On December 20, 2022, EnLink Midstream, LLC (the “Company”) and each of GIP III Stetson I, L.P. and GIP III Stetson II, L.P. (together “GIP Entities”), the holders of approximately 41.5%, in the aggregate, of the outstanding common units of the Company (the “Common Units”) and, in the case of GIP III Stetson I, L.P., the owner of all of the equity interests in EnLink Midstream Manager, LLC, the managing member of the Company (the “Manager”), entered into a Unit Repurchase Agreement (the “Repurchase Agreement”) pursuant to which the Company agreed to repurchase, on a quarterly basis, a number of Common Units held by the GIP Entities (the “GIP Units”) based upon the number of Common Units repurchased from public unitholders by the Company during the applicable quarter under the Company’s 2023 common unit repurchase program, as described below. The Repurchase Agreement is substantially similar to the repurchase agreement entered into by the Company and the GIP Entities on February 15, 2022, which provided for proportional repurchases by the Company of GIP Units during 2022, and which agreement will terminate as of December 31, 2022 in accordance with its terms.

Under the Repurchase Agreement, following each fiscal quarter beginning with the quarter ending March 31, 2023, the Company will repurchase from the GIP Entities a number of GIP Units equal to (i) the aggregate number of Common Units repurchased by the Company in the open market during such quarter, multiplied by (ii) a percentage such that the GIP Entities’ then-existing economic ownership percentage of outstanding Common Units is maintained after the open market repurchases are taken into account. The initial percentage will be adjusted each quarter, as necessary, so that the GIP Entities’ economic ownership interest will remain the same after giving effect to the open market repurchases. The per unit price the Company will pay for the GIP Units will be the average per unit price paid by the Company for the Common Units repurchased from public unitholders during the applicable quarter.

The repurchase of GIP Units by the Company will occur one business day before the Company’s reporting of earnings for such quarter. The Company will disclose in its periodic reports filed with the Commission the number of GIP Units purchased by the Company with respect to each quarter.

The Repurchase Agreement will terminate on the earlier of the date (1) on which the authorized funds under the Company’s 2023 common unit repurchase program have been expended, including funds applied to repurchases under the Repurchase Agreement, (2) on December 31, 2023, or (3) otherwise upon the mutual agreement of the parties thereto. The terms of the Repurchase Agreement were unanimously approved by the Manager’s Board of Directors (the “Board”) and, based upon the related party nature of the Repurchase Agreement with the GIP Entities, the Conflicts Committee of the Board.

The foregoing description of the Repurchase Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Repurchase Agreement, a copy of which is filed as Exhibit 10.1 to this report and is incorporated herein by reference.

The Board has authorized a common unit repurchase program for the repurchase of up to $200.0 million of outstanding Common Units during 2023. Repurchases under the common unit repurchase program will be made in accordance with applicable securities laws, from time to time in open market or private transactions and may be made pursuant to a trading plan meeting the requirements of 10b5-1 under the Securities Exchange Act of 1934, as amended. The repurchases will depend on market conditions and may be discontinued at any time.
