DIRTT Environmental Solutions (DRTTF) discloses director award of 28,527 DSUs

Rhea-AI Filing Summary

DIRTT Environmental Solutions Ltd. director filed a Form 4 reporting an award of deferred share units rather than a stock trade. On 12/31/2025, the director received 28,527 deferred share units (DSUs) under the company’s Third Amended and Restated Long Term Incentive Plan. Each DSU is the economic equivalent of one common share and is linked to the value of DIRTT’s common shares.

For U.S. directors, settlement must occur no later than 40 days after the termination date, in either common shares or cash based on the share price. The grant was calculated using a reference price of C$0.90 per common share, the Toronto Stock Exchange closing price on December 30, 2025, converted at a Bank of Canada rate of C$1.3693 = US$1.00, corresponding to an approximate U.S. dollar price of $0.66 per unit.
