(Nasdaq:PMCS), a leading provider of high-speed broadband communications and storage semiconductors, today reported results for the third quarter ending September 30th, 2007. Net revenues in the third quarter of 2007 were $117.5 million compared with $104.7 million in the second quarter of 2007, and $116.5 million in the third quarter of the prior year. Net loss in the third quarter of 2007 on a GAAP basis was $5.9 million (GAAP diluted loss per share of $0.03) compared with GAAP net loss of $22.3 million (GAAP diluted loss per share of $0.10) in the second quarter of 2007. Non-GAAP net income in the third quarter of 2007 was $19.1 million (non-GAAP diluted earnings per share of $0.09) compared with a non-GAAP net income in the second quarter of 2007 of $7.4 million (non-GAAP diluted earnings per share of $0.03). "In the third quarter, we experienced strong growth in our telecom business, particularly in Asia, as well as positive trends in our enterprise storage business," said Bob Bailey, chairman and chief executive officer of PMC-Sierra. "Our summer bookings were strong, and our operating performance increased in the quarter as a result of the combination of top-line growth and expense reductions." Non-GAAP net income in the third quarter of 2007 excludes the following items: (i) $8.1 million in stock-based compensation expense; (ii) $9.8 million in amortization of purchased intangible assets; (iii) $1.6 million in costs and charges related to the Company's corporate restructuring announced March 29, 2007; (iv) $6.8 million foreign exchange loss on foreign denominated FIN 48 tax liabilities; and (v) $1.2 million income tax effect relating to these non-GAAP adjustments. For a full reconciliation of GAAP net income to non-GAAP net income, please refer to the schedule on page 6 of this release. The Company believes the additional non-GAAP measures provided are useful to investors for the purpose of financial analysis. Management uses the non-GAAP measures internally to evaluate its operating performance before gains, losses and other charges that are considered by management to be outside of the Company's core operating results, as well as used to plan for the Company's future periods. Non-GAAP measures are however neither stated in accordance with, nor are they a substitute for, GAAP measures.

A non-GAAP financial measure is a numerical measure of a company's performance, financial position, or cash flows that either excludes or includes amounts that are not normally excluded or included in the most directly comparable measure calculated and presented in accordance with GAAP. The Company believes that the additional non-GAAP measures are useful to investors for the purpose of financial analysis. Management uses these measures internally to evaluate the Company's in-period operating performance before gains, losses and other charges that are considered by management to be outside of the Company's core operating results. In addition, the measures are used for planning and forecasting of the Company's future periods. However, non-GAAP measures are not in accordance with, nor are they a substitute for, GAAP measures. Other companies may use different non-GAAP measures and presentation of results. PMC-Sierra, Inc.
