NASDAQ OMX Copenhagen A/S 19 May 2010 Nikolaj Plads 6 DK - 1067 Copenhagen K No. 18/10 Topsil Semiconductor Materials A/S has completed fully subscribed offering of shares with preemptive rights, resulting in gross proceeds of DKK 93.5m Topsil Semiconductor Materials A/S (”Topsil” or ”The Company”) announces that the company's offering of 103,890,151 new shares at a price of DKK 0.90 per share with preemptive rights for existing shareholders, has been successfully subscribed. As is customary in share issues, a minor number of the offered shares (0.52%) were not subscribed, and hence they were subscribed by institutional investors and Topsil's principal bank. The offering amounts to gross proceeds of DKK 93.5m. After deduction of costs related to the offering, net proceeds amount to approximately DKK 87.0m at Topsil's disposal. The proceeds, as well as the expected cashflows from operations, will be used for implementing an offensive growth strategy and expand production capacity. "We are pleased with the progress of the offering which was practically fully subscribed. The outcome shows us that the market has confidence in Topsil and the growth plans behind our offering. Our next concrete step is the planning of our new production facilities and investments in new production equipment, which will make it possible to meet the expected growth development for the coming years" says Chairman of Topsil, Mr. Jens Borelli-Kjær. The new shares will have the same rights as Topsil's existing shares and carry the right of dividend as of the financial year 2010. The capital increase is expected to be registered at The Danish Commerce and Companies Agency (DCCA) 20 May 2010.
