Is AMTM overvalued in 2026?
Amentum Holdings Inc. (AMTM) currently trades at $21.80 per share with a market capitalization of $5,052,462,000.00. Based on our multi-factor framework, the stock appears richly valued with a Smart Value Score of 49/100. This score blends growth quality, financial health, and price attractiveness into a single institutional-grade read.
The stock trades at a P/E ratio of 34.5x, below its 5-year median of 62.4x.
Looking at its own history, AMTM is currently trading cheaper than 88% of the last 5Y on P/E. This places it in the 13th percentile of its historical range, a level that has historically coincided with attractive entry points.
A standard DCF model does not produce reliable output for AMTM under current conditions. For unprofitable or near-breakeven companies, revenue-based multiples such as EV/Sales and historical P/S percentile are more informative than intrinsic value calculations.
The Piotroski F-Score of 4/9 puts financial quality in a middling range, neither a standout strength nor an obvious red flag.
Bottom line: AMTM appears richly valued on our framework, with a Smart Value Score of 49/100. At current levels the risk/reward is skewed against the buyer. A materially lower price or significant operational improvement would be needed to change the picture.
