Woodruff William Matthew 4

What Happened
William Matthew Woodruff, VP of Public and Government Affairs at Kirby Corporation (KEX), had restricted stock units (RSUs) vest on February 3, 2026. A total of 1,109 shares were converted from RSUs into common stock (recorded as derivative conversions). To satisfy tax withholding, 475 shares were withheld and disposed at $120.68 per share, generating $57,323. The net shares delivered to Woodruff were 634 (1,109 vested − 475 withheld). The RSU conversions are non‑purchase compensation events, not an open‑market buy.

Context
This filing reflects standard RSU vesting and net share withholding to cover taxes (a common payroll tax withholding treatment). Such award settlements are compensation events and generally do not by themselves indicate the insider’s market view.
