Background of the Investigation
York Space Systems completed its initial public offering in January 2026. 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.
During York’s earnings call, the Company further stated that gross margin was “19%, down 4 percentage points year on year,” driven by EAC adjustments “which were a tailwind last year and a headwind this year.” York 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 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.”
Following these disclosures, York’s stock price declined sharply, falling by as much as approximately 19% intraday on May 15, 2026.
In light of these disclosures, Johnson Fistel is investigating whether York Space Systems complied with state and federal laws, including the federal securities laws.
