SCHEDULE 13D/A

Abel Avellan's beneficial ownership stake in AST SpaceMobile decreased from prior levels to 20.8 percent of Class A Common Stock (78.2 million shares) as of February 27, 2026, due to the company's issuance of approximately 17.7 million new shares through convertible note repurchases, warrant exercises, and an at-the-market equity offering totaling over $296 million. Avellan did not sell any shares; his percentage decline resulted solely from dilution caused by the company's capital-raising activities, though he retains 71.7 percent voting control through his ownership of all Class C Common Stock carrying ten votes per share.
