Houston, Texas (August 6, 2021) – Summit Midstream Partners, LP (NYSE: SMLP) (“Summit”, “SMLP” or the “Partnership”) announced today its financial and operating results for the three months ended June 30, 2021, including a net loss of $19.7 million, adjusted EBITDA of $62.1 million and DCF of $46.5 million. Net loss for the quarter included $31.5 million of non-cash charges including (i) a $19.3 million loss contingency accrual related to a previously disclosed incident dating back to a 2015 release of produced water from a pipeline owned by Meadowlark Midstream and (ii) an $12.2 million accrual related to Energy Capital Partners' full exercise of equity warrants in exchange for 414,477 SMLP common units. Operated natural gas volume throughput averaged 1,441 million cubic feet per day (“MMcf/d”) and liquids volume throughput averaged 63 thousand barrels per day (“Mbbl/d”). Operated natural gas volumes increased 7.1% relative to the first quarter of 2021, largely due to continued strong performance from the four Utica Shale wells connected in the first quarter of 2021 and 20 new wells that were turned-in-line during the second quarter of 2021 across the Utica Shale, Williston Basin and Marcellus Shale segments. Quarterly liquids volume throughput decreased by 3.1% relative to the first quarter of 2021, primarily as a result of natural production declines.

Heath Deneke, President, Chief Executive Officer and Chairman, commented, “Summit's second quarter financial and operational results far exceeded our original expectations set in March, and adjusted EBITDA of $62.1 million was in line with our recently increased full year 2021 adjusted EBITDA guidance range of $225 million to $240 million. Our quarterly results were driven largely by our continued focus on operational excellence and proactive cost management efforts, together with robust performance from well connections to date. We are encouraged by the substantially improved commodity price backdrop and we continue to see signs of increasing customer activity around our footprint as we look ahead to 2022, particularly in our Permian, Williston and Utica segments. We remain optimistic that this positive momentum will continue to build through the end of the year and into 2022."

"We are making excellent progress towards achieving our holistic refinancing plans of our 2022 debt maturities, which is expected to include a new $400 to $500 million asset-based revolver and a new high yield notes offering of $700 to $750 million. To date, we have received $400 million of ABL Revolver commitments from existing lenders and new lenders, conditioned on the successful arrangement of a new high yield notes offering that we expect to launch during the third quarter of 2021. When completed, the ABL Revolver and new high yield notes will provide a comprehensive financing solution for Summit with enhanced financial flexibility, sufficient liquidity to grow the business and a multi-year runway to continue harvesting substantial free cash flow to further de-lever the balance sheet and drive significant unitholder value going forward. Completing this refinancing plan is the top priority for our team and we are excited about closing this comprehensive financing solution and removing an overhang that has negatively impacted our stakeholders for quite some time."

"We also continue to make excellent progress with construction of the Double E Pipeline while maintaining a premier project safety and compliance record. With construction now approximately 60% complete, we are ahead of schedule and we are well on track to place the project in-service during the fourth quarter of 2021. Additionally,

"Additionally, we recently announced that we have entered into agreements with the government to resolve investigations into the previously disclosed discovery in January 2015 of a produced water spill into Blacktail Creek, near Marmon, North Dakota (the "Blacktail Release"). The spill occurred on a produced water gathering system owned by Meadowlark Midstream, which has been a subsidiary of SMLP since 2016. We have been working to resolve this matter since 2015 and I'm pleased that we have reached a satisfactory settlement resolution for all parties. As part of the settlement, SMLP has agreed to pay an aggregate amount of $36.3 million, which has been fully accrued, and which will be paid over a period of six years to the state of North Dakota and the federal government. A portion of the settlement proceeds will provide funding for supplemental environmental projects in the region. The settlement remains subject to court approval to become effective."

"Safety and the environment are of the utmost importance to Summit, our board and all of our employees. Since the Marmon spill, SMLP has invested approximately $75 million in related environmental remediation efforts as well as made improvements to our operating systems and our company-wide processes and procedures that we believe are leading edge among industry pipeline management best practices."

Over the last several months, Summit has initiated a comprehensive plan to refinance its existing $1.1 billion revolving credit facility, due May 2022 (the "Revolver") and 5.50% senior unsecured notes due 2022 (the “2022 Notes” and together with the Revolver, the “2022 Maturities”). As of today, the 2022 Maturities have an aggregate outstanding principal balance of approximately $969 million, comprised of approximately $735 million outstanding under the Revolver, net of cash, and approximately $234 million outstanding under the 2022 Notes.

To date, Summit has secured $400 million of commitments from a syndicate of existing and new lenders for a new, 4.5-year, asset-based revolving credit facility, based on the value of Summit’s above-ground fixed assets. The closing of the ABL Revolver is conditioned on the successful arrangement of a new $700 million to $750 million high yield notes offering (the "New HY Notes"), which Summit expects to launch and close before the end of September 2021, and other customary closing conditions. The ABL Revolver and the New HY Notes will be scheduled to close concurrently in the third quarter of 2021, and collectively, the proceeds will be used to refinance the 2022 Maturities.

In the second quarter of 2021, SMLP’s average daily natural gas throughput for its operated systems increased by 7.1% to 1,441 MMcf/d, and liquids volumes decreased by 3.1% to 63 Mbbl/d, relative to the first quarter of 2021. SMLP’s customers are currently operating five drilling rigs on acreage behind SMLP's gathering systems and had approximately 22 DUCs in inventory upstream of its systems as of June 30, 2021, with visible line of sight to completions for the majority of these DUCs by the end of the third quarter of 2021.

•Utica Shale segment adjusted EBITDA totaled $10.7 million, a 38.0% increase over the first quarter of 2021, which was driven primarily by an 86 MMcf/d increase in quarterly volume throughput. The 4-well pad that was connected in March of 2021, produced in excess of 170 MMcf/d in the second quarter and six new wells were turned-in-line behind the TPL-7 interconnect during the quarter. At June 30, 2021, our Utica Shale customers had four DUCs, which are all expected to be turned-in-line by the end of the year. Both the 4-well pad that was connected in the first quarter and these four DUCs are subject to a gathering agreement we amended last year, structured to incentivize accelerated upstream activity and increased throughput volumes behind our SMU system.

•Ohio Gathering segment adjusted EBITDA totaled $6.8 million, which is in-line with first quarter of 2021, driven by lower operating expenses, which were partially offset by lower revenues due to a 7.9% decrease in volume throughput. Three wells were connected during the second quarter of 2021, and there are four DUCs that are expected to be turned-in-line in the third quarter of 2021.

behind the Bison gas gathering system in the second quarter of 2021 and quarterly natural gas volume throughput of 12 MMcf/d was in-line with the first quarter 2021 results. There were six DUCs in inventory behind our liquids focused system as of June 30, 2021, all of which are expected to be turned-in-line by the end of the third quarter.

•DJ Basin segment adjusted EBITDA totaled $5.1 million in the second quarter of 2021, a 4.5% decrease from the first quarter of 2021, primarily due to changes in customer volume mix. Second quarter volume throughput averaged 23 MMcf/d, which was in-line with first quarter volume throughput and as of June 30, 2021, there were no DUCs behind our DJ Basin infrastructure expected to be turned-in-line in the near-term.

•Permian Basin segment adjusted EBITDA totaled $0.5 million in the second quarter of 2021, a decrease of approximately $0.2 million compared to the first quarter of 2021, largely due to increased operating expenses for compressor related maintenance and property taxes, despite flat quarterly throughput volumes of 29 MMcf/d. There were no new wells connected during the quarter and no DUCs currently behind the Permian system; however, there has been an increase in commercial discussions that could result in incremental volumes in the fourth quarter of 2021.

•Piceance Basin segment adjusted EBITDA of $20.3 million decreased by 3.4% from the first quarter of 2021, primarily due to 14 MMcf/d of lower volume throughput, compared to the first quarter of 2021. There were no new wells connected in the second quarter behind our Piceance infrastructure and volume throughput decreased primarily as a result of natural production declines.

•Barnett Shale segment adjusted EBITDA of $8.9 million increased by 10.9% from the first quarter of 2021, primarily due to a combination of lower operating expenses, changes in customer margin mix and an increase in quarterly volumes. Although there were no new wells turned-in-line during the quarter, throughput volumes increased by 1.5% over the first quarter of 2021 due to workovers and recompletions of existing wells. Our customers have seven DUCs that are scheduled to be turned-in-line in the third quarter of 2021.

As of June 30, 2021, SMLP had $762 million drawn under its $1.1 billion Revolver and $314.9 million of undrawn commitments, after accounting for $23.1 million of issued, but undrawn letters of credit. Year-to-date through June 30, 2021, SMLP has reduced the drawn balance on the Revolver by $95 million, including $40 million in the second quarter of 2021. Subject to covenant limits, our available borrowing capacity at June 30, 2021 totaled approximately $138 million. SMLP also had $7.2 million of unrestricted cash on hand as of June 30, 2021.

Based upon the terms of SMLP’s Revolver, and total outstanding debt, net of cash, of $1.25 billion (inclusive of $493.5 million of senior unsecured notes), SMLP’s total leverage ratio and first lien leverage ratio (as defined in the credit agreement) as of June 30, 2021, were 5.0 to 1.0 and 3.0 to 1.0, respectively, relative to maximum threshold limits of 5.75 to 1.0 and 3.50 to 1.0.

As of today, construction of the Double E Pipeline is approximately 60% complete and all of the identified complex construction activities have been completed. The project is progressing ahead of schedule and costs continue to track well below budget. Summit continues to expect that it will commission Double E and commence service in the fourth quarter of 2021. Summit funded all of its $42.8 million of Double E capital calls in the second quarter of 2021 with borrowings under the non-recourse credit facilities at its wholly-owned, unrestricted subsidiary, Summit Permian Transmission, LLC (“Permian Transmission”). As of June 30, 2021, there was $53.5 million outstanding under the Permian Transmission credit facility.

SMLP billed its customers $11.5 million in the second quarter of 2021 related to MVC shortfalls. For those customers that do not have MVC shortfall credit banking mechanisms in their gathering agreements, the MVC shortfall payments are accounted for as gathering revenue in the period in which they are earned. In the second quarter of 2021, SMLP recognized $13.6 million of gathering revenue associated with MVC shortfall payments.

We report financial results in accordance with U.S. generally accepted accounting principles (“GAAP”). We also present adjusted EBITDA, a non-GAAP financial measure. We define adjusted EBITDA as net income or loss, plus interest expense, income tax expense, depreciation and amortization, our proportional adjusted EBITDA for equity method investees, adjustments related to MVC shortfall payments, adjustments related to capital reimbursement activity, unit-based and noncash compensation, impairments, items of income or loss that we characterize as unrepresentative of our ongoing operations and other noncash expenses or losses, less interest income, income tax benefit, income (loss) from equity method investees and other noncash income or gains. Because adjusted EBITDA may be defined differently by other entities in our industry, our definition of this non-GAAP financial measure may not be comparable to similarly titled measures of other entities, thereby diminishing its utility.

Management uses adjusted EBITDA in making financial, operating and planning decisions and in evaluating our financial performance. Furthermore, management believes that adjusted EBITDA may provide external users of our financial statements, such as investors, commercial banks, research analysts and others, with additional meaningful comparisons between current results and results of prior periods as they are expected to be reflective of our core ongoing business.

•the financial performance of our assets without regard to (i) income or loss from equity method investees, (ii) the impact of the timing of minimum volume commitments shortfall payments under our gathering agreements or (iii) the timing of impairments or other income or expense items that we characterize as unrepresentative of our ongoing operations.

We do not provide the GAAP financial measures of net income or loss or net cash provided by operating activities on a forward-looking basis because we are unable to predict, without unreasonable effort, certain components thereof including, but not limited to, (i) income or loss from equity method investees and (ii) asset impairments. These items are inherently uncertain and depend on various factors, many of which are beyond our control. As such, any associated estimate and its impact on our GAAP performance and cash flow measures could vary materially based on a variety of acceptable management assumptions.
