"In 2005, PMC's revenues improved each quarter and our storage business experienced the fastest growth during the year as 4G Fibre Channel devices entered into production," said Bob Bailey, chairman and chief executive officer of PMC-Sierra. "We are well-positioned for 2006 in both wireline and wireless infrastructure as well as the enterprise storage market with the acquisition of the storage semiconductor division of Agilent Technologies which is expected to close in the first quarter of 2006." In the fourth quarter of 2005, PMC-Sierra announced it had entered into a definitive agreement with Kohlberg Kravis Roberts & Co. and Silver Lake Partners to acquire the storage semiconductor business of Agilent Technologies for approximately $425 million in cash. The storage semiconductor business is part of Agilent's Semiconductor Products Group, which KKR and Silver Lake Partners acquired in December 2005. The acquisition, which at this time is expected to close in the first quarter of 2006, will significantly strengthen PMC-Sierra's position as a leading provider of silicon solutions to the enterprise storage market. In the fourth quarter, PMC-Sierra issued $225 million aggregate principal amount of senior convertible notes due 2025. The notes bear interest at a rate of 2.25% per year and under certain circumstances may be convertible into cash (up to the principal amount of the notes) and, with respect to any excess conversion value, into cash, shares of common stock of PMC-Sierra or a combination of cash and shares of common stock, at the company's option.
