Explanatory Note

This Amendment No. 2 (“Amendment No. 2”) to Schedule 13D relates to the shares of Class A Common Stock, par value $0.01 per share (the “Common Stock”), of SemGroup Corporation, a Delaware corporation (the “Issuer”), and amends the initial statement on Schedule 13D filed on October 26, 2017 (the “Original Schedule 13D”), as amended by Amendment No. 1 to the Schedule 13D filed on November 6, 2017 (the Original Schedule 13D, as amended, the “Schedule 13D”). Capitalized terms used but not defined in this Amendment No. 2 shall have the same meanings ascribed to them in the Schedule 13D.

Harvest Fund Advisors LLC (“HFA”), an investment management firm with over $10 billion in assets under management, initially filed a Schedule 13G with respect to the Common Stock of the Issuer pursuant to Rule 13d-1(b) under the Securities Exchange Act of 1934, as amended, on February 5, 2016. On October 16, 2017, a subsidiary of The Blackstone Group L.P. acquired HFA. In connection with that acquisition, The Blackstone Group L.P. and certain of its affiliates (the “Blackstone Reporting Persons”) may have been deemed to have become the beneficial owner of the securities beneficially owned by HFA at such time, including the securities of the Issuer, and HFA and the Blackstone Reporting Persons together reported beneficial ownership of such securities on a Schedule 13D.

As of March 30, 2018, the business comprising HFA (the “HFA Business”) will calculate and report beneficial ownership over securities separately from the rest of The Blackstone Group L.P. and its affiliates other than those comprising the HFA Business (“Blackstone”), in accordance with Securities and Exchange Commission Release No. 34-39538 (the “Release”). As a result of the foregoing, and as reflected in this Amendment, the Blackstone Reporting Persons ceased to be beneficial owners of more than 5% of the securities of the Issuer on March 30, 2018. The securities of the Issuer beneficially owned by the HFA Business are being separately reported on a Schedule 13G, which filing will not reflect securities, if any, beneficially owned by Blackstone, whose ownership has been disaggregated from that of the HFA Business in accordance with the Release.

Item 2. Identity and Background

Item 2 of the Schedule 13D is hereby amended to reflect the removal of HFA as a Reporting Person on this Schedule 13D as described in the Explanatory Note above.

Item 5. Interest in Securities of the Issuer.

Item 5 of the Schedule 13D is hereby amended and restated as follows:

(a) and (b). None of the Reporting Persons beneficially owns any Common Stock as of March 30, 2018.

(c) Except as set forth in Schedule 1 of this Schedule 13D (which reflects transactions prior to the disaggregation of the HFA Business from the rest of Blackstone as of March 30, 2018), as of March 30, 2018, none of the Reporting Persons has effected any transaction in the past 60 days in Common Stock.

(d) Not applicable.

(e) Upon the disaggregation of the HFA Business from the rest of Blackstone as of March 30, 2018, the Reporting Persons ceased to beneficially own more than five percent of the outstanding Common Stock.


SIGNATURES

After reasonable inquiry and to the best of its or his knowledge and belief, each of the undersigned certifies that the information set forth in this statement is true, complete and correct.
