As to any pro forma financial information to be included or incorporated by reference in the Registration Statement, the Pricing Disclosure Package and the Prospectus, the assumptions used in preparing such pro forma financial statements provide a reasonable basis for presenting the significant effects directly attributable to the transactions or events described therein, the related pro forma adjustments give appropriate effect to those assumptions, and the pro forma columns therein reflect the proper application of those adjustments to the corresponding historical financial statement amounts in the pro forma financial statements included or incorporated by reference in the Registration Statement, the Pricing Disclosure Package and the Prospectus. The pro forma financial statements included or incorporated by

reference in the Registration Statement, the Pricing Disclosure Package and the Registration Statement comply as to form in all material respects with the applicable accounting requirements under Regulation S-X and Regulation G. There are no financial statements (historical or pro forma) that are required to be included or incorporated by reference in the Registration Statement or the Prospectus that are not so included or incorporated by reference as required. The interactive data in eXtensible Business Reporting Language (“XBRL”) included or incorporated by reference in the Registration Statement, the Pricing Disclosure Package and the Prospectus fairly presents the information called for in all material respects and was prepared in accordance with the Commission’s rules and guidelines applicable thereto.

(ee) Independent Registered Public Accounting Firm. Grant Thornton LLP (“Grant Thornton”), who has certified certain financial statements of the Partnership and its Subsidiaries, whose reports are included or incorporated by reference in the Registration Statement, the Pricing Disclosure Package and the Prospectus (and any amendment or supplement thereto) and who will deliver the initial letter referred to in Section 7(f) hereof upon execution and delivery of this Agreement, is and has been, during the periods covered by the financial statements on which it reported contained or incorporated by reference in the Registration Statement, the Pricing Disclosure Package and the Prospectus (and any amendment or supplement thereto), an independent registered public accounting firm with respect to the Partnership and its Subsidiaries, as required by the Securities Act and the Rules and Regulations and the Public Company Accounting Oversight Board (United States) (the “PCAOB”).

(c) All corporate, partnership and limited liability company proceedings and other legal matters incident to the authorization, form and validity of the Debt Documents, the Registration Statement, the Prospectus and any Issuer Free Writing Prospectus, and all other legal matters relating to the Debt Documents and the transactions contemplated hereby and thereby shall be reasonably satisfactory in all material respects to counsel to the Underwriters, and the Partnership Entities shall have furnished to such counsel all documents and information that they may reasonably request to enable them to pass upon such matters.

(1) the representations, warranties and agreements of the Partnership contained in this Agreement in Section 1 are true and correct on and as of the Delivery Date, and the Partnership has complied with all the agreements contained in this Agreement and satisfied all the conditions on their part to be performed or satisfied hereunder at or prior to the Delivery Date;

(2) the Prospectus has been timely filed with the Commission in accordance with Section 5(a)(i) of this Agreement; no stop order suspending the effectiveness of the Registration Statement or any part thereof has been issued; and no proceedings for that purpose have been instituted or, to the knowledge of such officers, threatened by the Commission; all requests of the Commission, if any, for inclusion of additional information in the Registration Statement or the Prospectus or otherwise has been complied with; and the Commission has not notified the Partnership of any objection to the use of the form of the Registration Statement or any post-effective amendment thereto; and

(3) they have carefully examined the Registration Statement, the Prospectus and the Pricing Disclosure Package, and, in their opinion, (A) (i) the Registration Statement, including the documents incorporated by reference therein, as of the most recent Effective Date, (ii) the Prospectus, including the documents incorporated by reference therein, as of its date and on the Delivery Date, and (iii) the Pricing Disclosure Package, as of the Applicable Time, did not and do not contain any untrue statement of a material fact and did not and do not omit to state a material fact required to be stated therein or necessary in order to make the statements therein (in the case of the Prospectus, in the light of the circumstances under which they were made) not misleading, and (B) since the Effective Date, no event has occurred that should have been set forth in a supplement or amendment to the Registration Statement, the Prospectus or any Issuer Free Writing Prospectus that has not been so set forth.

(i) None of the Partnership Entities shall have sustained, since the date of the latest audited financial statements included or incorporated by reference in the Pricing Disclosure Package and the Prospectus (i) any material loss or interference with its business from fire, explosion, flood, accident or other calamity, whether or not covered by insurance, or from any labor dispute or court or governmental action, investigation, order or decree, otherwise than as set forth or contemplated in the Pricing Disclosure Package, or shall have become a party to or the subject of any litigation, court or governmental action, investigation, order or decree that is materially adverse to the Partnership Entities, taken as whole, or (ii) any change or decrease specified in the letters referred to in paragraph (f) or (g) of this Section 7, or any change, or any development involving a prospective material adverse change, in or affecting the general affairs, operations, properties, business, prospects, capitalization, management, condition (financial or otherwise), securityholders’ equity or results of operations or net worth of the Partnership Entities, taken as a whole, other than as set forth or contemplated in the Pricing Disclosure Package, the effect of which, in any such case described in clause (i) or (ii) above, is, in the reasonable judgment of the Representatives, so material and adverse as to make it impracticable or inadvisable to proceed with the public offering or the delivery of the Notes being delivered on the Delivery Date on the terms and in the manner contemplated in the Pricing Disclosure Package.

(j) Subsequent to the execution and delivery of this Agreement, no downgrading shall have occurred in the rating accorded the debt securities or any preferred equity securities of any of the Partnership Entities that are rated by any “nationally recognized statistical rating organization” (as that term is defined by the Commission for purposes of Section 3(a)(62) of the Exchange Act), and no such organization shall have publicly announced that it has under surveillance or review, with possible negative implications, its ratings of any such debt securities or any preferred equity securities.

Section 8. Indemnification and Contribution.

(a) The Partnership shall indemnify and hold harmless each Underwriter, the directors, officers, employees and agents of each Underwriter, affiliates of any Underwriter who have participated in the distribution of the Notes as underwriters, and each person, if any, who controls any Underwriter within the meaning of Section 15 of the Securities Act, from and against any loss, claim, damage or liability, joint or several, or any action in respect thereof (including, but not limited to, any loss, claim, damage, liability or action relating to purchases and sales of Notes), to which that Underwriter, director, officer, employee, agent, affiliate or controlling person may become subject, under the Securities Act or otherwise, insofar as such loss, claim, damage, liability or action arises out of, or is based upon, (i) any untrue statement or alleged untrue statement of a material fact contained in (A) the Preliminary Prospectus, the Registration Statement, the Prospectus or in any amendment or supplement thereto, (B) any Issuer Free Writing Prospectus or in any amendment or supplement thereto, (C) any Permitted Issuer Information used or referred to in any “free writing prospectus” (as defined in Rule 405 of the Rules and Regulations) used or referred to by any Underwriter, or (D) any “road show” (as defined in Rule 433 of the Rules and Regulations) not constituting an Issuer Free Writing Prospectus (a “Non-Prospectus Road Show”) or (E) any Blue Sky Application or other document prepared or executed by the Partnership (or based upon any written information furnished by the Partnership for use therein) specifically for the purpose of qualifying any or all of the Notes under the securities laws of any state or other jurisdiction (any such application, document or information being hereinafter called a “Blue Sky Application”), or (ii) the omission or alleged omission to state in the Preliminary Prospectus, the Registration Statement, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto or in any Permitted Issuer Information, any Non-Prospectus Road Show or

any Blue Sky Application, any material fact required to be stated therein or necessary to make the statements therein (in the case of all of the foregoing, other than the Registration Statement, in the light of the circumstances under which they were made) not misleading, and shall reimburse each Underwriter and each such director, officer, employee, agent, affiliate or controlling person promptly upon demand for any legal or other expenses reasonably incurred by that Underwriter, director, officer, employee, agent, affiliate or controlling person in connection with investigating or defending or preparing to defend against any such loss, claim, damage, liability or action as such expenses are incurred; provided, however, that the Partnership shall not be liable in any such case to the extent that any such loss, claim, damage, liability or action arises out of, or is based upon, any untrue statement or alleged untrue statement or omission or alleged omission made in the Preliminary Prospectus, the Registration Statement, the Prospectus, any Issuer Free Writing Prospectus, or in any such amendment or supplement thereto or in any Permitted Issuer Information, any Non-Prospectus Road Show or any Blue Sky Application, in reliance upon and in conformity with written information concerning any Underwriter furnished to the Partnership through the Representatives by or on behalf of any Underwriter specifically for inclusion therein, which information consists solely of the information specified in Section 8(e) hereof. The foregoing indemnity agreement is in addition to any liability which the Partnership may otherwise have to any Underwriter or to any director, officer, employee, agent, affiliate or controlling person of that Underwriter.

(b) Each Underwriter, severally and not jointly, shall indemnify and hold harmless the Partnership, its employees, the officers and directors of the General Partner, and each person, if any, who controls the Partnership within the meaning of Section 15 of the Securities Act, from and against any loss, claim, damage or liability, joint or several, or any action in respect thereof, to which the Partnership or any such officer, director, employee or controlling person may become subject, under the Securities Act or otherwise, insofar as such loss, claim, damage, liability or action arises out of, or is based upon, (i) any untrue statement or alleged untrue statement of a material fact contained in the Preliminary Prospectus, the Registration Statement, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto or in any Non-Prospectus Road Show or Blue Sky Application, or (ii) the omission or alleged omission to state in the Preliminary Prospectus, the Registration Statement, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto or in any Non-Prospectus Road Show or Blue Sky Application, any material fact required to be stated therein or necessary to make the statements therein (in the case of all of the foregoing, other than the Registration Statement, in light of the circumstances under which they were made) not misleading, but in each case only to the extent that the untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information concerning such Underwriter furnished to the Partnership through the Representatives by or on behalf of that Underwriter specifically for inclusion therein, which information is limited to the information set forth in Section 8(e) hereof. The foregoing indemnity agreement is in addition to any liability that any Underwriter may otherwise have to the Partnership, or any such officer, director, employee or controlling person.

(c) Promptly after receipt by an indemnified party under this Section 8 of notice of any claim or the commencement of any action, the indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under this Section 8, notify the indemnifying party in writing of the claim or the commencement of that action; provided, however, that the failure to notify the indemnifying party shall not relieve it from any liability which it may have under this Section 8 except to the extent it has been materially prejudiced by such failure and, provided, further, that the failure to notify the indemnifying party shall not relieve it from any liability which it may have to an indemnified party otherwise than under this Section 8. If any such claim or action shall be brought against an indemnified party, and it shall notify the indemnifying party thereof, the indemnifying party, upon request of the indemnified party, shall retain counsel reasonably satisfactory to the indemnified party to represent the indemnified party and any others the indemnifying party may designate in such proceeding and shall pay the fees and disbursements of such counsel related to such proceeding. In any such proceeding, any indemnified party shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel or (ii) the named parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood that the indemnifying party shall not, in respect of the legal expenses of any indemnified party in connection with any proceeding or related proceedings in the same jurisdiction, be liable for (i) the fees and expenses of more than one separate firm (in addition to any local counsel) for all Underwriters and all persons, if any, who control any Underwriter within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act or who are affiliates of any Underwriter within the meaning of Rule 405 under the Securities Act, and (ii) the fees and expenses of more than one separate firm (in addition to any local counsel) for the Partnership Entities, the directors and officers of the General Partner who sign the Registration Statement and each person, if any, who controls the Partnership Entities within the meaning of either such Section, and that all such fees and expenses shall be reimbursed as they are incurred. In the case of any such separate firm for the Underwriters and such control persons and affiliates of any Underwriters, such firm shall be designated in writing by the Representatives. In the case of any such separate firm for the Partnership Entities, and such directors, officers and control persons of the General Partner, such firm shall be designated in writing by the Partnership. No indemnifying party shall (A) without the prior written consent of the indemnified parties (which consent shall not be unreasonably withheld), settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding and does not include any findings of fact or admissions of fault or culpability as to the indemnified party, or (B) be liable for any settlement of any such action effected without its written consent (which consent shall not be unreasonably withheld), but if settled with the consent of the indemnifying party or if there be a final judgment for the plaintiff in any such action, the indemnifying party agrees to indemnify and hold harmless any indemnified party from and against any loss or liability by reason of such settlement or judgment.

(d) If the indemnification provided for in this Section 8 shall for any reason be unavailable to or insufficient to hold harmless an indemnified party under Section 8(a) or Section 8(b) in respect of any loss, claim, damage or liability, or any action in respect thereof, referred to therein, then each indemnifying party shall, in lieu of indemnifying such indemnified party, contribute to the amount paid or payable by such indemnified party as a result of such loss, claim,

damage or liability, or action in respect thereof, (i) in such proportion as shall be appropriate to reflect the relative benefits received by the Partnership, on the one hand, and the Underwriters on the other, from the offering of the Notes or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Partnership, on the one hand, and the Underwriters on the other, with respect to the statements or omissions that resulted in such loss, claim, damage or liability, or action in respect thereof, as well as any other relevant equitable considerations. The relative benefits received by the Partnership, on the one hand, and the Underwriters on the other, with respect to such offering shall be deemed to be in the same proportion as the total net proceeds from the offering of the Notes purchased under this Agreement (before deducting expenses) received by the Partnership, as set forth in the table on the cover page of the Prospectus, on the one hand, and the total underwriting discounts and commissions received by the Underwriters with respect to the Notes purchased under this Agreement, as set forth in the table on the cover page of the Prospectus, on the other hand. The relative fault shall be determined by reference to whether the untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Partnership or the Underwriters, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such statement or omission. The Partnership and the Underwriters agree that it would not be just and equitable if contributions pursuant to this Section 8(d) were to be determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take into account the equitable considerations referred to herein. The amount paid or payable by an indemnified party as a result of the loss, claim, damage or liability, or action in respect thereof, referred to above in this Section 8(d) shall be deemed to include, for purposes of this Section 8(d), any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 8(d), no Underwriter shall be required to contribute any amount in excess of the amount by which the net proceeds from the sale of the Notes underwritten by it exceeds the amount of any damages that such Underwriter has otherwise paid or become liable to pay by reason of any untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ respective obligations to contribute as provided in this Section 8(d) are several in proportion to their respective underwriting obligations and not joint.

(e) The Underwriters severally confirm and the Partnership acknowledges and agrees that the statements regarding delivery of the Securities by the Underwriters set forth on the cover page of, and (i) the concession and reallowance figures, (ii) the second sentence and fourth sentence of the third paragraph relating to market making by the Underwriters and (iii) the eighth and ninth paragraphs relating to stabilization by the Underwriters appearing under the caption “Underwriting” in, the Preliminary Prospectus and the Prospectus are correct and constitute the only information concerning such Underwriters furnished in writing to the Partnership by or on behalf of the Underwriters specifically for inclusion in the Preliminary Prospectus, the Registration Statement, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto or in any Non-Prospectus Road Show.

Section 9. Defaulting Underwriters.

(a) If, on the Delivery Date, any Underwriter defaults in its obligations to purchase the principal amount of Notes which it has agreed to purchase under this Agreement, the remaining non-defaulting Underwriters may in their discretion arrange for the purchase of such principal amount of Notes by the non-defaulting Underwriters or other persons satisfactory to the Partnership on the terms contained in this Agreement. If, within 36 hours after any such default by any Underwriter, the non-defaulting Underwriters do not arrange for the purchase of such principal amount of Notes, then the Partnership shall be entitled to a further period of 36 hours within which to procure other persons satisfactory to the non-defaulting Underwriters to purchase such principal amount of Notes on such terms. In the event that within the respective prescribed periods, the non-defaulting Underwriters notify the Partnership that they have so arranged for the purchase of such principal amount of Notes, or the Partnership notify the non-defaulting Underwriters that they have so arranged for the purchase of such principal amount of Notes, either the non-defaulting Underwriters or the Partnership may postpone the Delivery Date for up to seven full business days in order to effect any changes that in the opinion of counsel for the Partnership or counsel for the Underwriters may be necessary in the Registration Statement, the Prospectus or in any other document or arrangement, and the Partnership agrees to promptly prepare any amendment or supplement to the Registration Statement, the Prospectus or in any such other document or arrangement that effects any such changes. As used in this Agreement, the term “Underwriter” includes, for all purposes of this Agreement unless the context requires otherwise, any party not listed in Schedule 1 hereto that, pursuant to this Section 9, purchases Notes that a defaulting Underwriter agreed but failed to purchase.

(b) If, after giving effect to any arrangements for the purchase of the principal amount of Notes of a defaulting Underwriter or Underwriters by the non-defaulting Underwriters and the Partnership as provided in Section 9(a), the total principal amount of Notes that remains unpurchased does not exceed one-eleventh of the total aggregate principal amount of all of the Notes, then the Partnership shall have the right to require each non-defaulting Underwriter to purchase the principal amount of Notes that such Underwriter agreed to purchase hereunder plus such Underwriter’s pro rata share (based on the total principal amount of Notes that such Underwriter agreed to purchase hereunder) of the principal amount of Notes of such defaulting Underwriter or Underwriters for which such arrangements have not been made; provided that the non-defaulting Underwriters shall not be obligated to purchase more than 110% of the total principal amount of Notes that it agreed to purchase on the Delivery Date pursuant to the terms of Section 2.

(c) If, after giving effect to any arrangements for the purchase of the principal amount of Notes of a defaulting Underwriter or Underwriters by the non-defaulting Underwriters and the Partnership as provided in Section 9(a), the total principal amount of Notes that remains unpurchased exceeds one-eleventh of the total aggregate principal amount of all of the Notes, or if the Partnership shall not exercise the right described in Section 9(b), then this Agreement shall terminate without liability on the part of the non-defaulting Underwriters except that the provisions of Section 8 shall not terminate and shall remain in effect. Any termination of this Agreement pursuant to this Section 9 shall be without liability on the part of the Partnership, except that the Partnership will continue to be liable for the payment of expenses as set forth in Sections 6 and 11 and except that the provisions of Section 8 shall not terminate and shall remain in effect.

(d) Nothing contained herein shall relieve a defaulting Underwriter of any liability it may have to the Partnership or any non-defaulting Underwriter for damages caused by its default.

Section 10. Termination.

The obligations of the Underwriters hereunder may be terminated by the Representatives by notice given to and received by the Partnership prior to delivery of and payment for the Notes if, at any time prior to such delivery and payment, (i) trading in any securities of the Partnership shall have been suspended on any exchange or in the over-the-counter market by the Commission or the NYSE, (ii) trading in securities generally on the NYSE, NYSE Alternext US, the NASDAQ Stock Market, or in the over-the-counter market shall have been suspended or limited or minimum prices shall have been established on any such exchange or market by the Commission, by such exchange, or by any other regulatory body or governmental authority, (iii) a banking moratorium shall have been declared either by Federal or New York State authorities, or (iv) there shall have occurred any outbreak or escalation of hostilities, declaration by the United States of a national emergency or war, or other calamity or crisis, the effect of which on financial markets in the United States is such as to make it, in the sole judgment of the Representatives, impractical or inadvisable to proceed with the offering, sale or delivery of the Notes as contemplated in the Preliminary Prospectus or the Prospectus (exclusive of any amendment or supplement thereto).

Section 11. Reimbursement of Underwriters’ Expenses.

If the Partnership shall fail to tender the Notes for delivery to the Underwriters by reason of any failure, refusal or inability on the part of the Partnership to perform any agreement on its part to be performed, or because any other condition to the Underwriters’ obligations hereunder required to be fulfilled by the Partnership is not fulfilled for any reason, the Partnership will reimburse the Underwriters for all reasonable out-of-pocket expenses (including fees and disbursements of counsel) incurred by the Underwriters in connection with this Agreement and the proposed purchase of the Notes, and upon demand the Partnership shall pay the full amount thereof to the Representatives. If this Agreement is terminated (i) pursuant to Section 10(ii), (iii) or (iv), or (ii) pursuant to Section 9 by reason of the default of one or more Underwriters, the Partnership shall not be obligated to reimburse any Underwriter, in the case of clause (i) of this sentence, or any defaulting Underwriter, in the case of clause (ii) of this sentence, on account of the expenses described in the first sentence of this Section 11.

Section 12. Research Independence.

The Partnership acknowledges that the Underwriters’ research analysts and research departments are required to be independent from their respective investment banking divisions and are subject to certain regulations and internal policies, and that such Underwriters’ research analysts may hold views and make statements or investment recommendations and/or publish research reports with respect to the Partnership, and/or the offering that differ from the views of their respective investment banking divisions. The Partnership hereby waives and releases, to the fullest extent permitted by law, any claims that the Partnership may have against the Underwriters with respect to any conflict of interest that may arise from the fact that the views expressed by their independent research analysts and research departments may be different from or inconsistent with the views or advice communicated to the Partnership by such Underwriters’ investment

banking divisions.

Issuer:	Energy Transfer LP

Expected Ratings (Moody’s / S&P / Fitch)*:	[Intentionally Omitted]

Security Type:	Senior Unsecured Notes

Form:	SEC Registered

Pricing Date:	February 18, 2025

Settlement Date (T+10):	March 4, 2025. We expect that delivery of the notes will be made against payment therefor on or about March 4, 2025, which will be the tenth business day following the date hereof. This settlement cycle is referred to as “T+10.” Under Rule 15c6-1 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), trades in the secondary market generally are required to settle in one business day, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade notes prior to the date that is one business day preceding the settlement date, will be required, by virtue of the fact that the notes initially will settle T+10, to specify an alternate settlement cycle at the time of any such trade to prevent a failed settlement. Purchasers of notes who wish to trade notes prior to the date that is one business day preceding the settlement date should consult their own advisors.

Ranking:	The notes will be our general unsecured obligations. The notes will rank equally in right of payment with all our existing and future senior debt, including debt under our revolving credit facility and our existing senior notes, senior in right of payment to our existing and future subordinated debt and junior to the indebtedness and other obligations, including trade payables, of our subsidiaries that do not guarantee the notes. As of December 31, 2024, after giving effect to this offering and the application of the net proceeds as set forth under “Use of Proceeds” in the Notes Preliminary Prospectus Supplement (as defined below), we would have had total senior debt of $58.4 billion, total junior subordinated debt of $1.8 billion, and we would have been able to incur an additional $5.0 billion of debt under our revolving credit facility.

Net Proceeds (before offering expenses):	$2,968,802,000
