SCHEDULE 13D/A

Abel Avellan's beneficial ownership stake in AST SpaceMobile decreased to 22.0% of Class A Common Stock (78,163,078 shares) following the company's issuance of approximately 2 million new shares through a registered direct offering to repurchase convertible notes and an at-the-market equity facility, both completed on October 29, 2025. Avellan made no transactions himself during this period but retains 73.0% voting control through his ownership of all Class C Common Stock, which carries ten votes per share. This is the 15th amendment to his original Schedule 13D filing from March 2022, reflecting the dilution of his percentage stake due to the company's capital raising activities rather than any sale of his holdings.
