Revenue fell 5.8% year over year. Adjusted EBITDA declined 8.5%. a combination of timing of project execution, a more normalized level of GLP-1-related activities compared to the prior-year period, and the impacts of the restructuring activities within the Company's transportation businesses.

The reported figure also came in approximately C$6.3 million below the low end of the C$700 million to C$740 million range Interim CFO Michael Anne Cybulski provided on the Q4 fiscal 2026 earnings call held May 28, 2026. Alongside the results, management announced an 18-month fixed-cost transformation program.
