The acquisition of Intersil is expected to (1) bolster the lineup of power management–related analog devices, key devices essential to future growth in our strategic focus domains, (2) enhance the ability to deliver to customers solutions such as kits combining Renesas microcontrollers (MCUs) and high-precision analog products from Intersil, (3) expand sales and design-ins outside of Japan, and (4) strengthen global management capabilities by welcoming Intersil’s management team with broad management expertise to Renesas Group. The acquisition is therefore seen as an effective measure to enhance Renesas’ competitiveness in fields where Renesas is focusing its efforts to boost sales and profits, and strengthening the company’s position as a global leader.

2. Acquisition Method

The acquisition will be implemented as follows. Renesas will establish for the purpose of the acquisition a wholly-owned subsidiary (“acquisition subsidiary”) in Delaware, United States that will then merge with Intersil (in a reverse triangular merger). The surviving company following the merger will be Intersil. Cash will be issued for Intersil’s shares as consideration for the merger, and the shares of the acquisition subsidiary owned by Renesas will be converted into outstanding shares in the surviving company, making the surviving company a wholly-owned subsidiary of Renesas. The acquisition will take effect following approval by Intersil shareholders and the relevant governmental authorities, and fulfilment of the other customary closing conditions pertaining to merger agreements. Under the merger agreement concluded between the parties for the purpose of implementing the acquisition, Renesas guarantees the fulfillment of obligations by the acquisition subsidiary.

For the purpose of the acquisition Intersil shares are to be acquired at a price of US$22.50 per share (for a total of approximately US$3,219 million (approximately ¥321.9 billion at an exchange rate of 100 yen to the dollar). Current cash reserves are expected to be sufficient to cover the purchase price, therefore Renesas has no plans to borrow new funds or issue new shares.
