Explanatory Note

Harvest Fund Advisors LLC (“HFA”) initially filed a Schedule 13G on May 8, 2015 with respect to the common units representing limited partner interests (the “Common Units”) of Rice Midstream Partners LP (the “Issuer”), pursuant to Rule 13d-1(b) under the Securities Exchange Act of 1934, as amended. 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, including the securities of the Issuer, and HFA and the Blackstone Reporting Persons together reported beneficial ownership of such securities on a Schedule 13D on October 26, 2017.

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, the securities of the Issuer beneficially owned by the HFA Business are being reported on a Schedule 13G pursuant to Rule 13d-1(b), which filing supersedes and replaces the Schedule 13D previously filed by HFA, and which Schedule 13G filing does not reflect securities, if any, beneficially owned by Blackstone.
