SELLING SECURITYHOLDERS
This prospectus supplement is filed solely for the purpose of including selling securityholders who have acquired Common Stock included for resale in this Prospectus from certain existing selling securityholders whose shares were previously registered for resale in the S-1. Where the name of a selling securityholder identified in the table below also appears in the table in the Prospectus (i.e., Dr. Parag Mallick), the information set forth in the table below regarding that selling securityholder supersedes and replaces the information regarding such selling securityholder in the Prospectus. Information regarding the selling securityholders listed in the table below, including the number of shares of Common Stock beneficially owned by them, is based on information provided by such selling securityholders as of the date of this prospectus supplement. The percentage of beneficial ownership after the offered shares of Common Stock are sold is calculated based on 124,166,776 shares of Common Stock outstanding as of October 31, 2021.
Information about the selling securityholders, including those listed below, may change over time. Since the effectiveness of the Registration Statement on Form S-1 of which the Prospectus is a part, certain securityholders may have sold or otherwise transferred their securities registered thereunder. This prospectus supplement does not provide any updates with respect to any sales or transfers, except for those expressly disclosed in the table below. As of December 21, 2021, the Selling Securityholders table included under the section “Selling Securityholders,” which begins on page 136 of the Prospectus, is revised to amend the information solely with respect to the following selling securityholders:
