Mercury Systems: Record Bookings and a Palantir Partnership Mark a Turning Point

Mercury Systems: Record Bookings and a Palantir Partnership Mark a Turning Point

Mercury Systems capped fiscal 2026 with a quarter that shattered its own records. The defense electronics maker reported Q4 bookings of $660 million, up 93% year over year, record backlog of $1.9 billion, and record revenue of $290 million. This isn't just a good quarter; it's a validation of the multi-year strategy to transition from a development-heavy portfolio to scaled production. The company also raised its FY27 outlook and provided initial FY28 reference points, signaling confidence in the durability of the demand surge.

CEO Bill Ballhaus opened the call with the headline numbers: “We delivered Q4 results that were ahead of our expectations with record bookings record backlog, record revenue, the highest EBITDA margin of the year, and robust free cash flow.” — William L. Ballhaus, Chairman and Chief Executive Officer · 2026-08-18 More importantly, he noted that the strength was broad-based, not dependent on any single program. “The strength in Q4 bookings was broad based, with significant production awards across our products and solutions in common processing architecture, effectors, airborne applications, space and missile defense. Most notably, we had our largest quarter ever for CPA bookings which we believe reflects the differentiation of our CPA solutions.” — William L. Ballhaus, Chairman and Chief Executive Officer · 2026-08-18 This is a clear departure from prior quarters where growth was more concentrated in a few legacy programs.

Backlog Conversion and the Palantir Catalyst

The quarter also brought a strategic agreement that could change how Mercury executes. “We recently announced a strategic agreement with Palantir to leverage AI software to enhance material planning and factory operations in an effort to improve backlog conversion.” — William L. Ballhaus, Chairman and Chief Executive Officer · 2026-08-18 This is a novel, company-specific move that addresses a long-standing pain point: the company's history of missed delivery schedules and working capital drag from inventory and unbilled receivables. The partnership is designed to pull supply chain data forward, reducing the “bathtub” effect where material arrives late and capacity sits idle.

The company has been talking about improving backlog conversion for several quarters. In the prior Q3 call, Ballhaus said: “you've seen over the last several quarters that we've been successful in accelerating deliveries, and it's had an impact in us delivering results that ahead of our expectations.” — William L. Ballhaus, Chairman and Chief Executive Officer · 2026-02-03 But the Palantir deal takes this from a manual effort to an AI-driven process. CFO Dave Farnsworth added in the current call that they expect CapEx to be flat while they lean into supply chain: “we feel like we have got capacity to lean a little into our supply base. And be able to bring in material earlier so that we can reduce what is the normal lead time.” — David Farnsworth, Executive Vice President and CFO · 2026-08-18 This is a shift in working capital strategy that could drive the 35% FCF conversion they've guided for FY27.

CPA and the Path to Margin Expansion

The common processing architecture (CPA) business is emerging as the growth engine. The company's largest quarter ever for CPA bookings reflects its differentiation, particularly in secure processing. Ballhaus also highlighted a new frontier: “We are now starting to see some customer interest in the smaller form factor … that opens up a whole new additional TAM in terms of smaller form factors that could fit on different platforms.” — David Farnsworth, Executive Vice President and CFO · 2026-08-18 This is a fresh expansion vector, building on the broad based demand they're already seeing. The margin profile of new bookings is also improving, supporting the bridge to the low-to-mid-20s EBITDA target. The gross margin for FY26 was 28.6%, up 70bps year over year, and management expects this to continue as lower-margin legacy backlog burns off.

The international business was a rare soft spot, with revenue down ~15% due to a contract manufacturing transition. However, Ballhaus characterized it as temporary: “over the last year, we have outsourced our manufacturing in our international business to a contract manufacturer. And we have seen a slowdown in deliveries as we have ramped up that contract manufacturer.” — William L. Ballhaus, Chairman and Chief Executive Officer · 2026-08-18 He expects this to resolve over the next couple quarters, leaving domestic (85.8% of revenue) as the key growth driver.

Outlook: Raised Targets and Tailwinds

Looking forward, Mercury raised its organic growth target to low double digits, with FY27 revenue approaching $1.1 billion (up ~10%) and adjusted EBITDA approaching $200 million. The company also provided FY28 reference points: low double-digit growth, EBITDA margin at the low end of the target, and FCF conversion back to 50%. Crucially, none of this includes the potential tailwinds from increased defense budgets, Golden Dome, or the Palantir partnership itself. As Ballhaus put it:

Although this outlook for FY 2027 and FY 2028 incorporates a limited set of tailwinds that have materialized in firm bookings, it does not incorporate the benefit of potential additional tailwinds that could occur on a number of production programs across our portfolio.

The market has taken notice. The stock is up ~15% over the past 90 days, though still 27% below its July peak. That drawdown reflects years of underdelivery; this quarter's Record bookings and the Palantir deal suggest the company is finally executing on its potential. With backlog conversion improving and a fresh record revenue backdrop, Mercury looks positioned to re-rate as it delivers on its raised guidance. The path to the low-20s EBITDA margin is now tangible, and the market is starting to buy it.
