NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

A. The Company

Teradyne, Inc. (the “Company” or “Teradyne”) is a leading global supplier of automatic test equipment. Teradyne’s automatic test equipment products and services include:

| • |  | semiconductor test (“Semiconductor Test”) systems;

| • |  | wireless test (“Wireless Test”) systems; and

| • |  | military/aerospace (“Mil/Aero”) test instrumentation and systems, storage test (“Storage Test”) systems, and circuit-board test and inspection (“Commercial Board Test”) systems (collectively these products represent “Systems Test”).

B. Accounting Policies

Basis of Presentation

The condensed consolidated interim financial statements include the accounts of Teradyne and its wholly-owned subsidiaries. All significant intercompany balances and transactions have been eliminated. These interim financial statements are unaudited and reflect all normal recurring adjustments that are, in the opinion of management, necessary for the fair presentation of such interim financial statements. Certain prior year’s amounts were reclassified to conform to the current year presentation. The December 31, 2012 condensed consolidated balance sheet data was derived from audited financial statements, but does not include all disclosures required by accounting principles generally accepted in the United States of America.

The accompanying financial information should be read in conjunction with the consolidated financial statements and notes thereto contained in Teradyne’s Annual Report on Form 10-K, filed with the U.S. Security and Exchange Commission (“SEC”) on March 1, 2013, for the year ended December 31, 2012.

Preparation of Financial Statements and Use of Estimates

The preparation of consolidated financial statements requires management to make estimates and judgments that affect the amounts reported in the financial statements. Actual results may differ significantly from these estimates.

C. Recently Issued Accounting Pronouncements

In December 2011, the Financial Accounting Standards Board (FASB) issued Accounting Standard Update (ASU) No. 2011-11, “Disclosures about Offsetting Assets and Liabilities.” This ASU is intended to enhance the understanding of the effects of netting arrangements on an entity’s financial statements, including financial instruments and derivative instruments that are either offset or subject to a master netting arrangement. The scope of this ASU includes derivatives, sale and repurchase agreements, reverse sale and repurchase agreements, and securities borrowing and lending arrangements. The provisions of this ASU are effective for interim and annual periods beginning on or after January 1, 2013. Teradyne adopted this ASU effective January 1, 2013. See Note D “Financial Instruments and Derivatives.”

In February 2013, the FASB issued ASU 2013-02, “Comprehensive Income (Topic 220): Reporting of Amounts Reclassified out of Accumulated Other Comprehensive Income” amending the disclosure requirements regarding the reporting of amounts reclassified out of accumulated other comprehensive income. The amendment does not change the current requirement for reporting net income or other comprehensive income, but requires

##### Table of Contents

additional disclosures about significant amounts reclassified out of accumulated other comprehensive income including the effect of the reclassification on the related statement of operations line items. The provisions of this ASU are effective for interim and annual periods beginning on or after January 1, 2013. Teradyne adopted this amendment effective January 1, 2013. See Note I “Accumulated Other Comprehensive Income.”

On July 18, 2013, the FASB issued ASU 2013-11, “Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists.” Under this ASU, unrecognized tax benefits will be netted against all available same-jurisdiction loss or other tax carryforwards that would be utilized, rather than only against carryforwards that are created by unrecognized tax benefits. The provisions of this ASU are effective for interim and annual periods beginning on or after December 15, 2013. Teradyne does not expect this ASU to have a material impact on its financial position or results of operations.

D. Financial Instruments and Derivatives

Financial Instruments

Teradyne uses the market and income approach to value its financial instruments and there was no change in valuation techniques used by Teradyne during the three and six months ended June 30, 2013 and July 1, 2012. As defined in ASC 820-10, “Fair Value Measurements and Disclosures,” fair value is the price that would be received from the sale of an asset or paid to transfer a liability in an orderly transaction between market participants. ASC 820-10 requires that assets and liabilities are carried at fair value and are classified in one of the following three categories:

Level 1: Quoted prices in active markets for identical assets as of the reporting date.

Level 2: Inputs other than Level 1, that are observable either directly or indirectly as of the reporting date. For example, a common approach for valuing fixed income securities is the use of matrix pricing. Matrix pricing is a mathematical technique used to value securities by relying on the securities’ relationship to other benchmark quoted prices.

Level 3: Unobservable inputs that are not supported by market data. Unobservable inputs are developed based on the best information available, which might include Teradyne’s own data.

Most of Teradyne’s fixed income securities are classified as Level 2, with the exception of U.S. Treasury securities and investments in equity and debt mutual funds, which are classified as Level 1, and contingent consideration, which is classified as Level 3. The majority of Level 2 securities are priced by third party pricing vendors. These pricing vendors utilize the most recent observable market information in pricing these securities or, if specific prices are not available, use other observable inputs like market transactions involving identical or comparable securities.

There were no realized losses recorded in the three and six months ended June 30, 2013 and July 1, 2012. Realized gains recorded in the three and six months ended June 30, 2013 were $0.1 million and $0.3 million, respectively. Realized gains recorded in the three and six months ended July 1, 2012 were $0.3 million and $0.6 million, respectively. Realized gains are included in interest income.

During the six months ended June 30, 2013 and July 1, 2012, there were no transfers in or out of Level 1, Level 2 or Level 3 financial instruments.

Derivatives

Teradyne conducts business in a number of foreign countries, with certain transactions denominated in local currencies. The purpose of Teradyne’s foreign currency management is to minimize the effect of exchange rate fluctuations on certain foreign currency denominated net monetary assets. Teradyne does not use derivative financial instruments for trading or speculative purposes.

To minimize the effect of exchange rate fluctuations associated with the remeasurement of monetary assets and liabilities denominated in foreign currencies, Teradyne enters into foreign currency forward contracts. The change in fair value of these derivatives is recorded directly in earnings, and is used to offset the change in fair value of the monetary assets and liabilities denominated in foreign currencies.

The notional amount of foreign exchange contracts hedging monetary assets and liabilities denominated in foreign currencies was $54.0 million and $64.1 million at June 30, 2013 and December 31, 2012, respectively.

The following table summarizes the fair value of derivative instruments at June 30, 2013 and December 31, 2012.

E. Debt

Loan Agreement

On March 31, 2009, Teradyne K.K., Teradyne’s wholly-owned subsidiary in Japan, entered into a loan agreement with a local bank in Japan to borrow approximately $10.0 million (the loan is denominated in Japanese Yen). The loan has a term of 5 years and a fixed interest rate of 0.8%. Approximately $6.0 million of

##### Table of Contents

the loan is collateralized by a real estate mortgage on Teradyne K.K.’s building and land in Kumamoto, Japan and approximately $4.0 million is unsecured. Teradyne, Inc. has guaranteed payment of the loan obligation. The loan is amortized over the term of the loan with semiannual principal payments of approximately $1.0 million payable on September 30 and March 30 each year. At June 30, 2013, the outstanding loan principal of approximately $2.0 million is included in current debt.

Convertible Senior Notes

In April 2009, Teradyne issued 4.50% convertible senior notes (the “Notes”) at an aggregate principal amount of $190 million. The Notes will mature on March 15, 2014, unless earlier repurchased by Teradyne or converted. The Notes are senior unsecured obligations and rank equally with all of Teradyne’s existing and future senior debt and senior to any of Teradyne’s subordinated debt.

The Notes may be converted, at the option of the holder, under certain circumstances and during certain periods, at an initial conversion rate of approximately 182.65 shares of Teradyne’s common stock per $1,000 principal amount of Notes, which is equivalent to an initial conversion price of approximately $5.48, a 25% conversion premium based on the last reported sale price of $4.38 per share of Teradyne’s common stock on March 31, 2009. The conversion rate is subject to adjustment in certain circumstances including but not limited to Teradyne issuing a cash or stock dividend or effecting a stock split.

During the three months ended June 30, 2013, the following circumstance occurred that allows holders to convert their Notes at their option prior to December 15, 2013: the last reported sale price of Teradyne’s common stock for 20 or more trading days in a period of 30 consecutive trading days ending on the last trading day of the immediately preceding calendar quarter exceeded 130% of the conversion price in effect on the last trading day of the immediately preceding calendar quarter. As of August 9, 2013, one holder exercised the option to convert two thousand dollars worth of Notes which Teradyne settled in cash.

Concurrently with the offering of the Notes, Teradyne entered into a convertible note hedge transaction with a strike price equal to the initial conversion price of the Notes, or approximately $5.48. The convertible note hedge allows Teradyne to receive shares of its common stock and/or cash related to the excess conversion value that it would pay to the holders of the Notes upon conversion. The convertible note hedges will cover, subject to customary antidilution adjustments, approximately 34,703,196 shares of Teradyne’s common stock. Teradyne paid approximately $64.6 million for the convertible note hedges.

On March 31, 2009, Teradyne entered into a warrant transaction with a strike price of approximately $7.67 per share, which was 75% higher than the closing price of Teradyne’s common stock. Teradyne received approximately $43.0 million for the warrants.

The convertible note hedge and warrant transaction will generally have the effect of increasing the conversion price of the Notes to approximately $7.67 per share of Teradyne’s common stock, representing a 75% conversion premium based upon the closing price of Teradyne’s common stock on March 31, 2009.

The Notes are classified as current debt in the balance sheet at June 30, 2013. The tables below represent the components of Teradyne’s convertible senior notes:

|  | June 30, 2013 |  |  | December 31, 2012 |

H. Stock-Based Compensation

Restricted stock unit awards granted to employees vest in equal installments over four years. A portion of restricted stock unit awards granted to executive officers is subject to time-based vesting and a portion is subject to performance-based vesting. The percentage level of performance satisfied for performance-based grants is assessed on or near the anniversary of the grant date and, in turn, that percentage level determines the number of performance-based restricted stock units available for vesting over the vesting period; portions of the performance-based grants not available for vesting will be forfeited. Stock options vest in equal installments over four years, and have a term of seven years from the date of grant.

During the six months ended June 30, 2013, Teradyne granted 1.9 million of restricted stock unit awards to employees at a weighted average grant date fair value of $16.60 and 0.2 million of service-based stock options to executive officers at a weighted average grant date fair value of $6.09.

During the six months ended July 1, 2012, Teradyne granted 1.6 million of restricted stock unit awards to employees at a weighted average grant date fair value of $16.83 and 0.2 million of service-based stock options to executive officers at a weighted average grant date fair value of $6.85.

The fair value of stock options was estimated using the Black-Scholes option-pricing model with the following assumptions:

|  | For the Six Months Ended |
|  | June 30, 2013 |  |  | July 1, 2012 |
Expected life (years) |  |  | 4.0 |  |  |  | 3.5 |
Interest rate |  |  | 0.6 | % |  |  | 0.4 | %
Volatility-historical |  |  | 46.8 | % |  |  | 56.0 | %
Dividend yield |  |  | 0.0 | % |  |  | 0.0 | %

Teradyne determined the stock options’ expected life based upon historical exercise data for executive officers, the age of the executive officers and the terms of the stock option grant. Volatility was determined using historical volatility for a period equal to the expected life. The risk-free rate was determined using the U.S. Treasury yield curve in effect at the time of grant.

Effective January 1, 2013, the price paid by employees for Teradyne’s common stock purchased through the employee stock purchase plan is equal to 85% of the stock price on the last business day of the purchase period.

##### Table of Contents

During 2012, the price paid by employees for Teradyne’s common stock purchased through the employee stock purchase plan was equal to 85% of the lower of the stock price on the first or last business day of the purchase period.

The weighted-average fair value of employee stock purchase rights granted in the six months ended July 1, 2012 was $4.09. The fair value of the employees’ purchase rights granted in the six months ended July 1, 2012 was estimated using the Black-Scholes option-pricing model with the following assumptions:

|  | For the Six Months Ended July 1, 2012 |
Expected life (years) |  |  | 0.5 |
Interest rate |  |  | 0.06 | %

(1) | Incremental shares from assumed conversion of the convertible notes for the three and six months ended June 30, 2013 and July 1, 2012 are calculated using the difference between the average Teradyne stock price for the period and the conversion price of $5.48, multiplied by the 34.7 million shares that would be issued upon conversion. The result of this calculation, representing the total intrinsic value of the convertible debt, is divided by the average Teradyne stock price for the period.

(2) | Convertible note hedge warrant shares for the three and six months ended June 30, 2013 and July 1, 2012 are calculated using the difference between the average Teradyne stock price for the period and the warrant price of $7.67, multiplied by the 34.7 million shares that would be issued upon conversion. The result of this calculation, representing the total intrinsic value of the warrant, is divided by the average Teradyne stock price for the period.

The computation of diluted net income per common share for the three and six months ended June 30, 2013 excludes the effect of the potential exercise of stock options to purchase approximately 0.5 million shares because the effect would have been anti-dilutive.

The computation of diluted net income per common share for the three and six months ended July 1, 2012 excludes the effect of the potential exercise of stock options to purchase approximately 0.3 million shares and restricted stock units of 0.1 million because the effect would have been anti-dilutive.

With respect to Teradyne’s convertible debt, Teradyne intends to settle its conversion spread (i.e., the intrinsic value of the embedded option feature contained in the convertible debt) in shares. Teradyne accounts for its conversion spread using the treasury stock method.

L. Restructuring and Other

Other

During the three and six months ended July 1, 2012, due to a decrease in specified new product revenue through the December 31, 2012 earn-out period end date, Teradyne recorded a $6.5 million and $8.4 million, respectively, fair value adjustment to decrease the LitePoint acquisition contingent consideration.

Restructuring

In response to a downturn in the industry in 2008 and 2009, Teradyne initiated restructuring activities across its Semiconductor Test and Systems Test segments to reduce costs, principally through headcount reductions and facility consolidations. The remaining accrual for facility consolidations of $0.6 million is reflected in the other accrued liabilities on the balance sheet and is expected to be paid by October 2013.

M. Retirement Plans

Defined Benefit Pension Plans

Teradyne has defined benefit pension plans covering a portion of domestic employees and employees of certain non-U.S. subsidiaries. Benefits under these plans are based on employees’ years of service and compensation. Teradyne’s funding policy is to make contributions to these plans in accordance with local laws and to the extent that such contributions are tax deductible. The assets of these plans consist primarily of fixed income and equity securities. In addition, Teradyne has an unfunded supplemental executive defined benefit plan in the United States to provide retirement benefits in excess of levels allowed by the Employment Retirement Income Security Act (“ERISA”) and the Internal Revenue Code (“IRC”), as well as unfunded foreign plans.

Net periodic pension (benefit) cost was comprised of the following:

|  | For the Three Months Ended |  |  | For the Six Months Ended |
|  | June 30, 2013 |  |  | July 1, 2012 |  |  | June 30, 2013 |  |  | July 1, 2012 |

##### Table of Contents

In the six months ended June 30, 2013, Teradyne contributed $0.9 million to the U.S. supplemental executive defined benefit pension plan and $1.0 million to certain qualified plans for non-U.S. subsidiaries.

Postretirement Benefit Plan

In addition to receiving pension benefits, U.S. Teradyne employees who meet early retirement eligibility requirements as of their termination dates may participate in Teradyne’s Welfare Plan, which includes death, and medical and dental benefits up to age 65. Death benefits provide a fixed sum to retirees’ survivors and are available to all retirees. Substantially all of Teradyne’s current U.S. employees could become eligible for these benefits, and the existing benefit obligation relates primarily to those employees.

Teradyne’s net periodic postretirement benefit was comprised of the following:

|  | For the Three Months Ended |  |  | For the Six Months Ended |
|  | June 30, 2013 |  |  | July 1, 2012 |  |  | June 30, 2013 |  |  | July 1, 2012 |

N. Commitments and Contingencies

Purchase Commitments

As of June 30, 2013, Teradyne had entered into purchase commitments for certain components and materials. The purchase commitments aggregate to approximately $265.0 million, of which $261.7 million is for less than one year.

Legal Claims

Teradyne is subject to various legal proceedings and claims which have arisen in the ordinary course of business. In the opinion of management, other than set forth herein, the ultimate disposition of these matters will not have a material adverse effect on Teradyne’s results of operations, financial condition or cash flows.

On May 17, 2013, Boston Semi Equipment (“BSE”) filed a complaint against Teradyne for antitrust violations and unfair business practices alleging that Teradyne is excluding BSE from competing in the market for the sale of reconfigured Teradyne equipment and the market for the repair of Teradyne equipment. BSE seeks unspecified damages and an injunction. Teradyne has filed a motion to dismiss the complaint. Teradyne believes it has meritorious defenses against this claim and intends to vigorously defend against it. While it is not possible to predict or determine the outcomes of the unsettled claims or to provide possible ranges of losses that may arise, Teradyne believes the potential losses associated with this action are unlikely to have a material adverse effect on its consolidated financial position, but could possibly be material to its consolidated results of operations and of cash flows of any one period.

O. Income Taxes

The effective tax rate for the three months ended June 30, 2013 and July 1, 2012 was 17% and 27%, respectively. The decrease in Teradyne’s tax rate for the three months ended June 30, 2013 compared to the three

19

##### Table of Contents

months ended July 1, 2012, was primarily the result of the 2013 U.S. federal research and development tax credit and utilization of foreign tax credits.

The effective tax rate for the six months ended June 30, 2013 and July 1, 2012 was 7% and 25%, retrospectively. The decrease in Teradyne’s tax rate for the six months ended June 30, 2013 compared to the six months ended July 1, 2012, was primarily the result of recognizing the tax benefit attributable to the 2012 U.S. federal research and development tax credit retrospectively reinstated under the American Taxpayer Relief Act of 2012, 2013 U.S. federal research and development tax credit and utilization of foreign tax credits.

The effective tax rate for the three months and six months ended June 30, 2013 is lower than the 35% U.S. statutory federal tax rate primarily due to the research and development credit and the effect of foreign income taxed at a rate lower than the U.S. statutory rate

P. Segment Information

Teradyne has three operating segments (Semiconductor Test, Wireless Test and Systems Test), which are its reportable segments. The Semiconductor Test segment includes operations related to the design, manufacturing and marketing of semiconductor test products and services. The Wireless Test segment includes operations related to design, manufacturing and marketing of wireless test products and services. The Systems Test segment includes operations related to design, manufacturing and marketing of products and services for military/aerospace instrumentation test, storage test and circuit-board test. Each operating segment has a segment manager who is directly accountable to and maintains regular contact with Teradyne’s chief operating decision maker (Teradyne’s chief executive officer) to discuss operating activities, financial results, forecasts, and plans for the segment.

Teradyne evaluates performance based on several factors, of which the primary financial measure is business segment income before income taxes. The accounting policies of the business segments are the same as those described in Note B “Accounting Policies” in Teradyne’s Annual Report on Form 10-K for the year ended December 31, 2012.

Overview

We are a leading global supplier of automatic test equipment. We design, develop, manufacture and sell automatic test systems and solutions used to test semiconductors, wireless products, hard disk drives and circuit boards in the consumer electronics, wireless, automotive, industrial, computing, communications and aerospace and defense industries. Our automatic test equipment products and services include:

| • |  | semiconductor test (“Semiconductor Test”) systems;

| • |  | wireless test (“Wireless Test”) systems; and

| • |  | military/aerospace (“Mil/Aero”) test instrumentation and systems, storage test (“Storage Test”) systems, and circuit-board test and inspection (“Commercial Board Test”) systems, collectively these products represent “Systems Test”.

We have a broad customer base which includes integrated device manufacturers (“IDMs”), outsourced semiconductor assembly and test providers (“OSATs”), wafer foundries, fabless companies that design, but contract with others for the manufacture of integrated circuits (“ICs”), developers of wireless devices and consumer electronics, manufacturers of circuit boards, automotive suppliers, wireless product manufacturers, storage device manufacturers, aerospace and military contractors.

In 2011, we acquired LitePoint Corporation (“LitePoint”) to expand our product portfolio of test equipment in the wireless test sector. LitePoint designs, develops, and supports advanced wireless test solutions for the development and manufacturing of wireless devices, including smart phones, tablets, notebooks/laptops, personal computer peripherals, and other Wi-Fi and cellular enabled devices. LitePoint is our Wireless Test segment.

The sales of our products and services are dependent, to a large degree, on customers who are subject to cyclical trends in the demand for their products. These cyclical periods have had, and will continue to have, a significant effect on our business since our customers often delay or accelerate purchases in reaction to changes in their businesses and to demand fluctuations in the semiconductor industry. Historically, these demand fluctuations have resulted in significant variations in our results of operations.

We believe our acquisitions of LitePoint, Eagle Test and Nextest, and our entry into the high speed memory and storage test markets have enhanced our opportunities for growth. We will continue to invest in our business to expand further our addressable markets while tightly managing our costs.

Critical Accounting Policies and Estimates

We have identified the policies which are critical to understanding our business and our results of operations. There have been no significant changes during the six months ended June 30, 2013 to the items disclosed as our critical accounting policies and estimates in Management’s Discussion and Analysis of Financial Condition and Results of Operations in our Annual Report on Form 10-K for the fiscal year ended December 31, 2012.

Revenues

Net revenues by reportable segment were as follows:

|  | For the Three Months Ended |  |  | Dollar Change |
|  | June 30, 2013 |  |  | July 1, 2012 |  |
|  | (in millions) |
Semiconductor Test |  | $ | 292.4 |  |  | $ | 365.1 |  |  | $ | (72.7 | )
Wireless Test |  |  | 99.4 |  |  |  | 111.9 |  |  |  | (12.5 | )

|  | $ | 428.9 |  |  | $ | 548.3 |  |  | $ | (119.4 | )

The decrease in Semiconductor Test revenues of $72.7 million or 20% from the three months ended July 1, 2012 to the three months ended June 30, 2013, was primarily due to a decrease in system-on-a-chip (“SOC”) test product sales. The decrease in Systems Test revenue of $34.2 million or 48% was primarily due to a decrease in sales due to lower product volume in Storage Test systems. The decrease in Storage Test systems sales was due to lower hard disk drive demand primarily from lower shipments of personal computers, a trend which is expected to continue. The decrease in Wireless Test revenue of $12.5 million or 11% was primarily due to lower volume.

Our revenues by region as a percentage of total net revenue were as follows:

##### Table of Contents

lower sales volume, a decrease of 1.5 points related to product mix primarily from lower Wireless Test systems sales, partially offset by lower excess and obsolete inventory provisions.

We assess the carrying value of our inventory on a quarterly basis by estimating future demand and comparing that demand against on-hand and on-order inventory positions. Forecasted revenue information is obtained from the sales and marketing groups and incorporates factors such as backlog and future revenue demand. This quarterly process identifies obsolete and excess inventory. Obsolete inventory, which represents items for which there is no demand, is fully reserved. Excess inventory, which represents inventory items that are not expected to be consumed during the next twelve quarters, is written-down to estimated net realizable value.

During the three months ended June 30, 2013, we recorded an inventory provision of $2.0 million included in cost of revenues, due to downward revisions to previously forecasted demand levels. Of the $2.0 million of total excess and obsolete provisions, $1.4 million was related to Wireless Test, $0.3 million was related to Systems Test, and $0.3 million was related to Semiconductor Test.

During the three months ended July 1, 2012, we recorded an inventory provision of $9.4 million included in cost of revenues, due to the following factors:

| • |  | A decline in demand versus previously forecasted demand levels for a prior generation Nextest Magnum resulted in an inventory provision of $3.2 million.

| • |  | A $2.6 million inventory write-down as a result of product transition related to the Flex Test Platform in Semiconductor Test.

| • |  | The remainder of the charge of $3.6 million primarily reflects downward revisions to previously forecasted demand levels, of which $1.8 million was related to Systems Test, $1.6 million was related to Wireless Test and $0.2 million was related to Semiconductor Test.

During the three months ended June 30, 2013 and July 1, 2012, we scrapped $2.3 million and $2.8 million of inventory, respectively. During the three months ended June 30, 2013, we sold $3.1 million of previously written-down or written-off inventory. As of June 30, 2013, we had inventory related reserves for inventory which had been written-down or written-off totaling $140.0 million. We have no pre-determined timeline to scrap the remaining inventory.

Engineering and Development

Engineering and development expenses were as follows:

Percent of Total Revenue |  |  | 15.8 | % |  |  | 12.4 | % |  |  |  |

Engineering and development expenses remained flat as higher spending in Semiconductor Test was offset by lower variable compensation.

Selling and Administrative

Selling and administrative expenses were as follows:

|  | For the Three Months Ended |  |  | Dollar Change |
|  | June 30, 2013 |  |  | July 1, 2012 |  |
|  | (in millions) |
Selling and Administrative |  | $ | 69.2 |  |  | $ | 72.1 |  |  | $ | (2.9 | )
Percent of Total Revenue |  |  | 16.1 | % |  |  | 13.1 | % |  |  |  |

The decrease of $2.9 million in selling and administrative expenses from the three months ended July 1, 2012 to the three months ended June 30, 2013, was due primarily to lower variable compensation, partially offset by increased sales and marketing spending in Semiconductor Test and Wireless Test.

Restructuring and Other

During the three months ended July 1, 2012, due to a decrease in specified new product revenue through the December 31, 2012 earn-out period end date, we recorded a $6.5 million fair value adjustment to decrease the LitePoint acquisition contingent consideration.

Interest and Other

Interest expense and other increased by $0.1 million from the three months ended July 1, 2012 to the three months ended June 30, 2013, due primarily to higher interest expense from increased convertible debt discount amortization.

Income Taxes

The effective tax rate for the three months ended June 30, 2013 and July 1, 2012 was 17% and 27%, respectively. The decrease in our tax rate for the three months ended June 30, 2013 compared to the three months ended July 1, 2012, was primarily the result of the 2013 U.S. federal research and development tax credit and utilization of foreign tax credits.

The effective tax rate for the three months ended June 30, 2013 is lower than the 35% U.S. statutory federal tax rate primarily due to the research and development credit and the effect of foreign income taxed at a rate lower than the U.S. statutory rate.

On a quarterly basis, we evaluate the realizability of our deferred tax assets by jurisdiction and assess the need for a valuation allowance. At June 30, 2013, we believe that we will ultimately realize the deferred tax assets recorded on our condensed consolidated balance sheet. However, should we believe that it is more likely than not that our deferred tax assets would not be realized, our tax provision would increase in the period in which we determined that the realizability was not likely. We consider the probability of future taxable income and our historical profitability, among other factors, in assessing the realizability of our deferred tax assets.

Six Months of 2013 Compared to Six Months of 2012

Revenues

Net revenues by reportable segment were as follows:

|  | For the Six Months Ended |  |  | Dollar Change |
|  | June 30, 2013 |  |  | July 1, 2012 |  |
|  | (in millions) |
Semiconductor Test |  | $ | 504.0 |  |  | $ | 632.6 |  |  | $ | (128.6 | )

|  | $ | 709.3 |  |  | $ | 945.0 |  |  | $ | (235.7 | )

The decrease of $128.6 million or 20% in Semiconductor Test revenues from the six months ended July 1, 2012 to the six months ended June 30, 2013, was primarily due to a decrease in system-on-a-chip (“SOC”) test product sales. The decrease in Systems Test revenue of $96.8 million or 57% was primarily due to a decrease in sales due to lower product volume in Storage Test systems. The decrease in Storage Test systems sales was due to lower hard disk drive demand primarily from lower shipments of personal computers, a trend which is expected to continue. The decrease in Wireless Test revenue of $10.3 million or 7% was primarily due to lower volume.

Our revenues by region as a percentage of total net revenues were as follows:

##### Table of Contents

Gross profit as a percent of revenue increased by 2.6 percentage points from the six months ended July 1, 2012 to the six months ended June 30, 2013, primarily due to a favorable product mix in SOC Semiconductor Test and lower Storage Test systems sales.

We assess the carrying value of our inventory on a quarterly basis by estimating future demand and comparing that demand against on-hand and on-order inventory positions. Forecasted revenue information is obtained from the sales and marketing groups and incorporates factors such as backlog and future revenue demand. This quarterly process identifies obsolete and excess inventory. Obsolete inventory, which represents items for which there is no demand, is fully reserved. Excess inventory, which represents inventory items that are not expected to be consumed during the next twelve quarters, is written-down to estimated net realizable value.

During the six months ended June 30, 2013, we recorded an inventory provision of $5.8 million included in cost of revenues, due to the downward revisions to previously forecasted demand levels. Of the $5.8 million of total excess and obsolete provisions, $4.1 million was related to Wireless Test, $1.2 million was related to Systems Test, and $0.5 million was related to Semiconductor Test.

During the six months ended July 1, 2012, we recorded an inventory provision of $10.9 million included in cost of revenues, due to the following factors:

| • |  | A decline in demand versus previously forecasted demand levels for a prior generation Nextest Magnum resulted in an inventory provision of $3.2 million.

| • |  | A $2.6 million inventory write-down as a result of product transition related to the Flex Test Platform in Semiconductor Test.

| • |  | The remainder of the charge of $5.1 million primarily reflects downward revisions to previously forecasted demand levels, of which $2.6 million was related to Systems Test, $2.1 million was related to Wireless Test and $0.4 million was related to Semiconductor Test.

During the six months ended June 30, 2013 and July 1, 2012, we scrapped $2.9 million and $6.9 million of inventory, respectively. During the six months ended June 30, 2013 and July 1, 2012, we sold $4.8 million and $1.3 million, respectively, of previously written-down or written-off inventory. As of June 30, 2013, we had inventory related reserves for inventory which had been written-down or written-off totaling $140.0 million. We have no pre-determined timeline to scrap the remaining inventory.

Engineering and Development

Engineering and development expenses were as follows:

|  | For the Six Months Ended |  |  | Dollar Change |

Percent of Total Revenue |  |  | 19.3 | % |  |  | 14.7 | % |  |  |  |

The decrease of $1.6 million in selling and administrative expenses from the six months ended July 1, 2012 to the six months ended June 30, 2013, was due primarily to lower variable compensation, partially offset by increased sales and marketing spending in Semiconductor Test and Wireless Test.

Restructuring and Other

During the six months ended July 1, 2012, due to a decrease in specified new product revenue through the December 31, 2012 earn-out period end date, we recorded an $8.4 million fair value adjustment to decrease the LitePoint acquisition contingent consideration.

Interest and Other

Interest income increased by $0.2 million from the six months ended July 1, 2012 to the six months ended June 30, 2013, due primarily to higher cash and marketable securities balances in the first six months of 2013. Interest expense and other increased by $1.0 million from the six months ended July 1, 2012 to the six months ended June 30, 2013, due primarily to higher interest expense from increased convertible debt discount amortization.

Income Taxes

The effective tax rate for the six months ended June 30, 2013 and July 1, 2012 was 7% and 25%, retrospectively. The decrease in our tax rate for the six months ended June 30, 2013 compared to the six months ended July 1, 2012, was primarily the result of recognizing the tax benefit attributable to the 2012 U.S. federal research and development tax credit retrospectively reinstated under the American Taxpayer Relief Act of 2012, 2013 U.S. federal research and development tax credit and utilization of foreign tax credits.

The effective tax rate for the six months ended June 30, 2013 is lower than the 35% U.S. statutory federal tax rate primarily due to the research and development credit and the effect of foreign income taxed at a rate lower than the U.S. statutory rate.

On a quarterly basis, we evaluate the realizability of our deferred tax assets by jurisdiction and assess the need for a valuation allowance. At June 30, 2013, we believe that we will ultimately realize the deferred tax assets recorded on our condensed consolidated balance sheet.

(1) | Included in Other Long-Term Liabilities are liabilities for customer advances, extended warranty, uncertain tax positions and other obligations.

Liquidity and Capital Resources

Our cash, cash equivalents and marketable securities balances increased by $25.3 million in the six months ended June 30, 2013, to $1,032 million. Cash activity for the six months ended June 30, 2013 and July 1, 2012 was as follows:

|  | For the Six Months Ended |
|  | June 30, 2013 |  |  | July 1, 2012 |
|  | (in millions) |
Cash provided by operating activities: |  |  |  |  |  |  |  |
Net income, adjusted for non-cash items |  | $ | 152.5 |  |  | $ | 255.2 |
Change in operating assets and liabilities |  |  | (83.5 | ) |  |  | (141.9 | )
Total cash provided by operating activities |  |  | 69.0 |  |  |  | 113.3 |
Total cash used for investing activities |  |  | (190.1 | ) |  |  | (115.5 | )
Total cash provided by financing activities |  |  | 9.8 |  |  |  | 17.5 |
(Decrease) increase in cash and cash equivalents |  | $ | (111.3 | ) |  | $ | 15.3 |

In the six months ended June 30, 2013, changes in operating assets and liabilities used cash of $83.5 million. This was due to a $65.7 million increase in operating assets and an $17.8 million decrease in operating liabilities.

The increase in operating assets was due to a $74.8 million increase in accounts receivable due to higher sales volume, a $17.3 million increase in other assets primarily due to an increase in prepayments, partially offset by a $26.4 million decrease in inventories. The decrease in operating liabilities was due to a $24.0 million decrease in accrued employee compensation due primarily to variable compensation and employee stock awards payroll taxes payments, a $3.1 million decrease in customer advance payments and deferred revenue, and $2.5 million of retirement plan contributions, partially offset by a $8.8 million increase in accounts payable due to increased sales volume and a $3.0 million increase in accrued income taxes.

Investing activities during the six months ended June 30, 2013 used cash of $190.1 million, due to $458.1 million used for purchases of marketable securities and $50.8 million used for purchases of property, plant and equipment, partially offset by proceeds from maturities and sales of marketable securities that provided cash of $268.5 million and $50.3 million, respectively.

Financing activities during the six months ended June 30, 2013 provided cash of $9.8 million, $9.6 million was from the issuance of common stock under stock option and stock purchase plans and $1.6 million from the tax benefit related to stock options and restricted stock units, partially offset by $0.4 million of cash used for payments related to LitePoint acquisition contingent consideration and $1.1 million of cash used for payments on long-term debt related to the Japan loan.

In the six months ended July 1, 2012, changes in operating assets and liabilities used cash of $141.9 million. This was due to a $190.3 million increase in operating assets, partially offset by a $48.4 million increase in operating liabilities.

The increase in operating assets was due to a $216.8 million increase in accounts receivable resulting from higher sales volume, partially offset by a $21.4 million decrease in inventories and a $5.0 million decrease in other assets primarily due to a decrease in prepayments. The increase in operating liabilities was due to a $47.5 million increase in accounts payable due to increased sales volume, a $30.0 million increase in accrues income taxes, and a $1.1 million increase in other accrued liabilities, partially offset by a $21.4 million decrease in accrued employee compensation due primarily to variable compensation and employee stock awards payroll taxes payments, a $6.2 million decrease in customer advance payments and deferred revenue and $2.6 million of retirement plan contributions.

Investing activities during the six months ended July 1, 2012 used cash of $115.5 million, due to $153.9 million used for purchases of marketable securities and $57.8 million used for purchases of property, plant and equipment, partially offset by proceeds from maturities and sales of marketable securities that provided cash of $86.2 million and $10.0 million, respectively.

Financing activities during the six months ended July 1, 2012 provided cash of $17.5 million, $17.0 million was from the issuance of common stock under stock option and stock purchase plans, and $7.6 million from the tax benefit related to stock options and restricted stock units, partially offset by $5.8 million of cash used for payments related to LitePoint acquisition contingent consideration and $1.2 million of cash used for payments on long-term debt related to the Japan loan.

We believe our cash, cash equivalents and marketable securities balance will be sufficient to meet working capital and expenditure needs for at least the next twelve months. The amount of cash, cash equivalents and marketable securities in the U.S. and our operations in the U.S. provide sufficient liquidity to fund our business activities in the U.S. We have approximately $330 million of cash outside the U.S. that if repatriated would incur additional taxes. Inflation has not had a significant long-term impact on earnings.

Equity Compensation Plans

As discussed in Note P “Stock Based Compensation” in our 2012 Form 10-K, we have a 1996 Employee Stock Purchase Plan and a 2006 Equity and Cash Compensation Incentive Plan (the “2006 Equity Plan”).

The purpose of the 1996 Employee Stock Purchase Plan is to encourage stock ownership by all eligible employees of Teradyne. The purpose of the 2006 Equity Plan is to provide equity ownership and compensation opportunities in Teradyne to our employees, officers, directors, consultants and/or advisors. Both plans were approved by our shareholders.

Recently Issued Accounting Pronouncements

In December 2011, the FASB issued ASU No. 2011-11, “Disclosures about Offsetting Assets and Liabilities.” This ASU is intended to enhance the understanding of the effects of netting arrangements on an entity’s financial statements, including financial instruments and derivative instruments that are either offset or subject to a master netting arrangement. The scope of this ASU includes derivatives, sale and repurchase agreements, reverse sale and repurchase agreements, and securities borrowing and lending arrangements. The provisions of this ASU are effective for interim and annual periods beginning on or after January 1, 2013. We adopted this ASU effective January 1, 2013. See Note D “Financial Instruments and Derivatives.”

In February 2013, the Financial Accounting Standards Board (FASB) issued ASU 2013-02, “Comprehensive Income (Topic 220): Reporting of Amounts Reclassified out of Accumulated Other Comprehensive Income” amending the disclosure requirements regarding the reporting of amounts reclassified out of accumulated other comprehensive income. The amendment does not change the current requirement for reporting net income or other comprehensive income, but requires additional disclosures about significant amounts reclassified out of accumulated other comprehensive income including the effect of the reclassification on the related statement of operations line items. The provisions of this ASU are effective for interim and annual periods beginning on or after January 1, 2013. We adopted this amendment effective January 1, 2013. See Note I “Accumulated Other Comprehensive Income.”

On July 18, 2013, the FASB issued ASU 2013-11, “Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists.” This ASU, unrecognized tax benefits will be netted against all available same-jurisdiction loss or other tax carryforwards that would be utilized, rather than only against carryforwards that are created by unrecognized tax benefits. The provisions of this ASU are effective for interim and annual periods beginning on or after December 15, 2013. We do not expect this ASU to have a material impact on our financial position or results of operations.

Item 3: | Quantitative and Qualitative Disclosures about Market Risk

For “Quantitative and Qualitative Disclosures about Market Risk” affecting Teradyne, see Item 7a, “Quantitative and Qualitative Disclosures about Market Risks,” in our Annual Report on Form 10-K filed with the SEC on March 1, 2013. There were no material changes in our exposure to market risk from those set forth in our Annual Report for the fiscal year ended December 31, 2012.

Item 4: | Controls and Procedures

As of the end of the period covered by this report, our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures pursuant to Rule 13a-15(b) promulgated under the Exchange Act. Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that, as of the end of the period covered by this report, our disclosure controls and procedures were effective in ensuring that material information required to be disclosed in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, including ensuring that such material information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

During the period covered by this report, there have been no changes in our internal control over financial reporting that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met.

PART II. OTHER INFORMATION

Item 1: | Legal Proceedings

We are subject to various legal proceedings and claims which have arisen in the ordinary course of business. In the opinion of management, other than as set forth herein, the ultimate disposition of these matters will not have a material adverse effect on our results of operations, financial condition or cash flows.

On May 17, 2013, Boston Semi Equipment (“BSE”) filed a complaint against us for antitrust violations and unfair business practices alleging that we are excluding BSE from competing in the market for the sale of reconfigured Teradyne equipment and the market for the repair of Teradyne equipment. BSE seeks unspecified damages and an injunction. We filed a motion to dismiss the complaint. We believe we have meritorious defenses against this claim and intend to vigorously defend against it. While it is not possible to predict or determine the outcomes of the unsettled claims or to provide possible ranges of losses that may arise, we believe the potential losses associated with this action is unlikely to have a material adverse effect on our consolidated financial position, but could possibly be material to our consolidated results of operations and of cash flows of any one period.

Item 1A: | Risk Factors

In addition to the other information set forth in this Form 10-Q, you should carefully consider the factors discussed in Part I, “Item 1A: Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2012, which could materially affect our business, financial condition or future results. The risk factors described in our Annual Report on Form 10-K remain applicable to our business.

The risks described in our Annual Report on Form 10-K are not the only risks that we face. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial condition and/or operating results.

A breach of our operational or security systems could negatively affect our business and results of operations.

A failure in or a breach of our operational or security systems or infrastructure, or those of our suppliers and other service providers, including as a result of cyber attacks, could disrupt our business, result in the disclosure or misuse of proprietary or confidential information, damage our reputation, cause losses and increase our costs.

Item 2: | Unregistered Sales of Equity Securities and Use of Proceeds

In November 2010, Teradyne’s board of directors authorized a stock repurchase program for up to $200 million. Cumulatively, as of June 30, 2013, we have repurchased 2.6 million shares of common stock for $31.2 million at an average price of $11.84.
