ONE Gas Announces First Quarter 2026 Financial Results; Affirms 2026 Financial GuidanceMay 4, 2026 4:15 PM
PR Newswire (US) Declares Second Quarter DividendAnalyst call and webcast scheduled tomorrow, May 5 at 11 a.m. EDTTULSA, Okla., May 4, 2026 /PRNewswire/ -- ONE Gas, Inc. (NYSE: OGS) today announced its first quarter 2026 financial results, affirmed its 2026 financial guidance and declared its quarterly dividend."Our positive performance through a historically warm winter underscores the resilience of our business model and our ability to drive long-term value while sustaining customer affordability," said Robert S. McAnnally, chief executive officer. "We are confident in our strategic plan and remain on track to achieve our 2026 financial guidance."FINANCIAL RESULTS & HIGHLIGHTSFirst quarter 2026 net income was $128.7 million, or $2.04 per diluted share, compared with $119.4 million, or $1.98 per diluted share, in the same period last year;First quarter 2026 adjusted net income was $133.4 million, or $2.11 per diluted share, compared with $120.1 million, or $1.99 per diluted share, in the same period last year;While weather across the Company's service areas was 20.5 percent warmer than normal and 24.6 percent warmer than the prior year, the impact on operating income was tempered by weather normalization mechanisms;In February 2026, the Company entered into an at-the-market equity distribution agreement under which it may issue and sell shares of common stock with an aggregate offering price up to $225 million;For the ninth consecutive year, ONE Gas was awarded the American Gas Association Safety Achievement Award for excellence in employee safety; andThe board of directors declared a quarterly dividend of $0.68 per share ($2.72 annualized), payable on June 2, 2026, to shareholders of record at the close of business on May 18, 2026.FIRST QUARTER 2026 FINANCIAL PERFORMANCEONE Gas reported operating income of $189.6 million in the first quarter, compared with $180.5 million in the first quarter 2025, which primarily reflects an increase of $27.3 million from new rates.This increase was partially offset by:an increase of $6.8 million in employee-related costs due, in part, to planned investments in the Company's workforce;an increase of $1.3 million in outside services; anda decrease of $8.9 million in revenue due to lower sales and transport volumes, net of the impact of weather normalization mechanisms.Excluding interest related to KGSS-I securitized bonds, net interest expense decreased $3.0 million for the three months ending March 31, 2026. The decrease in interest expense is primarily due 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 $9.5 million and $8.1 million for the three months ended March 31, 2026, and 2025, respectively.Capital expenditures and asset removal costs were $169.6 million for the first quarter 2026 compared with $177.7 million in the same period last year, primarily representing expenditures for system integrity and extension of service to new areas.REGULATORY ACTIVITIES UPDATEIn April 2026, Kansas House Bill 2435 was signed into law, amending the Gas System Reliability Surcharge (GSRS) statute effective July 1, 2026. The amendment expands the qualifying infrastructure investments eligible for recovery to include all utility plant investments (excluding allocated corporate costs other than cyber-security related investments), increases the maximum monthly residential surcharge to $1.35 from $0.80 and provides added filing flexibility by allowing one GSRS filing per calendar year, rather than once every 365 days.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 February 2026, Oklahoma Natural Gas filed its annual Performance-Based Rate Change 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. A hearing is scheduled for June 11, 2026. Rates may be implemented subject to refund on June 26, 2026.2026 FINANCIAL GUIDANCEONE Gas affirmed the financial guidance it issued on Dec. 1, 2025, as supplemented on Feb. 18, 2026. For 2026, net income is expected to be in the range of $294 million to $302 million, or $4.65 to $4.77 per diluted share, while adjusted net income is expected to be in the range of $306 million to $314 million, or $4.83 to $4.95 per diluted share. The Company continues to expect long-term GAAP and adjusted net income growth of 7 to 9 percent and GAAP and adjusted net income per diluted share growth of 5 to 7 percent, consistent with its established five-year financial outlook.Capital investments, including asset removal costs, are expected to be approximately $800 million in 2026. Capital investments for extensions to new customers are expected to be approximately $230 million.EARNINGS CONFERENCE CALL AND WEBCASTThe ONE Gas executive management team will host a conference call on Tuesday, May 5, 2026, at 11 a.m. Eastern Daylight Time (10 a.m. Central Daylight Time).

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 base 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.

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; andour 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. 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.

PR Newswire (US)

Analyst call and webcast scheduled tomorrow, Feb. 19 at 11 a.m. ESTTULSA, Okla., Feb. 18, 2026 /PRNewswire/ -- ONE Gas, Inc. (NYSE: OGS) today announced its fourth quarter and full year 2025 financial results, which include diluted earnings per share of $1.42 and $4.37, respectively. The Company also provided non-GAAP adjustments to both earnings and its 2026 financial guidance to capture the full impact of a regulatory mechanism intended to mitigate regulatory lag. Adjusted net income was $1.48 per diluted share for the fourth quarter, and $4.48 per diluted share for the full year 2025. For 2026, non-GAAP earnings are expected to range from $306 million to $314 million, or $4.83 to $4.95 per diluted share.

"Our team delivered strong operational and financial results in 2025, reflecting disciplined execution and a commitment to safely serving our communities," said Robert S. McAnnally, president and chief executive officer. "Looking ahead, we see meaningful opportunity in both residential and large-load growth, supporting long-term value creation and affordability for our customers."FINANCIAL RESULTS & HIGHLIGHTSFourth quarter 2025 net income was $86.3 million, or $1.42 per diluted share, compared with $77.0 million, or $1.34 per diluted share, in the same period last year;Fourth quarter 2025 adjusted net income was $89.7 million, or $1.48 per diluted share, compared with $77.5 million, or $1.35 per diluted share, in the same period last year;Full year 2025 net income was $264.2 million, or $4.37 per diluted share, compared with $222.9 million, or $3.91 per diluted share, in 2024;Full year 2025 adjusted net income was $271.0 million, or $4.48 per diluted share, compared with $224.8 million, or $3.94 per diluted share, in 2024;In December, the Company settled 2,633,700 million shares of our common stock under forward contracts for net proceeds of $205.0 million;Full year 2025 capital expenditures and asset removal costs were $759.5 million compared with $762.1 million in 2024; andOn Jan. 20, 2026, ONE Gas increased the dividend for the first quarter 2026 by 1 cent to $0.68 per share ($2.72 annualized), payable March 6, 2026, to shareholders of record at the close of business Feb. 20, 2026.FOURTH QUARTER 2025 FINANCIAL PERFORMANCEONE Gas reported operating income of $139.7 million in the fourth quarter, compared with $124.3 million in the fourth quarter 2024, which primarily reflects:an increase of $23.8 million from new rates; andan increase of $1.3 million in residential sales due primarily to net customer growth in Oklahoma and Texas.The increases were partially offset by:an increase of $4.2 million in employee-related costs, due in part to annual salary increases implemented during the quarter;an increase of $3.8 million in depreciation and amortization expense primarily from additional capital investment; andan increase of $3.3 million due to outside services, due in part to our decision to execute some projects earlier than initially planned.Weather was 22.7 percent warmer than normal for the three months ended Dec. 31, 2025. The impact on operating income was mitigated by weather normalization mechanisms.Excluding interest related to KGSS-I securitized bonds, net interest expense decreased $2.9 million for the three months ending Dec. 31, 2025. 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 $5.6 million and $12.3 million for the three months ended Dec. 31, 2025, and 2024, respectively.Capital expenditures and asset removal costs were $184.1 million for the fourth quarter 2025 compared with $190.4 million in the same period last year, primarily representing expenditures for system integrity and extension of service to new areas.FULL YEAR 2025 FINANCIAL PERFORMANCEOperating income for the twelve-month 2025 period was $457.5 million, compared with $399.0 million in 2024, which primarily reflects:an increase of $116.0 million from new rates; andan increase of $6.6 million in residential sales due primarily to net customer growth in all three states.These increases were partially offset by:an increase of $20.6 million in depreciation expense due to additional capital expenditures being placed in service;an increase of $17.0 million in employee-related costs;an increase of $14.7 million in ad-valorem taxes; anda 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, net interest expense decreased $3.0 million for the twelve months ended Dec. 31, 2025. 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 $17.6 million and $25.7 million for the twelve months ended Dec. 31, 2025, and 2024, respectively.Capital expenditures and asset removal costs were $759.5 million for the twelve-month 2025 period compared with $762.1 million in the same period last year.In December, the Company settled 2,633,700 million shares of our common stock under forward contracts for net proceeds of $205.0 million.REGULATORY ACTIVITIES UPDATEIn June 2025, Texas Gas Service filed a rate case for customers in the Central-Gulf, West-North, and Rio Grande Valley service areas. The Railroad Commission of Texas ultimately approved a $14.4 million revenue increase and the consolidation of all service areas into a single division, based on a 59.9% equity ratio and a 9.8% ROE. New rates became effective January 27, 2026.2026 FINANCIAL GUIDANCEOn Dec. 1, 2025, ONE Gas announced that its 2026 net income is expected to be in the range of $294 million to $302 million, with earnings per diluted share of $4.65 to $4.77.The Company expects 2026 adjusted net income to be in the range of $306 million to $314 million, with adjusted net income per diluted share of $4.83 to $4.95.ONE Gas expects long-term adjusted net income growth of 7 to 9 percent and adjusted net income per diluted share growth of 5 to 7 percent, consistent with its established five-year financial outlook. These growth rates are based on adjusted 2025 actual results, including adjusted net income of $271 million and adjusted net income per diluted share of $4.48.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.EARNINGS CONFERENCE CALL AND WEBCASTThe ONE Gas executive management team will host a conference call on Thursday, February 19, 2026, at 11 a.m. Eastern Standard Time (10 a.m. Central Standard Time).

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 base 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.

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

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

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; andour 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
