B.ACCOUNTING POLICIES The consolidated financial statements include the accounts of Teradyne and its wholly owned subsidiaries. All significant intercompany balances and transactions are eliminated. Certain prior years’ amounts were reclassified to conform to the current year presentation. Preparation of Financial Statements and Use of Estimates The preparation of consolidated financial statements requires management to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent liabilities. On an on-going basis, management evaluates its estimates, including those related to revenue, inventories, investments, goodwill, intangible and other long-lived assets, accounts receivable, income taxes, deferred tax assets and liabilities, pensions, warranties, 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 judgments 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 Annual Report on Form 10-K. 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. Revenue Recognition Revenue from Contracts with Customers In accordance with ASC 606, Teradyne recognizes revenues, when or as control is transferred to a customer. Teradyne’s determination of revenue is dependent upon a five-step process outlined below. •Teradyne accounts for a contract with a customer when there is written approval, the contract is committed, the rights of the parties, including payment terms, are identified, the contract has commercial substance and consideration is probable of collection. •Teradyne periodically enters into contracts with customers in which a customer may purchase a combination of goods and services, such as products with extended warranty obligations. Teradyne determines performance obligations by assessing whether the products or services are distinct from the other elements of the contract. In order to be distinct, the product or service must perform either on its own or with readily available resources and must be separate within the context of the contract. •Teradyne determines the transaction price to be the amount of consideration to which Teradyne expects to be entitled to, which is generally at contractually stated prices.•Transaction price is allocated to each individual performance obligation based on the standalone selling price of that performance obligation. Teradyne uses standalone transactions when available to value each performance obligation. If standalone transactions are not available, Teradyne will estimate the standalone selling price through market assessments or"

As previously disclosed, the restrictions impacted Teradyne’s sales to certain companies in China and Teradyne’s manufacturing and development operations in China. Teradyne mitigated the impact of these restrictions on its business by obtaining licenses from the Department of Commerce. On October 17, 2023, the Department of Commerce released new rules updating the exporting controls issued on October 7, 2022. The new rules which took effect on November 17, 2023 significantly limit the impact of the October 7, 2022 restrictions on Teradyne’s business. However, the regulations may continue to have an adverse impact on certain actual or potential customers of Teradyne and on the global semiconductor industry. To the extent the regulations impact actual and potential customers or disrupt the global semiconductor industry, Teradyne’s business and revenues will be adversely impacted.

As of December 31, 2022, the fair market value of investments with unrealized losses less than one year and greater than one year totaled $66.3 million and $33.4 million, respectively. 58 Table of Contents Teradyne reviews its investments to identify and evaluate investments that have an indication of possible impairment. Based on this review, Teradyne determined that the unrealized losses related to these investments at December 31, 2023 and 2022 were not other than temporary. The contractual maturities of investments in available-for-sale marketable securities held at December 31, 2023 were as follows: Cost Fair Value (in thousands) Due within one year $ 62,385 $ 62,154 Due after 1 year through 5 years 23,703 23,319 Due after 5 years through 10 years 6,049 5,735 Due after 10 years 39,159 32,475 Total $ 131,296 $ 123,683 Contractual maturities of investments in available-for-sale marketable securities held at December 31, 2023 exclude debt mutual funds with the fair market value of $8.8 million as they do not have a contractual maturity date. 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. 59 Table of Contents At December 31, 2023 and 2022, to hedge certain of its local currency balance sheet assets and liabilities, Teradyne had the following contracts to buy and sell non-U.S. currencies for U.S. dollars and other non-U.S. currencies with the following notional amounts: Net Notional Value December 31,2023 December 31, 2022 (in millions) Currency Hedged (Buy/Sell) U.S. dollar/Taiwan dollar $ 42.7 $ 29.2 U.S. dollar/Danish krone 36.0 — U.S. dollar/Japanese yen 11.0 37.1 U.S. dollar/Korean won 7.2 6.4 U.S. dollar/British pound sterling 1.5 1.2 Euro/U.S. dollar 25.3 38.4 Singapore dollar/U.S. dollar 16.6 33.5 Philippine peso/U.S. dollar 10.1 2.7 Chinese yuan/U.S. dollar 1.0 2.2 Danish krone/U.S. dollar 0.7 — Total 152.1 150.7 The change in the fair value of the outstanding contracts was a loss of $1.8 million and $0.9 million, respectively, at December 31, 2023 and 2022. Unrealized 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. At December 31, 2023 and 2022, Teradyne had the following cash flow hedge contracts to buy and sell non-U.S. currencies for U.S. dollars with the following notional amounts: Net Notional Value December 31,2023 December 31, 2022 (in millions) Currency Hedged (Buy/Sell) U.S. dollar/Japanese yen $ 35.5 $ 61.2 U.S. dollar/Taiwan dollar — 10.9 Japanese yen/U.S. dollar — 23.4 Taiwan dollar/U.S. dollar — 5.5 Total $ 35.5 $ 101.0 The change in the fair value of the outstanding cash flow hedge contracts was a gain of $0.6 million at December 31, 2023 and a loss of $3.2 million at December 31, 2022.Unrealized gains and losses on foreign currency cash flow hedge contracts are included in accumulated other comprehensive income (loss). At maturity, the gains or losses associated with cash flow hedge contracts are recorded to revenue. On November 7, 2023, in connection with our agreement to acquire 10% investment in Technoprobe S.p.A we purchased a call option to buy 481.0 million Euros. The expiration date of the option is April 26, 2024. At December 31, 2023, the fair value of the outstanding contract was $17.4 million and an unrealized gain of $7.5 million was recorded in other (income) expense, net.60 Table of Contents The following table summarizes the fair value of derivative instruments as of December 31, 2023 and 2022: Balance Sheet Location December 31,2023 December 31,2022 (in thousands) Derivatives not designated as hedging instruments: Foreign exchange forward contracts Other current assets $ 733 $ 86 Foreign exchange option contracts Other current assets 17,364 — Foreign exchange forward contracts Other current liabilities (2,545 ) (990 ) Derivatives designated as hedging instruments: Foreign exchange forward contracts Other current assets 648 — Foreign exchange option contracts Other current liabilities — (3,225 ) Total derivatives $ 16,200 $ (4,129 ) The following table summarizes the effect of derivative instruments in the statements of operations recognized for the years ended December 31, 2023, 2022, and 2021: Location of (Gains) Losses Recognized in Statementof Operations December 31,2023 December 31,2022 December 31,2021 (in thousands) Derivatives not designated as hedging instruments: Foreign exchange forward contracts (1) Other (income) expense, net $ (1,843 ) $ (2,482 ) $ 6,488 Foreign exchange option contracts Other (income) expense, net (7,464 ) — — Derivatives designated as hedging instruments: Foreign exchange forward and option contracts Revenue (3,127 ) (251 ) — Total derivatives $ (12,434 ) $ (2,733 ) $ 6,488 (1)The table does not reflect the corresponding gains and losses from the remeasurement of the monetary assets and liabilities denominated in foreign currencies. For the years ended December 31, 2023, 2022 and 2021, net losses (gains) from remeasurement of monetary assets and liabilities denominated in foreign currencies were $10.9 million, $10.8 million, and $(2.1) million, respectively. See Note J: “Debt” regarding derivatives related to the convertible senior notes. Concentration of Credit Risk Financial instruments which potentially subject Teradyne to concentrations of credit risk consist principally of cash equivalents, marketable securities, forward currency contracts and accounts receivable. Teradyne’s cash equivalents consist primarily of money market funds invested in U.S. Treasuries and government agencies. Teradyne’s fixed income available-for-sale marketable securities have a minimum rating of AA by one or more of the major credit rating agencies. Teradyne places foreign currency forward contracts with high credit-quality financial institutions in order to minimize credit risk exposure. Concentrations of credit risk with respect to accounts receivable are limited due to the large number of geographically dispersed customers. Teradyne performs ongoing credit evaluations of its customers’ financial condition and from time to time may require customers to provide a letter of credit from a bank to secure accounts receivable. As of December 31, 2023, one customer of our Semiconductor Test segment, Texas Instruments Inc., accounted for 18% of our accounts receivable balance. There were no customers who accounted for more than 10% of our accounts receivable balance as of December 31, 2022.

      "prior_body": "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. 59 59 Table of Contents Table of Contents Table of Contents At December 31, 2023 and 2022, to hedge certain of its local currency balance sheet assets and liabilities, Teradyne had the following contracts to buy and sell non-U.S. currencies for U.S. dollars and other non-U.S. currencies with the following notional amounts: Net Notional Value December 31,2023 December 31, 2022 (in millions) Currency Hedged (Buy/Sell) U.S. dollar/Taiwan dollar $ 42.7 $ 29.2 U.S. dollar/Danish krone 36.0 — U.S. dollar/Japanese yen 11.0 37.1 U.S. dollar/Korean won 7.2 6.4 U.S. dollar/British pound sterling 1.5 1.2 Euro/U.S. dollar 25.3 38.4 Singapore dollar/U.S. dollar 16.6 33.5 Philippine peso/U.S. dollar 10.1 2.7 Chinese yuan/U.S. dollar 1.0 2.2 Danish krone/U.S. dollar 0.7 — Total 152.1 150.7 At December 31, 2023 and 2022, to hedge certain of its local currency balance sheet assets and liabilities, Teradyne had the following contracts to buy and sell non-U.S. currencies for U.S. dollars and other non-U.S. currencies with the following notional amounts:"

      "current_body": "Our cash, cash equivalents and marketable securities balance decreased by $213.4 million in 2024 to $723.8 million. Cash decreased due to investments in businesses for $532.1 million, stock repurchases in the amount of $198.6 million, and quarterly cash dividend payments in the amount of $76.4 million, partially offset by proceeds from the sale of business and cash generated by our global operations. Operating activities during 2024 provided cash of $672.2 million. Changes in operating assets and liabilities used cash of $23.9 million. This was due to a $75.5 million decrease in operating assets and a $51.6 million decrease in operating liabilities. The decrease in operating assets was primarily due to a decrease in other assets and inventory of $119.5 million and $8.7 million respectively, partially offset by a $52.7 million increase in accounts receivable, driven by higher sales at year-end. The decrease in operating liabilities was due to a $48.2 million decrease in accounts payable, a $6.2 million decrease in other accrued compensation, $5.8 million of retirement plan contributions, and a $3.6 million decrease in income taxes, partially offset by a $12.2 million increase in deferred revenue and customer advance payments.

Operating activities during 2023 provided cash of $585.2 million. Changes in operating assets and liabilities used cash of $9.6 million. This was due to a $33.2 million decrease in operating assets and a $42.8 million decrease in operating liabilities. The decrease in operating assets was due to a $71.0 million decrease in accounts receivable due to lower sales and a $5.3 million decrease in inventories, partially offset by a $43.1 million increase in prepayments and other assets due to prepayments to our contract manufacturers. The decrease in operating liabilities was due to a $57.2 million decrease in deferred revenue and customer advance payments, a $26.9 million decrease in income taxes, a $21.2 million decrease in accrued employee compensation, and $5.5 million of retirement plan contributions, partially offset by a $45.0 million increase in accounts payable, and a $23.0 million increase in other accrued liabilities. Investing activities during 2023 used cash of $179.6 million, due to $161.9 million used for purchases of marketable securities, $159.6 million used for purchases of property, plant and equipment, and $5.0 million used for issuance of convertible loans, partially offset by $85.0 million and $61.4 million in proceeds from maturities and sales 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.

In January 2024, May 2024, August 2024 and November 2024, our Board of Directors declared a quarterly cash dividend of $0.12 per share. Total dividend payments in 2024 were $76.4 million. In January 2023, May 2023, August 2023 and November 2023, our Board of Directors declared a quarterly cash dividend of $0.11 per share. Total dividend payments in 2023 were $67.9 million. 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. In 2024, we repurchased 1.7 million shares of common stock for $198.6 million, which excludes related excise tax, at an average price of $114.63 per share. In 2023, we repurchased 3.9 million shares of common stock for $397.2 million, which excludes related excise tax, at an average price of $102.47 per share against the 2023 repurchase program. The cumulative repurchases as of December 31, 2024, under the 2023 repurchase program, were 5.6 million shares of common stock for $595.2 million, exclusive of tax, at an average price per share of $106.21. In 2025, we intend to repurchase up to $400.0 million. 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 27, 2024, we paid 483.1 million Euros, equivalent to $524.1 million, to purchase a combination of previously issued and outstanding shares and shares newly issued by Technoprobe, S.p.A. (\"Technoprobe\"). The shares purchased represent 10% of the issued and outstanding shares of Technoprobe. We also received a board seat as part of the purchase. Additionally, as part of the transaction, we completed the sale of the Device Interface Solutions (\"DIS\") business, a component of the Semiconductor Test segment, to Technoprobe for $85.0 million in cash, net of cash and cash equivalents sold, and a customary working capital adjustment. The sale resulted in a pre-tax gain of $57.1 million recorded as 'Gain on sale of business' in the consolidated statement of operations. 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. On November 7, 2023, the Credit Agreement was amended to allow for the purchase of the shares of Technoprobe. On May 16, 2024, we borrowed $185.0 million under the credit agreement to partially fund the acquisition of 10% of the issued and outstanding shares of Technoprobe. We fully repaid our borrowings on the revolving credit facility prior to December 31, 2024. As of February 20, 2025, there are no outstanding borrowings under the credit facility. We expect operations to continue to be the primary source of cash to operate the business and meet material cash commitments, including any payments of convertible debt principal, our stock repurchase program, our quarterly dividends, our office lease obligations, contractual obligations related to inventory purchases and the construction of new facilities. 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 December 31, 2024, our future contractual obligations were related to debt, leases, retirement plan liabilities, deferred tax benefits, and purchase obligations.

The information security organization manages and continually enhances a robust enterprise security structure with the goal of preventing cybersecurity incidents to the extent feasible, while simultaneously increasing system resilience and deploying highly proficient detection and response capabilities in an effort to minimize the business impact should an incident occur. Central to this organization is our global cyber operations team, which is responsible for the protection, detection, and response capabilities used in the defense of critical data and enterprise computing services. We also have a corporate-wide insider threat detection program to proactively identify external and internal threats and mitigate those threats in a timely manner. Our broader Teradyne employee community also has a key role in our cybersecurity defenses and is immersed in a comprehensive training and awareness curriculum to build and promote a corporate culture supportive of security.Third parties also play a role in our cybersecurity. We engage third-party services to provide 24x7x365 monitoring, escalation, and response to cyber events. In addition to consulting on best practices, we leverage third parties for independent evaluations of our security controls through penetration testing and independent audits. These evaluations include testing both the design and operational effectiveness of security controls. We also share and receive threat intelligence with our industry peers, cybersecurity associations, and our cyber controls vendors.We rely on contract manufacturing organizations and distributors to deliver our products to our customers, and a cybersecurity incident at one of these organizations or a key supplier could materially adversely impact us. We assess third party and supply chain cybersecurity controls through risk monitoring services tailored to align with our risk policy. Notwithstanding the extensive approach we take to cybersecurity, we may not be successful in preventing or mitigating a cybersecurity incident that could have a material adverse effect on us, either directly within our managed environment or indirectly via a third-party partner or supply chain vendor.

Teradyne depreciates the test systems manufactured internally over a six-year life to cost of revenues, engineering and development, and selling and administrative expenses. Teradyne often sells internally manufactured test equipment to customers. Upon the sale of an internally manufactured test system, the net book value of the system is transferred to inventory and expensed as cost of revenues. The net book value of internally manufactured test systems sold in the years ended December 31, 2024, 2023, and 2022 was $4.0 million, $2.8 million, and $6.6 million, respectively. Convertible Debt Teradyne adopted Accounting Standards Update (“ASU”) ASU 2020-06 – “Debt—Debt with Conversion and Other Options and Derivatives and Hedging—Contracts in Entity’s Own Equity,” on January 1, 2022 using the modified retrospective method of adoption. As a result of 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. In accordance with ASU 2020-06, Teradyne accounts for a convertible debt instrument as a single liability measured at its amortized cost, as long as no other features require bifurcation and recognition as derivatives. Unsettled shares are recorded in current debt, and there is no recognition of a debt discount, which was previously amortized to interest expense. Settled shares reduce the outstanding debt balance in an amount equal to the cash paid, but do not result in any gain or loss on extinguishment. We use the if-converted method in the diluted EPS calculation for convertible instruments. Leases Under ASC 842, a contract is or contains a lease when Teradyne has the right to control the use of an identified asset. Teradyne determines if an arrangement is a lease at inception of the contract, which is the date on which the terms of the contract are agreed to and the agreement creates enforceable rights and obligations. The commencement date of the lease is the date that the lessor makes an underlying asset available for use by Teradyne. As of December 31, 2024, Teradyne does not have material leases that have not yet commenced. Teradyne determines if the lease is an operating or finance lease at the lease commencement date based upon the terms of the lease and the nature of the asset. The lease term used to calculate the lease liability includes options to extend or terminate the lease when it is reasonably certain that the option will be exercised. The lease liability is measured at the present value of future lease payments, discounted using the discount rate for the lease at the commencement date. As Teradyne is typically unable to determine the implicit rate, Teradyne uses an incremental borrowing rate based on the lease term and economic environment at commencement date. Teradyne initially measures payments based on an index by using the applicable rate at lease commencement. Variable payments that do not depend on an index are not included in the lease liability and are recognized as they are incurred. The right-of-use (“ROU”) asset is initially measured as the amount of lease liability, adjusted for any initial lease costs, prepaid lease payments, and reduced by any lease incentives. Property, Plant and Equipment Property, plant and equipment are stated at cost and depreciated over the estimated useful lives of the assets. Leasehold improvements and major renewals are capitalized and included in property, plant and equipment accounts, while expenditures for maintenance and repairs and minor renewals are charged to expense. When assets are retired, the assets and related accumulated depreciation are removed from the accounts and any resulting gain or loss is reflected in the consolidated statements of operations.

Our supply chain team, and our suppliers, continue to manage numerous supply, production, and logistics obstacles. 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. Though these mitigation efforts have not had a material impact on our financial results, our continuing efforts may not be successful.

We design, develop, manufacture and sell automated test systems and robotics products. Our automated test systems are used to test semiconductors, wireless products, data storage and complex electronics systems in many industries including 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 automated test equipment and robotics products and services include: •semiconductor test (“Semiconductor Test”) systems; semiconductor test (“Semiconductor Test”) systems; •robotics (“Robotics”) products; and robotics (“Robotics”) products; and •defense/aerospace (“Defense/Aerospace”) test instrumentation and systems, circuit-board test and inspection (“Production Board Test”) systems, and wireless test systems (referred collectively as \"All Other\"). defense/aerospace (“Defense/Aerospace”) test instrumentation and systems, circuit-board test and inspection (“Production Board Test”) systems, and wireless test systems (referred collectively as \"All Other\"). 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 products both through direct sales and sales to the customer’s 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 2024, we saw strength in our Semiconductor Test business, with memory and compute offerings growing considerably compared to 2023. We expect mobile, automotive, and industrial will grow in 2025 and that recent advancements in AI inference may help mid-term recovery in these markets. Beyond AI compute, we are investing in other areas of the semiconductor test market that offer the opportunity for accelerating long-term growth, including power semi-conductors and the shift towards vertically integrated products (\"VIPs\"). We have seen the benefits start to materialize in 2024 and expect them to continue through the mid-term. 2024 was a very weak industrial automation market resulting in a year-over-year decline in Robotics revenues while outperforming our peer group. In 2024, we built key OEM, systems integrators and large account strategic partnerships which will strengthen our go to market for years to come. Introduction of new products, including the MiR 1200 Pallet Jack will further expand our available markets to support our growth. On May 27, 2024, we paid 483.1 million Euros, equivalent to $524.1 million, to purchase a combination of previously issued and outstanding shares and shares newly issued by Technoprobe, S.p.A. (\"Technoprobe\"). The shares purchased represent 10% of the issued and outstanding shares of Technoprobe. We also received a board seat as part of the purchase. Additionally, as part of the transaction, we completed the sale of the Device Interface Solutions (\"DIS\") business, a component of our Semiconductor Test segment, to Technoprobe for $85.0 million in cash, net of cash and cash equivalents sold, and a customary working capital adjustment. The sale resulted in a pre-tax gain of $57.1 million recorded as 'Gain on sale of business' in the consolidated statement of operations. Our financial statements are denominated in U.S. dollars. While revenues in our test businesses are predominantly in U.S. dollars, the majority of our Robotics revenue is denominated in foreign currencies. Strengthening of the U.S. dollar would negatively affect Robotics revenue growth in 2025. Our corporate strategy for our test businesses is to profitably grow market share while in Robotics, we plan to profitably grow revenue through the introduction of differentiated products targeting expanding markets.

A few customers drive significant demand for our products both through direct sales and sales to the customer’s 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 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 continued to drive demand for our products in the memory market in 2023. 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 Semiconductor 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. Demand in the fourth quarter of 2023 increased, tied to introduction of new products and seasonally high demand in Robotics after market softness and the impact of our channel transformation resulted in a weaker than forecasted first half of 2023. On November 7, 2023, Teradyne and Technoprobe S.p.A, (“Technoprobe”), a leader in the design and production of probe cards, announced establishment of a strategic partnership that will seek to accelerate growth for both companies and enable higher performance semiconductor test interfaces for customers worldwide. As part of the partnership, Teradyne will make an investment of 481.0 million Euros in exchange for a 10% equity investment in Technoprobe and Technoprobe will acquire 100% of Teradyne’s Device Interface Solutions (\"DIS\") business in exchange for $85.0 million. The transaction is expected to close during the first half of 2024. In 2023, inflation had minimal effect on our results. While both our test and robotics businesses may continue to be influenced by supply constraints, which could impact our revenue and costs, We do not anticipate that supply chain constraints will have a material impact on our financial results in 2024. 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. There was no material impact to our 2023 results due to changes in foreign exchange rates, however, in 2022, the strengthening of the U.S. dollar was a factor in lower than forecasted revenues in our Robotics segment. Continued strengthening of the U.S. dollar would adversely affect Robotics revenue growth in 2024. 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 continue investing in our growth while balancing capital allocations between stock repurchases and dividends and using capital for acquisitions. 25 25 Table of Contents Table of Contents Table of Contents"

In order to be distinct, the product or service must perform either on its own or with readily available resources and must be separate within the context of the contract. 45 Table of Contents •Teradyne determines the transaction price to be the amount of consideration to which Teradyne expects to be entitled to, which is generally at contractually stated prices.•Transaction price is allocated to each individual performance obligation based on the standalone selling price of that performance obligation. Teradyne uses standalone transactions when available to value each performance obligation. If standalone transactions are not available, Teradyne will estimate the standalone selling price through market assessments or cost plus a reasonable margin analysis. Any discounts from standalone selling price are spread proportionally to each performance obligation. •In order to determine the appropriate timing for revenue recognition, Teradyne first determines if the transaction meets any of three criteria for over time recognition. If the transaction meets the criteria for over time recognition, Teradyne recognizes revenue as the good or service is delivered. Teradyne uses input variables such as hours or months utilized or costs incurred to determine the amount of revenue to recognize in a given period. Input variables are used as they best align consumption with benefit to the customer. For transactions that do not meet the criteria for over time recognition, Teradyne will recognize revenue at a point in time based on an assessment of the five criteria for transfer of control. Teradyne has concluded that revenue should be recognized when shipped or delivered based on contractual terms. Typically, acceptance of Teradyne’s products and services is a formality as Teradyne delivers similar systems, instruments and robots to standard specifications. In cases where acceptance is not deemed a formality, Teradyne will defer revenue recognition until customer acceptance. Performance Obligations Products Teradyne products consist primarily of semiconductor test systems and instruments, defense/aerospace test instrumentation and systems, storage test systems and instruments, circuit-board test and inspection systems and instruments, wireless test systems and robotics products. Teradyne’s hardware is typically recognized at a point in time upon transfer of control to the customer. Services Teradyne services consist of extended warranties, training and application support, service agreements, post contract customer support (“PCS”) and replacement parts. Each service is recognized based on relative standalone selling price. Extended warranty, training and support, service agreements and PCS are recognized over time based on the period of service. Replacement parts are recognized at a point in time upon transfer of control to the customer. Teradyne does not allow customer returns or provide refunds to customers for any products or services. Teradyne products include a standard 12-month warranty. This warranty is not considered a distinct performance obligation because it does not obligate Teradyne to provide a separate service to the customer and it cannot be purchased separately. Cost related to warranties are included in cost of revenues when product revenues are recognized. As of December 31, 2023 and 2022, deferred revenue and customer advances consisted of the following and are included in the short and long-term deferred revenue and customer advances: 2023 2022 (in thousands) Maintenance, service and training $ 66,458 $ 78,089 Customer advances, undelivered elements and other 35,731 59,147 Extended warranty 34,897 56,180 Total deferred revenue and customer advances $ 137,086 $ 193,416"

See Note E: \"Dispositions\" for additional information.Retirement and Postretirement Plans Teradyne recognizes net actuarial gains and losses and the change in the fair value of the plan assets in its operating results in the year in which they occur or upon any interim remeasurement of the plans. Teradyne calculates the expected return on plan assets using the fair value of the plan assets. Actuarial gains and losses are generally measured annually as of December 31 and, accordingly, recorded during the fourth quarter of each year or upon any interim remeasurement of the plans. Teradyne reports net periodic pension cost and net periodic postretirement benefit costs in accordance with ASU 2017-07, “Compensation—Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost.” The service cost component of net benefit costs is reported in the same line item in the consolidated statement of operations as other employee compensation costs. The non-service components of net benefit costs such as interest cost, expected return on assets, amortization of prior service cost, and actuarial gains or losses, are reported within other (income) expense, net. Goodwill, Intangible and Long-Lived Assets Teradyne accounts for goodwill and intangible assets in accordance with ASC 350-10, “Intangibles-Goodwill and Other.” Intangible assets are amortized over their estimated useful economic life and are carried at cost less accumulated amortization. Goodwill is assessed for impairment at least annually in the fourth quarter, as of December 31, on a reporting unit basis, or more frequently when events and circumstances occur indicating that the recorded goodwill may be impaired. In accordance with ASC 350-10, Teradyne has the option to perform a qualitative assessment to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If Teradyne determines this is the case, Teradyne is required to perform a quantitative goodwill impairment test to identify potential goodwill impairment and measure the amount of goodwill impairment loss to be recognized. If Teradyne determines that it is more likely than not that the fair value of the reporting unit is greater than its carrying amounts, a quantitative goodwill impairment test is not required. In accordance with ASC 360-10, “Impairment or Disposal of Long-Lived 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. Each impairment test is based on a comparison of the estimated undiscounted cash flows to the recorded value of the asset. If impairment is indicated, the asset is written down to its estimated fair value based on a discounted cash flows analysis. The cash flows estimates used to determine the impairment, if any, contain management’s best estimates using appropriate assumptions and projections at that time. Business Combination Teradyne recognizes the tangible and intangible assets acquired and liabilities assumed based on their estimated fair values at the date of acquisition. The fair value of identifiable intangible assets is based on detailed cash flows valuations that use information and assumptions provided by management. Teradyne uses all pertinent information known at the time of acquisition to estimate the fair value of contingent consideration at the time of the acquisition using all pertinent information known to us at the time to assess the probability of payment of contingent amounts or through the use of a Monte Carlo simulation model. Teradyne allocates any excess purchase price over the fair value of the net tangible and intangible assets acquired and liabilities assumed to goodwill. The assumptions used in the valuations for our acquisitions may differ materially from actual results depending on performance of the acquired businesses and other factors. While Teradyne believes the assumptions used were appropriate, different assumptions in the valuation of assets acquired and liabilities assumed could have a material impact on the timing and extent of impact on our statements of operations. Goodwill is assigned to reporting units as of the date of the related acquisition.

B.ACCOUNTING POLICIES The consolidated financial statements include the accounts of Teradyne and its wholly owned subsidiaries. All significant intercompany balances and transactions are eliminated. Certain prior years’ amounts were reclassified to conform to the current year presentation. Preparation of Financial Statements and Use of Estimates The preparation of consolidated financial statements requires management to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure 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 judgments 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 Annual Report on Form 10-K. 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. Revenue Recognition Revenue from Contracts with Customers In accordance with ASC 606, Teradyne recognizes revenues, when or as control is transferred to a customer. Teradyne’s determination of revenue is dependent upon a five-step process outlined below. •Teradyne accounts for a contract with a customer when there is written approval, the contract is committed, the rights of the parties, including payment terms, are identified, the contract has commercial substance and consideration is probable of collection. •Teradyne periodically enters into contracts with customers in which a customer may purchase a combination of goods and services, such as products with extended warranty obligations. Teradyne determines performance obligations by assessing whether the products or services are distinct from the other elements of the contract. In order to be distinct, the product or service must perform either on its own or with readily available resources and must be separate within the context of the contract. 45 Table of Contents •Teradyne determines the transaction price to be the amount of consideration to which Teradyne expects to be entitled to, which is generally at contractually stated prices.•Transaction price is allocated to each individual performance obligation based on the standalone selling price of that performance obligation. Teradyne uses standalone transactions when available to value each performance obligation. If standalone transactions are not available, Teradyne will estimate the standalone selling price through market assessments or cost plus a reasonable margin analysis. Any discounts from standalone selling price are spread proportionally to each performance obligation. •In order to determine the appropriate timing for revenue recognition, Teradyne first determines if the transaction meets any of three criteria for over time recognition. If the transaction meets the criteria for over time recognition, Teradyne recognizes revenue as the good or service is delivered. Teradyne uses input variables such as hours or months utilized or costs incurred to determine the amount of revenue to recognize in a given period. Input variables are used as they best align consumption with benefit to the customer. For transactions that do not meet the criteria for over time recognition, Teradyne will recognize revenue at a point in time based on an assessment of the five criteria for transfer of control. Teradyne has concluded that revenue should be recognized when shipped or delivered based on contractual terms. Typically, acceptance of Teradyne’s products and services is a formality as Teradyne delivers similar systems, instruments and robots to standard specifications. In cases where acceptance is not deemed a formality, Teradyne will defer revenue recognition until customer acceptance. Performance Obligations Products Teradyne products consist primarily of semiconductor test systems and instruments, defense/aerospace test instrumentation and systems, storage test systems and instruments, circuit-board test and inspection systems and instruments, wireless test systems and robotics products. Teradyne’s hardware is typically recognized at a point in time upon transfer of control to the customer. Services Teradyne services consist of extended warranties, training and application support, service agreements, post contract customer support (“PCS”) and replacement parts. Each service is recognized based on relative standalone selling price. Extended warranty, training and support, service agreements and PCS are recognized over time based on the period of service. Replacement parts are recognized at a point in time upon transfer of control to the customer. Teradyne does not allow customer returns or provide refunds to customers for any products or services. Teradyne products include a standard 12-month warranty. This warranty is not considered a distinct performance obligation because it does not obligate Teradyne to provide a separate service to the customer and it cannot be purchased separately. Cost related to warranties are included in cost of revenues when product revenues are recognized. As of December 31, 2023 and 2022, deferred revenue and customer advances consisted of the following and are included in the short and long-term deferred revenue and customer advances: 2023 2022 (in thousands) Maintenance, service and training $ 66,458 $ 78,089 Customer advances, undelivered elements and other 35,731 59,147 Extended warranty 34,897 56,180 Total deferred revenue and customer advances $ 137,086 $ 193,416 46 Table of Contents Product Warranty Teradyne generally provides a one-year warranty on its products, commencing upon installation, acceptance or shipment. A provision is recorded upon revenue recognition to cost of revenues for estimated warranty expense based on historical experience. Related costs are charged to the warranty accrual as incurred.

Teradyne maintains allowances for estimated losses resulting from the inability of its customers to make required payments. Estimated allowances for credit losses are reviewed periodically taking into account the customer’s recent payment history, the customer’s current financial statements and other information regarding the customer’s creditworthiness. Account balances are written off against the allowance when it is determined the receivable will not be recovered. Teradyne sells certain trade accounts receivables on a non-recourse basis to third-party financial institutions pursuant to factoring agreements. Teradyne accounts for these transactions as sales of receivables and presents cash proceeds as a cash provided by operating activities in the consolidated statements of cash flows. Total trade accounts receivable sold under the factoring agreements were $243.5 million and $93.9 million during 2023 and 2022, respectively. Factoring fees for the sales of receivables are recorded in interest expense and are not material. 47 Table of Contents Inventories Inventories are stated at the lower of cost (first-in, first-out basis) or net realizable value. On a quarterly basis, Teradyne uses consistent methodologies to evaluate all inventories for net realizable value. Teradyne records a provision for both excess and obsolete inventory when such write-downs or write-offs are identified through the quarterly review process. The inventory valuation is based upon assumptions about future demand, product mix and possible alternative uses. Investments Teradyne accounts for its investments in debt and equity securities in accordance with the provisions of ASC 320-10, “Investments—Debt and Equity Securities.” ASC 320-10 requires that certain debt and equity securities be classified into one of three categories; trading, available-for-sale or held-to-maturity securities. On a quarterly basis, Teradyne reviews its investments to identify and evaluate those that have an indication of a potential other-than-temporary impairment. Factors considered in determining whether a loss is other-than-temporary include: •The length of time and the extent to which the market value has been less than cost; •The financial condition and near-term prospects of the issuer; and •The intent and ability to retain the investment in the issuer for a period of time sufficient to allow for any anticipated recovery in market value. Teradyne uses the market and income approach techniques to value its financial instruments and there were no changes in valuation techniques during the twelve months ended December 31, 2023 and 2022. Teradyne measures its debt and equity investments at fair value, in accordance with ASC 820-10, “Fair Value Measurements and Disclosures.” ASC 820-10 defines fair value as the price that would be received from the sale of an asset or paid to transfer a liability in an orderly transaction between market participants and requires that assets and liabilities carried at fair value be classified and disclosed in one of the following three categories: Level 1: Quoted prices in active markets for identical assets as of the reporting date; Level 2: Inputs other than Level 1, that are observable either directly or indirectly as of the reporting date. For example, a common approach for valuing fixed income securities is the use of matrix pricing. Matrix pricing is a mathematical technique used to value securities by relying on the securities’ relationship to other benchmark quoted prices, and is considered a Level 2 input; or Level 3: Unobservable inputs that are not supported by market data. Unobservable inputs are developed based on the best information available, which might include Teradyne’s own data. Teradyne’s debt investments are classified as Level 2, and equity investments are classified as Level 1. Acquisition-related contingent consideration is classified as Level 3. Teradyne determines the fair value of acquisition-related contingent consideration using a Monte Carlo simulation model. Assumptions utilized in the model include forecasted revenues, revenue volatility, earnings before interest and taxes, and discount rate. Financial Assets and Financial Liabilities Teradyne records changes in fair value of equity securities directly in earnings and unrealized gains and losses in other (income) expense, net, in accordance with ASU 2016-01, “Financial Instruments—Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities.” 48 Table of Contents Prepayments Prepayments consist of the following: 2023 (1) 2022 (in thousands) Contract manufacturer and supplier prepayments $ 502,257 $ 491,105 Prepaid maintenance and other services 17,592 14,545 Prepaid taxes 16,083 18,625 Other prepayments 13,038 8,687 Total prepayments $ 548,970 $ 532,962 (1)Excludes $5.3 million of contract manufacturer and supplier prepayments, classified as assets held for sale. See Note E: “Assets held for sale” for additional information.Retirement and Postretirement Plans Teradyne recognizes net actuarial gains and losses and the change in the fair value of the plan assets in its operating results in the year in which they occur or upon any interim remeasurement of the plans. Teradyne calculates the expected return on plan assets using the fair value of the plan assets. Actuarial gains and losses are generally measured annually as of December 31 and, accordingly, recorded during the fourth quarter of each year or upon any interim remeasurement of the plans. Teradyne reports net periodic pension cost and net periodic postretirement benefit costs in accordance with ASU 2017-07, “Compensation—Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost.” The service cost component of net benefit costs is reported in the same line item in the consolidated statement of operations as other employee compensation costs. The non-service components of net benefit costs such as interest cost, expected return on assets, amortization of prior service cost, and actuarial gains or losses, are reported within other (income) expense, net. Goodwill, Intangible and Long-Lived Assets Teradyne accounts for goodwill and intangible assets in accordance with ASC 350-10, “Intangibles-Goodwill and Other.” Intangible assets are amortized over their estimated useful economic life and are carried at cost less accumulated amortization. Goodwill is assessed for impairment at least annually in the fourth quarter, as of December 31, on a reporting unit basis, or more frequently when events and circumstances occur indicating that the recorded goodwill may be impaired. In accordance with ASC 350-10, Teradyne has the option to perform a qualitative assessment to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If Teradyne determines this is the case, Teradyne is required to perform a quantitative goodwill impairment test to identify potential goodwill impairment and measure the amount of goodwill impairment loss to be recognized. If Teradyne determines that it is more likely than not that the fair value of the reporting unit is greater than its carrying amounts, a quantitative goodwill impairment test is not required. In accordance with ASC 360-10, “Impairment or Disposal of Long-Lived 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. Each impairment test is based on a comparison of the estimated undiscounted cash flows to the recorded value of the asset. If impairment is indicated, the asset is written down to its estimated fair value based on a discounted cash flows analysis. The cash flows estimates used to determine the impairment, if any, contain management’s best estimates using appropriate assumptions and projections at that time. Business Combination Teradyne recognizes the tangible and intangible assets acquired and liabilities assumed based on their estimated fair values at the date of acquisition. The fair value of identifiable intangible assets is based on detailed cash flows valuations that use information and assumptions provided by management. Teradyne estimates the fair value of contingent consideration at the time of the acquisition using all pertinent information known to us at the time to assess the probability of payment of contingent amounts or through the use of a Monte Carlo simulation model. Teradyne allocates any excess purchase price over the fair value of the net tangible and intangible assets acquired and liabilities assumed to goodwill. The assumptions used in the valuations for our acquisitions may differ materially from actual results depending on performance of the acquired businesses and other factors. While Teradyne believes the assumptions used were appropriate, different assumptions in the valuation of assets acquired and liabilities assumed could have a material impact on the timing and extent of impact on our statements of operations. Goodwill is assigned to reporting units as of the date of the related acquisition. 49 Table of Contents Property, Plant and Equipment Property, plant and equipment are stated at cost and depreciated over the estimated useful lives of the assets. Leasehold improvements and major renewals are capitalized and included in property, plant and equipment accounts, while expenditures for maintenance and repairs and minor renewals are charged to expense. When assets are retired, the assets and related accumulated depreciation are removed from the accounts and any resulting gain or loss is reflected in the consolidated statements of operations. Teradyne provides for depreciation of its assets principally on the straight-line method with the cost of the assets being charged to expense over their useful lives as follows: Buildings 40 years Building improvements 5 to 10 years Leasehold improvements Lesser of lease term or 10 years Furniture and fixtures 10 years Test systems manufactured internally 6 years Machinery, equipment and software 3 to 5 years Test systems manufactured internally are used by Teradyne for customer evaluations and manufacturing and support of its customers. Teradyne depreciates the test systems manufactured internally over a six-year life to cost of revenues, engineering and development, and selling and administrative expenses. Teradyne often sells internally manufactured test equipment to customers. Upon the sale of an internally manufactured test system, the net book value of the system is transferred to inventory and expensed as cost of revenues. The net book value of internally manufactured test systems sold in the years ended December 31, 2023, 2022, and 2021 was $2.8 million, $6.6 million, and $16.6 million, respectively. Convertible Debt Teradyne adopted Accounting Standards Update (“ASU”) ASU 2020-06 – “Debt—Debt with Conversion and Other Options and Derivatives and Hedging—Contracts in Entity’s Own Equity,” on January 1, 2022 using the modified retrospective method of adoption. As a result of 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. In accordance with ASU 2020-06, Teradyne accounts for a convertible debt instrument as a single liability measured at its amortized cost, as long as no other features require bifurcation and recognition as derivatives. Unsettled shares are recorded in current debt, and there is no recognition of a debt discount, which was previously amortized to interest expense. Settled shares reduce the outstanding debt balance in an amount equal to the cash paid, but do not result in any gain or loss on extinguishment. We use the if-converted method in the diluted EPS calculation for convertible instruments. Leases Under ASC 842, a contract is or contains a lease when Teradyne has the right to control the use of an identified asset. Teradyne determines if an arrangement is a lease at inception of the contract, which is the date on which the terms of the contract are agreed to and the agreement creates enforceable rights and obligations. The commencement date of the lease is the date that the lessor makes an underlying asset available for use by Teradyne. As of December 31, 2023, Teradyne does not have material leases that have not yet commenced. Teradyne determines if the lease is an operating or finance lease at the lease commencement date based upon the terms of the lease and the nature of the asset. The lease term used to calculate the lease liability includes options to extend or terminate the lease when it is reasonably certain that the option will be exercised. The lease liability is measured at the present value of future lease payments, discounted using the discount rate for the lease at the commencement date. As Teradyne is typically unable to determine the implicit rate, Teradyne uses an incremental borrowing rate based on the lease term and economic environment at commencement date. Teradyne initially measures payments based on an index by using the applicable rate at lease commencement. Variable payments that do not depend on an index are not included in the lease liability and are recognized as they are incurred. The right-of-use (“ROU”) asset is initially measured as the amount of lease liability, adjusted for any initial lease costs, prepaid lease payments, and reduced by any lease incentives. 50 Table of Contents Teradyne’s contracts often include non-lease components such as common area maintenance. Teradyne elected the practical expedient to account for the lease and non-lease components as a single lease component. For leases with a term of one year or less, Teradyne has elected not to record the lease asset or liability. The lease payments are recognized in the consolidated statement of earnings on a straight-line basis over the lease term. Teradyne includes lease costs within cost of revenues and operating expenses. See Note I: “Leases.” Engineering and Development Costs Teradyne’s products are highly technical in nature and require a large and continuing engineering and development effort. Software development costs incurred prior to the establishment of technological feasibility are charged to expense. Software development costs incurred subsequent to the establishment of technological feasibility are capitalized until the product is available for release to customers. To date, the period between achieving technological feasibility and general availability of the product has been short and software development costs eligible for capitalization have not been material. Engineering and development costs are expensed as incurred and consist primarily of salaries, contractor fees including non-recurring engineering charges related to product design, allocated facility costs, depreciation, and tooling costs. Stock Compensation Plans and Employee Stock Purchase Plan Stock-based compensation expense is based on the grant-date fair value estimated in accordance with the provisions of ASC 718-10, “Compensation-Stock Compensation.” Teradyne elects to account for forfeitures by applying an estimated forfeiture rate and recognizes compensation costs only for those stock-based compensation awards expected to vest. Under its stock compensation plans, Teradyne has granted stock options, restricted stock units and performance-based restricted stock units, and employees are eligible to purchase Teradyne’s common stock through its Employee Stock Purchase Plan (“ESPP”). Excess tax benefits or tax deficiencies are recognized as a discrete tax benefit or discrete tax expense to the current income tax provision in Teradyne’s consolidated statements of operations, all excess tax benefits related to share-based payments are reported as cash flows from operating activities, and all cash payments made to taxing authorities on the employees’ behalf for withheld shares are presented as financing activities on the statement of cash flows. Income Taxes Deferred tax assets and liabilities are determined based on differences between financial reporting and tax basis of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. The measurement of deferred tax assets is reduced by a valuation allowance if it is more likely than not that some or all of the deferred tax assets will not be realized. Teradyne performed the required assessment of positive and negative evidence regarding the realization of the net deferred tax assets in accordance with ASC 740, “Accounting for Income Taxes.” This assessment included the evaluation of scheduled reversals of deferred tax liabilities, estimates of projected future taxable income and tax-planning strategies. Although realization is not assured, based on its assessment, Teradyne concluded that it is more likely than not that such assets, net of the existing valuation allowance, will be realized. Advertising Costs Teradyne expenses all advertising costs as incurred. Advertising costs were $15.5 million, $17.3 million and $13.4 million in 2023, 2022 and 2021, respectively. Translation of Non-U.S. Currencies The functional currency for all non-U.S. subsidiaries is the U.S. dollar, except for Universal Robots, MiR and Lemsys for which the local currency is its functional currency. All foreign currency denominated monetary assets and liabilities are remeasured on a monthly basis into the functional currency using exchange rates in effect at the end of the period. All foreign currency denominated non-monetary assets and liabilities are remeasured into the functional currency using historical exchange rates. Net foreign exchange gains and losses resulting from remeasurement are included in other (income) expense, net. For Universal Robots, MiR and Lemsys, assets and liabilities are translated into U.S. dollars using exchange rates in effect at the end of the period. Revenues and expense amounts are translated using an average of exchange rates in effect during the period. Translation adjustments are recorded within accumulated other comprehensive income (loss) on the balance sheet. Net foreign exchange gains and losses resulting from remeasurement are included in other (income) expense, net. For the years ended December 31, 2023, 2022 and 2021, losses (gains) from the remeasurement of the monetary assets and liabilities denominated in foreign currencies were $10.9 million, $10.8 million, and $(2.1) million, respectively. 51 Table of Contents These amounts do not reflect the corresponding (gains) losses from foreign exchange contracts. See Note H: “Financial Instruments” regarding foreign exchange contracts. Net Income per Common Share Basic net income per common share is calculated by dividing net income by the weighted average number of common shares outstanding during the period. Except where the result would be anti-dilutive, diluted net income per common share is calculated by dividing net income by the sum of the weighted average number of common shares plus common stock equivalents, if applicable. With respect to its convertible debt issued in 2016, Teradyne is required to settle the principal of the convertible debt in cash; accordingly, the principal amount is excluded from the determination of diluted earnings per share. As a result, Teradyne is accounting for the conversion spread using the treasury stock method. Comprehensive Income Comprehensive income includes net income, unrealized pension and postretirement prior service costs and benefits, unrealized gains and losses on investments in debt marketable securities, unrealized gains and losses on cash flow hedge and foreign currency translation adjustment."

Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk.

Impairment of intangible and long-lived assets would result in the asset being written down to its estimated fair value.

DCF models rely on our forecasted mid-term plans which are subjective based on customer or market conditions and can change materially.

The measurement of deferred tax assets is reduced by a valuation allowance if it is more likely than not that some or all of the deferred tax assets will not be realized. Teradyne performed the required assessment of positive and negative evidence regarding the realization of the net deferred tax assets in accordance with ASC 740, “Accounting for Income Taxes.” This assessment included the evaluation of scheduled reversals of deferred tax liabilities, estimates of projected future taxable income and tax-planning strategies.

We evaluate our discount rate and expected rate of return on assets assumptions annually on a plan and country specific basis.

In developing the expected return on U.S. Qualified Pension Plan (“U.S. Plan”) assets assumption, we evaluated input from our investment manager and pension consultants, including their forecast of asset class return expectations. We believe that 4.65% was an appropriate rate of return on assets to use for 2024. The December 31, 2024 asset allocation for our U.S. Plan was 94% invested in fixed income securities, 5% invested in equity securities, and 1% invested in other securities. Our investment manager regularly reviews the actual asset allocation and periodically rebalances the portfolio to ensure alignment with our target allocations. The discount rate that we utilized for determining future pension obligations for the U.S. Plan is based on the FTSE Pension Index adjusted for the U.S. Plan’s expected cash flows and was 5.45% at December 31, 2024, up from 4.75% at December 31, 2023. We estimate that in 2025 we will recognize approximately $0.1 million of pension expense for the U.S. Plan. The U.S. Plan pension expense estimate for 2025 is based on a 5.45% discount rate and a 5.05% return on assets.

Teradyne depreciates the test systems manufactured internally over a six-year life to cost of revenues, engineering and development, and selling and administrative expenses. Teradyne often sells internally manufactured test equipment to customers. Upon the sale of an internally manufactured test system, the net book value of the system is transferred to inventory and expensed as cost of revenues. The net book value of internally manufactured test systems sold in the years ended December 31, 2024, 2023, and 2022 was $4.0 million, $2.8 million, and $6.6 million, respectively. six-year Convertible Debt Teradyne adopted Accounting Standards Update (“ASU”) ASU 2020-06 – “Debt—Debt with Conversion and Other Options and Derivatives and Hedging—Contracts in Entity’s Own Equity,” on January 1, 2022 using the modified retrospective method of adoption. As a result of 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. In accordance with ASU 2020-06, Teradyne accounts for a convertible debt instrument as a single liability measured at its amortized cost, as long as no other features require bifurcation and recognition as derivatives. Unsettled shares are recorded in current debt, and there is no recognition of a debt discount, which was previously amortized to interest expense. Settled shares reduce the outstanding debt balance in an amount equal to the cash paid, but do not result in any gain or loss on extinguishment. We use the if-converted method in the diluted EPS calculation for convertible instruments."

In certain foreign jurisdictions, we qualify for tax incentives and tax holidays based on our ability to meet, on a continuing basis, various tests relating to our employment levels, research and development expenditures and other qualification requirements in a particular foreign jurisdiction. While we intend to operate in such a manner to maintain and maximize our tax incentives and tax holidays, no assurance can be given that we have so qualified or that we will qualify for any particular year or jurisdiction. If we fail to qualify or fail to remain qualified for certain foreign tax incentives and tax holidays, we may be subject to further taxation or an increase in our effective tax rate which would adversely impact our financial results. In November 2020, we 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. The tax savings attributable to the Singapore tax holiday for the years ended December 31, 2024, 2023 and 2022 were $17.1 million or $0.10 per diluted share, $1.4 million or $0.01 per diluted share, and $16.0 million or $0.09 per diluted share, respectively. These tax savings may not be achievable in subsequent years due to changes in Singapore’s tax laws, issuance of new global minimum tax laws, or the expiration of the tax holiday. 12 12 12 Table of Contents Table of Contents Table of Contents In addition, we may incur additional costs, including headcount expenses, in order to maintain or obtain a foreign tax incentive or tax holiday in a particular foreign jurisdiction."

Revenue Recognition - Certain Product Revenue As described in Note B to the consolidated financial statements, the Company recognizes revenue for transactions that do not meet the criteria for over time recognition, at a point in time when shipped or delivered based on contractual terms. The transaction price is the amount of consideration the Company expects to be entitled to in exchange for such products, which is generally at contractually stated prices. The Company’s total product revenue was $2.3 billion for the year ended December 31, 2024, of which a majority relates to certain product revenue. The principal consideration for our determination that performing procedures relating to revenue recognition for certain product revenue is a critical audit matter is a high degree of auditor effort in performing procedures related to revenue recognition for certain of the Company’s product revenue. Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements.

On a quarterly basis, Teradyne reviews its investments to identify and evaluate those that have an indication of a potential other-than-temporary impairment. Factors considered in determining whether a loss is other-than-temporary include: •The length of time and the extent to which the market value has been less than cost; The length of time and the extent to which the market value has been less than cost; •The financial condition and near-term prospects of the issuer; and The financial condition and near-term prospects of the issuer; and •The intent and ability to retain the investment in the issuer for a period of time sufficient to allow for any anticipated recovery in market value. The intent and ability to retain the investment in the issuer for a period of time sufficient to allow for any anticipated recovery in market value. Teradyne uses the market and income approach techniques to value its financial instruments and there were no changes in valuation techniques during the twelve months ended December 31, 2024 and 2023. Teradyne measures its debt and equity investments at fair value, in accordance with ASC 820-10, “Fair Value Measurements and Disclosures.” ASC 820-10 defines fair value as the price that would be received from the sale of an asset or paid to transfer a liability in an orderly transaction between market participants and requires that assets and liabilities carried at fair value be classified and disclosed in one of the following three categories: Level 1: Quoted prices in active markets for identical assets as of the reporting date; Level 2: Inputs other than Level 1, that are observable either directly or indirectly as of the reporting date. For example, a common approach for valuing fixed income securities is the use of matrix pricing. Matrix pricing is a mathematical technique used to value securities by relying on the securities’ relationship to other benchmark quoted prices, and is considered a Level 2 input; or Level 3: Unobservable inputs that are not supported by market data. Unobservable inputs are developed based on the best information available, which might include Teradyne’s own data. Teradyne’s debt investments are classified as Level 2, and equity investments are classified as Level 1.

We also have audited the Company's internal control over financial reporting as of December 31, 2024, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2024 and 2023, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2024 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2024, based on criteria established in Internal Control - Integrated Framework (2013) issued by the COSO. Change in Accounting Principle As discussed in Note B to the consolidated financial statements, the Company changed the manner in which it accounts for convertible debt in 2022."

Our determination of revenue requires judgment in the determination of performance obligations and allocation of the transaction price to performance obligations. We often sell bundled orders that include both product and services or multiple different products within the same order. We evaluate each of the deliverables to determine if it meets the definition of a performance obligation, which requires that it is capable of being distinct and distinct within the context of the contract. This determination is based on an assessment of contractual rights of the contract and the ability of the performance obligation to perform on its own or with readily available resources. In bundled transactions we estimate the standalone selling price of each identified performance obligation and use that estimate to allocate the transaction price among said performance obligations. The estimated standalone selling price is determined using all information reasonably available to us, including standalone transactions, market information and other observable inputs."

      "current_body": "Our business is international in nature, with our sales, service and administrative personnel and our customers and suppliers located in numerous countries throughout the world. Our operations, and those of our customers and suppliers, are subject to disruption for a variety of reasons, including work stoppages, acts of war, terrorism, health epidemics, fires, earthquakes, hurricanes, typhoons, volcanic eruptions, energy shortages, telecommunication failures, tsunamis, flooding or other natural disasters. Such disruption could materially increase our costs and expenses as well as cause delays in, among other things, shipments of products to our customers, our ability to perform services requested by our customers, or the installation and acceptance of our products at customer sites. Any of these conditions could have a material adverse effect on our business, financial condition or results of operations. Global climate change can result in natural disasters occurring more frequently, with greater intensity and with less predictability. For example, when our operations in Cebu, Philippines experienced a devastating typhoon, our employees in Cebu succeeded in restoring most of our operations within days despite the severity of the damage in the region. The long-term effects of climate change on the global economy and the semiconductor industry in particular are unclear but could be severe."

      "current_body": "Financial instruments which potentially subject us to concentrations of credit risk consist principally of cash equivalents, marketable securities, forward currency contracts and accounts receivable. Our cash equivalents consist primarily of money market funds invested in U.S. Treasuries and government agencies. Our fixed income available-for-sale marketable securities have a minimum rating of AA by one or more of the major credit rating agencies. We place forward currency contracts with high credit-quality financial institutions in order to minimize credit risk exposure. Concentrations of credit risk with respect to accounts receivable are limited due to the large number of geographically dispersed customers. We perform ongoing credit evaluations of our customers’ financial condition and from time to time may require customers to provide a letter of credit from a bank to secure accounts receivable. As of December 31, 2024, two customers of our Semiconductor Test segment, Taiwan Semiconductor Manufacturing Co. and SK Hynix Inc, each accounted for 10% of our accounts receivable balance. As of December 31, 2023, a customer of our Semiconductor Test segment, Texas Instruments Inc., accounted for 18% of our accounts receivable balance."

      "current_body": "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. As further described below, compliance with these laws has not significantly limited our sales over time, but could significantly limit them in the future. Changes in, and responses to, U.S. trade policy could reduce the 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, foreign made product which was produced using U.S. technology, 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 and the Foreign Direct Product Rule (\"FDP\") under U.S. Export Administration Regulations (“EAR”). On May 16, 2019, Huawei and 68 of its affiliates, including HiSilicon, were added to the U.S. Department of Commerce Entity List under EAR. On December 2, 2024, certain of our customers and prospective customers were added to the U.S. Department of Commerce Entity List or FDP under EAR. The addition of certain of these companies to the entity list and FDP 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 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 to ensure compliance and 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 took effect on November 17, 2023, significantly limit the impact of the October 7, 2022 restrictions on our business. On December 2, 2024, the U.S. Department of Commerce released additional new rules updating export controls. These 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."

In accordance with ASU 2020-06, we account for a convertible debt instrument as a single liability measured at its amortized cost, as long as no other features require bifurcation and recognition as derivatives. Unsettled shares are recorded in current debt, and there is no recognition of a debt discount, which was previously amortized to interest expense. Settled shares reduce the outstanding debt balance in an amount equal to the cash paid, but do not result in any gain or loss on extinguishment. We use the if-converted method in the diluted EPS calculation for convertible instruments."
