(a) Restructuring charges: Our restructuring activities consisted primarily of actions to adjust our cost base to address reduced levels of demand in certain of our businesses and geographies. In Q3 2025, YTD 2025 and the respective prior year periods, our restructuring charges consisted primarily of cash charges related to employee terminations and accelerated depreciation of equipment related to disengaging programs. At September 30, 2025, our restructuring provision was $4.4 (December 31, 2024 — $2.9), which we recorded in accrued and other current liabilities and provisions on our consolidated balance sheet. (b) Transition Costs: See note 14 to the 2024 AFS for a description of costs recorded as Transition Costs. In March 2019, as part of our Toronto real property sale, we entered into a 10-year lease with the purchaser of such property for our then-anticipated headquarters, to be built by such purchaser on the site of our former location (Purchaser Lease). Due to a number of construction-related commencement date delays, in November 2022, we extended (on a long-term basis) the lease on our current corporate headquarters, and in the third quarter of 2023 and the second quarter of 2025, we executed sublease agreements for the leased space under the Purchaser Lease. The Purchaser Lease commenced in June 2024 and related ROU assets and lease liabilities were recognized in our consolidated financial statements. We recorded charges related to the sublet of the Purchaser Lease as Transition Costs (nil in Q3 2025 and $0.4 in YTD 2025; nil in Q3 2024 and $4.8 in YTD 2024). (c) Other charges (recoveries): In Q3 2025 and YTD 2025, we recorded other charges of nil and $1.4, respectively, related to our transition as a U.S. domestic filer. Oth er recoveries of $1.3 in YTD 2024 consisted of legal recoveries in connection with the settlement of class action lawsuits (for component parts purchased in prior periods) in which we were a plaintiff.
