York Space Systems Inc. reported second quarter 2026 revenue of $92.5 million, up 10% year over year, driven by major government programs. Gross profit rose to $22.2 million with gross margin improving to 24% from 11%, helped by the absence of a prior negative adjustment.
Despite stronger top-line and margin performance, York recorded a net loss of $39.3 million for the quarter and $154.2 million for the first half, with higher operating expenses, including substantial stock-based compensation and transaction costs. Adjusted EBITDA was a loss of $9.5 million in the quarter and $13.1 million year to date.

Liquidity totaled $684 million, including $534 million of cash. The company lowered its 2026 revenue outlook to $375–$405 million, citing a shift in U.S. government acquisition methods, while pointing to eight contract wins at an 88% win rate and recent acquisitions (ALL.SPACE and Solestial) as drivers for expected growth beyond 2026.
