Item 5.02. Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangement of Certain Officers.

On May 28, 2024, the Board of Directors of the general partner (the “General Partner”) of Black Stone Minerals, L.P. (the “Partnership”) and Evan Kiefer, Senior Vice President, Chief Financial Officer, and Treasurer of the General Partner, agreed that Mr. Kiefer would depart his current roles at the general partner effective May 28, 2024. Mr. Kiefer is expected to enter into a separation, release, and consulting agreement with the Partnership.

The Board of Directors has appointed Taylor DeWalch as Senior Vice President and Chief Financial Officer of the General Partner and Dawn Smajstrla as Treasurer of the General Partner, effective May 28, 2024. Mr. DeWalch, 35, has over 12 years of experience in the oil and gas industry, mostly as an engineer. He joined the Partnership in February 2023 as Director, Strategy & Asset Development and was promoted to Vice President, Corporate Strategy & Development of the general partner in February 2024. Mr. DeWalch worked as a Senior Reservoir Engineer at Callon Petroleum, Inc. from 2022 until he joined Black Stone. He had previously served in multiple roles at Unitex Oil and Gas from 2018 to 2022, including Vice President of Reservoir Engineering, and in various engineering capacities at Anadarko Petroleum from 2012 to 2018. He graduated from Louisiana State University with a Bachelor’s in Petroleum Engineering. In connection with his appointment, Mr. DeWalch’s base pay was increased to $310,000, and his weighted-average short-term-incentive target was adjusted to approximately $250,000. Mr. DeWalch is the son of Mark DeWalch, a director of the General Partner.

The Partnership expects that Mr. DeWalch will enter into a severance agreement with Black Stone Natural Resources Management Company, in a form substantially similar to those entered into by the other Senior Vice Presidents, Carrie Clark and Steve Putman. That agreement will provide for the payment of cash severance payments and benefits in the event Mr. DeWalch’s employment is terminated under certain circumstances, but he has not yet entered into the agreement.




Pursuant to the requirements of the Securities Exchange Act of 1934, the registrant has duly caused this report to be signed on its behalf by the undersigned hereunto duly authorized.
