Insights

Corporate Governance Specialist

Grant reflects routine director compensation aligned with long‑term equity incentives.

The 34,308 DSUs are granted under the issuer's established long‑term incentive plan and vest as an economic entitlement payable at termination of service, which is a common mechanism to align director interests with shareholders without immediate dilution.

This grant is disclosed under Section 16 reporting rules and appears to be a routine, non‑exercisable deferred award rather than an option or convertible security, indicating limited immediate market impact.

Executive Compensation Analyst

DSU calculation uses specific market and FX inputs disclosed, clarifying value.

The DSU count was based on a Toronto Stock Exchange closing price of C$0.80 and the Bank of Canada exchange rate of C$1.3941 = US$1.00, yielding a US dollar equivalent price shown as $0.57. This transparent methodology allows investors to approximate the grant's dollar value.

The award settles in shares or cash after separation; because settlement timing depends on termination, the immediate dilution effect is delayed until the DSUs convert to shares.

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.
