As previously announced, on May 14, 2023, Magellan Midstream Partners, L.P. (NYSE: MMP), a Delaware limited partnership (“Magellan”), entered into an Agreement and Plan of Merger (the “Merger Agreement”) with ONEOK, Inc., an Oklahoma corporation (NYSE: ONEOK) (“ONEOK”), and Otter Merger Sub, LLC, a Delaware limited liability company and a newly formed, wholly owned subsidiary of ONEOK (“Merger Sub”), pursuant to which, upon the terms and subject to the conditions of the Merger Agreement, Merger Sub will merge with and into Magellan (the “Merger”), with Magellan continuing as the surviving entity and a wholly owned subsidiary of ONEOK.

On ~~September 11~~June 20, 2023, ~~Magellan~~ONEOK ~~issued~~filed a ~~press~~registration ~~release~~statement ~~announcing~~on ~~that~~Form ~~its~~S-4 ~~board~~(No. of333-272758) ~~directors~~(the ~~has~~“Registration ~~declared~~Statement”), which contained a ~~special~~preliminary ~~cash~~prospectus ~~distribution~~of ~~payable on~~ONEOK ~~September~~and ~~25,~~a ~~2023~~preliminary tojoint ~~unitholders~~proxy statement of ~~record~~Magellan atand ONEOK. The Registration Statement was declared effective by the ~~close~~Securities ofand ~~business~~Exchange Commission (the “SEC”) on ~~September~~July 2124, 2023, which Registration Statement contained ONEOK’s definitive prospectus and Magellan’s and ONEOK’s definitive joint proxy statement (the “joint proxy statement/prospectus” or the “Proxy Statement”). AMagellan ~~copy~~filed ofwith the ~~press~~SEC ~~release~~the isjoint ~~attached~~proxy statement/prospectus ~~hereto~~with asthe ~~Exhibit~~SEC ~~99.1~~on July 25, 2023 and iscommenced ~~incorporated~~mailing ~~herein~~copies byof ~~reference~~the Proxy Statement on or about July 25, 2023.

~~Cautionary~~Following ~~Statement~~the ~~Regarding~~entry ~~Forward~~into the Merger Agreement, six lawsuits have been filed by purported unitholders of Magellan related to the Merger: Gerald Joseph Lovoi v. Magellan Midstream Partners, L.P., et al., No. 23-~~Looking~~cv-06452 ~~Statements~~(S.D.N.Y. July 26, 2023); Ryan O’Dell v. Magellan Midstream Partners, L.P., et al., No. 23-cv-06679 (S.D.N.Y. July 31, 2023); Phil Lifschitz v. Magellan Midstream Partners, L.P., et al., No. 23-cv-06858 (S.D.N.Y. August 4, 2023); John McDaniels v.

Each of the Unitholder Actions asserts that certain allegedly material omissions in the joint proxy statement/prospectus purportedly give rise to violations of Section 14(a) of the Securities and Exchange Act of 1934, as amended (“Exchange Act”), Rule 14a-9 promulgated thereunder, and Section 20(a) of the Exchange Act. Each of the Unitholder Actions seek, among other relief, an order preliminarily and permanently enjoining the Merger.

~~This~~Additionally, ~~report~~following ~~contains “forward-looking statements” within~~ the ~~meaning~~entry ofinto ~~Section 27A of~~ the ~~Securities~~Merger ~~Act of 1933~~Agreement, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. All statements, other than statements of historical fact, included in this report that address activities, events or developments that ONEOK or Magellan ~~expects,~~received ~~believes~~ten ordemand ~~anticipates~~letters ~~will or may occur in~~ (the ~~future are forward-looking statements.

There are a number of risks and uncertainties~~ that could cause actual results to differ materially from the forward-looking statements included in this report. These include the risk that ONEOK’s and Magellan’s businesses will not be integrated successfully; the risk that cost savingsadditional, ~~synergies and growth from the Merger may not be fully realized~~ or ~~may~~similar ~~take~~demand ~~longer~~letters ~~to realize than expected; the risk that the credit ratings of the combined company or its subsidiaries~~ may be ~~different~~received ~~from~~by ~~what~~Magellan, ~~the companies expect; the possibility that shareholders of ONEOK may not approve the issuance of new shares of ONEOK common stock in the Merger~~ or that ~~unitholders of Magellan~~complaints ~~may~~making ~~not~~similar ~~approve~~allegations ~~the Merger; the risk that a condition~~ to ~~closing of~~ the ~~Merger~~Unitholder ~~may~~Actions ~~not be satisfied, that either party~~ may ~~terminate the Merger Agreement or that the closing of the Merger might~~ be ~~delayed or not occur at all; potential adverse reactions or changes to business or employee relationships~~filed, ~~including~~regarding ~~those resulting from~~ the ~~announcement or completion of the~~ Merger;. ~~the~~Absent ~~occurrence~~new ~~of any other event, change~~ or ~~other~~different ~~circumstances~~allegations that ~~could give rise to the termination of the Merger Agreement relating to the Merger; the~~are ~~risk~~material that changes in ONEOK’s capital structure and governance could have adverse effects on the market value of its securities; the ability of ONEOK and Magellan to retain customers and retain and hire key personnel and maintain relationships with their suppliers and customers and on ONEOK’s and Magellan’s operating results and business generally; the risk the Merger could distract management from ongoing business operations or cause ONEOK and/or Magellan to incur substantial costs; the risk of any litigation relating to the Merger; the risk that ONEOK may be unable to reduce expenses or access financing or liquidity; the impact of a ~~pandemic,~~disclosure ~~any~~obligation ~~related economic~~under ~~downturn and any related substantial decline in commodity prices;~~ the risk of changes in governmental regulations or enforcement practices, especially with respect to environmental, health and safety matters; and other important factors that could cause actual results to differ materially from those projectedU.S. ~~All~~federal ~~such~~securities ~~factors are difficult to predict and are beyond ONEOK’s or Magellan’s control~~laws, ~~including those detailed in the joint proxy statement/prospectus (as defined below). All forward-looking statements are based on assumptions that ONEOK and~~ Magellan ~~believe~~will ~~to be reasonable but that may~~ not ~~prove~~necessarily todisclose ~~be accurate. Any forward-looking statement speaks only as of the date on which~~ such ~~statement~~additional ~~is made, and neither ONEOK nor Magellan undertakes any obligation to correct or update~~demands ~~any forward-looking statement, whether as a result of new information, future events~~ or ~~otherwise, except as required by applicable law~~complaints. ~~Readers are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date hereof.~~

Magellan believes that the disclosures set forth in the joint proxy statement/prospectus comply fully with applicable law, that no further disclosure beyond that already contained in the joint proxy statement/prospectus is required under applicable law, and that the allegations asserted in both the Unitholder Actions and Demand Letters are entirely without merit. However, in order to moot these disclosure claims, to avoid nuisance, cost and distraction, and to preclude any efforts to delay the closing of the Merger, and without admitting any liability or wrongdoing, Magellan is voluntarily supplementing the joint proxy statement/prospectus with the supplemental disclosures set forth below (the “Supplemental Disclosures”). Nothing in the Supplemental Disclosures shall be deemed an admission of the legal necessity or materiality under applicable laws of any of the disclosures set forth herein. To the contrary, Magellan specifically denies all allegations in the Unitholder Actions and Demand Letters that any additional disclosure was or is required.

(1)

The Magellan Forecasted Financial Information set forth in this table does not take into account any circumstances or events occurring after the date it was prepared. Given that the Magellan Special Meeting and ONEOK Special Meeting will be held several months after the Magellan Forecasted Financial Information was prepared, as well as the uncertainties inherent in any forecasted information, Magellan unitholders and ONEOK shareholders are cautioned not to place undue reliance on such information.

(2)

Adjusted EBITDA is defined as net income adjusted for interest expense, depreciation and amortization, noncash impairment, equity based incentive compensation, commodity related adjustments, derivative losses associated with future transactions, gain on the disposition of Magellan assets and distributions from non-controlled entities in excess of earnings.

Free Cash Flow is defined as Adjusted EBITDA less interest expense, maintenance capex and growth capex, plus proceeds from asset sales. Adjusted Free Cash Flow After Distributions is defined as Free Cash Flow less distributions. Free Cash Flow and Adjusted Free Cash Flow After Distributions are not measures of financial performance under GAAP. Accordingly, they should not be considered as a substitute for net income (loss), operating income (loss) or other measures prepared in accordance with GAAP.

(4)	Assumes distributions paid will be $849 million, $836 million, $821 million, $804 million and $784 million for 2023E, 2024E, 2025E, 2026E and 2027E, respectively.

(45)

Unlevered Free Cash Flow, as used by Magellan’s financial advisor, as instructed by Magellan, is defined as Adjusted EBITDA, less stock-based compensation, maintenance capex and growth capex and change in net working capital, plus proceeds from asset sales. Unlevered Free Cash Flow is not a measure of financial performance under GAAP. Accordingly, it should not be considered as a substitute for net income (loss), operating income (loss) or other measures prepared in accordance with GAAP.

(56)

Unlevered Free Cash Flow, as used by ONEOK’s financial advisor, as instructed by ONEOK, is defined as Adjusted EBITDA, less maintenance capex and growth capex plus proceeds from asset sales. Unlevered Free Cash Flow is not a measure of financial performance under GAAP. Accordingly, it should not be considered as a substitute for net income (loss), operating income (loss) or other measures prepared in accordance with GAAP.

The section of the joint proxy statement/prospectus entitled “Analyses Related to Magellan” is amended and supplemented as follows:

The second paragraph below the subheading “Discounted Equity Value Analysis” starting on page 87 of the joint proxy statement/prospectus is amended and restated as follows:

To calculate the discounted equity value for Magellan, Morgan Stanley utilized estimated calendar year 2025 adjusted EBITDA based on the Magellan Management Projections. Based upon the application of its professional judgment and experience after reviewing and comparing certain financial estimates for Magellan, Morgan Stanley applied a range of multiples of AV/NTM EBITDA for the 12-month period following January 1, 2025 of 9.5x to 11.5x to these estimates, which range was selected based upon Morgan Stanley’s professional judgment and experience taking into account, among other factors, the multiple range for the comparable companies and Magellan’s historical long-term trading multiples, and discounted the resulting values to March 31, 2023 at a discount rate of 7.8% based on Morgan Stanley’s estimate of Magellan’s then-current cost of equity using the capital asset pricing model, which takes into account market risk premium, risk-free rate, a beta of the underlying stock and a sensitivity adjustment to derive the applicable range.

The first paragraph below the subheading “Discounted Cash Flow Analysis” on page 88 of the joint proxy statement/prospectus is amended and restated as follows:

Morgan Stanley performed a discounted cash flow analysis, which is designed to provide an implied value of a company by calculating the present value of the estimated future unlevered free cash flows and terminal value of such company. Morgan Stanley calculated a range of implied equity values per Magellan Unit as of March 31, 2023, based on estimates of future unlevered free cash flows for the nine months ending December 31, 2023 and fiscal years 2024 through 2027 contained in the Magellan Management Projections, including net debt of Magellan as of March 31, 2023 of $4,993 million. Morgan Stanley also calculated a range of terminal values for Magellan based on a NTM EBITDA exit multiple range of 9.5x to 11.5x, which was selected based on Morgan Stanley’s professional judgment and experience, and taking into account, among other factors, the multiple range for the comparable companies. The estimated unlevered free cash flows and the range of terminal values were then discounted to present value as of March 31, 2023 using mid-year convention (except for terminal value which was discounted using end-of-period methodology) by applying a discount rate of 6.8%, which was selected based on, upon the application of Morgan Stanley’s professional judgment and experience, to reflect Magellan’s estimated weighted average cost of capital (“WACC”), utilizing the capital asset pricing model to calculate Magellan’s cost of equity and the current blended interest rate on Magellan’s outstanding debt for the cost of debt.

The disclosure on page 88 of the joint proxy statement/prospectus below the subheading “Other Factors” is amended and supplemented by adding the following sentence and chart to the end of the second bullet point as follows:

To calculate the discounted equity value for ONEOK, Morgan Stanley utilized estimated calendar year 2025 EBITDA based on the ONEOK Management Projections. Based upon the application of its professional judgment and experience after reviewing and comparing certain financial estimates for ONEOK, Morgan Stanley applied a range of multiples of NTM AV/EBITDA for the 12-month period following January 1, 2025 of 9.5x to 11.5x to these estimates, which range was selected based upon Morgan Stanley’s professional judgment and experience taking into account, among other factors, the multiple range for the comparable companies and ONEOK’s historical long-term trading multiples, and discounted the resulting values to March 31, 2023 at a discount rate of 9.0% based on Morgan Stanley’s estimate of ONEOK’s then-current cost of equity using the capital asset pricing model, which takes into account market risk premium, risk-free rate, a beta of the underlying stock and a sensitivity adjustment to derive the applicable range.

The first paragraph below the subheading “Discounted Cash Flow Analysis” on page 91 of the joint proxy statement/prospectus is amended and restated as follows:

Morgan Stanley performed a discounted cash flow analysis, which is designed to provide an implied value of a company by calculating the present value of the estimated future unlevered free cash flows and terminal value of such company. Morgan Stanley calculated a range of implied equity values per share of ONEOK Common Stock as of March 31, 2023, based on estimates of future unlevered free cash flows for the nine months ending December 31, 2023 and fiscal years 2024 through 2027 contained in the ONEOK Management Projections, including net debt of ONEOK as of March 31, 2023 of $12,676 million.

The estimated unlevered free cash flows and the range of terminal values were then discounted to present value as of March 31, 2023 by applying a discount rate of 7.3%, which was selected based on, upon the application of Morgan Stanley’s professional judgment and experience, to reflect ONEOK’s estimated WACC, utilizing the capital asset pricing model to calculate ONEOK’s cost of equity and the current blended interest rate on ONEOK’s outstanding debt for the cost of debt.

Magellan has also agreed to reimburse Morgan Stanley for certain of its expenses incurred in performing its services, including fees and expenses of outside counsel to Morgan Stanley. In addition, Magellan has agreed to indemnify Morgan Stanley and its affiliates, their respective directors, officers, agents and employees and each person, if any, controlling Morgan Stanley or any of its affiliates against certain liabilities and expenses, including certain liabilities under the federal securities laws, related to or arising out of Morgan Stanley’s engagement.

Cautionary Statement Regarding Forward-Looking Statements

This report contains “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. All statements, other than statements of historical fact, included in this report that address activities, events or developments that ONEOK or Magellan expects, believes or anticipates will or may occur in the future are forward-looking statements. Words such as “estimate,” “project,” “predict,” “believe,” “expect,” “anticipate,” “potential,” “create,” “intend,” “could,” “would,” “may,” “plan,” “will,” “guidance,” “look,” “goal,” “future,” “build,” “focus,” “continue,” “strive,” “allow” or the negative of such terms or other variations thereof and words and terms of similar substance used in connection with any discussion of future plans, actions, or events identify forward-looking statements. However, the absence of these words does not mean that the statements are not forward-looking. These forward-looking statements include, but are not limited to, statements regarding the Merger, the expected closing of the Merger and the timing thereof and as adjusted descriptions of the post-transaction company and its operations, strategies and plans, integration, debt levels and leverage ratio, capital expenditures, cash flows and anticipated uses thereof, synergies, opportunities and anticipated future performance, including maintaining current ONEOK management, enhancements to investment-grade credit profile, an expected accretion to earnings and free cash flow, dividend payments and potential share repurchases, increase in value of tax attributes and expected impact on EBITDA. Information adjusted for the Merger should not be considered a forecast of future results. There are a number of risks and uncertainties that could cause actual results to differ materially from the forward-looking statements included in this report. These include the risk that ONEOK’s and Magellan’s businesses will not be integrated successfully; the risk that cost savings, synergies and growth from the Merger may not be fully realized or may take longer to realize than expected; the risk that the credit ratings of the combined company or its subsidiaries may be different from what the companies expect; the possibility that shareholders of ONEOK may not approve the issuance of new shares of ONEOK common stock in the Merger or that unitholders of Magellan may not approve the Merger; the risk that a condition to closing of the Merger may not be satisfied, that either party may terminate the Merger Agreement or that the closing of the Merger might be delayed or not occur at all; potential adverse reactions or changes to business or employee relationships, including those resulting from the announcement or completion of the Merger; the occurrence of any other event, change or other circumstances that could give rise to the termination of the Merger Agreement relating to the Merger; the risk that changes in ONEOK’s capital structure and governance could have adverse effects on the market value of its securities; the ability of ONEOK and Magellan to retain customers and retain and hire key personnel and maintain relationships with their suppliers and customers and on ONEOK’s and Magellan’s operating results and business generally; the risk the Merger could distract management from ongoing business operations or cause ONEOK and/or Magellan to incur substantial costs; the risk of any litigation relating to the Merger; the risk that ONEOK may be unable to reduce expenses or access financing or liquidity; the impact of a pandemic, any related economic downturn and any related substantial decline in commodity prices; the risk of changes in governmental regulations or enforcement practices, especially with respect to environmental, health and safety matters; and other important factors that could cause actual results to differ materially from those projected. All such factors are difficult to predict and are beyond ONEOK’s or Magellan’s control, including those detailed in the joint proxy statement/prospectus (as defined below). All forward-looking statements are based on assumptions that ONEOK and Magellan believe to be reasonable but that may not prove to be accurate. Any forward-looking statement speaks only as of the date on which such statement is made, and neither ONEOK nor Magellan undertakes any obligation to correct or update any forward-looking statement, whether as a result of new information, future events or otherwise, except as required by applicable law. Readers are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date hereof.
