Meyer Burger Technology Ltd and subsidiaries, respectively have acquired a further participation of 6.34% of the share capital of Roth & Rau AG through a share purchase and share exchange contract at a price of EUR 22 per non-par value bearer share on 20 April 2011. With this transaction, the previous major shareholder OTB Group B.V., NL-Eindhoven has sold its entire participation in Roth & Rau AG to Meyer Burger Technology Ltd and supports the strategic consolidation of both companies. In conjunction with the contract, Meyer Burger issued 245,506 new registered shares out of its authorised share capital. The first trading day of these shares at SIX Swiss Exchange is expected to be 26 April 2011.

With the purchase of this block of shares, Meyer Burger Technology Ltd currently holds a total participation of 17.7% (including 3.9% under the condition precedent of clearance by antitrust authorities) in Roth & Rau AG.

On April 11, 2011, Meyer Burger publicly announced the launch of a voluntary public takeover offer to acquire all remaining non-par value bearer shares of Roth & Rau AG held by public shareholders at a price of EUR 22 per share in cash. The offer price corresponds to a premium of 40% (date source: calculation of average share price by German Federal Financial Supervisory Authority) compared with the volume weighted average share price of the last three months prior to the announcement of the transaction. The Executive Board and the Board of Directors of Roth & Rau support the offer by Meyer Burger.

Meyer Burger Group will strengthen its offerings in the solar cell process through the planned consolidation of both companies and combines the most important technology steps within the value chain of photovoltaics, mainly in the production processes of wafering, solar cells and solar modules.
