Mercury Systems Rises 1% After Hours as Record Bookings and Backlog Drive Higher FY2027 Outlook

Mercury Systems (NASDAQ: MRCY) shares rose about 1% in after-hours trading after the defense electronics company reported record first-quarter bookings, revenue and adjusted EBITDA and raised its fiscal 2027 outlook.

First-quarter revenue increased 12.4% year over year to approximately $253 million, while bookings surged 48% to $370 million. The strong order intake produced a book-to-bill ratio of 1.46 and pushed backlog to nearly $2.1 billion, up 44.7% from a year earlier.

Profitability also improved sharply. Mercury reported GAAP net income of $13 million, or $0.21 per diluted share, compared with a net loss of $13 million a year earlier. Adjusted EPS doubled to $0.52, while adjusted EBITDA rose 58.6% to $56 million and adjusted EBITDA margin reached 22.3%.

Cash flow remained a weaker point. Operating cash flow was negative $14 million, while free cash flow was negative $24 million, compared with negative $4 million a year earlier. Net debt, however, declined 19% year over year to $232 million.

Mercury said more than $1 billion of its backlog is expected to convert into revenue over the next 12 months. Management also said the stronger first-quarter execution prompted the company to raise its fiscal 2027 outlook.

The modest after-hours gain appears to reflect confidence in accelerating demand, improving margins and a record backlog, partly offset by continued near-term cash outflow.
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.
