Accounting Policies [Abstract]

Summary of Significant Accounting Policies

Note 2. Summary of Significant Accounting Policies

Principles of Consolidation

The consolidated 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 consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts in the consolidated financial statements and accompanying notes. Management bases its estimates on historical experience and 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 consolidated 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 December 31, 2025 and 2024, the Company maintained restricted cash of $0.1 million and zero, respectively.

Accounts Receivable

Accounts receivable as of December 31, 2024, represent amounts primarily due from the Defense Advanced Research Project Agency (“DARPA”) to provide support to the DARPA Novel Orbital and Moon Manufacturing, Materials, and Mass-efficient Design (“NOM4D”) program, including arranging launch services, payload integration, and in-orbit hosting of the payload for a complex in-space assembly mission. 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 December 31, 2025 and 2024, 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 December 31, 2025 and 2024, the Company had deferred fulfillment and prepaid launch costs of $6.3 million and $2.6 million, respectively, with $5.1 million and zero recorded within prepaids and other current assets, respectively, and $1.2 million and $2.6 million recorded within other non-current assets in our 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.

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 consolidated 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 consolidated 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:

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

•Identification of the performance obligations in the contract.

•Determination of the transaction price.

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

•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 years ended December 31, 2025 and 2024, the Company recorded $0.9 million and $1.8 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 December 31, 2025 and 2024, the Company had customer deposit balances of $4.2 million and $2.2 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 consolidated balance sheets. Included in the collected amount as of December 31, 2025 and 2024, are $0.1 million and $1.9 million, respectively, of non-current deposits.

During the year ended December 31, 2025, the Company recognized $1.1 million of revenue primarily due to engineering services performed under the DARPA NOM4D and DARPA BRIDGES programs, payment under the Space Development Agency HALO program, and forfeited customer deposits primarily related to expired options. Of the $1.1 million of revenue recognized, $0.2 million was derived from the December 31, 2024, contract liability balance. During the year ended December 31, 2024, the Company recognized $2.1 million of revenue due to engineering services performed on the Space Development Agency milestone two agreement and forfeited customer deposits primarily related to expired options. Of the $2.1 million of revenue recognized, $0.3 million was derived from the December 31, 2023, contract liability balance.

The disaggregation of revenue by type is as follows:


	Year Ended December 31,
(in thousands)		2025		2024


Forfeited customer deposits		$	162	$	307
Engineering project services		948		1,807
Total revenue		$	1,110	$	2,114

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:

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

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

•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 years ended December 31, 2025 and 2024.

As of December 31, 2025, 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, 2023 and 2024	$	—
Issuance	—
Change in fair value	164
Balance, December 31, 2025	$	164

As of December 31, 2025, the Company has the following liabilities measured at fair value on a recurring basis:

•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.

•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 as of December 31, 2025, were as follows:


Expected term (years)	0.96
Stock price	$	4.87
Volatility	45.00		%
Risk-free rate	3.49		%
Dividend yield	—		%

•Fair Value Option (“FVO”) permitted under ASC Topic 825 for the May 2025 Loan. The May 2025 Loan is classified within Level 3 of the fair value hierarchy as the Company is using a convertible bond pricing model to calculate fair value. Prior to extinguishment in 2025, the May 2025 Loan was measured at fair value based on the expected settlement amount of the loan.

•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. 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 ELOC Pre-funded Warrants are classified as a liability under ASC Topic 815 and measured at fair value. The ELOC Pre-funded Warrants are classified within Level 3 of the fair value hierarchy because the number of shares issuable upon exercise is subject to contingent variability, which requires management’s estimate of the probability that the trigger will not occur. The Company estimated the fair value of the warrants based on the per share fair value of the Class A common stock at issuance and upon exercise, less the $0.00001 exercise price, multiplied by the current (non-contingent) number of shares.

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 years ended December 31, 2025 and 2024.

The change in fair values of liabilities subject to recurring remeasurement were as follows:


(in thousands)	Warrant Liability (Level 3)		May 2025 Loan (Level 3)		May 2025 Convertible Note (Level 3)		AIR Warrants (Level 3)		ELOC Pre-funded Warrants (Level 3)

Warrant Liability

Certain of the Company’s private warrants and stock purchase warrants are recorded as derivative liabilities pursuant to ASC Topic 815, including the ELOC Pre-funded Warrants, or liabilities pursuant to ASC Topic 480, including the AIR Warrants, and are classified within Level 3 of the fair value hierarchy as the Company uses significant unobservable inputs is using the BSM option pricing model, or other appropriate valuation techniques, to calculate fair value. See Note 9 for additional information. Significant unobservable inputs, prior to the Company’s stock being publicly listed, included stock price, volatility and expected term. At the end of each reporting period, changes in fair value during the period are recognized as components of other income within the consolidated statements of operations. The Company will continue to adjust the warrant liability for changes in fair value until the earlier of (i) the exercise or expiration of the warrants or (ii) the redemption of the warrants, at which time the warrants will be reclassified to additional paid-in capital within the consolidated statements of stockholders' equity (deficit).

The warrants issued by Momentus Inc. prior to the Business Combination were exercised in connection with the Business Combination and as a result, the Company performed a fair value measurement of those warrants on the Closing and recorded the change in the instruments’ fair values prior to converting them to equity. The warrants assumed by the Company as a result of the Business Combination remain outstanding.

Public and Private Warrants

Prior to the Business Combination, SRAC issued 903 private placement warrants (“Private Warrants”) and 691 public warrants (“Public Warrants” and, collectively with the Private Warrants, the “Public and Private Warrants”). Each whole warrant entitles the holder to purchase one share of the Company’s Class A common stock at a price of

$143,693 per share, subject to adjustments and will expire five years after the Business Combination or earlier upon redemption or liquidation.

The Private Warrants do not meet the derivative scope exception and are accounted for as derivative liabilities. Specifically, the Private Warrants contain provisions that cause the settlement amounts to be dependent upon the characteristics of the holder of the warrant which is not an input into the pricing of a fixed-for-fixed option on equity shares. Therefore, the Private Warrants are not considered indexed to the Company’s stock and should be classified as a liability. Since the Private Warrants meet the definition of a derivative, the Company recorded the Private Warrants as liabilities on the consolidated balance sheets at fair value upon the Closing, with subsequent changes in the fair value recognized in the consolidated statements of operations at each reporting date. The fair value of the Private Warrants was measured using the BSM option pricing model at each measurement date.

In addition, the Public Warrants are accounted for as equity classified by the Company. On consummation of the Business Combination, the Company recorded equity related to the Public Warrants of $20.2 million, with an offsetting entry to additional paid-in capital. Similarly, on the consummation of the Business Combination, the Company recorded a liability related to the Private Warrants of $31.2 million, with an offsetting entry to additional paid-in capital.

The Company does not use derivative instruments to hedge exposures to cash flow, market, or foreign currency risks. The Company evaluates all of its financial instruments, including issued stock purchase warrants, to determine if such instruments are derivatives or contain features that qualify as embedded derivatives, pursuant to ASC Topic 815, at the initial recognition.

Other than the Public and Private Warrants noted above, the Company also had other warrants issued and outstanding which were recognized as derivative liabilities in accordance with ASC Topic 815 until they were fully exercised. Accordingly, the Company recognized the warrant instruments as liabilities at fair value and adjusts the instruments to fair value at each reporting period until exercised. The fair value of the warrant liabilities issued were initially measured using the BSM option pricing model, or other appropriate valuation techniques, and were subsequently remeasured at each reporting period with changes recorded as a component of other income in the Company’s consolidated statements of operations. Derivative warrant liabilities are classified as non-current as their liquidation is not reasonably expected to require the use of current assets or require the creation of current liabilities. See Note 9 for additional information.

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 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 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 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 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 their estimated fair value. During the years ended December 31, 2025 and 2024, 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 consolidated 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 years ended December 31, 2025 and 2024.

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 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.

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 $1.1 million of revenue recognized by the Company during the year ended December 31, 2025, 10% 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.

In October 2023, the FASB issued ASU 2023-06, Disclosure Improvements: Codification Amendments in Response to the SEC’s Disclosure Update and Simplification Initiative (“ASU 2023-06”). The amendments in this ASU are expected to clarify or improve disclosure and presentation requirements of a variety of ASC topics by aligning them with the SEC’s regulations. ASU 2023-06 will become effective for each amendment on the effective date of the SEC’s corresponding disclosure rule changes, which must occur by June 30, 2027, or the amendments will not take effect. The Company does not anticipate that the adoption of ASU 2023-06 will have a material impact on its consolidated financial statements and related disclosures.

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 consolidated 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 consolidated financial statements and related disclosures.

In December 2025, the FASB issued ASU No. 2025-12, Codification Improvements (“ASU 2025-12”), which refines existing guidance to further enhance the interpretation and application of the Codification. The guidance is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2026. The amendments in ASU 2025-12 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 2025-12 will have a material impact on its consolidated financial statements and related disclosures.

Recently Adopted Accounting Standards

In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, requiring public entities to disclose information about their reportable segments’ significant expenses and other segment items on an interim and annual basis. Public entities with a single reportable segment are required to apply the disclosure requirements in ASU 2023-07, as well as all existing segment disclosures and reconciliation requirements in ASC Topic 280 on an interim and annual basis. The Company adopted ASU 2023-07 during the year ended December 31, 2024. See Note 15, Segment and Geographic Information, in the accompanying notes to the consolidated financial statements for further detail.

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures (“ASU 2023-09”), that addresses requests for improved income tax disclosures from investors that use the financial statements to make capital allocation decisions. Public entities must adopt the new guidance for fiscal years beginning after December 15, 2024. The amendments in ASU 2023-09 should be applied on a prospective basis. Retrospective application and early adoption is permitted. The Company adopted ASU 2023-09 on January 1, 2025, on a retrospective basis, which did not have a material impact on its consolidated financial statements and related disclosures.

In March 2024, the FASB issued ASU 2024-02 which removes references to the Board’s concepts statements from the FASB ASC. The ASU is part of the Board’s standing project to make “Codification updates for technical corrections such as conforming amendments, clarifications to guidance, simplifications to wording or the structure of guidance, and other minor improvements.” The amendments in this Update are effective for public business entities for fiscal years beginning after December 15, 2024. For all other entities, the amendments are effective for fiscal years beginning after December 15, 2025. The Company adopted ASU 2024-02 on January 1, 2025, which did not have a material impact on its consolidated financial statements and related disclosures.

Nature of Operations	12 Months Ended
Nature of Operations	Dec. 31, 2025
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Nature of Operations	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 four missions to date, deployed 17 customer satellites, and provided hosted payload services. Three of these missions involved operation of the Vigoride Orbital Service Vehicle (“OSV”) in orbit. During these three 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 three missions, the Vigoride OSV has been successfully demonstrated in space and accumulated significant flight heritage. The Company has produced its next OSV, Vigoride 7, that it intends to utilize on a 2026 mission. In addition to the Vigoride OSV, Momentus is now 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. Business Combination On August 12, 2021, the Company consummated a merger pursuant to the terms of the Agreement and Plan of Merger, dated October 7, 2020, and as amended on March 5, 2021, April 6, 2021, and June 29, 2021 (the “Merger Agreement”), by and among Stable Road Acquisition Corp (“SRAC”), Project Marvel First Merger Sub, Inc., a Delaware corporation and a direct, wholly-owned subsidiary of SRAC (“First Merger Sub”), and Project Marvel Second Merger Sub, LLC, a Delaware limited liability company and a direct, wholly-owned subsidiary of SRAC (“Second Merger Sub”), pursuant to which First Merger Sub merged with and into Momentus Inc., a Delaware corporation (“Legacy Momentus”) with Legacy Momentus as the surviving corporation of the First Merger Sub, and immediately following which Legacy Momentus merged with and into the Second Merger Sub, with the Second Merger Sub as the surviving entity (the “Business Combination”). In connection with the closing of the Business Combination (“Closing”), the Company changed its name from Stable Road Acquisition Corp. to Momentus Inc., and Legacy Momentus changed its name to Momentus Space, LLC. The Business Combination was accounted for as a reverse recapitalization under ASC Topic 805, Business Combinations, with SRAC and its two wholly-owned subsidiaries. The Company received gross proceeds of $247.3 million upon the Closing. Public and private warrants of SRAC were assumed by the Company as a result of the Business Combination. Going Concern The accompanying consolidated 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 consolidated financial statements are issued and will be able to realize its assets and discharge its liabilities and commitments in the normal course of business. Pursuant to ASC Sub-Topic 205-40, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern, in connection with the preparation of the consolidated financial statements for the year ended December 31, 2025, management concluded that, without taking into consideration the potential mitigating effect of management’s plans that have not been fully implemented or are not within control of the Company, there are conditions or events, considered in the aggregate, that raise substantial doubt about the Company’s ability to fund its regular operations, scaling of commercial production, and maintain its existing services and products as a going concern for one year from the date these consolidated financial statements are issued. Management’s plans in the event the Company is unable to raise additional financing include (i) collection of amounts as they come due under customer contracts, (ii) monetization of unutilized capacity under the MSA agreement with Velo3D; (iii) reduction of employee headcount and compensation expenses; and (iv) reduction of outside vendor expenses. Management then evaluated its plans to reduce expenses under the framework provided in ASC Sub-Topic 205-40, and determined that the mitigating effect of its plans sufficiently alleviates the substantial doubt about the Company’s ability to continue as a going concern. Under ASC Sub-Topic 205-40, the mitigating effect of management’s plans is only considered if both (1) it is probable that the plans will be effectively implemented within one year after the date that the consolidated financial statements are issued, and (2) it is probable that the plans, when implemented, will mitigate the relevant conditions or events that raise substantial doubt about the Company’s ability to continue as a going concern within one year after the date that the consolidated financial statements are issued. While the Company believes these actions provide sufficient liquidity for its current operating plans, additional capital may be required in the future to support growth initiatives and achieve profitability, and there can be no assurance that such capital will be available on acceptable terms or at all. The Company’s ability to continue as a going concern is dependent on the Company’s ability to successfully raise capital to fund its business operations and execute on its business plan. To date the Company remains heavily focused on growth and continued development of its proprietary technology, and as a result, it has not generated sufficient revenues to provide cash flows that enable the Company to finance its operations internally. This is reflected by the Company’s incurred net loss of $30.5 million for the year ended December 31, 2025, and accumulated deficit of $438.6 million as of December 31, 2025. Additionally, the Company used net cash of $23.3 million to fund its operating activities for the year ended December 31, 2025, and had cash and cash equivalents of $12.8 million as of December 31, 2025. The accompanying consolidated financial statements have been prepared on a going concern basis of accounting. The accompanying consolidated financial statements do not reflect any adjustments that might result if the Company is unable to continue as a going concern. 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. In addition to the reverse stock split implemented in December 2025, the Company previously effected a 1-for-14 reverse stock split of the Company’s Class A common stock on December 12, 2024, whereby every 14 shares of Class A common stock issued and outstanding on December 12, 2024, 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. The Company’s Class B common 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.

Subsequent Events [Abstract]
Subsequent Events	Note 17. Subsequent Events January 2026 Securities Purchase Agreement On January 5, 2026, the Company entered into a Securities Purchase Agreement for a private placement of securities. The private placement closed on January 6, 2026, resulting in aggregate gross proceeds of approximately $5.0 million, before deducting placement agent commissions and offering expenses. Pursuant to the agreement, the Company issued (i) pre-funded warrants to purchase an aggregate of 925,926 shares of Class A common stock at an exercise price of $0.00001 per share (exercisable immediately and with no expiration date until fully exercised), and (ii) Class A common warrants to purchase an aggregate of 925,926 shares of Class A common stock at an exercise price of $5.40 per share (exercisable following stockholder approval and expiring five years from the stockholder approval date). The securities were sold without registration under the Securities Act of 1933, as amended, in reliance on Section 4(a)(2) and Rule 506(b) thereunder. The Company also issued placement agent warrants to AGP to purchase 46,296 shares of Class A common stock at an exercise price of $5.94 per share, exercisable beginning 180 days after the commencement of sales in the offering. The warrants include beneficial ownership limitations (4.99% of outstanding Class A common stock or voting power) and are subject to standard adjustments for stock splits, dividends, and similar events. The Company is obligated to file a resale registration statement covering the shares issuable upon exercise of the warrants within specified timeframes. Convertible Note Exchange 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. The Company then immediately converted the January 2026 Convertible Note into 50,000 shares of Class A common stock. Partial Conversion of Convertible Note In January and March 2026, the Company converted principal and accrued interest of a portion of the October 2024 Convertible Note into 155,000 shares of Class A common stock. At-The-Market Offering 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. If the Company is eligible to increase the aggregate principal amount available to be sold under the Registration Statement in the future, the Company may file additional supplemental prospectuses to the Registration Statement. During January, February, and March of 2026, the Company issued an aggregate of 2,203,615 shares of Class A common stock under the ATM Sales Agreement for gross proceeds of $13.3 million, before deducting estimated issuance costs of $0.4 million. Up to $23.1 million in aggregate principal amount of an indeterminate amount of shares of the Class A common stock may still be sold under the ATM Sales Agreement. Conversion of Series A preferred stock 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. Shares issued in settlement of accounts payable In March 2026, the Company settled $0.1 million of accounts payable with a vendor through the issuance of 5,723 of Class A common stock.

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.

On May 19, 2025, the Company adopted the first amendment to the 2021 Plan to increase the number of shares of Class A common stock available for issuance under the 2021 Plan by 53,222 shares. All other terms of the 2021 Plan remained the same.

During the year ended December 31, 2025, the shares available for grant under the 2021 Plan increased by 57,871 due to the evergreen provision and increases approved by the Board of Directors and 2 due to forfeitures. As of December 31, 2025, there were 18,980 shares remaining available for grant. Grant activity under the 2021 Plan is described below.

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 December 31, 2025, included in accrued expenses, for employee contributions to the 2021 ESPP, which will be refunded to participants due to the suspension of the plan. As of December 31, 2025, there were 194 shares remaining available for issuance.

2022 Inducement Equity Plan

In February 2022, the Company adopted the 2022 Inducement Equity Plan (the “2022 Plan”), under which 321 shares of Class A common stock were initially reserved for issuance. The 2022 Plan allows for the issuance of

NSOs, RSAs, SARs, RSUs, and stock bonus awards, subject to certain eligibility requirements. The Board of Directors determines the period over which grants become exercisable and grants generally vest over a four‑year period.

On March 22, 2023, the Company adopted the first amendment to the 2022 Plan to increase the number of shares of Class A common stock available for issuance under the 2022 Plan from 321 shares of Class A common stock to 561 shares of Class A common stock. All other terms of the 2022 Plan remained the same.

On May 8, 2023, the Company adopted the second amendment to the 2022 Plan to increase the number of shares of Class A common stock available for issuance under the 2022 Plan from 561 shares of Class A common stock to 641 shares of Class A common stock.

Stockholders' Equity (Deficit)

12 Months Ended

Dec. 31, 2025

Equity [Abstract]

Stockholders' Equity (Deficit)

Note 9. Stockholders' Equity (Deficit)

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 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.

In addition to the reverse stock split implemented in December 2025, the Company previously effected a 1-for-14 reverse stock split of the Company’s Class A common stock on December 12, 2024, whereby every 14 shares of

Class A common stock issued and outstanding on December 12, 2024, 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) — 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.

Shares issued in settlement of accounts payable and customer deposits

During the year ended December 31, 2025, excluding the Baker & McKenzie LLP settlement discussed below, the Company settled $0.4 million of accounts payable and one deposit with several vendors and one customer, respectively, through the issuance of 14,737 shares of Class A common stock. The fair value of the shares issued was determined to be $0.4 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 liabilities settled.

December 2025 Warrant Inducement

On December 9, 2025, the Company entered into a warrant inducement agreement (the “December 2025 Warrant Inducement”) with an investor who was holding the August 2025 Warrants (see discussion of the August 2025 Warrant Inducement below). Pursuant to the December 2025 Warrant Inducement, on December 9, 2025, the investor agreed to exercise for cash all 272,385 of the August 2025 Warrants at an exercise price of $13.74 per share. The investor paid gross proceeds of $3.7 million, before deducting offering fees and other expenses of $0.3 million payable by the Company. Prior to entering into the December 2025 Warrant Inducement, the August 2025 Warrants were immediately exercisable at an exercise price of $19.81 per share. Net proceeds of $3.4 million from the exercise of the August 2025 Warrants was recorded to additional paid-in capital.

The Company determined the fair value of the August 2025 Warrants immediately before and after modification by using a BSM option pricing model and the inducement exercise price of $13.74 per share, respectively, and determined an incremental increase in fair value of approximately $1.5 million. In accordance with ASC Topic 815 guidance on equity classified warrant modifications, the incremental change in fair value of the August 2025

Warrants was accounted for as an additional equity issuance cost for the December 2025 Warrant Inducement, which was recorded to additional paid-in capital. The significant inputs into the BSM option pricing model immediately before modification date are as follows:


Expected term (years)	4.77
Stock price	$	13.57
Volatility	82.50		%
Risk-free rate	3.76		%
Dividend yield	0.00		%

The Company agreed to issue new warrants to purchase up to 408,577 shares of Class A common stock, with an exercise price of $13.74 per share (the “December 2025 Warrants”), in consideration of the investor’s agreement to exercise the August 2025 Warrants. The December 2025 Warrants were exercisable immediately after issuance and expire five years from the date of issuance. The December 2025 Warrants meet the requirements for equity classification. The Company determined the fair value of the December 2025 Warrants at issuance by using a BSM option pricing model, with the following assumptions:


Expected term (years)	5.15
Stock price	$	16.96
Volatility	82.50		%
Risk-free rate	3.73		%
Dividend yield	0.00		%

The Company may not effect the exercise of certain December 2025 Warrants, and the investor will not be entitled to exercise any portion of any such December 2025 Warrant, 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 December 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 December 2025 Warrants.

In connection with the December 2025 Warrant Inducement, the Company also agreed to amend the October 2025 Warrants (see discussion of the October 2025 Warrant Inducement below) to purchase up to an aggregate of 418,466 shares of Class A common stock at an exercise price of $25.53 per share. Prior to amendment, the October 2025 Warrants had a termination date of October 15, 2030. The October 2025 Warrants were amended on December 9, 2025, to have a reduced exercise price of $13.74 per share and will expire five years from the date of stockholder approval.

The Company estimated the fair value of the October 2025 Warrants immediately before and after modification using the BSM option pricing model and determined an incremental increase in fair value of approximately $0.6 million. In accordance with ASC Topic 815 guidance on equity classified warrant modifications, the incremental change in fair value of the October 2025 Warrants was accounted for as an additional equity issuance cost for the December 2025 Warrant Inducement, which was recorded to additional paid-in-capital. The significant inputs into the BSM option pricing model before and after the modification date are as follows:


	Pre-modification			Post-modification
Expected term (years)	5.16			5.16
Stock price	$	13.57		$	13.57
Volatility	82.50		%	82.50		%
Risk-free rate	3.79		%	3.79		%
Dividend yield	0.00		%	0.00		%

October 2025 Warrant Inducement Agreement

On October 14, 2025, the Company entered into a warrant inducement agreement (the “October 2025 Warrant Inducement”) with an investor who was holding the March 2025 Warrants (see discussion of the March 2025

Warrant Inducement below) and the July 2025 Warrants (see discussion of the July 2025 Offering below). Pursuant to the October 2025 Warrant Inducement, on October 14, 2025, the investor agreed to exercise for cash (i) 120,049 of the March 2025 Warrants at an exercise price of $25.53 per share and (ii) 158,929 of the July 2025 Warrants at an exercise price of $25.17 per share. The investor paid gross proceeds of $7.1 million, before deducting offering fees and other expenses of $0.5 million payable by the Company. Prior to entering into the October 2025 Warrant Inducement, the March 2025 Warrants and July 2025 Warrants were immediately exercisable at an exercise price of $35.70 per share and $25.17 per share, respectively. Net proceeds of $6.6 million from the exercise of the March 2025 Warrants and the July 2025 Warrants was recorded to additional paid-in capital.

The Company determined the fair value of the March 2025 Warrants and the July 2025 Warrants immediately before modification by using a BSM option pricing model and immediately after modification by using the inducement exercise prices of $25.53 per share and $25.17 per share, respectively. The Company determined an incremental aggregate increase in fair value of approximately $1.3 million. In accordance with ASC Topic 815 guidance on equity classified warrant modifications, the incremental change in fair value of the March 2025 Warrants and the July 2025 Warrants was accounted for as an additional equity issuance cost for the October 2025 Warrant Inducement, which was recorded to additional paid-in capital. The significant inputs into the BSM option pricing model immediately before the modification date are as follows:


	March 2025 Warrants			July 2025 Warrants
Expected term (years)	4.44			4.71
Stock price	$	30.52		$	30.52
Volatility	85.00		%	85.00		%
Risk-free rate	3.56		%	3.58		%
Dividend yield	0.00		%	0.00		%

The Company agreed to issue new warrants to purchase up to 418,466 shares of Class A common stock, with an exercise price of $25.53 per share (the “October 2025 Warrants”), in consideration of the investor’s agreement to exercise the March 2025 Warrants and July 2025 Warrants. The October 2025 Warrants are exercisable immediately after stockholder approval and will expire five years from the date of stockholder approval. The October 2025 Warrants meet the requirements for equity classification. The Company determined the fair value of the October 2025 Warrants at issuance by using a BSM option pricing model, with the following assumptions:


Expected term (years)	5.31
Stock price	$	30.52
Volatility	85.00		%
Risk-free rate	3.63		%
Dividend yield	0.00		%

The Company may not effect the exercise of certain October 2025 Warrants, and the investor will not be entitled to exercise any portion of any such October 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 October 2025 Warrants (together with its affiliates) to exceed 9.99% 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 October 2025 Warrants.

Baker & McKenzie LLP Settlement

On September 30, 2025, the Company entered into a General Release and Settlement Agreement (the “Settlement Agreement”) with Baker & McKenzie LLP (“B&M”) to settle an obligation of $1.1 million owed by the Company to B&M.

Pursuant to the Settlement Agreement, the Company agreed to (i) pay B&M $0.1 million in cash and (ii) enter into a Securities Purchase Agreement (the “B&M SPA”) to issue to B&M 32,527 Class A common stock and pre-funded warrants to purchase 19,210 shares of Class A common stock (the “B&M Pre-funded Warrants”). The B&M 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 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.

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 is 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 and the Company received an immaterial amount of cash proceeds. The Company recognized $0.4 million in change in fair value of warrant liability in the consolidated statements of operations during the year ended December 31, 2025, related to the ELOC Pre-funded Warrants prior to exercise and, upon exercise, $0.4 million was recorded to additional paid-in capital.

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. No shares were sold under the ELOC, as amended, during the year ended December 31, 2025.

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.

On October 10, 2025, October 20, 2025, and December 12, 2025, the Company filed prospectus supplements to the Registration Statement increasing the aggregate principal amount to $9.2 million, $13.0 million, and $17.4 million, respectively. During the year ended December 31, 2025, the Company issued 757,193 shares of Class A common stock under the ATM Sales Agreement for gross proceeds of $13.6 million, before deducting estimated issuance costs of $0.5 million. The Company subsequently filed additional prospectus supplements to the Registration Statement increasing the aggregate principal amount (see Note 17).

The sales of Class A common stock under the ATM Sales Agreement triggered the downround provisions for each of the previously issued December 2024 Wolverine Warrants, Initial Tranche Warrants, and Second Tranche Warrants on December 2, 2025, December 19, 2025, and December 31, 2025. The Company recorded an aggregate deemed dividend of $0.1 million as a result of these downround adjustments, which were calculated using the BSM option pricing model with the following assumptions:

August 2025 Warrant Inducement

On August 13, 2025, the Company entered into a warrant inducement agreement (the “August 2025 Warrant Inducement”) with an investor who was holding the February 2025 Warrants (see discussion of the February 2025 Offering below) and the Investor Modified Warrants (see discussion of the July 2025 Offering below). Pursuant to the August 2025 Warrant Inducement, on August 13, 2025, the investor agreed to exercise for cash (i) 71,367 of the February 2025 Warrants at an exercise price of $19.81 per share and (ii) 64,826 of the remaining Investor Modified Warrants at an exercise price of $19.81 per share. The investor paid gross proceeds of $2.7 million, before deducting offering fees and other expenses of $0.3 million payable by the Company. Prior to entering into the August 2025 Warrant Inducement, the February 2025 Warrants and Investor were immediately exercisable at an exercise price of $67.83 per share and $25.17 per share, respectively. Net proceeds of $2.4 million from the exercise of the February 2025 Warrants and the Investor Modified Warrants was recorded to additional paid-in capital.

The Company determined the fair value of the February 2025 Warrants and the Investor Modified Warrants immediately before modification by using a BSM option pricing model and immediately after modification by using the inducement exercise price of $19.81 per share. The Company determined there was a decrease in the fair value of the February 2025 Warrants and the Investor Modified Warrants. In accordance with ASC Topic 815 guidance on equity classified warrant modifications, a decrease in fair value is not recognized. The significant inputs into the BSM option pricing model immediately before the modification date are as follows:


	February 2025 Warrants			Investor Modified Warrants
Warrant term (years)	4.49			4.35			-	4.70
Stock price	$	34.09		$	34.09
Volatility	87.50		%	87.50					%
Risk-free rate	3.74		%	3.73		%	-	3.75%
Dividend yield	0.00		%	0.00					%

The Company agreed to issue new warrants to purchase up to 272,385 shares of Class A common stock, with an exercise price of $19.81 per share (the “August 2025 Warrants”), in consideration of the investor’s agreement to exercise the February 2025 Warrants and the Investor Modified Warrants. The August 2025 Warrants were exercisable immediately after issuance and expire five years from the date of issuance. The August 2025 Warrants meet the requirements for equity classification. The Company determined the fair value of the August 2025 Warrants at issuance by using a BSM option pricing model, with the following assumptions:


Warrant term (years)	5.09
Stock price	$	34.09
Volatility	87.50		%
Risk-free rate	3.78		%
Dividend yield	0.00		%

The Company may not effect the exercise of certain August 2025 Warrants, and the investor will not be entitled to exercise any portion of any such August 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 August 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 August 2025 Warrants.

July 2025 Public Offering

On July 01, 2025, the Company consummated a “best efforts” public offering (the “July 2025 Offering”) of an aggregate of (i) 38,096 shares of Class A common stock at a purchase price of $25.17 per share, (ii) pre-funded warrants (the “July 2025 Pre-funded Warrants”) to purchase 120,834 shares of Class A common stock, and (iii) warrants to purchase 158,925 shares of Class A common stock (the “July 2025 Warrants”).

The purchase price of each July 2025 Pre-funded Warrant was equal to the price per share of Class A common stock being sold in the July 2025 Offering minus $0.00001. The July 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 July 2025 Warrants have an exercise price per share of Class A common stock equal to $25.17 per share and will expire five years from the date of issuance. The July 2025 Offering closed on July 01, 2025. Both the July 2025 Pre-funded Warrants and the July 2025 Warrants meet the requirements for equity classification.

The Company received aggregate gross proceeds from the July 2025 Offering of approximately $4.0 million, before deducting issuance costs of $0.6 million. Net proceeds of $3.4 million from the July 2025 Offering was recorded to additional paid-in-capital.

In connection with the July 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 45 days and will 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 3 months after July 1, 2025, subject to certain exceptions.

The Company estimated the fair value of the July 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.

Also in connection with the July 2025 Offering, the Company agreed to amend the remaining Investor Modified Warrants still outstanding (see discussion of the March 2025 Warrant Inducement below) to purchase up to an aggregate of 64,826 shares of Class A common stock. Prior to amendment, the Investor Modified Warrants had an exercise price of $67.83 per share and a termination date of February 11, 2030. Upon amendment, each of the Investor Modified Warrants had a reduced exercise price of $25.17 per share and a termination date of July 1, 2030.

The Company estimated the fair value of the Investor Modified Warrants immediately before and after modification using the BSM option pricing model and determined an incremental increase in fair value of approximately $0.4 million. In accordance with ASC Topic 815 guidance on equity classified warrant modifications, the incremental change in fair value of the Investor Modified Warrants was accounted for as an additional equity issuance cost for

the July 2025 Offering, which was recorded to additional paid-in-capital. The significant inputs into the BSM option pricing model before and after the modification date are as follows:


	Pre-modification						Pre-modification
Warrant term (years)	4.47			-	4.82		4.47			-	4.82
Stock price	$	21.78					$	21.78
Volatility	90.00					%	90.00					%
Risk-free rate	3.76		%	-	3.78%		3.76		%	-	3.78%
Dividend yield	0.00					%	0.00					%

Subsequent to the July 2025 Offering, during the year ended December 31, 2025, the Company issued 120,834 shares of Class A common stock as a result of all of the July 2025 Pre-funded Warrants being exercised and the Company received an immaterial amount of cash proceeds.

Master Services Agreement with Velo3D, Inc.

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 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 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 will not be utilized in the first annual period of the MSA and are thus not recoverable as of December 31, 2025. As a result, $1.7 million of prepaid design and productions services were written off and recognized as an impairment loss in selling, general and administrative expenses in the consolidated statements of operations during the year ended December 31, 2025. In relation to this underutilization of prepaid services, the recognized loss was partially offset by $0.2 million of other income recognized in other expense in the consolidated statements of operations during the year ended December 31, 2025, for a recognized increase in the fair value of the Credit Provision Derivative of $0.2 million as of December 31, 2025. The Credit Provision Derivative asset is recorded in prepaids and other current assets in the consolidated balance sheets.

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.

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.

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.

On March 4, 2024, the Company entered into a Securities Purchase Agreement, with an investor, pursuant to which the Company issued and sold to the investor in a registered direct offering (the “March 2024 Offering”), (i) an aggregate of 5,283 shares of the Company’s Class A common stock at a purchase price of $216.16 per share, (ii) pre‑funded warrants (the “March 2024 Pre-funded Warrants”) to purchase 13,223 shares of the Company’s Class A common stock, and (iii) warrants to purchase 18,505 shares of Class A common stock (the “March 2024 Warrants”).

The purchase price of each March 2024 Pre-funded Warrant was equal to the price per share of Class A common stock being sold in the March 2024 Offering minus $0.00001. The March 2024 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 March 2024 Warrants have an exercise price per share of Class A common stock equal to $184.93 per share and will expire five years from the date of issuance. The March 2024 Offering closed on March 7, 2024. Both the March 2024 Pre-funded Warrants and the March 2024 Warrants meet the requirements for equity classification.

The Company received aggregate gross proceeds from the March 2024 Offering of approximately $4.0 million, before deducting estimated issuance costs of $0.5 million. Net proceeds of $3.5 million from the March 2024 Offering were recorded to additional paid-in-capital.

The Company estimated the fair value of the March 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 March Warrants using the BSM option pricing model. The significant inputs into the BSM option pricing model at the initial recognition date are as follows:


Warrant term (years)	5.00

Volatility	97.50	%
Risk-free rate	4.07	%
Dividend yield	—	%

In connection with the March 2024 Offering, the Company agreed to amend the January 2024 Warrants (see discussion of the January 2024 Offering below) to purchase up to an aggregate of 14,754 shares of Class A common stock at an exercise price of $239.90 per share. Prior to amendment, the January 2024 Warrants had a termination date of January 17, 2029. Upon shareholder approval of the amendment, the January 2024 Warrants had a reduced exercise price of $184.93 per share and a termination date of June 28, 2029.

The Company estimated the fair value of the January 2024 Warrants immediately before and after modification using the BSM option pricing model and determined an incremental increase in fair value of approximately $0.1 million. In accordance with ASC Topic 815 guidance on equity classified warrant modifications, the incremental change in fair value of the January 2024 Warrants was accounted for as an additional equity issuance cost for the March 2024 Offering, which was recorded to additional paid-in-capital. The significant inputs into the BSM option pricing model before and after the modification date are as follows:


	Pre-modification		Post-modification
Warrant term (years)	4.87		5.00

Volatility	95.00	%	95.00	%
Risk-free rate	4.22	%	4.21	%
Dividend yield	0.00	%	0.00	%

Subsequent to the March 2024 Offering, during the year ended December 31, 2024, the Company issued 13,223 shares of Class A common stock as a result of all of the March 2024 Pre-funded Warrants being exercised and the Company received an immaterial amount of cash proceeds.

January 2024 Securities Purchase Agreement

On January 12, 2024, the Company entered into a Securities Purchase Agreement, with an investor, pursuant to which the Company issued and sold to the investor in a registered direct offering (the “January 2024 Offering”), (i) an aggregate of 3,602 shares of the Company’s Class A common stock at a purchase price of $271.14 per share, (ii) pre-funded warrants (the “January 2024 Pre-funded Warrants”) to purchase 11,153 shares of the Company’s Class A common stock, and (iii) warrants to purchase 14,754 shares of Class A common stock (the “January 2024 Warrants”).

The purchase price of each January 2024 Pre-funded Warrant was equal to the price per share of Class A common stock being sold in the January 2024 Offering minus $0.00001. The January 2024 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 January 2024 Warrants have an exercise price per share of Class A common stock equal to $239.90 per share and will expire five years from the date of issuance. The January 2024 Offering closed on January 17, 2024. Both the January 2024 Pre-funded Warrants and the January 2024 Warrants meet the requirements for equity classification.

The Company received aggregate gross proceeds from the January 2024 Offering of approximately $4.0 million, before deducting estimated issuance costs of $0.4 million. Net proceeds of $3.6 million from the January 2024 Offering were recorded to additional paid-in-capital.

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

of the January 2024 Warrants using the BSM option pricing model. The significant inputs into the BSM option pricing model at the initial recognition date are as follows:


Expected term (years)	5.00

Volatility	97.50	%
Risk-free rate	4.02	%
Dividend yield	—	%

In connection with the January 2024 Offering, the Company agreed to amend each of the warrants issued in November 2023 to purchase up to an aggregate of 23,244 shares of Class A common stock at an exercise price of $964.61 per share (the “November 2023 Modified Warrants”). Prior to amendment, the November 2023 Modified Warrants had a termination date of November 9, 2028. The November 2023 Modified Warrants were amended on May 9, 2024, to have a reduced exercise price of $136.02 per share and a termination date of May 9, 2029.

The Company estimated the fair value of the November 2023 Modified Warrants immediately before and after modification using the BSM option pricing model and determined an incremental increase in fair value of approximately $1.2 million. In accordance with ASC Topic 815 guidance on equity classified warrant modifications, the incremental change in fair value of the November 2023 Modified Warrants was accounted for as an additional equity issuance cost for the January 2024 Offering, which was recorded to additional paid-in-capital. The significant inputs into the BSM option pricing model before and after the modification date are as follows:


	Pre-modification		Post-modification
Expected term (years)	4.83		5.00

Volatility	97.50	%	97.50	%
Risk-free rate	3.85	%	3.84	%
Dividend yield	0.00	%	0.00	%

Subsequent to the January 2024 Offering, during the year ended December 31, 2024, the Company issued 11,153 shares of Class A common stock as a result of all of the January 2024 Pre-funded Warrants being exercised and the Company received an immaterial amount of cash proceeds.

Public and Private Warrants

As of December 31, 2025, the Company had Public and Private Warrants outstanding to purchase 691 shares and 903 shares of Class A common stock, respectively, related to the Business Combination. The warrants entitle the registered holder to purchase stock at a price of $143,693 per share, subject to adjustment, at any time commencing on August 12, 2021. The Public and Private Warrants expire on the fifth anniversary of the Business Combination, or earlier upon redemption or liquidation.

The Private Warrants assumed in connection with the Business Combination are accounted for as a derivative liability. The Public Warrants and the legacy outstanding Private Warrants were recorded as equity within the consolidated statements of stockholders' equity (deficit).

Contingent Sponsor Earnout Shares

As a result of the Business Combination, the Company modified the terms of 116 shares of Class A common stock held by SRAC’s sponsor (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 fifth anniversary of the Business Combination. Certain events which change the number of outstanding shares of Class A common stock, such as a split, combination, or recapitalization, among other potential events, will equitably adjust the target vesting prices above. 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).

Legal Proceedings

Securities Class Actions

On July 15, 2021, a purported stockholder of SRAC filed a putative class action complaint against SRAC, SRC-NI Holdings, LLC (“Sponsor”), Brian Kabot (SRAC CEO), James Norris (SRAC CFO), Momentus, and the Company’s co-founder and former CEO, Mikhail Kokorich, in the United States District Court for the Central District of California, in a case captioned Jensen v. Stable Road Acquisition Corp., et al., No. 2:21-cv-05744 (the “Jensen class action”). The complaint alleges that the defendants omitted certain material information in their public statements and disclosures regarding the Business Combination, in violation of the securities laws, and seeks damages on behalf of a putative class of stockholders who purchased SRAC stock between October 7, 2020, and July 13, 2021. Subsequent complaints captioned Hall v. Stable Road Acquisition Corp., et al., No. 2:21-cv-05943 and Depoy v. Stable Road Acquisition Corp., et al., No. 2:21-cv-06287 were consolidated in the first filed matter (collectively, referred to as the “Securities Class Actions”). An amended complaint was filed on November 12, 2021. The Company disputes the allegations in the Securities Class Actions.

On February 10, 2023, the lead plaintiff in the Securities Class Actions and the Company reached an agreement in principle to settle the Securities Class Actions. Under the terms of the agreement in principle, the lead plaintiff, on behalf of a class of all persons that purchased or otherwise acquired Company stock between October 7, 2020 and July 13, 2021, inclusive, would release the Company from all claims asserted or that could have been asserted in the Securities Class Actions and dismiss such claims with prejudice, in exchange for payment of $8.5 million by the Company (at least $4.0 million of which was funded by insurance proceeds).

On April 10, 2023, the parties filed a Notice of Settlement with the Court, and on August 18, 2023, the parties executed a Settlement Agreement. On August 30, 2023 the lead plaintiff filed a Motion for Preliminary Approval of Class Action Settlement, and the Court entered an Order Preliminarily Approving Settlement and Providing for Notice on September 21, 2023. Pursuant to that Order, on October 5, 2023, the Company paid $1.0 million into the settlement escrow account. On November 16, 2023, following the Court’s order granting lead plaintiff’s motion to enforce the settlement agreement and despite the Company’s attempts to negotiate an extension of time to satisfy its payment obligations, the Company paid an additional $3.5 million into the settlement escrow account. Insurance carriers made additional payments totaling $4.0 million into the settlement escrow account.

On April 23, 2024, the Court entered an order and judgment finally approving the settlement of the Securities Class Actions. A group of plaintiffs asserting the Delaware Class Actions (see below) objected to the scope of the release in the settlement, and the Court overruled the objection. Those objectors may or may not appeal the Court’s decision to overrule their objections and approve the settlement. The Company does not know the timing of when such an appeal, if filed, would be heard. If the objectors do not appeal the approval of the settlement, or if their appeal is ultimately rejected by the Court of Appeals, then the settlement will resolve all claims in the Securities Class Actions against the Company (except as to any shareholders that may elect to opt-out of the class). The Company and the other defendants have denied and continue to deny each and all of the claims alleged in the Securities Class Actions, and the proposed settlement contains no admission of liability, wrongdoing or responsibility by any of the defendants. In the event that a court, on appeal or otherwise, overturns the approval of the settlement, the Company will continue to vigorously defend against the claims asserted in the Securities Class Actions.

As a result of the agreement to settle the Securities Class Action, the Company recorded a litigation settlement contingency of $8.5 million. The Company additionally recorded an insurance receivable of $4.0 million for the insurance proceeds expected from its insurers related to the settlement. The net amount of $4.5 million was recognized in litigation settlement, net during the year ended December 31, 2022. As of December 31, 2024, the contingent liability in relation to Securities Class Action had been paid in full.

Shareholder Derivative Litigation

On June 20, 2022, a shareholder derivative action was filed by Brian Lindsey, on behalf of the Company, in the U.S. District Court for the Central District of California, Case No. 2:22-cv-04212, against the Company (as a nominal defendant), SRAC, Brian Kabot, Juan Manuel Quiroga, James Norris, James Hofmockel, Mikhail Kokorich, Dawn Harms, Fred Kennedy, Chris Hadfield, Mitchel B. Kugler, Victorino Mercado, Kimberly A. Reed, Linda J. Reiners, and John C. Rood. This derivative action alleges the same core allegations as stated in the Securities Class Actions litigation. The defendants dispute the allegations as stated in this derivative action. On September 27, 2022, the plaintiff filed his Notice of Voluntary Dismissal without Prejudice seeking to dismiss the case. Because the plaintiff’s dismissal of this derivative action was voluntary and without prejudice, this plaintiff and/or other shareholders may seek to re‑file the claims asserted in this matter at a later date. As noted below, Brian Lindsey re‑filed a shareholder derivative action in Delaware Chancery Court on June 30, 2023.

On January 25, 2023, a shareholder derivative action was filed by Melissa Hanna, on behalf of the Company, in the U.S. District Court for the Northern District of California, Case No. 5:23-cv-00374, against the Company (as a nominal defendant), SRAC, Brian Kabot, Juan Manuel Quiroga, James Norris, James Hofmockel, Mikhail Kokorich, Dawn Harms, Fred Kennedy, Chris Hadfield, Mitchel B. Kugler, Victorino Mercado, Kimberly A. Reed, Linda J. Reiners, and John C. Rood (the “Derivative Action II”). The Derivative Action II alleges the same core allegations as stated in the Securities Class Actions, and also claims that the Company ignored and/or refused a prior demand made by Ms. Hanna on the Company’s Board of Directors. The Company intends to vigorously defend the litigation.

On April 25, 2023, a shareholder derivative action was filed by Justin Rivlin, purportedly on behalf of the Company, in the U.S. District Court for the District of California, Case No. 2:23-cv-03120, against the Company (as a nominal defendant), Brian Kabot, James Norris, Marc Lehmann, James Hofmockel, and Ann Kono. The Rivlin derivative action alleges the same core allegations as stated in the Securities Class Actions. The Company has filed a motion to dismiss the complaint on the grounds that the claims are time-barred and that the plaintiff was not excused from making a demand on the Company before filing the lawsuit. The Company intends to vigorously defend the litigation. On August 4, 2023, the plaintiff in the Rivlin action responded to the Company’s motion to dismiss by filing an amended complaint adding new claims and new defendants, including existing Board members Chris Hadfield, Mitchel B. Kugler, Kimberly A. Reed, Linda J. Reiners, and John C. Rood.

On June 30, 2023, a shareholder derivative action was filed by Brian Lindsey, purportedly on behalf of the Company in the Court of Chancery for the State of Delaware (Case No. 2023-0674), against the Company (as a nominal defendant), Juan Manuel Quiroga, James Norris, James Hofmockel, Stable Road Acquisition Corp., SRC-NI Holdings, LLC, Mikhail Kokorich, Brian Kabot, Dawn Harms, Fred Kennedy, Chris Hadfield, Mitchel B. Kugler, Victorino Mercado, Kimberly A. Reed, Linda J. Reiners, and John C. Rood. The Lindsey derivative action alleges the same core allegations as stated in the Securities Class Actions. The Company intends to vigorously defend the litigation.

On August 26, 2024, an unopposed motion for the preliminary approval of settlement was filed after the Company reached an agreement in principle for a proposed settlement of certain shareholder derivative litigation. The proposed settlement, as set forth more fully in the Stipulation and Agreement of Settlement filed with the court, requires the Company to adopt certain corporate governance reforms. The reforms must be maintained for a minimum period of four years.

On September 16, 2024, the U.S. District Court for the Northern District of California issued an order primarily approving the settlement and providing for notice of the settlement to stockholders of the Company in the matters captioned Hanna v. Kabot, et al., Case No. 5:23-cv-00374 (N.D. Cal.); Rivlin v. Kabot, et al., Case No. 2:23‑cv-03120 (C.D. Cal.);  Lindsey v. Quiroga, et al., Case No. 20230674 (Del. Ch.); and the litigation demand made by Momentus stockholder, Kamal Qureshi (collectively, the “Derivative Matters”). The proposed settlement calls for the Company to adopt certain corporate governance reforms and pay lead plaintiffs’ attorney’s fees, litigation expenses, and lead plaintiff service awards.

The order set a final approval hearing for November 21, 2024, and the U.S. District Court for the Northern District of California approved the settlement agreement, including the dismissal with prejudice of all claims against the defendants, via Order dated January 10, 2025. The matter was fully covered under the Company’s insurance policy, and all associated legal fees and settlement costs were paid directly by the insurer. As a result, the Company did not incur any expenses related to legal fees or settlement costs in connection with this matter.

SAFE Note Litigation

On July 20, 2022, The Larian Living Trust (“TLLT”) filed an action against the Company in New Castle County Superior Court, Delaware, in the Complex Commercial Litigation Division, Case No. N22C-07-133 EMD CCLD. TLLT pleads claims for fraudulent inducement and breach of contract arising from two investment contracts pursuant to which TLLT alleges it invested $4.0 million in the Company. TLLT alleges that a “liquidity event” occurred when the Company closed the Business Combination, such that it was entitled to the greater of its $4.0 million investment or its “Conversion Amount” of the Company’s shares, which was a total of 59 shares of the Company’s stock. TLLT further alleges that the Company refused to provide it the conversion amount of shares until April 2022, at which point the value of its shares had dropped significantly from their peak value in August of 2021, in excess of $7.6 million. TLLT seeks damages in excess of $7.6 million, in addition to interests and its attorney’s fees and costs. On March 16, 2023, the Company’s motion to dismiss TLLT’s claims was denied and the parties will move forward with discovery. On July 13, 2023, the Company filed a motion for partial summary judgment. The hearing on the Company’s motion for partial summary judgment was set for November 8, 2023, TLLT filed an Answering Brief on September 15, 2023, and the Company filed a Reply Brief on October 16, 2023. On January 31, 2024, the Superior Court denied the Company’s motion for partial summary judgment. The Company disputes the allegations in the complaint and intends to vigorously defend the litigation. The Company and TLLT have held settlement discussions, but an agreement in principle has not been finalized. On April 30, 2025, the Court entered an order stating that the matter would be dismissed for want of prosecution if no proceedings are undertaken within 30 days of that date. No such proceedings have been instituted by the plaintiff after the filing of that order.

Founder Litigation

On June 8, 2021, former co-founders and shareholders of the Company, Mikhail Kokorich and Lev Khasis, signed the NSA alongside stock repurchase agreements, whereby they agreed to divest their interests in the Company in exchange for a cash payment and other considerations. As part of the NSA and stock repurchase agreements, Messrs. Kokorich and Khasis agreed to a broad waiver and release of all claims (broadly defined) against the Company. The Company has maintained that this release is effective as to various advancement and indemnification claims either individual may have against the Company.

Both Messrs. Kokorich and Khasis have, through counsel, disagreed with the Company’s position. For example, Mr. Kokorich is named as a defendant in the securities class action pending against the Company and other defendants, although he has not been served nor appeared in those matters. In addition, Mr. Kokorich is the sole defendant in a civil litigation action filed against him by the SEC in the U.S. District Court for the District of Columbia, Case No. 1:21-cv-01869. On November 25, 2024, the U.S. District Court for the District of Columbia entered a final consent judgment in the SEC’s civil action against Mr. Kokorich (Case No. 1:21-cv-01869), resolving all claims in that proceeding. Mr. Kokorich has demanded indemnification and advancement from the Company for his fees and costs incurred in these actions, which claims are disputed by the Company.

The Company continues to maintain that Mr. Kokorich’s release in the NSA and stock repurchase agreements is effective as to his claims for advancement and indemnification in these litigation matters. On August 16, 2022, Mr. Kokorich filed a verified complaint against the Company in the Delaware Court of Chancery (Case No. 2022‑0722) seeking indemnification and advancement from the Company. Following the Company filing a motion to dismiss this action, on November 14, 2022, Mr. Kokorich filed an amended complaint. Additional motions to dismiss and replies were filed and considered at a hearing on February 2, 2023. The Delaware Court of Chancery granted the Company’s motion to dismiss the Kokorich indemnification claim action on May 15, 2023. On June 13, 2023, Mr. Kokorich filed a notice of appeal. On July 28, 2023, Mr. Kokorich filed Appellant’s Brief. The Company filed Appellee’s Answering Brief on August 28, 2023, and Mr. Kokorich filed a Reply Brief on September 15, 2023. The oral argument on Mr. Kokorich’s appeal was scheduled for November 15, 2023. On November 30, 2023, the Delaware Supreme Court affirmed the judgment of the Delaware Court of Chancery.

On March 24, 2023, Mr. Khasis filed a verified complaint against the Company in the Delaware Court of Chancery (Case No. 2023-0361) seeking indemnification and advancement of expenses from the Company. On April 17, 2023, the Company filed a motion to dismiss. On May 16, 2023. Mr. Khasis filed an amended complaint. On May 23, 2023, Momentus filed a motion to dismiss the amended complaint. Separately, Mr. Khasis has requested an expedited trial in his claim for advancement of fees. On June 23, 2023, the Court of Chancery ordered that

Mr. Khasis indemnification litigation will not be stayed pending the appeal of the Kokorich claim. Moreover, the Court of Chancery further ordered the parties to prepare a scheduling order to the Court which includes all relevant deadlines to argue the Company’s motion to dismiss and Mr. Khasis’ expedited motion for advancement concurrently.

In response to the Court’s request for a status update, the Plaintiff moved to voluntarily dismiss its complaint without prejudice, which Momentus did not oppose. On November 26, 2024, the Court granted plaintiff’s motion.

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 Securities and Exchange Commission. Legal counsel to Khasis indicated that total expenses for which Khasis seeks indemnification is approximately $1.2 million plus legal expenses in connection with this suit. The Company believes it is probable that it can settle this claim for an amount of approximately $0.4 million. The Company is attempting to resolve these claims, but there can be no assurances a resolution will be achieved.

Delaware Class Actions

On November 10, 2022, purported stockholders filed a putative class action complaint against Brian Kabot, James Hofmockel, Ann Kono, Marc Lehmann, James Norris, Juan Manuel Quiroga, SRC-NI Holdings, LLC, Edward K. Freedman, Mikhail Kokorich, Dawn Harms, Fred Kennedy, and John C. Rood in the Court of Chancery of the State of Delaware, in a case captioned Shirley, et al. v. Kabot et al., 2022-1023-PAF (the “Shirley Action”). The complaint alleges that the defendants made certain material misrepresentations, and omitted certain material information, in their public statements and disclosures regarding the Proposed Transaction, in violation of the securities laws, and seeks damages on behalf of a putative class of stockholders who purchased SRAC stock on or before August 9, 2021. On December 23, 2024, by stipulation and order of dismissal, Mr. Rood was dismissed from the complaint without prejudice.

On March 16, 2023, purported stockholders of the Company filed a putative class action complaint against certain current and former directors and officers of the Company in the Delaware Court of Chancery, in a case captioned Lora v. Kabot, et al., Case No. 2023-0322 (the “Lora Action”). Like the Shirley complaint, the complaint alleges that the defendants made certain material misrepresentations, and omitted certain material information, in their public statements and disclosures regarding the Business Combination in violation of the securities laws, and seeks damages on behalf of a putative class of stockholders who purchased SRAC stock on or before August 9, 2021.

On March 17, 2023, purported stockholders of the Company filed a putative class action complaint against certain current and former directors and officers of the Company in the Delaware Court of Chancery, in a case captioned Burk v. Kabot, et al., Case No. 2023-0334 (the “Burk Action”). Like the Lora and Shirley complaints, the Burk complaint alleges that the defendants made certain material misrepresentations, and omitted certain material information, in their public statements and disclosures regarding the Business Combination in violation of the securities laws, and seeks damages on behalf of a putative class of stockholders who purchased SRAC stock on or before August 9, 2021.

On May 26, 2023, plaintiffs filed a stipulation and proposed order for consolidation and appointment of co-lead plaintiffs and co-lead plaintiffs’ counsel designating the complaint filed in the Lora Action as the operative complaint. On June 30, 2023, the defendants each filed a motion to dismiss the complaint. On October 26, 2023, plaintiffs filed their answering briefs in opposition to the motions to dismiss, and the defendants’ reply briefs were due to be filed on or before December 14, 2023, and a hearing on the motions to dismiss was held for February 1, 2024.

On May 29, 2024, the court issued its orders on the motions to dismiss: (1) granting the motions to dismiss with respect to defendants Fred Kennedy and Dawn Harms and dismissing the claims against them with prejudice, and (2) with respect to the SRAC Defendants, granting the motion to dismiss with prejudice. However, the court noted that defendants Brian Kabot, James Hofmockel, and James Norris did not move to dismiss the portion of Count II relating to alleged misrepresentations concerning the value of SRAC shares issued in the merger and defendant Brian Kabot did not move to dismiss the portion of Count III relating to the same. As such, the claims as to the SRAC Defendants were dismissed with prejudice, except for these remaining claims.

The Shirley Action, the Lora Action, and the Burk Action have been consolidated under the caption, In re Momentus Inc. Stockholders Litigation, C.A. No. 2022-1023-PAF (Del Ch. Nov. 10, 2022). These putative class actions do not name the Company as a defendant. Regardless, the SRAC directors and officers, together with current and former directors and officers of the Company, have demanded indemnification and advancement from the Company, under the terms of the merger agreement and the exhibits thereto, the Delaware corporate code, the Company’s Bylaws, and their individual indemnification agreements. The Company may be liable for the fees and costs incurred by the defendants and has an obligation to advance such fees during the pendency of the litigation. The Company understands that the defendants dispute the allegations in the complaint and intend to vigorously defend against any such litigation.

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. 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.

Indemnification Claims

On July 31, 2024, certain former employees of the Company obtained a legal judgment in the amount of $0.5 million inclusive of interest and expenses related to claims for the advancement and reimbursement of certain legal expenses of the former employees. The Company paid the former employees $0.5 million in September 2024.

Lease Restoration

The Company entered a lease for office space at 1762 Automation Parkway, San Jose, California 95131 in December 2025. The Company has leased a facility at 3901 North First Street, San Jose, California 95134 (“3901”) that expires on March 31, 2026. The Company intends to vacate 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.

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 December 31, 2025, the Company has recorded accruals for certain probable loss contingencies and an ARO. These include $0.4 million accrued for the Khasis claim, $0.3 million for the ANV claim, and a $0.5 million ARO recognized for the 3901 sublease. The $0.7 million of probable loss contingencies are recorded in litigation settlement contingency in the consolidated balance sheets, and the $0.5 million ARO is recorded in other current liabilities in the consolidated balance sheets. The Company believes these accruals are adequate based on information currently available.

The state income taxes, net of federal benefit, primarily relate to California, Virginia, and New York, which together comprise more than 50% of the amount.

Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Significant components of the Company’s deferred tax assets and liabilities are as follows:


(in thousands)	December 31, 2025		December 31, 2024
Deferred tax assets:
Net operating loss carryforwards	$	60,915	$	47,769

Management regularly assesses the ability to realize deferred tax assets recorded based upon the weight of available evidence, including such factors as recent earnings history and expected future taxable income on a jurisdiction by jurisdiction basis. In the event that the Company changes its determination as to the amount of realizable deferred tax assets, 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’s management believes that, based on a number of factors, it is more likely than not, that all or some portion of the deferred tax assets will not be realized; and accordingly, for the year ended December 31, 2025 the Company has provided a valuation allowance against the Company’s U.S. net deferred tax assets. The net change in the valuation allowance for the year ended December 31, 2025 was an increase of $6.5 million.

As of December 31, 2025, the Company had net operating loss carryforwards for federal and state income tax purposes of $259.6 million and $103.4 million, respectively, which will begin to expire in 2037, with $246.9 million of the Company’s federal net operating loss carryforward lasting indefinitely. As of December 31, 2024, the Company had federal and state net operating loss carryforwards of $202.6 million and $79.6 million, respectively. As of December 31, 2025, the Company had federal and California research and development credit carryforwards of $4.0 million and $3.1 million, respectively. As of December 31, 2024, the Company had federal and California research and development credit carryforwards of $4.0 million and $3.1 million, respectively. The federal research and development credit carryforwards will begin to expire in 2039, while the California research and development credits carry forward have an indefinite life.

The Internal Revenue Code of 1986, as amended, imposes restrictions on the utilization of net operating losses in the event of an “ownership change” of a corporation. Accordingly, a company’s ability to use net operating losses may be limited as prescribed under Internal Revenue Code Section 382 (“IRC Section 382”). Events which may cause limitations in the amount of the net operating losses that the Company may use in any one year include, but are not limited to, a cumulative ownership change of more than 50% over a three-year period. Utilization of the federal and state net operating losses may be subject to substantial annual limitation due to the ownership change limitations provided by the IRC Section 382 and similar state provisions.

As of December 31, 2025 and 2024, the total amount of gross unrecognized tax benefits was $1.8 million and $1.8 million, respectively, including no interest and penalties. As of December 31, 2025, none of the total unrecognized tax benefits, if recognized, would have an impact on the Company’s effective tax rate. The Company’s policy is to

recognize interest and penalties accrued on any unrecognized tax benefits as a component of income tax expense. There were no changes in uncertain tax positions during the years ended December 31, 2025 and 2024.

The Company files income tax returns in the U.S. federal and various state jurisdictions with varying statutes of limitations. The Company is generally no longer subject to tax examinations for years prior to 2021 for federal purposes and 2020 for state purposes, except in certain limited circumstances.

Before Vigoride 3 launch, the Company was in start-up phase and had no revenue recognized as of May 31, 2022. Under Section 195(b), all the expenses other than R&D, taxes and interest income/expense must be capitalized and amortized from the date the Company starts active trade or business. The Company began active trade or business as of June 1, 2022 and amortized Section 195(b) costs for the remainder of the year. As of December 31, 2025 and 2024, the Company has Section 195(b) gross deferred tax assets of $64.2 million and $69.8 million, respectively.

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.

Debt Disclosure [Abstract]

Loan Payable

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 and December 31, 2025, 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 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 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 December 31, 2025, 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 December 31, 2025, the September 2025 Convertible Note has a carrying amount of $0.4 million, consisting of principal of $1.6 million and net unamortized discount of $1.2 million. The September 2025 Convertible Note has future scheduled maturities of $1.6 million in 2026. For the year ended December 31, 2025, interest recognized on the September 2025 Convertible Note totaled $0.5 million. This amount consists of cash interest expense of $0.04 million and non-cash amortization of debt discount of $0.4 million.

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.

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 year ended December 31, 2025.

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 26,693 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:


Expected term (years)	5.00
Stock price	$	29.99
Volatility	90.00		%
Risk-free rate	4.04		%
Dividend yield	0.00		%

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 26,693 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 26,693 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 the consolidated statements of operations 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 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 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 as of December 31, 2025.

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.

December 2024 Loan

On December 13, 2024, the Company and J.J. Astor & Co. entered into a loan agreement (the “December 2024 Loan”) pursuant to which the Company borrowed $2.0 million and paid debt issuance costs of $0.3 million. The December 2024 Loan had a maturity date of September 19, 2025, and was payable in 40 weekly installments of $68 thousand. The December 2024 Loan could be prepaid at any time on or before January 13, 2025, for $2.4 million and at any time thereafter through the maturity date for $2.7 million.

Amounts borrowed under the December 2024 Loan are secured by a lien on substantially all of the assets of the Company. Upon event of default, amounts owing under the December 2024 Loan are convertible into shares of Class A common stock at a conversion price of $105.67 per share prior to May 5, 2025, and thereafter the conversion price will be reduced 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.

In addition, in connection with the December 2024 Loan, the Company agreed to issue J.J. Astor & Co. warrants to purchase up to 1,601 shares of Class A common stock with an exercise price of $105.67 per share (the “December 2024 Wolverine Warrants”). The December 2024 Wolverine Warrants had a relative value of $0.1 million which was accounted for as an additional debt issuance cost for the December 2024 Loan. The warrants are fully vested, and expire five years from the date of issuance. The Company determined the fair value of the December 2024 Wolverine Warrants by using a BSM option pricing model, with the following assumptions:


Expected term (years)	5.01
Stock price	$	105.67
Volatility	100.00		%
Risk-free rate	4.25		%
Dividend yield	0.00		%

On December 18, 2024, the Company prepaid $2.4 million in order to extinguish the December 2024 Loan. The Company recognized a $0.8 million loss on extinguishment in the consolidated statements of operations related to the December 2024 Loan.

In connection with the December 2024 Loan, the Company agreed to issue J.J. Astor & Co. a second warrant that is exercisable and issuable upon certain customary events of default to purchase up to 16,007 shares of Class A common stock with an exercise price per share equal to the closing price of the Class A common stock as traded in the applicable trading market on the date of the event of default, subject to adjustment (the “Default Warrants”). The Default Warrants were an embedded derivative that required bifurcation and recognition as a derivative liability (the “Default Warrant Derivative”). The Default Warrant 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 immediately prior to extinguishment of the December 2024 Loan on December 18, 2024, the Default Warrant Derivative was valued at zero.

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 bears 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.

Amounts borrowed under the July 2024 Convertible Note are 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, may 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 automatically convert into Class A common stock at the conversion price.

The July 2024 Convertible Note requires SIV’s consent to take certain actions, such as increasing compensation, purchasing assets, extending financing, making capital expenditures, repaying debts outside the ordinary course of business or investing in any entity or enterprise.

The July 2024 Convertible Note can be prepaid in full at any time, subject to a prepayment penalty fee of 10%. The July 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 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 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, 2024, 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) up to an additional $1.0 million in principal amount which could be borrowed from December 2, 2024 through February 14, 2025. Borrowings under the October 2024 Convertible Note bear interest at 15% per annum. The October 2024 Convertible Note has a maturity date of October 24, 2025, at which time all principal and accrued interest is due. The Company paid debt issuance costs of $0.1 million in relation to borrowing $2.0 million under the first tranche of the October 2024 Convertible Note.

As a third-party debt issuance cost related to the October 2024 Convertible Note, the Company agreed to issue investor warrants to purchase up to 20,009 shares of Class A common stock with an exercise price of $143.69 per share (the “Investor Warrants”). The Investor Warrants had a fair value of $2.0 million which was as accounted for as debt issuance costs allocated between two tranches of the October 2024 Convertible Note; $1.3 million was allocated to the first tranche and $0.7 million was allocated to the second tranche. The investor may not exercise the Investor Warrants prior to April 24, 2025, and the Investor Warrants will expire April 24, 2030. The Company determined the fair value of the warrants by using a BSM option pricing model, with the following assumptions:


Expected term (years)	5.50
Stock price	$	132.27
Volatility	97.50		%
Risk-free rate	4.05		%
Dividend yield	0.00		%

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.

In addition, in connection with the first tranche of the October 2024 Convertible Note, the Company agreed to issue SIV warrants to purchase up to 15,124 shares of Class A common stock with an exercise price of $132.27 per share (the “October 2024 SIV Warrants”). The October 2024 SIV Warrants had a relative value of $0.8 million which was as accounted for as an additional debt issuance cost for the October 2024 Convertible Note. SIV may not exercise the October 2024 SIV Warrants prior to April 24, 2025, and the October 2024 SIV Warrants will expire April 24, 2030. The Company determined the fair value of the warrants by using a BSM option pricing model, with the following assumptions:


Expected term (years)	5.44
Stock price	$	157.44
Volatility	97.50		%
Risk-free rate	4.33		%
Dividend yield	0.00		%

Neither the October 2024 Convertible Note nor the October 2024 SIV Warrants can be converted or exercised if it would cause the aggregate number of shares of Class A common stock beneficially owned by SIV to exceed 9.99% of the number of shares of Class A common stock outstanding immediately after giving effect to the conversion or

exercise, as applicable. Conversion of the October 2024 Convertible Note and exercise of the October 2024 SIV Warrants are also subject to compliance with applicable Nasdaq rules, and if shareholder approval is required the Company will use commercially reasonable efforts to obtain such approval.

The October 2024 Convertible Note requires SIV’s consent to take certain actions, such as 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 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, December 31, 2024, and December 31, 2025, the October 2024 Default Interest Derivative was valued at zero.

In November 2024, the Company amended the SIV Convertible Notes (the “November 2024 Amendment”). The November 2024 Amendment, among other things, accelerated the borrowing date for the second tranche of the October 2024 Convertible Note, for which the Company immediately borrowed the $1.0 million available under the second tranche, and provided that amounts owed under both the July 2024 Convertible Note and the October 2024 Convertible Note may be converted to Class A common stock at any time. The November 2024 Amendment was accounted for as an extinguishment of both of the SIV Convertible Notes. The Company recognized a $3.2 million loss on extinguishment in the consolidated statements of operations related to the November 2024 Amendment, resulting from the difference between the carrying value and reacquisition price of the July 2024 Convertible Note and the first tranche of the October 2024 Convertible Note. The Company recognized an aggregate debt premium of $1.2 million related to the July 2024 Convertible Note and the first tranche of the October 2024 Convertible Note as a result. Furthermore, the Company recognized an additional $0.3 million loss on extinguishment in the consolidated statements of operations for a debt premium resulting from the difference between the proceeds received and fair value of the second tranche of the October 2024 Convertible Note.

In addition, in connection with the November 2024 Amendment, the Company issued to SIV warrants to purchase up to 10,828 shares of Class A common stock with an exercise price of $132.27 per share (the “December 2024 SIV Warrants”). The December 2024 SIV Warrants had a relative value of $0.5 million which was as accounted for as an additional debt issuance cost for the second tranche of the October 2024 Convertible Note. SIV was prohibited to exercise the December 2024 SIV Warrants prior to April 24, 2025, and the December 2024 SIV Warrants will expire April 24, 2030. The Company determined the fair value of the warrants by using a BSM option pricing model, with the following assumptions:


Expected term (years)	5.38
Stock price	$	139.94
Volatility	97.50		%
Risk-free rate	4.08		%
Dividend yield	0.00		%

The Company capitalized cash debt issuance costs of $0.1 million in relation to the November 2024 Amendment. The debt issuance costs, including $0.7 million allocated from the Investor Warrants and $0.5 million related to the December 2024 SIV Warrants, and $0.3 million debt premium for the second tranche of the October 2024 Convertible Note were amortized over the term of the October 2024 Convertible Note, until the September 2025 Amendment discussed below, using an effective interest rate of 348%. The debt premium of $0.7 million related to the first tranche of the October 2024 Convertible Note was amortized over the term of the October 2024 Convertible Note, prior to the September 2025 Amendment, using an effective interest rate of (18)%.

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 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 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 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 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
Exercise price	$	132.27		$	19.81
Volatility	87.50		%	87.50		%
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.

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		%
Dividend yield	0.00		%

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 year ended December 31, 2025, the Company converted $1.2 million of principal and $0.3 million of accrued interest on the July 2024 Convertible Note and the October 2024 Convertible Note into 77,087 shares of Class A common stock. Other than the conversion on May 20, 2025 discussed above, the conversions were accounted for under ASC Sub-Topic 470-20, with no gain or loss recognized. The Company paid $0.1 million to pay off the July 2024 Convertible Note in December 2025.

As of December 31, 2025, the October 2024 Convertible Note has a carrying value of $2.4 million, consisting of principal of $2.4 million, net unamortized discount of $0.03 million, and accrued interest of $0.3 million. The October 2024 Convertible Note has future scheduled maturities of $2.4 million in 2026. For the year ended December 31, 2025, interest recognized on the SIV Convertible Notes totaled $0.1 million. This amount consists of cash interest expense of $0.5 million partially offset by non-cash amortization of net debt premiums of $0.4 million. For the year ended December 31, 2024, interest recognized on the SIV Convertible Notes totaled $0.2 million. This amount consists of cash interest expense of $0.1 million partially offset by non-cash amortization of net debt discounts of $0.1 million.

Term Loan

On February 22, 2021, the Company entered into a Term Loan and Security Agreement (the “Term Loan”) with Western Technology Investment which provided the Company with up to $40.0 million in borrowing capacity at an annual interest rate of 12.0%. The Company borrowed $25.0 million of the Term Loan at inception of the agreement on March 1, 2021. The remaining $15.0 million of borrowing capacity is no longer available as the Company did not achieve certain milestones by the June 30, 2021, deadline. The repayment terms of the Term Loan provide for interest-only payments from March 1, 2021, through February 28, 2022.

Under the original terms, the principal amount was due and payable on March 1, 2022. However, during January 2022 the Company exercised its option to pay back the principal amount of the Term Loan over two years beginning on March 1, 2022, and ending on February 28, 2024.

The Company allocated the proceeds from the Term Loan agreement to the note and warrants issued in conjunction with the Term Loan comprising the financing agreement based on the relative fair value of the individual securities on the February 22, 2021, closing date of the agreements. The discount attributable to the note, an aggregate of $15.8 million, primarily related to the value of the warrant liability with immaterial issuance costs, was amortized using the effective interest method over the term of the note, originally maturing on March 1, 2022, but amended to being repaid over two years, recorded as interest expense. Because the discount on the note exceeds 62.6% of its initial face value, and because the discount is amortized over the period from issuance to maturity, the calculated effective interest rate up until January 2022 was 126.0%.

As a result of the exercised extended repayment schedule, the unamortized discount and issuance costs were recast over the updated term of the loan and resulted in a recalculated effective interest rate of 28.2%. Interest expense amortization related to the Term Loan was zero and $0.05 million for the years ended December 31, 2025 and 2024, respectively.

In January 2024, the Company repaid the remaining principal balance of the Term Loan.

Leases [Abstract]

Leases

Note 6. Leases

The Company leases office space under non-cancellable operating leases. In January 2021, the Company commenced a lease in San Jose, California. Due to an event of default under the lease occurring in October 2024, and the likelihood of the landlord executing its right to early terminate the lease as a result, the Company determined this represented a remeasurement event and remeasured the lease as of December 31, 2024. On February 26, 2025, the landlord executed its option to terminate the lease early on March 31, 2026. In December 2025, the Company commenced another lease in San Jose, California. This lease has an expiration date in September 2032.

The components of operating lease expense were as follows:

Variable lease expense		660		600

Total lease expense		$	1,946	$	2,144

Variable lease expense consists of the Company’s proportionate share of operating expenses, property taxes, and insurance.

As of December 31, 2025, the weighted-average remaining lease term was 6.5 years and the weighted-average discount rate was 16.2%.

Earnings Per Share [Abstract]

Net Loss Per Share

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 years ended December 31, 2025 and 2024, 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:


	Year Ended December 31,
		2025	2024
Preferred shares outstanding		306,672	—
Options and unvested stock units outstanding		45,028	410
Warrants outstanding		1,124,725	158,242
Convertible promissory notes		238,031	40,080
