(the "Company"), which will be held on December 22, 2025. To the extent the information set forth herein differs from or updates information contained in the Proxy Statement, the information set forth herein shall supersede or supplement the information in the Proxy Statement, which shall be read in its entirety. All other information in the Proxy Statement remains unchanged.

On December 1, 2025, Broadridge Financial Solutions, Inc., the Company's proxy agent, commenced mailing the proxy materials for the Annual Meeting, including the proxy card (the "Proxy Cards") relating to the Annual Meeting. The Proxy Card references a certain virtual meeting site under the domain name "virtualshareholdermeeting.com" set up by the Company for the Annual Meeting.

However, the Company has not and will not set up any virtual meeting site under such domain name for the Annual Meeting. As disclosed in the Proxy Statement, the Annual Meeting will continue to be held at the offices of the Company at 15375 Barranca Parkway C106, Irvine, CA 92618 and virtually via the Internet, for which a stockholder must register in advance at https://forms.cloud.microsoft/r/mwd9tmKBbL. A stockholder may not be able to attend the Annual Meeting virtually if the stockholder does not register in advance via the link.

The voting and tabulations for the Annual Meeting will not be affected by the reference in the Proxy Card to the virtual meeting site.

There is no change to the location, the purpose or any of the proposals to be acted upon at the Annual Meeting.

The Record Date for determining the stockholders entitled to receive notice of and to vote at the Annual Meeting remains the close of business on November 28, 2025. Stockholders as of the Record Date who have previously submitted their proxies or otherwise voted and who do not want to change their vote need not take any action. Stockholders who have not yet done so are encouraged to vote as soon as possible.
