PART I

Item 1. Business

CTS Corporation ("CTS", "we", "our", "us" or the "Company") is a global manufacturer of sensors, connectivity components, and actuators. CTS was established in 1896 as a provider of high-quality telephone products and was incorporated as an Indiana corporation in February 1929. Our principal executive offices are located in Lisle, Illinois.

We design, manufacture, and sell a broad line of sensors, connectivity components, and actuators primarily to original equipment manufacturers ("OEMs") and tier one suppliers for the aerospace and defense, industrial, information technology, medical, telecommunications, and transportation markets. 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 operate manufacturing facilities in North America, Asia, and Europe. Sales and marketing are accomplished through our sales engineers, independent manufacturers' representatives, and distributors.

See the Consolidated Financial Statements and Notes included in Part II, Item 8 of this Annual Report on Form 10-K for financial information regarding the Company.

MARKETING AND DISTRIBUTION

Sales and marketing to customers is accomplished through our sales engineers, independent manufacturers' representatives, and distributors. We maintain sales offices in China, Czech Republic, Denmark, Germany, Japan, Singapore, Taiwan, and the United States. Approximately 88% of 2020 net sales were attributable to our sales engineers.

Our sales engineers generally service our largest customers with application-specific products. The sales engineers work closely with major customers in designing and developing products to meet specific customer requirements.

We utilize the services of independent manufacturers' representatives for customers not serviced directly by our sales engineers. Independent manufacturers' representatives receive commissions from us. During 2020, approximately 6% of net sales were attributable to independent manufacturers' representatives. We also use independent distributors. Independent distributors purchase products from us for resale to customers. In 2020, independent distributors accounted for approximately 6% of net sales.

RAW MATERIALS

We utilize a wide variety of raw materials and purchased parts in our manufacturing processes. The following are the most significant raw materials and purchased components:

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, and steel-based raw materials and components.

These raw materials and parts are purchased from a number of suppliers, and we generally do not believe we are dependent upon one or a limited number of suppliers. Although we purchase all of our semiconductors, REEs, conductive inks, and silver pastes from a limited number of suppliers, alternative sources are generally available.

Lead times between the placement of orders for certain raw materials and purchased parts and actual delivery to us may vary. Occasionally, we may need to order raw materials in greater quantities and at higher prices to compensate for the variability of lead times for delivery. The price and availability of raw materials and manufactured components is subject to change due to, among other things, new laws and regulations, global economic and political events including strikes, and public health and safety concerns.

The continued uncertainties due to the COVID-19 pandemic may adversely affect our ability to source materials.

PATENTS, TRADEMARKS, AND LICENSES

We maintain a program of obtaining and protecting U.S. and non-U.S. patents relating to products that we have designed and manufactured, as well as processes and equipment used in our manufacturing technology. We were issued 7 new U.S. patents and 12 non-U.S. patents in 2020 and currently hold 134 U.S. patents and 129 non-U.S. patents. We have 10 registered U.S. trademarks, 24 registered foreign trademarks and 4 international trademark registrations. We have licensed the right to use several of our patents. In 2020, license and royalty income was less than 1% of net sales.

MAJOR CUSTOMERS

Sales to our 15 largest customers as a percentage of total net sales were as follows:

Years Ended December 31,

Total of 15 largest customers / net sales 59.4% 61.9% 63.7%

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

Years Ended December 31,

We sell parts to these three transportation customers for certain vehicle platforms under purchase agreements that have program lifetime volume estimates and are subject to purchase orders issued from time to time.

CTS CORPORATION 5

No other customer accounted for 10% or more of total net sales during these periods. We continue to focus on broadening our customer base to diversify our end market exposure.

Changes in the level of our customers' orders have, in the past, had a significant impact on our operating results. If a major customer reduces the amount of business it transacts with us, or substantially changes the terms of that business, there could be an adverse impact on our operating results.

ORDER BACKLOG

Order backlog is comprised of firm open purchase orders we have received from our customers and generally represents 1 to 2 months of sales for certain products. Our business is a mix of purchase order-based business, shorter-term contracts, and multi-year awards, such as with customers who serve the automotive end market. As such, order backlog does not provide a meaningful indication of future sales.

COMPETITION

We compete with domestic and foreign manufacturers principally based on product features, technology, price, quality, reliability, delivery, and service. Most of our product lines encounter significant global competition. The number of competitors varies from product line to product line. No one competitor competes with us in every product line, but some competitors are larger and more diversified than we are.

Some customers have reduced or plan to reduce their number of suppliers, while increasing their volume of purchases. Customers demand lower cost and higher quality, reliability, and delivery standards from us as well as from our competitors. These trends create opportunities for us, but also increase the risk of loss of business to competitors. We are subject to competitive risks that are typical in our end markets, including technical obsolescence.

We believe we compete most successfully in custom engineered products manufactured to meet specific applications of major OEMs.

NON-U.S. REVENUES AND OPERATIONS

Our net sales to customers originating from our non-U.S. operations as a percentage of total net sales were as follows:

Years Ended December 31,

Net sales from non-U.S. operations 43% 40% 33%

We believe the business risks to our non-U.S. operations, though substantial, are normal risks for global businesses. These risks include currency controls and changes in currency exchange rates, longer collection cycles, political and transportation risks, economic downturns and inflation, government regulations, and expropriation. Our non-U.S. manufacturing facilities are located in China, Czech Republic, Denmark, Mexico, Philippines, and Taiwan. Additional information regarding the Company’s sales by geographic area and long-lived tangible assets in different geographic areas is included in Note 20 - Geographic Data.

HUMAN CAPITAL RESOURCES

We employed 3,786 people at December 31, 2020, with 87% of these employees located outside the U.S. We employed 3,570 people at December 31, 2019 with 84% of these employees located outside the U.S.

We are committed to building a diverse, inclusive and engaged workforce. Our management teams and all of our employees are expected to exhibit the principles of fairness, honesty and integrity in the actions we undertake. Our employees must adhere to a code of conduct that sets standards for appropriate behavior and includes required annual training on preventing, identifying, reporting and stopping any type of unlawful discrimination or unethical actions.

We have a global talent review and succession planning process designed to align our talent plans with the current and future strategies of the business. This includes the identification of key positions, assessment of internal talent and potential successors and plans for talent acquisition and development.

We strive to align compensation with the external market and maintain equity within the organization. In addition, we offer a broad range of company-paid benefits, which we believe are competitive in our industry.

The safety of our employees is a priority and vital to our success. Our employees are regularly trained on safety-related topics and we monitor and measure our effectiveness at all of our locations.

During fiscal 2020, in response to the COVID-19 pandemic, we took action to protect our employees’ safety and health, including equipping employees with personal protective equipment, establishing minimum staffing and social distancing policies, sanitizing workspaces more frequently, adopting alternate work schedules including encouraging remote work arrangements, and instituting other measures aimed at minimizing the transmission of COVID-19 while sustaining production and related services. In addition, we modified the way we conduct many aspects of our business to reduce the number of in-person interactions. For example, we significantly expanded the use of virtual interactions in many aspects of our business, including customer facing activities.

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. 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. 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, 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 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 margins 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.

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.

CTS CORPORATION 8

Table of Contents

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 again 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.

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 failure of manufacturers that we serve may result in the failure to receive payment in full for products sold in the past and an abrupt cancellation in demand for certain products. Weakness in demand, the insolvency of manufacturers 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 often 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 experience shortages and increased costs of raw material and required electronic components.

Unanticipated raw material or electronic component shortages may 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 inflationary trends regardless of supply. We are also dependent on our suppliers' ability to supply and deliver raw materials on a timely basis at negotiated prices. Any delay or inability to deliver raw materials by our suppliers may require that we attempt to mitigate such failure or fail to make deliveries to our customers on a timely basis. As a result, raw material or electronic component shortages, price increases, or failure to perform by our suppliers could adversely affect our operating results for a particular period due to the resulting revenue shortfall and/or increased costs.

We may pursue acquisition opportunities that 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. We may have difficulty finding suitable 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 our newly acquired 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.

CTS CORPORATION 9

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 recent 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. 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 may be unable to compete effectively against competitors.

The industries in which we operate are highly competitive and characterized by price erosion and rapid 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, it 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 and the products we manufacture for others vary, 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.

Despite our quality control and quality assurance efforts, 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 in the transportation and medical device markets, 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 violate EHS laws and regulations, we could be liable for

CTS CORPORATION 10

Table of Contents

substantial fines, penalties, and costs of mandated remedial actions. 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, 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 U.S. Environmental Protection Agency’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. 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 existing sites, 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.

In addition, we could be affected by future laws or regulations imposed in response to climate change concerns. Such laws or regulations could have a material adverse effect on our business, financial condition, and results of operations. Climate change initiatives may result in significant operational changes and expenditures, reduce demand for our products and adversely affect our business. We recognize that climate change is a global environmental concern. 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. These agreements and measures may require equipment modifications, operational changes, taxes, or purchase of emission credits to reduce emission of greenhouse gases from our operations, which may result in substantial capital expenditures and compliance, operating, maintenance and remediation costs. Regulatory initiatives to reduce greenhouse gas usage may also adversely impact some of the industries we serve and our supply chain, adversely impacting our sales and the value of our business.

Regulations related to conflict minerals could adversely impact our business.

The Dodd-Frank Wall Street Reform and Consumer Protection Act contains provisions to improve transparency and accountability concerning the supply of certain minerals, known as conflict minerals, originating from the Democratic Republic of Congo ("DRC") and adjoining countries. As a result, the SEC adopted annual disclosure and reporting requirements for those companies who may use conflict minerals mined from the DRC and adjoining countries in their products. There have been and will continue to be costs associated with complying with these disclosure requirements, including diligence costs to determine the sources of minerals used in our products and other potential changes to products, processes or sources of supply to the extent necessary as a consequence of such verification activities. These rules could adversely affect the sourcing, supply and pricing of materials used in our products. As there may be only a limited number of suppliers offering conflict-free minerals, we cannot be sure that we will be able to obtain necessary conflict-free minerals from such suppliers in sufficient quantities or at competitive prices. Also, we may face reputational challenges if we determine that certain of our products contain conflict minerals or if we are unable to sufficiently verify the origins for all minerals used in our products through the procedures we may implement.

Negative or unexpected tax consequences could adversely affect our results of operations.

We operate globally and changes in tax laws could adversely affect our results. The international tax environment continues to change as a result of both coordinated actions by governments and unilateral measures enacted by individual countries, such as the comprehensive tax reform enacted in the U.S. in 2017, which could significantly impact our effective tax rate, tax liabilities, and ability to utilize deferred tax assets.

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.

Risks Related to Indebtedness and Financing

Our indebtedness may adversely affect our financial health.

CTS CORPORATION 11

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. Moreover, an increase in interest rates could increase our interest expense.

Our credit facility contains provisions that could materially restrict 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.

Losses in the financial markets could negatively impact pension asset returns and cash flow due to possible required contributions in the future.

We make a number of assumptions relating to our pension plans in order to measure the financial position of the plans and the net periodic benefit cost. The most significant assumptions relate to the discount rate and the expected long-term return on plan assets. If these assumptions prove to be significantly different from actual rates, then we may need to record additional expense relating to the pension plans, which could require cash contributions to fund future pension obligation payments and could have a material adverse effect on our financial condition and results of operations.

Risks Related to COVID-19 Pandemic and Other External Factors

Public health issues such as the COVID-19 pandemic have adversely affected, and could in the future, adversely affect our business or financial results.

The United States and other countries have experienced, and may experience in the future, outbreaks of contagious diseases that affect public health. In connection with the outbreak of the global COVID-19 pandemic in 2020, the United States declared a national emergency in March 2020 and the World Health Organization, and the U.S. Centers for Disease Control and Prevention have recommended containment and mitigation measures. Numerous states and municipalities have also declared public health emergencies. Along with these declarations, extraordinary and wide-ranging actions have been taken by international, federal, state, and local public health and governmental authorities to mitigate the impact of COVID-19, including quarantines, stay-at-home orders and business closure mandates requiring that individuals substantially restrict daily activities and that businesses substantially modify, curtail or cease normal operations. Many of these measures are currently in place in many jurisdictions where we operate, and additional measures may be imposed by governmental authorities in the future. There is significant uncertainty regarding the extent to which and how long COVID-19 and related government directives, actions and economic relief efforts will disrupt the global economy and level of employment, capital markets, consumer confidence, and demand for our products. The extent to which COVID-19 impacts our operational and financial performance will depend on future developments, including the duration and spread of COVID-19, the acceptance and effectiveness of vaccines, and the impact of COVID-19 and related containment and mitigation measures on our customers, trade partners and employees, all of which are highly uncertain, unpredictable and outside our control. If COVID-19 continues to have a significant negative impact on economic conditions over a prolonged period of time, the pandemic could have a material adverse effect on our financial condition and results of operations.

Natural disasters may adversely impact our capability to supply product to our customers.

Natural disasters, such as storms, flooding and associated power outages, occurring at any of our locations or supplier locations may lead to disruption of our manufacturing operations and supply chain, adversely impacting our capability to supply product to our

CTS CORPORATION 12

Table of Contents

customers. In the event of a natural disaster, it may not be possible for us to find an alternate manufacturing location for certain product lines, further impacting our capability to recover from such a disruption.

General Risk Factors

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; 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 management of international operations. In addition, these same factors may also place us at a competitive disadvantage compared to some of our foreign competitors.

We may face risks associated with violations of the Foreign Corrupt Practices Act ("FCPA") and similar anti-bribery laws. The FCPA and similar anti-bribery laws in other jurisdictions 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 the detrimental actions by our employees or agents. If we are found to be liable for FCPA violations (either due to our own acts or inadvertence or due to the acts or inadvertence of others), we could suffer from 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, including measures implemented in response to the global COVID-19 pandemic, 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 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 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

CTS CORPORATION 13

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. Competition for qualified employees among companies that rely heavily on engineering and technology is at times intense, and the loss of qualified employees or an inability to attract, retain and motivate additional highly skilled employees required for the operation and expansion of our business could hinder our ability to conduct research and development activities and deliver marketable products successfully.

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.

We could face risks to our systems, networks and production including increased IT security threats and more sophisticated and targeted computer crime.

Increased global information technology security threats and more sophisticated and targeted computer crime pose a risk to the security of our systems and networks and the confidentiality, availability and integrity of our data and communications. While we attempt to mitigate these risks by employing a number of measures - including employee training, comprehensive monitoring of our networks and systems, and maintenance of backup and protective systems - our systems, networks and products remain potentially vulnerable to advanced persistent threats. Depending on their nature and scope, such threats could potentially lead to the compromising of confidential information and communications, improper use of our systems and networks, manipulation and destruction of data, defective products, production downtimes and operational disruptions, which in turn could adversely affect our reputation, competitiveness and results of operations. Additionally, any updates to or implementation of systems, including the selection and implementation of an ERP system, may cause delays or disruptions in our processes or production which could adversely affect our results. The regulatory environment surrounding information security and privacy is increasingly demanding, with frequent imposition of new and changing requirements. For example, the European Union’s General Data Protection Regulation (“GDPR”), which became effective in May 2018, and other similar U.S. federal and state and foreign laws and regulations in this area, impose significant new requirements and additional obligations for companies on how they collect, process and transfer personal data by enhancing consumer privacy rights and imposing significant fines for non-compliance. The potential for fines and other related costs in the event of a breach of or non-compliance with the GDPR or other existing or proposed information security or privacy laws and requirements may have an adverse effect on our financial results.

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 and technologies, and talent within these categories.

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

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.

Impact of COVID-19

The COVID-19 pandemic has resulted in a significant disruption to the global economy that has and is likely to have continued adverse impact on our business. We have experienced reductions in customer demand in several of our end markets. We expect that social distancing measures, higher employee absenteeism, and reductions in production due to mandated labor capacity restrictions at some of our plants in Asia, Europe, and North America, as well as the reduced operational capacity of our customers and suppliers, could continue to impact our business into 2021. As a result of these economic headwinds, we implemented cost savings measures throughout 2020, some of which were temporary in nature. We continue to evaluate market conditions and the impact on our operations to determine the extent and duration of any future cost measures. The pandemic could lead to additional extended disruptions of economic activity and the impact on our consolidated results of operations, financial position and cash flows could be material. We remain cautious about the financial impact into 2021.

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

CTS CORPORATION 18

Table of Contents

The following table highlights changes in significant components of the Consolidated Statements of Earnings for the years ended December 31, 2020, and December 31, 2019:

Years Ended December 31, Percent of Net Sales

Gain on sale of assets — (63) — — —

Diluted earnings per share:

Diluted net earnings per share $ 1.06 $ 1.09

Net sales were $424,066 for the year ended December 31, 2020, a decrease of $44,933, or 9.6% from 2019. Net sales for 2020 were adversely impacted by lower volumes as a result of the COVID-19 pandemic and government activities to control its spread. Specifically, mandated or selective plant closures due to the pandemic and related government activities drove weak demand in some end markets. In addition, the activities had a significant impact on our supply chain. We remain cautious about possible future disruptions on our supply chain, operations, and future demand.

Net sales to transportation markets decreased $57,559 or 19.3%. Net sales to other markets increased $12,626 or 7.4%. The QTI acquisition, which was completed in July 2019, added sales of $24,508 in 2020 compared to $9,252 in 2019. Changes in foreign exchange rates increased net sales by $1,706 year-over-year primarily due to the U.S. Dollar depreciating compared to the Chinese Renminbi and Euro.

Gross margin as a percent of sales was 32.8% in 2020 versus 33.6% in 2019. The decrease in gross margin was driven primarily by lower sales volumes, which was partially offset by various cost reduction measures.

Selling, general and administrative ("SG&A") expenses were $67,787, or 16.0% of sales for the year ended December 31, 2020, versus $70,408 or 15.0% of sales in the comparable period of 2019. The 2020 SG&A costs include savings from cost reduction measures we implemented during the year, partially offset by a full year of amortization of intangibles and other operating costs associated with the QTI acquisition.

Research and development expenses were $24,317 or 5.7% of sales in 2020 compared to $25,967 or 5.5% of sales in 2019.

Restructuring charges were $1,830 for year ended December 31, 2020 and were primarily as a result of certain initiatives initiated in the third quarter of 2020. The restructuring actions are focused on optimizing our manufacturing footprint and improving operational efficiency by better utilizing our systems capabilities. Restructuring charges were $7,448 in 2019.

Operating earnings were $45,129, or 10.6% of sales in 2020, compared to $53,815, or 11.5% of sales in 2019 as a result of the items discussed above.

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

Years Ended December 31,

Total other income (expense), net $ 350 $ (3,549)

CTS CORPORATION 19

Interest expense increased mainly due to a higher average debt balance during 2020 related to the QTI acquisition and additional borrowings at the end of the first quarter to ensure adequate liquidity for the next several quarters in light of COVID-19 concerns. Interest income declined as a result of lower interest rates on foreign cash balances. The Other income, net for the twelve months ended December 31, 2020 was principally driven by foreign currency translation gains, mainly due to the depreciation of the U.S. Dollar compared to the Chinese Renminbi and Euro, which were partially offset by pension expense.

Years Ended December 31,

The effective income tax rate in 2020 was 23.7% compared to 28.1% in the prior year. This decrease is primarily attributed to the change in the mix of earnings by jurisdiction, decreases in uncertain tax position and offset by the company's decision to no longer reinvest the earnings of its Taiwan subsidiary. The tax rate in 2020 was higher than the U.S. statutory federal tax rate primarily due to foreign earnings that are taxed at higher rates and unfavorable impacts to reserves. The tax rate in 2019 was higher than the U.S. statutory federal tax rate primarily due to foreign earnings that are taxed at higher rates, the impact of taxes on unremitted earnings and unfavorable increases to reserves.

Net earnings were $34,686 or $1.06 per diluted share for the year ended December 31, 2020 compared to earnings of $36,146 or $1.09 per diluted share in the comparable period of 2019.

Liquidity and Capital Resources

Cash and cash equivalents were $91,773 at December 31, 2020, and $100,241 at December 31, 2019, of which $90,051 and $98,309 respectively, were held outside the United States. The decrease in cash and cash equivalents of $8,468 was primarily driven by net payments of long-term debt of $45,100, capital expenditures of $14,858, payments for the SSI acquisition of $8,309, treasury stock purchases of $8,080, and dividends paid of $5,179, which were partially offset by cash generated from operating activities of $76,783. Total debt as of December 31, 2020, and December 31, 2019, was $54,600 and $99,700, respectively. Total debt as a percentage of total capitalization, defined as long-term debt as a percentage of total debt and shareholders’ equity, was 11.4% at December 31, 2020, compared to 19.7% at December 31, 2019.

Working capital decreased by $12,231 from December 31, 2019, to December 31, 2020, driven mainly by the decrease in cash and cash equivalents related to the items noted above.

Cash Flows from Operating Activities

Net cash provided by operating activities was $76,783 during the year ended December 31, 2020. Components of net cash provided by operating activities included net earnings of $34,686, depreciation and amortization expense of $26,670, stock-based compensation of $3,417, other net non-cash items totaling $930, and a net cash inflow from changes in assets and liabilities of $10,064.

Cash Flows from Investing Activities

Net cash used in investing activities for the year ended December 31, 2020 was $23,167, driven by capital expenditures of $14,858 and the payment for the Sensor Scientific, Inc. (“SSI”) acquisition of $8,309. See Note 3 "Business Acquisitions" in the Notes to the Consolidated Financial Statements in this Annual Report on Form 10-K.

Cash Flows from Financing Activities

Net cash used in financing activities for the year ended December 31, 2020, was $61,333. The net cash outflow was the result of net payments of long-term debt of $45,100, treasury stock purchases of $8,080, dividend payments of $5,179, taxes paid on behalf of equity award participants of $1,917, and a contingent consideration payment of $1,057.

Capital Resources

Long-term debt was comprised of the following:

As of December 31,

Standby letters of credit $ 1,740 $ 1,800

Amount available, subject to covenant restrictions $ 243,660 $ 198,500

Weighted-average interest rate 1.92% 3.25%

Commitment fee percentage per annum 0.23% 0.23%

On February 12, 2019, we entered into an amended and restated five-year Credit Agreement with a group of banks (the "Credit Agreement") to extend the term of the facility. The Credit Agreement provides for a revolving credit facility of $300,000, which may be increased by $150,000 at the request of the Company, subject to the administrative agent's approval. This new unsecured credit facility replaces the prior $300,000 unsecured credit facility, which would have expired August 10, 2020. Borrowings of $50,000 under the prior credit agreement were refinanced into the Credit Agreement. The prior agreement was terminated as of February 12, 2019.

The Revolving Credit Facility includes a swing line sublimit of $15,000 and a letter of credit sublimit of $10,000. Borrowings under the Revolving Credit Facility bear interest at the base rate defined in the Credit Agreement. We also pay a quarterly commitment fee on the unused portion of the Revolving Credit Facility. The commitment fee ranges from 0.20% to 0.30% based on our total leverage ratio.

We have entered into interest rate swap agreements to fix interest rates on $50,000 of long-term debt through February 2024. The difference to be paid or received under the terms of the swap agreements is recognized as an adjustment to interest expense when settled.

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. 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, and debt service requirements for at least the next twelve months. However, we may choose to pursue additional equity and debt financing to provide additional liquidity or to fund acquisitions.

Critical Accounting Policies and Estimates

Management prepared the consolidated financial statements under accounting principles generally accepted in the United States of America. These principles require the use of estimates, judgments, and assumptions. We believe that the estimates, judgments, and assumptions we used are reasonable, based upon the information available.

Our estimates and assumptions affect the reported amounts in our financial statements. The following accounting policies comprise those that we believe are the most critical in understanding and evaluating our reported financial results.

Revenue Recognition

Product revenue is recognized when the transfer of promised goods to a customer occurs in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods. 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; 5) recognize revenue when (or as) the entity satisfies a performance obligation.

Product Warranties

Provisions for estimated warranty expenses primarily related to our automotive products are made at the time products are sold. These estimates are established either using a quoted industry rate or 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 0.5% to 2.4% of total 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.

CTS CORPORATION 21

Accounts Receivable

We have standardized credit granting and review policies and procedures for all customer accounts, including:

• Credit reviews of all new significant customer accounts,

• Ongoing credit evaluations of current customers,

• Credit limits and payment terms based on available credit information,

• Adjustments to credit limits based upon payment history and the customer's current creditworthiness,

• An active collection effort by regional credit functions, reporting directly to the corporate financial officers, and

• Limited credit insurance on the majority of our international receivables.

We reserve for estimated credit losses based on 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. Over the last three years, accounts receivable reserves have ranged from 0.1% to 1.1% of total accounts receivable. We believe our reserve level is appropriate considering the quality of the portfolio. While credit losses have historically been within expectations of the reserves established, we cannot guarantee that our credit loss experience will continue to be consistent with historical experience or our current forecasts.

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 forecasts of product demand and production requirements.

Over the last three years, our reserves for excess and obsolete inventories have ranged from 10.2% to 13.9% of gross inventory. We believe our reserve level is appropriate considering the quantities and quality of the inventories.

Retirement Plans

Actuarial assumptions are used in determining pension income and expense and our defined benefit obligations. We utilize actuaries from consulting companies in each applicable country to develop our discount rates, matching high-quality bonds currently available and expected to be available during the period to maturity of the pension benefit in order to provide the necessary future cash flows to pay the accumulated benefits when due. After considering the recommendations of our actuaries, we have assumed a discount rate, expected rate of return on plan assets, and a rate of compensation increase in determining our annual pension income and expense and the projected benefit obligation. During the fourth quarter of each year, we review our actuarial assumptions in light of current economic factors to determine if the assumptions need to be adjusted. Changes in the actuarial assumptions could have a material effect on our results of operations.

In February 2020, the CTS Board of Directors authorized management to explore termination of our U.S. Pension Plan (“Plan”) at management's discretion, subject to certain conditions. On June 1, 2020, we amended the Plan whereby we set an effective termination date of July 31, 2020. In February 2021, we received the determination letter from the Internal Revenue Service that allows us to proceed with the termination process. The completion of the Plan termination process, including offering lump sum settlements and the final purchases of annuities, is expected to occur in 2021. Since the amount of the settlement depends on a number of factors determined as of the liquidation date, including lump sum payout estimates, the annuity pricing interest rate environment and asset experience, we are currently unable to determine the ultimate cost of the settlement. However, we expect non-cash settlement charges of approximately $10,000 to $20,000 to be recognized in the second or third quarter of 2021 with the remaining amount of the gross accumulated other comprehensive loss balance to be recognized by the end of 2021. We do not expect any cash contributions from the Company to the Plan as a result of this termination because plan assets significantly exceed estimated liabilities.

Impairment of Goodwill

Goodwill of a reporting unit is tested for impairment annually, 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,

CTS CORPORATION 22

Table of Contents

• 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 of the above indicators of impairment have occurred, we perform an impairment test. We have the option to perform a qualitative assessment (commonly referred to as "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.

We typically perform a quantitative assessment at least every three years, or as conditions require. Our previous quantitative test was in 2017, therefore, we performed the current year assessment using a quantitative approach. Based upon our latest assessment, we determined that our goodwill was not impaired as of October 1, 2020.We will monitor future results and will perform a test if indicators trigger an impairment review.

Impairment of Other Intangible and 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,

• 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. We recorded a charge of $1,016 during the first quarter due to the impairment of a specific asset group. In addition, we recorded a charge of $2,200 during the third quarter of 2020 due to the impairment of a specific asset group as a result of the restructuring actions being taken. No other indicators of impairment were identified during the year ended December 31, 2020.

Environmental and Legal 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. Significant judgment is required to determine the existence and amounts of our environmental, legal and other contingent liabilities. We regularly consult with attorneys and consultants to determine the relevant facts and circumstances before we record a liability. Changes in laws, regulatory orders, cost estimates, participation of other parties, timing of payments, input of attorneys and consultants, or other circumstances may have a material impact on the recorded liability.

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 consolidated income tax expense.

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 jurisdiction 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.

CTS CORPORATION 23

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) No. 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.

Our practice is to recognize interest and penalties related to income tax matters as part of income tax expense.

Following the enactment of the 2017 Tax Cut and Jobs Act and the associated one-time transition tax, in general, repatriation of foreign earnings to the U.S. can be completed with no incremental U.S. Tax. However, there are limited other taxes that continue to apply such as foreign withholding and certain state taxes. The company records a deferred liability for the estimated foreign earnings and state tax cost associated with the undistributed foreign earnings that are not permanently reinvested.

Contractual Obligations

Our contractual obligations as of December 31, 2020, were:

Payments due by period

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.

Management believes that existing capital resources and funds generated from operations are sufficient to finance anticipated capital requirements.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk

(in thousands)

Our cash flows and earnings are subject to fluctuations resulting from changes in foreign currency exchange rates and interest rates. 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.

Interest Rate Risk

We are exposed to risk of changes in interest rates on our revolving credit facility. There was $54,600 and $99,700 outstanding under our revolving credit facility at December 31, 2020, and 2019, respectively. As of December 31, 2020, we had interest rate swaps that fix interest costs on $50,000 of our long-term debt through February 2024.

Foreign Currency Risk

We are exposed to foreign currency exchange rate risks. Our significant foreign subsidiaries are located in China, Czech Republic, Mexico, and Taiwan. As of December 31, 2020, we had foreign currency forward contracts outstanding with a notional value of $14,958 to hedge our exposure against the Mexican Peso.

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 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

CTS CORPORATION 24

Table of Contents

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.

Public Health Risk

The COVID-19 outbreak is adversely affecting our business. We and some of our suppliers and customers have facilities that were required to remain closed for a period of time, and when permitted to reopen, employees have been limited in their ability to return to work due to governmental restrictions. The consequences of the outbreak, and the actions taken to limit its spread, have adversely affected our sales and results of operations in 2020 and could impact our results in 2021, and possibly longer if coronavirus consequences continue.

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, 2020 and 2019, the related consolidated statements of earnings, comprehensive earnings, changes in shareholders’ equity, and cash flows for each of the three years in the period ended December 31, 2020, and the related notes and financial statement schedules included under Item 15(a) (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2020 and 2019, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2020, 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, 2020, 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 25, 2021 expressed an unqualified opinion.

Basis for opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s 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 supporting 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 matter

The critical audit matter communicated below is a matter arising from the current period audit of the financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the financial statements; and (2) involved our especially challenging, subjective, or complex judgments. The communication of a critical audit matter 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 matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Goodwill impairment assessment

The Company’s consolidated goodwill balance was $109.5 million as of December 31, 2020. 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 and performed a quantitative impairment assessment as of October 1, 2020 for each of its three reporting units. The quantitative impairment assessment involves the comparison of the fair value of a reporting unit to its carrying amount. The Company determines the fair value of each reporting unit using a combination of discounted cash flow analysis and market-based valuation methodologies, 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 impairment assessment is a critical matter was the significant auditor judgment required to evaluate the reporting units’ forecasted revenues, forecasted cash flows over a multi-year period, discount rates, and estimated valuation multiples.

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

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 cashflows 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, information technology, medical, telecommunications, 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. The allowance for credit losses is based on management's estimates of the collectability of its accounts receivable after analyzing historical credit losses, customer concentrations, customer creditworthiness, current economic trends, specific customer collection issues, and reasonable and supportable forecasts that affect the collectability of the remaining cashflows over the contractual terms of our receivables. Uncollectible trade receivables are charged against the allowance for credit losses when all reasonable efforts to collect the amounts due have been exhausted.

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

Years Ended December 31,

We sell parts to these three transportation customers for certain vehicle platforms under purchase agreements that have no volume commitments and are subject to purchase orders issued on a periodic basis.

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 or the net realizable value using the first-in, first-out ("FIFO") method. We review inventory quantities on hand and record a provision for excess and obsolete inventory based on forecasts of product demand and production requirements.

Retirement Plans: We have various defined benefit and defined contribution retirement plans. Our policy is to annually fund the defined benefit pension plans at or above the minimum required by law. We: 1) recognize the funded status of a benefit plan (measured as the difference between plan assets at fair value and the projected benefit obligation) in our Consolidated Balance Sheets; 2) recognize the gains or losses and prior service costs or credits that arise during the period but are not recognized as components of

CTS CORPORATION 33

net periodic benefit/cost as a component of other comprehensive earnings; and 3) measure defined benefit plan assets and obligations as of the date of our fiscal year-end.

During 2020, the Company commenced the termination process on our primary U.S. Pension Plan (“U.S. Plan”) and expects to offer employees a lump sum settlement and then complete the transfer of any remaining U.S. Plan assets to a third-party administrator, which the Company expects to complete by the end of 2021. See Note 7, "Retirement Plans" for further information.

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 3 to 15 years, and software from 2 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.

We have the option to perform a qualitative assessment (commonly referred to as "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.

We typically perform a quantitative assessment at least every three years, or as conditions require. Our previous quantitative test was in 2017, therefore, we performed the current year assessment using a quantitative approach. Based upon our latest assessment, we determined that our goodwill was not impaired as of October 1, 2020.

In addition to goodwill, we also have acquired in-process research and development ("IPR&D") intangible assets that are treated as indefinite-lived intangible assets and therefore not subject to amortization until the completion or abandonment of the associated research and development efforts. If these efforts are abandoned in the future, the carrying value of the IPR&D asset will be expensed. If the research and development efforts are successfully completed, the IPR&D will be reclassified as a finite-lived asset and amortized over its useful life. In the third quarter of 2020, due to the restructuring actions further outlined in Note 9, we identified a triggering event associated with a specific asset group including IPR&D due to executed restructuring actions. This resulted in the

CTS CORPORATION 34

Table of Contents

recognition of $2,200 of impairment charges, and a revaluation of associated contingent liabilities totaling $1,900. The net impact of $300 was recorded as restructuring charges in the Consolidated Statements of Earnings.

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. We recorded a charge of $1,016 during the first quarter due to the impairment of a specific asset group that was recorded in selling, general and administrative expenses in the Consolidated Statements of Earnings.

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 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. 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; 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 such 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 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, 2020, and 2019:

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 financial instruments as follows:

CTS CORPORATION 35

Instrument Method for determining fair value

Debt Issuance Costs: We have debt issuance costs related to our long-term debt that are being amortized using the straight-line method over the life of the debt.

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, performance share units ("PSU's"), and stock options, in the Consolidated Statements of Earnings.

We estimate the fair value of stock option awards on the date of grant using the Black-Scholes option pricing model. A number of assumptions are used by the Black-Scholes option pricing model to compute the grant date fair value of an award, including expected price volatility, option term, risk-free interest rate, and dividend yield. These assumptions are established at each grant date based upon current information at that time. Expected volatilities are based on historical volatilities of CTS' common stock. The expected option term is derived from historical data of exercise behavior. Actual option terms can differ from the expected option terms as a result of different groups of employees exhibiting different exercise behavior. The dividend yield is based on historical dividend payments. The risk-free rate for periods within the contractual life of the option is based on the U.S. Treasury yield curve at the time of grant. The fair value of awards that are ultimately expected to vest is recognized as expense over the requisite service periods of the awards 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. The grant date fair value of our market-based RSUs is determined by using a simulation, or Monte Carlo, approach. Under this approach, stock returns from a comparative group of companies are simulated over the performance period, considering both stock price volatility and the correlation of returns. The simulated results are then used to estimate the future payout based on the performance and payout relationship established by the conditions of the award. The future payout is discounted to the measurement date using the risk-free interest rate.

Both our stock option and 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 portion 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.

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.

Our antidilutive securities consist of the following:

Years Ended December 31,

Foreign Currencies: The financial statements of our non-U.S. subsidiaries, except the United Kingdom ("U.K.") subsidiary, 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 Statement of Earnings includes the following:

Years Ended December 31,

The assets and liabilities of our U.K. subsidiary 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 loss" component of shareholders' equity. Our Consolidated Statement 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.

Reclassifications: Certain reclassifications have been made to prior year amounts to conform to the current year presentation. The reclassifications had no impact on previously reported net earnings.

Accounting Pronouncements Recently Adopted

ASU No. 2018-14 "Compensation - Retirement Benefits - Defined Benefit Plans - General"

In August 2018, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2018-14, "Compensation - Retirement Benefits - Defined Benefit Plans - General." This ASU modifies the disclosure requirements for defined benefit and other postretirement plans. This ASU eliminates certain disclosures associated with accumulated other comprehensive income, plan assets, related parties, and the effects of interest rate basis point changes on assumed health care costs; while other disclosures have been added to address significant gains and losses related to changes in benefit obligations. This ASU also clarifies disclosure requirements for projected benefit and accumulated benefit obligations. The amendments in this ASU are effective for fiscal years ending after December 15, 2020 and for interim periods therein with early adoption permitted. Adoption on a retrospective basis for all periods presented is required. We have applied the requirements of this ASU to the financial statements.

ASU No. 2018-13 "Fair Value Measurement (Topic 820): Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement"

In August 2018, the FASB issued ASU No. 2018-13 "Fair Value Measurement (Topic 820): Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement". This ASU modified the disclosures related to recurring and nonrecurring fair value measurements. Disclosures related to the transfer of assets between Level 1 and Level 2 hierarchies have been eliminated and various additional disclosures related to Level 3 fair value measurements have been added, modified or removed. This ASU is effective for annual periods beginning after December 15, 2019, and interim periods within those fiscal years. Early adoption is permitted upon issuance of the standard for disclosures modified or removed with a delay of adoption of the additional disclosures until their effective date. We adopted this ASU on January 1, 2020 and it did not have a material impact on our financial statements.

ASU No. 2016-16 "Income Taxes (Topic 740) Intra-Entity Transfers of Assets Other Than Inventory"

In October 2016, the FASB issued ASU No. 2016-16, "Intra-Entity Transfers of Assets Other Than Inventory". This ASU is meant to improve the accounting for the income tax effect of intra-entity transfers of assets other than inventory. Currently, U.S. GAAP prohibits the recognition of current and deferred income taxes for intra-entity asset transfers until the asset is sold to a third party. This ASU will now require companies to recognize the income tax effect of an intra-entity asset transfer (other than inventory) when the transaction occurs. This ASU is effective for public companies, for fiscal years beginning after December 15, 2019 and interim periods within those annual reporting periods. Early adoption is permitted and is to be applied on a modified retrospective basis through a cumulative-effect adjustment to retained earnings as of the beginning of the period of adoption. We adopted this ASU on January 1, 2020 and it did not have a material impact on our financial statements.

ASU 2016-13 "Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments"

In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which amends the current accounting guidance and requires the measurement of all expected losses based on historical experience, current conditions and reasonable and supportable forecasts. For trade receivables, loans, and other financial

CTS CORPORATION 37

instruments, we will be required to use a forward-looking expected loss model rather than the incurred loss model for recognizing credit losses which reflects losses that are probable. The standard will become effective for interim and annual periods beginning after December 15, 2019, with early adoption permitted. Application of the amendments is through a cumulative-effect adjustment to retained earnings as of the effective date. We adopted this ASU on January 1, 2020 and it did not have a material impact on our financial statements.

Recently Issued Accounting Pronouncements

ASU No. 2020-04 "Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting"

In March 2020, the FASB issued ASU 2020-04, “Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting”, which provides temporary optional guidance for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting as it relates to our LIBOR indexed instruments. ASU 2020-04 provides optional expedients and exceptions for applying U.S. GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. ASU 2020-04 is effective for all entities as of March 12, 2020 through December 31, 2022, and an entity may elect to apply ASU 2020-04 for contract modifications by Topic or Industry Subtopic as of any date from the beginning of an interim period that includes or is subsequent to March 12, 2020, or prospectively from a date within an interim period that includes or is subsequent to March 12, 2020, up to the date that the financial statements are available to be issued. We are currently evaluating the impact of the transition from LIBOR to alternative reference interest rate in our financial instruments. Our LIBOR based credit facility includes a provision for the determination of a successor LIBOR rate, and we are still evaluating the impact to potential future hedging activities.

ASU No. 2019-12 "Simplifying the Accounting for Income Taxes"

In December 2019, the FASB issued ASU 2019-12, Simplifying the Accounting for Income Taxes, as part of its Simplification Initiative to reduce the cost and complexity in accounting for income taxes. ASU 2019-12 removes certain exceptions related to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an interim period, and the recognition of deferred tax liabilities for outside basis differences. ASU 2019-12 also amends other aspects of the guidance to help simplify and promote consistent application of GAAP. The guidance is effective for interim and annual periods beginning after December 15, 2020, with early adoption permitted. We do not expect the adoption of this ASU to have a material impact on our financial statements or results.
