(1) Sheri L. Dodd was our PEO in 2024 starting on July 1, 2024, and Daniel L. Reuvers served as our PEO in 2024 through June 30, 2024 and in each of 2023, 2022 and 2021, as well as in 2020 starting on June 8, 2020. Gerald R. Mattys served as our PEO in 2020 through June, 8 2020. In 2024, Elaine M. Birkemeyer, Kristie T. Burns and Sherri L. Ferstler were our Non-PEO NEOs. In 2023, Elaine M. Birkemeyer, Kristie T. Burns, Sherri L. Ferstler and Brent A. Moen were our Non-PEO NEOs. In 2022 and 2021, Brent A. Moen, Kristie T. Burns and Eric Pauls were our Non-PEO NEOs. In 2020, Brent A. Moen, Robert J. Folkes and Bryan Rishe were our Non-PEO NEOs. (2) The dollar amounts reported represent the Compensation Actually Paid (“CAP”) to the NEOs in accordance with, and using the adjustments set forth in, Item 402(v) of Regulation S-K. The following adjustments related to equity awards were made to their total compensation each year as reported in the Summary Compensation Table (“SCT”) to determine the CAP: Reconciliation of PEO Summary Compensation Table Total to Compensation Actually Paid

​ (3) Our peer group for the calculation of total stockholder return (“TSR”) is the S&P Healthcare Equipment Select Industry Index, which is the industry index used in our stock price performance graph in our Form 10-K for the fiscal year ended December 31, 2024. TSR, in the case of both the Company and our peer group, reflects the cumulative return on $100 as if invested on December 31, 2019, including reinvestment of any dividends. (4) Our company-selected measure, which we believe represents the most important financial performance measure (that is not otherwise required to be disclosed in the table) used by the Company to link CAP to the NEOs for 2023 to company performance, is revenue. Revenue is one of the metrics under both the 2024 annual cash incentive program and the 2024 PSUs. In order to calculate CAP, the following amounts were excluded from or added to the SCT total compensation: Current PEO ​

​ In connection with his appointment as CEO in 2020, Mr. Reuvers received a grant of stock options that included a market condition related to stock price in order to vest. Due to that market condition, the grant date fair value of those stock options was determined using the Monte Carlo Simulation model. The market condition was satisfied in the first quarter of 2021, and as a result, we have used the Black-Scholes valuation model (which is the valuation model used for all other stock option awards we have granted) to value these stock options for all dates subsequent to the grant date as part of the CAP calculations.
