The Rule 10b5-1 trading arrangement contemplated, as of the adoption date, the sale of up to 393,260 shares of common stock; however, 373,382 of such shares may be sold pursuant to a prior Rule 10b5-1 trading arrangement that will expire prior to the commencement of sales under the plan adopted on September 3, 2024. The Rule 10b5-1 trading arrangement also contemplated, as of the adoption date, the sale of up to 801,408 shares of common stock subject to RSUs previously granted to Ms. Schaub that will vest or vested at various dates between September 15, 2024 and October 15, 2025, as well as an unknown number of shares to be purchased in the future pursuant to the Company’s Employee Stock Purchase Plan. The aggregate number of Ms. Schaub’s RSU shares that will be available for sale under the Plan is not yet determinable because the shares available will be net of shares sold to satisfy tax withholding obligations that arise in connection with the vesting and settlement of such RSU awards.

(4)At the time of adoption, the maximum number of shares that could be sold was unknown. The trading arrangement contemplated, as of the adoption date, the sale of up to 414,489 shares of common stock. This number included up to 116,841 shares of common stock subject to RSUs previously granted to Ms. Schwartz that vested or will vest at various dates between September 15, 2024 and October 15, 2025.

As such, for purposes of this disclosure, the shares included in this table reflect the shares held by Ms. Schwartz plus the aggregate maximum number of shares underlying Ms. Schwartz’s RSUs without excluding the shares that will be sold to satisfy the tax withholding obligations.
