Insights

Routine PSU vesting with tax withholding; no open‑market trading signal.

Lauren McNamara, an officer of SunOpta Inc., exercised 13,905 Performance Stock Units into common shares. The exercise price was reported as $0.00, consistent with stock-based compensation where employees receive shares upon vesting rather than paying cash.

The company then withheld 6,453 shares at $4.12 per share to satisfy income tax obligations, a standard mechanism classified with code F. This disposition is not an open-market sale and does not reflect an active decision to sell shares.

Following these actions, McNamara held 121,880 common shares directly, and no derivative awards remained in the filing’s derivative summary, indicating the reported PSUs were fully settled. The filing also clarifies that this total includes 1,318 shares previously purchased via the employee stock purchase plan and not earlier reported.
