Executive summary

Amentum Q3 FY26 — Strong Profitability and Cash Flow Despite Revenue Headwinds

Amentum delivered strong profitability and cash generation in Q3 FY26, exceeding expectations for adjusted EBITDA and EPS, driven by margin expansion and operational performance. While near-term revenue faced headwinds from protest periods and procurement delays, the company maintains confidence in its long-term trajectory, underpinned by robust business development momentum in nuclear energy and critical digital infrastructure, and a disciplined capital allocation strategy.

Highlights

5
  • Adjusted EBITDA reached $290 million, up 6% year-over-year, with record margins of 8.3%.

  • Adjusted diluted EPS increased 20% year-over-year to $0.67.

  • Net bookings of $3.9 billion resulted in a quarterly book-to-bill of 1.1x and a trailing 12-month book-to-bill of 1.3x.

  • Funded backlog increased 10% year-over-year to $6.2 billion.

  • Net leverage reduced to 3x at quarter end, one quarter earlier than expected.

Concerns

3
  • Q3 revenue of $3.5 billion came in slightly below expectations, reflecting normalized growth of approximately 1%.

  • FY26 revenue guidance was revised down to $13.8 billion - $13.95 billion due to reduced contributions from new business awards under protest and lower material/non-labor volume.

  • FY27 revenue is expected to be impacted by a 3% reduction from NASA's workforce directive and a 1% reduction from exiting low-margin programs.

Risks & headwinds

NASA Workforce Directive FY27

3% revenue impact in FY27

Mitigation:Focus on mitigating revenue impact with strong program execution and growing margin-accretive areas; impact to adjusted EBITDA expected to be less than revenue due to margin profile of affected contracts.

New Business Delays (Protests & Procurement) FY26

Roughly $175M impact on FY26 revenue

Mitigation:Management expects these dynamics to work out over the next year; continued focus on business development momentum and organic growth.

Low-Margin Program Exits FY27

1% revenue impact in FY27

Mitigation:Intentional decision to exit low-margin domestic-based operations to reallocate resources to higher-return opportunities, expected to be accretive to overall margins.

Government Shutdown Impact Q1 FY26

Impacted Q1 FY26 performance

Mitigation:Adjusted for in normalized growth calculations; Q4 FY26 growth expected to be consistent with year-to-date performance excluding this impact.

Why it matters

This is a significant headwind to FY27 revenue, and any further changes could materially impact the outlook.

Based on conversations with our customers at NASA in recent weeks and months, we now anticipate 3% impact to revenue in fiscal year '27.

Q&A highlights

How does Amentum plan to deploy capital in the next fiscal year, given the achievement of deleveraging targets?

Amentum is pleased with achieving 3x net leverage a quarter early and is preparing for broader capital deployment. Options include M&A, share repurchases, and continued debt reduction, with decisions based on maximizing long-term shareholder value and considering stock valuation. Organic growth opportunities in nuclear and digital infrastructure mean transformational M&A is not required.

“As you can imagine, we've been preparing in recent months to be ready as our capital opportunities broaden for deployment. And that obviously includes working internally and with our Board on the various strategic options, including M&A, share repurchases and continued debt reduction.”

Detailed narrative

Q3 Performance and Strategic Progress

Amentum reported Q3 FY26 revenue of $3.5 billion, reflecting 1% normalized growth, slightly below expectations. However, strong operating performance led to higher-than-anticipated profitability, with adjusted EBITDA of $290 million (8.3% margin) and adjusted diluted EPS of $0.67, up 20% year-over-year.

The company generated $135 million in free cash flow and reduced net leverage to 3x, one quarter ahead of schedule. Strategic progress includes continued business development momentum, particularly in nuclear energy and critical digital infrastructure.

Business Development Momentum

The company achieved net bookings of $3.9 billion, resulting in a quarterly book-to-bill of 1.1x and a trailing 12-month book-to-bill of 1.3x. Ending backlog reached $48 billion, with funded backlog increasing 10% year-over-year to $6.2 billion. Pending awards stand at $32 billion, with two-thirds representing new business.

Amentum is on track to exceed its full-year submits target of $35 billion, with over half being new business. Notable awards include over $400 million in commercial nuclear, $250 million in critical digital infrastructure, and over $1 billion in National Security.

Nuclear Energy Strategy and Key Wins

Amentum's nuclear revenue totals $2 billion, with $0.5 billion in the accelerating Global Nuclear Energy market. The company is the global delivery partner for Rolls-Royce SMR deployments in Sweden, the U.K., and Czech Republic. A strategic partnership with Westinghouse was announced to support the APX platform.

Amentum was also selected by the Department of Energy to lead a consortium for an AI data center and multi-gigawatt nuclear facility at the Savannah River Site, an opportunity expected to exceed $1 billion in revenue over its life and offer economic interest in commercial operations.

Critical Digital Infrastructure Growth

The company is seeing accelerating progress in critical digital infrastructure, including key wins supporting hyperscaler data center build-outs and commercial network infrastructure. Management is incrementally biasing resources towards this area, making strategic hires to bolster business development and project leadership.

The market is receptive to Amentum's integrated engineering and systems integration solutions, which optimize schedules and minimize delivery risks for complex facilities, positioning the company for continued scaling.

Capital Allocation and Deleveraging

Amentum achieved its net leverage target of 3x a quarter early, enabling more flexible and opportunistic capital deployment. The company is evaluating strategic options including M&A, share repurchases, and continued debt reduction, with a focus on maximizing free cash flow per share and long-term shareholder value.

Management emphasized that organic investments and business development success in higher-margin growth areas mean transformational M&A is not required, though it remains a potential part of the strategy.

NASA Workforce Directive Impact

The NASA workforce directive, which aims to insource certain industry-provided services, is now expected to have a 3% impact on FY27 revenue, higher than the previously estimated 1%. This revised estimate is based on detailed discussions with NASA. Due to the margin profile of the affected contracts, the impact on adjusted EBITDA is expected to be less than on revenue, making it accretive to overall margins.

Amentum remains a trusted NASA partner, with larger contracts and IDIQ mechanisms offering future growth opportunities.

Portfolio Shaping and Margin Expansion

Amentum is undergoing organic portfolio shaping, shifting towards higher-margin opportunities. This includes a move from lower-margin managed services to technology-enabled work, and an increase in fixed-price and T&M contracts over cost-plus. The company also made an intentional decision to exit a few low-to-no-margin domestic-based operations, representing approximately 1% of FY27 revenue, to reallocate resources to higher-return opportunities.

This strategy is expected to drive sustained margin improvement in the coming years.
