Robbins Geller Rudman & Dowd LLP announced that investors in York Space Systems Inc. (NYSE: YSS) have until October 30, 2026, to seek appointment as lead plaintiff in a securities class action pending in the U.S. District Court for the District of Colorado. Captioned Ianelli v. York Space Systems Inc., No. 26-cv-04074, the case concerns common stock issued in or traceable to York Space’s January 2026 initial public offering and securities purchased between January 29 and May 11, 2026, inclusive. The complaint names York Space, certain current and former executives, incoming directors and IPO underwriters, alleging violations of the Securities Act of 1933 and the Securities Exchange Act of 1934. It alleges that York Space sold approximately 18.5 million IPO shares at $34 each while failing to disclose that its onboard mission and payload software was not fully functional before satellite launches, creating risks for contracts with the Pentagon’s Space Development Agency. The allegations followed a May 11 report by Wolfpack Research, after which York Space shares fell 10.9%, or $3.91, from $35.88 to $31.97 between May 11 and May 12. Bleichmar Fonti & Auld LLP had previously announced the filing of the same action.
