MPLX substantially increased capital expenditures while strengthening its balance sheet through new debt issuance and higher cash positions.

The company is in an active investment phase, with capital expenditures growing substantially as it expands midstream infrastructure, particularly in the Permian to Gulf Coast value chain. The February 2026 debt issuance of $1.5 billion in long-term senior notes provides financial flexibility to fund this expansion while maintaining strong liquidity.
