Guidance:

Hess Midstream LP is updating its 2026 capital expenditures guidance to approximately $105 million and increasing its Adjusted Free Cash Flow guidance to $910 - $960 million as a result of lower capital expenditures and deferral of income tax payments.
Hess Midstream LP is reaffirming its full year 2026 throughput, net income and Adjusted EBITDA guidance.

Hess Midstream LP (NYSE:HESM) ("Hess Midstream" or the "Company") today reported first quarter 2026 net income of $157.7 million compared with net income of $161.4 million for the first quarter of 2025. After deduction for noncontrolling interests, net income attributable to Hess Midstream was $87.6 million, or $0.68 basic earnings per Class A share, compared with $0.65 basic earnings per Class A share in the first quarter of 2025. Hess Midstream generated Adjusted EBITDA of $299.8 million. Net cash provided by operating activities was $253.3 million and Adjusted Free Cash Flow was $237.0 million.

"In the first quarter, we continued to execute on our operational priorities and delivered on our financial strategy," said Jonathan Stein, Chief Executive Officer of Hess Midstream. "We are focused on safe, reliable and efficient execution, and have lowered our expected capital spend for the year, supporting additional Adjusted Free Cash Flow for continued shareholder returns and debt repayment."

Hess Midstream's results contained in this release are consolidated to include the noncontrolling interests in Hess Midstream Operations LP (the "Partnership") owned by our Sponsor. References to "Sponsor" or "Sponsors" refer to (a) Hess Corporation ("Hess") and Global Infrastructure Partners when referring to periods prior to May 30, 2025, (b) Hess from May 30, 2025, to July 17, 2025, and (c) Chevron from July 18, 2025. We refer to certain results as "attributable to Hess Midstream LP," which exclude the noncontrolling interests in the Partnership owned by the Sponsors.

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.

⁽¹⁾	Adjusted EBITDA, Adjusted Free Cash Flow and Adjusted Free Cash Flow after Distributions 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 first quarter of 2026 were $390.1 million compared with $382.0 million in the prior‑year quarter. First quarter 2026 revenues included $30.6 million of pass-through electricity, produced water trucking and disposal costs and certain other fees compared with $25.5 million in the prior-year quarter. First quarter 2026 revenues and other income were up $8.1 million compared with the prior-year quarter, primarily due to higher tariff rates, third-party services and pass-through revenues, partially offset by lower throughput volumes. Total operating costs and expenses in the first quarter of 2026 were $152.0 million, up from $144.6 million in the prior-year quarter, primarily due to higher depreciation expense. Interest expense, net of interest income, in the first quarter of 2026 was $55.4 million, approximately flat compared with $56.4 million in the prior-year quarter.

Net income for the first quarter of 2026 was $157.7 million, or $0.68 basic earnings per Class A share, after deduction for noncontrolling interests, compared with $0.65 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 first quarter of 2026 was $253.3 million.

Adjusted EBITDA for the first quarter of 2026 was $299.8 million. Adjusted Free Cash Flow for the first quarter of 2026 was $237.0 million.

At March 31, 2026, Hess Midstream had a drawn balance of $343.0 million on its revolving credit facility.

Operational Highlights

Throughput volumes decreased 5% for oil terminaling and 9% for water gathering compared with the first quarter of 2025, primarily due to lower production as a result of lower new-well activity. Throughput volumes increased 1% for gas processing in the first quarter of 2026 compared with the first quarter of 2025, primarily due to higher third-party volumes.

Capital Expenditures

Capital expenditures for the first quarter of 2026 totaled $10.4 million compared with $50.1 million in the prior‑year quarter, a 79% decrease resulting mainly from the completion of Hess Midstream's expansion of its gas compression capacity.

Quarterly Cash Distributions

On April 27, 2026, the Board of Directors of Hess Midstream's General Partner declared a quarterly cash distribution of $0.7792 per Class A share for the first quarter of 2026, an increase of $0.0151 per Class A share as compared with the fourth quarter of 2025. This increase is supported by the reduction in total Hess Midstream LP shares and Hess Midstream Operations LP units following the accretive repurchases in the first quarter of 2026. The distribution is expected to be paid on May 14, 2026, to shareholders of record as of the close of business on May 7, 2026.

Updated Guidance

Hess Midstream now expects total capital expenditures of approximately $105 million in 2026. Hess Midstream no longer expects to pay income tax in 2026 and does not expect to pay material income taxes until after 2028 as a result of the recently issued Additional Interim Guidance Regarding the Application of the Corporate Alternative Minimum Tax. As a result, Hess Midstream is increasing its full year 2026 Adjusted Free Cash Flow guidance to $910 - $960 million and expects approximately $280 million Adjusted Free Cash Flow after Distributions¹ at the midpoint of the updated guidance range after funding distributions that are targeted to grow at least 5% per annum on a distribution per Class A share basis. Hess Midstream continues to expect to generate approximately $1 billion of Adjusted Free Cash Flow after Distributions through 2028 that is expected to be available for incremental shareholder returns and debt repayment.

Hess Midstream is reaffirming its full year 2026 throughput, net income and Adjusted EBITDA guidance.

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 "Adjusted Free Cash Flow after Distributions" as Adjusted Free Cash Flow less cash distributions to shareholders and to noncontrolling interest. 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.
