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 statement of such interim financial statements. Certain prior year amounts may have been reclassified to conform to the current year presentation. The December 31, 2022 condensed consolidated balance sheet data was derived from audited financial statements but does not include all disclosures required by United States of America generally accepted accounting principles (“U.S. GAAP”) for complete financial statements. 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 22, 2023, for the year ended December 31, 2022.

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 of assets, liabilities, revenues and expenses, and related disclosures of contingent liabilities. On an on-going basis, management evaluates its estimates, including those related to inventories, investments, goodwill, intangible and other long-lived assets, accounts receivable, income taxes, deferred tax assets and liabilities, pensions, warranties, contingent consideration liabilities, and loss contingencies. Management bases its estimates on historical experience and on appropriate and customary assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgements about the carrying values of assets and liabilities that are not readily apparent from other sources. Management is not aware of any specific event or circumstance that would require an update to its estimates or judgments or a revision of the carrying value of its assets or liabilities as of the date of issuance of this Quarterly Report on Form 10-Q. These estimates may change, as new events occur and additional information is obtained. Actual results may differ significantly from these estimates under different assumptions or conditions.

C. RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

For the nine months ended October 1, 2023, there were no recently issued accounting pronouncements that had, or are expected to have, a material impact to Teradyne’s consolidated financial statements.

Derivatives

Teradyne conducts business in various foreign countries, with certain transactions denominated in local currencies. As a result, Teradyne is exposed to risks relating to changes in foreign currency exchange rates. Teradyne’s foreign currency risk management objective is to minimize the effect of exchange rate fluctuations associated with the remeasurement of monetary assets and liabilities denominated in foreign currencies, and changes in its cash inflows attributable to the forecasted cash flows from certain foreign currency denominated revenues.

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 monetary assets and liabilities denominated in foreign currencies.

Teradyne also enters into foreign currency forward and option contracts designated as cash flow hedges to hedge the risk of changes in its cash inflows attributable to changes in foreign currency exchange rates. The cash flow hedges have maturities of less than six months and mature in the period of revenue recognition for certain products and services in backlog and forecasted to be recognized in a future period. Teradyne evaluates cash flow hedges for effectiveness at inception based on the critical terms match method. The hedges are not expected to incur any ineffectiveness however a quarterly qualitative assessment of effectiveness is done to determine if the critical terms match method remains appropriate to use. The change in fair value of the contracts is recorded in accumulated other comprehensive income (loss) and reclassified to earnings at maturity date.

Teradyne does not use derivative financial instruments for speculative purposes.

G. DEBT

Convertible Senior Notes

On December 12, 2016, Teradyne completed a private offering of $460.0 million aggregate principal amount of 1.25% convertible senior unsecured notes (the “Notes”) due December 15, 2023 and received net proceeds, after issuance costs, of approximately $450.8 million, $33.0 million of which was used to pay the net cost of the convertible note hedge transactions and $50.1 million of which was used to repurchase 2.0 million shares of Teradyne’s common stock under its existing stock repurchase program from purchasers of the Notes in privately negotiated transactions effected through one of the initial purchasers or its affiliates conducted concurrently with the pricing of the Note offering. The Notes will mature on December 15, 2023, unless earlier repurchased or converted. The Notes bear interest at a rate of 1.25% per year payable semiannually in arrears on June 15 and December 15 of each year. The Notes will be convertible at the option of the noteholders at any time prior to the close of business on the business day immediately preceding September 15, 2023, only under the following circumstances: (1) during any calendar quarter beginning after March 31, 2017 (and only during such calendar quarter), if the closing sale price of Teradyne’s common stock, for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on the last trading day of the immediately preceding calendar quarter is greater than 130% of the conversion price on each applicable trading day; (2) during the five business day period after any five consecutive trading day period (the “measurement period”) in which the trading price (as defined in the Indenture) per $1,000 principal amount of Notes for each trading day of the measurement period was less than 98% of the product of the closing sale price of the Teradyne’s common stock and the conversion rate on each such trading day; and (3) upon the occurrence of specified corporate events. On or after September 15, 2023, until the close of business on the second scheduled trading day immediately preceding the maturity date, holders may convert their Notes at any time, regardless of the foregoing circumstances. Teradyne may satisfy its future conversion obligation by paying cash for the principal amount of the Notes and paying or delivering cash, shares of its common stock or a combination of cash and shares of its common stock, at Teradyne’s election for the amount in excess of principal. On November 4, 2021, Teradyne made an irrevocable election under the Indenture to require the principal portion of the remaining Notes to be settled in cash. As of October 1, 2023, the conversion price was approximately $31.41 per share of Teradyne’s common stock. The conversion rate is subject to adjustment under certain circumstances. As of November 3, 2023, one hundred and thirty-five debt holders had exercised the option to convert $436.5 million worth of notes.

Concurrent with the offering of the Notes, Teradyne entered into convertible note hedge transactions (the “Note Hedge Transactions”) with the initial purchasers or their affiliates (the “Option Counterparties”). The Note Hedge Transactions cover, subject to customary anti-dilution adjustments, the number of shares of the common stock that underlie the Notes, with a strike price equal to the conversion price of the Notes of $31.41.

Separately and concurrent with the pricing of the Notes, Teradyne entered into warrant transactions with the Option Counterparties (the “Warrant Transactions”) in which it sold net-share-settled (or, at its election subject to certain conditions, cash-settled) warrants to the Option Counterparties. These transactions have been accounted for as an adjustment to our shareholders’

14

equity. The Warrant Transactions currently cover, subject to customary anti-dilution adjustments, approximately 14.6 million shares of common stock. As of October 1, 2023, the strike price of the warrants was approximately $39.42 per share. The strike price is subject to adjustment under certain circumstances. The Warrant Transactions could have a dilutive effect to Teradyne’s common stock to the extent that the market price per share of Teradyne’s common stock, as measured under the terms of the Warrant Transactions, exceeds the applicable strike price of the warrants.

The Note Hedge Transactions are expected to reduce the potential dilution to Teradyne’s common stock upon any conversion of the Notes. However, the Warrant Transactions could separately have a dilutive effect to the extent that the market value per share of Teradyne’s common stock exceeds the applicable strike price of the warrant. The net cost of the Note Hedge Transactions, after being partially offset by the proceeds from the sale of the warrants, was approximately $33.0 million.

In connection with establishing their initial hedge of these convertible note hedge and warrant transactions, the Option Counterparties have entered into various derivative transactions with respect to Teradyne’s common stock and/or purchased shares of Teradyne’s common stock or other securities, including the Notes, concurrent with, or shortly after, the pricing of the Notes. In addition, the Option Counterparties may modify their hedge positions by entering into or unwinding various derivative transactions with respect to Teradyne’s common stock or by selling Teradyne’s common stock or other securities, including the Notes, in secondary market transactions (and may do so during any observation period related to the conversion of the Notes). These activities could adversely affect the value of Teradyne’s common stock and the Notes.

Originally, Teradyne allocated $100.8 million of the $460.0 million principal amount of the Notes to the equity component, which represented a discount to the debt and was amortized to interest expense using the effective interest method through December 2023. Effective January 1, 2022, Teradyne adopted ASC 2020-06 using the modified retrospective method of transition and accounts for the debt as a single liability measured at its amortized cost. As a result of the adoption, Teradyne recorded an increase of $1.4 million to current debt for unsettled shares, an increase of $1.8 million to deferred tax assets, an increase of $6.6 million to long-term debt for unamortized debt discount, and an increase to retained earnings of $94.6 million for the reclassification of the equity component. Mezzanine equity representing unsettled shares value was reduced to zero and additional paid-in capital was reduced by $100.8 million.

Debt issuance fees at October 1, 2023, have been fully amortized to interest expense using the effective interest method over the seven-year term of the Notes.

Revolving Credit Facility

On May 1, 2020, Teradyne entered into a credit agreement (the “Credit Agreement”) with Truist Bank, as administrative agent and collateral agent, and the lenders party thereto. The Credit Agreement provided for a three-year, senior secured revolving credit facility of $400.0 million (the “Credit Facility”).

On December 10, 2021, the Credit Agreement was amended to extend the maturity date of the Credit Facility to December 10, 2026. On October 5, 2022, the Credit Agreement was amended to increase the amount of the Credit Facility to $750.0 million from $400.0 million.

The Credit Agreement provides that, subject to customary conditions, Teradyne may seek to obtain from existing or new lenders the available incremental amount under the Credit Facility, not to exceed the greater of $200.0 million or 15% of consolidated EBIDTA. The interest rate applicable to loans under the Credit Facility are, at Teradyne’s option, equal to either a base rate plus a margin ranging from 0.00% to 0.75% per annum or SOFR plus a margin ranging from 1.10% to 1.85% per annum, based on the consolidated leverage ratio of Teradyne. In addition, Teradyne will pay a commitment fee on the unused portion of the commitments under the Credit Facility ranging from 0.15% to 0.25% per annum, based on the then applicable consolidated leverage ratio.

Teradyne is not required to repay any loans under the Credit Facility prior to maturity, subject to certain customary exceptions. Teradyne is permitted to prepay all or any portion of the loans under the Credit Facility prior to maturity without premium or penalty, other than customary SOFR breakage costs.

The Credit Agreement contains customary events of default, representations, warranties and affirmative and negative covenants that, among other things, limit Teradyne’s ability to sell assets, grant liens on assets, incur other secured indebtedness and make certain investments and restricted payments, all subject to exceptions set forth in the Credit Agreement. The Credit Agreement also requires Teradyne to satisfy two financial ratios measured as of the end of each fiscal quarter: a consolidated leverage ratio and an interest coverage ratio.

The Credit Facility is guaranteed by certain of Teradyne’s domestic subsidiaries and collateralized by assets of Teradyne and such subsidiaries, including a pledge of 65% of the capital stock of certain foreign subsidiaries.

As of November 3, 2023, the Credit Agreement was undrawn and Teradyne was in compliance with all covenants under the Credit Agreement.

J. STOCK-BASED COMPENSATION

On February 1, 2023 (the “Retirement Date”), Mark E. Jagiela retired as Chief Executive Officer of Teradyne and a member of Teradyne’s Board of Directors, and Teradyne entered into an agreement (the “Retirement Agreement”) with Mr. Jagiela. Under the Retirement Agreement, Mr. Jagiela’s unvested time-based restricted stock units and stock options granted prior to his Retirement Date were modified to allow continued vesting; and any vested options or options that vest during that period may be exercised for the remainder of the applicable option term. During the nine months ended October 1, 2023, Teradyne recorded a stock-based compensation expense of $5.9 million related to the Retirement Agreement.

Under Teradyne’s stock compensation plans, Teradyne grants time-based restricted stock units, performance-based restricted stock units and stock options, and employees are eligible to purchase Teradyne’s common stock through its Employee Stock Purchase Plan (“ESPP”).

Service-based restricted stock unit awards granted to employees vest in equal annual installments over four years. Restricted stock unit awards granted to non-employee directors vest after a one-year period, with 100% of the award vesting on the earlier of (a) the first anniversary of the grant date or (b) the date of the following year’s Annual Meeting of Shareholders. Teradyne expenses the cost of the restricted stock unit awards subject to time-based vesting, which is determined to be the fair market value of the shares at the date of grant, ratably over the period during which the restrictions lapse.

Performance-based restricted stock units (“PRSUs”) granted to Teradyne’s executive officers may have a performance metric based on relative total shareholder return (“TSR”). Teradyne’s three-year TSR performance is measured against the New York Stock Exchange (“NYSE”) Composite Index. The final number of TSR PRSUs that vest will vary based upon the level of performance achieved from 0% to 200% of the target shares. The TSR PRSUs will vest upon the three-year anniversary of the grant date. 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 shorter of the three-year service period or the period from the grant to the date described in the retirement provisions below. Compensation expense for executive officers meeting the retirement provisions prior to the grant date is recognized during the year following the grant. 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.

17

Compensation expense is reversed if at any time during the three-year service period the executive officer is no longer an employee, subject to the retirement and termination eligibility provisions noted below.

PRSUs granted to Teradyne’s executive officers may also have a performance metric based on three-year cumulative non-GAAP profit before interest and tax (“PBIT”) as a percent of Teradyne’s revenue. Non-GAAP PBIT is a financial measure equal to GAAP income from operations less restructuring and other, net; amortization of acquired intangible assets; acquisition and divestiture related charges or credits; pension actuarial gains and losses; non-cash convertible debt interest expense; and other non-recurring gains and charges. The final number of PBIT PRSUs that vest will vary based upon the level of performance achieved from 0% to 200% of the target shares. The PBIT PRSUs will vest upon the three-year anniversary of the grant date. Compensation expense is recognized on a straight-line basis over the shorter of the three-year service period or the period from the grant date to the date described in the retirement provisions below. Compensation expense for executive officers meeting the retirement provisions prior to the grant date is recognized during the year following the grant. Compensation expense is recognized based on the number of units that are earned based upon the three-year Teradyne PBIT as a percent of Teradyne’s revenue, provided the executive officer remains an employee at the end of the three-year period subject to the retirement and termination eligibility provisions noted below.

If a PRSU recipient’s employment ends prior to the determination of the performance percentage due to (1) permanent disability or death or (2) retirement or termination other than for cause, after attaining both at least age sixty and at least ten years of service, then all or a portion of the recipient’s PRSUs (based on the actual performance percentage achieved on the determination date) will vest on the date the performance percentage is determined. Except as set forth in the preceding sentence, no PRSUs will vest if the executive officer is no longer an employee at the end of the three-year period. Stock options to purchase Teradyne’s common stock at 100% of the fair market value on the grant date vest in equal annual installments over four years from the grant date and have a maximum term of seven years.

During the nine months ended October 1, 2023 and October 2, 2022, Teradyne granted 0.5 million and 0.4 million of service-based restricted stock unit awards to employees at a weighted average grant date fair value of $102.66 and $110.34, respectively, and 0.1 million of service-based restricted stock unit awards to non-employee directors at a weighted average grant date fair value of $90.50 and $106.91, respectively.

During the nine months ended October 1, 2023 and October 2, 2022, Teradyne granted 0.1 million of PBIT PRSUs with a grant date fair value of $102.91 and $110.84, respectively.

During the nine months ended October 1, 2023 and October 2, 2022, Teradyne granted 0.1 million of TSR PRSUs, with a grant date fair value of $139.04 and $101.06, respectively. The fair value was estimated using the Monte Carlo simulation model with the following assumptions:

|  | For the Nine Months Ended |
|  | October 1, 2023 |  |  | October 2, 2022 |
Risk-free interest rate |  |  | 4.0 | % |  |  | 1.4 | %
Teradyne volatility-historical |  |  | 49.7 | % |  |  | 47.1 | %
NYSE Composite Index volatility-historical |  |  | 24.1 | % |  |  | 22.7 | %
Dividend yield |  |  | 0.4 | % |  |  | 0.4 | %

Expected volatility was based on the historical volatility of Teradyne’s stock and the NYSE Composite 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 $0.44 per share divided by Teradyne’s stock price on the grant date of $104.12, and an estimated annual dividend amount of $0.44 per share divided by Teradyne’s stock price on the grant date of $112.12 for the 2022 grant.

During the nine months ended October 1, 2023 and October 2, 2022, Teradyne granted 0.1 million of service-based stock options to executive officers at a weighted average grant date fair value of $41.23 and $39.01, respectively.

18

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

|  | For the Nine Months Ended |
|  | October 1, 2023 |  |  | October 2, 2022 |
Expected life (years) |  |  | 4.0 |  |  |  | 4.0 |
Risk-free interest rate |  |  | 3.8 | % |  |  | 1.6 | %
Volatility-historical |  |  | 46.6 | % |  |  | 43.7 | %
Dividend yield |  |  | 0.4 | % |  |  | 0.4 | %

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 $0.44 per share divided by Teradyne’s stock price on the grant date of $104.15 for the 2023 grant and an estimated annual dividend amount of $0.44 per share divided by Teradyne’s stock price on the grant date of $112.12 for the 2022 grant.

L. GOODWILL AND ACQUIRED INTANGIBLE ASSETS

Goodwill

Teradyne performs its annual goodwill impairment test as required under the provisions of ASC 350-10, “Intangibles—Goodwill and Other” on December 31 of each fiscal year unless interim indicators of impairment exist. In the nine months ended October 1, 2023, there were no interim indicators of impairment. Goodwill is considered impaired when the net book value of a reporting unit exceeds its estimated fair value.

The changes in the carrying amount of goodwill by reportable segments for the nine months ended October 1, 2023, were as follows:

Intangible Assets

Teradyne reviews long-lived assets for impairment whenever events or changes in business circumstances indicate that the carrying amount of the assets may not be fully recoverable or that the useful lives of these assets are no longer appropriate.

Amortizable intangible assets consist of the following and are included in intangible assets, net on the balance sheet:

|  | Gross Carrying Amount (1) |  |  | Accumulated Amortization (1) |  |  | Foreign Currency Translation Adjustment |  |  | Net Carrying Amount |

(1)
In 2023, $9.3 million of amortizable intangible assets became fully amortized and have been eliminated from the gross carrying amount and accumulated amortization.

Aggregate intangible asset amortization expense was $4.7 million and $14.3 million, respectively, for the three and nine months ended October 1, 2023, and $4.7 million and $14.7 million, respectively, for the three and nine months ended October 2, 2022.

Estimated intangible asset amortization expense for each of the five succeeding fiscal years and thereafter is as follows:

Net income per common share-diluted |  | $ | 0.78 |  |  | $ | 1.10 |  |  | $ | 2.01 |  |  | $ | 3.17 |

(1)
Convertible notes hedge warrant shares were calculated using the difference between the average Teradyne stock price for the period and the warrant price, multiplied by the number of warrant shares. The result of this calculation, representing the total intrinsic value of the warrant, was divided by the average Teradyne stock price for the period.
(2)
Incremental shares from assumed conversion of the convertible notes were calculated using the difference between the average Teradyne stock price for the period and the conversion price, multiplied by the number of convertible notes shares. The result of this calculation, representing the total intrinsic value of the convertible notes, was 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 October 1, 2023, excludes the effect of the potential vesting of 0.1 million and 0.4 million, respectively, of restricted stock units because the effect would have been anti-dilutive.

The computation of diluted net income per common share for the three and nine months ended October 2, 2022, excludes the effect of the potential vesting of 0.7 million and 0.9 million, respectively, of restricted stock units because the effect would have been anti-dilutive.

N. RESTRUCTURING AND OTHER

During the three months ended October 1, 2023, Teradyne recorded $4.7 million of severance charges related to headcount reductions of 94 people primarily in Semiconductor Test and Robotics, which included charges related to a voluntary early retirement program for employees meeting certain conditions, and a $1.5 million contract termination charge.

During the three months ended October 2, 2022, Teradyne recorded $1.2 million of severance charges primarily in Robotics and $0.7 million for an increase in legal liabilities.

During the nine months ended October 1, 2023, Teradyne recorded $11.8 million of severance charges related to headcount reductions of 197 people primarily in Semiconductor Test and Robotics, which included charges related to a voluntary early retirement program for employees meeting certain conditions, a $1.5 million contract termination charge, and a charge of $1.1 million for an increase in environmental liability.

During the nine months ended October 2, 2022, Teradyne recorded a charge of $14.7 million related to the arbitration claim filed against Teradyne and AutoGuide related to an earn-out dispute, which was settled on March 25, 2022 for $26.7 million, a charge of $2.7 million for an increase in environmental and legal liabilities, and $2.1 million of severance charges primarily in Robotics.

O. 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 at December 31. Teradyne uses a December 31 measurement date for all its plans.

22

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 the U.S. qualified pension plan 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 (the “IRC”), as well as unfunded qualified foreign plans.

In the nine months ended October 1, 2023 and October 2, 2022, Teradyne contributed $2.3 million and $2.5 million, respectively, to the U.S. supplemental executive defined benefit pension plan, and $0.8 million and $0.7 million, respectively, to certain qualified pension plans for non-U.S. subsidiaries.

For the three and nine months ended October 1, 2023 and October 2, 2022, Teradyne’s net periodic pension cost was comprised of the following:

Postretirement Benefit Plan

In addition to receiving pension benefits, Teradyne employees in the United States who meet early retirement eligibility requirements as of their termination dates may participate in Teradyne’s Welfare Plan, which includes 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. During the three and nine months ended October 1, 2023, Teradyne recorded special termination benefit charges associated with a voluntary early retirement program.

P. COMMITMENTS AND CONTINGENCIES

Purchase Commitments

As of October 1, 2023, Teradyne had entered into purchase commitments for certain components and materials. The purchase commitments covered by the agreements aggregate to approximately $465.8 million, of which $400.2 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 such as, but not limited to, patent, employment, commercial and environmental matters. Teradyne believes that it has meritorious defenses against all pending claims and intends to vigorously contest them. While it is not possible to predict or determine the outcomes of any pending claims or to provide possible ranges of losses that may arise, Teradyne believes the potential losses associated with all of these actions are unlikely to have a material adverse effect on its business, financial position or results of operations.

On March 8, 2021, Industrial Automation LLC, sellers of AutoGuide, submitted a demand for arbitration against Teradyne and AutoGuide in Wilmington, Delaware alleging that Teradyne and AutoGuide breached certain provisions of the Membership Interests Purchase Agreement (the “Purchase Agreement”), dated as of October 18, 2019, among Industrial Automation LLC, Teradyne and AutoGuide. The arbitration demand sought full acceleration of the maximum earn-out amount payable under the Purchase Agreement, or $106.9 million, for the alleged breach of the earn-out provisions of the Purchase Agreement. On March 25, 2022, the arbitration claim was settled for $26.7 million. As a result, Teradyne has no remaining earn-out obligations.

Guarantees and Indemnification Obligations

Teradyne provides indemnification, to the extent permitted by law, to its officers, directors, employees and agents for liabilities arising from certain events or occurrences, while the officer, director, employee, or agent, is or was serving, at Teradyne’s request in such capacity. Teradyne may enter into indemnification agreements with certain of its officers and directors. With respect to acquisitions, Teradyne provides indemnifications to or assumes indemnification obligations for the current and former directors, officers and employees of the acquired companies in accordance with the acquired companies’ by-laws and charter. As a matter of practice, Teradyne has maintained directors’ and officers’ liability insurance coverage including coverage for directors and officers of acquired companies.

Teradyne enters into agreements in the ordinary course of business with customers, resellers, distributors, integrators and suppliers. Most of these agreements require Teradyne to defend and/or indemnify the other party against intellectual property infringement claims brought by a third party with respect to Teradyne’s products. From time to time, Teradyne also indemnifies customers and business partners for damages, losses and liabilities they may suffer or incur relating to personal injury, personal property damage, product liability, breach of confidentiality obligations and environmental claims relating to the use of Teradyne’s products and services or resulting from the acts or omissions of Teradyne, its employees, authorized agents or subcontractors. On occasion, Teradyne has also provided guarantees to customers regarding the delivery and performance of its products in addition to the warranty described below.

As a matter of ordinary course of business, Teradyne warrants that its products will substantially perform in accordance with its standard published specifications in effect at the time of delivery. Most warranties have a one-year duration commencing from installation. A provision is recorded upon revenue recognition to cost of revenues for estimated warranty expense based upon historical experience. When Teradyne receives revenue for extended warranties beyond the standard duration, the revenue is deferred and recognized on a straight-line basis over the contract period. Related costs are expensed as incurred. As of October 1, 2023 and

24

December 31, 2022, Teradyne had a product warranty accrual of $14.7 million and $14.2 million, respectively, included in other accrued liabilities and revenue deferrals related to extended warranties of $38.8 million and $56.2 million, respectively, included in short and long-term deferred revenue and customer advances.

In addition, in the ordinary course of business, Teradyne provides minimum purchase guarantees to certain vendors to ensure continuity of supply against the market demand. Although some of these guarantees provide penalties for cancellations and/or modifications to the purchase commitments as the market demand decreases, most of the guarantees do not. Therefore, as the market demand decreases, Teradyne re-evaluates these guarantees and determines what charges, if any, should be recorded.

With respect to its agreements covering product, business or entity divestitures and acquisitions, Teradyne provides certain representations, warranties and covenants to purchasers and agrees to indemnify and hold such purchasers harmless against breaches of such representations, warranties and covenants. Many of the indemnification claims have a definite expiration date while some remain in force indefinitely. With respect to its acquisitions, Teradyne may, from time to time, assume the liability for certain events or occurrences that took place prior to the date of acquisition.

As a matter of ordinary course of business, Teradyne occasionally guarantees certain indebtedness obligations of its subsidiary companies, limited to the borrowings from financial institutions, purchase commitments to certain vendors and lease commitments to landlords.

Based on historical experience and information known as of October 1, 2023 and December 31, 2022, except for product warranty, Teradyne has not recorded any liabilities for these guarantees and obligations because the amount would be immaterial.

On a quarterly basis, Teradyne evaluates the realizability of the deferred tax assets by jurisdiction and assesses the need for a valuation allowance. As of October 1, 2023, Teradyne believes that it will ultimately realize the deferred tax assets recorded on the condensed consolidated balance sheet. However, should Teradyne believe that it is more-likely-than-not that the deferred tax assets would not be realized, the tax provision would increase in the period in which Teradyne determined that the realizability was not likely. Teradyne considers the probability of future taxable income and historical profitability, among other factors, in assessing the realizability of the deferred tax assets.

As of October 1, 2023 and December 31, 2022, Teradyne had $16.5 million and $15.6 million, respectively, of reserves for uncertain tax positions. The $0.9 million net increase in reserves for uncertain tax positions is related to U.S. federal research and development credits generated in the current year.

As of October 1, 2023, Teradyne estimates that it is reasonably possible that the balance of unrecognized tax benefits may decrease approximately $0.1 million in the next twelve months because of a lapse of statutes of limitation. The estimated decrease relates to U.S. state research and development credits.

Teradyne recognizes interest and penalties related to income tax matters in income tax expense. As of October 1, 2023 and December 31, 2022, $0.6 million and $0.4 million, respectively, of interest and penalties were accrued for uncertain tax positions. For the nine months ended October 1, 2023 and October 2, 2022, an expense of $0.2 million and $0.1 million, respectively, was recorded for interest and penalties related to income tax items.

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 October 1, 2023, was $1.7 million, or $0.01 per diluted share. The tax savings due to the tax holiday for the

25

nine months ended October 2, 2022, was $9.7 million, or $0.05 per diluted share. In November 2020, Teradyne entered into an agreement with the Singapore Economic Development Board which extended our Singapore tax holiday under substantially similar terms to the agreement which expired on December 31, 2020. The new tax holiday is scheduled to expire on December 31, 2025.

On August 16, 2022, the Inflation Reduction Act of 2022 (“IRA”) was signed into law. The IRA introduced a 15% alternative minimum tax based on the financial statement income of certain large corporations (“CAMT”), effective January 1, 2023. Teradyne currently does not expect the CAMT to have a material impact on its financial results.

R. SEGMENT INFORMATION

Teradyne has four reportable segments (Semiconductor Test, System Test, Wireless Test and Robotics). Each of the reportable segments represents an individual operating segment.

The Semiconductor Test segment includes operations related to the design, manufacturing and marketing of semiconductor test products and services. The System Test segment includes operations related to the design, manufacturing and marketing of products and services for defense/aerospace instrumentation test, storage and system level test, and circuit-board test. The Wireless Test segment includes operations related to the design, manufacturing and marketing of wireless test products and services. The Robotics segment includes operations related to the design, manufacturing and marketing of collaborative robotic arms, autonomous mobile robots and advanced robotic control software. Each operating segment has a segment manager who is 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 (loss) 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, 2022.

Segment information for the three and nine months ended October 1, 2023 and October 2, 2022 is as follows:

S. SHAREHOLDERS’ EQUITY

Stock Repurchase Program

In January 2023, Teradyne’s Board of Directors cancelled its January 2021 repurchase program and approved a new repurchase program for up to $2.0 billion of common stock. Teradyne intends to repurchase up to $500.0 million of its common stock in 2023 based on market conditions.

During the nine months ended October 1, 2023, Teradyne repurchased 3.4 million shares of common stock for a total cost of $349.3 million at an average price of $103.89 per share. As of January 1, 2023, share repurchases in excess of issuances are subject to a 1% excise tax, which is included as part of the cost basis of the shares acquired.

During the nine months ended October 2, 2022, Teradyne repurchased 7.2 million shares of common stock for $750.0 million at an average price of $103.83 per share.

The total cost of shares acquired includes commissions and, starting in 2023, related excise tax, and is recorded as a reduction to retained earnings.

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, 2022. 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 automated test equipment and robotics solutions. We design, develop, manufacture and sell automatic test systems and robotics products. Our automatic test systems are used to test semiconductors, wireless products, data storage and complex electronics systems in many industries including the consumer electronics, wireless, automotive, industrial, computing, communications, and aerospace and defense industries. Our robotics products include collaborative robotic arms and autonomous mobile robots (“AMRs”) used by global manufacturing, logistics and industrial customers to improve quality, increase manufacturing and material handling efficiency and decrease manufacturing and logistics costs. Our automatic test equipment and robotics products and services include:

•
semiconductor test (“Semiconductor Test”) systems;
•
storage and system level test (“Storage Test”) systems, defense/aerospace (“Defense/Aerospace”) test instrumentation and systems, and circuit-board test and inspection (“Production Board Test”) systems (collectively these products represent “System Test”);
•
wireless test (“Wireless Test”) systems; and
•
robotics (“Robotics”) products.

The market for our test products is concentrated with a limited number of significant customers accounting for a substantial portion of the purchases of test equipment. A few customers drive significant demand for our test products both through direct sales and sales to the customers’ supply partners. We expect that sales of our test products will continue to be concentrated with a limited number of significant customers for the foreseeable future.

In the third quarter of 2023, the demand in our Semiconductor Test business continued to be impacted by a correction cycle driven by excess semiconductor inventory, primarily in the mobility segment of the market. The depth of this slowdown and the timing of the recovery are uncertain, however, strong automotive and image sensor demand partially offset these declines. The growth of DDR5 and High Bandwidth Memory ("HBM") devices for data center applications continue to drive demand for our products in the memory market. Over the midterm we expect the ramp of 3 nanometer and gate-all-around process technology, increasing multichip packaging, additional device complexity and unit growth will drive additional demand for test.

Our Robotics segment consists of Universal Robots A/S (“UR”), a leading supplier of collaborative robotic arms and Mobile Industrial Robots A/S (“MiR”), a leading maker of AMRs for industrial automation. The market for our Robotics segment products is dependent on the adoption of new automation technologies by large manufacturers as well as small and medium enterprises (“SMEs”) throughout the world. In the third quarter of 2023, Robotics demand stabilized after softening in the first half of 2023 .

In the third quarter of 2023, Robotics and Semiconductor Test shipments came in above our plan. While both our test and robotics businesses could still be impacted by supply constraints, our fourth quarter 2023 forecast does not exclude any revenue due to supply chain constraints.

Our financial statements are denominated in U.S. dollars. While the majority of our revenues are in U.S. dollars, approximately 70 percent of our Robotics revenue is denominated in foreign currencies. In 2022, the strengthening of the U.S. dollar was a factor in lower than forecasted revenues in our Robotics segment. Strengthening of the U.S. dollar would negatively affect Robotics revenue growth in 2023.

Our corporate strategy continues to focus on profitably gaining market share in our test businesses through the introduction of differentiated products that target expanding segments and accelerating growth through continued investment in our Robotics businesses. We plan to execute on our strategy while balancing capital allocations between returning capital to our shareholders through stock repurchases and dividends and using capital for opportunistic accretive acquisitions.

Impact of the Israel-Hamas conflict on our Business

The recent Israel-Hamas conflict could have a negative impact on our future revenue and supply chain, either of which could adversely affect our business and financial results. Our customers in Israel may experience delays in product releases due to impacts to their labor force and impacts on their suppliers because of the conflict, which could materially impact demand for our products. Similarly, our suppliers in Israel may experience delays in providing us with parts due to the conflict. In addition, the global economic uncertainty following the start of the conflict could impact demand for our products.

Supply Chain Constraints and Inflationary Pressures

The global supply shortage of electrical components, including semiconductor chips, impacted our supply chain in the first half of 2023. In the third quarter of 2023, we saw improvements related to supply constraints and, consequently, did not experience material increases in our lead times and costs for components. In addition, while not material, inflationary pressures contributed to increased costs for product components and wage inflation, impacting our cost of products, gross margin and profit for the quarter. Our supply chain team, and our suppliers, continue to manage numerous supply, production, and logistics obstacles. While not material through the third quarter of 2023, in an effort to mitigate these risks, in some cases, we have incurred higher costs due to investment in supply chain resiliency and to secure available inventory or have extended or placed non-cancellable purchase commitments with semiconductor suppliers, which introduces inventory risk if our forecasts and assumptions prove inaccurate. We have also sourced components from additional suppliers and multi-sourced and pre-ordered components and finished goods inventory in some cases in an effort to reduce the impact of the adverse supply chain conditions we have experienced. There is no assurance that these efforts will be successful. While our businesses could still be impacted by supply constraints in the future, our fourth quarter 2023 forecast does not exclude any revenue due to supply chain constraints.

See Part II—Item 1A, “Risk Factors,” included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2022 for our risk factors regarding risks associated with both the supply chain constraints and international conflicts.

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 nine months ended October 1, 2023, 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, 2022, except as noted below.

Critical accounting estimates are complex and may require significant judgment by management. Changes to the underlying assumptions may have a material impact on our financial condition and results of operations. These estimates may change, as new events occur and additional information is obtained. Actual results could differ significantly from these estimates under different assumptions or conditions.

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 under different assumptions or conditions.

Results of Operations

Third Quarter 2023 Compared to Third Quarter 2022

Revenues

Revenues by our reportable segments were as follows:

|  | For the Three Months Ended |  |  |  |
|  | October 1, 2023 |  |  | October 2, 2022 |  |  | Dollar Change |
|  | (in millions) |
Semiconductor Test |  | $ | 497.9 |  |  | $ | 575.7 |  |  | $ | (77.8 | )
System Test |  |  | 83.2 |  |  |  | 116.2 |  |  |  | (33.0 | )
Robotics |  |  | 85.7 |  |  |  | 89.1 |  |  |  | (3.4 | )
Wireless Test |  |  | 37.0 |  |  |  | 46.1 |  |  |  | (9.1 | )
|  | $ | 703.7 |  |  | $ | 827.1 |  |  | $ | (123.4 | )

The decrease in Semiconductor Test revenues of $77.8 million, or 13.5%, was driven primarily by lower tester sales for compute and industrial applications and Memory Test sales in DRAM wafer sort and Flash Final Test. The decrease in System Test revenues of $33.0 million, or 28.4%, was primarily due to lower sales in Storage Test of system level and hard disk drive testers, partially offset by higher sales in Defense/Aerospace. The decrease in Robotics revenues of $3.4 million, or 3.8%, was driven primarily by softening demand due to slowing global industrial activity and macro-economic headwinds, and the impact of the transformation of Universal Robots sales channel. The decrease in Wireless Test revenues of $9.1 million, or 19.7% was primarily due to a decrease in connectivity test products.

Revenues by country as a percentage of total revenues were as follows (1):

|  | For the Three Months Ended |
|  | October 1, 2023 |  |  | October 2, 2022 |

Percent of total revenues |  |  | 14.8 | % |  |  | 13.5 | % |  |  |

The decrease of $7.3 million in engineering and development expenses was primarily due to lower spending in Semiconductor Test and lower variable compensation, partially offset by higher spending in Robotics.

Restructuring and Other

During the three months ended October 1, 2023, we recorded $4.7 million of severance charges related to headcount reductions of 94 people primarily in Semiconductor Test and Robotics, which included charges related to a voluntary early retirement program for employees meeting certain conditions, and a $1.5 million contract termination charge.

During the three months ended October 2, 2022, we recorded $1.2 million of severance charges primarily in Robotics, and a charge of $0.7 million for an increase in legal liabilities.

(1)
Included in Corporate and Eliminations are interest income, interest expense, net foreign exchange gains (losses), intercompany eliminations, legal and environmental fees, contract termination settlement charge and severance charges.

The decrease in income before income taxes in Semiconductor Test was driven primarily by lower tester sales for compute and industrial applications, and Memory Test sales in DRAM wafer sort and flash final test. The decrease in income before income taxes in System Test was primarily due to lower sales in Storage Test of system level and hard disk drive testers. The decrease in income before income taxes in Wireless Test was driven primarily by a decrease in sales of connectivity test products. The decrease in income before income taxes in Robotics was driven primarily by softening demand due to slowing global industrial activity and macro-economic headwinds, the impact of the transformation of Universal Robots sales channel and product mix. The loss before income taxes in Corporate and Eliminations was primarily due to changes in unrealized gains/losses on equity securities.

Income Taxes

The effective tax rate for the three months ended October 1, 2023 and October 2, 2022, was 11.2% and 18.9%, respectively. The decrease in the effective tax rate from the three months ended October 2, 2022, to three months ended October 1, 2023, primarily resulted from an increase in benefit related to tax credits and an increase in benefit related to the international provisions of the U.S. Tax Cuts and Jobs Act of 2017. These decreases were partially offset by an increase in discrete expense related to foreign currency gain or loss.

Nine Months 2023 Compared to Nine Months 2022

Revenues

Revenues by our reportable segments were as follows:

|  | For the Nine Months Ended |  |  |  |
|  | October 1, 2023 |  |  | October 2, 2022 |  |  | Dollar Change |
|  | (in millions) |

|  | $ | 2,005.7 |  |  | $ | 2,423.2 |  |  | $ | (417.5 | )

The decrease in Semiconductor Test revenues of $211.8 million or 13.2%, was driven primarily by lower tester sales for mobility and compute applications. The decrease in System Test revenues of $117.4 million, or 31.8%, was primarily due to lower sales in Storage Test of system level and hard disk drive testers. The decrease in Robotics revenues of $46.3 million, or 15.8%, was driven primarily by softening demand due to slowing global industrial activity and macro-economic headwinds and the impact of the transformation of Universal Robots sales channel. The decrease in Wireless Test revenues of $42.0 million, or 26.0%, was primarily due to a decrease in sales of connectivity test products.

35

The decrease in income before income taxes in Semiconductor Test was driven primarily by lower tester sales for mobility and compute applications. The decrease in income before income taxes in System Test was primarily due to lower sales in Storage Test of system level and hard disk drive testers. The decrease in income before income taxes in Wireless Test was driven primarily by a decrease in sales of connectivity test products. The decrease in income before income taxes in Robotics was driven primarily by softening demand due to slowing global industrial activity and macro-economic headwinds and the impact of the transformation of Universal Robots sales channel. The decrease in loss before income taxes in Corporate and Eliminations was primarily due to legal settlement charges in 2022 related to litigation for the earn-out dispute in connection with the AutoGuide acquisition, changes in unrealized gains/losses on equity securities and higher interest income.

Income Taxes

The effective tax rate for the nine months ended October 1, 2023 and October 2, 2022, was 14.0% and 15.8%, respectively. The decrease in the effective tax rate from the nine months ended October 1, 2023, to the nine months ended October 2, 2022, primarily resulted from an increase in benefit related to tax credits and an increase in benefit related to the international provisions of the U.S. Tax Cuts and Jobs Act of 2017. These decreases were partially offset by a projected shift in the geographic distribution of income, which increases the income subject to taxation in higher tax rate jurisdictions relative to lower tax rate jurisdictions and a reduction in discrete benefit from equity compensation.

Contractual Obligations

There have been no changes outside of the ordinary course of business to our contractual obligations as disclosed in our Annual Report on Form 10-K for the year ended December 31, 2022.

Liquidity and Capital Resources

Our cash, cash equivalents and marketable securities balances decreased by $184.7 million in the nine months ended October 1, 2023, to $820.4 million.

Operating activities during the nine months ended October 1, 2023, provided cash of $336.5 million. Changes in operating assets and liabilities used cash of $119.3 million due to a $27.4 million increase in operating assets and a $91.9 million decrease in operating liabilities.

The increase in operating assets was primarily due to a $64.0 million increase in prepayments and other assets due to prepayments to our contract manufacturers, partially offset by a $30.2 million decrease in accounts receivable and a $6.4 million decrease in inventories.

The decrease in operating liabilities was due to a $56.6 million decrease in accrued employee compensation, a $49.5 million decrease in deferred revenue and customer advance payments, a $42.7 million decrease in income taxes, and $3.7 million of retirement plan contributions, partially offset by a $36.0 million increase in accounts payable, and a $24.5 million increase in other accrued liabilities.

Investing activities during the nine months ended October 1, 2023, used cash of $149.2 million due to $137.8 million used for purchases of marketable securities, $115.3 million used for purchases of property, plant and equipment, and $5.0 million used for issuance of convertible loan, partially offset by $37.0 million and $71.4 million in proceeds from sales and maturities of marketable securities, respectively, and $0.5 million in proceeds from the cancellation of Teradyne owned life insurance policies related to the cash surrender value.

Financing activities during the nine months ended October 1, 2023, used cash of $410.8 million due to $346.5 million used for the repurchase of 3.4 million shares of common stock at an average price of $103.89 per share, $51.1 million used for dividend payments, $26.7 million used for payments of convertible debt principal, and $20.6 million used for payment related to net settlements of employee stock compensation awards, partially offset by $34.1 million from the issuance of common stock under employee stock purchase and stock option plans.

Operating activities during the nine months ended October 2, 2022, provided cash of $394.5 million. Changes in operating assets and liabilities used cash of $271.7 million. This was due to a $158.9 million increase in operating assets and a $112.8 million decrease in operating liabilities.

The increase in operating assets was due to a $94.3 million increase in prepayments and other assets due to prepayments to our contract manufacturers, a $68.8 million increase in inventories, partially offset by a $4.2 million decrease in accounts receivable.

The decrease in operating liabilities was due to a $82.9 million decrease in accrued employee compensation, a $31.4 million decrease in income taxes, a $7.5 million decrease in other accrued liabilities, a $5.9 million decrease in deferred revenue and customer advance payments and $3.9 million of retirement plan contributions, partially offset by an $18.7 million increase in accounts payable.

36

Investing activities during the nine months ended October 2, 2022 provided cash of $45.4 million due to $259.2 million and $182.1 million in proceeds from sales and maturities of marketable securities, respectively, partially offset by $267.2 million used for purchases of marketable securities, and $128.7 million used for purchases of property, plant and equipment.

Financing activities during the nine months ended October 2, 2022 used cash of $858.8 million due to $750.0 million used for the repurchase of 7.2 million shares of common stock at an average price of $103.83 per share, $52.6 million used for dividend payments, $52.0 million used for payments of convertible debt principal, and $33.0 million used for payment related to net settlements of employee stock compensation awards, partially offset by $28.7 million from the issuance of common stock under employee stock purchase and stock option plans.

In January 2023, May 2023, and August 2023, Teradyne’s Board of Directors declared a quarterly cash dividend of $0.11 per share. Dividend payments for the three and nine months ended October 1, 2023, were $16.9 million and $51.1 million, respectively.

In January 2022, May 2022, and August 2022, Teradyne’s Board of Directors declared a quarterly cash dividend to $0.11 per share. Dividend payments for the three and nine months ended October 2, 2022, were $17.1 million and $52.6 million, respectively.

In January 2023, our Board of Directors cancelled the 2021 repurchase program and approved a new repurchase program for up to $2.0 billion of common stock. We intend to repurchase up to $500.0 million of common stock in 2023 subject to market conditions.

During the nine months ended October 1, 2023, we repurchased 3.4 million shares of common stock for $346.5 million, which excludes related excise tax, at an average price of $103.89 per share. During the nine months ended October 2, 2022 , we repurchased 7.2 million shares of common stock for $750.0 million at an average price of $103.83 per share.

While we declared a quarterly cash dividend and authorized a share repurchase program, we may reduce or eliminate the cash dividend or share repurchase program in the future. Future cash dividends and stock repurchases are subject to the discretion of our Board of Directors, which will consider, among other things, our earnings, capital requirements and financial condition.

On May 1, 2020, we entered into a credit agreement providing a three-year, senior secured revolving credit facility of $400 million. On December 10, 2021, the credit agreement was amended to extend the senior secured revolving credit facility to December 10, 2026. On October 5, 2022, the credit agreement was amended to increase the amount of the credit facility to $750.0 million from $400.0 million. As of November 3, 2023, we have not borrowed any funds under the credit facility.

We believe our cash, cash equivalents, marketable securities and senior secured revolving credit facility will be sufficient to pay our quarterly dividend and meet our working capital and expenditure needs for at least the next twelve months. Inflation has not had a significant long-term impact on earnings.

Equity Compensation Plans

In addition to our 1996 Employee Stock Purchase Program as discussed in Note Q: “Stock-Based Compensation” in our 2022 Annual Report on Form 10-K, we have 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 and directors. Both plans were approved by our shareholders.

Recently Issued Accounting Pronouncements

For the nine months ended October 1, 2023, there were no recently issued accounting pronouncements that had, or are expected to have, a material impact to our consolidated financial statements.

Item 3: Quantitative and Qualitative Disclosures about Market Risks

For “Quantitative and Qualitative Disclosures about Market Risk” affecting Teradyne, see Part 2 Item 7A, “Quantitative and Qualitative Disclosures about Market Risks,” in our Annual Report on Form 10-K filed with the SEC on February 22, 2023. There were no material changes in our exposure to market risk from those set forth in our Annual Report on Form 10-K for the fiscal year ended December 31, 2022.

In addition to market risks described in our Annual Report on Form 10-K, we have an equity price risk related to the fair value of our convertible senior unsecured notes issued in December 2016. In December 2016, Teradyne issued $460 million aggregate principal amount of 1.25% convertible senior unsecured notes (the “Notes”) due December 15, 2023. As of October 1, 2023, $23.5 million of principal remained outstanding and the Notes had a fair value of $74.9 million. The table below provides a sensitivity analysis of hypothetical 10% changes of Teradyne’s stock price as of the end of the third quarter of 2023 and the estimated impact on the fair value of the Notes. The selected scenarios are not predictions of future events, but rather are intended to illustrate the effect such event may have on the fair value of the Notes. The fair value of the Notes is subject to equity price risk due to the convertible

37

feature. The fair value of the Notes will generally increase as Teradyne’s common stock price increases and will generally decrease as the common stock price declines in value. The change in stock price affects the fair value of the Notes, but does not impact Teradyne’s financial position, cash flows or results of operations due to the fixed nature of the debt obligation. Additionally, we carry the Notes at face value less unamortized discount on our balance sheet, and we present the fair value for required disclosure purposes only. In connection with the offering of the Notes we also sold warrants to the option counterparties. These transactions have been accounted for as an adjustment to our shareholders’ equity. The convertible notes hedge transactions are expected to reduce the potential equity dilution upon conversion of the Notes. The warrants along with any shares issuable upon conversion of the Notes will have a dilutive effect on our earnings per share to the extent that the average market price of our common stock for a given reporting period exceeds the applicable strike price or conversion price of the warrants or Notes, respectively.

Hypothetical Change in Teradyne Stock Price |  | Fair Value |  |  | Estimated change in fair value |  |  | Hypothetical percentage increase (decrease) in fair value |
10% Increase |  | $ | 82,436 |  |  | $ | 7,517 |  |  |  | 10.0 | %
No Change |  |  | 74,919 |  |  |  | — |  |  |  | — |
10% Decrease |  |  | 67,402 |  |  |  | (7,517 | ) |  |  | (10.0 | )

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) or Rule 15d-15(f) 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.

There have been no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the three months ended October 1, 2023, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

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 such as, but not limited to, patent, employment, commercial and environmental matters. Teradyne believes that it has meritorious defenses against all pending claims and intends to vigorously contest them. While it is not possible to predict or determine the outcomes of any pending claims or to provide possible ranges of losses that may arise, Teradyne believes the potential losses associated with all of these actions are unlikely to have a material adverse effect on its business, financial position or results of operations.

On March 8, 2021, Industrial Automation LLC submitted a demand for arbitration against Teradyne and AutoGuide in Wilmington, Delaware alleging that Teradyne and AutoGuide breached certain provisions of the Membership Interests Purchase Agreement (the “Purchase Agreement”), dated as of October 18, 2019, among Industrial Automation LLC, Teradyne and AutoGuide. The arbitration demand sought full acceleration of the maximum earn-out amount payable under the Purchase Agreement, or $106.9 million, for the alleged breach of the earn-out provisions of the Purchase Agreement. On March 25, 2022, the arbitration claim was settled for $26.7 million. As a result, Teradyne has no remaining earn-out obligations.

Item 1A: Risk Factors

In addition to other information set forth in this Form 10-Q, including the risk discussed below, 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, 2022, 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.

Adverse developments affecting the financial services industry, including events or risks involving liquidity, defaults or non-performance by financial institutions, could have a material adverse effect on our business, financial condition or results of operations.

On March 10, 2023, Silicon Valley Bank (SVB), who is a lender in our revolving credit facility and where we maintain certain accounts and cash deposits, was placed into receivership with the Federal Deposit Insurance Corporation (FDIC), which resulted in all funds held at SVB being temporarily inaccessible by SVB’s customers. As of March 13, 2023, access to our cash and cash equivalents at SVB was fully restored. Although our cash balances at SVB are insignificant and we do not expect further developments at SVB to have a material impact on our cash and cash equivalents, we do hold cash balances in several large financial institutions significantly in excess of FDIC and global insurance limits. If other banks and financial institutions with whom we have banking relationships enter receivership or become insolvent in the future, we may be unable to access, and we may lose, some or all of our existing cash, cash equivalents and investments to the extent those funds are not insured or otherwise protected by the FDIC.

The Israel-Hamas conflict may have a material impact on our Business

The recent Israel-Hamas conflict could have a negative impact on our future revenue and supply chain, either of which could adversely affect our business and financial results. Our customers in Israel may experience delays in product releases due to impacts to their labor force and impacts on their suppliers because of the conflict, which could materially impact demand for our products. Similarly, our suppliers in Israel may experience delays in providing us with parts due to the conflict. In addition, the global economic uncertainty following the start of the conflict could impact demand for our products.

Trade regulations and restrictions impact our ability to manufacture certain products and to sell products to and support certain customers, which may materially adversely affect our sales and results of operations.

We are subject to U.S. laws and regulations that limit and restrict the export of some of our products and services and may restrict our transactions with certain customers, business partners and other persons. In certain circumstances, export control and economic sanctions regulations prohibit the export of certain products, services and technologies, and in other circumstances are required to obtain an export license before exporting the controlled item. We must also comply with export restrictions and laws imposed by other countries affecting trade and investments. We maintain an export compliance program but there are risks that the compliance controls could be circumvented, exposing us to legal liabilities. Compliance with these laws has not significantly limited our sales but could significantly limit them in the future. Changes in, and responses to, U.S. trade policy could reduce the

39

competitiveness of our products and cause our sales to drop, which could have a material adverse effect on our business, financial condition or results of operations.

The U.S. government from time to time has issued export restrictions that prohibit U.S. companies from exporting U.S. manufactured products, foreign manufactured products with more than 25% controlled U.S. content, as well as U.S. origin technology. For example, the U.S. Department of Commerce has restricted the access of U.S. origin technologies to certain Chinese semiconductor companies by adding those companies to the Entity List under U.S. Export Administration Regulations (“EAR”). The addition of certain of these companies to the entity list has had and will continue to have an adverse impact on our business with these customers. We will take appropriate actions, including filing for licenses with the U.S. Department of Commerce to attempt to minimize the impact of the restrictions on our business.

On May 16, 2019, Huawei and 68 of its affiliates, including HiSilicon, were added to the U.S. Department of Commerce Entity List under the EAR. This action by the U.S. Department of Commerce imposed new export licensing requirements on exports, re-exports, and in-country transfers of all U.S. regulated products, software and technology to the designated Huawei entities. On August 17, 2020, the U.S. Department of Commerce published final regulations expanding the scope of the U.S. EAR to include additional products that would become subject to export restrictions relating to Huawei entities including HiSilicon. These new regulations restrict the sale to Huawei and the designated Huawei entities of certain non-U.S. made items, such as semiconductor devices, manufactured for or sold to Huawei entities including HiSilicon under specific, detailed conditions set forth in the new regulations. These new regulations have impacted our sales to Huawei, HiSilicon and their suppliers. We are taking appropriate actions, including filing license applications and obtaining licenses from the U.S. Department of Commerce. However, we do not expect these actions will mitigate the impact of the regulations on our sales to Huawei, HiSilicon and other suppliers. As a result, the regulations will continue to have an adverse impact on our business and financial results. It is uncertain the extent these new regulations and any additional regulations that may be implemented by the U.S. Department of Commerce or other government agency may have on our business with other customers or potential customers. Also, our controls related to Entity List compliance could be circumvented, exposing us to legal liabilities.

On April 28, 2020, the U.S. Department of Commerce published new export control regulations for certain U.S. products and technology sold to military end users or for military end-use in China, Russia and Venezuela. The definition of military end user is broad. The regulations went into effect on June 29, 2020. In December 2020, the U.S. Department of Commerce issued a list of companies in China and other countries that it considered to be military end users. Compliance with the new export controls has impacted our ability to sell products to certain customers in China. In addition, while we maintain an export compliance program, our compliance controls could be circumvented, exposing us to legal liabilities. We will continue to assess the impact of these export controls on our business and operations and take appropriate actions, including filing for licenses with the U.S. Department of Commerce, to minimize any disruption. However, we cannot be certain that the actions we take will mitigate all the risks associated with the export controls that may impact our business.

On October 7, 2022, the U.S. Department of Commerce published regulations restricting the export to China of advanced semiconductors, supercomputer technology, equipment for the manufacturing of advanced semiconductors and components and technology for the manufacturing in China of certain semiconductor manufacturing equipment. The restrictions impacted our sales to certain companies in China and our manufacturing and development operations in China. We mitigated the impact of these restrictions on our business by obtaining licenses from the U.S. Department of Commerce. On October 17, 2023, the U.S. Department of Commerce released new rules updating the export controls issued on October 7, 2022. The new rules, which take effect on November 17, 2023, significantly limit the impact of the October 7, 2022 restrictions on our business. However, the regulations may continue to have an adverse impact on certain actual or potential customers and on the global semiconductor industry. To the extent the regulations impact actual and potential customers or disrupt the global semiconductor industry, our business and revenues will be adversely impacted.

In response to the regulations issued by the U.S. Department of Commerce, the Chinese government has passed new laws, including blocking legislation, which may impact our business activities in China. The Company is assessing the potential impact of these new Chinese laws and monitoring relevant laws and regulations issued by the Chinese government. The impact of these new Chinese laws on our business activities in China remains uncertain at this time.

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

In January 2023, Teradyne’s Board of Directors cancelled our 2021 repurchase program and approved a new repurchase program for up to $2.0 billion of common stock. During the nine months ended October 1, 2023, we repurchased 3.4 million shares of common stock for a total cost of $349.3 million at an average price of $103.89 per share. We record share repurchases at cost, which includes broker commissions and related excise taxes. During the nine months ended October 2, 2022, we repurchased 7.2 million shares of common stock for $750.0 million at an average price of $103.83 per share.

The following table includes information with respect to repurchases we made of our common stock during the three months ended October 1, 2023, (in thousands except per share price):

Period |  | Total Number of Shares (or Units) Purchased |  |  |  | Average Price Paid per Share (or Unit) |  |  |  | Total Number of Shares (or Units) Purchased as Part of Publicly Announced Plans or Programs |  |  | Maximum Number (or Approximate Dollar Value) of Shares (or Units) that may Yet Be Purchased Under the Plans or Programs (2) |
July 3, 2023 - July 30, 2023 |  |  | 368 |  |  |  | $ | 112.14 |  |  |  |  | 368 |  |  | $ | 1,729,226,250 |
July 31, 2023 – August 27, 2023 |  |  | 335 |  |  |  | $ | 106.17 |  |  |  |  | 334 |  |  | $ | 1,693,807,449 |
August 28, 2023 – October 1, 2023 |  |  | 419 |  |  |  | $ | 103.14 |  |  |  |  | 418 |  |  | $ | 1,650,708,568 |
|  |  | 1,122 |  | (1) |  | $ | 107.00 |  | (1) |  |  | 1,119 |  |  |  |

(1)
Includes approximately three thousand shares at an average price of $109.16 withheld from employees for the payment of taxes.
(2)
As of January 1, 2023, share repurchases net of share issuances are subject to a 1% excise tax under the Inflation Reduction Act. Excise tax incurred is included as part of the cost basis of shares repurchased in the Condensed Consolidated Statements of Convertible Common Shares and Stockholders’ Equity.

We satisfy U.S. federal and state minimum withholding tax obligations due upon the vesting and the conversion of restricted stock units into shares of our common stock, by automatically withholding from the shares being issued, a number of shares with an aggregate fair market value on the date of such vesting and conversion that would satisfy the minimum withholding amount due.
