Mercury Systems (MRCY) Stock Forecast & Price Target

Mercury System is poised to benefit from a durable turnaround that is already visible in the numbers: 1Q27 revenue rose 12.4% year over year to $253.2 million, adjusted EBITDA jumped to $56.4 million, and margin expanded about 625 bps despite the company previously signaling no expansion. Its bookings strength remains exceptional, with a 1Q record $370.5 million in bookings, a 1.46x book-to-bill, and backlog up 45% year over year to $2.06 billion, giving management room to raise FY27 revenue growth guidance to double-digits while keeping EBITDA margins in the high-teens. Beyond the near-term beat, the company’s Common Processing Architecture, trusted microelectronics accreditations, and exposure to missile defense, radar, and electronic warfare support a richer mix of higher-value production work, better cash conversion, and a more durable strategic position with defense primes and the U.S. government.

Mercury System is vulnerable because its turnaround thesis depends on flawless manufacturing execution, yet management has already flagged international delivery slowdowns tied to a new contract manufacturer, echoing the quality and delivery breakdowns that damaged results in 2021–22. The business also faces weak cash conversion as FY27 guidance still calls for inventory, automation, and factory optimization spending that should keep free cash flow conversion below the 50% target near term, while a still-GAAP-loss-making profile leaves little margin for error. On top of that, revenue is highly exposed to U.S. defense budgets and customer concentration, with RTX, Lockheed Martin, and Northrop Grumman representing about 36% of FY26 revenue, so any funding delay or program slip could quickly pressure growth and valuation.
