In connection with the conclusion of his service as the Company’s President and Chief Executive Officer, Dr. Chang will be eligible for certain severance benefits under the terms of the Company’s Change in Control and Severance Benefit Plan (the “Severance Plan”) as described under “Executive Compensation—Potential Payments and Benefits Upon Termination or Change in Control” in the Company’s definitive proxy statement on Schedule 14A, filed with the Securities and Exchange Commission on April 30, 2026 (the “Proxy Statement”).
