Pioneer Completes Acquisition of NEC Plasma Display Corporation

TOKYO — Pioneer Corporation today announced that it had on September 30, 2004 completed acquisition of all the shares in NEC Plasma Display Corporation (NPD), a subsidiary of NEC Corporation, pursuant to the stock transfer agreement concluded on July 1, 2004. NPD changed its name to “Pioneer Plasma Display Corporation” as of September 30, 2004. Matters pertaining to the acquisition are as follows:
