SDK and HOYA to Consolidate HD Media Operations

Tokyo, Sept 30, 2008 - (JCN Newswire) - Showa Denko K.K. (SDK) and Hoya Corporation (HOYA) have reached basic agreement to consolidate their hard disk (HD) media operations by establishing a joint venture in January 2009. The joint venture, to be owned about 75% by SDK and about 25% by HOYA, will manage the consolidated operations. SDK and HOYA will announce other details of the joint venture as soon as they are worked out.

SDK will contribute its aluminum- and glass-based HD media and aluminum substrate operations and HOYA its glass-based HD media operations. The joint venture will perform R&D, production, marketing, sale and customer support functions to serve the world HD media market, and will have annual sales of around 180 billion yen. HOYA will continue its glass substrate operation on its own.

The HD market is expected to continue growing at high rates, centering on notebook PCs and digital electric appliances. Storage capacity of HD media will also continue to increase substantially. Thus, independent HD media suppliers need to promote R&D of next- generation magnetic recording technologies and to speedily provide next-generation products to hard disk drive manufacturers.

Under the circumstances, SDK and HOYA decided to combine their respective strengths and increase operational efficiency as a means to further expand their operations in the changing environment. Specifically, the two companies aim to develop new HD media products with higher storage capacity through concerted efforts and to increase the efficiency of their operation sites in Japan and overseas (totaling five).

Through these efforts, SDK and HOYA will aim to meet customer expectations by speedily launching advanced products and ensuring timely and efficient production. At the same time, SDK and HOYA will aim to ensure sound growth of their HD media business and strengthen competitiveness in a sustainable manner.
