BILTHOVEN, The Netherlands, March 29, 2006 — The Supervisory Board of ASM International N.V. (NASDAQ:ASMI; Euronext Amsterdam: ASM) announced today that it will propose one new Supervisory Board member, Berend C. Brix, and two additional Management Board members, Charles (Chuck) D. del Prado and Han F. M. Westendorp, at the company’s General Annual Meeting of Shareholders on May 18, 2006.

Berend C. Brix, a partner in Lesuut Finance B.V., a Netherlands-based management consultancy, previously served as Chairman of the Management Board of Cap Gemini Ernst & Young. He is currently Vice-Chairman of the Supervisory Board, and Chairman of the Audit Committee of Getronics N.V., a leading supplier of information and communications technology solutions and services. Mr. Brix is also a member of the Supervisory Boards of the ANP, the Netherlands National News Agency, and Koninklijke Swets & Zeitlinger Holding N.V., a distributor of scientific journals.

The Supervisory Board further intends to appoint Mr. Brix to the Audit Committee upon his election to the Board. The Board also nominates Eric A. van Amerongen for reappointment to the Supervisory Board where he serves as Vice-Chairman and Chairman of the Selection, Appointment and Remuneration Committee. Mr. van Amerongen will step down as an Audit Committee member.

The nominees for the Management Board, Chuck del Prado, President and General Manager of ASM America, and Han Westendorp, Chief Operating Officer Front-end Operations of ASM International, have held their present positions at ASMI since 2003.

An engineer and technology manager, Chuck D. del Prado (44) has eighteen years’ experience in the computer and semiconductor industries. Prior to joining ASM International as Director of Marketing, Sales and Service of ASM Europe in 2001, he spent five years as a manager in sales and manufacturing with ASM Lithography, in Taiwan and the Netherlands. He began his career at IBM Nederland N.V. where he served in a variety of sales and account management positions. Mr. del Prado received a Master-of-Science degree, with a concentration in industrial engineering, computer science and technology management.

Han F. M. Westendorp (49) has had two careers with ASMI. During the 1980s, Mr. Westendorp was instrumental in developing ion implant technology at ASMI. During the

following decade, he held various management positions at Tokyo Electron Massachusetts, latest as General Manager, before rejoining ASMI in 1999 as General Manager of ASM Europe. Mr. Westendorp holds a doctorate degree in physics and mathematics from Utrecht University in the Netherlands.

Under Netherlands law, public-traded companies are required to have a two-tier board structure: a Supervisory Board that is composed entirely of non-executive members, and a Management Board comprised of senior company officials.
