MPLX LP 8-K Report, Material Agreement (Apr 13, 2026)

MPLX LP has entered into a new $2.5 billion, five-year unsecured revolving credit facility, replacing its previous agreement. This new facility, effective April 7, 2026, matures on April 7, 2031, and provides MPLX with significant financial flexibility for general partnership purposes. Notably, there were no outstanding borrowings under the prior agreement, and none are currently drawn under the new facility, indicating a strong liquidity position. MPLX also holds $1.5 billion in cash and cash equivalents as of March 31, 2026. The agreement allows for an optional increase of up to $1.0 billion in commitments and offers flexibility for maturity date extensions. It includes sub-facilities for swing-line loans and letters of credit. Covenants within the agreement, such as a debt-to-EBITDA ratio not exceeding 5.0x (or 5.5x during acquisitions), are considered customary and designed to maintain financial discipline. This proactive refinancing strengthens MPLX's balance sheet and demonstrates its commitment to ensuring robust access to capital.
