ASM International N.V. (Euronext Amsterdam: ASM) today announces that Mr Martin van den Brink has resigned as a member of ASM’s Supervisory Board with immediate effect.

The resignation follows an assessment that Mr Van den Brink’s other professional activities could, over time, give rise to overlapping interests. To avoid any such situation, or any appearance of it, arising in the future, the decision was taken by mutual understanding and agreement. Mr Van den Brink was appointed to ASM’s Supervisory Board in May 2024.
Pauline van der Meer Mohr, Chair of ASM’s Supervisory Board, said: “On behalf of the Supervisory Board, I would like to thank Martin for his very significant contributions to ASM. He played an important role in strengthening the Supervisory Board’s technology oversight, including through the establishment of the Technology Committee, and his deep industry knowledge and experience have been of great value to the company. While we regret that he is stepping down, we respect the decision taken and wish him every success in his ongoing and future endeavors.”
