Mercury Systems Signals Turnaround With Record Bookings

Mercury Systems ((MRCY)) has held its Q3 earnings call. Read on for the main highlights of the call.

Mercury Systems’ latest earnings call struck a cautiously upbeat tone, with management underscoring record bookings, a swelling backlog and sharply better margins. Executives framed the quarter as proof that the turnaround is gaining traction, even as they acknowledged lingering GAAP losses, cash flow volatility and the work still needed to hit long‑term margin ambitions.

Record Bookings and Backlog Momentum

Mercury reported Q3 bookings of $348.3 million, delivering a robust book‑to‑bill of 1.48 and pushing trailing‑12‑month bookings to a record $1.23 billion. Backlog is now approaching $1.6 billion, up about $240 million or 17.9% year over year, giving the company multi‑year revenue visibility and a solid base for future growth.

Double‑Digit Organic Revenue Growth

Revenue for the quarter came in at roughly $235.8 million, translating into 11.5% organic growth versus a year ago. The U.S. market was the standout, with domestic revenue, which represents 88% of the total, rising 17% year over year as defense customers continued to step up spending.

Margin Expansion and Adjusted Profit Upswing

Profitability showed meaningful improvement as adjusted EBITDA rose to about $36.1 million, up 46.2% year over year and yielding a 15.3% margin, an expansion of roughly 360 basis points. Gross margin climbed to 29.3%, about 230 basis points better than last year, while adjusted EPS surged to $0.27 from just $0.06.

Better GAAP Results and Leaner Cost Base

On a GAAP basis the company still posted a loss, but it narrowed significantly to roughly $3 million, or $0.04 per share, from about $19 million, or $0.33, a year earlier. Operating expenses fell around $11 million, or 14.3%, as restructuring, SG&A and R&D outlays were pared back without derailing growth.

Balance Sheet Strength and Working Capital Gains

Mercury ended the quarter with $332 million in cash and equivalents, up about $62 million, or 23%, from a year ago, against net debt of $259.7 million. Year‑to‑date free cash flow stands at $39.5 million, and net working capital has improved, down 4.1% year over year and roughly $225 million, or 34%, from its peak in Q1 FY24.

Operational Execution and Capacity Expansion

Management highlighted accelerated program execution that pulled forward around $25 million of revenue, $15 million of adjusted EBITDA and $25 million of cash that had been slated for Q4. To support ramping production, the company added 50,000 square feet of automated factory space in Phoenix and acquired a provider of critical manufacturing process technology.

Diversified Demand Across the Portfolio

Bookings strength was broad‑based, driven by follow‑on production orders in missiles, C4I and space programs rather than a single blockbuster contract. Leadership emphasized that no individual program accounts for more than roughly 10% of the business, with about 300 programs contributing, which reduces concentration risk and smooths revenue.

Free Cash Flow Volatility in Q3

Despite the strong operational showing, free cash flow in Q3 was a small outflow in the range of $1.8 million to $2 million compared with a $24 million inflow a year earlier. The company had anticipated an outflow and partially mitigated it via better collections, but the result underscored the lumpiness that still accompanies its working capital profile.

Inventory Build and Higher Reserves

Inventory rose sequentially by about $12 million, largely in work‑in‑process as the company ramps production to meet demand. Management also booked roughly $3 million in higher inventory reserves, which partially offset the otherwise strong gross margin gains and signals ongoing cleanup of legacy positions.

Receivable Timing and Unbilled Balances

Billed receivables declined around $10 million and unbilled receivables fell about $4 million, but timing effects continue to complicate the picture. Older unbilled balances remain to be worked down even as new unbilled amounts are created by fresh production ramps, leaving some friction in converting revenue to cash.

GAAP Loss Underscores Work Still Ahead

The narrowed but still negative GAAP net income shows that Mercury’s turnaround is incomplete despite impressive adjusted metrics. Management pointed to ongoing investments and the costs of scaling production as reasons margins have not yet reached levels required for consistent GAAP profitability.

Macro Tailwinds Not Yet in the Numbers

Executives cited several potential demand catalysts, including higher defense budgets and international program opportunities, as upside that is not yet embedded in current bookings. These factors, along with possible accelerations in key defense systems, represent optionality rather than baseline assumptions, leaving room for positive surprise.

Gap to Long‑Term Margin Targets

While the margin trajectory is moving in the right direction, current guidance for the next couple of years still falls short of long‑term goals. Management reiterated its aim for adjusted EBITDA margins in the low‑ to mid‑20% range but conceded that, with FY26 modeled only in the mid‑teens, there remains meaningful work to close the gap.

Outlook and Upgraded Guidance

Mercury raised its FY26 outlook, now expecting annual revenue growth approaching mid‑single digits instead of low‑single digits and adjusted EBITDA margins in the mid‑teens. The company also projected positive free cash flow in Q4 and for the year, tying the stronger guidance to improved backlog conversion, better material staging and potential upside from robust Q4 bookings and defense tailwinds.

Mercury Systems’ call painted a picture of a defense electronics supplier that is steadily regaining its footing, with record bookings, healthier margins and a stronger balance sheet leading the narrative. Investors still must weigh the remaining GAAP losses, cash flow noise and execution risk against the upgraded outlook and sizable backlog, but the trend line is clearly moving in a more constructive direction.
