Business Description

Note 1. Descr iption of Business Description of Business. We are a fee-based, growth-oriented, Delaware limited partnership formed by Hess Infrastructure Partners GP LLC, the general partner of Hess Infrastructure Partners LP (“HIP”), and our general partner to own, operate, develop and acquire a diverse set of midstream assets and provide fee-based services to Chevron, its subsidiaries, and third-party customers. HIP was originally formed in 2015 as a 50 / 50 joint venture between Hess and GIP . On April 10, 2017, we completed an initial public offering (“IPO”) as a master limited partnership, pursuant to which HIP contributed to the Partnership a 20 % controlling economic interest in each of (i) Hess North Dakota Pipelines Operations LP; (ii) Hess TGP Operations LP; and (iii) Hess North Dakota Export Logistics Operations LP (collectively, the “Joint Interest Assets”) and a 100 % interest in Hess Mentor Storage Holdings LLC. HIP owned the remaining 80 % economic interest in the Joint Interest Assets, a 100 % interest in certain other businesses, including Hess’ Bakken water services business (“Hess Water Services”), which it acquired from Hess on March 1, 2019, and a 100 % interest in Hess Midstream Partners GP LP, which held all of the Partnership’s outstanding incentive distribution rights and the general partner interest in the Partnership, and controlled the Partnership. On December 16, 2019, the Company and the Partnership completed the transactions (the “Restructuring”) contemplated by the Partnership Restructuring Agreement, dated October 3, 2019, by and among the Company, the Partnership and the other parties thereto. Pursuant to the Restructuring, the Partnership acquired HIP, including HIP’s 80 % interest in the Joint Interest Assets, 100 % interest in Hess Water Services and the outstanding economic general partner interest and incentive distribution rights in the Partnership. The Partnership’s organizational structure converted from a master limited partnership into an “Up-C” structure in which the Partnership’s public unitholders received newly issued Class A Shares in the Company in a one-for-one exchange. Class A Shares commenced trading on the New York Stock Exchange under the former symbol “HESM” on December 17, 2019. As a result of the Restructuring, the Company was delegated control of the Partnership and replaced the Partnership as its publicly traded successor. The Partnership changed its name to “Hess Midstream Operations LP” and became a consolidated subsidiary of the Company. On May 30, 2025, GIP sold all of its limited partner interests in the Partnership and no longer holds a direct or indirect ownership interest in the Company, the Partnership or our general partner. See Note 3, Equity Transactions for more details. On July 18, 2025, Hess and Chevron completed the previously announced merger contemplated by the Agreement and Plan of Merger, dated October 22, 2023 (the “Merger”). As a result of the Merger, Chevron is the direct parent of Hess and, therefore, indirectly owns each of the following: • 100 % of the limited liability company interests in Hess Infrastructure Partners GP LLC, the sole member of the general partner of our general partner; • 100 % of the limited liability company interests in Hess Midstream GP LLC, the general partner of our general partner; • 100 % of the partnership interests in Hess Midstream GP LP, our general partner and, through its ownership of the general partner, has the right to elect the entire board of directors; • 100 % of the limited liability company interests in Hess Investments North Dakota LLC (“HINDL”), the holder of 449,000 Class A Shares representing limited partner interests in the Company (“Class A Shares”) and all of the issued and outstanding Class B shares representing limited partner interests in the Company (“Class B Shares”) and Class B units representing limited partner interests in the Partnership (“Class B Units”), which Class B Shares and Class B Units together are exchangeable into Class A Shares and, together with HINDL’s Class A Shares, collectively represent an approximate 37.9 % interest in the Company on a consolidated basis. Throughout this filing and depending on the context, we make references to Chevron, as Chevron, following the completion of the Merger, is our Sponsor and indirectly wholly owns our general partner.…
