ASM International Announces Total Number of Shares Eligible for Voting at AGM; Court Rules No Vote on Hermes Proposals

Market Wire, May, 2008

ASM International N.V. (NASDAQ: ASMI) (Euronext Amsterdam: ASM) announces that a total of 38,996,653 common shares have been registered for the Annual General Meeting of Shareholders scheduled for today, May 21, 2008, in the Netherlands at 14:00 CET. Based on a total of 51,721,280 common shares outstanding that can be voted, the total number of common shares registered for voting represents 75.4% of the total common shares outstanding. Additionally, the 21,985 preferred shares have been registered, bringing the maximum number of votes to be cast at the meeting to 60,981,653.

The number of common shares outstanding has been influenced by:

1) The recent Company buyback of 2.4 million shares for approximately EUR 32 million (excluding the potential dividend withholding tax). The repurchase is funded by the EUR 25 million cash dividend received from ASM Pacific Technology Ltd in April 2008 with the remaining amount funded by part of the ASMPT cash dividend expected in August 2008.

2) The conversion of US$6.2 million nominal amount of the 41/4% convertible subordinated notes due 2011 into 0.3 million shares.

Enterprise Court Decision

The Netherlands Enterprise Court ruled yesterday that there will be no vote at today's AGM on the Hermes proposals (Item 6 of the Agenda).
