Mitsui Chemicals Purchases 50.01% Share of DENTCA, Inc.

Mitsui Chemicals, Inc., to further expand its dental material business, acquired 50.01% of issued and outstanding shares of DENTCA, Inc. ("DENTCA") on June 20, 2013. DENTCA, with its head office in the United States, develops, manufactures, and distributes dentures using new cutting edge computer-aided design (CAD), computer aided manufacturing (CAM) technology, and proprietary 3-Dimensional modeling and printing technology.

"Mitsui Chemicals, in line with one of its strategies in the FY2011 Mid-term Business Plan, has expanded its portfolio in businesses resilient to changing economic conditions such as healthcare," stated Minoru Koshibe, Mitsui Chemicals Executive Vice President. "As part of this strategy, Mitsui Chemicals targets active expansion including M&As, such as this April's acquisition of the dental materials business of German Heraeus Holdings GmbH, which has a global manufacturing and sales network."

The dentures market is expected to continue to grow leveraged by the increase in aging of world-wide populations and rising incomes in emerging countries.

"We are pleased to become a partner of a well respected company like Mitsui Chemicals,"says Tae Hyung Kim, DENTCA President. "DENTCA and Mitsui Chemicals share a common philosophy that is, improving human life with innovative products."

Mitsui Chemicals targets expansion of its global denture business through DENTCA's cutting-edge denture design technology using CAD/CAM and its own advanced material development and processing technology to develop high-performance dentures that meet global needs. In addition, both parties will benefit from the synergistic effect brought by the abundant selection of dental-related materials of Heraeus Dental.
