Valuation Metrics
Fundamental Analysis
Key Financial Insights: ⢠Low net margin ⢠Negative quarterly FCF ⢠High intangibles AMTM is large but barely profitableâsolid recurring revenue ($14.4B FY) with ~1% net margin, recent negative quarterly FCF, heavy leverage/intangibles, and rich earnings multiples that leave little cushion.
Price Behavior
Key Price Behavior Insights: ⢠Short-term down ⢠Near moving average ⢠Support vulnerability Support Level: $25.17â$25.84 Resistance Level: $30.30 AMTM is in a short-term downtrend after an ~11.5% fall over the last month, sitting ~1.6% below its last-month moving average near $27.47 and trading just under key support around $25.17 (secondary $25.84) with resistance near $30.30âwatch a sustained close back above the moving average (~$27.5) for a bounce or a decisive break below $25.17 to extend the decline.
Sentiment & News
Key News Insights: ⢠Nuclear & defense ⢠Short-term cashflow ⢠Active investors Amentum secured sizable nuclear and defense contracts and expanded operations while facing short-term cash-flow pressure from a government shutdown amid mixed institutional trading, though management reaffirmed 2026 guidance.
AI Summary
Amentum is increasingly a backlogâdriven, higherâmargin engineering platform (nuclear/space/contested logistics) whose valuation hinges on converting its $47B backlog into steady, positive free cash flowâmonitor Q2 collections and the pace of JV capital calls as the primary proof points. If management demonstrably cuts receivables days and reaches net leverage <3x by yearâend, the recovery thesis is validated; repeated negative FCF or major contract timing slips will likely compress multiples and justify continued skepticism.
