Future Operation Policy and Investment Plan

The Company has endeavored to strengthen and expand its industrial motor business as one of its strategically important business areas, where Nidec Motor Corporation (formerly, Emerson Electric Co.’s motors and controls business, “NMC”), which the Company acquired in September 2010, has been the primary operating subsidiary.  Through the acquisition of Avtron, the Company seeks to strengthen the industrial motor and automation solutions businesses of NMC and Ansaldo Sistemi Industriali S.p.A. (“ASI”), which we acquired in May 2012, in North America, and accelerate the Company’s strategy to achieve synergies with the acquired companies.  In particular, Avtron’s rich system engineering resources and experience, together with the customer relationships Avtron has established, are expected to enhance the Company’s automation solutions capabilities in North America and contribute to the Company’s success in achieving business synergies with ASI.

Avtron is also expected to serve as a sales channel in North America for ASI’s drives, motors/generators, and automation systems.  With these products supplementing Avtron’s value-added industrial encoder products and drive system solutions and NMC’s motor products, the Company expects to be able to provide full-range of products and solutions services to Avtron’s core markets comprised of the energy, crane, metal, marine, and forest products industries in North America.
