ASM International N.V. Announces Receipt of Confirmation from Mellon that it has no Support of Other Shareholders for the Proposal to Split the Company

BILTHOVEN, the Netherlands, October 18, 2006 --- ASM International N.V. (Nasdaq: ASMI and Euronext Amsterdam: ASM) said that, in response to questions put to Mellon HBV Alternative Strategies (Mellon) by ASMI’s legal advisers, Mellon confirmed that it has no support of other shareholders for its proposal that the Company spins-off its back-end operations.
ASMI felt that it should ask these questions following reports in the media stating that Mellon claims the support of shareholders who own over 30% in ASMI in its efforts to split the Company. It follows from Mellon’s response to these questions that these reports are untrue. ASMI believes that it is important that false rumors of this nature should not affect the trading of its shares. For this reason ASMI believes it is appropriate that Mellon’s response to ASMI’s questions seeking verification of these rumors are shared with the market.
On the basis of information filed by Mellon with the US Securities and Exchange Commission, the Company believes that Mellon currently controls 3,731,235 shares, equal to approximately 7% of the Company’s 53,489,824 shares outstanding.
