Amentum: The Mispriced Architect Of Edge AI And Nuclear Defense
Amentum Holdings rated Strong Buy, driven by transformation into an advanced engineering monopsony controlling key nuclear, defense, and AI infrastructure bottlenecks. AMTM's forward catalysts include Deep Isolation's borehole nuclear waste disposal, integration of CG-SEA software into missile defense, and bridging DoD-grade cybersecurity for hyperscalers. Reaffirmed FY2026 guidance (revenue $13.95–$14.3B, adj. EBITDA $1.1–$1.14B, FCF $525–$575M) and sub-3x net leverage by FY2026 may enable aggressive capital returns.
