PRO FORMA CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

Introduction

At the effective time of the merger (the “Merger”) of NOLA Merger Sub, LLC (“Merger Sub”), a wholly-owned subsidiary of EnLink Midstream, LLC (“ENLC”), with and into EnLink Midstream Partners, LP (“ENLK”), with ENLK surviving the Merger as a subsidiary of ENLC, each issued and outstanding common unit representing a limited partner interest in ENLK (an “ENLK common unit”), other than the 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 common units representing limited liability company interests in ENLC (“ENLC common units”).

The unaudited pro forma condensed consolidated balance sheet gives effect to the Merger as if it had occurred on September 30, 2018; the unaudited pro forma condensed consolidated statements of operations give effect to the Merger as if it had occurred on January 1, 2017. The unaudited pro forma condensed consolidated balance sheet and condensed consolidated statements of operations should be read in conjunction with (i) ENLC’s Annual Report on Form 10-K for the year ended December 31, 2017, as filed with the Securities and Exchange Commission (the “SEC”) on February 21, 2018, (ii) ENLC’s Quarterly Report on Form 10-Q for the three months ended September 30, 2018, as filed with the SEC on November 7, 2018, (iii) ENLK’s Annual Report on Form 10-K for the year ended December 31, 2017, as filed with the SEC on February 21, 2018, and (iv) ENLK’s Quarterly Report on Form 10-Q for the three months ended September 30, 2018, as filed with the SEC on November 7, 2018.

The unaudited pro forma condensed consolidated financial statements are for illustrative purposes only and are not necessarily indicative of the financial results that would have occurred if the Merger had been consummated on the dates indicated, nor are they necessarily indicative of the financial position or results of operations in the future. The pro forma adjustments, as described in the accompanying notes, are based upon available information and certain assumptions that are believed to be reasonable as of December 31, 2018.

Notes to Unaudited Pro Forma Financial Information

Pro Forma Adjustments

Following is a description of the pro forma adjustments made to the historical financial statements of ENLC:

(a) Represents estimated transaction costs of $20 million of advisory and legal services, and other expenses expected to be paid in connection with the Merger. Such fees and expenses will be recognized in the statement of operations when incurred; however, the estimated expenses are not reflected in the pro forma statements of operations included herein.

(b) Represents the allocation of net income from non-controlling interests related to ENLK net income attributable to ENLC due to ENLC’s acquisition of the ENLK Public Units. The remaining pro forma net income from non-controlling interests represents net income allocated to the Series B Cumulative Convertible Preferred Units representing limited partner interests in ENLK, the Series C Fixed-to-Floating Rate Cumulative Redeemable Perpetual Preferred Units representing limited partner interests in ENLK, NGP Natural Resources XI, LP’s 49.9% share of net income from Delaware G&P LLC, and Marathon Petroleum Corporation’s 50% share of net income from Ascension Pipeline Company, LLC.

(c) Represents estimated income tax expense using ENLC’s statutory federal and blended state income tax rate of 23.5% due to additional net income allocated from ENLK to ENLC (per (b) above).

(d) Pro forma weighted average common units outstanding reflects (i) ENLC’s weighted average common units outstanding for the respective periods, plus (ii) the assumed conversion of ENLK Public Units into ENLC common units, based on the sum of the weighted average of ENLK common units outstanding during the respective periods less ENLK common units owned by ENLC, multiplied by the Exchange Ratio of 1.15 ENLC common units for each ENLK Public Unit. Pro forma diluted weighted average common units outstanding reflects the dilutive impact of non-vested restricted units currently outstanding under the long-term

incentive plans of ENLK and ENLC. A summary of weighted average units outstanding (in millions):

	Nine months ended September 30, 2018			Year Ended December 31, 2017
ENLC historical weighted average common units			181.1			180.5
ENLK weighted average common units outstanding	350.7			346.9
Less: ENLK common units owned by ENLC	(88.5	)		(88.5	)
ENLK Public Units converted to ENLC common units	262.2			258.4
Exchange Ratio units	1.15			1.15
ENLC common units issued for ENLK Public Units			301.5			297.2
Pro forma basic weighted average number of common units outstanding			482.6			477.7
Dilutive effect of non-vested ENLC restricted units			1.1			1.3
Dilutive effect of non-vested ENLK restricted units converted to ENLC restricted units			1.7			1.6
Pro forma diluted weighted average number of ENLC common units outstanding			485.4			480.6

(e) Represents the conversion of ENLK Public Units into ENLC common units.

(f) Reflects the estimated impact on deferred income taxes resulting from the Merger using ENLC’s statutory federal and state tax rate of 23.5 percent. The deferred income tax impact reflects a net adjustment of $693.8 million to deferred income taxes, resulting in a reduction of deferred tax liabilities of $361.8 million and a deferred tax asset of $332.0 million. The deferred income tax impact primarily relates to the effects of the change in ownership and the related increase in the depreciable and amortizable basis in ENLK’s assets for tax purposes, which is based on the closing price of $16.05 for ENLC common units on October 19, 2018 and the ENLC common units to be issued for ENLK Public Units based on ENLK’s common units outstanding as of September 30, 2018.
