°       The Front-end segment increased its operating profit from EUR 18.7 million to EUR 20.8 million quarter-to-quarter. Q2 2010 showed an operating profit of EUR 3.6 million (including EUR 3.3 million restructuring charges);

·     Second quarter 2011 net earnings were EUR 50 million compared to net earnings of EUR 40 million for the first quarter of 2011 and EUR 48 million for the second quarter of 2010. Net earnings of both previous quarter and the second quarter last year included effects of the revaluation of the conversion option. Excluding this revaluation net earnings were EUR 45 million for the previous quarter and EUR 34 million for the second quarter of 2010.

• Book to bill in the second quarter was 0.7, both in the Front-end and the Back-end segment. The Backlog decreased from Euro 579 million at the end of the first quarter to EUR 436 million at the end of the second quarter.

Comment
Commenting on the results, Chuck del Prado, President and Chief Executive Officer of ASM International, said, "The second quarter sales came in at a record level. As well in the Front-end as in the Back-end we recorded an all-time high sales level, leading to an EPS of EUR 0.84. The quarter showed again a strong performance of the newly acquired AS business".

Outlook
The current market uncertainty leads to a situation whereby our customers are taking more time to assess their overall capacity plans. This has led in Q2 as compared to Q1 to a lower order intake for our Back-end and Front-end operations. We do not expect that this situation will improve in the 3^rd quarter. Taking our current backlog into account, we expect that this will lead to a sales decrease in Q3, both for our Back-end and Front-end operations.
