The estimated intrinsic value of ONE Gas, Inc. (OGS) using a Dividend Discount Model (DDM) is $89.67 (based on the recommended DDM method), compared to the current stock price of $88.93. This suggests the stock may be undervalued by 0.8% relative to its intrinsic value.

For utility companies, which are valued primarily for their stable and predictable dividend streams, SharesGrow uses a Dividend Discount Model (DDM): Intrinsic Value = Annual Dividend ÷ (Cost of Equity − Dividend Growth Rate). This model assumes a long-term dividend growth rate of 4% — consistent with the historical average for regulated utilities — and uses a minimum 7% cost of equity. The DDM is the preferred valuation method for income-oriented stocks with stable payout histories.

The valuation uses a CAPM-derived discount rate of 4.89% (CAPM-derived from beta of 0.74). For comparison, the standard 20-year DCF model produces: Operating Cash Flow (OCF): $152.24 | Net Income (NI): $39.56.
