Meyer Burger Technology Ltd (and through subsidiaries, respectively) has acquired a total participation of 7.4% of the share capital of Roth & Rau AG through share purchase and share exchange contracts immediately and 3.9% under the condition precedent of clearance by antitrust authorities from the founders and key shareholders Dr. Dietmar Roth (Chief Executive Officer), Prof Dr. Silvia Roth and from Dr. Bernd Rau on 10 April 2011. In conjunction with these contracts, Meyer Burger issued 840’802 new registered shares out of its authorized share capital. The first trading day of these shares at SIX Swiss Exchange is expected to be 13 April 2011.

Meyer Burger will also launch 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 41.5% compared with the volume weighted average share price of the last three months^[1]. The Executive Board and the Board of Directors of Roth & Rau support the offer by Meyer Burger.

Meyer Burger Group is one of the world’s leading providers of innovative systems and production lines for photovoltaics in the solar industry, and for the semiconductor and optics industries (LED), with over 1,200 employees and net sales of CHF 826 million in fiscal year 2010. The group already covers the most important technology processes along the entire value chain of photovoltaics (solar industry) with a focus on solar wafering and solar modules.

Roth & Rau Group is one of the world’s leading suppliers of production equipment and innovative production technologies for the manufacture of solar cells with a strong focus on antireflective coating systems for crystalline silicon solar cells. The company has production sites in Hohenstein-Ernstthal and Eindhoven and employed over 1,200 people at year-end of 2010. Roth & Rau generated net sales of EUR 285 million in fiscal year 2010.

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 from crystalline silicon to complete solar systems, mainly in the production processes of wafering, solar cells and solar modules.

Peter Pauli, Chief Executive Officer of Meyer Burger Technology Ltd, comments, “With Roth & Rau Group, we further enhance our industry solutions for photovoltaics. With joint activities in research & development, the combination of our distribution networks and through the larger offering of fully integrated system solutions we play a crucial role in further reducing the costs along the value chain in photovoltaics. This is just another step to sustainably reduce the costs of solar power and to help achieving the industry goal of grid parity as fast as possible.”

Dr. Dietmar Roth, Chief Executive Officer of Roth & Rau AG, “We are convinced that Meyer Burger is the ideal strategic partner for a continuous dynamic development of our Group. Shareholders, our employees, suppliers and customers as well as the entire solar industry will profit from the new combined group.”

Meyer Burger will finance the voluntary public takeover offer from its existing cash position and through a syndicated bank loan.

The offer is subject to usual conditions for such transactions, in particular receipt of regulatory clearances from different antitrust authorities. The offer document will be submitted to the German Federal Financial Supervisory Authority (FFSA) within the upcoming four weeks and will be published following the receipt of the permission by the FFSA. The closing of the transaction is expected towards the third quarter of 2011.
