Item 1A. Risk Factors

The following are certain risk factors that could affect our business, financial condition and operating results. These risk factors should be considered in connection with evaluating forward-looking statements contained in this Annual Report on Form 10-K or in any other reports filed or furnished by us, because these factors could cause our actual results and financial condition to differ materially from those projected in any such forward-looking statements. Before you invest in us, you should know that making such an investment involves risks, including the risks described below. Although the risks are organized by headings, and each risk is discussed separately, many are interrelated. The risks that are highlighted below are not the only ones that we face. If any of the following risks occur, our business, financial condition and operating results could be negatively affected.

Risks Related to Our Business and Industry

Because we currently derive a substantial portion of our revenues from a small number of customers, any decrease in orders from these customers could have an adverse effect on our business, financial condition and operating results.

We depend on a small number of customers for a substantial portion of our business, and changes in the level of our customers' orders have, in the past, had a significant impact on our results of operations. If a major customer significantly delays, reduces, or cancels the level of business it does with us, there could be an adverse effect on our business, financial condition and operating results. Significant pricing and margin pressures exerted by a major customer could also materially adversely affect our operating results. In addition, we generate significant accounts receivable from sales to our major customers. If one or more of our major customers were to become insolvent or otherwise unable to pay or were to delay payment for our products, our business, financial condition and operating results could be materially adversely affected.

Our customers may cancel their orders, change production quantities or locations or delay production.

We generally receive volume estimates, but not firm volume commitments from our customers, and may experience reduced or extended lead times in customer orders. Customers may cancel orders, change production quantities and delay production for a number of reasons including the use of additional suppliers. Uncertain economic and geopolitical conditions may result in some of our customers delaying the delivery of some of the products we manufacture for them and placing purchase orders for lower volumes of products than previously anticipated. Cancellations, reductions or delays by a significant customer or by a number of customers may harm our results of operations by reducing the volumes of products we manufacture and sell, as well as by causing a delay in the recovery of our expenditures for inventory in preparation for customer orders, or by reducing our asset utilization, resulting in lower profitability.

In addition, our customers may request that manufacturing of their products be transitioned from one of our facilities to another to achieve cost reductions and other objectives. Such transfers may result in short-term inefficiencies and costs due to resulting excess capacity and overhead at one facility and capacity constraints and the inability to fulfill all orders at another. In addition, we make key decisions based on our estimates of customer requirements, including determining the levels of orders that we will seek and accept, production schedules, component procurement commitments, personnel needs and other resource requirements. Changes in demand for our customers’ products may reduce our ability to estimate future customer requirements accurately. This may make it difficult to schedule production and maximize utilization of our manufacturing capacity. Anticipated orders may not materialize, and delivery schedules may be deferred as a result of changes in demand for our products or our customers' products. We often increase staffing and capacity and incur other expenses to meet the anticipated demand of our customers, which causes reductions in our gross margin if customer orders are delayed or canceled. On occasion, customers may require rapid increases in production, which may stress our resources and reduce margins. We may not have sufficient capacity at any given time to meet our customers' demands. In addition, because many of our costs and operating expenses are relatively fixed over the short term, a reduction in customer demand could harm our gross margin and operating income until such time as adjustments can be made to activity and operating levels or to structural costs.

Deterioration of general economic, political, credit and/or capital market conditions could adversely affect our financial performance, our ability to grow or sustain our business, financial condition and results of operations, and our ability to access the capital markets.

We compete around the world in various geographic regions and product markets. Global economic and political conditions affect our business and the businesses of our customers and suppliers. Recessions, economic downturns, price instability, increased tariffs, inflation, slowing economic growth and social and political instability in the markets where we compete could negatively affect our revenues and financial performance, and adversely impact our ability to grow or sustain our business. These uncertainties could impact the expected cash flows to be generated by an asset or group of assets and may result in an impairment of those assets. For example, current macroeconomic and political instability caused by the ongoing conflict between Russia and Ukraine (which we refer to as the "Russia-Ukraine conflict"), global supply chain disruptions and inflation have adversely impacted and could continue to adversely impact our business and financial results.

The capital and credit markets provide us with liquidity to operate and grow our business beyond the liquidity that operating cash flows provide. A global or regional economic downturn or disruption of the credit markets could increase our future borrowing costs and impair our ability to access capital and credit markets necessary for our operations and to execute our strategic plan. If our access to capital on terms commercially acceptable to us were to become significantly constrained, or if costs of capital increased significantly, then our financial condition, results of operations and cash flows could be adversely affected.

Our business, financial condition and results of operations could be adversely affected by disruptions in the global economy caused by the ongoing Russia-Ukraine conflictor other geopolitical tensions and conflict.

The ongoing Russia-Ukraine conflict has adversely affected the global economy, and the geopolitical tensions and conflicts it generates may continue to negatively impact our operations. It has resulted in heightened economic sanctions from the U.S., the U.K., the European Union (the "E.U.") and the international community. Even though we have no physical assets in Russia, the impact of the Russia-Ukraine conflict could have a material adverse effect on our business, financial condition, results of operations, supply chain, availability of critical supplies, intellectual property, partners, or customers. Further escalation of geopolitical tensions related to the Russia-Ukraine conflict, including increased trade barriers or restrictions on global trade, could result in, among other things, broader impacts that expand into other markets, cyberattacks, supply chain and logistics disruptions, and volatility in foreign exchange rates, interest rates and financial markets, any of which may adversely affect our business and supply chain. More broadly, there could be additional negative impacts to our financial results if the Russia-Ukraine conflict worsens, including, among other potential impacts, economic recessions in certain neighboring countries or globally due to inflationary pressures, including with respect to energy and supply chain cost increases or shortages, or the geographic proximity of the conflict relative to the rest of Europe. Similar geopolitical tensions and political and/or armed conflicts, including tensions between the U.S. and China and China and Taiwan could adversely impact our employees, financial performance, and global operations, including by, among other things, jeopardizing the safety of our employees and facilities, disrupting our and our partners’ production, supply chain and logistics and communications, and causing market volatility, which could adversely impact our sales and/or amplify or affect many of our other risks described elsewhere in Part I, Item 1A, "Risk Factors" in this Annual Report on Form 10-K.

The impacts of supply chain constraints, increased tariffs and inflationary pressures could adversely impact our operating results.

Our business has been, and may continue to be, impacted by supply chain constraints, including as a result of raw materials and electronic component shortages, including, in particular, shortages of semiconductor chips and resin, longer lead times, port congestion, increased freight costs and the uncertain economic environment worldwide. These supply chain constraints have and may in the future prevent us from making scheduled shipments to customers. Our inability to make scheduled shipments could cause us to experience a shortfall in revenue, increase our costs and adversely affect our relationship with affected customers and our reputation as a reliable supplier. We may be required to pay higher prices for raw materials or electronic components in short supply and order these raw materials or electronic components in greater quantities to compensate for variable delivery times. We may also be required to pay higher prices for raw materials or electronic components due to increased inflationary trends regardless of supply. In addition, current proposed or future governmental policies (including with respect to tariffs and other trade policies) have increased the risk of inflation, and have (and may continue to) increase the costs of raw materials and other components for our business. The supply and price of our key raw materials and electronic components can be affected by a number of factors beyond our control, including market demand, inflation, alternative sources for suppliers, global geopolitical events, global or regional disease outbreaks or pandemics, trade agreements among producing and consuming nations and governmental regulations.

Similarly, if the cost of goods continue to increase, our suppliers may seek price increases from us. If we are unable to mitigate the impact of these matters through price increases, cost savings to offset cost increases, hedging arrangements, or other measures, our results of operations and financial condition could be adversely impacted. If our competitors maintain or substantially lower their prices, we may lose customers or have to reduce prices. Our profitability may be impacted by prices that do not offset the inflationary pressures, which may impact our gross margin. Even if we are able to raise the prices of our products, we may not be able to sustain such price increases. Temporary or sustained price increases may also lead to a decrease in demand for our products as competitors may not adjust their prices which could lead to a decline in sales volume and loss of market share. Our projections may not accurately predict the volume impact of price increases, which could adversely affect our business, financial condition and results of operations.

Certain materials are primarily available in a limited number of countries, including REEs, minerals, and metals. Trade disputes, geopolitical tensions, economic circumstances, political conditions, or public health issues may limit our ability to obtain such materials. Although these rare earth and other materials are generally available from multiple suppliers, China is a predominant producer of these materials. China has in the past restricted export of certain of these materials and may in the future continue to restrict, expand restrictions, or stop exporting these or other materials, and as a result, our suppliers’ ability to obtain such supply may be constrained, and we may be unable to obtain sufficient quantities, or obtain supply in a timely manner or at a commercially reasonable cost. Constrained supply of REEs, minerals, and metals may restrict our ability to manufacture certain of our products and make it difficult or impossible to compete with other semiconductor memory and storage manufacturers who are able to obtain sufficient quantities of these materials from China.

We sell products to customers in cyclical industries that are subject to significant downturns that could materially adversely affect our business, financial condition and operating results.

We sell products to customers in cyclical industries that have experienced economic and industry downturns. The markets for our products have softened in the past and may soften in the future. We may face reduced end-customer demand, underutilization of our manufacturing capacity, changes in our revenue mix and other factors that could adversely affect our results.

A portion of our revenue is derived from the sale of defense-related products through various contracts and subcontracts. These contracts may be suspended, canceled, or delayed, which could have an adverse impact on our revenues.

We sell products to customers in the aerospace and defense end market. A portion of these customers operate under contracts with the U.S. Government, which are vulnerable to termination at any time, for convenience or default. Some of the reasons for cancellation include, but are not limited to, budgetary constraints or re-appropriation of government funds, timing of contract awards, violations of legal or regulatory requirements, and changes in political agenda. If cancellations were to occur, it would result in a reduction in our revenue. Furthermore, significant reductions to defense spending could occur over the next several years due to government spending cuts, which could have a significant adverse impact on us. Delays in sales of products for defense applications and/or push-outs may adversely impact our results of operations, including quarterly earnings.

We are susceptible to trends and factors affecting industries that we serve.

Factors negatively affecting the industries we serve and the demand for their products could negatively affect our business, financial condition and operating results. Any adverse occurrence, including among others, industry slowdown, recession, public health crisis, political instability, costly or constraining regulations, increased tariffs, reduced government budgets and spending, armed hostilities, terrorism, excessive inflation, prolonged disruptions in one or more of our customers' production schedules or labor disturbances, that results in a decline in the volume of sales in these industries, or in an overall downturn in the business and operations of our customers in these industries, could materially adversely affect our business, financial condition and operating results. These industries may be unionized and some of our customers have experienced labor disruptions in the past. Furthermore, these industries can be highly cyclical in nature and sensitive to changes in general economic conditions, consumer preferences and interest rates. The insolvency of customers that we serve may result in the failure to receive payment in full for products sold in the past and an abrupt reduction in demand for certain products. Weakness in demand, the insolvency of customers that we serve or their suppliers, and constriction of credit markets may negatively and materially affect our facility utilization, cost structure, financial condition, and operating results.

Our operating results may vary significantly from period to period.

We experience fluctuations in our operating results. Some of the principal factors that contribute to these fluctuations are: changes in demand for our products; our effectiveness in managing manufacturing processes, costs and timing of our component purchases so that components are available when needed for production, while mitigating the risks of purchasing inventory in excess of immediate production needs; the degree to which we are able to utilize our available manufacturing capacity; changes in the cost and availability of components, which may occur in the electronics manufacturing industry and which affect our margins and our ability to meet delivery schedules; general economic and served industry conditions; and local conditions and events that may affect our production volumes, such as labor conditions or political instability.

We may pursue acquisition opportunities that are intended to complement or expand our business as well as divestitures that could impact our business operations. We may not be able to complete these transactions, and these transactions, if executed, may pose risks that could materially adversely affect our business, financial condition and operating results.

On an ongoing basis we explore opportunities to buy other businesses or technologies that could complement, enhance or expand our current business or product lines or that might otherwise offer us growth opportunities. For example, over the last few years, we have acquired TEWA Temperature Sensors SP. Zo.o. (“TEWA”), Meggitt A/S (a/k/a Ferroperm Piezoceramics A/S, “Ferroperm”), maglab AG ("Maglab"), and SyQwest, LLC ("SyQwest"). We may have difficulty finding suitable acquisition opportunities or, if we do identify these opportunities, we may not be able to complete the transactions for any number of reasons including a failure to secure financing. In addition, we may not be able to successfully or profitably integrate, operate, maintain and manage newly acquired businesses such as TEWA, Ferroperm, Maglab, and SyQwest including their operations or employees. Any transactions that we are able to identify and complete may involve a number of risks, including: the diversion of management's attention from our existing business to integrate the operations and personnel of the acquired or combined business; possible adverse effects on our operating results during the integration process; difficulties managing and integrating operations in geographically dispersed locations; increases in our expenses and working capital requirements, which could reduce our return on invested capital; exposure to unanticipated liabilities of acquired companies; and our possible inability to achieve the intended objectives of the transaction. Even if we are initially successful in integrating a new operation, we may not be able to maintain uniform standards, controls, procedures and policies, and this may lead to operational inefficiencies. In addition, future acquisitions may result in dilutive issuances of equity securities or the incurrence of additional debt. These and other factors could harm our ability to achieve anticipated levels of profitability from acquired operations or realize other anticipated benefits of an acquisition and could adversely affect our business and operating results.

We have in the past, and may in the future, consider divesting certain business operations. Divestitures may involve a number of risks, including the diversion of management's attention, significant costs and expenses, the loss of customer relationships and cash flow, and the disruption of operations in the affected business. Failure to timely complete or consummate a divestiture may negatively affect valuation of the affected business or result in restructuring charges.

We may restructure our operations or fail to execute capital projects as planned, which may materially adversely affect our business, financial condition and operating results.

We have announced and initiated restructuring plans or capital projects at various times in the past designed to revise and consolidate certain aspects of our operations for the purpose of improving our cost structure and operational efficiency. We may incur restructuring and impairment charges in the future if circumstances warrant, which could be material. Additionally, if we are unsuccessful in implementing restructuring plans or in executing capital projects, we may experience disruptions in our operations and higher ongoing costs, which may materially adversely affect our business, financial condition and operating results.

We have a substantial amount of goodwill on our balance sheet. Future write-offs of goodwill may have the effect of decreasing our earnings or increasing our losses.

We have obtained growth through acquisitions of other companies and businesses. Under existing accounting standards, we are required to periodically review goodwill for possible impairment. In the event that we are required to write down the value of any assets under these pronouncements, it may materially and adversely affect our earnings.

We may be unable to compete effectively against competitors.

The industries in which we operate are highly competitive and characterized by price erosion and technological change. We compete against many domestic and foreign companies, some of which have substantially greater manufacturing, financial, research and development, and marketing resources than we do. If any customer becomes dissatisfied with our prices, quality, or timeliness of delivery, among other things, they could award business to our competitors. Moreover, some of our customers could choose to manufacture and develop particular products themselves rather than purchase them from us. Increased competition could result in price reductions, reduced profit margins and loss of market share, each of which could materially adversely affect our business, financial condition and operating results. These developments also may materially adversely affect our ability to compete successfully going forward. We cannot assure you that our products will continue to compete successfully with our competitors' products.

We may be unable to keep pace with rapid technological changes that could make some of our products or processes obsolete before we realize a return on our investment.

The technologies relating to some of our products have undergone and are continuing to undergo changes. End markets for our products are characterized by technological change, frequent new product introductions and enhancements, changes in customer requirements, and emerging industry standards. The introduction of products embodying new technologies and the emergence of new industry standards could render our existing products obsolete and unmarketable before we can recover any or all of our research, development and commercialization expenses, or our capital investments. Furthermore, the life cycles of our products may change and are difficult to estimate.

We may experience difficulties that could delay or prevent the successful development, introduction and marketing of new products or product enhancements and our new products or product enhancements may not adequately meet the requirements of the marketplace or achieve market acceptance. If we are unable, for technological or other reasons, to develop and market new products or product enhancements in a timely and cost-effective manner, our business, financial condition and operating results could be materially adversely affected.

Products we manufacture may contain design or manufacturing defects that could result in reduced demand for our products or services and liability claims against us.

We maintain high quality control and quality assurance processes. However, defects may occur in the products we manufacture due to design or manufacturing errors, supplier quality issues, or component failure. Product defects could result in delayed shipments and reduced demand for our products. We may be subject to increased costs due to warranty claims on defective products. Product defects could result in product liability claims against us where defects cause, or are alleged to cause, property damage, bodily injury or death. As we grow our business, the risk of exposure to product liability litigation increases. We may be required to participate in a recall involving products which are, or are alleged to be, defective. We carry insurance for certain legal matters involving product liability; however, costs related to product defects and the costs of such claims, including costs of defense and settlement, may exceed our available coverage. Accordingly, our results of operations, cash flow and financial position could be adversely affected.

We are subject to government regulations, including environmental, health, and safety laws and regulations, that expose us to potential financial liability.

Our operations are regulated by a number of federal, state, local and foreign government regulations, including those pertaining to environmental, health, and safety (“EHS”) that govern, among other things, air and water emissions, worker protection, and the handling, storage and disposal of hazardous materials. Compliance with EHS laws and regulations is a major consideration for us because we use hazardous materials in our manufacturing processes. If we are found to be in violation of EHS laws and regulations, we could be liable for substantial fines, penalties, and costs of mandated remedial actions and we could suffer reputational damage due to any such violations. Our environmental permits could also be revoked or modified, which could require us to cease or limit production at one or more of our facilities, thereby materially adversely affecting our business, financial condition and operating results. EHS laws and regulations have generally become more stringent over time and could continue to do so, imposing greater compliance costs and increasing risks and penalties associated with any violation, which also could materially affect our business, financial condition and operating results.

We have been notified by the U.S. Environmental Protection Agency (the “EPA”), state environmental agencies and, in some cases, groups of potentially responsible parties, that we are potentially liable for environmental contamination at several sites currently and formerly owned or operated by us, including sites designated as National Priorities List sites under the EPA’s Superfund program. Superfund liability is joint and several and we may be held responsible for more than our share of contamination at a site. See Note 11, "Commitments and Contingencies," in the Notes to the Consolidated Financial Statements in this Annual Report on Form 10-K. Although we estimate our potential environmental liability and reserve for such matters we cannot assure you that our reserves will be sufficient to cover the actual costs that we incur as a result of these matters.

Future events, such as the notification of potential liability at new sites, the discovery of additional contamination or changes to an approved remedy at an existing site, changes to existing EHS laws and regulations or their interpretation, and more rigorous regulatory action by government authorities, may require additional expenditures by us, which could have a negative impact on our operations.

Changes in tax laws could cause volatility or have a material adverse effect on our business and financial results.

Changes to existing tax laws or the adoption of new tax laws could have a material adverse impact on our effective tax rate, future tax liabilities and the ability to utilize deferred tax assets. The current economic and political environment may result in significant tax law changes in the numerous jurisdictions in which we operate. In addition, our effective tax rate could be materially affected by certain tax proposals developed by the Organization for Economic Cooperation and Development and European Commission regarding the taxation of multinational businesses. Adverse changes in the underlying profitability and financial outlook of our operations in several jurisdictions could lead to changes in our valuation allowances against deferred tax assets and other tax accruals that could materially and adversely affect our results of operations. In addition, acquisitions or divestitures may cause our effective tax rate to change.

We base our tax positions upon the anticipated nature and conduct of our business and upon our understanding of the tax laws of the various countries in which we have assets or conduct activities. However, our tax positions are subject to review and possible challenge by taxing authorities and to possible changes in law, which may have a retroactive effect.

Continued economic and political pressures to increase tax revenues in jurisdictions in which we operate, or the adoption of new or reformed tax legislation or regulation, may make resolving tax disputes more difficult. The final resolution of tax audits and any related litigation can differ from our historical provisions and accruals, resulting in an adverse effect on our financial performance.

Failure to comply with existing laws and regulations or changes in these laws, regulations, or interpretations thereof, specifically tax laws could result in the loss, revocation or suspension of our licenses, permits or approvals and could have a material adverse effect on our business, financial condition and results of operations. Additionally, uncertainties exist with respect to the interpretation of, and potential future developments in, complex domestic and international tax laws and regulations, the amount and timing of future taxable income and the interaction of such laws and regulations among jurisdictions. Given the wide range of international business relationships and the long-term nature and complexity of existing contractual agreements, differences arising between the actual results and assumptions made, or future changes to such assumptions, could necessitate future adjustments to tax income and expense already recorded.

Uncertainty over global tariffs and trade policies, or the financial impact of tariffs and trade policies, may negatively affect our results.

Protectionist trade legislation in the United States, the E.U., the U.K., Canada, China or Mexico, such as new or increased tariffs structures, export or import compliance laws, or other trade policies could adversely affect our supply chain, business and results of operations. Similarly, further changes to United States and foreign trade and tax policies, including heightened import restrictions, import and export licenses, new or increased tariffs, trade embargoes, government sanctions, and trade barriers could have a similar impact. Increased tariffs could require us to increase our prices, which could decrease demand for our products. In addition, other countries may limit their trade with the United States or retaliate through their own restrictions and/or new or increased tariffs, which could affect our ability to export products and therefore adversely affect our sales. Many of these challenges, particularly tariffs, are present, or may arise in commerce with the E.U., China, and Mexico markets in which we operate and with which we do business. While we believe we have taken steps to mitigate their potential effects, our mitigation activities may prove to be ineffective or detrimental to our business. There exists substantial uncertainty as to whether such tariffs will be fully implemented or sustained. There can be no assurances that such tariffs will not be implemented or increased in the future, with the previously mentioned countries or additional countries with which we do business. The degree to which these changes in U.S. tariff structures or other trade policy affect our business and results of operations will be influenced by the specific details of the changes in tariffs or other trade policies, their timing and duration, and our effectiveness in deploying tools and strategies to address these issues.

During 2025, there were significant changes to tariffs by the U.S. and other countries. The tariff modifications are at various rates, with exemptions applicable to some categories of imports and exports. While we are attempting to mitigate tariff-related impacts with a focus on agility in adapting to cost and price adjustments, there can be no assurance our mitigation efforts will be successful. The Company’s management continues to monitor and evaluate the ongoing situation, with plans formulated to respond to a varied range of potential market scenarios. Additional tariffs or future changes to the U.S.’s or other countries’ trade relations could further impact our business and negatively affect our results of operations.

Risks Related to Technology, Cybersecurity and Data Privacy

We are exposed to, and may be adversely affected by, cybersecurity threats, incidents or other disruptions to our information technology systems and data.

We rely on information technology systems and networks, including cloud-based systems, in connection with many of our business activities, some of which are managed directly by us, while others are managed by third-party service providers and are not under our direct control. Our operations routinely involve receiving, storing, processing and transmitting information pertaining to our business, customers, suppliers, employees, and other operations. We have both an increasing reliance on information technology systems and an increasing digital footprint as a result of changing technologies, connected devices and digital offerings, as well as remote work policies. If these technologies, systems, products or services are threatened, disputed, damaged, cease to function properly, are compromised due to employee or third-party contractor error, user error, malfeasance, system errors, or other vulnerabilities, technology malfunction, or as the result of events or circumstances of broader geographic impact (e.g., earthquake, storm, flood, epidemic, strike, act of war, civil unrest or terrorist act), or are subject to cybersecurity incidents, such as those involving denial-of-service attacks, ransomware, phishing or social engineering, unauthorized access, malicious software, or other intrusions or disruptions, including by criminals, nation states or insiders, our business may be adversely impacted. The impacts of any such circumstances could include production downtimes, operational delays, and other impacts on our operations and ability to provide products and services to our customers; compromise of confidential, proprietary or otherwise protected information, including personal information and customer confidential data; destruction, corruption, or theft of data or intellectual property; manipulation, disruption, or improper use of these technologies, systems, products or services; financial losses from fraudulent transactions, remedial actions, loss of business or potential liability; adverse media coverage or publicity; legal claims or legal proceedings, including class action and commercial litigation, ransom payments, regulatory investigations, actions and fines; and damage to our reputation and, as a result, have a material adverse effect on our business operations and financial performance.

Cybersecurity incidents could have a disruptive effect on our business.

From time to time, we and the service providers or other business partners that we depend on to host our data and support or provide our systems and business operations, are the target of, and periodically respond to, cybersecurity threats, including phishing and denial-of-service attacks, which, if successful, could result in a loss of business or customer information, systems interruption or the disruption of our operations, among other things. The techniques that are used to obtain unauthorized access, disable or degrade service or sabotage systems and data change frequently, have continued to increase in recent years and such efforts may be difficult to detect for long periods of time. As a result, we monitor our systems to protect our technology infrastructure and data. In addition, we further attempt to mitigate these risks by employing a number of other measures, including employee training, an incident response plan, and maintenance of backup and protective systems. Further, while we maintain insurance coverage that is intended to address certain aspects of cybersecurity risks, such insurance coverage may not cover all losses or all types of claims that arise. Notwithstanding these measures, our systems, networks, products and services remain potentially vulnerable to known or unknown cybersecurity threats, any of which could have a material adverse effect on our business operations and financial performance. We have in the past been subject to cybersecurity events and incidents of varying degrees and expect that we will be subject to additional cybersecurity events and incidents in the future. To date however, none of the incidents or events have had a material impact on us.

We are exposed to risks and costs associated with complying with privacy laws and protecting personal data and other sensitive information.

We are subject to various risks and costs associated with the collection, handling, storage and transmission of information, including costs related to compliance with U.S. and foreign data protection and privacy laws and other contractual obligations, as well as risks associated with the compromise of our systems collecting such information. Many jurisdictions, including the E.U., the U.K., China and certain states within the U.S., have passed laws that require companies to meet specific requirements regarding the processing, use, and disclosure of personal data and giving individuals certain rights over their personal data. We collect internal and customer data and other information, including personal data for a variety of business purposes, including managing our workforce and providing requested products and services. We could be exposed to investigations and regulatory actions, fines, penalties, restrictions, individual, class action, and commercial litigation, reputational harm or other expenses, or other adverse effects on our business, due to failure to protect personal data or other sensitive information or failure to maintain compliance with the various U.S. and foreign data collection and privacy laws or applicable data security standards.

Failure to keep pace with developments in technology could adversely affect our operations or competitive position and we may be exposed to risks and incur costs associated with maintaining or upgrading our technology and systems.

The technologies and systems we use to operate our business may require refinements and upgrades, and third parties may cease support of systems that are currently in use. The development and maintenance of these technologies may require significant investment by us. As various systems and technologies become outdated or new technology is required, we may not be able to replace or introduce them as quickly as needed or in a cost-effective manner. As a result, our business operations could be disrupted and we could be exposed to cybersecurity threats, adversely affecting our business operations and financial performance.

Because third parties provide us with a number of operational and technical services, third-party cybersecurity incidents could expose us to liability, harm our reputation, damage our competitiveness and adversely affect our financial performance.

Third parties provide us with certain operational and technical services. These third parties may have access to our systems, provide hosting services or other services to support our business, or otherwise process data about or on behalf of us, our employees or partners. Any cybersecurity incident impacting a third party business partner or service provider could compromise the security, integrity or availability of systems or data, or result in the theft, unauthorized access or processing, or disruption of access to data, which could negatively impact our operations. We rely on the internal processes and controls of third-party software, systems, and application vendors to maintain the security of all software code, systems, and data provided to or used by or on behalf of the Company. Any cybersecurity incidents involving third parties on which we rely could negatively affect our reputation, our competitive position and our financial performance, and we could face regulatory scrutiny, investigations, lawsuits and further potential liability.

As we integrate artificial intelligence technologies into our processes, these technologies may present business, compliance and reputational risks.

Recent technological advances in artificial intelligence (“AI”) and machine-learning technology present new opportunities and also pose new risks. Our introduction of these technologies into our internal processes may result in new or expanded risks and liabilities. Such risks and liabilities include enhanced governmental or regulatory scrutiny, litigation, compliance issues, ethical concerns, confidentiality or security risks, as well as other factors that could adversely affect our business, reputation, and financial results. The utilization of AI could also result in loss of intellectual property and subject us to heightened risks related to intellectual property infringement or misappropriation. The use of AI can lead to unintended consequences, including generating content that is inaccurate, misleading or otherwise flawed, or that results in unintended biases and discriminatory outcomes, which could harm our reputation and expose us to risks related to inaccuracies or errors in the output of such technologies. Additionally, to the extent our competitors successfully adopt AI and experience enhanced efficiencies and/or reduced costs, we may be at a competitive disadvantage that could adversely impact our business operations or financial performance.

Risks Related to Indebtedness and Financing

Our indebtedness may adversely affect our financial health.

Our indebtedness could, among other things: increase our vulnerability to general economic and industry conditions, including recessions; require us to use cash flow from operations to service our indebtedness, thereby reducing our ability to fund working capital, capital expenditures, research and development efforts and other expenses; limit our flexibility in planning for, or reacting to, changes in our business and the industries in which we operate; place us at a competitive disadvantage compared to competitors that have less indebtedness; or limit our ability to borrow additional funds that may be needed to operate and expand our business.

Our revolving credit facility contains restrictions limiting our ability to: dispose of assets; incur certain additional debt; repay other debt or amend subordinated debt instruments; create liens on assets; make investments, loans or advances; make acquisitions or engage in mergers or consolidations; engage in certain transactions with our subsidiaries and affiliates; repurchase stock; or make dividend payments above a certain amount.

The restrictions contained in our credit facility could limit our ability to plan for or react to changes in market conditions or meet capital needs or could otherwise restrict our activities or business plans. These restrictions could adversely affect our ability to finance our operations, make strategic acquisitions, fund investments or other capital needs or engage in other business activities that could be in our interest.

Further, our ability to comply with our loan covenants may be affected by events beyond our control that could result in an event of default under our credit facility, or documents governing any other existing or future indebtedness. A default, if not cured or waived, may permit acceleration of our indebtedness. In addition, our lenders could terminate their commitments to make further extensions of credit under our credit facility. If our indebtedness is accelerated, we cannot be certain that we will have sufficient funds to pay the accelerated indebtedness or that we will have the ability to refinance accelerated indebtedness on terms favorable to us, or at all.

The estimates and assumptions on which our financial projections are based may prove to be inaccurate, which may cause our actual results to materially differ from such projections, which may adversely affect our future profitability, cash flows and stock price.

Our financial projections, including any sales or earnings guidance or outlook we may provide from time to time, are dependent on certain estimates and assumptions related to, among other things, development and launch of innovative new products, market share projections, product pricing, sales, volume and product mix, foreign exchange rates and volatility, tax rates, interest rates, commodity prices, cost savings, accruals for estimated liabilities, including litigation reserves, and our ability to generate sufficient cash flow to reinvest in our existing business, fund internal growth, repurchase our stock, make acquisitions, pay dividends and meet debt obligations. There is no assurance that we will fully realize the anticipated cost savings and other benefits of our restructuring activities in the time frames we desire or at all. Our financial projections are based on historical experience and on various other estimates and assumptions that we believe to be reasonable under the circumstances and at the time they are made, and our actual results may differ materially from our financial projections. Any material variation between our financial projections and our actual results may adversely affect our future profitability, cash flows and stock price.

Risks Related to Other External Factors

Loss, operational disruptions or closure of a key facility, including those of our suppliers, due to unforeseen or catastrophic events or otherwise, could have a material adverse effect on our business and financial results.

Our business could be interrupted and our financial results could be materially adversely impacted by physical risks such as earthquakes, fires, hurricanes, floods, acts of war, terrorist attacks, cyberattacks and other disruptions in information systems, disease outbreaks or pandemics, and other natural disasters or catastrophic events that damage, disrupt or destroy one of our key facilities or the key facilities of our significant suppliers. If any of our key facilities or the key facilities of our significant suppliers experience a significant operational disruption or catastrophic loss, it could delay, disrupt or reduce production, shipments and revenue, and result in potentially significant expenses to repair or replace these properties. Such significant disruptions could be due to, among other things:

the loss or disruption of the timely availability of adequate supplies of essential raw materials for us and our suppliers, including single-source suppliers;

our ability to integrate new suppliers into our operations;

material financial issues facing our suppliers, such as bankruptcy or similar proceedings;

transportation and logistics challenges, including as a result of port and border closures and other governmental restrictions and the availability and capacity of shipping channels;

the loss or disruption of other manufacturing, distribution and supply capabilities;

the loss or disruption of the energy sources or energy suppliers in Europe due to supply shortages as a result of the Russia-Ukraine conflict, including price increases in the energy market;

labor shortages, strikes or work stoppages;

illness to our employees or their families or governmental restrictions on such employees' ability to travel or perform necessary business functions; or

as a result of the need for us or our suppliers to operate our respective businesses with substantial modifications to employee travel and employee work locations.

Additionally, certain catastrophes are not covered by our general insurance policies, which could result in significant unrecoverable losses. Our business and results of operations could also be adversely impacted by under-investment in physical assets or production capacity.

Climate-related events and climate change legislation could adversely impact our business.

The effects of climate change and the ongoing efforts to mitigate its impact, including through climate change-related legislation and regulation, could have a material adverse effect on our business, financial condition, and results of operations. The physical effects of climate change, including extreme weather and natural disasters (including those risks discussed under the heading “Loss, operational disruptions or closure of a key facility, including those of our suppliers, due to unforeseen or catastrophic events or otherwise, could have a material adverse effect on our business and financial results”) may disrupt our operations and those of our customers and suppliers. In addition, changes to laws or regulations enacted to address the potential impacts of climate change could have a material adverse impact on our business, financial condition, and results of operations. For example, continuing political and social attention to the issue of climate change has resulted in both existing and pending international agreements and national, regional, or local legislation and regulatory measures to limit greenhouse gas emissions. Any future increased regulation concerning greenhouse gas emissions and other climate-change related laws and regulations, may require equipment modifications, operational changes, payment of increased or additional taxes, or the purchase of emission credits to reduce the emission of greenhouse gases from our operations, which may result in us incurring substantial capital expenditures and compliance, operating, maintenance and remediation costs. In addition, any such future regulatory changes could result in transition risks to our business, including but not limited to (i) the nature and timing of any requirement to lower greenhouse gas emissions and adopt more energy-efficient energy use, which could result in changes or disruptions to the way we operate our business, (ii) the risk of lower demand for our products related to customers who experience business declines or disruptions due to the impact of any requirement to lower greenhouse gas emissions, (iii) financial risks where compliance with such regulations requires unforeseen capital expenditures, (iv) legal risks associated with the implementation of any new technologies required to comply with such regulations, which could impede our ability to innovate new products, meet customer and market demand or compete on pricing and quality in the market, and/or (v) reputational risks associated with our customers’ and investors’ perceptions of our business. We are not able to predict how any future definitive agreements, pacts and/or regulations, if and when they are adopted and required, and the commitments necessary to comply with such requirements, will affect our business, financial condition, and results of operations.

General Risk Factors

Unfavorable outcomes of legal or regulatory matters may adversely affect our business and financial condition and damage our reputation.

We are from time to time involved in or subject to a variety of litigation, claims, legal or regulatory proceedings or matters related to our business, warranty claims, our intellectual property rights, alleged infringement or misappropriation by us of intellectual property rights of others, tax, environmental, privacy, insurance, ERISA and employment matters. Such matters, even those that are ultimately non-meritorious, can be complex, costly, and highly disruptive to our business operations by diverting the attention and energies of management and other key personnel, and may generate adverse publicity that damages our reputation. The assessment of the outcome of such matters, including our potential liability, if any, is a highly subjective process that requires judgments about future events that are not within our control and are based on the information available to management at that time. The outcome of such matters, including amounts ultimately received or paid upon judgment or settlement, may differ materially from management’s outlook or estimates, including any amounts accrued in the financial statements. Actual outcomes, including judgments, awards, settlements or orders, could have a material adverse effect on our business, financial condition, operating results, or cash flows and damage our reputation.

We face risks relating to our international operations.

Because we have significant international operations, our operating results and financial condition could be materially adversely affected by economic, political, health, regulatory and other factors existing in foreign countries in which we operate. Our international operations are subject to inherent risks, which may materially adversely affect us, including: political and economic instability in countries in which our products are manufactured; expropriation or the imposition of government controls; changes in government regulations; export license requirements; trade restrictions and tariffs; earnings repatriation and expatriation restrictions; exposure to different legal standards, including related to intellectual property; health conditions and standards; currency controls; fluctuations in exchange rates; increases in the duties and taxes we pay; inflation or deflation; greater difficulty in collecting accounts receivable and longer payment cycles; changes in labor conditions and difficulties in staffing and managing our international operations; limitations on insurance coverage against geopolitical risks, natural disasters, and business operations; and communication among and with management of international operations. In addition, these same factors may also place us at a competitive disadvantage compared to some of our foreign competitors.

CTS CORPORATION19

Table of Contents

We may face risks associated with violations of the Foreign Corrupt Practices Act and similar anti-bribery laws (collectively, "Anti-Bribery Laws"). Anti-Bribery Laws generally prohibit companies and their intermediaries from making improper payments to government officials for the purpose of obtaining or retaining business. Our Code of Ethics mandates compliance with these Anti-Bribery Laws. We operate in many parts of the world where strict compliance with Anti-Bribery Laws may conflict with local customs and practices. We cannot assure you that our internal controls and procedures always will protect us from detrimental actions by our employees or agents. If we are found to be liable for violations of Anti-Bribery Laws (either due to our own acts or inadvertence or due to the acts or inadvertence of others), we could be subjected to criminal or civil penalties or other sanctions, which could have a material adverse effect on our business.

Public health or safety concerns and governmental restrictions that impact the availability of raw materials, labor, or the movement of goods in some of the countries in which we operate could have a material adverse effect on our business, financial condition, and operating results.

We are exposed to fluctuations in foreign currency exchange rates that may adversely affect our business, financial condition and operating results.

We transact business in various foreign countries. We present our consolidated financial statements in U.S. dollars, but a portion of our revenues and expenditures are transacted in other currencies. As a result, we are exposed to fluctuations in foreign currencies. Additionally, we have currency exposure arising from funds held in local currencies in foreign countries. Volatility in the exchange rates between the foreign currencies and the U.S. dollar could harm our business, financial condition and operating results. Furthermore, to the extent we sell our products in foreign markets, currency fluctuations may result in our products becoming too expensive for foreign customers.

If we are unable to protect our intellectual property or we infringe or are alleged to infringe, on others' intellectual property rights, our business, financial condition and operating results could be materially adversely affected.

The success of our business depends, in part, upon our ability to protect our trade secrets, trademarks, copyrights and patents, obtain or license patents and operate without infringing on the intellectual property rights of others. We rely on a combination of trade secrets, copyrights, patents, nondisclosure agreements and technical and other measures to protect our proprietary rights in our products and technology. The steps we have taken to prevent misappropriation of our technology may be inadequate. In addition, the laws of some foreign countries in which we operate do not protect our proprietary rights to the same extent as do the laws of the United States. Although we continue to evaluate and implement protective measures, there can be no assurance that these efforts will be successful. Our inability to protect our intellectual property rights could diminish or eliminate the competitive advantages that we derive from our technology, cause us to lose sales or otherwise harm our business.

We believe that patents will continue to play an important role in our business. However, there can be no assurance that we will be successful in securing patents for claims in any pending patent application or that any issued patent will provide us with any competitive advantage. We also cannot provide assurance that the patents will not be challenged by third parties or that the patents of others will not materially adversely affect our ability to do business.

We may become involved in litigation in the future to protect our intellectual property or because others may allege that we infringed on their intellectual property. These claims and any resulting lawsuit could subject us to liability for damages and invalidate our intellectual property rights. If an infringement claim is successfully asserted by a holder of intellectual property rights, we may be required to cease marketing or selling certain products, pay penalties and spend significant time and money to develop a non-infringing product or process or to obtain licenses for the technology, process or information from the holder. We may not be successful in the development of a non-infringing alternative, or licenses may not be available on commercially acceptable terms, if at all, in which case we may lose sales and profits. In addition, any litigation could be lengthy and costly and could materially adversely affect us even if we are successful in the litigation.

Loss of our key management and other personnel, or an inability to attract key management and other personnel, could materially affect our business.

We depend on our senior executive officers and other key personnel to run our business. We do not have long-term employment contracts with our key personnel. The loss of any of these officers or other key personnel could adversely affect our operations. Our future success depends on our ability to identify, attract, and retain qualified personnel on a timely basis. If we were to experience turnover of senior management or if a member of our senior management were to become ill or incapacitated, our stock price, our results of operations, our commercial and supply chain operations and our vendor or customer relationships could each be adversely impacted, and such events may make recruiting for future management positions more difficult. The labor market for many of our employees is very competitive, and wages and compensation costs continue to increase. Our ability to attract and retain key talent has been, and may continue to be, impacted by challenges in the labor market, particularly in the U.S., which has recently been experiencing wage inflation, labor shortages, and the impacts of remote work. If we face labor shortages and/or increased labor costs as a result of increased competition for employees, higher employee turnover rates, or increases in employee benefits costs, our operating expenses could increase, which could negatively impact our growth and results of operations. Labor shortages, and higher employee turnover rates could also lead to disruptions in our business. In addition, we must successfully integrate any new management personnel that we hire within our organization, or who join our organization as a result of an acquisition, in order to achieve our operating objectives, and changes in other key management positions may temporarily affect our financial performance and results of operations as new management becomes familiar with our business.

Ineffective internal control over our financial reporting may harm our business.

We are subject to the ongoing internal control provisions of Section 404 of the Sarbanes-Oxley Act of 2002 ("Sarbanes-Oxley"). Our controls necessary for continued compliance with Sarbanes-Oxley may not operate effectively or at all times and may result in a material weakness. The identification of material weaknesses in internal control over financial reporting could indicate a lack of proper controls to generate accurate financial statements. Further, the effectiveness of our internal controls may be impacted if we are unable to retain sufficient skilled finance and accounting personnel, especially in light of the increased demand for such personnel among publicly traded companies.

Shareholder activism efforts or unsolicited offers from a third party could cause a material disruption to our business and financial results.

We may be subject to various legal and business challenges due to actions instituted by shareholder activists or an unsolicited third-party offer. Perceived uncertainties as to our future direction as a result of shareholder activism may lead to the perception of a change in the direction of the business or other instability and may affect our relationships with vendors, customers, prospective and current employees and others. Proposed or future laws and regulations may increase the chance we become the target of shareholder activist campaigns, including environmental, social, and governance-related actions. If shareholder activist campaigns are initiated against us, our response to such actions could be costly and time-consuming, which could divert the attention and resources of our Board of Directors, Chief Executive Officer and senior management from the pursuit of our business strategies, which could harm our business, negatively impact our stock price, and have an adverse effect on our business and financial results.

Future dividends on our common stock may be restricted or eliminated.

Dividends are declared at the discretion of our Board of Directors, and future dividends will depend on our future earnings, cash flow, financial requirements and other factors. Under the most restrictive terms of our credit agreements, our ability to pay cash dividends on our common stock is limited, as described under “Risks Related to Indebtedness and Financing.” There can be no assurance that we will continue to pay dividends in the future.

CTS CORPORATION21

Table of Contents

We may not continue to repurchase our common stock or make repurchases of our common stock at favorable prices.

In November 2025, our Board of Directors approved a new share repurchase program authorizing the Company to repurchase up to $100 million of its common stock. This program replaces the prior share repurchase program that was approved in February 2024. The program has no set expiration date and allows for repurchases from time to time in the open market or through privately negotiated transactions. The timing and actual amount of share repurchases, if any, will depend on a number of factors, including our evaluation of general market and economic conditions, our financial condition and the trading price of our common stock. The repurchase program may be extended, modified, suspended or discontinued at any time. A reduction in, or the completion of, our repurchase program could have a negative effect on our stock price. We can provide no assurance that we will repurchase our common stock at favorable prices, or at all.

On August 16, 2022, the Inflation Reduction Act of 2022 (“Inflation Reduction Act”) was enacted. The Inflation Reduction Act imposes on publicly-traded companies a new, nondeductible excise tax equal to 1% of the fair market value of any stock of a company that is repurchased after December 31, 2022, during its taxable year. Because this excise tax would be payable by us, and not by a redeeming holder, the imposition of this excise tax could cause a reduction in the cash available on hand to implement the repurchase program.

Item 1C. Cybersecurity

Risk Management and Strategy

The Company’s cybersecurity risk management strategy is comprised of several key elements. We assess our information technology and data management/storage systems and related policies and practices to help guide and prioritize our cybersecurity and information technology-related investments, activities and risk management strategy. We leverage a variety of technologies to attempt to mitigate the risk of cybersecurity threats and incidents. The Company has a multi-layer approach to its technology solutions, including employing applications used for perimeter, network, end point and application security as well as for data recovery, in each case tailored to the Company’s systems, data, risk profile and mitigation strategy. From time to time, we use third-party service providers and software to augment and test our technology solutions and further support our risk mitigation strategy.Further, the Company maintains processes to oversee and identify material risks from cybersecurity threats associated with its use of third-party service providers.

CTS uses a managed security services provider (MSSP) and other technologies to collect alerts and security audit logs, monitor and assess cybersecurity threat intelligence, and take actions to help us prevent, detect, mitigate and remediate cybersecurity incidents.

We have a cybersecurity training program that covers a variety of topics designed to educate our employees about the importance of cybersecurity awareness, highlight typical cybersecurity-related risks and issues (such as phishing attacks and other methods used to attempt to infiltrate our systems) and test that awareness using knowledge assessments and simulations. The training is administered to employees on a rolling basis, and we use a third-party provider for the content and periodically update the training to incorporate new cybersecurity-related developments.

The oversight of our cybersecurity risk is integrated into our enterprise-wide risk management process. We annually review cybersecurity risk as part of our enterprise risk management process and evaluate whether to integrate those findings into our overall cybersecurity strategy. We have a Cybersecurity Strategy Committee, which is a cross-functional team of business representatives led by our Vice President of IT, which is responsible for spearheading the ongoing development and execution of our cybersecurity strategy. The Cybersecurity Strategy Committee meets regularly and at other times as needed, and periodically updates the Company’s management on its progress and activities.

Like many other companies, from time to time, we detect attempts by third parties to gain access to our systems and networks, and the frequency of such attempts could increase in the future. We have in the past been subject to cybersecurity incidents which have not had a material impact on our business or financial condition and expect that we will be subject to additional cybersecurity incidents in the future. As of the date of this Annual Report on Form 10-K, we are not aware of any cybersecurity threats, including as a result of previous cybersecurity incidents, that have materially affected or are reasonably likely to materially affect the Company, including its business strategy, results of operations or financial condition. However, there can be no assurance that our efforts to prevent or mitigate cybersecurity incidents will be successful. Please see “Risks Related to Technology and Data Privacy” in “Risk Factors” in Section 1A of this Annual Report on Form 10-K.

Governance

Our cybersecurity program is overseen by our Vice President of IT, who has over 20 years of experience working in various information technology roles.Our Vice President of IT is supported by a team of enterprise information system and security risk professionals (collectively, the “IT Team”), who are responsible for identifying, assessing, monitoring, managing and communicating the Company’s cybersecurity risks.The IT Team includes a cybersecurity director with over 20 years of experience in IT infrastructure, IT operations and cybersecurity, and members who hold Certified Information Systems Security Professional (CISSP) and Certified Information Security Manager (CISM) certifications and have experience developing and implementing enterprise-wide cybersecurity strategies and initiatives, managing risks relating thereto, and evaluating industry standards and regulations.

While our Board has the ultimate oversight responsibility for the risk management process, the Audit Committee is responsible for oversight of our cybersecurity strategy and risks. The Vice President of IT and other members of management provide the Audit Committee with quarterly and as needed updates on the Company’s cybersecurity strategy and risks. In addition, the Board is provided with an annual cybersecurity update that addresses similar topics to those discussed with the Audit Committee on a quarterly basis.

In the event of a reported potential cybersecurity incident, our IT Team decides whether such an incident triggers our Cybersecurity Threat Evaluation and Response Plan (the “Response Plan”). If triggered, the Company’s cybersecurity response team, as needed under the circumstances (the “Cyber Response Team”), is convened. Members of the Cyber Response Team, as appropriate and as set forth in the Response Plan, are responsible for developing, recommending and implementing measures to address the cybersecurity incident, including when appropriate, assessing, containing and mitigating its impact, notifying members of the Company’s management, the Audit Committee and the full Board of the cybersecurity incident, and coordinating external communications, in each case as appropriate under the circumstances. The IT Team is responsible for implementing and monitoring the effectiveness of any remediation plan adopted as a result of a cybersecurity incident.

Item 3. Legal Proceedings

From time to time we are involved in litigation with respect to matters arising from the ordinary conduct of our business, and currently certain claims are pending against us. In the opinion of management, we believe we have established adequate accruals pursuant to U.S. generally accepted accounting principles for our expected future liability with respect to pending lawsuits, claims and proceedings, where the nature and extent of any such liability can be reasonably estimated based on presently available information. However, we cannot provide assurance that the final resolution of any existing or future lawsuits, claims or proceedings will not have a material adverse effect on our business, results of operations, financial condition, or cash flows.

Overview

CTS Corporation ("CTS", "we", "our" or "us") is a leading designer and manufacturer of products that Sense, Connect and Move. Our vision is to be a leading provider of sensing and motion devices as well as connectivity components, enabling an intelligent and seamless world. These devices are categorized by their ability to Sense, Connect or Move. Sense products provide vital inputs to electronic systems. Connect products allow systems to function in synchronization with other systems. Move products ensure required movements are effectively and accurately executed. We are committed to achieving our vision by continuing to invest in the development of products, technologies and talent within these categories.

We manufacture sensors, actuators and connectivity components in North America, Europe, and Asia. CTS provides highly engineered products to OEMs and tier one suppliers in the aerospace and defense, industrial, medical, and transportation markets, and the U.S. Government.

There is an increasing proliferation of sensing and motion applications within various markets we serve. In addition, the increasing connectivity of various devices to the internet results in greater demand for communication bandwidth and data storage, increasing the need for our connectivity products. Our success is dependent on the ability to execute our strategy to support these trends. We are subject to challenges including periodic market softness, competition from other suppliers, changes in technology, and the ability to add new customers, launch new products or penetrate new markets.

Results of Operations: Year Ended December 31, 2025 versus Year Ended December 31, 2024

(Amounts in thousands, except percentages and per share amounts):

The following table highlights changes in significant components of the Consolidated Statements of Earnings for the years ended December 31, 2025, and December 31, 2024:

Years Ended December 31, Percent of Net Sales

Diluted earnings per share:

Diluted net earnings per share $ 2.19 $ 1.81

Net sales were $541,318 for the year ended December 31, 2025, an increase of $26,562, or 5.2%, from 2024. Net sales to the diversified end markets increased $42,998, or 16.3%. We achieved growth in the aerospace & defense and medical end markets and saw continued recovery in the industrial end market. The acquisition of SyQwest, LLC ("SyQwest") added net sales of $22,329 and $13,433 in 2025 and 2024, respectively. Net sales to the transportation end market decreased $16,436 or 6.6%, primarily driven by lower volumes of our commercial vehicle related products and our customers' loss of market share in China.

Gross margin was $208,026 for the year ended December 31, 2025, an increase of $20,471, or 10.9%, from the year ended December 31, 2024. The increase in gross margin was primarily driven by continued operational improvements and an improved mix of sales by end market.

Selling, general and administrative ("SG&A") expenses were $98,720, or 18.2% of sales for the year ended December 31, 2025, versus $88,285 or 17.2% of sales in 2024. The increase in SG&A expenses was primarily driven by higher amortization expense in 2025 from the SyQwest acquisition and a one-time charge related to the potential settlement of prior period costs with the U.S. Environmental Protection Agency (the "EPA").

Research and development expenses were $25,268, or 4.7% of sales in 2025, compared to $23,388, or 4.5% of sales in 2024. We continue to invest in research and product development to drive long-term organic growth.

Restructuring charges were $1,396, or 0.3% of net sales in 2025, compared to $4,697, or 0.9% of net sales in 2024. The restructuring charges in the year ended December 31, 2025 were primarily related to changes to adjust our business in response to demand changes across certain locations and products. See Note 9, “Costs Associated with Exit and Restructuring Activities,” in the Notes to the Consolidated Financial Statements in this Annual Report on Form 10-K for further information.

Other income and expense items are summarized in the following table:

Years Ended December 31,

Other income (expense), net 3,304 (2,650 )

Total other income (expense), net $ 1,129 $ (2,604 )

Interest income decreased due to lower investments of available cash as a result of the SyQwest acquisition. Other income for 2025 is driven by foreign currency translation gains primarily related to the Euro and Mexican Peso, and a prior period adjustment recorded related to the SyQwest acquisition. See Note 1 “Summary of Significant Accounting Policies” in the Notes to the Condensed Consolidated Financial Statements in this Annual Report on Form 10-K for further information.

Years Ended December 31,

The effective income tax rate in 2025 was 22.0% compared to 18.4% in the prior year. The increase in the effective income tax rate is primarily attributable to a change in mix of earnings taxed at higher rates and the impact of the One Big Beautiful Bill Act (the "OBBBA"). See Note 19 “Income Taxes” in the Notes to the Condensed Consolidated Financial Statements in this Annual Report on Form 10-K for further information.

Liquidity and Capital Resources

We have historically funded our capital and operating needs primarily through cash flows from operating activities, supported by available credit under our Revolving Credit Facility (as defined below). We believe that cash flows from operating activities and available borrowings under our Revolving Credit Facility will be adequate to fund our working capital needs, capital expenditures, investments, and debt service requirements for at least the next twelve months and for the foreseeable future thereafter. However, we may choose to pursue additional equity and debt financing to provide additional liquidity or to fund acquisitions.

Cash and cash equivalents were $82,295 at December 31, 2025 and $94,334 at December 31, 2024, of which $75,943 and $92,944, respectively, were held in our foreign affiliates. Total debt as of December 31, 2025 and December 31, 2024 was $57,500 and $92,300, respectively.

Cash Flows from Operating Activities

Net cash provided by operating activities was $102,105 during the year ended December 31, 2025. Components of net cash provided by operating activities included net earnings of $65,317, depreciation and amortization expense of $34,538, other net non-cash items totaling $750, and a net cash inflow from changes in assets and liabilities of $3,694 primarily driven by increases in accrued expenses and other liabilities, accounts payable and accrued payroll partially offset by an increase in accounts receivable.

Capital Resources

Long-term debt was comprised of the following:

As of December 31,

Amount available, subject to covenant restrictions $ 240,860 $ 306,060

Weighted-average interest rate 5.48 % 6.41 %

On November 24, 2025, we entered into a new five-year revolving credit agreement (the “Revolving Credit Facility”) with a group of banks for a total credit facility availability of $300,000 which may be increased by up to $125,000, subject to the administrative agent's approval. The new Revolving Credit Facility matures on November 24, 2030 and modified the financial and non-financial covenants to provide the Company additional flexibility. The new Revolving Credit Facility is unsecured and replaced the prior $400,000 revolving credit facility, which would have expired on December 15, 2026.

Borrowings in U.S. dollars under the Revolving Credit Facility bear interest, at a per annum rate equal to the applicable Term SOFR rate (but not less than 0.0%), plus the Term SOFR adjustment, and plus an applicable margin, which ranges from 1.00% to 1.75%, based on our net leverage ratio. Similarly, borrowings of alternative currencies under the Revolving Credit Facility bear interest equal to a defined risk-free reference rate, plus the applicable risk-free rate adjustment and plus an applicable margin, which ranges from 1.00% to 1.75%, based on our net leverage ratio. We use interest rate swaps to convert a portion of our Revolving Credit Facility's outstanding balance from a variable rate of interest to a fixed rate. The contractual rate of these arrangements ranges from 1.49% to 2.45%.

The Revolving Credit Facility includes a swing line sublimit of $20,000, a letter of credit sublimit of $20,000 and an alternative currency sublimit of $150,000. We also pay a quarterly commitment fee on the unused portion of the Revolving Credit Facility. The commitment fee ranges from 0.175% to 0.25% based on our net leverage ratio. We were in compliance with all debt covenants at December 31, 2025.

Our liquidity, access to capital, and borrowing costs could be adversely impacted by declines in our credit quality, our financial performance, and global credit market conditions, as well as a broad range of other factors. In addition, we have $75,943 of foreign cash balances and our ability to repatriate these funds timely and in a tax efficient manner may be restricted. See Item 1A. "Risk Factors” for additional discussion of risks that our business faces.

As of December 31, 2025, our material cash requirements for our known contractual and other obligations were as follows:

Long-term debt, including interest – Outstanding principal on our Revolving Credit Facility was $57,500 at December 31, 2025, with no amounts payable within 12 months. Additionally, we have minimum contractual future interest payments on our hedged borrowings under our Revolving Credit Facility estimated to be $12,035 through maturity, with approximately $2,721 payable within 12 months based on the December 31, 2025 exchange rate. We may paydown certain portions of these obligations early. As of December 31, 2025, we had interest rate swaps that fix interest costs on $50,000 of our long-term debt through December 2026 and a cross-currency swap on $7,500 of our long-term debt through June 2027. See Note 13, “Debt,” and Note 14, “Derivatives,” in the Notes to the Consolidated Financial Statements in this Annual Report on Form 10-K for further details of our debt and hedging activities.

Operating lease payments – We enter into various noncancelable lease agreements for land, buildings and equipment used in our operations. Operating lease obligations were $25,294 with $3,453 payable within 12 months. See Note 12, “Leases,” in the Notes to the Consolidated Financial Statements in this Annual Report on Form 10-K for further detail of our obligations and the timing of expected future payments.

Retirement obligations – Expected future contributions relating to our defined benefit postretirement plans were $3,178, with $421 payable in 12 months. See Note 7, “Retirement Plans,” in the Notes to the Consolidated Financial Statements in this Annual Report on Form 10-K for further detail of our obligations and the timing of expected future payments.

We have no off-balance sheet arrangements that have a material current effect or are reasonably likely to have a material future effect on our financial condition or changes in our financial condition.

Acquisitions

On July 29, 2024, we acquired 100% of the outstanding membership interests of SyQwest for $121,912 in cash subject to additional earnout payments based on future performance. The acquisition was funded from both cash on hand and borrowings under our previous revolving credit facility.

Critical Accounting Policies and Estimates

The Securities and Exchange Commission ("SEC") has defined a company’s critical accounting policies as the ones that are most important to the portrayal of a company’s financial condition and results of operations, and which require a company to make its most difficult and subjective judgments, often as a result of the need to make estimates of matters that are inherently uncertain. Based on this definition, we have identified the critical accounting policies and judgments addressed below. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances. Actual results may differ from these estimates.

Goodwill, Intangibles and Other Long-Lived Assets

Purchase Accounting

We use the acquisition method of accounting to allocate costs of acquired businesses to the assets acquired and liabilities assumed based on their estimated fair values at the dates of acquisition. The excess costs of acquired businesses over the fair values of the assets acquired and liabilities assumed are recognized as goodwill. The valuations of the acquired assets and liabilities assumed will impact the determination of future operating results. Determining the fair value of assets acquired and liabilities assumed requires management’s judgment and often involves the use of significant estimates and assumptions, including assumptions with respect to future cash inflows and outflows, revenue growth rates, discount rates, customer attrition rates, asset lives, contributory asset charges, and market multiples, among other items. We determine the fair values of intangible assets acquired generally in consultation with third-party valuation advisors.

Intangible assets other than goodwill are recognized if the benefit of the intangible asset is obtained through contractual or other legal rights, or if the intangible asset can be sold, transferred, licensed or exchanged, regardless of the Company’s intent to do so. Goodwill represents the excess purchase price over the fair value of the tangible net assets and intangible assets acquired in a business combination.

Impairment Assessment – Goodwill

Goodwill of a reporting unit is tested for impairment on the first day of its fiscal fourth quarter, or more frequently if an event occurs or circumstances change that would more-likely-than-not reduce the fair value of a reporting unit below its carrying amount. Examples of such events or circumstances include, but are not limited to, the following:

Significant decline in market capitalization relative to net book value,

Significant adverse change in regulatory factors or in the business climate,

Unanticipated competition,

More-likely-than-not expectation that a reporting unit or a significant portion of a reporting unit will be sold or otherwise disposed of,

Testing for recoverability of a significant asset group within a reporting unit, and

Allocation of a portion of goodwill to a business to be disposed.

If we believe that one or more indicators of impairment have occurred, we perform an impairment test.

CTS CORPORATION29

Table of Contents

We have the option to perform a qualitative assessment (commonly referred to as a "step zero" test) to determine whether further quantitative analysis for impairment of goodwill and indefinite-lived intangible assets is necessary. The qualitative assessment includes a review of macroeconomic conditions, industry and market considerations, internal cost factors, and our own overall financial and share price performance, among other factors. If, after assessing the totality of events or circumstances we determine that it is not more-likely-than-not that the fair value of a reporting unit is less than its carrying amount, we do not need to perform a quantitative analysis.

If a quantitative assessment is required, we estimate the fair value of each reporting unit using a combination of discounted cash flow analysis and market-based valuation methodologies. Determining fair value using a quantitative approach requires significant judgment, including judgments about projected revenues, cash flows over a multi-year period, discount rates and estimated valuation multiples. The discount rate applied to our forecasts of future cash flows is based on our estimated weighted average cost of capital. In assessing the reasonableness of our determined fair values, we evaluate our results against our market capitalization. Changes in these estimates and assumptions could materially affect the determination of fair value and impact the goodwill impairment assessment.

For 2025, we elected to perform the qualitative assessment on two of our reporting units, and the quantitative assessment on our third reporting unit. Based upon our latest assessment, we determined that our goodwill was not impaired as of October 1, 2025. We will monitor future results and will perform a test if indicators trigger an impairment review.

Impairment Assessment – Other Intangible Assets and Other Long-Lived Assets

We evaluate the impairment of identifiable intangibles and other long-lived assets whenever events or changes in circumstances indicate that the carrying value may not be recoverable. Factors considered that may trigger an impairment review consist of, but are not limited to, the following:

Significant decline in market capitalization relative to net book value,

Significant underperformance relative to expected historical or projected future operating results,

Significant changes in the manner of use of the acquired assets or the strategy for the overall business, and

Significant negative industry or economic trends.

If we believe that one or more indicators of impairment have occurred, we perform a recoverability test by comparing the carrying amount of an asset or asset group to the sum of the undiscounted cash flows expected to result from the use and the eventual disposition of the asset or asset group. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the fair value.

Income Taxes

Our income tax expense, deferred tax assets and liabilities, and liabilities for unrecognized tax benefits reflect management’s best estimate of current and future taxes to be paid. We are subject to income taxes in the United States and numerous foreign jurisdictions. Significant judgments and estimates are required in the determination of our consolidated income tax provision.

Deferred income taxes arise from temporary differences between the tax basis of assets and liabilities and their reported amounts in the financial statements, which will result in taxable or deductible amounts in the future. In evaluating our ability to recover our deferred tax assets in the jurisdictions from which they arise, we consider all available positive and negative evidence, including scheduled reversals of deferred tax liabilities, projected future taxable income, tax-planning strategies, and results of recent operations. The assumptions about future taxable income require the use of significant judgment and are consistent with the plans and estimates we are using to manage our underlying businesses.

The calculation of our tax liabilities involves dealing with uncertainties in the application of complex tax laws and regulations in a multitude of jurisdictions across our global operations. Accounting Standards Codification (“ASC”) 740 states that a tax benefit from an uncertain tax position may be recognized when it is more-likely-than-not that the position will be sustained upon examination, including resolution of any related appeals or litigation processes, on the basis of its technical merits. We record unrecognized tax benefits as liabilities in accordance with ASC 740 and adjust these liabilities when our judgment changes as a result of the evaluation of new information not previously available. Because of the complexity of some of these uncertainties, the ultimate resolution may result in a payment that is materially different from our current estimate of the unrecognized tax benefit liabilities. These differences will be reflected as increases or decreases to income tax expense in the period in which new information is available.

Revenue Recognition

We recognize revenue in accordance with the Financial Accounting Standards Board’s (“FASB”) ASC 606, Revenue from Contracts with Customers, net of estimated reserves. Our revenue reserves contain uncertainties because they require management to make assumptions and to apply judgment to estimate the value of future credits to customers for price adjustments. We base these estimates on the most likely value method considering all reasonably available information, including our historical experience and current expectations, and are reflected in the transaction price when sales are recorded.

CTS CORPORATION30

Table of Contents

Revenue is recognized as performance obligations are satisfied and the customer obtains control of the products. A portion of our contracts allow the customers to unilaterally terminate the contract for convenience, take control of any work in process, and pay us for costs incurred plus a reasonable profit. Revenue from these contracts is generally recognized over time as the work progresses, either as products are produced or services are rendered, because we generally do not have an alternative use for the completed assets produced and we have an enforceable right to payment for performance completed to date.

Significant estimates and assumptions are made in estimating total revenues, costs, and profit for each performance obligation. We generally estimate revenue for these contracts using the costs incurred by the Company as we have determined that this method is the most representative of the Company's cumulative efforts relative to the total expected efforts to satisfy the performance obligations. These estimates require significant judgment and are subject to change during the performance of the contract and may affect contract profitability.

Product Warranties

Provisions for estimated warranty expenses are made at the time products are sold. The expense and corresponding accrual primarily relate to our products sold to our transportation market. These estimates are established using a quoted industry rate and are based on customer specific circumstances. We adjust our warranty reserve for any known or anticipated warranty claims as new information becomes available. We evaluate our warranty obligations at least quarterly and adjust our accruals if it is probable that future costs will be different than our current reserve.

Over the last three years, product warranty reserves have ranged from 0.3% to 0.4% of net sales. We believe our reserve level is appropriate considering all facts and circumstances surrounding any outstanding quality claims and our historical experience selling our products to our customers.

Inventories

We value our inventories at the lower of the actual cost to purchase or manufacture using the first-in, first-out ("FIFO") method, or net realizable value. We review inventory quantities on hand and record a provision for excess and obsolete inventory based on historical consumption trends as well as forecasts of product demand including related production requirements. Once reserves are established, write-downs of inventory are considered permanent adjustments to the cost basis of inventory. Our reserves contain uncertainties because the calculation requires management to make assumptions and to apply judgment regarding historical experience, market conditions, and product life cycles. Changes in actual demand or market conditions could adversely impact our reserve calculations.

Over the last three years, our reserves for excess and obsolete inventories have ranged from 17.4% to 20.7% of gross inventory. We believe our reserve level is appropriate considering the quantities and quality of the inventories.

Environmental Contingencies

U.S. GAAP requires a liability to be recorded for contingencies when it is probable that a liability has been incurred and the amount of the liability can be reasonably estimated. We record environmental contingent loss accruals on an undiscounted basis. Significant judgment is required to determine the existence and amounts of our environmental liabilities. We regularly consult with attorneys and consultants to determine the relevant facts and circumstances before we record a liability. Changes in the estimates on which the accruals are based, unanticipated government enforcement action, or changes in health, safety, environmental, and chemical control regulations and testing requirements could, and have, resulted in higher or lower costs.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk

(in thousands, except percentages)

Our cash flows and earnings are subject to fluctuations resulting from changes in foreign currency exchange rates, interest rates and commodity prices. We manage our exposure to these market risks through internally established policies and procedures and, when deemed appropriate, through the use of derivative financial instruments. Our policies do not allow speculation in derivative instruments for profit or execution of derivative instrument contracts for which there are no underlying exposures. We do not use financial instruments for trading purposes, and we are not a party to any leveraged derivatives. We monitor our underlying market risk exposures on an ongoing basis and believe that we can modify or adapt our hedging strategies as needed.

CTS CORPORATION31

Table of Contents

Interest Rate Risk

We are exposed to risk of changes in interest rates on our Revolving Credit Facility. There was $57,500 and $92,300 outstanding under our Revolving Credit Facility at December 31, 2025 and 2024, respectively. As of December 31, 2025, we had interest rate swaps that fix interest costs on $50,000 of our long-term debt through December 2026 and a cross-currency interest rate swap on $7,500 of our long-term debt through June 2027. A 100-basis point change in interest rates would not materially impact our total interest expense.

Foreign Currency Risk

We are exposed to foreign currency exchange rate risks. Our significant foreign subsidiaries are located in China, Czech Republic, Denmark, Mexico, and Taiwan. During 2025, net sales from outside the U.S. were approximately 44% of total net sales. During 2024, net sales from outside the U.S. were approximately 42% of total net sales.

The Company’s foreign exchange exposures result primarily from the sale of products in foreign currencies, foreign currency denominated purchases, and employee-related and other costs of running operations in foreign countries. Changes in foreign exchange rates could affect the Company’s sales, costs, balance sheet values and earnings; therefore, we have entered into foreign currency forward contracts with notional values of $17,239 and $45,331 as of December 31, 2025 to hedge our exposure against the Euro and Mexican Peso, respectively.

In addition, we entered into a cross-currency interest rate swap agreement on June 27, 2022 that synthetically swapped $25,000 of variable rate debt to Krone denominated variable rate debt. Upon completion of the Ferroperm acquisition on June 30, 2022, the transaction was designated as a net investment hedge for accounting purposes and will mature on June 30, 2027. Accordingly, any gains or losses on this derivative instrument will be included in the foreign currency translation component of other comprehensive income until the net investment is sold, diluted or liquidated. Interest payments received for the cross currency-swap interest rate swap are excluded from the net investment hedge effectiveness assessment and are recorded in interest expense in the Condensed Consolidated Statements of Earnings. The assumptions used in measuring fair value of the cross-currency interest rate swap are considered level 2 inputs, which are based upon the Krone to United States Dollar exchange rate market. At December 31, 2025, we had a net unrealized loss of $1,719 in accumulated other comprehensive income (loss).

Commodity Price Risk

Many of our products require the use of raw materials that are produced in only a limited number of regions around the world or are available from only a limited number of suppliers. Our most significant raw materials and purchased components include conductive inks and contactors, passive connectivity components, integrated circuits and semiconductors, certain rare earth elements ("REEs"), ceramicpowders, plastic components, molding compounds, printed circuit boards and assemblies, quartz blanks and crystals, wire harness assemblies, copper, brass, silver, gold,platinum, lead, aluminum, titanium and steel-based raw materials and components.

Our results of operations may be materially and adversely affected if we have difficulty obtaining these raw materials, the quality of available raw materials deteriorates, or there are significant price increases for these raw materials. For periods in which the prices of these raw materials are rising, we may be unable to pass on the increased cost to our customers, which would result in decreased margins for the products in which they are used. For periods in which the prices are declining, we may be required to write down our inventory carrying cost of these raw materials, since we record our inventory at the lower of cost or net realizable value.

As the Company is exposed to significant changes in these commodity prices, we actively monitor these exposures and may take various actions from time to time to mitigate any negative impacts relating thereto.

Item 8. Financial Statements and Supplementary Data

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Board of Directors and Shareholders

CTS Corporation

Opinion on the financial statements

We have audited the accompanying consolidated balance sheets of CTS Corporation (an Indiana corporation) and subsidiaries (the “Company”) as of December 31, 2025 and 2024, the related consolidated statements of earnings, comprehensive earnings, shareholders’ equity, and cash flows for each of the three years in the period ended December 31, 2025, and the related notes and financial statement schedules included under Item 15(a) (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2025 and 2024, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2025, in conformity with accounting principles generally accepted in the United States of America.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (“PCAOB”), the Company’s internal control over financial reporting as of December 31, 2025, based on criteria established in the 2013 Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”), and our report dated February 24, 2026 expressed an unqualified opinion.

Basis for opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s consolidated financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the 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 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 financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical audit matters

The critical audit matterscommunicated below are mattersarising from the current period audit of the financial statements that were communicated or are required to be communicated to the audit committee and that: (1) relateto accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit mattersbelow, providing separate opinionson the critical audit mattersor on the accounts or disclosures to which they relate.

Over time revenue recognition – estimation of costs at completion

As described in Note 2 to the consolidated financial statements, the Company has certain customer contracts that allow the customers to unilaterally terminate the contract for convenience, take control of any work in process, and pay the Company for costs incurred plus a reasonable profit. Revenue from these contracts is generally recognized over time as the work progresses, either as products are produced or services are rendered, because the Company does not have an alternative use for the completed assets produced, and the Company has an enforceable right to payment for performance completed to date. The accounting for these contracts requires significant management judgment with respect to the estimation of costs at completion for each performance obligation. We have identified the Company’s estimation of costs at completion for its over time revenue contracts as a critical audit matter.

The principal consideration for our determination that the estimation of costs at completion is a critical audit matter is the significant degree of management judgment required to evaluate the estimated labor and material costs for each contract, which are assumptions with a high level of estimation uncertainty and susceptibility to potential management bias.

CTS CORPORATION33

Table of Contents

Our audit procedures related to the critical audit matter included the following, among others. We tested the Company’s assumptions for labor hours and materials to be incurred for a selection of in-process contracts as follows:

Inspected a sample of underlying contracts to obtain an understanding of the contractual requirements and deliverables and the nature of the costs necessary to fulfill those contracts;

Agreed a sample of actual labor and material costs incurred to supporting documentation, verifying the costs were accurate and classified to the appropriate contracts;

Recalculated revenue recognized to date through comparison of actual costs incurred to date as a percentage of the estimated total contract costs at completion, and applied that percentage to the underlying contract price; and

Evaluated the Company’s ability to accurately estimate costs at completion through 1) an evaluation of the competence and experience of the key operational executive who is responsible for developing the estimated costs at completion and 2) the selection of completed contracts in order to compare the Company’s initial estimated costs and profit margin to the actual costs and profit margin at the completion of the contracts.

Quantitative goodwill impairment assessment

The Company’s consolidated goodwill balance was $209.6 million as of December 31, 2025. As described in Note 1 and Note 8 to the consolidated financial statements, the Company evaluates goodwill for impairment at the reporting unit level annually. A quantitative impairment assessment was performed as of October 1, 2025 for one of the Company’s three reporting units. The goodwill balance for this reporting unit amounts to $48.8 million. The quantitative impairment assessment involves the comparison of the fair value of a reporting unit to its carrying value. The Company determines the fair value of the reporting unit using a combination of discounted cash flow analysis and a market-based valuation methodology, which requires significant management judgment. We have identified the quantitative goodwill impairment assessment as a critical audit matter.

The principal consideration for our determination that the quantitative goodwill impairment assessment is a critical audit matter is the significant auditor judgment required to evaluate the reporting unit’s forecasted revenues and EBITDA and the Company’s selection of the discount rate.

Our audit procedures related to the critical audit matter included the following, among others:

Tested the design and operating effectiveness of the key controls over the Company’s quantitative goodwill impairment assessment, including controls over the development of the significant assumptions such as the forecasted revenues, EBITDA, and the discount rate;

Evaluated a selection of the customer contracts to support the reasonableness of the reporting unit’s forecasted revenues that pertain to recurring contracts;

Corroborated management’s probability evaluation of future contract awards by inspecting correspondence with third parties, evaluating publicly available information, and reviewing subsequent information to identify evidence consistent with management’s forecasted revenues for the future contract awards;

Evaluated the forecasted revenues and EBITDA for the reporting unit by comparing the forecasted growth assumptions to both current and historical results, as well as forecasted industry trends; and

Assessed the Company’s discount rate for the reporting unit by comparing it against a discount rate independently developed using publicly available market data for comparable peers and evaluating management’s sensitivity analysis over the selected company specific risk premium.

Specialists were involved in evaluating the valuation methodology and significant assumptions such as the discount rate.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(in thousands, except for share and per share data)

NOTE 1 — Summary of Significant Accounting Policies

Description of Business: CTS Corporation ("CTS", "we", "our", "us" or the "Company") is a global manufacturer of sensors, connectivity components, and actuators operating as a single reportable business segment. We operate manufacturing facilities located throughout North America, Asia and Europe and service major markets globally.

Principles of Consolidation: The consolidated financial statements include the accounts of CTS and its wholly owned subsidiaries. All significant intercompany accounts and transactions have been eliminated.

Use of Estimates: The preparation of financial statements in conformity with the accounting principles generally accepted in the United States of America ("U.S. GAAP") requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ materially from those estimates.

Cash and Cash Equivalents: All highly liquid investments with maturities of three months or less at the date of purchase are considered to be cash equivalents.

Accounts Receivable and Allowance for Credit Losses: Accounts receivable consists primarily of amounts due from normal business activities. We maintain an allowance for credit losses for estimated uncollectible accounts receivable. Our reserves for estimated credit losses are based upon historical experience, specific customer collection issues, current conditions and reasonable and supportable forecasts that affect the collectability of the remaining cash flows over the contractual terms of our receivables and other financial assets. Accounts are written off against the allowance account when they are determined to no longer be collectible.

Concentration of Credit Risk: Financial instruments that potentially subject us to concentrations of credit risk consist of cash and cash equivalents and trade receivables. Our cash and cash equivalents, at times, may exceed federally insured limits. Cash and cash equivalents are deposited primarily in banking institutions with global operations. We have not experienced any losses in such accounts. We believe we are not exposed to any significant credit risk related to cash and cash equivalents.

Trade receivables subject us to the potential for credit risk with major customers. We sell our products to customers principally in the aerospace and defense, industrial, medical, and transportation markets, primarily in North America, Europe, and Asia. We perform ongoing credit evaluations of our customers to minimize credit risk. We do not require collateral.

Our net sales to significant customers as a percentage of total net sales were as follows:

Year Ended December 31,

No other customer accounted for 10% or more of total net sales during these periods.

Inventories: We value our inventories at the lower of the actual cost to purchase or manufacture using the first-in, first-out ("FIFO") method, or net realizable value. We review inventory quantities on hand and record a provision for excess and obsolete inventory based on historical consumption trends as well as forecasts of product demand including related production requirements. Once reserves are established, write-downs of inventory are considered permanent adjustments to the cost basis of inventory. Our reserves contain uncertainties because the calculation requires management to make assumptions and to apply judgment regarding historical experience, market conditions, and product life cycles. Changes in actual demand or market conditions could adversely impact our reserve calculations.

Property, Plant and Equipment: Property, plant and equipment is stated at cost, less accumulated depreciation. Depreciation is computed primarily over the estimated useful lives of the various classes of assets using the straight-line method. Useful lives for buildings and improvements range from 10 to 45 years, machinery and equipment from three to 15 years, and software from two to 15 years. Depreciation on leasehold improvements is computed over the lesser of the lease term or estimated useful lives of the assets. Amounts expended for maintenance and repairs are charged to expense as incurred. Major overhauls that extend the useful lives of existing assets are capitalized. Upon disposition, any related gains or losses are included in operating earnings.

Income Taxes: We account for income taxes under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements. Under this method, we determine deferred tax assets and liabilities on the basis of the differences between the financial statement and tax bases of assets and liabilities by using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period that includes the enactment date.

We recognize deferred tax assets to the extent that we believe that these assets are more-likely-than-not to be realized. In making such a determination, we consider all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax-planning strategies, and results of recent operations. If we determine that we would be able to realize our deferred tax assets in the future in excess of their net recorded amount, we would make an adjustment to the deferred tax asset valuation allowance, which would reduce the provision for income taxes.

We record uncertain tax positions in accordance with Accounting Standards Codification ("ASC") Topic 740 on the basis of a two-step process in which (1) we determine whether it is more-likely-than-not that the tax positions will be sustained on the basis of the technical merits of the position and (2) for those tax positions that meet the more-likely-than-not recognition threshold, we recognize the largest amount of tax benefit that is more than 50 percent likely to be realized upon ultimate settlement with the related tax authority.

We recognize interest and penalties related to unrecognized tax benefits on the income tax expense line in the accompanying Consolidated Statements of Earnings. Accrued interest and penalties are included in the related tax liability line in the Consolidated Balance Sheets.

See Note 19, "Income Taxes," for further information.

Goodwill and Indefinite-lived Intangible Assets: Goodwill represents the excess of the purchase price over the fair values of the net assets acquired in a business combination. In accordance with ASC 350, Intangibles—Goodwill and Other, goodwill is not amortized, but instead is tested for impairment annually or more frequently if circumstances indicate a possible impairment may exist. Absent any interim indicators of impairment, the Company tests for goodwill impairment as of the first day of its fourth fiscal quarter of each year.

Based upon our latest assessment, we determined that our goodwill was not impaired as of October 1, 2025.

Other Intangible Assets and Long-lived Assets: We account for long-lived assets (excluding indefinite-lived intangible assets) in accordance with the provisions of ASC 360, Property, Plant, and Equipment. This statement requires that long-lived assets, which includes fixed assets and finite-lived intangible assets, be reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. If an impairment test is warranted, recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to the sum of the undiscounted cash flows expected to result from the use and the eventual disposition of the asset. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount in which the carrying amount of the assets exceeds the fair value of the assets. Assets to be disposed of are reported at the lower of the carrying amount or fair value less costs to sell.

Intangible assets (excluding indefinite-lived intangible assets) consist primarily of technology, customer lists and relationships, patents, and trade names. These assets are recorded at cost and are usually amortized on a straight-line basis over their estimated lives. We assess useful lives based on the period over which the asset is expected to contribute to cash flows.

Revenue Recognition: Product revenue is recognized upon the transfer of promised goods to a customer in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods net of reserves. We follow the five step model to determine when this transfer has occurred: 1) identify the contract(s) with the customer; 2) identify the performance obligations in the contract; 3) determine the transaction price; 4) allocate the transaction price to the performance obligations in the contract; and 5) recognize revenue when (or as) the entity satisfies a performance obligation.

Research and Development: Research and development ("R&D") costs include expenditures for search and investigation aimed at discovery of new knowledge to be used to develop new products or processes or to significantly enhance existing products or production processes. R&D costs also include the implementation of new knowledge through design, testing of product alternatives, or construction of prototypes. We expense all R&D costs as incurred, net of customer reimbursements for sales of prototypes and non-recurring engineering charges.

We create prototypes and tools related to R&D projects. A prototype is defined as a constructed product not intended for production resulting in a commercial sale. We also incur engineering costs related to R&D activities. Such costs are incurred to support activities to improve the reliability, performance and cost-effectiveness of our existing products and to design and develop innovative products that meet customer requirements for new applications. Furthermore, we may engage in activities that develop tooling machinery and equipment for our customers.

We occasionally enter into agreements with our customers whereby we receive a contractual guarantee based on achieving milestones to be reimbursed for the costs we incur in the product development process or to construct molds, dies, and other tools that are used to make many of the products we sell. The costs we incur are included in other current assets on the Consolidated Balance Sheets until reimbursement is received from the customer. Reimbursements received from customers are netted against such costs and included in our Consolidated Statements of Earnings if the amount received is in excess of the costs that we incur. The following is a summary of amounts to be received from customers as of December 31, 2025 and 2024:

As of December 31,

Financial Instruments: We use forward contracts to mitigate currency risk related to forecasted foreign currency revenue and costs. These forward contracts are designed as cash flow hedges. At least quarterly, we assess the effectiveness of these hedging relationships based on the total change in their fair value using regression analysis. In addition, we use interest rate swaps to convert a portion of our revolving credit facility's variable rate of interest into a fixed rate. As a result of the use of these derivative instruments, the Company is exposed to the risk that counterparties to derivative contracts will fail to meet their contractual obligations. To mitigate the counterparty credit risk, the Company has a policy of only entering into contracts with carefully selected major financial institutions based upon their credit ratings and other factors and by using netting agreements. Our established policies and procedures for mitigating credit risk on principal transactions include reviewing and establishing limits for credit exposure and continually assessing the creditworthiness of counterparties.

We estimate the fair value of our cash, cash equivalents, accounts receivable and accounts payable at cost due to the short-term nature of these instruments. Please refer to Note 13, "Debt," and Note 15, "Accumulated Other Comprehensive Income (Loss) ," for information on the method of determining fair value for our debt and financial derivatives, respectively.

Stock-Based Compensation: We recognize expense related to the fair value of stock-based compensation awards, consisting of restricted stock units ("RSUs"), cash-settled restricted stock units, and performance share units ("PSUs") in the Consolidated Statements of Earnings.

The grant date fair values of our service-based and performance-based RSUs are the closing price of our common stock on the date of grant. Our RSU awards primarily have a graded vesting schedule. We recognize expense on a straight-line basis over the requisite service period for each separately vesting tranche of the award as if the award was, in substance, multiple awards. Compensation expense for PSUs is measured by determining the fair value of the award using the closing share price on the grant date and is recognized ratably from the grant date to the vesting date for the number of awards expected to vest. The amount of compensation expense recognized for PSUs is dependent upon a quarterly assessment of the likelihood of achieving the performance conditions and is subject to adjustment based on management's assessment of the Company's performance relative to the target number of shares performance criteria. Forfeitures are recorded as they occur.

See Note 17, "Stock-Based Compensation," for further information.

Earnings Per Share: Basic earnings per share excludes any dilution and is computed by dividing net earnings available to common shareholders by the weighted-average number of common shares outstanding for the period.

CTS CORPORATION42

Table of Contents

Diluted earnings per share is calculated by dividing net earnings by the weighted average shares outstanding assuming dilution. Dilutive common shares outstanding is computed using the Treasury Stock Method and reflects the additional shares that would be outstanding if dilutive stock options were exercised, and restricted stock units were settled for common shares during the period. In addition, dilutive shares include any shares issuable related to performance share units for which the performance conditions would have been met as of the end of the period and therefore would be considered contingently issuable. If the common stock equivalents have an anti-dilutive effect, they are excluded from the computation of diluted earnings per share. If there is a net loss for the period, then basic earnings per share equals diluted earnings per share.

Our antidilutive securities consist of the following:

Years Ended December 31,

Foreign Currencies: The financial statements of the majority of our non-U.S. subsidiaries are remeasured into U.S. dollars using the U.S. dollar as the functional currency with all remeasurement adjustments included in the determination of net earnings.

Foreign currency gains / losses recorded in the Consolidated Statements of Earnings includes the following:

Years Ended December 31,

The assets and liabilities of our non-U.S. dollar functional subsidiaries are translated into U.S. dollars at the current exchange rate at period end, with the resulting translation adjustments made directly to the "accumulated other comprehensive income (loss)" component of shareholders' equity. Our Consolidated Statements of Earnings accounts are translated at the average rates during the period.

Shipping and Handling: All fees billed to the customer for shipping and handling are classified as a component of net sales. All costs associated with shipping and handling are classified as a component of cost of goods sold or operating expenses, depending on the nature of the underlying purchase.

Sales Taxes: When applicable, we classify sales taxes on a net basis in our consolidated financial statements.

Immaterial Correction of Prior Period Errors

As reported in our Quarterly Report on Form 10-Q for the quarterly period ended March 31, 2025, the Company identified immaterial prior period errors in the consolidated financial statements related to the acquisition of SyQwest, LLC (“SyQwest”) as well as the foreign currency impact on certain long-term debt payments. The errors related to the SyQwest acquisition were due to errors with the calculation of revenue and cost of goods sold both prior to and subsequent to the acquisition date of July 29, 2024. The Company assessed the materiality of this change on prior period consolidated financial statements in accordance with SEC Staff Accounting Bulletin No. 99, “Materiality” (ASC Topic 250, Accounting Changes and Error Corrections). Based on this assessment, the Company concluded that these error corrections were material in the first quarter of 2025, but were not material to any previously presented consolidated financial statements. Accordingly, the Company corrected the previously reported immaterial errors for the year ended December 31, 2024 in its Quarterly Report on Form 10-Q for the quarterly period ended March 31, 2025.

The financial reporting periods affected by this error include the Company’s previously reported audited consolidated financial statements for the fiscal year ended December 31, 2024 and the Company’s previously reported interim unaudited consolidated financial statements for the three and nine months ended September 30, 2024. The Company is presenting the corrected 2024 amounts in this Annual Report on Form 10-K on a year-to-date basis. A summary of the immaterial corrections to the Company’s previously reported audited and unaudited consolidated financial statements follows.

During the fourth quarter of 2025, the Company identified additional immaterial prior period errors related to the acquisition of SyQwest. The errors related to the calculation of revenue and cost of goods sold that originated prior to the acquisition date of July 29, 2024 and continued through 2025. The Company assessed the materiality of this change on prior period consolidated financial statements in accordance with SEC Staff Accounting Bulletin No. 99, “Materiality” (ASC Topic 250, Accounting Changes and Error Corrections). Based on this assessment, the Company concluded that these error corrections are not material to the current or previously presented consolidated financial statements. Accordingly, the Company corrected the immaterial errors during the period ending December 31, 2025 impacting Revenue, Cost of goods sold, Other income (expense) and Goodwill resulting in decreased earnings before taxes of $893. The correction includes a $2,194 adjustment to Goodwill related to errors originating prior to the acquisition date.

NOTE 2 – Revenue Recognition

CTS designs and manufactures sensors, actuators, and electronic components for original equipment manufacturers and the U.S. Government. For each contract with a customer, we determine the transaction price based on the consideration expected to be received by the Company in exchange for performing its obligations under the applicable contract. We allocate the transaction price to each distinct performance obligation to deliver a good or service, or a collection of goods and/or services, based on the relative standalone selling prices. We usually expect payment from our customers within 30 to 90 days from the shipping date or invoicing date, depending on our terms with the customer. None of our contracts as of December 31, 2025 or 2024 contained a significant financing component. Differences between the amount of revenue recognized and the amount invoiced, collected from, or paid to our customers are recognized as contract assets or liabilities. Contract assets will be reviewed for impairment when events or circumstances indicate that they may not be recoverable.

To the extent the transaction price includes variable consideration, we estimate the amount of variable consideration that should be included in the transaction price utilizing the most likely value method based on an analysis of historical experience and current facts and circumstances, which may require significant judgment. Variable consideration is included in the transaction price if, in our judgment, it is probable that a significant future reversal of cumulative revenue under the contract will not occur.

Our revenue reserves contain uncertainties because they require management to make assumptions and to apply judgment to estimate the value of future credits to customers for product returns, price adjustments, and stock rotation adjustments. We base these estimates on the most likely value method considering all reasonably available information, including our historical experience and current expectations, and are reflected in the transaction price when sales are recorded.

Approximately 96% of our revenue is derived from contracts for sales of commercial products, which generally contain a single performance obligation. We generally recognize revenue at a point in time on the delivery date based on the shipping terms stipulated in the contract.

We also design, manufacture, and test products for certain customers under contracts that allow the customers to unilaterally terminate the contract for convenience, take control of any work in process, and pay us for costs incurred plus a reasonable profit. Revenue from these contracts is generally recognized over time as the work progresses, either as products are produced or services are rendered, because we generally do not have an alternative use for the completed assets produced and we have an enforceable right to payment for performance completed to date. These contracts may contain a single or multiple performance obligations. The accounting for these contracts involves applying significant judgment with respect to estimating total revenues, costs and profit for each performance obligation. We generally estimate revenue for these contracts using the costs incurred by the Company as we have determined that this method is the most representative of the Company's cumulative efforts relative to the total expected efforts to satisfy the performance obligations. Approximately 4% of the Company's revenue is recognized over time.
