Using an unlevered Free Cash Flow to Firm (FCFF) model, we project Montauk Renewables, Inc.'s cash flows over 5 years with line-by-line expense modeling. Revenue is projected revenue growing from 19.3% to 1.2% 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 28, DPO 31, DIO 60). At a 5.3% WACC with mid-year discounting, the terminal value (90% 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 $12.14 per share, suggesting MNTK is undervalued by 812.6% at the current price of $1.33.

Using an unlevered Free Cash Flow to Firm (FCFF) model, we project Montauk Renewables, 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 19.3% to 3.2% annually, with expenses (COGS, SG&A, R&D) held at historical ratios.
