KEY DEFINITIONS AND NOTES Except as otherwise noted all references to 2024 and 2023 represent our results for the period indicated, presented on an adjusted basis. “Organic Sales" refers to GAAP revenue excluding (1) the impact of currency translation and (2) the impact of revenue from acquired businesses recorded prior to the first anniversary of the acquisition less the amount of sales attributable to divested product lines not considered discontinued operations. Reportable segment income (“segment income”) represents operating income of each reportable segment exclusive of intangible amortization, acquisition related costs, costs of restructuring activities, impairments and other unusual non-operating items. Adjusted operating income represents consolidated operating income exclusive of intangible amortization, acquisition related expenses, costs of restructuring activities, impairments and other unusual non-operating items. CONTINUING OPERATIONS As a result of the previously announced agreement to sell the Thermal Management business, we are reporting the results of that business as discontinued operations and have reclassified 2023 and 2024 results for all prior periods on a continuing operations basis. All results referenced throughout this presentation are on a continuing operations basis unless otherwise stated. Forward-Looking Statements
