Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. Summary of Significant Accounting Policies Basis of Presentation and Principles of Consolidation The accompanying unaudited condensed 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 unaudited condensed 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. In the opinion of management, these unaudited condensed consolidated financial statements contain all adjustments (consisting only of normal and recurring adjustments) necessary to fairly state the unaudited condensed consolidated financial statements. 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. The accompanying unaudited condensed consolidated financial statements and related notes should be read in conjunction with the Company’s audited consolidated financial statements and notes thereto as of and for the year ended December 31, 2025, included in its Annual Report on Form 10-K filed with the SEC on March 2, 2026 (the “2025 Annual Report on Form 10-K”). The results of operations for the periods presented are not indicative of the results to be expected for the year ending December 31, 2026 or for any other interim period or other future year. 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 unaudited condensed 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, 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. The Company’s significant accounting policies are described in Note 2 Summary of Significant Accounting Policies of the 2025 Annual Report on Form 10-K, and there have been no significant changes in these significant accounting policies as compared to those described therein. 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 in one 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 unaudited condensed consolidated statements of operations as revenues less total operating expenses and other segment items. Other segment items include loss 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 a portion of the 2032 4.25% Convertible Notes and the 2032 2.375% Convertible Notes and foreign exchange losses for the three months ended March 31, 2026 and 2025, respectively. The measure of segment assets is reported on the accompanying unaudited condensed consolidated balance sheets as total assets. 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 Accounting Standards Codification (“ASC”) 606, Revenue from Contracts with Customers (“ASC 606”). During the three months ended March 31, 2026 and 2025, the Company recognized $13.4 million and $0.4 million of Products revenue from the 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 three months ended March 31, 2026 and 2025, the Company recognized $1.3 million and $0.3 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 the Company 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 March 31, 2026 and December 31, 2025, $233.0 million and $227.0 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 increase in contract liabilities during the three months ended March 31, 2026 was primarily due to advance payments received from MNOs related to gateway equipment sales. There was no revenue recognized for the three months ended March 31, 2026 that was included in the December 31, 2025 contract liability balance. 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 March 31, 2026. The Company expects to recognize approximately 8.4% 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. 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 expedient, available as part of the early adoption of Accounting Standards Update (“ASU”) 2025-05 Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets, 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 March 31, 2026, the majority of outstanding accounts receivable are considered current. For the three months ended March 31, 2026 and 2025, the Company’s customers had high credit ratings and the allowance for credit losses was immaterial. Future Adoption of Recently Issued Accounting Pronouncements In November 2024, the Financial Accounting Standards Board (“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 this ASU on the presentation of its consolidated financial statements. In September 2025, the 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. In December 2025, the FASB issued ASU 2025-10, Government Grants (Topic 832): Accounting for Government Grants Received by Business Entities. The ASU establishes authoritative guidance in GAAP about accounting for government grants received by business entities, clarifies the appropriate accounting, in an effort to reduce diversity in practice, and increase consistency of application across business entities. The ASU is effective for annual reporting periods beginning after December 15, 2028, and interim reporting periods within those annual reporting periods. Adoption of this ASU can be applied using a modified prospective approach, a modified retrospective approach, or a retrospective approach. 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.

Future Adoption of Recently Issued Accounting Pronouncements

In November 2024, the Financial Accounting Standards Board (“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 this ASU on the presentation of its consolidated financial statements.

In September 2025, the 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”).
