Frequently Asked Questions
The BIOSECURE Act is proposed US legislation that would restrict federal funding and contracts for biotech companies deemed to pose national security risks, specifically targeting Chinese firms including WuXi AppTec, WuXi Biologics, BGI, and others. If enacted, it would significantly impact WuXi's US revenue and potentially reshape global pharma services supply chains.
As of 2025, the BIOSECURE Act has passed the House but has not been enacted into law. WuXi AppTec has been lobbying against it and diversifying its client base away from US dependency. However, the regulatory risk remains significant and represents the company's biggest challenge.
