Westerhout Fredrik H 4

What Happened

• Fredrik H. Westerhout, Vice President of Kadant Inc. (KAI), had portions of multiple RSU awards vest on March 10, 2026. A total of 1,629 shares were converted from outstanding RSU/derivative awards (exercise/conversion, code M). To satisfy tax withholding obligations, 808 of those shares were withheld/settled (code F) at a withholding price of $334.17 per share, generating roughly $270,009 in tax payments. The net result was an increase of 821 shares to his beneficial ownership.

Key Details

• Transaction date: March 10, 2026; Form 4 filed March 12, 2026 (filed within the typical 2-business-day window).
• Shares converted/issued: 1,629 total (from multiple RSU awards).
• Shares withheld/settled for taxes: 808 shares at $334.17 each = ~$270,009.
• Net shares retained: 821 shares added to holdings (1,629 issued − 808 withheld).
• Footnotes: The shares come from partial settlements (one‑third vesting) of performance- and time-based RSU awards granted March 7, 2023; March 6, 2024; and March 4, 2025, each converted one-for-one into common stock on vesting (see F1–F6).
• Transaction codes: M = exercise/conversion of derivative (RSU conversion); F = payment of exercise price or tax liability (share withholding).

Context

• This is a routine RSU vesting and tax-withholding transaction (common for employees/executives) rather than an open-market buy or discretionary sale. The conversion of RSUs and withholding of a portion of shares to cover taxes is effectively a cashless settlement and does not, by itself, signal a change in sentiment.
