TERADYNE, INC.

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 (“Production Board Test”) systems (collectively these products represent “System Test”).

B. Accounting Policies

Basis of Presentation

The 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, 2013 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. Securities and Exchange Commission (“SEC”) on February 28, 2014, for the year ended December 31, 2013.

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

On July 18, 2013, Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) No. 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’s implementation of this ASU did not have a material impact on Teradyne’s financial position and results of operations.

In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers (Topic 606)” which will replace numerous requirements in U.S. GAAP, including industry-specific requirements, and provide companies with a single revenue recognition model for recognizing revenue from contracts with customers. The

5

##### Table of Contents

core principle of the new standard is that a company should recognize revenue to show the transfer of promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. The new standard will be effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. For Teradyne, the standard will be effective in the first quarter of 2017. The two permitted transition methods under the new standard are the full retrospective method, in which case the standard would be applied to each prior reporting period presented, or the modified retrospective method, in which case the cumulative effect of applying the standard would be recognized at the date of initial application. Teradyne has not yet selected a transition method. Teradyne is currently evaluating the impact of this ASU on its financial position and results of operations.

D. Financial Instruments and Derivatives

Cash Equivalents

Teradyne considers all highly liquid investments with maturities of three months or less at the date of acquisition to be cash equivalents.

Financial Instruments

Teradyne accounts for its investments in debt and equity securities in accordance with the provisions of ASC 320-10, “Investments—Debt and Equity Securities.” ASC 320-10 requires that certain debt and equity securities be classified into one of three categories; trading, available-for-sale or held-to-maturity securities. As of September 28, 2014, Teradyne’s investments in debt and equity securities were classified as available-for-sale and recorded at their fair market value.

On a quarterly basis, Teradyne reviews its investments to identify and evaluate those that have an indication of a potential other-than-temporary impairment. Factors considered in determining whether a loss is other-than-temporary include:

| • |  | The length of time and the extent to which the market value has been less than cost;

| • |  | The financial condition and near-term prospects of the issuer; and

| • |  | The intent and ability to retain the investment in the issuer for a period of time sufficient to allow for any anticipated recovery in market value.

Teradyne uses the market and income approach techniques to value its financial instruments and there were no changes in valuation techniques during the three and nine months ended September 28, 2014 and September 29, 2013. 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 carried at fair value be classified and disclosed 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, a technique used to value securities by relying on the securities’ relationship to other benchmark quoted prices, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

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.

Substantially all of Teradyne’s fixed income securities are classified as Level 2, with the exception of 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 Teradyne’s Level 2 securities are priced by 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.

During the nine months ended September 28, 2014 and September 29, 2013, there were no transfers in or out of Level 1, Level 2 or Level 3 financial instruments.

Contingent consideration relates to Teradyne’s acquisition of ZTEC Instruments, Inc. (“ZTEC”) on October 25, 2013. The total purchase price included $2.2 million in fair value of contingent consideration payable upon achievement of certain customer order and revenue targets through 2015. The maximum amount of contingent consideration that could be paid is $5.0 million. Based on the projected results for the acquisition, no value was assigned to the revenue component of the contingent consideration.

The acquisition date valuation of the customer order component of the contingent consideration utilized the following assumptions: (1) probability of meeting each benchmark; (2) expected timing of meeting each benchmark; and (3) discount rate reflecting the risk associated with the expected payments. The probabilities and timing for each benchmark were estimated based on a review of the historical and projected results. A discount rate of 5.2 percent was selected based on the cost of debt for the business, as a significant portion of the risk in achieving the customer order contingent consideration was captured in the probabilities assigned to meeting each benchmark. Teradyne assesses these assumptions and estimates on a quarterly basis as additional data impacting the assumptions is obtained. During the three and nine months ended September 28, 2014, the fair value of the customer order component of the contingent consideration was reduced by $0.6 million based on updated assumptions and estimates. The fair value reduction was recorded as a gain in restructuring and other in the statement of operations.

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 monetary assets and liabilities. 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 value of the monetary assets and liabilities denominated in foreign currencies.

The notional amount of foreign currency forward contracts was $67.9 million and $74.8 million at September 28, 2014 and December 31, 2013, respectively.

The fair value of the outstanding contracts was a loss of $0.6 million and a gain of $0.2 million at September 28, 2014 and December 31, 2013, respectively. The following table summarizes the fair value of derivative instruments at September 28, 2014 and December 31, 2013:

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 was denominated in Japanese Yen). The loan had a term of 5 years and a fixed interest rate of 0.8%. Approximately $6.0 million of the loan was collateralized by a real estate mortgage on Teradyne K.K.’s building and land in Kumamoto, Japan and approximately $4.0 million was unsecured. Teradyne, Inc. guaranteed payment of the loan obligation. The loan was amortized over the term of the loan with semiannual principal payments of approximately $1.0 million on September 30 and March 30 each year. The final principal and interest payments were made in March 2014.

Convertible Senior Notes

In April 2009, Teradyne issued 4.50% convertible senior notes (the “Notes”) at an aggregate principal amount of $190 million and a conversion price of $5.4750 or 182.65 shares of Teradyne’s common stock per $1,000 principal amount of Notes. The Notes had a maturity date of March 15, 2014. Substantially all of the Notes were converted prior to March 15, 2014 and were “net share settled,” meaning that the holders received, for each $1,000 in principal amount of Notes, $1,000 in cash and approximately 131.95 shares of Teradyne common stock (calculated by taking 182.65 shares less 50.7 shares). The 50.7 shares were determined by dividing the $1,000 principal amount by the $19.74 average trading price of Teradyne’s common stock over the 25 day trading period from February 5, 2014 to March 12, 2014.

Teradyne satisfied the Notes “net share settlement” by paying the aggregate principal amount of $190 million in cash and issuing 25.1 million shares of common stock. On March 13, 2014, Teradyne exercised its call option agreement entered into with Goldman, Sachs & Co. (the “hedge counterparty”) at the time of issuance of the Notes and received 25.1 million shares of Teradyne’s common stock, which were retired.

From June 17, 2014 to September 17, 2014, the hedge counterparty exercised its warrant agreement entered into with Teradyne at the time of issuance of the Notes. The warrants were net share settled. In the three and nine months ended September 28, 2014, Teradyne issued 19.3 million and 21.2 million shares of its common stock, respectively, for warrants exercised at a weighted average strike price of $7.6348 and $7.6351, respectively.

I. Stock-Based Compensation

In January 2014, Teradyne granted 0.1 million of performance-based restricted stock units (“PRSUs”) to its executive officers with a performance metric based on relative total shareholder return (“TSR”). Teradyne’s three-year TSR performance will be measured against the Philadelphia Semiconductor Index, which consists of thirty companies in the semiconductor device and capital equipment industries. The final number of TSR PRSUs that vest will vary based upon the level of performance achieved from 200% of the target shares to 0% of the target shares. All TSR PRSUs will vest upon the three-year anniversary of the January 24, 2014 grant date. No TSR PRSUs will vest if the executive officer is no longer an employee at the end of the three-year period. The TSR PRSUs are valued using a Monte Carlo simulation model. The number of units expected to be earned, based upon the achievement of the TSR market condition, is factored into the grant date Monte Carlo valuation. Compensation expense is recognized on a straight-line basis over the three-year service period. Compensation expense is recognized regardless of the eventual number of units that are earned based upon the market condition, provided the executive officer remains an employee at the end of the three-year period. Compensation expense is reversed if the executive officer is not an employee at the end of the three-year service period. During

the nine months ended September 28, 2014, Teradyne granted 0.1 million TSR performance-based restricted stock unit awards with an estimated grant date fair value of $22.06 per award. The fair value was estimated using the Monte Carlo simulation model with the following assumptions:

|  | For the Nine Months Ended |
|  | September 28, 2014 |
Risk-free interest rate |  |  | 0.75 | %
Teradyne volatility-historical |  |  | 36.1 | %
Philadelphia Semiconductor Index volatility-historical |  |  | 24.6 | %
Dividend yield |  |  | 1.25 | %

Expected volatility was based on the historical volatility of Teradyne’s stock and the Philadelphia Semiconductor Index over the most recent three-year period. The risk-free interest rate was determined using the U.S. Treasury yield curve in effect at the time of grant. Dividend yield was based upon an estimated annual dividend amount of $0.24 per share divided by Teradyne’s January 24, 2014 stock price of $19.16.

During the nine months ended September 28, 2014, Teradyne granted 1.7 million of service-based restricted stock unit awards to employees at a weighted average grant date fair value of $19.09 and 0.1 million of service-based stock options to executive officers at a weighted average grant date fair value of $5.49.

During the nine months ended September 29, 2013, Teradyne granted 1.9 million of service-based 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.

Restricted stock unit awards granted to employees vest in equal annual installments over four years. Stock options vest in equal annual installments over four years, and have a term of seven years from the date of grant.

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

|  | For the Nine Months Ended |
|  | September 28, 2014 |  |  | September 29, 2013 |
Expected life (years) |  |  | 4.0 |  |  |  | 4.0 |
Risk-free interest rate |  |  | 1.2 | % |  |  | 0.6 | %
Volatility-historical |  |  | 38.8 | % |  |  | 46.8 | %
Dividend yield |  |  | 1.25 | % |  |  | 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 interest rate was determined using the U.S. Treasury yield curve in effect at the time of grant. Dividend yield was based upon an estimated annual dividend amount of $0.24 per share divided by Teradyne’s January 24, 2014 stock price of $19.16.

Effective January 31, 2014, Michael Bradley retired as Chief Executive Officer of Teradyne. Mr. Bradley will continue to serve on Teradyne’s Board of Directors. On January 22, 2014, Teradyne entered into an agreement (the “Retirement Agreement”) with Mr. Bradley. Under the Retirement Agreement, Mr. Bradley’s unvested restricted stock units and stock options granted prior to his retirement date will continue to vest in accordance with their terms through January 31, 2017; and any vested options or options that vest during that period may be exercised for the remainder of the applicable option term. In the Retirement Agreement, Mr. Bradley agreed to be bound by non-competition and non-solicitation restrictions through January 31, 2017. In January 2014, Teradyne recorded a one-time charge to stock-based compensation expense of $6.6 million related to the Retirement Agreement.

| of this calculation, representing the total intrinsic value of the convertible debt, was divided by the average Teradyne stock price for the period from January 1, 2014 to March 12, 2014 and adjusted for the number of days the convertible notes were outstanding. Incremental shares from assumed conversion of the convertible notes for the three and nine months ended September 29, 2013 were calculated using the difference between the average Teradyne stock price for the period the convertible notes were outstanding and the conversion price of $5.48, multiplied by the 34.7 million shares to be issued upon conversion. The result of this calculation, representing the total intrinsic value of the convertible debt, was divided by the average Teradyne stock price for the period.

(2) | Convertible note hedge warrant shares for the three and nine months ended September 28, 2014 are calculated using the difference between the average Teradyne stock price for the period the warrants were outstanding and the warrant price of $7.63 and $7.64, respectively, multiplied by the weighted average warrant shares outstanding. 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 warrants were outstanding. Convertible note hedge warrant shares for the three and nine months ended September 29, 2013 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 nine months ended September 28, 2014 excludes the effect of the potential exercise of stock options to purchase approximately 0.3 million shares because the effect would have been anti-dilutive.

The computation of diluted net income per common share for the three and nine months ended September 29, 2013 excludes the effect of the potential exercise of stock options to purchase approximately 0.4 million shares because the effect would have been anti-dilutive.

Other

During the three and nine months ended September 28, 2014, Teradyne recorded a $0.6 million fair value adjustment to decrease the ZTEC acquisition contingent consideration.

N. Retirement Plans

ASC 715, “Compensation—Retirement Benefits” requires an employer with defined benefit plans or other postretirement benefit plans to recognize an asset or a liability on its balance sheet for the overfunded or underfunded status of the plans as defined by ASC 715. The pension asset or liability represents a difference between the fair value of the pension plan’s assets and the projected benefit obligation.

On October 27, 2014, the U.S. Society of Actuaries released new mortality tables. Teradyne will use the new mortality tables along with other updated pension valuation assumptions (discount rate, asset rate of return, etc.) as part of its annual fourth quarter pension obligation remeasurement. The estimated actuarial loss as a result of the new mortality tables and current discount rates is approximately $50 million.

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. In the nine months ended September 28, 2014, Teradyne contributed $1.3 million to the U.S. supplemental executive defined benefit pension plan and $1.2 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.

For the three and nine months ended September 28, 2014 and September 29, 2013, Teradyne’s net periodic postretirement benefit was comprised of the following:

P. Income Taxes

The effective tax rate for the three months ended September 28, 2014 and September 29, 2013 was 18% and 21%, respectively. The decrease in the tax rate was primarily due to a more favorable geographic mix of income partially offset by an increase in reserves for uncertain tax positions.

The effective tax rate for the nine months ended September 28, 2014 and September 29, 2013 was 16% and 14%, respectively. The increase in the tax rate was primarily due to income tax expense for the nine months ended September 29, 2013 being reduced for a discrete tax benefit from the January 2013 reinstatement of the U.S. research and development credit for fiscal year 2012 and an increase in reserves for uncertain tax positions in fiscal year 2014, partially offset by a more favorable geographic mix of income in fiscal year 2014.

The effective tax rate for each of these periods is lower than the 35% U.S. statutory federal tax rate primarily due to the geographic mix of income and profits earned by Teradyne’s international subsidiaries being taxed at rates lower than the U.S. statutory rate.

As of September 28, 2014, Teradyne had $31.6 million of reserves for uncertain tax positions. As of December 31, 2013, Teradyne had $21.2 million of reserves for uncertain tax positions. The $10.4 million net increase in reserves for uncertain tax positions primarily relates to the allocation of income among jurisdictions. As of September 28, 2014, Teradyne anticipates the liability for uncertain tax positions could decrease by approximately $2.8 million over the next twelve months, primarily as a result of the expiration of statutes of limitations and clarification of tax laws. The potential decrease is primarily related to equity compensation.

Teradyne qualifies for a tax holiday in Singapore by fulfilling the requirements of an agreement with the Singapore Economic Development Board under which certain headcount and spending requirements must be met. The tax savings due to the tax holiday for the nine months ended September 28, 2014 were $12.3 million or $0.05 per diluted share. The tax holiday is currently expected to expire on December 31, 2015.

Q. Segment Information

Teradyne has three operating segments (Semiconductor Test, Wireless Test and System 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 System 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.

Item 2: | Management’s Discussion and Analysis of Financial Condition and Results of Operations

Statements in this Quarterly Report on Form 10-Q which are not historical facts, so called “forward looking statements,” are made pursuant to the safe harbor provisions of Section 21E of the Securities Exchange Act of 1934, as amended. Investors are cautioned that all forward looking statements involve risks and uncertainties, including those detailed in our filings with the Securities and Exchange Commission. See also Part II, Item 1A of this Quarterly Report on Form 10-Q and Part I, Item 1A “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2013. Readers are cautioned not to place undue reliance on these forward-looking statements which reflect management’s analysis only as of the date hereof. We assume no obligation to update these forward-looking statements to reflect actual results or changes in factors or assumptions affecting forward-looking statements, except as may be required by law.

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 (“Production Board Test”) systems (collectively these products represent “System 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 October 2013, we acquired ZTEC Instruments Inc. (“ZTEC”), a supplier of modular wireless test instruments. The acquisition of ZTEC expands our Wireless Test segment into the design verification test of wireless components and chipsets.

In October 2014, we acquired substantially all the assets of Avionics Interface Technologies, LLC, a leading provider of equipment for testing state-of-the-art data buses. The acquisition complements our Mil/Aero business unit’s line of bus test instrumentation so that we can provide complete test solutions for today’s commercial and defense avionics systems.

We will continue to invest in our business to further expand our addressable markets while tightly managing our costs.

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 because our customers often delay or accelerate purchases in reaction to changes in their businesses and to demand fluctuations in the semiconductor and electronics industries. Historically, these demand fluctuations have resulted in significant variations in our results of operations. The sharp swings in the semiconductor and electronics industries in recent years have generally affected the semiconductor and electronics test equipment and services industries more significantly than the overall capital equipment sector.

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 September 28, 2014, we recorded an inventory provision of $6.4 million included in cost of revenues primarily due to downward revisions to previously forecasted demand levels. Of the $6.4 million of total excess and obsolete provisions, $4.4 million was related to Semiconductor Test, $1.3 million was related to Wireless Test, and $0.7 million was related to System Test.

During the three months ended September 29, 2013, we recorded an inventory provision of $3.8 million included in cost of revenues, due to the following factors:

| • |  | A $2.0 million inventory write-down as a result of product transition in Wireless Test.

| • |  | The remainder of the charge of $1.8 million primarily reflects downward revisions to previously forecasted demand levels, of which $1.4 million was related to Semiconductor Test and $0.4 million was related to System Test.

During the three months ended September 28, 2014 and September 29, 2013, we scrapped $11.1 million and $13.9 million of inventory, respectively. During the three months ended September 28, 2014 and September 29, 2013, we sold $6.2 million and $4.1 million, respectively, of previously written-down inventory. As of September 28, 2014, we had inventory related reserves for inventory which had been written-down totaling $116.1 million. We have no pre-determined timeline to scrap the remaining inventory.

Engineering and Development

Engineering and development expenses were as follows:

|  | For the Three Months Ended |  |  | Dollar Change |
|  | September 28, 2014 |  |  | September 29, 2013 |  |
|  | (in millions) |
Engineering and development |  | $ | 72.0 |  |  | $ | 68.9 |  |  | $ | 3.1 |
Percent of total revenue |  |  | 15.1 | % |  |  | 15.9 | % |  |  |  |

The increase of $3.1 million in engineering and development expenses was due primarily to increased spending in Semiconductor Test.

Selling and Administrative

Selling and administrative expenses were as follows:

|  | For the Three Months Ended |  |  | Dollar Change |
|  | September 28, 2014 |  |  | September 29, 2013 |  |

Percent of total revenue |  |  | 15.3 | % |  |  | 16.8 | % |  |  |  |

The increase of $0.2 million in selling and administrative expenses was due primarily to increased sales and marketing spending in Semiconductor Test.

Restructuring and Other

Restructuring

During the three months ended September 28, 2014, we recorded $0.2 million of severance charges related to headcount reductions of 2 people in System Test.

During the three months ended September 29, 2013, we recorded $1.3 million of severance charges related to headcount reductions of approximately 40 people, of which $1.0 million was in System Test and $0.3 million was in Semiconductor Test, and a $(0.4) million credit related to a change in the estimated exit costs related to a leased facility, in Corporate.

Other

During the three months ended September 28, 2014, we recorded a $0.6 million fair value adjustment to decrease the ZTEC acquisition contingent consideration.

Income Taxes

The effective tax rate for the three months ended September 28, 2014 and September 29, 2013 was 18% and 21%, respectively. The decrease in the tax rate was primarily due to a more favorable geographic mix of income partially offset by an increase in reserves for uncertain tax positions.

The effective tax rate for each of these periods is lower than the 35% U.S. statutory federal tax rate primarily due to the geographic mix of income and profits earned by our international subsidiaries being taxed at rates lower than the U.S. statutory rate.

Nine Months of 2014 Compared to Nine Months of 2013

Revenues

Net revenues by reportable segment were as follows:

|  | For the Nine Months Ended |  |  | Dollar Change |
|  | September 28, 2014 |  |  | September 29, 2013 |  |
|  | (in millions) |
Semiconductor Test |  | $ | 1,063.3 |  |  | $ | 808.1 |  |  | $ | 255.2 |
Wireless Test |  |  | 144.7 |  |  |  | 226.1 |  |  |  | (81.4 | )
System Test |  |  | 116.6 |  |  |  | 108.4 |  |  |  | 8.2 |
|  | $ | 1,324.6 |  |  | $ | 1,142.6 |  |  | $ | 182.0 |

The increase in Semiconductor Test revenues of $255.2 million or 32% was primarily due to higher SOC product volume, driven by application processors and microcontrollers. The decrease in Wireless Test revenue of $81.4 million or 36% was primarily due to lower cellular and connectivity product volume. The increase in System Test revenue of $8.2 million or 8% was primarily due to higher product volume in Production Board Test and Storage Test systems, partially offset by lower Mil/Aero product sales.

Gross Profit

Our gross profit was as follows:

|  | For the Nine Months Ended |  |  | Dollar/Point Change |
|  | September 28, 2014 |  |  | September 29, 2013 |  |
|  | (in millions) |
Gross profit |  | $ | 718.6 |  |  | $ | 648.9 |  |  | $ | 69.7 |
Percent of total revenues |  |  | 54.2 | % |  |  | 56.8 | % |  |  | (2.6 | )

Gross profit as a percent of revenue decreased by 2.6 percentage points due primarily to a decrease of 2.4 points related to product mix in SOC Semiconductor Test and lower Wireless Test sales, a decrease of 0.7 point due to higher excess and obsolete inventory provisions, partially offset by higher sales volume.

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 nine months ended September 28, 2014, we recorded an inventory provision of $21.5 million included in cost of revenues with $6.2 million related to product transition in Semiconductor Test and $15.3 million due to downward revisions to previously forecasted demand levels. Of the $21.5 million of total excess and obsolete provisions, $14.3 million was related to Semiconductor Test, $5.2 million was related to Wireless Test, and $2.0 million was related to System Test.

During the nine months ended September 29, 2013, we recorded an inventory provision of $9.6 million included in cost of revenues, due to the following factors:

| • |  | A $4.1 million inventory write-down as a result of product transition in Wireless Test.

| • |  | The remainder of the charge of $5.5 million primarily reflects downward revisions to previously forecasted demand levels, of which $2.0 million was related to Wireless Test, $1.9 million was related to Semiconductor Test and $1.6 million was related to System Test.

During the nine months ended September 28, 2014 and September 29, 2013, we scrapped $14.3 million and $16.8 million of inventory, respectively. During the nine months ended September 28, 2014 and September 29, 2013, we sold $9.8 million and $8.9 million of previously written-down or written-off inventory. As of September 28, 2014, we had inventory related reserves for inventory which had been written-down or written-off totaling $116.1 million. We have no pre-determined timeline to scrap the remaining inventory.

Engineering and Development

Engineering and development expenses were as follows:

|  | For the Nine Months Ended |  |  | Dollar Change |
|  | September 28, 2014 |  |  | September 29, 2013 |  |
|  | (in millions) |

Percent of total revenues |  |  | 16.0 | % |  |  | 17.5 | % |  |  |  |

The increase of $13.1 million in engineering and development expenses was due primarily to increased spending in Semiconductor Test and Wireless Test and higher variable compensation.

Selling and Administrative

Selling and administrative expenses were as follows:

|  | For the Nine Months Ended |  |  | Dollar Change |
|  | September 28, 2014 |  |  | September 29, 2013 |  |
|  | (in millions) |

Percent of total revenue |  |  | 17.3 | % |  |  | 18.4 | % |  |  |  |

The increase of $18.6 million in selling and administrative expenses was due primarily to a one-time $6.6 million stock-based compensation charge related to Michael Bradley’s (retired Chief Executive Officer) Retirement Agreement, increased sales and marketing spending in Semiconductor Test and Wireless Test, and higher variable compensation.

Restructuring and Other

Restructuring

During the nine months ended September 28, 2014, we recorded $0.8 million of severance charges related to headcount reductions of approximately 30 people, primarily in Wireless Test.

During the nine months ended September 29, 2013, Teradyne recorded $1.5 million of severance charges related to headcount reductions of approximately 40 people, of which $1.4 million was in System Test and $0.4 million was in Semiconductor Test, and a $(0.4) million credit in Corporate for a change in the estimated exit costs related to a leased facility.

Other

During the nine months ended September 28, 2014, we recorded a $0.6 million fair value adjustment to decrease the ZTEC acquisition contingent consideration.

Income Taxes

The effective tax rate for the nine months ended September 28, 2014 and September 29, 2013 was 16% and 14%, respectively. The increase in the tax rate was primarily due to income tax expense for the nine months ended September 29, 2013 being reduced for a discrete tax benefit from the January 2013 reinstatement of the U.S. research and development credit for fiscal year 2012 and an increase in reserves for uncertain tax positions in fiscal year 2014, partially offset by a more favorable geographic mix of income in fiscal year 2014.

The effective tax rate for each of these periods is lower than the 35% U.S. statutory federal tax rate primarily due to the geographic mix of income and profits earned by our international subsidiaries being taxed at rates lower than the U.S. statutory rate.

Contractual Obligations

The following table reflects our contractual obligations at September 28, 2014:

|  | Payments Due by Period |

(1) | Included in Long-term other liabilities are liabilities for customer advances, extended warranty, uncertain tax positions, deferred tax liabilities and other obligations. For certain long-term obligations, we are unable to provide a reasonably reliable estimate of the timing of future payments relating to these obligations and therefore we included these amounts in the column marked “Other”.

Liquidity and Capital Resources

Our cash, cash equivalents and marketable securities balances decreased by $18.3 million in the nine months ended September 28, 2014, to $1,181 million. Cash activity for the nine months ended September 28, 2014 and September 29, 2013 was as follows:

##### Table of Contents

In the nine months ended September 28, 2014, changes in operating assets and liabilities used cash of $27.3 million. This was due to a $77.6 million increase in operating assets and a $50.3 million increase in operating liabilities.

The increase in operating assets was due to a $163.7 million increase in accounts receivable due to higher sales and increase in days sales outstanding (“DSO”). DSO for the three months ended September 28, 2014 was 61 days as compared to December 31, 2013 DSO of 50 days. The increase in accounts receivable was partially offset by a $47.8 million decrease in prepayments and other assets and a $38.3 million decrease in inventories due to higher sales. The increase in operating liabilities was due to a $52.2 million increase in other accrued liabilities, a $14.3 million increase in customer advance payments and deferred revenue and a $10.2 million increase in accrued income taxes, partially offset by a $16.2 million decrease in accrued employee compensation due primarily to variable compensation and employee stock award payroll tax payments, a $4.3 million convertible note interest payment, $3.3 million of retirement plan contributions and a $2.6 million decrease in accounts payable. Based on the new mortality tables released on October 27, 2014 and current discount rates, we estimate the funded status of our U.S. Qualified Pension Plan (the “Plan”) to be approximately 91%. During the fourth quarter of 2014, we plan to contribute approximately $30.0 million to the Plan to bring the Plan back to being fully funded.

Investing activities during the nine months ended September 28, 2014 used cash of $254.4 million, due to $844.1 million used for purchases of marketable securities and $146.4 million used for purchases of property, plant and equipment, partially offset by proceeds from maturities and sales of marketable securities that provided cash of $495.6 million and $236.1 million, respectively, and proceeds from life insurance of $4.4 million related to the cash surrender value from the cancellation of Teradyne owned life insurance policies on its retired chief executive officer. The increase in purchases of property, plant and equipment of $63.4 million compared to the nine months ended September 29, 2013 is primarily due to testers used for customer leases.

Financing activities during the nine months ended September 28, 2014 used cash of $192.6 million. $191.0 million of cash was used for payments on long-term debt related to the convertible note and the Japan loan and $24.4 million was used for dividend payments, partially offset by $21.0 million provided by the issuance of common stock under employee stock purchase and stock option plans and $1.7 million from the tax benefit related to stock options and restricted stock units.

In the nine months ended September 29, 2013, changes in operating assets and liabilities used cash of $47.2 million. This was due to a $48.1 million increase in operating assets and a $0.9 million increase in operating liabilities.

The increase in operating assets was due to a $56.0 million increase in accounts receivable and a $26.3 million increase in other assets primarily due to an increase in prepayments, partially offset by a $34.2 million decrease in inventories. The increase in operating liabilities was due to an $9.4 million increase in accounts payable, a $13.8 million increase in accrued income taxes and a $9.9 million increase in other accrued liabilities, partially offset by a $19.2 million decrease in accrued employee compensation due primarily to variable compensation and employee stock award payroll tax payments, a $9.2 million decrease in customer advance payments and deferred revenue, and $3.6 million of retirement plan contributions.

Investing activities during the nine months ended September 29, 2013 used cash of $6.6 million, due to $658.6 million used for purchases of marketable securities and $82.9 million used for purchases of property, plant and equipment, partially offset by proceeds from maturities and sales of marketable securities that provided cash of $401.9 million and $333.0 million, respectively.

Financing activities during the nine months ended September 29, 2013 provided cash of $16.1 million, of which $16.8 million was from the issuance of common stock under employee stock purchase and stock option plans and $0.8 million from the tax benefit related to stock options and restricted stock units, partially offset by $1.1 million of cash used for the payments on long-term debt related to the Japan loan and $0.4 million of cash used for payments related to LitePoint acquisition contingent consideration.

Holders of our common stock are entitled to receive dividends if and when they are declared by our Board of Directors. In January 2014, our Board of Directors declared an initial quarterly cash dividend of $0.06 per share that was paid on June 2, 2014 to stockholders of record as of May 9, 2014. In August 2014, our Board of Directors declared a quarterly cash dividend of $0.06 per share that was paid on September 26, 2014 to stockholders of record as of September 5, 2014. Total dividend payments in the nine months ended September 28, 2014 were $24.4 million. Payment of future cash dividends will rest within the discretion of our Board of Directors and will depend, among other things, upon our earnings, capital requirements and financial condition.

In 2014, we deployed approximately $75 million of capital into testers for customer leases bringing our total forecasted 2014 capital additions to $169 million.

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 $460 million of cash, cash equivalents and marketable securities 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 O: “Stock Based Compensation” in our 2013 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

On July 18, 2013, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“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. Our implementation of this ASU did not have a material impact on our financial position and results of operations.

In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers (Topic 606)” which will replace numerous requirements in U.S. GAAP, including industry-specific requirements, and provide companies with a single revenue recognition model for recognizing revenue from contracts with customers. The core principle of the new standard is that a company should recognize revenue to show the transfer of promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. The new standard will be effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. For Teradyne, the standard will be effective in the first quarter of 2017. The two permitted transition methods under the new standard are the full retrospective method, in which case the standard would be applied to each prior reporting period presented, or the modified retrospective method, in which case the cumulative effect of applying the standard would be recognized at the date of initial application. We have not yet selected a transition method. We are currently evaluating the impact of this ASU on our financial position and 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 February 28, 2014. 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, 2013.

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.
