2. The price reported in Column 4 is a weighted average price. These shares were sold in multiple transactions at prices ranging from $19.89 to $20.87, inclusive. The reporting person undertakes to provide to the Issuer, any security holder of the Issuer, or the staff of the SEC, upon request, full information regarding the number of shares sold at each separate price within the ranges set forth in footnotes (2) and (3) to this Form 4.

3. The price reported in Column 4 is a weighted average price. These shares were sold in multiple transactions at prices ranging from $20.92 to $21.19, inclusive.

4. Shares sold to satisfy tax obligations in connection with the vesting of previously granted Restricted Stock Units.

5. The shares are represented by restricted stock units (RSUs).

One-twelfth (8.33%) of the total RSUs will vest on May 15, 2026 and the remainder will vest in 11 equal quarterly installments (August, November, February and May) of one-twelfth thereafter (8.33% of the total RSUs will vest per quarter), in each case subject to the Reporting Person's continued service with the Issuer through each applicable vesting date.
