Insights

Corporate Governance Analyst

Routine director deferred-compensation accrual; limited market impact.

The filing records a 10/01/2025 accrual of 78.629 phantom stock units for director Carolyn K. Pittman under the non-employee director deferred compensation plan. Each unit equals one share but is contractually payable in cash upon termination of service, so no new shares will be issued from this accrual.

Because the units settle in cash and the amount is small relative to total outstanding shares, this disclosure appears procedural and is unlikely to be material to MTXs capital structure or near-term trading.
