Summary Financial Results and Highlights for the Quarter and Year Ended December 31, 2006:

Revenues for the fourth quarter of 2006 totaled $114.3 million. Revenues for the year ended December 31, 2006, totaled $401.8 million. Revenues from continuing operations for the fourth quarter of 2005 were $84.7 million and for the year ended December 31, 2005 were $294.8 million.

Net income for the fourth quarter of 2006 was $6.4 million or $0.05 per diluted share and $8.4 million or $0.06 per diluted share excluding $2.0 million of equity compensation expense. For the year ended December 31, 2006 net income was $22.4 million or $0.16 per diluted share and $31.5 million or $0.22 per diluted share excluding equity compensation expense of $9.1 million.

Our results for the quarter and year ended December 31, 2006, reflect the effect of the adoption of Statement of Financial Accounting Standards (“SFAS”) No. 123(R), which became effective for our company on January 1, 2006. These charges are not included in the results for periods prior to January 1, 2006. Net income for the fourth quarter of 2005 was $2.9 million or $0.02 per diluted share and for the full year of 2005 was $4.0 million or $0.03 per diluted share. The earnings reported for 2005 fiscal year include net income of $8.2 million or $0.06 per diluted share from our discontinued optoelectronic operations, primarily from the sale of these operations.

Gross margin for the fourth quarter of 2006 was 29.4%, compared to 31.8% for the third quarter of 2006. Our margins for the fourth quarter were affected by new product ramp costs, scheduled facility shut-downs and other costs. Excluding equity compensation expense our gross margin for the fourth quarter of 2006 was 29.9%, compared to 28.7% for the fourth quarter of 2005. This increase in margin was primarily due to capacity utilization improvements in 2006, partially offset by the product ramp costs in the fourth quarter of 2006. For the year ended December 31, 2006, our gross margin was 30.8%. Excluding equity compensation expense our gross margin for 2006 was 31.6%, compared to 28.6% for the year ended December 31, 2005. The increased margin in 2006 was primarily due to increased factory utilization.

Operating expenses for the fourth quarter of 2006 were $26.4 million or 23.1% of revenue. Excluding equity compensation expenses our operating expenses for the fourth quarter of 2006 were $25.0 million, as compared to $21.7 million for the fourth quarter of 2005, or 21.9% of revenue in the fourth quarter of 2006 compared to 25.6% in the fourth quarter of 2005.

Cash, cash equivalents and short and long term marketable securities were $373.2 million as of December 31, 2006, essentially flat compared to September 30, 2006. During the fourth quarter of 2006, TriQuint completed its $25.0 million stock repurchase program by repurchasing approximately 450,000 shares at a cost of approximately $2.3 million. Additionally, the Company acquired approximately $13 million of capital assets during the quarter. Depreciation and amortization expense for the fourth quarter of 2006 was approximately $7.8 million. In 2006 our cash, cash equivalents and short and long term marketable securities decreased $33.5 million, primarily due to the repurchase of $25.0 million of stock and acquisition of approximately $40 million in capital assets, partially offset by cash provided by operations and cash received from the issuance of stock.

We expect to pay our convertible bonds due March 1, 2007 out of existing cash balances. Our net cash and investments after we retire the debt is expected to be approximately $150.0 million.

Operating cash flow was approximately $10 million for the fourth quarter of 2006 and approximately $22 million for the full year 2006.

Commenting on the results for the quarter and year ended December 31, 2006, Ralph Quinsey, President and Chief Executive Officer, stated, “our strategy of being a focused supplier of RF power, filtering and switching technology in highly integrated solutions is gaining traction with both customers and chipset partners alike. TriQuint’s design win success in 2006 placed us in approximately 97 new phone models and we estimate TriQuint’s share in the handset market has grown to approximately 8 to 9%. Our military business remains strong and our standard products revenue is growing. I am delighted with the 433% improvement in earnings delivered by our team in 2006.”

Outlook for the First Quarter of 2007:

Revenues and earnings for the first quarter of 2007 are expected to be slightly down from the fourth quarter of 2006. We estimate our first quarter revenues in the range of $106 million to $110 million. Earnings per diluted share are expected to be in the range of $0.03 to $0.05. Equity compensation expense is expected to be approximately $2 million in the first quarter of 2007.

Outlook for 2007

Revenues in 2007 are expected to grow 18% to 20% over 2006. Net income is expected to grow between 40% and 50% in 2007 over 2006.
