Niemietz Kurt A. 4

What Happened

• Kurt A. Niemietz, VP of Investor Relations & Treasurer at Kirby Corp (KEX), had 493 restricted stock units (RSUs) vest/convert into common shares on January 24, 2026. The conversion shows an exercise/conversion price of $0.00 (no cash exercise).
• Of the 493 shares, 220 were surrendered/withheld to cover tax withholding at a value of $128.70 per share, totaling $28,314. The net shares delivered to Niemietz were 273 (493 − 220). There was no open-market sale noted—the only disposition was tax withholding.

Key Details

• Transaction date: 2026-01-24; Form 4 filed: 2026-01-27.
• Conversion/vesting: 493 RSUs → 493 shares (derivative conversion; transaction code M).
• Tax withholding: 220 shares withheld (transaction code F) at $128.70/share = $28,314.
• Net shares received: 273 shares.
• Shares owned after transaction: not specified in the filing.
• Footnotes: F1 explains each RSU can be settled in cash or one share; F2 notes these RSUs were granted Jan 29, 2021 and vest in five equal annual installments beginning Jan 24, 2022. The issuer appears to have elected to settle in shares and withheld shares for taxes.

Context

• This was a routine vesting/settlement of RSUs with net-share tax withholding (a common way companies satisfy tax obligations). It is not an open-market purchase or sale by the insider and does not necessarily indicate a change in insider sentiment.
