Amentum Q4 2025 Revenue reached an impressive $3.93 billion, marking a significant 77 percent increase compared to the prior-year period. This strong fourth quarter capped fiscal year 2025, during which the advanced engineering and technology company generated an annual revenue of $14.4 billion, reflecting a 4 percent pro forma increase. The sustained success stemmed from robust, continued demand and consistent yearly growth across its critical Digital Solutions and Global Engineering Solutions segments.
Financial Highlights and Strategic Positioning
The company’s exceptional financial performance exceeded management’s expectations, clearly demonstrating the resilience of its business model and its direct alignment with enduring global trends and the mission-critical priorities of its customers. Amentum’s annual adjusted EBITDA climbed to $1.1 billion, representing a 5 percent increase year-over-year. Management successfully reduced net debt to $3.6 billion and ended the quarter with a strong $47 million backlog, posting a full-year book-to-bill ratio of 1.2. This performance underscores significant long-term revenue visibility.
Looking ahead, CEO John Heller confirmed that Amentum remains well-positioned to capitalize on strong tailwinds in key strategic growth areas, including global nuclear energy, critical digital infrastructure, and space systems and technology.
Major Contract Wins Bolster Backlog
Amentum actively strengthened its backlog during the quarter by securing several high-value, long-term contracts across multiple domains. The company successfully won a 10-year, $4 billion Range contract with the U.S. Space Force. Additionally, Amentum secured a nine-year, $1.8 billion Cosmos contract with NASA, alongside a 15-year, $1.8 billion agreement for nuclear remediation services at Sellafield.
The firm also captured nearly $700 million in intelligence and advanced engineering awards, including developing and delivering AI-enabled software coding capabilities for critical intelligence customers. These wins confirm the company’s strategic dominance in space systems and technologies, global nuclear energy, and advanced engineering services across both government and commercial sectors.
Positioning for Next-Generation Defense
The company also strategically aligns itself for future opportunities such as the Golden Dome program, which its leadership views as a robust growth area. Amentum leverages existing expertise from its work with the Missile Defense Agency and NORAD in crucial areas like digital missile defense, hypersonic satellite detection, and virtual engineering. Furthermore, Amentum actively participates in the $150 billion Scalable Homeland Innovative Enterprise Layered Defense (SHIELD) contract, anticipating task orders to commence in the latter part of fiscal year 2026.
This comprehensive strategy, which combines national security and civilian space experience, ensures Amentum continues to support the government’s national security and commercial objectives across the space domain. The exceptional performance captured in the Amentum Q4 2025 Revenue demonstrates a strong trajectory into the next fiscal year.
