SC 13G/A

Citadel entities and Kenneth Griffin collectively held approximately 1.75 million shares of AST SpaceMobile as of December 31, 2021, representing roughly 3.4% of the company's outstanding stock through various holdings including Citadel Equity Fund Ltd., CRBU Holdings LLC, and Citadel Securities. This amended Schedule 13G filing indicates that Citadel's beneficial ownership fell below the 5% threshold, triggering the requirement to report the cessation of majority ownership status as of the filing date in February 2022.
