AST SpaceMobile, Inc.

DECEMBER 31, 2025

Organization and Nature of Operations

AST SpaceMobile, Inc., collectively with its subsidiaries (“SpaceMobile” or the “Company”) is currently designing, developing and manufacturing the constellation of BlueBird (“BB”) satellites and has begun launching its planned space-based Cellular Broadband network distributed through a constellation of low Earth orbit (“LEO”) satellites. Once deployed and operational, the BB satellites are designed to provide connectivity directly to off-the-shelf and unmodified devices at broadband speeds (the “SpaceMobile Service”), and be accessible for other applications for government use. At that point, the Company intends to offer the SpaceMobile Service to cellular subscribers and others through wholesale commercial agreements with cellular service providers. The Company also intends to leverage its patented technology, including large phased array and high power capability of its BB satellites, for a variety of applications in the government sector. The Company is headquartered in Texas where it operates satellite assembly, integrating and testing (“AIT”) facilities. The Company also has engineering and development centers elsewhere in the United States, India and Scotland, and engineering, development and production centers in Spain and Israel. The Company’s global footprint was approximately 450,000 square feet as of December 31, 2025. The Company’s intellectual property (“IP”) portfolio is diverse, containing numerous and various innovations of the direct-to-cell satellite ecosystem from space to Earth. The Company’s IP portfolio consists of 38 patent families worldwide. As of December 31, 2025, the Company has appr oximately 3,850 patent and patent pending claims worldwide, of which approximately 1,900 have been officially granted or allowed.

The Company launched its BlueWalker 3 (“BW3”) test satellite on September 10, 2022, and announced the completion of the deployment of the communication phased array antenna of the BW3 test satellite in orbit on November 14, 2022. Using the BW3 test satellite, the Company successfully completed two-way 5G voice calls directly to standard unmodified smartphones, achieved repeated successful download speeds of above 21 megabits per second (“Mbps”) to standard unmodified smartphones and spectral efficiency of approximately 3 bits per second per hertz. The Company has also successfully completed initial in-orbit and ground testing for non-communication government applications. The Company intends to continue testing capabilities of the BW3 test satellite, including further testing with cellular service providers and the government.

The Company launched five first generation commercial BB satellites (“Block 1 BB satellites”) on September 12, 2024. The Block 1 BB satellites are of similar size and weight to the BW3 test satellite and have ten times higher throughput than the BW3 test satellite. In October 2024, the Company completed the deployment of the phased array antennas and Q/V antennas in orbit and performed a series of monitoring tests and activities to confirm the successful initial operations of the Block 1 BB satellites. In January 2025, the Company successfully made the first SpaceMobile video call from space with Vodafone using standard unmodified 4G/5G smartphones. In February 2025, the Company completed the voice and video calls tests on standard unmodified smartphones with AT&T and Verizon in the U.S. and also completed the tests for non-communication applications for the United States government. All five Block 1 BB satellites have participated in the tests at various stages. In April 2025, together with Rakuten Mobile, Inc., the Company successfully conducted a two-way broadband video call in front of a live audience using unmodified smartphones on the SpaceMobile network enabled by a Block 1 BB satellite in orbit today. On July 21, 2025, the Company and AT&T made the first-ever Voice over LTE (“VoLTE”) call and short message service over satellite using AT&T’s spectrum and core network with a standard unmodified cell phone. On October 2, 2025, together with Bell Canada, the Company achieved Canada’s first-ever space-based 4G VoLTE voice call, broadband data connection, and video streaming using everyday smartphones. The Company has deployed and released many fixed cells over the continental U.S. to its Mobile Network Operators (“MNOs”) and Original Equipment Manufacturer partners as the reference cells for routing testing. The Company continues to test the spectrum quality of those fixed cells and have received approval to activate fixed cells from an MNO. The Company expects to continue testing for SpaceMobile Service automation including beta testing prior to rollout of initial noncontinuous SpaceMobile Service in select markets including the United States, Europe, and Japan.

The Company launched the first (“BB6”) of its next generation commercial BB satellites (“Block 2 BB satellites”) on December 23, 2025. The Block 2 BB satellites feature an up to approximately 2,400 square feet phased array, the largest phased array ever deployed in a LEO for commercial use, which is more than three times larger than the phased array of the Block 1 BB satellites and designed to deliver up to 10 times the bandwidth capacity of the Block 1 BB satellites. On February 10, 2026, the Company successfully deployed BB6, the largest phased array deployed commercially in LEO. The performance of BB6 is driven by several breakthroughs in space-based architecture. The large antenna array allows the satellite to transmit and receive signals from standard handheld devices. Further, the large aperture enables highly precise beamforming, creating narrower, more focused coverage areas. This precision minimizes interference, maximizes network capacity and provides a consistent high-quality user experience for Cellular Broadband services, including voice, data and video.

The Company is organized in an “Up-C” structure in which the business is operated by AST & Science, LLC (“AST LLC”) and its subsidiaries and in which the Company's only direct assets consist of equity interests in AST LLC. As the managing member of AST LLC, the Company has full discretion to manage and control the business of AST LLC and to take all action it deems necessary to accomplish the purposes of AST LLC. The Company’s Class A Common Stock is listed on the Nasdaq Capital Market under the symbol “ASTS”.

Summary of Significant Accounting Policies

Basis of Presentation and Principles of Consolidation

The accompanying consolidated financial statements and related notes have been prepared by the Company in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) and the requirements of the Securities and Exchange Commission (“SEC”). The consolidated financial statements include the accounts of the Company, AST LLC and its subsidiaries. Intercompany transactions and balances have been eliminated upon consolidation. Certain comparative amounts have been reclassified to conform to the current period presentation. These reclassifications had no effect on the reported results of operations.

As the Company is the sole managing member of AST LLC and has full, exclusive and complete discretion to manage and control the business of AST LLC and to take all actions it deems necessary, appropriate, advisable, incidental, or convenient to accomplish the purposes of AST LLC, the financial statements of AST LLC and its subsidiaries have been prepared on a consolidated basis with the Company.

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. The Company bases its estimates and assumptions on historical experience when available and on other market-specific or other relevant assumptions that it believes to be reasonable under the circumstances. Significant estimates and assumptions reflected in these financial statements include, but are not limited to, useful lives assigned to property and equipment, the fair values of warrant liabilities, potential impairment of long-lived assets and indefinite-lived intangibles, and equity-based compensation expense. The Company assesses estimates on an ongoing basis; however, actual results could materially differ from those estimates due to risks and uncertainties, including the continued uncertainty surrounding rapidly changing market and economic conditions due to geopolitical conflicts and macroeconomic conditions including changes in inflation and interest rates.

Related Parties and Related Party Transactions

A related party is a person who has the ability to exert significant influence over the Company and may include executive officers and directors, including members of their immediate families, shareholders owning more than 10% of the Company’s voting securities, or other entities deemed to be affiliates, as defined in Accounting Standards Codification (“ASC”) 850, Related Party Disclosures (“ASC 850”). The Company assesses its related parties and applicable disclosures on a quarterly basis, considering all relevant facts and circumstances.

According to the Company’s Stockholders’ Agreement, as amended, certain investors of the Company have the right to nominate directors to the Company’s Board of Directors. These investors include AT&T, Vodafone, American Tower and Antares Technologies. However, none of these investors have ownership rights or any voting rights that qualify them as related parties under ASC 850. Therefore, the Company has concluded that none of these investors with board representation are related parties as of December 31, 2025, and no disclosures under ASC 850 are required for these investors.

On July 7, 2025, the Company and Vodafone entered into an agreement to create a jointly-owned European satellite service business (“SatCo”). As an equity method investee, SatCo is a related party of the Company under ASC 850. See Note 16 Vodafone Joint Venture for further details.

Foreign Currency Translation and Transaction Gains and Losses

The financial statements of the Company’s foreign subsidiaries are translated from local currency into reporting currency, which is U.S. dollars, using the current exchange rate at the balance sheet date for assets and liabilities, and the weighted average exchange rate prevailing during the period for revenues and expenses. The functional currency of the Company’s foreign subsidiaries is the local currency for each entity and, accordingly, translation adjustments for these subsidiaries are included in accumulated other comprehensive income (loss) within stockholders’ equity. Realized and unrealized gains and losses resulting from foreign currency transactions denominated in currencies other than the functional currency are reflected as other (expense) income, net in the consolidated statements of operations.

Segment

Operating segments are defined as components of an entity for which separate financial information is available and that is regularly reviewed by the Chief Operating Decision Maker (“CODM”) in deciding how to allocate resources to an individual segment and in assessing performance.

The Company’s CODM is its Chairman and Chief Executive Officer. The Company has determined that it operates inone operating segment, as the CODM reviews financial information presented on a consolidated basis for purposes of making operating decisions, allocating resources, and evaluating financial performance. Consolidated net loss before allocation to noncontrolling interest is the reported measure of segment profit or loss and is the primary measure used by the CODM to assess segment performance and decide how to allocate resources. This measure is used to monitor operating results, compare actual performance to internal budgets and forecasts, evaluate performance relative to strategic objectives, and determine the level of operating and capital resources required. Consolidated net loss before allocation to noncontrolling interest is presented in the consolidated statements of operations as revenues less total operating expenses and other segment items. Other segment items include loss and gain on remeasurement of warrant liabilities, interest income and expense, and income taxes expense. Other segment items also include induced conversion expense related to the repurchases of the 20324.25% Convertible Notes, loss on extinguishment of debt, and a charge for penalty paid in accordance with a contractual agreement for the years ended December 31, 2025, 2024 and 2023, respectively. The measure of segment assets is reported on the accompanying consolidated balance sheets as total assets.

Cash and Cash Equivalents

The Company’s cash equivalents consist of short-term money market funds. The Company considers all highly liquid investments with a maturity date of 90 days or less at the date of purchase to be cash equivalents. Cash is primarily maintained at Federal Deposit Insurance Corporation (“FDIC”) insured financial institutions. The Company maintains its cash in accounts at financial institutions that the Company believes are of high credit quality. At times, the cash balance may exceed federally insured limits. The Company's foreign subsidiaries may deposit cash at institutions that are not insured by the FDIC. Interest income earned on cash and cash equivalents and restricted cash is reported under interest income in the consolidated statement of operations. Cash and cash equivalents and restricted cash as of December 31, 2025 are subject to minimal credit risk.

Restricted Cash

Restricted cash represents cash held in escrow and deposit accounts. These funds are restricted as to withdrawal or use under the terms of the contractual agreements.

Property and equipment are carried at cost less accumulated depreciation. The cost of self-constructed BB satellite assets consists of direct materials, direct labor, launch costs, and other direct costs attributable to bringing the asset to a working condition and desired location for the intended use. Costs incurred, including direct materials purchased, launch payments made, direct labor costs and overheads such as launch insurance and satellite transportation costs to the launch site, until the completion of the construction and launch of the BB satellites are reported as satellite materials, satellites under construction, and advance launch payments within construction-in-progress. Once launched in orbit, the costs of the BB satellites are reported as satellites in orbit and depreciation of the satellites commences once the BB satellites are ready for their intended use. To date, the Company has capitalized five Block 1 BB satellites which are reported as part of satellites in orbit within property and equipment. The Block 1 BB satellites were reclassified from Construction in progress to Satellites in orbit as of October 29, 2024, the date they were determined to be ready for their intended use, and are depreciated over their expected remaining useful lives of approximately 60 months.

The Company capitalizes the costs of the test satellites if there is an alternative future use for the test satellites. The Company capitalizes only those expenditures and ancillary costs that are directly attributable to assembly and testing and necessarily incurred to place the test satellites into their intended location and use. These costs include materials costs, launch cost, and other non-recurring costs directly associated with the development of the test satellites. The other non-recurring costs primarily include third-party vendors who are hired solely for the design, assembly, and testing of the test satellite and are responsible for the value and progression of the project. The costs for internal recurring engineering employees and consultants are expensed as engineering services costs and not capitalized to the cost of the test satellites, as these employees are not directly associated with the development of the test satellites. To date, the Company has capitalized one test satellite, BW3, which is reported as part of satellites in orbit within property and equipment. BW3 test satellite was capitalized in 2023 and has been fully depreciated in August 2024.

The Company capitalizes the costs of software obtained for internal use in accordance with the guidance for accounting for costs of computer software obtained for internal use. Capitalization of software obtained for internal use commences during the development phase of the project and ends when the asset is ready for its intended use. Software obtained for internal use is generally amortized on a straight-line basis over the estimated useful life and included within property and equipment on the Company’s consolidated balance sheet. Capitalized costs of software obtained for internal use for the years ended December 31, 2025,2024 and 2023 were $17.5 million, $13.5 million and $7.0 million, respectively, all of which were developed by third parties to the Company. Amortization of capitalized internal use software for the years ended December 31, 2025 and 2024 was approximately $1.4 million and $1.1 million, respectively. No amortization was recognized for the year ended December 31, 2023.

The Company records depreciation in a manner that recognizes the cost of its depreciable assets over their estimated useful lives primarily using the straight-line method. Leasehold improvements are amortized over the shorter of the terms of the underlying leases or the estimated useful lives of the improvements. Repairs and maintenance costs that do not extend the useful life or enhance the productive capacity of an asset are expensed as incurred. Upon retirement or disposal of property and equipment, the Company derecognizes the cost and accumulated depreciation balance associated with the asset, with a resulting gain or loss from disposal included in the determination of net income or loss.

The Company depreciates the assets over the estimated useful lives as follows:

(1)

Includes vehicles, furniture and fixtures, and a phased array test facility.

Cloud Computing Software Implementation Costs

Cloud computing software implementation costs incurred in hosting arrangements are capitalized and reported as a component of Other current assets and Other non-current assets in the Company’s consolidated balance sheets. Once available for their intended use, these costs are amortized on a straight-line basis over their respective contract service periods, including periods covered by any reasonably probable options to extend, ranging from three to five years. As of December 31, 2025 and 2024, capitalized costs, net of accumulated amortization, totaled $2.9 million and $0.7 million, respectively. For the years ended December 31, 2025, 2024 and 2023, amortization expense associated with hosting arrangements was $0.4 million, $0.8 million and $0.2 million, respectively, and recognized within General and administrative costs in the consolidated statements of operations.

Impairment of Long Lived Assets

Long-lived assets consist of property and equipment and operating lease right-of-use assets. Long-lived assets are tested for recoverability whenever events or changes in business circumstances indicate that the carrying amount of the asset may not be fully recoverable. The Company continually evaluates whether events or circumstances have occurred that indicate that the estimated remaining useful life of long-lived assets may warrant revision or if events or circumstances indicate that the carrying value of these assets may be impaired. To compute whether assets have been impaired, the estimated undiscounted future cash flows for the estimated remaining useful life of the assets are compared to the carrying value. To the extent that the future cash flows are less than the carrying value, the assets are written down to the estimated fair value of the asset. There wereno impairment charges for long-lived assets recognized for theyears ended December 31, 2025, 2024 and 2023.

The Company accounts for warrants as either equity-classified or liability-classified instruments based on an assessment of the warrant’s specific terms and applicable authoritative guidance in ASC 480, Distinguishing Liabilities from Equity (“ASC 480”), and ASC 815, Derivatives and Hedging (“ASC 815”). Management’s assessment considers whether the warrants are freestanding financial instruments pursuant to ASC 480, whether they meet the definition of a liability pursuant to ASC 480, and whether the warrants meet all of the requirements for equity classification under ASC 815, including whether the warrants are indexed to the Company’s own Common Stock and whether the warrant holders could potentially require “net cash settlement” in a circumstance outside of the Company’s control, among other conditions for equity classification. This assessment, which requires the use of professional judgment, is conducted at the time of warrant issuance and as of each subsequent quarterly period-end date while the warrants are outstanding.

Issued or modified warrants that meet all of the criteria for equity classification are recorded as a component of additional paid-in capital at the time of issuance. Issued or modified warrants that do not meet all the criteria for equity classification are recorded as a liability at their initial fair value on the date of issuance and subject to remeasurement each balance sheet date with changes in the estimated fair value of the warrants to be recognized as an unrealized gain or loss in the consolidated statements of operations.

Fair Value Measurements

The Company measures certain assets and liabilities at fair value, either upon initial recognition or for subsequent accounting or reporting. The fair value of the financial instruments is not necessarily representative of the amount that could be realized or settled, nor does the fair value amount consider the tax consequences of realization or settlement. In assessing the fair value of financial instruments, the Company uses a variety of methods and assumptions, which are based on estimates of market conditions and risks existing at the time.

The Company uses the following valuation techniques to measure fair value for its assets and liabilities:

•

Level 1: Quoted prices in active markets for identical assets and liabilities.

•

Level 2: Observable inputs other than Level 1 inputs. Examples of Level 2 inputs include quoted prices in active markets for similar assets or liabilities, quoted prices for identical assets or liabilities in markets that are not active, inputs other than quoted prices that are observable such as interest rate and yield curves, and market-corroborated inputs.

•

Level 3: Unobservable inputs based on the Company's assessment of the assumptions that market participants would use in pricing the asset or liability.

Revenue Recognition

Revenue generated from sales of goods and services is recognized when a customer obtains control of promised goods or services in accordance with ASC 606, Revenue from Contracts with Customers. During the years ended December 31, 2025, 2024 and 2023, the Company recognized$44.4 million,$0.5 million and $0 million of Products revenue fromthe sale of gateway equipment and related software to MNOs. These arrangements typically involve multiple performance obligations, which include hardware, software, and optional installation and support services. Revenue for hardware and software sales is recognized at a point in time when control transfers to the customer, which is generally upon delivery of the equipment and activation of the software. Revenue for installation and support services is generally recognized as services are performed.

During the years ended December 31, 2025, 2024 and 2023, the Company recognized$26.5 million ,$3.9 million, and $0 million of Services revenue mainly from performance obligations completed under agreements with the U.S. Government to date either directly as a prime contractor or indirectly through prime contractors. Under these arrangements, the Company has provided testing and other development services designed to enable future service capabilities. These contracts typically contain a single performance obligation and include a series of fixed-price milestones for which the Company has the right to invoice upon completion and customer acceptance. The Company recognizes revenue from these contracts over time when milestones are achieved and accepted by the customer, which reflects the pattern by which the Company satisfies its performance obligation through the transfer of service to the customer.

Additionally, the Company has definitive commercial agreements with MNOs to provide SpaceMobile Service. These arrangements contain multiple performance obligations, including sale of gateway equipment hardware and software and a stand ready obligation to provide SpaceMobile Service. Revenue for SpaceMobile Service will be recognized over the life of the contract, beginning when AST provides MNOs access to its satellite network. To date, the Company has not recognized any revenues from its SpaceMobile Service.

The Company defers revenue and recognizes contract liabilities in the event the performance obligations are not satisfied for which payment has been received. As of December 31, 2025 and December 31, 2024,$227.0 million and $42.0 million, respectively, of current and non-current contract liabilities were recorded for advance consideration received from customers for which the associated performance obligations were not yet satisfied. The significant increase in contract liabilities during the year ended December 31, 2025 was primarily due to advance payments received from MNOs related to the provision of SpaceMobile Service. The amount of revenue recognized for the year ended December 31, 2025 that was included in the December 31, 2024 contract liability balance was approximately $6.4 million.

Revenue allocated to remaining performance obligations, which includes contract liabilities and amounts that will be invoiced and recognized as revenue in future periods, was approximately $1.2 billion as of December 31, 2025. The Company expects to recognize approximately 9.0%of its remaining performance obligations as revenue over the next 12 months and the remainder thereafter. The Company’s contracts with MNOs to provide SpaceMobile Service contain multiple performance obligations. Revenue allocated to remaining SpaceMobile Service performance obligations does not include variable consideration that has not been included in the transaction price, specifically consideration from revenue sharing with MNOs based on revenue generated from end customers’ usage of the satellite services. That consideration is constrained due to the uncertainty about the amount of the consideration to be received, which may not be resolved for a period of time.

Intangible Assets

The Company’s intangible assets consist of the spectrum usage rights of up to 45 MHz of lower mid-band satellite spectrum in the United States and Canada for direct-to-device satellite applications and certain S-Band International Telecommunication Union (“ITU”) priority rights to Mobile Satellite Services frequencies in the range of 1980-2010 MHz and 2170-2200 MHz, for use in LEO. The Company capitalizes spectrum payments, regulatory filing and other direct costs incurred to ready the spectrum usage rights for their intended use as an intangible asset. The Company will commence amortization of the spectrum usage rights once applicable regulatory approvals are received and the asset is considered ready for its intended use. The Company determined that the S-Band ITU priority rights is an indefinite-lived intangible asset as there are currently no legal, regulatory, contractual, competitive, economic or other factors that limit the useful life of its priority rights. The Company will re-evaluate the useful life determination each year to determine whether events and circumstances continue to support an indefinite useful life. The Company tests its definite and indefinite-lived intangible assets for potential impairment annually or more frequently if impairment indicators are present. The Company has the option to first perform a qualitative assessment to determine whether it is necessary to perform a quantitative impairment test. However, the Company may elect to bypass the qualitative assessment in any period and proceed directly to performing the quantitative impairment test. See Note 14 Spectrum Usage Rights and Related Financing and Note 15 Global S-Band Spectrum Priority Rights Acquisition for further details.

Accounts Receivable and Allowance for Credit Losses

Accounts receivable are reported net of an allowance for credit losses that are not expected to be recovered. The Company recognizes the allowance for credit losses at inception of sales and reassesses quarterly based on management’s expectation of the asset’s collectability. The allowance is based on multiple factors including historical experience with bad debts, the credit quality of the customer base, the aging of such receivables and current macroeconomic conditions. The Company elected the practical expe dient, available as part of the early adoption of ASU 2025-05 (see below), not to consider management’s expectations of conditions in the future for current accounts receivable and current contract assets arising from transactions accounted for under ASC 606. The Company’s contractual payment terms with its customers average between 60 to 90 days. As of December 31, 2025, the majority of outstanding accounts receivable are considered current. For the years ended December 31, 2025 and 2024, the Company’s customers had high credit ratings and the allowance for credit losses was immaterial.

Inventory

Inventory consists of gateway equipment held for sale and is stated at the lower of cost or net realizable value. Cost is determined using the weighted-average cost method and includes the average purchase price of equipment acquired, inbound freight, and other direct costs necessary to prepare the equipment for sale. Net realizable value represents the estimated selling price in the ordinary course of business less reasonably predictable costs of completion, disposal, and transportation.

The Company periodically reviews inventory on hand and records provisions for excess, slow-moving, or obsolete inventory based on historical usage, expected demand, and technological obsolescence among other factors. Inventory write-downs are recorded as a component of cost of revenues and are not subsequently reversed.

Engineering services costs are charged to expense as incu rred. Engineering services costs consist primarily of the cost of employees and consultants involved in designing and developing the BB satellites, managing the network and satellite operations centers, and indirectly supporting the assembly, integration and testing of the BB satellites, license cost, and general expenses related to AIT facilities and engineering development centers.

General and administrative costs primarily consist of compensation and related expenses for non-engineering personnel, office and facilities expenses, and professional services, including legal fees, accounting, and public relations. These costs also include insurance, software licensing and subscriptions.

Research and development costs are charged to expense as incurred. Research and development costs consist principally of development activities in which the Company typically engages third-party vendors for the design and development of the electronic componentry, software, and mechanical deployment systems and materials and supplies consumed in the development activities.

Stock-Based Compensation

The Company accounts for equity awards, including grants of stock options, restricted stock and restricted stock units, in accordance with ASC 718, Compensation – Stock Compensation (“ASC 718”). ASC 718 requires all equity-based payments to employees, which includes grants of employee equity awards, to be recognized in the consolidated statements of operations based on their grant date fair values. The Company issues stock-based compensation awards to the employees, non-employees, and non-employee members of the Board of Directors. The Company accounts for stock-based compensation for awards granted to non-employees in a similar fashion to the way it accounts for stock-based compensation awards to employees.

The Company estimates the grant date fair value of stock options granted to employees, non-employees, and non-employee members of the Board of Directors using the Black-Scholes option-pricing model. Use of the Black-Scholes model requires the Company to make assumptions with respect to the expected term of stock options, the expected volatility of the Common Stock consistent with the expected life of the option, risk-free interest rates and expected dividend yields of the Common Stock. The fair value of restricted stock and restricted stock units granted to employees, non-employees and non-employee members of the Board of Directors is based on the fair value of the Company’s stock on the grant date. For awards that vest based solely on achievement of a service condition, the Company recognizes expense on a straight-line basis over the period during which the award holder provides such services. For awards that vest based on both service and performance conditions, the Company recognizes expense using a graded method for such awards only to the extent it believes achievement of the performance conditions is probable. The Company recognizes forfeitures as they occur and reverses any previously recognized compensation cost associated with forfeited awards. The Company accounts for the compensation associated with equity awards by offsetting expense with additional paid-in capital.

The Company’s less than wholly owned subsidiary, AST LLC, has issued stock-based compensation awards to its employees, non-employees, and non-employee members of the Board of Directors. The exercise of these awards decreases the Company’s ownership interest in AST LLC. The Company accounts for the compensation associated with these awards similarly to the awards described above; however, the offset to the expense is recorded to noncontrolling interest rather than additional paid-in capital.

Income Taxes

The Company follows the asset and liability method of accounting for income taxes under ASC 740, Income Taxes (“ASC 740”). Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statements carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that included the enactment date.

In assessing the realizability of deferred tax assets, management considered whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income, and tax planning strategies in making this assessment.

ASC 740 prescribes a recognition threshold and a measurement attribute for the recognition and measurement of tax positions taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more likely than not (i.e., a likelihood of more than 50%) to be sustained upon examination by taxing authorities. A recognized tax position is then measured at the largest amount of benefit with greater than 50% likelihood of being realized upon ultimate settlement. The Company recognizes accrued interest and penalties related to uncertain tax positions as income tax expense. There wereno uncertain tax positions andno amounts accrued for interest and penaltiesas of December 31, 2025 and 2024. The Company is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its position.

Noncontrolling Interests

Thenoncontrolling interests primarily represent the equity interest in AST LLC held by members other than the Company. Changes in the Company’s ownership interest in AST LLC while retaining control of AST LLC are accounted for as equity transactions.

Incomeor loss is attributed to the noncontrolling interests based on their contractual distribution rights, and the relative percentages of equity interest held by the Company and the other members during the period.

Net Loss per Share

The Company reports both basic and diluted net loss per share. Basic net loss per share is calculated based on the weighted average number of shares of Common Stock outstanding and excludes the dilutive effect of warrants, stock options, and other types of convertible securities. Diluted net loss per share is calculated based on the weighted average number of shares of Common Stock outstanding and the dilutive effect of stock options, warrants and other types of convertible securities is included in the calculation. Dilutive securities are excluded from the diluted net loss per share calculation in periods where the Company reports a net loss as such dilutive securities have an anti-dilutive effect on net loss per share.

Recently Adopted and Issued Accounting Pronouncements

In November 2024, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2024-04, Induced Conversions of Convertible Debt Instruments, which clarifies the requirements for determining whether certain settlements of convertible debt instruments should be accounted for as an induced conversion. This ASU is effective for fiscal years beginning after December 15, 2025 and interim reporting periods within those annual reporting periods. The Company early adopted the new standard, effective January 1, 2025, on a prospective basis, and the accounting requirements of this ASU have been reflected in the Company’s accounting for the repurchase of a portion of the 20324.25% Convertible Notes in the consolidated financial statements.

In July 2025, FASB issued ASU 2025-05, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets (“ASU 2025-05”), which amends ASC 326-20, Financial Instruments – Credit Losses – Measured at Amortized Cost to introduce a practical expedient that permits entities to assume that current conditions as of the balance sheet date do not change for the remaining life of current accounts receivable and/or current contract assets arising from transactions accounted for under ASC 606. The standard is effective for annual periods beginning after December 15, 2025, including interim periods within those annual periods. The Company early adopted the new standard, effective January 1, 2025, on a prospective basis, and the accounting requirements of this ASU have been reflected in the Company’s evaluation of allowance for accounts receivable in the consolidated financial statements.

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740), Improvements to Income Tax Disclosures (“ASU 2023-09”). ASU 2023-09 requires a public business entity (PBE) to disclose, on an annual basis, a tabular rate reconciliation using both percentages and currency amounts, broken out into specified categories with certain reconciling items further broken out by nature and jurisdiction to the extent those items exceed a specified threshold. In addition, all entities are required to disclose income taxes paid, net of refunds received disaggregated by federal, state/local, and foreign and by jurisdiction if the amount is at least 5% of total income tax payments, net of refunds received. The Company adopted the ASU for annual periods beginning January 1, 2025 and the adoption did not have a material impact on the Company’s consolidated financial statements.

Future Adoption of Recently Issued Accounting Pronouncements

In November 2024, the FASB issued ASU 2024-03, Income Statement – Reporting Comprehensive Income – Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses, which is intended to improve the disclosures of expenses by providing more detailed information about the types of expenses in commonly presented expense captions. The standard is effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027. Early adoption is permitted. The standard can be applied either prospectively or retrospectively. The Company is currently evaluating the impact of adopting this ASU on the presentation of its consolidated financial statements.

In September 2025, FASB issued ASU 2025-06, Intangibles – Goodwill and Other – Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software (“ASU 2025-06”). ASU 2025-06 modernizes the accounting for internal-use software costs by eliminating the prescriptive "project stage" model and introducing a principles-based framework that is intended to better reflect current software development practices. The amendment is effective for annual reporting periods beginning after December 15, 2027, and interim reporting periods within those annual reporting periods. Early adoption is permitted. The Company is currently evaluating the potential impacts of adopting this ASU on its consolidated financial statements.

All other new accounting pronouncements issued, but not yet effective or adopted, have been deemed to be not relevant to the Company and, accordingly, are not expected to have a material impact once adopted.

Fair Value Measurement

The Company’s financial assets and liabilities measured at fair value on a recurring basis were as follows (in thousands):

As of December 31, 2025 and December 31, 2024, the Company had$2.8 billion and$567.5 million of cash and cash equivalents and restricted cash, respectively, of which$2.0 billion and$510.4 million, respectively, were classified as cash equivalents, which consisted principally of short-term money market funds with original maturities of 90 days or less. As of December 31, 2025, non-current restricted cash of $443.4 million consisted of the cash collateral for the UBS Bridge Financing Loan and $15.0 million collateral for the capital equipment loan with Prosperity Bank, and current restricted cash of $0.9 million consisted of deposits against the bank guaranty issued to the landlords for lease of properties. As of December 31, 2024, restricted cash of $2.5 million consisted of a deposit into an interest reserve escrow account for the terminated senior secured credit facility and a deposit against the bank guaranty issued to the landlord for lease of a property. For certain instruments, including cash, accounts payable, and accrued expenses, it was estimated that the carrying amount approximated fair value because of the short maturities of these instruments.

As of December 31, 2025 and December 31, 2024, warrant liabilities were comprised of private placement warrants (“Private Placement Warrants”), which have been classified as Level 3 due to the use of historical volatility of the Company’s shares and implied volatility derived from options on the Company’s shares. Warrant liabilities are described in detail in Note 8 Warrant Liabilities.

The Private Placement Warrants are valued using a Black-Scholes-Merton model. The Company’s Black-Scholes-Merton model to value Private Placement Warrants required the use of the following subjective assumption inputs:

•

As of December 31, 2025, the risk-free rate assumption was based on the three-month and one-year U.S. Treasury rates as the estimated time to expiration was 0.26 years (compared to being based on the one- and two-year U.S. Treasury rates based on an estimated time to expiration of 1.26 years as of December 31, 2024). An increase in the risk-free interest rate, in isolation, would result in an increase in the fair value measurement of the warrant liabilities and vice versa.

•

As of December 31, 2025 and December 31, 2024, the expected volatility assumption was based on an average of the historical volatility of the Company’s shares and the implied volatility of one-year options on the Company’s shares, which was 105.3% and 112.7%, respectively.

Property and equipment, net consisted of the following (in thousands):

Total depreciation and amortization expense for theyears ended December 31, 2025, 2024 and 2023 was approximately$51.1 million,$63.3 million, and$54.5 million, respectively.

Leases

The Company and its subsidiaries are lessees under various operating leases for certain office space, manufacturing facilities and equipment.

The Company recognizes right-of-use assets and lease liabilities associated with lease agreements with an initial term of 12 months or greater, while lease agreements with an initial term of 12 months or less are not recorded in the Company's consolidated balance sheets. When reasonably certain that renewal options will be exercised, the Company includes lease payments associated with such options, including those that are exercisable at its discretion, in the measurement of its operating leases assets and liabilities. Where implicit rates are not included in the lease agreement, the Company determines the incremental borrowing rate at lease commencement date based on various factors, including the yields on non-investment grade of debt available in the marketplace for the same term as the associated lease.

Midland Lease

On November 13, 2018, AST LLC entered into both an Economic Development Agreement (the “EDA”) and a sublease agreement with Midland Development Corporation.

AST LLC will act as a limited guarantor under the UBS Loan Facility solely upon the occurrence of certain “bad boy” actions adverse to the lender by AST LLC or its affiliates, and the lender’s recourse to the assets of AST LLC is limited to AST LLC’s equity interests in BackstopCo. In addition, the affirmative and negative covenants contained in the UBS Loan Agreement (as described further below), apply to BackstopCo and/or AST LLC, as applicable.

As of December 31, 2025 and December 31, 2024, warrant liabilities were comprised of Private Placement Warrants. Each whole Private Placement Warrant entitles the registered holder to purchase one whole share of Class A Common Stock at a price of $11.50 per share and is exercisable on a cashless basis. Pursuant to the warrant agreement, a holder of Private Placement Warrants may exercise its warrants only for a whole number of shares of Class A Common Stock. This means that only a whole warrant may be exercised at any given time by a warrant holder. The Private Placement Warrants expire on April 6, 2026, five years after the Business Combination, at 5:00 p.m., New York City time, or earlier upon liquidation.

During the year ended December 31, 2025,2,931,125 Private Placement Warrants were exercised for 2,294,380 shares of Class A Common Stock on a cashless basis. As of December 31, 2025, there were 122,000 Private Placement Warrants that remained outstanding.

Commitments and Contingencies

Purchase Commitments

As of December 31, 2025, the Company has purchase commitments of approximately$489.1 million primarily related to procurement of BB satellite components, research and development (“R&D”) programs, operational services and capital improvements. None of these purchase commitments are considered unconditional purchase obligations as the Company has various rights to adjust the quantity of satellite components on the purchase orders and/or change the delivery timelines in accordance with its ongoing business plan. The Company also has rights to terminate certain purchase commitments and potentially incur a termination fee in certain cases. In addition, the Company has launch agreements under which payments are due at scheduled milestones over the duration of the agreements. The Company has contractual rights to cancel these launches or terminate the related agreements at any time by paying a termination fee, and in certain cases without incurring a termination fee, and any excess payments made to the launch providers for these launches will be refunded to the Company. As of December 31, 2025, the Company had minimum commitments of approximately$250.0 -$325.0 million related to future launches, none of which are considered unconditional purchase obligations.

Legal Proceedings

The Company is subject to various legal proceedings and claims that have arisen in the ordinary course of business and that have not been fully adjudicated. In the opinion of management, there was not at least a reasonable possibility the Company may have incurred a material loss, or a material loss in excess of any recorded accrual, with respect to loss contingencies. However, the outcome of litigation is inherently uncertain. Therefore, although management considers the likelihood of such an outcome to be remote, if one or more of these legal matters were resolved against the Company in a reporting period for amounts in excess of management’s expectations, the Company’s consolidated financial statements for that reporting period could be materially adversely affected.

The existing equity holders (other than Mr. Avellan) at the time of the Business Combination own economic interests in AST LLC which are redeemable into either shares of Class A Common Stock on a one-for-one basis or cash at the option of the Company. Upon redemption of the AST LLC Common Units by the existing equity holders (other than Mr. Avellan), a corresponding number of shares of Class B Common Stock held by such existing equity holders will be cancelled. During the year ended December 31, 2024, the existing equity holders redeemed 38,814,465 AST LLC Common Units into Class A Common Stock and subsequently 38,814,465 Class B Common Stock held by such existing equity holders were cancelled.

Shares of Class C Common Stock were issued to Mr. Avellan in connection with the Business Combination and are non-economic, but entitle the holder to the lesser of ten votes per share and the Class C Share Voting Amount, the latter of which is a number of votes per share equal to (1) (x) an amount of votes equal to 88.31% of the total voting power of the outstanding voting stock, minus (y) the total voting power of the outstanding capital stock (other than Class C Common Stock) owned or controlled by Mr. Avellan and his permitted transferees, divided by (2) the number of shares of Class C Common Stock then outstanding (the “Super-Voting Rights”).

The Company is authorized to issue 100,000,000 shares of preferred stock with a par value of $0.0001 per share with such designation, rights and preferences as may be determined from time to time by the Company’s Board of Directors.

Noncontrolling Interest

The noncontrolling interests represent the equity interest in AST LLC held by members other than the Company. Changes in the Company’s ownership interest in AST LLC while retaining control of AST LLC are accounted for as equity transactions. Income or loss is attributed to the noncontrolling interests based on their contractual distribution rights, and the relative percentages of equity interest held by the Company and the other members during the period.

As the sole managing member of AST LLC controlling the operating decisions of AST LLC, the Company consolidates the financial position and results of operations of AST LLC and its subsidiaries. The Company reports equity interest in AST LLC held by members other than the Company as noncontrolling interest in the consolidated balance sheets. The noncontrolling interest is classified as permanent equity within the consolidated balance sheets as the Company may only elect to settle a redemption request in cash if the cash delivered in the exchange is limited to the amount of net proceeds from the issuance and sale of Class A Common Stock from a new permanent equity offering.

Each issuance of the Company's Class A Common Stock is accompanied by a corresponding issuance of AST LLC Common Units to the Company, which results in a change in ownership and reduction in noncontrolling interest. In addition, the Fifth Amended and Restated Limited Liability Company Operating Agreement of AST LLC permits the noncontrolling interest holders of AST LLC Common Units to exchange AST LLC Common Units, together with related shares of the Class B Common Stock or Class C Common Stock, for shares of the Class A Common Stock on a one-for-one basis or, at the election of the Company, for cash (a “Cash Exchange”). A Cash Exchange is limited to the amount of net proceeds from the issuance and sale of Class A Common Stock from a new permanent equity offering. Future redemptions or direct exchanges of AST LLC Common Units by the noncontrolling interest holders will result in a change in ownership and reduce the amount recorded as noncontrolling interest.

As of December 31, 2025 and December 31, 2024, the noncontrolling interest in AST LLC was approximately 23.9% and 30.1% respectively. The decrease in noncontrolling interest percentage during the year ended December 31, 2025 was a result of the issuance of Class A Common Stock in connection with the repurchase of a portion of the 20324.25% Convertible Notes, conversion of the 2034 Convertible Notes, acquisition of certain S-Band ITU priority rights and payment for a portion of the L-band Annual Payment payable in shares, issuance of Class A Common Stock under the 2024 Sales Agreement, the May 2025 Sales Agreement and the October 2025 Sales Agreement, exercises of the Private Placement Warrants, redemptions of AST LLC Common Units in exchange for Class A Common Stock, exercises of options and vesting of restricted stock units.

Stock-Based Compensation

Stock-Based Compensation Expense

Stock-based compensation, measured at the grant date based on the fair value of the award, is typically recognized ratably over the requisite services period, using the straight-line method of expense attribution. The Company recorded stock-based compensation expense in the following categories of its consolidated statements of operations (in thousands):

The Company estimates the fair value of the stock option awards to employees, non-employees and non-employee members of the Board of Directors using the Black-Scholes option pricing model, which requires the input of subjective assumptions, including (i) the expected volatility of the Company's stock, (ii) the expected term of the award, (iii) the risk-free interest rate, and (iv) any expected dividends. Due to the lack of company-specific historical and implied volatility data, the Company based the estimate of expected volatility on the estimated and expected volatilities of a representative group of publicly traded companies. For these analyses, the Company selects companies with comparable characteristics including enterprise value, risk profiles, position within the industry, and with historical share price information sufficient to meet the expected life of the stock-based awards. The Company computes the historical volatility data using the daily closing prices for the selected companies’ shares during the equivalent period of the calculated expected term of the stock-based awards. The Company will continue to apply this process until a sufficient amount of historical information regarding the volatility of the Company’s stock price becomes available. For awards that qualify as “plain-vanilla” options, the Company estimates the expected life of the employee stock options using the “simplified” method, whereby, the expected life equals the average of the vesting term and the original contractual term of the option. The expected term of stock options granted to non-employees is equal to the contractual term of the option award. The risk-free interest rate is determined by reference to the U.S. Treasury yield curve in effect at the time of grant of the award for time periods approximately equal to the expected term of the award. Expected dividend yield is based on the fact that the Company has never paid cash dividends and does not expect to pay any cash dividends in the foreseeable future.

The fair value of restricted stock units or restricted stock granted to employees, non-employees, and non-employee members of the Board of Directors is based on the fair value of the Company’s stock on the grant date. The Company elects to account for forfeitures as they occur rather than apply an estimated forfeiture rate to stock-based compensation expense.

AST LLC 2019 Equity Incentive Plan

Prior to the Business Combination, under the 2019 Equity Incentive Plan (“AST LLC Incentive Plan”), AST LLC was authorized to issue ordinary shares, as well as options exercisable for ordinary shares, as incentives to its employees, non-employees, and non-employee members of its Board of Directors. Following the Business Combination, no further grants were made or will be made under the AST LLC Incentive Plan. In connection with the Business Combination, the existing AST LLC options were reclassified into options to acquire AST LLC Incentive Equity Units, and there was no incremental compensation cost and the terms of the outstanding awards, including fair value, vesting conditions and classification, were unchanged. Each AST LLC Incentive Equity Unit is convertible into one AST LLC Common Unit and each AST LLC Common Unit is redeemable for one share of Class A Common Stock on the later of the (i) 24-month anniversary of the consummation of the Business Combination and (ii) six-month anniversary from the vesting date. The AST LLC Incentive Plan continues to govern the terms and conditions of the outstanding awards granted under it, except that in lieu of ordinary shares, holders of options under the AST LLC Incentive Plan have the right to exercise for AST LLC Incentive Units, which may then be converted into AST LLC Common Units, which may further be converted into shares of the Class A Common Stock.

There were two types of options granted under the AST LLC Incentive Plan: (1) service-based options and (2) performance-based options. Service-based options typically vest over afive year service period with 20% of the award vesting on the first anniversary of the employee’s commencement date, and the balance thereafter in 48 equal monthly installments. Certain service-based options also provide for accelerated vesting if there is a change in control or other performance condition as defined by the AST LLC Incentive Plan. Performance-based options typically vest on the earliest date that any of the following occurs: (i) AST LLC effects an initial public offering and becomes a reporting company, (ii) AST LLC experiences a change of control, or (iii) other specified performance conditions. Both service-based and performance-based options typically expire no later than 10 years from the date of grant.

SpaceMobile 2020 Incentive Award Plan

In connection with the Business Combination, the Company adopted the 2020 Incentive Award Plan (the “2020 Plan”). Awards may be made under the 2020 Plan covering an aggregate number of Class A Common Stock shares equal to 10,800,000. Any shares distributed pursuant to an award may consist, in whole or in part, of authorized and unissued Common Stock, treasury Common Stock or Common Stock purchased on the open market.

Any shares subject to an award under the 2024 Plan or the 2020 Plan that expires, is forfeited, otherwise terminates or is settled in cash, after the Effective Date, shall be added to the shares reserved for issuance under the 2024 Plan. In addition, the number of shares available for issuance under the 2024 Plan may increase on each January 1st occurring following the Effective Date in an amount up to 2,000,000 shares by action of the Company’s Board of Directors or its committee as applicable. On each December 4, 2024 and December 30, 2025 in accordance with the evergreen feature, effective January 1, 2025 and January 1, 2026, respectively, an additional 2,000,000 shares of Common Stock were authorized by the Company’s Board of Directors to be issued under the 2024 Plan.

As of December 31, 2025, the Company had not issued any awards under the ESPP.

Income Taxes

The Company, organized as a C corporation, owns an equity interest in AST LLC in what is commonly referred to as an “Up-C” structure. For U.S. federal and state income tax purposes, AST LLC has elected to be treated as a partnership and does not pay any income taxes since its income and losses are included in the returns of the members. The portion of the Company’s taxable income or loss attributable to the noncontrolling interests of AST LLC is taxed directly to such members. Consequently, no provision for income taxes has been included in the financial statements related to this portion of taxable income. Certain foreign wholly-owned entities are taxed as corporations in the jurisdictions in which they operate, and accruals for such taxes are included in the consolidated financial statements. The Company has operations in India, the United Kingdom (“U.K.”), Spain and Israel with tax filings in each foreign jurisdiction.

The components of income (loss) before income taxes were as follows (in thousands):

The income tax expense was as follows (in thousands):

The differences between the effective income tax rate and the statutory U.S. federal income tax rate for the year ended December 31, 2025 are as follows (dollars in thousands):

(1)

State taxes in California and Massachusetts make up the majority (greater than 50 percent) of the tax effect in this category.

The differences between the effective income tax rate and the statutory U.S. federal income tax rate for years ended December 31, 2024 and 2023 are as follows:

Income taxes paid for the year ended December 31, 2025 are as follows (in thousands):

Deferred Tax Assets and Liabilities

Deferred income taxes reflect the net tax effects of tax carryovers and temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the balances for income tax purposes. Significant components of deferred tax assets and liabilities are as follows (in thousands):

As of December 31, 2025 the Company had unused federal net operating loss carryforwards (gross) for federal income tax purposes of approxim ately $503.2 million, which can be carried forward indefinitely and may be used to offset future taxable income. In addition, the Company had unused net operating loss carryforwards (gross) for state income tax purposes of approximately $164.0 million, $93.9 million of which expire in 2041 to 2045. The remaining $70.1 millionnet operating loss carryforwards (gross) for state income tax can be carried forward indefinitely. The Company also had unused net operating loss carryforwards (gross) for foreign income tax purposes of approximately $4.5 million, which can be carried forward indefinitely.

Management assesses the need for a valuation allowance in each tax paying component or jurisdiction based upon the available positive and negative evidence to estimate whether sufficient taxable income will exist to permit realization of the deferred tax assets. On the basis of this evaluation, as of December 31, 2025 and 2024 the Company's valuation allowance was $618.4 million and $212.1 million, respectively. The change from December 31, 2024 to December 31, 2025 was primarily driven by the basis difference in the equity of AST LLC, an increase in the net operating loss carryforward in the U.S. jurisdiction, and an increase in the state blended rate. The change from December 31, 2023 to December 31, 2024 was primarily driven by the basis difference in the equity of AST LLC and an increase in the net operating loss carryforward in the U.S. jurisdiction. As of December 31, 2025, the Company had deferred tax assets in Germany, Israel, and Spain of $4.2 million and as of December 31, 2024, the Company had deferred tax assets in Germany, Israel, Spain, and the U.K. of $1.6 million. No valuation allowance was recorded against these deferred tax assets, as it was more likely than not that they would be fully realized. As of December 31, 2025, the U.K. was in a net deferred tax liability position of $14.9 million and therefore, no valuation allowance was recorded in that jurisdiction. The foreign deferred tax asset is subject to foreign exchange risk, which could reduce the amount the Company may ultimately realize. Additionally, future changes in tax laws or interpretations of such tax laws may limit the Company’s ability to fully utilize the foreign net operating loss carryforwards.

Unrecognized Tax Benefits

There wereno unrecognized tax benefits andno amounts accrued for interest and penalties as of December 31, 2025. The Company is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its position.

Tax Receivable Agreement

In connection with the closing of the Business Combination, the Company entered into the Tax Receivable Agreement (the “Tax Receivable Agreement”). Pursuant to the Tax Receivable Agreement, the Company is generally required to pay the TRA Holders (as defined in the Tax Receivable Agreement)85.0% of the amount of savings, if any, in U.S. federal, state, local, and foreign taxes that are based on, or measured with respect to, net income or profits, and any interest related thereto that the Company and any applicable consolidated, unitary, or combined Subsidiaries (the “Tax Group”) realize, or are deemed to realize, as a result of certain “Tax Attributes,” which include:

•

existing tax basis in certain assets of AST LLC and certain of its direct or indirect Subsidiaries, including assets that will eventually be subject to depreciation or amortization, once placed in service, attributable to AST LLC Common Units acquired by the Company from a TRA Holder (including AST LLC Common Units held by a Blocker Corporation acquired by us in a Reorganization Transaction (as defined in the Tax Receivable Agreement)), each as determined at the time of the relevant acquisition;

•

tax basis adjustments resulting from taxable exchanges of AST LLC Common Units (including any such adjustments resulting from certain payments made by us under the Tax Receivable Agreement) acquired by the Company from a TRA Holder pursuant to the terms of the A&R Operating Agreement;

•

tax deductions in respect of portions of certain payments made under the Tax Receivable Agreement; and

•

certain tax attributes of Blocker Corporations holding AST LLC Common Units that are acquired directly or indirectly by the Company pursuant to a Reorganization Transaction.

Some circumstances, such as the Company’s election to terminate early the Tax Receivable Agreement or certain changes of control of the Company or AST LLC (as described in the A&R Operating Agreement), may require the Company to make lump-sum cash payments based on certain assumptions to all the TRA Holders equal to the present value of all forecasted future payments that would have otherwise been made under the Tax Receivable Agreement. Payments under the Tax Receivable Agreement will be the obligations of the Company and not obligations of AST LLC. Any payments made by the Company under the Tax Receivable Agreement will generally reduce the amount of overall cash flow that might have otherwise been available to the Company.

As of December 31, 2025, there have been no Tax Receivable Agreement liabilities recorded.

U.S. federal income tax returns for tax years 2022 and forward remain open to examination. The Company and its subsidiaries are also subject to income tax in multiple state, local and foreign jurisdictions. Substantially all significant state and local income tax returns for the years 2022 and forward are open to examination. Substantially all significant foreign income tax returns for the years 2021 and forward are open to examination.

Net Loss per Share

Basic and diluted net loss per share attributable to the holders of Class A Common Stock is computed by dividing net loss attributable to common stockholders by the weighted-average number of shares of Class A Common Stock outstanding during the period.

The following table sets forth reconciliations of the numerators and denominators used to compute basic and diluted net loss per share of Class A Common Stock (in thousands, except share data):

In accordance with FASB ASC 260, Earnings Per Share, penny warrants are warrants that would be exercised for no or little consideration and therefore should be included in the calculation of weighted average shares outstanding for purposes of calculating basic and diluted net income (loss) per share. The Penny Warrants became exercisable (subject to a lockup until March 22, 2026 which lockup was waived by the Company in February 2026) and are included in basic and diluted net loss per share from June 23, 2025 when the Bankruptcy Court (as defined below) approved the Spectrum Usage Rights Transaction (as defined below) with Ligado, LLC.

At December 31, 2025, the Company excluded from the calculation of diluted net loss per share 11,227,292 shares of Class B Common Stock,78,163,078 shares of Class C Common Stock,122,000 Private Placement Warrants,11,835,421 shares of Class A Common Stock that may be issued pursuant to awards outstanding under the AST LLC Incentive Plan, the 2020 Plan and the 2024 Plan, and 21,772,975 shares of Class A Common Stock issuable upon conversion of the 20324.25% Convertible Notes, the 20322.375% Convertible Notes, and the 20362.00% Convertible Notes (on an as-converted basis) as their effect would have been to reduce the net loss per share. Therefore, the weighted-average number of shares of Class A Common Stock outstanding used to calculate both basic and diluted net loss per share of Class A Common Stock is the same.

Shares of the Company’s Class B and Class C Common Stock do not participate in the earnings or losses of the Company and are therefore not participating securities. As such, separate presentation of basic and diluted loss per share of Class B and Class C Common Stock under the two-class method has not been presented.

Spectrum Usage Rights and Related Financing

On January 5, 2025, AST LLC entered into a binding agreement (the “Strategic Collaboration Term Sheet”) with Ligado LLC under which the Company will receive long-term access to up to 45 MHz of lower mid-band spectrum in the United States and Canada for direct-to-device satellite applications. The Strategic Collaboration Term Sheet was entered into as part of the restructuring of Ligado LLC, which together with certain of its direct and indirect subsidiaries (together with Ligado LLC, “Ligado”) filed voluntary petitions for relief under Chapter 11 of the United States Bankruptcy Code in the United States Bankruptcy Court for the District of Delaware (“Bankruptcy Court”).

On March 22, 2025, pursuant to the Strategic Collaboration Term Sheet, the Company, AST LLC, Spectrum USA I, LLC, a subsidiary of AST LLC (“SpectrumCo”) and Ligado entered into certain definitive agreements that, among other things, provided for (1) a $550.0 million contingent payment from the Company to Ligado, (2) SpectrumCo’s obligation to make spectrum access usage payments of at least $80.0 million annually (“L-band Annual Payment”) (with the option to pay the excess of the amount owed by Ligado to utilize the L-band spectrum in Class A Common Stock of the Company for the first three years), and revenue share payments in exchange for the right to use up to 40 MHz of the L-band spectrum, (3) the Company’s obligation to pay a usage fee amount due in cash (plus a 30% premium with respect to each such payment payable, at the Company’s discretion, in cash or in Class A Common Stock of the Company) (the “Crown Castle Annual Payment”) for the right to use up to 5 MHz of the 1670-1675 MHz spectrum, and (4) issuance of 4,714,226 penny warrants, each of which entitles the holder to purchase one whole share of Class A Common Stock at a price of $0.01 per share (“Penny Warrants”), to Ligado. The Penny Warrants are equity classified and accounted for as non-employee share-based payments under ASC 718, Compensation – Stock Compensation, with a grant date fair value of approximately $121.2 million.

On June 13, 2025, the Company announced a Settlement Term Sheet (the “Term Sheet”) among various parties including the Company, Ligado, Viasat, Inc. and Inmarsat Global Limited (“Inmarsat”). Pursuant to the Term Sheet, as long as Ligado’s Chapter 11 plan is confirmed and as long as the financial sponsors of Ligado provide a backstop commitment to Ligado that is acceptable to the Company, in support of a full refund of payments by Ligado in the event applicable regulatory approvals are not obtained and the closing does not occur (the “Backstop Commitment”), the Company agreed that, with respect to the $550.0 million otherwise owed to Ligado in connection with the Spectrum Usage Rights Transaction, the Company will pay $420.0 million to Ligado for the benefit of Inmarsat on October 31, 2025, $100.0 million to Ligado for the benefit of Inmarsat on March 31, 2026 and $15.0 million to Ligado for the benefit of Inmarsat on receipt of specified regulatory approvals and the closing of the Spectrum Usage Rights Transaction. The remaining $15.0 million would be payable to Ligado at the closing. On June 23, 2025, the Bankruptcy Court approved the transactions (the “Spectrum Usage Rights Transaction”) contemplated in the Strategic Collaboration Term Sheet. On or about September 29, 2025, the Bankruptcy Court confirmed Ligado’s Chapter 11 plan. On October 31, 2025, the Company made the $420.0 million payment to Ligado for the benefit of Inmarsat and presented the $420.0 million payment as capital advances to Ligado within Other non-current assets in the Company’s consolidated balance sheets. The remaining obligations in the Term Sheet constitute an off-balance sheet commitment as of December 31, 2025 whose obligations were not recognized in the consolidated financial statements.

The Backstop Commitment provided by Ligado’s financial sponsors has been memorialized in an amendment to Ligado’s debtor in possession financing arrangements and has been approved by the Bankruptcy Court. The funds under the $520.0 million Backstop Commitment will be available to be drawn by Ligado only in the event the applicable regulatory approvals are not obtained in accordance with the definitive documents between the Company and Ligado, and is subject to the satisfaction of certain other limited conditions. The proceeds of the Backstop Commitment can only be used to refund the Company for the amount that we paid to Ligado for the benefit of Inmarsat prior to receipt of the applicable regulatory approvals.

To support consideration payments in connection with the Ligado Transaction, on July 15, 2025 (the “Credit Facility Closing Date”), SpectrumCo entered into a credit agreement (the “Credit Agreement”) with Sound Point Agency LLC, as administrative agent and collateral agent, and the lenders from time to time party thereto. SpectrumCo has not yet drawn any funds under the Sound Point Credit Agreement. The Sound Point Credit Agreement provides for a non-recourse senior-secured delayed-draw term loan facility (“Sound Point Credit Facility”) in an aggregate principal amount of $550.0 million (“Loan Amount”). Subject to the satisfaction of certain conditions, the Credit Facility will be available to SpectrumCo to draw until October 5, 2026 with an option to extend for an additional 180 days (“Availability Period”) subject to payment of an additional 1% fee on the Loan Amount. The Sound Point Credit Facility will be available to SpectrumCo upon the satisfaction of certain conditions, including, among others, (i) entry into security documents and other related documents, (ii) receipt of all required regulatory and Federal Communications Commission (“FCC”) approvals relating to the Spectrum Usage Rights Transaction, (iii) occurrence of certain bankruptcy-related events pertaining to Ligado and (iv) certain other customary conditions to funding. The Sound Point Credit Facility will be secured by substantially all of the assets of SpectrumCo and the newly formed subsidiary that will purchase and collect the receivables associated with the revenues generated from use of the L-band spectrum (“RevenueCo”). RevenueCo will also act as a guarantor under the Sound Point Credit Facility. SpectrumCo’s assets are not available to satisfy the claims of creditors of the Company or AST LLC. Neither the Company nor AST LLC will be liable as a borrower or guarantor or otherwise for any payments owing in connection with the Sound Point Credit Facility, and the lenders’ recourse to the assets of AST LLC will be limited to AST LLC’s equity interests both in SpectrumCo and in RevenueCo.

The Sound Point Credit Facility required SpectrumCo to pay a commitment fee equal to 2% of the Loan Amount, which SpectrumCo has fully paid. The Sound Point Credit Facility also includes a ticking fee equal to 0.15% of the Loan Amount payable on a monthly basis from the Credit Facility Closing Date to the date the Sound Point Credit Facility is drawn. If SpectrumCo terminates the Sound Point Credit Facility prior to the end of the Availability Period, SpectrumCo will be required to pay a termination fee, payable in cash or shares of the Company’s Class A Common Stock at SpectrumCo’s option, ranging from 1% to 5% of the Loan Amount depending on when SpectrumCo terminates the Sound Point Credit Facility. The Sound Point Credit Facility also requires SpectrumCo to pay an upfront fee equal to 3% of the Loan Amount that will become payable when SpectrumCo draws on the Sound Point Credit Facility (and will act as a reduction to proceeds received) and other fees, which became payable starting from the Credit Facility Closing Date. During the year ended December 31, 2025, the Company recognized $4.0 million for the amortization of the commitment fee within Interest expense in the consolidated statements of operations. The remaining unamortized commitment fee was presented within Other current assets in the consolidated balance sheets.

In addition to the Sound Point Credit Agreement, which has not been drawn under, on October 31, 2025, BackstopCo entered into the UBS Loan Agreement with UBS AG, Stamford Branch, as lender. Refer to Note 7 Debt for details.

As of December 31, 2025, the Company recorded $185.6 million of advanced consideration for the spectrum usage rights asset being acquired by the Company through the Spectrum Usage Rights Transaction within Intangible assets, net in the consolidated balance sheets that consisted of $121.2 million representing the grant date fair value of the Penny Warrants issued to Ligado,

$41.6 million in payments made or accrued towards the L-band Annual Payment and $18.5 million in payments made towards the Crown Castle Annual Payment, and approximately $4.3 million of direct third-party transaction costs. The closing of the Spectrum Usage Rights Transaction is still subject to receipt of satisfactory regulatory approvals required for the proposed use of the spectrum, as well as other closing conditions.

Global S-Band Spectrum Priority Rights Acquisition

On September 25, 2025, the Company acquired 100% of the issued and outstanding equity interests in EllioSat Ltd., whose wholly owned subsidiary, Sky and Space Global (UK) Limited holds certain S-Band ITU priority rights to Mobile Satellite Services frequencies in the range of 1980-2010 MHz and 2170-2200 MHz, for use in LEO (the “Transaction”). The Transaction has a total consideration of $64.5 million, to be paid in stock or cash at the Company’s election, with (i) $26.0 million paid at closing, (ii) $10.0 million to be paid on the second anniversary of closing, and (iii) $10.0 million to be paid on the third anniversary of closing. Additionally, the Company is obligated to pay $16.65 million upon the successful launch and effective in-service of a L/S satellite to be manufactured and $1.85 million upon continuous operation of such L/S satellite for a period of at least 90 days.

The Transaction was accounted for as an asset acquisition. As of December 31, 2025, the Company recorded approximately $59.6 million of indefinite-lived intangible asset related to the ITU priority rights acquisition within Intangible assets, net in the consolidated balance sheets that consisted of the $42.9 million of purchase consideration, approximately $1.8 million of direct third-party transaction costs, and $14.9 million of increase in the intangible asset’s carrying amount due to deferred tax liabilities recognized for the temporary cost and tax bases differences. The $42.9 million of purchase consideration included (i) $26.0 million paid at closing in shares of the Company’s Class A Common Stock, (ii) the present value of $10.0 million to be paid by the Company on the second anniversary of closing, which is presented within Other non-current liabilities in the consolidated balance sheets and (iii) the present value of $10.0 million to be paid by the Company on the third anniversary of closing which is presented within Other non-current liabilities in the consolidated balance sheets. The Company did not recognize the $18.5 million allocated to the acquisition of an operational L/S satellite as the related milestones were not met as of December 31, 2025.

Vodafone Joint Venture

On July 7, 2025, the Company and Vodafone entered into an agreement to create SatCo, a jointly-owned European satellite service business headquartered in Luxembourg, to exclusively distribute the Company’s broadband satellite services to MNOs in European markets. In addition, SatCo is expected to deploy a small network of earth stations that integrate with operators of existing 4G/5G terrestrial networks, providing backhaul links, as well as extended coverage across Europe from the anticipated satellite constellation in LEO. Upon formation of the joint venture, the Company contributed exclusive distribution rights at a determined fair value of approximately $23.5 million, as a non-cash consideration, in return for a $5.9 million equity investment in SatCo and a $17.6 million receivable from SatCo that carries an annual interest of 6.6%. The Company recognized interest income of $0.6 million during the year ended December 31, 2025. Both the equity investment and the accrued balance of the receivable are reported within Other non-current assets in the consolidated balance sheets. The Company accounted for the difference between the fair value of the exclusive distribution rights and its cost basis as non-current contract liabilities which the Company expects to recognize over the exclusivity period commencing with the initiation of commercial services.

SatCo is a variable interest entity of which the Company is not a primary beneficiary, and the Company accounts for its investment using the equity method of accounting.
