ITEM 2.02.   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.
