Amentum Attracts $9.99M SEGRA Stake and Executes Artemis II Countdown Test
SEGRA Capital Management established a new $9.99 million stake in Amentum by acquiring 417,025 shares in Q3, representing 4.04% of its 13F assets. Separately, Amentum executed the Countdown Demonstration Test for NASA’s Artemis II program, mobilizing over 300 engineers under its EGS contract.
1. SEGRA Capital’s Strategic $10 Million Stake in Amentum
According to a November 14, 2025 SEC filing, SEGRA Capital Management established a new position in Amentum by acquiring 417,025 shares valued at approximately $9.99 million as of the end of Q3. This allocation represents 11.55% of the firm’s total 13F assets under management and rounds out SEGRA’s portfolio to four reportable positions. The other three major holdings include a $47.01 million position in Ur-Energy, $29.26 million in NexGen Energy and a smaller $195,920 stake in Vistra Energy. SEGRA’s move underscores growing institutional interest in Amentum’s defense and energy services platform.
2. Robust Financial Profile and Backlog Support
Amentum reported trailing twelve-month revenue of $14.39 billion and net income of $66 million through October 3, 2025. The company ended its fiscal year with a contract backlog of $47 billion, reflecting strong demand for mission-critical services. Free cash flow exceeded $500 million last year, enabling the firm to prioritize debt reduction while reinvesting in strategic growth areas such as cyber intelligence and space systems integration.
3. Key Role in Artemis II Countdown Demonstration Test
On December 20, 2025, Amentum deployed over 300 personnel to support NASA’s Countdown Demonstration Test at Kennedy Space Center under the Exploration Ground Systems program. The company provided end-to-end ground systems engineering, including launch vehicle integration, spacecraft processing and Launch Control System software, which enabled real-time data processing and remote command. This effort directly contributes to the upcoming Artemis II mission, slated for no later than April 2026, in which Orion will carry four astronauts around the Moon aboard NASA’s Space Launch System.
4. Recent Stock Rebound and 2026 Outlook
After a 25.21% year-over-year decline as of mid-November 2025, Amentum shares have rebounded by 28% over the past three months and are up nearly 40% year-to-date. The recovery reflects investor confidence in the company’s diversified contract portfolio and the government’s renewed emphasis on defense and nuclear energy infrastructure. With the recent Space Force award of a $4 billion, 10-year contract and ongoing momentum in national security programs, Amentum enters 2026 positioned for sustainable growth and margin expansion.
