AnalogicTech Reports Financial Results for the Second Quarter 2009

Santa Clara, CA – July 22, 2009 – Advanced Analogic Technologies, Inc. ("AnalogicTech" or the "Company") (Nasdaq: AATI), a developer of total power management integrated circuits, today reported financial results for the second quarter ended June 30, 2009.

Net revenue for the second quarter of 2009 was $23.0 million, an increase of 9% over net revenue of $21.2 million for the second quarter of 2008 and a sequential increase of 39% from net revenue of $16.5 million for the first quarter of 2009.

In accordance with U.S. generally accepted accounting principles (GAAP), net loss for the second quarter of 2009 was $2.7 million, or $0.06 per diluted share. This compares to GAAP net loss of $3.8 million, or $0.08 per diluted share for the second quarter of 2008, and GAAP net loss of $5.2 million, or $0.12 per diluted share for the first quarter of 2009.

On a non-GAAP basis, excluding stock-based compensation expense, amortization of acquired intangibles, restructuring and other severance-related expenses, net of taxes, net loss for the second quarter of 2009 was $0.8 million, or $0.02 per diluted share. This compares to non-GAAP net loss of $1.8 million, or $0.04 per diluted share, for the second quarter of 2008 and non-GAAP net loss of $3.5 million, or $0.08 per diluted share, for the first quarter of 2009. Non-GAAP net loss for the second quarter of 2008 excluded stock-based compensation expense, amortization of acquired intangibles, in-process research and development, restructuring and other severance-related expense, net of taxes. Non-GAAP net loss for the first quarter of 2009 excluded stock-based compensation expense, amortization of acquired intangibles, restructuring and other severance-related expenses, net of taxes.

AnalogicTech reported gross margins of 48.3% for the second quarter of 2009, compared to 47.3% for the second quarter of 2008 and 44.9% for the first quarter of 2009. Non-GAAP gross margin was 48.9% for the second quarter of 2009, compared to 48.9% for the second quarter of 2008 and 45.6% for the first quarter of 2009. The Company ended the quarter with $104.7 million in cash, cash equivalents, and short-term investments.

“Our second quarter results significantly exceeded expectations with revenue increasing 39% sequentially,” stated Richard K. Williams, President, CEO and CTO of AnalogicTech. “Sales across all major geographies were up, with the strongest growth occurring in China and Taiwan, driven by strong demand for our computing and communications products. We were also encouraged to see sales from both battery management and voltage regulation products more than double sequentially in the second quarter, reflecting our success in penetrating new applications with our expanding product portfolio. Revenue from our ModularBCD products also grew in the second quarter and continued to represent a strong percentage of our sales.”

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 third quarter ending September 30, 2009, AnalogicTech estimates revenue in the range of $24 million to $26 million, and net loss in the range of $0.07 to $0.05 per diluted share on a GAAP basis. The third quarter 2009 estimates include pre-tax quarterly share-based compensation expense in the range of $1.7 to $1.9 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.
