Summary Financial Results for the Quarter:

•The revenue, gross margin and pro-forma EPS are all in line with the Company’s guidance given on June 5, 2003.

•Revenue in the quarter was $72.8 million, up 19% compared to the second quarter of 2002 and up 1.6% compared to the first quarter of 2003. The revenue for the quarter ended June 30, 2003, included $8.7 million from the recently acquired optoelectronics business.

•Net loss for the quarter based on accounting principles generally accepted in the United States of $59.6 million was equal to a loss of $0.45 per share and included:

•$42 million non-cash charge due to conversion of our semiconductor fabrication facility in Richardson, Texas, from a leased asset to an owned asset.

•$2.6 million of severance related costs.

•$8.7 million of losses from the recently acquired optoelectronics business.

Excluding the $42 million non-cash lease termination charge and the $2.6 million in severance costs, TriQuint had a pro-forma net loss of $15 million, equal to a pro-forma loss of $0.11 per share. Please see the attached supplemental pro-forma disclosures for a reconciliation of GAAP results to pro-forma results.

•Gross margin was 25.7%.

•Cash, short-term investments, and long-term marketable securities total $401.3 million at June 30, 2003. All of these investments are high quality corporate and government securities such as commercial paper, money market funds, notes and short-term bonds.

Commenting on the results for the quarter ended June 30, 2003, Ralph Quinsey, President and CEO, stated, “While we are disappointed to post a loss for the quarter, it was in line with our previous guidance. We are encouraged by our activity in wireless handsets, the WLAN market and the modest rebound in our optoelectronics business. The quick acceptance and design-in of our recently announced new products, including our family of GSM power amplifier modules, our industry leading 3.8mm cellular duplexer and our growth in 802.11 wireless local area networks (WLAN) validates our wireless strategy of supplying the market with RF products and solutions that improve the performance and lower the cost of our customers’ applications. Additionally, we believe our first sequential growth quarter in optoelectronics marks the turning point in our investment for this market. Our focus continues to be the rapid introduction of new products in all of our markets leveraging our core competence across a diversity of opportunities.”

Outlook for the Third Quarter and the balance of 2003:

TriQuint is forecasting revenue for the quarter ending September 30, 2003, to be similar to the revenue for the quarter ended June 30, 2003, with a projected range of $70 million to $74 million. The gross margin for the third quarter of 2003 is also expected to be similar to the second quarter with a range of 24% to 27%. Operating expenses are expected to decrease due to some of the cost initiatives recently put in place and are projected to be between $28 million and $30 million for the third quarter. TriQuint expects to post a loss per share of between $0.08 and $0.11 for the third quarter.

Revenue and gross margins are expected to improve slightly in the fourth quarter of 2003 and operating expenses are projected to further decline, reducing the projected loss per share to between $0.05 and $0.08.

* To supplement our consolidated financial statements presented in accordance with GAAP, TriQuint uses non-GAAP measures of pro forma net income and pro forma earnings per share, which are adjusted from our GAAP results to exclude certain non-cash charges, severance costs and gains.  These non-GAAP adjustments are provided to enhance the user’s overall understanding of our current financial performance and our prospects for the future.  We believe the non-GAAP results provide useful information to both management and investors by excluding certain charges and other amounts that we believe are not indicative of our core operating results.  These non-GAAP measures are included to provide investors and management with an alternative method for assessing TriQuint’s operating results in a manner that is focused on the performance of TriQuint’s ongoing operations and to provide a more consistent basis for comparison between quarters.  Further, these non-GAAP results are one of the primary indicators management uses for planning and forecasting in future periods. In addition, since we have historically reported non-GAAP results to the investment community, we believe the inclusion of non-GAAP numbers provides consistency in our financial reporting.  The presentation of this additional information should not be considered in isolation or as a substitute for results prepared in accordance with accounting principles generally accepted in the United States.
