ASM INTERNATIONAL ANNOUNCES DETAILS OF SHARE BUYBACK PROGRAM

Almere, The Netherlands
November 1, 2019, 8 a.m. CET

ASM International N.V. (Euronext Amsterdam: ASM) today announces the start of a share buyback program of ASMI's common shares up to €100 million.

This program follows on ASMI's announcement on July 23, 2019, that the Management Board authorized a share buyback program for up to €100 million. The program commences today, November 1, 2019, and will end as soon as the aggregate purchase price of the common shares acquired by ASMI has reached €100 million, but ultimately on November 19, 2020. ASMI strives to complete the program well before that date. The program will take place within the limitations of the authority granted by the Annual General Meeting of shareholders held on May 20, 2019. This share buyback program will be executed by a third party.

ASMI has the intention to reduce its capital by withdrawing the shares repurchased as part of  the new €100 million share buyback program, save for such number of treasury shares as may be necessary to fund ongoing share and option programs for employees and board members. The share repurchase program is part of ASMI's commitment to use excess cash for the benefit of its shareholders.

ASMI will update the market on the progress of the share buyback program on a weekly base, starting on November 11, 2019. This information will also be published on the ASMI website (www.asm.com).
