Insights

Compensation Analyst

Director received 45,276 DSUs, aligning pay with equity performance.

The grant of 45,276 DSUs ties the director's future payout to the company's share price because each DSU converts to one common share or cash based on market price at settlement.

The grant price used was C$0.80 (converted to $0.57), which is the valuation basis for the award and affects the number of units issued.

Corporate Governance Analyst

DSUs vest at termination and settle up to 40 days for U.S. directors.

The DSUs do not settle immediately; they convert only after the director's Termination Date, which preserves long-term alignment and retention incentives.

The filing reports 867,575 shares beneficially owned after the grant, a concrete disclosure of post-transaction ownership that investors can use to assess insider alignment.

Explanation of Responses:

1. Each deferred share unit ("DSU") was granted pursuant to the DIRTT Environmental Solutions Ltd. Third Amended and Restated Long Term Incentive Plan and is the economic equivalent of one common share (a "Common Share") of DIRTT Environmental Solutions Ltd. (the "Issuer"). All DSUs settle following the cessation of service and employment with the Issuer (the "Termination Date"). For directors who are subject to taxation in the United States ("US Directors"), the DSUs will settle no later than forty days following the Termination Date. Each DSU will be settled in one Common Share or in the cash equivalent of such Common Shares, calculated based on the closing price of the Common Shares on the day prior to the 30th day following separation from service for US Directors.

2. The price used to calculate the number of DSUs granted was C$0.80, which was the closing price Issuer's Common Shares as reported on the Toronto Stock Exchange on September 26, 2025. The price was converted using the Bank of Canada exchange rate for September 26, 2025 of C$1.3941 = US$1.00.
