What Happened

Amy D. Husted, Executive Vice President, General Counsel & Secretary of Kirby Corporation (KEX), reported multiple derivative conversions (vestings) on Feb 3, 2026. The filing shows an acquisition of 7,319 shares (conversion of derivative securities) at $0.00 and several other conversions reported as disposals (2,273; 2,219; 1,911; 916 shares at $0.00).
The filing also reports a tax-withholding disposal of 2,882 shares sold at $120.68 per share, totaling $347,800. Transaction codes: M = exercise/conversion of derivative; F = payment of exercise price or tax liability (share surrender for taxes).

Key Details

Transaction date: February 3, 2026; Form 4 filed February 5, 2026 (appears timely).
Reported lines: Acquired 7,319 shares (M, $0.00); Disposed for tax withholding 2,882 shares at $120.68 each = $347,800 (F); Additional derivative disposals: 2,273; 2,219; 1,911; 916 shares (M, $0.00).
Shares owned after the transactions: not specified in the provided filing excerpt.
Footnotes: These transactions involve restricted stock units (RSUs). Each RSU is a contingent right to receive cash or one share; grants from 2022–2025 vest in five equal annual installments beginning on Feb 3 of successive years. The issuer may elect to deliver cash or shares on vesting.

Context

These entries reflect RSU vesting/settlement activity and a routine tax-withholding share surrender (F), not an open-market sale decision by the insider. When RSUs are settled, companies often withhold shares to cover taxes; that appears to be the case here.
For retail investors: this is insider compensation settlement activity rather than a discretionary purchase or sale indicating bullish/bearish trading intent.
