false P60Y 2017-06-15 0000097210 Q1--12-31 Includes $3.1 million and $1.8 million in 2021 and 2020, respectively, for leases of Teradyne’s systems recognized outside Accounting Standards Codification (“ASC”) 606 “Revenue from Contracts with Customers.”The carrying value represents the bifurcated debt component only, while the fair value is based on quoted market prices for the convertible note, which includes the equity conversion features. The amortization of prior service credit is included in the computation of net periodic postretirement benefit cost. See Note P: “Retirement Plans.”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 of $31.55, multiplied by 13.8 million shares. 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. Convertible notes hedge warrant shares were calculated using the difference between the average Teradyne stock price for the period and the warrant price of $39.59, multiplied by 13.8 million 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. Included in income (loss) before taxes are charges and credits related to restructuring and other, loss on convertible debt conversions and inventory charges. Included in Corporate and Other are: contingent consideration adjustments, loss on convertible debt conversions, interest income, interest expense, net foreign exchange gains (losses), pension, intercompany eliminations and acquisition related charges, legal fees and compensation. Total assets are attributable to each segment. Corporate assets consist of cash and cash equivalents, marketable securities and certain other assets. In the three months ended April 4, 2021, the fair value of contingent consideration for the earn-outs in connection with the acquisition of AutoGuide was reduced to zero, which resulted in a benefit of $7.2 million, primarily due to a decrease in forecasted revenues and earnings before interest and taxes. As of April 4, 2021, the maximum amount of contingent consideration that could be paid in connection with the acquisition of AutoGuide is $100.2 million. The remaining earn-out periods end on December 31, 2021 and December 31, 2022. The sellers of AutoGuide have filed an arbitration claim against Teradyne related to the earn-out alleging non-compliance with the earn-out provisions of the AutoGuide acquisition agreement. Teradyne disputes the allegations of non-compliance. The ultimate amount of contingent consideration for the earn-outs in connection with the acquisition of AutoGuide may be affected by the outcome of the dispute. In the three months ended March 29, 2020, the fair value of contingent consideration for the earn-outs in connection with the acquisitions of Mobile Industrial Robots Aps (“MiR”) and AutoGuide decreased by $2.9 million and $7.1 million, respectively, due to lower forecasts. In the three months ended March 29, 2020, Teradyne paid $8.9 million of contingent consideration for the earn-out in connection with the acquisition of MiR. 0000097210 2021-01-01 2021-04-04 0000097210

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 were reclassified to conform to the current year presentation. The December 31, 2020 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, 2021, for the year ended December 31, 2020.
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. Due to the
COVID-19
pandemic, there has been uncertainty and disruption in the global economy and our markets. 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 May 7, 2021, 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
In August 2020, the FASB issued ASU
2020-06
– “Debt—Debt with Conversion and Other Options and Derivatives and Hedging - Contracts in Entity’s Own Equity,” which simplifies the accounting for convertible debt instruments by reducing the number of accounting models and the number of embedded conversion features that could be recognized separately from the primary contract. This ASU requires a convertible debt instrument to be accounted for as a single liability measured at its amortized cost, as long as no other features require bifurcation and recognition as derivatives. This ASU requires an entity to use the
if-converted
method in the diluted earnings per share calculation for convertible instruments. This ASU will be effective for Teradyne on January 1, 2022. This ASU permits the use of either the modified retrospective or fully retrospective method of transition. Teradyne is evaluating the effects of the adoption of this ASU on its financial statements.

(a) | In the three months ended April 4, 2021, the fair value of contingent consideration for the earn-outs in connection with the acquisition of AutoGuide was reduced to zero, which resulted in a benefit of $7.2 million, primarily due to a decrease in forecasted revenues and earnings before interest and taxes. As of April 4, 2021, the maximum amount of contingent consideration that could be paid in connection with the acquisition of AutoGuide is $100.2 million. The remaining earn-out periods end on December 31, 2021 and December 31, 2022. The sellers of AutoGuide have filed an arbitration claim against Teradyne related to the earn-out alleging non-compliance with the earn-out provisions of the AutoGuide acquisition agreement. Teradyne disputes the allegations of non-compliance. The ultimate amount of contingent consideration for the earn-outs in connection with the acquisition of AutoGuide may be affected by the outcome of the dispute.

(b) | In the three months ended March 29, 2020, the fair value of contingent consideration for the earn-outs in connection with the acquisitions of Mobile Industrial Robots Aps (“MiR”) and AutoGuide decreased by $2.9 million and $7.1 million, respectively, due to lower forecasts.

(c) | In the three months ended March 29, 2020, Teradyne paid $8.9 million of contingent consideration for the earn-out in connection with the acquisition of MiR.

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 monetary assets and liabilities denominated in foreign currencies.
The notional amount of foreign currency forward contracts at April 4, 2021 and December 31, 2020 was $156.8 million and $152.9 million, respectively.
Gains and losses on foreign currency forward contracts and foreign currency remeasurement gains and losses on monetary assets and liabilities are included in other (income) expense, net.

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 from December 12, 2016 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
13

Table of Contents
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 conversion obligation by paying or delivering cash, shares of its common stock or a combination of cash and shares of its common stock, at Teradyne’s election. As of April 4, 2021, the conversion price was approximately $31.55 per share of Teradyne’s common stock. The conversion rate is subject to adjustment under certain circumstances. As of May 7, 2021,
thirty-six
holders had exercised the option to convert $66.9 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 $31.55. The Note Hedge Transactions cover, subject to customary anti-dilution adjustments, approximately 13.0 million shares of Teradyne’s common stock.
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. The Warrant Transactions currently cover, subject to customary anti-dilution adjustments, approximately 13.0 million shares of common stock. As of April 4, 2021, the strike price of the warrants was approximately $39.59 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.
Teradyne considered the guidance of ASC
815-40,
“Derivatives and Hedging—Contracts in Entity’s Own Equity,”
and concluded that the convertible note hedge is both indexed to Teradyne’s common stock and should be classified in stockholders’ equity in its statements of financial position. The convertible note hedge is considered indexed to Teradyne’s common stock as the terms of the Note Hedge Transactions do not contain an exercise contingency and the settlement amount equals the difference between the fair value of a fixed number of Teradyne’s shares and a fixed strike price. Because the only variable that can affect the settlement amount is Teradyne’s stock price, which is an input to the fair value of a
fixed-for-fixed
option contract, the convertible note hedge is considered indexed to Teradyne’s common stock.
Teradyne assessed whether the convertible note hedge should be classified as equity under ASC
815-40.
In the Note Hedge Transactions contract the settlement terms permit net cash settlement or net share settlement, at the option of Teradyne. Therefore, the criteria as set forth in ASC
815-40
were evaluated by Teradyne. In reviewing the criteria, Teradyne noted the following: (1) the convertible note hedge does not require Teradyne to issue shares; (2) there is no requirement to net cash settle the convertible note hedge for failure to make timely filings with the SEC; (3) in the case of termination, the convertible note hedge is settled in the same consideration as the holders of the underlying stock; (4) the counterparty does not have rights that rank higher than those of a shareholder of the stock underlying the convertible note hedge; and (5) there is no requirement to post collateral. Based on its analysis of those criteria, Teradyne concluded that the convertible note hedge should be recorded in equity and no further adjustment should be made in future periods to adjust the value of the convertible note hedge.
Teradyne analyzed the Warrant Transactions under ASC
815-40,
“Derivatives and Hedging—Contracts in Entity’s Own Equity,”
and other relevant literature, and determined that it met the criteria for classification as an equity transaction and is considered indexed to Teradyne’s common stock. As a result, Teradyne recorded the proceeds from the warrants as an increase to additional
paid-in
capital. Teradyne does not recognize subsequent changes in fair value of the warrants in its financial statements.

Table of Contents
The provisions of ASC
470-20,
“
Debt with Conversion and Other Options,
” are applicable to the Notes. ASC
470-20
requires Teradyne to separately account for the liability (debt) and equity (conversion feature) components of the Notes in a manner that reflects Teradyne’s nonconvertible debt borrowing rate at the date of issuance when interest cost is recognized in subsequent periods. Teradyne allocated $100.8 million of the $460.0 million principal amount of the Notes to the equity component, which represents a discount to the debt and will be amortized to interest expense using the effective interest method through December 2023. Accordingly, Teradyne’s effective annual interest rate on the Notes will be approximately 5.0%. The Notes are classified as long-term debt in the balance sheet based on their December 15, 2023 maturity date, except for the conversions that will occur in the second quarter of 2021, which
are
included in current debt. Debt issuance costs of approximately $7.2 million are being amortized to interest expense using the effective interest method over the seven-year term of the Notes. As of April 4, 2021, debt issuance costs were approximately $2.7 million.

As of April 4, 2021, the remaining unamortized discount was $40.8 million, which will be amortized over 2.7 years using the effective interest rate method. The carrying amount of the equity component was $100.8 million.
As of April 4, 2021, the conversion price was approximately $31.55 per share and the
if-converted
value of the notes was $1,668.6 million.
During the three months ended April 4, 2021, certain debt holders elected to convert $51.3
million of debt principal. The conversion of the debt was settled in cash for principal amount and in shares for the excess of conversion value over principal amount. The
1.2
million shares issued to the debt holders were received from exercising the convertible notes hedge call options.
Additional conversions of approximately
$15.6
m
illion of debt principal will occur in the second quarter of 2021. The liability component is included in current debt and the equity component is included in convertible common shares.
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 provides for a three-year, senior secured revolving credit facility of $400.0 million (the “Credit Facility”). The Credit Agreement further provides that, subject to customary conditions, Teradyne may seek to obtain from existing or new lenders incremental commitments under the Credit Facility in an aggregate principal amount not to exceed $150.0 million.
Proceeds from the Credit Facility may be used for general corporate purposes and working capital. Teradyne incurred $3.5 million in costs related to the revolving credit facility. These costs are being amortized over the three-year term of the revolving credit facility and are included in interest expense in the statement of operations. As of May 7, 2021, Teradyne has not borrowed any funds under the Credit Facility.

Table of Contents
The interest rates applicable to loans under the Credit Facility are, at Teradyne’s option, equal to either a base rate plus a margin ranging from 0.50% to 1.25% per annum or LIBOR, a minimum of 0.75%, plus a margin ranging from 1.50% to 2.25% 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 0.25% to 0.40% 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 LIBOR 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 May 7, 2021, Teradyne was in compliance with all covenants.

K. STOCK-BASED COMPENSATION
Under Teradyne’s stock compensation plans, Teradyne grants service-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 service-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. 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.

Table of Contents
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 three months ended April 4, 2021 and March 29, 2020, Teradyne granted 0.3 million and 0.4 million of service-based restricted stock unit awards to employees at a weighted average grant date fair value of $112.55 and $70.98, respectively.
During the three months ended April 4, 2021 and March 29, 2020, Teradyne granted 0.1 million of PBIT PRSUs with a grant date fair value of $112.28 and $70.94, respectively.
During the three months ended April 4, 2021 and March 29, 2020, Teradyne granted 0.1 million of TSR PRSUs, with a grant date fair value of $125.02 and $89.93, respectively. The fair value was estimated using the Monte Carlo simulation model with the following assumptions:

|  | For the Three Months Ended |
|  | April 4, |  |  | March 29, |
|  | 2021 |  |  | 2020 |
Risk-free interest rate |  |  | 0.2 | % |  |  | 1.5 | %
Teradyne volatility-historical |  |  | 43.9 | % |  |  | 34.9 | %
NYSE Composite Index volatility-historical |  |  | 22.9 | % |  |  | 11.4 | %
Dividend yield |  |  | 0.4 | % |  |  | 0.6 | %

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 $0.40 per share divided by Teradyne’s stock price on the grant date of $113.48 for the 2021 grant and an estimated annual dividend amount of $0.40 per share divided by Teradyne’s stock price on the grant date of $72.10 for the 2020 grant.
During the three months ended April 4, 2021 and March 29, 2020, Teradyne granted 0.1 million of service-based stock options to executive officers at a weighted average grant date fair value of $36.60 and $20.67, respectively.
The fair value of stock options was estimated using the Black-Scholes option-pricing model with the following assumptions:

|  | For the Three Months Ended |
|  | April 4, |  |  | March 29, |
|  | 2021 |  |  | 2020 |
Expected life (years) |  |  | 5.0 |  |  |  | 5.0 |
Risk-free interest rate |  |  | 0.4 | % |  |  | 1.6 | %
Volatility-historical |  |  | 37.8 | % |  |  | 31.6 | %
Dividend yield |  |  | 0.4 | % |  |  | 0.6 | %

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 $0.40 per share divided by Teradyne’s stock price on the grant date of $113.48 for the 2021 grant and an estimated annual dividend amount of $0.40 per share divided by Teradyne’s stock price on the grant date of $72.10 for the 2020 grant.

N. NET INCOME PER COMMON SHARE
The following table sets forth the computation of basic and diluted net income per common share:

Net income per common share-basic |  | $ | 1.23 |  |  | $ | 1.06 |
Net income per common share-diluted |  | $ | 1.09 |  |  | $ | 0.97 |

(1) | 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 of $31.55, multiplied by 13.8 million shares. 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 notes hedge warrant shares were calculated using the difference between the average Teradyne stock price for the period and the warrant price of $39.59, multiplied by 13.8 million 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.

The computation of diluted net income per common share for the three months ended March 29, 2020 excludes the effect of the potential vesting of 0.3 million restricted stock units because the effect would have been anti-dilutive.
O. RESTRUCTURING AND OTHER
During the three months ended April 4, 2021, Teradyne recorded a gain of $7.2 million for the decrease in the fair value of the AutoGuide contingent consideration liability, a gain of $0.2 million for the decrease in acquisition related compensation liability, partially offset by $0.2 million of severance charges primarily in Industrial Automation.
During the three months ended March 29, 2020, Teradyne recorded a gain of $10.0 million for the decrease in the fair value of the AutoGuide and MiR contingent consideration liabilities, partially offset by $1.4 million of acquisition related compensation and expenses and $0.7 million of severance charges related to headcount reductions primarily in Industrial Automation and Semiconductor Test.
P. RETIREMENT PLANS
ASC 715,
“Compensation—Retirement Benefits”
requires an employer with a defined benefit plan or other postretirement benefit plan to recognize an asset or a liability on its balance sheet for the overfunded or underfunded status of the plan. 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 of its plans.
Defined Benefit Pension Plans
Teradyne has defined benefit pension plans covering a portion of domestic employees and employees of certain
non-U.S.
subsidiaries. Benefits under these plans are based on employees’ years of service and compensation. Teradyne’s funding policy is to make contributions to these plans in accordance with local laws and to the extent that such contributions are tax deductible. The assets of the U.S. qualified pension plan consist primarily of fixed income and equity securities. In addition, Teradyne has unfunded qualified foreign plans as well as 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”).

Table of Contents
In the three months ended April 4, 2021, Teradyne contributed $0.8 million to the U.S. supplemental executive defined benefit pension plan and $0.3 million to certain qualified pension plans for
non-U.S.
subsidiaries.
For the three months ended April 4, 2021 and March 29, 2020, Teradyne’s net periodic pension cost was comprised of the following:

Total net periodic pension cost |  | $ | 617 |  |  | $ | 314 |  |  | $ | 722 |  |  | $ | 301 |

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.
For the three months ended April 4, 2021 and March 29, 2020, Teradyne’s net periodic postretirement benefit cost was comprised of the following:

|  | For the Three Months Ended |
|  | April 4, 2021 |  |  | March 29, 2020 |
|  | (in thousands) |
Service cost |  | $ | 16 |  |  | $ | 11 |

Total net periodic postretirement benefit cost |  | $ | 58 |  |  | $ | 71 |

Q. COMMITMENTS AND CONTINGENCIES
Purchase Commitments
As of April 4, 2021, Teradyne had entered into purchase commitments for certain components and materials. The purchase commitments covered by the agreements aggregate to approximately $680.7 million, of which $666.8 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 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 seeks full acceleration of the maximum earnout amount payable under the Purchase Agreement, or $106,875,000, for the alleged breach of the earnout provisions of the Purchase Agreement. On March 26, 2021, Teradyne and AutoGuide filed an answer denying that Teradyne and AutoGuide breached any provisions of the Purchase Agreement. A preliminary hearing will be scheduled once the arbitration tribunal is convened. While it is not possible at this stage to predict the outcome of the arbitration, Teradyne and AutoGuide intend to vigorously defend against the Industrial Automation LLC claims.

R. INCOME TAXES
A reconciliation of the United States federal statutory corporate tax rate to Teradyne’s effective tax rate was as follows:

|  | For the Three Months Ended |
|  | April 4, 2021 |  |  | March 29, 2020 |
US statutory federal tax rate |  |  | 21.0 | % |  |  | 21.0 | %
Foreign taxes |  |  | (4.7 | ) |  |  | (5.7 | )
International provisions of the U.S. Tax Cuts and Jobs Act of 2017 |  |  | (1.5 | ) |  |  | (0.2 | )
Tax credits |  |  | (1.3 | ) |  |  | (1.9 | )
Discrete benefit related to equity compensation |  |  | (6.2 | ) |  |  | (4.1 | )
Other, net |  |  | 1.0 |  |  |  | 1.5 |
Effective tax rate |  |  | 8.3 | % |  |  | 10.6 | %

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 April 4, 2021, 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 April 4, 2021 and December 31, 2020, Teradyne had $16.4 million and $17.9 million, respectively, of reserves for uncertain tax positions. The $1.5 million net decrease in reserves for uncertain tax positions is primarily related to U.S. state research and development credits generated in prior years, as well as U.S. federal research and development credits generated in the current year.
As of April 4, 2021, Teradyne estimates that it is reasonably possible that the balance of unrecognized tax benefits may decrease approximately $1.6 million in the next twelve months because of a lapse of statutes of limitation. The estimated decrease relates to loss carryforwards, research credits and U.S. manufacturing activities deductions.
Teradyne recognizes interest and penalties related to income tax matters in income tax expense. As of April 4, 2021 and December 31, 2020, $1.3 million and $1.2 million, respectively, of interest and penalties were accrued for uncertain tax positions. For the three months ended April 4, 2021 and March 29, 2020, expense of $0.1 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 three months ended April 4, 2021 was $6.2 million, or $0.03 per diluted share. The tax savings due to the tax holiday for the three months ended March 29, 2020 was $7.1 million, or $0.04 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.
S. SEGMENT INFORMATION
Teradyne has four reportable segments (Semiconductor Test, System Test, Industrial Automation and Wireless Test). Each of the reportable segments is also 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 Industrial Automation segment includes operations related to the design, manufacturing and marketing of collaborative robotic arms, autonomous mobile robots and advanced robotic control software. The Wireless Test segment includes operations related to the design, manufacturing and marketing of wireless test products and services. Each operating segment has a segment manager who is directly accountable to and maintains regular contact with Teradyne’s chief operating decision maker (Teradyne’s chief executive officer) to discuss operating activities, financial results, forecasts, and plans for the segment.
Teradyne evaluates performance based on several factors, of which the primary financial measure is business segment income (loss) before income taxes. The accounting policies of the business segments in effect are described in Note B: “Accounting Policies” in Teradyne’s Annual Report on Form
10-K
for the year ended December 31, 2020.

for the year ended December 31, 2020. 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 automation equipment for test and industrial applications. We design, develop, manufacture and sell automatic test systems 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 industrial automation products include collaborative robotic arms, autonomous mobile robots (“AMRs”) and advanced robotic control software used by global manufacturing, logistics and light industrial customers to improve quality, increase manufacturing and material handling efficiency and decrease manufacturing and logistics costs. Our automatic test equipment and industrial automation 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

| • |  | industrial automation (“Industrial Automation”) 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.
We have grown our Industrial Automation business through acquisitions, including Mobile Industrial Robots A/S (“MiR”), a leading maker of AMRs for industrial applications, in 2018 and AutoGuide, LLC (“AutoGuide”), a maker of high payload AMRs, in 2019. The market for our industrial automation 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 Q1 2021, revenue in our test businesses exceeded our plan as a result of Semiconductor Test demand in several market segments and continued strength in our System Test businesses. In Q1 2021, our Industrial Automation recovered from the impact of the global industry downturn and the
COVID-19
pandemic in 2020 and revenue was above our plan. In 2021, we expect strong momentum in our test businesses and return to growth of our Industrial Automation businesses.
Our strategy is to focus on profitably growing market share in our test businesses, the introduction of differentiated products that target growth segments, and accelerating growth through continued investment in our Industrial Automation businesses. We plan to execute on our strategy while balancing capital allocations between returning capital to our shareholders through dividends and stock repurchases and using capital for opportunistic acquisitions.
Impact of the
COVID-19
Pandemic on our Business
The novel coronavirus
(COVID-19)
pandemic has resulted in government authorities implementing numerous measures in an effort to contain the spread of the virus, such as travel bans and restrictions, limitations on gatherings or social distancing requirements, quarantines,
shelter-in-place
orders, and business limitations and shutdowns. These measures have impacted our
day-to-day
operations and disrupted our business, workforce and operations, as well as the operations of our customers, contract manufacturers and suppliers. We are continuing to monitor the rapidly evolving situation regarding the
COVID-19
pandemic and the availability and impact of vaccinations. However, we are unable to accurately predict the full impact of
COVID-19,
which will depend on future developments that are highly uncertain and cannot be predicted with accuracy, including, but not limited to, any new surges in areas where we do business, the availability of vaccinations, any further government actions to contain the virus or treat its impact, and how quickly and to what extent normal economic and operating conditions can resume.

Health and Safety
In response to the
COVID-19
pandemic, we have taken proactive, aggressive action to protect the health and safety of our employees, customers, contract manufacturers and suppliers and we have complied with all government orders around the globe. The spread of
COVID-19
has caused us to modify our business practices, including implementing social distancing protocols, suspending employee travel, requiring most employees to work remotely, cancelling physical participation in meetings, and extensively and frequently disinfecting our workspaces. Around the world, the majority of our employees are working from home. However, some of our engineering, operations, supply line and customer support teams must be
on-site
at our or our customers’ facilities. We are providing those
on-site
employees with the necessary protective resources and procedures to minimize their exposure risk. We may take further actions as may be required or recommended by government authorities or that we determine are in the best interests of our employees, customers, contract manufacturers and suppliers.
Operations
We believe the
COVID-19
pandemic, and the numerous measures implemented by authorities in response, has adversely impacted our results of operations, including by increasing costs, but we cannot accurately estimate the amount of the impact to our first quarter of 2021 financial results or to our future financial results. In addition, the pandemic has disrupted our contract manufacturers and suppliers, and has resulted in some instances in short-term cost increases to meet customer demand. While the duration and severity of the pandemic may further impact our workforce and operations, as well as those of our customers, contract manufacturers and suppliers, we expect that our manufacturing facilities will remain operational, at sufficient capacity to support production demand. We are monitoring our operations closely in an effort to avoid any potential productivity loss caused by responses to the
COVID-19
pandemic.
Supply
We have not experienced any significant impacts or interruptions to our supply chain as a result of the
COVID-19
pandemic. However, our suppliers have faced and may continue to face difficulties maintaining operations in light of government-ordered restrictions, including social distancing requirements and
shelter-in-place
mandates. Our supply chain team, and our suppliers, overcame numerous supply, production, and logistics obstacles in 2020, but there is no assurance we or they will be able to do so in the future. Although we regularly monitor the financial health of companies in our supply chain, financial hardship on our suppliers or
sub-suppliers
caused by the
COVID-19
pandemic could disrupt our ability to obtain components required to manufacture our products, adversely affecting our operations and in some instances result in higher costs and delays, both for obtaining components and shipping finished goods to customers, which could harm our profitability, make our products less competitive, or cause our customers to seek alternative suppliers.
Demand
The
COVID-19
pandemic has significantly increased economic uncertainty in our markets. Demand for our Test products was strong throughout 2020 and in the first quarter of 2021. Our Industrial Automation business, however, experienced a significant decline in demand through the first half of 2020 due to
COVID-19
related shutdowns affecting global manufacturing but demand recovered in the second half of 2020 from the low point in the second quarter and continued to recover in the first quarter of 2021. The
COVID-19
pandemic could cause further global economic disruption that could cause demand for our products to decline, which would adversely affect our business.
Liquidity
Although there is continued uncertainty related to the impact of the
COVID-19
pandemic on our future results, we believe our business model and our current cash reserves leave us well-positioned to manage our business through this crisis. We have a strong balance sheet as well as an operating model that we believe is capable of flexing up and down with extreme demand swings while still remaining profitable. Based on our analysis, we believe our existing balances of cash and cash equivalents and our currently anticipated operating cash flows will be sufficient to meet our working capital needs and other capital and liquidity requirements for the next twelve months. However, due to the uncertainty related to the future impact of the
COVID-19
pandemic, in order to bolster our liquidity position, on May 1, 2020 we entered into a credit agreement providing for a three-year, senior secured revolving credit facility of $400 million as further described in Note G: “Debt.” As of May 7, 2021, we have not borrowed any funds under the credit facility.
We are continuing to monitor the evolving situation regarding the
COVID-19
pandemic, the availability of vaccinations where we do business and guidance from government authorities around the world. In these circumstances, there may be developments outside our control requiring us to adjust our operating plan. As a result, given the uncertain nature of this situation, we are not able to accurately predict the full extent of the impact of
COVID-19
on our business, financial condition, results of operations, liquidity, or cash flows in the future. In addition, see Part II—Item 1A, “Risk Factors,” included in our Annual Report on Form
10-K
for the fiscal year ended December 31, 2020 for our risk factors regarding risks associated with the
COVID-19
pandemic.

Results of Operations
First Quarter 2021 Compared to First Quarter 2020
Revenues
Revenues by our reportable segments were as follows:

|  | For the Three Months Ended |  |  |  |
|  | April 4, 2021 |  |  | March 29, 2020 |  |  | Dollar Change |
|  | (in millions) |

Interest income decreased by $1.9 million primarily due to lower interest rates in 2021 compared to 2020. Other (income) expense, net decreased by $3.0 million primarily due to changes in unrealized gains/losses on equity securities, from losses in 2020 to gains in 2021, and a loss on convertible debt conversions in 2021.

The increase in income before income taxes in Semiconductor Test was driven primarily by a rise in tester sales driven by high performance compute processor, automotive and industrial applications and incremental memory test sales of flash and DRAM memory testers. The improvement in income before income taxes in System Test was primarily due to elevated sales in Storage Test of system level and hard disk drive testers, and greater sales in Production Board Test due to higher automotive electronics demand, partially offset by lower sales in Defense/Aerospace. The decrease in income before taxes in Wireless Test was primarily due to lower revenue due to lesser demand for cellular test products, partially offset by higher sales in connectivity test products. The decrease in loss before income taxes in Industrial Automation was driven primarily by demand for collaborative robotic arms and MiR’s autonomous mobile robots and lower intangible assets amortization.
Income Taxes
The effective tax rate for the three months ended April 4, 2021 and March 29, 2020 was 8.3% and 10.6%, respectively. The decrease in the effective tax rate from the three months ended March 29, 2020 to the three months ended April 4, 2021 was primarily attributable to increases in benefit from equity compensation and the international provisions of the U.S. Tax Cuts and Jobs Act of 2017, 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.
Contractual Obligations
There have been no changes outside of ordinary course of business to our contractual obligations as disclosed in our Annual Report on Form
10-K
for the year ended December 31, 2020.
Liquidity and Capital Resources
Our cash, cash equivalents, and marketable securities balances decreased by $129.3 million in the three months ended April 4, 2021 to $1,425.1 million.
Operating activities during the three months ended April 4, 2021 provided cash of $38.1 million. Changes in operating assets and liabilities used cash of $209.1 million. This was due to a $209.5 million increase in operating assets and a $0.4 million increase in operating liabilities.
31

Table of Contents
The increase in operating assets was due to an $87.5 million greater accounts receivable due to improved sales, an $86.1 million increase in prepayments and other assets due to prepayments to our contract manufacturers as a result of higher forecasted revenues, and a $35.9 million rise in inventories.
The change in operating liabilities was due to a $44.5 million rise in accounts payable, a $26.4 million increase in other accrued liabilities, an $8.0 million growth in deferred revenue and customer advance payments, and a $4.9 million increase in income taxes, partially offset by an $81.5 million decrease in accrued employee compensation and $1.9 million of retirement plan contributions.
Investing activities during the three months ended April 4, 2021 provided cash of $4.7 million due to $194.2 million and $61.3 million in proceeds from maturities and sales of marketable securities, partially offset by $211.6 million used for purchases of marketable securities, and $39.3 million used for purchases of property, plant and equipment.
Financing activities during the three months ended April 4, 2021 used cash of $126.7 million, due to $51.3 million used for payments of convertible debt principal, $45.2 million used for the repurchase of 0.4 million shares of common stock at an average price of $120.73 per share, $30.7 million used for payments related to net settlements of employee stock compensation awards, and $16.7 million used for dividend payments, partially offset by $17.1 million from the issuance of common stock under employee stock purchase and stock option plans.
Operating activities during the three months ended March 29, 2020 provided cash of $43.1 million. Changes in operating assets and liabilities used cash of $172.8 million. This was due to a $150.6 million increase in operating assets and a $22.2 million decrease in operating liabilities.
The increase in operating assets was primarily due to $126.8 million greater accounts receivable due to improved sales and a $39.6 million rise in prepayments and other assets, partially offset by a $15.8 million decrease in inventories.
The decrease in operating liabilities was due to a $44.4 million decrease in accrued employee compensation primarily due to first quarter payments related to variable compensation, $1.3 million of retirement plan contributions, $0.9 million lower deferred revenue and customer advance payments, partially offset by a $15.3 million increase in income taxes, a $7.1 million increase in other accrued liabilities, and a $2.0 million increase in accounts payable.
Investing activities during the three months ended March 29, 2020 used cash of $110.2 million, due to $187.1 million used for purchases of marketable securities, and $36.7 million used for purchases of property, plant and equipment, partially offset by $98.5 million and $15.0 million in proceeds from maturities and sales of marketable securities, respectively, and $0.1 million, net of cash acquired, for the acquisition of AutoGuide.
Financing activities during the three months ended March 29, 2020 used cash of $113.9 million, due to $79.0 million used for the repurchase of 1.3 million shares of common stock at an average price of $58.81 per share, $22.1 million used for payments related to net settlements of employee stock compensation awards, $16.7 million used for dividend payments, and $8.9 million used for a payment related to MiR acquisition contingent consideration, partially offset by $12.8 million from the issuance of common stock under employee stock purchase and stock option plans.
In January 2021 and 2020, our Board of Directors declared a quarterly cash dividend of $0.10 per share. Dividend payments for the three months ended April 4, 2021 and March 29, 2020 were $16.7 million and $16.7 million, respectively.
In January 2021, our Board of Directors cancelled the January 2020 repurchase program and approved a new repurchase program for up to $2.0 billion of common stock. Unless terminated by resolution of our Board of Directors, the repurchase program will expire when we have repurchased all shares authorized for repurchase under the share repurchase program. We intend to repurchase a minimum of $600 million in 2021.
During the three months ended April 4, 2021, we repurchased 0.4 million shares of common stock for $45.2 million at an average price of $120.73 per share. During the three months ended March 29, 2020, we repurchased 1.3 million shares of common stock for $79.0 million at an average price of $58.81 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 for a three-year, senior secured revolving credit facility of $400 million. As of May 7, 2021, we have not borrowed any funds under the credit facility.

Table of Contents
We believe our cash, cash equivalents and marketable securities balance 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. At this time, the
COVID-19
pandemic has not had an impact on our liquidity, but there is no assurance that continued impacts resulting from the pandemic will not have an adverse effect in the future.
Equity Compensation Plans
As discussed in Note Q: “Stock Based Compensation” in our 2020 Annual Report on Form
10-K,
we have a 1996 Employee Stock Purchase Plan and a 2006 Equity and Cash Compensation Incentive Plan (the “2006 Equity Plan”).
The purpose of the 1996 Employee Stock Purchase Plan is to encourage stock ownership by all eligible employees of Teradyne. The purpose of the 2006 Equity Plan is to provide equity ownership and compensation opportunities in Teradyne to our employees, officers, directors, consultants and/or advisors. Both plans were approved by our shareholders.
Recently Issued Accounting Pronouncements
In August 2020, the FASB issued ASU
2020-06
– “Debt—Debt with Conversion and Other Options and Derivatives and Hedging—Contracts in Entity’s Own Equity,” which simplifies the accounting for convertible debt instruments by reducing the number of accounting models and the number of embedded conversion features that could be recognized separately from the primary contract. This ASU requires a convertible debt instrument to be accounted for as a single liability measured at its amortized cost, as long as no other features require bifurcation and recognition as derivatives. This ASU requires an entity to use the
if-converted
method in the diluted earnings per share calculation for convertible instruments. This ASU will be effective for Teradyne on January 1, 2022. This ASU permits the use of either the modified retrospective or fully retrospective method of transition. We are evaluating the effects of the adoption of this ASU on our 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, 2021. 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, 2020.
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 April 4, 2021, the Notes had a fair value of $1,664.7 million. The table below provides a sensitivity analysis of hypothetical 10% changes of Teradyne’s stock price as of the end of the first quarter of 2021 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 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 convertible senior 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 note 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 |  | $ | 1,833,685 |  |  | $ | 169,018 |  |  |  | 10.2 | %

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
33

Table of Contents
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 April 4, 2021 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. We believe that we have meritorious defenses against all pending claims and intend 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, we believe the potential losses associated with all of these actions are unlikely to have a material adverse effect on our 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 seeks full acceleration of the maximum earnout amount payable under the Purchase Agreement, or $106,875,000, for the alleged breach of the earnout provisions of the Purchase Agreement. On March 26, 2021, Teradyne and AutoGuide filed an answer denying that Teradyne and AutoGuide breached any provisions of the Purchase Agreement. A preliminary hearing will be scheduled once the arbitration tribunal is convened. While it is not possible at this stage to predict the outcome of the arbitration, Teradyne and AutoGuide intend to vigorously defend against the Industrial Automation LLC claims.

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, 2020, 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 and many of these risks could be further increased due to the
COVID-19
pandemic.
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.
The global supply shortage of electrical components may impact our ability to meet customer demand.
There is currently a global supply shortage of electrical components, including semiconductor chips. As a result, we may experience increases in our lead times, costs to manufacture our products and may not be able to manufacture and deliver all of the orders placed by our customers. If we are unable to secure manufacturing capacities from our current suppliers and contract manufacturers, our ability to deliver our products to our customers may be negatively impacted. Also, our suppliers and contract manufacturers may increase their fees, which would result in an increase in our manufacturing costs, which we may not be fully able to pass to our customers, which could have a negative impact on our results of operations and financial condition. Additionally, if any of our suppliers and contract manufacturers were to cancel contracts or commitments or fail to meet the quality or delivery requirements needed to satisfy customer orders for our products, we could lose time-sensitive customer orders, have significantly decreased revenues and earnings and be subject to contractual penalties, which would have a material adverse effect on our business, results of operations and financial condition.

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

In January 2020, Teradyne’s Board of Directors authorized a new stock repurchase program for up to $1.0 billion of common stock.
