The Portnoy Law Firm announced a securities class action on behalf of York Space Systems investors who bought between January 29, 2026 and May 11, 2026, with a lead plaintiff motion deadline of October 30, 2026. The claims track a May 11 Wolfpack short report alleging the Pentagon's elimination of the SDA Tranche 3 Transport Layer, a program responsible for the majority of York's annual revenue, and claiming York deceived the agency with false advertising and delivered satellites with incomplete mission-critical software. York completed its IPO of 18.5 million shares at $34.00 on or around January 29, 2026, the first day of the class period.
