York Space Systems is trading 6.3% down at $10.22, pressured after its August 13, 2026 earnings report cut full-year revenue guidance to $375–$405 million from a prior midpoint near $570 million.

  • The reduction reflects delayed government procurement and supply-chain timing, shifting expected revenue into 2027.
  • A new U.S. Space Force NITE-STAR selection was announced August 18, 2026, but has not offset the guidance overhang.
  • Broader technology weakness is adding pressure.
