Net income was $175.5 million. Net cash provided by operating activities was $258.9 million.
Net income attributable to Hess Midstream LP was $97.7 million, or $0.75 basic earnings per Class A share, after deduction for noncontrolling interests.
Adjusted EBITDA¹ was $320.7 million and Adjusted Free Cash Flow¹was $186.8 million.
Completed accretive $70.0 million repurchase of Class A shares of Hess Midstream LP and $30.0 million repurchase of Class B units of Hess Midstream Operations LP.
Increased quarterly cash distribution to $0.7548 per Class A share for the third quarter of 2025, an increase of $0.0178 per Class A share for the third quarter of 2025 compared with the second quarter of 2025. This increase is supported by excess Adjusted Free Cash Flow after distributions from the reduction in total Hess Midstream LP shares and Hess Midstream Operations LP units following the accretive repurchases in the third quarter of 2025.
Throughput volumes increased 10% for gas processing, 7% for oil terminaling and 7% for water gathering compared with the prior‑year quarter, primarily due to higher production.

Guidance:

Hess Midstream LP expects $170 - $180 million of net income and $315 - $325 million of Adjusted EBITDA in the fourth quarter of 2025.
Hess Midstream LP is reducing its full year 2025 capital expenditure guidance to approximately $270 million, implying $70 million of capital expenditures expected in the fourth quarter of 2025, based on suspension of the Capa gas plant and removal of the project from its forward plan.
Hess Midstream LP reiterates updated guidance from the September 18, 2025 news release.

Hess Midstream LP (NYSE:HESM) ("Hess Midstream" or the "Company") today reported third quarter 2025 net income of $175.5 million compared with net income of $164.7 million for the third quarter of 2024. After deduction for noncontrolling interests, net income attributable to Hess Midstream was $97.7 million, or $0.75 basic earnings per Class A share, compared with $0.63 basic earnings per Class A share in the third quarter of 2024. Hess Midstream generated Adjusted EBITDA of $320.7 million. Net cash provided by operating activities was $258.9 million and Adjusted Free Cash Flow was $186.8 million.

"We delivered solid operational performance in the third quarter, growing gas throughput across our systems on a year-over-year and sequential basis," said Jonathan Stein, Chief Executive Officer of Hess Midstream. "We remain focused on continuing to deliver safe and reliable execution, reducing costs and returning capital to our shareholders."

On July 18, 2025, Hess Corporation ("Hess") and Chevron completed the previously announced merger contemplated by the Agreement and Plan of Merger, dated as of October 22, 2023 (the "Merger"). As a result of the Merger, Chevron is the direct parent of Hess and, therefore, indirectly owns an approximately 37.9% interest in Hess Midstream on a consolidated basis.

Hess Midstream's results contained in this release are consolidated to include the noncontrolling interests in Hess Midstream Operations LP (the "Partnership") owned by affiliates of Chevron and, up until May 30, 2025, by Global Infrastructure Partners, a part of BlackRock ("GIP" and together with Chevron, the "Sponsors"). 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 or the Partnership. We refer to certain results as "attributable to Hess Midstream LP," which exclude the noncontrolling interests in the Partnership owned by the Sponsors.

¹	Adjusted EBITDA and Adjusted Free Cash Flow are non‑GAAP measures. Definitions and reconciliations of these non‑GAAP measures to the most directly comparable GAAP reporting measures appear in the following pages of this release.

Financial Results

Revenues and other income in the third quarter of 2025 were $420.9 million compared with $378.5 million in the prior‑year quarter. Third quarter 2025 revenues included $27.9 million of pass-through electricity, produced water trucking and disposal costs and certain other fees compared with $24.8 million in the prior-year quarter. Third quarter 2025 revenues and other income were up $42.4 million compared with the prior-year quarter, primarily due to higher physical volumes and higher tariff rates. Total operating costs and expenses in the third quarter of 2025 were $162.0 million, up from $146.8 million in the prior-year quarter, primarily due to higher employee costs, depreciation and pass-through electricity and produced water trucking and disposal costs. Interest expense, net of interest income, in the third quarter of 2025 was $57.1 million, up from $51.8 million in the prior-year quarter, primarily due to higher borrowings under the Company's revolving credit facility.

Net income for the third quarter of 2025 was $175.5 million, or $0.75 basic earnings per Class A share, after deduction for noncontrolling interests, compared with $0.63 basic earnings per Class A share in the prior-year quarter. Substantially all of income tax expense was attributed to earnings of Class A shares reflective of Hess Midstream's organizational structure. Net cash provided by operating activities for the third quarter of 2025 was $258.9 million.

Adjusted EBITDA for the third quarter of 2025 was $320.7 million. Adjusted Free Cash Flow for the third quarter of 2025 was $186.8 million.

At September 30, 2025, Hess Midstream had a drawn balance of $356.0 million on its revolving credit facility. On July 24, 2025, Hess Midstream's senior unsecured debt was upgraded by S&P to an investment grade rating of BBB-.

Operational Highlights

In the third quarter of 2025, Hess Midstream completed construction of a new compressor station. The new station provides approximately 35 MMcf/d of installed capacity and can be expanded to provide an additional 35 MMcf/d in the future.

Throughput volumes increased 10% for gas processing, 7% for oil terminaling and 7% for water gathering in the third quarter of 2025 compared with the third quarter of 2024, primarily due to higher production and higher third-party gas volumes.

Capital Expenditures

Capital expenditures for the third quarter of 2025 totaled $79.8 million compared with $96.3 million in the prior‑year quarter and related primarily to continued expansion of Hess Midstream's gas compression and associated pipeline infrastructure.

Quarterly Cash Distributions

On October 27, 2025, the Board of Directors of Hess Midstream's General Partner declared a quarterly cash distribution of $0.7548 per Class A share for the third quarter of 2025, an increase of $0.0178 per Class A share as compared with the second quarter of 2025. This increase is supported by excess Adjusted Free Cash Flow after distributions from the reduction in total Hess Midstream LP shares and Hess Midstream Operations LP units following the accretive repurchases in the third quarter of 2025. The distribution is expected to be paid on November 14, 2025, to shareholders of record as of the close of business on November 6, 2025.

Guidance

For the fourth quarter of 2025, Hess Midstream expects net income of $170 - $180 million and Adjusted EBITDA of $315 - $325 million based on scheduled maintenance activities and lower third-party volumes as disclosed in the September 18, 2025 news release, implying full year expected net income of $685 - $695 million and Adjusted EBITDA of $1,245 - $1,255 million.

Hess Midstream is reaffirming its full year 2025 throughput guidance. Hess Midstream is also updating its full year 2025 capital expenditure guidance to approximately $270 million based on suspension of the Capa gas plant and removal of the project from its forward plan.

About Hess Midstream

Hess Midstream LP is a fee‑based, growth-oriented midstream company that owns, operates, develops and acquires a diverse set of midstream assets to provide services to Chevron, its subsidiaries, and third‑party customers. Hess Midstream owns oil, gas and produced water handling assets that are primarily located in the Bakken and Three Forks Shale plays in the Williston Basin area of North Dakota. More information is available at www.hessmidstream.com.

As used in this news release, the term "Chevron" may refer to Chevron Corporation, one or more of its consolidated subsidiaries, or to all of them taken as a whole. All of these terms are used for convenience only and are not intended as a precise description of any of the separate companies, each of which manages its own affairs.

Non‑GAAP Measures

In addition to our financial information presented in accordance with U.S. generally accepted accounting principles ("GAAP"), management utilizes certain additional non‑GAAP measures to facilitate comparisons of past performance and future periods. We define "Adjusted EBITDA" as reported net income (loss) before net interest expense, income tax expense (benefit), and depreciation and amortization, as further adjusted to eliminate the impact of certain items that we do not consider indicative of our ongoing operating performance, such as transaction costs, other income and other non‑cash and non‑recurring items, if applicable. We define "Adjusted Free Cash Flow" as Adjusted EBITDA less net interest, excluding amortization of deferred financing costs, cash paid for federal and state income taxes, capital expenditures and ongoing contributions to equity investments. We define "Gross Adjusted EBITDA Margin" as the ratio of Adjusted EBITDA to total revenues, less pass-through revenues. We believe that investors' understanding of our performance is enhanced by disclosing these measures as they may assist in assessing our operating performance as compared to other publicly traded companies in the midstream energy industry, without regard to historical cost basis or, in the case of Adjusted EBITDA, financing methods, and assessing the ability of our assets to generate sufficient cash flow to make distributions to our shareholders. These measures are not, and should not be viewed as, a substitute for GAAP net income or cash flow from operating activities and should not be considered in isolation. Reconciliations of Adjusted EBITDA, Adjusted Free Cash Flow and Gross Adjusted EBITDA Margin to reported net income (GAAP), net cash provided by operating activities (GAAP) and gross margin (GAAP), respectively, are provided below. Hess Midstream is unable to project net cash provided by operating activities with a reasonable degree of accuracy because this metric includes the impact of changes in operating assets and liabilities related to the timing of cash receipts and disbursements that may not relate to the period in which the operating activities occur. Therefore, Hess Midstream is unable to provide projected net cash provided by operating activities, or the related reconciliation of projected Adjusted Free Cash Flow to projected net cash provided by operating activities without unreasonable effort.
