("AAI") may be deemed to beneficially own 30,303,091 Class A shares ("Class A Shares") representing limited partner interests of Hess Midstream LP (the "Issuer"). Of such Class A Shares, 29,908,345 are held by the Alerian MLP ETF, an investment company registered under the Investment Company Act of 1940, for which AAI serves as investment adviser. The remaining 394,746 Class A Shares are held by other funds or accounts for which AAI serves as investment adviser or in a similar capacity. The percentage of Class A Shares beneficially owned by each Reporting Person is calculated based on 129,392,378 Class A Shares outstanding as of October 31, 2025, as reported by the Issuer in its Quarterly Report on Form 10-Q filed with the Securities and Exchange Commission on November 6, 2025. The Issuer operates through an Up-C organizational structure under which affiliates of Chevron Corporation hold Class B units of Hess Midstream Operations LP, the Issuer's consolidated operating subsidiary. Class B units are exchangeable into Class A Shares on a one-for-one basis. The Reporting Persons do not hold any Class B units. The total number of Class A Shares and Class B units on a consolidated, as-exchanged basis is approximately 207 million. The percentage of beneficial ownership reported herein is calculated using the outstanding Class A Shares as the denominator, as those are the sole class registered under Section 12 of the Exchange Act. Prior amendments to this Schedule 13G used the total consolidated share and unit count (inclusive of Class B units) as the denominator for calculating the percentage of class, which resulted in a lower reported percentage. This amendment updates that calculation.
