Item 16B. Code of Ethics

Item 16B Code of Conduct

We have established a Code of Conduct to ensure that the members of our Board of Directors and Executive Committee and all employees and external staff (such as consultants, interns, students, etc.) are making ethical and compliant decisions and are acting with integrity and respect for human rights when conducting our business and performing their day-to-day duties.

The Code of Conduct addresses topics such as anti-bribery and anti-corruption, anti-discrimination and anti-harassment, human rights, conflicts of interest, speak up, and responsible behavior.

We expect any conflicts to be addressed appropriately, and any breaches of the Code to be prevented. To this end, we provide various trainings, including Code of Conduct training to all employees and external staff. This year, 97% of the new employees and external staff completed the Code of Conduct training, and this percentage is measured against all new employees and external staff. We will continue to provide ongoing compliance and ethics trainings to strengthen awareness and support ethical decision-making.

Our Code of Conduct is available on our website at www.glpg.com/investors/corporate-governance/.

In 2025, three breaches of our Code of Conduct were escalated to the Audit Committee. Appropriate measures were taken to address these breaches.
