Approach 1: Amentum Holdings Discounted Cash Flow (DCF) Analysis

The Discounted Cash Flow (DCF) model estimates a company’s intrinsic value by forecasting its future free cash flows and discounting them back to today’s value. This approach provides a clearer picture of what a business is truly worth, apart from market sentiment and short-term fluctuations.

For Amentum Holdings, the current Free Cash Flow stands at $139.5 million. Analyst estimates suggest substantial growth over the next several years, projecting Free Cash Flow to reach $654 million by 2027. Looking further, Simply Wall St extrapolates that, by 2035, annual Free Cash Flow could top $921.7 million as the business matures and expands in its sector.

These projections are all expressed in US dollars and use a two-stage Free Cash Flow to Equity model. After applying the DCF technique, the intrinsic value per share is calculated to be $53.41. This figure implies the stock trades at a discount of 54.4 percent to its estimated fair value, suggesting it may be significantly undervalued at current prices.

Result: UNDERVALUED

Our Discounted Cash Flow (DCF) analysis suggests Amentum Holdings is undervalued by 54.4%. Track this in your watchlist or portfolio, or discover 919 more undervalued stocks based on cash flows.

Approach 2: Amentum Holdings Price vs Earnings

The price-to-earnings (PE) ratio is one of the most reliable valuation metrics for profitable companies, as it relates a company’s current share price to its annual net earnings. PE is especially useful in assessing whether investors are paying the right price for a firm’s growth and profitability.

Growth expectations and risk play a critical role in what constitutes a “normal” or “fair” PE ratio. A fast-growing firm often deserves a higher PE, reflecting optimism about future earnings. Conversely, high risks or slower growth typically justify lower multiples.

Amentum Holdings currently trades at a PE ratio of 114.08x. This is significantly higher than both the professional services industry average of 23.69x and the peer average of 23.17x. This wide gap can raise questions about whether the stock’s price already factors in optimistic growth forecasts.

To get a clearer picture, Simply Wall St calculates a proprietary "Fair Ratio" by factoring in key elements like future earnings growth, profit margins, industry nuances, market cap, and risk. This makes the Fair Ratio, here at 41.75x, a more holistic benchmark than simply comparing to peers or industry averages.

With Amentum Holdings’ actual PE of 114.08x sitting well above its Fair Ratio of 41.75x, the shares appear substantially overvalued by this method.

Result: OVERVALUED

Upgrade Your Decision Making: Choose your Amentum Holdings Narrative

Earlier we mentioned there is an even better way to understand valuation, so let's introduce you to Narratives. A Narrative is a simple, powerful idea: it connects your own story and reasoning about a company with concrete numbers, like your estimate for fair value and assumptions about future revenue, earnings, and margins.

Unlike static metrics, Narratives help you translate your vision for a company into an actionable financial forecast, so you can see how its story links directly to a calculated fair value. On Simply Wall St's Community page, millions of investors use Narratives as an accessible tool to map out their investment thesis, whether they expect aggressive growth or see warning signs ahead.

Narratives let you compare your fair value to the current price, helping you decide when to buy or sell, and they automatically update as new information like news or earnings is released. For Amentum Holdings, for example, one investor’s Narrative might see a fair value far above today’s price due to expected contract wins, while another may anticipate challenges and set a much lower fair value. This shows just how perspectives can differ.
