Grabar Law Office Investigates AST SpaceMobile Shareholder Claims

Grabar Law Office is investigating potential claims on behalf of long-term shareholders of AST SpaceMobile, Inc. (NASDAQ: ASTS) concerning whether certain officers and directors breached fiduciary duties owed to the company. This investigation follows the filing of a federal securities fraud class action against AST SpaceMobile, Chairman and Chief Executive Officer Abel Avellan, and Chief Financial Officer and Chief Legal Officer Andrew M. Johnson.

The investigation stems from allegations that AST and certain senior executives made materially false or misleading statements or failed to disclose that: - AST's increasing capital requirements were likely to increase the company's debt load and shareholder dilution more frequently and on a greater scale than investors had been led to expect. - AST allegedly overstated the sufficiency of its capital and liquidity position to achieve its strategic and business objectives. - AST allegedly overstated the durability of its competitive position in the satellite direct-to-cellular market. - AST was allegedly experiencing slow user adoption in the United States and Japan. - These circumstances were allegedly likely to negatively affect AST's business and financial prospects.

According to the underlying class action complaint, AST continued making positive statements concerning its liquidity and competitive position while subsequently raising substantial additional capital through multiple convertible-note offerings. In October 2025, AST announced a convertible-note offering ultimately sized at $1.0 billion. Its share price allegedly declined approximately 9.24% following the disclosures. AST announced another $1.0 billion convertible-note offering in February 2026, after which its stock allegedly declined approximately 15.17%. On July 15, 2026, AST announced another $1.0 billion convertible-note offering, with an option for an additional $150 million. AST shares allegedly declined 17.04% the following day, closing at $55.01 per share.

The underlying class action complaint also alleges that Chairman and CEO Abel Avellan sold 55,244 AST shares for more than $5.5 million, while CFO and Chief Legal Officer Andrew M. Johnson sold 190,131 shares for more than $13 million during the alleged Class Period.
