Management Qualitative Comments

“2009 was truly a transformative year for the company,” said Ron Jankov, president and CEO.  “Outstanding engineering achievement in our knowledge-based processor and physical layer solutions allowed us to achieve record numbers of design wins, unprecedented competitive positioning and a further extension of our technology leadership.  In addition, 2009 marked a major step in the company’s growth with our successful merger with RMI Corporation, a technology leader and true innovator in the rapidly emerging high-end multi-core processor market and the ultra-low power embedded processor market.   The integration of our companies is proceeding very smoothly and we are excited about the opportunities that the merger has presented for us to integrate our best-in-class physical layer products, knowledge-based processors and multi-core processors into highly-advanced platform-level solutions.  This capability is a significant competitive advantage and will further strengthen our customers’ ability to develop next-generation equipment to support the expected exponential growth in converged IP traffic.”

 

Recent Highlights

• The company announced the NL11K processor, the world’s first knowledge-based processor with high-speed serial interface, and a member of its sixth-generation knowledge-based processor family.  The integration of high-speed serial interface delivers 225Gbps of raw chip-to-chip interconnect bandwidth.  This represents a 340 percent increase in I/O bandwidth-per-pin to enable significantly higher system performance, higher system density and lower system costs for next-generation systems to enable significantly richer services for LTE, IPTV and IPv6 services.  In addition, the NL11K processor features an enhanced knowledge-based processing core capable of achieving 1.6 billion decisions per second.

• NetLogic Microsystems was awarded its 400th United States patent. Its portfolio includes over 600 worldwide patent issuances and pending filings. These achievements mark a significant milestone in the company's history of being at the forefront of technological and innovation leadership in high-performance semiconductor solutions that perform highly differentiated tasks for advanced 3G/4G mobile wireless infrastructure, data center, enterprise, metro Ethernet, edge and core infrastructure networks.

• The company took part in the Consumer Electronics Show 2010, demonstrating several new products in its Alchemy® family of ultra low-power embedded processors.  The company also announced that it was recently awarded several design wins with leading customers, including Samsung Electronics, SHARP Electronics and Tinnos.

• The company received the "Most Respected Emerging Public Semiconductor Company Award" for 2009 from the Global Semiconductor Alliance (GSA). This prestigious award recognized NetLogic Microsystems for its vision, strategy, leadership and success in the semiconductor industry among its peers of public semiconductor companies with annual revenues of up to $500 million.

• The company continues to expand its physical layer product portfolio and recently announced production availability of its new NLP1220 dual-port FibreChannel PHY device. This device offers best-in-class power consumption and latency to customers developing next-generation data center switches and connected storage devices. It was selected by Fujitsu Technology Solutions during the fourth quarter for Fujitsu’s next-generation data center blade solutions.

• The company’s Au1300® processor, the latest member of its ultra low-power Alchemy processor family, has been selected by LG Electronics for LG’s high-performance automotive infotainment solutions. LG’s market-leading infotainment solutions include built-in audio/video navigation (AVN) for dashboard and rear-seat entertainment (RSE) systems.

• NetLogic Microsystems completed its merger with RMI Corporation, a leading provider of high-performance and low-power multi-core, multi-threaded processors. The merger enables NetLogic Microsystems to further expand into the high-performance "data-in-flight" processing market. RMI's cutting-edge XLPTM, XLR® and XLS® Multi-Core, Multi-Threaded Processors will complement NetLogic Microsystems' existing portfolio of knowledge-based processors, content processors, network search engines and 10-100 Gigabit Ethernet PHY products.

Non-GAAP Financial Information

In addition to disclosing financial results calculated in accordance with U.S. generally accepted accounting principles (GAAP), this announcement of operating results contains non-GAAP financial measures that exclude the income statement effects of stock-based compensation and related payroll taxes, changes in contingent earn-out liability, amortization of intangible assets, fair value adjustments of acquired inventory, acquisition-related costs, interest income on a bridge loan to RMI Corporation, debt issuance cost write-off, deferred tax asset valuation allowance on a portion of the Company’s California research and development credit carryforward, the tax effect of inventory fair value adjustments and adjustment charges related to certain tax reserves relating to an intercompany license agreement, and the effects of excluding stock-based compensation upon the number of diluted shares used in calculating non-GAAP earnings per share.

We have excluded stock-based compensation expense and changes in contingent earn-out liability in calculating these non-GAAP financial measures.  These expenses are non-cash in nature and rely on valuations based on future events such as the market price of our common stock and revenue generated from products acquired in the RMI acquisition during the first 12 months following the close that are difficult to predict and are affected by market factors that are largely not within the control of management. We have excluded amortization of intangibles, fair value adjustments related to acquired inventory, acquisition-related costs, interest income on RMI bridge note, debt issuance cost write-off, deferred tax asset valuation allowance on a portion of the Company’s California research and development credit carryforward, tax effect of inventory fair value adjustments, adjustment charges related to certain tax reserves relating to an intercompany license agreement because we do not consider them to be related to our core operating performance.

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 either 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 are 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 February 2, 2010 that the Company has submitted to the Securities and Exchange Commission.
