ASM starts €300 million share buyback program

Almere, The Netherlands
November 11, 2026, 8:00 a.m. CET

ASM International N.V. (Euronext Amsterdam: ASM) today announces that it will commence a share buyback program of ASM’s common shares of up to €300 million.
The program follows ASM’s announcement on October 27, 2026, that the Management Board authorized a new share buyback program of up to €300 million. It also follows the completion in September 2026 of ASM’s previous €150 million share buyback program. The new program reflects our company’s strong cash position and financial performance, and is part of ASM’s commitment to return excess cash to its shareholders.
The program commences on November 11, 2026, and is to end as soon as the aggregate purchase price of the common shares acquired by ASM has reached €300 million, but ultimately in October 2027.
The share buyback program will take place within the limits of relevant laws and regulations and the authority granted by shareholders at ASM’s Annual General Meeting, and will be executed by a third party. ASM intends to use the repurchased shares to cover existing and expected future obligations under its share-based compensation programs for employees and board members.
