On March 13, 2026, the Issuer repurchased 127,523 shares of the Reporting Person's Common Stock at the fair market value of the Issuer's Common Stock as of March 13, 2026 (for an aggregate purchase price of $4,876,106) as repayment for the Reporting Person's promissory note.

The 2020 Note accrues non-compounding interest at a rate of 4.0% per annum and matures seven years following the date of issuance, unless earlier converted pursuant to its terms. At the execution of the underwriting agreement in connection with the IPO, the outstanding principal balance of the 2020 Note plus any accrued and unpaid interest automatically converted into shares of Common Stock at a ratio based on a conversion price equal to $340.0 million plus any consideration paid by the noteholder for the 2020 Note divided by the Issuer's fully-diluted capitalization on August 5, 2020. Represents an award of restricted stock units ("RSUs"), which vests on the earlier of (i) the one-year anniversary of the award's vesting commencement date and (ii) immediately before the Issuer's first annual meeting following the award's vesting commencement date, subject to the Reporting Person's continuous service to the Issuer. Represents the withholding of shares of Common Stock upon the exercise of the Stock Warrant; not an open market transaction.
