In 2018, We cannot predict what further actions may ultimately be taken with respect to tariffs or what products or entities may be subject to such actions, or what reciprocation may be taken by other countries in response to U.S. actions. If we cannot find ways to mitigate the United States Trade Representative imposed potential impacts from these tariffs successfully or in a 25% tariff timely manner, these additional tariffs and policies could have a significant impact on many lists our business and operating results. The actual impact on any new tariffs is subject to a number of products, factors including certain Teradyne products that are made in China the effective date, duration, amount, scope and imported into the United States. On February 1, 2025, President Trump issued an executive order directing the United States to impose an additional 10% tariff on all imports from China effective February 4, 2025.We plan to implement operational changes that mitigate some nature of the impact of these tariffs on the import of our impacted products into the United States. As a result, the existing tariffs tariffs. To date, recent tariff changes have not had a material adverse effect on our business, financial condition or results of operations. The operations, however, in the future, the implementation of additional tariffs by the United States or other countries could have a material adverse effect on our business, financial condition or results of operations.

If we were to lose any of our significant customers, if our products fail to meet changes in customers’ demands or if we suffer a material reduction in our customers’ purchase orders, our revenue could decline and our operating results and financial condition could be materially and adversely affected. We would have no or limited contractual recourse if our significant customers decided to stop buying and using our products with limited advance notice to us.

AddedRisk Factors
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.

AddedMD&A
In 2025, our Semiconductor Test segment achieved considerable growth driven by robust demand from Artificial Intelligence (“AI”) applications in networking and with vertically integrated producer (“VIP”) compute solutions. Memory test revenue remained stable despite a smaller overall market, supported by share gains in high bandwidth memory (“HBM”) and DRAM final test applications. The Semiconductor Test segment’s strategic shift toward AI-driven semiconductor testing resulted in AI related customer demand driving the majority of our revenue in the second half of 2025. Looking ahead to 2026, we expect AI related customer demand to continue to represent the bulk of our revenues in the first quarter. Our results reflect our focused investments in AI applications and VIP customers, with benefits from these initiatives materializing throughout 2025 and expected to continue in 2026. In the Product Test Group, we also achieved revenue growth in 2025, bolstered primarily by strength in defense and aerospace applications.

AddedMD&A
Goodwill represents the excess of the purchase price in a business combination over the fair value of the net tangible and intangible assets acquired. Goodwill is assessed for impairment at the reporting unit level annually during the fourth quarter of each fiscal year, as of December 31, or more frequently if we believe indicators of impairment exist. Potential impairment is identified by comparing the fair value of a reporting unit to its carrying value, including goodwill. For our annual impairment assessment, we have the option to evaluate qualitative factors such as industry and market conditions, and entity specific financial performance and events, including changes in management, strategy and key customers. If based on our qualitative assessment it is more likely than not that the fair value of the reporting unit is less than its carry amount, we are required to perform quantitative impairment testing. If necessary, an impairment loss is recognized in an amount equal to the excess of the reporting unit’s carrying value over its fair value, up to the amount of goodwill allocated to the reporting unit.

AddedMD&A
Intangible assets acquired through a business combination typically consist of developed technologies, customer relationships, and trademarks and trade names. Long-lived assets primarily consist of property and equipment and operating lease right-of-use assets. We engage third-party valuation specialists to assist us with the initial measurement of the fair value of acquired intangible assets. We evaluate the recoverability of intangible assets and long-lived assets whenever events and changes in circumstances, such as reductions in demand or significant economic slowdowns, indicate that the carrying amount of an asset may not be fully recoverable. When indicators of impairment are present, the future undiscounted cash flows of the related asset group are compared to its carrying value. If necessary, the net book value of the underlying asset is adjusted to fair value as indicated by the sum of the expected discounted cash flows. Fair values are based on estimates of market prices and assumptions concerning the amount and timing of estimated future cash flows.

The impairment assessment of goodwill, intangible assets and long-lived assets involves critical estimates and assumptions, which may be unpredictable and inherently uncertain. These estimates and assumptions may include projected revenue growth rates, projected earnings before interest, taxes, depreciation, and amortization margins, discount rate, and comparable market multiples, specifically revenue multiples. Any changes in key assumptions could impact the result of the impairment assessment.

AddedMD&A
We recognize 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 flow valuations that use information and assumptions provided by management, for example, revenue growth rates, customer attrition rates, and discount rate. We allocate 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 we believe 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.
