About the USA group companies
The first Sumitomo Electric Group company in the US was established in 1971 in Los Angeles, California. Since then, the organization has grown steadily through the establishment of new subsidiaries and strategic acquisitions. Today, the US group companies collectively participate in all five of the Sumitomo Electric Group's major business segments: automotive, infocommunications, electronics, environment & energy, and industrial materials. Many products in each segment are made in the USA at manufacturing locations across the country. Thanks to successful relationships with many great customers, US group companies make a significant contribution to the net revenue of our parent company, Sumitomo Electric Industries, Ltd., a Fortune Global 500 company since 1994.
