Analysis
Mercury closed fiscal 2026 with a record demand quarter. Fourth-quarter bookings were $660 million, up 93.1% year-over-year, and the 2.28 book-to-bill ratio lifted backlog to over $1.9 billion, up 38.4% year-over-year. The company reported that $1.0 billion of this backlog is expected to be recognized as revenue within the next 12 months, providing the clearest documented indicator of near-term revenue visibility.
Fourth-quarter revenue was a record $289,782 (in thousands), compared with $273,106 (in thousands) a year earlier. Gross margin was $88,583 (in thousands), while income from operations was $14,465 (in thousands), below $23,550 (in thousands) in the prior-year quarter. Selling, general and administrative expense increased to $47,848 (in thousands) from $37,714 (in thousands), and the company recorded $9,319 (in thousands) of stock-based compensation in that expense line versus $653 (in thousands) a year earlier.
Profitability was mixed across reported bases. GAAP net income was $798 (in thousands), or $0.01 per diluted share, versus $16,370 (in thousands), or $0.27 per diluted share, in the prior-year quarter. Adjusted EBITDA was $48,518 (in thousands), compared with $51,269 (in thousands), while adjusted EPS was $0.37 compared with $0.47. For fiscal 2026, adjusted EBITDA rose to $150,192 (in thousands) from $119,438 (in thousands), and adjusted EPS was $1.06, although the company recorded a GAAP net loss of $(29,673) (in thousands) for the year.
Cash generation improved year over year in the fourth quarter, with operating cash flow of $42,153 (in thousands) versus $38,075 (in thousands), but free cash flow was $28,565 (in thousands) versus $33,977 (in thousands) as property and equipment purchases rose to $13,588 (in thousands). For the full year, operating cash flow and free cash flow were below fiscal 2025. Cash and cash equivalents ended at $214,306 (in thousands), while long-term debt was $441,500 (in thousands), after $150,000 (in thousands) of payments under credit facilities and $(15,001) (in thousands) of payments for retirement of common stock.
Management said it is increasing its outlook for organic growth, but the release contains no quantitative fiscal-2027 guidance. The operating focus is therefore the conversion of elevated backlog into revenue, preservation of the reported 16.7% adjusted EBITDA margin, and improvement in GAAP earnings and annual free cash flow. The company also identified execution, quality, supply chain, customer funding, manufacturing capacity, and fixed-price program risks as factors that could affect future results.
