Management Qualitative Comments

“Our strong fourth quarter concluded what was another solid year for us,” said Ron Jankov, president and CEO.  “The diversification of our customer and revenue base underscored the success of our products in addressing the requirements of a number of emerging markets, as well as new opportunities within our current customer base.  As the network continues to rapidly evolve, knowledge-based processors are being designed into areas that have not utilized advanced search processing capabilities before.  Our engineering and operations teams, including those developing knowledge-based processors, advanced 10 Gigabit Ethernet PHYs and Layer 7 deep-packet inspection processors, all responded to these new opportunities with flawless execution in 2007 by developing and launching some of the most complex and sophisticated devices on the market today.  Their success in achieving stringent product requirements on first-pass silicon allowed us to accelerate our already aggressive product and technology roadmap.  As we enter 2008, we believe that our design win portfolio and competitive positioning is stronger than it has ever been.  We thank our investors and our customers for their support and look forward to sharing continued success in 2008.”

Recent Highlights

• NetLogic Microsystems announced the introduction of the NL9000 knowledge-based processor as part of the launch of its fifth-generation knowledge-based processor family.  The NL9000 processor is the industry’s first fully-programmable “hybrid” knowledge-based processor that features the convergence of high-performance, massively parallel knowledge-based processing with the superior low-power efficiency and flexibility of algorithmic Sahasra™ technology to dramatically reduce power consumption while delivering best-in-class performance and functionality for next-generation IPTV and advanced mobile wireless networks.
• During the fourth quarter, the company acquired Aeluros, Inc., a privately-held, fabless provider of industry-leading 10-Gigabit Interface technologies and semiconductor products.  Low-power, multi-gigabit interface technology is an increasingly important component in driving next-generation knowledge-based processors, as well as in enabling 10-Gigabit Ethernet (10GE) physical layer (PHY) connectivity for enterprise and datacenter networks.
• The company also introduced the NL8256 knowledge-based processor, which is targeted at mainstream applications and is the second device in its fourth-generation processor family.  This positions NetLogic Microsystems with twice the breadth of Gen-4 products relative to competing suppliers.
• NetLogic Microsystems and TSMC announced their collaboration on the industry-leading 55nm semiconductor process technology for NetLogic Microsystems’ advanced knowledge-based processors.  The use of TSMC’s 55nm process technology and state-of-the-art design techniques have allowed NetLogic Microsystems’ new 5 Generation knowledge-based processor to integrate a dramatic increase in functionality and performance in the smallest die size while using significantly less power than all previous designs.
• Deloitte & Touche ranked NetLogic Microsystems 4 on its prestigious Technology Fast 50 Program for Silicon Valley, a ranking of the fastest growing technology, media, telecommunications and life sciences companies in the region.  Also, Deloitte & Touche ranked NetLogic Microsystems 50 on its 2007 Technology Fast 500, a ranking of the 500 fastest growing technology, media, telecommunications and life sciences companies in North America.  NetLogic Microsystems was also ranked the third fastest growing semiconductor company on the list.

Non-GAAP Financial Information
In addition to disclosing financial results calculated in accordance with U.S. generally accepted accounting principles (GAAP), the Company’s earnings release contains non-GAAP financial measures that exclude the income statement effects of stock-based compensation, non-recurring items and other non-cash expenses discussed in the earnings release.  To derive non-GAAP operating income for the periods presented in the press release, the Company excluded all stock-based compensation expense for the periods as well as the impact of deferred tax asset valuation allowance release, the tax effect of an intercompany license agreement and certain charges related to acquired intangible assets and other acquisition-related charges from its acquisition of Aeluros, Inc. (the “Aeluros Acquisition”), the TCAM2 and TCAM2-CR network search engine products and certain related assets (the “TCAM2 Acquisition”) and the Network Search Engine Business (the “NSE Business Acquisition”) from Cypress Semiconductor Corporation , which closed on October 24, 2007, August 29, 2007 and February 15, 2006, respectively. Specifically, these non-GAAP financial measures reflect adjustments based on the following:

• Charges related to the Aeluros Acquisition: The Company incurred significant expenses in connection with the Aeluros Acquisition, which the Company would not have otherwise incurred, and which the Company believes are not indicative of the Company’s ongoing operating performance. Such acquisition-related charges primarily consisted of the amortization expense of acquired intangible assets, in-process research and development and the cost of fair value adjustment of acquired inventory.
  
  
• Charges related to the TCAM2 Acquisition: The Company incurred significant expenses in connection with the TCAM2 Acquisition, which it would not have otherwise incurred and which the Company believes are not indicative of the Company’s ongoing operating performance. Such acquisition-related charges primarily consisted of the amortization expense of acquired intangible assets and the cost of fair value adjustment of acquired inventory.
  
  
• Charges related to the NSE Business Acquisition: The Company incurred significant expenses in connection with the NSE Business Acquisition, which the Company would not have otherwise incurred, and which the Company believes are not indicative of the Company’s ongoing operating performance. Such acquisition-related charges primarily consisted of the amortization expense of acquired intangible assets, in-process research and development and the cost of fair value adjustment of acquired inventory.

We use the non-GAAP financial measures that exclude these items to make strategic decisions, forecast future results and evaluate the Company’s current performance. We believe that the presentation of non-GAAP financial measures that exclude these items is useful to investors because we do not consider these charges part of the day-to-day business or reflective of the core operational activities of the Company that are within the control of management or that would be used to evaluate management’s operating performance.

The non-GAAP financial measures disclosed by the Company should not be considered a substitute for, or superior to, financial measures calculated in accordance with GAAP, and the financial results calculated in accordance with GAAP and reconciliations to those financial statements should be carefully evaluated. The non-GAAP financial measures used by the Company may be calculated differently from, and therefore may not be comparable to, similarly titled measures used by other companies.  The Company has provided reconciliations of the non-GAAP financial measures to the most directly comparable GAAP financial measures.  For additional information regarding these non-GAAP financial measures, and management’s explanation of why it considers such measures to be useful,  refer to the Form 8-K dated January 29, 2008 that the Company has submitted to  the Securities and Exchange Commission.
