SINOVAC Updates on Antigua High Court Order and Auditor Engagement

Sinovac Biotech provided an update on the Antigua High Court's order, which now requires the company's board to remain unchanged until the trial in late April/early May 2026. The company also announced the engagement of Zhonghua Certified Public Accountants LLP as its independent auditor and registered public accounting firm, replacing UHY LLP. This change supports Sinovac's focus on financial reporting and audit workstreams and its commitment to maintaining compliance with US SEC and Nasdaq requirements.
