TRIQUINT SEMICONDUCTOR, INC. ANNOUNCES RESULTS
FOR THE QUARTER AND YEAR ENDED DECEMBER 31, 2004

Hillsboro, Oregon – February 7, 2005 - TriQuint Semiconductor, Inc. (Nasdaq: TQNT) today reported its financial results for the quarter and year ended December 31, 2004.

Summary Financial Results and Highlights for the Quarter Ended December 31, 2004:

•Revenues of $74.7 million were slightly above guidance but declined from both the third quarter of 2004 and from the fourth quarter of 2003 due to lower sales of products for the wireless phone, base station and wireless LAN markets.

•Net loss after tax on the basis of accounting principals generally accepted in the U.S. (GAAP) was $25.3 million. Included in the GAAP net loss are several large items related to the repositioning of the Company’s optoelectronics strategy. Excluding these and other charges, the Company had a pro-forma net loss of $8.9 million, equal to a per share loss of $0.06 in line with the guidance on December 14, 2004. A full reconciliation of our GAAP to pro-forma results is included in this press release.

•Cash, cash equivalents and short and long term marketable securities increased $25.5 million from the end of the third quarter and were $388.3 million as of December 31, 2004.

•The Company successfully completed significant cost reduction initiatives announced in the fourth quarter of 2004 with respect to its optoelectronics product line.

•The Company completed the previously announced acquisition of TFR Technologies, Inc., on January 5, 2005. This acquisition adds bulk acoustic wave (BAW) filtering technology to the Company’s product portfolio. BAW technology is critical to developing higher frequency filters for next generation wireless communication products.

Summary Financial Results and Highlights for the Year Ended December 31, 2004:

•Revenues of $347 million for 2004 increased 11.1% over revenues of $312.3 million for 2003 and were TriQuint’s second highest annual revenues. Revenues increased for the wireless phone, base station and broadband markets, were down slightly in defense, and up slightly in optoelectronics compared to 2003.

•The Company shipped a record number of components and devices for the year.

•The net loss on a GAAP basis improved from a loss of $73 million in 2003 to a loss of $29.1 million in 2004 and the pro forma net loss improved from a loss of $33.3 million in 2003 to a loss of $16.8 million in 2004.

•Cash, cash equivalents, and short and long term marketable securities, net of the convertible notes, increased by $33.1 million in 2004 and were $164.6 million as of December 31, 2004.

Commenting on the results for the quarter and year ended December 31, 2004, Ralph Quinsey, President and CEO, stated, “TriQuint Semiconductor successfully penetrated the GSM/GPRS market in 2004 and took aggressive cost restructuring actions in the fourth quarter to reduce the losses in our optoelectronics product line. With close to three times revenue growth in the GSM/GPRS market, we are on track to becoming a significant supplier in this billion dollar market. We are actively sampling our ‘world’s smallest’ products – including a 5 mm x 5 mm GSM/GPRS power amplifier module and a 6 mm x 6 mm GSM/GPRS transmit module – a device that includes both the power amplifier and switch functions for a tri- or quadband handset. We expect to be shipping production in the first quarter of 2005. We have significantly increased our participation in the GSM/GPRS RF filter market with the success of our quad band filter bank module. While we expect revenues in the first quarter of 2005 to be seasonally weaker than the fourth quarter, we expect subsequent quarters of 2005 to be sequential growth quarters.”

Outlook for 2005:

The Company’s focus for 2005 is to restore profitability, continue to generate positive cash flow and to build on its success in wireless phones, base stations, broadband wireless access and the defense markets, and to move forward with its new strategy for the optoelectronics market.

Revenues for the first quarter of 2005 are expected to be seasonally down 5% to 7% compared to the fourth quarter of 2004 due to seasonal factors including slightly lower sales for products for wireless phones as well as the planned reduction in optoelectronic revenue as a result of elimination of some product lines. Some costs from the optoelectronics restructuring estimated at $800,000 will carry over to Q1 2005 as well as acquisition related charges, estimated at $2 million for the acquisition of TFR Technologies. Absent these costs, the Company is expecting a gross margin at between 22% and 24% and a loss per share of between $0.07 and $0.08. These charges are projected at approximately $2.8 million and increase the projected loss by $0.02 per share for a total projected loss per share of $0.09 to $0.10.

For the full year, the Company expects revenue to be essentially flat to revenue in 2004 with improved profitability.

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

TriQuint will host a conference call this afternoon at 2:00 PM PDT to discuss the results for the quarter as well as future expectations of the Company.

* 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 other gains and losses. 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.
