Net Sales and Order Intake in the second quarter of 2006 were higher in both the Company’s Front-end and Back-end segments as compared to both the first quarter of 2006 and the second quarter of 2005.

Consolidated sales levels expressed in euro were negatively impacted by the weakened US dollar and US dollar related currencies against the euro. The decrease of exchange rates in the second quarter of 2006 as compared to the first quarter of 2006 impacted sales negatively by 3.9%.

The Gross Profit Margin for the second quarter of 2006 of 39.7% of net sales was 1.6 percentage points above the 38.1% gross profit margin realized in the first quarter of 2006. The increase is noticed in particular in the Company’s Front-end segment, primarily due to changes in the product mix, increased gross margins of most product lines, also due to higher utilization of our manufacturing and assembly facilities.

Selling, General and Administrative Expenses decreased 14% from € 35.8 million in the first quarter of 2006 to € 30.6 million in the second quarter of 2006 and increased 27% from € 24.1 million in the second quarter of 2005. Recorded in the first quarter of 2006 in our Front-end segment were impairment and restructuring charges of € 5.4 million with respect to the restructuring of ASM NuTool, explaining the decrease of selling, general and administrative expenses noticed.

The increase from the second quarter of 2005 was the result of increased sales and marketing activity, demo activity, and increased expenditures in preparing to meet requirements under section 404 of the Sarbanes-Oxley Act. In addition, the adoption of Statement of Financial Accounting Standards No. 123R “Share-Based Payment,” effective January 1, 2006, required us to recognize costs of employee stock options.

Liquidity and capital resources

Net cash provided by operations in the second quarter of 2006 was € 52.9 million as compared to net cash used in operations of € 3.9 million in the second quarter of 2005. For the six months ended June 30, 2006, net cash provided by operations was € 72.3 million compared to cash provided by operations of € 18.7 million for the same period in 2005. These developments result from increased net earnings and decreased working capital.

Net cash used in investing activities in the second quarter of 2006 was € 9.0 million, compared to € 6.9 million in the second quarter of 2005. For the six months ended June 30, 2006, net cash used in investing activities was € 17.7 million compared to € 18.8 million for the same period in 2005.

Net working capital, consisting of accounts receivable, inventories, other current assets, accounts payable, accrued expenses, advance payments from customers and deferred revenue, decreased from € 240.3 million at March 31, 2006 to € 229.9 million at June 30, 2006. The decrease is primarily the result of decreased levels of accounts receivable and inventory. The number of outstanding days of working capital, measured based on annual sales, decreased from 110 days at March 31, 2006 to 99 days at June 30, 2006.

At June 30, 2006, the Company’s principal sources of liquidity consisted of € 161.5 million in cash and cash equivalents, of which € 72.9 million was available for the Company’s Front-end operations and € 88.6 million was restricted for use in the Company’s Back-end operations. In addition, the Company also had € 109.1 million in undrawn bank facilities, of which € 31.5 million was available for its Back-end operations and € 27.3 million was available for the Front-end operations in Japan.

Outlook

The positive second quarter results show the continued strength of Back-end and the progress made by Front-end on its road to profitability, supported by a favorable customer and product mix.

Based on backlog and customer guidance, we expect Front-end sales for the second half of 2006 to be comparable to first half sales. We confirm that we expect to achieve for the full year 2006 the target of positive EBITDA (net of restructuring charges) as stated at the Annual General Meeting of Shareholders in May 2006.

For Back-end, based on the strong order intake in the past quarters, we expect solid sales and operating profit in the second half of 2006.

(1) The calculation of diluted net earnings (loss) per share reflects the potential dilution that could occur if securities or other contracts to issue common shares were exercised or converted into common shares or resulted in the issuance of common shares that would then share in earnings. Only instruments that have a dilutive effect on net earnings (loss) are included in the calculation. The assumed conversion results in adjustment in the weighted average number of common shares and net earnings (loss) due to the related impact on interest expense. The calculation is done for each reporting period individually. For the three months ended June 30, 2005, the effect of a potential conversion of convertible subordinated debt into 16,891,831 common shares was anti-dilutive and no adjustment has been reflected in the diluted weighted average number of common shares and net earnings for this period. Due to the loss reported in the six months ended June 30, 2005, the effect of securities and other contracts to issue common shares was anti-dilutive and no adjustment has been reflected in the diluted weighted average number of common shares and net loss for this period. For the six months ended June 30, 2006, the effect of a potential conversion of convertible subordinated debt into 11,886,738 common shares was anti-dilutive and no adjustment has been reflected in the diluted weighted average number of common shares and net earnings for this period.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

Basis of Presentation

ASM International N.V, (“ASMI”) follows accounting principles in the United States of America (“US GAAP”). Accounting principles applied are unchanged compared to the year 2005, except for the adoption of Statement of Financial Accounting Standard No. 123R “Share-based Payment” (“SFAS 123R”) effective January 1, 2006.

Principles of Consolidation

The Consolidated Financial Statements include the accounts of ASMI and its subsidiaries, where ASMI holds a controlling interest. The minority interest in subsidiaries is disclosed separately in the Consolidated Financial Statements. All intercompany profits, transactions and balances have been eliminated in consolidation. Intercompany profits included in inventory are recognized in the Consolidated Statements of Operations upon the sale of the respective inventory to a third party.

Option plans

ASMI adopted SFAS 123R effective January 1, 2006 and applies the provisions of SFAS 123R to all share-based payments, including employee stock options, granted, vested, modified or settled subsequent to January 1, 2006. SFAS 123R requires that the cost of all share-based compensation arrangements, be reflected in the financial statements based on the fair value of the awards. The cost is measured at fair value on the grant date and is recognized over the requisite service period.

Prior to January 1, 2006, ASMI applied the intrinsic-value method prescribed in APB No. 25, “Accounting for Stock Issued to Employees.” All stock options granted to employees had an exercise price equal to the market value of the underlying common shares on the date of grant and accordingly for these plans no stock-based compensation expense was reflected in financial statements.

RECONCILIATION US GAAP - IFRS

Accounting principles under IFRS

ASMI’s primary consolidated financial statements are and will continue to be prepared in accordance with US GAAP. However, ASMI is required under Dutch law to report its consolidated financial statements in accordance with International Financial Reporting Standards (“IFRS”).

The first consolidated financial statements prepared by ASMI in accordance with IFRS have been included in its Dutch Statutory Annual Report for 2005, including the consolidated financial statements of 2004 for comparison purposes. These consolidated financial statements replaced the consolidated financial statements ASMI prepared through 2004 in accordance with accounting principles generally accepted in the Netherlands (“Dutch GAAP”), included in its Dutch Statutory Annual Reports through 2004. As a result of the differences between IFRS and US GAAP that are applicable to ASMI, the Consolidated Statement of Operations and Consolidated Balance Sheet reported in accordance with IFRS differs from those reported in accordance with US GAAP. The major differences relate to accounting for goodwill, accounting for minority interest, accounting for convertible subordinated notes, accounting for development expenses and accounting for option plans.

The reconciliation between IFRS and US GAAP is as follows:
