O'Neil Christian G. 4

What Happened

• Christian G. O'Neil, President and COO of Kirby Corp (KEX), had 2,660 restricted stock units (RSUs) vest/convert on Jan 24, 2026 (reported on Form 4 filed Jan 27, 2026). The RSUs converted at an exercise/conversion price of $0.00.
• To cover tax withholding, 1,098 of those shares were surrendered/withheld at $128.70 per share, totaling $141,313 (transaction code F). The net result is retention of 1,562 shares (2,660 converted minus 1,098 withheld), worth roughly $201,000 at $128.70/share.
• The filing shows a derivative settlement entry (transaction code M) for the conversion/settlement of the RSUs and the withholding disposition; this is a routine vesting/net settlement rather than an open-market purchase or sale.
