Class A Acquiror directly holds 21,751,018 Class A Shares.

Up-C Acquiror 1 directly holds 98,067,182 Class B Shares and a corresponding number of TE Units, and Up-C Acquiror 2 directly holds 2,587,939 Class B Shares and a corresponding number of TE Units.

Secondary Acquiror 1 directly holds 773,510 Class A Shares, and Secondary Acquiror 2 directly holds 1,127,935 Class A Shares.

Holdings Manager is the general partner of each of the Up-C Acquirors, Class A Acquiror and each of the Prairie Secondary Acquirors. Pursuant to the Equityholders Agreement, the consent of Enagás Holding and Enagas USA is required in certain circumstances for Holdings Manager to direct the voting and disposition of the securities held the Acquirors. Enagás is the sole shareholder of Enagás Internacional, which is the sole shareholder of Enagás Holding, which is the sole member of Enagas USA. As a result, each of the Reporting Persons may be deemed to beneficially own the Class A Shares, Class B Shares and TE Units held by the Acquirors. Enagás is a publicly traded corporation with shares listed on the Madrid, Barcelona, Bilbao and Valencia Stock Exchanges (Spain).

Neither the filing of this Schedule 13D nor any of its contents shall be deemed to constitute an admission that any of the Reporting Persons is the beneficial owner of the Class A Shares referred to herein for purposes of Section 13(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or for any other purpose, and such beneficial ownership is expressly disclaimed. Each Reporting Person expressly disclaims beneficial ownership of such Class A Shares and any assertion or presumption that it or he and the other persons on whose behalf this Schedule 13D is filed constitute a “group.”

By virtue of the Equityholders Agreement, dated March 11, 2019 (the “Equityholders Agreement”), by and among certain of the Reporting Persons and their equityholders, Holdings Manager and certain of its affiliates (“Blackstone”) including the Acquirors, Jasmine Ventures Pte. Ltd. and certain of its affiliates (“GIC” and, together with Blackstone, the “Separately Reporting Persons”), the Reporting Persons and the Separately Reporting Persons may each be deemed to be a member of a “group” for purposes of Section 13(d) of the Exchange Act. However, neither the filing of this Schedule 13D nor any of its contents shall be deemed to constitute an admission that the Reporting Persons or any of the Separately Reporting Persons are members of any such group. Each of the Separately Reporting Persons has separately made a Schedule 13D filing reporting the Class A Shares they may be deemed to beneficially own. Collectively, the Reporting Persons, GIC and Enagas beneficially own an aggregate of 124,307,584 Class A Shares, representing approximately 44.42% of the outstanding Class A Shares. Each Reporting Person disclaims beneficial ownership of the Class A Shares that may be deemed to be beneficially owned by the Separately Reporting Persons.

Item 5(c) of the Statement is amended and supplemented by inserting the following information:

Except as set forth on Schedule 2 attached hereto, none of the Reporting Persons has effected any transactions in Class A Shares since the filing of Amendment No. 1.

Item 6.

Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer.

Item 6 of the Schedule 13D is hereby amended as follows:

The information under the heading “10b5-1 Purchase Plan and Secondary Acquirors” is hereby amended by inserting the following sentence at the end of the second paragraph:

On May 9, 2019, the Prairie Secondary Acquirors terminated the 10b5-1 Purchase Plan.

Except as otherwise noted, the price reported in this column is a weighted average price. These shares were purchased in multiple transactions ranging from $23.62 to $24.50, inclusive. The Reporting Persons undertake to provide to the Issuer, any security holder of the Issuer, or the staff of the Securities and Exchange Commission, upon request, full information regarding the number of shares purchased at each separate price within that range.

The Class A Shares acquired by the Prairie Secondary Acquirors on March 27, 2019 were issuable by the Issuer to certain members of the Issuer’s management in connection with the accelerated vesting of incentive awards held by such persons upon the closing of the transactions contemplated by the Purchase Agreement, dated January 30, 2019, by and among Tallgrass Energy Holdings, LLC, Tallgrass Holdings, LLC, certain affiliates of the Reporting Persons, and other parties thereto. The Prairie Secondary Acquirors agreed to acquire these Class A Shares to provide the selling management members with liquidity consistent with what would have been provided if the incentive awards had been settled in cash.
