NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(In thousands, except per share amounts)

(Unaudited)

1. Basis of Presentation

The accompanying condensed consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States (“GAAP”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed, or omitted, pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). In addition, the preparation of financial statements in conformity with GAAP requires management to make estimates and judgments that affect the amounts reported in the financial statements and accompanying notes. For TriQuint Semiconductor, Inc. (the “Company”), the accounting estimates requiring management’s most difficult and subjective judgments include revenue recognition, the valuation of inventory, the accounting for income taxes, precious metals reclaim and stock-based compensation. Certain reclassifications have been made to prior year balances in order to conform to the current year presentation. In the opinion of management, the condensed consolidated financial statements include all material adjustments, consisting only of normal, recurring adjustments, necessary for the fair presentation of the results of the interim periods presented. These condensed consolidated financial statements should be read in conjunction with the audited financial statements of the Company as of and for the fiscal year ended December 31, 2013, included in the Company’s 2013 Annual Report on Form 10-K filed with the SEC on February 21, 2014.

2.     Recent Accounting Pronouncements

On May 28, 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers, which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The ASU will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. The new standard is effective for the Company on January 1, 2017. Early application is not permitted. The standard permits the use of either the retrospective or cumulative effect transition method. The Company is evaluating the effect that ASU 2014-09 will have on its consolidated financial statements and related disclosures. The Company has not yet selected a transition method nor has it determined the effect of the standard on its ongoing financial reporting.

3.    Fair Value of Financial Instruments

The Company accounts for its assets utilizing a hierarchy of valuation techniques based on whether the inputs to those valuation techniques are observable or unobservable. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect the Company’s market assumptions. These two types of inputs have created the following fair-value hierarchy:

• Level 1—Quoted prices for identical instruments in active markets;

• Level 2—Quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets; and

• Level 3—Valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable.

There were no transfers between Level 1, Level 2 or Level 3 fair value measurements during the three or six months ended June 28, 2014 and June 29, 2013.

The Company's non-qualified deferred compensation plan provides eligible employees and members of the Board of Directors with the opportunity to defer a specified percentage of their cash compensation. The Company includes the asset deferred by the participants in Other noncurrent assets, net on its consolidated balance sheets and the Company’s obligation to deliver the deferred compensation in Other long-term liabilities on its consolidated balance sheets.

The Company's earnout and milestone payment liability as of June 28, 2014 resulted from two acquisitions during 2012 and represents the fair value of the estimated payout to the former businesses contingent upon meeting certain requirements. For the first acquisition, as of June 28, 2014, the Company estimated the fair value of the obligation as $584 using a cash flow based approach discounted with a market discount rate. For the second acquisition, as of June 28, 2014, the Company estimated the fair value of the obligation as $1,482 using a Monte Carlo simulation model discounted using the risk free rate adjusted for an applicable credit spread. During the six months ended June 28, 2014, the Company remeasured the fair value of its obligations based on a change in forecast related to the achievement of earnout targets. The change in estimate resulted in a decrease to the liability of $279 in aggregate and was recorded to selling, general and administrative expenses in the statement of operations. For both of the acquisitions, total accretion of $445 was recognized during the six months ended June 28, 2014.

Financial Instruments Not Recorded at Fair Value on a Recurring Basis

The Company entered into two separate cross-licensing agreements, one in 2012 and another in the first quarter of 2014. The fair value of the first cross-licensing agreement was estimated using a discounted cash flow model which discounted the future cash flows using an incremental borrowing rate of 9%. The fair value of the second cross-licensing agreement was estimated using a discounted cash flow model which discounted the future cash flows using an incremental borrowing rate of 5%. These cross-licensing liabilities are categorized as Level 3 in the fair-value hierarchy and the ending fair value at June 28, 2014 was $14,144, of which $2,540 was current and is included in other accrued liabilities on the consolidated balance sheets.

4.    Investments in Cash Equivalents and Marketable Securities

As of June 28, 2014 and December 31, 2013, cash equivalents and short-term investments were classified as available-for-sale. Cash equivalents had maturity dates of less than 90 days at the date acquired, and short-term investments had maturity dates of less than one year, from the date of purchase. All unrealized gains and losses on available-for-sale investments are included in Other comprehensive income (loss). The cost, net unrealized holding gains, net unrealized holding losses and fair value of available-for-sale investments by types and classes of security at June 28, 2014 consisted of the following:

At June 28, 2014	Cost		Net unrealized holding gains		Net unrealized holding losses			Fair Value
Available-for-sale-included in cash equivalents:
Money market funds	$	111,934	$	—	$	—		$	111,934
Corporate debt securities	8,998		—		—			8,998
Available-for-sale-included in short-term marketable securities:
Corporate debt securities	8,981		—		(2		)	8,979
Long-term investments included in Other noncurrent assets, net:
Corporate debt securities	1,014		—		—			1,014
	$	130,927	$	—	$	(2	)	$	130,925

The cost, net unrealized holding gains, net unrealized holding losses and fair value of available-for-sale investments by types and classes of security at December 31, 2013 consisted of the following:

At December 31, 2013	Cost		Net unrealized holding gains		Net unrealized holding losses		Fair Value
Available-for-sale-included in cash equivalents:
Money market funds and other	$	25,904	$	—	$	—	$	25,904
	$	25,904	$	—	$	—	$	25,904

Investments are considered to be impaired when a decline in fair value is judged to be other-than-temporary. The Company employs a methodology that reviews specific securities in evaluating potential impairment of its investments. In the event that the cost of an investment exceeds its fair value, the Company evaluates, among other factors, the Company’s intent and ability to hold the investment and extent to which the fair value is less than cost; the financial health of and business outlook for the issuer; and operating and financing cash flow factors. During the three and six months ended June 28, 2014, the Company did not record any other-than-temporary impairments on its investments in cash equivalents.

5.    Net Earnings (Loss) Per Share

Net earnings (loss) per share is presented as basic and diluted net earnings (loss) per share. Basic net earnings (loss) per share is net earnings (loss) available to common stockholders divided by the weighted-average number of common shares

6

outstanding. Diluted net earnings per share is similar to basic net earnings (loss) per share, except that the denominator includes potential common shares that, had they been issued, would have had a dilutive effect. Dilutive securities include options granted pursuant to the Company’s stock option plans, and potential shares related to Restricted Stock Units ("RSUs"), Market-Based Restricted Stock Units ("MSUs") and the Company’s Employee Stock Purchase Plan ("ESPP").

The following is a reconciliation of the basic and diluted shares:

	Three Months Ended					Six Months Ended
	June 28, 2014		June 29, 2013			June 28, 2014			June 29, 2013
Net income (loss):	$	5,210	$	(14,885	)	$	(13,859	)	$	(42,834	)
Shares for net income (loss) per share:
Weighted-average shares outstanding—Basic	171,770		159,347			168,140			160,044
Dilutive securities	9,549		—			—			—
Weighted-average shares outstanding—Diluted	181,319		159,347			168,140			160,044

For the three months ended June 28, 2014, no potential shares were excluded from the calculation. For the six months ended June 28, 2014 and the three and six months ended June 29, 2013, potential shares of 8,949, 4,024, and 3,216, respectively, related to RSUs, MSUs and the ESPP were excluded from the calculation as their effect would have been antidilutive.

8.    Goodwill and Other Acquisition-Related Intangible Assets

The Company is required to perform an impairment analysis on its goodwill at least annually, or when events and circumstances warrant. Conditions that would trigger an impairment assessment, include, but are not limited to, a significant adverse change in legal factors or in the business climate that could affect the value of an asset or an adverse action or assessment by a regulator. The Company is considered one reporting unit. When the Company performed this test in 2013, the Company elected to use the two-step goodwill impairment test. Therefore, to determine whether goodwill may be impaired, the Company compares its book value to its market capitalization. If the trading price of the Company’s common stock, as adjusted for factors such as a control premium, is below the book value per share at the date of the annual impairment test or if the average trading price of the Company’s common stock is below book value per share for a sustained period, a goodwill impairment test will be performed by comparing book value to estimated market value. If the comparison of book value to estimated market value indicates impairment, then the Company compares the estimated market value of goodwill to its carrying amount in a manner similar to a purchase price allocation for a business combination. If the carrying amount of goodwill exceeds its estimated market value, an impairment loss is recognized equal to that excess.

Unless indicators warrant testing at an earlier date, the Company performs its annual goodwill impairment test in the fourth quarter of each year. During the six months ended June 28, 2014, there were no impairments recorded.

Information regarding the Company’s acquisition-related intangible assets is as follows:

	Three Months Ended				Six Months Ended
	June 28, 2014		June 29, 2013		June 28, 2014		June 29, 2013
Amortization expense	$	1,459	$	1,766	$	2,930	$	3,532

The Company abandoned and wrote off $213 relating to one product line that was included in in-process research and development during the three months ended June 28, 2014. The Company abandoned and wrote off $425 relating to two product lines that were included in in-process research and development during the six months ended June 28, 2014. These charges were recorded to research, development and engineering expense in the statement of operations. There were no similar charges during the three or six months ended June 29, 2013.

During the three and six months ended June 28, 2014, one product line that was included in in-process research and development reached technological feasibility. As a result, the Company transferred $212 to developed technology, and began amortizing this amount over a period of eight years. There were no similar transfers during the three or six months ended June 29, 2013.

The Company acquired developed technology of $375 and patents of $150 during the three and six months ended June 28, 2014, that will be amortized over a period of eight years and seventeen years, respectively. There were no similar acquisitions during the three or six months ended June 29, 2013.

9.    Credit Facility

On September 30, 2010, the Company, the domestic subsidiaries of the Company (the “Guarantors”), Bank of America, N.A., as administrative agent and lender, and Union Bank, N.A., Wells Fargo Bank, N.A., Bank of the West, BBVA Compass Bank and US Bank, as lenders (together with the administrative agent, the “Lenders”), entered into a Credit Agreement (the “Agreement”). The Agreement provided the Company with a three-year unsecured revolving syndicated credit facility of $200,000 maturing on September 30, 2013. On August 24, 2011, the Company extended, with the Lenders' consent, the maturity date to September 30, 2014. The Company’s obligations under the Agreement are jointly and severally guaranteed by the Guarantors. Upon the occurrence of events of default specified in the Agreement, amounts due under the Agreement may be declared immediately due and payable.

9

The Company may elect to borrow at either a Eurodollar Rate or a Base Rate (each as defined in the Agreement). Eurodollar Rate loans bear interest at an amount equal to the sum of a rate per annum calculated from the British Bankers Association London Interbank Offered Rate ("LIBOR") plus a designated percentage per annum (the “Applicable Rate”). The Applicable Rate for Eurodollar Rate loans is based on the Company’s consolidated total leverage ratio (as defined in the Agreement) and is subject to a floor of 2.50% per annum and a cap of 3.00% per annum. Base Rate loans bear interest at a rate equal to the higher of the federal funds rate plus 0.50%, the prime rate of Bank of America, N.A. plus the Applicable Rate or the Eurodollar Base Rate plus 1.0%. The Applicable Rate for Base Rate loans is subject to a floor of 1.50% per annum and a cap of 2.00% per annum. The interest payment date (as defined in the Agreement) will vary based on the type of loan but generally will be quarterly. The Company paid commitment fees, an arrangement fee, upfront fees and a renewal fee pursuant to the terms of the Agreement. The Company will also pay a quarterly fee for any letters of credit issued under the Agreement. The initial fees associated with the Agreement were capitalized and are being amortized to interest expense using the straight-line method over the remaining term to maturity.

The Agreement contains non-financial covenants of the Company and the Guarantors, including restrictions on the ability to create, incur or assume liens and other debt, make certain investments, dispositions and restricted payments, change the nature of the business, and merge with other entities subject to certain caps as defined in the agreement. The Agreement requires the Company to maintain ratios defined in the Agreement, which include a consolidated total leverage ratio as of the end of any fiscal quarter not in excess of 2.50 to 1.00, a consolidated liquidity ratio of at least 1.25 to 1.00 and a consolidated interest coverage ratio at a minimum of 3.00 to 1.00. The Company was in compliance with these covenants as of June 28, 2014.

At June 28, 2014 and December 31, 2013, there were no amounts outstanding under the Agreement. Because there were no borrowings during the three and six months ended June 28, 2014, no interest cost was incurred on borrowings during this time. During the three and six months ended June 29, 2013, interest cost of $3 was incurred on borrowings.

10.    Stock-Based Compensation

Stock-based compensation expense consists of compensation costs related to grants of stock options, RSUs and MSUs, and to the ESPP. The table below summarizes the stock-based compensation expense for the three and six months ended June 28, 2014 and June 29, 2013:

	Three Months Ended				Six Months Ended

The following table summarizes the average estimates the Company used in the Black-Scholes option-pricing model during the three and six months ended June 28, 2014 and June 29, 2013, to determine the fair value of employee stock options granted during each period:

	Three Months Ended				Six Months Ended
	June 28, 2014		June 29, 2013		June 28, 2014		June 29, 2013
Risk free interest rates	1.7	%	0.9	%	1.7	%	0.9	%
Expected life in years	5.00 years		5.00 years		5.00 years		5.00 years
Expected dividend yield	—	%	—	%	—	%	—	%
Expected volatility	55.5	%	64.0	%	55.7	%	64.0	%
Estimated annualized forfeiture rate	5.4	%	4.9	%	5.4	%	4.9	%

Restricted Stock Units and Market Based Restricted Stock Units

RSUs are converted into shares of Company common stock upon vesting on a one-for-one basis. The awards typically vest over four years and vesting is subject to the grantee’s continued service with the Company. The compensation expense related to the service-based RSU awards is determined using the fair market value of Company common stock on the date of the grant, and the compensation expense, reduced by estimated forfeitures, is recognized over the vesting period.

The Company grants MSUs to certain members of executive management. The number of shares that are ultimately awarded is contingent upon the achievement of pre-determined market and service conditions. Market conditions must be met for shares to be awarded, even if the service conditions are met. Fair value of the awards is determined at the grant date based on the target number of awards ultimately expected to be awarded. Compensation expense associated with the awards is calculated based on the target number of shares ultimately expected to be awarded and is recognized on a straight line basis over the requisite service period and will not be reversed even if the market conditions are not met. The number of shares of common stock to be awarded will range from zero to 150 percent of the target number of stock units based on the Company's total stockholder return (“TSR”) relative to the performance of companies in the SPDR S&P Semiconductor Index ("SPDR") for the applicable measurement period. TSR is calculated based on market performance between the beginning and end of the award period, generally over three years. Based on the number of awards outstanding as of June 28, 2014, the maximum number of shares of common stock that could be awarded is 514 shares.

The fair value of the MSUs was determined using a Monte Carlo simulation model. The Monte Carlo simulation model is affected by assumptions regarding subjective and complex variables. Generally, the Company's assumptions are based on historical information and judgment is required to determine if historical trends may be indicators of future outcomes.

Key assumptions used in the Monte-Carlo simulation model to determine the fair value of MSUs granted during each period were as follows:

	Three Months Ended				Six Months Ended
	June 28, 2014		June 29, 2013		June 28, 2014		June 29, 2013
Risk free interest rates	0.9	%	0.4	%	0.9	%	0.4	%
Expected dividend yield	—		—		—		—
Expected volatility	56.2	%	56.2	%	56.2	%	56.2	%
Correlation coefficient to SPDR	0.57		0.59		0.57		0.59

The following table summarizes RSU and MSU activity for the six months ended June 28, 2014:

ESPP

Employees participating in the ESPP authorize the Company to withhold compensation and to use the withheld amounts to purchase shares of the Company's common stock at a discount.

The table below summarizes the ESPP common stock purchases for the three and six months ended June 28, 2014 and June 29, 2013.

	Three Months Ended		Six Months Ended
	June 28, 2014	June 29, 2013	June 28, 2014	June 29, 2013
Shares purchased	1,245	1,872	1,245	1,872

11.    Income Taxes

The Company recorded income tax expense (benefit) of $761 and $(2,255) for the three months ended June 28, 2014 and June 29, 2013, respectively. The Company recorded income tax (benefit) of $(936) and ($10,256) for the six months ended June 28, 2014 and June 29, 2013, respectively. The income tax expense for the three months ended June 28, 2014 was primarily the result of the Company's pre-tax income, offset by the recognition of stock-based compensation tax deductions related to disqualifying dispositions on exercises in the quarter. The income tax benefit for the six months ended June 28, 2014 is primarily the result of the Company's recognition of stock-based compensation tax deductions related to disqualifying dispositions on exercises. The income tax benefit for the three and six months ended June 29, 2013 was primarily the result of the Company's pre-tax loss, and the recognition of U.S. federal tax credits.

As of June 28, 2014, the U.S. Congress had not extended the general business credit for research and experimentation. The Company has not estimated the effect of the expiration of this credit, nor does the income tax expense for the three and six months ended June 28, 2014 reflect a benefit for the credit.

No provision has been made for the U.S., state or additional foreign income taxes related to approximately $70,500 of undistributed earnings of foreign subsidiaries which have been permanently reinvested outside the U.S. except for existing earnings that have been previously taxed. In the event of repatriation, which would generally require board approval, the earnings may be subject to an estimated $25,000 of U.S. federal and state income taxes and foreign withholding taxes.

The major jurisdictions in which the Company files tax returns are the United States, Singapore and Costa Rica. In 2012, the Company expanded its presence into Asia by increasing operations in Singapore. Due to agreements with the Costa Rican and Singaporean governments, the Company was granted income tax holidays of varying rates through March 2017 and December 2019, respectively. Incentives from these countries are subject to the Company meeting certain employment and investment requirements. The Company was in compliance with these requirements as of June 28, 2014.

Deferred Income Taxes

As of June 28, 2014, deferred tax assets of $77,661, net of a $16,243 valuation allowance, were recorded on the balance sheet. As of December 31, 2013, the Company had deferred tax assets of $74,341, net of a $16,639 valuation allowance. The Company records a valuation allowance to reduce deferred tax assets to the amount that is believed more-likely-than-not to be realized. The Company maintains a valuation allowance against the tax effect of all capital loss carryforwards, certain state and foreign net operating loss carryforwards, and certain state credit carryforwards, as management does not believe it is more likely than not that these benefits will be realized in future periods.

Unrecognized Tax Benefits

12

In the six months ended June 28, 2014, net unrecognized tax benefits increased $1,934 primarily as a result of an additional liability recorded to address existing potential exposures from positions that could be challenged by taxing authorities. Within the next 12 months, the Company believes it is reasonably possible that $1,460 of net unrecognized tax benefits may be reduced as a result of the expiration of a statute of limitations. Interest and penalties associated with unrecognized tax benefits are accrued and classified as a component of tax expense in the statement of operations and comprehensive loss.

Net unrecognized tax benefits at June 28, 2014 and December 31, 2013 were as follows:

	June 28, 2014		December 31, 2013
Net unrecognized tax benefits	$	3,996	$	2,062

12.    Commitments and Contingencies

Legal Matters

The Company is from time to time involved in litigation, certain other claims and arbitration matters arising in the ordinary course of its business. In addition, since the public announcement of the proposed business combination with RF Micro Devices, Inc. (“RFMD”) on February 24, 2014, five putative stockholder class action lawsuits have been filed against the Company, its directors, RFMD, and others in connection with the proposed mergers. Two of the five actions were filed in the Multnomah County Circuit Court in the State of Oregon: (1) Roberts vs. TriQuint Semiconductor, Inc. et al., Case No. 1402-02441, filed on February 28, 2014; and (2) Lam v. Steven J. Sharp et al., Case No. 1403-02757, filed on March 6, 2014. The other three actions were filed in the Court of Chancery of the State of Delaware: (1) Philemon v. TriQuint Semiconductor, Inc. et al., Case No. 9415-VCN, filed on March 5, 2014; (2) Schmitz v. TriQuint Semiconductor, Inc. et al., Case No. 9427-VCN, filed on March 7, 2014; and (3) Wallace v. TriQuint Semiconductor, Inc. et al., Case No. 9429-VCN, filed on March 10, 2014. Each of these lawsuits was filed on behalf of a putative class of the Company’s stockholders against the Company, the individual members of the Company’s board of directors, RFMD, Rocky Holding, Inc., and/or the to-be-formed subsidiaries of Rocky Holding, Inc. that will be used to effect the mergers. The plaintiffs in each of these lawsuits generally seek, among other things, declaratory and injunctive relief concerning alleged breaches of fiduciary duties, injunctive relief prohibiting completion of the mergers, rescission of the mergers if they are completed, an accounting by defendants, rescissionary damages, attorney’s fees and costs, and other relief. TriQuint moved to dismiss the Roberts and Lam actions filed in Oregon. Those motions to dismiss have been fully briefed and argued and are under advisement with the court. On April 29, 2014, the court orally granted the plaintiffs’ motions to consolidate the Oregon actions. On April 29, 2014, the Delaware Court of Chancery consolidated the actions filed in Delaware under the caption In re TriQuint Semiconductor, Inc. Stockholders Litigation, C.A. No. 9415-VCN. On May 1, 2014, the plaintiffs filed a consolidated amended class action complaint in the consolidated action and on May 12, 2014, the plaintiffs filed a motion for expedited proceedings and a motion for preliminary injunction seeking to enjoin defendants from taking any action to complete the proposed mergers. TriQuint opposed the motion for expedited proceedings, and the court denied the motion for expedited proceedings on June 13, 2014.

The Company believes the lawsuits to be without merit and intends to defend the lawsuits vigorously. The Company does not believe the ultimate resolution of any such pending proceedings will have a material adverse effect on the Company’s financial position, results of operations or cash flows. 

13.    Restructuring

In an effort to align company resources with the overall market shift towards discrete filters, during the fourth quarter of 2013, management approved a voluntary severance plan at its Hillsboro, Oregon facility, other targeted reductions in force at various locations, and the closure of its engineering and test facility in Santa Rosa, CA. These activities were substantially completed by the end of the fourth quarter of 2013. During the first quarter of 2014, management approved, and substantially completed, additional targeted reductions in force. Expenses incurred as a result of these activities primarily consisted of severance related costs, which were reflected in the Company's statement of operations for the six months ended June 28, 2014 as follows:

13

Cost of goods sold	$	696
Research, development and engineering	955
Selling, general and administrative	71
Total restructuring charges	$	1,722

Changes in the Company's restructuring liability during the six months end June 28, 2014 were as follows:

	Severance			Lease abandonment costs			Total
Balance at December 31, 2013	$	2,421		$	495		$	2,916
2014 restructuring charges	1,683			39			1,722
Payments	(3,647		)	(200		)	(3,847		)
Balance at June 28, 2014	$	457		$	334		$	791

Overview

TriQuint Semiconductor, Inc. provides a comprehensive portfolio of advanced, high-performance radio frequency ("RF") solutions. We are a high-volume supplier of both active and passive technologies. We design, develop and manufacture high-performance power amplifier, switch and filter modules in-house and provide them to the broad market, uniquely integrating many of the world's most advanced RF solutions to deliver solid customer value. We have built core competencies in gallium arsenide ("GaAs"), gallium nitride ("GaN"), surface acoustic wave ("SAW") and bulk acoustic wave ("BAW") technologies. We reach further, with solutions that boost performance and extend range while reducing size and bill of materials. We reach faster, utilizing our broad technology portfolio to simplify complex RF challenges and allow our customers better time to market.

We serve customers worldwide in three primary end markets: mobile devices, networks, and defense & aerospace. Our mission is to deliver RF solutions that improve performance and lower the overall cost of our customers' applications. Our strategies to achieve this mission are to drive innovation and integration, ensure we serve a complementary and diverse set of markets, achieve scale through targeted growth and continue to offer a diversified product portfolio to customers in our primary end markets. In the mobile devices end market, we provide high performance devices such as integrated modules, SAW and BAW filter components, duplexers, small signal components, power amplifiers and switches. In the networks end market, we are a supplier of an extensive portfolio of GaAs microwave monolithic integrated circuits and transistors. We provide the defense & aerospace end market with phased-array radar, communications and electronic warfare components and have been recognized as a leader in GaN development.

Wafer and semiconductor manufacturing facilities require a significant level of fixed costs due to investments in plant and equipment, labor costs and repair and maintenance costs. During periods of high demand, factories run at higher utilization rates, generally resulting in improved financial performance. As the overall RF market has grown in recent years, with content expansion in smartphones, demand increased for our products. In response, we increased capital expenditures in order to add

15

capacity to our factories. We have utilized this increased capacity to fulfill customer demand for our high value premium filter products, which has positively impacted our operating results.

Highlights for the Six Months Ended June 28, 2014

Revenue increased 9% for the six months ended June 28, 2014 compared to the six months ended June 29, 2013.

Mobile devices represents the largest of our three major end markets. Revenue from the sales of our products in the mobile devices end market for the six months ended June 28, 2014 increased 11% compared to the six months ended June 29, 2013. The increase was primarily due to an increase in sales of premium filters. We believe our investments in premium filters, wafer level packaging and copper flip, will continue to drive solutions to our customers' problems with crowded spectrum and constrained board space as long term evolution ("LTE") demand increases.

Revenue from sales of our products in the networks end market increased 15% for the six months ended June 28, 2014 compared to the six months ended June 29, 2013. This increase was attributed to sales of our base station products in support of the time division LTE ("TD-LTE") build out in China, partially offset by decreased revenue from the sales of our multi market products, while sales of our transport products remained essentially flat. Growth in data traffic, in the form of streaming video, location services, machine to machine communications and social networking continues to drive infrastructure changes worldwide. TriQuint products support the continuing evolution of new frequency spectrum allocations, relieve the issues caused by spectrum interference and enable higher throughput networks.

Revenue from sales of our products in the defense & aerospace end market decreased 9% for the six months ended June 28, 2014 compared to the six months ended June 29, 2013 due to program timing, which can result in swings from quarter to quarter. With the current uncertainty over federal defense budgets, we are seeing some delays in spending from our customers. Overall, however, we are in a strong position on the programs we support, such as the Joint Strike Fighter, TPQ-53 and radar upgrade programs targeting the large domestic and international fleets of F-16 and F/A18 fighter aircraft, but budget uncertainty limits our timing visibility. We continue to accelerate the release of new products to support this market.

Plan of Merger and Reorganization

On February 22, 2014, TriQuint and RF Micro Devices, Inc. (“RFMD”) entered into an Agreement and Plan of Merger and Reorganization pursuant to which TriQuint and RFMD agreed, on the terms and subject to the conditions of the merger agreement, to effect a strategic combination of their respective businesses through a “merger of equals” business combination transaction. At the closing of the transaction, TriQuint and RFMD will each become a wholly owned subsidiary of a newly formed holding company, currently named Rocky Holding, Inc. This holding company has applied to list its common stock on the NASDAQ Global Select Market, subject to official notice of issuance. Prior to completion of the mergers, we anticipate that Rocky Holding, Inc. will change its name, adopt a NASDAQ symbol for its common stock, and register a new trade name and logo that reflect the key attributes of the combined company. Current RFMD Chief Executive Officer Robert A. Bruggeworth will serve as President and Chief Executive Officer of the combined company and current TriQuint Chief Executive Officer Ralph G. Quinsey will serve as the non-executive Chairman of the Board of Directors. The combined company’s board will consist of ten directors, with five directors from the existing boards of each company, and eight of the ten directors will be independent.

On July 15, 2014, TriQuint and RFMD amended the merger agreement in order to revise certain equity compensation plan provisions and to reflect the requirement that TriQuint stockholders separately approve the absence of a majority voting provision from Rocky Holding, Inc.’s certificate of incorporation, including making the completion of the business combination contingent upon the approval of such stockholder proposal.

Pursuant to the terms of the merger agreement, and upon completion of the mergers, TriQuint stockholders will receive 0.4187 of a share of common stock of the new holding company for each share of TriQuint common stock, and RFMD shareholders will receive 0.2500 of a share of common stock of the new holding company for each share of RFMD common stock. We anticipate that TriQuint stockholders and RFMD shareholders will each hold approximately 50% of the shares of common stock of the new holding company issued and outstanding immediately after completion of the mergers.

Critical Accounting Policies and Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires us to make certain estimates, judgments and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Some of our accounting policies require us to make difficult and subjective judgments, often as a result of the need to make estimates of matters that are inherently uncertain. The accounting policies

16

involve critical accounting estimates because they are particularly dependent on estimates and assumptions made by management about matters that are highly uncertain at the time the accounting estimates are made. Although we have used our best estimates based on facts and circumstances available to us at the time, different estimates reasonably could have been used. Changes in the accounting estimates we use are reasonably likely to occur from time to time, which may have a material effect on the presentation of our financial condition and results of operations.

Our most critical accounting estimates include revenue recognition; valuation of inventory, which affects gross margin; accounting for income taxes; precious metals reclaim, which affects cost of goods sold; and stock-based compensation, which affects cost of goods sold and operating expenses. We also have other policies that we consider to be key accounting policies, such as the valuation of accounts receivable and reserves for sales returns and allowances; however, these policies either do not meet the definition of critical accounting estimates described above or are not currently material items in our financial statements. We review our estimates, judgments, and assumptions periodically and reflect the effects of revisions in the period in which they are deemed to be necessary. We believe that these estimates are reasonable; however, actual results could differ from these estimates. For further discussion of our critical accounting policies and estimates, see Management's Discussion and Analysis of Financial Condition and Results of Operations-Critical Accounting Policies and Estimates contained in our Annual Report on Form 10-K for the year ended December 31, 2013.

Three Months Ended June 28, 2014 and June 29, 2013

Revenue from Operations

Revenue increased $40.7 million, or 21%, for the three months ended June 28, 2014 compared to the three months ended June 29, 2013.

Revenue by end market for the three months ended June 28, 2014 and June 29, 2013, was as follows:

17

(in millions)	Three Months Ended
	June 28, 2014		June 29, 2013
Mobile Devices	$	144.4	$	117.9
Networks	60.0		45.5
Defense & Aerospace	26.4		26.7
Total	$	230.8	$	190.1

Mobile Devices

Revenue from the sales of our products in the mobile devices end market increased approximately 22% for the three months ended June 28, 2014 compared to the three months ended June 29, 2013 primarily as a result of increased revenue from sales of our 4G/LTE products, partially offset by decreased revenue from our 3G/2G and wireless local area networks ("WLAN") products. We expect the combination of crowded spectrum, carrier aggregation, and expanding LTE adoption will continue to drive growth in our 4G/LTE end market. Revenue from the sales of our products in the three primary submarkets of the mobile devices end market was as follows:

(in millions)	Three Months Ended
	June 28, 2014		June 29, 2013
4G/LTE	$	91.8	$	4.8
3G/2G	38.2		81.3
WLAN	14.4		31.8
Total	$	144.4	$	117.9

Networks

Revenue from the sales of our products in the networks end market increased approximately 32% for the three months ended June 28, 2014 compared to the three months ended June 29, 2013. The increase was primarily due to increased sales of our base station and transport products, partially offset by decreased revenue from the sales of our multi market products. Revenue from the sales of our products in the three primary submarkets of the networks end market was as follows:

(in millions)	Three Months Ended
	June 28, 2014		June 29, 2013
Base Station	$	25.2	$	14.2
Transport	27.9		21.8
Multi-market	6.9		9.5
Total	$	60.0	$	45.5

Defense & Aerospace

Revenue from the sales of our products in the defense & aerospace end market decreased approximately 1% for the three months ended June 28, 2014 compared to the three months ended June 29, 2013, primarily as a result of the timing of programs.

Significant Customers

For the three months ended June 28, 2014 and June 29, 2013, sales to Foxconn Technology Group accounted for 25% and 22% of our revenue, respectively. For the three months ended June 28, 2014, sales to Huawei accounted for 11% of our revenue. Our customers' product life cycles typically are short because they continually develop new products. The selection process for our products to be included in our customers' new products is highly competitive. While we strive to maintain a strong relationship with our customers, there are no guarantees that our products will be included in the next generation of products introduced by Foxconn Technology Group, Huawei, or our other customers. Any significant loss of, or a significant reduction in purchases by, these or other significant customers, could have an adverse effect on our financial condition and results of operations.

18

Some of our mobile devices end customers use multiple subcontractors for product assembly and test and some of those subcontractors have multiple customers. Therefore, revenues from our customers may not necessarily equal the business of a single mobile devices end customer.

Gross Profit

Our gross profit as a percentage of revenue increased to 40.2% for the three months ended June 28, 2014, from 29.8% for the three months ended June 29, 2013. The increase in gross profit was primarily the result growth in our premium filter business, higher revenues, efficient factory management and cost reduction efforts.

Operating expenses

Research, development and engineering

Our research, development and engineering expenses for the three months ended June 28, 2014 increased $0.9 million, or 2%, compared to the three months ended June 29, 2013. The increase was primarily the result of increased spending on material to develop new products.

Selling, general and administrative

Selling, general and administrative expenses for the three months ended June 28, 2014 increased $11.3 million, or 44%, compared to the three months ended June 29, 2013. The increase was primarily the result of higher professional fees associated with the proposed merger with RFMD.

Other expense, net

Other expense, net for the three months ended June 28, 2014 compared to the three months ended June 29, 2013 increased $0.7 million, or 87%, primarily due to the impairment of equity investments.

Income tax expense (benefit)

We recorded an income tax expense (benefit) of $0.8 million and $(2.3) million for the three months ended June 28, 2014 and June 29, 2013, respectively. The income tax expense for the three months ended June 28, 2014 was primarily the result of our pre-tax earnings offset by the recognition of stock-based compensation tax deductions related to disqualifying dispositions on exercises in the quarter. The income tax benefit for the three months ended June 29, 2013 was primarily the result of our pre-tax loss and the recognition of U.S. federal tax credits.

Six Months Ended June 28, 2014 and June 29, 2013

Revenue from Operations

Revenue increased $34.1 million, or 9%, for the six months ended June 28, 2014 compared to the six months ended June 29, 2013.

Revenue by end market for the six months ended June 28, 2014 and June 29, 2013, was as follows:

(in millions)	Six Months Ended
	June 28, 2014		June 29, 2013
Mobile Devices	$	247.6	$	223.4
Networks	111.6		96.7
Defense & Aerospace	49.2		54.2
Total	$	408.4	$	374.3

Mobile Devices

Revenue from the sales of our products in the mobile devices end market increased approximately 11% for the six months ended June 28, 2014 compared to the six months ended June 29, 2013 primarily as a result of increased revenue from sales of our 4G/LTE products, partially offset by decreased revenue from our 3G/2G and WLAN products. Revenue from the sales of our products in the three primary submarkets of the mobile devices end market was as follows:

19

(in millions)	Six Months Ended
	June 28, 2014		June 29, 2013
4G/LTE	$	152.2	$	8.4
3G/2G	73.3		164.9
WLAN	22.1		50.1
Total	$	247.6	$	223.4

Networks

Revenue from the sales of our products in the networks end market increased approximately 15% for the six months ended June 28, 2014 compared to the six months ended June 29, 2013. The increase was primarily due to increased sales of our base station products, partially offset by decreased revenue from the sales of our multi market products, while sales of our transport products remained essentially flat. Revenue from the sales of our products in the three primary submarkets of the networks end market was as follows:

(in millions)	Six Months Ended
	June 28, 2014		June 29, 2013
Base Station	$	51.3	$	33.1
Transport	46.5		46.7
Multi-market	13.8		16.9
Total	$	111.6	$	96.7

Defense & Aerospace

Revenue from the sales of our products in the defense & aerospace end market decreased approximately 9% for the six months ended June 28, 2014 compared to the six months ended June 29, 2013, primarily due primarily to the timing of programs.

Significant Customers

For the six months ended June 28, 2014 and June 29, 2013, sales to Foxconn Technology Group accounted for 25% and 23% of our revenue, respectively. For the six months ended June 28, 2014, sales to Huawei accounted for 10% of our revenue.

Gross Profit

Our gross profit as a percentage of revenue increased to 37.2% for the six months ended June 28, 2014, from 25.5% for the six months ended June 29, 2013. The increase in gross profit was primarily the result of better product mix, higher revenues, efficient factory management and cost reduction efforts.

Operating expenses

Research, development and engineering

Our research, development and engineering expenses for the six months ended June 28, 2014 increased $4.7 million, or 5%, compared to the six months ended June 29, 2013. The increase was primarily the result of higher payroll taxes attributed to an increase in stock option exercises, increased spending on material to develop new products and severance costs associated with our restructuring plans.

Selling, general and administrative

Selling, general and administrative expenses for the six months ended June 28, 2014 increased $13.2 million, or 25%, compared to the six months ended June 29, 2013. The increase was primarily the result of higher professional fees associated with the proposed merger with RFMD.

Other expense, net

Other expense, net was relatively flat for the six months ended June 28, 2014 compared to the six months ended June 29, 2013 with an increase of less than $0.1 million.

Income tax benefit

20

We recorded an income tax benefit of $0.9 million and $10.3 million for the six months ended June 28, 2014 and June 29, 2013, respectively. The income tax benefit for the six months ended June 28, 2014 was primarily the result of the recognition of stock-based compensation tax deductions related to disqualifying dispositions on exercises in the quarter. The income tax benefit for the six months ended June 29, 2013 was primarily the result of our pre-tax loss and the recognition of U.S. federal tax credits.

Liquidity and Capital Resources

Liquidity

As of June 28, 2014, our cash, cash equivalents and short-term marketable securities increased $144.5 million, or 183%, from December 31, 2013, primarily a result of:

• a decrease in our accounts receivable balance of $35.4 million, or 20%, primarily due to collections associated with higher sales volumes near the end of the last fiscal year compared to the three months ended June 28, 2014,

• a net decrease of $5.3 million, or 1.2%, in property, plant and equipment driven by depreciation of $48.8 million, which outpaced capital expenditures of $43.0 million for the six months ended June 28, 2014,

• an increase on our trade payable and accrued expense balances of $8.9 million primarily due to increased purchasing activity in anticipation of a production ramp up in the third quarter of 2014, and

• proceeds from the subscription/issuance of common stock of $76.5 million primarily attributed to stock options exercised by employees.

Sources of Liquidity

Our current cash, cash equivalents and short-term investments balances, together with cash anticipated to be generated from operations and the balance available on our $200 million syndicated credit facility, constitute our principal sources of liquidity. We believe these sources will satisfy our projected expenditures through the next twelve months. We intend to permanently reinvest all foreign earnings except for those of liquidating foreign entities and existing earnings that have been previously taxed. As of June 28, 2014, cash and short-term investments held by our foreign entities amounted to $44.5 million. Management intends to utilize this balance to satisfy intercompany trade activity between our foreign entities and the U.S. company, which is entered into through the normal course of business, and not subject to additional U.S. income taxes or foreign withholding taxes. At this time, we believe our domestic funds, along with the syndicated credit facility, are sufficient to meet our net domestic cash requirements for the next twelve months. The principal risks to these sources of liquidity are lower than expected earnings or capital expenditure requirements in excess of our expectations.

As of June 28, 2014, we had approximately $4.0 million of net unrecognized tax benefits, which are included in Long-term income tax liability on our consolidated balance sheets. We do not anticipate that settlement of the liabilities will require payment of cash within the next twelve months. Further, we are not able to reasonably estimate the timing of any cash payments required to settle these liabilities and do not believe that the ultimate settlement of these obligations will materially affect our liquidity.

Off Balance Sheet Arrangements

As of June 28, 2014, we did not have any off balance sheet arrangements, as defined in Regulation S-K Item 303(a)(4), except for operating leases for various facilities. We did not have any relationships with unconsolidated entities or financial partnerships such as entities often referred to as structured finance or special purpose entities, which would have been established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes. As such, we are not exposed to any financing, liquidity, market or credit risk that could arise if we had engaged in such relationships.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

Our investments in cash equivalents are classified as available-for-sale securities and consist of highly-rated, short-term investments, such as money market funds, in accordance with an investment policy approved by our Board of Directors. All of these investments are held at fair value. We do not hold or issue derivatives, derivative commodity instruments or other financial instruments for speculative trading purposes. The following table shows the fair value of our cash and investments as of June 28, 2014 (in millions):

21

	Cost		Fair Value
Cash and cash equivalents	$	214.5	$	214.5
Short-term available-for-sale investments (including net unrealized losses of less than $0.1)	$	9.0	$	9.0
Long-term investments in marketable securities	$	1.0	$	1.0

Foreign Currency Risk

We are exposed to currency exchange rate fluctuations because we sell our products internationally and have operations in Singapore, Costa Rica and Germany. We manage the foreign currency risk of our international sales and purchases of raw materials and equipment by denominating most transactions in U.S. dollars.

Item 4. Controls and Procedures

Evaluation of disclosure controls and procedures. We conducted an evaluation (pursuant to Rule 13a-15(b) of the Securities Exchange Act of 1934 (the “Exchange Act”)), under the supervision of and with the participation of management, including our chief executive officer and chief financial officer, of the effectiveness of our disclosure controls and procedures (as defined in Rule 13a-15(e)) as of the end of the period covered by this Quarterly Report on Form 10-Q. These disclosure controls and procedures are designed to ensure that information required to be disclosed in our reports that are filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms. Our disclosure controls and procedures include controls and procedures designed to ensure that this information is accumulated and communicated to management, including the principal executive and principal financial officers, or persons performing similar functions, as appropriate, to allow timely decisions regarding required disclosure. Based on this evaluation, our chief executive officer and chief financial officer have concluded that our disclosure controls and procedures were effective as of the end of the period covered by this Quarterly Report on Form 10-Q.

Changes in internal control over financial reporting. There was no change in our internal control over financial reporting (as defined in Rule 13a-15(f) of the Exchange Act) that occurred during the period covered by this Quarterly Report on Form 10-Q that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Investments in Cash Equivalents and Marketable Securities

Investments in Cash Equivalents and Marketable Securities

As of June 28, 2014 and December 31, 2013, cash equivalents and short-term investments were classified as available-for-sale. Cash equivalents had maturity dates of less than 90 days at the date acquired, and short-term investments had maturity dates of less than one year, from the date of purchase. All unrealized gains and losses on available-for-sale investments are included in Other comprehensive income (loss). The cost, net unrealized holding gains, net unrealized holding losses and fair value of available-for-sale investments by types and classes of security at June 28, 2014 consisted of the following:

Investments are considered to be impaired when a decline in fair value is judged to be other-than-temporary. The Company employs a methodology that reviews specific securities in evaluating potential impairment of its investments. In the event that the cost of an investment exceeds its fair value, the Company evaluates, among other factors, the Company’s intent and ability to hold the investment and extent to which the fair value is less than cost; the financial health of and business outlook for the issuer; and operating and financing cash flow factors. During the three and six months ended June 28, 2014, the Company did not record any other-than-temporary impairments on its investments in cash equivalents.

Fair Value Disclosures [Abstract]

Fair Value of Financial Instruments

Fair Value of Financial Instruments

The Company accounts for its assets utilizing a hierarchy of valuation techniques based on whether the inputs to those valuation techniques are observable or unobservable. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect the Company’s market assumptions. These two types of inputs have created the following fair-value hierarchy:

• Level 1—Quoted prices for identical instruments in active markets;

• Level 2—Quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets; and

• Level 3—Valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable.

Assets and liabilities measured and recorded at fair value on a recurring basis at June 28, 2014 are as follows:

There were no transfers between Level 1, Level 2 or Level 3 fair value measurements during the three or six months ended June 28, 2014 and June 29, 2013.

The Company's non-qualified deferred compensation plan provides eligible employees and members of the Board of Directors with the opportunity to defer a specified percentage of their cash compensation. The Company includes the asset deferred by the participants in Other noncurrent assets, net on its consolidated balance sheets and the Company’s obligation to deliver the deferred compensation in Other long-term liabilities on its consolidated balance sheets.

The Company's earnout and milestone payment liability as of June 28, 2014 resulted from two acquisitions during 2012 and represents the fair value of the estimated payout to the former businesses contingent upon meeting certain requirements. For the first acquisition, as of June 28, 2014, the Company estimated the fair value of the obligation as $584 using a cash flow based approach discounted with a market discount rate. For the second acquisition, as of June 28, 2014, the Company estimated the fair value of the obligation as $1,482 using a Monte Carlo simulation model discounted using the risk free rate adjusted for an applicable credit spread. During the six months ended June 28, 2014, the Company remeasured the fair value of its obligations based on a change in forecast related to the achievement of earnout targets. The change in estimate resulted in a decrease to the liability of $279 in aggregate and was recorded to selling, general and administrative expenses in the statement of operations. For both of the acquisitions, total accretion of $445 was recognized during the six months ended June 28, 2014.

Financial Instruments Not Recorded at Fair Value on a Recurring Basis

The Company entered into two separate cross-licensing agreements, one in 2012 and another in the first quarter of 2014. The fair value of the first cross-licensing agreement was estimated using a discounted cash flow model which discounted the future cash flows using an incremental borrowing rate of 9%. The fair value of the second cross-licensing agreement was estimated using a discounted cash flow model which discounted the future cash flows using an incremental borrowing rate of 5%. These cross-licensing liabilities are categorized as Level 3 in the fair-value hierarchy and the ending fair value at June 28, 2014 was $14,144, of which $2,540 was current and is included in other accrued liabilities on the consolidated balance sheets.

Basis of Presentation

The accompanying condensed consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States (“GAAP”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed, or omitted, pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). In addition, the preparation of financial statements in conformity with GAAP requires management to make estimates and judgments that affect the amounts reported in the financial statements and accompanying notes. For TriQuint Semiconductor, Inc. (the “Company”), the accounting estimates requiring management’s most difficult and subjective judgments include revenue recognition, the valuation of inventory, the accounting for income taxes, precious metals reclaim and stock-based compensation. Certain reclassifications have been made to prior year balances in order to conform to the current year presentation. In the opinion of management, the condensed consolidated financial statements include all material adjustments, consisting only of normal, recurring adjustments, necessary for the fair presentation of the results of the interim periods presented. These condensed consolidated financial statements should be read in conjunction with the audited financial statements of the Company as of and for the fiscal year ended December 31, 2013, included in the Company’s 2013 Annual Report on Form 10-K filed with the SEC on February 21, 2014.

Description of New Accounting Pronouncements Not yet Adopted [Text Block]

Recent Accounting Pronouncements

On May 28, 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers, which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The ASU will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. The new standard is effective for the Company on January 1, 2017. Early application is not permitted. The standard permits the use of either the retrospective or cumulative effect transition method. The Company is evaluating the effect that ASU 2014-09 will have on its consolidated financial statements and related disclosures. The Company has not yet selected a transition method nor has it determined the effect of the standard on its ongoing financial reporting.

Legal Matters

The Company is from time to time involved in litigation, certain other claims and arbitration matters arising in the ordinary course of its business. In addition, since the public announcement of the proposed business combination with RF Micro Devices, Inc. (“RFMD”) on February 24, 2014, five putative stockholder class action lawsuits have been filed against the Company, its directors, RFMD, and others in connection with the proposed mergers. Two of the five actions were filed in the Multnomah County Circuit Court in the State of Oregon: (1) Roberts vs. TriQuint Semiconductor, Inc. et al., Case No. 1402-02441, filed on February 28, 2014; and (2) Lam v. Steven J. Sharp et al., Case No. 1403-02757, filed on March 6, 2014. The other three actions were filed in the Court of Chancery of the State of Delaware: (1) Philemon v. TriQuint Semiconductor, Inc. et al., Case No. 9415-VCN, filed on March 5, 2014; (2) Schmitz v. TriQuint Semiconductor, Inc. et al., Case No. 9427-VCN, filed on March 7, 2014; and (3) Wallace v. TriQuint Semiconductor, Inc. et al., Case No. 9429-VCN, filed on March 10, 2014. Each of these lawsuits was filed on behalf of a putative class of the Company’s stockholders against the Company, the individual members of the Company’s board of directors, RFMD, Rocky Holding, Inc., and/or the to-be-formed subsidiaries of Rocky Holding, Inc. that will be used to effect the mergers. The plaintiffs in each of these lawsuits generally seek, among other things, declaratory and injunctive relief concerning alleged breaches of fiduciary duties, injunctive relief prohibiting completion of the mergers, rescission of the mergers if they are completed, an accounting by defendants, rescissionary damages, attorney’s fees and costs, and other relief. TriQuint moved to dismiss the Roberts and Lam actions filed in Oregon. Those motions to dismiss have been fully briefed and argued and are under advisement with the court. On April 29, 2014, the court orally granted the plaintiffs’ motions to consolidate the Oregon actions. On April 29, 2014, the Delaware Court of Chancery consolidated the actions filed in Delaware under the caption In re TriQuint Semiconductor, Inc. Stockholders Litigation, C.A. No. 9415-VCN. On May 1, 2014, the plaintiffs filed a consolidated amended class action complaint in the consolidated action and on May 12, 2014, the plaintiffs filed a motion for expedited proceedings and a motion for preliminary injunction seeking to enjoin defendants from taking any action to complete the proposed mergers. TriQuint opposed the motion for expedited proceedings, and the court denied the motion for expedited proceedings on June 13, 2014.

The Company believes the lawsuits to be without merit and intends to defend the lawsuits vigorously. The Company does not believe the ultimate resolution of any such pending proceedings will have a material adverse effect on the Company’s financial position, results of operations or cash flows.

Restructuring

In an effort to align company resources with the overall market shift towards discrete filters, during the fourth quarter of 2013, management approved a voluntary severance plan at its Hillsboro, Oregon facility, other targeted reductions in force at various locations, and the closure of its engineering and test facility in Santa Rosa, CA. These activities were substantially completed by the end of the fourth quarter of 2013. During the first quarter of 2014, management approved, and substantially completed, additional targeted reductions in force. Expenses incurred as a result of these activities primarily consisted of severance related costs, which were reflected in the Company's statement of operations for the six months ended June 28, 2014 as follows:

Cost of goods sold	$	696
Research, development and engineering	955
Selling, general and administrative	71
Total restructuring charges	$	1,722

Changes in the Company's restructuring liability during the six months end June 28, 2014 were as follows:

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Income Tax Uncertainties, Policy [Policy Text Block]

The Company records a valuation allowance to reduce deferred tax assets to the amount that is believed more-likely-than-not to be realized. The Company maintains a valuation allowance against the tax effect of all capital loss carryforwards, certain state and foreign net operating loss carryforwards, and certain state credit carryforwards, as management does not believe it is more likely than not that these benefits will be realized in future periods.

Use of Estimates

In addition, the preparation of financial statements in conformity with GAAP requires management to make estimates and judgments that affect the amounts reported in the financial statements and accompanying notes. For TriQuint Semiconductor, Inc. (the “Company”), the accounting estimates requiring management’s most difficult and subjective judgments include revenue recognition, the valuation of inventory, the accounting for income taxes, precious metals reclaim and stock-based compensation.

Fair Value Policy

The Company accounts for its assets utilizing a hierarchy of valuation techniques based on whether the inputs to those valuation techniques are observable or unobservable. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect the Company’s market assumptions. These two types of inputs have created the following fair-value hierarchy:

• Level 1—Quoted prices for identical instruments in active markets;

• Level 2—Quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets; and

• Level 3—Valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable.

Marketable Securities Policy

All unrealized gains and losses on available-for-sale investments are included in Other comprehensive income (loss).

Earnings Per Share Policy

Net Earnings (Loss) Per Share

Net earnings (loss) per share is presented as basic and diluted net earnings (loss) per share. Basic net earnings (loss) per share is net earnings (loss) available to common stockholders divided by the weighted-average number of common shares outstanding. Diluted net earnings per share is similar to basic net earnings (loss) per share, except that the denominator includes potential common shares that, had they been issued, would have had a dilutive effect. Dilutive securities include options granted pursuant to the Company’s stock option plans, and potential shares related to Restricted Stock Units ("RSUs"), Market-Based Restricted Stock Units ("MSUs") and the Company’s Employee Stock Purchase Plan ("ESPP").

Amortization of Loan Fees

The initial fees associated with the Agreement were capitalized and are being amortized to interest expense using the straight-line method over the remaining term to maturity.

Goodwill and Intangible Assets, Policy

The Company is required to perform an impairment analysis on its goodwill at least annually, or when events and circumstances warrant. Conditions that would trigger an impairment assessment, include, but are not limited to, a significant adverse change in legal factors or in the business climate that could affect the value of an asset or an adverse action or assessment by a regulator. The Company is considered one reporting unit. When the Company performed this test in 2013, the Company elected to use the two-step goodwill impairment test. Therefore, to determine whether goodwill may be impaired, the Company compares its book value to its market capitalization. If the trading price of the Company’s common stock, as adjusted for factors such as a control premium, is below the book value per share at the date of the annual impairment test or if the average trading price of the Company’s common stock is below book value per share for a sustained period, a goodwill impairment test will be performed by comparing book value to estimated market value. If the comparison of book value to estimated market value indicates impairment, then the Company compares the estimated market value of goodwill to its carrying amount in a manner similar to a purchase price allocation for a business combination. If the carrying amount of goodwill exceeds its estimated market value, an impairment loss is recognized equal to that excess.

Unless indicators warrant testing at an earlier date, the Company performs its annual goodwill impairment test in the fourth quarter of each year. During the six months ended June 28, 2014, there were no impairments recorded.

Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block]

Restricted Stock Units and Market Based Restricted Stock Units

RSUs are converted into shares of Company common stock upon vesting on a one-for-one basis. The awards typically vest over four years and vesting is subject to the grantee’s continued service with the Company. The compensation expense related to the service-based RSU awards is determined using the fair market value of Company common stock on the date of the grant, and the compensation expense, reduced by estimated forfeitures, is recognized over the vesting period.

The Company grants MSUs to certain members of executive management. The number of shares that are ultimately awarded is contingent upon the achievement of pre-determined market and service conditions. Market conditions must be met for shares to be awarded, even if the service conditions are met. Fair value of the awards is determined at the grant date based on the target number of awards ultimately expected to be awarded. Compensation expense associated with the awards is calculated based on the target number of shares ultimately expected to be awarded and is recognized on a straight line basis over the requisite service period and will not be reversed even if the market conditions are not met. The number of shares of common stock to be awarded will range from zero to 150 percent of the target number of stock units based on the Company's total stockholder return (“TSR”) relative to the performance of companies in the SPDR S&P Semiconductor Index ("SPDR") for the applicable measurement period. TSR is calculated based on market performance between the beginning and end of the award period, generally over three years. Based on the number of awards outstanding as of June 28, 2014, the maximum number of shares of common stock that could be awarded is 514 shares.

The fair value of the MSUs was determined using a Monte Carlo simulation model. The Monte Carlo simulation model is affected by assumptions regarding subjective and complex variables. Generally, the Company's assumptions are based on historical information and judgment is required to determine if historical trends may be indicators of future outcomes.

The Company abandoned and wrote off $213 relating to one product line that was included in in-process research and development during the three months ended June 28, 2014. The Company abandoned and wrote off $425 relating to two product lines that were included in in-process research and development during the six months ended June 28, 2014. These charges were recorded to research, development and engineering expense in the statement of operations. There were no similar charges during the three or six months ended June 29, 2013.

During the three and six months ended June 28, 2014, one product line that was included in in-process research and development reached technological feasibility. As a result, the Company transferred $212 to developed technology, and began amortizing this amount over a period of eight years. There were no similar transfers during the three or six months ended June 29, 2013.

The Company acquired developed technology of $375 and patents of $150 during the three and six months ended June 28, 2014, that will be amortized over a period of eight years and seventeen years, respectively. There were no similar acquisitions during the three or six months ended June 29, 2013.

Line of Credit Facility [Abstract]

Credit Facility

Credit Facility

On September 30, 2010, the Company, the domestic subsidiaries of the Company (the “Guarantors”), Bank of America, N.A., as administrative agent and lender, and Union Bank, N.A., Wells Fargo Bank, N.A., Bank of the West, BBVA Compass Bank and US Bank, as lenders (together with the administrative agent, the “Lenders”), entered into a Credit Agreement (the “Agreement”). The Agreement provided the Company with a three-year unsecured revolving syndicated credit facility of $200,000 maturing on September 30, 2013. On August 24, 2011, the Company extended, with the Lenders' consent, the maturity date to September 30, 2014. The Company’s obligations under the Agreement are jointly and severally guaranteed by the Guarantors. Upon the occurrence of events of default specified in the Agreement, amounts due under the Agreement may be declared immediately due and payable.

The Company may elect to borrow at either a Eurodollar Rate or a Base Rate (each as defined in the Agreement). Eurodollar Rate loans bear interest at an amount equal to the sum of a rate per annum calculated from the British Bankers Association London Interbank Offered Rate ("LIBOR") plus a designated percentage per annum (the “Applicable Rate”). The Applicable Rate for Eurodollar Rate loans is based on the Company’s consolidated total leverage ratio (as defined in the Agreement) and is subject to a floor of 2.50% per annum and a cap of 3.00% per annum. Base Rate loans bear interest at a rate equal to the higher of the federal funds rate plus 0.50%, the prime rate of Bank of America, N.A. plus the Applicable Rate or the Eurodollar Base Rate plus 1.0%. The Applicable Rate for Base Rate loans is subject to a floor of 1.50% per annum and a cap of 2.00% per annum. The interest payment date (as defined in the Agreement) will vary based on the type of loan but generally will be quarterly. The Company paid commitment fees, an arrangement fee, upfront fees and a renewal fee pursuant to the terms of the Agreement. The Company will also pay a quarterly fee for any letters of credit issued under the Agreement. The initial fees associated with the Agreement were capitalized and are being amortized to interest expense using the straight-line method over the remaining term to maturity.

The Agreement contains non-financial covenants of the Company and the Guarantors, including restrictions on the ability to create, incur or assume liens and other debt, make certain investments, dispositions and restricted payments, change the nature of the business, and merge with other entities subject to certain caps as defined in the agreement. The Agreement requires the Company to maintain ratios defined in the Agreement, which include a consolidated total leverage ratio as of the end of any fiscal quarter not in excess of 2.50 to 1.00, a consolidated liquidity ratio of at least 1.25 to 1.00 and a consolidated interest coverage ratio at a minimum of 3.00 to 1.00. The Company was in compliance with these covenants as of June 28, 2014.

At June 28, 2014 and December 31, 2013, there were no amounts outstanding under the Agreement. Because there were no borrowings during the three and six months ended June 28, 2014, no interest cost was incurred on borrowings during this time. During the three and six months ended June 29, 2013, interest cost of $3 was incurred on borrowings.

Income Taxes

Income Taxes

The Company recorded income tax expense (benefit) of $761 and $(2,255) for the three months ended June 28, 2014 and June 29, 2013, respectively. The Company recorded income tax (benefit) of $(936) and ($10,256) for the six months ended June 28, 2014 and June 29, 2013, respectively. The income tax expense for the three months ended June 28, 2014 was primarily the result of the Company's pre-tax income, offset by the recognition of stock-based compensation tax deductions related to disqualifying dispositions on exercises in the quarter. The income tax benefit for the six months ended June 28, 2014 is primarily the result of the Company's recognition of stock-based compensation tax deductions related to disqualifying dispositions on exercises. The income tax benefit for the three and six months ended June 29, 2013 was primarily the result of the Company's pre-tax loss, and the recognition of U.S. federal tax credits.

As of June 28, 2014, the U.S. Congress had not extended the general business credit for research and experimentation. The Company has not estimated the effect of the expiration of this credit, nor does the income tax expense for the three and six months ended June 28, 2014 reflect a benefit for the credit.

No provision has been made for the U.S., state or additional foreign income taxes related to approximately $70,500 of undistributed earnings of foreign subsidiaries which have been permanently reinvested outside the U.S. except for existing earnings that have been previously taxed. In the event of repatriation, which would generally require board approval, the earnings may be subject to an estimated $25,000 of U.S. federal and state income taxes and foreign withholding taxes.

The major jurisdictions in which the Company files tax returns are the United States, Singapore and Costa Rica. In 2012, the Company expanded its presence into Asia by increasing operations in Singapore. Due to agreements with the Costa Rican and Singaporean governments, the Company was granted income tax holidays of varying rates through March 2017 and December 2019, respectively. Incentives from these countries are subject to the Company meeting certain employment and investment requirements. The Company was in compliance with these requirements as of June 28, 2014.

Deferred Income Taxes

As of June 28, 2014, deferred tax assets of $77,661, net of a $16,243 valuation allowance, were recorded on the balance sheet. As of December 31, 2013, the Company had deferred tax assets of $74,341, net of a $16,639 valuation allowance. The Company records a valuation allowance to reduce deferred tax assets to the amount that is believed more-likely-than-not to be realized. The Company maintains a valuation allowance against the tax effect of all capital loss carryforwards, certain state and foreign net operating loss carryforwards, and certain state credit carryforwards, as management does not believe it is more likely than not that these benefits will be realized in future periods.

Unrecognized Tax Benefits

In the six months ended June 28, 2014, net unrecognized tax benefits increased $1,934 primarily as a result of an additional liability recorded to address existing potential exposures from positions that could be challenged by taxing authorities. Within the next 12 months, the Company believes it is reasonably possible that $1,460 of net unrecognized tax benefits may be reduced as a result of the expiration of a statute of limitations. Interest and penalties associated with unrecognized tax benefits are accrued and classified as a component of tax expense in the statement of operations and comprehensive loss.

Net unrecognized tax benefits at June 28, 2014 and December 31, 2013 were as follows:

	June 28, 2014		December 31, 2013
Net unrecognized tax benefits	$	3,996	$	2,062

Net Earnings (Loss) Per Share

Earnings Per Share [Abstract]

Net Earnings (Loss) Per Share

Net Earnings (Loss) Per Share

Net earnings (loss) per share is presented as basic and diluted net earnings (loss) per share. Basic net earnings (loss) per share is net earnings (loss) available to common stockholders divided by the weighted-average number of common shares outstanding. Diluted net earnings per share is similar to basic net earnings (loss) per share, except that the denominator includes potential common shares that, had they been issued, would have had a dilutive effect. Dilutive securities include options granted pursuant to the Company’s stock option plans, and potential shares related to Restricted Stock Units ("RSUs"), Market-Based Restricted Stock Units ("MSUs") and the Company’s Employee Stock Purchase Plan ("ESPP").

The following is a reconciliation of the basic and diluted shares:

	Three Months Ended					Six Months Ended
	June 28, 2014		June 29, 2013			June 28, 2014			June 29, 2013
Net income (loss):	$	5,210	$	(14,885	)	$	(13,859	)	$	(42,834	)
Shares for net income (loss) per share:
Weighted-average shares outstanding—Basic	171,770		159,347			168,140			160,044
Dilutive securities	9,549		—			—			—
Weighted-average shares outstanding—Diluted	181,319		159,347			168,140			160,044

For the three months ended June 28, 2014, no potential shares were excluded from the calculation. For the six months ended June 28, 2014 and the three and six months ended June 29, 2013, potential shares of 8,949, 4,024, and 3,216, respectively, related to RSUs, MSUs and the ESPP were excluded from the calculation as their effect would have been antidilutive.
