The Purchase Agreement contained customary representations, warranties, covenants, conditions to closing, and termination provisions.

The closing of the transactions (the "Closing") contemplated by the Purchase Agreement (the "Transactions") occurred on March 31, 2026.

A total of 1,351,351 shares of Common Stock were issued at the Closing pursuant to the Purchase Agreement.

The Shares are subject to a 6-month lock up period and other terms and conditions. The Purchase Agreement and the Transactions were unanimously approved by the Audit Committee of the Board of Directors of the Company, which is comprised solely of independent and disinterested directors.

The Purchase Agreement amends and modifies the Investor and Registration Rights Agreement, dated December 2, 2024 (the "IRRA"), by and among the Company, Tall Oak Midstream Holdings, Connect Midstream and Tall Oak Midstream Investments, LLC, a Delaware limited liability company, such that the Shares issued to Tall Oak Midstream Holdings (or its designated members) constitute "Registerable Securities" under the IRRA, and, pursuant to the terms of the Purchase Agreement and the IRRA, the Company will use commercially reasonable efforts to prepare and file a Registration Statement (as defined in the IRRA) with the SEC (or amend by post-effective amendment a previously filed Registration Statement, covering the resale of all of the Shares for an offering to be made on a continuous basis pursuant to Rule 415 under the Securities Act of 1933, as amended (the "Securities Act"), within 90 days of the Closing.

Tall Oak Midstream Holdings and Connect Midstream are affiliates of Tailwater Capital LLC ("Tailwater"). As of the date of the Purchase Agreement and prior to the Closing, affiliates of Tailwater beneficially owned approximately 35% of the outstanding voting power of the Company. Four of the directors on the Board of Directors of the Company are affiliates of Tailwater. Following the transactions, Tailwater and its affiliated entities beneficially own approximately 39% of Summit's outstanding equity.

The foregoing descriptions of the Purchase Agreement and the IRRA do not purport to be complete and are subject to, and qualified in their entirety, as applicable, by, (i) the full text of the Purchase Agreement, which is filed as Exhibit 10.1 to this Current Report on Form 8-K, and (ii) the full text of the IRRA, which is incorporated in this Current Report on Form 8-K by reference to Exhibit 10.2 filed with the Company's Current Report on Form 8-K filed with the SEC on December 3, 2024.

**Item 3.02. Unregistered Sales of Equity Securities.**

The disclosure set forth in Item 1.01 above is incorporated into this Item 3.02 by reference. The Shares were issued in reliance on the exemption from registration requirements under the Securities Act, pursuant to Section 4(a)(2) thereof.

**Item 7.01. Regulation FD Disclosure.**

On March 31, 2026, the Company issued a press release announcing the signing of the Purchase Agreement. The full text of the press release is attached as Exhibit 99.1 to this Current Report on Form 8-K and is incorporated herein by reference.

**Summit Midstream Corporation Announces $42 Million Equity Issuance to Affiliate of Tailwater Capital**

Summit Midstream Corporation (NYSE: SMC) ("Summit", "SMC" or the "Company") announced today that it and its subsidiary, Summit Midstream Partners, LP (the "Partnership"), have entered into a securities purchase agreement with an affiliate of Tailwater Capital LLC ("Tailwater"), for a private placement of 1,351,351 shares of the Company's common stock, at a price of $31.08 per share. The investment strengthens Summit's balance sheet and provides capital to fund the Company's strategic growth initiatives and general corporate purposes.

"We are pleased to expand our relationship with Tailwater Capital through this equity issuance," said Heath Deneke, President, Chief Executive Officer and Chairman of Summit. "This $42 million investment represents a significant vote of confidence in our company's outlook and provides us with financial flexibility to execute on our current pipeline of high-return growth projects while continuing to make progress towards achieving our long-term 3.5x leverage target."

Pursuant to the securities purchase agreement, Summit will issue 1,351,351 shares of its common stock at a price per share of $31.08 to raise $42.0 million for debt reduction and to fund growth capital. The $31.08 price per share represents the closing price as of March 30, 2026. The shares are subject to a 6-month lock up period and other terms and conditions. The transaction was unanimously approved by the Audit Committee of the Board of Directors, which is comprised solely of independent and disinterested directors.

"As Summit's largest shareholder, we are excited to continue to provide support as the Company enters an exciting phase of organic growth execution around its portfolio, all of which continue to benefit from strong secular tailwinds for U.S. natural gas and crude oil outlook. Summit remains well-positioned to build momentum around its recently announced growth projects and provide best-in-class infrastructure solutions to its customer base," said Jason Downie, Co-founder & Managing Partner at Tailwater Capital. "We value our long-term partnership with Summit and look forward to continued execution across its strategic and financial priorities."

Following the transactions, Tailwater and its affiliated entities are expected to beneficially own approximately 39% of Summit's outstanding equity. Summit intends to use the net proceeds from the private placement to reduce borrowings under the Company's asset-based lending credit facility and fund organic growth capital projects across its operating areas.

Summit is represented in the transactions by Troutman Pepper Locke LLP. Tall Oak Midstream Holdings and Tailwater are represented in the transactions by Kirkland & Ellis LLP.
