Non-GAAP Financial Measures Our non-GAAP financial measures, such as non-GAAP earnings and related EPS information, are adjusted to exclude certain costs, expenses, gains and losses and other specified items that are evaluated on an individual basis. These items are adjusted after considering their quantitative and qualitative aspects and typically have one or more of the following characteristics, such as being highly variable, difficult to project, unusual in nature, significant to the results of a particular period or not indicative of future operating results. Similar charges or gains were recognized in prior periods and will likely reoccur in future periods including (i) amortization of acquired intangible assets beginning in the fourth quarter of 2019, including product rights that generate a significant portion of our ongoing revenue and will recur until the intangible assets are fully amortized, (ii) unwind of inventory fair value adjustments, (iii) acquisition and integration expenses, (iv) restructuring costs, (v) accelerated depreciation and impairment of property, plant and equipment and intangible assets, (vi) R&D charges or other income resulting from upfront or contingent milestone payments in connection with the acquisition or licensing of third-party intellectual property rights, (vii) costs of acquiring a priority review voucher, (viii) IPRD charge resulting from the MyoKardia acquisition, (ix) divestiture gains or losses, (x) stock compensation resulting from accelerated vesting of Celgene awards and certain retention-related employee compensation charges related to the Celgene transaction, (xi) pension, legal and other contractual settlement charges, (xii) interest expense on the notes issued in May 2019 incurred prior to our Celgene transaction and interest income earned on the net proceeds of those notes, (xiii) equity investment and contingent value rights fair value adjustments and (xiv) amortization of fair value adjustments of debt acquired from Celgene in our 2019 exchange offer, among other items. Deferred and current income taxes attributed to these items are also adjusted for considering their individual impact to the overall tax expense, deductibility and jurisdictional tax rates. Certain other significant tax items are also excluded such as the impact resulting from internal transfer of intangible assets and the  Otezla * divestiture. We also provide international revenues for our priority products excluding the impact of foreign exchange. Reconciliations of these non-GAAP measures to the most comparable GAAP measures are included in Exhibit 99.2 to our Form 8-K filed on February 4, 2021 and are incorporated herein by reference. Non-GAAP information is intended to portray the results of our baseline performance, supplement or enhance management, analysts and investors’ overall understanding of our underlying financial performance and facilitate comparisons among current, past and future periods. For example, non- GAAP earnings and EPS information is an indication of our baseline performance before items that are considered by us to not be reflective of our ongoing results. In addition, this information is among the primary indicators that we use as a basis for evaluating performance, allocating resources, setting incentive compensation targets and planning and forecasting for future periods. This information is not intended to be considered in isolation or as a substitute for net earnings or diluted EPS prepared in accordance with GAAP and may not be the same as or comparable to similarly titled measures presented by other companies due to possible differences in method and in the items being adjusted. We encourage investors to review our financial statements and publicly-filed reports in their entirety and not to rely on any single financial measure. 53
