MERGER PROPOSAL—YOUR VOTE IS VERY IMPORTANT

September 11, 2018

Dear Common Unitholders of Energy Transfer Partners, L.P.:

On August 1, 2018, Energy Transfer Equity, L.P. (“ETE”), Energy Transfer Partners, L.P. (“ETP”) and certain of their affiliates entered into a merger agreement (as may be amended from time to time, the “merger agreement”), pursuant to which Streamline Merger Sub, LLC, a wholly owned subsidiary of ETE, will merge with and into ETP, with ETP continuing as the surviving entity and a subsidiary of ETE (the “merger”). The board of directors (the “ETP Board”) of Energy Transfer Partners, L.L.C. (“ETP Managing GP”), the general partner of Energy Transfer Partners GP, L.P., the general partner of ETP, approved and agreed to submit the merger agreement and the merger to a vote of ETP common unitholders following the recommendation of the conflicts committee of the ETP Board (the “ETP Conflicts Committee”). The ETP Conflicts Committee has determined that the merger agreement and the merger are advisable and fair and reasonable to ETP, and in the best interests of ETP and the unaffiliated ETP common unitholders and the ETP Board has determined that the form, terms and provisions of the merger agreement and the transactions contemplated thereby, including the merger and the ETP LPA amendment (as defined below), are advisable, fair and reasonable to and in the best interests of ETP and its common unitholders, and in each case, has approved the merger agreement and the merger. Under the terms of the merger agreement, subject to certain adjustments, holders of common units representing limited partner interests in ETP (“ETP common units”) will receive, for each ETP common unit held, 1.28 common units representing limited partner interests in ETE (“ETE common units”).

The merger consideration to be received by holders of ETP common units is valued at $23.59 per unit based on the closing price of ETE common units as of August 1, 2018, the last trading day before the public announcement of the merger, representing an approximate 11% premium to the closing price of ETP common units of $21.21 on August 1, 2018, a 15% premium to the volume-weighted average closing price of ETP common units for the ten trading days ended August 1, 2018 and a 19% premium to the volume-weighted average closing price of ETP common units for the 30 trading days ended August 1, 2018. The merger consideration is valued at $22.41 per unit based on the closing price of ETE common units as of September 6, 2018, the most recent trading day prior to the date of this proxy statement/prospectus, representing a 0.1% discount to the closing price of ETP common units of $22.44 on September 6, 2018, and a 0.5% discount to the volume-weighted average closing price of ETP common units for the five trading days ended September 6, 2018.

Immediately following the completion of the merger, it is expected that ETP common unitholders will own approximately 56% of the outstanding ETE common units, based on the number of ETE common units outstanding, on a fully diluted basis, as of September 6, 2018. The common units of ETE and ETP are traded on the New York Stock Exchange (“NYSE”) under the symbols “ETE” and “ETP,” respectively. Following the consummation of the merger, it is expected that ETE will change its name to “Energy Transfer LP” and apply to continue the listing of its common units on the NYSE under the new symbol “ET.” It is also expected that ETP will change its name to “Energy Transfer Operating, L.P.” and that the Series C Fixed-to-Floating Rate Cumulative Redeemable Perpetual Preferred Units representing limited partner interests in ETP and the Series D Fixed-to-Floating Rate Cumulative Redeemable Perpetual Preferred Units representing limited partner interests in ETP will continue to trade on the NYSE under the symbols “ETPprC” and “ETPprD,” respectively.

ETP is holding a special meeting of its common unitholders at the Hilton Dallas Park Cities Hotel, 5954 Luther Lane, Dallas, Texas 75225, on October 18, 2018 at 10:00 a.m., local time, to obtain the vote of its common unitholders to adopt the merger agreement and the transactions contemplated thereby. Your vote is very important regardless of the number of ETP common units you own. The merger cannot be completed unless the holders of at least a majority of the outstanding ETP common

units, other than the ETP common units owned by ETE and its affiliates, and the holders of at least a majority of the outstanding ETP common units vote for the adoption of the merger agreement and the transactions contemplated thereby at the special meeting. The ETP Board recommends that ETP common unitholders vote “FOR” the adoption of the merger agreement and the transactions contemplated thereby and “FOR” the proposal to approve the adjournment of the special meeting, if necessary, to solicit additional proxies if there are not sufficient votes to adopt the merger agreement at the time of the special meeting. Pursuant to the merger agreement, ETE, which directly or indirectly owns all of the incentive distribution rights and the general partner interest in ETP, as well as approximately 2.4% of the ETP common units outstanding as of September 10, 2018, has agreed to vote all of the ETP common units owned beneficially or of record by ETE or its subsidiaries in favor of the approval of the merger agreement and the merger and the approval of any actions required in furtherance thereof. Whether or not you expect to attend the special meeting in person, we urge you to submit your proxy as promptly as possible through one of the delivery methods described in the accompanying proxy statement/prospectus.

In addition, we urge you to read carefully the accompanying proxy statement/prospectus (and the documents incorporated by reference into the accompanying proxy statement/prospectus), which includes important information about the merger agreement, the proposed merger and the special meeting.  Please pay particular attention to the section titled “Risk Factors” beginning on page 30 of the accompanying proxy statement/prospectus.

On behalf of the ETP Board, we thank you for your continued support.

Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of the securities to be issued under the accompanying proxy statement/prospectus or determined that the accompanying proxy statement/prospectus is accurate or complete. Any representation to the contrary is a criminal offense.

The accompanying proxy statement/prospectus is dated September 11, 2018 and is first being mailed to the common unitholders of ETP on or about September 11, 2018.

Sincerely,

Kelcy L. Warren

NOTICE OF SPECIAL MEETING OF COMMON UNITHOLDERS

TO BE HELD ON OCTOBER 18, 2018

To the Common Unitholders of Energy Transfer Partners, L.P.:

Notice is hereby given that a special meeting of common unitholders of Energy Transfer Partners, L.P. (“ETP”), will be held at the Hilton Dallas Park Cities Hotel, 5954 Luther Lane, Dallas, Texas 75225, on October 18, 2018 at 10:00 a.m., local time, solely for the following purposes:

These items of business, including the merger agreement and the merger, are described in detail in the accompanying proxy statement/prospectus. The board of directors of ETP Managing GP (the “ETP Board”) has determined that the form, terms and provisions of the merger agreement and the transactions contemplated thereby, including the merger and the ETP LPA amendment (as defined below), are advisable, fair and reasonable to and in the best interests of ETP and its common unitholders and the conflicts committee of the ETP Board (the “ETP Conflicts Committee”) has determined that the merger agreement and the merger are advisable and fair and reasonable to ETP, and in the best interests of ETP and the unaffiliated ETP common unitholders, and in each case, has approved the merger agreement and the merger. Therefore, the ETP Board, based on the recommendation of the ETP Conflicts Committee, recommends that ETP common unitholders vote “FOR” the adoption of the merger agreement and the transactions contemplated thereby and “FOR” the proposal to approve the adjournment of the special meeting, if necessary, to solicit additional proxies in favor of such adoption.

Only common unitholders of record as of the close of business on September 10, 2018 are entitled to notice of the special meeting and to vote at the special meeting or at any adjournment or postponement thereof. A list of common unitholders entitled to vote at the special meeting will be available in our offices located at 8111 Westchester Drive, Suite 600, Dallas, Texas 75225 during regular business hours for a period of 10 days before the special meeting, and at the place of the special meeting during the special meeting. Pursuant to the merger agreement, ETE has agreed to vote all of the common units representing limited partner interests in ETP (“ETP common units”) owned beneficially or of record by ETE or its subsidiaries in favor of the adoption of the merger agreement and the merger and the approval of any actions required in furtherance thereof, which includes, if necessary, the adjournment proposal. As of September 10, 2018, ETE and its subsidiaries collectively held 27,535,127 ETP common units, representing approximately 2.4% of the ETP common units entitled to vote at the special meeting.

Adoption of the merger agreement and the transactions contemplated thereby by the ETP common unitholders is a condition to the consummation of the merger and requires the affirmative vote of holders of at least a majority of the outstanding ETP common units, other than ETP common units held by ETE and its affiliates, and the affirmative vote of holders of at least a majority of the outstanding ETP common units. Therefore, your vote is very important. Your failure to vote your ETP common units will have the same effect as a vote “AGAINST” the adoption of the merger agreement and the transactions contemplated thereby.

By order of the board of directors,

James M. Wright, Jr.

General Counsel

Dallas, Texas

QUESTIONS AND ANSWERS

Set forth below are questions that you, as a common unitholder of ETP, may have regarding the merger proposal, the adjournment proposal and the special meeting, and brief answers to those questions. You are urged to read carefully this proxy statement/prospectus and the other documents referred to in this proxy statement/prospectus in their entirety, including the merger agreement, which is attached as Annex A to this proxy statement/prospectus, and the documents incorporated by reference into this proxy statement/prospectus, because this section may not provide all of the information that is important to you with respect to the merger and the special meeting. You may obtain a list of the documents incorporated by reference into this proxy statement/prospectus in the section titled “Where You Can Find More Information.”

Q: Why am I receiving this proxy statement/prospectus?

A: ETE, ETP and certain of their affiliates have agreed to a merger, pursuant to which ETE Merger Sub, a wholly owned subsidiary of ETE, will merge with and into ETP. ETP will continue its existence as the surviving entity and a subsidiary of ETE, but the ETP common units will no longer be publicly traded. In order to complete the merger, ETP common unitholders must vote to adopt the merger agreement and the transactions contemplated thereby. ETP is holding a special meeting of its common unitholders to obtain such unitholder approval.

In connection with the merger, ETE will issue ETE common units as the consideration to be paid to holders of ETP common units. This document is being delivered to you as both a proxy statement of ETP and a prospectus of ETE in connection with the merger. It is the proxy statement by which the ETP Board is soliciting proxies from you to vote on the adoption of the merger agreement and the transactions contemplated thereby, including the merger, at the ETP special meeting or at any adjournment or postponement thereof. It is also the prospectus by which ETE will issue ETE common units to you in connection with the merger.

Q: What will happen in the merger?

A: Pursuant to the merger agreement, at the effective time of the merger (the “effective time”), ETE Merger Sub will merge with and into ETP. ETP will be the surviving limited partnership in the merger and will be a subsidiary of ETE, but the ETP common units will no longer be publicly traded. Following the consummation of the merger, it is expected that ETE will change its name to “Energy Transfer LP” and apply to continue the listing of its common units on the NYSE under the new symbol “ET.” At the closing of the merger, ETP will change its name to “Energy Transfer Operating, L.P.”

Q: What will I receive in the merger?

A: If the merger is completed, each ETP common unit issued and outstanding as of immediately prior to the effective time (other than ETP common units held by ETE or its subsidiaries) will be converted automatically into the right to receive 1.28 (the “exchange ratio”) ETE common units (the “merger consideration”). ETP common unitholders will not receive any fractional ETE common units in the merger. Instead, with respect to each holder of ETP common units whose ETP common units are converted pursuant to the merger agreement who otherwise would have received a fraction of an ETE common unit will be entitled to receive a whole ETE common unit. Based on the closing price of ETE common units on the New York Stock Exchange (the “NYSE”) on August 1, 2018, the last trading day prior to the public announcement of the merger, the merger consideration represented approximately $23.59 in value for each ETP common unit. Based on the closing price of $17.51 for ETE common units on the NYSE on September 6, 2018, the most recent practicable trading day prior to the date of this proxy statement/prospectus, the merger consideration represented approximately $22.41 in value for each ETP common unit. The market price of ETE common units will fluctuate prior to the merger, and the market price of ETE common units when received by ETP common unitholders after the merger is completed could be greater or less than the current market price of ETE common units. See “Risk Factors.”

Q: What will happen to my ETP restricted units and restricted phantom units in the merger?

A: If the merger is completed, each unvested award of restricted units and restricted phantom units outstanding under any ETP equity plan (“ETP restricted units” or “ETP restricted phantom units,” as applicable) will, as of the effective time, be converted into the right to receive a comparable restricted equity award with respect to ETE common units on the same terms and conditions as were applicable to the corresponding award of ETP (including the right to receive distribution equivalents with respect to such award), except that the number of ETE common units covered by such comparable award will be equal to the number of ETP common units covered by the corresponding award of ETP multiplied by the exchange ratio, rounded up to the nearest whole unit.

Q: What will happen to the other series and classes of ETP units in the merger?

A: The merger agreement provides that (i) at the effective time, the Class E Units representing limited partner interests in ETP (the “Class E Units”), Class G Units representing limited partner interests in ETP (the “Class G Units”), Class K units representing limited partner interests in ETP (the “Class K Units”), Series A Fixed-to-Floating Rate Cumulative Redeemable Perpetual Preferred Units representing limited partner interests in ETP (the “Series A Preferred Units”), Series B Fixed-to-Floating Rate Cumulative Redeemable Perpetual Preferred Units representing limited partner interests in ETP (the “Series B Preferred Units”), Series C Fixed-to-Floating Rate Cumulative Redeemable Perpetual Preferred Units representing limited partner interests in ETP (the “Series C Preferred Units”) and Series D Fixed-to-Floating Rate Cumulative Redeemable Perpetual Preferred Units representing limited partner interests in ETP (the “Series D Preferred Units” and, together with the Series A Preferred Units, the Series B Preferred Units and the Series C Preferred Units, the “Preferred Units”), all of which have been issued and are outstanding immediately prior to the effective time, will be unchanged and remain outstanding, (ii) immediately prior to the effective time, the outstanding Class I Units representing limited partner interests in ETP (the “Class I Units”) and Class J Units representing limited partner interests in ETP (the “Class J Units”), all of which have been issued and are outstanding immediately prior to the effective time, will be cancelled, and (iii) immediately prior to the effective time, all of the incentive distribution rights in ETP issued and outstanding immediately prior to the effective time will be converted into 1,168,205,710 ETP common units. The Series C Preferred Units and the Series D Preferred Units will continue to be listed on the NYSE following the completion of the merger. The general partner interest in ETP will be converted into a non-economic general partner interest in exchange for the issuance of 18,448,341 ETP common units.

Q: What will the ownership of ETE GP and its affiliates be in ETE following the completion of the merger?

A: As a condition to the completion of the merger, ETE has agreed to issue to ETE GP a new class of limited partner interests, the Class A units (the “ETE Class A Units”). The number of ETE Class A Units to be issued to ETE GP will allow ETE GP and its affiliates to retain their current voting interest in ETE following the completion of the merger. Currently, ETE GP and its affiliates have an approximate 31% voting interest in ETE and, if the ETE Class A Units were not issued to ETE GP, ETE GP and its affiliates would have an approximate 13.5% voting interest in ETE, based on the 1,166,403,685 ETP common units and 1,158,206,626 ETE common units outstanding as of August 1, 2018 and the number of ETE common units owned by ETE GP and its affiliates as of August 1, 2018. As a result of the issuance of the ETE Class A Units, following the completion of the merger, the voting interest in ETE represented by the ETE common units held by ETE GP and its affiliates and the voting interest in ETE represented by the ETE Class A Units held by ETE GP would give ETE GP and its affiliates an aggregate voting interest of approximately 31%. Please read “The Merger—Effect of the Merger” beginning on page 48 of this proxy statement/prospectus.

Q: What are the ETE Class A Units and how will they impact holders of ETE common units following the merger?

A: Pursuant to the ETE partnership agreement, ETE GP has a preemptive right to acquire, in connection with any issuance of common units by ETE (including the issuance of ETE common units pursuant to the

2

merger), additional ETE common units in order to allow ETE GP to maintain the percentage interest of ETE GP and its affiliates of ETE’s outstanding common units prior to any such issuance. As of August 1, 2018, ETE GP and its affiliates owned approximately 31% of ETE’s outstanding common units. Absent the exercise of this preemptive right, the percentage ownership of ETE GP and its affiliates would be diluted to approximately 13.5% as a result of the issuance of the merger consideration to the former ETP common unitholders in connection with the closing of the merger. ETE GP has agreed to waive its preemptive right in connection with the issuance of ETE common units pursuant to the merger, and ETE has agreed to issue to ETE GP a newly created class of limited partner interests in ETE, the ETE Class A Units, that will be entitled to vote together with the ETE common units, as a single class, on any matter for which the holders of ETE common units are entitled to vote, except as required by law. The number of ETE Class A Units issued to ETE GP will be calculated to ensure that the ETE common units and the ETE Class A Units held by ETE GP and its affiliates immediately following the merger represent the same relative voting power as the ETE common units held by ETE GP and its affiliates represented prior to the merger. Following the completion of the merger, for so long as Kelcy Warren is an officer or a director of ETE GP, upon the issuance by ETE of additional ETE common units or any securities that have voting rights that are pari passu with the ETE common units, ETE will issue to the holder of ETE Class A Units a number of additional ETE Class A Units such that the holder maintains a voting interest in ETE that is identical to its voting interest in ETE prior to such issuance.

The ETE Class A Units will not be entitled to distributions and otherwise have no economic attributes, except that the ETE Class A Units in the aggregate will be entitled to an aggregate $100 distribution prior and in preference to any distribution of assets to the holders of any other classes or series of securities of ETE upon any liquidation, dissolution or winding up of ETE. The ETE Class A Units are not convertible into, or exchangeable for, ETE common units. In addition to the other voting rights of the ETE Class A Units, without the approval of 66 2/3% of the ETE Class A Units, ETE may not take any action that disproportionately or materially adversely affects the rights, preferences or privileges of the ETE Class A Units or amend the terms of the ETE Class A Units. Without the prior approval of a conflicts committee of the board of directors of ETE GP (the “ETE Board”), the ETE Class A Units may not be transferred to any person or entity, other than to Kelcy Warren, Ray Davis or to any trust, family partnership or family limited liability company the sole beneficiaries, partners or members of which are Kelcy Warren, Ray Davis or their respective relatives. Please read “The Merger—Effect of the Merger” beginning on page 48 of this proxy statement/prospectus and “Risk Factors—ETE common unitholders have limited voting rights and are not entitled to elect ETE’s general partner or the directors of ETE’s general partner” beginning on page 33 of this proxy statement/prospectus.

Q: What happens if the merger is not completed?

A: If the merger agreement and the transactions contemplated thereby are not adopted by ETP common unitholders holding at least a majority of the outstanding ETP common units, other than ETP common units held by ETE and its affiliates (collectively, the “unaffiliated ETP common unitholders”), and by the ETP common unitholders holding at least a majority of the outstanding ETP common units, or if the merger is not completed for any other reason, you will not receive any form of consideration for your ETP common units in connection with the merger. Instead, ETP will remain an independent publicly traded limited partnership and the ETP common units will continue to be listed and traded on the NYSE. If the merger agreement is terminated under specified circumstances, including if ETP common unitholder approval is not obtained, ETP will be required to pay all of the reasonably documented out-of-pocket expenses incurred by ETE and its affiliates in connection with the merger agreement and the transactions contemplated thereby, up to a maximum amount of $30.0 million. In addition, if the merger agreement is terminated under specified circumstances, including due to an adverse recommendation change having occurred, ETP will be required to pay ETE a termination fee of $750.0 million, less any expenses previously paid by ETP to ETE. Following payment of the termination fee, ETP will not be obligated to pay any additional expenses incurred by ETE or its affiliates in connection with the merger. Please read “Proposal 1: The Merger Agreement—Expenses” and “—Termination Fee” beginning on page 100 of this proxy statement/prospectus.

Q: Will I continue to receive future distributions on my ETP common units?

A: Before completion of the merger, ETP expects to continue to pay its regular quarterly cash distribution on the ETP common units, which was $0.565 per ETP common unit for the quarter ended June 30, 2018. However, ETE and ETP will coordinate the timing of distribution declarations leading up to completion of the merger so that, in any quarter, a holder of ETP common units will either receive distributions in respect of its ETP common units or distributions in respect of the ETE common units that such holder will receive in connection with the merger as part of the merger consideration (but will not receive distributions from both ETP and ETE in any single quarter). Receipt of the regular quarterly distribution will not reduce the merger consideration you receive. Upon completion of the merger, you will be entitled only to distributions on any ETE common units you receive as merger consideration and hold through the applicable distribution record date. While ETE provides no assurances as to the level or payment of any future distributions on the ETE common units, and ETE reserves to itself the sole right to determine the amount of its distributions each quarter, with respect to the quarter ended June 30, 2018, ETE paid a cash distribution of $0.305 per ETE common unit on August 20, 2018 to holders of record as of the close of business on August 6, 2018.

The current annualized distribution rate for each ETP common unit is $2.26 (based on the quarterly distribution rate of $0.565 for each ETP common unit that was paid with respect to the quarter ended June 30, 2018). Based on the exchange ratio, the annualized distribution rate for each ETP common unit exchanged for 1.28 ETE common units would be approximately $1.5616 (based on the quarterly distribution rate of $0.305 per ETE common unit paid with respect to the quarter ended June 30, 2018). Accordingly, based on the distribution rates for the quarter ended June 30, 2018, and the exchange ratio, an ETP common unitholder would initially receive approximately 31% less in quarterly cash distributions on an annualized basis after giving effect to the merger. For additional information, please read “Comparative Unit Prices and Distributions.”

Q: What am I being asked to vote on?

A: ETP’s common unitholders are being asked to vote on the following proposals:

The approval of the merger proposal by ETP common unitholders holding at least a majority of the outstanding ETP common units and at least a majority of the outstanding ETP common units held by unaffiliated ETP common unitholders are conditions to the obligations of ETE and ETP to complete the merger. The adjournment proposal is not a condition to the obligations of ETE or ETP to complete the merger.

Q: Does the ETP Board recommend that ETP common unitholders adopt the merger agreement and the transactions contemplated thereby?

A: Yes. The ETP Board has determined that the form, terms and provisions of the merger agreement and the transactions contemplated thereby, including the merger and the ETP LPA amendment (as defined below), are advisable, fair and reasonable to and in the best interests of ETP and its common unitholders and the ETP Conflicts Committee has determined that the merger agreement and the merger are advisable and fair and reasonable to ETP, and in the best interests of ETP and the unaffiliated ETP common unitholders, and in each case, has approved the merger agreement and the merger. Therefore, the ETP Board, based on the recommendation of the ETP Conflicts Committee, recommends that you vote “FOR” the adoption of the merger agreement and the transactions contemplated thereby and “FOR” the proposal to approve the adjournment of the special meeting, if necessary, to solicit additional proxies if there are not sufficient votes to adopt the merger agreement at the time of the special meeting. See “The Merger—Recommendation

4

of the ETP Board; Reasons for the Merger” beginning on page 61 of this proxy statement/prospectus. In considering the recommendation of the ETP Board with respect to the merger agreement and the transactions contemplated thereby, including the merger, you should be aware that directors and executive officers of ETP are parties to agreements or participants in other arrangements that give them interests in the merger that may be different from, or in addition to, your interests as a unitholder of ETP. You should consider these interests in voting on the merger proposal. These different interests are described under “The Merger—Interests of Directors and Executive Officers of ETP in the Merger” beginning on page 83 of this proxy statement/prospectus.

Q: What unitholder vote is required for the approval of each proposal?

A: The following are the vote requirements for the ETP proposals:

Pursuant to the merger agreement, ETE, which directly or indirectly owns all of the incentive distribution rights and the general partner interest in ETP, has agreed to vote all of the ETP common units owned beneficially or of record by ETE or its subsidiaries in favor of the approval of the merger agreement and the transactions contemplated thereby, including the merger, and the approval of any actions required in furtherance thereof, which includes, if necessary, the adjournment proposal. As of September 10, 2018, ETE and its subsidiaries collectively held 27,535,127 ETP common units, representing approximately 2.4% of the ETP common units entitled to vote at the special meeting.

Q: What constitutes a quorum for the special meeting?

A: The holders of at least a majority of the outstanding ETP common units must be represented in person or by proxy at the special meeting in order to constitute a quorum.

Q: When is this proxy statement/prospectus being mailed?

A: This proxy statement/prospectus and the proxy card are first being sent to ETP common unitholders on or about September 11, 2018.

Q: Who is entitled to vote at the special meeting?

A: Holders of ETP common units outstanding as of the close of business on September 10, 2018 (the “record date”) are entitled to one vote per unit at the special meeting.

As of the record date, there were 1,167,186,967 ETP common units outstanding, all of which are entitled to vote at the special meeting.

Q: When and where is the special meeting?

A: The special meeting will be held at the Hilton Dallas Park Cities Hotel, 5954 Luther Lane, Dallas, Texas 75225, on October 18, 2018, at 10:00 a.m., local time.

Q: How do I vote my ETP common units at the special meeting?

A: There are four ways you may cast your vote. You may vote:

Even if you plan to attend the special meeting in person, you are encouraged to submit your proxy as described above so that your vote will be counted if you later decide not to attend the special meeting.

If your ETP common units are held by a bank, broker or other nominee, also known as holding units in “street name,” you should receive instructions from the bank, broker or other nominee that you must follow in order to have your ETP common units voted. Please review such instructions to determine whether you will be able to submit your proxy via Internet or by telephone. The deadline for submitting your proxy by telephone or electronically through the Internet is 11:59 p.m., Eastern Time, on October 17, 2018 (the “telephone/internet deadline”). However, if the special meeting is adjourned to solicit additional proxies, the deadline may be extended.

Q: If my ETP common units are held in “street name” by my broker, will my broker automatically vote my ETP common units for me?

A: No. If your ETP common units are held in an account at a broker or through another nominee, you must instruct the broker or other nominee on how to vote your ETP common units by following the instructions that the broker or other nominee provides to you with these materials. Most brokers offer the ability for unitholders to submit voting instructions by mail by completing a voting instruction card, by telephone and via the Internet.

If you do not provide voting instructions to your broker, your ETP common units will not be voted on any proposal on which your broker does not have discretionary authority to vote. This is referred to in this proxy statement/prospectus and in general as a broker non-vote. In these cases, the broker can register your ETP common units as being present at the special meeting for purposes of determining a quorum, but will not be able to vote on those matters for which specific authorization is required. Under the current rules of the NYSE, brokers do not have discretionary authority to vote on any of the proposals, at the special meeting, including the merger proposal. A broker non-vote will have the same effect as a vote “AGAINST” the merger proposal and the adjournment proposal.

6

Q: How will my ETP common units be represented at the special meeting?

A: If you submit your proxy by telephone, the Internet website or by signing and returning your proxy card, the officers named in your proxy card will vote your ETP common units in the manner you requested if you correctly submitted your proxy. If you sign your proxy card and return it without indicating how you would like to vote your ETP common units, your proxy will be voted as the ETP Board recommends, which is:

Q: Who may attend the special meeting?

A: ETP common unitholders (or their authorized representatives) and ETP’s invited guests may attend the special meeting. All attendees at the special meeting should be prepared to present government-issued photo identification (such as a driver’s license or passport) for admittance.

Q: Is my vote important?

A: Yes, your vote is very important. If you do not submit a proxy or vote in person at the special meeting, it will be more difficult for ETP to obtain the necessary quorum to hold the special meeting. In addition, an abstention or your failure to submit a proxy or to vote in person will have the same effect as a vote “AGAINST” the adoption of the merger agreement and the transactions contemplated thereby, including the merger. If you hold your ETP common units through a bank, broker or other nominee, your bank, broker or other nominee will not be able to cast a vote on such adoption without instructions from you. The ETP Board, based on the recommendation of the ETP Conflicts Committee, recommends that ETP common unitholders vote “FOR” the merger proposal.

Q: Can I revoke my proxy or change my voting instructions?

A: Yes. If you are an ETP common unitholder of record, you may revoke or change your proxy at any time before the telephone/internet deadline or before the polls close at the special meeting by:

If you hold your ETP common units through a bank, broker or other nominee, you must follow the directions you receive from your bank, broker or other nominee in order to revoke your proxy or change your voting instructions.

Q: What happens if I sell my ETP common units after the record date but before the special meeting?

A: The record date for the special meeting is earlier than the date of the special meeting and earlier than the date that the merger is expected to be completed. If you sell or otherwise transfer your ETP common units after the record date but before the date of the special meeting, you will retain your right to vote at the special meeting. However, you will not have the right to receive the merger consideration to be received by ETP’s common unitholders in the merger. In order to receive the merger consideration, you must hold your ETP common units through completion of the merger.

7

Q: What does it mean if I receive more than one proxy card or vote instruction card?

A: Your receipt of more than one proxy card or vote instruction card may mean that you have multiple accounts with ETP’s transfer agent or with a bank, brokerage firm or other nominee. If voting by mail, please sign and return all proxy cards or vote instruction cards to ensure that all of your ETP common units are voted. Each proxy card or vote instruction card represents a distinct number of units and it is the only means by which those particular units may be voted by proxy.

Q: Is completion of the merger subject to any conditions?

A: Yes. In addition to the adoption of the merger agreement by the holders of at least a majority of the outstanding ETP common units and at least a majority of the outstanding ETP common units held by unaffiliated ETP common unitholders, completion of the merger requires the receipt of the necessary governmental clearances, the issuance by ETE of the ETE Class A Units to ETE GP and the satisfaction or, to the extent permitted by applicable law, waiver of the other conditions specified in the merger agreement.

Q: When do you expect to complete the merger?

A: ETE and ETP are working towards completing the merger promptly. ETE and ETP currently expect to complete the merger shortly following the conclusion of the special meeting, subject to receipt of the ETP common unitholder approval, regulatory approvals and clearances and other usual and customary closing conditions; however, no assurance can be given as to when, or if, the merger will occur.

Q: What are the expected U.S. federal income tax consequences to an ETP unitholder as a result of the transactions contemplated by the merger agreement?

A: No gain or loss should be recognized by a holder of ETP common units solely as a result of the receipt of the merger consideration, other than (i) the difference between the deemed assumption by ETE of such ETP common unitholder’s share of any ETP liabilities that are treated as part of a “disguised sale” under Section 707 of the Internal Revenue Code of 1986, as amended (the “Code”), and any basis allocable to the portion of such ETP common unitholder’s ETP common units deemed sold as part of the “disguised sale” and (ii) any net decrease in such ETP common unitholder’s share of partnership liabilities pursuant to Section 752 of the Code (as adjusted for any nonrecourse liabilities taken into account as part of a “disguised sale”) in excess of such ETP common unitholder’s remaining adjusted tax basis. The amount and effect of any gain that may be recognized by holders of ETP common units will depend on such unitholder’s particular situation, including the ability of such unitholder to utilize any suspended passive losses.

Further, while we generally do not expect the ETP common unitholders to be subject to withholding obligations as a result of the transactions contemplated by the merger agreement, an ETP common unitholder whose ETE common units are deemed to be sold to fulfill its withholding obligations should recognize gain equal to the excess of the fair market value of the ETE common units which are deemed to be sold over the ETP common unitholder’s adjusted tax basis in such ETE common units.

For additional information, please read “Material U.S. Federal Income Tax Consequences of the Merger—Tax Consequences of the Merger to ETP and ETP Common Unitholders” and “Risk Factors—Risk Factors Relating to the Merger.”

Q: What are the expected U.S. federal income tax consequences for an ETP common unitholder of the ownership of ETE common units after the merger is completed?

A: Each ETP common unitholder who becomes a holder of ETE common units as a result of the merger will, as is the case for existing ETE common unitholders, be allocated such unitholder’s distributive share of ETE’s income, gains, losses, deductions and credits. In addition to U.S. federal income taxes, such a holder will

8

be subject to other taxes, including state and local income taxes, unincorporated business taxes, and estate, inheritance or intangibles taxes that may be imposed by the various jurisdictions in which ETE conducts business or owns property following the merger, or in which the unitholder is a resident. Please read “Material U.S. Federal Income Tax Consequences of ETE Common Unit Ownership.”

Q: How many Schedules K-1 will I receive for 2018 if I am an ETP common unitholder?

A: If you are a holder of ETP common units, you will receive two Schedules K-1, one from ETP, which will describe your share of ETP’s income, gain, loss and deduction for the portion of the tax year that you held ETP common units prior to the effective time, and one from ETE, which will describe your share of ETE’s income, gain, loss and deduction for the portion of the tax year you held ETE common units following the effective time.

ETP expects to furnish a Schedule K-1 to each ETP common unitholder within 90 days of the end of the calendar year in which the closing occurs, and ETE expects to furnish a Schedule K-1 to each ETE common unitholder within 90 days of the closing of ETE’s taxable year on December 31, 2018.

Q: What do I need to do now?

A: Carefully read and consider the information contained in and incorporated by reference into this proxy statement/prospectus, including its annexes. Then, please submit your proxy or vote your ETP common units in accordance with the instructions described above.

If you hold ETP common units through a bank, broker or other nominee, please instruct your bank, broker or nominee to vote your common units by following the instructions that the bank, broker or nominee provides to you with these materials.

Q: Should I send in my unit certificates now?

A: No. ETP common unitholders should not send in their unit certificates at this time. After completion of the merger, ETE’s exchange agent will send you a letter of transmittal and instructions for exchanging your ETP common units for the merger consideration.

Q: Are holders of ETP common units entitled to dissenters’ rights or appraisal rights?

A: No. Neither dissenters’ rights nor appraisal rights are available in connection with the merger under the Delaware Revised Uniform Limited Partnership Act (the “Delaware LP Act”), the merger agreement or the Fourth Amended and Restated Agreement of Limited Partnership of Energy Transfer Partners, L.P., as amended (the “ETP partnership agreement”).

Q: Whom should I call with questions?

A: ETP common unitholders who have questions about the merger or the special meeting, or desire additional copies of this proxy statement/prospectus or additional proxy cards or voting instruction forms should contact MacKenzie Partners, Inc., ETP’s proxy solicitor, at:

RISK FACTORS

In addition to the other information included and incorporated by reference into this proxy statement/prospectus, including the matters addressed in the section titled “Cautionary Statement Regarding Forward-Looking Statements,” you should carefully consider the following risks before deciding whether to vote for the adoption of the merger agreement and the transactions contemplated thereby. You should also read and carefully consider the risks associated with each of ETE and ETP and their respective businesses. These risks can be found in ETE’s and ETP’s respective Annual Reports on Form 10-K for the year ended December 31, 2017 as updated by any subsequent Quarterly Reports on Form 10-Q and Current Reports on Form 8-K, which are filed with the SEC and incorporated by reference into this proxy statement/prospectus. For further information regarding the documents incorporated into this proxy statement/prospectus by reference, please see the section titled “Where You Can Find More Information.” Realization of any of the risks described below, any of the events described under “Cautionary Statement Regarding Forward-Looking Statements” or any of the risks or events described in the documents incorporated by reference could have a material adverse effect on ETE’s, ETP’s or the combined organization’s businesses, financial condition, cash flows and results of operations and could result in a decline in the trading prices of their respective common units.

Risk Factors Relating to the Merger

Because the market price of ETE common units will fluctuate prior to the consummation of the merger, ETP common unitholders cannot be sure of the market value of the ETE common units they will receive as merger consideration relative to the value of ETP common units they exchange.

The market value of the merger consideration that ETP common unitholders will receive in the merger will depend on the trading price of ETE’s common units at the closing of the merger. The exchange ratio that determines the number of ETE common units that ETP common unitholders will receive as consideration in the merger is fixed. This means that there is no mechanism contained in the merger agreement that would adjust the number of ETE common units that ETP common unitholders will receive as the merger consideration based on any decreases or increases in the trading price of ETE common units. Unit price changes may result from a variety of factors (many of which are beyond ETE’s or ETP’s control), including:

Because the merger will be completed after the special meeting, at the time of the meeting, you will not know the exact market value of the ETE common units that you will receive upon completion of the merger. If ETE’s common unit price at the closing of the merger is less than ETE’s common unit price on the date on which the merger agreement was signed, then the market value of the merger consideration received by ETP common unitholders will be less than contemplated at the time the merger agreement was signed.

The fairness opinion rendered to the ETP Conflicts Committee by Barclays was based on Barclays’ financial analysis and considered factors such as market and other conditions then in effect, financial forecasts and other information made available to Barclays as of the date of the opinion. As a result, the opinion does not reflect changes in events or circumstances after the date of such opinion. The ETP Conflicts Committee has not obtained, and does not expect to obtain, an updated fairness opinion from Barclays reflecting changes in circumstances that may have occurred since the signing of the merger agreement.

The fairness opinion rendered to the ETP Conflicts Committee by Barclays was provided in connection with, and at the time of, the evaluation of the merger and the merger agreement by the ETP Conflicts Committee.

30

The opinion was based on the financial analyses performed, which considered market and other conditions then in effect, the Unaudited Financial Projections (dated June 5, 2018) and other information made available to Barclays as of the date of the opinion, which may have changed, or may change, after the date such information was prepared or after the date of the opinion. The ETP Conflicts Committee has not obtained an updated opinion from Barclays following the date of the merger agreement and does not expect to obtain an updated opinion prior to completion of the merger. Changes in the operations and prospects of ETE or ETP, general market and economic conditions and other factors that may be beyond the control of ETE and ETP, and on which the fairness opinion was based, may have altered the value of ETE or ETP or the prices of ETE common units or ETP common units since the date of such opinion, or may alter such values and prices by the time the merger is completed. The opinion does not speak as of any date other than the date of the opinion. For a description of the opinion that Barclays rendered to the ETP Conflicts Committee, please refer to “The Merger—Opinion of the Financial Advisor to the ETP Conflicts Committee.”

ETP and ETE may be targets of securities class action and derivative lawsuits, which could result in substantial costs and may delay or prevent the completion of the merger.

Securities class action lawsuits and derivative lawsuits are often brought against companies that have entered into merger agreements in an effort to enjoin the merger or seek monetary relief from ETP or ETE. Even if the lawsuits are without merit, defending against these claims can result in substantial costs and divert management time and resources. ETP and ETE cannot predict the outcome of these lawsuits, or others, nor can they predict the amount of time and expense that will be required to resolve such litigation. An unfavorable resolution of any such litigation surrounding the merger could delay or prevent its consummation. In addition, the costs defending the litigation, even if resolved in ETP’s or ETE’s favor, could be substantial and such litigation could distract ETP and ETE from pursuing the consummation of the merger and other potentially beneficial business opportunities.

Maintaining credit ratings is under the control of ratings agencies, which are independent third parties. There can be no assurances that the combined partnership will qualify for an investment-grade credit rating, and the failure to qualify for an investment-grade credit rating could negatively impact the combined partnership’s access to capital and costs of doing business.

In connection with the completion of the merger, ratings agencies may reevaluate ETE’s and ETP’s credit ratings. ETE and ETP expect that the combined partnership will qualify for an investment-grade credit rating consistent with ETP’s current rating; however, credit rating agencies perform independent analysis when assigning credit ratings and there can be no assurances that such ratings will be achieved in connection with the merger or maintained in the future. The analysis includes a number of criteria including, but not limited to, business composition, market and operational risks, as well as various financial tests. The combined company’s ratings upon completion of the merger will reflect each rating organization’s opinion of the combined company’s financial strength, operating performance and ability to meet the obligations associated with its securities. In addition, the trading market for ETE’s and ETP’s securities depends, in part on the research and reports that third-party securities analysts publish about ETE and ETP and the industry in which they participate. In connection with the completion of the merger, one or more of these analysts could downgrade ETE or ETP securities or issue other negative commentary about ETE or ETP and the industry in which they participate, which could cause the trading price of such securities to decline.

Failure to qualify for an investment-grade credit rating or a downgrade may increase ETE’s and ETP’s cost of borrowing, may negatively impact ETE’s and ETP’s ability to raise additional debt capital, may negatively impact ETE’s and ETP’s ability to successfully compete, and may negatively impact the willingness of counterparties to deal with ETE and ETP, each of which could have a material adverse effect on the business, financial condition, results of operations and cash flows of ETE and ETP, as well as the market price of their respective securities.

31

Credit rating agencies continue to review the criteria for industry sectors and various debt ratings on an ongoing basis and may make changes to those criteria from time to time. Ratings are subject to revision or withdrawal at any time by the rating agencies. The credit rating of the combined company will be subject to ongoing evaluation by credit rating agencies, and downgrades in the combined company’s ratings could adversely affect the combined company’s business, cash flows, financial condition, operating results and share and debt prices.

ETP’s and ETE’s financial estimates are based on various assumptions that may not prove to be correct.

The financial estimates set forth in the forecast included under “The Merger—Unaudited Financial Projections of ETE, ETP and the Combined Partnership” are based on assumptions of, and information available to, ETP and ETE, as of June 5, 2018, the time they were prepared. Neither ETP nor ETE knows whether such assumptions will prove correct. Any or all of such estimates may not necessarily be realized. Such estimates can be adversely affected by inaccurate assumptions or by known or unknown risks and uncertainties, many of which are beyond ETP’s and ETE’s control. Many factors mentioned in this proxy statement/prospectus, including the risks outlined in this “Risk Factors” section and the events or circumstances described under “Cautionary Statement Regarding Forward-Looking Statements,” will be important in determining ETP’s and ETE’s future results. As a result of these contingencies, actual future results may vary materially from ETP’s and ETE’s estimates. In view of these uncertainties, the inclusion of ETP’s and ETE’s financial estimates in this proxy statement/prospectus is not and should not be viewed as a representation that the forecast results will be achieved.

The Unaudited Financial Projections were not prepared with a view toward public disclosure, and such financial estimates were not prepared with a view toward compliance with published guidelines of any regulatory or professional body. Further, any forward-looking statement speaks only as of the date on which it is made, and ETP and ETE undertake no obligation, other than as required by applicable law, to update their respective financial estimates herein to reflect events or circumstances after the date those financial estimates were prepared or to reflect the occurrence of anticipated or unanticipated events or circumstances.

The Unaudited Financial Projections included in this proxy statement/prospectus have been prepared by, and are the responsibility of, ETP and ETE individually. Moreover, neither ETP’s or ETE’s independent accountants, Grant Thornton LLP, nor any other independent accountants, have compiled, examined or performed any procedures with respect to the Unaudited Financial Projections contained herein, nor have they expressed any opinion or any other form of assurance on such information or its achievability, and, accordingly, Grant Thornton LLP assumes no responsibility for, and disclaims any association with, the Unaudited Financial Projections. The reports of Grant Thornton LLP incorporated by reference herein relate exclusively to the historical audited financial information of the entities named in those reports and do not cover any other information in this proxy statement/prospectus and should not be read to do so. See “The Merger—Unaudited Financial Projections of ETE, ETP and the Combined Partnership” for more information.

Directors and executive officers of ETP have certain interests that are different from those of ETP unitholders generally.

Directors and executive officers of ETP are parties to agreements or participants in other arrangements that give them interests in the merger that may be different from, or in addition to, your interests as a unitholder of ETP. In addition, certain of the directors and executive officers of ETP are also directors or executive officers at ETE, and each of the directors of ETP is appointed by ETE, as the sole member of ETP Managing GP. These and other different interests are described under “The Merger—Interests of Directors and Executive Officers of ETP in the Merger.” You should consider these interests in voting on the merger.

32

The ETP partnership agreement limits the duties of ETP GP to ETP common unitholders and restricts the remedies available to unitholders for actions taken by ETP GP that might otherwise constitute breaches of its duties.

ETP Managing GP, the general partner of ETP GP, which is the general partner of ETP, is owned by ETE. In light of potential conflicts of interest between ETE and ETP GP, on the one hand, and ETP and the ETP common unitholders, on the other hand, the ETP Board submitted the merger and related matters to the ETP Conflicts Committee for, among other things, review, evaluation, negotiation and possible approval of a majority of its members, which is referred to as “Special Approval” in the ETP partnership agreement and this proxy statement/prospectus. In addition, the merger is conditioned upon the approval of at least a majority of the unaffiliated ETP common unitholders. Under the ETP partnership agreement:

The ETP Conflicts Committee reviewed, negotiated and evaluated the merger agreement, the merger and related matters on behalf of the ETP common unitholders (other than ETE and its affiliates) and ETP. Among other things, the ETP Conflicts Committee unanimously determined in good faith that the merger agreement and the transactions contemplated thereby, including the merger, are in the best interests of ETP and the unaffiliated ETP common unitholders, approved the merger agreement and the transactions contemplated thereby, including the merger, and recommended the approval of the merger agreement and the transactions contemplated thereby, including the merger, to the ETP Board.

The duties of ETP GP, the ETP Board and the ETP Conflicts Committee to ETP common unitholders in connection with the merger are substantially limited by the ETP partnership agreement.

ETE common unitholders have limited voting rights and are not entitled to elect ETE’s general partner or the directors of ETE’s general partner. Following the closing, the ETE Class A Units issued to ETE GP concurrently with closing would, together with the ETE common units owned by ETE GP, result in ETE GP and its affiliates maintaining the same relative voting power following the merger as they have prior to the merger, until such time as Mr. Warren is no longer an officer or director of ETE GP.

Unlike the holders of common stock in a corporation, ETE common unitholders have only limited voting rights on matters affecting ETE’s business, and therefore limited ability to influence ETE management’s decisions regarding its business. ETE common unitholders did not elect its general partner and will have no right to elect its general partner or the officers or directors of its general partner on an annual or other continuing basis. In addition, on matters where ETE common unitholders are entitled to vote, the ETE partnership agreement generally permits ETE GP and its affiliates to vote their ETE common units on such matters, together with unaffiliated ETE unitholders, as a single class. For example, ETE GP may only be removed as the general partner by the affirmative vote of holders of 66 2/3% of the ETE common units (including ETE GP and its affiliates), voting together as a single class. As of August 1, 2018, ETE GP and its affiliates collectively own approximately 31% of the outstanding ETE common units.

In connection with the closing of the merger and the issuance of the merger consideration to former ETP common unitholders, the percentage ownership of ETE GP and its affiliates of ETE common units is expected to

33

be diluted to approximately 13.5%. However, at the closing of the merger, ETE will issue to ETE GP a number of ETE Class A Units necessary to ensure that ETE GP and its affiliates maintain the same relative voting power following the merger as they have prior to the merger. ETE Class A Units will not be entitled to distributions, will not have any economic attributes (other than the entitlement to $100 in the aggregate upon liquidation) and will not be convertible or exchangeable for ETE common units, but will generally vote as a single class with ETE common units. For so long as Mr. Warren continues as a director or officer of ETE GP, upon issuance of additional ETE common units following the merger, ETE will also issue additional ETE Class A Units to ETE GP such that the ETE Class A Units will continue to represent, in the aggregate, the same voting interest as they represent upon closing of the merger. The existence of the ETE Class A Units from and after closing of the merger will therefore, in certain circumstances, reduce the voting power represented by an ETE common unit compared to a scenario in which the ETE Class A Units had not been issued.

ETE common units to be received by ETP common unitholders as a result of the merger have different rights than ETP common units.

Following completion of the merger, ETP common unitholders will no longer hold ETP common units, but will instead be common unitholders of ETE. There are important differences between the rights of ETP common unitholders and the rights of ETE common unitholders. See “Comparison of Rights of ETE Common Unitholders and ETP Common Unitholders” for a discussion of the different rights associated with ETE common units and ETP common units.

The number of outstanding ETE common units will increase as a result of the merger, which could make it more difficult for ETE to pay the current level of quarterly distributions.

As of July 31, 2018, there were more than 1,158 million ETE common units outstanding. ETE expects to issue approximately 1.5 billion common units in connection with the merger. Accordingly, the aggregate dollar amount required to pay the current per unit quarterly distribution on all ETE common units will increase, which could increase the likelihood that ETE will not have sufficient funds to pay the current level of quarterly distributions to all ETE unitholders. Using a $0.305 per ETE common unit distribution (the amount ETE paid with respect to the second fiscal quarter of 2018 on August 20, 2018 to holders of record as of August 6, 2018), the aggregate cash distribution paid to ETE unitholders totaled approximately $354 million, including a distribution of $1 million to ETE GP in respect of its general partner interest. Using the same $0.305 per ETE common unit distribution, the combined pro forma ETE distribution with respect to the second fiscal quarter of 2018, had the merger been completed prior to such distribution, would have resulted in total cash distributions of approximately $811 million, including a distribution of $1 million to ETE GP in respect of its general partner interest.

ETE and ETP will incur substantial transaction-related costs in connection with the merger, including fees paid to legal, financial and accounting advisors, filing fees and printing costs.

ETE and ETP expect to incur a number of non-recurring transaction-related costs associated with completing the merger. These fees and costs will be substantial. Non-recurring transaction costs include, but are not limited to, fees paid to legal, financial and accounting advisors, filing fees and printing costs. Thus, any net benefit of the merger may not be achieved in the near term, the long term or at all.

The merger is subject to conditions, including certain conditions that may not be satisfied on a timely basis, if at all. Failure to complete the merger, or significant delays in completing the merger, could negatively affect the trading prices of ETE common units and ETP common units and the future business and financial results of ETE and ETP.

The completion of the merger is subject to a number of conditions, some of which are beyond the parties’ control. In addition, ETE and ETP can agree not to consummate the merger even if the ETP common unitholders approve the merger proposal and the conditions to the closing of the merger are otherwise satisfied.

34

The completion of the merger is not assured and is subject to risks, including the risk that the closing conditions are not satisfied, including that the approval of the merger by ETP common unitholders or by governmental agencies is not obtained or the occurrence of a material adverse change to the business or results of operations of ETE and ETP. The failure to satisfy conditions to the merger may prevent or delay the merger or otherwise result in the merger not occurring. The failure of the completion of the merger, or any significant delays in completing the merger, could cause the combined company not to realize, or delay the realization of, some or all of the benefits that the combined company expects to achieve from the merger, including those relating to the trading prices of ETE common units and the respective future business and financial results of ETE and ETP, which could be negatively affected, and each of which are subject to risks, including the following:

ETP is subject to provisions in the merger agreement that limit its ability to pursue alternatives to the merger, which could discourage a potential competing acquirer of ETP from making a favorable alternative transaction proposal and, in specified circumstances under the merger agreement, would require ETP to reimburse up to $30.0 million of ETE’s out-of-pocket expenses and pay a termination fee to ETE of $750.0 million less any previous expense reimbursements.

Under the merger agreement, ETP is restricted from entering into alternative transactions. Unless and until the merger agreement is terminated, subject to specified exceptions (which are discussed in more detail in “Proposal 1: The Merger Agreement—No Solicitation by ETP of Alternative Proposals”), ETP is restricted from soliciting, initiating, knowingly facilitating, knowingly encouraging or knowingly inducing or taking any other action intended to lead to any inquiries or any proposals that constitute or could reasonably be expected to lead to a proposal or offer for a competing acquisition proposal with any person. In addition, ETP may not grant any waiver or release of any standstill or similar agreement with respect to any units of ETP or any of its subsidiaries. Under the merger agreement, in the event of a potential change by the ETP Board of its recommendation with respect to the proposed merger in light of a superior proposal, ETP must provide ETE with five calendar days’ notice to allow ETE to propose an adjustment to the terms and conditions of the merger agreement. These provisions could discourage a third party that may have an interest in acquiring all or a significant part of ETP from considering or proposing that acquisition, even if such third party were prepared to pay consideration with a higher per unit market value than the merger consideration, or might result in a potential competing acquirer of ETP proposing to pay a lower price than it would otherwise have proposed to pay because of the added expense of the termination fee that may become payable in specified circumstances.

If the merger agreement is terminated under specified circumstances, including due to an adverse recommendation change having occurred or ETP entering into an agreement relating to a superior proposal, ETP will be required to pay ETE a termination fee of $750.0 million, less any expenses of ETE previously reimbursed by ETP. If the merger agreement is terminated under specified circumstances, including if the ETP unitholder approval is not obtained or if ETP breaches certain of its obligations under the merger agreement, then ETP will be required to pay all of the reasonably documented out-of-pocket expenses incurred by ETE and its affiliates in

35

connection with the merger agreement and the transactions contemplated thereby, up to a maximum amount of $30.0 million. Following payment of the termination fee or the reimbursement of expenses, as applicable, ETP will not be obligated to pay any additional expenses incurred by ETE or its affiliates. Please read “Proposal 1: The Merger Agreement—Expenses” and “—Termination Fee.” If such a termination fee is payable, the payment of this fee could have material and adverse consequences to the financial condition and operations of ETP. For a discussion of the restrictions on soliciting or entering into an alternative transaction and the ability of the ETP Board to change its recommendation, see “Proposal 1: The Merger Agreement—No Solicitation by ETP of Alternative Proposals” and “—Change in ETP Board Recommendation.”

If a governmental authority asserts objections to the merger, ETE and ETP may be unable to complete the merger or, in order to do so, ETE and ETP may be required to comply with material restrictions or satisfy material conditions.

The closing of the merger is subject to the condition that there is no law, injunction, judgment or ruling by a governmental authority in effect enjoining, restraining, preventing or prohibiting the merger contemplated by the merger agreement. If a U.S. or foreign governmental authority asserts objections to the merger, ETE or ETP may be required to divest assets or accept other remedies in order to complete the merger. There can be no assurance as to the cost, scope or impact of the actions that may be required to address any governmental authority objections to the merger. If ETE or ETP takes such actions, it could be detrimental to it or to the combined organization following the consummation of the merger. Furthermore, these actions could have the effect of delaying or preventing completion of the proposed merger or imposing additional costs on or limiting the revenues or cash available for distribution of the combined organization following the consummation of the merger. See “Proposal 1: The Merger Agreement—Regulatory Matters.”

Additionally, state attorneys general or other state or local regulators could seek to block, rescind or challenge the merger as they deem necessary or desirable in the public interest at any time, including after completion of the transaction. In addition, in some circumstances, a third party could initiate a private action under antitrust laws challenging or seeking to enjoin or rescind the merger, before or after it is completed. ETE may not prevail and may incur significant costs in defending or settling any action under the antitrust laws.

ETE and ETP are subject to contractual interim operating restrictions while the proposed merger is pending, which could adversely affect each party’s business and operations.

Under the terms of the merger agreement, each of ETE and ETP is subject to certain restrictions on the conduct of its business prior to completing the merger, which may adversely affect its ability to execute certain of its business strategies. Such limitations could negatively affect each party’s businesses and operations prior to the completion of the merger. For a discussion of these restrictions, see “Proposal 1: The Merger Agreement—Conduct of Business Pending the Consummation of the Merger.”

If the merger is approved by ETP common unitholders, the date on which ETP common unitholders will receive the merger consideration is uncertain.

As described in this proxy statement/prospectus, completing the proposed merger is subject to several conditions, not all of which are controllable or waivable by ETE or ETP. Accordingly, if the proposed merger is approved by ETP common unitholders, the date on which ETP common unitholders will receive the merger consideration depends on the completion date of the merger, which is uncertain.

ETP common unitholders will have a reduced ownership in the combined organization after the merger as compared to their ownership of ETP.

When the merger occurs, each ETP common unitholder that receives ETE common units will become a common unitholder of ETE with a percentage ownership of the combined organization that is smaller than such

36

unitholder’s percentage ownership of ETP prior to the merger. Assuming that the merger had been completed on August 1, 2018, current ETP common unitholders would have owned approximately 56% of the combined partnership based on the number of ETP common units and ETE common units outstanding at that date.

No ruling has been obtained with respect to the U.S. federal income tax consequences of the merger.

No ruling has been or will be requested from the IRS with respect to the U.S. federal income tax consequences of the merger. Instead, ETE and ETP are relying on the opinions of their respective counsel as to the U.S. federal income tax consequences of the merger, and such counsel’s conclusions may not be sustained if challenged by the IRS. Please read “Material U.S. Federal Income Tax Consequences of the Merger.”

The expected U.S. federal income tax consequences of the merger are dependent upon ETE and ETP being treated as partnerships for U.S. federal income tax purposes.

If either ETE or ETP were to be treated as a corporation for U.S. federal income tax purposes, the consequences of the merger would be materially different. If ETE were to be treated as a corporation for U.S. federal income tax purposes, the merger would likely be a fully taxable transaction to ETP common unitholders.

ETP common unitholders could recognize taxable income or gain for U.S. federal income tax purposes as a result of the merger.

For U.S. federal income tax purposes, each holder of ETP common units (other than ETE and its affiliates) will be deemed to contribute its ETP common units to ETE in exchange for ETE common units and the deemed assumption by ETE of each such ETP common unitholder’s share of ETP’s liabilities. The deemed assumption by ETE of such liabilities will trigger gain or loss to such ETP common unitholders to the extent that such amounts are treated as a “disguised sale” of property, rather than as a non-taxable contribution of ETP common units to ETE in exchange for ETE common units. In addition, as a result of the merger, the holders of ETP common units who receive ETE common units will become limited partners of ETE and will be allocated a share of ETE’s nonrecourse liabilities. Each holder of ETP common units will be treated as receiving a deemed cash distribution equal to the net reduction in the amount of nonrecourse liabilities allocated to such ETP common unitholder (as adjusted to take into account any nonrecourse liabilities included in the Section 707 Consideration (as defined below)). If the amount of such deemed cash distribution received by a holder of ETP common units exceeds such ETP common unitholder’s tax basis in ETE common units immediately after the merger, after reducing such tax basis to account for any tax basis allocable to the portion of such unitholder’s ETP common units deemed sold as a result of the receipt of Section 707 Consideration, such ETP common unitholder will recognize gain in an amount equal to such excess. Further, while under current law we generally do not expect the ETP common unitholders to be subject to withholding obligations as a result of the transactions contemplated by the merger agreement, an ETP common unitholder whose ETE common units are deemed to be sold to fulfil its withholding obligations should recognize gain equal to the excess of the fair market value of the ETE common units which are deemed to be sold over the ETP common unitholder’s adjusted tax basis in such ETE common units. The amount and effect of any gain that may be recognized by holders of ETP common units will depend on such unitholder’s particular situation, including the ability of such unitholder to utilize any suspended passive losses.

Unless expressly stated otherwise, forward-looking statements are based on the expectations and beliefs of the respective managements of ETE and ETP, based on information currently available, concerning future events affecting ETE and ETP. Although ETE and ETP believe that these forward-looking statements are based on reasonable assumptions, they are subject to uncertainties and factors related to ETE’s and ETP’s operations and business environments, all of which are difficult to predict and many of which are beyond ETE’s and ETP’s control. Any or all of the forward-looking statements in this proxy statement/prospectus may turn out to be wrong. They can be affected by inaccurate assumptions or by known or unknown risks and uncertainties. The foregoing list of factors should not be construed to be exhaustive. Many factors mentioned in this proxy statement/prospectus, including the risks outlined under the caption “Risk Factors” contained in ETE’s and ETP’s Exchange Act reports incorporated herein by reference, will be important in determining future results, and actual future results may vary materially. There is no assurance that the actions, events or results of the forward-looking statements will occur, or, if any of them do, when they will occur or what effect they will have on ETE’s and ETP’s results of operations, financial condition, cash flows or distributions.

THE SPECIAL MEETING

ETP is providing this proxy statement/prospectus to its common unitholders in connection with the solicitation of proxies to be voted at the special meeting of common unitholders that ETP has called for, among other things, the purpose of holding a vote upon a proposal to adopt the merger agreement and the transactions contemplated thereby, including the merger, and at any adjournment or postponement thereof. This proxy statement/prospectus constitutes a proxy statement of ETP in connection with the special meeting of ETP common unitholders and a prospectus for ETE in connection with the issuance by ETE of its common units in connection with the merger. This proxy statement/prospectus is first being mailed to ETP’s common unitholders on or about September 11, 2018, and provides ETP common unitholders with the information they need to know to be able to vote or instruct their vote to be cast at the special meeting of ETP common unitholders.

Date, Time and Place

The special meeting will be held at the Hilton Dallas Park Cities Hotel, 5954 Luther Lane, Dallas, Texas 75225, on October 18, 2018, at 10:00 a.m., local time.

Purpose

At the special meeting, ETP common unitholders will be asked to vote solely on the following proposals:

Recommendation of the ETP Board

The ETP Board recommends, based on the recommendation of the ETP Conflicts Committee, that common unitholders of ETP vote:

The ETP Board has determined that the form, terms and provisions of the merger agreement and the transactions contemplated thereby, including the merger and the ETP LPA amendment, are advisable, fair and reasonable to and in the best interests of ETP and its common unitholders and the ETP Conflicts Committee has determined that the merger agreement and the merger are advisable and fair and reasonable to ETP, and in the best interests of ETP and the unaffiliated ETP common unitholders, and in each case, has approved the merger agreement and the merger. The ETP Board has resolved to recommend approval of the merger agreement and the transactions contemplated thereby to the ETP common unitholders. See “The Merger—Recommendation of the ETP Board; Reasons for the Merger.”

In considering the recommendation of the ETP Board with respect to the merger agreement and the transactions contemplated thereby, you should be aware that some or all of ETP’s directors and executive officers may have interests that are different from, or in addition to, the interests of ETP common unitholders more generally. See “The Merger—Interests of Directors and Executive Officers of ETP in the Merger.”

Record Date; Outstanding Units; Units Entitled to Vote

The record date for the special meeting is September 10, 2018. Only ETP common unitholders of record at the close of business on the record date will be entitled to receive notice of and to vote at the special meeting or any adjournment or postponement of the meeting.

43

As of the close of business on the record date of September 10, 2018, there were 1,167,186,967 ETP common units outstanding and entitled to vote at the meeting (including 30,681,980 ETP common units held by ETE and its affiliates). Each ETP common unit is entitled to one vote.

Pursuant to the ETP partnership agreement, if at any time any person or group (other than ETP GP and its affiliates, including ETE) beneficially owns 20% or more of any class of ETP units, such person or group loses voting rights on all of its units and such units will not be considered “outstanding.” This loss of voting rights does not apply to (i) any person or group who acquired 20% or more of any class of ETP units from ETP GP or its affiliates, (ii) any person or group who directly or indirectly acquired 20% or more of any class of ETP units from that person or group described in clause (i) provided ETP GP notified such transferee that such loss of voting rights did not apply, or (iii) any person or group who acquired 20% or more of any class of units issued by ETP with the prior approval of the ETP Board.

A complete list of ETP common unitholders entitled to vote at the special meeting will be available for inspection at ETP’s principal executive offices at 8111 Westchester Drive, Suite 600, Dallas, Texas 75225 during regular business hours for a period of no less than 10 days before the special meeting and at the place of the special meeting during the meeting.

Quorum

A quorum of ETP common unitholders represented in person or by proxy at the special meeting is required to vote on adoption of the merger agreement at the special meeting, but not to vote on approval of any adjournment of the meeting. The holders of at least a majority of the outstanding ETP common units must be represented in person or by proxy at the meeting in order to constitute a quorum. Any abstentions and broker non-votes will be counted in determining whether a quorum is present at the special meeting.

Required Vote

To adopt the merger agreement and the transactions contemplated thereby, including the merger, the holders of at least a majority of the outstanding ETP common units and at least a majority of the outstanding ETP common units held by unaffiliated ETP common unitholders must vote in favor of such adoption. ETP cannot complete the merger unless its common unitholders adopt the merger agreement and the transactions contemplated thereby. Because approval is based on the affirmative vote of at least a majority of the outstanding ETP common units (with and without ETP common units held by ETE and its affiliates), an ETP common unitholder’s failure to vote, an abstention from voting or a broker non-vote will have the same effect as a vote “AGAINST” adoption of the merger proposal.

If a quorum is present at the special meeting, to approve the adjournment of the meeting, if necessary, to solicit additional proxies if there are not sufficient votes to adopt the merger agreement at the time of the special meeting, holders of at least a majority of the outstanding ETP common units must vote in favor of the adjournment proposal. Therefore, if a quorum is present at the meeting, abstentions, broker non-votes and an ETP common unitholder’s failure to vote will have the same effect as a vote “AGAINST” approval of the adjournment proposal. If a quorum is not present at the special meeting, to approve the adjournment of the meeting, holders of at least a majority of the outstanding ETP common units represented thereat either in person or by proxy must vote in favor of the adjournment proposal. Therefore, if a quorum is not present, abstentions and broker non-votes will have the same effect as a vote “AGAINST” approval of the adjournment proposal, but an ETP common unitholder’s failure to vote will have no effect on the outcome of the adjournment proposal. In addition, the ETP partnership agreement allows ETP GP to also adjourn the meeting from time to time without the approval of ETP common unitholders.

Common Unit Ownership of and Voting by ETP’s and ETE’s Directors, Executive Officers and Affiliates

As of September 10, 2018, ETP’s directors and executive officers and their affiliates (excluding ETE and its subsidiaries) beneficially owned and had the right to vote 2,719,759 ETP common units at the special meeting,

44

which represent approximately 0.2% of the ETP common units entitled to vote at the special meeting. Additionally, ETE’s directors and executive officers and their affiliates (including ETE and its subsidiaries) beneficially owned and had the right to vote 30,681,980 ETP common units at the special meeting, which represent approximately 2.6% of the ETP common units entitled to vote at the special meeting. It is expected that ETP’s and ETE’s directors and executive officers will vote their ETP common units “FOR” the adoption of the merger agreement and the transactions contemplated thereby, including the merger, although none of them has entered into any agreement requiring them to do so. Additionally, under the terms of the merger agreement, ETE has agreed to vote all of the ETP common units owned beneficially or of record by ETE or its subsidiaries in favor of the approval of the merger agreement and the merger and the approval of any actions required in furtherance thereof.

Voting of Common Units by Holders of Record

If you are entitled to vote at the special meeting and hold your ETP common units in your own name, you can submit a proxy or vote in person by completing a ballot at the special meeting. However, ETP encourages you to submit a proxy before the special meeting even if you plan to attend the special meeting in order to ensure that your ETP common units are voted. A proxy is a legal designation of another person to vote your ETP common units on your behalf. If you hold units in your own name, you may submit a proxy for your ETP common units by:

When a common unitholder submits a proxy by telephone or through the Internet, his or her proxy is recorded immediately. ETP encourages its unitholders to submit their proxies using these methods whenever possible. If you submit a proxy by telephone or the Internet, please do not return your proxy card by mail.

All ETP common units represented by each properly executed and valid proxy received before the special meeting will be voted in accordance with the instructions given on the proxy. If an ETP common unitholder executes a proxy card without giving instructions, the ETP common units represented by that proxy card will be voted as the ETP Board recommends, which is:

Your vote is important. Accordingly, please submit your proxy by telephone, through the Internet or by mail, whether or not you plan to attend the meeting in person. Proxies must be received by 11:59 p.m., Eastern Time, on October 17, 2018. However, if the special meeting is adjourned to solicit additional proxies, the deadline may be extended.

Voting of Common Units Held in Street Name

If your ETP common units are held in an account at a bank, broker or through another nominee, you must instruct the bank, broker or other nominee on how to vote your ETP common units by following the instructions that the bank, broker or other nominee provides to you with these proxy materials. Most brokers offer the ability for unitholders to submit voting instructions by mail by completing a voting instruction card, by telephone and via the Internet.

45

If you do not provide voting instructions to your broker, your ETP common units will not be voted on any proposal on which your broker does not have discretionary authority to vote. This is referred to in this proxy statement/prospectus and in general as a broker non-vote. In these cases, the bank, broker or other nominee can register your ETP common units as being present at the special meeting for purposes of determining a quorum, but will not be able to vote your ETP common units on those matters for which specific authorization is required. Under the current rules of the NYSE, brokers do not have discretionary authority to vote on any of the proposals, including the merger proposal. A broker non-vote of an ETP common unit will have the same effect as a vote “AGAINST” the merger proposal and the adjournment proposal.

If you hold ETP common units through a bank, broker or other nominee and wish to vote your ETP common units in person at the special meeting, you must obtain a proxy from your bank, broker or other nominee and present it to the inspector of election with your ballot when you vote at the special meeting.

Revocability of Proxies; Changing Your Vote

You may revoke your proxy and/or change your voting instructions at any time before your proxy is voted at the special meeting. If you are an ETP common unitholder of record, you can do this by:

If you hold your ETP common units through a bank, broker or other nominee, you must follow the directions you receive from your bank, broker or other nominee in order to revoke your proxy or change your voting instructions.

Solicitation of Proxies

This proxy statement/prospectus is furnished in connection with the solicitation of proxies by the ETP Board to be voted at the special meeting. ETP will bear all costs and expenses in connection with the solicitation of proxies. ETP has engaged MacKenzie Partners, Inc. to assist in the solicitation of proxies for the meeting and ETP estimates it will pay MacKenzie Partners, Inc. a fee of approximately $50,000 for these services. ETP has also agreed to reimburse MacKenzie Partners, Inc. for reasonable out-of-pocket expenses and disbursements incurred in connection with the proxy solicitation and to indemnify MacKenzie Partners, Inc. against certain losses, costs and expenses. In addition, ETP may reimburse brokerage firms and other persons representing beneficial owners of ETP common units for their reasonable expenses in forwarding solicitation materials to such beneficial owners. Proxies may also be solicited by certain of ETP’s directors, officers and employees by telephone, electronic mail, letter, facsimile or in person, but no additional compensation will be paid to them.

Common Unitholders Should Not Send Unit Certificates with Their Proxies.

ETP common unitholders should not send in their unit certificates at this time. After completion of the merger, ETE’s exchange agent will send you a letter of transmittal and instructions for exchanging your ETP common units for the merger consideration.

No Other Business

Under the ETP partnership agreement, the business to be conducted at the special meeting will be limited to the purposes stated in the notice to ETP common unitholders provided with this proxy statement/prospectus.

46

Adjournments

Adjournments may be made for the purpose of, among other things, soliciting additional proxies. If a quorum exists, an adjournment may be made from time to time with approval of the holders of at least a majority of the outstanding ETP common units. If a quorum does not exist, an adjournment may be made from time to time with the approval of the holders of at least a majority of the ETP common units entitled to vote at such meeting and represented thereat either in person or by proxy. ETP is not required to notify common unitholders of any adjournment of 45 days or less if the time and place of the adjourned meeting are announced at the meeting at which the adjournment is taken, unless after the adjournment a new record date is fixed for the adjourned meeting. At any adjourned meeting, ETP may transact any business that it might have transacted at the original meeting, provided that a quorum is present at such adjourned meeting. Proxies submitted by ETP common unitholders for use at the special meeting will be used at any adjournment or postponement of the meeting. References to the special meeting in this proxy statement/prospectus are to such special meeting as adjourned or postponed.

THE MERGER

This section of the proxy statement/prospectus describes the material aspects of the proposed merger. This section may not contain all of the information that is important to you. You should carefully read this entire proxy statement/prospectus and the documents incorporated herein by reference, including the full text of the merger agreement, for a more complete understanding of the merger. A copy of the merger agreement is attached as Annex A hereto. In addition, important business and financial information about each of ETE and ETP is included in or incorporated into this proxy statement/prospectus by reference. See “Where You Can Find More Information.”

Effect of the Merger

Subject to the terms and conditions of the merger agreement and in accordance with Delaware law, the merger agreement provides for the merger of ETE Merger Sub with and into ETP. ETP, which is sometimes referred to following the merger as the surviving entity, will survive the merger, and the separate limited liability company existence of ETE Merger Sub will cease. As a result of the merger and the transactions contemplated thereby, ETE will acquire all of the outstanding ETP common units that ETE and its subsidiaries do not already own. After the completion of the merger, the certificate of limited partnership of ETP in effect immediately prior to the effective time, as amended to reflect a change in its name to “Energy Transfer Operating, L.P.,” will be the certificate of limited partnership of the surviving entity, until amended in accordance with its terms and applicable law. In addition, immediately prior to the effective time, the ETP partnership agreement will be amended pursuant to the ETP LPA amendment to, among other things, reflect the conversion of ETP’s incentive distribution rights into ETP common units, the cancellation of the Class I Units and Class J Units, and the conversion of the economic general partner interest in ETP to a non-economic general partner interest in ETP and ETP common units. At the effective time, the ETP partnership agreement, as amended by the ETP LPA amendment, will remain unchanged and will be the agreement of limited partnership of the surviving entity from and after the effective time, until amended in accordance with its terms and applicable law.

The merger agreement provides that, at the effective time, each ETP common unit issued and outstanding as of immediately prior to the effective time (other than any ETP common units owned by ETE or any subsidiary of ETE) will be converted into the right to receive 1.28 ETE common units. Each ETP common unit owned by ETE and its subsidiaries and issued and outstanding immediately prior to the effective time (including any ETP common units issued in connection with the pre-closing transactions described below) will remain unchanged and remain outstanding. In addition, each Class E Unit, Class G Unit, Class K Unit of ETP, as well as each Series A Preferred Unit, Series B Preferred Unit, Series C Preferred Unit and Series D Preferred Unit of ETP, that is issued and outstanding as of immediately prior to the effective time will, at the effective time, continue to be issued and outstanding and represent limited partner interests in ETP.

Because the exchange ratio was fixed at the time the merger agreement was executed and because the market value of ETE common units and ETP common units will fluctuate prior to the consummation of the merger, ETP common unitholders cannot be sure of the value of the merger consideration they will receive relative to the value of ETP common units that they are exchanging. For example, decreases in the market value of ETE common units will negatively affect the value of the merger consideration that ETP common unitholders receive, and increases in the market value of ETP common units may mean that the merger consideration that such unitholders receive will be worth less than the market value of the ETP common units that they are exchanging. See “Risk Factors—Risk Factors Relating to the Merger.”

ETE will not issue any fractional units in the merger. Instead, each holder of ETP common units that are converted pursuant to the merger agreement who otherwise would have received a fraction of an ETE common unit will be entitled to receive a whole ETE common unit.

At the effective time, each unvested award of ETP restricted units or ETP restricted phantom units outstanding immediately prior to the effective time will, by virtue of the merger and without any action on the

48

part of the holder thereof, cease to relate to or represent a right to receive ETP common units and will be converted into the right to receive a comparable restricted equity award with respect to ETE common units, on the same terms and conditions as were applicable to the corresponding award of ETP (including the right to receive distribution equivalents with respect to such award), except that the number of ETE common units covered by each such comparable award will be equal to the number of ETP common units subject to the corresponding award of ETP multiplied by the exchange ratio, rounded up to the nearest whole unit.

Pre-Closing Transactions

Subject to the conditions to the merger being satisfied or waived (other than conditions that by their nature are to be satisfied at closing, but subject to the satisfaction or waiver of those conditions), ETE, ETP Managing GP and ETP will, and will cause their respective affiliates to, cause the following pre-closing transactions to occur immediately prior to the effective time in the order set forth below:

In connection with the closing of the merger, ETE has agreed to issue ETE Class A Units to ETE GP. The number of ETE Class A Units to be issued to ETE GP will allow ETE GP and its affiliates to retain their current voting interest in ETE following the completion of the merger. The ETE Class A Units will be entitled to vote together with the ETE common units, as a single class, on any matter for which the holders of ETE common units are entitled to vote, except as required by law. Additionally, without the approval of 66 2/3% of the ETE Class A Units, ETE may not take any action that disproportionately or materially adversely affects the rights, preferences or privileges of the ETE Class A Units or amend the terms thereof. Following the closing of the merger, for so long as Kelcy Warren is an officer or a director of ETE GP, upon the issuance by ETE of additional ETE common units or any securities that have voting rights that are pari passu with the ETE common units, ETE will issue to the holder of ETE Class A Units a number of additional ETE Class A Units such that the holder maintains a voting interest in ETE with respect to its ETE Class A Units that is identical to its voting interest in ETE with respect to its ETE Class A Units prior to such issuance. The ETE Class A Units will not be entitled to distributions and otherwise have no economic attributes, except that the ETE Class A Units in the aggregate will be entitled to an aggregate $100 distribution prior and in preference to any distribution of assets to the holders of other classes or series of securities of ETE upon any liquidation, dissolution or winding up of ETE. The ETE Class A Units are not convertible into, or exchangeable for, ETE common units. Without the prior

49

approval of a conflicts committee of the ETE Board, the ETE Class A Units may not be transferred to any person or entity, other than to Kelcy Warren, Ray Davis or to any trust, family partnership or family limited liability company the sole beneficiaries, partners or members of which are Kelcy Warren, Ray Davis or their respective relatives.

Background of the Merger

The senior management, the ETE Board and the ETP Board regularly review operational and strategic opportunities to maximize value for their respective investors. In connection with these reviews, the management and boards of directors of ETE and ETP from time to time evaluate potential transactions that would further their respective strategic objectives. Over the last year, ETE and ETP have considered potential simplification transactions in an effort to reduce ETP’s cost of capital in order to increase unitholder value for each of ETE and ETP.

During this period, management of ETE and ETP made public statements regarding their desire to pursue such a transaction when management believed that these objectives could be achieved. Management of ETE and ETP also discussed with the ETE Board and the ETP Board, respectively, that management was continuously evaluating the prospect of pursuing a simplification transaction. As the retention of investment grade ratings from the three credit rating agencies is a critical component of the overall cost of capital for funding capital projects by ETP, the consideration of a simplification transaction by ETE and ETP was dependent upon management’s belief that the combined partnership would be able to maintain the investment grade ratings currently applicable to ETP’s public debt. Management of ETE and ETP considered several alternative structures for a potential simplification before more seriously considering the acquisition of ETP by ETE based on a range of exchange ratios that could have the effect of providing to ETP common unitholders a premium to the current trading price of the ETP common units while reducing the aggregate amount of cash distributions that the combined partnership would make to its unitholders following a combination, assuming the combined partnership continued to pay distributions at the same rate ETE paid distributions prior to a combination. Management of ETE and ETP considered this structure as the most attractive alternative for achieving the objective of decreasing the combined partnership’s equity cost of capital and believed the structure would allow the combined partnership to satisfy the rating agency criteria and achieve an investment grade rating following the transaction. Based on these considerations, management of ETE and ETP determined that it would be appropriate for this transaction structure to be presented to the ETE Board and the ETP Board for their consideration.

On July 7, 2018, ETE contacted a representative of Latham & Watkins LLP (“Latham”) regarding the potential engagement of Latham as legal advisor to the ETE Board in considering potential simplification transactions.

On July 13, 2018, the ETE Board convened for an informational meeting with Thomas P. Mason, Executive Vice President and General Counsel of ETE, Thomas E. Long, Group Chief Financial Officer of ETE, and other members of ETE management attending as guests. At this meeting, the ETE Board and ETE management discussed various strategic alternatives that ETE management had been considering over the past several months to address the constraints on ETP’s cost of capital. In addition, the ETE Board discussed the necessity for ETE to establish a conflicts committee in the future to evaluate potential conflicts of interest in any proposed transaction.

On July 17, 2018, ETP contacted a representative of Vinson & Elkins L.L.P. (“V&E”) regarding the potential engagement of V&E as legal advisor to ETP in connection with a potential simplification transaction.

On July 21, 2018, the ETE Board held a meeting to discuss midstream market trends and various strategic alternatives with ETE senior management to simplify the Energy Transfer organizational structure. In particular, the ETE Board discussed the following alternatives: (i) an acquisition of ETP by ETE in a unit-for-unit transaction; (ii) an acquisition of ETE by ETP in a unit-for-unit transaction; (iii) a transaction in which ETE would convert its economic general partner interest into a non-economic general partner interest and agree to the cancellation of its

50

incentive distribution rights in ETP, in exchange for ETP common units; and (iv) a transaction in which ETE would agree to a reset of its incentive distribution rights in ETP, in exchange for ETP common units.

On July 24, 2018, the ETE Board held a meeting to discuss further the strategic alternatives considered at the meeting on July 21, 2018. After such discussion, the ETE Board determined that the potential acquisition by ETE of ETP would be the most beneficial alternative to both ETE and ETP, and authorized Kelcy Warren to submit a written proposal to ETP. The ETE Board also determined to establish the ETE Conflicts Committee and appointed as members Richard Brannon and Steven Anderson. The ETE Board delegated to the ETE Conflicts Committee the authority to, among other things, (i) review and evaluate the proposed transaction, (ii) negotiate the terms and conditions of the proposed transaction, and (iii) determine whether to approve the proposed transaction and to recommend approval of the proposed transaction to the ETE Board. The ETE Board also delegated to the Audit and Conflicts Committee of the ETE Board (the “ETE A&C Committee”), comprised of Mr. Brannon, Mr. Anderson and Mr. William Williams, the authority to review and evaluate the proposed transaction and to determine whether to approve the proposed transaction and recommend approval of the proposed transaction to the ETE Board. The ETE Board did not delegate to either the ETE Conflicts Committee or the ETE A&C Committee the authority to pursue alternative transactions with third parties or other strategic alternatives to the proposed transaction.

Following the ETE Board meeting, on July 24, 2018, Mr. Warren, as Chairman of the ETE Board, sent a written proposal to the ETP Board, which contemplated ETE’s acquisition of ETP in a unit-for-unit transaction, in which the ETP common units, other than those held by ETE and its subsidiaries, would each convert into the right to receive 1.194 ETE common units for each ETP common unit, representing an approximate 5.0% premium to ETP’s closing common unit price on July 23, 2018 (the “Initial ETE Offer”). The Initial ETE Offer also described ETE’s belief that the most advantageous transaction to achieve the desired objective of lowering ETP’s equity cost of capital and strengthening its balance sheet was the acquisition of ETP by ETE in an all-unit transaction, and that ETE intended to use the cash distribution savings as a result of the transaction to reduce the debt of the combined partnership and to fund capital projects.

Also on July 24, 2018, following the ETE Board meeting, the ETE Conflicts Committee held a telephonic meeting with Mr. Mason and representatives of Latham to discuss further the ETE Conflicts Committee’s role in the transaction, as well as potential legal advisors to the ETE Conflicts Committee.

Later in the day on July 24, 2018, the ETE Conflicts Committee held a telephonic meeting with representatives of Potter Anderson & Corroon LLP (“Potter Anderson”) and Latham. On the call, representatives of Potter Anderson discussed with the ETE Conflicts Committee their qualifications to serve as legal counsel to the ETE Conflicts Committee and prior engagements with the Energy Transfer family of companies. Latham then provided a brief overview of the proposed transaction, as well as timing considerations, following which the ETE Conflicts Committee dismissed the Latham representatives from the call. The ETE Conflicts Committee discussed with representatives of Potter Anderson the resolutions setting forth the ETE Conflicts Committee’s authority, and also discussed potential financial advisors that the ETE Conflicts Committee might engage for the proposed transaction. The ETE Conflicts Committee determined to engage Potter Anderson as legal counsel to the ETE Conflicts Committee. An engagement letter detailing the terms of Potter Anderson’s engagement was subsequently executed. The ETE Conflicts Committee also determined and authorized Potter Anderson to contact Citigroup Global Markets Inc. (“Citi”) in order to evaluate whether to engage Citi as the ETE Conflicts Committee’s financial advisor for the proposed transaction. After subsequent discussions among members of the ETE Conflicts Committee, representatives of Potter Anderson, and representatives of Citi, the ETE Conflicts Committee determined, based on, among other things, Citi’s reputation, experience and familiarity with ETE and ETP, to engage Citi as financial advisor to the ETE Conflicts Committee. In connection with its engagement, Citi disclosed to the ETE Conflicts Committee certain information regarding Citi’s material investment banking relationships with ETE, ETP, Sunoco and USAC during the prior two-year period.

51

Also on July 24, 2018, following receipt of the Initial ETE Offer, the ETP Board convened by teleconference with Mr. Mason, James M. Wright, General Counsel of ETP, W. Jason Healy, Associate General Counsel of ETP, and representatives of V&E to discuss the Initial ETE Offer. After review of the Initial ETE Offer and discussion with counsel, the ETP Board determined that, in light of the actual and potential conflicts of interest between ETP and the holders of ETP common units, other than ETP common units held by ETE and its affiliates, on the one hand, and ETP GP and its affiliates, on the other hand, the Initial ETE Offer and any transaction similar to the one proposed in the Initial ETE Offer should be subject to the evaluation, negotiation and approval of a committee of the ETP Board satisfying the requirements of a “Conflicts Committee” as defined in the ETP partnership agreement. After reviewing the requirements for Conflicts Committee service in the ETP partnership agreement and inquiring of Michael K. Grimm, David K. Skidmore and W. Brett Smith as to their eligibility to serve on the ETP Conflicts Committee, the ETP Board unanimously adopted resolutions creating an ETP Conflicts Committee and appointing Messrs. Grimm, Skidmore and Smith to the ETP Conflicts Committee, and delegated to the ETP Conflicts Committee the authority to (i) consider, review and evaluate any potential conflicts arising in connection with the proposed transaction and any related arrangements, (ii) consider, review, evaluate and negotiate (or delegate to any person the authority to negotiate) the terms and conditions of, and if so determined by the ETP Conflicts Committee, approve, the proposed transaction and any related arrangements, (iii) make any recommendations to the ETP Board regarding the proposed transaction and any related arrangements in light of such potential conflicts, and (iv) make any recommendations to the ETP unitholders regarding the proposed transaction and any related arrangements in light of such potential conflicts. In connection with determining that each of Messrs. Grimm, Skidmore and Smith satisfied the requirements to serve on the ETP Conflicts Committee under the ETP partnership agreement, the ETP Board discussed and considered, among other things, the fact that each of Messrs. Skidmore and Smith owned common units in ETE (as further described under “Interests of Directors and Executive Officers of ETP in the Merger—Economic Interests of ETP Managing GP Officers and Directors in ETP and ETE”) and that Mr. Smith had been a director of Sunoco from March 16, 2016 to March 6, 2018. The ETP Board did not authorize the ETP Conflicts Committee to pursue alternative transactions with third parties or other strategic alternatives to the proposed transaction.

Immediately following the ETP Board meeting, the ETP Conflicts Committee held an organizational meeting with representatives of ETP and V&E in attendance. The ETP Conflicts Committee discussed potential financial and legal advisors that could provide advice and analysis in connection with the ETP Conflicts Committee’s evaluation of the proposed transaction and their experiences with advisors in connection with certain previous transactions. Mr. Wright advised the ETP Conflicts Committee that Potter Anderson and Citi were expected to be engaged by the ETE Conflicts Committee. Following discussion and based in part on the prior experience of the ETP Conflicts Committee with Barclays and Richards Layton & Finger, P.A. (“RLF”), the ETP Conflicts Committee determined to seek to engage Barclays and RLF as its financial and legal advisors in connection with the proposed transaction, subject to reviewing information about the relationships between each of Barclays and RLF and the Energy Transfer family of companies and the negotiation of mutually acceptable engagement letters.

Following the ETP Conflicts Committee meeting on July 24, 2018, Mr. Grimm had a telephonic discussion with a representative of RLF to discuss its potential engagement as legal counsel to the ETP Conflicts Committee and with representatives of Barclays to discuss its potential engagement as financial advisor to the ETP Conflicts Committee.

Later on July 24, 2018, the ETP Conflicts Committee held an organizational meeting with representatives of ETP, V&E, Barclays and RLF in attendance. The ETP Conflicts Committee asked Barclays and RLF to provide information regarding their relationships with the Energy Transfer family of companies. The RLF representatives also explained certain responsibilities of the ETP Conflicts Committee in connection with the proposed transaction and the process for considering the proposed transaction. As further described under “The Merger—Opinion of the Financial Advisor to the ETP Conflicts Committee—General,” beginning on page 65 of this proxy statement/prospectus, on July 25, 2018, Barclays informed the ETP Conflicts Committee and RLF that as part of Barclays’ ongoing investment banking coverage efforts for ETE, Barclays employees, including certain members

52

of the Barclays team which was proposing to advise (and did advise) the ETP Conflicts Committee in the transaction, had regularly met with ETE to discuss strategic and financing alternatives potentially available to ETE, including discussions regarding a potential business combination with ETP, and provided ETE with pitch materials and analyses with respect to such a possible combination. Barclays also provided written disclosure to the ETP Conflicts Committee and RLF, which was subsequently updated on August 1, 2018, as to the nature of its relationship and engagements for ETP, ETE, and their affiliates and the amount and nature of the fees it received from such parties over the previous two years.

On July 25, 2018, representatives of V&E sent RLF an overview of a proposed structure and transaction steps for the transaction, which had been prepared by ETE and ETP management in consultation with representatives of V&E and Latham.

Also on July 25, 2018, the members of the ETP Conflicts Committee and the ETE Conflicts Committee, together with representatives of ETP, V&E, RLF, Barclays, ETE, Latham, Potter Anderson, and Citi, attended a meeting at which Mr. Long, Dylan Bramhall, Senior Vice President-Finance and Treasurer of ETP, and Mr. Mason reviewed with the group ETE’s and ETP’s business and operations, including a review of each of ETP’s and ETE’s business segments and future expected growth projects. The representatives of ETP and ETE also reviewed financial projections for the respective companies and addressed questions from the ETP Conflicts Committee, ETE Conflicts Committee and their respective advisors.

On July 26, 2018, Latham provided a draft merger agreement to Potter Anderson for review on behalf of the ETE Conflicts Committee. On July 27, 2018, Latham provided a draft merger agreement to V&E that reflected Potter Anderson’s input. The draft merger agreement did not address the economic terms of the proposed merger.

On July 28, 2018, the ETE Conflicts Committee held a telephonic meeting with representatives of Potter Anderson and Citi. At the ETE Conflicts Committee’s request, Citi provided an overview of, among other things, general trends in the midstream oil and gas industry, certain investor perspectives with respect to master limited partnerships, simplification transactions undertaken by certain midstream companies and the rationale for and market reactions to such transactions.

On July 29, 2018, the ETP Conflicts Committee held a meeting with representatives of ETP, V&E and RLF. The ETP Conflicts Committee reviewed information provided by Barclays regarding its relationships with ETE, ETP and the other members of the Energy Transfer family of companies, which information is more fully described under “Opinion of the Financial Advisor to the ETP Conflicts Committee—General.” The ETP Conflicts Committee had discussions regarding such relationships, as well as Barclays’ experience and qualifications. ETP management’s expressed confidence in Barclays, Barclays’ familiarity with the Energy Transfer family of companies and the fees requested by Barclays. After considering all the factors and circumstances—including Barclays’ relationships with the Energy Transfer family of companies and Barclays’ experience and qualifications to provide high-quality financial advice to the ETP Conflicts Committee in connection with its consideration of the proposed transaction—the ETP Conflicts Committee determined to engage Barclays as its financial advisor. An engagement letter detailing the terms of Barclays’ engagement was subsequently executed. The ETP Conflicts Committee also reviewed information provided by RLF regarding its relationships with the Energy Transfer family of companies and had discussions regarding the experience and qualifications of RLF and its familiarity with the Energy Transfer family of companies. The ETP Conflicts Committee determined that RLF had the requisite experience and qualifications to provide high-quality legal advice to the ETP Conflicts Committee in connection with its consideration of the proposed transaction and determined to engage RLF as its legal advisor. An engagement letter detailing the terms of RLF’s engagement was subsequently executed.

Later on July 29, 2018, the ETP Conflicts Committee held a meeting with representatives of Barclays and RLF. Barclays made a presentation to the ETP Conflicts Committee regarding, among other things, (i) the recent performance of ETE and ETP, (ii) certain potential alternatives for ETP to the proposed transaction, and

53

(iii) Barclays’ preliminary financial analysis of the proposed transaction. The potential alternatives to the proposed transaction presented to the ETP Conflicts Committee included (i) ETP maintaining the status quo, (ii) ETP acquiring the outstanding equity of ETE or the incentive distribution rights in ETP held by ETE, or (iii) ETP decreasing the distribution on its common units. The ETP Conflicts Committee and its advisors also discussed the rationale for the proposed transaction from the perspective of ETP and the unaffiliated ETP common unitholders, the financial projections provided by management and the growth projects included in management’s financial projections.

On July 30, 2018, the ETE Conflicts Committee held a meeting with representatives of Potter Anderson and Citi. Among other things discussed during the meeting were potential benefits of and certain considerations regarding certain alternatives to the proposed transaction, including ETP acquiring ETE, ETP acquiring the incentive distribution rights in ETP held by ETE, and a resetting of the incentive distribution rights in exchange for common units of ETP. Citi also discussed certain financial matters relating to ETP and ETE and preliminary financial perspectives regarding the proposed transaction. Also during the meeting, Potter Anderson reviewed with the ETE Conflicts Committee their duties and obligations in connection with the proposed transaction.

On July 30, 2018, the ETP Conflicts Committee held a series of meetings with representatives of Barclays and RLF to discuss the proposed transaction. The ETP Conflicts Committee also invited representatives of ETE and ETP and representatives of V&E to attend portions of its meetings to solicit their views on, among other things, (i) the financial projections provided by management and potential upside or downside scenarios thereto, (ii) potential alternatives for ETP to the proposed transaction, and (iii) potential investor and rating agency reactions to the proposed transaction. In executive session with representatives of Barclays and RLF in attendance, the ETP Conflicts Committee engaged in further consideration of Barclays’ preliminary financial analysis of the proposed transaction and the alternatives for ETP to the proposed transaction, as well as the potential reaction of the unaffiliated ETP common unitholders to the proposed transaction. Following consideration, the ETP Conflicts Committee concluded that it would make a counteroffer to ETE in which ETE would acquire the ETP common units not already held by ETE and its subsidiaries in a unit-for-unit exchange at an exchange ratio of 1.42 ETE common units for each ETP common unit, representing an approximate 24.8% premium based on closing prices for ETP common units and ETE common units on July 23, 2018, and the proposed transaction would be conditioned on obtaining the approval of holders of at least a majority of the outstanding ETP common units held by unaffiliated ETP common unitholders (the “ETP Counter”). The ETP Conflicts Committee then delivered a letter to the ETE Conflicts Committee detailing the ETP Counter.

Following the receipt of the ETP Counter on July 30, 2018, the ETE Conflicts Committee held a series of meetings with representatives of Potter Anderson and Citi to discuss the ETP Counter. Among other things, the ETE Conflicts Committee discussed with its advisors the proposed exchange ratio and other aspects of the ETP Counter, including the request that the proposed transaction would be conditioned on obtaining the approval of holders of at least a majority of the outstanding ETP common units held by unaffiliated ETP common unitholders. In addition, the ETE Conflicts Committee reviewed certain updated information previously provided by Citi to the ETE Conflicts Committee regarding Citi’s material investment banking relationships with ETE, ETP, Sunoco and USAC during the prior two-year period. Following discussion and consideration, the ETE Conflicts Committee determined to make a counter proposal for ETE to acquire ETP in a unit-for-unit exchange at an exchange ratio of 1.222 ETE common units for each ETP common unit, representing an approximate 7.3% premium based on the closing prices for the common units of each of ETP and ETE on July 23, 2018, and also accepting the ETP Conflicts Committee’s request that the transaction be conditioned on obtaining the approval of holders of at least a majority of the outstanding ETP common units held by unaffiliated ETP common unitholders (the “Second ETE Offer”). Later in the day on July 30, 2018, the ETE Conflicts Committee delivered a letter to the ETP Conflicts Committee detailing the Second ETE Offer.

Also throughout the day on July 30, 2018, senior management of ETP and ETE discussed proposed transaction details and due diligence matters with representatives of the ETP Conflicts Committee’s and the ETE Conflicts Committee’s respective legal and financial advisors. In addition, representatives of V&E and RLF met

54

in person to discuss issues identified in the initial draft of the merger agreement and related matters. Representatives of V&E also had preliminary discussions with representatives of Latham regarding provisions in the merger agreement, including (i) the restrictions on ETP’s and ETE’s ability to engage in certain activities after the execution of the merger agreement and prior to closing, (ii) the representations and warranties given by ETP and ETE, particularly in light of the overlapping management and knowledge of the two entities, (iii) the inclusion of each of the general partners of ETP and ETE as parties to the merger agreement, and (iv) the remedies and termination provisions.

Following receipt of the Second ETE Offer, in the evening of July 30, 2018, the ETP Conflicts Committee held a meeting with representatives of Barclays and RLF to discuss the proposed transaction and the Second ETE Offer made by the ETE Conflicts Committee. Following consideration of the Second ETE Offer and Barclays’ preliminary financial analysis of the proposed transaction and the Second ETE Offer, the ETP Conflicts Committee concluded that it would make a counteroffer to ETE in which ETE would acquire the ETP common units not already held by ETE and its subsidiaries in a unit-for-unit exchange at an exchange ratio of 1.4 ETE common units for each ETP common unit, representing an approximate 23.1% premium based on closing prices for ETP common units and ETE common units on July 23, 2018 (the “Second ETP Counter”). The ETP Conflicts Committee noted that an agreement had been reached that the proposed transaction would be conditioned on obtaining the approval of holders of at least a majority of the outstanding ETP common units held by unaffiliated ETP common unitholders.

On the morning of July 31, 2018, RLF delivered a letter containing the Second ETP Counter to the ETE Conflicts Committee as instructed by the ETP Conflicts Committee. Thereafter, the ETP Conflicts Committee held a series of meetings with representatives of Barclays and RLF to discuss the proposed transaction. The ETP Conflicts Committee received a presentation from RLF regarding the duties and obligations of the ETP Conflicts Committee in connection with the proposed transaction. In addition, the ETP Conflicts Committee invited representatives of V&E to attend a portion of its meetings to participate in discussions regarding the terms of the proposed merger agreement and certain changes to the proposed merger agreement prepared by V&E and RLF. Following discussion, the ETP Conflicts Committee authorized V&E and RLF to send a revised version of the merger agreement to Latham, Potter Anderson, and ETE. The draft merger agreement included the requirement that holders of at least a majority of the outstanding ETP common units held by unaffiliated ETP common unitholders must vote to approve the transaction.

Also on the morning of July 31, 2018, the ETE Board held a meeting with senior management and representatives of Latham present. During the meeting, Messrs. Long and Mason provided the ETE Board with an update on the transaction, while Mr. Brannon provided an update on the negotiations described above between the ETE Conflicts Committee and the ETP Conflicts Committee. Mr. Mason and a representative from Latham also led the ETE Board through a discussion regarding the dilution to the equity ownership of ETE GP and its affiliates as a result of the proposed transaction with ETP, and provided the ETE Board with an overview of ETE’s and ETP’s financial performance under the direct and indirect control of ETE GP, the increased activism in the energy industry and the control provisions in the existing ETE partnership agreement. Mr. Mason also discussed the contractual preemptive right of ETE GP set forth in the ETE partnership agreement that provides ETE GP the right to acquire, in connection with any issuance of common units by ETE, additional ETE common units to allow ETE GP to maintain the percentage interest of ETE GP and its affiliates of ETE’s outstanding common units prior to any such transaction. After such discussion, Mr. Warren proposed to the ETE Board that, as part of the proposed transaction, ETE issue a new security, the ETE Class A Units, to ETE GP that would, among other things, enable ETE GP and its affiliates to retain their current voting percentage interests in ETE following the consummation of the proposed merger and require a separate class vote of the ETE Class A Units in order to remove ETE’s general partner. Mr. Warren, the owner of a controlling interest in ETE GP, stated that he would not be inclined to support the proposed transaction without the issuance of the ETE Class A Units. Mr. Mason provided additional detail regarding the ETE Class A Units, and after a discussion with the ETE Board, the ETE Board authorized Mr. Mason to inform the ETE Conflicts Committee and the ETP Conflicts Committee of the proposal to issue ETE Class A Units to ETE GP and the terms of such units.

55

Also on the morning of July 31, 2018, Mr. Mason and representatives of Latham provided to the ETE Conflicts Committee, the ETP Conflicts Committee and their respective legal advisors a written proposal regarding the issuance of ETE Class A Units to ETE GP. As set forth in the proposal, the ETE Class A Units would be entitled to a voting interest (the “Class A Unit voting interest”) that together with the voting interest held by ETE GP and its affiliates immediately following the proposed merger is equal to the voting interest of ETE GP and its affiliates prior to the proposed merger. The proposed terms of the ETE Class A Units provided that the Class A units would generally vote together with the ETE common units as a single class but would also be entitled to a separate class vote on any vote to remove ETE GP as the general partner. The proposal also specified that, upon the issuance by ETE of any common units or other securities with voting rights pari passu with the common units, ETE would be required to issue additional ETE Class A Units to the Class A unitholders such that the ETE Class A Units would retain the Class A Unit voting interest. Mr. Mason also explained that the ETE Class A Units would generally not be transferable by the holder(s) without the consent of the ETE Conflicts Committee unless a transfer was to an affiliate of such holder(s).

Subsequent to the ETE Board meeting on July 31, 2018, the ETE Conflicts Committee met with representatives of Potter Anderson and Citi to discuss the Second ETP Counter. The ETE Conflicts Committee and its advisors discussed, among other things, the proposed exchange ratio of 1.400 ETE common units for each ETP common unit not already held by ETE and its subsidiaries. After discussion and consideration, the ETE Conflicts Committee determined to make a counter proposal for ETE to acquire ETP in a unit-for-unit exchange at an exchange ratio of 1.234 ETE common units for each ETP common unit not already held by ETE and its subsidiaries, representing an approximate 8.5% premium based on the closing prices for ETP common units and ETE common units on July 23, 2018 (the “Third ETE Offer”). The ETE Conflicts Committee also discussed with representatives of Potter Anderson and Citi the proposal regarding the issuance of ETE Class A Units to ETE GP. Subsequently, the ETE Conflicts Committee delivered a letter to the ETP Conflicts Committee detailing the Third ETE Offer. After the ETE Conflicts Committee meeting, the ETE Conflicts Committee, together with its advisors, met with Mr. Mason and representatives of Latham to discuss the proposed new ETE Class A Units.

Also on the morning of July 31, 2018, following receipt of the Third ETE Offer, the ETP Conflicts Committee held a meeting with representatives of Barclays and RLF to discuss the proposed transaction and the Third ETE Offer made by the ETE Conflicts Committee. The ETP Conflicts Committee considered the terms of the Third ETE Offer and financial and legal analysis provided by its advisors. The ETP Conflicts Committee discussed, among other things, the effect of the proposed transaction on the amount of distributions that unaffiliated ETP common unitholders could expect to receive on a quarterly basis, the potential benefits and impact of an exchange ratio that provided unaffiliated ETP common unitholders with more ETE common units and the condition that the transaction be approved by the holders of at least a majority of the outstanding ETP common units held by unaffiliated ETP common unitholders. Following discussion, the ETP Conflicts Committee determined that it would request a meeting with the ETE Conflicts Committee to explain its perspectives on the proposed transaction and to make a counteroffer to ETE in which ETE would acquire the ETP common units not already held by ETE and its subsidiaries in a unit-for-unit exchange at an exchange ratio of 1.3 ETE common units for each ETP common unit, representing an approximate 14.3% premium based on the closing prices for the common units of each of ETP and ETE on July 23, 2018 (the “Third ETP Counter”).

Later in the morning of July 31, 2018, Mr. Mason and representatives of Latham held a meeting with the ETE Conflicts Committee, the ETP Conflicts Committee and the conflicts committees’ respective legal and financial advisors to discuss the proposed ETE Class A Units. Mr. Mason addressed a number of questions from the ETP Conflicts Committee and representatives of RLF, V&E and Potter Anderson.

Later on July 31, 2018, following Mr. Mason’s review of the proposed ETE Class A Units, the ETP Conflicts Committee held a meeting with representatives of Barclays and RLF. The ETP Conflicts Committee considered the potential impact of the ETE Class A Units on the proposed transaction and the consideration to be received by the unaffiliated ETP common unitholders as part of the proposed transaction. Following consideration, the ETP Conflicts Committee determined to propose that the terms of the ETE Class A Units be

56

modified to eliminate the class vote on removal of ETE’s general partner and to modify the terms such that ETE GP and its affiliates would maintain the same relative voting interest in ETE (through the ownership of ETE Class A Units and its continued ownership of ETE common units) that ETE GP and its affiliates had prior to the proposed transaction but that, after the proposed transaction, the ETE Class A Units would only continue to maintain their relative voting interest until such time as Mr. Warren ceased to be involved in the management of ETE GP. The ETP Conflicts Committee authorized the RLF representatives to deliver such feedback to ETE and its advisors.

Later on July 31, 2018, the ETE Conflicts Committee and the ETP Conflicts Committee met to negotiate the exchange ratio for the proposed transaction. At this meeting, the ETP Conflicts Committee delivered and explained its rationale for, the Third ETP Counter to the ETE Conflicts Committee. In response, the ETE Conflicts Committee proposed an exchange ratio of 1.25 ETE common units for each ETP common unit.

Later on July 31, 2018, the ETE Conflicts Committee met with representatives of Potter Anderson and Citi to discuss the negotiation of the exchange ratio and the proposed ETE Class A Units. Following discussion and consideration, the ETE Conflicts Committee determined that it would be appropriate for the terms of the proposed transaction to provide for the issuance of ETE Class A Units to ETE GP in order for ETE GP and its affiliates to maintain their relative voting position in connection with the proposed transaction; however, the ETE Conflicts Committee determined that the terms of the ETE Class A Units should not provide for a separate class vote on removal of the general partner and should not maintain the relative ETE Class A Unit voting interest in perpetuity. The ETE Conflicts Committee also determined that, without approval of the ETE Conflicts Committee, the transferability of the ETE Class A Units should be limited to transfers solely for estate planning purposes. The ETE Conflicts Committee directed Potter Anderson to meet with RLF, as counsel to the ETP Conflicts Committee, to discuss each side’s reaction to the requested terms of the ETE Class A Units.

Later on July 31, 2018, V&E provided comments to the merger agreement, which reflected the ETP Conflicts Committee’s input, to Latham and the ETE Conflicts Committee. V&E’s comments to the merger agreement included a requirement that the proposed transaction be subject to the approval of holders of at least a majority of the outstanding ETP common units held by unaffiliated ETP common unitholders, in addition to the requirement under the ETP partnership agreement that the transaction be approved by holders of a majority of the ETP common units. Additionally, the revised draft from V&E contemplated a termination fee equal to 2% of the equity value of the transaction and a $30 million expense reimbursement cap.

Later in the afternoon on July 31, 2018, representatives of Potter Anderson and RLF met, on behalf of the ETE Conflicts Committee and the ETP Conflicts Committee, respectively, to discuss the requested terms of the ETE Class A Units.

Later on July 31, 2018, the members of the ETE Conflicts Committee and the ETP Conflicts Committee met with Mr. Warren, acting on behalf of ETE GP as the ETE general partner, and Messrs. Long and Mason to discuss the exchange ratio for the proposed transaction. At such meeting, the ETP Conflicts Committee continued to propose a 1.3 exchange ratio for the proposed transaction and the ETE Conflicts Committee expressed support for an exchange ratio of 1.27 ETE common units for each ETP common unit.

Subsequently, the ETE Conflicts Committee met with representatives of Potter Anderson to report on the meeting with the members of the ETP Conflicts Committee and Mr. Warren and to discuss the ETE Conflicts Committee’s response to the proposed ETE Class A Units, and directed Potter Anderson to provide the ETE Conflicts Committee’s feedback to Mr. Mason.

Following the ETE Conflicts Committee meeting, representatives of Potter Anderson and RLF relayed to Mr. Mason and Latham feedback from the ETE Conflicts Committee and the ETP Conflicts Committee with respect to the terms of the proposed ETE Class A Units. In particular, legal counsel noted that the conflicts committees were opposed to the separate class vote of the ETE Class A Units with respect to any vote on the

57

removal of ETE GP as the general partner. In addition, legal counsel relayed that the conflicts committees were opposed to allowing the ETE Class A Units to retain the ETE Class A Unit voting interest in perpetuity. Instead, the conflicts committees proposed that the holder(s)’ right to receive additional ETE Class A Units upon the issuance by ETE of common units or other securities with voting rights pari passu to the common units should terminate at the time that Mr. Warren ceased to be involved in the management of ETE GP. Further, the conflicts committees proposed that ETE GP waive its preemptive right in connection with the issuance of ETE common units in the merger and that only transfers by the holder(s) for estate planning purposes be permitted without ETE Conflicts Committee’s approval.

Later on July 31, 2018, the ETP Conflicts Committee held a meeting with representatives of Barclays and RLF. The ETP Conflicts Committee updated its advisors regarding its meetings with the ETE Conflicts Committee and representatives of ETE. The ETP Conflicts Committee and its advisors further considered the proposed transaction, including the preliminary financial analysis prepared by Barclays and the rationale for the proposed transaction. The ETP Conflicts Committee discussed the potential for an acceptable exchange ratio of less than 1.3 ETE common units for each ETP common unit. The RLF representatives also reported on their discussions with Mr. Mason, and representatives of Latham and Potter Anderson regarding the ETE Class A Units.

Later in the day on July 31, 2018, Latham sent a revised draft of the merger agreement to V&E. The draft provided by Latham reflected the requirement that the transaction be approved by holders of at least a majority of the outstanding ETP common units held by unaffiliated ETP common unitholders, as well as the $30 million expense reimbursement cap. However, ETE proposed a termination fee equal to 4% of the equity value of the transaction.

Later in the day on July 31, 2018, Mr. Mason reported to representatives of Potter Anderson and RLF that Messrs. Warren and Davis (in their capacities as sole members of ETE GP) were agreeable to a waiver of ETE GP’s preemptive right in connection with the merger and also agreeable to the proposed revisions to the terms of the ETE Class A Units, provided that the right to receive additional ETE Class A Units upon the issuance by ETE of common units or other securities with voting rights pari passu to the common units would only terminate if Mr. Warren ceased to be an officer or director of ETE GP.

Later in the day on July 31, 2018, Latham sent a draft of the ETE LPA amendment, which included the proposed terms of the ETE Class A Units, to V&E, Potter Anderson and RLF. The draft reflected the discussions regarding the ETE Class A Units had among the ETE Conflicts Committee, the ETP Conflicts Committee, ETE and representatives of Latham earlier in the day.

On the morning of August 1, 2018, the ETE Board held a meeting with management and representatives of Latham and Potter Anderson in attendance. All members of the ETE Board were present. At the meeting, management updated the ETE Board as to the status of negotiations, including with respect to the ETE Class A Units. Mr. Brannon also provided an update to the ETE Board on the status of negotiations relating to the exchange ratio. Representatives of Latham summarized the terms of the draft merger agreement for the ETE Board.

Following the ETE Board meeting, the ETE Conflicts Committee met with representatives of Potter Anderson and Citi to discuss the status of the transaction documents, the proposed terms of the ETE Class A Units, and the anticipated negotiations with the ETP Conflicts Committee with respect to the exchange ratio. The ETE A&C Committee subsequently held a meeting, together with representatives of Potter Anderson, to discuss the proposed transaction.

Later in the morning of August 1, 2018, the ETE Conflicts Committee and the ETP Conflicts Committee met to negotiate the final exchange ratio for the proposed transaction, and, at the conclusion of such negotiations,

58

the ETE Conflicts Committee and the ETP Conflicts Committee agreed to an exchange ratio of 1.28 ETE common units for each ETP common unit, subject to resolution of the final terms included in the definitive documents.

On August 1, 2018, V&E provided comments to the merger agreement to Latham. The comments reflected a termination fee equal to 3% of the equity value of the transaction. Later in the day, Latham provided a revised draft of the merger agreement, which reflected a 3% termination fee as proposed by V&E. Also throughout the day on August 1, 2018, revised drafts of the merger agreement and the ETE LPA amendment, and a draft waiver of preemptive rights by ETE GP, were exchanged among Latham, V&E, RLF and Potter Anderson.

Later in the morning of August 1, 2018, the ETP Board held a meeting at which representatives of V&E and ETP management were present. During the meeting, the ETP Conflicts Committee provided an update to the ETP Board as to its process to date, including that the ETP Conflicts Committee and ETE Conflicts Committees agreed to an exchange ratio of 1.28 ETE common units for each ETP common unit, subject to resolution of the final terms included in the definitive documents. Representatives of V&E summarized the terms of the merger agreement, including the closing conditions, the representations and warranties, the operating covenants, the deal protections (including the no-shop provisions and related exceptions, the ETP Board’s ability to change its recommendation and to negotiate alternative proposals, termination events, termination fees, and expense reimbursement), the amendment and waiver provisions, and governing law.

During the early afternoon of August 1, 2018, the ETE Conflicts Committee held a meeting with its legal and financial advisors to discuss the proposed transaction. At this meeting, among other matters, Potter Anderson updated the ETE Conflicts Committee regarding the terms of the merger agreement, including the issuance of the ETE Class A Units, the ETE LPA amendment, and the waiver by ETE GP of its preemptive rights in connection with ETE’s issuance of common units in the proposed transaction. Also during this meeting, Citi discussed with the ETE Conflicts Committee certain financial perspectives regarding the exchange ratio of 1.28 ETE common units for each ETP common unit agreed upon by the ETE Conflicts Committee and the ETP Conflicts Committee. Following a discussion and consideration of the proposed transaction, the ETE Conflicts Committee unanimously in good faith (i) determined that the proposed transaction, including the ETE Class A Unit issuance, on the terms and conditions set forth in the merger agreement and the ETE LPA amendment, were advisable, fair and reasonable to ETE and in the best interests of ETE and its unaffiliated unitholders, (ii) approved the merger agreement, the ETE LPA amendment and the proposed transaction, including the ETE Class A Unit issuance (with such approval constituting “Special Approval” for all purposes under the ETE partnership agreement), and (iii) recommended that the ETE Board approve the merger agreement, the ETE LPA amendment, and the proposed transactions, including the ETE Class A Unit issuance.

Following the ETE Conflicts Committee meeting, on August 1, 2018, the ETE A&C Committee held a meeting, together with representatives of Potter Anderson and Citi, to discuss the proposed transaction. At this meeting, among other matters, Mr. Brannon and Mr. Anderson provided an update as to the process engaged in by the ETE Conflicts Committee, including the negotiation of the exchange ratio, and the ETE Conflicts Committee’s earlier determination and approval of the proposed transaction, Potter Anderson updated the ETE A&C Committee regarding the terms of the merger agreement, including the issuance of the ETE Class A Units and the ETE LPA amendment, and, as requested by the ETE Conflicts Committee, Citi discussed with the ETE A&C Committee certain financial perspectives as previously discussed with the ETE Conflicts Committee regarding the exchange ratio of 1.28. Following a discussion regarding the proposed transaction, the merger agreement, the Class A Unit issuance and related matters, the ETE A&C Committee approved, and resolved to recommend that the ETE Board approve, the merger agreement and the ETE LPA amendment, and the transactions contemplated thereby, including the merger and the Class A Unit issuance (with such approval constituting “Special Approval” for all purposes under the ETE GP limited liability company agreement).

Following the ETE Conflicts Committee and ETE A&C Committee meetings, on August 1, 2018, the ETE Board held a board meeting, which ETE management and representatives of Latham attended. All members of

59

the ETE Board were present. Mr. Brannon provided the ETE Board an update on the 1.28 exchange ratio, as well as the process undertaken by the ETE Conflicts Committee. Following that discussion, Mr. Brannon, on behalf of the ETE Conflicts Committee and the ETE A&C Committee, then advised the ETE Board that both committees had approved the merger agreement and related transactions, including the issuance of the ETE Class A Units, and recommended that the ETE Board approve the merger agreement and related transactions. The ETE Board then discussed various legal, financial and other considerations relating to the proposed transaction, including factors that supported approving the proposed transaction and factors that did not support approving the proposed transaction, and following such discussion, the ETE Board determined that it was in the best interests of ETE and its partners, and declared it advisable, for ETE GP and ETE to enter into the merger agreement, and the ETE Board approved and adopted the merger agreement and the transactions contemplated thereby, including the merger and the issuance of the new ETE Class A Units.

Also during the early afternoon of August 1, 2018, the ETP Conflicts Committee held a meeting with representatives of Barclays and RLF. Prior to the meeting, substantially final versions of the merger agreement, the ETE LPA amendment, the ETP LPA amendment and other ancillary documents were distributed to the ETP Conflicts Committee. The ETP Conflicts Committee reviewed the rationale for the merger (which rationale included the reasons set forth under “—Recommendation of the ETP Board; Reasons for the Merger”). The RLF representatives provided the ETP Conflicts Committee with an overview of various matters relating to the proposed transaction, including updates to the definitive documents. Representatives of Barclays reviewed Barclays’ financial analysis of the proposed transaction with the ETP Conflicts Committee. Upon the request of the ETP Conflicts Committee, Barclays delivered an oral opinion as of August 1, 2018, which was subsequently confirmed by delivery of a written opinion dated as of such date, to the effect that the exchange ratio to be offered to the unaffiliated ETP common unitholders was fair, from a financial point of view, to the unaffiliated ETP common unitholders. Following such discussion and receipt of the Barclays opinion, the ETP Conflicts Committee unanimously (i) determined in good faith that the proposed transaction, including the merger agreement and the transactions contemplated thereby, on the terms and conditions set forth in the merger agreement and the ETP LPA amendment, are advisable and fair and reasonable to ETP, and in the best interests of ETP and the unaffiliated ETP common unitholders, (ii) approved the proposed transaction (including the merger agreement and the ETP LPA amendment), upon the terms and conditions set forth in the merger agreement and the ETP LPA amendment, with such approval constituting “Special Approval” for all purposes under the ETP partnership agreement, and (iii) resolved to recommend that the ETP Board approve the proposed transaction upon the terms set forth in the merger agreement and the ETP LPA amendment and submit the merger agreement to the holders of ETP common units for approval and recommend the approval of the merger agreement by the holders of ETP common units.

Later on the afternoon of August 1, 2018, following the ETE Board meeting and the ETP Conflicts Committee meeting, the ETP Board held a meeting at which representatives from ETP management and V&E also participated. Prior to the meeting, substantially final versions of the merger agreement, ETE LPA amendment, the ETP LPA amendment and other ancillary documents were distributed to the ETP Board, and during the meeting representatives of V&E summarized the key changes to the terms of the merger agreement since the morning meeting of the ETP Board. The ETP Conflicts Committee then reviewed with the ETP Board its process in evaluating, negotiating and recommending the merger to the ETP Board, and its rationale therefore (which rationale included the reasons set forth under “—Recommendation of the ETP Board; Reasons for the Merger”). Mr. Grimm further advised the ETP Board that the ETP Conflicts Committee had approved the merger agreement, that such approval was intended to constitute “Special Approval” under the ETP partnership agreement, and that the ETP Conflicts Committee recommended that the ETP Board approve the merger agreement, submit the merger agreement to ETP’s limited partners for approval and recommend that ETP’s limited partners approve the merger agreement. Following this recommendation, representatives of V&E reviewed with the members of the ETP Board their obligations under the ETP partnership agreement as well as the provisions in the ETP partnership agreement that provide that ETP GP will be deemed to have acted in “good faith” and in compliance with the ETP partnership agreement so long as, among other things, either the ETP Conflicts Committee had granted “Special Approval” of the proposed transactions or the proposed transactions

60

were approved by ETP unaffiliated unitholder approval, as required by the terms of the merger agreement. After discussion of various considerations relating to the proposed transaction, the ETP Board determined that the form, terms and provisions of the merger agreement and the transactions contemplated thereby, including the merger and the ETP LPA amendment, were advisable, fair and reasonable to and in the best interests of ETP and its partners, and declared it advisable, for ETP to enter into the merger agreement, and the ETP Board approved and adopted the merger agreement and the transactions contemplated thereby, including the merger.

On August 1, 2018, the parties finalized and executed the merger agreement and issued a press release announcing the transaction.

Recommendation of the ETP Board; Reasons for the Merger

The ETP Conflicts Committee consists of three directors: Michael K. Grimm, David K. Skidmore and W. Brett Smith. Each of Messrs. Grimm, Skidmore and Smith satisfy the requirements to serve on the “Conflicts Committee” as such term is defined in the ETP partnership agreement. According to the ETP partnership agreement the “Conflicts Committee” must consist of a committee of the ETP Board composed entirely of two or more directors who are not (a) security holders, officers or employees of ETP GP, (b) officers, directors (other than members of the ETP Board) or employees of any affiliate of ETP GP or (c) holders of any ownership interest in the partnership group (as defined in the ETP partnership agreement), consisting of ETP, Sunoco Logistics Partners Operations L.P. and any subsidiary of any such entity, other than ETP common units. The directors serving on the ETP Conflicts Committee must also meet the independence standards required of directors who serve on an audit committee of a board of directors established by the Exchange Act and the rules and regulations of the SEC promulgated thereunder and by the NYSE.

The ETP Board authorized the ETP Conflicts Committee to (i) consider, review and evaluate any potential conflicts arising in connection with the merger and any other arrangements or agreements related to the proposed merger (“related arrangements”); (ii) consider, review, evaluate and negotiate (or delegate to any person the authority to negotiate) the terms and conditions of, and if so determined by the ETP Conflicts Committee, approve, the proposed merger and any related arrangements; (iii) make any recommendations to the ETP Board regarding the proposed merger and any related arrangements in light of such potential conflicts and (iv) make any recommendations to the holders of ETP common units regarding the proposed merger and any related arrangements in light of such potential conflicts.

The ETP Conflicts Committee retained, and was advised by, Richards, Layton & Finger, P.A. (“RLF”) as its outside legal counsel and Barclays as its financial advisor. The ETP Conflicts Committee oversaw the performance of financial and legal due diligence by its advisors, conducted a review and evaluation of ETE’s proposal, considered other alternatives to the merger, including maintaining the status quo, and conducted, with the assistance of its advisors, negotiations with ETE and its representatives with respect to ETE’s proposal, the merger agreement and other related arrangements. ETP retained Vinson & Elkins L.L.P. as its outside legal counsel.

The ETP Conflicts Committee, by unanimous vote at a meeting held on August 1, 2018, (i) determined in good faith that the proposed merger, including the merger agreement and the ETP LPA amendment and the transactions contemplated thereby, on the terms and conditions set forth in the merger agreement and the ETP LPA amendment are advisable and fair and reasonable to ETP, and in the best interests of ETP and the unaffiliated ETP common unitholders; (ii) approved the proposed merger (including the merger agreement and the ETP LPA amendment), upon the terms and conditions set forth in the merger agreement and the ETP LPA amendment, with such approval constituting “Special Approval” (as defined in the ETP partnership agreement) for all purposes under the ETP partnership agreement; and (iii) resolved to recommend that the ETP Board: (A) approve the proposed merger (including the merger agreement and the ETP LPA amendment and the transactions contemplated thereby) and (B) submit the merger agreement to the holders of common units of ETP for approval and recommend adoption of the merger agreement by the holders of ETP common units.

61

Based on the ETP Conflicts Committee’s recommendation, the ETP Board, by unanimous vote at a meeting held on August 1, 2018, (i) determined that the form, terms and provisions of the merger agreement and the transactions contemplated thereby, including the merger and the ETP LPA amendment, are advisable, fair and reasonable to and in the best interests of ETP and ETP’s limited partners, (ii) approved and adopted the merger agreement and approved the execution, delivery and performance of the merger agreement and the consummation of the transactions contemplated thereby, including the merger, in all respects, (iii) authorized and empowered ETP Managing GP and ETP to enter into the merger agreement and to consummate the transactions contemplated thereby, including the merger, on the terms and subject to the conditions set forth in the merger agreement and (iv) resolved to recommend to the holders of ETP common units that such holders vote in favor of the adoption of the merger agreement.

The ETP Conflicts Committee and the ETP Board viewed the following factors as being generally positive or favorable in coming to their determinations and recommendation with respect to the merger:

62

63

The ETP Conflicts Committee and the ETP Board considered the following additional factors in making their determinations and recommendation with respect to the merger:

64

The foregoing discussion is not intended to be exhaustive, but is intended to address the material information and principal factors considered by the ETP Conflicts Committee and the ETP Board in considering the merger. In view of the number and variety of factors and the amount of information considered, the ETP Conflicts Committee and the ETP Board did not find it practicable to, and did not make specific assessments of, quantify or otherwise assign relative weights to, the specific factors considered in reaching their determinations. In addition, the ETP Conflicts Committee and the ETP Board did not undertake to make any specific determination as to whether any particular factor, or any aspect of any particular factor, was favorable or unfavorable to their ultimate determinations, and individual members of the ETP Conflicts Committee and the ETP Board may have given different weights to different factors. The ETP Conflicts Committee and the ETP Board made their recommendations based on the totality of information presented to, and the investigation conducted by, the ETP Conflicts Committee and the ETP Board. It should be noted that certain statements and other information presented in this section are forward-looking in nature and, therefore, should be read in light of the factors discussed under the heading “Cautionary Statement Regarding Forward-Looking Statements.”

The ETP Board, based on the recommendation of the ETP Conflicts Committee, recommends that ETP common unitholders vote “FOR” the adoption of the merger agreement and the transactions contemplated thereby and “FOR” the proposal to approve the adjournment of the special meeting, if necessary, to solicit additional proxies if there are not sufficient votes to approve the merger agreement at the time of the special meeting.

Opinion of the Financial Advisor to the ETP Conflicts Committee

The ETP Conflicts Committee engaged Barclays to act as the ETP Conflicts Committee’s financial advisor with respect to the proposed transaction. On August 1, 2018, Barclays rendered its oral opinion (which was subsequently confirmed in writing) to the ETP Conflicts Committee that, as of such date and based upon and subject to the qualifications, limitations and assumptions stated in its opinion, the exchange ratio to be offered to the unaffiliated ETP common unitholders in the proposed transaction is fair, from a financial point of view, to such unaffiliated ETP common unitholders.

The full text of Barclays’ written opinion, dated as of August 1, 2018, is attached to this proxy statement/prospectus as Annex B. Barclays’ written opinion sets forth, among other things, the assumptions made, procedures followed, factors considered and limitations upon the review undertaken by Barclays in rendering its opinion. You are encouraged to read the opinion carefully in its entirety. The following is a summary of Barclays’ opinion and the methodology that Barclays used to render its opinion. This summary is qualified in its entirety by reference to the full text of the opinion.

Barclays’ opinion, the issuance of which was approved by Barclays’ Valuation and Fairness Opinion Committee, is addressed to the ETP Conflicts Committee, addresses only the fairness to unaffiliated ETP

65

common unitholders, from a financial point of view, of the exchange ratio to be offered to such unaffiliated ETP common unitholders in the proposed transaction and does not constitute a recommendation to any unaffiliated ETP common unitholder as to how such unaffiliated ETP common unitholder should vote or act with respect to the proposed transaction or any other matter. The terms of the proposed transaction were determined through arm’s-length negotiations between the ETP Conflicts Committee and the ETE Conflicts Committee and were approved unanimously by the ETP Conflicts Committee. Barclays did not recommend that any specific form of consideration should be offered to unaffiliated ETP common unitholders or that any specific form of consideration constituted the only appropriate consideration for the proposed transaction. Barclays was not requested to address, and its opinion does not in any manner address, the underlying business decision to proceed with or effect the proposed transaction or the likelihood of consummation of the proposed transaction or the relative merits of the proposed transaction as compared to any other transaction or business strategy in which ETP might engage. In addition, Barclays expressed no view as to, and its opinion does not in any manner address, the fairness of the amount or the nature of any compensation to any officers, directors or employees of any parties to the proposed transaction, or any class of such persons, relative to the exchange ratio to be offered to the unaffiliated ETP common unitholders in the proposed transaction or otherwise. In addition, Barclays assumed that the issuance of the ETE Class A Units will be effected, but expressed no view as to the fairness, from a financial point of view, as to such issuance. No limitations were imposed by ETP or the ETP Conflicts Committee upon Barclays with respect to the investigations made or procedures followed by it in rendering its opinion.

In arriving at its opinion, Barclays reviewed and analyzed, among other things:

66

In addition, Barclays has had discussions with the management of ETP and ETE concerning their respective businesses, operations, assets, liabilities, financial condition and prospects and have undertaken such other studies, analyses and investigations as Barclays deemed appropriate.

In arriving at its opinion, Barclays assumed and relied upon the accuracy and completeness of the financial and other information used by Barclays without any independent verification of such information (and had not assumed responsibility or liability for any independent verification of such information) and further relied upon the assurances of the management of ETP that they are not aware of any facts or circumstances that would make such information inaccurate or misleading. With respect to the ETP Unaudited Financial Projections, upon the advice of the ETP management and at the instruction of the ETP Conflicts Committee, Barclays assumed that such projections were reasonably prepared on a basis reflecting the best currently available estimates and judgments of the management of ETE as to the future financial performance of ETP and that ETP will perform substantially in accordance with such projections. With respect to the ETE Unaudited Financial Projections, upon the advice of ETE management and at the instruction of the ETP Conflicts Committee, Barclays assumed that such projections were reasonably prepared on a basis reflecting the best currently available estimates and judgments of the management of ETE as to the future financial performance of ETE and that ETE will perform substantially in accordance with such projections. In arriving at its opinion, Barclays assumed no responsibility for and expressed no view as to any such projections or estimates or the assumptions on which they were based. In connection with rendering its opinion, Barclays assumed that the issuance of the ETE Class A Units will be effected, but Barclays expressed no opinion as to the fairness, from a financial point of view, as to such issuance. In arriving at its opinion, Barclays did not conduct a physical inspection of the properties and facilities of ETP and did not make or obtain any evaluations or appraisals of the assets or liabilities of ETP. In addition, ETP did not authorize Barclays to solicit, and Barclays did not solicit, any indications of interest from any third party with respect to the purchase of all or a part of ETP’s business. Barclays’ opinion was necessarily based upon market, economic and other conditions as they existed on, and could be evaluated as of, August 1, 2018. Barclays assumed no responsibility for updating or revising its opinion based on events or circumstances that may have occurred after August 1, 2018 or may occur after the date of this proxy statement/prospectus. Barclays expressed no opinion as to (i) the prices at which ETP common units would trade following the announcement of the proposed transaction or (ii) the prices at which ETE common units would trade following the announcement or consummation of the proposed transaction. Barclays’ opinion should not be viewed as providing any assurance that the market value of ETE common units to be held by the unaffiliated ETP common unitholders after the consummation of the proposed transaction will be in excess of the market value of ETP common units owned by such unaffiliated ETP common unitholders at any time prior to the announcement or consummation of the proposed transaction.

Barclays assumed the accuracy of the representations and warranties contained in the merger agreement and all the agreements related thereto. Barclays also assumed, upon the advice of ETP, that all material governmental, regulatory and third party approvals, consents and releases for the proposed transaction would be obtained within the constraints contemplated by the Agreement and that the proposed transaction will be consummated in accordance with the terms of the merger agreement without waiver, modification or amendment of any material term, condition or agreement thereof. Barclays did not express any opinion as to any tax or other consequences that might result from the proposed transaction, nor did its opinion address any legal, tax, regulatory or accounting matters, as to which Barclays understood that ETP and the ETP Conflicts Committee had obtained such advice as they deemed necessary from qualified professionals.

In connection with rendering its opinion, Barclays performed certain financial, comparative and other analyses as summarized below. In arriving at its opinion, Barclays did not ascribe a specific range of values to ETP common units or ETE common units but rather made its determination as to fairness, from a financial point of view, to unaffiliated ETP common unitholders of the exchange ratio to be offered to such unaffiliated ETP

67

common unitholders in the proposed transaction on the basis of various financial and comparative analyses. The preparation of a fairness opinion is a complex process and involves various determinations as to the most appropriate and relevant methods of financial and comparative analyses and the application of those methods to the particular circumstances. Therefore, a fairness opinion is not readily susceptible to summary description.

In arriving at its opinion, Barclays did not attribute any particular weight to any single analysis or factor considered by it but rather made qualitative judgments as to the significance and relevance of each analysis and factor relative to all other analyses and factors performed and considered by it and in the context of the circumstances of the particular transaction. Accordingly, Barclays believes that its analyses must be considered as a whole, as considering any portion of such analyses and factors, without considering all analyses and factors as a whole, could create a misleading or incomplete view of the process underlying its opinion.

Summary of Material Financial Analyses

The following is a summary of the material financial analyses performed by Barclays with respect to ETP and ETE in preparing Barclays’ opinion:

Each of these methodologies was used to generate reference per unit equity value ranges for ETP common units and reference per unit equity value ranges for ETE common units. In order to derive implied per unit values in the selected comparable company analysis and the selected precedent transactions analysis, the implied equity value range for ETP and ETE was then divided by an applicable estimate of the number of diluted units estimated to be outstanding. For purposes of the ETP calculations, the number of diluted units outstanding at June 30, 2018, per the ETP Unaudited Financial Projections, was used to derive implied per unit values. The reference per unit equity value ranges were then also used to generate implied exchange ratios for each of these methodologies. For purposes of the ETE calculations, the number of units estimated to be outstanding at June 30, 2018, per the ETE Unaudited Financial Projections, was used to derive implied per unit values. For purposes of its analyses, Barclays utilized the exchange ratio of 1.2800x ETE common units for each ETP common unit to determine an implied equity value of $23.31 per ETP common unit for the proposed transaction based on the price of an ETE common unit at market close on July 31, 2018. For each of the discounted distributable cash flow analysis, the selected comparable company analysis, the selected precedent transactions analysis, and the analysis of public third-party equity research analyst price targets, the implied equity value ranges per ETP common unit and the implied exchange ratios were then compared to the exchange ratio of 1.2800x ETE common units for each ETP common unit in the proposed transaction.

In addition to analyzing the value of ETP common units and ETE common units, to provide additional background and perspective to the ETP Conflicts Committee, Barclays also analyzed and reviewed: (i) the daily historical closing prices of ETP common units and ETE common units and the exchange ratios implied by those closing unit prices for the period from July 31, 2017 to July 31, 2018; (ii) certain publicly available information related to selected affiliated master limited partnership (“MLP”) merger transactions to calculate the size of premiums paid by the acquirers to the acquired company’s unitholders; (iii) the pro forma impact of the proposed transaction on the current and future financial performance and credit profile of the combined company using projected estimates for 2019, 2020, and 2021 for distributable cash flow per unit and distributions per unit for the combined company based on the ETP Unaudited Financial Projections and the ETE Unaudited Financial Projections.

In particular, in applying the various valuation methodologies to the particular businesses, operations and prospects of ETP and ETE, and the particular circumstances of the proposed transaction, Barclays made

qualitative judgments as to the significance and relevance of each analysis. In addition, Barclays made numerous assumptions with respect to industry performance, general business and economic conditions and other matters, many of which are beyond the control of ETP and ETE. Such qualitative judgments and assumptions of Barclays were made following discussions with the managements of each of ETP and ETE. Accordingly, the methodologies and the implied common equity value ranges and implied exchange ratio ranges derived from there must be considered as a whole and in the context of the narrative description of the financial analyses, including the assumptions underlying these analyses. Considering the implied common equity value ranges or the implied exchange ratio ranges without considering the full narrative description of the financial analyses, including the assumptions underlying these analyses, could create a misleading or incomplete view of the process underlying, and conclusions represented by, Barclays’ opinion.

The summary of Barclays’ analyses and reviews provided below is not a complete description of the analyses and reviews underlying Barclays’ opinion. The preparation of a fairness opinion is a complex process involving various determinations as to the most appropriate and relevant methods of analysis and review and the application of those methods to particular circumstances, and, therefore, is not readily susceptible to summary description.

For the purposes of its analyses and reviews, Barclays made numerous assumptions with respect to industry performance, general business, economic, market and financial conditions and other matters, many of which are beyond the control of ETP or any other parties to the proposed transaction. No company, business or transaction considered in Barclays’ analyses and reviews is identical to ETP, ETE, or the proposed transaction, and an evaluation of the results of those analyses and reviews is not entirely mathematical. Rather, the analyses and reviews involve complex considerations and judgments concerning financial and operating characteristics and other factors that could affect the acquisition, public trading or other values of the companies, businesses or transactions considered in Barclays’ analyses and reviews. None of ETP Conflicts Committee, ETP, ETE, Barclays or any other person assumes responsibility if future results are materially different from those discussed. Any estimates contained in these analyses and reviews and the ranges of valuations resulting from any particular analysis or review are not necessarily indicative of actual values or predictive of future results or values, which may be significantly more or less favorable than as set forth below. In addition, analyses relating to the value of companies, businesses or securities do not purport to be appraisals or reflect the prices at which the companies, businesses or securities may actually be sold. Accordingly, the estimates used in, and the results derived from, Barclays’ analyses and reviews are inherently subject to substantial uncertainty.

The summary of the financial analyses and reviews summarized below include information presented in tabular format. In order to fully understand the financial analyses and reviews used by Barclays, the tables must be read together with the text of each summary, as the tables alone do not constitute a complete description of the financial analyses and reviews. Considering the data in the tables below without considering the full description of the analyses and reviews, including the methodologies and assumptions underlying the analyses and reviews, could create a misleading or incomplete view of Barclays’ analyses and reviews.

Discounted Distributable Cash Flow Analysis

In order to estimate the present values of ETP common units and ETE common units, Barclays performed discounted distributable cash flow analyses for each of ETP and ETE. A discounted cash flow analysis is a traditional valuation methodology used to derive an intrinsic valuation of an asset by calculating the “present value” of estimated future cash flows of the asset; in this case, the “present value” of the estimated future distributable cash flows of ETP common units and ETE common units. “Present value” refers to the current value of future cash flows or amounts and is obtained by discounting those future distributable cash flows by a range of discount rates that takes into account macroeconomic assumptions and estimates of risk, the opportunity cost of capital, expected returns, the time value of money, and other appropriate factors.

The discounted distributable cash flow analysis for ETP common units was performed using the ETP Unaudited Financial Projections from 2019 through 2021. To calculate the estimated per ETP common unit

69

equity value ranges in the discounted distributable cash flow analysis, Barclays added (i) projected distributable cash flow per ETP common unit for fiscal years 2019 through 2021 based on the ETP Unaudited Financial Projections to (ii) the terminal value at the end of the forecast period, or the “terminal value” of ETP common units, as of December 31, 2021, and discounted such distributable cash flows per ETP common unit to their net present value as of January 1, 2019 using selected discount rates. Barclays used a nominal discount rate range of 11.5% to 13.5%. This discount rate range was selected by Barclays using its professional judgment and experience, taking into account projected cost of equity capital rates for ETP and the comparable companies utilized in the Selected Comparable Companies Analysis described below. The terminal value of ETP common units was estimated by applying a range of assumed yields of 8.5% to 10.5% to ETP’s estimated distributable cash flow per ETP common unit for 2021. The assumed yields were selected by Barclays based on Barclays’ professional judgment and experience, taking into account the yields of ETP and the selected comparable companies utilized in the Selected Comparable Companies Analysis described below. The reference equity value range per ETP common unit yielded by the ETP discounted distributable cash flow analysis implied an equity value range for ETP common units of $26.00 to $31.00 per ETP Common Unit, as compared to the closing ETP common unit price of $20.96 on July 31, 2018.

To calculate the estimated per ETE common unit equity value ranges in the discounted distributable cash flow analysis for ETE, Barclays added (i) projected distributable cash flow per ETE common unit for fiscal years 2019 through 2021 based on the ETE Unaudited Financial Projections to (ii) the terminal value of ETE common units, as of December 31, 2021, and discounted such distributable cash flows per ETE common unit to their net present value as of January 1, 2019 using a nominal discount rate range of 12.0% to 14.0%. This discount rate range was selected by Barclays using its professional judgment and experience, taking into account projected cost of equity capital rates for ETE and the selected comparable companies utilized in the Selected Comparable Companies Analysis described below. The terminal value of ETE common units was estimated by applying a range of assumed yields of 5.75% to 7.75% to ETE’s 2021 estimated distributable cash flow per ETE common unit. The assumed yields were selected by Barclays based on Barclays’ professional judgment and experience, taking into account the yields of ETE and the selected comparable companies utilized in the Selected Comparable Companies Analysis described below. The reference equity value range for ETE common units yielded by the ETE discounted distributable cash flow analysis implied an equity value range for ETE of $18.00 to $23.50 per ETE common unit, as compared to the closing ETE common unit price of $18.21 on July 31, 2018.

Using the implied reference equity value per unit ranges for each of ETP common units and ETE common units, Barclays derived reference implied exchange ratio ranges of 1.1064x to 1.7222x.

Barclays noted that the exchange ratio of 1.2800x to be offered to unaffiliated ETP common unitholders in the proposed transaction was in line with the implied exchange ratio range yielded by Barclays’ discounted distributable cash flow analysis.

Selected Comparable Company Analysis

In order to assess how the public market values units of similar publicly traded midstream corporations and MLPs and to provide a range of relative implied equity values per ETP common unit and per ETE common unit by reference to those companies, which could then be used to calculate implied exchange ratio ranges, Barclays reviewed and compared specific financial and operating data relating to ETP and ETE to that of midstream corporations and MLPs selected by Barclays based on Barclays’ experience with midstream corporations and MLPs.

The midstream corporations and MLPs selected with respect to ETP were:

70

Barclays calculated and compared various financial multiples and ratios of ETP and ETE and the selected comparable companies. As part of its selected comparable company analysis, Barclays calculated and analyzed distributable cash flow per unit yields and enterprise value (“EV”) divided by earnings before interest, taxes, depreciation and amortization (“EBITDA”) multiples using published estimates by third party equity research analysts for estimated distributable cash flow per unit and EBITDA in 2019 for each of the comparable companies selected and for ETP using the ETP Unaudited Financial Projections. All of these calculations were performed, and based on publicly available financial data including Factset and closing prices, as of July 31, 2018, the last trading date prior to the delivery of Barclays’ opinion. The results of the ETP selected comparable company analysis are summarized below:

Barclays selected the comparable midstream corporations and MLPs listed above because their business and operating profiles are reasonably similar to that of ETP. However, because of the inherent differences between the business, operations and prospects of ETP and those of the selected comparable companies, Barclays believed that it was inappropriate to, and therefore did not, rely solely on the quantitative results of the selected comparable company analysis. Accordingly, Barclays also made certain qualitative judgments concerning differences between the business, financial and operating characteristics and prospects of ETP and the selected comparable companies that could affect the public trading values of each in order to provide a context in which to consider the results of the quantitative analysis. These qualitative judgments related primarily to the differing sizes, growth prospects, profitability levels and degrees of operational risk between ETP and the selected midstream corporations and MLPs included in the selected comparable company analysis. The equity value range for ETP common units yielded by the ETP selected comparable company analysis implied a reference equity value range for ETP of $24.00 to $34.00 per ETP common unit.

The general partners selected with respect to ETE were:

71

Barclays calculated and analyzed the implied general partner value as a multiple of general partner distributions using published estimates by third party equity research analysts for estimated general partner distributions in 2019 and 2020 for each of the comparable companies selected and for ETE using the ETE Unaudited Financial Projections. The results of the ETE selected comparable company analysis are summarized below:

Barclays selected the comparable general partners listed above because their business and operating profiles are reasonably similar to that of ETE. However, because of the inherent differences between the business, operations and prospects of ETE and those of the selected comparable companies, Barclays believed that it was inappropriate to, and therefore did not, rely solely on the quantitative results of the selected comparable company analysis. Accordingly, Barclays also made certain qualitative judgments concerning differences between the business, financial and operating characteristics and prospects of ETE and the selected comparable companies that could affect the public trading values of each in order to provide a context in which to consider the results of the quantitative analysis. These qualitative judgments related primarily to the differing sizes, growth prospects, profitability levels and degrees of operational risk between ETE and the selected general partners included in the selected comparable company analysis. The equity value range for ETE common units yielded by the ETE comparable company analysis implied a reference equity value range for ETE of $17.50 to $23.50 per ETE common unit.

Using the implied reference equity value per unit ranges for each of ETP and ETE, Barclays derived a reference implied exchange ratio range of 1.0213x to 1.9429x.

Barclays noted that the exchange ratio of 1.2800x to be offered to unaffiliated ETP common unitholders in the proposed transaction was in line with the implied exchange ratio range yielded by Barclays’ selected comparable companies analysis.

Selected Precedent Transactions Analysis

Barclays reviewed and compared the purchase prices and financial multiples paid in selected other MLP transactions that Barclays deemed relevant based on its experience with merger and acquisition transactions, particularly in the MLP industry. Barclays chose such MLP merger transactions based on, among other things, the similarity of the applicable companies to ETP and ETE with respect principally to size and operational focus. Each of the selected transactions was an acquisition of an MLP announced between June 2009 and July 2018. None of the transactions selected based on the criteria were subsequently excluded in conducting this analysis. The following list sets forth the transactions analyzed based on such characteristics:

Using publicly available information, Barclays calculated and analyzed multiples of EV to last twelve month (“LTM”) EBITDA (“LTM EBITDA”) represented by the prices paid in the above selected precedent transactions. The results of the selected precedent transactions analysis are summarized below:

The reasons for and the circumstances surrounding each of the selected precedent transactions analyzed were diverse and there are inherent differences between the businesses, operations, financial conditions and prospects of ETP and the MLPs included in the selected precedent transactions analysis. Accordingly, Barclays believed that a purely quantitative selected precedent transactions analysis would not be particularly meaningful in the context of considering the proposed transaction. Barclays therefore made qualitative judgments concerning

73

differences between the characteristics of the selected precedent transactions and the proposed transaction which would affect the acquisition values of the selected target companies and ETP. Based upon these judgments, Barclays’ selected precedent transactions analysis yielded a reference equity value range for ETP common units of $23.00 to $36.00 per ETP common unit.

Barclays also reviewed and compared the purchase prices and financial multiples paid in selected other transactions, specifically those transactions involving a general partner or the general partner’s GP and IDR interests, that Barclays deemed relevant based on its experience with merger and acquisition transactions. Barclays chose such general merger transactions based on, among other things, the similarity of the applicable companies to ETE with respect principally to size and operational focus and because the organizations involved are all structured as general partners. Each of the selected transactions was an acquisition of a general partner announced between June 2014 and July 2018. None of the transactions selected based on the criteria were subsequently excluded in conducting this analysis. The following list sets forth the transactions analyzed based on such characteristics:

Using publicly available information, Barclays calculated and analyzed multiples of the value of the general partner to latest quarter annualized (“LQA”) distributions to the general partner represented by the prices paid in the selected precedent transactions. The results of the selected precedent transactions analysis are summarized below:

The reasons for and the circumstances surrounding each of the selected precedent transactions analyzed were diverse and there are inherent differences between the businesses, operations, financial conditions and prospects of ETE and the general partners included in the selected precedent transactions analysis. Accordingly, Barclays believed that a purely quantitative selected precedent transactions analysis would not be particularly meaningful in the context of considering the proposed transaction. Barclays therefore made qualitative judgments concerning differences between the characteristics of the selected precedent transactions and the proposed

74

transaction which would affect the acquisition values of the selected target companies and ETE. Based upon these judgments, Barclays’ selected precedent transactions analysis yielded a reference equity value range for ETE common units of $18.50 to $29.00 per ETE common unit.

Using the implied reference equity value per unit ranges for each of ETP common units and ETE common units, Barclays also derived a reference implied exchange ratio range of 0.7931x to 1.9459x.

Barclays noted that the exchange ratio of 1.2800x to be offered to unaffiliated ETP common unitholders in the proposed transaction was in line with the implied exchange ratio range yielded by Barclays’ selected precedent transactions analysis.

Other Factors

Analysis of Equity Research Analyst Price Targets

Barclays reviewed and compared, as of July 31, 2018, the publicly available price targets of ETP common units and ETE common units published by equity research analysts associated with various Wall Street firms, of which there were 10 (including Barclays’ equity research analyst price targets for each of ETP and ETE). The research analysts’ price targets per ETP common unit ranged from $20.00 to $31.00 and per ETE common unit ranged from $17.00 to $23.00. The publicly available unit price targets published by such equity research analysts do not necessarily reflect the current market trading prices for ETP common units or ETE common units and these estimates are subject to uncertainties, including future financial performance of ETP and ETE and future market conditions.

Historical Common Unit Trading Analysis

To provide background information and perspective with respect to the historical unit prices of ETP common units and ETE common units, Barclays reviewed the daily historical closing unit prices of ETP common units and ETE common units for the period from July 31, 2017 to July 31, 2018. Barclays analyzed the ratio of the daily closing price per ETP common unit to the corresponding closing price per ETE common unit over such period. Over the period, the implied relative exchange ratio ranged from a low of 0.9273x to a high of 1.1994x ETE common units per ETP common unit. In addition, Barclays reviewed the implied relative exchange ratio of the closing price per ETP common unit and closing price per ETE common unit based on July 31, 2018 closing prices and 5-day, 10-day, and 30-day volume-weighted average prices (“VWAP”), respectively, as of July 31, 2018. This analysis implied relative exchange ratios ranging from a low of 1.1251x to a high of 1.1466x ETE common units per ETP common unit, which Barclays noted was in line with the exchange ratio to be offered to unaffiliated ETP common unitholders in the proposed transaction.

Premiums Analysis

In order to provide background information and perspective to, and to assess the implied premium offered to unaffiliated ETP common unitholders in the proposed transaction, Barclays reviewed and analyzed the implied premium levels in the proposed transaction based on the “Heads-Up” exchange ratios, which reflects the implied exchange ratio of ETP common unit trading prices and ETE common unit trading prices without considering any adjustments, as of July 31, 2018 and the 5-day, 10-day, and 30-day VWAP of ETP common units and ETE common units. The table below sets forth the summary results of the analysis:
