Comment

Commenting on the results, Chuck del Prado, President and Chief Executive Officer of ASM International, said: “Sales in Q2 are showing a growth as compared to Q1, this is driven by the Back-end operations. The sales decrease in the Front-end operations is in line with our previous guidance. Bookings improved both in the Front-end and Back-end. While total results in Q2 showed an improvement as compared to Q1, Front-end efficiency issues were still strongly impacting the results. We expect that improvements will become visible in the second half of the year.”

Outlook

For the current quarter we expect a sales increase in our Front-end operations. For our Back-end operations, based upon the actual backlog, a sound quarter is expected.

Diluted (1)		65,023			55,650			64,733			55,604

(1) The calculation of diluted net earnings per share reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that then shared in earnings of the Company. Only instruments that have a dilutive effect on net earnings are included in the calculation. The assumed conversion results in adjustment in the weighted average number of common shares and net earnings due to the related impact on interest expense. The calculation is done for each reporting period individually. Both for the three months ended June 30, 2012 and for the six months ended June 30 2012, the effect of a potential conversion of convertible debt into 9,074,410 common shares was anti dilutive and no adjustments have been reflected in the diluted weighted average number of shares and net earnings per share for these periods. The possible increase of common shares caused by employee stock options for the three months ended June 30, 2012 with 379,978 common shares and for the six month ended June 30, 2012 with 333,666 common shares, adjustments have been reflected in the diluted weighted average number of shares and net earnings per share for this period.

Amounts are rounded to the nearest thousand euro; therefore amounts may not equal (sub) totals due to rounding.

ASM INTERNATIONAL N.V.

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”). 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 differ from those reported in accordance with US GAAP. The major differences relate to development costs, goodwill, inventory obsolescence reserve, pension plans and preferred shares.

The reconciliation between IFRS and US GAAP is as follows:
