Guidance:

Following strong year-to-date 2021 results, Hess Midstream LP is updating its full year 2021 net income guidance to $590 - $610 million and raising its full year 2021 Adjusted EBITDA guidance to $880 - $900 million.
Following Hess Corporation's announcement of increasing rig count in the Bakken to 3 rigs in September 2021, Hess Midstream LP is increasing its full year 2021 expansion capital guidance to $165 million.
Hess Midstream LP is reiterating its annual distribution per share growth target of at least 5% through 2023 from the new higher per share distribution level with expected annual distribution coverage greater than 1.4x.
Hess Midstream LP is reaffirming its previously announced expectation of continued growth in Adjusted EBITDA in 2022 and 2023 and continued Adjusted Free Cash Flow generation sufficient to fully fund growing distributions, creating additional capital allocation flexibility.

Hess Midstream LP (NYSE:HESM) ("Hess Midstream") today reported second quarter 2021 net income of $162.0 million compared with net income of $107.8 million for the second quarter of 2020. After deduction for noncontrolling interests, net income attributable to Hess Midstream was $11.0 million, or $0.44 per Class A share. Hess Midstream generated Adjusted EBITDA of $230.2 million. Distributable Cash Flow ("DCF") for the second quarter of 2021 was $207.5 million and Adjusted Free Cash Flow was $162.6 million.

"Hess Midstream delivered another strong quarter, marked by higher gas capture and lower than expected costs," said John Gatling, President and Chief Operating Officer of Hess Midstream. "Looking ahead, we are poised for organic growth and continued adjusted free cash flow as Hess Corporation adds a third rig in September. Furthermore, our decision to return capital to shareholders underscores our confidence in Hess Midstream's financial stability and trajectory for future volume growth."

Hess Midstream's results contained in this release are consolidated to include the noncontrolling interests in Hess Midstream Operations LP owned by affiliates of Hess Corporation ("Hess") and Global Infrastructure Partners ("GIP"). We refer to certain results as "attributable to Hess Midstream LP," which exclude the noncontrolling interests in Hess Midstream Operations LP owned by Hess and GIP.

Financial Results

Revenues and other income in the second quarter of 2021 were $294.8 million compared with $269.8 million in the prior-year quarter. Second quarter 2021 revenues included $18.6 million of pass-through rail transportation, electricity, produced water trucking and disposal costs and $18.7 million of shortfall fee payments related to minimum volume commitments compared with $46.0 million and $3.1 million, respectively, in the prior-year quarter. Second quarter 2021 revenues and other income were up $25.0 million compared to the prior-year quarter primarily due to higher minimum volume commitment levels and tariff rates, partially offset by lower pass-through transportation revenues. Total costs and expenses in the second quarter of 2021 were $109.2 million, down from $138.0 million in the prior-year quarter. The decrease was primarily attributable to lower pass-through transportation costs.

Net income for the second quarter of 2021 was $162.0 million, or $0.44 per Class A share, after deduction for noncontrolling interests. Substantially all of income tax expense was attributed to earnings of Class A shares reflective of our organizational structure. Net cash provided by operating activities for the second quarter of 2021 was $224.6 million.

Adjusted EBITDA for the second quarter of 2021 was $230.2 million. Relative to distributions, DCF for the second quarter of 2021 of $207.5 million resulted in an approximately 1.4x distribution coverage ratio. Adjusted Free Cash Flow for the second quarter of 2021 was $162.6 million.

Operational Highlights

Throughput volumes increased 6% for gas gathering and 5% for gas processing in the second quarter of 2021 compared with the second quarter of 2020 driven by higher gas capture of Hess volumes. Throughput volumes decreased 21% for crude oil gathering and 19% for crude oil terminaling in the second quarter of 2021 compared with the second quarter of 2020 due to reduced drilling activity. The impact of the reduction in crude oil physical volumes in the second quarter of 2021 compared to the second quarter of 2020 was offset by higher tariff rates and shortfall fee payments related to minimum volume commitments. Water gathering volumes increased 12% compared with the year-ago quarter reflecting continued steady organic growth of our water handling business. Third parties comprised approximately 15% of crude oil gathering and 10% of gas gathering volumes for the second quarter of 2021.

Capital Expenditures

Capital expenditures for the second quarter of 2021 totaled $46.4 million, including $44.9 million of expansion capital expenditures and $1.5 million of maintenance capital expenditures, and were primarily attributable to continued expansion of our compression capacity. Capital expenditures in the prior-year quarter were $78.8 million, including $77.8 million of expansion capital expenditures and $1.0 million of maintenance capital expenditures, and were primarily attributable to construction and fabrication activities for the Tioga Gas Plant expansion.

Quarterly Cash Distributions

Our general partner's board of directors declared a quarterly cash distribution of $0.5042 per Class A share for the second quarter of 2021. The distribution represents an approximate 11% increase compared to the distribution for the first quarter of 2021, consisting of a 10% announced increase in addition to a quarterly increase consistent with Hess Midstream's targeted 5% growth in annual distribution per Class A share. The distribution is expected to be paid on August 13, 2021 to shareholders of record as of the close of business on August 9, 2021.

Unit Repurchase

As separately announced today, Hess Midstream Operations LP, Hess Midstream's consolidated subsidiary, agreed to repurchase approximately 31 million Class B units of Hess Midstream Operations LP from Hess and GIP for an aggregate purchase price of $750 million, resulting in public ownership of Hess Midstream, on a consolidated basis, increasing to approximately 9.5%. The unit repurchase is expected to close in August 2021 and is expected to be funded through debt financing, maintaining targeted leverage of 3x debt / Adjusted EBITDA on a full-year 2021 basis.

Updated 2021 Guidance

Hess Midstream continues to target annual distribution per share growth of at least 5% through 2023 from the new higher distribution per share level with expected annual distribution coverage greater than 1.4x. In 2021 and 2022, Hess Midstream expects revenues that are 95% protected by minimum volume commitments. Hess Midstream is updating its full year 2021 guidance based primarily on strong year-to-date results as follows:

About Hess Midstream

Hess Midstream LP is a fee‑based, growth-oriented midstream company that operates, develops and acquires a diverse set of midstream assets to provide services to Hess 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.

Reconciliation of U.S. GAAP to 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. "Adjusted EBITDA" presented in this release is defined as reported net income (loss) before net interest expense, income tax expense, depreciation and amortization and our proportional share of depreciation of our equity affiliates, 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, non‑recurring items, if applicable. "Distributable Cash Flow" or "DCF" is defined as Adjusted EBITDA less net interest, excluding amortization of deferred financing costs, cash paid for federal and state income taxes and maintenance capital expenditures. DCF does not reflect changes in working capital balances. We define "Adjusted Free Cash Flow" as DCF less expansion capital expenditures and ongoing contributions to equity investments. 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, DCF and Adjusted Free Cash Flow to reported net income (GAAP) and net cash provided by operating activities (GAAP), 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.
