Comment for Type of Reporting Person:
(1) The Aggregate Amount Beneficially Owned by Each Reporting Person in Row (11) with Sole Voting Power in Row (7) and Sole Dispositive Power in Row (9) comprised of (i) 89,547 shares of Class A Common Stock of AST SpaceMobile, Inc. (the "Issuer") and (ii) 78,163,078 shares of Class A Common Stock of the Issuer that may be issued upon redemption by the Reporting Person of 78,163,078 common units (the "AST Common Units") of AST & Science, LLC ("AST"). In addition, the Reporting Person beneficially owns 78,163,078 shares of Class C Common Stock of the Issuer (the "Class C Common Stock"). Each share of Class A Common Stock carries one vote per share, and each share of Class C Common Stock carries ten votes per share and no economic rights. From and after April 6, 2022, the Reporting Person may redeem or exchange one AST Common Unit for one share of Class A Common Stock or, under certain circumstances and at the election of the Issuer, a cash payment based on the value of Class A Common Stock. At the time of any redemption or exchange, the Reporting Person would forfeit an equivalent number of shares of Class C Common Stock to the Issuer. As discussed in Item 2 of the Original Filing (as defined herein), the other Stockholder Parties (as defined in the Original Filing) are not included as reporting persons in this Schedule 13D, and the Reporting Persons expressly disclaim beneficial ownership of the shares of Class A Common Stock beneficially held by the other Stockholders Parties. (2) The Percent of
Class Represented by Amount in Row (11) in Row (13) is based upon approximately 376,909,461 shares of Class A Common Stock outstanding comprised of (i) 298,746,383 shares of Class A Common Stock outstanding as of May 7, 2026, and (ii) approximately 78,163,078 shares of Class A Common Stock issuable upon the redemption or exchange of the AST Common Units owned by the Reporting Person. This percentage does not represent the Reporting Person's current voting interest in the Issuer, as the Reporting Person has an 71.6% voting interest in the Issuer by virtue of his ownership of all of the shares of Class C Common Stock of the Issuer. AMENDMENT NO. 18 TO SCHEDULE 13D This Amendment No. 18 to Schedule 13D (this "Amendment No. 18") amends and supplements the initial Schedule 13D filed by Mr. Abel Avellan with the Securities and Exchange Commission (the "SEC") on March 11, 2022 (the "Original Filing"), as amended by Amendment No. 17 to Schedule 13D filed by Mr. Avellan with the SEC on March 3, 2026 ("Amendment No. 17"), as amended by Amendment No. 16 to Schedule 13D filed by Mr. Avellan with the SEC on November 21, 2025 ("Amendment No. 16"), as amended by Amendment No. 15 to Schedule 13D filed by Mr. Avellan with the SEC on October 31, 2025 ("Amendment No. 15"), as amended by Amendment No. 14 to Schedule 13D filed by Mr. Avellan with the SEC on July 15, 2025 ("Amendment No. 14"), as amended by Amendment No. 13 to Schedule 13D filed by Mr. Avellan with the SEC on June 20, 2025 ("Amendment No. 13"), Amendment No. 12 to Schedule 13D filed by Mr. Avellan with the SEC on January 27, 2025 ("Amendment No. 12"), as amended by Amendment No. 11 to Schedule 13D filed by Mr. Avellan with the SEC on November 20, 2024 ("Amendment No. 11"), as amended by Amendment No. 10 to Schedule 13D filed by Mr. Avellan with the SEC on October 15, 2024 ("Amendment No. 10"), as amended by Amendment No. 9 to Schedule 13D filed by Mr. Avellan with the SEC on September 26, 2024 ("Amendment No. 9"), Amendment No. 8 to Schedule 13D filed by Mr. Avellan with the SEC on August 26, 2024 ("Amendment No. 8"), Amendment No. 7 to Schedule 13D filed by Mr. Avellan with the SEC on July 11, 2024 ("Amendment No. 7"), Amendment No. 6 to Schedule 13D filed by Mr. Avellan with the SEC on June 14, 2024 ("Amendment No. 6"), Amendment No. 5 to Schedule 13D filed by Mr. Avellan with the SEC on March 6, 2024 ("Amendment No. 5"), Amendment No. 4 to Schedule 13D filed by Mr. Avellan with the SEC on January 25, 2024 ("Amendment No. 4"), Amendment No. 3 to Schedule 13D filed by Mr. Avellan with the SEC on July 6, 2023 ("Amendment No. 3"), Amendment No. 2 to Schedule 13D filed by Mr. Avellan with the SEC on May 2, 2023 ("Amendment No. 2") and Amendment No. 1 to Schedule 13D filed by Mr. Avellan with the SEC on December 13, 2022 ("Amendment No. 1").

| Item 6. | Contracts, Arrangements, Understandings or Relationships With Respect to Securities of the Issuer |
On June 22, 2026, AA Gables 2 entered into a master confirmation (the "Master Confirmation"), supplemental confirmation (the "Supplemental Confirmation") and pricing notice (the "Pricing Notice") under Rule 144 of the Securities Act of 1933, as amended in respect of a variable prepaid forward transaction (the "Forward Contract") with an unaffiliated dealer covering up to a maximum of 2,500,000 shares of Class A Common Stock (the "Subject Shares"). The Forward Contract obligates AA Gables 2 to deliver to the dealer up to 2,500,000 Subject Shares (or, at AA Gables 2's election, an equivalent amount of cash) on specified dates in March of 2028. The transaction is divided into four components, each comprising up to 625,000 shares of Class A Common Stock (the "Component Shares"). The number of Component Shares (or the equivalent amount of cash if AA Gables 2 elects cash settlement), to be delivered to the dealer on the related settlement date will be based on the volume-weighted average price per share of Class A Common Stock on the related valuation date (the "Settlement Price"). The number of shares of Class A Common Stock (or, in each case, the equivalent amount of cash if AA Gables 2 elects cash settlement), to be delivered to the dealer on the settlement date of each component will be determined as follows: (A) if the Settlement Price is less than or equal to $59.58 (the "Floor Price"), AA Gables 2 will deliver the Component Shares; (B) if the Settlement Price is less than or equal to $111.72 (the "Cap Price"), but greater than the Floor Price, AA Gables 2 will deliver a number of shares of Class A Common Stock equal to (i) the Component Shares, multiplied by a fraction, the numerator of which is the Floor Price and the denominator of which is the Settlement Price; and (C) if the Settlement Price is greater than the Cap Price, AA Gables 2 will deliver a number of shares of Class A Common Stock equal to (i) the Component Shares, multiplied by (ii) a fraction, the numerator of which is the sum of (x) the Floor Price and (y) the Settlement Price minus the Cap Price, and the denominator of which is the Settlement Price. In exchange for assuming this obligation, AA Gables 2 received an upfront aggregate cash payment of approximately $146.7 million. AA Gables 2 has pledged 2,500,000 AST Common Units (the "Pledged Securities") to secure its obligations under the Forward Contract. AA Gables 2 will retain voting rights in the Pledged Securities during the term of the Forward Contract. The foregoing description of the transaction does not purport to be complete and is subject to, and qualified in its entirety by reference to, the Master Confirmation, the Supplemental Confirmation and the Pricing Notice, which are filed as Exhibits 9, 10 and 11 hereto, respectively. In connection with the Forward Contract, also on June 22, 2026, the Issuer, AST and AA Gables 2 entered into an Issuer Agreement which addresses the pledge of the Pledged Securities and certain other obligations and undertakings of the parties thereto in connection with the Forward Contract (the "Issuer Agreement"). The foregoing description of Issuer Agreement does not purport to be complete and is subject to, and qualified in its entirety by the Issuer Agreement which is filed as Exhibit 12 hereto. | |
