主题：购买科兴有限公司股份的报价

尊敬的投资者：

您好！ 我叫Jacob Mohs，是Alternative Liquidity Capital的管理合伙人。我们有意购买您在科兴控股生物技术有限公司（“科兴”）的股份。

自2019年2月22日以来，科兴在纳斯达克的公开交易一直停牌。2022年年度报告指出“无法保证停牌何时解除，或是否会解除”。因此，投资者可能很难有机会出售他们的股份。

所幸, 您现在有机会迅速将您的科兴股份变现。请找附上的我们购买科兴的报价，价格为每股0.03美元。

我们的目标是让这个报价对您尽可能方便。附上了一份委托书，您可以使用它来提交您的股份。如果您选择将股份卖给我们，请按照附上的说明完成并执行此委托书，然后将其退还给购买方。在提交股份之前，请仔细阅读整个购买报价。

所提供的购买价格仅基于购买方对股份价值的独立评估，完全基于公开信息。鼓励所有提交股份的股东在决定接受此报价之前进行独立的估值分析。

如果您今天行动，您就有机会参与此次机会。一旦公司或其过户代理确认股份已经正确过户，我们将发送付款。除非延长，我们的报价将于2024年2月21日晚上11:59纽约时间到期。

如果您有任何问题，请随时通过info@alternativeliquidity.net或(888) 884-8796与我们联系。

顺祝商祺，
