Powell Industries' compensation committee approved restricted stock unit awards for CEO Brett Cope and CFO Michael Metcalf on January 2, 2026, and the board approved them on January 3, 2026. The awards raise each executive's annual long-term incentive target and set it as a fixed dollar amount rather than a multiple of base salary. The change increases potential equity pay tied to performance goals, and shareholders will see it reflected in future compensation costs.
Cope's target value is $2,200,000, up from 170% of base salary, which is currently $750,000.
Metcalf's target value is $600,000, up from 75% of base salary, which is currently $424,400.
Cope's award is now 60% performance-based and 40% time-based, versus a 50/50 split previously.
Performance units add a three-year Revenue Compound Annual Growth Rate goal alongside EBITDA and safety goals.
