AnalogicTech Reports Financial Results for the First Quarter 2007

Company Reports First Quarter Revenue of $21.1 Million, Up 15% Year-Over-Year

Sunnyvale, CA – April 26, 2007 – Advanced Analogic Technologies Incorporated (AnalogicTech) (Nasdaq: AATI), a developer of power management semiconductors for mobile consumer electronic devices, today reported financial results for the first quarter ended March 31, 2007.

Revenue for the first quarter of 2007 was $21.1 million, an increase of 15% over revenue of $18.3 million for the first quarter of 2006 and a slight sequential increase from the revenue of $21.0 million for the fourth quarter of 2006.

On a GAAP basis, net loss for the first quarter of 2007 was $2.8 million, or $0.06 per diluted share. This compares to GAAP net income of $0.7 million, or $0.02 per diluted share, for the first quarter of 2006, and a GAAP net loss of $2.6 million, or $0.06 per diluted share, for the fourth quarter of 2006. The Company recorded stock-based compensation expense of $1.7 million, $1.4 million and $1.8 million in the first quarter of 2007, the first quarter of 2006 and the fourth quarter of 2006, respectively.

On a Non-GAAP basis, excluding loss on liquidation of a branch office of $0.3 million and amortization of acquired intangibles of $0.3 million, net of tax, net loss for the first quarter of 2007 was $2.2 million, or $0.05 per diluted share. This compares to Non-GAAP net income of $0.7 million, or $0.02 per diluted share for the first quarter of 2006, and a net loss of $1.9 million, or $0.04 per diluted share for the fourth quarter of 2006.

AnalogicTech reported GAAP gross margins of 52.9% for the first quarter of 2007, compared to 61.0% for the first quarter of 2006 and 54.3% for the fourth quarter of 2006. Non-GAAP gross margins were 54.1% for the first quarter of 2007, compared to 61.0% for the first quarter of 2006 and 55.1% for the fourth quarter of 2006.

“Revenue was up sequentially despite typical seasonality, and reached a record level for a first quarter,” stated Richard K. Williams, President, CEO and CTO of AnalogicTech. “Sales were driven by strong demand across our product lines with particular strength in our lighting and display solutions and voltage regulation categories. We are pleased with our continued progress on migrating product development activities to our proprietary ModularBCD process technology, and recently introduced the first 12-Volt device using our patented process technology. We are encouraged by customer demand for integrated power solutions across a wide range of end applications, and we are continuing to build a robust product pipeline to address these exciting growth opportunities.”

Business Outlook

The following statements are based upon management’s current expectations. These statements are forward-looking, and actual results may differ materially. AnalogicTech undertakes no obligation to update these statements.

For the second quarter ending June 30, 2007, AnalogicTech estimates revenue in the range of $23.0 to $25.0 million, and, on a GAAP basis, a net loss of $0.05 to $0.03 per diluted share. The second quarter 2007 GAAP estimates include pre-tax quarterly share-based compensation expense of $2.0 to $2.2 million.

Non-GAAP Reporting

In addition to GAAP reporting, AnalogicTech reports net income and gross margins on a Non-GAAP basis. This Non-GAAP earnings information excludes amortization of acquired intangibles, loss on liquidation of a branch office, in-process research and development, restructuring and severance charges and their tax-related effects. AnalogicTech believes this Non-GAAP earnings information provides meaningful insight into the Company’s on-going performance and has therefore chosen to provide this information to investors for a more consistent basis of comparison and to emphasize the results of on-going operations. AnalogicTech also uses this information internally to evaluate and manage the Company’s operations and to determine incentive compensation. A reconciliation between GAAP and Non-GAAP gross margin and net income is included in the tables below.
