FIRST QUARTER 2020 FINANCIAL PERFORMANCE

ONE Gas reported operating income of $133.2 million in the first quarter 2020, compared with $127.6 million in the first quarter 2019.

Net margin, which is comprised of total revenues less cost of natural gas, increased by $6.2 million compared with first quarter 2019, which primarily reflects:

• A $7.9 million increase from new rates primarily in Kansas and Texas;

• A $2.5 million increase attributed to net residential customer growth; and

• A $0.9 million increase in rider and surcharge recoveries due to a higher ad-valorem surcharge in Kansas; offset by

• A $3.9 million decrease due to lower sales volumes, net of weather normalization, primarily in Kansas and Oklahoma from warmer weather in 2020 compared with the same period in 2019. For the first quarter 2020, heating degree days in Kansas and Oklahoma were 19% and 21% lower, respectively, compared with the same period in 2019; and

• A $1.1 million decrease due to lower transportation volumes in Kansas.

First quarter 2020 operating costs were $121.4 million, compared with $124.5 million in the first quarter 2019, which primarily reflects:

• A $2.0 million decrease in legal-related costs; and

• A $1.6 million decrease in employee-related costs, which reflects a $4.3 million decrease in the expense associated with the change in the value of the liabilities for nonqualified employee benefit plans and a $1.2 million increase in labor costs; offset by

• A $0.8 million increase in bad debt expense.

Depreciation and amortization expense for the first quarter 2020 was $47.5 million, compared with $43.8 million in the first quarter 2019, due primarily to an increase in depreciation expense from capital investments placed in service, higher depreciation rates in Kansas and an increase in amortization of the ad-valorem surcharge rider in Kansas.

For the first quarter 2020, other expense, net, increased $6.2 million compared with the same period last year, due primarily to a $6.7 million decrease in the value of investments associated with nonqualified employee benefit plans.

Income tax expense includes a credit for amortization of excess accumulated deferred income taxes (EDIT) of $6.9 million and $6.7 million for the quarters ended March 31, 2020, and 2019, respectively.

Capital expenditures and asset removal costs increased $29.0 million for the first quarter 2020 compared with the same period last year, due primarily to increased system integrity activities and extending service to new areas.

Key Statistics: More detailed information is listed in the tables located in the Appendix.

• Actual heating degree days across the company’s service areas were 4,714 in the first quarter 2020, 10% warmer than normal and 19% warmer than the same period last year;

REGULATORY UPDATE

Oklahoma

In April 2020, the Public Utility Division of the Oklahoma Corporation Commission is expected to file an application to allow all utilities in Oklahoma to defer, as a regulatory asset, incremental expenses, including increased bad debt expenses and/or impacts to revenue that are outside the utility's control or a direct result of the utility's COVID-19 response, beginning March 13, 2020. Regulatory action on the proposed application is expected in the second quarter 2020.

In February 2020, Oklahoma Natural Gas filed its fourth annual Performance-Based Rate Change (PBRC) application following the general rate case that was approved in January 2016. The filing includes a requested base rate increase of $11.8 million and a $12.2 million credit

associated with EDIT. If approved, new rates are expected to become effective in the third quarter of 2020, and EDIT is expected to be credited to customers in the first quarter 2021.

Kansas

In April 2020, Kansas Gas Service filed an application with the Kansas Corporation Commission for an Accounting Authority Order to accumulate and defer certain incremental costs incurred, including bad debt expenses and lost revenues, as well as associated carrying costs related to COVID-19 beginning March 1, 2020, for recovery in Kansas Gas Services' next rate case filing. Regulatory action on the proposed application is expected in the second quarter 2020.

Texas

In April 2020, the Railroad Commission of Texas issued an order authorizing utilities to use an accounting mechanism and a subsequent process through which Texas Gas Service may seek future recovery of incremental expenses resulting from the effects of COVID-19, including bad debt and associated credit and collections costs, and other reasonable and necessary incremental costs to address the impact of COVID-19, beginning March 13, 2020.

West Texas Service Area

In March 2020, Texas Gas Service made Gas Reliability Infrastructure Program (GRIP) filings for all customers in the West Texas service area, requesting a $4.7 million increase to be effective in the third quarter 2020.

Central Texas Service Area

In 2019, Texas Gas Service filed a rate case for all customers in the Central Texas and Gulf Coast service areas, seeking a $15.6 million rate increase and a $1.3 million credit to customers associated with EDIT, and requesting to consolidate the two service areas into one. If approved, new rates are expected to become effective in the third quarter of 2020.

2020 FINANCIAL GUIDANCE

ONE Gas affirmed its 2020 financial guidance, with net income expected to be in the range of $186 million to $198 million, or $3.44 to $3.68 per diluted share.

Management expects a negative impact to earnings from lower revenues and net incremental expenses, including bad debt expenses, associated with the COVID-19 pandemic. This impact will be partially mitigated by regulatory assets established in accordance with the accounting orders that are expected to be received in all jurisdictions but could result in net income and diluted earnings per share below the midpoint of the guidance range.

NON-GAAP INFORMATION

ONE Gas has disclosed net margin in this news release, which is considered a non-GAAP financial metric used to measure the company's financial performance. Net margin is comprised of total revenues less cost of natural gas. Cost of natural gas includes commodity purchases, fuel, storage, transportation and other gas purchase costs recovered through our cost of natural gas regulatory mechanisms and does not include an allocation of general operating costs or depreciation and amortization. In addition, these regulatory mechanisms provide a method of recovering natural gas costs on an ongoing basis without a profit. Therefore, although our revenues will fluctuate with the cost of natural gas that we pass through to our customers, net margin is not affected by fluctuations in the cost of natural gas. Accordingly, we routinely use net margin in the analysis of our financial performance. We believe that net margin provides investors a more relevant and useful measure to analyze our financial performance as a 100% regulated natural gas utility than total revenues because the change in the cost of natural gas from period to period does not impact our operating income. A reconciliation of net margin to the most directly comparable GAAP measure is included as a table at the end of the earnings tables accompanying this release.

---------------------------------------------------------------------------------------------------------------------

• adverse labor relations;

• the effectiveness of our strategies to reduce earnings lag, margin protection strategies and risk mitigation strategies, which may be affected by risks beyond our control such as commodity price volatility and counterparty creditworthiness;
