ONEOK Announces 14% Year-Over-Year Increase in Third Quarter 2020 Operating Income Oct. 27, 2020 Page 2 “Third quarter results were driven by curtailed volume returning to our system resulting in improved earnings,” said Terry K. Spencer, ONEOK president and chief executive officer. “NGL volumes across all of our operating areas have exceeded pre-pandemic levels, and natural gas volumes processed in the Rocky Mountain region have exceeded 1.2 billion cubic feet per day. Volumes achieved in September were more in-line with our original pre-pandemic 2020 expectations. “We remain focused on operating safely and environmentally responsibly,” said Spencer. “Reliable service and value creation continue to guide our strategy as we evaluate the opportunities ahead of us.” THIRD QUARTER 2020 FINANCIAL PERFORMANCE Three Months Ended Nine Months Ended September 30, September 30, 2020 2019 2020 2019 (Millions of dollars, except per share and dividend coverage ratio amounts) Net income (a) $ 312.3 $ 309.2 $ 304.8 $ 958.3 Net income per diluted share (a) $ 0.70 $ 0.74 $ 0.71 $ 2.31 Adjusted EBITDA (b) (c) $ 747.0 $ 649.8 $ 1,981.7 $ 1,919.7 DCF (b) $ 540.9 $ 480.9 $ 1,363.8 $ 1,528.2 DCF in excess of dividends paid (b) $ 125.3 $ 113.0 $ 174.2 $ 448.8 Dividend coverage ratio (b) 1.30 1.31 1.15 1.42 Operating income (d) $ 550.4 $ 482.2 $ 822.7 $ 1,427.0 Operating costs $ 205.0 $ 245.1 $ 636.5 $ 723.6 Depreciation and amortization $ 153.2 $ 121.4 $ 426.0 $ 350.6 Equity in net earnings from investments $ 38.0 $ 37.6 $ 108.0 $ 115.2 Capital expenditures $ 380.0 $ 1,019.2 $ 1,924.0 $ 2,739.3 (a) Amounts for the three and nine months ended Sept. 30, 2020, include benefits of $2.2 million and $22.2 million, respectively, related to gains on open market repurchases of debt.

ONEOK’s operating income and adjusted EBITDA increased 14% and 15%, respectively, compared with the third quarter 2019. Higher results were driven primarily by increased NGL volumes across ONEOK’s operations, lower operating costs in all three of ONEOK’s business segments, and lower rail transportation and pipeline costs in the natural gas liquids segment due to the completion of ONEOK’s Elk Creek Pipeline, compared with the third quarter 2019. -more-

ONEOK Announces 14% Year-Over-Year Increase in Third Quarter 2020 Operating Income Oct. 27, 2020 Page 3 Results were partially offset by higher depreciation expense due to capital-growth projects placed in service, lower earnings from optimization and marketing in the natural gas liquids segment, lower natural gas volumes in the natural gas gathering and processing segment due to natural production declines in the Mid-Continent region and production curtailments in the Williston Basin, and lower interruptible transportation services in the natural gas pipelines segment, compared with the third quarter 2019. HIGHLIGHTS: • Third quarter adjusted EBITDA of $747.0 million, a 40% increase compared with the second quarter 2020 and a 7% increase compared with the first quarter 2020; • NGL projects completed in August 2020: ◦ The 75-mile Bakken NGL pipeline lateral connecting to a third-party natural gas processing plant in Williams County, North Dakota; and ◦ The Arbuckle II pipeline extension which increases connectivity from the Elk Creek Pipeline to the Arbuckle II Pipeline and additional Mid-Continent NGL gathering infrastructure. • Substantially completing all active announced capital-growth projects and maintaining an annual run rate of $300 million to $400 million of total capital expenditures until producer activity levels warrant additional infrastructure; • ESG highlights: ◦ Recognized as the industry leader in Energy Equipment & Services for the second year in a row by JUST Capital, an organization that ranks companies at the forefront of stakeholder-driven leadership; and ◦ Recipient of the 2020 Frank Condon Award for Environmental Excellence by the Environmental Federation of Oklahoma. • Declaring in October 2020 a quarterly dividend of 93.5 cents per share, or $3.74 per share on an annualized basis; • Net debt-to-EBITDA ratio of 4.6 times on an annualized run-rate basis as of Sept. 30, 2020; and • Having no borrowings outstanding under its $2.5 billion credit agreement and $447.1 million of cash and cash equivalents as of Sept. 30, 2020. BUSINESS-SEGMENT RESULTS: Natural Gas Liquids Segment The natural gas liquids segment’s third quarter 2020 adjusted EBITDA increased 23%, compared with the same period in 2019, due primarily to higher volumes across ONEOK’s operations and lower rail transportation and pipeline costs compared with the third quarter 2019.

These non-GAAP financial measures described above are useful to investors because they, and similar measures, are used by many companies in the industry as a measure of financial performance and are commonly employed by financial analysts and others to evaluate our financial performance and to compare our financial performance with the performance of other companies within our industry. Adjusted EBITDA, ONEOK distributable cash flow and dividend coverage ratio 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. -more-
