DIRTT ENVIRONMENTAL SOLUTIONS LTD

There have been no material developments in the legal proceedings previously disclosed in our Annual Report on Form 10-K for the year ended December 31, 2024 except as described below regarding DIRTT’s litigation against Falkbuilt, Messrs. Smed and Loberg, and their associates.

With respect to the DIRTT’s lawsuit against Falkbuilt in Utah, on February 5, 2025, the U.S. District Court for the Northern District of Utah (the “Utah Court”) granted Falkbuilt’s motion to dismiss the case, on the basis of forum non conveniens. In simple terms, the Utah Court decided that it would not hear DIRTT’s claim in Utah because Canada was more appropriate, and Canadian law applies to most of DIRTT’s claims. Further the Utah Court found that DIRTT’s Canadian company, DIRTT Environmental Solutions Ltd., owns the trade secrets that were the subject matter of the Utah claim, so whether the theft of those trade secrets occurred in Canada or abroad, they would result in injury to DIRTT Environmental Solutions Ltd. and should be pursued in Canada. The Utah Court, in essence, redirected the determination of those damages from Utah to Canada, being the appropriate forum for the legal dispute. On March 4, 2025, DIRTT filed a motion for reconsideration pursuant to Federal Rules of Civil Procedure, Rule 60(b). The reconsideration requests relief from the Utah Court’s February 5, 2025, Memorandum Decision and Order granting the Defendant’s motion to dismiss for forum non conveniens. The briefing is complete as of April 15, 2025, and the parties are awaiting a decision.

In November 2024, the Alberta Court of King’s Bench scheduled an 8-week trial commencing February 2, 2026, and running until March 27, 2026 for DIRTT’s action against Falkbuilt, Messrs. Smed and Loberg and several other former DIRTT employees alleging breaches of restrictive covenants, fiduciary duties, employment duties and confidentiality. DIRTT is pursuing damages and losses it suffered in Canada, the United States, and abroad in the Court of King’s Bench of Alberta. The Court of King’s Bench will determine whether Falkbuilt, Messrs. Smed and Loberg and others wrongfully caused DIRTT to suffer damages, which could exceed $50,000,000.
