​ (1) Mr. Lipps served as the Company’s principal executive officer for the entirety of 2020, 2021, 2022, 2023, and 2024 and the Company’s other NEOs for the applicable years were as follows: ​ 2024: Nnamdi Njoku, Nchacha E. Etta, and Corey J. Manley 2023: Nchacha E. Etta; Corey J. Manley; Peter J. Kuipers; Scott P. Seidelmann; and Christine Mellon. 2022: Peter J. Kuipers; Scott P. Seidelmann; Christine Mellon, Corey J. Manley and Dan S. Johnston. 2021: Peter J. Kuipers; Scott P. Seidelmann; Dan S. Johnston; and Christine Mellon. 2020: Peter J. Kuipers; Scott P. Seidelmann; Dan S. Johnston; and Nhat H. Ngo. (2) Amounts reported in this column represent (i) the total compensation reported in the Summary Compensation Table for the applicable year in the case of Mr. Lipps and (ii) the average of the total compensation reported in the Summary Compensation Table for the applicable year for the Company’s NEOs reported for the applicable year other than Mr. Lipps. ​ (3) To calculate compensation actually paid, adjustments were made to the amounts reported in the Summary Compensation Table for the applicable year. A reconciliation of the adjustments for Mr. Lipps and for the average of the other NEOs is set forth following the footnotes to this table. ​ (4) Pursuant to rules of the SEC, the comparison assumes $100 was invested on December 31, 2019. Historic stock price performance is not indicative of future stock price performance. ​ (5) The TSR Peer Group consists of the NASDAQ Health Care Index, an independently prepared index that includes companies in the healthcare industry. ​ (6) As noted in the CD&A, for 2024, the Compensation Committee determined that non-GAAP EBITDA is a core driver of the Company’s performance and stockholder value creation and, accordingly, was utilized as a component for the annual performance-based cash bonus awards. Under the annual performance-based cash bonus awards, non-GAAP EBITDA for incentive purposes represents the Company’s as-reported non-GAAP EBITDA for each quarter and is defined as earnings before interest ​ income and expense, taxes, depreciation, amortization, and share-based compensation expenses pursuant to ASC Topic 718, as well as excluding certain other non-GAAP adjustments such as acquisition-related expenses, impairment and abandonment of operating lease right-of-use and other assets related to facilities, severance-related expenses, amortization of debt issuance costs, restructuring expenses, executive transition costs, ransomware-related insurance recoveries, legal and regulatory expenses, management severance costs, and gains on extinguishment of convertible senior notes, net.

Non-GAAP Measure Description | (6) As noted in the CD&A, for 2024, the Compensation Committee determined that non-GAAP EBITDA is a core driver of the Company’s performance and stockholder value creation and, accordingly, was utilized as a component for the annual performance-based cash bonus awards. Under the annual performance-based cash bonus awards, non-GAAP EBITDA for incentive purposes represents the Company’s as-reported non-GAAP EBITDA for each quarter and is defined as earnings before interest ​ income and expense, taxes, depreciation, amortization, and share-based compensation expenses pursuant to ASC Topic 718, as well as excluding certain other non-GAAP adjustments such as acquisition-related expenses, impairment and abandonment of operating lease right-of-use and other assets related to facilities, severance-related expenses, amortization of debt issuance costs, restructuring expenses, executive transition costs, ransomware-related insurance recoveries, legal and regulatory expenses, management severance costs, and gains on extinguishment of convertible senior notes, net. |  |  |  |
