Frederikssund, 20.04.2016 Announcement No. 3/2016

In connection with the strategy review carried out in 2015, Topsil analysed market developments, its market position and its future opportunities. During this process, we approached other players in the silicon industry and different parts of our value chain.

In continuation of these soundings, Topsil has been approached by various parties concerning our possible interest in divesting parts or all of our silicon business or in entering into a strategic partnership. Some of these inquiries are in the form of non-binding indicative offers.

The Board of Directors will now assess whether these inquiries are of interest to Topsil and all of our stakeholders, or whether there may be other, more attractive strategic alternatives.

Further information will be provided as required or when deemed appropriate, and the Board of Directors will make a specific recommendation to the shareholders if relevant.
