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 February 25, 2020, that the Management Board authorized a share buyback program for up to €100 million. The program commences today, June 2, 2020, 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 17, 2021.

The Board concluded, after a thorough analysis in light of the increased economic uncertainty due to the COVID-19 pandemic, that the company’s financial position provided sufficient strength to both continue investments in the growth of the business, which is the key priority, and to proceed with the previously announced dividends, which were paid in May 2020, and share buyback program. The Board will remain closely monitoring the company’s financial position.

The share buyback program will take place within the limitations of the authority granted by the shareholders during the Annual General Meeting which was held on May 18, 2020. 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 this 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.

ASMI will update the market on the progress of the share buyback program on a weekly base, starting on June 8, 2020. This information will also be published on the ASMI website (www.asm.com).
