Abel Avellan's beneficial ownership stake in AST SpaceMobile decreased from a higher percentage to 24.0% of outstanding Class A Common Stock (78,163,078 shares) due to the company's issuance of new shares through an at-the-market equity offering in May and September 2025, though Avellan himself conducted no stock transactions. Despite the dilution of his Class A holdings, Avellan maintains 75.1% voting control through his ownership of all Class C Common Stock, which carries ten votes per share with no economic rights.
