Summary

Summary of the 8-K filed September 16, 2026. Cited figures are marked; the original filing is the authoritative source.

Martin Marietta Materials, Inc. (MLM) reported in this Form 8-K, filed September 16, 2026, that on September 15, 2026 it and its wholly owned subsidiary, Martin Marietta Funding LLC (MM Funding), entered into the Eighteenth Amendment to its Credit and Security Agreement with Truist Bank, successor by merger to SunTrust Bank, as administrative agent.

The amendment extends the scheduled maturity of the trade receivables securitization facility to September 15, 2027. The facility is a $500,000,000a trade receivables securitization backed by receivables originated by the Corporation or certain subsidiaries, which are sold or contributed to MM Funding. Subject to conditions, including lender commitments, the facility may be increased to an amount not to exceed $700,000,000.

Effective with the amendment, MM Funding's borrowings bear interest at Adjusted Term SOFR plus 0.700%b, subject to change if the administrative agent determines Adjusted Term SOFR cannot be determined or SOFR no longer reflects the lenders' cost of lending. The agreement includes an amortization event tied to a payment default or acceleration of one of the Corporation's material debt agreements. The full Eighteenth Amendment, including a conformed copy of the Credit and Security Agreement, is filed as Exhibit 10.01 and incorporated by reference.
