MITTELSTAEDT RONALD J 4

What Happened
Ronald J. Mittelstaedt, President & CEO and a director of Waste Connections, had 878 restricted share units convert into common shares on February 18, 2026 (reported on a Form 4 filed Feb 20, 2026). Of those 878 shares, 346 were withheld by the issuer to satisfy applicable taxes at $162.76 per share, totaling $56,315. The conversion is a vesting event (not an open-market buy or sell).

Key Details

• Transaction date: February 18, 2026; Form 4 filed February 20, 2026 (timely filing).
• Conversion (code M): 878 shares issued upon RSU vesting at $0 exercise price.
• Tax withholding (code F): 346 shares withheld/disposed at $162.76 per share = $56,315.
• Footnote F1: Withheld shares satisfy applicable withholding taxes.
• Footnote F2: These RSUs were awarded Feb 18, 2022 and vest in four equal annual installments; this report covers the conversion of that installment.
• Shares owned after the transaction: not specified in the provided filing excerpt.

Context
This was a routine vesting/conversion of RSUs into common stock followed by withholding to cover taxes (a cashless-like settlement for tax purposes). Such transactions reflect compensation vesting rather than a manager buying or selling stock for investment reasons.
