About this update from One Gas, Inc.
Declares Third Quarter Dividend Analyst call and webcast scheduled tomorrow, Aug. 5 at 11 a.m. EDT TULSA, Okla. , Aug. 4, 2026 /PRNewswire/ -- ONE Gas, Inc. (NYSE: OGS) today announced its second quarter financial results and raised its 2026 adjusted earnings expectations to the upper half of the previously announced financial guidance ranges. The Company also declared its quarterly dividend. "Our strong second quarter and first-half results reflect the continued execution of our growth strategy and the benefits of operating in constructive jurisdictions. This performance gives us the confidence to raise our adjusted earnings expectations for the full year," said Robert S. McAnnally, chief executive officer. "We delivered these results while maintaining our focus on reliability and affordability for customers and creating long-term value for shareholders." FINANCIAL RESULTS & HIGHLIGHTS The Company raised its 2026 adjusted net income and earnings per diluted share expectations to the upper half of the respective $306 million to $314 million and $4.83 to $4.95 ranges; Second quarter 2026 adjusted net income was $52.1 million , or $0.82 per diluted share, compared with $32.7 million , or $0.54 per diluted share, in the same period last year; Year-to-date 2026 adjusted net income was $185.5 million , or $2.94 per diluted share, compared with $152.8 million , or $2.53 per diluted share, in 2025 ; Second quarter 2026 net income was $46.8 million , or $0.74 per diluted share, compared with $32.0 million , or $0.53 per diluted share, in the same period last year; Year-to-date 2026 net income was $175.5 million , or $2.78 per diluted share, compared with $151.5 million , or $2.51 per diluted share, in 2025 ; and The board of directors declared a quarterly dividend of $0.68 per share ($2.72 annualized), payable on August 31, 2026, to shareholders of record at the close of business on August 17, 2026. SECOND QUARTER 2026 FINANCIAL PERFORMANCE ONE Gas reported operating income of $82.7 million in the second quarter, compared with $71.9 million in the second quarter 2025 , which primarily reflects : an increase of $16.4 million in revenue from new rates; an increase of $1.4 million in residential sales due primarily to net customer growth in Oklahoma and Texas; and an increase of $1.3 million in line extension revenue in Oklahoma. These increases were partially offset by: an increase of $7.4 million in employee-related costs; an increase of $1.1 million in outside services; and an increase of $1.1 million in fleet expense. Weather was 42 percent warmer than normal and 28 percent warmer than the prior year for the three months ended June 30, 2026. The impact on operating income was mitigated by weather normalization mechanisms. Excluding interest related to KGSS-I securitized bonds, net interest expense decreased $3.8 million for the three months ending June 30 , 2026 . The decrease in interest expense is due primarily to commercial paper borrowings at lower rates and the implementation of Texas House Bill 4384. Income tax expense includes a credit for amortization of the regulatory liability associated with excess deferred income taxes (EDIT) of $3.3 million and $2.1 million for the three months ended June 30 , 2026 , and 2025 , respectively. Capital expenditures and asset removal costs were $188.3 million for the second quarter 2026 compared with $190.1 million in the same period last year, primarily representing expenditures for system integrity and extension of service to new areas. YEAR-TO-DATE 2026 FINANCIAL PERFORMANCE Operating income for the six months ended June 30, 2026 , was $272.3 million, compared with $252.4 million in 2025 , which primarily reflects: an increase of $43.7 million from new rates; an increase of $3.2 million in residential sales due primarily to net customer growth in Oklahoma and Texas; and an increase of $1.8 million from released transportation capacity to other shippers in Kansas. These increases were partially offset by: an increase of $13.2 million in employee-related costs; an increase of $3.4 million in outside services; an increase of $1.3 million in fleet expense; and a decrease of $10.6 million in revenue due to lower sales and transport volumes, net of the impact of weather normalization mechanisms. Weather was 23 percent warmer than normal and 25 percent warmer than the prior year for the six months ended June 30, 2026 . The impact on operating income was mitigated by weather normalization mechanisms. Excluding interest related to KGSS-I securitized bonds, net interest expense decreased $6.7 million for the six months ended June 30, 2026 . The decrease in interest expense is due primarily to commercial paper borrowings at lower rates and the implementation of Texas House Bill 4384. Income tax expense includes a credit for amortization of the regulatory liability associated with EDIT of $12.8 million and $10.2 million for the six months ended June 30 , 2026 , and 2025 , respectively. Capital expenditures and asset removal costs were $357.9 million for the six-month 2026 period compared with $367.8 million in the same period last year, primarily representing expenditures for system integrity and extension of service to new areas. REGULATORY ACTIVITIES UPDATE In July 2026, Kansas Gas Service submitted an application to the Kansas Corporation Commission requesting an increase of approximately $14.3 million related to its Gas System Reliability Surcharge to be effective October 2026. The filing includes expanded infrastructure investments as defined by Kansas House Bill 2435. In March 2026, Texas Gas Service made a Gas Reliability Infrastructure Program filing for all customers requesting a $36.9 million revenue increase to be effective in July 2026. In June 2026, the Texas Railroad Commission approved an increase of $36.9 million, and new rates became effective in July 2026. In February 2026, Oklahoma Natural Gas filed its annual Performance-Based Rate Change (PBRC) application for the test year ended December 2025. The filing includes a requested $28.7 million base rate revenue increase, $2.6 million energy efficiency incentive and $14.4 million of estimated EDIT to be credited to customers in 2027. At the hearing on June 11, 2026, the administrative law judge recommended approval of the application as filed. Subsequent to the hearing, exceptions to the administrative law judge's oral ruling were filed at the Oklahoma Corporation Commission as well as an appeal to the Oklahoma Supreme Court. Interim rates subject to refund were implemented on June 26, 2026, in compliance with the PBRC tariff . 2026 FINANCIAL GUIDANCE Based on strong performance during the first half of 2026 and anticipated benefits associated with Texas House Bill 4384, the Company has raised its 2026 adjusted earnings expectations to the upper half of its previously issued 2026 financial guidance ranges, which called for adjusted net income of $306 million to $314 million and adjusted net income per diluted share of $4.83 to $4.95. Capital investments, including asset removal costs, are expected to be approximately $800 million in 2026, primarily targeted for system integrity and replacement projects. Capital investments for extensions to new customers are expected to be approximately $230 million of the $800 million.

NON-GAAP DISCLOSURE STATEMENT This news release includes financial results and guidance for ONE Gas with respect to adjusted net income and adjusted net income per share, which are non-GAAP financial measures as defined by the Securities and Exchange Commission. Adjusted net income and adjusted net income per share are calculated as GAAP net income plus the deferral of an equity portion of a carrying cost attributable to shareholders' investment capitalized for regulatory purposes but not for financial reporting purposes. These carrying costs relate to property, plant and equipment that has been placed in service, but not yet reflected in rates. Adjusted net income and adjusted net income per share should not be considered in isolation or as a substitute for GAAP net income or GAAP earnings per share. Management believes these non‑GAAP measures provide useful information because they offer a more complete view of our overall regulatory economics, reflect the period-specific effects of certain regulatory mechanisms designed to mitigate regulatory lag associated with property, plant and equipment placed in service prior to regulatory action, and reflect the impact of regulatory timing differences that arise under the Company's rate-setting framework. These adjustments, net of applicable tax effects, are expected to recur as a result of the Company's regulatory framework and are a consistent part of our earnings profile. A reconciliation of the Company's GAAP net income and GAAP earnings per share to adjusted net income and adjusted net income per share is provided in the Appendix. ONE Gas, Inc.

In addition to any assumptions and other factors referred to specifically in connection with the forward-looking statements, factors that could cause our actual results to differ materially from those contemplated in any forward-looking statement include, among others, the following: our ability to recover costs, income taxes and amounts equivalent to the cost of property, plant and equipment, regulatory assets and our allowed rate of return in our regulated rates or other recovery mechanisms; cyber-attacks, which, according to experts, continue to increase in volume and sophistication, or breaches of technology systems that could disrupt our operations or result in the loss or exposure of confidential or sensitive customer, employee, vendor, counterparty, or Company information; further, increased remote working arrangements have required enhancements and modifications to our information technology infrastructure (e.g. Internet, Virtual Private Network, remote collaboration systems, etc.), and any failures of the technologies, including third-party service providers, that facilitate working remotely could limit our ability to conduct ordinary operations or expose us to increased risk or effect of an attack; our ability to manage our operations and maintenance costs; changes in regulation of natural gas distribution services, particularly those in Oklahoma, Kansas and Texas; the economic climate and, particularly, its effect on the natural gas requirements of our residential and commercial customers; the length and severity of a pandemic or other health crisis which could significantly disrupt or prevent us from operating our business in the ordinary course for an extended period; competition from alternative forms of energy, including, but not limited to, electricity, solar power, wind power, geothermal energy and biofuels; adverse weather conditions and variations in weather, including seasonal effects on demand and/or supply, the occurrence of severe storms in the territories in which we operate, climate change, and the related effects on supply, demand, and costs; indebtedness could make us more vulnerable to general adverse economic and industry conditions, limit our ability to borrow additional funds and/or place us at competitive disadvantage compared with competitors; our ability to secure reliable, competitively priced and flexible natural gas transportation, storage, and supply, including decisions by natural gas producers to reduce production or shut-in producing natural gas wells and expiration of existing supply and transportation and storage arrangements that are not replaced with contracts with similar terms and pricing; our ability to complete necessary or desirable expansion or infrastructure development projects, which may delay or prevent us from serving our customers or expanding our business; operational and mechanical hazards or interruptions; adverse labor relations; the effectiveness of our strategies to reduce earnings lag, revenue protection strategies and risk mitigation strategies, which may be affected by risks beyond our control such as commodity price volatility, counterparty performance or creditworthiness and interest rate risk; the capital-intensive nature of our business, and the availability of and access to, in general, funds to meet our debt obligations prior to or when they become due and to fund our operations and capital expenditures, either through (i) cash on hand, (ii) operating cash flow, or (iii) access to the capital markets and other sources of liquidity; our ability to obtain capital on commercially reasonable terms, or on terms acceptable to us, or at all; limitations on our operating flexibility, earnings and cash flows due to restrictions in our financing arrangements; cross-default provisions in our borrowing arrangements, which may lead to our inability to satisfy all of our outstanding obligations in the event of a default on our part; changes in the financial markets during the periods covered by the forward-looking statements, particularly those affecting the availability of capital and our ability to refinance existing debt and fund investments and acquisitions to execute our business strategy; actions of rating agencies, including the ratings of debt, general corporate ratings and changes in the rating agencies' ratings criteria; changes in inflation and interest rates; our ability to recover the costs of upstream transportation, storage, and natural gas purchased for our customers and any related financing required to support our purchase of natural gas supply; impact of potential impairment charges; volatility and changes in markets for natural gas and our ability to secure additional and sufficient liquidity on reasonable commercial terms to cover costs associated with such volatility; possible loss of local distribution company franchises or other adverse effects caused by the actions of municipalities; payment and performance by counterparties and customers as contracted and when due, including our counterparties maintaining ordinary course terms of supply and payments; changes in existing or the addition of new environmental, safety, tax, cybersecurity and other laws or regulations to which we and our subsidiaries are subject, including those that may require significant expenditures, significant increases in operating costs or, in the case of noncompliance, substantial fines or penalties; the effectiveness of our risk-management policies and procedures, and employees violating our risk-management policies; the uncertainty of estimates, including accruals and costs of environmental remediation; advances in technology, including technologies that increase efficiency or that improve electricity's competitive position relative to natural gas; population growth rates and changes in the demographic patterns of the markets we serve in Oklahoma, Kansas and Texas, and economic conditions in these areas; acts of nature and naturally occurring disasters; political unrest and the potential effects of threatened or actual terrorism and war; the sufficiency of insurance coverage to cover losses; the effects of our strategies to reduce tax payments; changes in accounting standards; changes in corporate governance standards; existence of material weaknesses in our internal controls; our ability to comply with all covenants in our indentures and the ONE Gas Credit Agreement, a violation of which, if not cured in a timely manner, could trigger a default of our obligations; our ability to attract and retain talented employees, management and directors, and shortage of skilled-labor; unexpected increases in the costs of providing health care benefits, along with pension and postemployment health care benefits, as well as declines in the discount rates on, declines in the market value of the debt and equity securities of, and increases in funding requirements for, our defined benefit plans; and our ability to successfully complete merger, acquisition or divestiture plans, regulatory or other limitations imposed as a result of a merger, acquisition or divestiture, and the success of the business following a merger, acquisition or divestiture. These factors are not necessarily all of the important factors that could cause actual results to differ materially from those expressed in any of our forward-looking statements.
