Mercury Systems Stock Falls 9% Premarket Despite Record Bookings as Q4 Profit and Cash Flow Weaken
Mercury Systems (NASDAQ: MRCY) shares are down about 9% in premarket trading Wednesday after the defense technology company reported fiscal fourth-quarter 2026 results. While bookings, backlog and revenue reached records, weaker earnings and cash-flow metrics appear to be overshadowing the strong demand picture.
Record Defense Demand Drives Backlog Higher
Mercury reported Q4 revenue of $290 million, up 6.1% year-over-year and a quarterly record. More importantly, bookings surged 93.1% to a record $660 million, producing a strong book-to-bill ratio of 2.28.
The surge in orders pushed backlog above $1.9 billion, up 38.4% from a year earlier. Approximately $1.0 billion of that backlog is expected to convert into revenue over the next 12 months, providing considerable revenue visibility entering fiscal 2027.
The figures point to strong underlying demand for Mercury's aerospace and defense technologies, consistent with elevated spending and modernization activity across the defense sector.
Earnings Decline Despite Revenue Growth
The weaker part of the report was profitability. Q4 GAAP net income fell sharply to just $1 million, or $0.01 per share, from $16 million, or $0.27 per share, a year earlier.
Adjusted EPS also declined to $0.37 from $0.47, while adjusted EBITDA slipped to $49 million from $51 million despite higher revenue. The 16.7% adjusted EBITDA margin was Mercury's highest of fiscal 2026, but the year-over-year earnings deterioration may have disappointed investors given the company's improving sales trajectory.
Cash generation also weakened on a full-year basis. Fiscal 2026 free cash flow declined to $68 million from $119 million, while operating cash flow fell to $102 million from $139 million.
Strong Backlog Versus Near-Term Profitability
For the full year, revenue increased to $984 million from $912 million, while bookings reached $1.5 billion and adjusted EBITDA improved to $150 million from $119 million. Adjusted EPS swung to a profit of $1.06 from a loss of $0.64 in fiscal 2025.
The 9% premarket decline therefore appears less related to demand and more to the gap between Mercury's record operating momentum and its current earnings conversion. Investors may be focusing on the sharp Q4 decline in GAAP and adjusted EPS, slightly lower quarterly EBITDA, and weaker annual free cash flow.
With a $1.9 billion-plus backlog and a 2.28 quarterly book-to-bill ratio, Mercury enters fiscal 2027 with substantial demand visibility. The key question is whether the company can translate that unusually strong order pipeline into faster earnings and cash-flow growth.
