Convertible Notes

For our Convertible Notes, the dilutive effect has been calculated using the if-converted method. Upon surrender of the Convertible Notes for conversion, Merit will pay cash up to the aggregate principal amount of the Notes to be converted and pay or deliver, as the case may be, cash, shares of Common Stock or a combination of cash and shares of Common Stock, at Merit’s election, in respect of the remainder, if any, of Merit’s conversion obligation in excess of the aggregate principal amount of the Convertible Notes being converted. Under the if-converted method, we include the number of shares required to satisfy the remaining conversion obligation, assuming all the Convertible Notes were converted. The convertible notes only have an impact on diluted earnings per share when the average share price of our Common Stock exceeds the conversion price of $86.83. The average closing price of the Common Stock for the three and nine-month periods ended September 30, 2026 and 2025, respectively, was used as the basis for determining the dilutive effect on EPS.
