Endo reports its results on a calendar year basis. The income statement information for the respective periods are combined within the Pro Forma Financial Information above, given the difference in the fiscal period end of Mallinckrodt and Endo. 2 The supplemental financial information contains Adjusted EBITDA, which is considered a “Non-GAAP” financial measure under the applicable U.S. Securities and Exchange Commission’s rules and regulations, together with the reconciliation to the most directly comparable GAAP financial measure. Management strongly encourages readers to review Mallinckrodt's and Endo's audited and unaudited condensed consolidated financial statements and publicly filed reports in their entirety. 3 Endo, Inc.'s four historical reportable business segments are Branded Pharmaceuticals, Sterile Injectables, Generic Pharmaceuticals and International Pharmaceuticals. Within this exhibit, references to "GxSI Combined" represent the combined activity for Endo, Inc.'s Sterile Injectables and Generic Pharmaceuticals segments. There are no intersegment transactions requiring elimination. 4 Pro Forma Adjusted EBITDA includes approximately $35 million and approximately $9 million of annual and quarterly dissynergies, respectively, as well as certain adjustments to legal expenses in the historical periods presented. 5 As disclosed in Mallinckrodt's quarterly report on Form 10-Q for the three months ended March 28, 2025 (Successor), management measures and evaluates Mallinckrodt's operating segments based on segment net sales and operating income. Certain amounts that management considers to be non-recurring or non-operational are excluded from segment operating income because the chief operating decision maker evaluates the operating results of the segments excluding such items. These items may include, but are not limited to corporate and unallocated expenses, combination, integration, and other related costs, and liabilities management and separation costs. Although these amounts are excluded from segment operating income, as applicable, they are included in reported consolidated operating loss and are reflected in the reconciliations presented above. Management believes that the segment operating income is the most directly comparable U.S. GAAP measure for the segment Adjusted EBITDA. 6 Represents the allocation of additional operating costs attributable to the Specialty Generics business in each period. 7 Represents capital expenditures and working capital amounts attributable to the Specialty Generics business in each period derived from consolidated amounts. 8 As disclosed in Endo’s quarterly report on Form 10-Q for the three months ended March 31, 2025 (Successor), management measures and evaluates Endo's operating segments based on segment adjusted income (loss) from operations before income tax. Certain amounts that management considers to be non-recurring or non-operational are excluded from segment adjusted income (loss) from operations before income tax because the chief operating decision maker evaluates the operating results of the segments excluding such items. These items may include, but are not limited to acquired in-process research and development charges; acquisition-related and integration items, including transaction costs and changes in the fair value of contingent consideration; cost reduction and integration-related initiatives such as separation benefits, continuity payments, other exit costs and certain costs associated with integrating an acquired company’s operations; certain amounts related to strategic review initiatives; asset impairment charges; amortization of intangible assets; inventory step-up recorded as part of our acquisitions; litigation-related and other contingent matters; certain legal costs; gains or losses from early termination of debt; debt modification costs; gains or losses from the sales of businesses and other assets; foreign currency gains or losses on intercompany financing arrangements; reorganization items, net (in the Predecessor periods); and certain other items. Although these amounts are excluded from segment adjusted income (loss) from operations before income tax, as applicable, they are included in reported consolidated operating loss and are reflected in the reconciliations presented above. Management believes that the segment operating income is the most directly comparable U.S. GAAP measure for the segment Adjusted EBITDA. 9 As required by GAAP, due to the application of Fresh Start Accounting by both Mallinckrodt and Endo, activity for must be presented separately for the predecessor period prior to the application of Fresh Start Accounting (the “Predecessor” period) and the successor period following the application of Fresh Start Accounting (the “Successor” period). However, to facilitate the accumulation of the reconciliation above, results for Predecessor and Successor periods have been combined and reflected as non-GAAP measures (“combined” results).
