Summary Financial Results for the Quarter:

• The revenue, gross margin and EPS are all significantly improved over the results for the third quarter of 2003 and are at or above the guidance given on December 10, 2003, due to strong results in December.

• Revenue in the quarter of $89 million, up 13% over third quarter of 2003 and up 22.4% over the fourth quarter of 2002 is the Company’s highest quarterly revenue since the first quarter of 2001.

• The gross margin improved to 32.5%, compared to 29.8% in the third quarter of 2003, principally due to increased volume.

• Operating expenses, consisting of engineering, research and development, sales and marketing, and administration, decreased to $26.3 million compared to $27.4 million in the third quarter of 2003.

• Operating income of $2.6 million for the fourth quarter of 2003 compares to operating losses in the previous eight quarters.

• A net profit after tax on a GAAP basis of $8.9 million, equal to $0.06 per diluted share compares to a loss in the third quarter of $5.8 million. The results include a one-time gain net of other impairments of $6.2 million from the settlement of a previously impaired promissory note and an income tax benefit of $1.9 million due to settlements of prior year taxes.

• Cash, cash equivalents and short and long term investments increased by $22.3 million during the fourth quarter to $400.3 million at quarter end.

Summary Financial Results for the Year Ended December 31, 2003:

• Revenues were $312.3 million for 2003 which was an increase of 16.8% over the revenues of $267.3 million for 2002, due to improved sales of products for wireless phones and inclusion of the results of TriQuint Optoelectronics for the full year.

• The net loss on a GAAP basis improved from a loss of $158.6 million in 2002 to $73.0 million in 2003. The results from both years include several significant items which are more fully explained on the enclosed supplemental pro-forma reconciliation.

Commenting on the results for the quarter and year ended December 31, 2003, Ralph Quinsey, President and CEO, stated, “I am pleased with our performance during the fourth quarter. We believe our strategic focus and the investments we put in place last year are beginning to yield results. In 2004, we expect to see continued success with our new products and the favorable impact of a stronger economic environment across our diversified markets.”

Outlook for the First Quarter and Full Year 2004:

For the quarter ending March 31, 2004, TriQuint is raising revenue guidance from a range of $77 million to $80 million, previously forecasted to a range of $81 million to $83 million with a gross profit margin of 31% to 33%. TriQuint projects operating expenses will range from $28 million to $29 million producing breakeven to a slight operating loss for the first quarter of 2004. TriQuint expects its net loss after interest expense and taxes to be between $1 million and $3 million. The guidance is being raised due to continued strong shipments and bookings to date in the first quarter of 2004.

TriQuint is forecasting its revenue for the full year 2004 to improve over 2003 due to continued strength in the wireless phone market, coupled with stability in the optical network market, recovery in the network infrastructure market and a stable outlook for our defense business. TriQuint expects revenues for the full year to increase at least 10% over the 2003 results and to range from $340 million to $355 million. TriQuint also anticipates that its gross margin will improve and will range from 32% to 34% for 2004 compared to 27.9% for 2003. TriQuint expects its operating income to improve substantially from a loss of $74.4 million in 2003 to near breakeven or better for 2004.

A summary table of TriQuint’s financial guidance for 2004 is available on the “Investors” section of TriQuint’s web site.

* 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.
