Appointment of Principal Financial Officer
On December 21, 2023, the board of directors (the “Board”) of MPLX GP LLC ("MPLX"), the general partner of MPLX LP, appointed C. Kristopher Hagedorn as Executive Vice President and Chief Financial Officer, effective January 1, 2024. In this capacity, Mr. Hagedorn will be MPLX’s principal financial officer. Mr. Hagedorn will succeed John J. Quaid, who will cease to serve as Executive Vice President and Chief Financial Officer of MPLX effective January 1, 2024 to accept a role as Executive Vice President and Chief Financial Officer of Marathon Petroleum Corporation (“MPC”).
Mr. Hagedorn, 47, also currently serves as Senior Vice President and Controller of MPC, a position he has held since September 2021. Prior to this appointment, he served as MPLX’s Vice President and Controller since October 2017. Before joining MPLX, he was Vice President and Controller at CONSOL Energy Inc., a Pennsylvania-based natural gas and coal producer and exporter, beginning in 2015, Assistant Controller beginning in 2014 and Director, Financial Accounting, beginning in 2012. Mr. Hagedorn was Chief Accounting Officer for CONE Midstream Partners LP, a publicly traded master limited partnership with gathering assets in the Appalachian Basin, from 2014 to 2015. Previously, he served in positions of increasing responsibility with PricewaterhouseCoopers LLP beginning in 1998.
MPLX does not directly employ any of the personnel responsible for managing and operating its business. Rather, MPLX contracts with MPC to provide the necessary personnel, all of whom are directly employed by MPC or one of its affiliates. Mr. Hagedorn's annual base salary from MPC is $450,000, and his target bonus opportunity under MPC’s annual cash bonus (“ACB”) program is equal to 60% of his base salary. His actual bonus will be based on performance relative to the performance goals established under the ACB program. Mr. Hagedorn's target award value under MPC’s long-term incentive (“LTI”) program was $500,000 for 2023. Descriptions of the ACB and LTI programs are included in MPLX’s Annual Report on Form 10-K for the year ended December 31, 2022 (the “2022 10-K”). Any changes to Mr. Hagedorn's compensation resulting from his appointment as MPLX’s Executive Vice President and Chief Financial Officer will be determined in due course by the Compensation and Organization Development Committee of MPC’s Board of Directors during its annual compensation review process in early 2024.
Mr. Hagedorn will also be eligible to participate in MPC’s other benefit plans and programs such as health and life insurance, income protection in a circumstance of long-term and short-term disability and retirement and severance benefits plans, descriptions of which are included in the 2022 10-K.
Appointment of Director
On December 21, 2023, the board of managers of MPC Investment LLC, the sole member of MPLX, appointed Mr. Hagedorn to serve as a member of the Board, effective January 1, 2024, and fixed the size of the Board at ten members, effective as of the same date. Mr. Hagedorn is not expected to serve on any standing committees of the Board. As an officer of MPLX, Mr. Hagedorn will not receive compensation for his services as a member of the Board.
Other than with respect to the employment relationship and compensation matters described above, there are no arrangements or understandings between Mr. Hagedorn and any other persons pursuant to which Mr. Hagedorn was appointed MPLX’s Executive Vice President and Chief Financial Officer or as a member of the Board. There are no family relationships between Mr. Hagedorn and any director or executive officer of MPLX, and Mr. Hagedorn has no direct or indirect interest in any transaction or proposed transaction required to be disclosed pursuant to Item 404(a) of Regulation S-K.
