Summary

Summary of the 8-K filed August 18, 2026. Cited figures are marked; the original filing is the authoritative source.

On August 18, 2026, Martin Marietta Materials, Inc. entered into a Credit Agreement with JPMorgan Chase Bank, N.A., as administrative agent, providing for a $1.5 billiona five-year senior unsecured revolving facility.

Borrowings bear interest at Term SOFR or a base rate, plus a margin set by a ratings-based pricing grid. The facility replaces the company's existing Credit Agreement dated December 21, 2021, under which no borrowings were outstanding before the new agreement. The new facility expires on August 18, 2031.

The agreement contains a maximum Leverage Ratio covenant of 3.75:1.00, with step-ups tied to the previously announced acquisition of Lhoist North America, Inc. (the "Acquisition"). After the Acquisition closes, the ratio may not exceed 4.75:1.00 for the first three fiscal quarters, 4.25:1.00 for the next three, and 3.75:1.00 thereafter. Debt incurred for certain acquisitions may be excluded for four quarters if the ratio without the exclusion does not exceed 4.25:1.00.

Cash and cash equivalents may reduce consolidated debt for the ratio calculation, up to $500 millionb, if no amounts are outstanding under both the Revolving Facility and the accounts receivable securitization facility. The filing also reports the Credit Agreement as Exhibit 10.1 and the cover page in Inline XBRL as Exhibit 104. It was signed by George Schoen, Executive Vice President, General Counsel and Corporate Secretary.
