Mercury Systems (MRCY) Stock Forecast & Price Target

Mercury System is attractive because FY26 showed a broad-based turnaround: revenue rose 7.9% to $984 million, adjusted EBITDA increased 26% to $150 million, book-to-bill exceeded 1.5x, and backlog reached a record $1.9 billion, signaling stronger demand and much better execution. Its Common Processing Architecture is shifting the company from lower-value components toward reusable, trusted processing architectures, which should raise content per platform, increase switching costs, and support margin expansion as higher-margin production programs displace legacy work. The outlook is further reinforced by deep alignment with priority defense themes such as missile defense, electronic warfare, tactical-edge computing, and trusted microelectronics, plus strong revenue visibility with about $1.0 billion of backlog expected to convert within 12 months.

Mercury System is facing a fragile turnaround because growth still appears to trail the DCF’s roughly 15% long-term assumption, while a forward P/E above 50x and a still-GAAP-loss-making profile leave little room for execution errors. Operationally, the company’s history of acquisition-driven complexity has already produced quality issues, delivery delays, margin pressure, and now a slowdown in international deliveries tied to ramping a new contract manufacturer, reinforcing that manufacturing risk remains central. In addition, heavy dependence on U.S. defense spending, concentration in RTX, Lockheed Martin, and Northrop Grumman, and free cash flow conversion below the 50% target near term all weaken visibility and make the valuation vulnerable to any budget or backlog disappointment.
