Amentum has delivered a strong performance for both the fourth quarter and the full fiscal year 2025, exceeding management's expectations. Key highlights include substantial revenue growth (72% GAAP, 4% pro forma), a significant increase in GAAP net income (180%), and robust Adjusted EBITDA growth (5% pro forma). The company has effectively reduced its net debt to $3.6 billion and net leverage to 3.2x, indicating improved financial health. Amentum's backlog stands at an impressive $47 billion, reflecting strong future revenue visibility, supported by a healthy 1.2x book-to-bill ratio for the full year and major contract wins in critical sectors like Space Force and nuclear decommissioning. The positive fiscal year 2026 guidance, projecting continued growth in revenues, Adjusted EBITDA, Adjusted Diluted EPS, and Free Cash Flow, further reinforces a positive outlook. While GAAP diluted EPS saw a quarterly decline, the overall trend across adjusted metrics and strategic wins points to a company with strong momentum in high-growth, mission-critical markets. This combination of strong current performance, strategic positioning, and optimistic future guidance makes Amentum an attractive investment.
