On March 18, 2025, the Reporting Person filed a Form 4 to report an award of 3,062 common stocks granted on March 14, 2025. But due to administrative error they were reported as being held indirectly by Joint Spousal Trust. The same administrative error was repeated on the Form 4 filed on March 20, 2025. The Form 4 filed on March 18, 2025 has been amended by the Form A filed on April 28, 2025. This Form 4/A amends the Form 4 filed on March 20, 2025, so that such Form 4, as amended, also reflects the 3,062 common stocks directly held by the Reporting Person. | The Reporting Person is a trustee of the Joint Spousal Trust. The Reporting Person and his spouse are the sole beneficiaries of the Joint Spousal Trust. | The price reported in Column 4 is a weighted average price and has been rounded to the nearest cent. These Common Stocks were sold in multiple transactions at prices ranging from $37.40 to $37.41, inclusive. The reporting person undertakes to provide to Summit Midstream Corporation, any security holder of Summit Midstream Corporation, or the staff of the Securities and Exchange Commission, upon request, full information regarding the number of Common Stocks sold at each separate price within the ranges set forth in footnote 2 to this Form 4.
