Kirby (KEX) CFO Kumar Raj Exercises RSUs, Sells Shares for Taxes

What Happened

Kumar Raj, Executive Vice President and Chief Financial Officer of Kirby Corporation (KEX), had restricted stock units (RSUs) convert/vest on Feb 3, 2026. The Form 4 shows a total of 10,916 RSU-related conversions/exercises.
Of those, 2,208 shares were withheld/sold to cover tax withholding at $120.68 per share, generating proceeds of $266,461 (transaction code F). The remainder of the vested RSUs were converted into shares and retained (net increase of 8,708 shares based on the filing lines).

Key Details

Transaction date: February 3, 2026; Form 4 filed February 5, 2026 (filed within the typical two-business-day window).
Tax-withholding sale: 2,208 shares @ $120.68 for $266,461 (code F).
RSU conversions/exercises listed (code M) total 10,916 shares across multiple grant vintages.
Footnotes: Each RSU represents a contingent right to cash or one share. Grants referenced were made in 2022, 2023, 2024 and 2025 and vest in five equal annual installments (see F1–F5); the issuer may deliver cash or shares at its election on vesting.
Shares owned after the transaction: not specified in the excerpted filing.

Context

This was a routine vesting and tax-withholding event (not an open-market purchase or a discretionary sale). Withholding/sale to cover taxes (code F) is common on RSU vesting and is not necessarily a signal about the insider’s view of the stock.
Because multiple RSU grants and vesting schedules are noted, the filing reflects scheduled compensation vesting rather than a new option grant or a 10% beneficial-owner transaction.
