Commenting on the results for the quarter ended July 3, 2010, Ralph Quinsey, President and Chief Executive Officer, stated “TriQuint had a strong second quarter, passing the $200 million a quarter revenue milestone and exceeding our non-GAAP operating income target of 15% on a healthy mix of higher margin Networks products. I now expect year over year revenue growth to be 25-30% based on continued strong smartphone design wins and market growth.”

Summary Financial Results for the Quarter Ended July 3, 2010:

Revenue for the second quarter of 2010 was $207.5 million, up 23% from the second quarter of 2009. Networks products continued to enjoy a strong rebound from the lows of 2009 growing 19% sequentially and 64% year over year.

Net income for the second quarter of 2010 was $22.5 million, or $0.14 per diluted share. Non-GAAP net income for the second quarter was $33.1 million, or $0.20 per diluted share. Please see our discussion of non-GAAP financial measures below and the attached supplemental schedule for a reconciliation of GAAP to non-GAAP financial measures.

Gross margin for the second quarter of 2010 was 41.2%, up from 32.3% in the second quarter of 2009. On a non-GAAP basis, gross margin improved for the fifth consecutive quarter to 42.3%, up from 33.2% in the second quarter of 2009. Gross margin improved sequentially due to strong factory utilization, a higher mix of networks and defense product revenue and favorable product mix.

Operating expenses for the second quarter of 2010 were $58.8 million, or 28.3% of revenue, up from $50.3 million, or 29.8% of revenue in the second quarter of 2009. Non-GAAP operating expenses for the quarter were $54.7 million or 26.4% of revenue, up 4.4% sequentially. Most of the increase was in research and development expenses.

Outlook:

The Company believes third quarter revenue will be between $215 million and $225 million, up about 6% sequentially. We expect strong growth in our mobile devices market will lead to a non-GAAP gross margin between 40% and 41%. Non-GAAP operating expenses are expected to grow to about $57 million. Third quarter net income is expected to be about $0.20 per share on a non-GAAP basis.

Non-GAAP Financial Measures:

This press release provides financial measures for net income, diluted earnings per share, gross profit, operating expenses and operating income that exclude equity compensation expense, non-cash tax expense, certain charges associated with acquisitions, and other specifically identified non-routine items, and are therefore not calculated in accordance with accounting principles generally accepted in the United States (“GAAP”). This press release includes two newly added adjustments to non-GAAP measures, a charge for restructuring relating to the closure of our Colorado office and non-cash tax expense. The non-cash tax expense includes certain deferred tax charges and benefits that do not result in a tax payment or tax refund. For comparative purposes, the Q1 2010 non-GAAP numbers have been revised to show the effects of the non-cash tax expense. Management believes that these non-GAAP financial measures provide meaningful supplemental information regarding our performance that enhances management’s and investors’ ability to evaluate TriQuint’s operating results.
