Code of Business Conduct and Ethics

We adopted a Code of Business Conduct and Ethics (Code of Conduct), that is applicable to all of our employees and directors. The Code of Conduct is available on our website at www.argenx.com/investors/governance/rules-codes-compliance. The audit and compliance committee of our Board of Directors is responsible for overseeing the Code of Conduct and is required to approve any waivers of the Code of Conduct for employees and directors. We expect that any amendments to the Code of Conduct, and any waivers of its requirements, will be disclosed on our website.
