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.

•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;

•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 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;

Other factors could also have material adverse effects on our future results. These and other risks are described in greater detail in Part 1, Item 1A, Risk Factors, in our Annual Report. All forward-looking statements attributable to us or persons acting on our behalf are expressly qualified in their entirety by these factors.

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.

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