Prime Success responds to Sinovac Biotech in letter to fellow shareholders

Prime Success, a significant shareholder of Sinovac Biotech (SVA) with ownership of approximately 8% of the Company’s outstanding shares, issued the following letter in response to the Company’s recent “false and misleading claims” relating to the upcoming Special Meeting of Shareholders scheduled for July 8, 2025. “Prime Success, L.P., a significant shareholder of Sinovac Biotech, continues to be disappointed by the current Board’s distortion of the facts about what is at stake at the upcoming Special Meeting of Shareholders scheduled for July 8, 2025. In our June 10 letter we addressed several of the 1Globe Activist Board’s misstatements and are taking the opportunity to remind all shareholders why the 1Globe Activist Board cannot be trusted: 1. Prime Success is insisting that a dividend be distributed – for all shareholders… 2. The Globe Activist Board is deliberately baiting shareholders by setting the dividend distribution date for one day after the Special Meeting. We call upon the Company to make dividend distribution before the Special Meeting… 3. The 1Globe Activist Board distorts historic facts to aggrandize 1Globe and smear legitimate investors… 4. Shareholders: looking forward, it’s time to focus on what truly matters – the future of your investment in Sinovac.”
