IMAX CEO Daniel Manwaring Exercises RSUs; Shares Withheld for Taxes

What Happened

Daniel Manwaring (CEO, IMAX China Holding, Inc.) converted vested restricted share units (RSUs) into common IMAX shares on March 7, 2026. He had conversions of 7,409 and 4,666 RSUs (reported as derivative exercises at $0), and received a grant/award of 5,072 RSUs. To satisfy tax withholding related to the RSU delivery, IMAX withheld 5,435 shares and recorded a disposition of those shares at $40.80 each, totaling $221,748.
These transactions are conversions/settlements of equity awards (not open-market purchases or voluntary sales); the withholding of shares to pay taxes is a routine administrative disposition.

Context

These were RSU conversions and a company share-withholding to cover taxes — a common, administrative outcome when restricted units vest. This is not an open-market sale by the insider for investment purposes, though it is a disposition of shares to satisfy tax liability.
