Company

The board of directors for Hess Midstream GP LLC comprises a maximum of eight directors, of which no more than four directors may be affiliated with Chevron and the remaining directors must be independent as defined under the independence standards established by the NYSE and the Exchange Act. The board currently comprises four members appointed by Chevron and three who are independent.

The board has an audit committee and, from time to time, a conflicts committee.

Audit Committee

Our audit committee assists the board of directors in its oversight of the integrity of financial statements and compliance with legal and regulatory requirements and corporate policies and controls. It has sole authority to retain and terminate our independent registered public accounting firm, approve all auditing services and related fees and the terms thereof, and pre-approve any non-audit services to be rendered by our independent registered public accounting firm. It also is responsible for confirming the independence and objectivity of our independent registered public accounting firm.

Conflicts Committee

Our conflicts committee reviews specific matters that may involve conflicts of interest in accordance with the terms of our partnership agreement. The board of directors determines whether to refer a matter to the conflicts committee on a case-by-case basis. Members may not be officers or employees of our general partner or directors, officers or employees of its affiliates (including Chevron).

Executive Sessions

Independent directors generally meet in executive session after each regularly scheduled board meeting. Mr. Niemiec, the Chairman of the Audit Committee, presides at these sessions.
