Using an unlevered Free Cash Flow to Firm (FCFF) model, we project Amentum Holdings, Inc.'s cash flows over 5 years with line-by-line expense modeling. Revenue is projected revenue growing from -1.9% to 4.1% annually, with expenses (COGS, SG&A, R&D) held at historical ratios. Depreciation is computed from a vintage matrix based on a 5-year useful life. Working capital is modeled using historical turnover days (DSO 72, DPO 26, DIO 60). At a 7.6% WACC with mid-year discounting, the terminal value (98% of enterprise value) is derived from the Gordon Growth Model on Year 6 FCFF at a 2.5% perpetual rate. After subtracting net debt, the equity value implies a fair price of $20.56 per share, suggesting AMTM is fairly valued by 14.1% at the current price of $23.95.
Adjust parameters to explore scenarios. Changes are for exploration only and do not affect saved valuations.

Using an unlevered Free Cash Flow to Firm (FCFF) model, we project Amentum Holdings, Inc.'s cash flows over 10 years with analyst estimates for the first 3–5 years, fading toward long-term GDP growth for the remaining years with line-by-line expense modeling. Revenue is projected revenue growing from -1.9% to 7.4% annually, with expenses (COGS, SG&A, R&D) held at historical ratios. Depreciation is computed from a vintage matrix based on a 5-year useful life. Working capital is modeled using historical turnover days (DSO 72, DPO 26, DIO 60). At a 7.6% WACC with mid-year discounting, the terminal value (91% of enterprise value) is derived from the Gordon Growth Model on Year 11 FCFF at a 2.5% perpetual rate. After subtracting net debt, the equity value implies a fair price of $28.24 per share, suggesting AMTM is undervalued by 17.9% at the current price of $23.95.
