Analyst call and webcast scheduled tomorrow, November 4 at 11 a.m. EST

TULSA, Okla., Nov. 3, 2025 /PRNewswire/ -- ONE Gas, Inc. (NYSE:OGS) today announced its third quarter financial results, narrowed its 2025 financial guidance and declared its quarterly dividend.

"Our third-quarter performance reflects disciplined execution of our strategy and continued operational efficiency," said Robert S. McAnnally, president and chief executive officer. "The narrowed financial outlook aligns with year-to-date results and reinforces our confidence in delivering full-year guidance. As we approach year-end, we remain focused on sustainable growth, prudent capital deployment and delivering long-term value for our shareholders."

THIRD QUARTER 2025 FINANCIAL RESULTS & HIGHLIGHTS

Third quarter 2025 net income was $26.5 million, or $0.44 per diluted share, compared with $19.3 million, or $0.34 per diluted share, in the third quarter 2024;
Year-to-date 2025 net income was $177.9 million, or $2.94 per diluted share, compared with $145.8 million, or $2.56 per diluted share, in the same period last year;
The Company narrowed its 2025 diluted earnings per share guidance to a range of $4.34 to $4.40, from a previous range of $4.32 to $4.42; and
The board of directors declared a quarterly dividend of $0.67 per share ($2.68 annualized), payable on December 1, 2025, to shareholders of record at the close of business on November 14, 2025.

THIRD QUARTER 2025 FINANCIAL PERFORMANCE

ONE Gas reported operating income of $65.4 million in the third quarter, compared with $59.5 million in the third quarter 2024, which primarily reflects:

an increase of $19.2 million from new rates; and
an increase of $1.4 million in residential sales due primarily to net customer growth in Oklahoma and Texas.

The increases were partially offset by:

an increase of $4.8 million in depreciation and amortization expense primarily from additional capital investment;
an increase of $4.1 million due to ad valorem taxes;
an increase of $3.8 million in employee-related costs; and
an increase of $1.0 million due to outside services.

Excluding interest related to KGSS-I securitized bonds, interest expense, net decreased $3.4 million for the three months ended September 30, 2025, compared to the same period last year, primarily due to lower rates on commercial paper borrowings.

Income tax expense reflects credits for amortization of the regulatory liability associated with excess deferred income taxes (EDIT) of $1.7 million and $1.5 million for the three months ended September 30, 2025 and 2024, respectively.

Capital expenditures and asset removal costs were $207.6 million for the third quarter 2025 compared with $197.7 million in the same period last year, primarily representing expenditures for system integrity and extension of service to new areas.

YEAR-TO-DATE 2025 FINANCIAL PERFORMANCE

Operating income for the nine months ended September 30, 2025, was $317.7 million, compared with $274.6 million in 2024, which primarily reflects:

an increase of $92.2 million from new rates; and
an increase of $5.3 million in residential sales due primarily to net customer growth in Oklahoma and Texas.

These increases were partially offset by:

an increase of $16.8 million in depreciation and amortization expense primarily from additional capital investment;
an increase of $13.8 million due to ad valorem taxes;
an increase of $12.8 million in employee-related costs;
an increase of $2.5 million in insurance expense;
an increase of $2.1 million in bad debt expense;
an increase of $1.3 million in information technology expense; and
a carrying charge of $2.9 million refunded to Oklahoma customers from the settlement of a disputed gas purchase invoice.

Excluding interest related to KGSS-I securitized bonds, interest expense, net for the nine months ended September 30, 2025 was in line with the same period last year.

Income tax expense includes a credit for amortization of the regulatory liability associated with EDIT of $11.9 million and $13.4 million for the nine months ended September 30, 2025 and 2024, respectively.

Capital expenditures and asset removal costs were $575.4 million for the nine-month 2025 period compared with $571.7 million in the same period last year, primarily representing expenditures for system integrity and extension of service to new areas.

REGULATORY ACTIVITIES UPDATE

In June 2025, Texas Gas Service filed a rate case for all customers in the Central-Gulf, West-North and Rio Grande Valley service areas, requesting a $41.1 million revenue increase and proposing to consolidate all service areas into a single division. Texas Gas Service filed this rate case directly with the cities in each service area, which includes the cities of Austin and El Paso, and the Railroad Commission of Texas (RRC) for the unincorporated areas. This filing is based on a 10.4 percent return on equity and a 59.9 percent common equity ratio. New rates are expected to take effect in the first quarter of 2026.

In April 2025, Texas Gas Service made a Gas Reliability Infrastructure Program filing for all customers in the Rio Grande Valley service area, requesting a $3.2 million increase to be effective in September 2025. In August 2025, the RRC approved an increase of $2.9 million, and new rates became effective in September 2025.

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. In July 2025, the KCC approved a $7.2 million increase effective August 2025.

In February 2025, Oklahoma Natural Gas filed its annual Performance-Based Rate Change application for the test year ended December 2024. The filing included a requested $41.5 million base rate revenue increase, a $2.4 million energy efficiency incentive, and $13.2 million of estimated EDIT to be credited to customers in 2026. A settlement agreement was reached among the parties, which included a $41.1 million base rate revenue increase, a $2.4 million energy efficiency incentive, and $17.9 million of estimated EDIT to be credited to customers beginning in February 2026. Interim rates, subject to refund, were implemented in June 2025. The Oklahoma Corporation Commission issued a final order approving the settlement in July 2025.

2025 FINANCIAL GUIDANCE NARROWED

The Company narrowed its 2025 financial guidance, with net income expected to be in the range of $262 million to $266 million, compared with its previously announced range of $261 million to $267 million. Earnings per diluted share are expected to be approximately $4.34 to $4.40, compared with the previously announced range of $4.32 to $4.42. There was no change to the respective midpoints of the 2025 net income and earnings per share guidance, both of which remain 2.5% above the original guidance forecasts for the year.

Capital expenditures, including asset removal costs, are still expected to be approximately $750 million in 2025.

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;

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, and 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 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 natural gas purchased for our customers and any related financing required to support our purchase of natural gas supply;

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

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 September 30, 2025, include $11.2 million associated with KGSS-I, which is offset by $7.6 million in operating and amortization expense and $3.6 million in interest expense, net. Compared to the same three month period last year, revenues increased $0.7 million, which was offset by a $1.1 million increase in operating and amortization expense and a $0.4 million decrease in interest expense, net.

Revenues for the nine months ended September 30, 2025, include $36.1 million associated with KGSS-I, which is offset by $24.8 million in operating and amortization expense and $11.1 in interest expense, net. Compared to the same nine month period last year, revenues increased $2.3 million, which was offset by a $3.4 million increase in amortization and operating expense and a $1.1 million decrease in interest expense, net.
