How do these executive compensation changes at MPC directly affect MPLX unitholders?

While these changes are at MPC, the executives who manage and operate MPLX's business are employed by MPC. Therefore, these compensation adjustments reflect the leadership and incentive structures of the management team responsible for MPLX's strategic decisions and operational execution, which can indirectly impact MPLX's performance and value.

What is the significance of Ms. Mannen receiving a one-time long-term incentive award?

The one-time LTI award is a retention and incentive tool designed to recognize and reward Ms. Mannen for taking on the critical role of CEO and to align her interests with the long-term performance of MPC, and by extension, MPLX. It's an additional incentive beyond her base salary and annual bonus.

Why has Mr. Hennigan's base salary been reduced?

Mr. Hennigan's base salary reduction is associated with his transition from CEO to Executive Chairman. This role change typically involves a shift in responsibilities and potentially a different compensation philosophy, often reflected in a lower base salary but continued strategic involvement and eligibility for incentive programs.

Where can I find more detailed information about MPC's ACB and LTI award programs?

Detailed descriptions of MPC's Annual Cash Bonus (ACB) and Long-Term Incentive (LTI) award programs are available in MPLX's Annual Report on Form 10-K for the year ended December 31, 2023, which is filed with the SEC.
