SCHEDULE 13D/A

Abel Avellan, founder and controlling shareholder of AST SpaceMobile with a 21.9% Class A stake and 72.9% voting control through Class C shares, amended his forward contract on November 19, 2025 with an unaffiliated dealer covering up to 2.5 million Class A shares with new settlement dates in March 2027 and adjusted floor and cap prices of $56.06 and $79.66 respectively. In connection with this amendment, Avellan's entity AA Gables received approximately $10.7 million in cash, adding to the $42 million in upfront proceeds from the original forward contract. The amendment represents a refinancing of the forward contract terms but does not change the number of shares covered or pledged securities.
