Summary

Summary of the 8-K filed February 13, 2026. Cited figures are marked; the original filing is the authoritative source.

Martin Marietta Materials, Inc. filed this Form 8-K under Item 1.04 (Mine Safety – Reporting of Shutdowns and Patterns of Violations).

The filing reports that on February 11, 2026, the company received a section 107(a) imminent-danger order from the Mine Safety and Health Administration (MSHA) at its Kokomo Quarry in Kokomo, Indiana. The order stated that a miner was standing on an elevated crusher platform being constructed about 10 feet off the ground. Although the miner was wearing fall protection, the miner was not anchored to an effective position to prevent a danger of falling, which exposed the miner to risk of injury.

The filing states that corrective action was taken, that no one was injured in the cited incident, and that the order has been terminated. For investors, this is a limited safety-compliance disclosure. The filing reports no injuries, no operational shutdown beyond the order itself, and no financial impact, and it does not state any monetary penalty.
