COMMENT

Commenting on the results, Chuck del Prado, President and Chief Executive Officer of ASM International said:

"In Q2 we realized sales of €209 million and an order intake of €176 million. Both sales and order intake were within our guidance, despite the uncertainty around the exact timing of individual tools as mentioned in the Q1 earnings release. The gross margin in Q2 at 42% returned back again in the range of low to mid 40's. This month at Semicon West, we introduced the Synergis, the latest addition to ASM's industry-leading line of ALD tools, which addresses a wide range of advanced applications and will drive expansion of our Served Available Market within single-wafer ALD."

OUTLOOK

For Q3, on a currency comparable level, we expect sales of €180-200 million and an order intake of € 200-230 million. Q3 reflects still some uncertainty around the exact timing of individual tools.

For 2018, general expectations for growth of the wafer fab equipment market are currently mid to high single digits. Based upon the current market developments we expect our sales in the second half to be stronger than in the first half. We expect to outgrow the wafer fab equipment market in 2018.

  

SHARE BUYBACK PROGRAM AND CAPITAL REPAYMENT

On June 5, 2018, ASMI announced the start of a share buyback program of ASMI's common shares up to €250 million. This program follows on ASMI's announcement on February 28, 2018, that it intended to use €250 million of the proceeds of the partial sale of a stake of approximately 9% in ASMPT for a new share buyback program. The repurchase program is part of ASMI's commitment to use excess cash for the benefit of its shareholders. On June 30, 2018, 16.6% of the program was completed at an average share price of €51.20.

On May 28, 2018, the 2018 Annual General Meeting of Shareholders (AGM), approved the proposal to distribute €4.00 per common share through a tax efficient repayment of capital. Following a statutory period under Dutch law of two months for opposition by creditors, the indicative ex-date for the distribution of €4.00 per common share is August 7, 2018, and the indicative payment date is August 10, 2018.

The 2018 AGM also approved the proposed withdrawal of 6 million treasury shares which is expected to become effective and administered on August 1, 2018, subject to the finalization of the mandatory legal procedures.
