**Summit Midstream Corporation Announces Inaugural $35 Million Stock Repurchase Program**

Houston, Texas (June 1, 2026) – Summit Midstream Corporation (NYSE: SMC) ("Summit," "SMC" or the "Company") today announced that its Board of Directors has authorized the Company's inaugural stock repurchase program to repurchase up to $35 million of the Company's outstanding common stock.

Heath Deneke, President, Chief Executive Officer and Chairman, commented, "The authorization of our inaugural share repurchase program reflects the Board's confidence in Summit's financial strength and the significant progress we have made over the past year in simplifying our balance sheet and strengthening our platform. Having repaid all arrears on our Series A Preferred Stock and supported by our improving free cash flow profile and financial flexibility, we are now in a position to utilize a common stock buy program as a tool to ensure liquidity and support the secondary market of the shares. We believe our common stock represents an attractive opportunity at current levels, and we intend to be opportunistic in executing any repurchases."

Under the program, repurchases of shares of the Company's common stock may be made from time to time in the open market, through privately negotiated transactions, block purchases, or otherwise, including through a Rule 10b5-1 trading plan, in compliance with applicable federal and state securities laws, including Rule 10b-18 under the Securities Exchange Act of 1934, as amended. The timing and amount of any repurchases will be determined by management at its discretion based on a variety of factors, including business and market conditions, the trading price of the Company's common stock, compliance with debt covenants, and certain other considerations. The program does not obligate the Company to repurchase any specific number of shares, has no fixed expiration date, and may be suspended or discontinued at any time.
