur within three business days after the effectiveness of a resale registration statement, subject to Nasdaq listing maintenance, a stock price of not less than $22.31, a market capitalization of not less than $6.7 million, and trading volume conditions. It also reduced the conversion price on both tranches to the lesser of the closing price of the Company's Class A common stock June 2025 Loan Amendment date and the closing price prior to the Second Tranche issuance. Additionally, the June 2025 Loan Amendment introduced a cash make-whole payment upon conversion equal to the difference between the conversion price and the lower of the closing price on conversion or the lowest volume weighted average closing price over 20 prior trading days. If not paid in cash, the Company will issue shares equal to the make-whole amount divided by the make-whole price. If the Company completes an equity offering sufficient to repay the Initial Tranche before the Second Tranche funding date, the obligation to issue the Second Tranche is suspended, with a $0.1 million termination fee and issuance of warrants for 26,688 shares of Class A common stock (the "Second Tranche Warrants").

The May 2025 Loan contains customary events of default, upon which the outstanding obligations may be accelerated. The loan ranks senior to unsecured indebtedness. The Company was in compliance with all covenants prior to extinguishment of the May 2025 Loan on July 1, 2025.

On July 1, 2025, the Company prepaid $1.0 million, inclusive of the $0.1 million termination fee, in order to extinguish the May 2025 Loan. In addition, in relation to the extinguishment of the May 2025 Loan on July 1, 2025, the 26,688 Second Tranche Warrants were issued with an exercise price of $20.17 per share. The Second Tranche Warrants had a fair value of $0.4 million, which was included in the measurement of loss on extinguishment of the May 2025 Loan. The Second Tranche Warrants were exercisable immediately after issuance and will expire five years from the date of issuance. The Company determined the fair value of the Second Tranche Warrants by using a BSM option pricing model, with the following assumptions:

|:---|:---|
| Expected term (years) | 5.00 |
| Stock price | $20.17 |
| Volatility | 90.00% |
| Risk-free rate | 3.84% |
| Dividend yield | 0.00% |

The Company recognized a $0.5 million loss on extinguishment in July 2025 related to the May 2025 Loan.

***AGP Convertible Promissory Note***

On May 13, 2025, the Company entered into an unsecured convertible promissory note (the "May 2025 Convertible Note") with A.G.P./Alliance Global Partners ("AGP") for a principal amount of $1.2 million, issued in exchange for AGP's services in facilitating the issuance of equity securities under the MSA with VLD (see Note 9). The May 2025 Convertible Note bears interest at 4.5% per annum and matures on November 13, 2026, unless earlier converted or prepaid. AGP may elect to convert all or any portion of the outstanding principal and accrued interest into shares of the Company's Class A common stock at a conversion price of $29.81 per share, based on the closing price on May 9, 2025, subject to adjustment for stock splits, dividends, or similar events. At maturity, all outstanding principal and accrued interest are payable in cash or, at AGP's option, in shares of Class A common stock at the conversion price. The Company may prepay the May 2025 Convertible Note in whole or in part at any time without penalty.

The May 2025 Convertible Note is classified as a liability under ASC Topic 718, as it was issued to a non-employee for services, and is remeasured at fair value at each reporting period until settlement, with changes in fair value recognized in earnings as part of operating expenses. The note represents payment for legal services incurred in

**Note 8. Loan Payable** (cont.)

relation to the VLD MSA. Upon issuance, the Company recognized $0.3 million of legal expense related to the May 2025 Convertible Note in selling, general and administrative expenses in the Company's condensed consolidated statements of operations.

The May 2025 Convertible Note contains customary events of default, upon which the outstanding obligations may be accelerated. The note is unsecured and ranks pari passu with the Company's other unsecured indebtedness. The Company was in compliance with all covenants prior to settlement on January 9, 2026.

On June 17, 2025, the Company and AGP executed a letter agreement (the "June 2025 Note Amendment") modifying the terms of the May 2025 Convertible Note. The June 2025 Note Amendment provided that a new convertible promissory note with a reduced principal amount of $0.5 million (the "Amended Note") will replace the May 2025 Convertible Note. AGP agreed to waive any claim or recourse with respect to the $0.7 million differential between the May 2025 Convertible Note and the Amended Note. The Amended Note would retain substantially similar terms to the May 2025 Convertible Note, including the interest rate, maturity, conversion price, and conversion mechanics, with the only change being the reduction of the principal from $1.2 million to $0.5 million. The June 2025 Note Amendment was accounted for as a modification, with no change to the accounting treatment, as the note remains liability-classified and continues to be remeasured at fair value at each reporting period. No additional costs or premiums were recognized.

On January 9, 2026, the Company exchanged the May 2025 Convertible Note for a new unsecured convertible promissory note (the "January 2026 Convertible Note") with substantially similar terms, except that the conversion price on the January 2026 Convertible Note was reduced from $29.8095 to $10.00 per share of Class A common stock. On the same date, the January 2026 Convertible Note was settled through the issuance of 50,000 shares of Class A common stock. The Company recognized legal expense of $0.3 million during the three months ended March 31, 2026, representing the change in the fair value of the liability-classified award immediately prior to settlement.

***SIV Convertible Promissory Notes***

On July 12, 2024, the Company and Space Infrastructure Ventures ("SIV") entered into a secured convertible promissory note (the "July 2024 Convertible Note") pursuant to which the Company borrowed $2.3 million as of September 26, 2024. The July 2024 Convertible Note bore an annual interest rate of 15%. Principal on the July 2024 Convertible Note was originally to be re-paid in four equal payments on a quarterly basis, commencing on December 1, 2024, and maturing on September 1, 2025, at which time all accrued interest is due. The July 2024 Convertible Note was subsequently amended in November 2024 which, among other things, provided that amounts owed under the July 2024 Convertible Note may be converted into Class A common stock at any time.

Amounts borrowed under the July 2024 Convertible Note were secured by a lien on substantially all of the assets of the Company. In lieu of cash payments of accrued interest, SIV, in its sole discretion, could elect to receive shares of Class A common stock at an original conversion price of $132.27 per share. On the maturity date, subject to the satisfaction of applicable legal and regulatory conditions, all outstanding obligations under the July 2024 Convertible Note would automatically convert into Class A common stock at the conversion price.

The July 2024 Convertible Note could be prepaid in full at any time, subject to a prepayment penalty fee of 10%. The July 2024 Convertible Note would accelerate and become immediately due upon the occurrence of certain customary events of default, including failure to pay amounts owing when due and/or certain events involving a discontinuation of our business or certain types of proceedings involving insolvency, bankruptcy, receivership and the like, or a change of control of Momentus. Contingent interest related to these events of default was an embedded derivative that required bifurcation and recognition as a derivative liability ("July 2024 Default Interest Derivative"). The July 2024 Default Interest Derivative instrument was recorded at fair value and marked-to-market each reporting period with changes in fair value being reflected in earnings. As of the issuance date, each subsequent period end, and upon extinguishment at final maturity of the July 2024 Convertible Note on December 1, 2025, the July 2024 Default Interest Derivative was valued at zero.

On October 24, 2024, the Company and SIV entered into a secured convertible promissory note (the "October 2024 Convertible Note" and, collectively with the July 2024 Convertible Note, the "SIV Convertible Notes") pursuant to which the Company borrowed $3.0 million in two tranches, consisting of (i) an initial loan in the principal amount of $2.0 million, and (ii) an additional $1.0 million in principal amount which could originally be borrowed from December 2, 2024 through February 14, 2025. Borrowings under the October 2024 Convertible Note bear interest at

**Note 8. Loan Payable** (cont.)

15% per annum. The October 2024 Convertible Note had an original maturity date of October 24, 2025, at which time all principal and accrued interest is due. The October 2024 Convertible Note was subsequently amended in November 2024 which, among other things, (i) accelerated the borrowing of the additional $1.0 million in principal in November 2024 and (ii) provided that amounts owed under the October 2024 Convertible Note may be converted into Class A common stock at any time.

Amounts borrowed under the October 2024 Convertible Note are secured by a lien on substantially all of the assets of the Company. At any time after the date that is six months after the original issuance date of the October 2024 Convertible Note, SIV, in its sole discretion, may convert some or all of the outstanding obligations under the October 2024 Convertible Note into shares of Class A common stock at an original conversion price of $132.27 per share.

The October 2024 Convertible Note can be prepaid in full at any time, subject to a prepayment fee of 10%. The October 2024 Convertible Note will accelerate and become immediately due upon the occurrence of certain customary events of default, including failure to pay amounts owing when due and/or certain events involving a discontinuation of our business or certain types of proceedings involving insolvency, bankruptcy, receivership and the like, or a change of control of the Company. Contingent interest related to these events of default was an embedded derivative that required bifurcation and recognition as a derivative liability ("October 2024 Default Interest Derivative"). The October 2024 Default Interest Derivative instrument is recorded at fair value and marked-to-market each reporting period with changes in fair value being reflected in earnings. As of the issuance date and each subsequent period end through March 31, 2026, the October 2024 Default Interest Derivative was valued at zero.

The SIV Convertible Notes require SIV's consent for the Company to take certain actions, such as increasing compensation, purchasing assets outside the ordinary course of business, extending financing, making capital expenditures in excess of $0.1 million, repaying debts outside the ordinary course of business, or investing in any entity or enterprise.

The debt premium on the first tranche of the October 2024 Convertible Note, as amended, was being amortized over the term of the October 2024 Convertible Note, prior to the September 2025 Amendment, using an effective interest rate of (18)%. The debt issuance costs on the second tranche of the October 2024 Convertible Note, as amended, were being amortized over the term of the October 2024 Convertible Note, until the September 2025 Amendment discussed below, using an effective interest rate of 348%.

On March 3, 2025, the Board of Directors of the Company approved a reduction in the conversion price for the July 2024 Convertible Note from $132.27 per share to $37.84 per share during the period beginning on March 3, 2025, and continuing until there are no further obligations outstanding under the July 2024 Convertible Note. The reduction in the conversion price for the July 2024 Convertible Note was accounted for as an extinguishment. The Company recognized a $0.1 million gain on extinguishment in the condensed consolidated statements of operations related to this extinguishment, resulting from the difference between the carrying value and reacquisition price of the July 2024 Convertible Note. The Company recognized a debt premium of $0.2 million related to the July 2024 Convertible Note, which was amortized over the term of the July 2024 Convertible Note, prior to the September 2025 Amendment, using an effective interest rate of (25)%.

On May 16, 2025, the Company offered SIV the opportunity to convert amounts outstanding under the July 2024 Convertible Note, at a reduced conversion price of $31.59 per share, into up to 6,307 shares of Class A common stock and, thereafter, to convert amount outstanding under the October 2024 Convertible Note, at a reduced conversion price of $31.59 per share. Pursuant to this offer, and as part of the Company's May 2025 contractual repayment, on May 20, 2025, SIV converted $0.2 million of principal of the July 2024 Convertible Note into 6,307 shares of Class A common stock at a conversion price of $31.59 per share. The conversion was accounted for as a partial extinguishment of the July 2024 Convertible Note, resulting in a $0.01 million gain on extinguishment in the condensed consolidated statements of operations. In addition to the $0.2 million of principal converted into equity, the Company repaid $0.3 million of principal in cash, and postponed $0.1 million of payments, including $0.06 million of principal and $0.04 million of interest, to the following quarter. The postponement was accounted for as a modification of the July 2024 Convertible Note. SIV did not convert any amounts outstanding under the October 2024 Convertible Note pursuant to this offer.

On September 8, 2025, the Company amended the SIV Convertible Notes (the "September 2025 Amendment"). The September 2025 Amendment, among other things, extended the maturity date of the July 2024 Convertible Note and the October 2024 Convertible Note to December 1, 2025, and March 1, 2026, respectively. As a result of the

**Note 8. Loan Payable** (cont.)

September 2025 Amendment, the $2.7 million outstanding principal amount of the October 2024 Convertible Note is payable in two tranches, with the first tranche of $1.0 million due on December 1, 2025, and the remaining $1.7 million, plus unpaid accrued interest, due at maturity on March 1, 2026. The September 2025 Amendment further changed the conversion price of both of the SIV Convertible Notes to an amount equal to the lower of (i) $19.81 per share and (ii) a 10% discount to the closing price of the Class A common stock on the day prior to each conversion, but in no event lower than $3.57 per share. The September 2025 Amendment was accounted for as an extinguishment of both of the SIV Convertible Notes. The Company recognized a $2.4 million loss on extinguishment in the condensed consolidated statements of operations related to the September 2025 Amendment, resulting from the difference between the carrying value and reacquisition price of the SIV Convertible Notes.

In addition, in connection with the September 2025 Amendment, the Company issued to SIV warrants to purchase up to 112,045 shares of Class A common stock with an exercise price of $19.81 per share (the "September 2025 SIV Warrants"). The September 2025 SIV Warrants had a fair value of $1.7 million which was included in measurement of the September 2025 Amendment loss on extinguishment. The September 2025 SIV Warrants were exercisable immediately after issuance and will expire five years from the date of issuance. The Company determined the fair value of the September 2025 SIV Warrants by using a BSM option pricing model, with the following assumptions:

---

| | |
|:---|:---|
| Expected term (years) | 5.00 |
| Stock price | $21.42 |
| Volatility | 87.50% |
| Risk-free rate | 3.57% |
| Dividend yield | 0.00% |

---

Furthermore, in connection with the September 2025 Amendment, the Company also agreed to amend each of the October 2024 SIV Warrants and December 2024 SIV Warrants to purchase up to an aggregate of 25,951 shares of Class A common stock at an exercise price of $132.27 per share and a termination date of April 24, 2030 (the "SIV Modified Warrants"). The SIV Modified Warrants were amended on September 8, 2025, to have a reduced exercise price of $19.81 per share. The Company estimated the fair value of the SIV Modified Warrants immediately before and after modification using the BSM option pricing model and determined an incremental increase in fair value of approximately $0.2 million. The incremental change in fair value of the SIV Modified Warrants was included in measurement of the September 2025 Amendment loss on extinguishment. The Company determined the incremental fair value of the SIV Modified Warrants by using a BSM option pricing model, with the following assumptions:

---

| | | |
|:---|:---|:---|
| | **Pre-modification** | **Post-modification** |
| Expected term (years) | 4.63 | 4.63 |
| Stock price | $21.42 | $21.42 |

| Risk-free rate | 3.55% | 3.55% |
| Dividend yield | 0.00% | 0.00% |

The Company capitalized cash debt issuance costs of $0.03 and recognized a debt premium of $0.3 million on the October 2024 Convertible Note in relation to the September 2025 Amendment. The net debt premium of $0.3 million was being amortized over the term of the October 2024 Convertible Note, until the December 2025 Amendment discussed below, using effective interest rates of (7)% and (34)% for the first and second tranches of the October 2024 Convertible Note, respectively. The Company also recognized a $0.1 million debt discount on the July 2024 Convertible Note in relation to the September 2025 Amendment. The debt discount was being amortized over the term of the July 2024 Convertible Note, until extinguishment in December 2025, using an effective interest rate of 103%.

The September 2025 Amendment permits the Company to incur up to $4.0 million of indebtedness on or after December 1, 2025, that is pari passu with the unpaid balance of the SIV Convertible Notes, provided that the Company issues to SIV warrants to purchase up to 10% of the total number of shares of Class A common stock SIV has converted under both of the SIV Convertible Notes after September 8, 2025, with the exercise price per share to correspond with the conversion price applicable under the SIV Convertible Notes at the time of the debt incurrence.

Thereafter, the Company will continue to issue to SIV warrants to purchase shares of Class A common equal to 10% of the shares converted from time to time under the SIV Convertible Notes, with the warrants having an exercise price equal to the corresponding conversion price at the time of issuance.

The Company paid $0.1 million to pay off the July 2024 Convertible Note in December 2025.

On December 5, 2025, the Company amended the October 2024 Convertible Note (the "December 2025 Amendment"). The December 2025 Amendment, among other things, deferred the first payment tranche of $1.0 million principal, originally due December 1, 2025, to May 1, 2026, and all remaining accrued unpaid interest, originally due March 1, 2026, to May 1, 2026. It also delayed the date on or after which the Company may incur up to $4.0 million of additional indebtedness pari passu with the October 2024 Convertible Note from December 1, 2025, to March 1, 2026.

In addition, in connection with the December 2025 Amendment, the Company issued to SIV warrants to purchase up to 13,446 shares of Class A common stock with an exercise price of $14.10 per share (the "December 2025 SIV Warrants"). The December 2025 SIV Warrants had a fair value of $0.1 million which was accounted for as a debt modification cost for the October 2024 Convertible Note. The December 2025 SIV Warrants are exercisable immediately after issuance and expire five years from the date of issuance. The Company determined the fair value of the December 2025 SIV Warrants by using a BSM option pricing model, with the following assumptions:

---

|:---|:---|
| Expected term (years) | 5.00 |
| Stock price | $14.28 |
| Volatility | 82.50% |
| Risk-free rate | 3.72% |

The Company recognized $0.1 million of debt issuance costs related to the December 2025 SIV Warrants in addition to an unamortized debt premium of $0.1 million on the first tranche of the October 2024 Convertible Note. The net debt discount of $0.04 million is being amortized over the term of the October 2024 Convertible Note using effective interest rates of 13% and 27% for the first and second tranches of the October 2024 Convertible Note, respectively.

During the three months ended March 31, 2026, the Company converted $0.8 million of principal and $0.2 million of accrued interest on the October 2024 Convertible Note into 159,030 shares of Class A common stock. The conversions were accounted for under ASC Sub-Topic 470-20, with no gain or loss recognized.

During the three months ended March 31, 2025, the Company converted $0.6 million of principal and $0.1 million of accrued interest on the SIV Convertible Notes into 10,645 shares of Class A common stock. The conversions were accounted for under ASC Sub-Topic 470-20, with no gain or loss recognized.

As of March 31, 2026, the October 2024 Convertible Note has a carrying value of $1.1 million, consisting of principal of $1.1 million, net unamortized discount of $0.01 million, and accrued interest of $0.2 million. The October 2024 Convertible Note has future scheduled maturities of $1.1 million in 2026. For the three months ended March 31, 2026, interest recognized on the October Convertible Note totaled $0.1 million. This amount consists of cash interest expense of $0.1 million and non-cash amortization of net debt discounts of $0.02 million. For the three months ended March 31, 2025, interest recognized on the SIV Convertible Notes totaled $(0.1) million. This amount consists of non-cash amortization of net debt premiums of $(0.3) million, partially offset by cash interest expense of $0.2 million.

On April 17, 2026, all amounts outstanding under the October 2024 Convertible Note were converted into shares of Class A common stock (see Note 16).

**Note 9. Stockholders' Equity**

***Common Stock and Preferred Stock***

Effective December 17, 2025, the Company's stockholders approved a 1-for-17.85 reverse stock split of the Company's Class A common stock. As a result of the reverse stock split, every 17.85 shares of Class A common

**Note 9. Stockholders' Equity** (cont.)

stock issued and outstanding on December 17, 2025, were automatically combined into one share of Class A common stock. Any fractional shares resulting from the reverse stock split were rounded up to the next nearest whole share of Class A common stock.

To effectuate the December 2025 1-for-17.85 reverse stock split, the Company filed a Certificate of Amendment to the Second Amended and Restated Certificate of Incorporation, as amended. As a result of the reverse stock split, there was no change to par value and the total number of authorized shares of Class A common stock.

Pursuant to the terms of the Second Amended and Restated Certificate of Incorporation, as amended, the Company is authorized and has available a total of 270,000,000 shares of stock, consisting of (i) 250,000,000 shares of Class A common stock, par value $0.00001 per share, (ii) zero shares of Class B common stock, par value $0.00001 per share, and (iii) 20,000,000 shares of Series A preferred stock, par value $0.00001 per share.

Each share of Series A preferred stock is non-voting and convertible, at the option of the holder thereof, at any time and from time to time, and without the payment of additional consideration by the holder thereof, into 0.56 shares of Class A common stock. The Series A preferred stock is senior to the Company's common stock with respect to dividends and liquidation distributions. In the event of a liquidation, dissolution, or winding up of the Company, holders of Series A preferred stock are entitled to receive, before any payment to common stockholders, the greater of the $20.80 per share of Series A preferred stock or the as-converted value based on conversion into shares of Class A common stock. Holders are entitled to dividends on an as-converted basis, proportionate to any dividends declared on common stock, which are discretionary and non-cumulative. The Series A preferred stock is classified as permanent equity under ASC Topic 480, as it is not mandatorily redeemable and lacks redemption triggers outside of a final liquidation event.

Also on the effective date of the reverse stock split, all options, warrants and other convertible securities of the Company outstanding immediately prior to the reverse stock split were adjusted by dividing the number of shares of Class A common stock into which the options, warrants and other convertible securities were exercisable or convertible by 17.85 and multiplying the exercise or conversion price thereof by 17.85, all in accordance with the terms of the plans, agreements or arrangements governing such options, warrants and other convertible securities and subject to rounding to the nearest whole share. Such proportional adjustments were also made to the number of shares and RSUs issued and issuable under the Company's equity compensation plan.

The Company has retroactively adjusted all periods presented for the effects of the December 2025 1-for-17.85 reverse stock split.

***At-The-Market Offering***

On September 19, 2025, the Company entered into an At-the-Market Equity Offering Sales Agreement with AGP (the "ATM Sales Agreement"). Pursuant to the ATM Sales Agreement, the Company may sell, from time to time, at its option, up to $7.4 million in aggregate principal amount of an indeterminate amount of shares of the Class A common stock through AGP acting as sales agent. If the Company's public float increases such that it may sell additional amounts under the ATM Sales Agreement and the Registration Statement (as defined below), the Company may file supplements to the prospectus included in the Registration Statement prior to making additional sales.

Any shares of Class A common stock to be offered and sold under the ATM Sales Agreement will be issued and sold (i) by methods deemed to be an "at-the-market offering" as defined in Rule 415(a)(4) promulgated under the Securities Act, or in negotiated transactions, if authorized by the Company, and (ii) pursuant to, and only upon the effectiveness of, a Registration Statement on Form S-3 filed by the Company with the SEC on September 22, 2025 for an offering of up to $50.0 million of various securities, including shares of the Company's Class A common stock, preferred stock, debt securities, warrants and/or units for sale to the public in one or more public offerings (the "Registration Statement"). Under the ATM Sales Agreement, AGP will be entitled to compensation at a commission rate of up to 3.0% of the gross sales price per share sold.

During 2025, the Company filed several prospectus supplements to the Registration Statement increasing the aggregate principal amount. As of December 31, 2025, the aggregate principal amount was $17.4 million. On February 6, 2026, the Company filed a prospectus supplement to the Registration Statement increasing the aggregate principal amount to $21.6 million and, on February 9, 2026, the Company filed another prospectus supplement to

the Registration Statement further increasing the aggregate principal amount to $50.0 million.

***Shares issued in settlement of accounts payable***

During the three months ended March 31, 2026, the Company settled $0.1 million of accounts payable with a vendor through the issuance of 5,723 of Class A common stock. The fair value of the shares issued was determined to be $0.1 million based on the closing price of the Class A common stock on the settlement dates and no gain or loss on extinguishment was recognized as fair value was equal to the carrying amount of the liability settled.

***January 2026 Securities Purchase Agreement***

On January 5, 2026, the Company entered into a Securities Purchase Agreement with an investor, pursuant to which the Company issued and sold to an investor in a private placement transaction (the "January 2026 Offering"), (i) pre-funded warrants (the "January 2026 Pre-Funded Warrants") to purchase 925,926 shares of the Company's Class A common stock and (ii) warrants to purchase 925,926 shares of Class A common stock (the "January 2026 Warrants").

The January 2026 Pre-Funded Warrants have an exercise price of $0.00001 per share and are exercisable any time after issuance, and will not expire until exercised. The January 2026 Warrants have an exercise price per share of Class A common stock equal to $5.40 per share and expire February 6, 2031. The January 2026 Offering closed on January 6, 2026.

In connection with the January 2026 Offering, the Company entered into a Placement Agency Agreement with the agency which assisted with the transaction. The Company paid a cash placement agent commission equal to 7.0% of gross proceeds from the January 2026 Offering and issued warrants (the "January 2026 Placement Agent Warrants") to purchase 46,296 shares of Class A common stock at an exercise price of $5.94, exercisable beginning 180 days after the commencement of sales in the offering and expiring January 6, 2031. The $0.3 million fair value of the January 2026 Placement Agent Warrants was accounted for as an additional equity issuance cost for the January 2026 Offering, which was recorded to additional paid-in-capital.

The Company estimated the fair value of the January 2026 Pre-Funded Warrants based on the fair value of the Company's Class A common stock from the issuance date, less the $0.00001 exercise price. The Company estimated the fair value of the January 2026 Warrants and the January 2026 Placement Agent using the BSM option

and will not expire until exercised. The Company evaluated the issuance of the B&M Pre-funded Warrants under ASC Topic 718 and determined that they are equity classified and should be measured at their grant-date fair value, with the related expense recognized immediately upon issuance, as the underlying services were fully rendered prior to grant. The fair value of the shares and B&M Pre-funded Warrants issued was determined to be $1.2 million, based on the closing price of the Class A common stock on the settlement date, resulting in $0.1 million of additional expense recognized for the difference between the fair value shares and pre-funded warrants and the carrying amount of the liability settled.

During the three months ended March 31, 2026, the Company issued 19,210 shares of Class A common stock as a result of all of the B&M Pre-funded Warrants being exercised.

***September 2025 Equity Line of Credit***

As part of the September 2025 Private Placement, on September 25, 2025, the Company entered into an equity purchase agreement (the "ELOC") with an investor and a registration rights agreement, pursuant to which the Company has the right, but not the obligation, to direct the investor to purchase up to $50.0 million in shares of Class A common stock, subject to certain limitations and conditions set forth in the ELOC, including the requirement that the trading price of the Class A common stock as listed on Nasdaq is at or above 106% of the purchase price, with a purchase price of $22.13 per share to be paid by the investor. The Company will control the timing and amount of any sale of shares pursuant to the ELOC.

The term of the ELOC began on September 25, 2025, and will end on the earlier of (i) the date on which the investor shall have purchased shares of Class A common stock equal to $50.0 million, (ii) 36 months from September 30, 2025, the date the Registration Statement on Form S-3 was declared effective, (iii) written notice of termination by the Company to the investor (which shall not occur at any time that the investor holds any of the shares of Class A common stock purchased under the ELOC, or within 30 days of the sale to the investor of shares of Class A common stock pursuant to the ELOC), or (iv) written notice of termination by the investor to the Company. The ELOC represents a forward contract for the sale of Class A common stock and the Company will record sales of the Class A common stock under the ELOC as they occur.

In consideration for the investor's execution and delivery of, and performance under, the ELOC, the Company issued prefunded warrants to purchase 37,816 shares of Class A common stock (the "ELOC Pre-funded Warrants"). The ELOC Pre-funded Warrants have an exercise price of $0.00001 per share and are exercisable any time after issuance, and will not expire until exercised. Unless the ELOC is terminated by January 26, 2026, the number of exercisable prefunded warrants will increase to 42,017 shares. The ELOC Pre-funded Warrants are liability classified. The ELOC Pre-funded Warrants were initially measured at a fair value of $0.8 million on the issuance date, based on the closing price of the Class A common stock on the issuance date, with a corresponding allocation from the proceeds of the September 2025 Private Placement (see Note 8).

The ELOC Pre-funded Warrants liability was recorded at fair value and marked-to-market each reporting period with changes in fair value being reflected in earnings. On November 21, 2025, the Company issued 37,816 shares of Class A common stock as a result of all of the ELOC Pre-funded Warrants being exercised.

On December 23, 2025, the Company entered into a First Amendment to the ELOC (the "ELOC Amendment") with the investor. The ELOC Amendment modified the purchase price mechanism for shares issuable upon delivery of a put notice from a fixed price of $1.24 per share to a variable price equal to 94% of the lowest trading price of the Class A common stock reported during the three consecutive trading days commencing on the date the applicable put notice is delivered. As of March 31, 2026, no shares have been sold under the ELOC.

The number of shares under the ELOC Pre-funded Warrants increased by 4,202 as the ELOC was not terminated on January 26, 2026. The Company issued 4,202 shares of Class A common stock as a result of these additional ELOC Pre-funded Warrants being exercised in January 2026.

***August 2025 Warrant Inducement***

On April 12, 2025, the Company entered into a Master Services Agreement (the "MSA") with Velo3D, Inc. ("VLD"), a provider of additive manufacturing solutions, also referred to as 3D printing, pursuant to which VLD will provide services to design and produce components and systems that will be utilized by the Company or its customers in its spacecraft, systems, and components. The MSA has a term of five years and provides the Company with priority access to manufacturing capacity equivalent to approximately $3,000,000 annually, corresponding to the output of two Sapphire XC 3D metal printers or comparable equipment. If the Company does not fully utilize this capacity in a given year, it may receive credits equal to 20% of the unused value (net of service fees paid) in the first year and 50% thereafter. The Company has an option to purchase the equipment after the second anniversary of the MSA at 70% of its amortized value.

In exchange for the services, the Company issued an aggregate of 26,749 shares of Class A common stock and 673,408 shares of Series A preferred stock. The grant-date fair value of the equity issued was determined to be $10.7 million, based upon the enterprise value of the company on the date of the transaction and considering the quoted market price of the Class A common stock on the issuance date for the common shares issued and, for the Series A preferred stock, an as-converted basis using the same closing price adjusted for its conversion ratio and features. A Discount for Lack of Marketability ("DLOM") was applied to the aggregate valuation. This discount was determined based on certain assumptions, including a volatility rate of 45.0% per year and a length of holding period restriction of 0.5 years. The Company evaluated the issuance of these shares under ASC Topic 718 and determined

**Note 9. Stockholders' Equity** (cont.)

that shares were equity classified and, at contract inception, there was no recognition required related to the MSA as no goods or services had been delivered.

The credit provision related to unused capacity was determined to be an embedded derivative under ASC Topic 815 (the "Credit Provision Derivative"). The Credit Provision Derivative was bifurcated from the contract and is recorded at fair value and marked-to-market each reporting period with changes in fair value being reflected in earnings. As of the inception date, the Credit Provision Derivative was valued at zero.

On August 14, 2025, the Company irrevocably waived its right under the MSA to cancel shares of the Company's capital stock held by VLD upon expiration or termination of the MSA (the "VLD Amendment"). The shares of Series A preferred stock held by VLD are fully vested and non-forfeitable. This amendment was accounted for as a Type I Modification under ASC Topic 718 and the Company recognized the grant-date fair value of $10.7 million immediately as a prepaid asset. Of the $10.7 million recognized on August 14, 2025, $2.1 million was recorded within prepaids and other current assets and $8.6 million was recorded within other non-current assets in our condensed consolidated balance sheets. As only term that changed as a result of the VLD Amendment was related to vesting, there was no change in fair value of the equity issued as a result of the amendment and no incremental fair value recognized. The prepaid asset will be amortized to expense over the 5 year period of the MSA as services are provided to the Company.

On October 17, 2025, VLD converted 126,000 shares of the Company's Series A preferred stock into 70,588 shares of Class A common stock.

During the year ended December 31, 2025, the Company only received $0.1 million out of the $3.0 million annual prepayment of services from VLD. The Company determined that $1.7 million of the prepaid services would not be utilized in the first annual period of the MSA and were thus not recoverable as of December 31, 2025. In relation to this underutilization of prepaid services, $0.2 million of other income was recognized for an increase in the fair value of the Credit Provision Derivative. The Credit Provision Derivative asset is recorded in prepaids and other current assets in the condensed consolidated balance sheets.

On February 9, 2026, VLD converted 547,408 shares of the Company's Series A preferred stock into 306,672 shares of Class A common stock. As a result of the conversion, there are no shares of the Company's Series A preferred stock outstanding.

***March 2025 Warrant Inducement***

On March 20, 2025, the Company entered into a warrant inducement agreement (the "March 2025 Warrant Inducement") with an investor who was holding the Investor Modified Warrants (see discussion of the February 2025 Offering below). Pursuant to the March 2025 Warrant Inducement, on March 21, 2025, the investor agreed to exercise for cash 60,025 of the Investor Modified Warrants at an exercise price of $34.45 per share. The investor paid gross proceeds of $2.1 million, before deducting offering fees and other expenses of $0.2 million payable by the Company. Prior to entering into the March 2025 Warrant Inducement, the Investor Modified Warrants were immediately exercisable at an exercise price of $67.83 per share. Net proceeds of $1.9 million from the exercise of the Investor Modified Warrants was recorded to additional paid-in capital.

The Company agreed to issue new warrants to purchase up to 120,049 shares of Class A common stock, with an exercise price of $35.70 per share (the "March 2025 Warrants"), in consideration of the investor's agreement to exercise the Investor Modified Warrants. The March 2025 Warrants were exercisable immediately after issuance and expire five years from the date of issuance. The March 2025 Warrants meet the requirements for equity classification.

The Company may not effect the exercise of certain March 2025 Warrants, and the investor will not be entitled to exercise any portion of any such March 2025 Warrants, which, upon giving effect to such exercise, would cause the aggregate number of shares of Class A common stock beneficially owned by the investor of such March 2025 Warrants (together with its affiliates) to exceed 4.99% of the number of shares of Class A common stock outstanding immediately after giving effect to the exercise, as such percentage ownership is determined in accordance with the terms of such March 2025 Warrants.

**Note 9. Stockholders' Equity** (cont.)

On March 24, 2025, only 18,544 shares of Class A common stock were delivered to the investor due to beneficial ownership limitations upon the exercise of the Investor Modified Warrants. The remaining 41,481 shares were subsequently delivered to the investor during the year ended December 31, 2025.

***February 2025 Public Offering***

On February 11, 2025, the Company consummated a "best efforts" public offering (the "February 2025 Offering") of an aggregate of (i) 16,807 shares of Class A common stock at a purchase price of $70.06 per share, (ii) pre-funded warrants (the "February 2025 Pre-funded Warrants") to purchase 54,560 shares of Class A common stock, and (iii) warrants to purchase 71,367 shares of Class A common stock (the "February 2025 Warrants").

The purchase price of each February 2025 Pre-funded Warrant was equal to the price per share of Class A common stock being sold in the February 2025 Offering minus $0.00001. The February 2025 Pre-funded Warrants have an exercise price of $0.00001 per share and are exercisable any time after the issuance, and will not expire until exercised. The February 2025 Warrants have an exercise price per share of Class A common stock equal to $67.83 and will expire five years from the date of issuance. The February 2025 Offering closed on February 11, 2025. Both the February 2025 Pre-funded Warrants and the February 2025 Warrants meet the requirements for equity classification.

The Company received aggregate gross proceeds from the February 2025 Offering of approximately $5.0 million, before deducting estimated issuance costs of $0.6 million. Net proceeds of $4.4 million from the February 2025 Offering was recorded to additional paid-in-capital.

In connection with the February 2025 Offering, the Company entered into a securities purchase agreement with a single institutional investor, pursuant to which the Company agreed not to effect or enter into an agreement to effect any issuance by the Company or any of its subsidiaries of shares of common stock or common stock equivalents for a period of 30 days and would not effect or enter into an agreement to effect any issuance by the Company or any of its subsidiaries of shares of common stock or common stock equivalents (or a combination of units thereof) involving a variable rate transaction for a period of 6 months after February 11, 2025, subject to certain exceptions.

Also in connection with the February 2025 Offering, the Company entered into a Placement Agency Agreement on February 11, 2025, with the agency that assisted with the February 2025 Offering. The Company paid a cash placement agent commission equal to 7.0% of gross proceeds from the February 2025 Offering and issued warrants (the "February 2025 Placement Agent Warrants") to purchase 3,569 shares of Class A common stock at an exercise price of $77.07, exercisable immediately upon issuance. The February 2025 Placement Agent Warrants will expire five years from the date of issuance.

The Company estimated the fair value of the February 2025 Pre-funded Warrants based on the fair value of the Company's Class A common stock from the issuance date, less the $0.00001 exercise price.

Additionally, in connection with the February 2025 Offering, the Company agreed to amend the September 2024 Class A Warrants, September 2024 Class B Warrants (see discussion of the September 2024 Offering below), December 2024 Warrants (see discussion of the December 2024 Offering below), and Investor Warrants (collectively, the "Investor Modified Warrants") to purchase up to an aggregate of 40,017, 20,009, 44,818, and 20,009 shares of Class A common stock, respectively. Prior to amendment, the September 2024 Class A Warrants, September 2024 Class B Warrants, and Investor Warrants had an exercise price of $143.69 per share and the December 2024 Warrants had an exercise price of $108.53 per share. The September 2024 Class A Warrants, September 2024 Class B Warrants, December 2024 Warrants, and Investor Warrants had termination dates of March 17, 2030, March 17, 2026, December 18, 2029, and April 24, 2030, respectively. Upon amendment, each of the Investor Modified Warrants had a reduced exercise price of $67.83 per share and a termination date of February 11, 2030.

Subsequent to the February 2025 Offering, during the year ended December 31, 2025, the Company issued 54,560 shares of Class A common stock as a result of all of the February 2025 Pre-funded Warrants being exercised.

***Contingent Sponsor Earnout Shares***

In August 2021, the Company modified the terms of 116 shares of Class A common stock (the "Sponsor Earnout Shares"), such that all such shares will be forfeited if the share price of Class A common stock does not reach a volume-weighted average closing sale price of $156,188, two thirds of such shares will be forfeited if the share price of Class A common stock does not reach a volume-weighted average closing sale price of $187,425, and one third of such shares will be forfeited if the share price of Class A common stock does not reach a volume-weighted average closing sale price of $218,663, in each case, prior to the August 12, 2026. The Sponsor Earnout Shares may not be transferred without the Company's consent until the shares vest.

The Sponsor Earnout Shares are recorded within equity. Due to the contingently forfeitable nature of the shares, the Sponsor Earnout Shares are excluded from basic EPS calculations but are considered potentially dilutive shares for the purposes of diluted EPS (refer to Note 11).

***Legacy Stock Plans***

In May 2018, the Board of Directors of Momentus Inc. approved the 2018 Stock Plan (the "Initial Plan") that allowed for granting of incentive and non-qualified stock options ("NSOs") and restricted stock awards ("RSAs") to employees, directors, and consultants. The Initial Plan was terminated in November 2018. Awards outstanding under the Initial Plan continue to be governed by the terms of the Initial Plan.

In February and March 2020, the Board of Directors of Momentus Inc. approved the Amended and Restated 2018 Stock Plan (the "2018 Plan"). No additional grants have been made since 2020 and no new grants will be made from the 2018 Plan, however, the options issued and outstanding under the plan continue to be governed by the terms of the 2018 Plan. Forfeitures from the legacy plans become available under the 2021 Equity Incentive Plan, described below.

***2021 Equity Incentive Plan***

In 2021, the Company adopted the 2021 Equity Incentive Plan (the "2021 Plan"), under which 479 shares of Class A common stock were initially reserved for issuance. The 2021 Plan allows for the issuance of incentive stock options, NSOs, RSAs, stock appreciation rights ("SARs"), RSUs, and performance awards. The Board of Directors determines the period over which grants become exercisable. The 2021 Plan became effective immediately following the Closing. The 2021 Plan has an evergreen provision which allows for shares available for issuance under the plan to be increased on the first day of each fiscal year beginning with the 2022 fiscal year and ending on (and including) the first day of the 2031 fiscal year, in each case, in an amount equal to (i) three percent (3.0%) of the outstanding shares on the last day of the immediately preceding fiscal year or (ii) such number of shares determined by the Board of Directors.

***2021 Employee Stock Purchase Plan***

In connection with the Closing, the Company adopted the Employee Stock Purchase Plan (the "2021 ESPP"), under which 128 shares of Class A common stock were initially reserved for issuance. The 2021 ESPP provides a means by which eligible employees of the Company may be given an opportunity to purchase shares of Class A common stock at a discount as permitted under the Internal Revenue Code of 1986, as amended. The 2021 ESPP has an evergreen provision which allows for shares available for issuance under the plan to be increased on the first day of each fiscal year beginning with the 2022 fiscal year and ending on (and including) the first day of the 2031 fiscal year, in each case, in an amount equal to (i) half a percent (0.5%) of the outstanding shares on the last day of the calendar month prior to the date of such automatic increase or (ii) 128 shares. Participation in the 2021 ESPP has been suspended by the Board of Directors. The 2021 ESPP became effective immediately following the Closing. The Company has an outstanding liability pertaining to the 2021 ESPP of $4 thousand as of March 31, 2026, included in accrued expenses, for employee contributions to the 2021 ESPP, which will be refunded to participants due to the suspension of the plan.

**Note 11. Net Loss Per Share**

Net loss per share is provided in accordance with ASC Sub-Topic 260-10, *Earnings Per Share*. Basic earnings per share is computed by dividing net loss for the period by the weighted-average number of common shares outstanding during the period. Diluted earnings per share gives effect to all dilutive potential common shares outstanding during the period. It is computed by dividing undistributed earnings allocated to common stockholders for the period by the weighted average number of common shares outstanding during the period, plus the dilutive effect of outstanding preferred shares, options and unvested stock units, and warrants outstanding pursuant to the treasury stock method.

As the Company incurred a net loss for the three months ended March 31, 2026 and 2025, the inclusion of preferred stock, certain options, unvested stock units, warrants, convertible promissory notes, and contingent Sponsor Earnout Shares in the calculation of diluted earnings per share would be anti-dilutive and, accordingly, were excluded from the diluted loss per share calculation.

The following table summarizes potential common shares that were excluded as their effect is anti-dilutive:

---

| | | |
|:---|:---|:---|
| | **Three Months Ended<br>March 31,** | **Three Months Ended<br>March 31,** |
| | **2026** | **2025** |

Except as noted below, there have been no material changes to the legal proceedings disclosed in the Company's Annual Report on Form 10-K filed with the SEC on March 31, 2026. The Company continues to monitor the status of those proceedings, and developments will be disclosed in future filings as necessary.

*Founder Litigation* 

On March 5, 2026, Lev Khasis filed a verified complaint against the Company in Delaware Court of Chancery (Case No. 2026-0179-DG) seeking indemnification and advancement expenses from the Company in connection with the NSA and investigation by the SEC. Legal counsel to Khasis indicated that total expenses for which Mr. Khasis seeks indemnification is approximately $1.2 million plus legal expenses in connection with this suit. On April 6, 2026, the Company and Mr. Khasis entered into a confidential settlement and release agreement settling the claim for $0.4 million and the suit was dismissed with prejudice.

*Delaware Class Actions*

ANV Global Services Inc. ("ANV"), the insurer who issued a Side-A directors and officers liability insurance policy that provides coverage for the SRAC directors and officers, has asserted a claim against the Company for indemnification of certain former SRAC directors and officers in connection with a lawsuit captioned *In re Momentus, Inc. Stockholders Litigation*, No. 2023-0322, pending in the Delaware Court of Chancery (the "Consolidated Delaware Action"). ANV has requested reimbursement of $1.2 million for defense costs paid and contribution to a global settlement and has indicated it is prepared to file suit if a settlement is not reached. In April 2026, the Company and ANV agreed in principle to settle this matter for $1.0 million. The parties are negotiating the terms of a release and settlement agreement. The Company has made a settlement offer of $0.1 million in shares of Class A common stock to each of the three former SRAC directors and officers subject to the Consolidated Delaware Action. Discussions with ANV and the affected individuals are ongoing, but there can be no assurances a resolution will be achieved.

*Lease Restoration*

The Company entered a lease for office space at 1762 Automation Parkway, San Jose, California 95131 in December 2025. Previously, the Company leased a facility at 3901 North First Street, San Jose, California 95134 ("3901") that expired on March 31, 2026. The Company vacated 3901 on or before lease termination.

Under the sublease for 3901, the Company has an obligation to restore certain modifications prior to termination of the lease. The Company is unable to complete these restorations on that timeline and is negotiating with the sublandlord and the landlord regarding a financial settlement. The Company believes that it is probable that it will be required to pay a yet-to-be-determined amount of restoration costs. Total restoration costs should not exceed $0.7 million to $0.8 million based on construction proposals received by the Company and the sublandlord. However, the Company's obligation to restore certain alterations is subject to the landlord's having designated such alterations for removal at the time the landlord approved the Company's alteration plans. The Company has requested documentation from the landlord to evidence the Company's restoration obligations. The Company has not yet received such documentation. The Company has recorded an asset retirement obligation ("ARO") of $0.5 million related to these restoration costs, which it believes represents the low end of the range of possible loss.

The landlord has presented a construction proposal for $1.4 million and is claiming additional damages. The Company disputes the landlord's construction proposal and any additional damages.

On April 21, 2026, the landlord filed a complaint against the sublandlord in the Superior Court of the State of California County of Santa Clara seeking damages for breach of lease. As of the date of this filing, the Company has not received notice that the sublandlord has filed a cross-complaint against the Company.

**Note 12. Commitments and Contingencies** (cont.)

The Company is attempting to resolve these claims, but there can be no assurances a resolution will be achieved.

*Other Litigation and Related Matters*

These and other litigation matters may be time-consuming, divert management's attention and resources, cause the Company to incur significant defense and settlement costs or liability, even if we believe the claims asserted against us are without merit. We intend to vigorously defend against all such claims. Because of the potential risks, expenses and uncertainties of litigation, as well as claims for indemnity from various of the parties concerned, we may from time to time settle disputes, even where we believe that we have meritorious claims or defenses. Because litigation is inherently unpredictable, further compounded by various claims for indemnity which may or may not be fully insured, we cannot assure that the results of these actions, either individually or in the aggregate, will not have a material adverse effect on our consolidated operating results and financial condition.

From time to time, the Company may be a party to litigation and subject to claims incident to the ordinary course of business or in connection with the matters discussed above. Although the results of litigation and claims cannot be predicted with certainty, the Company currently believes that the final outcome of these matters will not have a material adverse effect on its business. Regardless of the outcome, litigation can have an adverse impact on the Company because of judgment, defense and settlement costs, diversion of management resources and other factors. At each reporting period, the Company evaluates whether or not a potential loss amount or a potential range of loss is probable and reasonably estimable under ASC 450-20. Legal fees are expensed as incurred.

*Accrued Loss Contingencies*

As of March 31, 2026, the Company has recorded accruals for certain probable loss contingencies and an ARO. These include $0.4 million accrued for the Khasis claim, $1.3 million for the ANV claim, $0.3 million for the 3901 sublease complaint, and a $0.5 million ARO recognized for the 3901 sublease. The $2.0 million of probable loss contingencies are recorded in litigation settlement contingency in the condensed consolidated balance sheets, and the $0.5 million ARO is recorded in other current liabilities in the condensed consolidated balance sheets. The Company believes these accruals are adequate based on information currently available.

**Note 13. Income Taxes** 

The Company's effective tax rate for the three months ended March 31, 2026 and 2025, respectively, was zero percent. The effective tax rate may vary significantly from period to period and can be influenced by many factors. These factors include, but are not limited to, changes to the statutory rates in the jurisdictions where the Company has operations and changes in the valuation of deferred tax assets and liabilities. The difference between the effective tax rate and the federal statutory rate of 21% primarily relates to certain nondeductible items, state and local income taxes, the absence of current income tax, and a full valuation allowance for deferred tax assets.

***One Big Beautiful Bill Act***

On July 4, 2025, a budget and reconciliation package known as the One Big Beautiful Bill Act (the "OBBBA") was signed into law in the United States. Among other provisions, the OBBBA amends U.S. tax law including the permanent extension of certain expiring provisions of the 2017 Tax Cuts and Jobs Act, modifications to the international tax framework and the restoration of favorable tax treatment for certain business provisions. The legislation has multiple effective dates, with certain provisions effective in 2025 and others implemented through 2027.

 **Note 14. Segment Information**

The Company operates as one operating segment. The Company's CODM is its Chief Executive Officer, who reviews financial information presented on a consolidated basis. The CODM uses consolidated net loss and net cash used in operations to assess financial performance and allocate resources. These financial metrics are used by the CODM to make key operating decisions, such as the allocation of budget between research and development and selling, general and administrative expenses and determination of cash from financing activities required.

**ITEM 2. Management's Discussion and Analysis of Financial Condition and Results of Operations**

*The following discussion and analysis provides information which our management believes is relevant to an assessment and understanding of our results of operations and financial condition. This discussion and analysis should be read together with our audited and unaudited financial statements and related notes appearing elsewhere in this Quarterly Report on Form 10-Q (this "Form 10-Q") and our Annual Report on Form 10-K filed with the SEC on March 31, 2026. This discussion and analysis should also be read together with our financial information for the period ended as of March 31, 2026. In addition to historical financial information, this discussion and analysis contains forward-looking statements that reflect our plans, estimates, and beliefs that involve risks, uncertainties and assumptions.

**Overview**

Momentus offers or plans to offer satellites, satellite buses, satellite technologies and components, including solar arrays, and transportation, communications and infrastructure services for commercial companies and to support the missions of U.S. and friendly governments. Government and commercial satellite operators and space technology companies and organizations are our target commercial customers. Momentus is also seeking business in support of U.S. government missions for departments and agencies like NASA and the U.S. Department of Defense.

We provide or plan to provide satellites, satellite buses, satellite technologies and components, including solar arrays, 3D printed propulsion tanks, integration of payload instruments, communication, tracking, and other satellite services, "last mile" satellite transportation, payload-hosting, on-orbit satellite refueling, on-orbit inspection, on-orbit satellite maintenance, de-orbiting, debris removal, and other satellite-to-satellite service offerings.

Our transportation service offering focuses on delivering our customers' satellites to precision orbits. To accomplish this, we partner with leading launch service providers, such as SpaceX, to "ride share" our customers' satellites from Earth to space on a midsized or large rocket. Customer satellites can also be carried aboard small launch vehicles for dedicated missions. Our OSVs would then provide "last mile" transportation services from the rocket's drop-off orbit to a custom orbit of the satellite operator's choosing. We believe this "hub-and-spoke" model has the potential to expand our customers' deployment options relative to what they would be able to achieve with ride share launch alone, while reducing their costs relative to what they could achieve with a dedicated small launch vehicle. Over time, we plan to begin introducing additional services beyond transportation and hosted payloads.

Our services are made possible by the space industry's rapid technological developments over the past two decades, driven predominantly by significant decreases in launch costs, as well as the advent of smaller, lower-cost satellites. The convergence of these trends has resulted in substantial growth in the commercial space market, rooted in higher accessibility for companies entering the new space economy that aim to offer communication, sensing, data processing and storage, Earth observation and data collection services, and other satellite services.

We anticipate potential considerable growth over the coming years in the space transportation segment as companies continue to seek versatile and low-cost ways to deliver single satellites to specific orbits or deploy their satellite constellations. We anticipate that the need for small satellite transportation to low-Earth orbit will continue to drive overall demand growth for space transportation services in the short-term as technology advancements continue to make space more accessible to new market entrants, although new applications beyond low-Earth orbit are also emerging. We also believe that over the next decade, new space-based businesses may emerge, for example the generation of solar energy in space, space manufacturing or space data processing. The advent of these new business models could substantially increase demand for space transportation and other space infrastructure services.

Beyond transportation, we anticipate that growth of the satellite constellations market may drive demand for our satellites, satellites buses, and technologies like solar arrays, 3D printed propulsion tanks, hosted payload, communication, tracking, and other satellite services, on-orbit satellite refueling, on-orbit inspection, on-orbit satellite maintenance, de-orbiting, debris removal, and other satellite-to-satellite service offerings, if we are

------

<u>[**Table of Contents**](#if15138d1252741479228fb3609acb72e_247)</u>

successful in executing on our business plan, including fully developing and validating our technology in space. Satellite constellations have relatively low lifespans and, in our view, will require maintenance, de-orbiting, and other general servicing with higher frequency.

Momentus offers the M-1000 satellite bus to both commercial and U.S. government customers. The market for satellite buses in this class is substantial and growing. The M-1000 satellite bus is based on the Vigoride OSV and has substantial commonality.

Momentus has launched five missions to date, deployed 17 customer satellites, and provided hosted payload services. Four of these missions involved operation of the Vigoride OSV in orbit. During these four Vigoride missions, the system and technology were tested repeatedly. Improvements based on lessons learned during these missions were rapidly incorporated. As a result of these four missions, the Vigoride OSV has been successfully demonstrated in space and accumulated significant flight heritage.

On March 30, 2026, the Vigoride 7 OSV produced by Momentus was launched to low Earth orbit with 10 payloads. This mission is scheduled to last several months and includes payloads from government and commercial customers, including DARPA, SpaceWERX which is the innovation organization of the U.S. Space Force, the U.S. Air Force Research Laboratory, NASA, and commercial customers.

**Components of Results of Operations**

***Service revenue***

We enter into contracts for 'last-mile' satellite and cargo delivery, payload hosting and in-orbit servicing options with customers that are primarily in the aerospace industry. The Company recognizes revenue (along with any other fees that have been paid) upon the earlier of the satisfaction of our performance obligation or when the customer cancels the contract. The Company also enters into contracts to perform analysis and provide engineering services to U.S. government organizations.

In general, our customers have the right to cancel their contracts with the understanding that they will forgo their deposits. If a customer cancels a contract before it is required to pay non-refundable deposits, we may not receive revenue from these orders, except for an initial deposit which is paid at the time the contract is signed.

During the three months ended March 31, 2026, the Company recognized $3.2 million of revenue primarily from the completion of performance obligations on hosted payload services and engineering services performed for U.S. government and engineering project services.

As of March 31, 2026, the Company had signed contracts with customers and had collected approximately $0.5 million in customer deposits, $0.1 million of which are recorded as non-current contract liabilities in our condensed consolidated balance sheets.

The Company estimates variable consideration at the most likely amount, which is included in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur. While the Company's standard contracts do not contain refund or recourse provisions that enable its customers to recover any non-refundable fees that have been paid, the Company may issue full or partial refunds to customers on a case-by-case basis as necessary to preserve and foster future business relationships and customer goodwill. Contracts to provide engineering services to U.S. government organizations generally have milestone payments subject to the variable consideration constraint. When a milestone is achieved, the Company updates its estimate of the transaction price to include the milestone payment and records a cumulative catch-up in revenue.

***Cost of revenue***

Cost of revenue consists primarily of expenses associated with third-party launch costs and direct headcount related to the related engineering work. The costs associated with OSVs are deferred to prepaid cost of revenues and amortized to cost of revenues upon release of payload. The current design and technology allow for a single use of the OSV.

***Research and development***

Research and development expenditures consist primarily of the cost of the following activities for developing existing and future technologies for our satellites, satellite technologies, and our OSV. Research and development activities include basic research, applied research, design, development, and related test program activities. Costs incurred for developing our technologies primarily include equipment and labor hours (both internal and

------

<u>[**Table of Contents**](#if15138d1252741479228fb3609acb72e_247)</u>

subcontractors). The Company also records launch costs related to the testing of its Vigoride vehicles as research and development costs.

As of March 31, 2026, we have expensed all research and development costs associated with developing and building our vehicles.

***Selling, general and administrative***

Selling, general and administrative expenses consist of human capital related expenses for employees involved in general corporate functions, including executive management and administration, accounting, finance, tax, legal, information technology, security, sales, marketing, and human resources; depreciation expense and rent relating to facilities, and equipment; professional fees; and other general corporate costs. Headcount-related expenses primarily include salaries, bonuses, equity compensation expense and benefits.

We also incur additional expenses as a result of operating as a public company, including expenses necessary to comply with the rules and regulations applicable to companies listed on a national securities exchange and related to compliance and reporting obligations pursuant to the rules and regulations of the SEC.

***Realized loss on disposal of assets***

Realized loss on disposal of assets consists of disposals of machinery and equipment with carrying values in excess of proceeds received, if any.

***Interest income***

Interest income consists of interest earned by the Company on investment holdings in interest bearing bank accounts.

***Interest expense***

Interest expense includes interest incurred by the Company related to our loan payables as well as the amortization of warrant discount and debt issuance costs.

***Gain (Loss) on debt extinguishment***

Gains or losses on extinguishment of debt are recognized for unamortized debt premiums, discounts and issuance costs as well as any fees paid to the lender in relation to the extinguishment.

***Other income (expense)***

Other income (expense) primarily relates to non-recurring fees incurred in conjunction with impairment or write-off charges and other immaterial items.

***Income tax provision***

We are subject to income taxes in the United States. Our income tax provision consists of an estimate of federal and state income taxes based on enacted federal and state tax rates, as adjusted for allowable credits, deductions, uncertain tax positions, changes in the valuation of our deferred tax assets and liabilities, and changes in tax laws.

The effective tax rate may vary significantly from period to period and can be influenced by many factors. These factors include, but are not limited to, changes to the statutory rates in the jurisdictions where the Company has operations and changes in the valuation of deferred tax assets and liabilities. The difference between the effective tax rate and the federal statutory rate of 21% primarily relates to certain nondeductible items, state and local income taxes and a full valuation allowance for deferred tax assets.

***Service revenue***

Service revenue increased $2.9 million, from $0.3 million for three months ended March 31, 2025 to $3.2 million for the three months ended March 31, 2026. The increase was driven by two factors. First, the Company recognized $1.6 million of revenue from hosted payload services related to the Vigoride 7 mission during the three months ended March 31, 2026, compared to no hosted payload services revenue during three months ended March 31, 2025. Second, engineering project services revenue increased $1.4 million, from $0.2 million for the three months ended March 31, 2025, to $1.6 million for three months ended March 31, 2026, primarily due to expanded work for NASA and continued work under the DARPA NOM4D and DARPA BRIDGES programs. The remaining components of service revenue consist of forfeited customer deposits upon contract expiration, which were zero and $0.1 million for the three months ended March 31, 2026 and 2025, respectively.

***Cost of revenue***

Cost of revenue for the three months ended March 31, 2026, was primarily due to the launch cost allocated to customer payloads on the Vigoride 7 mission.

***Research and development expenses***

Research and development expenses increased from $1.9 million in the three months ended March 31, 2025, to $4.2 million in the three months ended March 31, 2026. The increase was primarily due to a $0.9 million increase in payroll costs, a $0.6 million increase in subcontractor costs, and a $0.9 million increase in other miscellaneous fees, such as information technology and facilities overhead allocation.

***Selling, general and administrative expenses***

Selling, general and administrative expenses increased from $4.6 million in the three months ended March 31, 2025, to $6.3 million in the three months ended March 31, 2026. The increase is primarily due to (i) an increase in legal expenses of $1.5 million, and (ii) a $0.6 million increase in other miscellaneous fees, such as insurance and subscriptions. These increases were partially offset by (i) a $0.2 million decrease in payroll related expenses and (ii) a decrease in consulting and professional services of $0.2 million.

***Realized loss on disposal of assets***

The increase in realized loss on disposal of assets for the three months ended March 31, 2026, was due to losses from the write-off of machinery and equipment. There was no loss on disposal recognized during the three months ended March 31, 2025.

------

<u>[**Table of Contents**](#if15138d1252741479228fb3609acb72e_247)</u>

***Interest income***

Interest income increased from $4 thousand for three months ended March 31, 2025, to $0.1 million for the three months ended March 31, 2026, as the Company invested more in money market funds.

***Interest expense***

Interest expense increased from $(0.2) million for the three months ended March 31, 2025, to $0.6 million for the three months ended March 31, 2026. The interest increase is primarily due to increase in cash interest accrual and amortization of the debt discount on the SIV Convertible Notes and the September 2025 Convertible Note, partially offset by amortization of the debt premium on the SIV Convertible Notes. See Note 8 for additional information.

***Gain on debt extinguishment***

The gain on extinguishment of debt recognized for the three months ended March 31, 2025, was due to the amendment of the SIV Convertible Notes. See Note 8 for additional information. There was no gain or loss on extinguishment recognized during the three months ended March 31, 2026.

***Other income (expense)***

Other income increased to $0.01 million during the three months ended March 31, 2026, from other expense of $0.2 million during the three months ended March 31, 2025, primarily due to resolution of a prior obligation of the Company.

**Liquidity and Capital Resources**

***Capital Resources and Recent Financing Transactions***

In prior periods, the Company disclosed that conditions and events raised substantial doubt regarding its ability to continue as a going concern. As described in Note 1 in the notes to our condensed consolidated interim financial statements included elsewhere in this Form 10-Q, management has concluded that the financings completed since December 31, 2025, including approximately $16.7 million of net cash provided by financing activities during the three months ended March 31, 2026, and the $5.0 million private placement completed subsequent to quarter-end, together with the Company's current cash position, expected operating plan, and forecasted liquidity needs, are sufficient to fund operations and meet obligations for at least the twelve-month period following the issuance date of these condensed consolidated interim financial statements. Accordingly, substantial doubt no longer exists.

The Company's forecasts and operating plans are subject to risks and uncertainties as discussed above under *Cautionary Note Regarding Forward-Looking Statements*, and actual results could differ from management's expectations.

Vigoride 7 customers during the three months ended March 31, 2026. Additionally, the Company had a change in operating assets and liabilities of $1.5 million during the three months ended March 31, 2026.

Net cash used in operating activities for the three months ended March 31, 2025, was $4.2 million, driven primarily by headcount costs, research and development activities, legal expenses, and professional fees, as well as net cash changes in operating assets and liabilities.

Headcount related payroll costs, excluding stock-based compensation of $1.1 million, were $1.6 million. Professional fees of $2.1 million included $0.4 million in legal fees. Office overheads and other general corporate expenses were $1.2 million, which includes insurance costs of $0.3 million. Research and Development activity expenses, including materials, components, and subcontractor costs were $0.3 million.

Additionally, the Company had a change in operating assets and liabilities of $0.9 million during the three months ended March 31, 2025.

***Investing Activities***

Net cash used in investing activities was $0.2 million for three months ended March 31, 2026, which consisted of purchases of machinery and equipment.

***Financing Activities***

Net cash provided by financing activities was $16.7 million for the three months ended March 31, 2026, primarily due to gross proceeds of approximately $18.3 million received shares sold under the ATM Sales Agreement and the January 2026 Offering. These gross proceeds were partially offset by (i) principal repayments of $0.8 million on the SIV Convertible Notes and the September 2025 Convertible Note and (ii) $0.8 million in issuance costs related to common stock and related warrants.

Net cash provided by financing activities was $6.0 million for the three months ended March 31, 2025, primarily due to gross proceeds of approximately (i) $5.0 million received from the February 2025 Offering and (ii) $2.1 million received from the March 2025 Warrant Inducement. These gross proceeds were partially offset by (i) principal repayments of $0.3 million under the SIV Convertible Notes, and (ii) $0.8 million in issuance costs related to common stock and related warrants.

***Funding Requirements***

We expect our cash consumption to continue in connection with our ongoing activities.

Specifically, our operating expenses will continue as we:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• continue to refine and operate our corporate infrastructure, people, processes and systems;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• pursue sales and marketing activities for our product and services;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• pursue further research and development related to developing our satellites and satellite technology;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• seek regulatory approvals for operation of our satellites and vehicles;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• actively manage our workforce, including right sizing in personnel;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• maintain, expand and protect our intellectual property portfolio;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• comply with public company reporting requirements; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• defend against litigation.

Changing circumstances may cause us to expend capital significantly faster than we currently anticipate, or we may need to spend more money than currently expected because of circumstances beyond our control. We may be required to seek additional equity or debt financing. In the event that additional financing is required from outside sources, we may not be able to raise it on terms acceptable to us, or at all. If we are unable to raise additional capital when desired, our business, results of operations, and financial condition would be adversely affected.

**Commitments and Contingencies**

We are a party to leases primarily for facilities (e.g., office buildings, warehouses, and spaceport) under non-cancellable operating leases. Refer to Note 6.

------

<u>[**Table of Contents**](#if15138d1252741479228fb3609acb72e_247)</u>

We enter into purchase obligations in the normal course of business. These obligations include purchase orders and agreements to purchase goods or services that are enforceable, legally binding, and have significant terms and minimum purchases stipulated. Refer to Note 12.

In addition, we enter into agreements in the normal course of business with vendors for research and development services and outsourced services, which are generally cancellable upon written notice.

**Off-Balance Sheet Arrangements**

We do not engage in any off-balance sheet activities or have any arrangements or relationships with unconsolidated entities, such as variable interest, special purpose, and structured finance entities.

**Critical Accounting Policies and Estimates**

Our discussion and analysis of our financial condition and results of operations are based upon our condensed consolidated interim financial statements, which have been prepared in accordance with GAAP. The preparation of our condensed consolidated interim financial statements and related disclosures requires us to make estimates, assumptions and judgments as of the balance sheet date that affect the reported amounts of assets, liabilities, revenues, costs and expenses and related disclosures. Our actual results may differ from these estimates under different assumptions and conditions. In addition to our critical accounting policies below, see Note 2 in the notes to our condensed consolidated interim financial statements included elsewhere in this Form 10-Q.

***Revenue Recognition***

The Company enters into short-term contracts for 'last-mile' satellite and cargo delivery (transportation services), payload hosting and in-orbit servicing options with customers that are primarily in the aerospace industry. For its transportation service arrangements, the Company has a performance obligation of delivering the customers' payload to its designated orbit and recognizes revenue (along with any other fees that have been paid) at a point in time, upon satisfaction of this performance obligation. Additionally, for its in-orbit service arrangements, the Company provides a multitude of services during the mission to its customers. The Company recognizes revenue for these in-orbit services ratably over time on a straight-line basis. The Company enters into contracts to perform services for U.S. government customers. The Company recognizes revenue for these services in accordance with the terms of these contracts.

We account for customer contracts in accordance with ASC Topic 606, which includes the following five-step model:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Identification of the contract, or contracts, with a customer.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Identification of the performance obligations in the contract.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Determination of the transaction price.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Allocation of the transaction price to the performance obligations in the contract.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Recognition of revenue when, or as, the Company satisfies a performance obligation.

The Company estimates variable consideration at the most likely amount, which is included in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur. While the Company's standard contracts do not contain refund or recourse provisions that enable its customers to recover any non-refundable fees that have been paid, the Company may issue full or partial refunds, or concessions on future services to customers on a case-by-case basis as necessary to preserve and foster future business relationships and customer goodwill.

The Company's satellite and cargo delivery services (transportation services) are considered a performance obligation, to transport the customers' payload to a specified orbit in space. We recognize revenue for these services at a point in time, when control is transferred, which is considered to be upon the release of the customers' payload into its specified orbit. We will calculate the weight distribution of each transfer vehicle at the customer level, and we will estimate the delivery date for each customer's payload based on the relative weight of payloads released to determine the point in time to recognize revenue for each payload release.

The Company's in-orbit services consist of a collection of interdependent and integrated services which are not considered distinct from one another and may vary depending on the specific needs of the Customer and mission. Revenue for these in-orbit services is recognized ratably over time on a straight line basis.

------

<u>[**Table of Contents**](#if15138d1252741479228fb3609acb72e_247)</u>

The Company's engineering project services to U.S. government organizations generally have specific payment attached to each milestone. When a milestone is achieved, the Company submits services performed for approval. Once approval is received, the Company invoices and collects on the milestone completed.

In periods in which we recognize revenue, we will disclose the amounts of revenue recognized that was included as a contract liability balance at the beginning of the reporting period in accordance with ASC Sub-Topic 606-10-50-8(b).

***Loss Contingencies***

We are subject to the possibility of various loss contingencies arising in the ordinary course of business, including product-related and other litigation. We consider the likelihood of loss or impairment of an asset or the incurrence of a liability, as well as our ability to reasonably estimate the amount of loss in determining loss contingencies. An estimated loss contingency is accrued when it is probable that an asset has been impaired or a liability has been incurred and the amount of loss can be reasonably estimated. We regularly evaluate current information available to us to determine whether such accruals should be adjusted and whether new accruals are required. Refer to Note 12.

***Deferred Fulfillment and Prepaid Launch Costs***

We prepay for certain launch costs to third-party providers that will carry the OSV or satellite to orbit. Prepaid costs allocated to the delivery of a customer's payload are classified as deferred fulfillment costs. Prepaid costs allocated to our payload are classified as prepaid launch costs. These costs are then recognized as cost of revenues upon release of the customer's payload and our payload, respectively.

***Contract Liabilities***

Customer deposits collected prior to the release of the customer's payload into its specified orbit are recorded as current and non-current contract liabilities in our condensed consolidated balance sheets as the amounts received represent a prepayment for the satisfaction of a future performance obligation that has not yet commenced. Some customer deposits are non-refundable. Each non-refundable deposit is determined to be a contract liability upon cash collection. Prior to making this determination, we ensure that a valid contract is in place that meets the definition of the existence of a contract in accordance with ASC Sub-Topic 606-10-25-1 and 2.

***Stock-based Compensation***

We have various stock incentive plans under which incentive and NSOs and RSAs are granted to employees, directors, and consultants. All stock-based payments to employees, including grants of employee stock options are recognized in the condensed consolidated interim financial statements based on their respective grant date fair values.

We recognize stock-based compensation expense using a fair value-based method for costs related to all stock-based payments. We estimate the fair value of stock-based payments on the date of grant using the Black-Scholes-Merton option pricing model (or "BSM"). The model requires management to make a number of assumptions, including expected volatility of our stock, expected life of the option, risk-free interest rate, and expected dividends. The fair value of the stock is expensed over the related service period which is typically the vesting period. The stock-based compensation expense that is reported in our condensed consolidated interim financial statements is based on awards that are expected to vest. We account for forfeitures as they occur.

Estimating the fair value of equity awards as of the grant date using valuation models, such as the BSM option pricing model, is affected by assumptions regarding a number of variables as disclosed above, and any changes in the assumptions can materially affect the fair value and ultimately how much stock-based compensation expense is recognized. These inputs are subjective and generally require significant analysis and judgment to develop.

***Debt and Equity Financings***

We have entered into various debt and equity financing arrangements, including convertible promissory notes, warrants, pre-funded warrants, and an equity line of credit agreement. Accounting for these instruments requires significant management judgment, including the determination of whether warrants and embedded conversion options meet the criteria for equity classification or must be accounted for as liabilities. Certain warrants are accounted for as liabilities and are remeasured at fair value each reporting period using Level 3 valuation techniques, with changes in fair value recognized in the consolidated statements of operations. The fair value calculations involve assumptions regarding stock price volatility, expected term, and risk-free interest rates. Changes in these assumptions could materially affect the Company's financial statements. Refer to Notes 8 and 9 to the condensed consolidated interim financial statements for additional information.

<u>[**Table of Contents**](#if15138d1252741479228fb3609acb72e_247)</u>

***Income Taxes***

We account for income taxes in accordance with authoritative guidance, which requires the use of the asset and liability method. Under this method, deferred income tax assets and liabilities are determined based upon the difference between the financial statement carrying amounts and the tax basis of assets and liabilities and are measured using the enacted tax rate expected to apply to taxable income in the years in which the differences are expected to be reversed.

Significant judgment is required in determining any valuation allowance recorded against deferred tax assets. In assessing the need for a valuation allowance, management considers all available evidence, including past operating results, estimates of future taxable income, and the feasibility of tax planning strategies.

In the event that management changes its determination as to the amount of deferred tax assets that can be realized, we will adjust our valuation allowance with a corresponding impact to the provision for income taxes in the period in which such determination is made.

ASC Topic 740-10 requires companies to determine whether it is "more likely than not" that a tax position will be sustained upon examination by the appropriate taxing authorities before any tax benefit can be recorded in the condensed consolidated interim financial statements. It also provides guidance on the recognition, measurement, classification and interest and penalties related to uncertain tax positions. The amount that is ultimately sustained for an individual uncertain tax position or for all uncertain tax positions in the aggregate could differ from the amount that is initially recognized.

**Recent Accounting Pronouncements**

From time to time, new accounting pronouncements are issued by the FASB or other standard-setting bodies that are adopted by us as of the specified effective date. Unless otherwise discussed, we believe that the impact of recently issued standards that are not yet effective will not have a material impact on our financial position or results of operations upon adoption.

Please refer to Note 2 in the notes to our condensed consolidated interim financial statements included elsewhere in this Form 10-Q for a description of recently adopted accounting pronouncements and recently issued accounting pronouncements not yet adopted, the timing of their adoptions and our assessment, to the extent we have made one, of their potential impact on our consolidated financial condition and results of operations.

**ITEM 3. Quantitative and Qualitative Disclosures about Market Risk**

We are exposed to a variety of market and other risks, including the effects of changes in interest rates, and inflation, as well as risks to the availability of funding sources, hazard events, and specific asset risks.

*Interest Rate Risk*

The market risk inherent in our financial instruments and our financial position represents the potential loss arising from adverse changes in interest rates. As of March 31, 2026, we had cash and cash equivalents of $23.5 million, which were primarily invested in highly liquid investments purchased with a remaining maturity of three months or less. However, due to the short-term maturities and the low-risk profile of our investments, an immediate 10% change in interest rates would not have a material effect on the fair value of our cash and cash equivalents.

*Foreign Currency Risk*

There were no material foreign currency transactions for the three months ended March 31, 2026 and 2025.

**ITEM 4. Controls and Procedures**

*Evaluation of Disclosure Controls and Procedures*

The Company maintains disclosure controls and procedures ("Disclosure Controls") as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act that are designed to provide reasonable assurance that information required to be disclosed in our Exchange Act reports is recorded, processed, summarized and reported within the time periods specified in the SEC rules and forms, and that such information is accumulated and communicated to management, including the Chief Executive Officer ("CEO") and Chief Financial Officer ("CFO"), as appropriate to allow timely decisions regarding required disclosure.

In designing and evaluating the Disclosure Controls, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control

------

<u>[**Table of Contents**](#if15138d1252741479228fb3609acb72e_247)</u>

objectives and management was required to apply judgment in evaluating its controls and procedures. All internal control systems, no matter how well designed, have inherent limitations, including the possibility of human error and the circumvention of overriding controls.

In connection with the preparation of this report, our management, under the supervision and with the participation of our CEO and CFO, conducted an evaluation of the effectiveness of the design and operation of our Disclosure Controls as of March 31, 2026. Based on this evaluation, the CEO and CFO concluded that the Company's Disclosure Controls were effective as of March 31, 2026.

Our management, including our CEO and CFO, has concluded that the condensed consolidated interim financial statements included in this Quarterly Report on Form 10-Q fairly present, in all material respects, our financial condition, results of operations and cash flows for the periods presented in conformity with GAAP.

*Changes in Internal Control over Financial Reporting*

There were no changes in our internal control over financial reporting during the fiscal quarter ended March 31, 2026 which were identified in connection with management's evaluation required by paragraph (d) of Rules 13a-15 and 15d-15 under the Exchange Act that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

**ITEM 1A. Risk Factors**

In addition to the other information set forth in this report, you should carefully consider the risk factors discussed in "*Risk Factors*" in our most recent Annual Report on Form 10-K filed by the Company on March 31, 2026, which could materially affect our business, financial condition or future results. The risks described below and in our Annual Report on Form 10-K filed by the Company on March 31, 2026, are not the only risks facing our Company. Additional risks and uncertainties not currently known to us or that we currently deem immaterial also may materially adversely affect our business, financial condition, operating results, and/or cash flows.

**ITEM 2. Unregistered Sales of Equity Securities and Use of Proceeds**

***Debt Settlements***

In March 2026, the Company issued 5,723 shares of its Class A common stock to a vendor to settle outstanding debts of $0.1 million.

Shares of the Company's Class A common stock issued in the transaction described herein are exempt from registration under the Securities Act in reliance on Section 4(a)(2) of the Securities Act. The vendor is an "accredited investor" as defined in Regulation D or "sophisticated investor" and was acquiring the shares for investment only and not with a view towards, or for resale in connection with, the public sale or distribution thereof. Accordingly, the shares of the Company's Class A common stock were not registered under the Securities Act and may not be offered or sold in the United States absent registration or an exemption from registration under the Securities Act and any applicable state securities laws.

**ITEM 3. Defaults Upon Senior Securities**

None.

**ITEM 4. Mine Safety Disclosures**

None.

**ITEM 5. Other Information**

***Rule 10b5-1 Trading Plans***

**THE SARBANES-OXLEY ACT OF 2002** 

I, John Rood, certify that:

1I have reviewed this Quarterly Report on Form 10-Q of Momentus Inc.;

2Based on my knowledge, this report does not contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements made, in light of the circumstances under which such statements were made, not misleading with respect to the period covered by this report;

3Based on my knowledge, the financial statements, and other financial information included in this report, fairly present in all material respects the financial condition, results of operations and cash flows of the registrant as of, and for, the periods presented in this report;

4The registrant's other certifying officer and I are responsible for establishing and maintaining disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) and internal control over financial reporting (as defined in Exchange Act Rules 13a-15(f) and 15d-15(f)) for the registrant and have:

5The registrant's other certifying officer and I have disclosed, based on our most recent evaluation of internal control over financial reporting, to the registrant's auditors and the audit committee of the registrant's board of directors (or persons performing the equivalent functions):

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;a)all significant deficiencies and material weaknesses in the design or operation of internal control over financial reporting which are reasonably likely to adversely affect the registrant's ability to record, process, summarize and report financial information; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;b)any fraud, whether or not material, that involves management or other employees who have a significant role in the registrant's internal control over financial reporting.
