Forward-Looking Statements

This communication contains “forward-looking statements” within the meaning of the federal securities laws, including Section 27A of the Securities Act and Section 21E of the Securities Exchange Act of 1934, as amended. In this context, forward-looking statements often address future business and financial events, conditions, expectations, plans or ambitions, and often include, but are not limited to, words such as “believe,” “expect,” “may,” “will,” “should,” “could,” “would,” “anticipate,” “estimate,” “intend,” “plan,” “seek,” “see,” “target” or similar expressions, or variations or negatives of these words, but not all forward-looking statements include such words. Forward-looking statements by their nature address matters that are, to different degrees, uncertain, such as statements about the consummation of the proposed transaction and the anticipated benefits thereof. All such forward-looking statements are based upon current plans, estimates, expectations and ambitions that are subject to risks, uncertainties and assumptions, many of which are beyond the control of Energy Transfer and Crestwood, that could cause actual results to differ materially from those expressed in such forward-looking statements. Important risk factors that may cause such a difference include, but are not limited to: the completion of the proposed transaction on anticipated terms and timing, or at all, including obtaining Crestwood unitholder approval and any other approvals that may be required on anticipated terms; anticipated tax treatment, unforeseen liabilities, future capital expenditures, revenues, expenses, earnings, synergies, economic performance, indebtedness, financial condition, losses, future prospects, business and management strategies for the management, expansion and growth of the combined company’s operations and other conditions to the completion of the merger, including the possibility that any of the anticipated benefits of the proposed transaction will not be realized or will not be realized within the expected time period; the ability of Energy Transfer and Crestwood to integrate the business successfully and to achieve anticipated synergies and value creation; potential litigation relating to the proposed transaction that could be instituted against Energy Transfer, Crestwood or the directors of their respective general partners; the risk that disruptions from the proposed transaction will harm Energy Transfer’s or Crestwood’s business, including current plans and operations and that management’s time and attention will be diverted on transaction-related issues; potential adverse reactions or changes to business relationships, including with employees suppliers, customers, competitors or credit rating agencies, resulting from the announcement or completion of the proposed transaction; rating agency actions and Energy Transfer and Crestwood’s ability to access short- and long-term debt markets on a timely and affordable basis; legislative, regulatory and economic developments, changes in local, national, or international laws, regulations, and policies affecting Energy Transfer and Crestwood; potential business uncertainty, including the outcome of commercial negotiations and changes to existing business relationships during the pendency of the proposed transaction that could affect Energy Transfer’s and/or Crestwood’s financial performance and operating results; certain restrictions during the pendency of the merger that may impact Crestwood’s ability to pursue certain business opportunities or strategic transactions or otherwise operate its business; acts of terrorism or outbreak of war, hostilities, civil unrest, attacks against Energy Transfer or Crestwood, and other political or security disturbances; dilution caused by Energy Transfer’s issuance of additional units representing limited partner interests in connection with the proposed transaction; the possibility that the transaction may be more expensive to complete than anticipated, including as a result of unexpected factors or events; the impacts of pandemics or other public health crises, including the effects of government responses on people and economies; changes in the supply, demand or price of oil, natural gas, and natural gas liquids; those risks described in Item 1A of Energy Transfer’s Annual Report on Form 10-K, filed with the SEC on February 17, 2023, and its subsequent Quarterly Reports on Form 10 Q and Current Reports on Form 8-K; those risks described in Item 1A of Crestwood’s Annual Report on Form 10-K, filed with the SEC on February 27, 2023, and its subsequent Quarterly Reports on Form 10-Q and Current Reports on Form 8-K; and those risks that are described in the Registration Statement and the accompanying proxy statement/prospectus filed with the SEC in connection with the proposed transaction.

While the list of factors presented here, in the Registration Statement and in the proxy statement/prospectus is considered representative, no such list should be considered to be a complete statement of all potential risks and uncertainties. Unlisted factors may present significant additional obstacles to the realization of forward-looking statements.

Neither Energy Transfer nor Crestwood assumes any obligation to publicly provide revisions or updates to any forward-looking statements, whether as a result of new information, future developments or otherwise, should circumstances change, except as otherwise required by securities and other applicable laws.
