Amentum Holdings, Inc. (AMTM)
Summary
Amentum: Margin Quality Over Revenue Quantity
Amentum Holdings is deeply undervalued, trading at 7.41x forward P/E versus sector medians near 19x, despite transformative infrastructure moves. AMTM is shifting from legacy government services to high-margin equity-participating roles in nuclear, AUKUS defense, and edge AI data centers, unlocking significant multiple expansion potential. Cutting low-margin NASA contracts and pivoting to firm-fixed-price, technology-driven work positions AMTM for mid-to-high single-digit EBITDA margins and robust FCF deployment.
Amentum: Everyone, And I Mean (Almost) Everyone, Is Wrong About The Stock
Amentum is rated Hold (C+), with upside limited by declining revenue and guidance credibility concerns. Despite record margins, EPS, and backlog, AMTM cut revenue guidance for the second straight quarter, highlighting persistent top-line headwinds. Valuation appears reasonable at an 8.8x forward P/E and 10.5% free cash flow yield, but leverage and lack of a dividend temper the bull case.
