Kahn Swick & Foti, LLC (“KSF”) and KSF partner, former Attorney General of Louisiana, Charles C. Foti, Jr., notifies investors in York Space Systems, Inc. (“York Space Systems” or the “Company”) (NYSE: YSS) of a class action securities lawsuit.

The lawsuit seeks to recover losses on behalf of investors who purchased or otherwise acquired York Space Systems common stock pursuant and/or traceable to the registration statement and prospectus (collectively, the “Registration Statement”) issued in connection with the Company’s January 2026 initial public offering (“IPO” or the “Offering”); and/or (b) securities between January 29, 2026 and May 11, 2026, inclusive (the “Class Period”).

According to the Complaint, Defendants made materially false and/or misleading statements, as well as failed to disclose material adverse facts about the Company’s business, operations, and prospects.

Specifically, the lawsuit alleges that Defendants failed to disclose to investors that: (i) the Company’s onboard mission and payload software was not fully functional before satellites were launched; (ii) this ongoing trend presented a risk to the Company’s contracts with the Pentagon’s Space Development Agency (“SDA”) deceived the SDA with false advertising to win its contracts, cut corners, and delivered satellites whose mission-critical-software was not completed; 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.

If you invested in York Space and suffered a loss during the relevant time frame, you have until October 30, 2026 to request that the Court appoint you as lead plaintiff; however, your ability to share in any recovery does not require that you serve as a lead plaintiff. York Space Systems investors should contact KSF Managing Partner Lewis Kahn toll-free at (877) 515-1850 or via email (lewis.kahn@ksfcounsel.com), or fill out the form on this page.

The case is Ianelli v. York Space Systems, Inc. et al., 26-cv-04074.
