from the latest 10-K, 10-Q and 8-K eventsAmentum Holdings is a global advanced engineering and technology solutions provider formed in 2024 from a merger and spin-off, serving U.S. and allied government agencies.
What they do
Amentum provides full mission lifecycle solutions across energy, environmental, intelligence, space, defense, civilian and commercial markets. It operates in two segments: Digital Solutions (DS) and Global Engineering Solutions (GES). DS focuses on digital and data-driven solutions like intelligence analytics, cybersecurity, and space systems; GES handles large-scale environmental remediation, nuclear power solutions, and platform engineering.
Revenue drivers
- Digital Solutions (DS) — Advanced digital and data-driven solutions including intelligence analytics, space system development, cybersecurity, and next-generation IT; quarterly revenue of $1.46B in Q3 FY2026, up 3% YoY.
- Global Engineering Solutions (GES) — Large-scale environmental remediation, nuclear power solutions, platform engineering, sustainment and supply chain management; quarterly revenue of $2.03B in Q3 FY2026, down 5% YoY.
- U.S. federal government contracts — Approximately 81% of fiscal year 2025 revenues from U.S. federal government contracts, either prime or subcontractor.
Recent performance
In Q3 FY2026 (ended July 3, 2026), revenues were $3.49B, down 2% YoY; net income was $66M, up from $10M; diluted EPS was $0.27; adjusted EBITDA was $290M, up 6% YoY. Operating cash flow was $146M and free cash flow was $135M. Backlog was $48.2B, with a book-to-bill of 1.1x for the quarter and 1.3x for the last twelve months.
Strategy
Management focuses on margin expansion through favorable mix shift and operational performance. They are pursuing new contract wins in critical digital infrastructure and space systems, and have recently announced key wins and partnerships in global nuclear energy. The company also uses acquisitions, joint ventures, and targeted divestitures to sustain growth, and leverages its scale and backlog ($47.1B as of October 3, 2025) to pursue large, complex contracts.
Risks
- U.S. federal government concentration — ~81% of FY2025 revenue from U.S. federal government; significant decreases in spending or contract awards would materially hurt results.
- Budget and appropriations uncertainty — Government shutdowns and continuing resolutions, as experienced in late 2025 and early 2026, can delay contract awards and new program starts.
- Fixed-price contract risk — Cost overruns on fixed-price contracts could reduce profitability, especially in an inflationary or high-interest-rate environment.
- Acquisition integration and impairment risk — The company's strategy relies on acquisitions and divestitures, which carry integration risks and potential goodwill impairment charges.
Outlook
Management increased guidance for Adjusted EBITDA and Adjusted Diluted EPS for FY2026, citing strong year-to-date performance. They note near-term dynamics impacting revenue outlook but view the budget environment as constructive. NASA's increased focus on insourcing and potential federal budget changes are being monitored, though no material impact to date.
