Summit Midstream Partners, LP Reports Second Quarter 2022

Financial and Operating Results

•Second quarter 2022 net loss of $91.8 million, adjusted EBITDA of $50.5 million and cash flow available for distributions ("Distributable Cash Flow" or "DCF") of $25.6 million

•Adjusted EBITDA was impacted by approximately $3.6 million of estimated weather-related interruptions in the Rockies segment, maintenance activities and wells temporarily shut-in behind the Northeast segment and deal costs incurred during the quarter

•Sold the Lane Gathering and Processing System in the Delaware Basin and assigned the associated take-or-pay firm capacity on Double E to a Subsidiary of Matador Resources Company for $75 million in cash

•Reduced total debt by $82 million, increasing available liquidity to approximately $255 million

•Expect to be at the high-end of previously announced 2022 Adjusted EBITDA guidance range of $205 million to $220 million

•Current producer development plans include at least 200 new well connections in 2023 behind our systems, which we expect to result in at least 10% year-over-year Adjusted EBITDA growth

Houston, Texas (August 4, 2022) - 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, 2022, including a net loss of $91.8 million, adjusted EBITDA of $50.5 million and DCF of $25.6 million. SMLP also recognized an impairment of $84.5 million related to the sale of its Lane Gathering and Processing System in the Delaware Basin. Operated natural gas throughput from wholly owned assets averaged 1,200 million cubic feet per day ("MMcf/d") and liquids throughput averaged 54 thousand barrels per day ("Mbbl/d"). Total quarterly natural gas gathering volume throughput, including SMLP's proportionate share from OGC and Double E, decreased 32 MMcf/d relative to the first quarter of 2022, primarily due to approximately 55 MMcf/d of reductions resulting from maintenance activities and wells temporarily shut-in behind the Northeast segment, partially offset by nearly 70% volume growth behind Double E. Natural gas volumes benefited from 8 new wells brought online behind our wholly owned systems and 6 new wells brought online behind our Ohio Gathering joint venture during the quarter. Second quarter 2022 liquids volume decreased by 11 Mbbl/d, or 16.9% relative to the first quarter of 2022 primarily due to severe winter weather in North Dakota and no new wells brought online during the quarter.

Heath Deneke, President, Chief Executive Officer and Chairman, commented, "Summit's second quarter 2022 financial and operating results were ahead of internal expectations, despite approximately $3.6 million of unexpected weather, maintenance and deal costs, which was driven by continued strong performance from recent wells turned in line and lower than anticipated operating expenses for the quarter. I'd like to thank our team up in North Dakota for the significant effort made to get our systems back online safely and quickly. Based on year-to-date financial results and the timing and performance of recent well connections in 2022, we believe we will trend toward the high end of our previously announced Adjusted EBITDA guidance range of $205 to $220 million. We continue to see strong momentum behind our systems throughout the second half of the 2022 and into 2023 which we believe positions SMLP for strong growth in 2023."

"Based on recent customer development plans, permitting and rig activity, and commodity price expectations of over $80 per barrel of crude oil and over $5 per MMBtu of natural gas in 2023, we currently expect to connect at least 200 wells to our systems in 2023. While this remains below pre-pandemic average well connections of approximately 260 wells per year, this would be a 80% increase from the average wells connected to the system in 2021 and 2022. We are seeing positive momentum in virtually all our operating segments. In the Northeast, along with increasing activity, we are optimistic about the potential impact of Ascent Resources, LLC's recently announced acquisition of ~26,800 net acres in the Utica that is dedicated to our wholly owned SMU system. In the Piceance, we continue to work with our customers on a multi-year development program that would bring approximately 200 wells online over the next couple years. We expect the first batch of approximately 15 to 20 wells to come online

1

beginning in Q2 2023 and continue thereafter. We believe this activity will offset natural production declines and result in modest volume growth longer-term in the Piceance. In the Barnett, we are currently working with our customers on a development program that includes over 30 new wells in 2023. The outperformance of recent well results and increased level of activity in 2023 would drive meaningful volume growth behind that segment. In the Williston, we expect to be at the higher end of our previously announced 45 - 65 well connections in 2022 and based on recent customer conversations we believe there could be comparable levels of well connections in 2023. This level of activity would drive meaningful liquids volume growth behind the system over the next several quarters. While it's still too early to formally provide 2023 guidance, we believe this level of well connection activity and continued contracted EBITDA growth behind our Double E joint venture to generate at least 10% year-over-year Adjusted EBITDA growth in 2023. We are excited about the potential impact of this growth on our business and balance sheet and will continue to provide updates throughout the year as our customer's plans further develop."

"We also achieved another key milestone during the quarter with the sale of our Lane Gathering & Processing System to a wholly owned subsidiary of Matador Resources Company ("Matador") for a cash sale price of $75 million and the assumption of an additional 60 MMcf/d take-or-pay firm capacity behind Double E. The transaction reduced our total leverage ratio by ~0.3x and increased our total liquidity to $255 million as of June 30, 2022. The transaction also expands Double E's commercial relationship with Matador, a significant acreage holder owning nearly 125,000 net acres in Eddy and Lea Counties in southeastern New Mexico. Matador now has two gas processing complexes connected to the Double E system, Matador's interest in San Mateo Midstream, LLC's 460 MMcf/d Black River Processing Plant Complex and the 60 MMcf/d Lane G&P System acquired from us. Additionally, as the availability of pipeline takeaway capacity out of New Mexico continues to tighten with current levels of drilling activity, we are in active dialogue with multiple new shippers to fill up the remaining unsubscribed firm capacity in Double E and potentially further expand the pipeline's capacity to over 2.0 Bcf per day."

Second Quarter 2022 Business Highlights

In the second quarter of 2022, SMLP's average daily natural gas throughput for its wholly owned operated systems decreased by 106 MMcf/d to 1,200 MMcf/d, and liquids volumes decreased by 11 Mbb/d to 54 Mbbl/d, relative to the first quarter of 2022. Ohio Gathering Company natural gas throughput decreased 36 MMcf/d to 562 MMcf/d and generated $7.5 million of adjusted EBITDA net to SMLP for the second quarter of 2022. Double E Pipeline gross volumes transported increased 127 MMcf/d to 314 MMcf/d and generated $3.9 million of adjusted EBITDA net to SMLP for the second quarter of 2022. SMLP's customers are currently operating eight drilling rigs on acreage behind SMLP's gathering systems and have approximately 48 wells that have been drilled and are expected to be turned in line later this year.

Natural gas price driven segments:

•Natural gas price driven segments had combined quarterly segment adjusted EBITDA of $41.2 million and combined capital expenditures of $4.6 million in the second quarter of 2022.

•Northeast segment adjusted EBITDA of $18.6 million decreased by $1.5 million from the first quarter of 2022, primarily due to a 14.7% decrease in volume on our wholly owned systems and a 6.1% decrease in volume at our Ohio Gathering Company ("OGC") joint venture. The volume decline was primarily driven by approximately 45 MMcf/d of maintenance related downtime upstream of our TPL-7 connection, approximately 9 MMcf/d of volume temporarily shut-in behind our wholly-owned SMU system and approximately 6 MMcf/d (8/8ths) of volume temporarily shut-in behind our OGC joint venture while customers were completing near-by wells, and natural production declines, partially offset by 6 new condensate wells that came online behind our OGC joint venture. We estimate that the maintenance related downtime and frac-protect activities impacted segment adjusted EBITDA by approximately $0.9 million, net to SMLP, during the quarter. The maintenance and frac-protect activities subsided beginning in July, we connected 4 new wells behind our wholly-owned SMU system in late July 2022 that are producing over 100 MMcf/d, and 9 new wells were recently connected behind our OGC joint venture that are expected to producer over 180 MMcf/d. We believe these activities will serve as a volume catalyst for the Northeast segment beginning in the third quarter of 2022.

•Piceance segment adjusted EBITDA of $15.4 million was generally in line with the first quarter of 2022. Volume throughput was flat with the prior quarter, primarily due to natural production declines, offset by volume from a new 9-well pad that was turned-in-line in October 2021.No new wells were connected during the quarter. We expect 17 permitted wells to be turned-in-line by one of our anchor customers in the fourth quarter of 2022.

2

•Barnett segment adjusted EBITDA of $7.2 million decreased by $2.0 million relative to the first quarter of 2022 primarily due to a $3.0 million increase in operating expenses resulting from commercial settlements that reduced operating expenses in prior periods, partially offset by a 1.5% increase in volume throughput. There were 4 new wells connected to the system at the end of April 2022 that achieved peak volumes of approximately 27 MMcf/d during the quarter. There were also 4 new wells that came online in late July and we expect an additional 4 wells in the fourth quarter of 2022 that are currently being drilled.

Oil price driven segments

•Oil price driven segments generated $18.7 million of combined segment adjusted EBITDA in the second quarter of 2022 and had combined capital expenditures of $1.2 million.

•Permian segment adjusted EBITDA of $4.8 million increased $0.7 million relative to the first quarter of 2022, primarily due to a $0.8 million increase in proportionate EBITDA from our Double E joint venture. The second quarter financial results include the Lane Gathering and Processing System, which we sold on June 30, 2022. Volumes on the Lane Gathering and Processing System were flat relative to the first quarter of 2022. Double E gross volume throughput averaged 314 MMcf/d during the second quarter of 2022, an increase of 127 MMcf/d, or approximately 70% growth relative to the first quarter of 2022. There are currently over 100 rigs running in Eddy and Lea Counties, New Mexico, which we believe will be a catalyst for additional volumes and long-term take-or-pay contracts behind our Double E joint venture.

•Rockies segment adjusted EBITDA of $13.9 million decreased $1.9 million relative to the first quarter of 2022, primarily due to an 11 Mbbl/d, or 16.9% decrease in liquids volumes because of significant weather-related interruptions during the quarter. Liquids volumes were completely shut-in across the system from April 23rd through early-May and ramped back up to normal production in late-May. We estimate that the winter storm reduced liquids volumes by approximately 11 Mbbl/d, accounting for nearly all the sequential volume decline, and impacted gross margin by approximately $1.7 million during the quarter. There were 4 new wells connected behind our gas gathering systems and no new wells connected behind our liquids system during the quarter. There are currently 4 rigs running with over 35 DUCs behind the system and over 25 wells expected to come online in the third quarter of 2022.

Capital & Liquidity

As of June 30, 2022, SMLP had $151 million drawn under its $400 million ABL Revolver and $243.1 million of borrowing availability, after accounting for $5.9 million of issued, but undrawn letters of credit. As of June 30, 2022, SMLP's gross availability based on the borrowing base calculation in the credit agreement was $584 million, which is $184 million greater than the $400 million of lender commitments to the ABL Revolver. As of June 30, 2022 SMLP was in compliance with all financial covenants, including interest coverage of 2.7x relative to a minimum interest coverage covenant of 2.0x and first lien leverage ratio of 0.6x relative to a maximum first lien leverage ratio of 2.5x. As of June 30, 2022, SMLP reported a total leverage ratio of 5.08x.

As of June 30, 2022, the Permian Transmission Credit Facility balance was $157.8 million, a reduction of $2.2 million relative to the December 31, 2021 balance of $160.0 million due to scheduled mandatory amortization. The Permian Transmission Term Loan remains non-recourse to SMLP.

MVC Shortfall Payments

SMLP billed its customers $7.8 million in the second quarter of 2022 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 2022, SMLP recognized $10.1 million of gathering revenue associated with MVC shortfall payments. SMLP had no adjustments to MVC shortfall payments in the second quarter of 2022. SMLP's MVC shortfall payment mechanisms contributed $10.1 million of total adjusted EBITDA in the second quarter of 2022.

Use of Non-GAAP Financial Measures

We report financial results in accordance with U.S. generally accepted accounting principles ("GAAP"). We also present adjusted EBITDA and Distributable Cash Flow, non-GAAP financial measures.

Adjusted EBITDA

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, 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.

Adjusted EBITDA is used as a supplemental financial measure to assess:

6

•the ability of our assets to generate cash sufficient to make future potential cash distributions and support our indebtedness;

•the financial performance of our assets without regard to financing methods, capital structure or historical cost basis;

•our operating performance and return on capital as compared to those of other entities in the midstream energy sector, without regard to financing or capital structure;

•the attractiveness of capital projects and acquisitions and the overall rates of return on alternative investment opportunities; and

•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.

Adjusted EBITDA has limitations as an analytical tool and investors should not consider it in isolation or as a substitute for analysis of our results as reported under GAAP. For example:

•certain items excluded from adjusted EBITDA are significant components in understanding and assessing an entity's financial performance, such as an entity's cost of capital and tax structure;

•adjusted EBITDA does not reflect our cash expenditures or future requirements for capital expenditures or contractual commitments;

•adjusted EBITDA does not reflect changes in, or cash requirements for, our working capital needs; and

•although depreciation and amortization are noncash charges, the assets being depreciated and amortized will often have to be replaced in the future, and adjusted EBITDA does not reflect any cash requirements for such replacements.

We compensate for the limitations of adjusted EBITDA as an analytical tool by reviewing the comparable GAAP financial measures, understanding the differences between the financial measures and incorporating these data points into our decision-making process.

Distributable Cash Flow

We define Distributable Cash Flow as adjusted EBITDA, as defined above, less cash interest paid, cash paid for taxes, net interest expense accrued and paid on the senior notes, and maintenance capital expenditures.

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.
