ARGENX SE

CODE OF ETHICS

We adopted a Code of Business Conduct and Ethics (Code of Conduct), that is applicable to all of our employees and

directors. Our Code of Conduct translates the core values into a set of clear standards to help guide our conduct as we

navigate the complexities of the highly regulated and competitive global marketplace in which we operate as we work to

become an independent, fully integrated, and global immunology company. Its purpose is not to exhaustively list all the

behaviors we as a company expect from each other. Rather, the Code of Conduct contains key principles for us to live by

as individuals, to ensure that we maximally contribute to argenx’s collective success. [As part of their onboarding, all

employees receive a training on the Code of Conduct and the Directors receive a copy of the Code of Conduct and need

to comply with its terms.] The Code of Conduct is available on our website atwww.argenx. com/investors/governance/

rules-codes-compliance. The Audit and Compliance Committee of our Board of Directors (i) is responsible for

overseeing and evaluating the Code of Conduct and (ii) is required to approve any waivers of the Code of Conduct for

employees and directors. The Audit and Compliance Committee has not received requests for material waivers of the

Code of Conduct in the financial year 2025. We expect that any amendments to the Code of Conduct, and any waivers of

its requirements, will be disclosed on our website.
