MERGER PROPOSAL—YOUR VOTE IS VERY IMPORTANT

Dear EnLink Midstream Partners, LP Unitholders:

              On October 21, 2018, EnLink Midstream, LLC ("ENLC"), EnLink Midstream Manager, LLC, the managing member of ENLC ("EMM"), NOLA Merger Sub, LLC, a wholly-owned subsidiary of ENLC ("Merger Sub"), EnLink Midstream Partners, LP ("ENLK"), and EnLink Midstream GP, LLC, the general partner of ENLK ("EGP"), entered into an Agreement and Plan of Merger (the "Merger Agreement"). Pursuant to the Merger Agreement, subject to the satisfaction or waiver of certain conditions in the Merger Agreement, Merger Sub will merge with and into ENLK (the "Merger"), with ENLK surviving the Merger as a subsidiary of ENLC. At the effective time of the Merger (the "Effective Time"), each issued and outstanding common unit representing a limited partner interest in ENLK (collectively, the "ENLK Common Units") other than any ENLK Common Units held directly or indirectly by ENLC and its subsidiaries (collectively, the "ENLK Public Units") will be converted into the right to receive 1.15 (the "Exchange Ratio") common units representing limited liability company interests in ENLC (collectively, the "ENLC Common Units," and such consideration, the "Merger Consideration"). No fractional ENLC Common Units will be issued in the Merger. All fractional ENLC Common Units that a holder of ENLK Common Units (an "ENLK Common Unitholder") would otherwise be entitled to receive as merger consideration (after taking into account all ENLK Common Units held by such ENLK Common Unitholder) will be aggregated and then, if a fractional ENLC Common Unit results from that aggregation, be rounded up to the nearest whole ENLC Common Unit.

              Pursuant to the Merger Agreement, ENLK will hold a special meeting of the ENLK Common Unitholders and the holder(s) of the Series B Cumulative Convertible Preferred Units representing limited partner interests in ENLK (the "ENLK Series B Units") (such holder(s), collectively, the "ENLK Series B Unitholders," and together with the ENLK Common Unitholders, the "ENLK Voting Unitholders") in connection with the proposed Merger Agreement. At the special meeting of the ENLK Voting Unitholders (the "ENLK Unitholder Meeting"), the ENLK Voting Unitholders will be asked to (i) vote on the proposal to approve the Merger Agreement (the "ENLK Merger Proposal") and (ii) approve the adjournment of the ENLK Unitholder Meeting to a later date or dates, if necessary or appropriate, to solicit additional proxies in the event there are not sufficient votes at the time of the ENLK Unitholder Meeting to approve the ENLK Merger Proposal (the "ENLK Adjournment Proposal"). Approval of the ENLK Merger Proposal requires the affirmative vote of holders of at least a majority of the ENLK Common Units and ENLK Series B Units (collectively, the "ENLK Voting Units") issued and outstanding and entitled to vote on the approval of the ENLK Merger Proposal, voting together as a single class. Concurrently with the execution of the Merger Agreement, ENLK entered into (i) a Support Agreement, among GIP III Stetson I, L.P. ("GIP Stetson I"), ENLC, Acacia Natural Gas Corp I, Inc., a wholly-owned subsidiary of ENLC ("Acacia"), EnLink Midstream, Inc., a wholly-owned subsidiary of ENLC ("EMI," and together with GIP Stetson I and Acacia, the "Supporting Common Unitholders"), and ENLK, pursuant to which GIP Stetson I, Acacia, and EMI, the Supporting Common Unitholders, agreed, among other things, to vote their ENLK Common Units in favor of the approval of the ENLK Merger Proposal, and (ii) a Support Agreement, among Enfield Holdings, L.P., the record holder of all of the ENLK Series B Units ("Enfield," and together with the Supporting Common Unitholders, the "Supporting Voting Unitholders"), TPG VII Management, LLC, WSEP Egypt Holdings, LP, WSIP Egypt Holdings, LP, and ENLK, pursuant to which Enfield agreed, among other things, to vote its ENLK Series B Units in favor of the approval of the ENLK Merger Proposal. The Supporting Voting Unitholders collectively own ENLK Voting Units representing approximately 58.8% of the outstanding ENLK Voting Units. As a result, the affirmative vote by the Supporting Voting Unitholders will be sufficient to approve the ENLK Merger Proposal and, if necessary, the ENLK Adjournment Proposal.

              If a quorum is present at the ENLK Unitholder Meeting, the ENLK Adjournment Proposal requires approval by the affirmative vote of holders of a majority of the ENLK Voting Units issued and outstanding and entitled to vote. If a quorum is not present, the ENLK Adjournment Proposal requires approval by the affirmative vote of holders of a majority of the outstanding ENLK Voting Units represented either in person or by proxy at the ENLK Unitholder Meeting.

              On October 21, 2018, the Conflicts Committee (the "ENLK Conflicts Committee") of the Board of Directors of EGP (the "ENLK Board") unanimously determined that the Merger Agreement and the transactions contemplated thereby and by the other documents contemplated by the Merger Agreement (collectively with the Merger Agreement, the "Transaction Documents"), including the Merger (collectively, the "Transactions"), are fair and reasonable to, and in the best interest of, ENLK and the holders of ENLK Common Units other than EGP, ENLC, GIP Stetson I, and their respective affiliates (the "ENLK Unaffiliated Unitholders"), and unanimously approved the Merger Agreement, the other Transaction Documents, and the Transactions, including the Merger, which approval constituted "Special Approval" under the Ninth Amended and Restated Agreement of Limited Partnership of ENLK, dated as of September 21, 2017, as amended. The ENLK Conflicts Committee also recommended that the ENLK Board approve the Merger Agreement, the Transaction Documents, and the Transactions, including the Merger, and resolved, and recommended that the ENLK Board resolve, to recommend that the ENLK Voting Unitholders approve the Merger Agreement. On October 21, 2018, the ENLK Board, acting upon the recommendation of the ENLK Conflicts Committee, unanimously (i) determined that the Merger Agreement, the other Transaction Documents, and the Transactions, including the Merger, are in the best interest of ENLK and the ENLK Unaffiliated Unitholders, (ii) approved the Merger Agreement, the other Transaction Documents, and the Transactions, and directed that the Merger Agreement be submitted to a vote of the ENLK Voting Unitholders, and (iii) determined to recommend that the ENLK Voting Unitholders approve the Merger Agreement.

              On October 21, 2018, the Conflicts Committee (the "ENLC Conflicts Committee") of the Board of Directors of EMM (the "ENLC Board") unanimously determined that the Merger Agreement, the other Transaction Documents, and the Transactions are fair to, and in the best interest of, ENLC and the holders of ENLC Common Units other than GIP III Stetson II, L.P. ("GIP Stetson II") and its affiliates, and unanimously approved the Merger Agreement, the other Transaction Documents, and the Transactions, including the Merger, the issuance by ENLC of ENLC Common Units as Merger Consideration (the "ENLC Merger Issuance"), the issuance by ENLC of a new class of limited liability company interests pursuant to the Transaction Documents (the "ENLC Class C Issuance"), and the issuance by ENLC of ENLC Common Units upon exchange of ENLK Series B Units pursuant to the Transaction Documents (the "ENLC Exchange Issuance" and, together with the ENLC Merger Issuance and the ENLC Class C Issuance, the "ENLC Unit Issuance"), which approval constituted "Special Approval" under the First Amended and Restated Operating Agreement of ENLC, dated as of March 7, 2014 (the "ENLC Operating Agreement"). The ENLC Conflicts Committee also recommended that the ENLC Board approve the Merger Agreement, the Transaction Documents, and the Transactions, including the ENLC Unit Issuance, and determined to recommend that the holders of ENLC Common Units approve the ENLC Unit Issuance. On October 21, 2018, the ENLC Board, acting upon the recommendation of the ENLC Conflicts Committee, unanimously (i) determined that the Merger Agreement, the other Transaction Documents, and the Transactions, including the ENLC Common Unit Issuance, are in the best interest of ENLC and the holders of ENLC Common Units, (ii) approved the Merger Agreement, the other Transaction Documents, and the Transactions, (iii) authorized, pursuant to the ENLC Operating Agreement, GIP Stetson II, as the holder of the majority of the outstanding ENLC Common Units, to act by written consent with respect to its approval of the ENLC Unit Issuance, (iv) directed that the ENLC Unit Issuance be submitted for approval by GIP Stetson II, in its capacity as the holder of a majority of the outstanding ENLC Common Units (the "ENLC Majority Holder"), and (v) determined to recommend that the ENLC Majority Holder approve the ENLC Unit Issuance. Concurrently with the execution of the Merger Agreement, the ENLC Majority Holder approved the ENLC Unit Issuance by written consent (the "ENLC Written Consent"). The ENLC Written Consent constitutes the requisite approval of the holders of ENLC Common Units under Rule 312.03(c) of the Listed Company Manual of the New York Stock Exchange (the "NYSE") to approve the ENLC Unit Issuance.

              We cannot complete the Merger unless the ENLK Voting Unitholders approve the ENLK Merger Proposal. Accordingly, your vote is very important regardless of the number of ENLK Common Units and/or ENLK Series B Units you own. Voting instructions are set forth inside this joint information statement/proxy statement/prospectus.

              The ENLK Conflicts Committee and the ENLK Board each recommend that the ENLK Voting Unitholders vote "FOR" the ENLK Merger Proposal. The ENLK Board recommends that the ENLK Voting Unitholders vote "FOR" the ENLK Adjournment Proposal. ENLK Voting Unitholders should be aware that some of EGP's directors and executive officers may have interests in the Merger that are different from, or in addition to, the interests they may have as ENLK Voting Unitholders. See "Certain Relationships; Interests of Certain Persons in the Merger."

              This joint information statement/proxy statement/prospectus provides you with detailed information about the proposed Transactions and related matters. ENLK encourages you to read the entire document carefully. In particular, please read "Risk Factors" beginning on page 21 of this joint information statement/proxy statement/prospectus for a discussion of risks relevant to the Transactions and ENLC's business following the Transactions.

              The Exchange Ratio is fixed and will not be adjusted on account of any change in price of either the ENLC Common Units or ENLK Common Units prior to completion of the Merger. Upon the closing of the Merger, it is estimated that former ENLK Common Unitholders and current ENLC Unitholders will own approximately 62.7% and 37.3%, respectively, of the ENLC Common Units.

              The ENLC Common Units are listed on the NYSE under the symbol "ENLC," and the ENLK Common Units are listed on the NYSE under the symbol "ENLK." The last reported sale price of the ENLC Common Units on the NYSE on December 7, 2018 was $11.53 per unit. The last reported sale price of the ENLK Common Units on the NYSE on December 7, 2018 was $13.34 per unit.

Notice of Special Meeting of Unitholders
To Be Held on January 23, 2019

To the Unitholders of EnLink Midstream Partners, LP:

        A special meeting (the "ENLK Unitholder Meeting") of the holders of common units representing limited partner interests ("ENLK Common Units") in EnLink Midstream Partners, LP ("ENLK") and holders of Series B Cumulative Convertible Preferred Units representing limited partner interests in ENLK ("ENLK Series B Units") will be held on January 23, 2019 at 10:00 a.m., Central Time, at 1722 Routh Street, First Floor Conference Center, Dallas, Texas 75201, for the following purposes:

        Pursuant to the Ninth Amended and Restated Agreement of Limited Partnership of ENLK, dated as of September 21, 2017, as amended (the "ENLK Partnership Agreement"), approval of the ENLK Merger Proposal requires the affirmative vote of holders of at least a majority of the ENLK Common Units and ENLK Series B Units issued and outstanding and entitled to vote on the approval of the ENLK Merger Proposal, voting together as a single class (collectively, the "ENLK Voting Units," and such holders of ENLK Voting Units, the "ENLK Voting Unitholders"). If a quorum is present at the ENLK Unitholder Meeting, the ENLK Adjournment Proposal requires approval by the affirmative vote of holders of a majority of the ENLK Voting Units issued and outstanding and entitled to vote. If a quorum is not present, the ENLK Adjournment Proposal requires approval by the affirmative vote of holders of a majority of the outstanding ENLK Voting Units represented either in person or by proxy at the ENLK Unitholder Meeting. Abstentions will have the same effect as votes against the ENLK Merger Proposal and the ENLK Adjournment Proposal. Assuming there is a quorum, failures to vote and broker non-votes (if any) will have the same effect as votes against the ENLK Merger Proposal and the ENLK Adjournment Proposal. If no quorum is present, broker non-votes (if any) will have the same effect as votes against the ENLK Merger Proposal and the ENLK Adjournment Proposal, but failures to vote will have no effect on the ENLK Adjournment Proposal.

        Concurrently with the execution of the Merger Agreement, ENLK entered into (i) a Support Agreement, among GIP III Stetson I, L.P. ("GIP Stetson I"), ENLC, Acacia Natural Gas Corp I, Inc.,


Table of Contents

a wholly-owned subsidiary of ENLC ("Acacia"), EnLink Midstream, Inc., a wholly-owned subsidiary of ENLC ("EMI," and together with GIP Stetson I and Acacia, the "Supporting Common Unitholders"), and ENLK, pursuant to which GIP Stetson I, Acacia, and EMI, the Supporting Common Unitholders, agreed, among other things, to vote their ENLK Common Units in favor of the approval of the ENLK Merger Proposal, and (ii) a Support Agreement, among Enfield Holdings, L.P. ("Enfield," and together with the Supporting Common Unitholders, the "Supporting Voting Unitholders"), TPG VII Management, LLC, WSEP Egypt Holdings, LP, WSIP Egypt Holdings, LP, and ENLK, pursuant to which Enfield agreed, among other things, to vote its ENLK Series B Units in favor of the approval of the ENLK Merger Proposal. The Supporting Voting Unitholders collectively own ENLK Voting Units representing approximately 58.8% of the outstanding ENLK Voting Units. As a result, the affirmative vote by the Supporting Voting Unitholders will be sufficient to approve the ENLK Merger Proposal and, if necessary, the ENLK Adjournment Proposal.

        We cannot complete the Merger unless the ENLK Voting Unitholders approve the ENLK Merger Proposal. Accordingly, your vote is very important regardless of the number of ENLK Common Units and/or ENLK Series B Units you own.

        On October 21, 2018, the Conflicts Committee (the "ENLK Conflicts Committee") of the Board of Directors of EGP (the "ENLK Board") unanimously determined that the Merger Agreement and the transactions contemplated thereby and by the other documents contemplated by the Merger Agreement (collectively with the Merger Agreement, the "Transaction Documents"), including the Merger (collectively, the "Transactions"), are fair and reasonable to, and in the best interest of, ENLK and the holders of ENLK Common Units other than EGP, ENLC, GIP Stetson I, and their respective affiliates (the "ENLK Unaffiliated Unitholders"), and unanimously approved the Merger Agreement, the other Transaction Documents, and the Transactions, including the Merger, which approval constituted "Special Approval" under the ENLK Partnership Agreement. The ENLK Conflicts Committee also recommended that the ENLK Board approve the Merger Agreement, the Transaction Documents, and the Transactions, including the Merger, and resolved, and recommended that the ENLK Board resolve, to recommend that the ENLK Voting Unitholders approve the Merger Agreement. On October 21, 2018, the ENLK Board, acting upon the recommendation of the ENLK Conflicts Committee, unanimously (i) determined that the Merger Agreement, the other Transaction Documents, and the Transactions, including the Merger, are in the best interest of ENLK and the ENLK Unaffiliated Unitholders, (ii) approved the Merger Agreement, the other Transaction Documents, and the Transactions, and directed that the Merger Agreement be submitted to a vote of the ENLK Voting Unitholders, and (iii) determined to recommend that the ENLK Voting Unitholders approve the Merger Agreement. For more information regarding the recommendation of the ENLK Conflicts Committee, see "The Merger—Recommendation of the ENLK Conflicts Committee and the ENLK Board, and the Reasons of the ENLK Conflicts Committee for Recommending Approval of the Transactions."

        ENLK Voting Unitholders should be aware that some of EGP's directors and executive officers may have interests in the Merger that are different from, or in addition to, the interests they may have as ENLK Voting Unitholders. See "Certain Relationships; Interests of Certain Persons in the Merger."

Q:
What happens to distributions after the Merger?
Q.
How does each of the ENLK Conflicts Committee and the ENLK Board recommend that I vote?

A.
The ENLK Conflicts Committee unanimously determined that the Merger Agreement and Transactions, including the Merger, are fair and reasonable to, and in the best interest of, ENLK and the ENLK Unaffiliated Unitholders, and unanimously approved the Merger Agreement, the other Transaction Documents, and the Transactions, including the Merger, which approval constituted "Special Approval" under the ENLK Partnership Agreement.

Q:
What are the expected material U.S. federal income tax consequences to an ENLK Common Unitholder as a result of the Merger?

A:
The receipt of ENLC Common Units in exchange for ENLK Common Units pursuant to the Merger Agreement will be a taxable transaction to U.S. Holders (as defined in the section titled "Material U.S. Federal Income Tax Consequences") for U.S. federal income tax purposes. As a result, a U.S. Holder will generally recognize (i) ordinary income to the extent of the U.S. Holder's share of depreciation recapture, other "unrealized receivables," and "inventory items" owned by ENLK and its subsidiaries and (ii) capital gain or capital loss equal to the difference between the U.S. Holder's amount realized and the sum of the U.S. Holder's tax basis in its ENLK Common Units and the amount of ordinary income recognized by the U.S. Holder as described in clause (i). A U.S. Holder's passive losses in respect of its ENLK Common Units that were not deductible by the U.S. Holder in prior taxable periods may become available to offset a portion of the gain recognized by such U.S. Holder. See the section titled "Material U.S. Federal Income Tax Consequences" for a more complete discussion of certain U.S. federal income tax consequences of the Merger.

Q:
What are the expected material U.S. federal income tax consequences for an ENLK Common Unitholder of the ownership of ENLC Common Units after the Merger is completed?

A:
ENLC is classified as a corporation for U.S. federal income tax purposes and is subject to U.S. federal income tax on its taxable income. A distribution of cash by ENLC to an ENLC Unitholder who is a U.S. Holder will generally be included in such U.S. Holder's income as ordinary dividend income to the extent of ENLC's current or accumulated "earnings and profits," as determined under U.S. federal income tax principles. A portion of the cash distributed to ENLC Unitholders by ENLC after the Merger may exceed ENLC's current and accumulated earnings and profits. Distributions of cash in excess of ENLC's current and accumulated earnings and profits will be treated as a non-taxable return of capital, reducing a U.S. Holder's adjusted tax basis in such holder's ENLC Common Units and, to the extent the distribution exceeds such holder's adjusted tax basis, as capital gain from the sale or exchange of such ENLC Common Units (provided such ENLC Common Units are capital assets in the hands of the U.S. Holder). See the section titled "Material U.S. Federal Income Tax Consequences" for a more complete discussion of certain U.S. federal income tax consequences of owning and disposing of ENLC Common Units.

Q.
Are ENLK Common Unitholders entitled to appraisal rights in connection with the Merger?

A.
No. ENLK Common Unitholders do not have appraisal rights under applicable law or contractual appraisal rights under the ENLK Partnership Agreement or the Merger Agreement.

Questions and Answers Specific to ENLC Unitholders

Q.
Why did the ENLC Unit Issuance require approval of the ENLC Unitholders?

A.
Because ENLC Common Units are listed on the NYSE, ENLC is subject to NYSE rules and regulations. Section 312.03 of the NYSE Listed Company Manual requires unitholder approval prior to the issuance of ENLC Common Units, or securities convertible into or exercisable for ENLC Common Units, in any transaction or series of transactions if (i) the ENLC Common Units to be issued have, or will have upon issuance, voting power equal to or in excess of 20% of the voting power outstanding before the issuance of such ENLC Common Units or of securities convertible into or exercisable for ENLC Common Units, or (ii) the number of ENLC Common Units to be issued is, or will be upon issuance, equal to or in excess of 20% of the number of ENLC Common Units outstanding before the issuance of ENLC Common Units or of securities convertible into or exercisable for ENLC Common Units.

Voting Unitholder providing the proxy is a holder of record on December 18, 2018, the record date. If you are not a holder of record on the record date, any proxy you deliver will be invalid and will not be counted at the ENLK Unitholder Meeting. If you deliver a proxy prior to the record date and remain a holder on the record date, you do not need to deliver another proxy after the record date. If you deliver a proxy prior to the record date and do not revoke that proxy, your proxy will be deemed to cover the number of ENLK Voting Units you own on the record date even if that number is different from the number of ENLK Voting Units you owned when you executed and delivered your proxy. Proxies received from persons who are not holders of record on the record date will not be effective. ENLK Common Unitholders have one vote per ENLK Common Unit on each proposal to be voted upon. In addition, for each proposal to be voted upon, ENLK Series B Unitholders have one vote for each ENLK Common Unit into which each ENLK Series B Unit is convertible based on the conversion rate in effect as of the close of business on the record date for the ENLK Unitholder Meeting, which conversion rate is currently one ENLK Common Unit for each ENLK Series B Unit. As of the date of this joint information statement/proxy statement/prospectus, there were 353,105,507 ENLK Common Units and 58,728,994 ENLK Series B Units outstanding for a total of 411,834,501 ENLK Voting Units outstanding.

        Votes may be cast in person at the ENLK Unitholder Meeting or by proxy.

        Concurrently with the execution of the Merger Agreement, ENLC, GIP Stetson I, Acacia, and EMI entered into the ENLK Support Agreement with ENLK, pursuant to which, GIP Stetson I, Acacia, and EMI, the Supporting Common Unitholders, agreed to, among other things and while the ENLK Support Agreement remains in effect, vote the 183,189,051 ENLK Common Units (representing approximately 44.5% of the outstanding ENLK Voting Units) held of record and beneficially by the Supporting Common Unitholders in favor of the approval of the ENLK Merger Proposal.

        The directors and executive officers of EMM and EGP beneficially own, collectively, 1,385,231 ENLK Common Units, representing approximately 0.4% of the outstanding ENLK Common Units. ENLK and ENLC currently expect that the directors and executive officers of EMM and EGP will vote their ENLK Common Units in favor of the approval of the ENLK Merger Proposal, although none of them has entered into any agreements obligating them to do so.

        In addition, concurrently with the execution of the Merger Agreement, the Enfield Parties and ENLK entered into the Enfield Support Agreement, pursuant to which, among other things and while the Enfield Support Agreement remains in effect, Enfield agreed to vote the ENLK Series B Units that it held as of such time and any additional ENLK Series B Units it acquired in favor of the approval of the ENLK Merger Proposal. Enfield holds 58,728,994 ENLK Series B Units of record (representing approximately 14.3% of the outstanding ENLK Voting Units).

        The Supporting Voting Unitholders collectively own ENLK Voting Units representing approximately 58.8% of the outstanding ENLK Voting Units. As a result, the affirmative vote by the Supporting Voting Unitholders will be sufficient to approve the ENLK Merger Proposal and, if necessary, the ENLK Adjournment Proposal.

The ENLC Conflicts Committee also recommended that the ENLC Board approve the Merger Agreement, the Transaction Documents, and the Transactions, including the ENLC Unit Issuance, and determined to recommend that the ENLC Unitholders approve the ENLC Unit Issuance. In evaluating the Merger Agreement, the other Transaction Documents, and the Transactions, the ENLC Conflicts Committee considered information supplied by management of EnLink, consulted with its legal and financial advisors, and considered a number of factors in reaching its determination, approval and recommendation.

        Later on October 21, 2018, the ENLC Board, acting upon the recommendation of the ENLC Conflicts Committee, unanimously (i) determined that the Merger Agreement, the other Transaction Documents, and the Transactions, including the ENLC Common Unit Issuance, are in the best interest of ENLC and the holders of ENLC Common Units, (ii) approved the Merger Agreement, the other Transaction Documents, and the Transactions, (iii) authorized, pursuant to the ENLC Operating Agreement, GIP Stetson II, as the ENLC Majority Holder, to act by written consent with respect to its approval of the ENLC Unit Issuance, (iv) directed that the ENLC Unit Issuance be submitted for approval by GIP Stetson II, in its capacity as the ENLC Majority Holder, and (v) determined to recommend that the ENLC Majority Holder approve the ENLC Unit Issuance. Concurrently with the execution of the Merger Agreement, the ENLC Majority Holder executed the ENLC Written Consent, which constitutes the requisite approval of the holders of ENLC Common Units under Rule 312.03(c) of the Listed Company Manual of the NYSE to approve the ENLC Unit Issuance.

Opinion of Barclays—Financial Advisor to the ENLC Conflicts Committee (see page 53)

        In connection with the Transactions, the ENLC Conflicts Committee received, on October 21, 2018, an oral opinion from Barclays Capital Inc. ("Barclays"), which was subsequently confirmed in writing, as to the fairness, as of the date of the opinion and based upon and subject to the qualifications, limitations and assumptions stated therein, from a financial point of view, to ENLC of the Exchange Ratio to be paid by ENLC in the Transactions.

        The full text of Barclays' written opinion, which is attached to this joint information statement/proxy statement/prospectus as Annex F, sets forth, among other things, the assumptions made, procedures followed, factors considered and limitations on the review undertaken by Barclays in rendering its opinion. You are encouraged to read the opinion carefully and in its entirety.

Barclays expressed no view as to, and its opinion does not in any manner address, the underlying business decision to proceed with or effect the Transactions, the likelihood of consummation of the Transactions, or the relative merits of the Transactions as compared to any other transaction or business strategy in which ENLC might engage. In addition, Barclays expressed no view as to, and Barclays' opinion did 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 Transactions, or any class of such persons, relative to the Exchange Ratio in the Transactions or otherwise. The summary of Barclays' opinion provided in this joint information statement/proxy statement/prospectus is qualified in its entirety by reference to the full opinion. Barclays' opinion is not intended to be and does not constitute a recommendation to any unitholder of ENLC or any other person as to how such unitholder or other person should vote with respect to the Transactions.

Recommendation of the ENLK Conflicts Committee and the ENLK Board, and the Reasons of the ENLK Conflicts Committee for Recommending Approval of the Transactions (see page 65)

        On October 21, 2018, the ENLK Conflicts Committee unanimously determined that the Merger Agreement and Transactions, including the Merger, are fair and reasonable to, and in the best interest of, ENLK and the ENLK Unaffiliated Unitholders, and unanimously approved the Merger Agreement, the other Transaction Documents, and the Transactions, including the Merger, which approval constituted "Special Approval" under the ENLK Partnership Agreement. The ENLK Conflicts Committee also recommended that the ENLK Board approve the Merger Agreement, the Transaction Documents, and the Transactions, including the Merger, and resolved, and recommended that the ENLK Board resolve, to recommend that the ENLK Voting Unitholders approve the Merger Agreement. In evaluating the Merger Agreement, the other Transaction Documents, and the Transactions, the ENLK Conflicts Committee considered information supplied by management of EnLink, consulted with its legal and financial advisors, and considered a number of factors in reaching its determination, approval and recommendation.

        Later on October 21, 2018, the ENLK Board, acting upon the recommendation of the ENLK Conflicts Committee, unanimously (i) determined that the Merger Agreement, the other Transaction Documents, and the Transactions, including the Merger, are in the best interest of ENLK and the ENLK Unaffiliated Unitholders, (ii) approved the Merger Agreement, the other Transaction Documents, and the Transactions, and directed that the Merger Agreement be submitted to a vote of the ENLK Voting Unitholders, and (iii) determined to recommend that the ENLK Voting Unitholders approve the Merger Agreement.

        Accordingly, each of the ENLK Conflicts Committee and the ENLK Board recommends that the ENLK Voting Unitholders vote "FOR" the ENLK Merger Proposal, and the ENLK Board recommends that the ENLK Voting Unitholders vote "FOR" the ENLK Adjournment Proposal.

Opinion of Evercore—Financial Advisor to the ENLK Conflicts Committee (see page 70)

        The ENLK Conflicts Committee retained Evercore Group L.L.C. ("Evercore") to act as its financial advisor in connection with evaluating the proposed Merger. At the request of the ENLK Conflicts Committee, at a meeting of the ENLK Conflicts Committee held on October 21, 2018, Evercore rendered its oral opinion to the ENLK Conflicts Committee (subsequently confirmed in writing) that, as of October 21, 2018 and based upon and subject to the assumptions made, procedures followed, matters considered, and qualifications and limitations of the review undertaken by Evercore in rendering its opinion as set forth therein, the Exchange Ratio was fair, from a financial point of view, to the ENLK Unaffiliated Unitholders.

        The full text of the written opinion of Evercore, which sets forth the assumptions made, procedures followed, matters considered, and qualifications and limitations of the review undertaken in rendering its opinion, is attached hereto as Annex G.

        The directors and executive officers of EGP and EMM have interests in the Merger that are or may be different from, or in addition to, the interests of the ENLK Unitholders and ENLC Unitholders generally. The members of the ENLK Board and ENLC Board were aware of and considered these interests, among other matters, in evaluating and negotiating the Merger Agreement and the Merger, and in recommending to the ENLK Voting Unitholders, that the ENLK Merger Proposal be approved and recommending to the ENLC Unitholders that the ENLC Unit Issuance be approved, as applicable. These interests include:

The Merger Agreement (see page 93)

        The Merger Agreement is attached to this joint information statement/proxy statement/prospectus as Annex A and is incorporated by reference into this joint information statement/proxy statement/prospectus. You should read carefully the Merger Agreement in its entirety because it, and not this joint information statement/proxy statement/prospectus, is the legal document that governs the terms of the Transactions, including the Merger. For more information, please read the section entitled "The Merger Agreement" beginning on page 93.

        Upon the terms and subject to the conditions set forth in the Merger Agreement and in accordance with Delaware law, Merger Sub will be merged with and into ENLK, with ENLK surviving as a subsidiary of ENLC (the "surviving entity").

        The Merger Agreement provides that, at the Effective Time, each ENLK Public Unit issued and outstanding immediately prior to the Effective Time will be converted into the right to receive 1.15 ENLC Common Units. No fractional ENLC Common Units will be issued in the Merger; instead, all fractional ENLC Common Units to which an ENLK Public Unitholder would otherwise be entitled will be aggregated and the resulting fraction will be rounded up to the nearest whole ENLC Common Unit.

        The Merger Agreement provides that, at the Effective Time, (i) all ENLK Series B Units issued and outstanding immediately prior to the Effective Time will, at the Effective Time, continue to be issued and outstanding and represent limited partner interests in the surviving entity, and the terms thereof will be amended as set forth in the Amended ENLK Partnership Agreement (as described and defined below in the section entitled "Preferred Restructuring Agreement—Amended ENLK Partnership Agreement"); and (ii) all ENLK Series C Units issued and outstanding immediately prior to the Effective Time will, at the Effective Time, continue to be issued and outstanding and represent limited partner interests in the surviving entity. No consideration will be delivered to the ENLK Series B Unitholders or the holders of ENLK Series C Units in respect thereof.

        The Merger Agreement provides that, at the Effective Time, (a) any ENLK Common Units that are owned immediately prior to the Effective Time by ENLK will automatically be cancelled and cease to exist, (b) all of the (i) ENLK Common Units owned immediately prior to the Effective Time by the ENLC Group and (ii) the general partner interest in ENLK owned immediately prior to the Effective Time by EGP, in each case, will be unaffected by the Merger and will remain outstanding in the surviving entity as set forth in the Amended ENLK Partnership Agreement, and such ENLK Common Units and general partner interest will continue to represent partnership interests in the surviving entity, and (c) the Incentive Distribution Rights will be cancelled and cease to exist.

        The Merger Agreement provides that, at the Effective time, each ENLK Equity Award will automatically be converted into the right to receive a comparable award with respect to ENLC Common Units, as more fully described in the section entitled "The Merger Agreement—Other Effects of the Merger—Treatment of ENLK Equity Awards."

        For more information regarding the effects of the Merger, see "The Merger Agreement—Merger Consideration" and "The Merger Agreement—Other Effects of the Merger."

        ENLC and ENLK currently expect to complete the Merger shortly following the conclusion of the ENLK Unitholder Meeting, subject to the receipt of the required ENLK Unitholder Approval and regulatory approvals and clearances and to the satisfaction or waiver of the other conditions to the Transactions described below.

        As more fully described in the section entitled "The Merger Agreement—Conditions to the Completion of the Merger," the parties' obligations to complete the Transactions depend on the satisfaction of a number of closing conditions (unless such closing conditions are waived, to the extent legally permissible), including the following:

Table of Contents

        The Merger Agreement may be terminated at any time prior to the Effective Time:

        The action by ENLK or ENLC to terminate the Merger Agreement is subject to certain requirements to refer such action to the ENLK Conflicts Committee or ENLC Conflicts Committee, as applicable, and provide such committee two business days to make a recommendation to the ENLK Board or ENLC Board, as applicable, which board is not obligated to follow such recommendation. For more information, please read "The Merger Agreement—Termination of the Merger Agreement."

        Following the termination of the Merger Agreement under specified circumstances further described in "The Merger Agreement—Termination Fee and Expense Reimbursement," ENLC may be required to pay the out-of-pocket costs and expenses incurred by EGP and ENLK in connection with the Merger Agreement or ENLK may be required to pay the out-of-pocket costs and expenses in connection with the Merger Agreement, in either case, up to a maximum of $5 million, or ENLK may be required to pay ENLC a termination fee of $55 million.

Material U.S. Federal Income Tax Consequences of the Merger (see page 167)

        The receipt of ENLC Common Units in exchange for ENLK Common Units pursuant to the Merger Agreement will be a taxable transaction for U.S. federal income tax purposes to U.S. Holders

Table of Contents

(as defined in the section titled "Material U.S. Federal Income Tax Consequences"). In such case, a U.S. Holder who receives ENLC Common Units in exchange for ENLK Common Units pursuant to the Merger Agreement will recognize ordinary income to the extent of the U.S. Holder's share of depreciation recapture, other "unrealized receivables," and "inventory items" owned by ENLK and its subsidiaries and capital gain or capital loss in an amount equal to the difference between:

        Capital gain recognized by an individual on the sale of common units held for more than twelve months will generally be taxed at the U.S. federal income tax rate applicable to long-term capital gains. A U.S. Holder's passive losses in respect of its ENLK Common Units that were not deductible by the U.S. Holder in prior taxable periods because they exceeded the U.S. Holder's share of ENLK's income may become available to offset a portion of the gain recognized by such U.S. Holder.

        The U.S. federal income tax consequences of the Merger to an ENLK Common Unitholder will depend on such unitholder's own personal tax situation. Accordingly, you are strongly urged to consult your tax advisor for a full understanding of the particular tax consequences of the Merger to you.

        See the section titled "Material U.S. Federal Income Tax Consequences" for a more complete discussion of U.S. federal income tax consequences of the Merger.

The Support Agreements (see page 113)

        Concurrently with the execution and delivery of the Merger Agreement, ENLC, GIP Stetson I, Acacia, and EMI entered into the ENLK Support Agreement with ENLK, pursuant to which GIP Stetson I, Acacia, and EMI, the Supporting Common Unitholders, agreed to, among other things and while the ENLK Support Agreement remains in effect, vote the 94,660,600 ENLK Common Units, 68,248,199 ENLK Common Units, and 20,280,252 ENLK Common Units (representing, in the aggregate, approximately 44.5% of the outstanding ENLK Voting Units) held of record and beneficially by each of the Supporting Common Unitholders, respectively, in favor of the approval of the ENLK Merger Proposal and, if necessary, the ENLK Adjournment Proposal.

        Additionally, concurrently with the execution of the Merger Agreement, the Enfield Parties and ENLK entered into the Enfield Support Agreement, pursuant to which, among other things and while the Enfield Support Agreement remains in effect, Enfield agreed to vote the ENLK Series B Units that it held as of such time and any additional ENLK Series B Units it acquired in favor of the approval of the ENLK Merger Proposal and, if necessary, the ENLK Adjournment Proposal. Enfield holds 58,728,994 ENLK Series B Units of record (representing approximately 14.3% of the outstanding ENLK Voting Units).

        Additionally, concurrently with the execution of the Merger Agreement, GIP Stetson II and ENLK entered into the GIP Support Agreement, pursuant to which GIP Stetson II agreed to, among other things, vote the 115,495,669 ENLC Common Units (representing approximately 63.7% of the outstanding ENLC Common Units) held of record and beneficially by GIP Stetson II in favor of the adoption of the ENLC Unit Issuance and any related matter that must be approved by the ENLC Unitholders in order for the Transactions, including the ENLC Unit Issuance, to be consummated. GIP Stetson II has executed and delivered the ENLC Written Consent. Pursuant to the GIP Support Agreement, GIP Stetson II agreed that it will not amend, modify, withdraw, terminate, or revoke the ENLC Written Consent.

10


Table of Contents

        The Supporting Voting Unitholders collectively own ENLK Voting Units representing approximately 58.8% of the outstanding ENLK Voting Units. As a result, the affirmative vote by the Supporting Voting Unitholders will be sufficient to approve the ENLK Merger Proposal and, if necessary, the ENLK Adjournment Proposal.

        For more information, please read "The Support Agreements."

Directors and Executive Officers of EMM Following the Merger (see page 120)

        ENLC expects that the directors and executive officers of EMM prior to the Merger will continue as directors and executive officers of EMM after the Merger. However, GIP Stetson I, the sole owner of EMM, is entitled to appoint all of the members of the ENLC Board in its sole discretion, and may determine to remove or replace any member of the ENLC Board, or appoint one or more additional members of the ENLC Board, in connection with the consummation of the Merger or otherwise. As of the date of this joint information statement/proxy statement/prospectus, GIP Stetson I has not taken any action under the Second Amended and Restated Limited Liability Company Agreement of EMM (the "EMM LLC Agreement") to effect any such changes to the composition of the ENLC Board. In addition, pursuant to the Preferred Restructuring Agreement and the Amended and Restated Board Representation Agreement to be entered into upon consummation of the Merger, Mr. Ortega or another designee of TPG will be appointed as a member of the ENLC Board.

No Dissenters' or Appraisal Rights (see page 86)

        Under the Delaware LP Act and the ENLK Partnership Agreement, there are no dissenters' or appraisal rights for the ENLK Unitholders with respect to the Transactions.

Required Regulatory Approvals (see page 86)

        In order to consummate the Transactions, a filing must be made under the HSR Act and the rules promulgated thereunder by the FTC, and the waiting period, and any extension thereof, must have expired or been terminated. During the waiting period, and any extension thereof, the FTC and the DOJ may request additional information or take such action under the antitrust laws as the agencies deem necessary or desirable in the public interest, including seeking to enjoin the completion of the Transactions. ENLK and GIP Stetson II filed the requisite HSR Act notification forms on November 2, 2018, and early termination of the waiting period was granted on November 14, 2018. There are no other federal or state regulatory requirements that must be complied with or approvals that must be obtained in connection with the Transactions.

Accounting Treatment (see page 86)

        The Merger will be accounted for in accordance with Financial Accounting Standards Board Accounting Standards Codification 810, Consolidation. As ENLC controls ENLK and will continue to control ENLK after the Merger, the changes in ENLC's ownership interests in ENLK will be accounted for as an equity transaction and no gain or loss on the Merger will be recognized in ENLC's consolidated statements of operations.

Listing of ENLC Common Units to be Issued in the Merger; Delisting and Deregistration of ENLK Common Units (see page 86)

        ENLC expects to obtain approval to list on the NYSE the ENLC Common Units to be issued pursuant to the Merger Agreement, which approval (subject to official notice of issuance) is a condition to closing the Merger. Upon completion of the Merger, ENLK Common Units currently listed on the NYSE will cease to be listed on the NYSE and will be subsequently deregistered under the Exchange Act.

RISK FACTORS

        You should consider carefully the following risk factors, together with all of the other information included in, or incorporated by reference into, this joint information statement/proxy statement/prospectus before deciding how to vote. In particular, please read Part I, Item 1A, "Risk Factors," in the Annual Reports on Form 10-K for the year ended December 31, 2017 for each of ENLC and ENLK, in each case, as updated by subsequent Quarterly Reports on Form 10-Q, all of which are incorporated by reference herein. This document also contains forward-looking statements that involve risks and uncertainties. Please read "Cautionary Statement Regarding Forward-Looking Statements."

Risks Related to the Transactions

Because the Exchange Ratio is fixed and because the market price of ENLC Common Units will fluctuate prior to the completion of the Merger, ENLK Public Unitholders cannot be sure of the market value of the ENLC Common Units they will receive as merger consideration relative to the value of ENLK Common Units they exchange.

        The market value of the consideration that ENLK Public Unitholders will receive in the Merger will depend on the trading price of ENLC Common Units at the closing of the Merger. The Exchange Ratio that determines the number of ENLC Common Units that ENLK Public Unitholders will receive in the Merger is fixed at 1.15 ENLC Common Units for each ENLK Common Unit. This means that there is no mechanism contained in the Merger Agreement that would adjust the number of ENLC Common Units that ENLK Public Unitholders will receive based on any decreases or increases in the trading price of ENLC Common Units or the ENLK Common Units. The potential diminution in value experienced by ENLK Public Unitholders in the Merger could be substantial. Unit price changes may result from a variety of factors (many of which are beyond ENLC's and ENLK's control), including:

        If the price of ENLC Common Units at the closing of the Merger is less than the price of ENLC Common Units on the days leading up to the signing of the Merger Agreement, then the market value of the merger consideration will be less than contemplated at the time the Merger Agreement was signed.

        In addition, the ENLK Public Unitholders will receive as Merger Consideration ENLC Common Units that are expected to receive, in the near term, lower distributions per unit, after giving effect to the Exchange Ratio, as compared to each ENLK Common Unit if the Merger were not consummated.

Under certain specified circumstances, ENLK may be responsible for ENLC's expenses or paying to ENLC a termination fee or ENLC may be required to pay ENLK's expenses.

        If the Merger Agreement is terminated (i) by ENLC due to a material uncured breach by EGP or ENLK of their respective representations, warranties, covenants, or agreements under the Merger Agreement, or (ii) by ENLC or ENLK due to a failure to obtain the ENLK Unitholder Approval when, prior to the ENLK Unitholder Meeting, a recommendation change occurred, ENLK will reimburse to ENLC certain expenses of the ENLC Group up to $5 million. In addition, if the Merger

21


Table of Contents

Agreement is terminated (a) by ENLC following a recommendation change by the ENLK Board or the ENLK Conflicts Committee or (b) by ENLK as a result of receipt of a superior proposal, ENLK will be required to pay to ENLC a termination fee in cash in an amount equal to $55 million. See "The Merger Agreement—Termination Fee and Expense Reimbursement."

        If the Merger Agreement is terminated by ENLK due to a material uncured breach by EMM, ENLC, or Merger Sub of their respective representations, warranties, covenants, or agreements under the Merger Agreement, ENLC will reimburse to ENLK certain expenses of the ENLK Group up to $5 million.

ENLK is subject to provisions in the Merger Agreement that limit its ability to pursue alternatives to the Merger and that could discourage a potential competing acquirer from making a favorable alternative transaction proposal.

        Under the Merger Agreement, ENLK is restricted from pursuing acquisition proposals (as further described in "The Merger Agreement—No Solicitation by ENLK of Acquisition Proposals"). Under certain "no-shop" covenants, subject to certain exceptions, EGP has agreed that it will not, and will cause ENLK and its subsidiaries not to, and to use their respective reasonable best efforts to cause EGP's, ENLK's, and ENLK's subsidiaries directors, officers, employees, counsel, investment bankers, financial advisors, and other representatives not to, directly or indirectly:

        Subject to certain exceptions, EGP has also agreed to, and to cause ENLK and its subsidiaries to, and to use its reasonable best efforts to cause EGP's, ENLK's, and ENLK's subsidiaries' directors, officers, employees, counsel, investment bankers, financial advisors, and other representatives to, (a) immediately cease and cause to be terminated any discussions or negotiations with any persons conducted prior to the execution of the Merger Agreement regarding an acquisition proposal, and (b) immediately prohibit any access by any persons to any confidential information relating to an acquisition proposal.

        In addition, ENLK has agreed not to make a recommendation change except in accordance with the Merger Agreement. Under the Merger Agreement, in the event of a potential recommendation change (as described under "The Merger Agreement—EGP Recommendation and EGP

22


Table of Contents

Recommendation Change"), the ENLK Board or the ENLK Conflicts Committee (as applicable) must provide ENLC with four days' notice to allow ENLC to propose an adjustment to the terms and conditions of the Merger.

        Further, as described above, under certain circumstances, ENLK will be required to pay ENLC a termination fee of $55 million. See "The Merger Agreement—Termination Fee and Expense Reimbursement."

        These provisions could discourage a third party that may have an interest in acquiring all or a significant part of ENLK from considering or proposing that acquisition.

Financial projections by EnLink may not prove accurate and unaudited pro forma financial statements included in this joint information statement/proxy statement/prospectus are presented for illustrative purposes only. Such projections and unaudited pro forma financial statements may not be an indication of ENLC's financial condition or results of operations following the Transactions. Any potential decline in the financial condition or results of operations of ENLC may cause significant variations in the price of ENLC Common Units and/or could have a material adverse effect on the price of ENLC Common Units and ENLC's ability to make distributions following the completion of the Transactions.

        In performing their financial analyses and rendering their respective fairness opinions, the respective financial advisors to the ENLK Conflicts Committee and the ENLC Conflicts Committee reviewed and relied on, among other things, internal financial analyses and forecasts for ENLC and ENLK, which were prepared by EnLink management. These financial projections include, among others, assumptions regarding future operating cash flows, capital expenditures, and the growth and timing of distributions. These financial projections were not prepared with a view to public disclosure, are subject to significant economic, competitive, industry, and other uncertainties, and may not be achieved in full, at all, or within projected timeframes. The failure of ENLK's or ENLC's businesses to achieve projected results, including projected cash flows, could have a material adverse effect on the price of ENLC Common Units, ENLC's financial position and ENLC's ability to maintain or increase its distributions following the completion of the Transactions. See "The Merger—Unaudited Projected Financial Information."

        In addition, the unaudited pro forma financial statements contained in this joint information statement/proxy statement/prospectus were not provided with a view to public disclosure, are subject to significant economic, competitive, industry, and other uncertainties, and may not be achieved in full, at all or within projected timeframes. The actual financial condition and results of operations of ENLC following the Merger may not be consistent with, or evident from, these pro forma financial statements. The assumptions used in preparing the pro forma financial information may not prove to be accurate, and other factors may affect the financial condition or results of operations of ENLC following the Transactions. Any potential decline in the financial condition or results of operations of ENLC could have a material adverse effect on the price of ENLC Common Units and ENLC's ability to make distributions following the completion of the Transactions.

        See "Unaudited Pro Forma Condensed Combined Financial Statements."

The Transactions are subject to conditions, including some conditions that may not be satisfied on a timely basis, if at all, and the Merger Agreement contains certain termination rights for both ENLK and ENLC. Failure to complete Transactions, or significant delays in completing the Transactions, could negatively affect EnLink's future business and financial results and the trading prices of ENLC Common Units and ENLK Common Units.

        The Transactions are subject to the satisfaction or waiver of certain conditions, including the approval of the Merger Agreement by the holders of a majority of the ENLK Voting Units. The Merger Agreement contains other conditions that, if not satisfied or waived, would result in the

23


Table of Contents

Transactions not occurring, even though the ENLK Voting Unitholders may have approved the Merger Agreement. Satisfaction of some of these other conditions to the Transactions is not entirely in the control of ENLK or ENLC. The closing conditions to the Transactions may not be satisfied, and ENLK and ENLC may choose not to, or may be unable to, waive an unsatisfied condition, which may cause the Transactions not to occur. See "The Merger Agreement—Conditions to Completion of the Merger."

        The Merger Agreement also contains certain termination rights for both ENLK and ENLC, including, among others, (i) by the mutual written agreement of ENLK (duly authorized by the ENLK Conflicts Committee) and ENLC (duly authorized by the ENLC Board); (ii) by either ENLK or ENLC, if (A) the Merger has not been consummated on or before June 30, 2019; (B) a governmental authority has issued a non-appealable order, decree, or ruling or taken any other action (including the enactment of any law) permanently restraining, enjoining, or otherwise prohibiting the Transactions (provided that the party seeking to terminate the Merger Agreement on this basis must have complied with its obligations with respect to the holding of the ENLK Unitholder Meeting, the recommendation of the ENLK Board, the use of reasonable best efforts to cause the consummation of the Transactions, and cooperation to obtain required regulatory approvals); or (C) the requisite approval of the Merger Agreement is not obtained; (iii) by ENLC, if (A) the ENLK Board (upon the recommendation of the ENLK Conflicts Committee) or the ENLK Conflicts Committee makes a recommendation change (as described herein) prior to the ENLK Unitholder Meeting or (B) if under certain conditions, there has been a material breach by ENLK of any of its representations, warranties, or covenants set forth in the Merger Agreement that is not cured within 30 days of notice of such breach; and (iv) by ENLK, if (A) subject to certain conditions, ENLK has received a superior proposal (as defined below) and the ENLK Board (upon recommendation of the ENLK Conflicts Committee) or the ENLK Conflicts Committee has determined in good faith that the failure to terminate the Merger Agreement would be inconsistent with their respective fiduciary duties, or (B) under certain conditions, there has been a material breach by ENLC of any of its representations, warranties, or covenants set forth in the Merger Agreement that is not cured within 30 days of notice of such breach. See "The Merger Agreement—Termination of the Merger Agreement."

        If the Transactions are not completed, or if there are significant delays in completing the Transactions, EnLink's business and financial results and the trading prices of ENLC Common Units and ENLK Common Units could be negatively affected, and each of the parties will be subject to several risks, including the following:

Maintaining credit ratings is under the control of ratings agencies, which are independent third parties. There can be no assurances that EnLink's credit ratings will be affirmed following the consummation of the Transactions, and changes to EnLink's credit ratings could negatively impact ENLC's access to capital and costs of doing business.

        In connection with the completion of the Merger, ratings agencies may reevaluate ENLC's and ENLK's credit ratings. Credit rating agencies perform independent analyses when assigning credit ratings and there can be no assurances that EnLink's credit ratings will be affirmed following the

24


Table of Contents

consummation of the Transactions or maintained in the future. The analyses include a number of criteria including, but not limited to, business composition, market, and operational risks, as well as various financial tests. Pro Forma ENLC's ratings upon completion of the Merger will reflect each rating organization's opinion of Pro Forma ENLC's financial strength, operating performance, and ability to meet the obligations associated with its securities. In addition, the trading market for ENLC's and ENLK's securities depends, in part, on the research and reports that third-party securities analysts publish about ENLC and ENLK and the industry in which they participate. In connection with the completion of the Merger, one or more of these analysts could downgrade ENLC or ENLK securities or issue other negative commentary about ENLC and ENLK and the industry in which they participate, which could cause the trading price of such securities to decline.

        The failure of EnLink's credit ratings to be affirmed following the consummation of the Transactions or a downgrade may increase ENLC's and ENLK's cost of borrowing, may negatively impact ENLC's and ENLK's ability to raise additional debt capital, may negatively impact ENLC's and ENLK's ability to successfully compete, and may negatively impact the willingness of counterparties to deal with ENLC and ENLK, each of which could have a material adverse effect on the business, financial condition, results of operations and cash flows of ENLC and ENLK, as well as the market price of their respective securities.

        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 Pro Forma ENLC will be subject to ongoing evaluation by credit rating agencies, and downgrades in Pro Forma ENLC's ratings could adversely affect Pro Forma ENLC's business, cash flows, financial condition, operating results, and equity and debt prices.

ENLK and ENLC 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 Transactions.

        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 such parties. Even though we believe any such lawsuits are without merit, defending against these claims can result in substantial costs and divert management time and resources. ENLK and ENLC 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 Transactions could delay or prevent their consummation. In addition, the costs of defending the litigation, even if resolved in ENLK's or ENLC's favor, could be substantial and such litigation could distract ENLK and ENLC from pursuing the consummation of the Transactions and other potentially beneficial business opportunities.

The date ENLK Public Unitholders will receive the merger consideration depends on the completion date of the Merger, which is uncertain.

        As described in this joint information statement/proxy statement/prospectus, completing the proposed merger is subject to several conditions, not all of which are controllable or waivable by ENLC or ENLK. Accordingly, even if the proposed Merger is approved by ENLK Voting Unitholders, the date on which ENLK Public Unitholders will receive merger consideration depends on the completion date of the Merger, which is uncertain and subject to several other closing conditions.

25


Table of Contents

If the Merger does not occur, ENLC and ENLK will not benefit from the expenses they have incurred in the pursuit of the Merger.

        The Merger may not be completed. If the Merger is not completed, each of ENLC and ENLK will have incurred substantial expenses for which no ultimate benefit will have been received by it. ENLC and ENLK currently expect to incur several million dollars with respect to merger-related expenses, consisting of independent advisory, legal, and accounting fees, and financial printing and other related charges, much of which may be incurred even if the Merger is not completed.

Directors and executive officers of EMM and EGP have certain interests that are different from those of the ENLC Unitholders and ENLK Unitholders generally.

        Directors and executive officers of EMM and EGP 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 an ENLC Unitholder or ENLK Unitholder, as applicable. In addition, certain of the directors and executive officers of EGP are also directors or executive officers at EMM. These and other different interests are described under "Certain Relationships; Interests of Certain Persons in the Merger." ENLK Voting Unitholders should consider these interests in voting on the ENLK Merger Proposal and/or the ENLK Adjournment Proposal.

The opinions rendered to the ENLC Conflicts Committee and the ENLK Conflicts Committee by their respective financial advisors on October 21, 2018, were based on the financial analysis performed by the applicable financial advisor, which were based on information made available to the financial advisor, as of the date of its opinion and financial, economic, monetary, market, regulatory, and other conditions as they existed and as could be evaluated on the date thereof. As a result, these opinions do not reflect changes in events or circumstances after the date of the opinions. The ENLC Conflicts Committee and ENLK Conflicts Committee have not requested, and do not expect to request, updated opinions from their respective financial advisors reflecting changes in circumstances that may have occurred since the signing of the Merger Agreement.

        The opinions rendered to the ENLC Conflicts Committee and the ENLK Conflicts Committee by Barclays and Evercore, respectively, were provided in connection with, and at the time of, the evaluation of the Transactions and the Transaction Documents by the ENLC Conflicts Committee and the ENLK Conflicts Committee. These opinions were based on the financial analysis performed by Barclays and Evercore, respectively, which were based on information made available to Barclays and Evercore, respectively, as of the date of their opinions and financial, economic, monetary, market, regulatory, and other conditions as they existed and as could be evaluated on the date thereof, which may have changed, or may change, after the date of the opinions. The ENLC Conflicts Committee and the ENLK Conflicts Committee have not requested updated opinions as of the date of this joint information statement/proxy statement/prospectus from their respective financial advisors, and they do not expect to request updated opinions prior to completion of the Transactions. Changes in the operations and prospects of ENLC or ENLK, general market and economic conditions, and other factors which may be beyond the control of ENLC or ENLK, and on which the opinions were based, may have altered the value of ENLC or ENLK or the prices of ENLC Common Units or ENLK Common Units since the date of such opinions, or may alter such values and prices by the time the Transactions are completed. The opinions do not speak as of any date other than the date of the applicable opinion.

        For a description of the opinion that the ENLC Conflicts Committee received from Barclays, please refer to "Opinion of Barclays—Financial Advisor to the ENLC Conflicts Committee." For a description of the opinion that the ENLK Conflicts Committee received from Evercore, please refer to "Opinion of Evercore—Financial Advisor to the ENLK Conflicts Committee."

Tax Risks Related to the Merger and the Ownership of ENLC Common Units

The Merger will be a taxable transaction to ENLK Common Unitholders and, in such case, the resulting tax liability of an ENLK Common Unitholder, if any, will depend on the unitholder's particular situation. ENLK Common Unitholders will receive no cash consideration with which to pay any potential U.S. federal income tax liability resulting from the Merger.

        ENLK Common Unitholders will receive solely ENLC Common Units as the Merger Consideration. Although ENLK Common Unitholders will receive no cash consideration, the Merger will be treated as a taxable sale by U.S. Holders (as defined in the section titled "Material U.S. Federal Income Tax Consequences") of ENLK Common Units for U.S. federal income tax purposes. As a result, a U.S. Holder will generally recognize (i) ordinary income to the extent of the U.S. Holder's share of depreciation recapture, other "unrealized receivables," and "inventory items" owned by ENLK and its subsidiaries and (ii) capital gain or capital loss equal to the difference between the U.S. Holder's amount realized and the sum of the U.S. Holder's tax basis in its ENLK Common Units and the amount of ordinary income recognized by the U.S. Holder as described in clause (i). The amount of ordinary income and capital gain or loss recognized by each ENLK Common Unitholder in the Merger will vary depending on each unitholder's particular situation, including the value of the ENLC Common Units received by each unitholder in the Merger, the amount of depreciation and amortization deductions previously passed-through from ENLK to the unitholder, the adjusted tax basis of the ENLK Common Units exchanged by each unitholder in the Merger, and the amount of any suspended passive losses that may be available to a particular unitholder to offset a portion of the gain recognized by the unitholder.

        For a more complete discussion of material U.S. federal income tax consequences of the Merger, see the section titled "Material U.S. Federal Income Tax Consequences."

The tax liability of an ENLK Common Unitholder as a result of the Merger could be more than expected.

        Because the fair market value of any ENLC Common Unit received in the Merger will not be known until the Effective Time, an ENLK Common Unitholder will not be able to determine its amount realized, and therefore its taxable gain or loss, until such time. In addition, because prior distributions in excess of an ENLK Common Unitholder's allocable share of ENLK's net taxable income decrease the unitholder's tax basis in its ENLK Common Units, the amount, if any, of the prior excess distributions with respect to such common units will, in effect, become taxable income to a unitholder if the aggregate value of the consideration received in the Merger is greater than the unitholder's adjusted tax basis in its ENLK Common Units, even if the aggregate value of the consideration received in the Merger is less than the unitholder's original cost basis in its ENLK Common Units. Furthermore, a portion of this gain or loss, which could be substantial, will be separately computed and taxed as ordinary income or loss to the extent attributable to depreciation recapture, other "unrealized receivables," or "inventory items" owned by ENLK and its subsidiaries.

        For a more complete discussion of material U.S. federal income tax consequences of the Merger, see the section titled "Material U.S. Federal Income Tax Consequences."

The U.S. federal income tax treatment of owning and disposing of ENLC Common Units received in the Merger will be different than the U.S. federal income tax treatment of owning and disposing of the ENLK Common Units surrendered in the Merger.

        ENLK is classified as a partnership for U.S. federal income tax purposes and, generally, is not subject to entity-level U.S. federal income taxes. Instead, each ENLK Common Unitholder is required to take into account its respective share of ENLK's items of income, gain, loss, and deduction in computing its federal income tax liability, even if no cash distributions are made by ENLK to the unitholder. A pro rata distribution of cash by ENLK to an ENLK Common Unitholder who is a U.S.

Table of Contents

Holder (as defined in the section titled "Material U.S. Federal Income Tax Consequences") is generally not taxable for U.S. federal income tax purposes unless the amount of cash distributed is in excess of the unitholder's adjusted tax basis in its ENLK Common Units.

        In contrast, ENLC is classified as a corporation for U.S. federal income tax purposes and is subject to U.S. federal income tax on its taxable income. A distribution of cash by ENLC to an ENLC Unitholder who is a U.S. Holder will generally be included in such unitholder's income as ordinary dividend income to the extent of ENLC's current or accumulated "earnings and profits," as determined under U.S. federal income tax principles. A portion of the cash distributed to ENLC Unitholders by ENLC after the Merger may exceed ENLC's current and accumulated earnings and profits. Cash distributions to an ENLC Unitholder who is a U.S. Holder in excess of ENLC's current and accumulated earnings and profits will be treated as a non-taxable return of capital, reducing the adjusted tax basis in the holder's ENLC Common Units and, to the extent the cash distribution exceeds the holder's adjusted tax basis, as capital gain from the sale or exchange of such ENLC Common Units.

        For a more complete discussion of material U.S. federal income tax consequences of the Merger, see the section titled "Material U.S. Federal Income Tax Consequences."

ENLC's ability to use net operating losses ("NOLs") to offset future income may be limited.

        As of December 31, 2017, ENLC had approximately $225 million of U.S. federal net operating loss carryforwards ("NOLs"), which expire beginning in 2034. NOLs generated after December 31, 2017 do not expire. Utilization of these NOLs depends on many factors, including ENLC's future income, which cannot be assured. In addition, Section 382 of the Internal Revenue Code of 1986, as amended ("Section 382"), generally imposes an annual limitation on the amount of NOLs that may be used to offset taxable income by a corporation that has undergone an "ownership change" (as determined under Section 382). In general, an "ownership change" occurs if ENLC's "5-percent shareholders," as defined under Section 382 of the Code, including certain groups of persons treated as "5-percent shareholders," collectively increased their ownership in ENLC Common Units by more than 50 percentage points over their lowest ownership during a rolling three-year period. An ownership change can occur as a result of a public offering of ENLC Common Units, as well as through secondary market purchases of ENLC Common Units and certain types of reorganization transactions. As a result of the exchange of ENLK Common Units for ENLC Common Units in the Merger, ENLC expects that the Merger will cause ENLC to experience an ownership change and, thus, that ENLC's ability to offset future taxable income with its pre-ownership change NOLs will be subject to limitation under Section 382. Such a limitation could, for any given year, have the effect of increasing the amount of ENLC's U.S. federal income tax liability, which would negatively impact the amount of after-tax cash available for distribution to ENLC Unitholders and ENLC's financial condition.

        For a more complete discussion of material U.S. federal income tax consequences of the Merger, see the section titled "Material U.S. Federal Income Tax Consequences."

ENLC's future tax liability may be greater than expected if it does not generate NOLs sufficient to offset taxable income or if tax authorities challenge certain of its tax positions.

        ENLC expects to generate deductions and NOL carryforwards that it can use to offset taxable income. As a result, ENLC does not expect to pay meaningful U.S. federal income tax through at least 2023. This estimate is based upon assumptions ENLC has made regarding, among other things, income, capital expenditures, and net working capital. Further, the Internal Revenue Service (the "IRS") or other tax authorities could challenge one or more tax positions ENLC takes, such as the classification of assets under the income tax depreciation rules, the characterization of expenses for income tax purposes, and the tax classification of the Merger. Further, any change in law may affect ENLC's tax position. While ENLC expects that its deductions and NOL carryforwards will be available to it as a

future benefit, in the event that they are not generated as expected, are successfully challenged by the IRS (in a tax audit or otherwise), or are subject to future limitations as described below, ENLC's ability to realize these benefits may be limited.

        For a more complete discussion of material U.S. federal income tax consequences of the Merger, see the section titled "Material U.S. Federal Income Tax Consequences."

The recently passed comprehensive tax reform bill could adversely affect ENLC's business and financial condition.

        On December 22, 2017, tax legislation commonly known as the Tax Cuts and Jobs Act ("Tax Cuts and Jobs Act") was enacted. Among other things, the Tax Cuts and Jobs Act (i) reduces the U.S. corporate income tax rate from 35% to 21% (beginning in 2018), (ii) generally will limit ENLC's annual deductions for interest expense to no more than 30% of ENLC's "adjusted taxable income" (plus 100% of ENLC's business interest income) for the year, and (iii) will permit ENLC to offset only 80% (rather than 100%) of ENLC's taxable income with any NOLs ENLC generates after 2017. Currently ENLC does not expect the provisions of the Tax Cuts and Jobs Act, taken as a whole, to have any material adverse impact on ENLC's cash tax liabilities, financial condition, results of operations, or cash flows. However, it is possible in the future that the NOL and/or interest deductibility limitations could have the effect of causing ENLC to incur income tax liability sooner than ENLC otherwise would have incurred such liability or, in certain cases, could cause ENLC to incur income tax liability that ENLC might otherwise not have incurred, in the absence of these tax law changes.

THE MERGER

        This discussion of the Merger is qualified in its entirety by reference to the Merger Agreement, a copy of which is attached to this joint information statement/proxy statement/prospectus as Annex A and incorporated into this joint information statement/proxy statement/prospectus by reference. You should read carefully the Merger Agreement in its entirety because it, and not this joint information statement/proxy statement/prospectus, is the legal document that governs the terms of the Transactions, including the Merger.

Effects of the Merger

        On October 21, 2018, ENLC, ENLK, Merger Sub, EGP, and EMM (ENLC, EMM, ENLK, and EGP collectively referred to as the "EnLink Parties") entered into the Merger Agreement, pursuant to which Merger Sub, subject to the satisfaction or waiver of certain conditions in the Merger Agreement, will merge with and into ENLK, with ENLK surviving the Merger as a subsidiary of ENLC (referred to in this summary with respect to periods following the Effective Time, interchangeably, as "ENLK" or the "surviving entity"), and each outstanding ENLK Public Unit will be converted into the right to receive 1.15 ENLC Common Units.

        Concurrently with the entry into the Merger Agreement, in connection with the Preferred Restructuring Agreement, Enfield and the EnLink Parties agreed that (i) each ENLK Series B Unit issued and outstanding immediately prior to the Effective Time shall, at the Effective Time, continue to be issued and outstanding and represent a limited partner interest in ENLK, with terms and conditions modified in accordance with the Amended ENLK Partnership Agreement, including exchangeability of the ENLK Series B Units, under certain conditions, into ENLC Common Units instead of ENLK Common Units, subject to the election of ENLK to instead redeem for cash any such exchanged ENLK Series B Units, and no additional consideration will be delivered to any ENLK Series B Unitholder in respect of the Merger and the Preferred Restructuring Agreement and (ii) ENLC will issue to Enfield, for no additional consideration, a new class of non-economic common units representing limited liability company interests in ENLC (the "ENLC Class C Common Units") equal to the number of ENLK Series B Units held by Enfield immediately following the Effective Time in order to provide Enfield with certain voting rights at ENLC in accordance with the Amended ENLC Operating Agreement.

        Once the Merger is completed, former ENLK Public Unitholders who surrender their ENLK Public Units in accordance with the Merger Agreement will be eligible, in their capacity as ENLC Unitholders, to receive distributions on the ENLC Common Units declared by the ENLC Board, if any, with a record date after the Effective Time. For additional discussion of the eligibility of ENLK Unitholders to receive distributions on ENLC Common Units, please read "The Merger Agreement—Distributions." For a description of ENLK's distribution policy, please read "Comparison of the Rights of ENLC Unitholders and ENLK Unitholders."

        Based upon the 264,572,534 ENLK Public Units outstanding on October 21, 2018 and 1,141,062 ENLK Common Units that ENLK anticipates issuing with respect to ENLK Equity Awards which may vest prior to the Effective Time pursuant to the terms of the applicable award agreements, ENLC expects to issue approximately 305,570,636 ENLC Common Units in connection with the Merger. This number of ENLC Common Units will represent approximately 62.9% of the outstanding ENLC Common Units as of October 21, 2018. In connection with the closing of the Merger, the IDRs issued and outstanding immediately prior to the Effective Time and held by EGP will be cancelled and cease to exist. EGP will receive no consideration with respect to this cancellation of the IDRs. In addition, based upon the 58,728,994 ENLK Series B Units held by Enfield as of the date of this joint information statement/proxy statement/prospectus, ENLC expects to issue approximately 58,728,994 ENLC Class C Common Units at the Effective Time.

Background of the Merger

        The ENLC Board and the ENLK Board (collectively, the "EnLink Boards"), together with EnLink management, regularly review and assess operational and strategic opportunities to increase value for their respective investors and achieve long-term strategic goals. These reviews have included, among other things, potential opportunities for acquisitions and business combinations, capital projects, improvements to cost structure, operational improvements, capital raises, and other strategic alternatives. As more fully described in the section entitled "Certain Relationships; Interests of Certain Persons in the Merger," ENLC and ENLK are effectively under common control. However, each of the ENLC Board and the ENLK Board has also independently discussed various alternatives that could potentially complement, enhance, or improve both the strengths and strategic positions of ENLC and ENLK.

        In early 2017, EnLink management began specifically considering possible reorganization transactions involving ENLC, ENLK, and their subsidiaries to streamline and simplify the organizational structures of ENLC and ENLK, improve their cost of capital, and facilitate financing of growth opportunities, including, but not limited to, (i) the restructuring or elimination through various means of the incentive distribution rights (the "IDRs") of ENLK, which IDRs are held by EGP (an "IDR Restructuring"), (ii) a transaction pursuant to which ENLC would acquire all of the ENLK Common Units that are not already owned by ENLC or its subsidiaries (an "ENLC Simplification"), and (iii) a transaction pursuant to which ENLK would acquire all of the outstanding ENLC Common Units (an "ENLK Acquisition"), and, together with an ENLC Simplification and an IDR Restructuring, the "Restructuring Alternatives").

        In April 2017, EnLink management discussed possible Restructuring Alternatives with representatives of Citigroup Global Markets Inc. ("Citi"). These discussions focused particularly on an ENLC Simplification and an ENLK Acquisition. Representatives of Citi provided to EnLink management materials and information regarding precedent simplification transactions and general trends in the MLP industry.

        Also in April 2017, EnLink management met with representatives of Citi to discuss a potential strategic transaction involving EnLink and a third party ("Company A"). On April 24, 2017, EnLink management met with management of Company A to briefly discuss their mutual interest in a possible strategic combination between EnLink and Company A, including a merger of equals. Following this meeting, management of EnLink and Company A agreed to continue discussions regarding a potential transaction. On April 28, 2017, management of EnLink and Company A held a telephone conference and discussed an overview of a potential transaction, including potential synergies, organizational structure, and key issues for each company's owners and stakeholders. On April 29, 2017, management of EnLink and Devon, which, prior to July 18, 2018, held all of the membership interests in EMM and held ENLC Common Units representing approximately 63.7% of the outstanding ENLC Common Units, participated on a telephone conference to discuss the potential transaction. On this call, EnLink

management described the discussions and meetings that had been held as of such time with Company A.

        In May 2017, EnLink management continued discussing certain Restructuring Alternatives with Citi, focusing specifically on an ENLC Simplification. EnLink management held multiple discussions with management of Devon in May 2017 regarding the several Restructuring Alternatives.

        Between May 2017 and August 2017, EnLink management continued to evaluate the potential transaction with Company A, including through conversations with management of Company A, meetings with the EnLink Boards, and discussions with management of Devon.

        In July 2017, EnLink and Devon executed a confidentiality agreement with Company A, and the parties exchanged diligence materials in connection with a potential transaction. However, in August 2017, given, among other things, the overall energy markets, the uncertainty of commodity prices, midstream activity levels, and the valuation of the respective parties, management of EnLink and Company A mutually determined that they were not interested in pursuing a potential transaction at such time. Consistent with past practice, EnLink management informed and updated the EnLink Boards and Devon management regarding its discussions and the termination of such discussions with Company A and other representatives.

        From August 2017 to November 2017, EnLink management continued to evaluate Restructuring Alternatives and met with several financial advisors and management of Devon to discuss the midstream market and the viability of the Restructuring Alternatives. In August and September 2017, these meetings involved both an ENLC Simplification and an IDR Restructuring. In October and November 2017, these discussions centered primarily on an ENLC Simplification.

        In November 2017, ENLC engaged Baker Botts L.L.P. (EnLink's outside legal counsel) ("Baker Botts") to assist with the evaluation of the legal implications of an ENLC Simplification. Throughout November and early December 2017, EnLink management continued to discuss the possibility of an ENLC Simplification, including at regularly scheduled executive team meetings with Devon management and in discussions with Citi.

        On December 8, 2017, the EnLink Boards held a joint meeting to discuss the Restructuring Alternatives. At such meeting, EnLink management addressed the implications of an ENLC Simplification and an ENLK Acquisition, including possible acquisition scenarios and benefits involved in eliminating one of the two public companies maintained by EnLink. At this meeting, the EnLink Boards discussed the potential conflicts of interest that could arise between ENLC and ENLK in any possible Restructuring Alternative, regardless of the ultimate structure of such a transaction, and EnLink management suggested that the EnLink Boards consider delegating certain authority to the existing ENLC Conflicts Committee and ENLK Conflicts Committee. At such meeting, the ENLC Board authorized the ENLC Conflicts Committee, and the ENLK Board authorized the ENLK Conflicts Committee, to engage legal counsel and financial advisors in connection with the evaluation of a potential transaction involving one or more of the Restructuring Alternatives. Following this meeting, EnLink management held several internal meetings in December 2017 to discuss the viability of the various Restructuring Alternatives and the process of pursuing a potential transaction.

        In December 2017, the ENLK Conflicts Committee engaged Morris Nichols Arsht & Tunnell ("MNAT") to act as its counsel in connection with a potential transaction. Also in December 2017, the ENLC Conflicts Committee engaged Richards, Layton & Finger, P.A. ("RLF") to act as its counsel in connection with a potential transaction.

        On December 27, 2017, the ENLC Conflicts Committee held a telephonic meeting with a representative of RLF. The ENLC Conflicts Committee discussed the process of selecting a financial advisor to assist in evaluating the merits of the potential transaction from the perspective of ENLC and the holders of ENLC Public Units. The ENLC Conflicts Committee also discussed materials provided

at the request of the ENLC Conflicts Committee to the ENLC Conflicts Committee by three prospective financial advisors summarizing each advisor's prior relationships and engagements with ENLC, ENLK, and Devon.

        On January 3, 2018, EnLink, Baker Botts, and MNAT held a conference call to discuss the role of MNAT and general principles relating to a possible transaction.

        On January 8, 2018, the ENLC Conflicts Committee held an in-person meeting with representatives of RLF to discuss the potential transaction and interview potential financial advisors for the ENLC Conflicts Committee. The ENLC Conflicts Committee received a presentation from RLF regarding the duties and obligations of the ENLC Conflicts Committee in connection with the potential transaction. The ENLC Conflicts Committee separately interviewed representatives of three potential financial advisors. Throughout the interviews and the meeting, the ENLC Conflicts Committee discussed each advisor's knowledge of precedent simplification transactions, experience with conflicts committee assignments, relationships with ENLC, ENLK and Devon, and proposed fees for its work.

        On January 10, 2018, the ENLC Conflicts Committee held a telephonic meeting with representatives of RLF. The ENLC Conflicts Committee discussed the recent interviews with potential financial advisors and evaluated the relative strengths of the potential financial advisors and the independence of each advisor. The ENLC Conflicts Committee unanimously determined that Barclays had the requisite expertise to provide high quality advice to the ENLC Conflicts Committee and determined to engage Barclays as its financial advisor, subject to negotiation of a mutually acceptable fee and engagement letter. The ENLC Conflicts Committee determined to wait to inform Barclays until the timing of a potential transaction was more clear.

        In December 2017, Devon informed EnLink management, and on January 12, 2018, Devon informed the EnLink Boards, that Devon was evaluating a potential disposition process of its ownership interest in EnLink (the "Devon Sale") in connection with Devon's previously announced objective to monetize approximately $5 billion of its assets. Due to the notice of the potential Devon Sale, and considering the uncertainty created by that process, EnLink management, and the ENLC Conflicts Committee and the ENLK Conflicts Committee (collectively, the "Conflicts Committees") paused work with legal counsel regarding the potential Restructuring Alternatives. Prior to this time, neither the ENLC Conflicts Committee nor the ENLK Conflicts Committee had engaged a financial advisor with respect to a potential transaction.

        On January 13, 2018, the ENLC Conflicts Committee held a telephonic meeting with representatives of RLF and discussed the status of the potential transaction.

        At various meetings throughout January, February, and March 2018, EnLink management and Devon management met to discuss the potential Devon Sale, the process and timeline for such a transaction, potential acquirers, and the impact of such a transaction on EnLink's business and the various Restructuring Alternatives. During this time, EnLink management also met with Citi on multiple occasions to discuss the market for MLPs and other matters related to the various Restructuring Alternatives.

        On March 14, 2018, ENLC formally engaged Citi as its financial advisor in connection with a potential simplification transaction based on its reputation in the market, experience in the energy industry, and familiarity with EnLink from its experience acting as EnLink's financial advisor in several prior projects. Throughout April, May, and June 2018, EnLink management continued to meet with Citi to discuss Restructuring Alternatives, specifically focusing on an ENLC Simplification.

        On June 5, 2018, Devon and certain of its subsidiaries entered into a Purchase Agreement with GIP Stetson I and GIP Stetson II, each of which is an affiliate of GIP, pursuant to which GIP Stetson I and GIP Stetson II agreed to acquire, in the aggregate, all of the equity interests held by the Devon

36


Table of Contents

subsidiaries in ENLC, EMM, and ENLK for aggregate consideration of $3,125,000,000 in cash. On July 18, 2018, the Devon Sale was completed.

        On July 25, 2018, EnLink management met with representatives of GIP to discuss the Restructuring Alternatives and certain analyses prepared by Citi, including information regarding the process and general orientation with respect to the possible transactions to consummate the Restructuring Alternatives. On July 26, 2018, EnLink management discussed with representatives of Citi the impact of the possible Restructuring Alternatives on EnLink's credit rating.

        On August 1, 2018, EnLink held its earnings call for the second quarter of 2018, during which EnLink management noted that a "top priority" for ENLC was to evaluate the correct long-term organizational structure for EnLink that would provide a competitive cost of capital to fund its growth strategy.

        On August 13 and August 15, 2018, EnLink management met with representatives of Citi to discuss the Restructuring Alternatives, focusing specifically on an ENLC Simplification.

        On August 17, 2018, the EnLink Boards held a joint meeting to discuss the Restructuring Alternatives, focusing primarily on an ENLC Simplification, including the rationale for a potential transaction, the further analysis that would be required, and the anticipated next steps, timing, and processes. At this meeting, the ENLC Board and the ENLK Board re-authorized the ENLC Conflicts Committee and the ENLK Conflicts Committee, respectively, to engage a financial advisor in connection with the evaluation of a potential transaction involving the Restructuring Alternatives.

        On August 20, 2018, the ENLC Conflicts Committee held a telephonic meeting with representatives of RLF. The ENLC Conflicts Committee discussed engaging a financial advisor to assist the ENLC Conflicts Committee in connection with its evaluation of a potential transaction. The ENLC Conflicts Committee discussed the relative strengths of the potential advisors it had interviewed in January 2018 and the independence of each advisor. The ENLC Conflicts Committee determined that it would request updated information from Barclays regarding its material relationships with GIP and the EnLink family of companies and, subject to an acceptable disclosure, engage Barclays as its financial advisor, subject to negotiation of a mutually acceptable fee and engagement letter. The ENLC Conflicts Committee subsequently received a relationship disclosure letter from Barclays describing its material relationships with GIP and EnLink. On September 12, 2018, the ENLC Conflicts Committee entered into an engagement letter with Barclays. The ENLC Conflicts Committee selected Barclays due to, among other factors, its experience in the energy industry, including with respect to other simplification transactions, reputation, and familiarity with ENLC.

        On August 23, 2018, ENLK engaged Gibson, Dunn & Crutcher LLP ("Gibson Dunn") to act as its outside legal counsel in connection with a potential transaction.

        On August 24, 2018, the ENLK Conflicts Committee determined to discontinue the engagement of MNAT as legal counsel for the ENLK Conflicts Committee in connection with a potential transaction due to potential conflicts related to MNAT's representation of GIP on other matters. Also on August 24, 2018, the Chairman of the ENLK Conflicts Committee, on behalf of the ENLK Conflicts Committee, held a call with a representative of Potter Anderson & Corroon LLP ("Potter Anderson") for the purpose of determining whether to engage Potter Anderson as legal counsel to the ENLK Conflicts Committee in connection with a potential transaction. Thereafter, based on, among things, Potter Anderson's qualifications, experience representing MLP conflicts committees, and independence with respect to EnLink and GIP, the ENLK Conflicts Committee determined to engage Potter Anderson as legal counsel in connection with a potential transaction. An engagement letter detailing the terms of Potter Anderson's engagement was subsequently executed.

        Also on August 24, 2018, the Chairman of the ENLK Conflicts Committee, on behalf of the ENLK Conflicts Committee, held a call with representatives of Evercore to discuss the potential

engagement of Evercore as financial advisor to the ENLK Conflicts Committee. Thereafter, the ENLK Conflicts Committee determined, based on, among other things, Evercore's experience in the energy industry, experience with MLP simplification transactions, reputation and familiarity with EnLink, and in light of Evercore's prior engagements on behalf of the ENLK Conflicts Committee, to engage Evercore as financial advisor to the ENLK Conflicts Committee in connection with a potential transaction, subject to negotiation of a mutually acceptable fee and engagement letter. Evercore subsequently provided to the ENLK Conflicts Committee a relationship disclosure letter confirming Evercore's lack of material relationships with EnLink and GIP, other than Evercore's prior engagements by the ENLK Conflicts Committee. An engagement letter dated September 13, 2018 detailing the terms of Evercore's engagement was subsequently executed.

        On September 1, 2018, EnLink management called Christopher Ortega, a member of the ENLK Board who was designated by TPG, which, together with the Goldman Parties, are the owners of Enfield, the record holder of all of the ENLK Series B Units. During this call, EnLink management and Mr. Ortega discussed generally the possible treatment of the ENLK Series B Units in the potential transaction due to the fact that the ENLK Series B Units are convertible into ENLK Common Units, all of which would be exchanged for ENLC Common Units if the potential transaction involved an ENLC Simplification. Following this call on September 1, 2018, EnLink management sent to representatives of TPG and the Goldman Parties a draft term sheet reflecting a scenario in which all of the ENLK Series B Units would be converted into a new series of preferred units issued by ENLC in connection with the potential transaction. On September 7, 2018, EnLink management held a conference call with representatives of TPG and the Goldman Parties regarding the potential treatment of the ENLK Series B Units in connection with a potential transaction.

        In early September 2018, EnLink management, following a review of the potential financial impacts of the various Restructuring Alternatives and the pro forma impacts of any such transaction, determined that an ENLC Simplification was preferable to the IDR Restructuring and the ENLK Acquisition because the ENLC Simplification would provide a comprehensive solution to, among other things, reduce EnLink's overall cost of capital, simplify its organizational structure, improve trading liquidity, and generally improve access to the capital markets.

        On September 14, 2018, the ENLK Conflicts Committee held a telephonic meeting with representatives of Potter Anderson and Evercore in attendance. Among other things discussed during the meeting, Potter Anderson reviewed with the ENLK Conflicts Committee the form of resolutions to be considered by the ENLK Board at a joint board meeting to be held on September 19, 2018 and the ENLK Conflicts Committee's possible mandate and responsibilities thereunder. During the meeting, the ENLK Conflicts Committee considered and affirmed each member's independence and disinterestedness with respect to a potential transaction and satisfaction of the independence requirements for service as a member of the ENLK Conflicts Committee. The ENLK Conflicts Committee and its advisors then discussed the anticipated process for evaluating and negotiating a potential transaction.

        On September 18, 2018, the ENLC Conflicts Committee held a telephonic meeting with representatives of Barclays and RLF. The ENLC Conflicts Committee discussed organizational matters in anticipation of an ENLC Board meeting and management presentation scheduled for the following day regarding an ENLC Simplification (the "Proposed Transaction"). The RLF representatives explained the scope of draft ENLC Board resolutions that would delegate authority to the ENLC Conflicts Committee to review, evaluate, and negotiate the Proposed Transaction. Barclays presented information pertaining to the recent trend of simplification transactions in the midstream market. The ENLC Conflicts Committee discussed process and timing matters for evaluating the Proposed Transaction.

        On September 19, 2018, the EnLink Boards held a joint board meeting in Dallas, Texas to discuss the Restructuring Alternatives. In addition to EnLink management, representatives from Baker Botts, Citi, RLF, Barclays, Potter Anderson, Gibson Dunn, and Evercore attended this meeting in person. At this joint board meeting, representatives from Citi made a presentation regarding midstream market trends, including trends toward simplified organizational structures and governance, precedent simplification transactions, and the relative benefits and drawbacks of the various Restructuring Alternatives, including the financial impact on EnLink and the comprehensive solution provided by the Proposed Transaction. Citi's financial analysis applied an illustrative exchange ratio of 1.06 ENLC Common Units for each ENLK Common Unit for purposes of demonstrating the various financial impacts of the Proposed Transaction. The EnLink Boards and the advisors to ENLC, ENLK, and the Conflicts Committees reviewed and discussed Citi's presentation, in particular Citi's observation that the ENLK Common Units and ENLC Common Units, which previously traded in relative parity, experienced a decoupling in their relative trading values starting in early August 2018. EnLink management also proposed a process by which the Conflicts Committees and their advisors would continue their analysis and evaluation with respect to an appropriate exchange ratio assuming a potential transaction structured as an ENLC Simplification, following which the Conflicts Committees and their advisors would negotiate and finalize the material terms of a Proposed Transaction.

        At the September 19 meeting, each of the ENLC Board and the ENLK Board adopted resolutions (i) affirming that each of the members of the ENLC Conflicts Committee and the ENLK Conflicts Committee, respectively, satisfied the independence and other requirements to serve as members of the applicable Conflicts Committee and (ii) delegating to the ENLC Conflicts Committee and the ENLK Conflicts Committee, respectively, among other things, the power and authority to review, evaluate, and negotiate the terms and conditions, and determine the advisability of, a Proposed Transaction.

        Also at the September 19 meeting, EnLink management indicated that they intended to review the Proposed Transaction with credit ratings agencies to understand the agencies' perspective on such a transaction.

        Immediately following the joint board meeting, the ENLK Conflicts Committee held an in-person meeting with representatives of Potter Anderson and Evercore to discuss their impressions from the joint board meeting and their immediate reactions to Citi's presentation, as well as the role of the ENLK Conflicts Committee, the anticipated diligence process going forward and the appropriate level of oversight of negotiations regarding the treatment of the ENLK Series B Units.

        On September 20, 2018, EnLink management provided to each Conflicts Committee and its financial advisor certain financial information regarding ENLC and ENLK, including financial projections through fiscal year ended December 31, 2021 for ENLC, ENLK, and Pro Forma ENLC. See "—Unaudited Projected Financial Information."

        On September 21, 2018, EnLink management held a conference call with representatives of TPG and the Goldman Parties regarding the Proposed Transaction and the potential impact on the ENLK Series B Units.

        Also on September 21, 2018, representatives of Vinson & Elkins LLP ("V&E"), counsel to TPG, contacted Potter Anderson and expressed their view that the interests of the ENLK Series B Unitholders and the ENLK Common Unitholders were aligned with respect to the exchange ratio, and that, as the process moved forward, TPG wished to have the opportunity to provide input to the ENLK Conflicts Committee through communications between their respective bankers and through direct communications with the ENLK Conflicts Committee. Potter Anderson informed V&E that, subject to the ENLK Conflicts Committee's consideration of the request and further directions regarding the same, any such communications should first be arranged through Potter Anderson.

        On September 24, 2018, EnLink management held confidential meetings with the ratings agencies (S&P, Moody's, and Fitch) to determine the likely impact of the Proposed Transaction on the credit ratings of EnLink. In early October, each of the ratings agencies advised EnLink management of its expectation that EnLink's current ratings would be affirmed based upon the Proposed Transaction.

        In late September 2018, the financial advisors to the Conflicts Committees distributed due diligence requests and performed due diligence reviews of EnLink. An initial due diligence session was held with EnLink management and representatives of Evercore and Potter Anderson on September 26, 2018. EnLink management held a due diligence session with the ENLC Conflicts Committee and representatives of Barclays and RLF on September 28, 2018. During these diligence sessions, the parties discussed in detail various business, operating, and financial diligence matters, including key assumptions underlying EnLink management's projections. In the days following these sessions, EnLink management continued to provide representatives of Barclays and Evercore with additional requested due diligence information, and EnLink management and representatives of Barclays and Evercore each held follow-up due diligence calls.

        During the first week of October, EnLink management discussed several times the impact of the Proposed Transaction on the ENLK Series B Units (the "Series B Restructuring") with representatives of TPG and the Goldman Parties.

        On October 2, 2018, the ENLK Conflicts Committee held a telephonic meeting with representatives of Potter Anderson and Evercore, during which the ENLK Conflicts Committee and its advisors discussed, among other things, Evercore's financial diligence, the status of negotiations of the Series B Restructuring and related legal issues regarding the treatment of the ENLK Series B Units in the Proposed Transaction, and TPG's request to provide input for consideration by the ENLK Conflicts Committee. Evercore also presented a preliminary analysis to the ENLK Conflicts Committee of the financial terms of the Proposed Transaction. After deliberation with its advisors, the ENLK Conflicts Committee determined to provide to EnLink management a preliminary indication that an exchange ratio of 1.14 ENLC Common Units for each ENLK Common Unit in an ENLC Simplification would be appropriate, subject to further diligence and analysis, including with respect to tax implications, and subject to input from TPG. The ENLK Conflicts Committee also directed Evercore to confer with TPG's financial advisor regarding the Proposed Transaction so long as Evercore was in "listen-only mode" during such conference, meaning that Evercore would hear the views of such financial advisor but would not provide any information. Later in the evening of October 2, 2018, at the direction of the ENLK Conflicts Committee, representatives of Evercore provided to EnLink management the preliminary indication discussed during the ENLK Conflicts Committee meeting held earlier that day.

        On October 3, 2018, EnLink management distributed a draft term sheet reflecting the proposed Series B Restructuring to representatives of TPG and the Goldman Parties. The draft term sheet contemplated that the ENLK Series B Units would remain outstanding at ENLK following the consummation of the Proposed Transaction and that Enfield would be issued a new class of common units, which represented a non-economic, voting membership interest in ENLC in order to provide Enfield with substantially equivalent voting rights at ENLC following the Proposed Transaction as Enfield currently has with respect to ENLK.

        Also on October 3, 2018, representatives of V&E contacted Potter Anderson and requested a meeting between Evercore and Jefferies LLC, financial advisor to TPG ("Jefferies").

        On October 4, 2018, representatives of Evercore met telephonically with representatives of Jefferies, during which Evercore participated in "listen-only mode" and Jefferies provided its views as to certain aspects of EnLink's business prospects, forecasts, and diligence matters.

EnLink management also discussed, among other things, the contemplated treatment of the ENLK Series C Units in the Proposed Transaction and related legal issues, federal income tax considerations, pending litigation, and current contractual and regulatory compliance matters with respect to EnLink. During the session, the ENLK Conflicts Committee requested additional information concerning EnLink management's consideration of alternative structures for the Proposed Transaction including conversion of ENLC to a corporation and the merger of both ENLC and ENLK into a new entity. EnLink management provided responses to such questions during such due diligence session and through follow-up correspondence after such session.

        Immediately after the diligence session, the ENLK Conflicts Committee held a telephonic meeting with representatives of Potter Anderson and Evercore. Representatives of Evercore reviewed a list of questions and observations prepared by Jefferies with respect to EnLink management's assumptions and financial data discussed at the October 5 optional informational board session.

Among other things, the ENLK Conflicts Committee discussed current unit prices, Evercore's preliminary analysis of the financial terms of the Proposed Transaction and financial due diligence sessions with EnLink management, and TPG's input. Following discussion, the ENLK Conflicts Committee determined that an updated indication of an appropriate exchange ratio should be provided to EnLink management. The ENLK Conflicts Committee then determined that an exchange ratio of 1.20 ENLC Common Units for each ENLK Common Unit would be appropriate. Subsequently on such date, at the direction of the ENLK Conflicts Committee, representatives of Evercore provided to EnLink management the indication discussed at the ENLK Conflicts Committee meeting held earlier that day.

        On October 12, 2018, the ENLC Board held a special board meeting. At the meeting, ENLC management discussed the Proposed Transaction with the ENLC Board, including market receptivity for the Proposed Transaction, and informed the ENLC Board of management's view that an appropriate transaction would involve an acquisition by ENLC of all of the ENLK Common Units not already owned by ENLC or its subsidiaries at an exchange ratio of 1.10 ENLC Common Units for each ENLK Common Unit and the cancellation of the IDRs. The ENLC Board did not take any action with respect to the Proposed Transaction or management's viewpoint with respect to an appropriate transaction at such meeting. Following the meeting, EnLink management called the Chairman of the ENLK Conflicts Committee and communicated the viewpoint of EnLink management that (i) a fixed exchange ratio of 1.10 ENLC Common Units for each ENLK Common Unit would be appropriate for the Proposed Transaction and (ii) ENLC was only interested in a "roll-up"-styled simplification transaction involving the cancellation of the IDRs. A member of EnLink management followed this conversation with an email to the Chairman of the ENLK Conflicts Committee, copying the other member of the ENLK Conflicts Committee and representatives of Evercore, Potter Anderson, and EnLink management. In this email, EnLink management reiterated management's viewpoint, attached an initial draft of the Merger Agreement, and requested that the ENLK Conflicts Committee commence direct negotiations with the ENLC Conflicts Committee and its advisors regarding the

Early in the day, the ENLC Conflicts Committee held a telephonic meeting to discuss the status of the negotiations of the Proposed Transaction. Later that day, the ENLC Conflicts Committee held a telephonic meeting with representatives of Barclays and RLF. Barclays presented details of the proposed special pro rata distribution requested by the ENLK Conflicts Committee. RLF provided an overview of the issues raised by the ENLK Conflicts Committee's markup of the Merger Agreement. The ENLC Conflicts Committee and its advisors discussed making a counterproposal to the ENLK Conflicts Committee and directed RLF to initiate discussions with the various legal counsel regarding the terms of the Merger Agreement.

        In the morning of October 19, 2018, at the request of RLF, EnLink management, Baker Botts, and RLF held a telephonic meeting to discuss the revised draft of the Merger Agreement.

        Also in the morning of October 19, 2018, representatives of RLF, Gibson Dunn, and Potter Anderson held a conference call to discuss the special pro rata distribution requested by the ENLK Conflicts Committee.

        Later on October 19, 2018, representatives of Gibson Dunn, Potter Anderson, EnLink management, Baker Botts, and RLF met telephonically to discuss material issues reflected in the revised draft of the Merger Agreement and the related support agreements, including the special pro rata distribution and other distribution provisions, the majority of minority vote condition, and the parties' respective termination rights and effects of termination.

        During the afternoon of October 19, 2018, the ENLC Conflicts Committee held a telephonic meeting with representatives of RLF and Barclays. At the request of the ENLC Conflicts Committee, representatives of EnLink management joined the meeting. The ENLC Conflicts Committee explained that it had determined to offer an exchange ratio of 1.15 ENLC Common Units for each ENLK Common Unit. Management provided its reaction to such proposal.

        In the late afternoon of October 19, 2018, at the request of the ENLC Conflicts Committee, representatives of Barclays informed EnLink management and representatives of Evercore that, subject to negotiation of the Merger Agreement and related transaction documents and the delivery of the fairness opinion of Barclays, the members of the ENLC Conflicts Committee would support an exchange ratio of 1.15 ENLC Common Units for each ENLK Common Unit and such exchange ratio was a best and final offer.

        In the evening of October 19, 2018, the ENLK Conflicts Committee met telephonically with representatives of Potter Anderson and Evercore to discuss the ENLC Conflicts Committee's revised proposed exchange ratio of 1.15 ENLC Common Units for each ENLK Common Unit, which was conditioned on rejection of the majority of minority vote condition and the special pro rata distribution. After further consideration of the revised ENLC counterproposal, the ENLK Conflicts Committee determined that it would support a 1.15 exchange ratio and no longer insist on the majority of minority vote provision and the special pro rata distribution, subject to the satisfactory negotiation of open terms and finalization of the Merger Agreement and related transaction documents. The ENLK Conflicts Committee also discussed certain material provisions in the revised draft of the Merger Agreement with its advisors, and directed Gibson Dunn and Potter Anderson to, among other things, seek a reduction of the termination fee amount, attempt to obtain a GIP Support Agreement, and ensure that the Merger Agreement provides for declaration and payment of regular quarterly distributions by ENLK prior to the quarter in which the closing occurs. Subsequently, at the direction of the ENLK Conflicts Committee, representatives of Evercore contacted representatives of Barclays to communicate that the ENLK Conflicts Committee would support a 1.15 exchange ratio, subject to negotiation and documentation of open terms.

        On October 20, 2018, Baker Botts sent a revised draft of the Merger Agreement and the ENLK Support Agreement to Potter Anderson and Gibson Dunn, and copied EnLink management. The further revised draft of the Merger Agreement, among other things, (i) rejected the majority of minority vote condition, (ii) included a recital that GIP Stetson II would execute and deliver its irrevocable written consent concurrently with the execution of the Merger Agreement but rejected the requirement that GP Stetson II deliver the GIP Support Agreement, (iii) rejected the special pro rata distribution but retained the ENLK obligation to declare and pay quarterly distributions in the ordinary course and consistent with past practice during the interim period in an amount per quarter of at least $0.39 per ENLK Common Unit outstanding, for each quarter preceding the quarter in which the closing occurs, (iv) restored the obligation of the parties to reimburse the expenses of the other party in certain circumstances, (v) restored the force-the-vote provision, (vi) restored the obligation for ENLK to pay a $62.5 million termination fee for termination in connection with a change of recommendation and for a termination in connection with a superior proposal, and added an obligation of ENLK to pay the termination fee in the event the Merger Agreement is terminated by either party as a result of the failure to obtain the approval of the ENLK Voting Unitholders when prior to the ENLK Unitholder Meeting a recommendation change had occurred, and (vii) revised certain provisions requiring the ENLK Conflicts Committee approval to authorize ENLK actions under the Merger Agreement so that such provisions required only prior notice to the ENLK Conflicts Committee and provided the ENLK Conflicts Committee the ability to revoke its "Special Approval" of the Merger Agreement if ENLK takes action contrary to any recommendation of the ENLK Conflicts Committee. The revised draft of the ENLK Support Agreement deleted the requirement that, upon a change of recommendation by the ENLK Conflicts Committee or ENLK Board, the Supporting Common Unitholders would be obligated to vote their ENLK Voting Units in the same proportion as the vote of the ENLK Unaffiliated Unitholders.

        In the afternoon of October 20, 2018, Gibson Dunn, at the request of the ENLK Conflicts Committee, delivered a revised draft of the Merger Agreement to Baker Botts and RLF, and copied EnLink management. This revised draft of the Merger Agreement, among other things, (i) reduced the termination fee payable by ENLK in certain circumstances from $62.5 million to $50 million, (ii) removed the obligation of ENLK to pay a termination fee in the event the Merger Agreement is terminated by either party as a result of the failure to obtain the approval of the ENLK Voting Unitholders when prior to the ENLK Unitholder Meeting a recommendation change had occurred, and (iii) reinserted an obligation for GIP Stetson II to deliver the GIP Support Agreement concurrently with the execution of the Merger Agreement with respect to its written consent to the ENLC Merger Issuance.

        Also in the afternoon of October 20, 2018, the ENLK Conflicts Committee held a telephonic meeting with representatives of Potter Anderson, Evercore, and Gibson Dunn in attendance. At the meeting, among other things, representatives of Potter Anderson and Gibson Dunn updated the ENLK Conflicts Committee as to the status of negotiations regarding the Merger Agreement and the terms and conditions of the Proposed Transaction. Potter Anderson also provided an update to the ENLK Conflicts Committee on the status of EnLink management's negotiations relating to the Series B Restructuring, which were near completion according to EnLink management.

        Later in the afternoon on October 20, 2018, EnLink management met via conference call with representatives of Baker Botts, RLF, Potter Anderson, and Gibson Dunn to discuss the outstanding issues in the further revised Merger Agreement and the related support agreements, including, among other things, the amount of the termination fee and events triggering payment of the termination fee, and the execution by GIP Stetson II of a GIP Support Agreement.

        On the evening of October 20, 2018, representatives of Baker Botts distributed a revised draft of the Merger Agreement that, among other things, increased the termination fee to $55 million and provided for the delivery by GIP Stetson II of the GIP Support Agreement.

        Over the course of October 20, 2018 and October 21, 2018, representatives of EnLink management, Baker Botts, and RLF, in consultation with the ENLC Conflicts Committee, and representatives of Gibson Dunn, and Potter Anderson, in consultation with the ENLK Conflicts Committee, participated in multiple conference calls and exchanged emails to negotiate and finalize the terms of the proposed Merger Agreement, the ENLK Support Agreement, the GIP Support Agreement, and other transaction documents.

        Meanwhile, over the course of October 19, October 20, and October 21, 2018, representatives of V&E and Baker Botts, in consultation with EnLink management, participated in multiple conference calls and exchanged emails to negotiate and finalize the terms of the proposed Series B Documents. During this period, representatives of Baker Botts and EnLink management consistently provided updates to each Conflicts Committee and its advisors regarding the status of negotiations with TPG and the Goldman Parties regarding the Series B Restructuring and the Series B Documents.

        In the evening of October 20, 2018, Baker Botts distributed to V&E a draft of the Enfield Support Agreement. Pursuant to the Enfield Support Agreement, subject to the conditions set forth therein, Enfield would agree to vote its ENLK Series B Units in favor of the approval of the ENLK Merger Proposal and, if necessary, the ENLK Adjournment Proposal. During the day on October 21, 2018, representatives of V&E and Baker Botts met telephonically and negotiated the terms and conditions of the Preferred Restructuring Agreement and the Enfield Support Agreement.

        On October 21, 2018, the ENLC Conflicts Committee met telephonically with the representatives of RLF and Barclays to discuss the Proposed Transaction, including the terms and conditions of the Merger Agreement, the Series B Restructuring, and the other transaction documents. Prior to the meeting, substantially final versions of the Merger Agreement, the Support Agreements, and the Series B Documents, along with summaries of the transaction documents, were distributed to the ENLC Conflicts Committee. During the meeting, a representative of Baker Botts joined to summarize the terms of the Series B Restructuring and the Series B Documents. In addition, RLF presented to the ENLC Conflicts Committee an overview and update regarding the terms of the Merger Agreement and other transaction documents. Also at this meeting, Barclays reviewed its financial analysis of the proposed exchange ratio with the ENLC Conflicts Committee and, at the request of the ENLC Conflicts Committee, rendered an oral opinion to the ENLC Conflicts Committee, which was subsequently confirmed by delivery of a written opinion dated as of October 21, 2018, to the effect that, based upon and subject to the qualifications and assumptions set forth therein, as of the date thereof, from a financial point of view, the Exchange Ratio to be paid by ENLC in the Proposed Transaction is fair to ENLC. At this meeting, the ENLC Conflicts Committee unanimously

        On October 21, 2018, the ENLK Conflicts Committee met telephonically to discuss the Proposed Transaction, including the terms and conditions of the Merger Agreement, the Series B Restructuring, and the other transaction documents. Prior to the meeting, substantially final versions of the Merger Agreement, the Support Agreements, and the Series B Documents, along with summaries of the transaction documents, were distributed to the ENLK Conflicts Committee. During the meeting, representatives of Potter Anderson summarized the terms of the Merger Agreement, the Support Agreements and the Series B Documents. Also at this meeting, representatives of Evercore presented its financial analysis of the Exchange Ratio and, at the request of the ENLK Conflicts Committee, rendered an oral opinion to the ENLK Conflicts Committee, which was subsequently confirmed by delivery of a written opinion dated as of October 21, 2018, to the effect that, as of such date and based upon and subject to the assumptions made, procedures followed, matters considered, and qualifications and limitations of the review undertaken by Evercore in rendering its opinion as set forth therein, the Exchange Ratio was fair, from a financial point of view, to the ENLK Unaffiliated Unitholders. After further deliberations, the ENLK Conflicts Committee unanimously (i) determined that the Merger Agreement and the Proposed Transaction are fair and reasonable to, and in the best interest of, ENLK and the ENLK Public Unitholders, (ii) approved (such approval constituting "Special Approval" for all purposes under the ENLK Partnership Agreement), and recommended that the ENLK Board approve, the Merger Agreement and the other transaction documents, and recommended that the ENLK Board submit the Merger Agreement for the approval of the ENLK Voting Unitholders, and (iii) resolved, and recommended that the ENLK Board resolve, to recommend approval of the Merger Agreement to the ENLK Voting Unitholders. See "—Recommendation of the ENLK Conflicts Committee and the ENLK Board, and the Reasons of the ENLK Conflicts Committee for Recommending Approval of the Transactions."

        On October 21, 2018, the EnLink Boards held a joint telephonic meeting attended by EnLink management and representatives of Baker Botts, Citi, RLF, Barclays, Potter Anderson, Gibson Dunn, and Evercore. At this meeting, a representative of Citi gave a presentation regarding the financial impacts of the Proposed Transaction, including the accretion to unitholders, and the relative public valuation of ENLC and ENLK. A representative of Baker Botts described the material terms of the Merger Agreement, and EnLink management summarized the terms of the Series B Restructuring. The EnLink Boards generally discussed the Proposed Transaction and the relevant Transaction Documents and adjourned the joint meeting without taking any action with respect to the Proposed Transaction itself.

        At the telephonic meeting of the ENLK Board, the members of the ENLK Conflicts Committee reviewed the work completed to date by the financial and legal advisors to the ENLK Conflicts Committee and reported the results of the meeting of the ENLK Conflicts Committee described above, and the ENLK Board unanimously adopted resolutions approving the Proposed Transaction, including the Merger Agreement and the other Transaction Documents.

Committee and reported the results of the meeting of the ENLC Conflicts Committee described above, and the ENLC Board unanimously adopted resolutions approving the Proposed Transaction, including the Merger Agreement and the other Transaction Documents. Pursuant to the resolutions of the ENLC Board, among other things, the ENLC Board unanimously directed that the ENLC Unit Issuance be submitted for the approval of GIP Stetson II by written consent.

        Later on October 21, 2018, ENLC and ENLK executed the Merger Agreement.

        On October 22, 2018, ENLC and ENLK issued a joint press release announcing the execution of the Merger Agreement.

Recommendation of the ENLC Conflicts Committee and Its Reasons for Recommending Approval of the Transactions

        The ENLC Conflicts Committee consists of two independent directors: James C. Crain (Chair) and Rolf A. Gafvert, each of whom the ENLC Board determined satisfied the independence and other requirements set forth in the ENLC Operating Agreement to serve as a member of the ENLC Conflicts Committee. The ENLC Board delegated to the ENLC Conflicts Committee, among other things, the power and authority (i) to make such investigation of the Proposed Transaction, the other Restructuring Alternatives, and the alternative of maintaining the status quo, as the ENLC Conflicts Committee deemed necessary or appropriate, (ii) to review, evaluate, and negotiate (or to supervise and direct the negotiations on behalf of ENLC with respect to) the terms and conditions, and determine the advisability, of the Proposed Transaction and related agreements and arrangements, (iii) to determine whether the Proposed Transaction is fair to, and in the best interest of, ENLC and the ENLC Public Unitholders, (iv) to determine whether to approve the Proposed Transaction (with such approval constituting "Special Approval" for all purposes under the ENLC Operating Agreement), and to make a recommendation to the ENLC Board whether to approve the Proposed Transaction, and (v) to make any recommendations to the ENLC Board regarding the Proposed Transaction as the ENLC Conflicts Committee determined to be appropriate.

        On October 21, 2018, the ENLC Conflicts Committee unanimously (i) determined in good faith that the Merger Agreement and the other Transaction Documents, and the Transactions, including the Merger, the ENLC Unit Issuance and the other transactions contemplated by the Merger Agreement and the other Transaction Documents, on the terms and conditions set forth in the Merger Agreement and the other Transaction Documents, are fair to, and in the best interests of, ENLC and the ENLC Public Unitholders, (ii) approved the Merger Agreement and the other Transaction Documents and the Transactions, including the Merger, the ENLC Unit Issuance and the other transactions contemplated by the Merger Agreement and the other Transaction Documents, upon the terms and conditions set forth in the Merger Agreement and the other Transaction Documents, (iii) recommended to the ENLC Board that the ENLC Board approve the Merger Agreement and the other Transaction Documents and the Transactions, including the Merger, the ENLC Unit Issuance and the other transactions contemplated by the Merger Agreement and the other Transaction Documents, upon the terms and conditions set forth in the Merger Agreement and the other Transaction Documents, and submit the ENLC Unit Issuance for the approval of the ENLC Unitholders in accordance with Section 312.03(c) of the Listed Company Manual of the New York Stock Exchange, (iv) recommended, and recommended to the ENLC Board to recommend, to the ENLC Unitholders that the ENLC Unitholders approve the ENLC Unit Issuance, upon the terms and conditions set forth in the Merger Agreement and the other Transaction Documents.

        The foregoing discussion of the information and factors considered by the ENLC Conflicts Committee is not intended to be exhaustive, but includes material factors the committee considered. In view of the variety of factors considered in connection with its evaluation of the Transactions and the complexity of these matters, the ENLC Conflicts Committee did not find it useful and did not attempt to quantify or assign any relative or specific weights to the various factors considered in making its determination and recommendation. In addition, each of the members of the ENLC Conflicts Committee may have given differing weights to different factors. Overall, the committee believed that the positive factors supporting the Transactions outweighed the negative factors it considered.

Opinion of Barclays—Financial Advisor to the ENLC Conflicts Committee

        The ENLC Conflicts Committee engaged Barclays to act as the ENLC Conflicts Committee's financial advisor with respect to the Transactions. On October 21, 2018, Barclays rendered its oral opinion (which was subsequently confirmed in writing) to the ENLC Conflicts Committee that, as of such date and based upon and subject to the qualifications, limitations, and assumptions stated in its opinion, from a financial point of view, the Exchange Ratio to be paid by ENLC in the Transactions is fair to ENLC.

        The full text of Barclays' written opinion, dated as of October 21, 2018, is attached to this joint information statement/proxy statement/prospectus as Annex F. 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

53


Table of Contents

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 ENLC Conflicts Committee, addresses only the fairness to ENLC, from a financial point of view, of the Exchange Ratio to be paid by ENLC in the Transactions and does not constitute a recommendation to any unitholder of ENLC or any other person as to how such unitholder or other person should vote with respect to the Transactions. The terms of the Transactions were determined through arm's-length negotiations between ENLC and ENLK and were approved unanimously by the ENLC Conflicts Committee. Barclays did not recommend that any specific form of consideration should be offered in the Transactions or that any specific form of consideration constituted the only appropriate consideration for the Transactions. 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 Transactions or the likelihood of consummation of the Transactions or the relative merits of the Transactions as compared to any other transaction or business strategy in which ENLC 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 Transactions, or any class of such persons, relative to the Exchange Ratio in the Transactions or otherwise. No limitations were imposed by the ENLC 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:

54


Table of Contents

        In addition, Barclays has had discussions with management of ENLC concerning the business, operations, assets, liabilities, financial condition, and prospects of ENLC and ENLK 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 had further relied upon the assurances of ENLC that it is not aware of any facts or circumstances that would make such information inaccurate or misleading. With respect to the Projections, Barclays assumed (i) upon the advice of management of ENLC, that such projections were reasonably prepared on a basis reflecting the best currently available estimates and judgments of management of ENLC as to the future financial performance of ENLC and ENLK and (ii) that ENLC and ENLK would perform substantially in accordance with such projections. 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 arriving at its opinion, Barclays did not conduct a physical inspection of the properties and facilities of ENLC or ENLK and did not make or obtain any evaluations or appraisals of the assets or liabilities of ENLC or ENLK. Barclays' opinion was necessarily based upon market, economic, and other conditions as they existed on, and could be evaluated as of, the date of its letter. Barclays assumed no responsibility for updating or revising its opinion based on events or circumstances that may have occurred after the date of its letter. Barclays expressed no opinion as to (i) the prices at which the ENLK Common Units or the ENLC Common Units would trade following the announcement of the Transactions or (ii) the prices at which the ENLC Common Units would trade following consummation of the Transactions.

        Barclays assumed the accuracy of the representations and warranties contained in the Merger Agreement and all agreements related thereto. Barclays also assumed, upon the advice of management of ENLC and at the instruction of the ENLC Conflicts Committee, that all material governmental, regulatory, and third party approvals, consents, and releases for the Transactions would be obtained within the constraints contemplated by the Merger Agreement and that the Transactions would be consummated in accordance with the terms of the Merger Agreement without waiver, modification, or amendment of any material term, condition, or agreement thereof and that the terms of the ENLK Series B Units would be amended substantially as set forth in the Amended ENLK Partnership Agreement and Preferred Restructuring Agreement, but Barclays expressed no opinion as to the fairness, from a financial point of view of such amendments, to any person. Barclays did not express any opinion as to any tax or other consequences that might result from the Transactions, nor did its opinion address any legal, tax, regulatory, or accounting matters, as to which Barclays understood that the ENLC Conflicts Committee and ENLC 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 ENLK Public Units or the ENLC Common Units but rather made its determination as to fairness, from a financial point of view, to ENLC of the Exchange Ratio to be paid by ENLC in the Transactions 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

55


Table of Contents

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 ENLC and ENLK in preparing Barclays' opinion:

        Each of these methodologies was used to generate reference per unit equity value ranges for ENLK Common Units to the ENLC 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 ENLC and ENLK was then divided by an applicable estimate of the number of diluted units estimated to be outstanding. For purposes of the ENLK calculations, the number of diluted units outstanding at June 30, 2018, per ENLC management, 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. In order to derive the implied exchange ratios in its analysis, the high end of the exchange ratio range was calculated by dividing the high value of the ENLK reference range by the low value of the ELNC reference range and the low end of the exchange ratio range was calculated by dividing the low value of the ENLK reference range and the high value of the ENLC reference range. For purposes of the ENLC calculations, the number of diluted units outstanding at June 30, 2018, per ENLC management, was used to derive implied per unit values. 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 exchange ratio ranges were then compared to the Exchange Ratio of 1.15 ENLC Common Units for each ENLK Public Unit in the Transactions.

        In addition to analyzing the value of ENLK Common Units and ENLC Common Units, to provide additional background and perspective to the ENLC Conflicts Committee, Barclays also analyzed and reviewed: (i) the daily historical closing prices of ENLK Common Units and ENLC Common Units and the exchange ratios implied by those closing unit prices for the period from October 19, 2015 to October 19, 2018; (ii) certain publicly available information related to selected affiliated 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 Transactions on the current and future financial performance of Pro Forma ENLC using projected estimates for 2019, 2020, and 2021 for distributable cash flow per unit and distributions per unit for Pro Forma ENLC based on the Projections and (iv) analysis of public third-party equity research analyst price targets of ENLC and ENLK.

        In particular, in applying the various valuation methodologies to the particular businesses, operations and prospects of ENLC and ENLK, and the particular circumstances of the Transactions, 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 ENLC and ENLK. Such qualitative judgments and assumptions of Barclays were made following discussions with the management of ENLC. 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

56


Table of Contents

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 ENLC, ENLK or any other parties to the Transactions. No company, business or transaction considered in Barclays' analyses and reviews is identical to ENLC, ENLK, or the Transactions, 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 the ENLC Conflicts Committee, ENLC, ENLK, Barclays, or any of their respective members, officers, employees, advisors, representatives, 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 ENLK Common Units and ENLC Common Units, Barclays performed discounted distributable cash flow analyses for each of ENLC and ENLK. 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 ENLK Common Units and ENLC 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.

        Barclays performed the discounted distributable cash flow analysis for ENLK Common Units and ENLC Common Units using estimated EBITDA from 2019 through 2023 based on EnLink management's estimated EBITDA from 2019 through 2021 per the Projections, with 2022 and 2023 estimates extrapolated by Barclays from 2021 estimates assuming a 1.5% growth rate year-over-year. To calculate the estimated per ENLK Common Unit equity value ranges in the discounted distributable

57


Table of Contents

cash flow analysis, Barclays added (i) projected distributable cash flow per ENLK Common Unit for fiscal years 2019 through 2023 (with 2019 through 2021 being included in the Projections and Barclays extrapolating for 2022 and 2023) to (ii) the terminal value at the end of the forecast period, or the "terminal value" of ENLK Common Units, as of December 31, 2023 (as estimated by Barclays as described below), and discounted such distributable cash flows per ENLK Common Unit to their net present value as of January 1, 2019 using selected discount rates. Barclays used a nominal discount rate range of 11.0% to 13.0%. This discount rate range was selected by Barclays using its professional judgment and experience, taking into account projected cost of equity capital rates for ENLK and the comparable companies utilized in the Selected Comparable Companies Analysis described below. Barclays estimated the terminal value of ENLK Common Units by applying a range of assumed yields of 9.0% to 10.0% to the estimated distributable cash flow per ENLK Common Unit for 2023 as extrapolated by Barclays, as described above. The assumed yields were selected by Barclays based on Barclays' professional judgment and experience, taking into account the yields of ENLK and the selected comparable companies utilized in the Selected Comparable Companies Analysis described below. The reference equity value range per ENLK Common Unit determined based on the ENLK discounted distributable cash flow analysis implied an equity value range for ENLK Common Units of $17.00 to $20.00 per ENLK Common Unit, as compared to the closing ENLK Common Unit price of $18.26 on October 19, 2018.

        To calculate the estimated per ENLC Common Unit equity value ranges in the discounted distributable cash flow analysis for ENLC, Barclays added (i) projected distributable cash flow per ENLC Common Unit for fiscal years 2019 through 2023 (with 2019 through 2021 being included in the Projections and Barclays extrapolating for 2022 and 2023) to (ii) the terminal value of ENLC Common Units, as of December 31, 2023 (as estimated by Barclays as described below), and discounted such distributable cash flows per ENLC 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 ENLC and the selected comparable companies utilized in the Selected Comparable Companies Analysis described below. Barclays estimated the terminal value of ENLC Common Units by applying a range of assumed yields of 8.50% to 9.50% to the estimated distributable cash flow per ENLC Common Unit for 2023 as extrapolated by Barclays, as described above. The assumed yields were selected by Barclays based on Barclays' professional judgment and experience, taking into account the yields of ENLC and the selected comparable companies utilized in the Selected Comparable Companies Analysis described below. The reference equity value range for ENLC Common Units determined based on the ENLC discounted distributable cash flow analysis implied an equity value range for ENLC of $16.00 to $19.00 per ENLC Common Unit, as compared to the closing ENLC Common Unit price of $16.05 on October 19, 2018.

        Using the implied reference equity value per unit ranges for each of ENLK Common Units and ENLC Common Units, Barclays derived reference implied exchange ratio ranges of 0.8947x to 1.2500x.

        Barclays noted that the Exchange Ratio of 1.15 to be offered by ENLC in the Transactions was within the implied exchange ratio range determined based on 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 ENLC Common Unit and per ENLK 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 ENLC and ENLK 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 ENLK were:

        Barclays calculated and compared various financial multiples and ratios of ENLC and ENLK and the selected comparable companies. As part of its selected comparable company analysis, Barclays calculated and analyzed latest quarter annualized ("LQA") distribution yield multiples using published estimates by third party equity research analysts for estimated distributable cash flow per unit and earnings before interest, taxes, depreciation, and amortization ("EBITDA") in 2019 and distribution yield in 2019 for each of the comparable companies selected and for ENLK using the Projections. All of these calculations were performed on 2019E provided by ENLC management, and based on publicly available financial data and closing prices, as of October 19, 2018, the last trading date prior to the delivery of Barclays' opinion. The results of the ENLK selected comparable company analysis are summarized below:

 
  Yield Range of
Comparable MLPs of
ENLK
 
LQA Distribution Yield:
  Low   Median   High  

LQA Yield

    4.87 %   7.66 %   15.68 %

        Barclays selected the comparable midstream corporations and MLPs listed above because their business and operating profiles are reasonably similar to that of ENLK. However, because of the inherent differences between the business, operations, and prospects of ENLK 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 ENLK 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 ENLK and the selected midstream corporations and MLPs included in the selected comparable company analysis. The equity value range for ENLK Common Units determined based on the ENLK selected comparable company analysis implied a reference equity value range for ENLK of $18.00 to $22.00 per ENLK Common Unit.

        The general partners selected with respect to ENLC were:

Table of Contents

        Barclays calculated and analyzed the implied general partner value as a multiple of general partner ("GP") 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 ENLC using the Projections. The selected range of multiples was applied to the 2019E and 2020E GP IDRs for ENLC as stated in the Projections. The results of the ENLC selected comparable company analysis are summarized below:

 
  Multiple Range of
Comparable General
Partners of ENLC
 
General Partner Value as a multiple of:

2019E General Partner Distributions

    11.5x     11.8x     19.8x  

2020E General Partner Distributions

    9.2x     10.0x     13.1x  

        Barclays selected the comparable general partners listed above because their business and operating profiles are reasonably similar to that of ENLC. However, because of the inherent differences between the business, operations, and prospects of ENLC 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 ENLC 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 ENLC and the selected general partners included in the selected comparable company analysis. The equity value range for ENLC Common Units determined based on the ENLC comparable company analysis implied a reference equity value range for ENLC of $16.00 to $19.00 per ENLC Common Unit.

        Using the implied reference equity value per unit ranges for each of ENLC and ENLK, Barclays derived a reference implied exchange ratio range of 0.9474x to 1.3750x.

        Barclays noted that the Exchange Ratio of 1.15 to be offered by ENLC in the Transactions was within the implied exchange ratio range determined based on 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 ENLC and ENLK with respect principally to size and operational focus. Each of the selected transactions was an acquisition of an MLP announced between June 2009 and October 2018. None of the transactions selected based on the

        Using publicly available information, Barclays calculated and analyzed multiples of enterprise value ("EV") to last twelve month ("LTM") EBITDA ("LTM EBITDA") represented by the prices paid in the above selected precedent transactions. The selected range of multiples was applied to the 2019E EBITDA for ENLK as stated in the Projections. The results of the selected precedent transactions analysis are summarized below:

 
  EV / LTM EBITDA  
EV as a Multiple of:
  Low   Median   Mean   High  

LTM EBITDA

    7.4x     11.1x     11.7x     26.0x  

        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 ENLK 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 Transactions. Barclays therefore made qualitative judgments concerning differences between the characteristics of the selected precedent transactions and the Transactions which would affect the acquisition values of the selected target companies and ENLK. Based upon these judgments, Barclays' selected precedent transactions analysis yielded a reference equity value range for ENLK Common Units of $18.00 to $21.00 per ENLK 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 partner merger transactions based on, among

61

other things, the similarity of the applicable companies to ENLC 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 February 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 LQA distributions to the general partner represented by the prices paid in the selected precedent transactions. The selected range of multiples was applied to the 2019E GP IDRs for ENLC as stated in the Projections. The results of the selected precedent transactions analysis are summarized below:

 
  General Partner Value / LQA GP

General Partner Value as a Multiple of:
  Low   Median   Mean   High  

LQA GP Distribution

    8.8x     20.4x     37.2x     183.5x  

        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 ENLC 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 Transactions. Barclays therefore made qualitative judgments concerning differences between the characteristics of the selected precedent transactions and the Transactions which would affect the acquisition values of the selected target companies and ENLC. Based upon these judgments, Barclays selected precedent transactions analysis yielded a reference equity value range for ENLC Common Units of $15.00 to $17.00 per ENLC Common Unit.

        Using the implied reference equity value per unit ranges for each of ENLK Common Units and ENLC Common Units, Barclays also derived a reference implied exchange ratio range of 1.0588x to 1.4000x.

        Barclays noted that the Exchange Ratio of 1.15 to be offered by ENLC in the Transactions was within the implied exchange ratio range determined based on Barclays' selected precedent transactions analysis.

Other Factors

        To provide background information and perspective to the ENLC Conflicts Committee, Barclays reviewed and compared, as of October 19, 2018, the publicly available price targets of ENLK Common Units and ENLC Common Units published by equity research analysts associated with various Wall Street firms, of which there were 14 and 13, respectively (including Barclays' equity research analyst price targets for each of ENLC and ENLK). The research analysts' price targets per ENLC Common Unit ranged from $16.00 to $22.00 and per ENLK Common Unit ranged from $16.00 to $20.00. The publicly available unit price targets published by such equity research analysts do not necessarily reflect the current market trading prices for ENLK Common Units or ENLC Common Units and these estimates are subject to uncertainties, including future financial performance of ENLC and ENLK and future market conditions. Using the implied reference equity value per unit ranges for each of ENLK Common Units and ENLC Common Units, Barclays also derived a reference implied exchange ratio range of 0.7273x to 1.2500x. Barclays noted that the Exchange Ratio of 1.15 to be offered by ENLC in the Transactions was within the implied exchange ratio range determined based on Barclays' equity research analyst price targets.

        In order to provide background information and perspective to, and to assess the Exchange Ratio offered by ENLC in the Transactions, Barclays reviewed and analyzed the implied exchange ratio in the Transactions based on the "Heads-Up" exchange ratios, which reflects the implied exchange ratio of ENLK Common Units to the ENLC Common Unit trading prices without considering any adjustments, and the implied premium in the Transactions based on the historical unit price, each as of October 19, 2018 and the (i) 5-day, 10-day, 30-day and 60-day prior to current, (ii) 30-day, 60-day, 180-day and 1-year average, and (iii) 5-day, 10-day, and 30-day volume weighted average prices ("VWAP") of ENLK Common Units to the ENLC Common Units. The table below sets forth the summary results of the analysis:

        Barclays also reviewed and analyzed the implied exchange ratio in the Transactions based on a review of precedent premiums paid from selected historical precedent transactions, whereby Barclays

63


Table of Contents

reviewed the unaffected and spot precedent premiums paid. The unaffected premiums paid analysis implied relative exchange ratios ranging from a low of 1.0119x to a high of 1.2528x ENLK Common Units per ENLC Common Unit and the spot precedent premiums paid analysis implied relative exchange ratios ranging from a low of 1.0808x to a high of 1.4221x ENLK Common Units per ENLC Common Unit. Barclays noted that the Exchange Ratio to be offered by ENLC in the Transactions was within the implied relative exchange ratio range.

        Barclays reviewed and analyzed the pro forma impact of the transaction on projected distributable cash flow and distributions of Pro Forma ENLC for each of 2019, 2020, and 2021 using the Projections under two scenarios, one assuming 1.4000x coverage (the "1.40x Coverage Scenario") and a second assuming status quo coverage ratio of 1.2100x for 2019, 1.1600x for 2020 and 1.2000x for 2021 (the "Status Quo Coverage Scenario"). The table below sets forth the summary results of the accretion analysis:

        Barclays is an internationally recognized investment banking firm and, as part of its investment banking activities, is regularly engaged in the valuation of businesses and their securities in connection with mergers and acquisitions, investments for passive and control purposes, negotiated underwritings, competitive bids, secondary distributions of listed and unlisted securities, private placements, and valuations for estate, corporate, and other purposes. The ENLC Conflicts Committee selected Barclays because of its familiarity with ENLC and ENLK, and because of Barclays' qualifications, reputation and experience in the valuation of businesses and securities in connection with mergers and acquisitions generally, knowledge of the industries in which ENLC and ENLK operate, as well as substantial experience in transactions comparable to the Transactions.

        Barclays is acting as financial advisor to the ENLC Conflicts Committee in connection with the Transactions. As compensation for its services in connection with the Transactions, ENLC will pay Barclays a fee of $2.5 million, conditioned upon and payable upon closing of the Transactions. In addition, ENLC paid Barclays a fee of $500,000 upon delivery of the opinion, which is referred to as the "Opinion Fee". The Opinion Fee was not contingent upon the conclusion of Barclays' opinion. In addition, Barclays may receive a discretionary fee of $500,000 based on the ENLC Conflict Committee's assessment of the quality and quantity of work completed by Barclays in connect with its engagement for the Transactions, which is referred to as the "Discretionary Fee". In addition, ENLC has agreed to reimburse Barclays for certain of its expenses incurred in connection with the Transactions and to indemnify Barclays for certain liabilities that may arise out of its engagement by the ENLC Conflicts Committee and the rendering of Barclays' opinion. Barclays has performed various investment banking services for ENLC and ENLK and their affiliates in the past, and expects to perform such services in the future, and has received, and expects to receive, customary fees for such

services. Specifically, in the past two years, Barclays has performed the following investment banking and financial services: acting as (i) active bookrunner on ENLK's $500mm Senior Unsecured Notes in May 2017, (ii) sales agent on ENLK's $600mm ATM equity offering in August 2017 and (iii) lender under ENLK's existing revolving credit facility. In addition, Barclays and its affiliates in the past have provided, currently are providing, or in the future may provide, investment banking services to GIP, and certain of its affiliates and portfolio companies and have received or in the future may receive customary fees for rendering such services, including (i) having acted or acting as financial advisor to GIP and certain of its portfolio companies and affiliates in connection with certain mergers and acquisition transactions; (ii) having acted or acting as arranger, bookrunner, and/or lender for GIP and certain of its portfolio companies and affiliates in connection with the financing for various acquisition transactions; and (iii) having acted or acting as underwriter, initial purchaser, and placement agent for various equity and debt offerings undertaking by GIP and certain of its funds' portfolio companies and affiliates. During the past two years, the aggregate fees received by Barclays from ENLC, ENLK, and their respective affiliates, including GIP, were approximately $3 million.

        Barclays, its subsidiaries and affiliates engage in a wide range of businesses from investment and commercial banking, lending, asset management and other financial and non-financial services. In the ordinary course of its business, Barclays and its affiliates may actively trade and effect transactions in the equity, debt and/or other securities (and any derivatives thereof) and financial instruments (including loans and other obligations) of ENLC and ENLK for its own account and for the accounts of its customers and, accordingly, may at any time hold long or short positions and investments in such securities and financial instruments.

Recommendation of the ENLK Conflicts Committee and the ENLK Board, and the Reasons of the ENLK Conflicts Committee for Recommending Approval of the Transactions

        The ENLK Conflicts Committee consists of two independent directors: Kyle D. Vann (Chair) and Scott A. Griffiths, each of whom the ENLK Board determined satisfied the independence and other requirements set forth in the ENLK Partnership Agreement to serve as a member of the ENLK Conflicts Committee. The ENLK Board delegated to the ENLK Conflicts Committee the power and authority (i) to make such investigation of the Proposed Transaction, the other Restructuring Alternatives, and the alternative of maintaining the status quo, as the ENLK Conflicts Committee deemed necessary or appropriate, (ii) to review, evaluate, and negotiate (or to supervise and direct the negotiations on behalf of ENLK with respect to) the terms and conditions, and determine the advisability, of the Proposed Transaction and related agreements and arrangements, (iii) to determine whether the Proposed Transaction is fair and reasonable to, and in the best interest of, ENLK and the ENLK Unaffiliated Unitholders, (iv) to determine whether to approve the Proposed Transaction (with such approval constituting "Special Approval" for all purposes under the ENLK Partnership Agreement), and to make a recommendation to the ENLK Board whether to approve the Proposed Transaction, and (v) to make any recommendations to the ENLK Board regarding the Proposed Transaction as the ENLK Conflicts Committee determined to be appropriate.

        On October 21, 2018, the ENLK Conflicts Committee unanimously determined that the Merger Agreement and Transactions, including the Merger, are fair and reasonable to, and in the best interest of, ENLK and the ENLK Unaffiliated Unitholders, and unanimously approved the Merger Agreement, the other Transaction Documents, and the Transactions, including the Merger, which approval constituted "Special Approval" under the ENLK Partnership Agreement. The ENLK Conflicts Committee also recommended that the ENLK Board approve the Merger Agreement, the Transaction Documents, and the Transactions, including the Merger, and resolved, and recommended that the ENLK Board resolve, to recommend that the ENLK Voting Unitholders approve the Merger Agreement.

65


Table of Contents

        Later on October 21, 2018, the ENLK Board, acting upon the recommendation of the ENLK Conflicts Committee, unanimously (i) determined that the Merger Agreement, the other Transaction Documents, and the Transactions, including the Merger, are in the best interest of ENLK and the ENLK Unaffiliated Unitholders, (ii) approved the Merger Agreement, the other Transaction Documents, and the Transactions, and directed that the Merger Agreement be submitted to a vote of the ENLK Voting Unitholders, and (iii) determined to recommend that the ENLK Voting Unitholders approve the Merger Agreement.

        The ENLK Conflicts Committee consulted with its financial and legal advisors and considered many factors in making its determination and approvals, and the related recommendations to the ENLK Board and the ENLK Common Unitholders. The ENLK Conflicts Committee considered the following factors to be generally positive or favorable in making its determination and approvals, and the related recommendations to the ENLK Board and the ENLK Common Unitholders:

Table of Contents

        The foregoing discussion of the information and factors considered by the ENLK Conflicts Committee is not intended to be exhaustive, but includes material factors the committee considered. In view of the variety of factors considered in connection with its evaluation of the Transactions and the complexity of these matters, the ENLK Conflicts Committee did not find it useful and did not attempt to quantify or assign any relative or specific weights to the various factors considered in making its determination and recommendation. In addition, each of the members of the ENLK Conflicts Committee may have given differing weights to different factors. Overall, the ENLK Conflicts Committee believed that the positive factors supporting the Transactions outweighed the negative factors it considered.

Opinion of Evercore—Financial Advisor to the ENLK Conflicts Committee

        The ENLK Conflicts Committee retained Evercore to act as its financial advisor in connection with evaluating the proposed Merger. At the request of the ENLK Conflicts Committee, at a meeting of the ENLK Conflicts Committee held on October 21, 2018, Evercore rendered its oral opinion to the ENLK Conflicts Committee (subsequently confirmed in writing) that, as of October 21, 2018 and based upon and subject to the assumptions made, procedures followed, matters considered, and qualifications and limitations of the review undertaken by Evercore in rendering its opinion as set forth therein, the Exchange Ratio was fair, from a financial point of view, to the ENLK Unaffiliated Unitholders.

        The opinion speaks only as of the date it was delivered and not as of the time the Merger will be completed or any other date. The opinion does not reflect changes that may occur or may have occurred after October 21, 2018, which could alter the facts and circumstances on which Evercore's opinion was based. It is understood that subsequent developments or information of which Evercore is, or was, not aware may affect Evercore's opinion, but Evercore does not have any obligation to update, revise, or reaffirm its opinion.

        The full text of the written opinion of Evercore, which sets forth the assumptions made, procedures followed, matters considered, and qualifications and limitations of the review undertaken in rendering its opinion, is attached hereto as Annex G. You are urged to read Evercore's opinion carefully and in its entirety. Evercore's opinion was directed to the ENLK Conflicts Committee (in its capacity as such), and only addressed the fairness, from a financial point of view, as of October 21, 2018, to the ENLK Unaffiliated Unitholders of the Exchange Ratio. Evercore's opinion did not address any other term, aspect, or implication of the Merger. Neither Evercore's opinion, the summary of such

70

opinion, nor the related analyses set forth in this joint information statement/proxy statement/prospectus are intended to be, and they do not constitute, a recommendation to the ENLK Conflicts Committee, the ENLK Board, the ENLK Common Unitholders or any other persons in respect of the Merger, including as to how any ENLK Common Unitholder should vote or act in respect of the Merger or any other transaction. The summary of Evercore's opinion set forth in this joint information statement/proxy statement/prospectus is qualified in its entirety by reference to the full text of the written opinion.

        In connection with rendering its opinion, Evercore, among other things:

        For purposes of its analysis and opinion, Evercore assumed and relied upon, without undertaking any independent verification of, the accuracy and completeness of all of the information publicly available, and all of the information supplied or otherwise made available to, discussed with, or

71


Table of Contents

reviewed by Evercore, and Evercore assumed no liability therefor. With respect to the projected financial and operating data relating to ENLC and ENLK referred to above, Evercore assumed that they had been reasonably prepared on bases reflecting the best currently available estimates and good faith judgments of management of ENLC and ENLK, as applicable, as to the future financial performance of ENLC and ENLK under the assumptions reflected therein. Evercore expressed no view as to any projected financial or operating data or any judgments, estimates, or assumptions on which they were based.

        For purposes of rendering its opinion, Evercore assumed, in all respects material to its analysis, that the Merger Agreement would be executed and delivered (in the draft form reviewed by Evercore), that the representations and warranties of each party contained in the Merger Agreement (in the draft form reviewed by Evercore) were true and correct, that each party would perform all of the covenants and agreements required to be performed by it under the Merger Agreement and that all conditions to the consummation of the Merger would be satisfied without material waiver or modification thereof. Evercore assumed that any modification to the structure of the Merger would not vary in any respect material to its analysis. Evercore further assumed that all governmental, regulatory, or other consents, approvals, or releases necessary for the consummation of the Merger would be obtained without any material delay, limitation, restriction, or condition that would have an adverse effect on ENLC or ENLK or the consummation of the Merger or materially reduce the benefits of the Merger to ENLC, ENLK, or the ENLK Unaffiliated Unitholders. Evercore assumed that the final versions of all documents reviewed by it in draft form would not differ in any material respect from the drafts reviewed by it.

        Evercore did not make nor did it assume any responsibility for making any independent valuation or appraisal of any assets or liabilities of ENLC or ENLK, nor was Evercore furnished with any such appraisals, nor did it evaluate the solvency or fair value of ENLC or ENLK under any state or federal laws relating to bankruptcy, insolvency, or similar matters. Evercore's opinion was necessarily based upon information made available to it as of the date of its opinion and financial, economic, monetary, market, regulatory, and other conditions as they existed and as could be evaluated on the date thereof. The opinion noted that subsequent developments may affect Evercore's opinion and that Evercore does not have any obligation to update, revise, or reaffirm its opinion.

        Evercore was not asked to pass upon, and expressed no opinion with respect to, any matter other than the fairness, from a financial point of view, to the ENLK Unaffiliated Unitholders of the Exchange Ratio. Evercore did not express any view on, and its opinion did not address, the fairness of the Merger to, or any consideration received in connection therewith by, any other person or the holders of any other securities, creditors or other constituencies of ENLK, nor as to the fairness of the amount or nature of any compensation to be paid or payable to any of the officers, directors or employees of any party to the Merger Agreement, or any class of such persons, whether relative to the Exchange Ratio or otherwise. Evercore's opinion did not address the relative merits of the Merger as compared to other business or financial strategies that might be available to ENLK or ENLC, nor did it address the underlying business decision of ENLC or ENLK to engage in the Merger or use the Exchange Ratio. In arriving at its opinion, Evercore was not authorized to solicit, and did not solicit, interest from any third party with respect to the acquisition of any or all of the ENLK Common Units or any business combination or other extraordinary transaction involving ENLK. Evercore's opinion did not constitute a recommendation to the ENLK Conflicts Committee or any other persons in respect of the Merger, including as to how any ENLK Common Unitholder should vote or act in respect of the Merger. Evercore expressed no opinion as to the price at which the ENLK Common Units or ENLC Common Units will trade at any time. The opinion noted that Evercore is not a legal, regulatory, accounting, or tax expert and that Evercore assumed the accuracy and completeness of assessments by ENLC, ENLK and their advisors with respect to legal, regulatory, accounting, and tax matters.

Summary Financial Analyses

        Set forth below is a summary of the material financial analyses performed by Evercore and reviewed with the ENLK Conflicts Committee on October 21, 2018, in connection with rendering Evercore's opinion to the ENLK Conflicts Committee. Each analysis was provided to the ENLK Conflicts Committee. However, the following summary does not purport to be a complete description of the analyses performed by Evercore. In connection with arriving at its opinion, Evercore considered all of its analyses as a whole, and the order of the analyses described and the results of these analyses do not represent any relative importance or particular weight given to these analyses by Evercore. Except as otherwise noted, the following quantitative information, to the extent that it is based on market data, is based on market data (including the closing prices for the ENLK Common Units and ENLC Common Units) that existed on October 21, 2018, and is not necessarily indicative of current market conditions.

        The following summary of financial analyses includes information presented in tabular format. These tables must be read together with the text of each summary. The tables alone do not constitute a complete description of the financial analyses performed by Evercore. Considering the tables below without considering the full narrative description of the financial analyses, including the methodologies and assumptions underlying the analyses, could create a misleading or incomplete view of Evercore's financial analyses.

        Financial data for ENLC and ENLK utilized in the financial analyses described below were based on, among other things, financial projections of ENLC, on a standalone basis as prepared by the management of ENLC (which Evercore refers to in this section as the "ENLC forecast"), and financial projections of ENLK on a standalone basis, prepared by the management of ENLK (which Evercore refers to in this section as the "ENLK forecast").

        Evercore performed a series of analyses to derive indicative valuation ranges for ENLK Common Units and ENLC Common Units. Evercore subsequently utilized each of the resulting implied valuation ranges for ENLK and ENLC to derive a range of implied exchange ratios of ENLK Common Units to ENLC Common Units, and compared these ratios to the Exchange Ratio. The following is a summary of the material financial analyses performed by Evercore with respect to each of ENLC and ENLK in preparing Evercore's opinion:

        Evercore calculated the implied exchange ratio ranges reflected in the financial analyses described below by comparing (i) the low end of the valuation range for ENLK Common Units to the low end of the valuation range for ENLC Common Units and (ii) the high end of the valuation range for ENLK Common Units to the high end of the valuation range for ENLC Common Units. The resulting implied exchange ratio ranges were then compared with the Exchange Ratio.

        In addition, Evercore performed certain other analyses which were reviewed with the ENLK Conflicts Committee. As reference analyses, Evercore performed a discounted cash flow analysis for ENLK Common Units and a premiums paid analysis for ENLK Common Units and the Merger, as further described below.

Analysis of ENLK

        Evercore performed a discounted distribution analysis for the ENLK Common Units based on the present value of the future cash distributions to ENLK Common Unitholders. Evercore utilized a terminal yield range of 8.0% to 9.5% based on ENLK trading over the preceding 52 weeks. Evercore utilized a cost of equity of 9.5% to 11.5% based on a capital asset pricing model ("CAPM") analysis and a cost of equity of 10.0% to 14.0% based on total expected market return for the selected comparable partnerships listed under the heading "ENLK Peer Group Trading Analysis" below (the "Selected ENLK Peers"). Using the ENLK forecast and a cost of equity based on CAPM, Evercore determined an implied equity value per ENLK Common Unit range of $16.47 to $19.73. Using the ENLK forecast and a cost of equity based on total expected market return, Evercore determined an implied equity value per ENLC Common Unit range of $15.55 to $19.49.

        Evercore performed a peer group trading analysis of ENLK by reviewing and comparing the market values and trading multiples of the following publicly traded partnerships that Evercore deemed to have certain characteristics similar to those of ENLK:

        Although the Selected ENLK Peers were compared to ENLK for purposes of this analysis, no partnership used in the peer group analysis is identical or directly comparable to ENLK. In order to calculate peer group trading multiples, Evercore relied on publicly available filings with the SEC and equity research analyst estimates.

        For each of the Selected ENLK Peers, Evercore calculated the following trading multiples:

        Although the selected transactions were compared to the Merger for purposes of this analysis, no selected transaction used in the precedent M&A transaction analysis is identical or directly comparable to the Merger. Evercore reviewed the historical Enterprise Value to EBITDA observed in each of the selected transactions.

        The mean and median implied multiples of Enterprise Value to Current EBITDA are set forth below. The table also includes relevant multiple reference ranges selected by Evercore based on the resulting range of multiples and certain other considerations related to the specific characteristics of ENLK noted by Evercore.

        Evercore applied the relevant ranges of selected multiples to fiscal year 2018 EBITDA per the ENLK forecast. Evercore determined an implied equity value per ENLK Common Unit range of $11.87 to $18.09.

        The analyses and data described below were presented to the ENLK Conflicts Committee for informational and reference purposes only and did not provide the basis for, and were not otherwise material to, the rendering of Evercore's fairness opinion.

        Evercore performed a discounted cash flow analysis of ENLK by valuing the cash flows to be received by ENLK based on the ENLK forecast. Evercore calculated the value per ENLK Common Unit range by discounting, back to present value, ENLK's discrete unlevered free cash flows from January 1, 2019 through December 31, 2021, and estimated terminal values as of December 31, 2021, based on a range of estimated EBITDA exit multiples as well as perpetuity growth rates. Evercore selected a range of discount rates of 7.0% to 8.0% based on its professional judgment and expertise, including its analysis of the weighted average cost of capital for ENLK, taking into account a CAPM analysis for ENLK's cost of equity based on an analysis of characteristics of ENLK and the Selected ENLK Peers. Evercore selected a range of EBITDA exit multiples of 10.0x to 12.0x based on its professional judgment and expertise, taking into account relevant implied multiples of Enterprise Value to EBITDA of the Selected ENLK Peers, among other things. For the perpetuity growth rate assumption, Evercore selected a range of 1.75% to 2.25% based on its professional judgment and expertise, taking into consideration the long-term rate of inflation, among other factors. For both the EBITDA exit multiple approach and the perpetuity growth rate approach, Evercore calculated the implied equity value per ENLK Common Unit range.

        The Discounted Cash Flow Analysis utilizing the EBITDA exit multiple approach to calculate terminal value resulted in an implied equity value per ENLK Common Unit range of $14.49 to $20.08. The Discounted Cash Flow Analysis utilizing the perpetuity growth approach to calculate terminal value resulted in an implied equity value per ENLK Common Unit range of $14.39 to $22.90.

        Evercore compared the premiums implied by the Exchange Ratio with premiums received in selected related-party merger transactions where the target was an MLP or a limited liability company. Evercore calculated the implied premiums received considering the implied per LP unit or per share

        Evercore reviewed the relevant merger premiums and derived a range of premiums to ENLK's relevant ENLK Common Unit price as of October 19, 2018, of 6.0% to 12.0%. Evercore determined an implied equity value per ENLK Common Unit range of $19.36 to $20.45, which implied an implied exchange ratio range of 1.21x to 1.27x.

Analysis of ENLC

        Evercore performed a discounted distribution analysis of ENLC Common Units based on the present value of the future cash distributions to ENLC Unitholders. The projected distributions used by Evercore were based on the ENLC forecast, a terminal yield range of 6.0% to 7.5% based on ENLC's distribution yield range during the preceding 52 weeks, a cost of equity of 10.0% to 11.5% based on a CAPM analysis utilizing the selected comparable publicly traded general partners ("GPs") listed under the heading "ENLC Peer Group Trading Analysis" below (the "Selected ENLC Peers") and cost of equity of 18.0% to 22.0% based on the total expected market return utilizing the Selected ENLC Peers. Using the ENLC forecast and a cost of equity based on CAPM, Evercore determined an implied equity value per ENLC Common Unit range of $17.15 to $21.41. Using the ENLC forecast and a cost of equity based on total expected market return, Evercore determined an implied equity value per ENLC Common Unit range of $13.46 to $17.65.

        Evercore applied the selected Enterprise Value of GP to GP IDR Cash Flow multiple reference ranges to ENLC's GP and IDR cash flow and applied the selected Enterprise Value to EBITDA reference range to ENLC's EBITDA from its 16.1% interest in EOGP per the ENLC forecast for calendar year 2018 and calendar year 2019. In addition, Evercore utilized the valuation range from the ENLK Peer Group Trading Analysis to value ENLK Common Units owned by ENLC. Evercore determined an implied equity value per share range of $11.42 to $17.82.

        Evercore performed a valuation analysis of ENLC Common Units based on multiples of transaction value to run-rate GP IDR Cash Flow paid in historical transactions involving publicly traded general partners with controlling interest in the highest tier since January 1, 2016, that Evercore deemed relevant based on its experience in the midstream sector and in mergers and acquisitions involving publicly traded general partners and partnerships. The following list sets forth the transactions analyzed based on such characteristics:

        For each of the selected transactions, Evercore calculated and compared the Enterprise Value of the target as a multiple of the target's estimated Run-rate GP IDR cash flow. Evercore observed that the mean and median multiples of transaction value to run-rate GP IDR Cash Flow for the selected precedent transactions were 21.1x and 18.5x, respectively. Evercore derived a range of relevant implied multiples of transaction value to current calendar year GP IDR Cash Flow of 17.0x to 20.0x for its precedent transactions analysis and applied this range to estimated calendar year 2018 GP IDR Cash Flow per the ENLC forecast. Evercore determined the value of the asset EBITDA derived from ENLC's distributions from its 16.1% interest in EOGP using the selected transactions involving the acquisition of natural gas gathering and processing assets that Evercore deemed to have certain characteristics similar to those of ENLK's assets that were used to value the ENLK Common Units. In addition, Evercore utilized the valuation range from the ENLK Precedent M&A Transaction Analysis to value ENLK Common Units owned by ENLC. Evercore determined an implied equity value per ENLC Common Unit range of $13.29 to $17.78.

General

        The foregoing summary of certain material financial analyses does not purport to be a complete description of the analyses or data presented by Evercore. The ENLK Conflicts Committee selected Evercore to provide financial advice in connection with its evaluation of the proposed Merger because of, among other reasons, Evercore's experience, reputation, and familiarity with the industry and because its investment banking professionals have substantial experience in transactions similar to the Merger. In connection with the review of the Merger, Evercore performed a variety of financial and comparative analyses for purposes of rendering its opinion to the ENLK Conflicts Committee. The preparation of a fairness opinion is a complex process and is not necessarily susceptible to partial analysis or summary description. Selecting portions of the analyses or of the summary described above, without considering the analyses as a whole, could create an incomplete view of the processes underlying Evercore's opinion. In arriving at its fairness determination, Evercore considered the results of all the analyses and did not draw, in isolation, conclusions from or with regard to any one analysis or factor considered by it for purposes of its opinion. Rather, Evercore made its determination as to fairness on the basis of its experience and professional judgment after considering the results of all the analyses. In addition, Evercore may have given various analyses and factors more or less weight than other analyses and factors, may have deemed various assumptions more or less probable than other assumptions and, as described above, utilized certain assumptions and assessments provided by ENLK without independent analysis. As a result, the ranges of valuations resulting from any particular analysis or combination of analyses described above should not be taken to be the view of Evercore with respect to the actual value of the ENLK Common Units or ENLC Common Units. No company or partnership used in the above analyses as a comparison is directly comparable to ENLK or ENLC, and no precedent transaction used is directly comparable to the Merger. Furthermore, Evercore's analyses 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, partnerships or transactions used, including judgments and assumptions with regard to industry

performance, general business, economic, market, and financial conditions, and other matters, many of which are beyond the control of ENLK or ENLC or their affiliates and their respective advisors.

        Evercore prepared these analyses for the information and benefit of the ENLK Conflicts Committee (in its capacity as such) and for the purpose of providing an opinion to the ENLK Conflicts Committee as to the fairness of the Exchange Ratio, from a financial point of view, to the ENLK Unaffiliated Unitholders. These analyses do not purport to be appraisals or to necessarily reflect the prices at which the business or securities actually may be sold. Any estimates contained in these analyses are not necessarily indicative of actual future results, which may be significantly more or less favorable than those suggested by such estimates. Accordingly, estimates used in, and the results derived from, Evercore's analyses are inherently subject to substantial uncertainty, and Evercore assumes no responsibility if future results are materially different from those forecasted in such estimates. The issuance of the opinion was approved by an opinion committee of Evercore.

        Except as described above, the ENLK Conflicts Committee imposed no other restrictions or limitations on Evercore with respect to the investigations made or the procedures followed by Evercore in rendering its opinion. The Exchange Ratio was determined through arm's-length negotiations between the ENLK Conflicts Committee and ENLC Conflicts Committee, and the ENLK Conflicts Committee approved the Merger Agreement and recommended the Merger Agreement to the ENLK Board for approval. Evercore provided advice to the ENLK Conflicts Committee during these negotiations. Evercore did not, however, recommend any specific Exchange Ratio to the ENLK Conflicts Committee, the ENLK Board, or ENLK or recommend that any specific Exchange Ratio constituted the only appropriate consideration for the Merger. Evercore's opinion was only one of many factors considered by the ENLK Conflicts Committee in evaluating the Merger and making its recommendation to the ENLK Board, and the opinion should not be viewed as determinative of the views of the ENLK Conflicts Committee with respect to the Merger.

        Under the terms of Evercore's engagement letter with the ENLK Conflicts Committee, ENLK paid Evercore an initial fee of $250,000 upon execution of its engagement letter with the ENLK Conflicts Committee and a fee of $1,250,000 (against which the initial fee was credited) upon Evercore's rendering its opinion, which opinion fee was not contingent upon the conclusion reached in Evercore's opinion. Evercore will be entitled to receive an additional fee of $1,250,000 from ENLK upon consummation of the Merger. Evercore may also receive an additional advisory fee, subject to the sole discretion of the ENLK Conflicts Committee. In addition, ENLK has agreed to reimburse Evercore for its reasonable out-of-pocket expenses (including legal fees, expenses, and disbursements) incurred in connection with its engagement. Such expenses are not to exceed $75,000 without the prior consent of the ENLK Conflicts Committee. ENLK also agreed to indemnify Evercore and any of its members, partners, officers, directors, advisors, representatives, employees, agents, affiliates, and controlling persons, if any, against certain liabilities and expenses arising out of its engagement, or to contribute to payments which any of such persons might be required to make with respect to such liabilities.

        Evercore and its affiliates engage in a wide range of activities for their own accounts and the accounts of their respective customers. In the ordinary course of business, Evercore or its affiliates may actively trade the securities, or related derivative securities, or financial instruments of ENLK, ENLC, and their respective affiliates, for its own account and for the accounts of their respective customers and, accordingly, may at any time hold a long or short position in such securities or instruments.

        During the two-year period prior to October 21, 2018, no material relationship existed between Evercore and its affiliates and ENLK, ENLC or any of their respective affiliates, pursuant to which compensation was received by Evercore or its affiliates as a result of such a relationship. Evercore may provide financial or other services to ENLC, ENLK, or their respective affiliates in the future and in connection with any such services Evercore may receive compensation.

The Written Consent of Certain ENLC Unitholders

        Because ENLC Common Units are listed on the NYSE, ENLC is subject to NYSE rules and regulations. Section 312.03 of the NYSE Listed Company Manual requires unitholder approval prior to the issuance of common units, or securities convertible into or exercisable for common units, in any transaction or series of transactions if (i) the common units to be issued have, or will have upon issuance, voting power equal to or in excess of 20% of the voting power outstanding before the issuance of such common units or of securities convertible into or exercisable for common units, or (ii) the number of common units to be issued is, or will be upon issuance, equal to or in excess of 20% of the number of common units outstanding before the issuance of the common units or of securities convertible into or exercisable for common units.

        Upon completion of the Merger, the ENLC Common Units to be issued to ENLK Public Unitholders as consideration in the Merger would exceed 20% of both the voting power and number of ENLC Common Units outstanding before such issuance.

        As of October 21, 2018, ENLC had 181,294,967 ENLC Common Units issued and outstanding. Each ENLC Common Unit entitles its holder to one vote on each matter submitted to the ENLC Unitholders. As of the date of this joint information statement/proxy statement/prospectus, the ENLC Majority Holder was the record owner of approximately 63.7% of the total outstanding ENLC Common Units. Accordingly, the ENLC Majority Holder approved the ENLC Unit Issuance, which includes the issuance of all ENLC Common Units that are issuable as consideration in the Merger pursuant to the Merger Agreement, by executing the ENLC Written Consent.

        Because the ENLC Majority Holder, holding a majority of the outstanding ENLC Common Units as of the record date, consented to the ENLC Unit Issuance, no other unitholder votes, consents, or actions will be required or obtained in connection with this information statement or the ENLC Unit Issuance.

Unaudited Projected Financial Information

        EnLink does not, as a matter of course, publicly disclose long-term financial projections because of, among other reasons, the uncertainty of the underlying assumptions and estimates and the unpredictability of EnLink's business and competitive markets in which it operates. However, in connection with the evaluation of a potential transaction, EnLink management prepared and provided to the ENLC Board, the ENLC Conflicts Committee, the ENLK Board, and the ENLK Conflicts Committee certain internal projections (the "Projections") regarding the future financial performance of ENLC, ENLK, and Pro Forma ENLC with respect to 2018 through 2021. The Projections were used by the ENLC Board, the ENLC Conflicts Committee, the ENLK Board, and the ENLK Conflicts Committee for the purpose of evaluating the Transactions. The Projections also were provided to Barclays and Evercore for their use and reliance in connection with their respective financial analyses and opinions described in the sections entitled "—Opinion of Barclays—Financial Advisor to ENLC Conflicts Committee" and "—Opinion of Evercore—Financial Advisor to ENLK Conflicts Committee."

        A summary of the Projections is included below to give ENLC Unitholders and ENLK Unitholders access to certain unaudited projections that were made available on September 20, 2018 to the ENLC Board, the ENLC Conflicts Committee, the ENLK Board, the ENLK Conflicts Committee, and the ENLC Conflicts Committee's and the ENLK Conflicts Committee's respective advisors in connection with the Merger. EnLink management has not updated, and does not intend to update or otherwise revise, the Projections or the prospective financial information contained therein to reflect circumstances existing or arising since their preparation, including any changes in general economic or industry conditions, or to reflect the occurrence of unanticipated events. In particular, the Projections, based on the date on which they were made available to the EnLink Boards and the Conflicts Committees, assume an illustrative exchange ratio of 1.06 ENLC Common Units per ENLK Common

83


Table of Contents

Unit instead of the ultimate Exchange Ratio of 1.15 ENLC Common Units per ENLK Common Unit. The Projections and the prospective financial information contained therein do not necessarily reflect current estimates or assumptions that EnLink management may have about prospects for EnLink's business, changes in general business or economic conditions, or any other transaction, event, or circumstance that has occurred or that may occur and that was not anticipated, or that has occurred or that may occur differently than as anticipated, at the time the Projections or any of the prospective financial information contained therein were prepared.

        You should be aware that uncertainties are inherent in projections of any kind. None of ENLC, ENLK, or any of their respective affiliates, officers, directors, advisors, or other representatives has made or makes any representation or can give any assurance to any ENLC Unitholder or ENLK Unitholder regarding the ultimate performance of ENLC or ENLK compared to the summarized information set forth below or that any projected results will be achieved.

        The inclusion of the following Projections in this joint information statement/proxy statement/prospectus should not be regarded as an indication that ENLC, ENLK, or their respective advisors or other representatives considered or consider the Projections to be necessarily indicative of actual future performance or events, and the Projections set forth below should not be relied upon as such. Accordingly, ENLC Unitholders and ENLK Unitholders are cautioned not to place undue reliance on the Projections.

        The accompanying prospective financial information was not prepared with a view toward public disclosure or toward compliance with GAAP, the published guidelines of the SEC regarding projections or the use of non-GAAP financial measures, or the guidelines established by the American Institute of Certified Public Accountants for preparation or presentation of prospective financial information. In the view of EnLink management, the Projections were prepared on a reasonable basis, reflected the best available estimates and judgments based on the facts and circumstances existing at the time such projections were prepared, and presented, to the best of the knowledge and belief of EnLink's management, the expected future financial performance of (i) each of ENLC and ENLK on a stand-alone basis if the Transactions were not consummated and (ii) Pro Forma ENLC, giving effect to the Transactions as if they occurred on January 1, 2019.

        The Projections and the prospective financial information contained therein included in this joint information statement/proxy statement/prospectus have been prepared by, and are the responsibility of, EnLink. Neither KPMG LLP ("KPMG"), nor any other independent accountants, have audited, reviewed compiled, examined, or performed any procedures or any other form of assurance with respect thereto, nor have they expressed any opinion or any other form of assurance on such information or its achievability, and they assume no responsibility for, and disclaim any association with, the Projections and the prospective financial information contained therein. The KPMG reports incorporated by reference into this joint information statement/proxy statement/prospectus relate to historical financial information of ENLC and ENLK, respectively. Such reports do not extend to the prospective financial information and should not be read to do so.

        While presented with numerical specificity, the Projections reflect numerous estimates and assumptions made by EnLink management with respect to industry performance and competition, general business, economic, market, and financial conditions and matters specific to each of ENLC's and ENLK's businesses, all of which are difficult to predict and many of which are beyond ENLC's and ENLK's control. In developing the Projections, EnLink management made numerous material assumptions with respect to ENLC, ENLK, and the pro forma company for the periods covered by such Projections, including:

Table of Contents

        The summaries of the Projections provided to the ENLC Board, the ENLC Conflicts Committee, the ENLK Board, and the ENLK Conflicts Committee are not included in this joint information statement/proxy statement/prospectus in order to induce any ENLK Unitholder to vote in favor of any of the proposals at the ENLK Unitholder Meeting. By including in this joint information statement/proxy statement/prospectus a summary of certain of the Projections, none of ENLC, ENLK, or any of their respective advisors or other representatives have made or are making any representation to any person regarding the ultimate performance of ENLC, ENLK, or Pro Forma ENLC. The Projections cover multiple years and such information by its nature becomes less predictive with each succeeding year.

        The following table sets forth a summary of the Projections with respect to ENLC and ENLK for 2018 through 2021, and with respect to Pro Forma ENLC for 2019 through 2021:

        We define adjusted EBITDA as net income (loss) plus (i) interest expense, (ii) provision (benefit) for income taxes, (iii) depreciation and amortization expense, (iv) impairments, (v) unit-based compensation, (vi) (gain) loss on non-cash derivatives, (vii) (gain) loss on disposition of assets, (viii) (gain) loss on extinguishment of debt, (ix) successful acquisition transaction costs, (x) accretion expense associated with asset retirement obligations, (xi) reimbursed employee costs, (xii) non-cash rent, (xiii) cash collections under the secured term loan receivable, and (xiv) distributions from unconsolidated affiliate investments, less (a) payments under onerous performance obligations, (b) non-controlling interest, (c) (income) loss from unconsolidated affiliate investments, and (d) non-cash revenue from contract restructuring.

        We define distributable cash flow (DCF) as adjusted EBITDA, less (i) interest expense, (ii) litigation settlement adjustment, (iii) adjustments for the redeemable non-controlling interest, (iv) interest rate swaps, (v) current income taxes and other non-distributable cash flows, (vi) accrued cash distributions on ENLK Series B Units and ENLK Series C Units paid or expected to be paid, and (vii) maintenance capital expenditures, excluding maintenance capital expenditures that were contributed by other entities and relate to the non-controlling interest of consolidated entities.

        We define cash available for distribution (CAD) as net income (loss) of ENLC less the net income (loss) attributable to ENLK, which is consolidated into ENLC's net income (loss), plus ENLC's (i) share of distributions from ENLK, (ii) share of EOGP's non-cash expenses, (iii) deferred income tax expense (benefit), (iv) corporate goodwill impairment, if any, and (v) successful acquisition transaction costs, if any, less ENLC's interest in maintenance capital expenditures of EOGP, and less third-party non-controlling interest share of net income (loss) from consolidated entities.

Accounting Treatment

        The Merger will be accounted for in accordance with Financial Accounting Standards Board Accounting Standards Codification 810, Consolidation. As ENLC controls ENLK and will continue to control ENLK after the Merger, the changes in ENLC's ownership interests in ENLK will be accounted for as an equity transaction and no gain or loss on the Merger will be recognized in ENLC's consolidated statements of operations.

No Dissenters' or Appraisal Rights

        Under the Delaware LP Act and the ENLK Partnership Agreement, there are no dissenters' or appraisal rights for the ENLK Unitholders with respect to the Transactions.

Listing of ENLC Common Units to be Issued in the Merger; Delisting and Deregistration of ENLK Common Units

        ENLC expects to obtain approval to list on the NYSE the ENLC Common Units to be issued pursuant to the Merger Agreement, which approval (subject to official notice of issuance) is a condition to closing the Merger. Upon completion of the Transactions, ENLK Common Units currently listed on the NYSE will cease to be listed on the NYSE and will be subsequently deregistered under the Exchange Act.

Regulatory Approvals Required for the Merger

        In order to consummate the Transactions, a filing must be made under the HSR Act and the rules promulgated thereunder by the FTC, and the waiting period, and any extension thereof, must have expired or been terminated. During the waiting period, and any extension thereof, the FTC and the DOJ may request additional information or take such action under the antitrust laws as the agencies deem necessary or desirable in the public interest, including seeking to enjoin the completion of the Transactions. ENLK and GIP Stetson II filed the requisite HSR Act notification forms on November 2, 2018, and early termination of the waiting period was granted on November 14, 2018. There are no other federal or state regulatory requirements that must be complied with or approvals that must be obtained in connection with the Transactions.

INFORMATION ABOUT THE ENLK UNITHOLDER MEETING AND VOTING

Date, Time, and Place

        The ENLK Unitholder Meeting will be held on January 23, 2019, at 10.00 a.m., Central Time, located at 1722 Routh Street, First Floor Conference Center, Dallas, Texas 75201. The meeting may be adjourned or postponed by EGP to another date or place for proper purposes, including for the purpose of soliciting additional proxies.

Purpose

        The ENLK Voting Unitholders will be asked to consider and vote upon the ENLK Merger Proposal and the ENLK Adjournment Proposal.

        ENLK will transact no other business at the ENLK Unitholder Meeting except such business as may properly be brought before the ENLK Unitholder Meeting or any adjournments or postponements thereof. At this time, ENLK knows of no other matters that will be presented for the consideration of the ENLK Voting Unitholders at the ENLK Unitholder Meeting.

Record Date and Quorum Requirement

        EGP has fixed December 18, 2018, as the record date for the ENLK Unitholder Meeting. ENLK Voting Unitholders at the close of business on the record date may vote at the ENLK Unitholder Meeting. We are commencing our solicitation of proxies on or about December 10, 2018, which is before the record date of December 18, 2018. We will continue to solicit proxies until the January 23, 2019 ENLK Unitholder Meeting. Each ENLK Voting Unitholder of record on December 18, 2018 who has not yet received a joint information statement/proxy statement/prospectus prior to that date will receive a joint information statement/proxy statement/prospectus and have the opportunity to vote on the matters described in the joint information statement/proxy statement/prospectus. Proxies delivered prior to the record date will be valid and effective so long as the ENLK Voting Unitholder providing the proxy is a holder of record on December 18, 2018, the record date. If you are not a holder of record on the record date, any proxy you deliver will be invalid and will not be counted at the ENLK Unitholder Meeting. If you deliver a proxy prior to the record date and remain a holder on the record date, you do not need to deliver another proxy after the record date. If you deliver a proxy prior to the record date and do not revoke that proxy, your proxy will be deemed to cover the number of ENLK Voting Units you own on the record date even if that number is different from the number of ENLK Voting Units you owned when you executed and delivered your proxy. Proxies received from persons who are not holders of record on the record date will not be effective. ENLK Voting Unitholders may cast one vote for each ENLK Voting Unit that the ENLK Voting Unitholder owned as of the close of business on the record date. Votes may be cast at the ENLK Unitholder Meeting in person or by proxy.

        The presence, in person or by proxy, at the ENLK Unitholder Meeting of a majority of the ENLK Voting Units, as of the record date, will constitute a quorum and will permit ENLK to conduct the proposed business at the ENLK Unitholder Meeting. ENLK Voting Units will be counted as present at the ENLK Unitholder Meeting if the ENLK Voting Unitholder is present in person at the meeting or has submitted and not revoked a properly executed proxy card or properly submitted and not revoked a proxy via telephone or the Internet. Proxies received but marked as abstentions will be counted as units that are present and entitled to vote for purposes of determining the presence of a quorum. A broker non-vote will also be considered present at the meeting for purposes of determining the presence of a quorum but cannot be included in the vote. Abstentions and broker non-votes have the same effect as a vote against the merger for purposes of the vote required to approve the ENLK Merger Proposal and the ENLK Adjournment Proposal.

Submitting a Proxy Card

        ENLK Voting Unitholders holding ENLK Voting Units in their own name may submit their proxy by completing, signing, dating, and mailing the enclosed proxy card in the enclosed postage-prepaid envelope. Submitting a proxy by this method will not affect your right to attend the ENLK Unitholder Meeting.

        ENLK Voting Unitholders holding ENLK Voting Units in "street name" by a bank, broker, or other nominee should follow the separate voting procedures, if any, provided by the bank, broker, or other nominee with this proxy statement.

Submitting a Proxy via Telephone or Internet

        Submitting a proxy via telephone or the Internet is fast and convenient. ENLK Voting Unitholders holding ENLK Voting Units in their own name who choose to submit their proxy via telephone or the Internet should follow the instructions set forth on the enclosed proxy card. The telephone and Internet proxy procedures are designed to authenticate proxies by use of a personal control number, which appears on the proxy card. These procedures, which comply with Delaware law, allow you to appoint a proxy to vote your ENLK Voting Units and to confirm that your instructions have been properly recorded. If you submit your proxy via telephone or the Internet, you do not have to mail in your proxy card, but your proxy must be received by 11:59 p.m., Central Time, on January 22, 2019, which may be extended in the sole discretion of EGP.

        ENLK Voting Unitholders holding ENLK Voting Units in "street name" by a bank, broker, or other nominee should follow the instructions provided with the proxy materials to determine if Internet or telephone proxy submission is available. If your bank, broker, or other nominee does make Internet or telephone proxy submission available, please follow the instructions provided on the voting form supplied by your bank, broker, or other nominee.

Revoking Your Proxy

        If your ENLK Voting Units are registered directly in your name with the transfer agent, you may revoke your proxy at any time before it is voted at the ENLK Unitholder Meeting by:

        If your ENLK Voting Units are held through a bank, broker, or other nominee, you should follow the instructions of your bank, broker, or other nominee regarding the revocation of proxies. If your bank, broker, or other nominee allows you to submit your proxy via telephone or Internet, you may be able to change your proxy by submitting a proxy again by telephone or Internet.

Questions and Additional Information

Voting at the ENLK Unitholder Meeting

        Submitting a proxy now will not limit your right to vote at the ENLK Unitholder Meeting if you decide to attend in person. If you plan to attend the ENLK Unitholder Meeting and wish to vote in person, you will be given a ballot at the ENLK Unitholder Meeting. Please note, however, that if your ENLK Voting Units are held in "street name" by a bank, broker, or other nominee, and you wish to vote at the ENLK Unitholder Meeting, you must bring to the ENLK Unitholder Meeting a proxy from the bank, broker, or other nominee authorizing you to vote at the ENLK Unitholder Meeting. Please contact your bank, broker, or other nominee for specific instructions.

Vote Required; How ENLK Common Units are Voted

        Pursuant to the ENLK Partnership Agreement, holders of a majority of the outstanding ENLK Voting Units, voting as a single class, must affirmatively vote in favor of the ENLK Merger Proposal in order for it to be approved. Failures to vote, in addition to abstentions and broker non-votes, will have the same effect as a vote against the ENLK Merger Proposal for purposes of the vote required under the Merger Agreement and the ENLK Partnership Agreement.

        Pursuant to the ENLK Partnership Agreement, if a quorum is present at the ENLK Unitholder Meeting, holders of a majority of the ENLK Voting Units issued and outstanding and entitled to vote must affirmatively vote in favor of the ENLK Adjournment Proposal in order for it to be approved. If a quorum is not present, the ENLK Adjournment Proposal requires approval by the affirmative vote of holders of a majority of the outstanding ENLK Voting Units represented either in person or by proxy at the ENLK Unitholder Meeting.

        If you have timely and properly submitted your proxy, clearly indicated your vote, and have not revoked your proxy, your ENLK Voting Units will be voted as indicated on your proxy.

        If any other matters are properly presented for consideration at the ENLK Unitholder Meeting or any adjournment or postponement thereof, the persons named in the proxy will have the discretion to vote on these matters.

Units Beneficially Owned by EGP Directors and Officers

        EGP's directors and executive officers beneficially owned 1,385,231 ENLK Common Units on December 4, 2018. These ENLK Voting Units represent in total less than 0.4% percent of the total voting power of the ENLK Voting Units outstanding as of such date. ENLK currently expects that EGP's directors and executive officers will vote their ENLK Voting Units in favor of all the proposals to be voted on at the ENLK Unitholder Meeting, although none of them has entered into any agreements obligating them to do so.

Proxy Solicitation

        This proxy statement is being furnished in connection with the solicitation of proxies by EGP on behalf of the ENLK Board. The expenses of such solicitation, including the expenses of preparing, printing, and mailing the proxy statement and materials used in the solicitation, will be borne 50% by ENLC and 50% by ENLK. In addition to the mailing of this joint information statement/proxy statement/prospectus, the directors, executive officers and employees of EGP or its Affiliates may also, without compensation other than their regular compensation, solicit proxies by mail, telephone, e-mail, the Internet, facsimile, or personal conversation. ENLK may also reimburse brokers, custodians, nominees, fiduciaries, and others for expenses incurred in forwarding proxy materials to the beneficial owners of ENLK Voting Units.

Table of Contents

Adjournment

        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 ENLK 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 ENLK Common Units entitled to vote at such meeting and represented thereat either in person or by proxy. ENLK is not required to notify ENLK 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, ENLK 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 ENLK Voting Unitholders for use at the ENLK Unitholder Meeting will be used at any adjournment or postponement of the meeting.

THE ENLK PROPOSALS

Proposal 1. The ENLK Merger Proposal

        (Item 1 of ENLK's Proxy Card)

        In the ENLK Merger Proposal, ENLK is asking the ENLK Voting Unitholders to approve the Merger Agreement. Approval of the Merger Agreement by the ENLK Voting Unitholders is required for completion of the Merger.

        THE ENLK CONFLICTS COMMITTEE AND THE ENLK BOARD EACH UNANIMOUSLY RECOMMENDS A VOTE "FOR" THE MERGER PROPOSAL (ITEM 1 ON ENLK'S PROXY CARD).

Proposal 2. The ENLK Adjournment Proposal

        (Item 2 of ENLK's Proxy Card)

        The ENLK Unitholder Meeting may be adjourned to another time or place from time to time, if necessary or appropriate, to permit further solicitation of proxies in the event there are not sufficient votes at the time of the ENLK Unitholder Meeting to approve the ENLK Merger Proposal.

        If, at the ENLK Unitholder Meeting, the number of ENLK Voting Units present or represented and voting in favor of the ENLK Merger Proposal is insufficient to approve the ENLK Merger Proposal, ENLK intends to adjourn the ENLK Unitholder Meeting from time to time in order to enable the ENLK Board to solicit additional proxies.

        In the ENLK Adjournment Proposal, ENLK is asking the ENLK Voting Unitholders to authorize the holder of any proxy solicited by the ENLK Board to vote in favor of granting authority to the proxy holders, each of them individually, to adjourn the ENLK Unitholder Meeting to another time and place from time to time for the purpose of soliciting additional proxies. If the ENLK Voting Unitholders approve the ENLK Adjournment Proposal, ENLK could adjourn the ENLK Unitholder Meeting and any adjourned session of the ENLK Unitholder Meeting and use the additional time to solicit additional proxies, including the solicitation of proxies from ENLK Voting Unitholders who have previously voted.

        THE ENLK BOARD OF DIRECTORS UNANIMOULSY RECOMMENDS A VOTE "FOR" THE ENLK ADJOURNMENT PROPOSAL (ITEM 2 ON ENLK'S PROXY CARD).

OTHER MATTERS

Other Matters for Action at the ENLK Unitholder Meeting

        As of the date of this joint information statement/proxy statement/prospectus, the ENLK Board knows of no other matters that will be presented for consideration at the ENLK Unitholder Meeting other than as described in this joint information statement/proxy statement/prospectus.

        In accordance with the ENLK Partnership Agreement and Delaware law, business transacted at the ENLK Unitholder Meeting will be limited to those matters set forth in the notice of special meeting or matters otherwise properly presented by EGP at the ENLK Unitholder Meeting. If any other matters are properly presented at the ENLK Unitholder Meeting, or any adjournments of the special meeting, and are voted upon, including matters incident to the conduct of the meeting, the enclosed proxy will confer discretionary authority on the individuals named as proxy to vote the units represented by proxy as to any other matters so long as the ENLK Board is not aware of any such other matter a reasonable time before the ENLK Unitholder Meeting. It is intended that the persons named in the enclosed proxy and acting thereunder will vote in accordance with their best judgment on any such matter.

Householding of Joint Information Statement/Proxy Statement/Prospectus

        The SEC has adopted rules that permit companies and intermediaries (such as brokers or banks) to satisfy the delivery requirements for proxy statements with respect to two or more security holders sharing the same address by delivering a single notice or proxy statement addressed to those security holders. This process, which is commonly referred to as "householding," potentially provides extra convenience for security holders and cost savings for companies.

        As indicated in the notice provided by these banks, brokers, and other nominees to ENLK Voting Unitholders or ENLC Unitholders, as applicable, a single copy of this joint information statement/proxy statement/prospectus will be delivered to multiple ENLK Voting Unitholders or ENLC Unitholders, as applicable, sharing an address unless contrary instructions have been received from an affected ENLK Voting Unitholder or ENLC Unitholder, as applicable. Once you have received notice from your bank, broker, or other nominee that it will be "householding" communications to your address, "householding" will continue until you are notified otherwise or until you revoke your consent. If, at any time, you would prefer to receive separate copies of the joint information statement/proxy statement/prospectus either now or in the future, please contact your bank, broker, or other nominee, or contact ENLK or ENLC by written or oral request to ENLK or ENLC, as applicable, at 1722 Routh Street, Suite 1300, Dallas, Texas 75201 or by telephone at 214-953-9500, or, if you are an ENLK Voting Unitholder, contact MacKenzie Partners, Inc., ENLK's proxy solicitor.

THE MERGER AGREEMENT

        The following is a summary of the material terms of the Merger Agreement. The provisions of the Merger Agreement are extensive and not easily summarized. The following summary does not purport to be complete and is qualified in its entirety by reference to the Merger Agreement, a copy of which is attached to this joint information statement/proxy statement/prospectus as Annex A and is incorporated into this joint information statement/proxy statement/prospectus by reference. You should read carefully the Merger Agreement in its entirety because it, and not this joint information statement/proxy statement/prospectus, is the legal document that governs the terms of the Transactions.

        The Merger Agreement and this summary of its terms have been included to provide you with information regarding the terms of the Merger Agreement. They are not intended to provide any other factual information about ENLC, EMM, Merger Sub, ENLK, or EGP, or their respective subsidiaries or affiliates or equity holders.

        In addition, the Merger Agreement requires EGP to, and to cause ENLK and its subsidiaries to, and to use its reasonable best efforts to cause EGP's, ENLK's, and ENLK's subsidiaries' directors, officers, employees, counsel, investment bankers, financial advisors, and other representatives to, (a) immediately cease and cause to be terminated any discussions or negotiations with any persons conducted prior to the execution of the Merger Agreement regarding an acquisition proposal, and (b) immediately prohibit any access by any persons (other than members of the ENLC Group and their respective directors, officers, employees, counsel, investment bankers, financial advisors, and other representatives) to any confidential information relating to an acquisition proposal.

        If EGP, any member of the ENLK Group, or any of their respective directors, officers, employees, counsel, investment bankers, financial advisors, or other representatives receives an unsolicited, written, bona fide acquisition proposal that was not received or obtained in material violation of the "no solicitation" restrictions, EGP will, or will cause such person to, promptly deliver such acquisition proposal to the ENLK Board and the ENLK Conflicts Committee.

        For the purposes of the Merger Agreement, the term "acquisition proposal" means any inquiry, proposal, or offer from, or indication of interest in seeking a proposal or offer by, any person or "group" (as defined in Section 13(d) of the Exchange Act), other than any member of the ENLC Group or its affiliates, relating to any (a) direct or indirect acquisition (whether in a single transaction or a series of related transactions) of (i) assets of the ENLK Group equal to 20% or more of the consolidated assets of the ENLK Group as of June 30, 2018 or (ii) assets representing 20% or more of the Adjusted EBITDA (as defined in ENLK's Annual Report on Form 10-K for the year ended December 31, 2017) of the ENLK Group on a consolidated basis for the year ended December 31, 2017, in each case, as reported in ENLK's Annual Report on Form 10-K for the year ended December 31, 2017, (b) direct or indirect acquisition (whether in a single transaction or a series of related transactions) of beneficial ownership (within the meaning of Section 13(d) of the Exchange Act) of 20% or more of any class of equity interests in ENLK, whether through a tender offer, exchange offer, merger, consolidation, unit exchange, share exchange, business combination, recapitalization, liquidation, dissolution, or other similar transaction; provided that an inquiry, proposal, or offer involving the direct or indirect acquisition of beneficial ownership of (x) equity interests of ENLC not involving the direct acquisition of equity interests in ENLK, (y) equity interests of ENLK held by GIP Stetson I, Acacia, or EMI, or (z) ENLK Series B Units, ENLK Series C Units, or ENLK Common Units issued to the ENLK Series B Unitholders upon conversion thereof shall not constitute an "acquisition proposal."

        Notwithstanding these restrictions, the Merger Agreement provides that, at any time prior to obtaining the ENLK Unitholder Approval, EGP, for and on behalf of ENLK, may furnish any information to or enter into or participate in discussions or negotiations with, any person that makes an unsolicited, written, bona fide acquisition proposal that was not received or obtained in material violation of the "no solicitation" restrictions (such person making such proposal, a "receiving party") if:
