Is Amentum Holdings, Inc. overvalued or undervalued?

As of 17 October 2025, the valuation grade for Amentum Holdings, Inc. has moved from fair to attractive, indicating a positive shift in its valuation outlook. The company appears to be undervalued given its current price of $22.40, especially when considering its 52-week range of $16.01 to $34.47. Key valuation ratios such as the price-to-earnings (PE) ratio and enterprise value to EBITDA (EV/EBITDA) are not available for comparison, but the lack of qualifying peers suggests a unique position within the Aerospace & Defense industry.
In terms of performance, Amentum has underperformed against the S&P 500 over the past year, returning -24.55% compared to the index's 14.08%. However, the year-to-date return of 6.51% indicates some recovery potential. Overall, the lack of peer comparisons and the recent grade change suggest that Amentum Holdings, Inc. may represent an attractive investment opportunity despite its recent stock performance.
