Allegations Against AST SpaceMobile and Key Events Cited in the Complaint

According to the press release issued by Robbins LLP, the complaint alleges that AST SpaceMobile, Inc. misled investors regarding its competitive position in the satellite direct-to-cellular ("D2C") market. The filing states that defendants touted AST's "purportedly unique competitive advantages and leadership position" in that market. The complaint further alleges that defendants' representations came into question in September 2025, when EchoStar Corporation announced a definitive agreement with SpaceX to sell its AWS-4 and H-block spectrum licenses, enabling Boost Mobile subscribers to access SpaceX's Starlink Services, LLC D2C service.

The complaint, as described in the Robbins LLP announcement, alleges that defendants failed to disclose seven specific items during the Class Period. These include that AST's capital requirements were likely to increase its debt load and share dilution "with greater frequency and at greater scale" than signaled to investors; that defendants overstated the sufficiency of AST's capital and liquidity position; that defendants overstated the durability of AST's competitive position even after the EchoStar Transaction; and that AST was experiencing slow user adoption in the U.S. and Japan. The complaint states that "as a result, defendants' public statements were materially false and misleading at all relevant times."

The announcement identifies three separate stock price declines between September 8, 2025 and July 15, 2026, each tied to convertible note offerings. The July 15, 2026 offering included capped call transactions at "an initial cap price of $149.20 per share," representing "a premium of 125.0% over the last reported sale price" on that date. Robbins LLP states that it represents investors on a contingency fee basis and that no payment is required to participate in the class action.
