MIONIS ROBERT 4

What Happened

• Robert Mionis, CEO of Celestica (CLS), had 12,133 restricted share units (RSUs) convert into common shares on Feb 4, 2026. Of those, 4,775 shares were withheld/sold to satisfy tax withholding at $297.45 per share, generating $1,420,324. Net shares delivered to Mionis after withholding: 7,358.
• The Form 4 shows the RSU-to-share conversion (transaction code M) and the withholding/sale to cover taxes (transaction code F). This is a routine vesting/tax-withholding event rather than an open-market purchase or intentional sale signal.

Context

• This was a conversion/vesting event of RSUs with a routine tax-withholding sale — common for equity-compensation settlements and not necessarily a sign of confidence or concern by the insider. Because the RSUs had no exercise price, the conversion is recorded as a derivative conversion (M) and the withholding is recorded separately (F).
• Purchases tend to be a stronger bullish signal for investors; tax-related withholdings are administrative.
