1. F1. 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. F2. The price used to calculate the number of DSUs granted was C$0.71, which was the closing price Issuer's Common Shares as reported on the Toronto Stock Exchange on June 29, 2026. The price was converted using the Bank of Canada exchange rate for June 29, 2026 of C$1.4206 = US$1.00.

Deferred Share Unit financial

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.

US Directors 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."

Toronto Stock Exchange financial

"The price used to calculate the number of DSUs granted was C$0.71, which was the closing price Issuer's Common Shares as reported on the Toronto Stock Exchange"

The Toronto Stock Exchange is Canada’s largest organized marketplace where shares of publicly traded companies are bought and sold, similar to a large, regulated marketplace for company ownership. It matters to investors because it provides transparent prices, rules that help protect buyers and sellers, and access to many Canadian and international businesses, so movements there can signal economic trends and affect portfolio values.
