Amentum Executes Artemis II Countdown Demonstration Test with Over 300 Personnel
Amentum provided ground systems engineering and launch vehicle integration support for NASA’s Artemis II Countdown Demonstration Test at Kennedy Space Center, mobilizing over 300 personnel December 20. Under the Exploration Ground Systems program, Amentum will integrate ground equipment and launch control systems for the Orion-SLS mission launching April 2026.
1. SEGRA Capital’s Strategic $10 Million Investment
SEGRA Capital Management, LLC reported a new position of 417,025 Amentum shares in its Nov. 14 filing with the SEC, representing an investment valued at $9.99 million by the end of Q3 2025. This marks the first time the energy‐focused fund has added Amentum to its portfolio, indicating confidence in the company’s differentiated service model and growth trajectory in government and commercial technical contracts.
2. Portfolio Allocation and Fund Dynamics
The Amentum stake accounts for 11.55% of SEGRA’s 13F assets under management, making it one of four reportable holdings alongside positions in Ur‐Energy and NexGen Energy. While SEGRA’s assets under management have been reduced significantly this year, the firm’s decision to allocate over 4% of its remaining AUM to Amentum underscores the fund’s view of strong near-term catalysts and resilience in a defense and energy contracting specialist.
3. Robust Financial Profile and Backlog Strength
Amentum ended the trailing twelve months with $14.39 billion in revenue and $66 million in net income, generating over $500 million in free cash flow. The company concludes its fiscal year with a backlog of approximately $47 billion, driven by long-term government contracts. Management is deploying cash flow to reduce leverage while selectively investing in technology and capability expansion, supporting margin improvement and contract capture.
4. High-Impact Contract Awards and Growth Drivers
In late 2025, Amentum secured a ten-year, $4 billion award from the United States Space Force under its Exploration Ground Systems program and delivered end-to-end ground systems engineering for the Artemis II Countdown Demonstration Test at Kennedy Space Center. These wins exemplify the company’s expertise in mission-critical systems integration, positioning it to benefit from increased U.S. defense spending, nuclear energy initiatives, and space exploration commitments in 2026 and beyond.
