Executive Summary
Applied Optoelectronics filed a DEFA14A supplement to its definitive proxy statement to update shareholders on a change in independent auditor.

The filing updates Proposal No. 2 at the June 4, 2026 annual meeting to seek ratification of PwC's appointment instead of Grant Thornton.
