Recent share performance and business overview

Amentum Holdings (AMTM) has attracted investor attention after recent share performance data showed a 3.6% move over the past day, set against weaker returns over the past month and the past 3 months.

At the latest share price of US$26.08, Amentum Holdings shows a 3.6% 1 day share price return, but weaker 30 day and year to date share price returns. The 1 year total shareholder return of 45.9% points to earlier optimism that now appears to be cooling.

With AMTM trading at US$26.08 against a higher analyst price target and an indicated intrinsic discount, the key question is whether the recent pullback leaves shares undervalued or whether the market already reflects future growth.

Most Popular Narrative: 22% Undervalued

At a last close of $26.08 against a narrative fair value of $33.45, Amentum Holdings is framed as materially undervalued, with the story anchored in large, long duration contracts and earnings potential rather than recent share price softness.

Ramp up of large, long duration awards such as the U.S. Space Force Range contract, Sellafield remediation and NASA Cosmos is set to convert the current $47 billion backlog and $20 billion of pending bids into higher run rate revenues and improved operating leverage, supporting sustained earnings growth.

Curious what turns that huge backlog into a higher fair value per share? The narrative leans heavily on rising margins, faster earnings growth and a lower future earnings multiple to make the numbers work.

Result: Fair Value of $33.45 (UNDERVALUED)

However, this upbeat story can falter if large U.S. government contracts face funding delays or if cost overruns on complex projects squeeze already thin margins.

Another way to look at value

The narrative fair value suggests Amentum looks undervalued, but the current P/E of 64.9x tells a different story. It sits well above the 19x industry average, the 16.3x peer average, and even the 35.2x fair ratio, which points to meaningful valuation risk if sentiment shifts.
