ACQUISTIONS AND DIVESTITURES | 3. ACQUISITIONS AND DIVESTITURES Moonrise Acquisition. On March 10, 2025, the Company completed the transaction contemplated in the Membership Interest Purchase Agreement, dated as of March 10, 2025, by and among the Company, Summit Holdings, Fundare Resources Company HoldCo, LLC, a Delaware limited liability company (“Fundare”), and solely for purposes of Section 9.19 thereto, Fundare Resources Company, LLC, a Delaware limited liability company, pursuant to which Fundare contributed all of its equity interests in Moonrise Midstream, LLC, a Delaware limited liability company (“Moonrise”), to Summit Holdings in exchange for total consideration equal to approximately $90.0 million (the “Moonrise Acquisition”). Total consideration consisted of (i) a $70.0 million cash payment and (ii) the issuance of 462,265 shares of common stock of the Company. The fair values of certain assets and liabilities, including property, plant and equipment, and other intangible assets required the use of significant judgments and estimates. The following table sets forth the preliminary fair value of the assets acquired and liabilities assumed as of the acquisition date. Certain data and assessments necessary to complete the purchase price allocation are still under evaluation, including, but not limited to, the valuation of property, plant and equipment, and intangible assets. The Company will finalize the purchase price allocation during the twelve-month period following the acquisition date, during which time the value of the assets and liabilities may be revised as appropriate.

(1) Purchase price consideration includes $17.9 million of equity consideration (462,265 shares valued at $38.71 per share on March 10, 2025) as well as $1.9 million of cash acquired. The assets acquired and liabilities assumed were recorded at their preliminary estimated fair values at the date of the acquisition. Acquired working capital amounts are expected to approximate fair value due to their short-term nature. The valuation of certain assets, including property, are based on preliminary appraisals. The fair value of acquired equipment is based on both available market data and cost and income approaches. These methods are considered Level 3 fair value estimates and include significant assumptions of future gathering and processing volumes, commodity prices, and operating and capital cost estimates, discounted using a weighted average cost of capital. Intangible assets acquired consist of rights-of-way with a weighted average amortization period of approximately 30 years. Subsequent to the Moonrise Acquisition, during the second quarter of 2025, the Company integrated the Moonrise assets within its Niobrara G&P system. As a result of the integration, it is impracticable to disclose the amounts of revenues and earnings that the Moonrise Acquisition contributed to the Company’s consolidated statements of operations during the reporting period. Tall Oak Business Contribution Agreement.

Sale of Summit Utica Sale. On March 22, 2024, SMLP completed the disposition of Summit Midstream Utica, LLC (“Summit Utica”) to a subsidiary of MPLX LP for a cash sale price of $625.0 million, subject to customary post-closing adjustments (the “Utica Sale”). Summit Utica was the owner of (i) approximately 36% of the issued and outstanding equity interests in Ohio Gathering Company, L.L.C. (“OGC”), (ii) approximately 38% of the issued and outstanding equity interests in Ohio Condensate Company, L.L.C. (“OCC” and, together with OGC, “Ohio Gathering”) and (iii) midstream assets located in the Utica Shale. Ohio Gathering was the owner of a natural gas gathering system and condensate stabilization facility located in Belmont and Monroe counties in the Utica Shale in southeastern Ohio. During the quarterly period ended March 31, 2024, the Company recognized a total gain on the disposition of Summit Utica of $212.5 million based on total cash proceeds received of $625.0 million and net assets sold of $412.5 million. A portion of the cash proceeds was used to reduce amounts outstanding under the Company’s existing asset-based revolving credit facility and pay the costs and expenses in connection with the 2026 Secured Notes Asset Sale Offer (as defined herein) (see Note 8 - Debt, for additional information). The purchase and sale agreement for the sale of Summit Utica did not discretely list values for OGC, OCC or SMLP’s midstream assets located in the Utica Shale. Using fair value methods allowed by GAAP, the Company derived a fair value estimate for the disposed assets and then determined the appropriate gain recognition amount for each disposal to include in its consolidated financial statements. The estimated fair values were determined utilizing a discounted cash flow technique based on estimated revenues, costs, capital expenditures, and an appropriate discount rate. Given the unobservable nature of the inputs, the fair value measurement is deemed to use Level 3 inputs. Based on these fair values, the Company recognized a gain on the disposition of the Utica midstream business of $85.6 million, which is recorded within gain on sale of business in the Company’s consolidated statements of operations, and a gain of $126.3 million related to the disposition of Ohio Gathering, which is recorded within gain on sale of Ohio Gathering in the Company’s consolidated statements of operations. Sale of Mountaineer Midstream System. On May 1, 2024, SMLP completed the sale of its Mountaineer Midstream Company, LLC (“Mountaineer Midstream”) system, to Antero Midstream LLC for a cash sale price of $70.0 million, subject to customary post-closing adjustments (the “Mountaineer Transaction”). Mountaineer Midstream was the owner of midstream assets located in the Marcellus Shale. Prior to closing the Mountaineer Transaction, SMLP sold related compression assets located in the Marcellus Shale to a compression service provider for cash consideration of approximately $5 million in April 2024. During the year ended December 31, 2024, the Company recognized an impairment of $68.0 million in connection with the Mountaineer Transaction and the sale of compression assets based on their estimated fair value and net assets of approximately $143.0 million.
