Using an unlevered Free Cash Flow to Firm (FCFF) model, we project ONE Gas, Inc.'s cash flows over 5 years with line-by-line expense modeling. Revenue is projected revenue growing from 3.4% to 3.9% 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 72, DIO 66). At a 5.9% WACC with mid-year discounting, the terminal value (85% 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 $246.63 per share, suggesting OGS is undervalued by 190.5% at the current price of $84.91.
Adjust parameters to explore scenarios. Changes are for exploration only and do not affect saved valuations.

Using the PEG framework with analyst consensus forward EPS growth of 10.7% plus 3.0% dividend yield, the company has a fair value of $51.76 based on NTM EPS (FY2026) of $4.85. The current PEG ratio is 1.64.
PEG < 1 = bargain, 1–1.5 = fair, > 2 = expensive.
PEG tends to undervalue slow growers — consider dividend yield and asset value instead.
