O'Neil Christian G. 4

What Happened

• Christian G. O'Neil, President and COO of Kirby Corp (KEX), had restricted stock units (RSUs) convert into 10,188 shares on Feb 3, 2026 (reported Feb 5, 2026). To cover tax withholding, 4,011 shares were surrendered/sold at $120.68 per share, generating $484,047. The remaining 6,177 shares (10,188 − 4,011) were retained by O'Neil from this vesting event.
• Transaction codes: M = exercise/conversion of derivatives (the RSU conversion); F = payment of tax liability via share withholding/sale.

Context

• This is a routine vesting and tax-withholding event (RSUs converting to shares and a “sell-to-cover” or share surrender to satisfy tax obligations), not an open-market investment decision. Such withholding is common and should not be read as a standalone bullish or bearish signal.
• For retail investors: purchases or open-market buys by insiders often carry more direct informational weight than routine vesting/tax-withholding transactions.
