Equity [Abstract] |
Stockholders’ Equity | 10. Stockholders’ Equity Class A Common Stock As of December 31, 2025, there were 285,449,911 shares of Class A Common Stock issued and outstanding. Holders of Class A Common Stock are entitled to one vote for each share. The Company is authorized to issue 800,000,000 shares of Class A Common Stock with a par value of $0.0001 per share. Class B Common Stock As of December 31, 2025, there were 11,227,292 s hares of Class B Common Stock issued and outstanding. Shares of Class B Common Stock were issued to then existing equity holders of AST LLC (other than Mr. Abel Avellan, the Company’s Chairman and Chief Executive Officer (“Mr. Avellan”)) at the time of the Business Combination and are non-economic, but entitle the holder to one vote per share. The Company is authorized to issue 200,000,000 shares of Class B Common Stock with a par value of $0.0001 per share. 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. During the year ended December 31, 2025, there were no such redemptions. Class C Common Stock As of December 31, 2025, there were 78,163,078 shares of Class C Common Stock issued and outstanding. 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 125,000,000 shares of Class C Common Stock with a par value of $0.0001 per share. Mr. Avellan owns 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 any AST LLC Common Units held by Mr. Avellan, a corresponding number of shares of Class C Common Stock held by Mr. Avellan will be cancelled. Correspondingly, the Super-Voting Rights associated with such shares of Class C Common Stock will be terminated. Preferred Stock As of December 31, 2025, there were no shares of preferred stock issued or outstanding. 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 2032 4.25% 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.

As part of the Antares Transactions, Invesat exercised 319,033 AST Incentive Equity Options and 9,932,541 shares of the Company’s Class B Common Stock and 200,000 shares of the Company’s Class A Common Stock previously held by Invesat were cancelled.
