On March 16, 2026, MPLX GP LLC, the general partner of MPLX LP, announced the appointment of Erin M. Brzezinski as Vice President and Controller, effective April 1, 2026. This strategic move is aimed at aligning the accounting leadership of MPLX with that of Marathon Petroleum Corporation (MPC), thereby enhancing the integration of financial reporting and technical accounting between the two entities. Brzezinski, who is currently serving as the principal accounting officer of MPC, will take over from Rebecca L. Iten, who will continue in an accounting leadership role within the Partnership. This transition is expected to strengthen the financial oversight and operational execution of MPLX, reflecting a commitment to robust governance and operational efficiency. Brzezinski's extensive experience in accounting, including her previous roles at PricewaterhouseCoopers LLP and Cooper Tire & Rubber Company, positions her well to lead MPLX's financial strategies. The appointment is seen as a positive development for MPLX, likely to enhance investor confidence and support the company's strategic outlook moving forward.
