AST SpaceMobile (NASDAQ: ASTS) faces a securities fraud class action in the Western District of Texas covering March 4, 2025 to July 15, 2026, alleging it omitted slow U.S. and Japan user adoption and dilution from three separate $1.0 billion convertible note offerings. Shares fell 17.04% to $55.01 on July 16, 2026, the day after the third offering priced. The lead plaintiff deadline is November 13, 2026.
AST SpaceMobile Inc. was hit with a securities fraud class action alleging the satellite-to-phone operator concealed slow subscriber adoption in the U.S. and Japan while raising roughly $3.0 billion through three separate $1.0 billion convertible note offerings.
The complaint, captioned Hunter v. AST SpaceMobile, Inc., No. 26-cv-00378, was filed in the U.S. District Court for the Western District of Texas and covers purchases between March 4, 2025 and July 15, 2026, according to a notice from Kessler Topaz Meltzer & Check LLP. Investors have until November 13, 2026 to seek lead plaintiff status.
"Defendants failed to disclose to investors 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," the complaint alleges, per the KTMC summary. The suit also claims AST overstated the durability of its competitive position in the satellite direct-to-cell market, including after its EchoStar transaction.
The disclosure issue centers on capital structure. The complaint alleges AST overstated the sufficiency of its liquidity to fund its business plan, and that the company was experiencing slow user adoption in both the U.S. and Japan. AST priced $1.0 billion of 1.625% convertible senior notes due 2034 on July 15, 2026 — the third offering of that size in the class period.
Shares fell $11.30, or 17.04%, to close at $55.01 on July 16, 2026, the day after the pricing. The decline followed a January 7, 2026 downgrade to sell from Scotiabank, which cited competition from SpaceX's Starlink, slow customer adoption and satellite launch delays.
The case is one of at least two parallel filings. Schall, Brown & Schwartz LLP issued its own shareholder alert on September 22, 2026, citing the same class period and the same November 13, 2026 deadline, and alleging violations of Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and Rule 10b-5. Neither class has been certified.
For holders, the suit keeps two questions in front of the market: whether AST's subscriber ramp in the U.S. and Japan is tracking toward its stated targets, and whether further convertible issuance is needed to fund its satellite constellation buildout. The next scheduled marker is the November 13, 2026 lead plaintiff deadline; any amended complaint or court ruling on a motion to dismiss would extend the legal overhang beyond that date.
