Definitions of Non-GAAP Reconciliation items The following items have been excluded in our non-GAAP financial measures: Intangible amortization: Includes amortization of intangible assets established during purchase accounting for business combinations. These amounts are highly dependent on the size and frequency of acquisitions and are being excluded to allow for a more consistent comparison with forecasted, current and historical results and the results of our peers. Goodwill and intangible asset impairment charges: These charges were incurred as a result of a decline in market capitalization of the company and lower than projected financial results of certain reporting units due to customer losses and operational inefficiencies. Fair value adjustments related to purchase accounting: Includes an incremental charge to cost of goods sold from purchase accounting impacts related to the sale of acquired inventory that was written up to fair value in connection with the Halyard acquisition. Acquisition-related and exit and realignment charges: Acquisition-related charges consist primarily of transition costs for the Halyard and Byram acquisitions, as well costs associated with the Apria acquisition. Exit and realignment charges consist primarily of an increase in reserves associated with certain retained assets of Fusion5, wind-down costs related to Fusion5, IT restructuring charges, post closing costs associated with the Movianto divestiture, and other costs related to the reorganization of the U.S. commercial, operations and executive teams. Loss on extinguishment and modification of debt: Includes the write-off of deferred financing costs and third-party fees and amounts reclassified from accumulated other comprehensive loss as a result of the termination of our interest rate swaps. Software as a service implementation costs: These charges are associated with significant global IT platforms in connection with the redesign of our global information system strategy. Other expense (income), net: Includes interest costs and net actuarial losses related to our retirement plans. Tax Adjustments: Includes a tax adjustment associated with the estimated benefits under the Tax Cuts and Jobs Act and the Coronavirus Aid, Relief, and Economic Security (CARES) Act. Other depreciation and amortization: Includes depreciation expense for property and equipment and amortization for capitalized computer software. Apria adjusted EBITDA: Is presented in order to calculate pro forma adjusted EBITDA and pro forma leverage ratio of net debt to adjusted EBITDA for the twelve months ended March 31, 2022 as if Apria was acquired on April 1, 2021. The pro forma results are not necessarily indicative of the results that would have been if the acquisition had occurred on April 1, 2021. We have not separately presented the components of Apria adjusted EBITDA, as we determined that such presentation would not be meaningful. 21 Owens VI & Minor
