In April 2026, the Space Force Spring 2026 budget restructured the Transport Layer program and halted Tranche 3 payments.

Eligibility is based on purchase date and documented losses, not on whether you still hold the shares.<\/p>\n<p>\n        <strong>Q: What specific misstatements does the YSS lawsuit allege?<\/strong> A: The complaint alleges York Space Systems Inc. made materially false or misleading statements regarding the functionality and readiness of its satellite software and the maturity of its purportedly modular platform during the Class Period. When reports disclosed that mission-critical software was allegedly incomplete at launch and that Tranche 3 Transport Layer funding had been halted, the stock price declined sharply.<\/p>\n<p>\n        <strong>Q: What court was the YSS class action filed in?<\/strong> A: The case was filed in the United States District Court for the District of Colorado, governed by the Private Securities Litigation Reform Act of 1995.<\/p>\n<p>\n        <strong>Q: What do YSS investors need to do right now?<\/strong> A: Investors may gather brokerage records showing purchase dates, share quantities, and prices paid. <a href=\"https:\/\/www.globenewswire.com\/Tracker?data=kiYYPi12Xrb-_EfPOGAH6h9w9xLPGDl6VIbffsIaKU4EIBdtGBhJx3zqNYOIN0td248XHb1fypc7FKRp_cH63UWzdgz20pTlZMmQ1_nw-EBRuWyTdsLhDkq8LEWYD-P5_vrchI5QbXNw69U5hkaZZ81RapXsYM_NGW7C1-lWHfHnzuwPqfluek7iXdgVCa3zHn76QuvmvUVuL6BN58V0Wd4GW3bCZ-yhbEzpwZVRuOMiqs2C3TN9toEyLUcK7iiK9EIA-sr38VQ1VBGbmmLdlQ==\" rel=\"nofollow\" target=\"_blank\">Submit your information for a no-cost, no-obligation evaluation of your potential recovery<\/a>. No immediate action is required to remain eligible as an absent class member.<\/p>\n<p>\n        <strong>Q: What documents do I need to submit my information?<\/strong> A: Brokerage statements or trade confirmations showing purchase dates, share quantities, prices paid, and any subsequent sale dates and prices.<\/p>\n<p>\n        <strong>Q: What if I already sold my YSS shares, can I still recover losses?<\/strong> A: Yes. Eligibility is based on when you purchased, not whether you still hold the shares. Investors who bought during the Class Period and sold at a loss may still be eligible to participate.<\/p>\n<p>\n        <strong>Q: What does it cost me to participate?<\/strong> A: There is no upfront cost to submit your information and review whether you may be eligible to recover.
