ASM INTERNATIONAL N.V. REPORTS FIRST QUARTER 2014 RESULTS

Almere, The Netherlands
April 23, 2014

FINANCIAL HIGHLIGHTS

The pro-forma figures ¹⁾ show ASMI numbers whereby ASMPT is deconsolidated.

• Net sales for the first quarter 2014 increased with 19% compared to the fourth quarter and increased with 88% year-on-year, mainly driven by ALD and PEALD sales which were substantially higher than in the comparable periods last year.
   
• Net earnings improved due to strong margin improvement, caused by high sales and positive mix effects and the improvement in the result from investments, which in Q4 included €4.0 million restructuring charges in ASMPT.

¹⁾  Following the close of the sale on March 15, 2013 of a 12% share in ASMPT, the entity in which the Back-end segment is organized, ASMI's shareholding is reduced to 40%. As a consequence, as from March 15, 2013 the results of ASMPT are deconsolidated. From that date onwards the net result of ASMPT is reported on the line 'result from investments'. In 2013 a purchase price allocation took place, which was finalized in the fourth quarter, resulting in the recognition and subsequent amortization of certain intangible assets.

COMMENT

Commenting on the results, Chuck del Prado, President and Chief Executive Officer of ASM International said:
"Q1 2014 was the best quarter for ASMI Front-end in its history. Order intake was with €172 million at a record level, an increase of 29% compared to the previous quarter, while sales increased with 19%. Again ALD and PEALD were the main drivers for the order intake and for sales. Our gross margin, due to high sales, a very strong mix and as an effect of supply chain changes made in the past years, reached a level of more than 43%. While cost remained stable quarter on quarter, operating result margin surpassed the 20% level. Free cash flow of €60 million was driven by the operating result in combination with strong improvements in working capital."

OUTLOOK

For Q2 2014 we expect for sales a low single digit decrease, on a currency comparable base. For the second half of 2014, the current visibility remains limited. After the very high order intake in Q1, the Q2 2014 order intake is expected to show a strong double digit decrease as compared to Q1 2014, on a currency comparable base.
