 of Stockholders is first made by the Company. You are also advised to review the Company’s amended and restated bylaws, which contain additional requirements relating to advance notice of stockholder proposals and director nominations.

In addition to satisfying the deadlines in the “advance notice” provisions of our bylaws, to comply with the universal proxy rules, stockholders who intend to solicit proxies in support of director nominees other than the Company’s nominees must include in their notice the information required by Rule 14a-19 under the Exchange Act.

Notices of any proposals or nominations for the Company’s 2026 Annual Meeting of Stockholders should be sent to the Corporate Secretary of the Company at 989 East Hillsdale Boulevard, Suite 300, Foster City, California 94404.

#### Householding of Proxy Materials
The SEC has adopted rules that permit companies and intermediaries (e.g., brokers) to satisfy the delivery requirements for Notices of Internet Availability of Proxy Materials or other Annual Meeting materials with respect to two or more stockholders sharing the same address by delivering a single Notice of Internet Availability of Proxy Materials or other Annual Meeting materials addressed to those stockholders. This process, which is commonly referred to as “householding,” potentially means extra convenience for stockholders and cost savings for companies.

A number of brokers with account holders who are Company stockholders will be “householding” the Company’s proxy materials. A single Notice of Internet Availability of Proxy Materials will be delivered to multiple stockholders sharing an address unless contrary instructions have been received from the affected stockholders. Once you have received notice from your broker that they will be “householding” communications to your address, “householding” will continue until you are notified otherwise or until you revoke your consent. If, at any time, you no longer wish to participate in “householding” and would prefer to receive a separate Notice of Internet Availability of Proxy Materials, please notify your broker or the Company by telephone at (650) 667-4085 or by written request to 989 East Hillsdale Boulevard, Suite 300, Foster City, California 94404, Attention: Corporate Secretary, and we will promptly deliver the requested documents or notice. Stockholders who currently receive multiple copies of the Notices of Internet Availability of Proxy Materials at their addresses and would like to request “householding” of their communications should contact their brokers.
