Management Qualitative Comments

“This was another good quarter as we continued to see broad-based momentum across our customer base,” said Ron Jankov, president and CEO. “During the second quarter, revenue growth outside our largest customer grew by more than 30 percent, indicating a continuing strong demand for increasingly complex packet processing in a wide array of applications. Further, we received our first volume production orders for the NL8000 product family for shipment in the fourth quarter to our largest customer. This marks a company record for the speed in which we brought a product from tape out to fully-qualified volume production, and is the result of our success in achieving functionality and performance targets with first pass silicon. Our design-in activity continues to be very strong for both the NL7000 and NL8000 product families, where our advanced performance and unique functionality puts us in a position of custom, sole-sourced supplier for many complex applications. Our design engagements and design wins for our NETLite™ processors are increasing as we continue to work with our silicon partners to significantly upgrade the functionality of entry-level systems, such as broadband access and Ethernet switching. Also, our NETL7™ processor product family continues to expand with the release of the NLS1005 content processor featuring a high-speed PCI Express interface. We also announced the availability of production-ready software drivers, compilers and inspection engines for our NETL7 processors, which will allow us to effectively and efficiently support and engage with a much larger set of customers. We expect to announce design wins for our NETL7 processors with additional customers in the second half of 2007.”

• The company announced the availability of the NLS1005 content processor, the newest addition to its NETL7 Layer 7 knowledge-based processor family. The NLS1005 content processor features a high-speed PCI Express^® interface, and enables deep packet inspection and application signature recognition with 10-Gigabit line rate performance.

• The company announced the availability of production-ready software drivers, compilers and inspection engines for its NETL7 processors. This significantly reduces the amount of time and engineering resources required by the company and its customers to productize solutions incorporating the NETL7 processors.

• NetLogic Microsystems also announced initial revenue shipments of the NL8000, its fourth generation knowledge-based processor, to its leading customer in support of multiple programs covering a range of advanced products. The NL8000 knowledge-based processor features a number of major advances and industry firsts in knowledge-based processing. It achieves new levels of parallel processing performance through a patented dual-core technology and a first-of-its-kind ability to parse decisions into 64 unique processing elements, which is double the number of processing elements of any competitive part. This capability to execute multiple parallel decisions during a single core clock cycle combined with our highly pipelined synchronous cross-connect bussing scheme enables customers to deploy 100 Gbps ASIC, Switches, and Network Processors.

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, amortization of intangible assets, an in-process research and development charge and a fair value adjustment of the acquired inventory resulting from the acquisition of NSE assets of Cypress Semiconductor Corporation and the effects of our adoption of SFAS 123R upon the number of diluted shares used in calculating non-GAAP earnings per share.

We excluded stock-based compensation expense as well as amortization of intangibles as they are non-cash in nature. We excluded an in-process research and development charge and a fair value adjustment related to acquired inventory, as they are considered one-time expenses.

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 July 24, 2007 that the Company has submitted to the Securities and Exchange Commission.
