MacMillan Michael 4

What Happened

• Michael MacMillan, a director of IMAX Corporation (IMAX), was granted restricted share units (RSUs) that vested and converted into 3,390 common shares on June 11, 2026. The RSUs convert at no exercise price.
• To satisfy tax withholding obligations, 1,849 of those shares were withheld/disposed at an implied value of $42.12 per share, totaling $77,880. Net shares delivered to Mr. MacMillan were 1,541 common shares (3,390 vested − 1,849 withheld).
• This is an award/vesting event (not an open-market buy or a voluntary sale); withholding of shares for taxes is a routine administrative step.

Context

• RSU vesting and withholding are routine compensation events for directors and do not necessarily indicate a buy/sell signal. The conversion was effectively a cashless settlement for taxes (shares withheld rather than a cash payment).
