Summit Midstream Corporation Reports First Quarter 2026 Financial and Operating Results

, /PRNewswire/ -- Summit Midstream Corporation (NYSE: SMC) ("Summit", "SMC" or the "Company") announced today its financial and operating results for the three months ended March 31, 2026. Highlights First quarter 2026 net loss of $3.2 million, Adjusted EBITDA of $54.2 million, cash flow available for distributions ("Distributable Cash Flow" or "DCF") of $26.9 million and free cash flow ("FCF") of $11.4 million Connected 37 wells during the first quarter, including four Williston wells from the new 10-year crude gathering agreement; five rigs currently running with approximately 80 DUCs behind the systems Executed a new precedent agreement for 100 MMcf/d of firm capacity on the Double E Pipeline, with Q1 2027 expected in-service date and 10-year term Repaid all $45 million of accrued Series A Preferred Stock dividends clearing a key milestone toward reinstating a common dividend Completed a $42 million private placement of common stock to an affiliate of Tailwater Capital LLC, Summit's largest shareholder, providing additional financial flexibility to execute on high-return growth projects and reduce ABL borrowings Reiterating 2026 full-year Adjusted EBITDA guidance of $225 million to $265 million, supported by accelerating producer activity in the Rockies and anticipated Mid-Con volume ramp Management Commentary Heath Deneke, President, Chief Executive Officer and Chairman, commented, "First quarter results reflected favorable crude oil prices primarily impacting our Rockies segment, offset by lower realized residue gas prices and lower than expected volumes in the Mid-Con Segment. We continue to expect the business to trend toward the midpoint of our original guidance range and are seeing a lot of momentum across our portfolio, particularly in the Permian and Rockies segments. "Subsequent to quarter end, Double E executed another new 10-year take-or-pay precedent agreement for 100 MMcf/d of firm capacity behind an operational processing plant in Eddy County, New Mexico, with the lateral connecting the plant expected to be in-service in the first quarter of 20271. This agreement, along with those previously announced, brings total contracted volume on Double E to 1.755 Bcf/d, and we remain encouraged by the continued commercial progress on the pipeline. We are evaluating significant shipper interest in the recently launched open season, and remain optimistic there will be sufficient commercial support to make a final investment decision on the approximately 800 MMcf/d mid-point compression expansion project. "In the Rockies Segment, the favorable crude oil price environment is expected to improve our product margin over the coming quarters and several customers are actively working to accelerate and increase activity beyond our original expectations. We are also encouraged by the preliminary results of four wells behind the new Williston Basin commercial contract we secured last quarter. We have 40 new wells expected across the portfolio in the second quarter, including 20 in the Mid-Con segment." __________________________ 1 The agreement is contingent upon satisfaction of certain customary conditions, including Double E board approval. First Quarter 2026 Business Highlights SMC's average daily natural gas throughput on its wholly owned, operated systems decreased 2.7% to 870 MMcf/d, while liquids volumes decreased 3.0% to 64 Mbbl/d, relative to the fourth quarter of 2025. Double E Pipeline averaged 805 MMcf/d and contributed $8.7 million in Adjusted EBITDA, net to SMC, for the first quarter of 2026. Natural gas price-driven segments: Natural gas price-driven segments generated $28.9 million in combined Segment Adjusted EBITDA, a $2.6 million decrease relative to the fourth quarter of 2025, with combined capital expenditures of $7.6 million Mid-Con Segment Adjusted EBITDA totaled $19.3 million, a decrease of $2.1 million relative to the fourth quarter of 2025, primarily due to lower natural gas throughput as a result of natural production declines, partially offset by six new Arkoma well connections. Subsequent to quarter end, three additional Arkoma wells were connected to the system and there are currently 17 Barnett DUCs expected to come online in the second quarter of 2026. Piceance Segment Adjusted EBITDA totaled $9.6 million, a decrease of $0.4 million relative to the fourth quarter of 2025, primarily due to a 7.3% decline in volume throughput driven by temporary shut-ins of approximately 8.0 MMcf/d, natural production declines, and no new well connections during the quarter. Customers currently have ~20 MMcf/d of natural gas shut-in as a result of low regional gas prices. Based on current forecasted prices in the region, we expect this production to resume beginning in the third quarter of 2026. Oil price-driven segments: Oil price-driven segments generated $35.1 million in combined Segment Adjusted EBITDA, a $1.5 million decrease relative to the fourth quarter of 2025, with combined capital expenditures of $11.0 million Rockies Segment Adjusted EBITDA totaled $26.4 million, a decrease of $1.5 million relative to the fourth quarter of 2025, driven by a $1.2 million non-cash imbalance, lower realized residue gas prices negatively impacting percent-of-proceeds contracts and lower fresh water sales, partially offset by a 4.4% increase in natural gas volume throughput and higher realized crude oil and NGL prices beginning in March 2026. 18 wells were connected in the DJ Basin and 13 in the Williston Basin, including the first four 3-mile lateral wells under the new 10-year crude gathering agreement. Five rigs are currently running with approximately 60 DUCs behind the system. Permian Segment Adjusted EBITDA totaled $8.7 million, flat relative to the fourth quarter of 2025.

Capital & Liquidity As of March 31, 2026, SMC had $43.4 million in unrestricted cash on hand and $116 million drawn under its $500 million ABL Revolver with $381 million of borrowing availability, after accounting for $2.7 million of issued, but undrawn letters of credit. As of March 31, 2026, SMC's gross availability based on the borrowing base calculation in the credit agreement was $802 million, which is $302 million greater than the $500 million of lender commitments to the ABL Revolver. As of March 31, 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 0.4x relative to a maximum first lien leverage ratio of 2.5x. As of March 31, 2026, SMC reported a total leverage ratio of approximately 4.2x. During the first quarter, Summit Permian Transmission, LLC entered into a new $440 million senior secured term facility, which includes a $50 million committed accordion feature and a $50 million uncommitted accordion feature (the "Term Facility") maturing in March 2031. Proceeds from the Term Facility were used to refinance Summit Permian Transmission's existing credit facility, redeem Summit Permian Transmission Holdco's preferred units, fund an $85 million restricted payment to SMC, provide liquidity to fund SMC's share of capital expenditures including those associated with the recently announced expansion projects, and pay other fees and expenses. As of March 31, 2026, the Summit Permian Transmission Term Loan Facility had a balance of $340 million. Summit Midstream Permian has $6.1 million of cash-on-hand as of March 31, 2026. The Permian Transmission Term Loan remains non-recourse to SMC. MVC Shortfall Payments SMC billed its customers $4.1 million in the first 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 first quarter of 2026, SMC recognized $4.1 million of gathering revenue associated with MVC shortfall payments. SMC had no adjustments to MVC shortfall payments in the first quarter of 2026. SMC's MVC shortfall payment mechanisms contributed $4.1 million of total Adjusted EBITDA in the first quarter of 2026.

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. 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; 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.
