Why Mercury Systems Stock Is Sinking Today

Mercury Systems (MRCY) reported Q4 2026 revenue of $289.8M, beating estimates, and set a new quarterly sales record. However, shares fell 6.4% due to missed EPS estimates and margin contraction, with operating margin dropping to 5% from 8.6% YoY. The company's high valuation (70x forward earnings) also raised investor concerns.
