Press Release SMA Solar Technology AG Founders of SMA Solar Technology AG establish charitable trusts Niestetal, May 10, 2011 – Founders and major shareholders of SMA Solar Technology AG (SMA/FWB: S92), Günther Cramer, Peter Drews and Reiner Wettlaufer, have each placed a portion of their shares in a non-profit trust. The trusts benefit a joint trust association for project development and are intended to develop and advocate concepts and business models for distributing regenerative energy supply systems in addition to commercial, scientific, cultural and social regional development. At the same time, the sponsors created a significant prerequisite for further independence of SMA by establishing the trusts. Founders and major shareholders of SMA Günther Cramer, Peter Drews and Reiner Wettlaufer have announced the establishment of three independent charitable trusts vested with legal capacity. The trusts were approved by the Regional Administrative Authority Kassel and acknowledged as nonprofit by the tax office Kassel. Each sponsor brought two million shares of SMA and additional liquid funds as financial resources into his trust. This equals about 45 percent of of SMA shares still held by the sponsors. This means that the dividend distribution of these shares following the Annual General Meeting on May 26, 2011 will flow into the trusts with a major part of the dividend contributing to the trusts’ assets. Since the three independent trusts have the same general missions, the sponsors intend to carry out a major part of realising the purpose by means of joint projects. A trust association is to be established as a non-profit GmbH to look after the trusts’ project development responsibility and is expectedto start work in autumn 2011. The trust association will be based in Kassel. The trusts' purpose includes developing and advocating regenerative energy supply systems and concepts, as well as business models for their distribution. In particular, this applies to regions in developing countries that have insufficient connections to the public power supply system. In addition, the trusts have the goal to advocate commercial, scientific, cultural and social regional development in North Hesse in particular and to realise charitable missions. The trusts‘ SMA share assets are to be maintained in their respective portfolios. By establishing the trusts, the sponsors ensure that SMA will continue to have a very stable shareholder structure, therefore being largely independent in the future as well.
