ONE Gas: Undervalued Regulated Utility With $97.06 Intrinsic Target and Expanding Dividend Moat

The value investor's first task is to separate the noise of daily trading from the underlying business. Right now, the market's mood for ONE Gas appears overly optimistic. The stock has climbed nearly 21% year to date, a strong run that has lifted the share price to $83.87. Yet, when we look past the recent momentum to the company's intrinsic worth, a different picture emerges.

Using a discounted cash flow model, the calculated intrinsic value for ONE Gas stands at $97.06. This implies the stock is trading at a 14% undervaluation to its estimated true worth. For a disciplined investor, this gap represents a potential margin of safety-a buffer against error and volatility. It suggests Mr. Market's recent enthusiasm may have outpaced the company's fundamental trajectory, at least according to this valuation framework.

Management's recent guidance provides a forward-looking signal that supports the long-term compounding story. The company has set its 2026 non-GAAP earnings per share target between $4.83 and $4.95. This outlook, delivered alongside a steady dividend increase, points to meaningful growth ahead. The current price, however, appears to have already priced in a significant portion of that expected earnings expansion. The setup now hinges on whether the market's forward-looking optimism is justified by the company's ability to execute and grow earnings at the guided pace, or if the current valuation leaves little room for error.

The Business: A Regulated Moat and Capital Discipline

For a value investor, the most important question is not the stock price today, but the durability of the business generating the cash. ONE Gas operates in a classic utility model, built on a wide and durable moat. The company is a 100% regulated natural gas distribution utility, a structure that provides a fundamental advantage. Its revenue stream is exceptionally stable, with more than 92% of the customers served by the company are from the residential category. This high concentration of homes, which rely on gas for heating and cooking, creates predictable demand and strong visibility into future earnings. It is the kind of business that compounds through economic cycles, not just growth spurts.

This stability, however, comes with a capital-intensive nature. The company must continuously invest to maintain its infrastructure and extend its reach. In 2025, it plans to spend $750 million on capital expenditures, a figure that includes pipeline integrity, replacements, and system capacity increases. This disciplined reinvestment is not a cost but a necessary condition for maintaining its regulated monopoly and customer service quality. The scale of this commitment underscores the business's asset-heavy model, where the value is in the network itself.

A key strategic advantage lies in its supply assets. ONE Gas's infrastructure is positioned in close proximity to gas reserves. This geographic alignment translates directly into lower transportation, storage, and commodity costs. In a business where input costs can swing with the market, this built-in cost advantage provides a margin of safety and enhances profitability. It is a structural feature that new entrants cannot easily replicate, further fortifying the competitive moat.

The bottom line is a business designed for long-term compounding. Its regulated status and residential customer base provide a predictable earnings engine. Its capital discipline ensures the engine remains reliable. And its strategic asset positioning offers a cost edge. This is the foundation upon which intrinsic value is built.

Financial Health and the Dividend Moat

The sustainability of a dividend is the ultimate test of a utility's financial health. For ONE Gas, the foundation is solid. The company recently increased its quarterly payout by a penny to $0.68 per share, resulting in an annualized dividend of $2.72. This translates to a forward dividend yield of 3.24%, a figure that is attractive for a regulated utility and signals management's confidence in its cash-generating ability.

That confidence is rooted in a history of consistent earnings. In 2025, the company delivered adjusted earnings per share of $4.48. This performance provides a clear earnings base to support the current payout. More importantly, the forward view is constructive. Management's 2026 guidance calls for non-GAAP earnings per share between $4.83 and $4.95. This projected growth, combined with the already-elevated 2025 earnings, suggests the dividend is well-covered and has room to grow further.

The market's valuation of this stability is reasonable. With a trailing P/E ratio of 19.19 and a forward P/E based on 2026 guidance, the stock trades at a multiple appropriate for a regulated utility. This multiple reflects the premium placed on predictable cash flows and a durable business model. For a value investor, this is the hallmark of a quality compounder: a business that can consistently generate earnings to fund both reinvestment and shareholder returns.

The bottom line is a company with a strong financial moat. Its regulated status and residential customer base provide the earnings stability needed to support a growing dividend. The recent capital discipline and forward guidance reinforce that this isn't a one-time payout but a feature of the long-term business model. In this light, the dividend is not just a return of capital; it is a visible manifestation of the company's intrinsic value being realized.

Catalysts, Risks, and What to Watch

For the value investor, the thesis now turns to execution and catalysts. The path to realizing intrinsic value hinges on a few key events and disciplined operational performance. The most direct near-term catalysts are the pending rate cases in Oklahoma, Kansas, and Texas. These regulatory proceedings, once approved, will provide a formal mechanism to boost annual revenues and support the earnings growth outlined in management's guidance. The company has already seen the benefit of new rates, with an increase of $23.8 million from new rates contributing to its fourth-quarter operating income. Successfully navigating these cases is critical for translating the company's capital investment into higher returns.

Equally important is the execution of the substantial capital expenditure plan. ONE Gas plans to spend $750 million in 2025 on pipeline integrity, system extensions, and capacity increases. This is not optional spending; it is the cost of maintaining its regulated monopoly and customer base. The market will be watching to see if the company can manage this investment efficiently, without cost overruns, and if the resulting infrastructure upgrades continue to support the growth in customer additions and service reliability. The successful implementation of new rates and the disciplined use of capital are the twin engines that must work in concert to drive earnings toward the guided range.

On the risk side, two factors are inherent to the business model. First, there is the pronounced seasonality of natural gas demand. A substantial portion of residential heating needs creates a clear cycle, with higher demand during the months of November through March. Warmer-than-normal winters, as experienced in the fourth quarter of 2025, can directly pressure profitability. While weather normalization mechanisms provide some relief, they are not a perfect hedge. Second, the company faces long-term competition from other clean energy sources. This is a structural challenge to the utility's core business, though its regulated status and cost advantages provide a buffer. The key is to monitor whether this competition begins to materially impact customer growth or pricing power.

The bottom line is that the investment thesis is now in a phase of validation. The market has priced in growth, so the company must deliver on its capital plan and regulatory milestones. For a patient investor, the setup offers a clear checklist: watch for the resolution of pending rate cases, monitor the progress and cost control of the $750 million capex program, and remain aware of the seasonal and competitive headwinds. Success on these fronts will confirm the durability of the moat and the path to intrinsic value.
