Merger and reorganization of businesses of power transmission/distribution electric wires/cables and electrical equipment

On January 1, 2016, the power transmission/distribution wire/cable business and electrical equipment businesses operated by Sumitomo Electric, J-Power Systems Corporation (JPS), and Sumiden Asahi Industries, Ltd. (Sumiden Asahi) will be merged and reorganized as described below.

1. Reorganization of the power transmission/distribution wire/cable business

JPS’s business related to design, development, and quality assurance of electric wires, cables, and power transmission equipment will be transferred to Sumitomo Electric through an absorption-type company split, and will be consolidated under Sumitomo Electric’s brand.

JPS will focus primarily on manufacture of power transmission/distribution wires/cables.

The sales and installation operations of electric wires, cables, and power transmission equipment have been transferred to Sumitomo Electric on August 1, 2014.

2. Reorganization of the electrical equipment business

JPS’s business related to (i) design, development, manufacture, raw materials procurement, and quality assurance of aerial equipment and power distribution equipment and (ii) manufacture and raw materials procurement of power transmission equipment will be merged by Sumiden Asahi through an absorption type company split. Sumiden Asahi’s name will be changed (new company after merger: Sumiden Transmission and Distribution Systems Products Corp. [tentative name]).

The sales operations regarding electrical equipment for power companies will be undertaken solely by Sumitomo Electric. Products will be sold under the Sumitomo Electric brand.

The products for private companies currently sold by Sumiden Asahi will be sold by the new company after merger.

In these power businesses, the demand for electricity is expected to grow in emerging countries in Asia, etc. Offshore wind power generation and international interconnection line projects, among others, are also expected to boost the demand. Meanwhile, the demand in Japan remains sluggish, resulting in a difficult business environment. Based on this reorganization, we will further advance our efforts to develop products and expand the business while properly identifying business opportunities, in order to offer ever higher value to customers within and outside Japan.
