Results of Operations and Financial Condition On January 25, 2006, PMC-Sierra, Inc. (the "Registrant") issued a press release reporting the financial results for its fiscal fourth quarter and fiscal year ended December 31, 2005. The press release is attached hereto as Exhibit 99.1 and incorporated by reference herein. The information in this Form 8-K and the Exhibit, attached hereto, shall not be deemed to be "filed" for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), or otherwise subject to the liabilities of that section, nor shall it be deemed incorporated by reference in any filing under the Securities Act of 1933, as amended, or the Exchange Act, regardless of any general incorporation language in such filing. As a supplement to the Registrant's consolidated financial statements presented on a generally accepted accounting principles (GAAP) basis, the Registrant provides additional non-GAAP measures for net income and net income per share in its press release. 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 Registrant believes that the additional non-GAAP measures are useful to investors for the performance of financial analysis. Management uses these measures internally to evaluate its in-period operating performance and the measures are used for planning and forecasting of the Registrant'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. ITEM 9.01.
