LANIGAN MATTHEW 4

What Happened
Matthew Lanigan, President & CEO and a director of NPK International Inc. (NPKI), received a grant of 85,771 restricted stock units (RSUs) on 2026-05-19. The award shows an acquisition price of $0.00 (no cash paid on grant) and will settle in company shares when the RSUs vest. This is a compensatory award rather than an open‑market purchase or sale.

Context
RSU grants are common executive compensation and do not by themselves indicate buying or selling sentiment; they represent future share delivery contingent on vesting. Because these RSUs settle in shares over time, they will become taxable and convert into common stock as each vesting tranche is delivered.
