Amentum is trading 4.17% down now at $21.58 after investors continued reacting to its August 10 earnings release and lowered fiscal 2026 revenue guidance.

  • Revenue guidance fell to $13.8–$13.95 billion from $13.95–$14.3 billion, citing delayed awards and lower materials volume.
  • Adjusted EPS beat expectations, while profitability guidance increased; stronger margins and backlog growth were overshadowed.
  • Broader markets are higher, making the decline relatively company-specific.
