DIRTT ENVIRONMENTAL SOLUTIONS LTD

Our principal executive offices are located in Calgary, Alberta, where we lease approximately 73,000 square feet of office and manufacturing space. Our lease expires in September 2030. Our principal manufacturing facilities are currently located in Calgary, Alberta; and Savannah, Georgia. On February 22, 2022, we announced our intention to close the Phoenix manufacturing facility and DXC. On September 27, 2023, we announced our intention to permanently close the Rock Hill Facility.

Our wall surfaces (which we call panels), casework and timber solutions are manufactured in Calgary, while aluminum, glass and power components are manufactured in Calgary and Savannah. In Calgary, we lease an aggregate of approximately 400,000 square feet of manufacturing space across four facilities (excluding our principal offices), which leases expire in January 2026, January 2030, September 2027, and January 2034. In Savannah, we lease approximately 81,000 square feet of manufacturing space, which lease expires in February 2029. In Phoenix, we lease approximately 130,000 square feet of manufacturing space across two facilities, which leases expire in March 2027. As at December 31, 2024, all of our Phoenix space is subleased for the remainder of our lease. In October 2019, we entered into a fifteen-year lease, which DIRTT may extend for two additional five-year periods at its option, for a panel factory of approximately 130,000 square feet in Rock Hill, South Carolina. Should the need arise, we have the expansion rights to lease an additional 130,000 square feet of space. We are pursuing options to sublease this area following the September 27, 2023 announcement of our intention to permanently close operations at this location and do not plan to exercise the additional five-year extension period. In March 2020, we entered into an eight-year lease, which DIRTT may extend an additional five years at its option, of approximately 18,000 square feet of space for a DXC in Plano, Texas. During March 2023, we entered into an agreement to sublease our DXC in Plano to one of our Construction Partners in that region, from April 1, 2023, through October 31, 2028.

In Chicago, Illinois, we own approximately 6,200 square feet of office space, which we use to operate a DXC.

Through distributed manufacturing, we can shift production of some components among our manufacturing sites, reduce transportation times and costs, and meet targeted lead times. We believe that our current and planned facilities are adequate for our current needs and that suitable additional or substitute space would be available if needed.
