Martin Marietta Lands New $1.5 Billion Revolving Credit Facility with JPMorgan

Martin Marietta Materials Inc., a leading supplier of aggregates for construction projects, has secured a $1.5 billion senior unsecured revolving credit facility from JPMorgan Chase Bank. This new agreement replaces the company's previous five-year revolving credit facility with JPMorgan, which was terminated on August 18, 2026.

The new facility will bear interest at either Term SOFR or a base rate plus a ratings-based margin and will mature on August 18, 2031. The agreement includes leverage covenants that provide temporary step-ups following the Lhoist North America acquisition to offer integration flexibility.
