02AddedItem 1A › Risks Related to Intellectual Property ("IP") and Cybersecurity › A breach of our operational or security systems could negatively affect our business and results of operations.

Summary · quote-checked

Added a risk disclosure covering operational and cybersecurity breaches, supplier and service-provider dependencies, compliance costs, and potential legal and reputational consequences.

The new paragraph introduces substantive risks, obligations, dependencies, and consequences rather than changing existing wording or formatting.

Why the model ranked it here

We rely on various information technology networks and systems to process, transmit and store electronic information, including proprietary and confidential data, and to carry out and support a variety of business activities, including manufacturing, research and development, supply chain management, sales and accounting. We have experienced several attempted cyber-attacks of our network. None of the attempted attacks have caused a disruption to our operations or had a material adverse effect on our business or financial results. As a result of the attempts, we have taken further preventive security measures to protect our systems. Despite the preventive security measures we have implemented, we may continue to be vulnerable to attempts by third parties to gain unauthorized access to our networks or sabotage our systems. These attempts, which might be related to criminal hackers, industrial espionage or state-sponsored intrusions, include trying to covertly introduce malware to our computers, networks and systems and impersonating authorized users. Additionally, evolving geopolitical tensions or conflicts have created a heightened risk of cybersecurity attacks. In addition, third party suppliers and service providers that we rely on to manage our networks and systems and who process and store our proprietary and confidential data, including the data of our customers and suppliers, may also be subject to similar attacks. Employees and contractors may also attempt to gain unauthorized access to our systems and steal proprietary and confidential data. Such attempts could result in the misappropriation, theft, misuse, disclosure or loss or destruction of the intellectual property, or the proprietary, confidential or personal information, of Teradyne or our employees, customers, suppliers or other third parties, as well as damage to or disruptions in our information technology networks and systems. These threats are constantly evolving and expanding, such as through the increased use of artificial intelligence in our products and expanding remote work opportunities for our employees, thereby increasing the difficulty of defending against them or implementing adequate preventative measures. Attempts to gain unauthorized access to our information technology networks and systems may be successful, and in some cases, we might be unaware of an incident or its magnitude and effects. [added] A failure in or a breach of our operational or security systems or infrastructure, or those of our suppliers and other service providers, including as a result of cyber-attacks, could have a material adverse effect on our business or financial results, disrupt our business, result in the disclosure or misuse of proprietary or confidential information, damage our reputation, cause losses and increase our costs. We expect to continue to devote significant resources to the security of our information technology networks and systems. Furthermore, our efforts to comply with evolving laws and regulations related to cybersecurity may be costly and any failure to comply could result in investigations, proceedings, investor lawsuits and reputational damage.

Summary · quote-checked

Added a risk describing acquisition underperformance, related charges, impairment, and potential adverse effects on financial position and operating results.

The new paragraph discloses substantive acquisition, goodwill, intangible-asset, and contingent-consideration risks, including potential charges affecting results and financial position.

[added] Following an acquisition, we may not achieve the revenue or net income levels that justify the acquisition. Acquisitions may also result in one-time charges (such as acquisition-related expenses, write-offs or restructuring charges) or in the future, impairment of goodwill or acquired intangible assets, or adjustments to contingent consideration liabilities that adversely affect our operating results. We review our amortizable intangible assets for impairment at the reporting unit level when events or changes in circumstances indicate the carrying value may not be recoverable and we test goodwill for impairment at least annually. Factors that may be considered in assessing whether goodwill or intangible assets may be impaired include a decline in our stock price or market capitalization, reduced estimates of reporting unit future cash flows and slower growth rates in our industries. We have in the past recorded, and may in the future be required to record, a significant charge in our consolidated financial statements during the period in which any impairment of our goodwill or amortizable intangible assets is determined, negatively affecting our financial position and results of operations. Our valuation methodology for assessing impairment requires management to make judgments and assumptions based on experience and to rely heavily on projections of future operating performance. Because we operate in highly competitive environments, projections of our future operating results and cash flows may vary significantly from our actual results.

Summary · quote-checked

Removed disclosure that Samsung-related revenues accounted for 12.5% of consolidated revenues in 2024.

The removed paragraph disclosed a specific customer concentration and revenue dependency, which is a substantive risk-factor disclosure under the rubric.

Why the model ranked it here

The removed disclosure eliminates visibility into dependence on a major customer and the potential effect of that relationship on consolidated revenue.

02RemovedItem 1A › Risks Related to Legal and Regulatory Compliance › The implementation of tariffs on our products may have a material impact on our business.

Summary · quote-checked

Removed disclosure about newly imposed or proposed tariffs and their potential effects on the business.

The removed paragraph identified specific tariff actions, jurisdictions, ongoing evaluation, and potential business effects, constituting a substantive regulatory risk disclosure rather than wording or boilerplate.

Why the model ranked it here

The removed disclosure concerned newly imposed or proposed tariffs and their possible effects on the company’s business, removing a current regulatory exposure from view.

Filing text · FY2024 10-K · filed Feb 20, 2025

[removed] In February, 2025, President Trump issued executive orders directing the United States to impose new or additional tariffs on certain imports from Canada, Mexico and China and subsequently announced his intention to pause such tariffs on Canada and Mexico. While we do not believe any tariffs announced to date will have a material adverse effect on our business, financial condition or results of operations, we are still evaluating the potential impact of these tariffs and any additional tariffs implemented by the Trump administration as well as any retaliatory actions by the impacted countries to our business and financial condition and outlook. The actual impact on any new tariffs is subject to a number of factors including the effective date, duration, amount, scope and nature of the tariffs, any retaliatory actions any impacted country may take, and any mitigating actions that are available.

01RemovedItem 7 › Supply Chain Constraints and Inflationary Pressures

Summary · quote-checked

Removed disclosure describing past supply shortages, inflationary cost pressures, and the expectation that supply constraints would not materially affect 2025 financial results.

The removed paragraph disclosed supply-chain exposure, inflationary effects, historical impacts, and management’s forward-looking assessment; its deletion changes the substance of the MD&A disclosure.

Why the model ranked it here

Removing the supply-chain and inflation discussion eliminates management’s stated assessment of operational exposure and expected financial effects.

Filing text · FY2024 10-K · filed Feb 20, 2025

[removed] The global supply shortage of electrical components, including semiconductor chips, impacted our supply chain in the first half of 2023. In the second half of 2023 and the full year of 2024, we saw improvements related to supply constraints and, consequently, did not experience material increases in our lead times and costs for components. In addition, in 2023 and 2024, inflationary pressures contributed to increased costs for product components and wage inflation, which had a minimal impact on our cost of products, gross margin and profit for the year. While our businesses could be impacted by supply constraints in the future, we do not anticipate supply chain constraints will have a material impact on our financial results in 2025.

02RemovedItem 7 › Gross Profit

Summary · quote-checked

The current filing omits the paragraph describing quarterly inventory valuation, obsolete inventory reserves, and excess inventory write-downs.

The removed paragraph discloses inventory valuation procedures and accounting treatment for obsolete and excess inventory, representing substantive information about an obligation and exposure.

Why the model ranked it here

Removing the inventory-reserve policy obscures how obsolete and excess inventory exposures are identified and measured.

Filing text · FY2024 10-K · filed Feb 20, 2025

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

Removed disclosure of convertible debt payments, employee compensation settlement payments, and common-stock issuance proceeds.

The removed text describes specific cash uses and an offsetting financing source, changing the disclosed cash-flow activity rather than merely updating wording or periods.

Why the model ranked it here

Removing the financing cash-flow discussion obscures debt repayments, employee-compensation settlements, and the offsetting stock-issuance proceeds.

Filing text · FY2024 10-K · filed Feb 20, 2025

The disclosure changes from fully repaid prior borrowings to later borrowings, partial repayment, and potential additional indebtedness.

Debt status, borrowing purposes, repayment status, and the possibility of significant additional indebtedness changed substantively, altering the disclosed financing exposure.

Summary · quote-checked

The disclosure identifies significant customers as global and reports higher five-largest-customer concentration, with the latest aggregate share increasing from 36% to 44%.

The updated concentration figure changes the stated exposure to customer dependency; the period roll-forward and “global” descriptor are secondary wording changes.

Why the model ranked it here

The company discloses a materially greater reliance on a concentrated group of significant customers, increasing dependence on customer demand.

Summary · quote-checked

The disclosure shifts from warranty, product liability, and recall risks to dependence on significant customers and limited contractual recourse.

A product-liability and recall risk was removed, while a customer-concentration dependency and potential revenue impact were added; both substantively change disclosed risks.

Why the model ranked it here

The company now highlights revenue exposure from losing significant customers while acknowledging limited contractual protection against abrupt purchasing decisions.

Filing text · FY2024 10-K · filed Feb 20, 2025

We invest significant resources in the design, manufacturing and testing of our products. However, from time to time, we discover design or manufacturing defects in our products after they have been shipped and, as a result, we have incurred development and remediation costs and settled warranty and product liability claims. In addition, when our products contain defects or have reliability, quality or safety issues, we have conducted a product recall which resulted in significant repair or replacement costs and [removed] substantial delays in product shipments and may damage our reputation which could make it more difficult to sell our products. We could continue to have warranty and product liability claims or product recalls in the future.
