AnalogicTech Reports Financial Results for the Third Quarter 2009

Santa Clara, CA – October 28, 2009 – Advanced Analogic Technologies, Inc. (“AnalogicTech” or the “Company”) (Nasdaq: AATI), an analog semiconductor company focused on powering innovative solutions in consumer, industrial, and telecom markets, today reported financial results for the third quarter ended September 30, 2009.

Net revenue for the third quarter of 2009 was $26.1 million, an increase of 3% over net revenue of $25.4 million for the third quarter of 2008 and a sequential increase of 14% from net revenue of $23.0 million for the second quarter of 2009.

In accordance with U.S. generally accepted accounting principles (GAAP), net loss for the third quarter of 2009 was $1.0 million, or $0.02 per diluted share. This compares to GAAP net loss of $0.7 million, or $0.02 per diluted share for the third quarter of 2008, and GAAP net loss of $2.5 million, or $0.06 per diluted share for the second quarter of 2009.

On a non-GAAP basis, excluding stock-based compensation expense, amortization of acquired intangibles, net of taxes, net income for the third quarter of 2009 was $0.8 million, or $0.02 per diluted share. This compares to non-GAAP net income of $0.5 million, or $0.01 per diluted share, for the third quarter of 2008 and non-GAAP net loss of $0.8 million, or $0.02 per diluted share, for the second quarter of 2009. Non-GAAP net income for the third quarter of 2008 excluded stock-based compensation expense, amortization of acquired intangibles, restructuring and other severance-related expense, net of taxes. Non-GAAP net loss for the second quarter of 2009 excluded stock-based compensation expense, amortization of acquired intangibles expenses, restructuring and other severance-related expense, net of taxes.

AnalogicTech reported gross margins of 51.2% for the third quarter of 2009, compared to 50.0% for the third quarter of 2008 and 48.3% for the second quarter of 2009. Non-GAAP gross margin was 51.7% for the third quarter of 2009, compared to 51.4% for the third quarter of 2008 and 48.9% for the second quarter of 2009. The Company ended the quarter with $103.1 million in cash, cash equivalents, and short-term investments.

“Our third quarter results exceeded expectations for sales, gross margin and non-GAAP earnings per share,” stated Richard K. Williams, President, CEO and CTO of AnalogicTech. “We were pleased to experience strong sequential growth, particularly following the tremendous increase in sales last quarter. We continued to see an increasing revenue contribution from our battery management products, which grew by more than 60% from last quarter. This growing business segment expands our ability to address new applications. Revenue from our ModularBCD products also continued to grow in the third quarter.”

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 fourth quarter ending December 31, 2009, AnalogicTech estimates revenue in the range of $19 million to $23 million, and net loss in the range of $0.11 to $0.07 per diluted share on a GAAP basis. The fourth quarter 2009 estimates include pre-tax quarterly share-based compensation expense in the range of $1.9 to $2.1 million.

Non-GAAP Reporting

In addition to GAAP reporting, AnalogicTech reports net income (loss), gross margin and earnings (loss) per share on a non-GAAP basis. This non-GAAP earnings information excludes certain items and their tax-related effects. AnalogicTech believes this non-GAAP earnings information provides meaningful insight into the Company’s ongoing operational performance and has therefore chosen to provide this information to investors as an additional dimension of comparability to similar companies. AnalogicTech also uses this information internally to evaluate and manage company operations and to determine incentive compensation. A reconciliation between GAAP and non-GAAP net income (loss), gross margin and earnings (loss) per share is included in the tables below.

The non-GAAP information included in this press release is not necessarily comparable to non-GAAP information of other companies. Non-GAAP information should not be viewed as a substitute for, or superior to, net income or other data prepared in accordance with GAAP as measures of our profitability or liquidity. Users of this financial information should consider the types of events and transactions for which adjustments have been made.
