Deferred Share Unit financial

"Each deferred share unit ("DSU") was granted pursuant to the DIRTT Environmental Solutions Ltd. Third Amended and Restated Long Term Incentive Plan"

Third Amended and Restated Long Term Incentive Plan financial

"Each deferred share unit ("DSU") was granted pursuant to the DIRTT Environmental Solutions Ltd. Third Amended and Restated Long Term Incentive Plan"

Termination Date financial

"All DSUs settle following the cessation of service and employment with the Issuer (the "Termination Date")."

Termination date is the specific calendar day when a contract, agreement, option or other legal arrangement stops being in effect and any remaining rights or obligations expire. For investors it matters because that date sets deadlines for exercising rights, receiving payments, closing positions or avoiding penalties—similar to the day a lease or warranty ends, after which parties no longer have the same protections or claims.

Bank of Canada exchange rate financial

"The price was converted using the Bank of Canada exchange rate for June 29, 2026 of C$1.4206 = US$1.00."

Deferred Share Units (DSUs) financial

"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."

Deferred share units (DSUs) are a form of long-term compensation that give an executive or director a payable claim whose value moves with the company’s stock price but is not paid out until a later date, often when they leave the company. Think of a DSU as an IOU tied to the share price that becomes cash or shares in the future; investors watch DSUs because they affect potential share dilution, the timing of cash outflows, and whether management’s interests align with long-term shareholder value.
