Hitachi, Mitsubishi Electric and Mitsubishi Heavy Industries

Tokyo, August 4, 2011 - As previously announced on March 30, 2011, Hitachi, Ltd. (NYSE: HIT / TSE: 6501, "Hitachi"), Mitsubishi Electric Corporation (TSE: 6503, "Mitsubishi Electric") and Mitsubishi Heavy Industries, Ltd. (TSE: 7011, "MHI") entered into a basic agreement calling for the three companies to consolidate their hydroelectric power generation system operations by way of simplified absorption-type company splits of their respective operations and the transfer of those operations to HM Hydro, Ltd. ("HM Hydro"), a Hitachi subsidiary. Effective today, the three companies have formally decided to authorize their respective splits. Because the resulting declines in gross assets at the three companies correspond in each case to less than 10% of the company's net assets as of the close of the most recent fiscal year, and because the resulting declines in sales at each of the three companies are projected in each case to correspond to less than 3% of the company's net sales in the most recent fiscal year, some items and contents of disclosure have been omitted from this notification.
