The Peer Group TSR set forth in this table utilizes the Dow Jones U.S. Select Pharmaceuticals Index, which we also utilize in the stock performance graph required by Item 201(e) of Regulation S-K, included in our Annual Report for the year ended December 31, 2022. The comparison assumes $100 was invested for the period starting December 31, 2019 (The last trading day of fiscal 2019), through the end of the listed year in the Company and in the Dow Jones U.S. Select Pharmaceuticals Index, respectively. Historical stock performance is not necessarily indicative of future stock performance.

We determined Adjusted EBITDA to be the most important financial performance measure used to link Company performance to Compensation Actually Paid to our PEOs and Non-PEO NEOs in 2022. This performance measure may not have been the most important financial performance measure for years 2021 and 2020, and we may determine a different financial performance measure to be the most important financial performance measure in future years. Adjusted EBITDA is not a term defined under U.S. GAAP. We define adjusted EBITDA as net income before net interest expense, income taxes, and depreciation and amortization (“EBITDA”), as adjusted for certain other items described in our SEC filings, including stock-based compensation expense, acquisition, site closure and idle facility expenses, restructuring and other charges, net charges related to legal matters, asset impairment charges, foreign exchange losses or gains, change in fair value of contingent consideration, and insurance recoveries for property losses and associated expenses. Prior to January 1, 2022, research and development milestone expenses related to license and collaboration agreements were excluded from our calculation of adjusted EBITDA. The amounts shown in this column for the fiscal years ended December 31, 2021 and December 31, 2020 reflect this historical
