SECOND QUARTER 2022 FINANCIAL PERFORMANCE ONEOK’s second quarter 2022 net income and adjusted earnings before interest, taxes, depreciation and amortization (adjusted EBITDA) increased 21% and 11%, respectively, compared with the second quarter 2021. Results benefited from higher average fee rates and increased volumes in the natural gas liquids segment, higher realized commodity prices in the natural gas gathering and processing segment and increased storage services in the natural gas pipelines segment. Net income for the period also benefited from lower interest expense primarily related to lower debt balances and increased capitalized interest. Second quarter results were impacted by severe weather in the Rocky Mountain region in April 2022, resulting in power outages impacting natural gas and natural gas liquids (NGL) volumes from the region. By the end of May 2022, volumes approached pre-outage levels. HIGHLIGHTS: • Second quarter 2022 net income of $414.4 million, a 21% increase compared with the second quarter 2021. • Second quarter 2022 adjusted EBITDA of $886.0 million, an 11% increase compared with the second quarter 2021. • In July 2022, ONEOK declared a quarterly dividend of 93.5 cents per share, or $3.74 per share on an annualized basis. • In July 2022, ONEOK redeemed the remaining $895.8 million of 3.375% senior notes due October 2022.

Medford Facility Incident Update ONEOK’s 210,000 barrel per day (bpd) Medford, Oklahoma, NGL fractionation facility remains out of service following a fire on July 9, 2022. All personnel are safe and accounted for. ONEOK continues efforts to determine the cause of the event and expects the facility to remain out of service for an extended period of time. As a result of insurance coverage, ONEOK does not currently anticipate that the Medford incident will have a material effect on the company’s financial condition, results of operations or cash flows. However, the timing of insurance proceeds may impact financial results in a given quarter or year.

LINK TO EARNINGS TABLES AND PRESENTATION: https://ir.oneok.com/financial-information/financial-reports/2022 NON-GAAP (GENERALLY ACCEPTED ACCOUNTING PRINCIPLES) FINANCIAL MEASURES: ONEOK has disclosed in this news release adjusted earnings before interest, taxes, depreciation and amortization (adjusted EBITDA), which is a non-GAAP financial metric, used to measure the company’s financial performance. Adjusted EBITDA is defined as net income adjusted for interest expense, depreciation and amortization, noncash impairment charges, income taxes, noncash compensation expense, allowance for equity funds used during construction (equity AFUDC), and other noncash items. Adjusted EBITDA is useful to investors because it, and similar measures, is used by many companies in the industry as a measure of financial performance and is commonly employed by financial analysts and others to evaluate ONEOK’s financial performance and to compare the company’s financial performance with the performance of other companies within the industry. Adjusted EBITDA should not be considered in isolation or as a substitute for net income or any other measure of financial performance presented in accordance with GAAP. This non-GAAP financial measure excludes some, but not all, items that affect net income. Additionally, this calculation may not be comparable with similarly titled measures of other companies. A reconciliation of net income to adjusted EBITDA is included in the tables. ONEOK, Inc. (pronounced ONE-OAK) (NYSE: OKE) is a leading midstream service provider and owner of one of the nation's premier natural gas liquids (NGL) systems, connecting NGL supply in the Rocky Mountain, Mid-Continent and Permian regions with key market centers and an extensive network of natural gas gathering, processing, storage and transportation assets.
