Why Was AST Sued?

Plaintiff alleges that defendants touted AST's purportedly unique competitive advantages and leadership position in the satellite direct-to-cellular ("D2C") market. Defendants' assurances regarding AST's purportedly durable competitive position in the satellite D2C market came into question in September 2025, when EchoStar Corporation ("EchoStar") announced that it had entered into a definitive agreement with SpaceX to sell its AWS-4 and H-block spectrum licenses (the "EchoStar Transaction"). In connection with the EchoStar Transaction, SpaceX and EchoStar agreed to enter into a long-term commercial agreement, enabling EchoStar's Boost Mobile subscribers—through its cloud-native 5G core—to access SpaceX's next generation D2C service provided by its telecommunications subsidiary Starlink Services, LLC.

Following the EchoStar Transaction, however, defendants continued to assure investors and the market that AST remained in a competitive class of its own, with the Company poised to realize significant revenues and profits in the near-term. Likewise, defendants continuously represented that AST's capital and liquidity position was sufficient to meet its strategic and business goals at all relevant times, notwithstanding the heightened competitive pressures it faced following the EchoStar Transaction.

According to the complaint, during the Class Period, defendants failed to disclose that:

• AST's increasing capital requirements were likely to increase the Company's debt load and share dilution with greater frequency and at greater scale than defendants had signaled to investors;
• accordingly, defendants had overstated the sufficiency of AST's capital and liquidity position to achieve its strategic and business goals;
• defendants likewise overstated the durability of AST's competitive position in the satellite D2C market;
• even following the EchoStar Transaction, defendants continued overstating AST's competitive position in the satellite D2C market;
• AST was experiencing slow user adoption in the U.S. and Japan;
• the foregoing was likely to have a significant negative impact on the Company's business and financial prospects; and
• as a result, defendants' public statements were materially false and misleading at all relevant times.

Why Did AST's Stock Drop?

Between September 8, 2025 and July 15, 2026, a series of stock downgrades and company disclosures caused AST's stock to fall significantly.

Specifically, on October 21, 2025, AST announced "its intent to offer . . . $850.0 million aggregate principal amount of convertible senior notes due 2036 (the 'Notes') in a private offering", and that it "intends to grant the initial purchasers of the Notes . . . an option to purchase . . . up to an additional $150.0 million aggregate principal amount of Notes." AST was to use the proceeds from this offering "for general corporate purposes, including without limitation funding the deployment of AST SpaceMobile's worldwide constellation of satellites in anticipation of adding incremental strategic markets for its SpaceMobile Service." Later the same day, AST increased the offering to $1.0 billion. On this news, AST's Class A common stock price fell $7.26 per share, or 9.24%, to close at $71.35 per share on October 22, 2025.

On February 11, 2026, AST announced its "intent to offer . . . $1.0 billion aggregate principal amount of convertible senior notes due 2036 (the 'Notes') in a private offering", and that it "intends to grant the initial purchasers of the Notes . . . an option to purchase . . . up to an additional $150.0 million aggregate principal amount of Notes." The next day, AST announced the pricing of the foregoing offering at "an initial conversion price of approximately $116.30 per share of AST SpaceMobile's Class A common stock, which represents a premium of approximately 20% to the last reported sale price of AST SpaceMobile's Class A common stock on February 11, 2026." Following these disclosures, AST's Class A common stock price fell $14.70 per share, or 15.17%, to close at $82.22 per share on February 12, 2026.

Finally, on July 15, 2026, AST announced "its intent to offer" another "$1.0 billion aggregate principal amount of convertible senior notes due 2034 (the 'Notes') in a private offering", and that it "intends to grant the initial purchasers of the Notes . . . an option to purchase . . . up to an additional $150 million aggregate principal amount of Notes." Later the same day, AST announced the pricing of the foregoing offering. Specifically, "$1.0 billion 1.625% convertible senior notes due 2034 . . . [at] an initial conversion price of approximately $79.57 per share of AST SpaceMobile's Class A common stock, which represents a premium of approximately 20.0% over the last reported sale price of AST SpaceMobile's Class A common stock on July 15, 2026", as well as "[c]apped call transactions . . . [at] an initial cap price of $149.20 per share of AST SpaceMobile's Class A common stock, which represents a premium of 125.0% over the last reported sale price of AST SpaceMobile's Class A common stock on July 15, 2026." Following these disclosures, AST's Class A common stock price fell $11.30 per share, or 17.04%, to close at $55.01 per share on July 16, 2026.
