• Risks related to Defaulting Lenders, which could lead to reallocation of Letter of Credit Liabilities or requirements for the Borrower to Cash Collateralize obligations.

• Compliance risks with Anti-Corruption Laws, Sanctions, and Anti-Money Laundering Laws, which could result in penalties or reputational damage.

Recommendation

This filing represents a routine and positive financial management action by Martin Marietta Materials, Inc. The extension of its $800 million credit facility and the adjustment of financial covenants enhance the company's liquidity and operational flexibility.
