Summit Midstream Corporation Reports Second Quarter 2026 Financial and Operating Results
Houston, Texas (August 10, 2026) – Summit Midstream Corporation (NYSE: SMC) (“Summit”, “SMC” or the “Company”) announced today its financial and operating results for the three months ended June 30, 2026.
Highlights
Second quarter 2026 net income of $4.6 million, Adjusted EBITDA of $60.7 million, an increase of 12% relative to the first quarter of 2026, cash flow available for distributions (“Distributable Cash Flow” or “DCF”) of $36.8 million and free cash flow (“FCF”) of $9.4 million
Eight rigs currently operating behind the Rockies systems, including six in the Williston Basin and two in the DJ Basin, with approximately 75 DUCs across the footprint
Mid-Con Segment natural gas volume throughput increased 9.9% to 523 MMcf/d relative to the first quarter of 2026, driving a 10% increase in Segment Adjusted EBITDA
Established $35 million stock repurchase program
Continued commercial progress in the Permian and Williston Basins, including new firm transportation agreements on Double E and a new crude gathering agreement in Divide County, North Dakota
Tightened 2026 Adjusted EBITDA guidance range to $235 million to $255 million and increased total capital expenditures to $100 million to $120 million to reflect additional high-returning growth projects in the Rockies and Permian Segments
Management Commentary
Heath Deneke, President, Chief Executive Officer and Chairman, commented, "Customer activity ramped up meaningfully across our footprint during the second quarter with 36 new well connections, driving a 12% increase in Adjusted EBITDA relative to the first quarter. Our Rockies Segment accounted for the majority of the increase, while Mid-Con delivered a nearly 10% volume increase on strong well performance in both the Barnett and Arkoma, giving us added confidence in the segment's trajectory for the remainder of the year. We also executed new firm transportation agreements on Double E and a new crude gathering agreement in Divide County, North Dakota, further strengthening our long-term growth outlook. We continue to have a tremendous amount of customer interest in the ongoing Double E – Mainline Compression Expansion open season. We have extended the open season through the end of August as we work on finalizing additional firm transportation agreements to support the project and we expect to be in a position to make a final investment decision prior to its conclusion.
"Another encouraging development this quarter has been the acceleration of activity in the Williston Basin. Six rigs are running behind our system today, the most active drilling program we have seen in the basin in several years. Since the end of the second quarter, we have connected 17 new wells, nine of which we serve with both crude oil and produced water gathering. We’ve also identified approximately 30 incremental well connections in the Williston Basin that were not part of our original plan, a result of our recent commercial success in the basin and existing customers accelerating their development activity. These wells are expected to connect primarily in the fourth quarter, so we expect minimal impact on 2026 results, but they position us well for a strong start to 2027.
"With a solid first half behind us and customer activity accelerating across the footprint, we have better visibility into our second-half volume profile. We are tightening our full-year 2026 Adjusted EBITDA guidance to $235 million to $255 million and increasing total capital expenditures, including Double E, to $100 million to $120 million to reflect additional high-returning growth projects in the Rockies and Permian Segments.”
Second Quarter 2026 Business Highlights
SMC's average daily natural gas throughput on its wholly owned, operated systems increased 3.3% to 899 MMcf/d, while liquids volumes increased 6.3% to 68 Mbbl/d, relative to the first quarter of 2026. Double E Pipeline averaged 859 MMcf/d and contributed $9.4 million in Adjusted EBITDA, net to SMC, for the second quarter of 2026.

Natural gas price-driven segments:
Natural gas price-driven segments generated $30.0 million in combined Segment Adjusted EBITDA, a $1.1 million increase relative to the first quarter of 2026, with combined capital expenditures of $7.3 million
Mid-Con Segment Adjusted EBITDA totaled $21.4 million, an increase of $2.0 million relative to the first quarter of 2026, primarily due to a 9.9% increase in natural gas volume throughput to 523 MMcf/d, driven by 17 new Barnett well connections and three new Arkoma well connections during the quarter.
Piceance Segment Adjusted EBITDA totaled $8.7 million, a decrease of $0.9 million relative to the first quarter of 2026, primarily due to a 5.7% decline in volume throughput driven by continued temporary shut-ins, natural production declines, and no new well connections during the quarter. As of the end of July, all previous shut-in production has resumed flowing.
Oil price-driven segments:
Oil price-driven segments generated $39.7 million in combined Segment Adjusted EBITDA, a $4.6 million increase relative to the first quarter of 2026, with combined capital expenditures of $17.0 million
Rockies Segment Adjusted EBITDA totaled $30.4 million, an increase of $4.0 million relative to the first quarter of 2026, driven by a 6.3% increase in liquids volume throughput and higher realized crude oil and NGL prices, partially offset by a 3.0% decline in natural gas volume throughput. 16 wells were connected in the DJ Basin during the quarter, and subsequent to quarter end, 17 wells were connected in the Williston Basin, including nine wells for which we provide both crude oil and produced water gathering services. Eight rigs are currently running in the Rockies Segment, including two in the DJ Basin and six in the Williston Basin, with approximately 75 DUCs behind the systems.
Permian Segment Adjusted EBITDA totaled $9.4 million, an increase of $0.6 million relative to the first quarter of 2026, driven by a 6.7% increase in Double E volume throughput to 859 MMcf/d.

EXHIBIT 99.1
Capital & Liquidity
As of June 30, 2026, SMC had $21.0 million in unrestricted cash-on-hand and $79 million drawn under its $500 million ABL Revolver with $418 million of borrowing availability, after accounting for $2.7 million of issued, but undrawn letters of credit. As of June 30, 2026, SMC’s gross availability based on the borrowing base calculation in the credit agreement was $798 million, which is $298 million greater than the $500 million of lender commitments to the ABL Revolver. As of June 30, 2026, SMC 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 0.3x relative to a maximum first lien leverage ratio of 2.5x. As of June 30, 2026, SMC reported a total leverage ratio of approximately 4.1x.
As of June 30, 2026, the Summit Permian Transmission Term Loan Facility had a balance of $350 million. Summit Midstream Permian has $10.8 million of cash-on-hand as of June 30, 2026. The Permian Transmission Term Loan remains non-recourse to SMC.
MVC Shortfall Payments
SMC billed its customers $4.2 million in the second quarter of 2026 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 2026, SMC recognized $4.2 million of gathering revenue associated with MVC shortfall payments. SMC had $0.0 million of adjustments to MVC shortfall payments in the second quarter of 2026. SMC’s MVC shortfall payment mechanisms contributed $4.2 million of total Adjusted EBITDA in the second quarter of 2026. The minimum volume commitments underpinning SMC's Piceance segment gathering agreements, which represent substantially all of SMC's MVC shortfall payments, expire at the end of the third quarter of 2026.
Quarterly Dividend
The Board of Directors of Summit Midstream Corporation continued to suspend cash dividends payable on the common stock for the period ended June 30, 2026. The quarterly cash dividend on the Series A Preferred Stock, for the period ending September 14, 2026, will be paid to preferred shareholders of record as of the close of business on September 1, 2026.
Share Repurchase Program
During the second quarter of 2026, SMC repurchased 34,624 shares of its common stock for approximately $1.0 million. As of June 30, 2026, SMC had approximately $34.0 million of remaining capacity under its $35 million share repurchase program.

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, share-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.
4

EXHIBIT 99.1
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) the impact of the timing of MVC shortfall payments under our gathering agreements or (ii) 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:
adjusted EBITDA includes the Company's proportionate share of Adjusted EBITDA from its unconsolidated equity method investee. Because this entity is not consolidated, the Company does not control its operations and does not have legal claim to its revenues, expenses, assets, liabilities, or cash flows, other than distributions received. As a result, this adjustment has limitations as an analytical measure and may not be comparable to similarly titled measures presented by other companies;
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.
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.
