Adjusted earnings before interest, taxes, depreciation and amortization (adjusted EBITDA) guidance increased to a range of $6.20 billion to $6.35 billion, compared with ONEOK's previous range of $6.025 billion to $6.325 billion. These midpoints and ranges exclude the contribution from ONEOK’s acquisition of the controlling interest in EnLink, the pending acquisition of Medallion and related transaction costs, to be comparable with ONEOK’s guidance provided on April 30, 2024.

Total 2024 stand-alone capital expenditure guidance remains unchanged at $1.75 billion to $1.95 billion. "ONEOK delivered solid results in the third quarter, supported by continued Rocky Mountain region strength, record refined products volumes, increased demand for natural gas transportation services and acquisition-related synergies," said Pierce H. Norton II, ONEOK president and chief executive officer. “Our ability to continue delivering on synergy opportunities through asset integration and connectivity efforts, coupled with strong fee-based earnings, drove ONEOK’s second financial guidance increase in 2024,” added Norton. “This combination of value creation through new and existing platforms demonstrates the strength of ONEOK’s integrated system and continued commitment to delivering exceptional value.”

ONEOK Announces Higher Third Quarter 2024 Earnings; Increases 2024 Financial Guidance Oct. 29, 2024 Page 5 -more- The increase in third quarter 2024 adjusted EBITDA, compared with the third quarter 2023, primarily reflects: • A $36 million increase in exchange services due primarily to higher volumes and higher average fee rates in the Rocky Mountain region, offset partially by lower volumes in the Mid-Continent region, primarily ethane, and higher transportation costs; • An $18 million increase related to the Medford incident due to lower third-party fractionation costs in the current quarter; and • A $7 million increase in adjusted EBITDA from unconsolidated affiliates due primarily to higher volumes delivered to the Overland Pass Pipeline; offset by • A $45 million decrease in optimization and marketing due primarily to lower earnings on sales of purity NGLs held in inventory.

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), 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, and other noncash items; and includes adjusted EBITDA from the company’s unconsolidated affiliates using the same recognition and measurement methods used to record equity in net earnings of unconsolidated affiliates. Adjusted EBITDA from unconsolidated affiliates is calculated consistently with the definition above and

ONEOK Announces Higher Third Quarter 2024 Earnings; Increases 2024 Financial Guidance Oct. 29, 2024 Page 8 -more- excludes items such as interest expense, depreciation and amortization, income taxes and other noncash items. Adjusted EBITDA is useful to investors because it and similar measures are 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. This news release includes or references certain forward-looking, non-GAAP financial measures. Because ONEOK provides these measures on a forward-looking basis, it can not reasonably predict certain of the necessary components of the most directly comparable forward- looking GAAP financial measures, such as future depreciation, JV EBITDA and other noncash items. Accordingly, ONEOK is unable to present a quantitative reconciliation of such forward- looking, non-GAAP financial measures to the respective most directly comparable forward- looking GAAP financial measure. ONEOK believes that these forward-looking, non-GAAP measures may be a useful tool for the investment community in comparing ONEOK’s forecasted financial performance to the forecasted financial performance of other companies in the industry.
