The law firm of Kirby McInerney LLP is investigating potential claims against York Space Systems Inc. (“York Space Systems” or the “Company”) (NYSE:YSS). The investigation concerns whether the Company and/or members of its senior management may have violated federal securities laws or engaged in other unlawful business practices.
York Space Systems completed its initial public offering (“IPO”) in January 2026, selling 18,500,00 shares of stock at a price of $34 per share. In connection with the IPO, York described itself as a space and defense company with scalable satellite manufacturing capabilities, including the ability to deliver mission-critical spacecraft “at scale, faster, and at lower cost.” The Company also emphasized its high-rate manufacturing capabilities, revenue visibility, and expected margin growth.
On May 14, 2026, during York Space Station’s first quarter 2026 earnings call, the Company further stated that gross margin was “19%, down 4 percentage points year on year,” driven by estimate at completion (“EAC”) adjustments “which were a tailwind last year and a headwind this year.” EAC is an accounting projection used to estimate the total anticipated costs and labor hours required to finish a long-term contract or manufacturing run. The Company also stated that “the first quarter EAC change, it was negative,” and that the issue would “increase a little bit of material cost and a little bit of labor cost” for the Company. York Space Systems further acknowledged that the EAC change accounted for “about 1 point of the 4 points of margin decline year-over-year.” The Company also discussed timing issues affecting revenue, stating that “a little bit of our 2Q revenue that we were planning to hit in 2Q will just be delayed into 3Q, likely 3Q, potentially some of that into 4Q.” On this news, the price of York Space Systems shares declined by $4.92 per share, or approximately 17%, from $28.94 per share on May 14, 2026 to close at $24.02 on May 15, 2026.
