Colwell Michael C. 4

What Happened Michael C. Colwell, Senior Vice President of Kadant Inc. (KAI), had a series of restricted stock unit (RSU) awards partly vest and convert to common stock on March 10, 2026. A total of 1,632 shares were issued on a one-for-one conversion of RSU-like derivatives, and 743 of those shares were withheld (disposed) to satisfy tax withholding obligations, resulting in approximately $248,288 paid for taxes. Net new shares delivered to Colwell after withholding were 889 shares.

Key Details

• Transaction date: March 10, 2026; Form 4 filed March 12, 2026 (timely).
• What converted: Six partial settlements (performance- and time-based RSU awards granted in 2023, 2024 and 2025) — one‑third of each award vested and converted to common stock on vesting date (see footnotes F1–F6).
• Shares converted/acquired: 1,632 common shares (conversion of derivatives / RSUs).
• Shares withheld/disposed for taxes (code F): 743 shares at $334.17 per share = $248,288 total withheld.
• Net shares delivered to insider: 889 shares (1,632 issued − 743 withheld).
• Filing timeliness: Report appears timely (filed two days after the transactions).
• Note on codes: M = conversion/exercise of derivative (RSU conversion here); F = payment of tax liability via share withholding (not an open-market sale).

Context This was not an open-market sale or purchase but the routine vesting and conversion of RSU awards, with shares withheld to cover tax obligations. Such transactions reflect compensation being settled rather than insider leaning bullish or bearish; the material action for investors is the net issuance of 889 shares to the insider after withholding.
