| Schedule of Disaggregation of Revenue |
We disaggregate revenue from contracts with customers by major product line and based on the timing of recognition for each of our reportable segments, as we believe such disaggregation best depicts how the nature, amount, timing, and uncertainty of our revenues and cash flows are affected by economic factors, with such disaggregation presented below for the three and six months ended June 27, 2026 and June 28, 2025: | | | | | | | | | | | | | | | | | | | | | | | Three months ended June 27, 2026 | | Reportable Segments | | HVAC | | Detection and Measurement | | Total | | | | | | | | | Major product lines | | | | | | | | Package and process cooling equipment and services, and engineered air movement and handling solutions | | $ | 319.0 | | | $ | — | | | $ | 319.0 | | | Hydronic heating, electrical heating, and ventilation | | 161.6 | | | — | | | 161.6 | | Underground locators, inspection and rehabilitation
