BILTHOVEN, THE NETHERLANDS, October 27, 2005 - ASM International N.V. (NASDAQ: ASMI and Euronext Amsterdam: ASM) reports today its 2005 third quarter operating results. These operating results have been prepared in accordance with accounting principles generally accepted in the United States of America ("US GAAP").

In making the announcement, Arthur del Prado, President and CEO, stated, "As indicated in our prior guidance, ASM third quarter operating results declined sequentially, primarily reflecting the lower backlog for the Front-end segment at the end of the second quarter of 2005. Third quarter bookings, however, increased for the third consecutive quarter. The 13.4% quarter-over-quarter order improvement, included gains in both Front-end and Back-end segments bookings. Overall, our book-to-bill ratio was 1.15 with our Front-end segment realizing a strong order intake and our Back-end segment recording a book-to-bill of just under 1. We built backlog during the quarter, ending with € 223.5 million, a 13.7% increase over the second quarter."

The consolidated financial statements for the third quarter of 2005 and nine months ended September 30, 2005 include the operations of the Company's wholly owned subsidiaries ASM NuTool, Inc. and ASM Genitech, Inc., which were acquired in June 2004 and August 2004, respectively.

Net sales in the third quarter of 2005 were lower as compared to both the second quarter of 2005 and the third quarter of 2004. The strengthening of the US dollar and US dollar related currencies against the euro in the third quarter of 2005 compared to the second quarter of 2005 impacted sales positively by 4.0%. The increase in currency exchange rates in the third quarter of 2005 compared to the third quarter of 2004 impacted sales positively by 0.6%.

As a percentage of net sales, selling, general and administrative expenses in the third quarter of 2005 were 15.3%, as compared to 13.1% in the second quarter of 2005 and 15.3% in the third quarter of 2004.

As a percentage of net sales, research and development costs in the third quarter of 2005 were 13.6%, as compared to 13.0% in the second quarter of 2005 and 12.0% in the third quarter of 2004.

Amortization of purchased technology and other intangible assets mainly relates to the amortization of purchased technology and other intangible assets from the acquisitions of ASM NuTool and ASM Genitech.

Net interest expense was € 2.4 million in the third quarter of 2005, down € 0.4 million as compared to net interest expenses in the second quarter of 2005 and up € 0.2 million as compared to net interest expenses in the third quarter of 2004. When compared to the third quarter of 2004, interest expenses increased due to increased borrowings, including the issuance of US$ 150.0 million in convertible debt in December 2004. This increased interest expense was almost fully offset by increased interest income, which was due to increased cash and cash equivalents and increased interest rates for US dollar cash deposits.

The net loss for the third quarter of 2005 amounted to € 6.3 million, or € 0.12 diluted net loss per share, compared to net earnings of € 3.7 million or € 0.07 diluted net earnings per share for the same period in 2004.

For the third consecutive quarter, order intake improved when compared to the previous quarter.
Nine months ended September 30, 2005.

Net Sales of € 492.5 million for the nine months ended September 30, 2005 decreased 16.8% as compared to € 591.6 million in the same period in 2004.

Consolidated sales levels expressed in euro were negatively impacted by the strengthened euro against the US dollar and US dollar related currencies. The decline in exchange rates in the nine months ended September 30, 2005 compared to the nine months ended September 30, 2004 impacted sales negatively by 2.5%.

Gross Profit Margin amounted to 34.9% of net sales in the nine months ended September 30, 2005. The decrease of 3.3 percentage points as compared to the same period in 2004 was caused by lower volumes and an increase in the proportion of net sales accounted for by the lower margin Front-end segment. In addition, the gross profit margin of the Front-end segment decreased due to changes in the product mix.

ASM Front-End Manufacturing Singapore ("FEMS") focuses on manufacturing generic subassemblies and components for Front-end systems at lower costs. The project is on track.

Selling, General and Administrative Expenses decreased 9.3% from € 82.1 million in the nine months ended September 30, 2004 to € 74.5 million in the nine months ended September 30, 2005. The decrease is mainly the result of lower commercial activities in the Back-end segment. Favourable currency exchange rates also contributed to the decrease. Selling, general and administrative expenses reported by the Front-end segment are stable as a result of the Company's focus on fixed cost control.

As a percentage of net sales, selling, general and administrative expenses were 15.1% in the nine months ended September 30, 2005, compared to 13.9% in the same period in 2004. The increase is the result of lower net sales.

Research and Development Expenses increased 9.1% from € 62.7 million in the nine months ended September 30, 2004 to € 68.5 million in the nine months ended September 30, 2005. The increase is the result of increased research and development activities, the inclusion of the operations of the Company's subsidiaries ASM NuTool and ASM Genitech, which were acquired in June 2004 and August 2004 respectively, and the full consolidation of the operations of the Company's subsidiary NanoPhotonics as of January 1, 2005.

For the nine months ended September 30, 2005, net cash provided by operations was € 29.6 million compared to cash provided by operations of € 79.2 million for the same period in 2004.

For the nine months ended September 30, 2005, net cash used in investing activities was € 33.1 million compared to € 46.3 million for the same period in 2004. The decrease is mainly caused by acquisitions in 2004 and decreased capital expenditures in 2005.

The increase is primarily the result of increased order intake, resulting in increased inventory levels. The number of outstanding days of working capital, measured based on annual sales, increased from 116 days at June 30, 2005 to 122 days at September 30, 2005.

Outlook

During the fourth quarter of 2005, we intend to complete our evaluation of the strategic options for ASM NuTool, which will include a review of the valuation of ASM NuTool assets. Excluding potential effects from this evaluation, our fourth quarter Front-end segment results should show improvement over the third quarter. Based on current order backlog, we expect increased sales in our Front-end segment, though we do not expect to be break-even in Front-end in the fourth quarter. Our Back-end segment has continued to outperform its peers and to strengthen its market position in 2005. Assuming that the markets of our Back-end segment stay at the current levels, we expect the result in the fourth quarter to be above the average of the first three quarters of 2005.
