Item 7.01Regulation FD Disclosure
On March 1, 2024, ONE Gas, Inc. (NYSE: OGS) announced that its Kansas Gas Service division filed a request with the Kansas Corporation Commission (KCC) for an increase in its rates to recover the investments made to maintain a safe, reliable, and environmentally responsible natural gas distribution system across Kansas. A copy of the news release is attached as Exhibit 99.1 and is incorporated herein by reference.

The information disclosed in Item 7.01, including Exhibit 99.1 hereto, is being furnished and shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the Exchange Act), or otherwise subject to the liabilities under that section, nor shall it be deemed incorporated by reference in any filing under the Securities Act of 1933, as amended, or the Exchange Act except as expressly set forth by specific reference in such filing.
Item 8.01Other Events
ONE Gas, Inc. announced today that its Kansas Gas Service division filed a request with the KCC to increase its net base rates by $58 million. Since its last base rate case finalized in February 2019, Kansas Gas Service has invested over $600 million in its natural gas distribution system. Through the Gas System Reliability Surcharge (GSRS), existing rates include $297 million of the $600 million.

Kansas Gas Service’s request, if approved, represents a net rate increase of $58 million. Kansas Gas Service is already recovering $35 million from customers through the GSRS, resulting in a total base rate increase of $93 million.

Kansas Gas Service’s request also proposes new residential rate options that align with the energy used and give customers more control of their bills. If approved, the average monthly residential bill will increase by approximately $6.71 for customers who typically use less natural gas and $9.48 for those who use more natural gas.

The company’s filing also includes a proposed annual performance-based rate adjustment mechanism that would review rates annually to address investments and changes in operating expenses necessary to maintain safe and reliable service.

The filing is based on a 10.25 percent return on equity and a 59.6 percent common equity ratio.
The filing represents a rate base of $1.4 billion, compared with $1.3 billion included in existing base rates plus previously approved GSRS-eligible investments.

The portion of the bill associated with the cost of gas, which represented 52 percent of the average residential bill in 2023, is not impacted by this filing. The cost of gas continues to be passed through to customers with no markup.

In accordance with Kansas law, the KCC has 240 days to consider Kansas Gas Service’s filing.

Kansas Gas Service Prioritizes Safety and Reliability
in Rate Review Request

OVERLAND PARK, Kan. – March 1, 2024 – Kansas Gas Service, a division of ONE Gas, Inc., announced today that it has filed a request with the Kansas Corporation Commission (KCC) to increase its rates to recover the investments made to maintain a safe, reliable and environmentally responsible natural gas distribution system across Kansas.

"We’re committed to safety, improving our system and the reliable delivery of natural gas, even in challenging weather like Winter Storm Uri in 2021 and Winter Storm Gerri this past January," said Sean Postlethwait, vice president of operations for Kansas Gas Service. “During these extraordinary winter events, our team worked around the clock to provide reliable natural gas service to more than 647,000 customer homes and businesses in 360 communities across Kansas.”

The filing includes an increase in net base rates of $58 million. It also proposes new residential rate options that align with the energy used and give customers more control of their bills. If approved, the average monthly residential bill will increase by approximately $6.71 for customers who use less natural gas and $9.48 for those who use more natural gas.

This filing does not impact the portion of the bill associated with the cost of gas, which represented 52% of the average residential bill in 2023. The cost of gas continues to be competitively bid and then passed through to customers with no markup.

In Kansas, natural gas maintains a sizable cost advantage of approximately 3-to-1 when comparing electricity's average price and equivalent energy value to natural gas. Lower energy costs mean families have more money to meet their everyday needs.

"Our employees work hard to manage our expenses to help keep energy costs at reasonable rates,” continued Postlethwait. “We are here to assist our customers with programs to manage their monthly bills and provide helpful energy-saving tools."

In accordance with Kansas law, the KCC has 240 days to consider Kansas Gas Service’s filing. For additional information about the filing, helpful energy-saving tips and payment options available, visit kansasgasservice.com/ratecase.
