ONE Gas Announces First Quarter 2025 Financial Results;

Expects to Achieve the Upper Half of 2025 Financial Guidance;

Declares Second Quarter Dividend

Analyst call and webcast scheduled tomorrow, May 6 at 11 a.m. EST

TULSA, Okla. - May 5, 2025 - ONE Gas, Inc. (NYSE: OGS) today announced its first quarter financial results, said that it expects to achieve the upper half of its previously announced 2025 financial guidance and declared its quarterly dividend.

“We achieved strong financial results in the first quarter due to our effective regulatory strategy and a disciplined approach to managing expenses,” said Robert S. McAnnally, president and chief executive officer. “Safety remains our top priority as we serve our customers and meet the growing demand for natural gas across our service territory.”

FIRST QUARTER 2025 FINANCIAL RESULTS & HIGHLIGHTS

•First quarter 2025 net income was $119.4 million, or $1.98 per diluted share, compared with $99.3 million, or $1.75 per diluted share, in the first quarter 2024;

•While weather across the Company's service areas was 5 percent colder than normal and 16 percent colder than the first quarter last year, the impact on operating income was largely tempered by regulatory weather normalization mechanisms; and

•The board of directors declared a quarterly dividend of $0.67 per share ($2.68 annualized), payable on June 3, 2025, to shareholders of record at the close of business on May 19, 2025.

FIRST QUARTER 2025 FINANCIAL PERFORMANCE

ONE Gas reported operating income of $180.5 million in the first quarter, compared with $145.9 million in the first quarter 2024, which primarily reflects:

•an increase of $51.9 million from new rates; and

•an increase of $2.3 million in residential sales due primarily to net customer growth in Oklahoma and Texas.

The increase was partially offset by:

•an increase of $5.1 million in depreciation and amortization expense from additional capital investment;

•an increase of $4.7 million in ad valorem taxes, primarily due to regulatory outcomes which took effect during the quarter;

•an increase of $3.2 million in employee-related costs, due primarily to strategic investments in the Company’s workforce and ongoing in-sourcing efforts, which have strengthened operational oversight and improved overall expense management; and

•a net decrease of $6.5 million due to the impact of weather normalization mechanisms, largely offset by higher sales volumes.

Excluding interest related to KGSS-I securitized bonds, net interest expense increased $4.7 million for the three months ending March 31, 2025. The increase in interest expense is due primarily to the reopening of the outstanding 5.10 percent senior notes in August 2024 to issue an additional $250 million and higher average commercial paper balances.

Income tax expense reflects credits for amortization of the regulatory liability associated with excess deferred income taxes (EDIT) of $8.1 million and $10.1 million for the three months ended March 31, 2025, and 2024, respectively.

Capital expenditures and asset removal costs were $177.7 million for the first quarter 2025 compared with $179.4 million in the same period last year, primarily representing expenditures for system integrity and extension of service to new areas.

REGULATORY ACTIVITIES UPDATE

In April 2025, Kansas Gas Service submitted an application to the Kansas Corporation Commission (KCC) requesting an increase of approximately $7.2 million related to its Gas System Reliability Surcharge. The KCC has until August 2025 to issue an order.

In April 2025, Texas Gas Service made Gas Reliability Infrastructure Program filings for all customers in the Rio Grande Valley service area, requesting a $3.2 million increase to be effective in September 2025.

In February 2025, Oklahoma Natural Gas filed its annual Performance-Based Rate Change application for the test year ended December 2024. The filing includes a requested $41.5 million

base rate revenue increase, $2.4 million energy efficiency incentive and $13.2 million of EDIT to be credited to customers in 2026. A hearing is scheduled for June 12, 2025.

In February 2025, Texas Gas Service made Gas Reliability Infrastructure Program filings for customers in each of the Central-Gulf and West-North service areas, requesting increases of $15.4 million and $8.2 million, respectively, to be effective in June 2025.

2025 FINANCIAL GUIDANCE

The company expects to achieve the upper half of the 2025 financial guidance shared on Dec. 5, 2024, which provided for net income in the range of $254 million to $261 million and earnings per diluted share of $4.20 to $4.32.

Capital investments, including asset removal costs, are expected to be approximately $750 million in 2025, primarily targeted for system integrity and replacement projects. Capital investments for extensions to new customers are expected to be approximately $180 million.

•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 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;

•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;

KGSS-I SECURITIZATION

In November 2022, Kansas Gas Service Securitization I, L.L.C. (KGSS-I) issued $336 million of securitized utility tariff bonds. KGSS-I used the proceeds from the issuance to purchase the Securitized Utility Tariff Property from Kansas Gas Service, pay for debt issuance costs, and reimburse Kansas Gas Service for upfront securitization costs paid on behalf of KGSS-I.

Revenues for the three months ended March 31, 2025, include $11.6 million associated with KGSS-I, which is offset by $7.8 million in operating and amortization expense and $3.8 million in net interest expense. Revenues were in line compared to the same period last year, which was offset by a $0.3 million increase in operating and amortization expense and a $0.3 million decrease in net interest expense.

The following table summarizes the impact of KGSS-I on the consolidated balance sheets, for the periods indicated:
