Almere, The Netherlands
November 2, 2017
ASM International N.V. (Euronext Amsterdam: ASM) ("ASMI") today announces that it intends to sell a stake of 37 million shares of the total outstanding share capital in ASM Pacific Technology Ltd. ("ASMPT") through a partial secondary share placement. ASMI intends to distribute a part of the proceeds to its shareholders in the form of a tax efficient capital return.

ASMI is proposing a reduction of its stake in ASMPT through an accelerated bookbuild offering to institutional investors of 37 million shares representing a stake of approximately 9% in ASMPT which is launching now. Following the planned divestment ASMI will own approximately 25% of the shares in ASMPT.

ASMI intends to distribute a part of the proceeds to its shareholders in the form of a tax efficient capital return. A proposal thereto will be placed on the agenda of the 2018 AGM. ASMI remains committed to use excess cash for the benefit of its shareholders.

With the sale of a 9% stake in ASMPT the Management Board aims to take an important further step in creating long term value for our company next to our continuous efforts in strengthening our Front-end operations. The Management Board remains of the opinion that, at this moment, a significant stake in ASMPT is of strategic value to ASMI. With a remaining stake of approximately 25% in ASMPT the Management Board believes that this strategic value is still maintained.

Morgan Stanley & Co. International plc is acting as bookrunner for this transaction.

Once the outcome of the offering has been established, ASMI will make a further public announcement. ASMI has agreed to a 180 day lock-up period, subject to usual terms and conditions.
