ROSEN, TRUSTED INVESTOR COUNSEL, Encourages York Space Systems Inc. Investors to Secure Counsel Before Important Deadline in Securities Class Action – YSS

A securities class action lawsuit has been filed against York Space Systems Inc. (NYSE: YSS) alleging that the company made materially false and misleading statements regarding its satellite software functionality. The lawsuit claims York Space's onboard mission and payload software was not fully functional before launch, deceived the Pentagon's Space Development Agency with false advertising, and delivered satellites with incomplete mission-critical software. Investors who purchased YSS securities during the class period (January 29, 2026 - May 11, 2026) or through the IPO registration statement are encouraged to join the class action before the October 30, 2026 lead plaintiff deadline.
