Louvain-la-Neuve (Belgium), 11 March 2020: IBA (Ion Beam Applications SA), the world's leading provider of proton therapy solutions for the treatment of cancer, announces the results of the Extraordinary General Meeting of its shareholders on 10 March 2020.

IBA is firmly committed to operating its business in a responsibly sustainable manner and has now committed this approach as a cornerstone of its articles of association. The Company has a long tradition of valuing all of its stakeholders through a consistent sustainability philosophy. This has now been cemented into its mission and decision-making process both at the Board and Management levels. This statutory stakeholder approach is an important step in IBA's journey towards a model that creates shared and sustainable benefits for all its stakeholders: customers, patients, employees, shareholders, the community at large and the planet.
