• Operating result decreased to €28 million compared to the previous quarter. The decrease is mainly the result of the lower sales level.

COMMENT

Commenting on the results, Chuck del Prado, President and Chief Executive Officer of ASM International said:
"In Q3 we realized sales of €196 million and an order intake of €258 million. Sales were within our guidance of €180-200 million while order intake was well above the € 200-230 million that we earlier indicated and was 25% above our former highest level. The high order intake is driven by logic, foundry and analog. The gross margin in Q3 remained in the range of low to mid 40's. During the third quarter we returned approximately €380m to our shareholders in the form of share buybacks and a tax efficient capital return."

OUTLOOK

For Q4, on a currency comparable level, we expect sales of €220-250 million and an order intake of € 240-260 million. Q4 still reflects some uncertainty around the exact timing of individual tools.

For 2018, general expectations for growth of the wafer fab equipment market remain at mid to high single digits. Based upon this current market development 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 new share buyback program of its common shares for an amount of up to €250 million. On September 30, 2018, 83.7% of the program was repurchased. We completed this 2018 share buyback program on October 11, 2018. In total, we repurchased 5,443,888 shares at an average price of €45.92, including expenses, under the 2018 program.

This share buyback program was executed by a third party. ASMI has the intention to reduce its issued share capital by withdrawing the shares repurchased as part of the 2018 share buyback program, save for such number of treasury shares as maybe necessary to fund ongoing share and option programs for employees and board members. This withdrawal of shares is intended to be proposed to the Annual General Meeting (AGM) in 2019. The repurchase program is part of ASMI's commitment to use excess cash for the benefit of its shareholders.

On August 10, 2018, ASMI distributed €4.00 per common share to its shareholders through a tax efficient repayment of capital. The ex-date of the distribution was August 7, 2018. This capital repayment was previously approved by the 2018 AGM.

On August 1, 2018, the withdrawal of 6 million treasury shares, which was previously approved by the 2018 AGM, became effective and administered. Following this withdrawal the total number of issued shares decreased to 56,297,394 as per August 1, 2018.
