      net income per share is calculated by dividing non-GAAP net income by

      and not yet recognized in the financial statements. Under the GAAP
      treasury stock method, these stock-based compensation costs are treated as

Results
      of Operations and Financial
Condition.
The
information contained in this report and the exhibit attached hereto is
furnished solely pursuant to Item 2.02 of Form 8-K and shall not be deemed
"filed" for purposes of Section 18 of the Securities Exchange Act of 1934,
as amended, or otherwise subject to the liabilities of that section. The
information contained herein and the exhibit attached hereto shall not be
incorporated by reference into any filing with the Securities and Exchange
Commission made by NetLogic Microsystems, Inc., whether made before or after the
date hereof, except as shall be expressly set forth by specific reference in
such filing.
On
February 3, 2009, we issued a press release announcing our financial results for
the three and twelve months ended December 31, 2008, which is included in this
report as Exhibit 99.1. The press release should be read in conjunction with the
statements regarding forward-looking statements that are included in the text of
the press release.
Discussion
of Non-GAAP Financial Measures
In
addition to disclosing financial results calculated in accordance with U.S.
generally accepted accounting principles (GAAP), the Company also reports
certain non-GAAP financial measures.  Non-GAAP financial measures
exclude the effects of stock-based compensation, amortization of acquired
intangible assets, fair value adjustments of acquired inventory, in-process
research and development charges, the impact of a deferred tax asset valuation
allowance release, the tax effect of an intercompany license agreement and the
effects of excluding stock-based compensation on the number of diluted shares
used in calculating non-GAAP earnings per share.
Non-GAAP
financial measures should be considered in addition to, and not as a substitute
for, the results prepared in accordance with GAAP, and the financial results
calculated in accordance with GAAP and reconciliations to these non-GAAP
measures should be carefully evaluated.  The non-GAAP financial
measures we use may be calculated differently from, and therefore may not be
fully comparable to similarly titled measures used by other
companies.  We believe the non-GAAP information is useful because it
can enhance the understanding of our ongoing economic performance and therefore,
we use non-GAAP reporting internally to evaluate and manage our
operations.  We have chosen to provide this information to investors
to enable them to perform comparisons of operating results in a manner similar
to how we analyze our operating results internally.  We also believe
that these non-GAAP financial measures may be used to facilitate comparisons of
our results with that of other companies in our industry and that investors may
find our non-GAAP net income information useful in their assessment of our
operating performance and the valuation of our company.
Non-GAAP
net income reflects net income adjusted for the following items:
•
Stock-based compensation.
Stock-based compensation relates primarily to employee stock
      options and restricted stock units and awards.  Stock-based
      compensation expense is a non-cash expense that is difficult to predict as
      its valuation is affected by changes in market forces, such as our common
      stock price and its volatility, which is not within the control of
      management.  Accordingly, we exclude this item from our internal
      operating forecasts and models.
•
Amortization of intangible
      assets.
Purchased intangible assets relate primarily to
      core and developed technology and customer relationships of acquired
      businesses.  We consider these charges non-cash in nature and
      unrelated to our core operating
performance.
•
Fair value adjustments of
      acquired inventory.
We consider these charges non-cash
      in nature and unrelated to our core operating
  performance.
•
In-process research and
      development charge.
We consider these charges non-cash
      in nature and unrelated to our core operating
  performance.
•
D
eferred tax asset valuation
      allowance release.
We consider these charges non-cash in
      nature and unrelated to our core operating
  performance.
•
Tax effect of intercompany
      license agreement.
We consider these charges non-cash in
      nature and unrelated to our core operating
  performance.
The
calculation of non-GAAP net income per share is adjusted for the following
item:
•
Non-GAAP
      net income per share is calculated by dividing non-GAAP net income by
      non-GAAP diluted weighted average shares. For purposes of calculating
      non-GAAP net income per share, the GAAP anti-dilutive weighted average
      shares outstanding is included after adjustments to exclude the
      benefits of stock-based compensation costs attributable to future services
      and not yet recognized in the financial statements. Under the GAAP
      treasury stock method, these stock-based compensation costs are treated as
      proceeds assumed to be used to repurchase shares. Since our non-GAAP net
      income does not reflect the effects of stock-based compensation costs,
      management believes these amounts should not be applied to the repurchase
      of shares in calculating non-GAAP net income per
  share.
We expect
to continue to incur expenses similar to the non-GAAP adjustments described
above, and exclusion of these items from our non-GAAP financial measures should
not be construed as an inference that these costs are unusual, infrequent or
non-recurring.  Some of the limitations in relying on non-GAAP
financial measures are:
•
Non-GAAP
      financial measures do not account for stock-based compensation expense
      related to equity awards granted to our employees. Our stock incentive
      plans are an important component of our employee incentive compensation
      arrangements and are reflected as expense in our GAAP
    results.
•
While
      amortization of purchased intangible assets does not directly affect our
      current cash position, such expenses represent the declining value of
      technology and other intangible assets we have acquired over their
      respective expected economic lives. The expense associated with this
      decline in value is excluded from non-GAAP financial measures, and
      therefore the non-GAAP financial measures do not reflect the costs of
      acquired intangible assets that supplement our research and development
      efforts.
