Amounts for the year ended Dec. 31, 2022, include a $5 million property insurance deductible and an approximately $30 million earnings impact in the natural gas liquids segment from the 45-day waiting period for business interruption coverage related to the Medford incident, which together represent 6 cents per diluted share after tax. (b) Adjusted earnings before interest, taxes, depreciation and amortization (adjusted EBITDA) is a non-GAAP measure. A reconciliation to the relevant GAAP measure is included in this news release. HIGHLIGHTS: • In January 2023, ONEOK increased its quarterly dividend 2% to 95.5 cents per share, or $3.82 per share on an annualized basis. • Capital-growth projects: ◦ In December 2022, a ONEOK subsidiary filed a Presidential Permit application with the Federal Energy Regulatory Commission (FERC) to construct and operate new international border-crossing facilities at the U.S. and Mexico border. The proposed border facilities would connect upstream with a potential ONEOK intrastate natural gas pipeline, the Saguaro Connector Pipeline, and with a new pipeline under development in Mexico for delivery to an export facility on the west coast of Mexico. A final investment decision on the pipeline is expected in mid-2023. ◦ In January 2023, ONEOK announced plans to construct MB-6, a 125,000-barrel per day (bpd) NGL fractionator in Mont Belvieu, Texas, which is expected to be completed in the first quarter 2025.

&nbsp;&nbsp;&nbsp;&nbsp;ONEOK Announces 28% Increase in Fourth Quarter 2022 Net Income and 15% Increase in Full- year 2022 Net Income Feb. 27, 2023 Page 3 -more- ◦ In February 2023, ONEOK's 200 million cubic feet per day (MMcf/d) Demicks Lake III processing plant in the Williston Basin was completed. ◦ Construction of the 125,000 bpd MB-5 fractionator in Mont Belvieu, Texas, is expected to be completed early in the second quarter 2023. • In November 2022, ONEOK completed a $750 million senior notes offering due 2032 generating net proceeds of $742 million. • In February 2023, ONEOK redeemed $425 million of 5% senior notes due September 2023 with cash on hand. • In 2022, ONEOK received an MSCI ESG Rating of AAA, and received an ESG Risk Rating in the lowest-risk quintile of Sustainalytics' refiners and pipelines industry, indicating that ONEOK's ESG risk management is in the top 20% of its industry. FULL-YEAR 2022 FINANCIAL PERFORMANCE ONEOK reported full-year 2022 net income and adjusted earnings before interest, taxes, depreciation and amortization (adjusted EBITDA) of $1,722.2 million and $3,619.7 million, respectively. Higher 2022 results were driven primarily by increased producer activity across ONEOK's operations, higher realized commodity prices, higher average fee rates, and higher natural gas storage and transportation services. Results included higher operating costs due primarily to higher outside services, materials and supplies expenses, and higher property taxes, primarily related to the growth of ONEOK's operations. Net income for the period benefited from lower interest expense related to increased capitalized interest and lower debt balances, and higher equity in net earnings from investments. Medford Facility Incident Update In 2022, ONEOK recorded insurance accruals of $150.7 million related to the Medford incident, which fully offset the actual costs incurred following the company's 45-day waiting period for business interruption coverage and its $5.0 million property deductible. A summary of ONEOK's 2022 Medford insurance activity is provided in the table below: 2022 Insurance Accruals (Millions of dollars) Business interruption (a) $96.1 Noncash property losses 45.6 Medford response expenses 9.0 Total insurance recoveries accrued $150.7 Less: Cash received in 2022 $(100.0) Insurance receivable at Dec. 31, 2022 $50.7 (a) Amounts primarily represent third-party fractionation costs.

ONEOK received the remaining $830 million in the first quarter 2023 and applied $50.7 million to the outstanding 2022 receivable, recording a gain in operating income for the difference of $779.3 million in the first quarter 2023. 2023 GUIDANCE: 2023 Guidance Range (Millions of dollars, except per share amounts) ONEOK, Inc.

A reconciliation to the relevant GAAP measure is included in this news release. ONEOK's 2023 net income and adjusted EBITDA guidance include a total impact of $539.3 million related to the Medford incident, comprised of a one-time insurance settlement gain of $779.3 million partially offset by an estimated $240 million primarily related to third- party fractionation costs, which ONEOK expects to incur in 2023. Medford-related costs are expected to be meaningfully lower in 2024 due to ONEOK's ability to fully utilize the MB-5 fractionator to substantially reduce third-party fractionation costs compared with 2023. 2023 Guidance Range Summary of 2023 Volume Guidance Natural Gas Liquids Raw Feed Throughput (MBbl/d) 1,265 - 1,385 Natural Gas Processed (MMcf/d) 2,040 - 2,340

&nbsp;&nbsp;&nbsp;&nbsp;ONEOK Announces 28% Increase in Fourth Quarter 2022 Net Income and 15% Increase in Full- year 2022 Net Income Feb. 27, 2023 Page 6 -more- The increase in fourth quarter 2022 adjusted EBITDA, compared with the fourth quarter 2021, primarily reflects: • A $57.4 million increase in optimization and marketing due primarily to higher earnings on sales of purity NGLs held in inventory and wider location and commodity price differentials; offset by • A $9.7 million increase in operating costs due primarily to increased property taxes associated with ONEOK's completed capital-growth projects; and • A $3.3 million decrease in exchange services due primarily to narrower commodity price differentials and lower ethane volume in the Mid-Continent region, offset partially by higher average fee rates. The increase in adjusted EBITDA for the full year 2022, compared with 2021, primarily reflects: • A $102.8 million increase in exchange services (excluding the impact of Winter Storm Uri discussed below) due primarily to: ◦ $186.3 million in higher average fee rates, primarily as a result of inflation-based and fuel cost contract escalators, ◦ $50.1 million in higher volumes primarily in the Rocky Mountain region and Permian Basin, offset partially by lower volumes in the Mid-Continent region, offset by ◦ $129.9 million in higher costs, primarily related to fuel and power costs and higher third-party fractionation costs. A portion of the third-party fractionation costs relate to the 45-day business interruption coverage waiting period associated with the Medford incident, and ◦ $12.9 million related to recognition of proceeds previously considered a gain contingency in 2021; and • A $46.2 million increase in exchange services due to the unfavorable impact of Winter Storm Uri in the first quarter 2021; • An $18.2 million increase in optimization and marketing due primarily to wider location and commodity price differentials, offset partially by nonrecurring activities in the first quarter 2021 during Winter Storm Uri; and • A $13.6 million increase in equity in net earnings from investments due primarily to higher volumes delivered to the Overland Pass Pipeline; offset by • A $48.8 million increase in operating costs due primarily to higher property taxes associated with ONEOK's completed capital-growth projects and higher outside services expenses.

LINK TO EARNINGS TABLES AND PRESENTATION: https://ir.oneok.com/financial-information/financial-reports 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.
