On February 28, 2024, our Board of Directors approved and adopted an updated Code of Conduct and Ethics (the “Code”). The Code supersedes our existing Code of Conduct and Compliance Plan, effective immediately. The Code was adopted as a regular, periodic refresh of our policies and did not relate to or result in any explicit or implicit waiver of any provisions of the prior code. The amendments included in the Code are intended to reflect the increasingly global nature of BioCryst, to streamline and update the discussion of applicable laws and regulations, and to improve its readability and organization. The Code applies to all employees and members of our Board of Directors.

We expect our employees to conduct their scientific and business activities in a manner consistent with the highest ethical, professional and legal standards. Continued adherence to these high standards is the responsibility of all employees and directors and is absolutely necessary for BioCryst's continued success.
