Summit Midstream Corporation 910 Louisiana Street, Suite 4200 Houston, TX 77002 Summit Midstream Corporation Reports Third Quarter 2024 Financial and Operating Results Houston, Texas (November 12, 2024) – Summit Midstream Corporation (NYSE: SMC) (“Summit”, “SMC” or the “Company”) announced today its financial and operating results for the three months ended September 30, 2024. Highlights • Third quarter 2024 net loss of $197.5 million, including $142.6 million non-cash income tax expense to primarily establish SMC’s deferred tax liability associated with the C-Corp conversion • Generated adjusted EBITDA of $45.2 million, representing approximately 9% quarter-over-quarter growth1, cash flow available for distributions ("Distributable Cash Flow" or “DCF”) of $22.1 million and free cash flow (“FCF”) of $9.9 million • Expect to generate approximately $45 million to $50 million of adjusted EBITDA in the fourth quarter 2024 • Connected 38 wells during the third quarter and maintained an active customer base with six active drilling rigs and more than 100 drilled but uncompleted wells (“DUCs”) behind our systems • Closed the C-Corp conversion and a series of re-financing transactions, further simplifying our corporate structure, extending debt maturities and lowering our cost of capital • Announced the transformative acquisition of Tall Oak Midstream III in the Arkoma Basin and filed the definitive proxy with the special meeting of stockholders expected to occur on November 29, 2024 Management Commentary Heath Deneke, President, Chief Executive Officer and Chairman, commented, “Summit’s third quarter operating and financial results were in line with management expectations, reflecting a very active quarter both corporately and operationally. From a corporate perspective, we closed out the C-Corp conversion, successfully refinanced our balance sheet and announced the transformative acquisition of Tall Oak Midstream III. We believe these transactions continue to position Summit for further growth and significant value-creation for our shareholders. From an operational perspective, we connected 38 wells to the system, have six rigs currently operating behind our footprint and made final investment decision on a $10 million optimization project in the Rockies segment that is anticipated to have an approximate one-year payback period and improve our Adjusted EBITDA margin beginning in the second quarter 2025. Nine of the 38 wells were connected behind our Barnett system which brings total year- to-date well connections in the Barnett to 27 wells, with a rig continuing to drill wells expected in 2025. The other 29 wells connected during the quarter came from the DJ Basin, bringing total year-to-date wells to 86, exceeding our expectations with activity levels and volumes behind the system remaining robust. Additionally, as a brief update to our recently announced Tall Oak acquisition, we continue to expect to close the transaction during the fourth quarter of 2024. Since announcement, the Tall Oak management team executed a new contract for approximately 20 MMcf/d of existing in-basin production that is expected to begin deliveries to Tall Oak in the second half of 2025 and continue to see the active rig drilling wells that are expected to come online as soon as the end of this year. We filed the definitive proxy on October 31, 2024 with the special meeting of stockholders currently scheduled on November 29, 2024. Each shareholder’s vote is important to us so we encourage all shareholders to vote.” Third Quarter 2024 Business Highlights SMC’s average daily natural gas throughput for its wholly owned operated systems decreased 6.8% to 667 MMcf/d, and liquids volumes decreased 6.7% to 70 Mbbl/d, relative to the second quarter of 2024. Double E Pipeline gross volumes transported increased from 549 MMcf/d to 661 MMcf/d, a 20.4% increase quarter-over-quarter and generated $8.5 million of adjusted EBITDA, net to SMC, for the third quarter of 2024. EXHIBIT 99.1 1 1 Normalized for $1.6 million of Northeast segment adjusted EBITDA generated in the second quarter 2024
Natural gas price-driven segments: • Natural gas price-driven segments had combined quarterly segment adjusted EBITDA of $20.1 million, representing a 1.1% increase relative to the second quarter and combined capital expenditures of $1.7 million in the third quarter of 2024. • Piceance segment adjusted EBITDA totaled $12.8 million, consistent from the second quarter of 2024. Volume throughput decreased 1.7% from the second quarter primarily due to natural production declines and no new wells connected to the system during the quarter. • Barnett segment adjusted EBITDA totaled $7.3 million, an increase of $1.9 million relative to the second quarter of 2024, primarily due to a 26.2% increase in volumes from a customer continuing to increase flow of curtailed volumes and 9 new wells connected to the system from our anchor customer during the quarter. We estimate there is still approximately 20 MMcf/d of shut-in production behind the system. There is currently one rig running and 14 DUCs behind the system. Oil price-driven segments: • Oil price-driven segments generated $33.3 million of combined segment adjusted EBITDA, representing a 9.1% increase relative to the second quarter, and had combined capital expenditures of $8.7 million. • Permian segment adjusted EBITDA totaled $8.5 million, an increase of $0.8 million from the second quarter of 2024, primarily due to 20% increase in volumes shipped on the Double E Pipeline leading to an increase in proportionate adjusted EBITDA from our Double E joint venture. • Rockies segment adjusted EBITDA totaled $24.9 million, an increase of 8.7% relative to the second quarter of 2024, primarily due to increased product margin in the DJ Basin, partially offset by a 6.7% decrease in liquids volume throughput. Operational downtime continued to impact volume throughput in the DJ Basin, however, repairs were completed during the quarter, and all systems have now returned to normal operational capacity. There were 29 new wells connected during the quarter, all in the DJ Basin. There are currently five rigs running and approximately 90 DUCs behind the systems. The following table presents average daily throughput by reportable segment for the periods indicated: Three Months Ended September 30, Nine Months Ended September 30, 2024 2023 2024 2023 Average daily throughput (MMcf/d): Northeast (1) — 752 269 658 Rockies 128 117 127 108 Piceance 284 313 295 299 Barnett 255 170 212 184 Aggregate average daily throughput 667 1,352 903 1,249 Average daily throughput (Mbbl/d): Rockies 70 85 73 76 Aggregate average daily throughput 70 85 73 76 Ohio Gathering average daily throughput (MMcf/d) (2) — 870 283 763 Double E average daily throughput (MMcf/d) (3) 661 327 559 278 _________ (1) Exclusive of Ohio Gathering due to equity method accounting.

(4) Corporate and Other represents those results that are not specifically attributable to a reportable segment or that have not been allocated to our reportable segments, including certain general and administrative expense items and transaction costs. (5) Adjusted EBITDA is a non-GAAP financial measure. Capital Expenditures Capital expenditures totaled $10.9 million in the third quarter of 2024, inclusive of maintenance capital expenditures of $1.3 million. Capital expenditures in the third quarter of 2024 were primarily related to pad connections in the Rockies segment. EXHIBIT 99.1 3

Capital & Liquidity As of September 30, 2024, SMC had $17.8 million in unrestricted cash on hand and $150 million drawn under its $500 million ABL Revolver with $349.2 million of borrowing availability, after accounting for $0.8 million of issued, but undrawn letters of credit. As of September 30, 2024, SMC’s gross availability based on the borrowing base calculation in the credit agreement was $539 million, which is $39 million greater than the $500 million of lender commitments to the ABL Revolver. As of September 30, 2024, SMC was in compliance with all financial covenants, including interest coverage of 2.4x relative to a minimum interest coverage covenant of 2.0x and first lien leverage ratio of 0.8x relative to a maximum first lien leverage ratio of 2.5x. As of September 30, 2024, SMC reported a total leverage ratio of approximately 4.58x. As of September 30, 2024, the Permian Transmission Credit Facility balance was $133.3 million, a reduction of $3.9 million relative to the June 30, 2024 balance of $137.2 million due to scheduled mandatory amortization. The Permian Transmission Term Loan remains non-recourse to SMC. MVC Shortfall Payments SMC billed its customers $5.5 million in the third quarter of 2024 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 third quarter of 2024, SMC recognized $5.5 million of gathering revenue associated with MVC shortfall payments. SMC had no adjustments to MVC shortfall payments in the third quarter of 2024. SMC’s MVC shortfall payment mechanisms contributed $5.5 million of total adjusted EBITDA in the third quarter of 2024. EXHIBIT 99.1 4

Upcoming Investor Conferences Members of SMC's senior management team will attend the 2024 Bank of America Leverage Finance Conference taking place on December 3–4, 2024 and the 2024 Wells Fargo Midstream, Energy, & Utilities Symposium taking place on December 10–11, 2024. The presentation materials associated with these events will be accessible through the Investors section of SMC's website at www.summitmidstream.com prior to the beginning of the conference. 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, segment adjusted EBITDA, Distributable Cash Flow, and Free 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: • the ability of our assets to generate cash sufficient to make future potential cash dividends 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 MVC 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; EXHIBIT 99.1 6
• 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. Free Cash Flow We define free cash flow as distributable cash flow attributable to common and preferred shareholders less growth capital expenditures, less investments in equity method investees, less dividends to common and preferred shareholders. Free cash flow excludes proceeds from asset sales and cash consideration paid for acquisitions. 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.
