YSS CLASS ACTION NOTICE: Faruqi & Faruqi, LLP Reminds York Space Systems (YSS) Investors of Securities Class Action Lawsuit Deadline on October 30, 2026

Faruqi & Faruqi, LLP is investigating potential claims against York Space Systems, Inc. (NYSE: YSS) and reminds investors of the October 30, 2026 deadline to seek the role of lead plaintiff in a federal securities class action that has been filed against the Company. The complaint alleges that the Company and its executives violated federal securities laws by making false and/or misleading statements and/or failing to disclose: (1) that York's onboard mission and payload software was not fully functional before satellites were launched; (2) that this ongoing trend presented a risk to the Company's contracts with the SDA; and (3) that, as a result of the foregoing, Defendants' positive statements about the Company's business, operations, and prospects, were materially misleading and/or lacked a reasonable basis. On May 11, 2026, Wolfpack Research published a report entitled "YSS: Lost In Space - The Pentagon Just Killed 96% of York's Revenue," citing multiple former software engineers who stated that York "sent satellites into space without even knowing if the software was fit to accomplish its basic mission," and suspecting that the Pentagon's decision to eliminate Tranche 3 funding was "rooted in severe disappointment in York." On this news, YSS stock price fell approximately $7 during intraday trading on May 11, 2026, on unusually heavy trading volume. The lawsuit alleges York Space Systems misled investors by failing to disclose that its onboard mission and payload software was not fully functional before satellite launches, potentially jeopardizing contracts with the Space Development Agency (SDA). Investors who acquired York securities in connection with its January 2026 IPO and/or purchased or acquired York securities between January 29, 2026 and May 11, 2026 may be eligible to participate.
