ONE Gas (OGS) Pulls Back On Valuation Questions, Is The Stock Still Cheap?

ONE Gas (OGS) has drawn investor attention after recent share performance showed a modest decline over the past month, prompting fresh questions about how the regulated utility’s fundamentals compare with the current valuation.

Over the past year, ONE Gas has offered a steadier ride than the recent pullback suggests. The 1-year total shareholder return of 5.43% contrasts with the 1-month share price decline of 4.49%, which points to fading near term momentum as investors reassess risk and valuation around the current US$77.34 level.

Scan the wider utilities space alongside ONE Gas by comparing its recent pullback and returns with a curated group of 11 resilient stocks with low risk scores.

The share price reset at around US$77 has shaken off some optimism around ONE Gas. Does that clear room for more upside, or suggest most of the easy gains are already in the rearview before valuation work even begins?

Most Popular Narrative: 14% Undervalued

ONE Gas is trading at $77.34 against a widely followed fair value estimate of about $90.22, which frames the recent pullback as a move that may have stretched the discount rather than closed it.

Favorable regulatory developments, particularly Texas House Bill 4384, enable full recovery of capital expenditures and reduce regulatory lag. This is anticipated to support higher earnings and more predictable net profit margins in the coming years. Accelerating capital investment in system reinforcement and modernization (such as the Austin system project), in response to both safety and demand, expands the regulated rate base and results in higher allowed returns and EPS growth.

See why 0 investors see ONE Gas as 14% undervalued.

Result: Fair Value of $90.22 (UNDERVALUED)

Still, the ONE Gas story only holds if regulators continue to support cost recovery, and if rising capital and operating expenses do not squeeze future profitability.
