Topsil to extend current long term float zone wafer agreement with customer throughout 2017

Topsil and one of its major customers today signed an agreement for a two-year extension of the current long term agreement on sales of float zone wafers until and including 2017.

In order to further build upon their good cooperation, Topsil and its customer have concluded an agreement which amongst others entails that the customer will meet its agreed purchase commitment which it has not been capable of meeting throughout the original contract period due to the current state of the market. As part of the agreement, the customer will contribute to cover the cash related effect of the extension.

The agreement will not have any impact on the expectations for 2014.

Any queries regarding this stock exchange announcement may be addressed to the company's CEO through Christina Fris Bjørling, Communications Manager, tel.: +45 2152 1011.

Med venlig hilsen/ Best regards

Topsil Semiconductor Materials A/S
