Outlook, Risks, and Management Commentary
The new credit agreement is intended for general partnership purposes. The filing notes that the preliminary cash balance of $1.5 billion does not present all information necessary for a full understanding of the results of operations for the quarter ended March 31, 2026.

Certain lenders to the new facility have historically provided and may continue to provide investment banking and financial advisory services to MPLX.
