The Company regularly applies for patent protection on such new products. While, in the aggregate, the Company’s patents are important in the operation of its businesses, the Company believes that the loss by expiration or otherwise of any one patent or group of patents would not materially affect its business. MANUFACTURING The Company’s manufacturing facilities are in China, Germany, Italy, Japan, Lithuania, Mexico, Philippines, Portugal, the U.K., and the U.S. The Company performs the majority of its own fabrication and maintains in-house capabilities for metal stamping, surface mount assembly, plating (silver, nickel, zinc, and oxides) and thermoplastic molding. In addition, the Company fabricates semiconductor wafers for certain applications and maintains in-house capability for epitaxy fabrication, die attach, and wafer probe testing. After sub-components are readied for assembly, final assembly is accomplished on fully automatic and semi-automatic assembly machines. Quality assurance and operations personnel, using techniques such as statistical process control, perform tests, checks and measurements during the production process to maintain the highest levels of product quality, including safety and reliability, and customer satisfaction. Additionally, the Company utilizes external wafer foundries and subcontracted test and assembly facilities for a portion of its semiconductor business. The principal raw materials for the Company’s products include copper and copper alloys, resin and heat-resistant plastics, zinc, melamine, glass, silver, gold, raw silicon, solder, rubber, and various gases. The Company’s strategy is to prequalify suppliers for quality assurance and supply continuity, and when possible, to localize supply sources close to its manufacturing sites. This helps to minimize the transportation of materials, and ultimately reduces the Company’s environmental footprint by decreasing emissions, consistent with its sustainability strategy. For critical materials, the Company looks to diversify its supplier base by prequalifying second sources. SALES AND MARKETING The Company goes to market through selling organizations consisting of worldwide direct sales personnel, distribution partners and manufacturers’ representatives. The direct sales force closely works with global OEM, Tier One automotive, consulting engineers, and major end customers to design-in and sell all of the Company’s products. The distributors provide fulfillment for a majority of customers including those partnered with electronic manufacturing services ("EMS"). The Company has sales offices and direct sales channels in a number of countries around the world. Electronics Segment 7 Our Electronics segment products are used across a variety of applications. While certain of our products require less design support for our customers, many of our products are incorporated into applications with complex design technical support requirements. Most Electronics segment products are sold through our direct salesforce or through our channel distribution partners. The fulfillment of these products is primarily through our broad line distribution partners, including global distributors such as Arrow Electronics, Inc., Future Electronics and TTI, Inc., regional and high service distributors, including Digi-Key and Mouser, as well as directly to OEM's. Transportation Segment The Company primarily uses a direct sales force to service all of the major automotive and commercial vehicle OEMs, system suppliers, and Tier One automotive and aftermarket customers globally. In selected areas, the Company also uses distributors to service smaller customers and to provide supply chain fulfillment for certain customers. The Company also leverages its transportation customer relationships to sell products from the Electronics segment into transportation end markets, primarily to Tier One automotive customers. These revenues are reported in the Electronics segment. Industrial Segment The Company markets and sells its Industrial segment products direct to OEMs, and through electrical distributors and electronics distribution channels to various end customers including electrical contractors, factories, municipalities, and utilities. CUSTOMERS The Company directly sells to over 6,900 customers and distributors worldwide. Sales to Arrow Electronics, Inc., which were reported in our Electronics, Transportation and Industrial segments, were 10.7%, 10.4% and 10.7% of consolidated net sales in 2021, 2020, and 2019, respectively. No other single customer accounted for more than 10% of net sales during any of the last three years. During fiscal 2021, 2020, and 2019, net sales to customers outside the U.S. accounted for approximately 69%, 73%, and 71%, respectively, of the Company’s total net sales. CYBERSECURITY The Company relies on its information technology systems and networks in connection with many of its business activities. Some of these networks and systems are managed directly by the Company, while others are managed by third-party service providers and are not under the Company's day-to-day control. We oversee the services provided by the third-party service providers. We continually evaluate ourselves for appropriate business continuity and disaster recovery planning, with test scenarios that include simulations and penetration tests. Our networks are monitored by intrusion detection services, and our systems and applications are routinely tested for vulnerabilities and are operated with an appropriate patch management program. We employ a skilled IT workforce to implement our cybersecurity programs and to handle specific security responsibilities. Our IT workforce is trained to address security and compliance-related issues as they arise. COMPETITION The Company’s products compete with similar products of other manufacturers, some of which may have substantially greater financial resources than the Company. In the Electronics segment, the Company’s competitors include Eaton Corporation, Bourns Inc., TDK, ON Semiconductor Corporation, Infineon Technologies, STMicroelectronics NV, Semtech Corporation, and Vishay Intertechnology Inc. In the Transportation segment, the Company’s competitors include Eaton Corporation, Pacific Engineering, MTA (Meccanotecnica Codognese), CTS Corporation, Amphenol Corporation, Sensata Technologies Holding NV, and TE Connectivity Ltd. In the Industrial segment, the Company’s major competitors include Eaton Corporation, GE Multilin, and Mersen. The Company believes that it globally competes on the basis of innovative products, the breadth of its product line, the quality, design and performance of its products based on their reliability, consistency and safety, its technical capabilities and application expertise, and the responsiveness of its customer service. BACKLOG The backlog of unfilled orders at January 1, 2022 was approximately $1,657.1 million, compared to $709.9 million at December 26, 2020 with the increase primarily driven by all segments and acquisition. Substantially all the orders currently in backlog are scheduled for delivery in 2022. 8 HUMAN CAPITAL MANAGEMENT A passion for engineering excellence and an innovative spirit have been a part of what it means to work at Littelfuse since its founding in 1927.

The Company further supports the mental and physical well-being of the Company's employees through a range of wellness programs that promote a healthy lifestyle. During the COVID-19 pandemic, the Company has prioritized the health and safety of its associates and their families. In an effort to protect the health and safety of our associates, the Company has taken proactive steps in our facilities globally to implement safety procedures including hygiene and disinfection protocols, social distancing, and providing transportation alternatives for employees to get to work and personal protective equipment. Community Involvement The Company encourages and sponsors employees to donate their time and other resources to improve the communities where they live and work. The Company's teams around the globe regularly engage in local community outreach, sponsoring activities and initiatives that align with its overall community involvement strategy. The causes the Company supports include science, technology, engineering and mathematics ("STEM") education, community improvement and environmental stewardship. SUSTAINABILITY The Company is focused on creating long-term value for customers, employees, investors, and the communities where they live and work through sustainable business practices. Many of the Company's key end markets are linked to sustainable applications such as electric vehicles and charging infrastructure, renewable energy, and power management. Sustainable end markets have been a focus of the Company for decades and the Company published its first Sustainability Report in 2021, as the Company aims to further communicate its commitment and progress towards key internal sustainability initiatives. The initial focus areas in the Company's Sustainability Report include: • • • • business ethics training, education, and career development health and safety in the workplace economic performance • • • • innovation water and wastewater management diversity and equal opportunity energy management • • • • climate change and greenhouse gas emissions sustainable supply chain community involvement waste and hazardous material management Additional information on how the Company manages each of these topics and the sustainability program progress is available in the Company's Sustainability Report, located on the Company's website at https://www.littelfuse.com/about-us/ sustainability.aspx. The contents of the Company's Sustainability Report and website are not incorporated by reference in this Annual Report on Form 10-K. ENVIRONMENTAL REGULATION 10 The Company is subject to numerous foreign, federal, state, and local regulations relating to air and water quality, the disposal of hazardous waste materials, safety and health. Compliance with applicable environmental regulations has not significantly changed the Company’s competitive position, capital spending or earnings in the past and the Company does not presently anticipate that compliance with such regulations will change its competitive position, capital spending or earnings for the foreseeable future. The Company believes that it is currently in compliance in all material respects with applicable environmental laws and regulations. Littelfuse GmbH, which was acquired by the Company in May 2004, is responsible for maintaining closed coal mines in Germany from legacy operations. The Company is compliant with German regulations pertaining to the maintenance of the mines and has an accrual related to certain of these coal mine shafts based on an engineering study estimating the cost of remediating the dangers (such as a shaft collapse) of certain of these closed coal mine shafts in Germany. The accrual is reviewed annually and calculated based upon the estimated costs of remediating the shafts. Further information regarding the coal mine liability accrual is provided in Note 1, Summary of Significant Accounting Policies and Other Information, of the Notes to Consolidated Financial Statements included in this Annual Report. ITEM 1A. RISK FACTORS. The Company’s business, financial condition, and results of operations are subject to various risks and uncertainties, including the risk factors it has identified below. Any of the following risk factors could materially and adversely affect the Company’s business, financial condition, or results of operations. These factors are not necessarily listed in order of importance. 1) Operational Risks: The Company’s industry is subject to intense competitive pressures. The Company operates in markets that are highly competitive. The Company competes on the basis of price, product performance and quality, service, and / or brand name across the industries and markets it serves. Competitive pressures could affect the prices the Company is able to charge its customers or demand for its products. The Company may not always be able to compete on price, particularly when compared to manufacturers with lower cost structures. Some of the Company’s competitors have substantially greater sales, financial and manufacturing resources and may have greater access to capital than the Company. As other companies enter its markets or develop new products, competition may further intensify. The Company’s failure to compete effectively could materially adversely affect its business, financial condition, and results of operations. The Company engages in strategic acquisitions and may not realize the anticipated benefits of the acquisitions and / or may encounter difficulties in integrating these businesses. The Company seeks to grow through strategic acquisitions. In the past, the Company has acquired a number of businesses or companies and additional product lines and assets. The Company intends to continue to expand and diversify its operations with additional future acquisitions. An acquired business, technology, service or product could under-perform relative to the Company’s expectations and the price paid for it, or not perform in accordance with the Company’s anticipated timetable. This could cause the Company’s financial results to differ from expectations in any given fiscal period, or over the long term. The success of these transactions also depends on the Company’s ability to integrate the assets, operations, and personnel associated with these acquisitions. The Company may encounter difficulties in integrating acquisitions with the Company’s operations and may not realize the degree or timing of the benefits that are anticipated from an acquisition. The Company may also discover liabilities or deficiencies associated with the companies or assets it acquires that were not identified in advance, which may result in significant unanticipated costs. The effectiveness of the Company’s due diligence review and its ability to evaluate the results of such due diligence are dependent upon the accuracy and completeness of statements and disclosures made or actions taken by the companies acquired or their representatives, as well as the limited amount of time in which acquisitions are executed. In addition, the Company may fail to accurately forecast the financial impact of an acquisition transaction, including tax and accounting charges. Acquisitions may also result in recording of significant additional expenses to the results of operations and recording of substantial intangible assets on the balance sheet upon closing. Any of these factors may adversely affect the Company’s financial condition and results of operations. 11 Disruptions in the Company’s manufacturing, supply or distribution chain could result in an adverse impact on results of operations. The Company sources materials and sells product through various global network channels. A disruption could occur within the Company’s manufacturing, distribution or supply chain network. This could include damage or destruction due to various causes including natural disasters or political instability which would cause one or more of these network channels to become non-operational. This could adversely affect the Company’s ability to manufacture or deliver its products in a timely manner, impair its ability to meet customer demand for products and result in lost sales or damage to its reputation. Such a disruption could have a material adverse effect on the Company’s business, financial condition and results of operations. The Company may be unable to manufacture and deliver products in a manner that is responsive to its customers’ needs. The end markets for the Company’s 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 its existing products obsolete and unmarketable before it can recover any or all of its research, development, and commercialization expenses on capital investments. Furthermore, the life cycles of its products may change and are difficult to estimate. The Company’s future success will depend upon its ability to manufacture and deliver products in a manner that is responsive to its customers’ needs. The Company will need to develop and introduce new products and product enhancements on a timely basis that keep pace with technological developments and emerging industry standards and address increasingly sophisticated requirements of its customers. The Company invests heavily in research and development without knowing if it will recover these costs. The Company’s competitors may develop products or technologies that will render its products non-competitive or obsolete. If it cannot develop and market new products or product enhancements in a timely and cost-effective manner, its business, financial condition and results of operations could be materially adversely affected. The Company’s business may be interrupted by labor disputes or other interruptions of supplies. A work stoppage could occur at certain Company facilities, most likely as a result of disputes under collective bargaining agreements or in connection with negotiations of new collective bargaining agreements. In addition, the Company may experience a shortage of supplies for various reasons, such as financial distress, work stoppages, natural disasters, or production difficulties that may affect one of its suppliers. A significant work stoppage, or an interruption or shortage of supplies for any reason, if protracted, could substantially adversely affect the Company’s business, financial condition and results of operations. Failure to attract and retain qualified personnel could affect the Company’s business results. The Company’s success in its existing and acquired businesses, depends on the Company’s ability to attract, retain, and motivate a highly-skilled and diverse management team and workforce. Failure to ensure that the Company has the depth and breadth of personnel with the necessary skill set and experience could impede its ability to deliver growth objectives and execute the Company’s strategy. Competition for qualified employees among companies that rely heavily upon engineering and technology is at times intense, and the loss of qualified employees could hinder the Company’s ability to conduct research activities successfully and develop marketable products. The Company may not be successful protecting its intellectual property. The Company considers its intellectual property, including patents, trade names, and trademarks, to be of significant value to its business as a whole. The Company’s products are manufactured, marketed, and sold under a portfolio of patents, trademarks, licenses, and other forms of intellectual property, some of which expire or are allowed to lapse at various dates in the future. The Company develops and acquires new intellectual property on an ongoing basis and considers all of its intellectual property to be valuable. The Company's policy is to file applications and obtain patents for the great majority of its novel and innovative new products including product modifications and improvements. Based on the broad scope of its product lines, the Company believes that the loss or expiration of any single intellectual property right would not have a material adverse effect upon its consolidated results of operations, financial position and cash flows; however, multiple losses or expirations could have a material adverse effect upon the Company’s consolidated results of operations, financial position and cash flows. 2) Regulatory Risks: 12 Climate change, and the regulatory and legislative developments related to climate change, may have a material adverse impact on our business and results of operations. The potential physical impacts of climate change on our business operations are highly uncertain and differ in each geographic region where we operate. These impacts may include changes in weather patterns and increased weather intensity, water shortages, changing sea levels and changing temperatures. The impacts of climate change may materially and adversely impact the cost of production, insurance availability, and financial performance of our operations. Further, any impacts to our business and financial condition as a result of climate change are likely to occur over a sustained period of time and are therefore difficult to quantify with any degree of specificity. For example, extreme weather events may result in adverse physical effects on portions of our or others infrastructure, which could disrupt our supply chain and our customers and ultimately our business operations. In addition, disruption of transportation and distribution systems could result in reduced operational efficiency and customer service interruption. Climate-related events have the potential to disrupt our business, including the business of our suppliers and customers, and may cause us to experience higher attrition, and additional costs to resume operations. Increased government or governmental bodies contemplating legislative and regulatory changes in response to the potential impact of climate change could impose significant costs on us and our suppliers and customers, including increased cost of materials and natural resources, sources and supply of energy, capital equipment, environmental monitoring and reporting, or other costs to comply with such regulations. Potential regulations or standards could mandate more restrictive manufacturing requirements, such as stricter limits on greenhouse gas emissions and material used in production. Any future climate change regulations could also adversely impact our ability to compete with companies not subject to such regulations. Changes in U.S. and other countries trade policy, including the imposition of tariffs and the resulting consequences, may have a material adverse impact on our business and results of operations. In the past several years, the U.S. government adopted a new approach to trade policy and in some cases to renegotiate, or potentially terminate, certain existing bilateral or multi-lateral trade agreements. It also imposed tariffs on certain foreign goods and products. These measures may materially increase costs for goods imported into the U.S. This in turn could require us to materially increase prices to our customers which may reduce demand, or, if we do not or are unable to increase prices, could result in lower margins on products sold. Changes in U.S. trade policy have resulted in, and could result in more, U.S. trading partners adopting responsive trade policies making it more difficult or costly for us to export our products to those countries. Additionally, continued geo-political issues may result in customers in China seeking to source products from local suppliers, which could result in lower sales or lost customers. The Company is exposed to political, economic, and other risks that arise from operating a multinational business. The Company's customers, suppliers, employees and operations are located in numerous countries around the world, and contribute significantly to its revenues and earnings. Sales to customers outside the U.S. constituted approximately 69% of the Company's net sales in fiscal 2021. Many of the Company's key customers are located outside of U.S. and maintain global operations. Serving a global customer base and remaining competitive in the global marketplace requires the Company to diversify its operations outside the U.S. to capitalize on customer and market opportunities, build a global workforce and maintain a cost efficient structure. In addition, the Company sources a significant amount of raw materials, components and finished goods from third-party suppliers and contract manufacturers. The Company’s operating activities are subject to a number of risks generally associated with multi-national operations, including risks relating to the following: • • • • • • • • • • • • • • general economic conditions; currency fluctuations and exchange restrictions; import and export duties and restrictions; the imposition of tariffs and other import or export barriers; compliance with regulations governing import and export activities; current and changing regulatory requirements; political and economic instability; potentially adverse income tax consequences; transportation delays and interruptions; labor unrest; natural disasters; terrorist activities; public health concerns, including the outbreak of the coronavirus or other pandemics; difficulties in staffing and managing multi-national operations; and 13 • limitations on the Company’s ability to enforce legal rights and remedies. Any of these factors could have a material adverse effect on the Company’s consolidated results of operations, financial position and cash flows. The COVID-19 pandemic could have a material adverse effect on our ability to operate, results of operations, financial condition, liquidity, and capital investments. The World Health Organization declared the COVID-19 outbreak a pandemic in 2020, and the virus continues to spread in areas where we operate and sell our products. The COVID-19 pandemic and similar situations/circumstances in the future could have a material adverse effect on our ability to operate, results of operations, financial condition, liquidity, and capital investments. Several public health organizations have recommended, and some local governments have implemented, certain measures to slow and limit the transmission of the virus, including travel restrictions, shelter-in-place requirements and social distancing requirements. Such preventive measures, or others we may voluntarily put in place, may have a material adverse effect on our business for an indefinite period of time, such as the potential shut down of certain locations, decreased employee availability, potential increased vulnerability to cybersecurity incidents, including breaches of information systems security due to widespread remote working arrangements, potential border closures. Our suppliers and customers, including OEMs and distribution partners, may also face similar disruptions to their operations, which could lead to a disruption in our supply chain as well as decreased demand for our products. These issues may also materially affect our future access to our sources of liquidity, particularly our cash flows from operations, financial condition, capitalization, and capital investments. These disruptions may continue to occur and may result in future impairment, restructuring and other charges. To the extent the COVID-19 pandemic adversely affects our business and financial results, it may also have the effect of heightening many of the other risks described in the risk factors disclosed in Part I, Item 1A. Risk Factors, including those relating to our products and services, financial performance, debt covenant compliance and debt obligations. The ultimate magnitude of COVID-19, including the extent of its impact on our financial and operational results, which could be material, will be determined by the length of time that the pandemic continues, its effect on the demand for our services, as well as the effect of governmental regulations imposed in response to the pandemic. We cannot at this time predict the impact of the COVID-19 pandemic, but it could have a material adverse effect on our business, financial condition, results of operations and/or cash flows. Environmental liabilities could adversely impact the Company’s financial position. Foreign, federal, state and local laws and regulations impose various restrictions and controls on the discharge of materials, chemicals and gases used in the Company’s manufacturing processes or in its finished goods. These environmental regulations have required the Company to expend a portion of its resources and capital on relevant compliance programs. Under these laws and regulations, the Company could be held financially responsible for remedial measures if its current or former properties are contaminated or if it sends waste to a landfill or recycling facility that becomes contaminated, even if the Company did not cause the contamination. The Company may be subject to additional common law claims if it releases substances that damage or harm third parties. In addition, future changes in environmental laws or regulations may require additional investments in capital equipment or the implementation of additional compliance programs. Any failure to comply with new or existing environmental laws or regulations could subject the Company to significant liabilities and could have a material adverse effect on its consolidated results of operations, financial position and cash flows. In the conduct of manufacturing operations, the Company has handled and does handle materials that are considered hazardous, toxic or volatile under federal, state, and local laws. The risk of accidental release of such materials cannot be completely eliminated. In addition, the Company operates or owns facilities located on or near real property that was formerly owned and operated by others. Certain of these properties were used in ways that involved hazardous materials. Contaminants may migrate from, within or through these properties. These releases or migrations may give rise to claims. Where third parties are responsible for contamination, the third parties may not have funds, or not make funds available when needed, to pay remediation costs imposed upon the Company under environmental laws and regulations. The Company is responsible for the maintenance of discontinued coal mining operations in Germany. The risk of environmental remediation exists, and the Company is in the process of remediating the mines considered to be the most at risk. 3) Financial Risks: Reorganization activities may lead to additional costs and material adverse effects. In the past, the Company has taken actions to restructure and optimize its production and manufacturing capabilities and efficiencies through relocations, consolidations, plant closings or asset sales. In the future, the Company may take additional restructuring actions including the consolidating, closing or selling of additional facilities. These actions could result in 14 impairment charges and various charges for such items as idle capacity, disposition costs and severance costs, in addition to normal or attendant risks and uncertainties. The Company may be unsuccessful in any of its current or future efforts to restructure or consolidate its business. Plans to minimize or eliminate any loss of revenues during restructuring or consolidation may not be achieved. These activities may have a material adverse effect upon the Company’s business, financial condition and results of operations. The Company’s ability to manage currency or commodity price fluctuations or supply shortages is limited. As a resource-intensive manufacturing operation, the Company is exposed to a variety of market and asset risks, including the effects of changes in commodity prices, foreign currency exchange rates, and interest rates. The Company has multiple sources of supply for the majority of its commodity requirements. However, significant shortages that disrupt the supply of raw materials or result in price increases could affect prices the Company charges its customers, its product costs, and the competitive position of its products and services. The Company monitors and manages these exposures as an integral part of its overall risk management program, which recognizes the unpredictability of markets and seeks to reduce the potentially adverse effects on its results. Nevertheless, changes in currency exchange rates, commodity prices and interest rates cannot always be predicted. In addition, because of intense price competition and the Company’s high level of fixed costs, it may not be able to address such changes even if they are foreseeable. Substantial changes in these rates and prices could have a material adverse effect on the Company’s results of operations and financial condition. In addition, significant portions of its revenues and earnings are exposed to changes in foreign currency rates. As it operates in multiple foreign currencies, changes in those currencies relative to the U.S. dollar will impact its revenues and expenses. The impact of possible currency devaluation in countries experiencing high inflation rates or significant exchange fluctuations can impact the Company’s results and financial guidance. For additional discussion of interest rate, currency or commodity price risk, see Item 7A, Quantitative and Qualitative Disclosures about Market Risk. The Company’s effective tax rate could materially increase as a consequence of various factors, including U.S. and/or international tax legislation, mix of the Company’s earnings by jurisdiction, and U.S. and non-U.S. jurisdictional tax audits. The Company is subject to taxes in the U.S. and numerous non-U.S. jurisdictions. Therefore, it is subject to changes in tax laws in each of these jurisdictions, including changes discussed in the paragraphs below. The outcome of these and other legislative developments, including changes to interpretations of recently enacted legislation, could have a material adverse effect on the Company’s future effective tax rate and cash flows. U.S. tax legislative proposals currently being considered in a bill referred to as “Build Back Better” could, among other things, increase the Company’s U.S. taxes on non-U.S. earnings, effective in 2023. In addition, the Organization for Economic Cooperation and Development (“OECD”) is working with a group of more than 100 countries to significantly change the tax treatment of multinational businesses, subjecting them to tax in additional jurisdictions, modifying the methods by which they allocate profits among jurisdictions, and subjecting them to a minimum level of tax. As part of this effort, during 2021, the OECD reached a near-unanimous agreement among the working group jurisdictions to apply a minimum income tax rate of 15%, on a country-by-country basis. In December of 2021, the OECD published model rules to assist with implementation of the minimum tax regime, proposed to be effective in 2023, and the European Union published a directive that would incorporate the OECD-led minimum tax proposals into European Union law. The Company’s income tax rate in certain non- U.S. jurisdictions is lower than 15%. Enactment of these minimum tax proposals, and the other proposals discussed above, could have a material adverse effect on the Company’s future effective tax rate and cash flows. Certain European jurisdictions, including Germany and the Netherlands, have enacted or will enact tax legislation based upon directives from the European Union. Such legislation could potentially deny tax deductions for certain expenses and/or subject to tax the income earned in certain low tax jurisdictions. The Company has two subsidiaries in China which benefit from lower income tax rates due to “tax holidays” which apply for three-year periods. The tax holiday for one of the subsidiaries expires at the end of 2022, and for the other subsidiary the tax holiday will expire at the end of 2023. Future year tax benefits will depend upon the Company’s ability to obtain extensions, after the three-year periods expire. There can be no assurance that future extensions will be granted. The tax rates applicable in the jurisdictions within which the Company operates vary widely. Therefore, the Company’s effective tax rate may be adversely affected by changes in the mix of its earnings by jurisdiction. The Company’s tax returns are subject to examination by various U.S. and non-U.S. tax authorities, including the U.S. Internal Revenue Service. The Company regularly assesses the likelihood of an adverse outcome resulting from these examinations to determine the adequacy of its provision for income taxes. However, there can be no assurance as to the outcome of these examinations. 15 A decline in expected profitability of the Company or individual reporting units of the Company could result in the impairment of assets, including goodwill and other long-lived assets. The Company continues to hold material amounts of goodwill and other long-lived assets on its balance sheet. A decline in expected profitability, particularly if there is a decline in the global economy, could call into question the recoverability of the Company’s related goodwill and other long-lived tangible and intangible assets and require the write-down or write-off of these assets. Such an occurrence could have a material adverse effect on the Company’s consolidated results of operations, financial position and cash flows. A significant fluctuation between the U.S. dollar and other currencies could adversely impact the Company's revenue and earnings. Although the Company's financial results are reported in U.S. dollars, the majority of the Company’s operations consist of manufacturing and sales activities in foreign countries. The Company’s most significant net long exposure is to the euro. The Company’s most significant net short exposures are to the Chinese renminbi, Mexican peso, and Philippine peso. Changes in foreign exchange rates could have an adverse effect on the Company's results of operations, financial position and cash flows. The Company’s revenues may vary significantly from period to period. The Company’s revenues may vary significantly from one period to another due to a variety of factors including: • • • • • • • • • • • • changes in customers’ buying decisions; changes in demand for its products; changes in its distributor inventory stocking; the Company’s product mix; the Company’s effectiveness in managing manufacturing processes; costs and timing of its component purchases; the effectiveness of its inventory control; the degree to which it is able to utilize its available manufacturing capacity; the Company’s ability to meet delivery schedules; general economic and industry conditions; local conditions and events that may affect its production volumes, such as labor conditions and political instability; and seasonality of certain product lines. The bankruptcy or insolvency of a major customer could adversely affect the Company. The bankruptcy or insolvency of a major customer could result in lower sales revenue and cause a material adverse effect on the Company’s consolidated results of operations, financial position and cash flows. In addition, the bankruptcy or insolvency of a major auto manufacturer or significant supplier likely could lead to substantial disruptions in the automotive supply base, resulting in lower demand for the Company’s products, which would likely cause a decrease in sales revenue and have a substantial adverse impact on the Company’s consolidated results of operations, financial position and cash flows. The inability to maintain access to capital markets may adversely affect the Company’s business and financial results. The Company’s ability to invest in its businesses, make strategic acquisitions, and refinance maturing debt obligations may require access to the capital markets and sufficient bank credit lines to support short-term borrowings. If the Company is unable to access the capital markets or bank credit facilities, it could experience a material adverse effect on its consolidated results of operations, financial position and cash flows. Fixed costs may reduce operating results if sales fall below expectations. The Company’s expense levels are based, in part, on its expectations for future sales. Many of the Company’s expenses, particularly those relating to capital equipment and manufacturing overhead, are relatively fixed. The Company might not be able to reduce spending quickly enough to compensate for reductions in sales. Accordingly, shortfalls in sales could materially and adversely affect the Company’s consolidated results of operations, financial position and cash flows. The volatility of the Company’s stock price could affect the value of an investment in the Company’s stock and future financial position. 16 The market price of the Company’s stock can fluctuate widely. Between December 26, 2020 and January 1, 2022, the closing sale price of the Company’s common stock ranged between a low of $234.59 and a high of $334.84. The volatility of the stock price may be related to any number of factors, such as volatility in the financial markets, general macroeconomic conditions, industry conditions, market expectations concerning the Company’s results of operations, or the volatility of its revenues as discussed above under “The Company’s Revenues May Vary Significantly from Period to Period.” The historic market price of the Company’s common stock may not be indicative of future market prices. The Company may not be able to sustain or increase the value of its common stock. Declines in the market price of the Company’s stock could adversely affect the Company’s ability to retain personnel with stock incentives, to acquire businesses or assets in exchange for stock and/or to conduct future financing activities with or involving the Company’s common stock. The Company is exposed to, and may be adversely affected by, potential security breaches or other disruptions to its information technology systems and data security. The Company relies on its information technology systems and networks in connection with many of its business activities. Some of these networks and systems are managed directly by the Company, while others are managed by third-party service providers and are not under the Company’s direct control. The Company’s operations routinely involve receiving, storing, processing and transmitting sensitive information pertaining to its business, customers, dealers, suppliers, employees, and other sensitive matters. As with most companies, the Company has experienced cyber-attacks, attempts to breach its systems, and other similar incidents, none of which have been material. Any future cyber incidents could, however, materially disrupt operational systems; result in loss of trade secrets or other proprietary or competitively sensitive information; compromise personally identifiable information regarding employees or customers or other third parties; and jeopardize the security of the Company’s facilities. A cyber incident could be caused by malicious outsiders using sophisticated methods to circumvent firewalls, encryption, and other security defenses. Because techniques used to obtain unauthorized access or to sabotage systems change frequently and generally are not recognized until they are launched against a target, the Company may be unable to anticipate these techniques or to implement adequate preventative measures. Information technology security threats, including security breaches, computer malware, and other cyber-attacks are increasing in both frequency and sophistication and could create financial liability, subject the Company to legal or regulatory sanctions or damage the Company’s reputation with customers, dealers, suppliers, and other stakeholders. The Company continuously seeks to maintain a robust program of information security and controls, but the impact of a material information technology event could have a material adverse effect on the Company’s competitive position, reputation, results of operations, financial position and cash flows. Customer demands and regulations related to conflict-free minerals may force the Company to incur additional expenses. The Dodd-Frank Wall Street Reform and Consumer Protection Act requires disclosure of use of “conflict” minerals mined from the Democratic Republic of Congo and adjoining countries and efforts to prevent the use of such minerals. In the semiconductor industry, these minerals are most commonly found in metals. As there may be only a limited number of suppliers offering “conflict free” metals, the Company cannot be certain that it will be able to obtain necessary metals in sufficient quantities or at competitive prices. Also, the Company may face challenges with its customers and suppliers if it is unable to sufficiently verify that the metals used in its products are “conflict free.” ITEM 1B. UNRESOLVED STAFF COMMENTS. None. ITEM 2. PROPERTIES.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS. The following discussion of the Company's financial condition and results of operations should be read together with the Consolidated Financial Statements and notes to those statements included in Item 8 of Part II of this Annual Report on Form 10-K. BUSINESS For a description of the Company’s business, segments and product offerings, see Item 1, Business. 2021 EXECUTIVE OVERVIEW Net sales increased by $634.2 million or 43.9% including $27.4 million or 1.9% of favorable changes in foreign exchange rates in 2021 compared to 2020. The increase was due to volume growth across all segments and businesses while 2020 had temporary closures of manufacturing facilities resulting from government directives due to the impact of COVID-19. The increase was due to higher sales of $363.0 million, $138.9 million, and $132.3 million in the Electronics, Industrial, and Transportation segments, respectively, driven by higher volumes across all businesses within these segments. The volume increase within the Electronics segment was led by broad-based demand across electronics, transportation and industrial end markets. The increase with the Industrial segment was primarily due to $100.5 million of net sales resulting from the Hartland acquisition and volume growth across all businesses within the Industrial segment. The increase within the Transportation segment was due to volume growth driven by higher demand in the global auto and commercial vehicle markets, greater content growth across passenger vehicles due to vehicle mix, including growth in electric vehicles and some customers maintaining additional inventory of our products, and $15.3 million of net sales resulting from the Carling acquisition. The Company recognized net income of $283.8 million, or $11.38 per diluted share, in 2021 compared to net income of $130.0 million, or $5.29 per diluted share in 2020. The increase in net income reflects higher operating income of $223.3 million driven by a $156.9 million increase in operating income in the Electronics segment, the 2020 goodwill impairment charge of $33.8 million, a $24.3 million increase in operating income in the Transportation segment partially offset by higher foreign exchange losses of $32.0 million and a $19.9 million non-cash pension settlement charge associated with the completion of the buy-out of one of our U.K. pension plans. Supply chain constraints, including transportation capacity shortages have and are expected to continue to impact the Company, our suppliers and our customers. This has resulted in higher transportation and input costs incurred by the Company. 21 Net cash provided by operating activities was $373.3 million for the fiscal year ended January 1, 2022 representing an increase of $115.3 million as compared to the fiscal year ended December 26, 2020. The increase in net cash provided by operating activities was primarily due to higher cash earnings partially offset by increases in working capital resulting from higher sales growth. On January 28, 2021, the Company acquired Hartland Controls, a manufacturer and leading supplier of electrical components used primarily in HVAC and other industrial and control systems applications. At the time of acquisition, Hartland had annualized sales of approximately $70 million. The purchase price for Hartland was $111.0 million and the operations of Hartland are included in the Industrial segment. On November 30, 2021, the Company acquired Carling, a leader in switching, circuit protection and power distribution technologies with a strong global presence in commercial transportation, communications infrastructure and marine markets. At the time of acquisition, Carling had annualized sales of approximately $170 million. The purchase price for Carling was approximately $315 million and the operations of Carling are included in the Transportation segment. Impact of COVID-19 on Business The effects from COVID-19 continue to drive increased costs, though less than net costs incurred in 2020. Ongoing costs include spending on personal protective equipment ("PPE"), additional personnel and employee transportation costs, and manufacturing inefficiencies. as well as an increase in material costs and transportation costs due to global supply chain and logistics constraints around the world. During 2021, all of our manufacturing facilities were operational and were generally running at normal capacity levels. The Company anticipates that the disruptions caused by COVID-19 may continue to impact its business activity for the foreseeable future. It is currently difficult to estimate the magnitude of the COVID-19 disruption, if future disruptions will occur due to a resurgence in COVID-19 cases and its impact on our employees, customers, suppliers and vendors. The Company will continue to actively monitor the situation and may take further actions altering our business operations that we determine are in the best interests of our employees, customers, partners, suppliers, and other stakeholders, or as required by federal, state, or local authorities. It is not clear what the potential effects any such alterations or modifications may have on our business and operations, including the effects on our customers, employees, and prospects, or on our financial results for the fiscal year 2022. OUTLOOK Vision and Strategy The Company closely collaborates with strategic customers to design and manufacture innovative and reliable solutions to help empower a sustainable, connected, and safer world in virtually every market that uses electrical energy. Within transportation end markets, the Company’s products are found in passenger vehicles and commercial vehicles, like material handling equipment, heavy-duty truck and bus, off-road and recreational vehicles, construction equipment, agricultural machinery, rail and marine. The Company is also a key enabler of electrification, or eMobility, across these transportation applications, and EV charging infrastructure. The Company continues to advance its existing customer relationships with OEM, Tier one and channel partners while driving product content growth for advanced, high-growth applications. Within industrial end markets, the Company’s products are found in renewable energy and energy storage applications, HVAC, factory automation and safety, industrial motor drives and power conversion, and heavy and general industrial type applications. The Company utilizes its deep technical engineering capabilities and design support to drive product content growth across high-growth applications like renewables, energy storage, HVAC, and industrial automation. Within electronics end markets, the Company’s products are found in data center, cloud storage and telecom infrastructure applications, building technologies and automation, appliances, mobile electronics, medical devices, and gaming and entertainment applications. The Company leverages its strategic distribution partnerships and deep OEM relationships, coupled with its comprehensive product offerings, to drive product content growth across a broad range of applications. The Company expects the ever-increasing complexity of application architectures, driven by ongoing electronification and electrification across these end markets, to drive increasing product content opportunities. Built upon that framework, the Company has positioned itself around the structural growth themes of sustainability, connectivity, and safety, which will 22 continue to drive increased demand for the Company’s innovative, reliable solutions across the transportation, industrial and electronics end markets that it serves. The Company’s five-year strategic plan, built around these structural growth themes, is focused on delivering top tier shareholder returns by driving double-digit sales growth, best-in-class profitability, earnings per share growth, strong cash flow generation, and deploying capital to drive value creation. The Company pursues the following major strategic objectives, which are summarized below, along with more specific areas of focus. The Company uses the financial measures below to gauge progress toward achieving these strategic objectives. These measures include organic sales growth, operating margins, cash flow from operations, and returns on invested capital. Strategic Objectives Priorities Double-digit sales growth 5-7% average annual growth from annual organic sales growth 5-7% average annual growth from strategic acquisitions EPS growth Earnings per share growth greater than revenue growth Capital allocation and returns Cash flow from operations less capital expenditures is targeted to approximate or exceed net income Target 40% of free cash flow returned to shareholders Remainder focused on strategic acquisitions Return on invested capital percentage in the high-teens ● ● ● ● ● ● ● ● ● ● ● ● ● Increased product content with existing and new customers, and expand market share Expand portfolio into new and underpenetrated, high-growth geographies and end markets Increase innovation capabilities and investments Leverage breadth of go-to-market strategies Targeted mergers and acquisitions to enhance and sustain organic growth Focus on higher profitability growth opportunities Improve operating margins through operational and commercial excellence Disciplined approach to balancing costs with long-term strategic investments Disciplined management of working capital Deployment of capital consistent with capital allocation priorities Mergers and acquisitions that align with strategy and financial metrics Grow dividend in line with earnings Opportunistic share repurchases The Company’s strategy is focused on accelerating organic growth by increasing its product content in applications and share gains, enhancing technology efforts to drive innovation, capitalizing on cross segment opportunities, and gaining traction in underpenetrated, high-growth geographies and end markets. The Company also leverages strategic acquisitions to enhance and sustain its organic growth. The Company will continue to make targeted strategic acquisitions that align to its strategy and financial metrics to drive growth across its business, products, markets, and technologies while leveraging existing customers and targeting new customers. Management believes that profitable growth through a combination of organic growth and strategic acquisitions is critical to the Company’s competitiveness, while enhancing value the Company delivers to all of its stakeholders. In addition, the Company continues to implement initiatives across all platforms to enhance productivity while managing its cost structure to align with business conditions. Areas of focus include integration of operations and streamlining administrative and support activities to drive improved operating margins. The Company seeks to deploy its capital consistent with capital allocation priorities. These priorities include investments to drive increased organic growth, targeted acquisitions that align to the Company’s strategic and financial metrics, and enhance and sustain its organic growth, and returning capital to shareholders through dividends and opportunistic share repurchases. Critical Estimates and Significant Accounting Policies 23 The preparation of financial statements in conformity with 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. The Company’s most critical accounting policies are those that are most important to the portrayal of its financial condition and results of operations, and which require the Company to make its most difficult and subjective judgments, often as a result of the need to make estimates of matters that are inherently uncertain. The Company has identified the following as its most critical accounting policies and judgments. Although management believes that its estimates and assumptions are reasonable, they are based upon information available when they are made, and therefore, actual results may differ from these estimates under different assumptions or conditions. The Company has reviewed these critical accounting policies and related disclosures with the Audit Committee of its Board of Directors. Significant accounting policies are more fully described in the Notes to Consolidated Financial Statements included elsewhere in this Annual Report. Critical Accounting Estimates Goodwill The Company’s methodology for allocating the purchase price of acquisitions is based on established valuation techniques that reflect the consideration of a number of factors, including valuations performed by third-party appraisers when appropriate. Goodwill is measured as the excess of the cost of an acquired entity over the fair value assigned to identifiable assets acquired and liabilities assumed. Based on its current organization structure, the Company has seven reporting units for which cash flows are determinable and to which goodwill has been allocated. The Company annually tests goodwill for impairment on the first day of its fiscal fourth quarter, or more frequently if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying value. The Company also performs an interim review for indicators of impairment each quarter to assess whether an interim impairment review is required for any reporting unit. As part of its interim reviews, management analyzes potential changes in the value of individual reporting units based on each reporting unit’s operating results for the period compared to expected results as of the prior year’s annual impairment test. In addition, management considers how other key assumptions, including discount rates and expected long-term growth rates, used in the last annual impairment test, could be impacted by changes in market conditions and economic events. During the second quarter of 2020, the Company recorded a non-cash charge of $33.8 million to recognize the impairment of goodwill in the automotive sensors reporting unit within the Transportation segment. As of January 1, 2022, the automotive sensors reporting unit had $9.2 million of remaining goodwill. Quantitative Assessment for Impairment For the seven reporting units with goodwill, the Company compares the estimated fair value of each reporting unit to its carrying value. If the carrying value of a reporting unit exceeds the estimated fair value, the difference between the estimated fair value and carrying value is recorded as the amount of the goodwill impairment charge. The results of the goodwill impairment test as of September 26, 2021 indicated that the estimated fair values for each of the seven reporting units exceeded their respective carrying values. Accordingly, there were no goodwill impairment charges recorded as part of the Company’s 2021 annual goodwill impairment test. As part of its impairment test for these reporting units, the Company engaged a third-party appraisal firm to assist in the Company’s determination of the estimated fair values. This determination included estimating the fair value of each reporting unit using both the income and market approaches. The income approach requires management to estimate a number of factors for each reporting unit, including projected operating results, economic projections, anticipated future cash flows, discount rates and the allocation of shared or corporate items. The market approach estimates fair values using comparable marketplace fair value data from within a comparable industry grouping. The Company weighted both the income and market approach equally to estimate the concluded fair value of each reporting unit. The determination of fair value requires the Company to make significant estimates and assumptions, which primarily include, but are not limited to: the selection of appropriate peer group companies; control premiums appropriate for acquisitions in which the Company competes; the discount rate; terminal growth rates; and forecasts of revenue, operating income, depreciation and amortization and capital expenditures. Goodwill Impairment Assumptions 24 Although the Company believes its estimates of fair value are reasonable, actual financial results could differ from those estimates due to the inherent uncertainty involved in making such estimates. Changes in assumptions concerning future financial results or other underlying assumptions could have a significant impact on the fair value of the reporting units. Future declines in the overall market value of the Company’s equity may also result in a conclusion that the fair value of one or more reporting units has declined below its carrying value. One measure of the sensitivity of the amount of goodwill impairment charges to key assumptions is the amount by which each reporting unit “passed” (fair value exceeds the carrying value) the goodwill impairment test. All seven of the reporting units passed the goodwill impairment test, with fair values that exceeded the carrying values between 95% and 380% of their respective estimated fair values. As of the most recent annual test conducted on September 26, 2021, the Company noted that the excess of fair value over the carrying value was 380%, 104%, 255%, 217%, 95%, 144%, and 231% for its reporting units: Electronics-Passive Products and Sensors, Electronics-Semiconductor, Passenger Car Products, Commercial Vehicle Products, Automotive Sensors, Relays, and Power Fuse, respectively. Relatively small changes in the Company’s key assumptions would not have resulted in any reporting units failing the goodwill impairment test. Generally, changes in estimates of expected future cash flows would have a similar effect on the estimated fair value of the reporting unit. That is, a 1.0% decrease in estimated annual future cash flows would decrease the estimated fair value of the reporting unit by approximately 1.0%. The estimated long-term net sales growth rate can have a significant impact on the estimated future cash flows, and therefore, the fair value of each reporting unit. A 1.0% decrease in the long-term net sales growth rate would have resulted in no reporting units failing the goodwill impairment test. Of the other key assumptions that impact the estimated fair values, most reporting units have the greatest sensitivity to changes in the estimated discount rate. The estimated discount rate was 8.9% for the Electronics-Passive Products and Sensors and the Passenger Car Products reporting units, 9.9% for the Electronics-Semiconductor, Commercial Vehicle Products and the Automotive Sensors reporting units, 10.9% for the Power Fuse reporting unit and 11.9% for the Relays reporting unit. A 1.0% increase in the estimated discount rates would have resulted in no reporting units failing the annual goodwill impairment test. The Company believes that its estimates of future cash flows and discount rates are reasonable, but future changes in the underlying assumptions could differ due to the inherent uncertainty in making such estimates. Additionally, price deterioration or lower volume could have a significant impact on the fair values of the reporting units. Income Taxes The Company accounts for income taxes using the asset and liability method. Deferred taxes are recognized for the future effects of temporary differences between financial and income tax reporting using tax rates in effect for the years in which the differences are expected to reverse. The Company recognizes deferred taxes for temporary differences, operating loss carryforwards and tax credit and other tax attribute carryforwards (excluding carryforwards where usage has been determined to be remote). Deferred tax assets are reduced by a valuation allowance if it is more likely than not that some portion, or all, of the deferred tax assets will not be realized. U.S. state and non-U.S. income taxes are provided on the portion of non-U.S. income that is expected to be remitted to the U.S. and be taxable (and non-U.S. income taxes are provided on the portion of non-U.S. income that is expected to be remitted to an upper-tier non-U.S. entity). Deferred tax assets and liabilities are adjusted for the effects of changes in tax laws and rates on the date of enactment. Deferred income taxes are not provided on the excess of the investment value for financial reporting over the tax basis of investments in those non-U.S. subsidiaries for which such excess is considered to be permanently reinvested in those operations. Management regularly evaluates whether non-U.S. earnings are expected to be permanently reinvested. This evaluation requires judgment about the future operating and liquidity needs of the Company and its non-U.S. subsidiaries. Changes in economic and business conditions, non-U.S. or U.S. tax laws, or the Company’s financial situation could result in changes to these judgments and the need to record additional tax liabilities. The Company recognizes the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the financial statements from such a position are measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement. The 2017 Tax Cuts and Jobs Act (the "Tax Act"), among other things, imposed a one-time tax (the “Toll Charge”) on accumulated earnings of certain non-U.S. subsidiaries and included base broadening provisions commonly referred to as the global intangible low-taxed income provisions ("GILTI"). In accordance with guidance issued by the FASB staff, the Company has adopted an accounting policy to treat any GILTI inclusions as a period cost if and when incurred. Thus, for the fiscal years ended January 1, 2022, December 26, 2020, and 25 December 28, 2019, deferred taxes were computed without consideration of the possible future impact of the GILTI provisions, and any current year impact was recorded as a part of the current portion of income tax expense. Further information regarding income taxes, including a detailed reconciliation of current year activity, is provided in Note 14, Income Taxes, of the Notes to Consolidated Financial Statements included in this Annual Report. Critical Accounting Policies Revenue Recognition Revenue Disaggregation The following table disaggregates the Company’s revenue by primary business units for the fiscal years ended January 1, 2022 and December 26, 2020: (in thousands) Electronics Segment Fiscal Year Ended January 1, 2022 Industrial Segment Transportation Segment Total Electronics – Semiconductor $ 678,861 $ Electronics – Passive Products and Sensors 621,883 — $ — 266,020 160,300 101,738 — $ 678,861 — — — — 621,883 266,020 160,300 101,738 251,126 — 251,126 $ 1,300,744 $ 528,058 $ 251,126 $ 2,079,928 Fiscal Year Ended December 26, 2020 — $ — 200,455 101,324 93,985 — Total — $ 522,352 — — — — 112,169 415,410 200,455 101,324 93,985 112,169 — — — — — — — — (in thousands) Electronics Segment Transportation Segment Industrial Segment Electronics – Semiconductor $ 522,352 $ Electronics – Passive Products and Sensors 415,410 Passenger Car Products Commercial Vehicle Products Automotive Sensors Industrial Products Total Passenger Car Products Commercial Vehicle Products Automotive Sensors Industrial Products Total $ 937,762 $ 395,764 $ 112,169 $ 1,445,695 See Note 16, Segment Information, for net sales by segment and countries. Revenue Recognition The Company recognizes revenue on product sales in the period in which the Company satisfies its performance obligation and control of the product is transferred to the customer. The Company’s sales arrangements with customers are predominately short term in nature and generally provide for transfer of control at the time of shipment as this is the point at which title and risk of loss of the product transfers to the customer. At the end of each period, for those shipments where title to the products and the risk of loss and rewards of ownership do not transfer until the product has been received by the customer, the Company adjusts revenues and cost of sales for the delay between the time that the products are shipped and when they are received by the customer. The amount of revenue recorded reflects the consideration to which the Company expects to be entitled in exchange for goods and may include adjustments for customer allowance, rebates and price adjustments. The Company’s sales channels are primarily through direct sales and independent third-party distributors. The Company has elected the practical expedient under Accounting Standards Codification ("ASC") 340-40-25-4 to expense commissions when incurred as the amortization period of the commission asset the Company would have otherwise recognized is less than one year. 26 Revenue and Billing The Company generally accepts orders from customers through receipt of purchase orders or electronic data interchange based on written sales agreements and purchasing contracts. Contract pricing and selling agreement terms are based on market factors, costs, and competition. Pricing is often negotiated as an adjustment (premium or discount) from the Company’s published price lists. The customer is invoiced when the Company’s products are shipped to them in accordance with the terms of the sales agreement. As the Company’s standard payment terms are less than one year, the Company has elected the practical expedient under ASC 606-10-32-18 to not assess whether a contract has a significant financing component. The Company also elected the practical expedient provided in ASC 606-10-25-18B to treat all product shipping and handling activities as fulfillment activities, and therefore recognize the gross revenue associated with the contract, inclusive of any shipping and handling revenue. Ship and Debit Program Some of the terms of the Company’s sales agreements and normal business conditions provide customers (distributors) the ability to receive price adjustments on products previously shipped and invoiced. This practice is common in the industry and is referred to as a “ship and debit” program. This program allows the distributor to debit the Company for the difference between the distributors’ contracted price and a lower price for specific transactions. Under certain circumstances (usually in a competitive situation or large volume opportunity), a distributor will request authorization for pricing allowances to reduce its price. When the Company approves such a reduction, the distributor is authorized to “debit” its account for the difference between the contracted price and the lower approved price. The Company establishes reserves for this program based on historic activity, electronic distributor inventory levels and actual authorizations for the debit and recognizes these debits as a reduction of revenue. Return to Stock The Company has a return to stock policy whereby certain customers, with prior authorization from the Company's management, can return previously purchased goods for full or partial credit. The Company establishes an estimated allowance for these returns based on historic activity. Sales revenue and cost of sales are reduced to anticipate estimated returns. Volume Rebates The Company offers volume-based sales incentives to certain customers to encourage greater product sales. If customers achieve their specific quarterly or annual sales targets, they are entitled to rebates. The Company estimates the projected amount of rebates that will be achieved by the customer and recognizes this estimated cost as a reduction to revenue as products are sold. Allowance for Doubtful Accounts The Company currently measures the expected credit losses based on our historical credit loss experience. The Company has not experienced significant recent or historical credit losses and is not forecasting any significant credit losses which would require adjustments to our methodology. If current conditions and supportable forecasts indicate that our historical loss experience is not reasonable and no longer supportable, the Company may adjust its historical credit loss experience and to reflect these conditions and forecasts. The Company regularly analyzes its significant customer accounts and, when the Company becomes aware of a customer’s inability to meet its financial obligations, the Company records a specific reserve for bad debt to reduce the related receivable to the amount the Company reasonably believes is collectible. The Company also analyzes all other customers based on a variety of factors including the length of time the receivables are past due, the financial health of the customer, macroeconomic considerations and historical collection and loss experience. Historically, the allowance for doubtful accounts has been adequate to cover bad debts. If circumstances related to specific customers change, the estimates of the recoverability of receivables could be further adjusted. Inventory The Company performs regular detailed assessments of inventory, which include a review of, among other factors, demand requirements, product life cycle and development plans, component cost trends, product pricing, shelf life, and quality issues. Based on the analysis, the Company records adjustments to inventory for excess quantities, obsolescence or impairment when appropriate to reflect inventory at net realizable value. Historically, inventory reserves have been adequate to reflect inventory at net realizable value. 27 Long-Lived Assets The Company evaluates the recoverability of other long-lived assets, including property, plant and equipment and certain identifiable intangible assets, whenever events or changes in circumstances indicate that the carrying value of an asset or asset group may not be recoverable. Factors which could trigger an impairment review include significant underperformance relative to historical or projected operating results, significant changes in the manner of use of the assets or the strategy for the overall business, a significant decrease in the market value of the assets or significant negative industry or economic trends. When the Company determines that the carrying value of long-lived assets may not be recoverable based upon the existence of one or more of the indicators, the assets are assessed for impairment based on the estimated future undiscounted cash flows expected to result from the use of the asset and its eventual disposition. If the carrying value of an asset exceeds its estimated future undiscounted cash flows, an impairment loss is recorded for the excess of the asset’s carrying value over its fair value. For the fiscal year ended December 26, 2020, the Company recognized a $2.2 million impairment charge related to the land and building associated with the Company’s announced consolidation of a manufacturing facility within the Industrial segment. For the year-ended December 28, 2019, the Company recognized non-cash impairment charges of $0.3 million for certain machinery and equipment related to the closure of a European manufacturing facility in the automotive sensors business within the Transportation segment. Environmental Liabilities Environmental liabilities are accrued based on estimates of the probability of potential future environmental exposure. Costs related to on-going maintenance of environmental sites are expensed as incurred. If actual or estimated probable future losses exceed the Company’s recorded liability for such claims, it would record additional charges as other expense during the period in which the actual loss or change in estimate occurred. The Company evaluates its reserve for coal mine remediation annually utilizing a third-party expert. Pension Plans The Company records annual income and expense amounts relating to its pension and postretirement benefits plans based on calculations which include various actuarial assumptions including discount rates, expected long-term rates of return and compensation increases. The Company reviews its actuarial assumptions on an annual basis as of the fiscal year-end balance sheet date (or more frequently if a significant event requiring remeasurement occurs) and modifies the assumption based on current rates and trends when it is appropriate to do so. The effects of modifications are recognized immediately on the Consolidated Balance Sheets but are generally amortized into operating earnings over future periods, with the deferred amount recorded in accumulated other comprehensive (loss) income. The Company believes that the assumptions utilized in recording its obligations under its plans are reasonable based on its experience, market conditions and input from its actuaries and investment advisors. The Company maintains several pension plans in international locations. The expected returns on plan assets and discount rates are determined based on each plan’s investment approach, local interest rates and plan participant profiles. The weighted-average discount rates for the Company’s defined benefit plans primarily in Europe and the Asia-Pacific regions at January 1, 2022 and December 26, 2020 were 3.1% and 1.2%, respectively. A 50 basis point change in the discount rates at January 1, 2022 would have the following effect on the projected benefit obligation: (in millions) Projected benefit obligation 0.5% Increase 0.5% Decrease $ (5.9) $ 6.4 On April 7, 2020, the Company entered into a definitive agreement to purchase a group annuity contract, under which an insurance company will be required to directly pay and administer pension payments to certain of the Company’s U.K. pension plan participants, or their designated beneficiaries. The Company completed the buy-out of this U.K. pension plan during the fourth quarter of 2021 and as a result recorded a non-cash pension settlement charge of $19.9 million (£14.9 million), inclusive of the accelerated recognition of prior service cost of $0.5 million (£0.4 million). The purchase of this group annuity contract reduced the Company’s outstanding pension benefit obligation by $47.1 million, representing 35% of the total obligation of the Company’s qualified pension plans. Equity-based Compensation Equity-based compensation expense is recorded for stock-option awards and restricted share units based upon the fair values of the awards. The fair value of stock-option awards is estimated at the grant date using the Black-Scholes option pricing model, 28 which includes assumptions for volatility, expected term, risk-free interest rate and dividend yield. Expected volatility is based on implied volatilities from traded options on Littelfuse stock, historical volatility of Littelfuse stock and other factors. Historical data is used to estimate employee termination experience and the expected term of the options. The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant. The Company initiated a quarterly cash dividend in 2010 and expects to continue making cash dividend payments for the foreseeable future. The fair value of restricted share units is determined based on the Company's stock price on the grant date reduced by the present value of expected dividends through the vesting period. Total equity-based compensation expense for all equity compensation plans was $21.4 million, $19.1 million, and $19.9 million in 2021, 2020, and 2019, respectively. Further information regarding this expense is provided in Note 12, Stock-Based Compensation, of the Notes to Consolidated Financial Statements included in this Annual Report. Off-Balance Sheet Arrangements The Company does not have off-balance sheet arrangements as defined under SEC rules. The Company does not participate in transactions that generate relationships with unconsolidated entities or financial partnerships, such as entities often referred to as structured finance or special purpose entities. In the financial review that follows, the Company discusses its consolidated results of operations, financial position, cash flows and certain other information. This discussion should be read in conjunction with the Company’s Consolidated Financial Statements and related notes. RESULTS OF OPERATIONS FOR THE YEAR ENDED JANUARY 01, 2022 AS COMPARED TO THE YEAR ENDED DECEMBER 26, 2020 The fiscal year 2021 included approximately $12.6 million of non-segment charges, of which $8.4 million relates to purchase accounting inventory step-up charges, $7.0 million of acquisition-related and integration charges related to the Carling and Hartland acquisitions and other contemplated acquisitions, and $2.2 million of restructuring, impairment and other charges, primarily related to employee termination costs. See Note 8, Restructuring, Impairment and Other Charges, for further discussion. Additionally, partially offsetting the above amounts was a gain of $5.0 million recorded for the sale of buildings within the Electronics segment. The fiscal year 2020 included approximately $44.0 million of non-segment charges, of which $2.3 million of charges are acquisition-related and integration charges related to the IXYS acquisition and other contemplated acquisitions. In addition, there were $41.7 million of restructuring, impairment and other charges, primarily related to the goodwill impairment charge of $33.8 million recorded in the second quarter associated with the automotive sensors reporting unit within the Transportation segment, employee termination costs of $5.5 million, $2.2 million of impairment charges recorded in the first quarter associated with the announced consolidation of a manufacturing facility within the Industrial segment and other restructuring charges of $0.2 million. Fiscal year 2021 also included approximately $17.2 million in foreign currency exchange losses primarily attributable to changes in the value of the Euro, Chinese renminbi, Mexican peso, and Philippine peso against the U.S. dollar, while fiscal year 2020 included approximately $14.9 million in foreign currency exchange gains primarily attributable to changes in the value of the Euro, Philippine peso, and Chinese renminbi against the U.S. dollar. (in thousands, except % change) Net sales Cost of sales Gross profit Operating expenses Operating income Other expense (income), net Income before income taxes Income taxes Net income $ Fiscal Year 2021 2,079,928 $ 1,308,002 771,926 386,284 385,642 8,932 341,025 57,219 283,806 2020 1,445,695 $ 944,523 501,172 338,800 162,372 (5,083) 161,253 31,267 129,986 Change % Change 634,233 363,479 270,754 47,484 223,270 14,015 179,772 25,952 153,820 43.9 % 38.5 % 54.0 % 14.0 % 137.5 % (275.7) % 111.5 % 83.0 % 118.3 % 29 Net Sales Net sales increased $634.2 million or 43.9% including $27.4 million or 1.9% of favorable changes in foreign exchange rates for 2021 compared to 2020. The increase was due to volume growth across all segments and businesses while 2020 had temporary closures of manufacturing facilities resulting from government directives due to the impact of COVID-19. The increase was due to higher sales of $363.0 million, $138.9 million, and $132.3 million in the Electronics, Industrial, and Transportation segments, respectively, primarily driven by higher volumes across all businesses within these segments. The volume increase within the Electronics segment was led by broad-based demand across electronics, transportation and industrial end markets. The increase within the Industrial segment was primarily due to $100.5 million of net sales resulting from the Hartland acquisition and volume growth across all businesses within the Industrial segment. The increase within the Transportation segment was due to volume growth driven by higher demand in the global auto and commercial vehicle markets, greater content growth across passenger vehicles due to vehicle mix, including growth in electric vehicles and some customers maintaining additional inventory of our products, and $15.3 million of net sales resulting from the Carling acquisition. Cost of Sales Cost of sales was $1,308.0 million, or 62.9% of net sales, in 2021, compared to $944.5 million, or 65.3% of net sales, in 2020. The increase in cost of sales was primarily due to greater volume across all segments driven by the factors discussed above along with the Hartland and Carling acquisitions. As a percent of net sales, cost of sales decreased 2.4% driven by volume leverage, partially offset by higher transportation, duty and tariff charges of 2.2%, the purchase accounting inventory charges of $8.4 million or 0.4% resulting from the Hartland and Carling acquisitions, and higher material costs. Gross Profit Gross profit was $771.9 million, or 37.1% of net sales, in 2021, compared to $501.2 million, or 34.7% of net sales, in 2020. The $270.8 million increase in gross profit was primarily due to higher volume across all segments while 2020 had additional costs associated with government-directed plant shutdowns and supply chain constraints. The increase in gross margin of 2.4% was primarily driven by volume leverage and favorable product mix within the Electronics segment, partially offset by higher transportation, duty and tariff charges as a percent of net sales of 2.2%, the purchase accounting inventory charges of $8.4 million or 0.4%, and higher material costs. Operating Expenses Total operating expenses were $386.3 million, or 18.6% of net sales, for 2021 compared to $338.8 million, or 23.4% of net sales, for 2020. The increase in operating expenses of $47.5 million is primarily due to higher selling, general, and administrative expenses of $71.0 million largely due to higher accrued incentive compensation, the Hartland and Carling acquisitions and higher acquisition-related and integration charges of $4.7 million, and higher research and development expenses of $13.4 million, partially offset by the 2020 goodwill impairment charge of $33.8 million, or 2.3% of net sales, in the automotive sensors reporting unit within the Transportation segment and impairment charges of $2.2 million related to the Company’s 2020 first quarter announcement to consolidate a manufacturing facility within the Industrial segment. Operating Income Operating income for 2021 was $385.6 million, an increase of $223.3 million or 137.5% compared to $162.4 million for 2020. The increase in operating income was primarily due to higher gross margin across all segments, led by the Electronics segment partially offset by higher operating expenses noted above. Operating margins increased from 11.2% in 2020 to 18.5% in 2021 primarily driven by the factors mentioned above. The 2020 goodwill impairment charge of $33.8 million negatively impacted the 2020 operating margin by 2.3%. Income Before Income Taxes Income before income taxes for 2021 was $341.0 million, or 16.4% of net sales compared to $161.3 million, or 11.2% of net sales, for 2020. In addition to the factors impacting comparative results for operating income discussed above, income before income taxes was impacted by foreign exchange losses of $17.2 million during the fiscal year ended January 1, 2022 compared to foreign exchange gains of $14.9 million during the fiscal year ended December 26, 2020, and a $19.9 million non-cash pension settlement charge, partially offset by a $4.0 million increase in unrealized investment gains associated with our equity investment, and lower interest expense of $2.6 million due to lower outstanding borrowings under the credit facility along with a lower effective interest rate and a reduction in coal mining charges of $1.6 million compared to 2020. 30 Income Taxes Income tax expense for 2021 was $57.2 million, or an effective tax rate of 16.8%, compared to income tax expense of $31.3 million, or an effective tax rate of 19.4% for 2020. The Company’s tax rates are lower than the applicable U.S. statutory tax rate primarily due to income earned in lower tax jurisdictions, partially offset by the impact of taxes on unremitted earnings, the GILTI tax provisions, and non-U.S. losses and expenses with no tax benefit. The effective tax rate for 2021 is lower than the effective tax rate for 2020, primarily due to an increase in the income earned in lower tax jurisdictions in 2021 as compared to 2020, as well as the impact of the goodwill impairment charge of $33.8 million recorded in 2020, the substantial majority of which did not result in a tax benefit. Further information regarding these items is provided in Note 14, Income Taxes, of the Notes to Consolidated Financial Statements included in this Annual Report. Segment Information The Company reports its operations by the following segments: Electronics, Transportation and Industrial. Segment information is described more fully in Note 16, Segment Information, of the Notes to Consolidated Financial Statements included in this Annual Report. The following table is a summary of the Company’s net sales by segment: (in millions) Electronics Transportation Industrial Total Electronics Segment Fiscal Year 2021 2020 Change % Change $ $ 1,300.7 $ 528.1 251.1 2,079.9 $ 937.7 $ 395.8 112.2 1,445.7 $ 363.0 132.3 138.9 634.2 38.7 % 33.4 % 123.8 % 43.9 % Net sales for the Electronics segment increased $363.0 million, or 38.7%, in 2021 compared to 2020 and included favorable changes in foreign exchange rates of $14.5 million or 1.5%. The sales increase was primarily due to increased volume for the electronics and semiconductor products businesses of $206.5 million and $156.5 million, respectively. The volume increases were driven by broad-based demand across electronics, transportation and industrial end markets while 2020 were negatively impacted by production disruptions and temporary plant shutdowns due to the impact of COVID-19. Transportation Segment Net sales in the Transportation segment increased $132.3 million, or 33.4%, in 2021 compared to 2020 and included favorable changes in foreign exchange rates of $12.0 million or 3.0%. The sales increase was due to higher volume in passenger car products, commercial vehicle products, and the automotive sensors businesses of $65.6 million, $59.0 million, and $7.8 million, respectively, including the incremental net sales of $15.3 million from the Carling acquisition within the commercial vehicle products business. These increases were due to volume growth driven by higher demand in the global auto and commercial vehicle markets, greater content growth across passenger vehicles due to vehicle mix, including growth in electric vehicles and some customers maintaining additional inventory of our products as compared to 2020, which had production disruptions and temporary plant shutdowns due to the impact of COVID-19. Industrial Segment The Industrial segment net sales increased by $138.9 million, or 123.8%, in 2021 compared to 2020 and included favorable changes in foreign exchange rates of $0.9 million or 0.8%. The increase in net sales was primarily due to the incremental net sales of $100.5 million or 90% from the Hartland acquisition, growth across all product lines, and the transfer of the temperature sensor product line totaling $4.7 million which was previously reported in the Electronics segment and moved to Industrial segment in the third quarter of 2020. Additionally, 2020 was negatively impacted by production disruptions and temporary plant shutdowns due to the impact of COVID-19. Geographic Net Sales Information Net sales by geography represent net sales to customer or distributor locations. The following table is a summary of the Company’s net sales by geography: 31 (in millions) Asia-Pacific Americas Europe Total Asia-Pacific Fiscal Year 2021 2020 Change % Change $ $ 955.7 $ 694.3 429.9 2,079.9 $ 670.5 $ 457.8 317.4 1,445.7 $ 285.2 236.5 112.5 634.2 42.5 % 51.7 % 35.4 % 43.9 % Asia-Pacific net sales increased $285.2 million, or 42.5%, in 2021 compared to 2020 and included favorable changes in foreign exchange rates of $12.5 million. The increase in net sales was primarily due to higher volume across all segments and businesses compared to 2020 that had production disruptions due to the impact of COVID-19. Americas Net sales in the Americas increased $236.5 million, or 51.7%, in 2021 compared to 2020 and included favorable changes in foreign exchange rates of $0.7 million. The increase in net sales was primarily due to incremental sales from the Hartland and Carling acquisitions, higher volume across all segments and businesses compared to 2020 that had production disruptions due to the impact of COVID-19. Europe European net sales increased $112.5 million, or 35.4%, in 2021 compared to 2020 and included favorable changes in foreign exchange rates of $14.2 million. The increase in net sales was primarily due to higher volume across all businesses within the Electronics and Transportation segments compared to the 2020 that had production disruptions due to the impact of COVID-19. 32 RESULTS OF OPERATIONS FOR THE YEAR ENDED DECEMBER 26, 2020 AS COMPARED TO THE YEAR ENDED DECEMBER 28, 2019 The fiscal year 2020 included approximately $44.0 million of non-segment charges, of which $2.3 million of charges are acquisition-related and integration charges related to the IXYS acquisition and other contemplated acquisitions. In addition, there were $41.7 million of restructuring, impairment and other charges, primarily related to the goodwill impairment charge of $33.8 million recorded in the second quarter associated with the automotive sensors reporting unit within the Transportation segment, employee termination costs of $5.5 million, $2.2 million of impairment charges recorded in the first quarter associated with the announced consolidation of a manufacturing facility within the Industrial segment and other restructuring charges of $0.2 million. See Note 8, Restructuring, Impairment and Other Charges, for further discussion. The fiscal year 2019 included approximately $21.9 million of non-segment charges, of which $8.9 million of charges are acquisition-related and integration charges primarily related to the IXYS acquisition and other contemplated acquisitions, and $13.0 million of restructuring charges primarily related to employee termination costs. Fiscal year 2020 also included approximately $14.9 million in foreign currency exchange gains primarily attributable to changes in the value of the Euro, Philippine peso, and Chinese renminbi against the U.S. dollar, while fiscal year 2019 included approximately $5.2 million in foreign currency exchange losses primarily attributable to changes in the value of the Euro, Chinese renminbi, and Japanese yen against the U.S. dollar.

These decreases were primarily driven by the production disruption due to temporary closures of manufacturing facilities resulting from government directives due to the impact of COVID-19 and a decline in global auto production driven by the temporary closures of customer manufacturing facilities during the first half of 2020. These sales declines were partially offset by increases in customer demand for consumer devices for work from home needs and strength in various end market demand across all businesses in the second half of the year. All businesses within the Transportation segment experienced lower sales in 2020 due to the production disruptions in the first half of 2020 mentioned above, which was partially offset in the second half of the year, driven by stronger end market demand. Cost of Sales Cost of sales was $944.5 million, or 65.3% of net sales, in 2020, compared to $957.6 million, or 63.7% of net sales, in 2019. The decrease in cost of sales was primarily due to lower volume in the Electronics and Transportation segments driven by the factors discussed above. As a percent of net sales, cost of sales increased 1.6% driven by higher freight costs of $5.6 million, additional costs associated with government-directed plant shutdowns and supply chain constraints, supplies and other costs due to the impact of COVID-19, and unfavorable product mix. Gross Profit Gross profit was $501.2 million, or 34.7% of net sales, in 2020, compared to $546.3 million, or 36.3% of net sales, in 2019. The decrease of $45.1 million in gross profit reflected lower volume across all segments driven by the disruption across all segments 33 due to temporary closures of manufacturing facilities in the first half of the year resulting from government directives due to the impact of COVID-19. The decrease in gross margin of 1.6% was primarily from the lower volume mentioned previously, unfavorable price and product mix primarily in the Industrial segment. Additionally, higher freight cost of $5.6 million, costs associated with government-directed plant shutdowns and supply chain constraints, supplies and other costs due to the impact of COVID-19 negatively impacted gross margins. Operating Expenses Total operating expenses were $338.8 million, or 23.4% of net sales, for 2020 compared to $353.5 million, or 23.5% of net sales, for 2019. The decrease in operating expenses of $14.7 million is primarily due to lower research and development expenses of $27.5 million, or 1.7% of net sales, a reduction in discretionary expenses including travel and marketing expenses and a $6.6 million reduction in acquisition-related and integration charges, partially offset by the second quarter goodwill impairment charge of $33.8 million, or 2.3% of net sales, in the automotive sensors reporting unit within the Transportation segment and impairment charges of $2.2 million related to the Company’s first quarter announcement to consolidate a manufacturing facility within the Industrial segment. Operating Income Operating income for 2020 was $162.4 million, a decrease of $30.4 million or 15.8% compared to $192.8 million for 2019. The decrease in operating income is primarily due to lower gross margin across all segments and the $33.8 million goodwill impairment charge noted above partially offset by a reduction in operating expenses described above. Operating margins decreased from 12.8% in 2019 to 11.2% in 2020 primarily driven by the factors mentioned above. The second quarter goodwill impairment charge of $33.8 million negatively impacted the 2020 operating margin by 2.3% which was partially offset by the lower operating expenses and cost reductions noted above. Income Before Income Taxes Income before income taxes for 2020 was $161.3 million, or 11.2% of net sales compared to $165.9 million, or 11.0% of net sales, for 2019. In addition to the factors impacting comparative results for operating income discussed above, income before income taxes benefited from foreign exchange gains of $14.9 million during the fiscal year ended December 26, 2020 compared to foreign exchange losses of $5.2 million during the fiscal year ended December 28, 2019. Additionally, the increase in other income of $4.5 million was primarily due to the 2019 fiscal year impairment charges of $7.3 million for certain other investments and a $2.6 million loss on the disposal of a business within the Electronics segment and $1.7 million increase in unrealized investment gains associated with our equity investments, partially offset by lower interest income of $2.0 million and a $1.2 million increase in coal mining reserves in 2020 versus 2019. Income Taxes Income tax expense for 2020 was $31.3 million, or an effective tax rate of 19.4% compared to income tax expense of $26.8 million, or an effective tax rate of 16.2% for 2019. The Company’s tax rates are lower than the applicable U.S. statutory tax rate primarily due to income earned in lower tax jurisdictions, partially offset by the impact of taxes on unremitted earnings, the GILTI tax provisions, and non-U.S. losses and expenses with no tax benefit. Changes in the amount of these items from year to year impact the effective tax rates. In addition, the 2020 income tax expense included the impact of the goodwill impairment charge of $33.8 million that was recorded in the second quarter of 2020, the substantial majority of which related to non-U.S. entities and did not result in a tax benefit, and the 2019 income tax expense included a benefit of $3.3 million from the recognition of previously unrecognized tax benefits (and the reversal of the related accrued interest) due to a lapse in the statute of limitations. The impact of the items discussed above resulted in an increase in the effective tax rate in 2020, as compared to the effective tax rate in 2019. Further information regarding these items is provided in Note 14, Income Taxes, of the Notes to Consolidated Financial Statements included in this Annual Report. Segment Information The Company reports its operations by the following segments: Electronics, Transportation and Industrial. Segment information is described more fully in Note 16, Segment Information, of the Notes to Consolidated Financial Statements included in this Annual Report. The following table is a summary of the Company’s net sales by segment: 34 (in millions) Electronics Transportation Industrial Total Electronics Segment Fiscal Year 2020 2019 Change % Change $ $ 937.7 $ 395.8 112.2 1,445.7 $ 961.1 $ 428.5 114.3 1,503.9 $ (23.4) (32.7) (2.1) (58.2) (2.4) % (7.6) % (1.8) % (3.9) % Net sales for the Electronics segment decreased $23.4 million, or 2.4%, in 2020 compared to 2019 primarily due to declines in net sales for the semiconductor and electronics products businesses of $17.5 million and $5.9 million, respectively, driven by the production disruption due to temporary closures of manufacturing facilities resulting from government directives due to the impact of COVID-19 during the first half of the year. These declines were partially offset by increases in customer demand for consumer devices for work from home needs and strength in various end markets during the second half of the year along with favorable changes in foreign exchange rates of $3.6 million. Transportation Segment Net sales in the Transportation segment decreased $32.7 million, or 7.6%, in 2020 compared to 2019 due to decreased volume in passenger car products, commercial vehicle products, and automotive sensors businesses of $18.1 million, $10.6 million, and $4.0 million, respectively, driven by the production disruption due to temporary closures of manufacturing facilities resulting from government directives due to the impact of COVID-19 and a decline in global auto production driven by the temporary closures of customer manufacturing facilities during the first half of 2020. These sales declines were partially offset by increases in end market demand across all businesses in the second half of 2020 and favorable changes in foreign exchange rates of $4.1 million. Industrial Segment The Industrial segment net sales decreased slightly by $2.1 million, or 1.9%, in 2020 compared to 2019 primarily due to decreased volume across all businesses driven by the production disruption due to temporary closures of manufacturing facilities resulting from government directives due to the impact of COVID-19 in the first half of 2020, partially offset by the transfer of the temperature sensor product line in the third quarter of 2020 previously reported in the Electronics segment. Geographic Net Sales Information Net sales by geography represent net sales to customer or distributor locations. The following table is a summary of the Company’s net sales by geography: (in millions) Asia-Pacific Americas Europe Total Asia-Pacific Fiscal Year 2020 2019 Change % Change $ $ 670.5 $ 457.8 317.4 1,445.7 $ 656.8 $ 508.4 338.7 1,503.9 $ 13.7 (50.6) (21.3) (58.2) 2.1 % (10.0) % (6.3) % (3.9) % Asia-Pacific net sales increased $13.7 million, or 2.1%, in 2020 compared to 2019. The increase in net sales was primarily due to higher volume in the semiconductor business within the Electronics segment and favorable changes in foreign exchange rates of $2.2 million, partially offset by lower volume in the passenger car products business within the Transportation segment due to the production disruption associated with temporary closures of manufacturing facilities resulting from government directives due to the impact of COVID-19 in the first half of 2020. Americas 35 Net sales in the Americas decreased $50.6 million, or 10.0%, in 2020 compared to 2019 primarily due to lower volume across all segments driven by the production disruption due to temporary closures of manufacturing facilities resulting from government directives due to the impact of COVID-19, the temporary closures of customer manufacturing facilities during the first half of 2020 and unfavorable changes in foreign exchange rates of $0.3 million. These sales declines were partially offset by increases in end market demand across all businesses in the second half of the year. Europe European net sales decreased $21.3 million, or 6.3%, in 2020 compared to 2019. The decrease in net sales was primarily due to lower volume in the semiconductor business within the Electronics segment, lower volume in passenger car products and commercial vehicle products businesses within the Transportation segment driven by the production disruption due to temporary closures of manufacturing facilities resulting from government directives due to the impact of COVID-19 and the temporary closures of customer manufacturing facilities during the first half of 2020, partially offset by increased volume in the second half of 2020 due to higher end market demand in Electronics and Transportation businesses and favorable changes in foreign exchange rates of $5.8 million. Liquidity and Capital Resources Cash and cash equivalents were $478.5 million as of January 1, 2022, a decrease of $209.1 million as compared to December 26, 2020. As of January 1, 2022, $326.1 million of the Company's $478.5 million cash and cash equivalents was held by non-U.S. subsidiaries. Of the $326.1 million, at least $171.2 million can be repatriated with minimal tax consequences, although in certain cases a non-U.S. withholding tax would be payable but subsequently refunded. With respect to the remaining $154.9 million, the Company has recognized deferred tax liabilities on approximately $68.6 million as of January 1, 2022 because the amounts are not considered to be permanently reinvested, and the Company may access additional amounts through loans and other means. Repatriation of some non-U.S. cash balances is restricted by local laws. Management regularly evaluates whether foreign earnings are expected to be permanently reinvested. This evaluation requires judgment about the future operating and liquidity needs of the Company and its foreign subsidiaries. Changes in economic and business conditions, non- U.S. or U.S. tax laws could result in changes to these judgments and the need to record additional tax liabilities. The Company has historically supported its liquidity needs through cash flows from operations. Management expects that the Company’s (i) current level of cash, cash equivalents, and marketable securities, (ii) current and forecasted cash flows from operations, (iii) availability under existing funding arrangements, and (iv) access to capital in the capital markets will provide sufficient funds to support the Company’s operations, capital expenditures, investments, and debt obligations on both a short- term and long-term basis. Revolving Credit Facility On April 3, 2020, the Company amended its existing credit agreement to effect certain changes, including, among others: (i) eliminating the $200.0 million unsecured term loan credit facility, the remaining outstanding balance ($140.0 million) of which was repaid in full on April 3, 2020 through the revolving credit facility; (ii) making certain financial and non-financial covenants less restrictive on the Company; (iii) modifying performance-based interest rate margins and undrawn fees; and (iv) extending the maturity date to April 3, 2025. The amended Credit Agreement also allows the Company to increase the size of the revolving credit facility or enter into one or more tranches of term loans if there is no event of default and the Company is in compliance with certain financial covenants. The Company made payments of $30.0 million on the amended revolving credit facility during the fiscal year ended January 1, 2022. The balance under the facility was $100.0 million as of January 1, 2022. Outstanding borrowings under the amended credit agreement bear interest, at the Company’s option, at either LIBOR, fixed for interest periods of one, two, three or six-month periods, plus 1.25% to 2.00%, or at the bank’s Base Rate, as defined, plus 0.25% to 1.00%, based upon the Company’s Consolidated Leverage Ratio, as defined. The Company is also required to pay commitment fees on unused portions of the credit agreement ranging from 0.125% to 0.20%, based on the Consolidated Leverage Ratio, as defined in the agreement. The credit agreement includes representations, covenants and events of default that are customary for financing transactions of this nature. The effective interest rate on outstanding borrowings under the credit facility was 1.35% at January 1, 2022. As of January 1, 2022, the Company had no outstanding in letters of credit and had available $600.0 million of borrowing capacity under the revolving credit facility. At January 1, 2022, the Company was in compliance with all covenants under the credit agreement. 36 Senior Notes On December 8, 2016, the Company entered into a Note Purchase Agreement, pursuant to which the Company issued and sold €212 million aggregate principal amount of senior notes in two series.

The net cash payment of $313.6 million was funded by the Company’s cash on hand. Cash Flow Overview Operating cash inflows are largely attributable to sales of the Company’s products. Operating cash outflows are largely attributable to recurring expenditures for raw materials, labor, rent, interest, taxes and other operating activities. The following describes the Company’s cash flows for the fiscal year ended January 1, 2022 and December 26, 2020: 37 (in millions) Net cash provided by operating activities Net cash used in investing activities Net cash used in financing activities Effect of exchange rate changes on cash, cash equivalents, and restricted cash (Decrease) increase in cash, cash equivalents, and restricted cash Cash, cash equivalents, and restricted cash at beginning of period Cash, cash equivalents, and restricted cash at end of period Cash Flow from Operating Activities Fiscal Year 2021 2020 $ $ 373.3 $ (499.2) (69.0) (9.9) (204.7) 687.5 482.8 $ 258.0 (51.4) (67.8) 17.6 156.4 531.1 687.5 Net cash provided by operating activities was $373.3 million for the fiscal year 2021, an increase of $115.3 million, compared to $258.0 million during the fiscal year 2020. The increase in net cash provided by operating activities was primarily due to higher cash earnings partially offset by increases in working capital resulting from higher sales growth. Cash Flow from Investing Activities Net cash used in investing activities was $499.2 million for the fiscal year 2021, compared to $51.4 million during the fiscal year 2020. Capital expenditures were $90.6 million, representing a decrease of $34.4 million compared to the fiscal year 2020. Net cash paid for the Hartland and Carling acquisitions was $422.1 million during the fiscal year 2021.

The following describes the Company’s cash flows for the twelve months ended December 26, 2020 and December 28, 2019: (in millions) Net cash provided by operating activities Net cash used in investing activities Net cash used in financing activities Effect of exchange rate changes on cash, cash equivalents, and restricted cash Increase in cash, cash equivalents, and restricted cash Cash, cash equivalents, and restricted cash at beginning of period Cash, cash equivalents, and restricted cash at end of period Cash Flow from Operating Activities 38 Fiscal Year 2020 2019 258.0 $ (51.4) (67.8) 17.6 156.4 531.1 687.5 $ 245.3 (56.4) (146.3) (1.2) 41.4 489.7 531.1 $ $ Net cash provided by operating activities was $258.0 million for the fiscal year 2020, compared to $245.3 million during the fiscal year 2019. The increase in net cash provided by operating activities was primarily due to lower annual incentive payments and favorable changes in net working capital partially offset by lower earnings largely due to the impact of COVID-19. Cash Flow from Investing Activities Net cash used in investing activities was $51.4 million for the fiscal year 2020, compared to $56.4 million during the fiscal year 2019. Capital expenditures were $56.2 million, representing a decrease of $5.7 million compared to the fiscal year 2019.

Recent Accounting Pronouncements Recently issued accounting standards and their estimated effect on the Company’s Consolidated Financial Statements are described in Note 1, Summary of Significant Accounting Policies and Other Information, of the Notes to Consolidated Financial Statements. 40 ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK. The Company is exposed to market risk from changes in interest rates, foreign exchange rates and commodity prices. Interest Rates Risk The Company made payments of $30.0 million on the amended revolving credit facility during the fiscal year 2021. The balance under the facility was $100.0 million as of January 1, 2022. With variable interest rates, the Company is subject to future interest rate fluctuations in relation to these borrowings which could potentially have a negative impact on cash flows of the Company. A prospective increase of 100 basis points in the interest rate applicable to the Company’s outstanding borrowings under its credit facility would result in an increase of approximately $1.0 million in annual interest expense. This exposure would be partially if not fully offset by higher interest income from the Company's investments. The Company is not party to any currency exchange or interest rate protection agreements as of January 1, 2022. Foreign Exchange Rate Risk The majority of the company’s operations consist of manufacturing and sales activities in foreign countries. The Company has operations in China, Germany, Mexico, Philippines, U.K., Japan, Lithuania, Netherlands, Portugal, Singapore, South Korea, Spain, and the U.S. During 2021, sales to customers outside the U.S. were approximately 69% of total net sales. During 2020, sales to customers outside the U.S. were approximately 73% of total net sales. Substantially all sales in Europe are denominated in euros and substantially all sales in the Asia-Pacific region are denominated in U.S. dollars, Chinese renminbi, Japanese yen, or Korean won. The company’s foreign exchange exposures result primarily from inter-company loans, external borrowings, sale of products in foreign currencies, foreign currency denominated purchases, employee-related and other costs of running operations in foreign countries. The company’s most significant foreign currency exposures are to the euro, the Chinese renminbi, Mexican peso, and Philippine peso. Changes in foreign exchange rates could affect the company’s sales, costs, balance sheet values and earnings. At January 1, 2022, the net value of the Company’s assets with exposure to foreign currency risk was approximately $148 million, with the largest exposure being a Japanese yen denominated inter-company loan with a Euro functional currency subsidiary. The reduction in earnings from a hypothetical instantaneous 10% adverse change in quoted foreign currency spot rates applied to foreign currency sensitive asset instruments would be $15 million at January 1, 2022. At January 1, 2022, the net value of the Company’s liabilities with exposure to foreign currency risk was $389 million, with the largest exposure being U.S. Dollar denominated inter-company loans with a Euro functional currency subsidiary. The reduction in earnings from a hypothetical instantaneous 10% adverse change in quoted foreign currency spot rates applied to foreign currency sensitive liability instruments would be $39 million at January 1, 2022. As a result of the mix in currencies impacting the hypothetical 10% changes, the movements in some instruments would offset movements in other instruments reducing the hypothetical exposure to the Company. Commodity Price Risk The Company uses various metals in the manufacturing of its products, including copper, zinc, tin, gold, and silver. Prices of these and other commodities can rise and result in materially higher costs of producing our products. The Company believes it has adequate primary and secondary sources of supply for each of our key materials. While the Company is exposed to significant changes in certain metal prices and expects higher material costs, the Company actively monitors these exposures and may take various actions, including price increases and productivity improvements to mitigate any negative impacts of these exposures. Due to the continued impact from COVID-19, transportation costs increased significantly in 2021 and may further increase in 2022. The Company has taken and, in the future, may take further various actions, including price increases and changing freight modes or other alternative solutions to mitigate the impact of rising transportation costs. 41  ITEM 8.

Opinion on the financial statements We have audited the accompanying consolidated balance sheets of Littelfuse, Inc. (a Delaware corporation) and subsidiaries (the “Company”) as of January 1, 2022 and December 26, 2020, the related consolidated statements of net income, comprehensive income, equity, and cash flows for each of the three years in the period ended January 1, 2022, and the related notes and financial statement schedule 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 January 1, 2022 and December 26, 2020, and the results of its operations and its cash flows for each of the three years in the period ended January 1, 2022, 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 January 1, 2022, 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 17, 2022 expressed an unqualified opinion. 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 January 1, 2022, 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 17, 2022, 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 regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion. Critical audit 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. Business Acquisition – Carling Technologies – Valuation of acquired Intangible Assets As discussed in Note 2, the Company acquired Carling Technologies, Inc., on November 30, 2021 for a total purchase price of approximately $314 million, net of cash acquired. The Company allocated the purchase price, on a preliminary basis, to the assets acquired and liabilities assumed based on their respective fair values, including identified intangible assets of $125.9 million. We identified the valuation of acquired intangible assets as a critical audit matter. The principal considerations for our determination that the valuation of acquired intangible assets is a critical audit matter are (i) the significant judgment by management when determining assumptions used in the fair value measurement of acquired intangible assets (ii) the high degree of auditor judgment and subjectivity in performing procedures and evaluating 43 management’s significant assumptions relating to revenue growth, royalty rates, and customer attrition rates and (iii) the audit effort involved the use of professionals with specialized skill and knowledge. Our audit procedures related to the valuation of the acquired intangible assets included the following, among others: – we tested the design and operating effectiveness of the controls over the Company’s acquisition and valuation process, including review of the valuation model, significant assumptions used, and the completeness and accuracy of the underlying data used – we tested the forecasted revenues and cash flows by assessing the reasonableness of management’s forecasts compared to historical results and forecasted industry trends – with the assistance of our valuation specialists, we assessed the royalty, customer attrition, and revenue growth rates by developing a range of independent estimates and comparing those to the rates selected by management. We also involved our valuation specialists to evaluate the assumptions and methodologies used in valuing the intangible assets. /s/ GRANT THORNTON LLP We have served as the Company’s auditor since 2014. Southfield, Michigan February 17, 2022 44 Report of Independent Registered Public Accounting Firm Board of Directors and Shareholders Littelfuse, Inc. Opinion on internal control over financial reporting We have audited the internal control over financial reporting of Littelfuse, Inc. (a Delaware corporation) and subsidiaries (the “Company”) as of January 1, 2022, based on criteria established in the 2013 Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission ("COSO"). In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of January 1, 2022, based on criteria established in the 2013 Internal Control—Integrated Framework issued by COSO. We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (“PCAOB”), the consolidated financial statements of the Company as of and for the year ended January 1, 2022, and our report dated February 17, 2022 expressed an unqualified opinion on those financial statements. Basis for opinion The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control over Financial Reporting (“Management’s Report”). Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. 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 audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion. Our audit of, and opinion on, the Company’s internal control over financial reporting does not include the internal control over financial reporting of Carling Technologies, Inc., a wholly-owned subsidiary, whose financial statements reflect total assets and revenues constituting 5% and 1%, respectively, of the related consolidated financial statement amounts as of and for the year ended January 1, 2022. As indicated in Management’s Report, Carling Technologies, Inc. was acquired during 2021. Management’s assertion on the effectiveness of the Company’s internal control over financial reporting excluded internal control over financial reporting of Carling Technologies, Inc. Definition and limitations of internal control over financial reporting A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the Company are being made only in accordance with authorizations of management and directors of the Company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the Company’s assets that could have a material effect on the financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. /s/ GRANT THORNTON LLP Southfield, Michigan February 17, 2022 45 LITTELFUSE, INC.

Summary of Significant Accounting Policies and Other Information Nature of Operations Littelfuse, Inc. and subsidiaries (the “Company”) is an industrial technology manufacturing company empowering a sustainable, connected, and safer world. Across more than 15 countries, and with approximately 17,000 global associates, the company partners with customers to design and deliver innovative, reliable solutions. Serving over 100,000 end customers, the company’s products are found in a variety of industrial, transportation and electronics end markets – everywhere, every day. Fiscal Year References herein to “2021”, “fiscal 2021” or “fiscal year 2021” refer to the fiscal year ended January 1, 2022. References herein to “2020”, “fiscal 2020” or “fiscal year 2020” refer to the fiscal year ended December 26, 2020. References herein to “2019”, “fiscal 2019” or “fiscal year 2019” refer to the fiscal year ended December 28, 2019. The Company operates on a 52-53 week fiscal year (4-4-5 basis) ending on the Saturday closest to December 31. Therefore, the financial results of certain fiscal years and the associated 14 week quarters will not be exactly comparable to the prior 52 week fiscal years and the associated quarters having only 13 weeks. As a result of using this convention, the fiscal year 2021 contained 53 weeks while each of fiscal 2020 and fiscal 2019 contained 52 weeks. Basis of Presentation The Consolidated Financial Statements include the accounts of Littelfuse, Inc. and its subsidiaries. All significant intercompany accounts and transactions have been eliminated. The Company’s Consolidated Financial Statements were prepared in accordance with generally accepted accounting principles in the United States of America ("U.S.") and include the assets, liabilities, sales and expenses of all wholly-owned subsidiaries and majority-owned subsidiaries over which the Company exercises control. Use of Estimates The process of preparing financial statements in conformity with generally accepted accounting principles in the U.S. requires management to make estimates and assumptions that affect the amounts of assets and liabilities at the date of the Consolidated Financial Statements, and the reported amounts of revenues and expenses and the accompanying notes. The Company evaluates and updates its assumptions and estimates on an ongoing basis and may employ outside experts to assist in its evaluation, as considered necessary. Actual results could differ from those estimates. Cash, Cash Equivalents and Restricted Cash All highly liquid investments, with an original maturity of three months or less when purchased, are considered to be cash equivalents. The Company maintains several pools including multicurrency notional pools and physical pools internationally and a zero balance account ("ZBA") structure in the U.S. In the notional pools, actual cash balances are not physically converted and are not commingled between participating legal entities. The Company will classify any overdraft balances within accrued expenses and other current liabilities on the Consolidated Balance Sheets. The following table provides a reconciliation of cash, cash equivalents and restricted cash at January 1, 2022 and December 26, 2020 reported within the Consolidated Balance Sheets that sum to the total of the same such amounts shown in the Consolidated Statement of Cash Flows. (in millions) Cash and cash equivalents Restricted cash included in prepaid expenses and other current assets Restricted cash included in other assets Total cash, cash equivalents and restricted cash Short-Term and Long-Term Investments 2021 2020 478,473 $ 687,525 2,718 1,645 $ — — 482,836 $ 687,525 $ $ 51 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS As of January 1, 2022, the Company has an investment in Polytronics Technology Corporation Ltd. (“Polytronics”). The Company’s Polytronics shares held at the end of fiscal 2021 and 2020 represent approximately 6.8% and 7.2% of total Polytronics shares outstanding, respectively. The Polytronics investment is carried at fair value. The fair value of the Polytronics investment was €23 million (approximately $26.1 million) at January 1, 2022 and €15.7 million (approximately $19.2 million) at December 26, 2020. As a result of the Company’s acquisition of IXYS, the Company has equity ownerships in various investments that are accounted for under the equity method. The Company owns 45% of the outstanding equity of Powersem GmbH, a module manufacturer based in Germany, approximately 19% of the outstanding equity of EB Tech Ltd., a company with expertise in radiation technology based in South Korea, and approximately 24% of the outstanding common shares of Automated Technology, Inc., a supplier located in the Philippines that provides assembly and test services. All equity-level investments are less than majority owned. The Company recognized $1.3 million gains from its equity method investment for the fiscal year ended January 1, 2022. The Company recognized no gains and losses from its equity method investments for the fiscal year ended December 26, 2020. The balance of these equity method investments was $12.4 million and $11.4 million as of the fiscal years ended January 1, 2022 and December 26, 2020, respectively. See Note 18, Related Party Transactions, for further discussion. The Company does not have any remaining book value of investments accounted for under the cost method as of January 1, 2022. As of December 26, 2020, the Company had a net book value of $0.5 million. During the fiscal year ended January 1, 2022, the Company impaired the remaining book value of these investments and recorded an impairment charge of $0.5 million, and during the fiscal year ended December 26, 2020, the Company recorded $0.1 million in Other expense (income), net in the Consolidated Statements of Net Income. See Note 10, Fair Value of Assets and Liabilities, for further discussion. The Company has investments related to its non-qualified Supplemental Retirement and Savings Plan. The Company maintains accounts for participants through which participants make investment elections. The investment securities are subject to the claims of the Company’s creditors. The investment securities are all mutual funds. The investment securities are measured at net asset value. As of January 1, 2022 and December 26, 2020, the investment securities balance was $15.0 million and $13.2 million, respectively, related to the plan and are included in Other assets on the Consolidated Balance Sheets. Trade Receivables The Company performs credit evaluations of customers’ financial condition and generally does not require collateral. Credit losses are provided for in the financial statements based upon specific knowledge of a customer’s inability to meet its financial obligations to the Company. Historically, credit losses have consistently been within management’s expectations and have not been a material amount. A receivable is considered past due if payments have not been received within agreed upon invoice terms. Write-offs are recorded at the time a customer receivable is deemed uncollectible. The Company also maintains allowances against trade receivables for the settlement of rebates and sales discounts to customers. These allowances are based upon specific customer sales and sales discounts as well as actual historical experience. Inventories Inventories are stated at the lower of cost or net realizable value, which approximates current replacement cost. Cost is principally determined using the first-in, first-out method. The Company maintains excess and obsolete reserves against inventory to reduce the carrying value to the expected net realizable value. These reserves are based upon a combination of factors including historical sales volume, market conditions, lower of cost or market analysis and expected realizable value of the inventory. Property, Plant, and Equipment Land, buildings, and equipment are carried at cost. Depreciation is calculated using the straight-line method with useful lives of up to 21 years for buildings, three to ten years for equipment, seven years for furniture and fixtures, five years for tooling and three years for computer equipment. Leasehold improvements are depreciated over the lesser of their useful life or the lease term. Maintenance and repair costs are charged to expense as incurred. Major overhauls that extend the useful lives of existing assets are capitalized. Goodwill 52 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS The Company annually tests goodwill for impairment on the first day of its fiscal fourth quarter, or more frequently if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying value. The Company compares each reporting unit’s fair value, estimated based on comparable company market valuations and expected future discounted cash flows to be generated by the reporting unit, to its carrying value. The results of the annual goodwill impairment test as of September 26, 2021 indicated that the estimated fair values for each of the seven reporting units exceeded their respective carrying values. As of the most recent annual test conducted on September 26, 2021, the Company noted that the excess of fair value over the carrying value, was 380%, 104%, 255%, 217%, 95%, 144%, and 231% for its reporting units; Electronics-Passive Products and Sensors, Electronics-Semiconductor, Passenger Car Products, Commercial Vehicle Products, Automotive Sensors, Relays, and Power Fuse, respectively. Relatively small changes in the Company’s key assumptions would not have resulted in any reporting units failing the goodwill impairment test. See Note 5, Goodwill and Other Intangible Assets, for additional information. During the second quarter of 2020, the Company recorded a non-cash charge of $33.8 million to recognize the impairment of goodwill in the automotive sensors reporting unit within the Transportation segment. The goodwill impairment charge was due to reductions in the estimated fair value for the automotive sensors reporting unit based on lower expectations for future revenue, profitability and cash flows as compared to the expectations of the 2019 annual goodwill impairment test. These lower future expectations were driven by projected extended declines in end market demand due to the COVID-19 pandemic. In addition, during the second quarter of 2020, certain customers notified the Company of their decision to delay future programs along with a customer canceling an existing program. As of January 1, 2022, the automotive sensors reporting unit had $9.2 million of remaining goodwill. The Company also performs an interim review for indicators of impairment each quarter to assess whether an interim impairment review is required for any reporting unit. As part of its interim reviews, management analyzes potential changes in the value of individual reporting units based on each reporting unit’s operating results for the period compared to expected results as of the prior year’s annual impairment test. In addition, management considers how other key assumptions, including discount rates and expected long-term growth rates, used in the last annual impairment test, could be impacted by changes in market conditions and economic events. Based on the interim assessments as of January 1, 2022, management concluded that no events or changes in circumstances indicated that it was more likely than not that the fair value for any reporting unit had declined below its carrying value. Long-Lived Assets Customer relationships, trademarks and tradenames are amortized using the straight-line method over estimated useful lives that have a range of 5 to 20 years. Patents, licenses and software are amortized using the straight-line method or an accelerated method over estimated useful lives that have a range of 5 to 17 years. The distribution networks are amortized on either a straight-line or accelerated basis over estimated useful lives that have a range of 4 to 10 years. Land use rights are amortized using the straight-line method over 50 years which is the term of the land use rights. The Company assesses potential impairments to its long-lived assets if events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. An impaired asset is written down to its estimated fair value based upon the most recent information available. Estimated fair market value is generally measured by discounting estimated future cash flows. Long-lived assets, other than goodwill and other intangible assets, that are held for sale are recorded at the lower of carrying value or the fair market value less the estimated cost to sell. Environmental Liabilities Environmental liabilities are accrued based on engineering studies estimating the cost of remediating sites. Expenses related to on-going maintenance of environmental sites are expensed as incurred. If actual or estimated probable future losses exceed the Company’s recorded liability for such claims, the Company would record additional charges during the period in which the actual loss or change in estimate occurred. Pension and Other Post-retirement Benefits The Company records annual income and expense amounts relating to its pension and post-retirement benefits plans based on calculations which include various actuarial assumptions including discount rates, expected long-term rates of return and compensation increases. The Company reviews its actuarial assumptions on an annual basis as of the fiscal year-end balance sheet date (or more frequently if a significant event requiring remeasurement occurs) and modifies the assumption based on 53 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS current rates and trends when it is appropriate to do so. The effects of modifications are recognized immediately on the Consolidated Balance Sheets, but are generally amortized into operating earnings over future periods, with the deferred amount recorded in accumulated other comprehensive income (loss). The Company believes that the assumptions utilized in recording its obligations under its plans are reasonable based on its experience, market conditions and input from its actuaries and investment advisors. Revenue Recognition Revenue Disaggregation The following table disaggregates the Company’s revenue by primary business units for the fiscal years ended January 1, 2022 and December 26, 2020: (in thousands) Electronics Segment Fiscal Year Ended January 1, 2022 Transportation Segment (1) Industrial Segment Total Electronics – Semiconductor $ 678,861 $ Electronics – Passive Products and Sensors 621,883 Passenger Car Products Commercial Vehicle Products Automotive Sensors Industrial Products Total (in thousands) Passenger Car Products Commercial Vehicle Products Automotive Sensors Industrial Products Total (1) Formerly known as Automotive segment. — $ — 266,020 160,300 101,738 — $ — — — — — 251,126 678,861 621,883 266,020 160,300 101,738 251,126 $ 1,300,744 $ 528,058 $ 251,126 $ 2,079,928 Fiscal Year Ended December 26, 2020 Electronics Segment Transportation Segment (1) Industrial Segment Total — 200,455 101,324 93,985 — — — — — 112,169 522,352 415,410 200,455 101,324 93,985 112,169 $ 937,762 $ 395,764 $ 112,169 $ 1,445,695 — — — — — — — — Electronics – Semiconductor $ 522,352 $ — $ — $ Electronics – Passive Products and Sensors 415,410 See Note 16, Segment Information, for net sales by segment and countries. The Company recognizes revenue on product sales in the period in which the Company satisfies its performance obligation and control of the product is transferred to the customer. The Company’s sales arrangements with customers are predominately short term in nature and generally provide for transfer of control at the time of shipment as this is the point at which title and risk of loss of the product transfers to the customer. At the end of each period, for those shipments where title to the products and the risk of loss and rewards of ownership do not transfer until the product has been received by the customer, the Company adjusts revenues and cost of sales for the delay between the time that the products are shipped and when they are received by the customer. The amount of revenue recorded reflects the consideration to which the Company expects to be entitled in exchange for goods and may include adjustments for customer allowance, rebates and price adjustments. The Company’s distribution channels are primarily through direct sales and independent third-party distributors. The Company has elected the practical expedient under Accounting Standards Codification ("ASC") 340-40-25-4 to expense commissions when incurred as the amortization period of the commission asset the Company would have otherwise recognized is less than one year. Revenue and Billing 54 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS The Company generally accepts orders from customers through receipt of purchase orders or electronic data interchange based on written sales agreements and purchasing contracts. Contract pricing and selling agreement terms are based on market factors, costs, and competition. Pricing is often negotiated as an adjustment (premium or discount) from the Company’s published price lists. The customer is invoiced when the Company’s products are shipped to them in accordance with the terms of the sales agreement. As the Company’s standard payment terms are less than one year, the Company has elected the practical expedient under ASC 606-10-32-18 to not assess whether a contract has a significant financing component. The Company also elected the practical expedient provided in ASC 606-10-25-18B to treat all product shipping and handling activities as fulfillment activities, and therefore recognize the gross revenue associated with the contract, inclusive of any shipping and handling revenue. Ship and Debit Program Some of the terms of the Company’s sales agreements and normal business conditions provide customers (distributors) the ability to receive price adjustments on products previously shipped and invoiced. This practice is common in the industry and is referred to as a “ship and debit” program. This program allows the distributor to debit the Company for the difference between the distributors’ contracted price and a lower price for specific transactions. Under certain circumstances (usually in a competitive situation or large volume opportunity), a distributor will request authorization for pricing allowances to reduce its price. When the Company approves such a reduction, the distributor is authorized to “debit” its account for the difference between the contracted price and the lower approved price. The Company establishes reserves for this program based on historic activity, electronic distributor inventory levels and actual authorizations for the debit and recognizes these debits as a reduction of revenue. Return to Stock The Company has a return to stock policy whereby certain customers, with prior authorization from the Company's management, can return previously purchased goods for full or partial credit. The Company establishes an estimated allowance for these returns based on historic activity. Sales revenue and cost of sales are reduced to anticipate estimated returns. Volume Rebates The Company offers volume-based sales incentives to certain customers to encourage greater product sales. If customers achieve their specific quarterly or annual sales targets, they are entitled to rebates. The Company estimates the projected amount of rebates that will be achieved by the customer and recognizes this estimated cost as a reduction to revenue as products are sold. Allowance for Doubtful Accounts The Company currently measures the expected credit losses based on our historical credit loss experience. The Company has not experienced significant recent or historical credit losses and is not forecasting any significant credit losses which would require adjustments to our methodology. If current conditions and supportable forecasts indicate that our historical loss experience is not reasonable and no longer supportable, the Company may adjust its historical credit loss experience and to reflect these conditions and forecasts. The Company regularly analyzes its significant customer accounts and, when the Company becomes aware of a customer’s inability to meet its financial obligations, the Company records a specific reserve for bad debt to reduce the related receivable to the amount the Company reasonably believes is collectible. The Company also analyzes all other customers based on a variety of factors including the length of time the receivables are past due, the financial health of the customer, macroeconomic considerations and historical collection and loss experience. Historically, the allowance for doubtful accounts has been adequate to cover bad debts. If circumstances related to specific customers change, the estimates of the recoverability of receivables could be further adjusted. As of January 1, 2022 and December 26, 2020, the Company’s allowance for doubtful accounts was $1.9 million and $1.4 million, respectively. Additionally, the Company had $2.1 million and $1.0 million of trade receivables greater than 90 days past due as of January 1, 2022 and December 26, 2020, respectively. Advertising Costs The Company expenses advertising costs as incurred, which amounted to $2.1 million, $2.1 million, and $2.7 million in fiscal years 2021, 2020 and 2019, respectively, and are included as a component of selling, general, and administrative expenses. Shipping and Handling Fees and Costs 55 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS Amounts billed to customers related to shipping and handling are classified as revenue. Costs incurred for shipping and handling of $15.4 million, $11.1 million, and $11.0 million in fiscal years 2021, 2020, and 2019, respectively, are classified in selling, general, and administrative expenses. Foreign Currency Translation / Remeasurement The Company’s foreign subsidiaries use the local currency or the U.S. dollar as their functional currency, as appropriate. Assets and liabilities are translated using exchange rates at the balance sheet date, and revenues and expenses are translated at weighted average rates. Adjustments from the translation process are recognized in Shareholders’ equity as a component of Accumulated other comprehensive income (loss). The amount of foreign currency gain or loss from remeasurement recognized in the Consolidated Statements of Net Income was a loss of $17.2 million in fiscal year 2021, a gain of $14.9 million in fiscal year 2020, and a loss of $5.2 million in fiscal year 2019. Stock-Based Compensation The Company recognizes compensation expense for the cost of awards of equity compensation using a fair value method. Benefits of tax deductions in excess of recognized compensation expense are reported as operating cash flows. See Note 12, Stock-Based Compensation, for additional information on stock-based compensation. Coal Mining Liability Included in other long-term liabilities is an accrual related to former coal mining operations at Littelfuse GmbH (formerly known as Heinrich Industries, AG) for the amounts of €1.9 million ($2.1 million) and €2.3 million ($2.9 million) at January 1, 2022 and December 26, 2020, respectively. Management, in conjunction with an independent third-party, performs an annual evaluation of the former coal mining operations in order to develop an estimate of the probable future obligations in regard to remediating the dangers (such as a shaft collapse) of abandoned coal mine shafts in the former coal mining operations. Management accrues for costs associated with such remediation efforts based on management's best estimate when such costs are probable and reasonably able to be estimated. The ultimate determination can only be done after respective investigations because the concrete conditions are mostly unknown at this time. Other Expense (Income), Net Other expense (income), net generally consists of interest income, royalties, change in fair value of available-for-sale securities, pension non-service costs and settlements and other non-operating expense (income). Income Taxes The Company accounts for income taxes using the asset and liability method. Deferred taxes are recognized for the future effects of temporary differences between financial and income tax reporting using enacted tax rates in effect for the years in which the differences are expected to reverse. The Company recognizes deferred taxes for temporary differences, operating loss carryforwards, and tax credit and other tax attribute carryforwards (excluding carryforwards where usage has been determined to be remote). Deferred tax assets are reduced by a valuation allowance if it is more likely than not that some portion, or all, of the deferred tax assets will not be realized. U.S. state and non-U.S. income taxes are provided on the portion of non-U.S. income that is expected to be remitted to the U.S. and be taxable (and non-U.S. income taxes are provided on the portion of non-U.S. income that is expected to be remitted to an upper-tier non-U.S. entity). Deferred tax assets and liabilities are adjusted for the effects of changes in tax laws and rates on the date of enactment. Deferred U.S. income taxes and non-U.S. taxes are not provided on the excess of the investment value for financial reporting over the tax basis of investments in those non-U.S. subsidiaries for which such excess is considered to be permanently reinvested in those operations. Management regularly evaluates whether non-U.S. earnings are expected to be permanently reinvested. This evaluation requires judgment about the future operating and liquidity needs of the Company and its non-U.S. subsidiaries. Changes in economic and business conditions, tax laws, or the Company’s financial situation could result in changes to these judgments and the need to record additional tax liabilities. The Company recognizes the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the financial statements from such a position are measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement. 56 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS The 2017 Tax Cuts and Jobs Act (the "Tax Act"), among other things, imposed a one-time tax (the “Toll Charge”) on accumulated earnings of certain non-U.S. subsidiaries and included base broadening provisions commonly referred to as the global intangible low-taxed income provisions ("GILTI"). The Company elected to pay the 2017 Littelfuse Toll Charge over the eight-year period prescribed by the Tax Act. The long- term portion of this Toll Charge which remains payable as of January 1, 2022, totaling $17.8 million, is recorded in Other long- term liabilities, and the anticipated 2022 annual installment payment of $3.0 million is included in Accrued income taxes, on the Consolidated Balance Sheet as of January 1, 2022. In accordance with guidance issued by the FASB staff, the Company has adopted an accounting policy to treat any GILTI inclusions as a period cost if and when incurred. Thus, for the fiscal years ended January 1, 2022, December 26, 2020 and December 28, 2019, deferred taxes were computed without consideration of the possible future impact of the GILTI provisions, and any current year impact was recorded as a part of the current portion of income tax expense. Fair Value Measurements Certain assets and liabilities are required to be recorded at fair value on a recurring basis. Fair value is determined based on the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants. The Company records the fair value of its available-for-sale securities and pension plan assets on a recurring basis. Assets measured at fair value on a nonrecurring basis include long-lived assets held and used, long-lived assets held for sale, goodwill and other intangible assets. The fair value of cash and cash equivalents, accounts receivable, short-term debt and accounts payable approximate their carrying values. The three-tier value hierarchy, which prioritizes valuation methodologies based on the reliability of the inputs, is: Level 1 – Valuations based on quoted prices for identical assets and liabilities in active markets. Level 2 – Valuations based on observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets and liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data. Level 3 – Valuations based on unobservable inputs reflecting the Company’s own assumptions, consistent with reasonably available assumptions made by other market participants. Recently Adopted Accounting Standards In December 2019, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2019-12, "Income Taxes (Topic 740) - Simplifying the Accounting for Income Taxes" as part of its initiative to reduce complexity in the accounting standards. The guidance is effective for fiscal years beginning after December 15, 2020 with early adoption permitted. The adoption of ASU 2019-12 did not have a material impact on our Consolidated Financial Statements. Recently Issued Accounting Standards In October 2021, the FASB issued ASU No. 2021-08, "Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers". The standard requires an entity (acquirer) recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with Topic 606. The guidance is effective for fiscal years beginning after December 15, 2022 with early adoption permitted. The Company does not expect a material impact from the adoption of this guidance on the Company's Consolidated Financial Statements. In November 2021, the FASB issued ASU No. 2021-10, " Government Assistance (Topic 832): Disclosures by Business Entities about Government Assistance". The standard, requires annual disclosures about transactions with a government that are accounted for by applying a grant or contribution accounting model by analogy: 1) Information about the nature of the transactions and the related accounting policy used to account for the transactions; 2) The line items on the balance sheet and income statement that are affected by the transactions, and the amounts applicable to each financial statement line item; 3) Significant terms and conditions of the transactions, including commitments and contingencies. The guidance is effective for fiscal years beginning after December 15, 2021 with early adoption permitted. The Company does not expect a material impact from the adoption of this guidance on the Company's Consolidated Financial Statements. 57 2. Acquisitions NOTES TO CONSOLIDATED FINANCIAL STATEMENTS The Company accounts for acquisitions using the acquisition method in accordance with ASC 805, “Business Combinations,” in which assets acquired and liabilities assumed are recorded at fair value as of the date of acquisition. The operating results of the acquired business are included in the Company’s Consolidated Financial Statements from the date of the acquisition. Carling Technologies On November 30, 2021, the Company completed the previously announced acquisition of Carling Technologies, Inc. (“Carling”), pursuant to the Stock Purchase Agreement, dated as of October 19, 2021. Founded in 1920, Carling has a leading position in switching and circuit protection technologies with a strong global presence in commercial vehicle, marine and datacom/telecom infrastructure markets. At the time of acquisition, Carling had annualized sales of approximately $170 million. The business is headquartered in Plainville, Connecticut, with offices and facilities located around the world and is reported as part of the commercial vehicle business within our Transportation segment. The purchase price for Carling Technologies was approximately $315 million subject to change for a working capital adjustment. The acquisition was funded with cash on hand. The total purchase consideration of $313.6 million, net of cash, has been allocated, on a preliminary basis, to assets acquired and liabilities assumed, as of the completion of the acquisition, based on preliminary estimated fair values. The purchase consideration is subject to change for the final working capital adjustments. The purchase price allocation is preliminary because the evaluations necessary to assess the fair values of the net assets acquired are still in process. The primary areas that are not yet finalized relate to the completion of the valuations of certain property, plant and equipment, intangible assets and acquired income tax assets and liabilities. As a result, these allocations are subject to change during the purchase price allocation period as the valuations are finalized. The following table summarizes the preliminary purchase price allocation of the fair value of assets acquired and liabilities assumed in the Carling acquisition: (in thousands) Total purchase consideration: Cash, net of cash acquired Allocation of consideration to assets acquired and liabilities assumed: Trade receivables, net Inventories Other current assets Property, plant, and equipment Intangible assets Goodwill Other non-current assets Current liabilities Other non-current liabilities Purchase Price Allocation $ 313,583 25,503 57,450 3,454 64,301 125,890 92,366 4,104 (21,723) (37,762) $ 313,583 All Carling goodwill, other assets and liabilities were recorded in the Transportation segment and are primarily reflected in the Americas, Europe and Asia-Pacific geographic areas. The goodwill resulting from this acquisition consists largely of the Company’s expected future product sales and synergies from combining Carling’s products and technology with the Company’s existing commercial vehicle products portfolio. Goodwill resulting from the Carling acquisition is not expected to be deductible for tax purposes. Included in the Company’s Consolidated Statements of Net Income for the fiscal year ended January 1, 2022 are net sales of $15.3 million, and a loss before income taxes of $1.2 million, since the November 30, 2021 acquisition of Carling. As required by purchase accounting rules, the Company recorded a $6.4 million step-up of inventory to its fair value as of the acquisition date based on the preliminary valuation. The step-up is being amortized as a non-cash charge to cost of goods sold during the fourth quarter of 2021 and first quarter of 2022, as the acquired inventory is sold, and reflected as other non-segment 58 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS costs. The Company recognized a non-cash charge of $1.6 million to cost of goods sold during the fiscal year ended January 1, 2022. For the fiscal year ended January 1, 2022, the Company incurred approximately $4.5 million of legal and professional fees related to the Carling acquisition recognized as Selling, general, and administrative expenses. These costs were reflected as other non-segment costs. Hartland Controls On January 28, 2021, the Company acquired Hartland Controls ("Hartland"), a manufacturer and leading supplier of electrical components used primarily in heating, ventilation, air conditioning ("HVAC") and other industrial and control systems applications. At the time of acquisition, Hartland had annualized sales of approximately $70 million. The purchase price for Hartland was $111.0 million and the operations of Hartland are included in the Industrial segment. The total purchase consideration of $108.5 million, net of cash, cash equivalents, and restricted cash has been allocated to assets acquired and liabilities assumed, as of the completion of the acquisition, based on estimated fair values. As of January 1, 2022, the Company had restricted cash of $1.7 million in an escrow account for general indemnification purposes. The following table summarizes the final purchase price allocation of the fair value of assets acquired and liabilities assumed in the Hartland acquisition: (in thousands) Total purchase consideration: Cash, net of cash acquired, and restricted cash Allocation of consideration to assets acquired and liabilities assumed: Trade receivables, net Inventories Other current assets Property, plant, and equipment Intangible assets Goodwill Other non-current assets Current liabilities Other non-current liabilities Purchase Price Allocation $ 108,516 12,915 35,808 2,224 6,296 39,660 38,502 3,782 (24,861) (5,810) $ 108,516 All Hartland goodwill, other assets and liabilities were recorded in the Industrial segment and are primarily reflected in the Americas and Asia-Pacific geographic areas. The goodwill resulting from this acquisition consists largely of the Company’s expected future product sales and synergies from combining Hartland’s products and technology with the Company’s existing industrial products portfolio. Goodwill resulting from the Hartland acquisition is not expected to be deductible for tax purposes. Included in the Company’s Consolidated Statements of Net Income for the fiscal year ended January 1, 2022 are net sales of $100.5 million and a loss before income taxes of $2.8 million since the January 28, 2021 acquisition of Hartland. The Company recorded a $6.8 million step-up of inventory to its fair value as of the acquisition date based on the valuation. The step-up was fully amortized as a non-cash charge to cost of goods sold during the first and second quarters of 2021, as the acquired inventory was sold, and is reflected as other non-segment costs. For the fiscal year ended January 1, 2022, the Company recognized a charge of $6.8 million for the amortization of this fair value inventory step-up. For the fiscal year ended January 1, 2022, the Company incurred approximately $0.8 million of legal and professional fees related to the Hartland acquisition recognized as Selling, general, and administrative expenses. These costs were reflected as other non-segment costs.

The Company tests its goodwill annually for impairment on the first day of its fiscal fourth quarter, or more frequently if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying value. During the second quarter of 2020, the Company recorded a non-cash charge of $33.8 million to recognize the impairment of goodwill in the automotive sensors reporting unit within the Transportation segment. The goodwill impairment charge was due to reductions in the estimated fair value for the automotive sensors reporting unit based on lower expectations for future revenue, profitability and cash flows as compared to the expectations of the 2019 annual goodwill impairment test. These lower future expectations were driven by projected extended declines in end market demand due to the COVID-19 pandemic. In addition, during the second quarter of 2020, certain customers notified the Company of their decision to delay future programs along with a customer canceling their existing program. The goodwill impairment charge was determined using Level 3 inputs, including discounted cash flow analysis and comparable marketplace fair value data. As of January 1, 2022, the automotive sensors reporting unit had $9.2 million of remaining goodwill. The components of intangible assets at January 1, 2022 and December 26, 2020 are as follows: 61 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (in thousands) Land use rights Patents, licenses and software Distribution network Customer relationships, trademarks, and tradenames Total (in thousands) Land use rights Patents, licenses and software Distribution network Customer relationships, trademarks, and tradenames Total As of January 1, 2022 Gross Carrying Value Accumulated Amortization Net Book Value 19,542 $ 164,556 43,361 487,710 715,169 $ 1,906 $ 101,307 40,591 164,239 308,043 $ 17,636 63,249 2,770 323,471 407,126 As of December 26, 2020 Gross Carrying Value Accumulated Amortization Net Book Value 10,280 $ 137,210 43,910 372,064 563,464 $ 2,007 $ 92,868 38,980 137,722 271,577 $ 8,273 44,342 4,930 234,342 291,887 $ $ $ $ During the year ended January 1, 2022, the Company recorded additions to other intangible assets of $165.6 million, for acquisitions during 2021, the components of which were as follows: (in thousands, except weighted average useful life) Land use rights Patents, developed technology Customer relationships, trademarks, and tradenames Total Weighted Average Useful Life (Years) 50 9.8 13.0 2021 $ $ $ Amount 9,590 31,659 124,301 165,550 For intangible assets with definite lives, the Company recorded amortization expense of $42.7 million, $40.0 million, and $40.0 million in 2021, 2020, and 2019, respectively.

Bonus accruals include amounts earned pursuant to the Company’s primary employee incentive compensation plans. Other accrued liabilities include miscellaneous operating accruals and other client-related liabilities. 7. Lease Commitments Under ASC 842, a contract contains a lease if there is an identified asset and the Company has the right to control the asset. The Company determines whether a contract contains a lease at contract inception. The Company leases office and production space under various non-cancellable operating leases that expire no later than 2031. Certain real estate leases include one or more options to renew. The exercise of lease renewal options is at the Company's sole discretion. Options to extend the lease are included in the lease term when it is reasonably certain the Company will exercise the option. The Company also has production equipment, office equipment and vehicles under operating leases. The depreciable life of assets and leasehold improvements are limited by the expected lease term, unless there is a transfer of title or purchase option that is reasonably certain of exercise. Certain leases include rental payments adjusted periodically for inflation. The lease agreements do not contain any material residual value guarantee or material restrictive covenants. The Company has elected to use the available practical expedient to account for the lease and non-lease components of its leases as a single component. As the Company elected not to separate lease and non-lease components and instead to account for them as a single lease component, the variable lease cost primarily represents variable payments such as common area maintenance and utilities. The Company does not have a published credit rating because it has no publicly traded debt; therefore, the Company is generating its incremental borrowing rate ('IBR"), using a synthetic credit rating model that compares its credit quality to other rated companies based on certain financial metrics and ratios. The reference rate will be based on the yield curve of companies with similar credit quality based on the metrics and adjusted for currency in regions where we have significant operations. All leases with an initial term of 12 months or less that do not include an option to extend or purchase the underlying asset that the Company is reasonably certain to exercise (“short-term leases”) are not recorded on the Consolidated Balance Sheets. Short- term lease expenses are recognized on a straight-line basis over the lease term.

These charges primarily related to the reorganization of certain manufacturing, selling and administrative functions across all segments and the previously announced consolidation of a manufacturing facility within the Industrial segment. The Company also recognized $36.1 million of impairment charges, which included a $33.8 million goodwill impairment charge associated with the automotive sensors reporting unit within the Transportation segment in the second quarter of 2020 and a $2.2 million impairment charge related to the land and building associated with the Company’s previously announced consolidation of a manufacturing facility within the Industrial segment in the first quarter of 2020. See Note 5, Goodwill and Other Intangible Assets for further discussion regarding the goodwill impairment charge. 2019 For the year ended December 28, 2019, the Company recorded total restructuring charges of $12.7 million for employee termination costs and other restructuring charges. These charges primarily related to the reorganization of operations and selling, general and administrative functions as well as the integration of IXYS within the Electronics segment and the reorganization of operations in the automotive sensors and commercial vehicle products businesses within the Transportation segment. In April 2019, we announced the closure of a European manufacturing facility in the automotive sensors business within the Transportation segment. The Company recorded $1.7 million of employee termination costs and $1.4 million of other restructuring and impairment charges associated with this plant closure. The restructuring reserves as of January 1, 2022 and December 26, 2020 are $2.9 million and $4.2 million, respectively. The restructuring reserves are included within accrued liabilities.

Revolving Credit Facility On March 25, 2020, the company borrowed $100.0 million from its existing revolving credit facility to preserve financial flexibility and enhance liquidity, given the increasing levels of uncertainty related to COVID-19. The Company paid $5.0 million of principal payments on the term loan before the Company amended the credit agreement on April 3, 2020 as discussed below. On April 3, 2020, the Company amended its existing credit agreement to effect certain changes, including, among others: (i) eliminating the $200.0 million unsecured term loan credit facility, the remaining outstanding balance ($140.0 million) of which was repaid in full on April 3, 2020 through the revolving credit facility; (ii) making certain financial and non-financial covenants less restrictive on the Company; (iii) modifying performance-based interest rate margins and undrawn fees; and (iv) extending the maturity date to April 3, 2025. The amended credit agreement also allows the Company to increase the size of the revolving credit facility or enter into one or more tranches of term loans if there is no event of default and the Company is in compliance with certain financial covenants. The Company made payments of $30.0 million on the amended revolving credit facility during the fiscal year ended January 1, 2022. The balance under the facility was $100.0 million as of January 1, 2022. Outstanding borrowings under the amended credit agreement bear interest, at the Company’s option, at either LIBOR, fixed for interest periods of one, two, three or six-month periods, plus 1.25% to 2.00%, or at the bank’s Base Rate, as defined, plus 0.25% to 1.00%, based upon the Company’s Consolidated Leverage Ratio, as defined. The Company is also required to pay commitment fees on unused portions of the credit agreement ranging from 0.125% to 0.20%, based on the Consolidated Leverage Ratio, as defined in the agreement. The credit agreement includes representations, covenants and events of default that are customary for financing transactions of this nature. The effective interest rate on outstanding borrowings under the credit facility was 1.35% at January 1, 2022. As of January 1, 2022, the Company had no outstanding in letters of credit and had available $600.0 million of borrowing capacity under the revolving credit facility. At January 1, 2022, the Company was in compliance with all covenants under the credit agreement.

Fair Value of Assets and Liabilities NOTES TO CONSOLIDATED FINANCIAL STATEMENTS For assets and liabilities measured at fair value on a recurring and nonrecurring basis, a three-level hierarchy of measurements based upon observable and unobservable inputs is used to arrive at fair value. Observable inputs are developed based on market data obtained from independent sources, while unobservable inputs reflect the Company’s assumptions about valuation based on the best information available in the circumstances. Depending on the inputs, the Company classifies each fair value measurement as follows: Level 1—Valuations based on unadjusted quoted prices for identical assets or liabilities in active markets; Level 2—Valuations based upon quoted prices for similar instruments, prices for identical or similar instruments in markets that are not active, or model-derived valuations, all of whose significant inputs are observable, and Level 3—Valuations based upon one or more significant unobservable inputs. Following is a description of the valuation methodologies used for instruments measured at fair value and their classification in the valuation hierarchy. Cash Equivalents Cash equivalents primarily consist of money market funds, which are held with an institution with sound credit rating and are highly liquid. The Company classified cash equivalents as Level 1 and are valued at cost, which approximates fair value. Investments in Equity Securities Investments in equity securities listed on a national market or exchange are valued at the last sales price and classified within Level 1 of the valuation hierarchy. Such securities are further detailed in Note 1, Summary of Significant Accounting Policies and Other Information. Other Investments The Company has certain convertible debt and convertible preferred stock investments that are accounted for under the cost method reflected in Investments and Other assets in the Consolidated Balance Sheets. During the fiscal year ended January 1, 2022, the Company impaired the remaining book value of these investments and recorded an impairment charge of $0.5 million, and during the fiscal year ended December 26, 2020, the Company recorded $0.1 million in Other expense (income), net in the Consolidated Statements of Net Income. As o fJanuary 1, 2022 and December 26, 2020, the balances of these investments were zero and $0.5 million, respectively. The fair value of these investments are measured on a nonrecurring basis using Level 3 inputs under the fair value hierarchy. The Company's accounting and finance management determines the valuation policies and procedures for Level 3 fair value measurements and is responsible for the development and determination of unobservable inputs. Defined Benefit Plan Assets / Non-qualified Supplemental Retirement and Savings Plan Investments See Note 11, Benefit Plans, for description of valuation methodologies and investment balances for defined benefit plan assets and investments related to the Company’s Non-Qualified Supplemental Retirement and Savings Plan. Foreign currency exchange forward contract There were no changes during 2021 to the Company’s valuation techniques used to measure asset and liability fair values on a recurring basis. On October 30, 2019, the Company entered a foreign currency exchange forward contract to mitigate the currency fluctuation risk between the Chinese renminbi and U.S dollar. The foreign currency contract was not designated as a hedge instrument and was marked to market on a monthly basis. The notional value of the forward contracts at December 28, 2019 was $16.0 million and expired on May 5, 2020. On March 23, 2020, the Company unwound the foreign currency exchange forward contract entered on October 30, 2019 and recognized a gain of $0.2 million within Other expense (income), net during the fiscal year 2020. The fair value of the foreign currency forward contract was valued using market exchange rates and classified as a Level 2 input under the fair value hierarchy. As of January 1, 2022 and December 26, 2020, the Company held no non-financial assets or liabilities that are required to be measured at fair value on a recurring basis. 68 The following table presents assets measured at fair value by classification within the fair value hierarchy as of January 1, 2022: NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (in thousands) Cash Equivalents Investments in equity securities Mutual funds Total: Fair Value Measurements Using Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) $ $ 12,475 $ — $ — $ 26,070 15,021 — — — — 53,566 $ — $ — $ Total 12,475 26,070 15,021 53,566 The following table presents assets measured at fair value by classification within the fair value hierarchy as of December 26, 2020: (in thousands) Cash Equivalents Investments in equity securities Mutual funds Total: Fair Value Measurements Using Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) $ $ 73,461 $ 19,186 13,249 105,896 $ — $ — — — $ — $ — — — $ Total 73,461 19,186 13,249 105,896 In addition to the methods and assumptions used for the financial instruments recorded at fair value as discussed above, the following methods and assumptions are used to estimate the fair value of other financial instruments that are not marked to market on a recurring basis. The Company’s other financial instruments include cash and cash equivalents, short-term investments, trade receivables and its long-term debt. Due to their short-term maturity, the carrying amounts of cash and cash equivalents, short-term investments and trade receivables approximate their fair values. The Company’s revolving and term loan debt facilities’ fair values approximate book value at January 1, 2022 and December 26, 2020, as the rates on these borrowings are variable in nature.

Benefit Plans The Company has Company-sponsored and mandatory defined benefit pension plans covering employees in the United Kingdom ("U.K."), Germany, the Philippines, China, Japan, Mexico, Italy and France. The amount of the retirement benefits provided under the plans is generally based on years of service and final average pay. On April 7, 2020, the Company entered into a definitive agreement to purchase a group annuity contract, under which an insurance company is required to directly pay and administer pension payments to certain of the Company’s U.K. pension plan participants, or their designated beneficiaries. Due to the signing of the group annuity contract being a significant change in one of the U.K. pension plans, the liabilities of the plan were remeasured as of April 6, 2020 resulting in an increase of $13.4 million (£10.9 million) to both the net pension liability to bring the pension benefit obligation to the purchase price of the group annuity contract, and unamortized actuarial loss within other comprehensive income (loss) during the second quarter of 2020. Additionally, the Company made a cash contribution of $10.4 million (£8.4 million) under this agreement during the second quarter of 2020. The Company completed the buy-out of this U.K. pension plan during the fourth quarter of 2021 and as a result recorded a non-cash pension settlement charge of $19.9 million (£14.9 million), inclusive of the accelerated recognition of prior service cost of $0.5 million (£0.4 million). The purchase of this group annuity contract reduced the Company’s outstanding pension benefit obligation by $47.1 million, representing 35% of the total obligations of the Company’s qualified pension plans.

The Company also sponsors certain post-employment plans in foreign countries and other statutory benefit plans. For the fiscal year ended January 1, 2022, December 26, 2020, and December 28, 2019, the Company recorded $2.1 million, $2.0 million, $1.4 million expense, respectively, in Cost of Sales and Other expense (income), net within the Consolidated Statements of Net Income. As of January 1, 2022 and December 26, 2020, the Company reported benefit liabilities of $4.1 million and $3.5 million for these plans, of which $1.5 million and $1.2 million was recorded in Accrued liabilities and $2.6 million and $2.3 million was recorded in Other long-term liabilities on the Consolidated Balance Sheets, respectively. For the fiscal year ended January 1, 2022 and December 26, 2020, the pre-tax amounts recognized in other comprehensive income (loss) for these plans 72 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS were $0.3 million and $0.1 million, respectively. For the fiscal year ended January 1, 2022 and December 26, 2020, the amount reclassified from accumulated other comprehensive income (loss) were $0.7 million and $0.7 million, respectively. Defined Benefit Plan Assets Based upon analysis of the target asset allocation and historical returns by type of investment, the Company has assumed that the expected long-term rate of return will be 1.4% on plan assets. Assets are invested to maximize long-term return taking into consideration timing of settlement of the retirement liabilities and liquidity needs for benefits payments. Pension plan assets were invested as follows, and were not materially different from the target asset allocation: Cash and cash equivalents, and other Equity securities Fixed income securities Bulk annuity contract Asset Allocation 2021 2020 15 % 19 % 66 % — % 100 % 7 % 9 % 31 % 53 % 100 % The Company segregated its plan assets by the following major categories and level for determining their fair value as of January 1, 2022 and December 26, 2020. All plan assets that are valued using the net asset value per share (“NAV”) practical expedient have not been included within the fair value hierarchy but are separately disclosed. Cash and cash equivalents – Carrying value approximates fair value. As such, these assets were classified as Level 1. The Company also invests in certain short-term investments which are valued using the amortized cost method. Lastly, the Company has certain pooled pension funds that have short-term investments with third party mutual funds that are valued at unit value per share at measurement date. As such, these assets were classified as Level 2. Equity – The values of individual equity securities were based on quoted prices in active markets. As such, these assets are classified as Level 1. The Company has certain pooled pension funds which have mutual funds with underlying investments in certain equity securities that are not quoted on active markets; therefore, they were classified as Level 2. Fixed income – Fixed income securities are typically priced based on a last trade basis and are exchange-traded. Accordingly, the Company classified fixed income securities as Level 1. The Company has certain pooled pension funds which have mutual funds with underlying investments in fixed income securities and funds priced based on a valuation model rather than a last trade basis and are not exchange-traded. As such, they were classified as Level 2. The Company also invests in certain fixed income funds which are valued at NAV. Insurance Contracts and other – This category includes pooled pension funds which have mutual funds with underlying investments in other assets and liabilities including alternatives priced based on a valuation model and are not exchange-traded. These were classified as Level 2. This category includes also insurance contracts that are valued by the re-insurer with the valuation inputs being not highly observable or traded on an open market. Accordingly, insurance contracts were categorized as Level 3. Lastly, this category includes other assets and liabilities including futures or swaps. Bulk Annuity Contract – Bulk annuity contract includes a U.K insurance policy issued by an authorized U.K. life insurer. This bulk annuity contract is valued by the re-insurer with the valuation inputs being not highly observable or traded on an open market. Accordingly, this contract was categorized as Level 3. The Company has no bulk annuity contract pension assets as of January 1, 2022. For any Level 2 and Level 3 plan assets, management reviews significant investments on a periodic basis including investigation of unusual fluctuations in price or returns and obtaining an understanding of the pricing methodology to assess the reliability of third-party pricing estimates. The valuation methodologies described above may generate a fair value calculation that may not be indicative of net realizable value or future fair values. While the Company believes the valuation methodologies used are appropriate, the use of different methodologies or assumptions in calculating fair value could result in different amounts. The Company invests in assets in which valuation is determined by NAV. The Company believes that the NAV is representative of fair value at the reporting 73 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS date, as there are no significant restrictions on redemption of these investments or other reasons to indicate that the investment would be redeemed at an amount different than the NAV.

The Company matches 100% of the employee’s annual contributions for the first 4% of the employee’s eligible compensation. The Company may provide an additional discretionary match to participants and made discretionary matches of 2% of the employee’s eligible compensation for each of the fiscal year ended January 1, 2022, December 26, 2020 and December 28, 2019. Employees are immediately vested in their contributions plus actual earnings thereon, as well as the Company contributions. Company matching contributions amounted to $5.0 million, $4.6 million, and $5.6 million in 2021, 2020, and 2019, respectively. Non-qualified Supplemental Retirement and Savings Plan The Company has a non-qualified Supplemental Retirement and Savings Plan which provides additional retirement benefits for certain management employees and named executive officers by allowing participants to defer a portion of their annual compensation. The Company maintains accounts for participants through which participants make investment elections. The investments are subject to the claims of the Company’s creditors and the Company is responsible for the payment of all benefits 74 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS under the plan from its general assets. As of January 1, 2022, there was $15.0 million of marketable securities related to the plan included in Other assets and $15.0 million of accrued compensation benefits included in Other long-term liabilities. The marketable securities are classified as Level 1 under the fair value hierarchy as they are maintained in mutual funds with readily determinable fair value. The Company made matching contributions to the plan of $0.2 million, $0.5 million, and $0.4 million in 2021, 2020, and 2019, respectively. 12. Stock-Based Compensation Equity Plans: The Company has equity-based compensation plans authorizing the granting of stock options, restricted shares, restricted share units, and other stock rights to employees and directors. As of January 1, 2022, there were 0.8 million shares available for issuance of future awards under the Company’s equity-based compensation plans. Stock options generally vest over a three-year period and are exercisable over either a seven or ten-year period commencing from the date of the grant. Restricted shares and share units granted by the Company generally vest over three years. Stock options and restricted share units may have accelerated vesting upon meeting certain qualified conditions. The following table provides a reconciliation of outstanding stock options for the fiscal year ended January 1, 2022. Outstanding December 26, 2020 Granted Exercised Forfeited Outstanding January 1, 2022 Exercisable January 1, 2022 Shares Under Option Weighted Average Price 666,949 $ 57,928 (151,015) (10,636) 563,226 240,030 148.01 267.66 126.61 151.93 165.98 148.66 Weighted Average Remaining Contract Life (Years) Aggregate Intrinsic Value (000’s) 4.7 $ 3.7 83,749 39,850 The following table provides a reconciliation of non-vested restricted share and share unit awards ("RSU") for the fiscal year ended January 1, 2022. Nonvested December 26, 2020 Granted Vested Forfeited Nonvested January 1, 2022 Weighted Average Grant-Date Fair Value Shares 172,002 $ 63,237 (72,904) (5,676) 156,659 152.25 264.69 162.59 162.85 192.44 The total intrinsic value of options exercised during 2021, 2020, and 2019 was $23.8 million, $20.6 million, and $12.5 million, respectively. The total fair value of the vested RSU shares was $18.9 million, $9.5 million, and $15.5 million for 2021, 2020, and 2019, respectively. The total amount of share-based liabilities paid was $1.3 million, $0.5 million and $0.9 million for 2021, 2020, and 2019, respectively. The Company recognizes compensation cost of all share-based awards as an expense on a straight-line basis over the vesting period of the awards. At January 1, 2022, the unrecognized compensation cost for options and restricted shares was $21.9 million before tax, and will be recognized over a weighted average period of 1.8 years. Compensation cost included as a component of cost of sales, research and development and selling, general, and administrative expenses for all equity compensation plans discussed above was $21.4 million, $19.1 million, and $19.9 million for 2021, 2020, and 2019, respectively. The total related income tax benefit recognized in the Consolidated Statements of Net Income was $3.3 million, $3.1 million and $3.3 million for 2021, 2020, and 2019, respectively. 75 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS The Company uses the Black-Scholes option valuation model to determine the fair value of stock option awards granted. The weighted average fair value of and related assumptions for options granted are as follows: Weighted average fair value of options granted Assumptions: Risk-free interest rate Expected dividend yield Expected stock price volatility Expected life of options (years) 2021 $74.04 0.66% 0.72% 35.0% 4.4 2020 $38.09 0.30% 1.27% 33.0% 4.7 2019 $47.63 2.33% 0.86% 27.0% 4.4 Expected volatilities are based on the historical volatility of the Company’s stock price. The expected life of options is based on historical data for options granted by the Company. The risk-free rates are based on yields available at the time of grant on U.S. Treasury bonds with maturities consistent with the expected life assumption. Historical nonvested forfeiture information is the basis for the forfeiture rate assumptions. The fair value of RSU is determined based on the Company's stock price on the grant date reduced by the present value of expected dividends through the vesting period. Preferred Stock: The Board of Directors may authorize the issuance of preferred stock from time to time in one or more series with such designations, preferences, qualifications, limitations, restrictions, and optional or other special rights as the Board may fix by resolution. Share Repurchase Program On April 26, 2019, the Company's Board of Directors authorized a program to repurchase up to 1,000,000 shares of the Company's common stock for the period May 1, 2019 to April 30, 2020 ("2019 program"). On April 29, 2020, the Company announced that the Board of Directors authorized a new program to repurchase up to 1,000,000 shares of the Company's common stock for the period May 1, 2020 to April 30, 2021 (the "2020 program") to replace its previous expired 2019 program. On April 28, 2021, the Company announced that the Board of Directors authorized a new three-year program to repurchase up to $300 million in the aggregate of shares of the Company’s common stock for the period May 1, 2021 to April 30, 2024 to replace its previous 2020 program. There are $300 million in the aggregate of shares available for purchase under the new program as of January 1, 2022. During the fiscal year 2021, the Company did not repurchase any shares of its common stock. During the fiscal year 2020 and 2019, the Company repurchased 175,110 and 579,916 shares of its common stock totaling $22.9 million and $95.0 million, respectively. 76 13.

Income Taxes NOTES TO CONSOLIDATED FINANCIAL STATEMENTS The 2017 Tax Cuts and Jobs Act (the "Tax Act"), among other things, imposed a one-time tax (the “Toll Charge”) on accumulated earnings of certain non-U.S. subsidiaries and included base broadening provisions commonly referred to as the global intangible low-taxed income provisions ("GILTI"). The Company elected to pay the 2017 Littelfuse Toll Charge over the eight-year period prescribed by the Tax Act. The long- term portion of this Toll Charge which remains payable as of January 1, 2022, totaling $17.8 million, is recorded in Other long- term liabilities, and the anticipated 2022 annual installment payment of $3.0 million is included in Accrued income taxes, on the Consolidated Balance Sheet as of January 1, 2022. In accordance with guidance issued by the FASB staff, the Company has adopted an accounting policy to treat any GILTI inclusions as a period cost if and when incurred. Thus, for the fiscal years ended January 1, 2022, December 26, 2020 and December 28, 2019, deferred taxes were computed without consideration of the possible future impact of the GILTI provisions, and any current year impact was recorded as a part of the current portion of income tax expense. Domestic and foreign income (loss) before income taxes is as follows: (in thousands) Domestic Foreign Income before income taxes 2021 2020 2019 $ $ 13,746 $ 327,279 341,025 $ (16,732) $ 177,985 161,253 $ (11,970) 177,854 165,884 Federal, state and foreign income tax expense (benefit) consists of the following: (in thousands) Current: Federal State Foreign Subtotal Deferred: Federal and State Foreign Subtotal Provision for income taxes 2021 2020 2019 $ $ 4,832 $ 1,401 59,006 65,239 (9,658) 1,638 (8,020) 57,219 $ 437 $ 203 33,841 34,481 (5,354) 2,140 (3,214) 31,267 $ (3,495) 834 30,610 27,949 1,839 (2,986) (1,147) 26,802 The current federal tax benefit for 2019 includes a benefit of $3.3 million from the recognition of previously unrecognized tax benefits (and the reversal of the related accrued interest) due to a lapse in the statute of limitations.

Significant components of the company’s deferred tax assets and liabilities at January 1, 2022 and December 26, 2020, are as follows: (in thousands) Deferred tax assets: Accrued expenses and reserves Domestic and non-U.S. net operating loss carryforwards Domestic and non-U.S. interest expense carryforwards Excess of tax basis over the book basis for intangible assets and goodwill Capitalized expenses U.S. research and other general business tax credit carryforwards U.S. foreign tax credit carryforwards Other Gross deferred tax assets Less: Valuation allowance Total deferred tax assets Deferred tax liabilities: Excess of book basis over the tax basis for intangible assets and goodwill Tax on unremitted earnings Unrealized foreign currency exchange gains Excess of book basis over the tax basis for property, plant, and equipment Total deferred tax liabilities Net deferred tax liabilities 2021 2020 36,168 $ 27,818 16,089 5,636 4,878 1,104 980 183 92,856 (34,869) 57,987 31,123 24,763 10,352 — 4,178 3,724 772 117 75,029 (13,131) 61,898 98,046 15,467 73 12,563 126,149 68,162 $ 76,472 14,223 5,719 4,394 100,808 38,910 $ $ The deferred tax asset valuation allowance is mainly related to certain U.S. and non-U.S. net operating loss and non-U.S. interest expense carryforwards which are not expected to be realized. The remaining U.S. and non-U.S. net operating loss and interest expense carryforwards either have no expiration date or are expected to be utilized prior to expiration. No deferred tax asset nor valuation allowance has been recorded for certain U.S. and non-U.S. net operating loss carryforwards for which the possibility of usage has been determined to be remote. The Company paid income taxes of $58.2 million, $35.2 million, and $47.6 million in 2021, 2020, and 2019, respectively, and received income tax refunds of $2.6 million, $7.6 million, and $7.1 million in 2021, 2020, and 2019, respectively. Deferred income taxes are not provided on the excess of the investment value for financial reporting over the tax basis of investments in those non-U.S. subsidiaries for which such excess is considered to be permanently reinvested in those operations. The Company believes the determination of the amount of such deferred income taxes is impractical as it would depend upon income tax laws and circumstances at the time of the hypothetical distributions or dispositions. As of January 1, 79 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 2022, unremitted earnings of the Company’s non-U.S. subsidiaries were approximately $884 million. A distribution of such earnings will generally not be subject to U.S. federal income tax. The Company recognized deferred tax liabilities of $15.5 million ($15.3 million for non-U.S. taxes net of related U.S. foreign tax credits, and $0.2 million for U.S. state taxes) as of January 1, 2022 and $14.2 million ($13.9 million for non-U.S. taxes net of related U.S. foreign tax credits, and $0.3 million for U.S. state taxes) as of December 26, 2020, related to taxes on certain non-U.S. earnings which are not considered to be permanently reinvested. The Company has two subsidiaries in China which benefit from lower tax rates due to “tax holidays” which apply for three-year periods. The tax holiday for one of the subsidiaries expires at the end of 2022, and for the other subsidiary the tax holiday will expire at the end of 2023. Together, the tax holidays contributed $7.8 million in tax benefits, or $0.31 per diluted share, during 2021. Future year tax benefits will depend upon the Company’s ability to obtain extensions, after the three-year periods expire. There can be no assurance that future extensions will be granted. A reconciliation of the beginning and ending amount of unrecognized tax benefits as of January 1, 2022, December 26, 2020, and December 28, 2019 is as follows: (in thousands) Balance at December 28, 2019 Additions for tax positions taken in the current year Decreases due to a lapse in the statute of limitations Other Balance at December 26, 2020 Additions for tax positions related to pre-acquisition periods of acquired subsidiaries Additions for tax positions taken in the current year Additions for tax positions taken in the prior year Other Balance at January 1, 2022 Unrecognized Tax Benefits 16,721 $ 700 (103) 119 17,437 3,260 1,587 1,100 61 23,445 The January 1, 2022 total in the table above represents the net amount of tax benefits that, if recognized, would favorably affect the effective tax rate in future periods. Of this amount, only an insignificant amount may be recognized in 2022 based upon the possible lapse in the statute of limitations. None of the positions included in unrecognized tax benefits are related to tax positions for which the ultimate deductibility is highly certain, but for which there is uncertainty about the timing of such deductibility. The company recognizes accrued interest and penalties associated with uncertain tax positions as part of income tax expense. The company recognized such interest expense of $1.6 million, $1.6 million (net of a $0.6 million decrease due to a lapse in the statute of limitations), and $1.3 million (net of a $0.6 million decrease due to a lapse in the statute of limitations) in 2021, 2020, and 2019, respectively. Accrued interest for such matters included in Other long-term liabilities within the Consolidated Balance Sheets was $10.4 million and $8.8 million as of January 1, 2022 and December 26, 2020, respectively. The U.S. federal statute of limitations remains open for the Company for the 2017 tax year (with respect to the Toll Charge) and later years. Non-U.S. and U.S. state statutes of limitations generally range from three to seven years, although certain jurisdictions do not have a statute expiration. Tax examinations occur from time to time, including examinations currently in process in Korea, the Netherlands, the Philippines, and certain U.S. states. The company does not expect to recognize a significant amount of additional tax expense as a result of concluding these examinations. During 2021, the Company received a notice of assessment for approximately $3 million from the Canadian tax authorities. The Company has objected to and appealed the assessment, and does not expect to recognize a significant amount of additional tax expense upon conclusion of such appeal. 80 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 15.

During the fiscal year 2021, the Company did not repurchase any shares of its common stock. During the fiscal year 2020 and 2019, the Company repurchased 175,110, and 579,916 shares of its common stock totaling $22.9 million and $95.0 million, respectively. See Note 12 Stock-Based Compensation for further discussion. 16. Segment Information The Company and its subsidiaries design, manufacture and sell component, modules and subassemblies to empower the long- term structural themes of sustainability, connectivity and safety. The Company reports its operations by the following segments: Electronics, Transportation, and Industrial. An operating segment is defined as a component of an enterprise that engages in business activities from which it may earn revenues and incur expenses, and about which separate financial information is regularly evaluated by the Chief Operating Decision Maker (“CODM”) in deciding how to allocate resources. The CODM is the Company’s President and Chief Executive Officer (“CEO”). The CODM allocates resources to and assesses the performance of each operating segment using information about its revenue and operating income (loss) before interest and taxes, but does not evaluate the operating segments using discrete balance sheet information. Sales, marketing, and research and development expenses are charged directly into each operating segment. Purchasing, logistics, customer service, finance, information technology, and human resources are shared functions that are allocated back to the three operating segments. The Company does not report inter-segment revenue because the operating segments do not record it. Certain expenses, determined by the CODM to be strategic in nature and not directly related to segments current results, are not allocated but identified as “Other”. Additionally, the Company does not allocate interest and other income, interest expense, or taxes to operating segments. These costs are not allocated to the segments, as management excludes such costs when assessing the performance of the segments. Although the CODM uses operating income (loss) to evaluate the segments, operating costs included in one segment may benefit other segments. Except as discussed above, the accounting policies for segment reporting are the same as for the Company as a whole. • Electronics Segment: Consists of one of the broadest product offerings in the industry, including fuses and fuse accessories, positive temperature coefficient (“PTC”) resettable fuses, polymer electrostatic discharge (“ESD”) suppressors, varistors, reed switch based magnetic sensing, gas discharge tubes; semiconductor products such as discrete transient voltage suppressor (“TVS”) diodes, TVS diode arrays, protection and switching thyristors, silicon and silicon carbide metal-oxide-semiconductor field effect transistors (“MOSFETs”) and diodes; and insulated gate bipolar transistors (“IGBT”) technologies. The segment covers a broad range of end markets, including industrial motor drives and power conversion, automotive electronics, electric vehicle and related infrastructure, power supplies, data centers and telecommunications, medical devices, alternative energy and energy storage, building and home automation, appliances, and mobile electronics. 81 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS • • Transportation Segment: Formerly known as Automotive segment. The term “Transportation” represents a more comprehensive description of the Company’s broad range of products, and the applications and end markets it serves. Consists of a wide range of circuit protection, power control and sensing technologies for global original equipment manufacturers (“OEMs”), Tier-one suppliers and parts and aftermarket distributors in passenger vehicle, heavy duty truck, off-road vehicles, material handling, agricultural, construction and other commercial vehicle end markets. Passenger vehicle products are used in internal combustion engine, hybrid and electric vehicles including blade fuses, battery cable protectors, resettable fuses, high-current fuses, high-voltage fuses, and sensor products designed to monitor the occupant’s safety and environment as well as the vehicle’s powertrain. Commercial vehicle products include fuses, switches, circuit breakers, relays, and power distribution modules and units used in applications serving a number of end markets, including heavy-duty truck, construction, agriculture, material handling and marine. Industrial Segment: Consists of industrial circuit protection (industrial fuse), industrial controls (protection relay, contactors, transformers) and temperature sensors for use in various applications such as renewable energy and energy storage systems, electric vehicle infrastructure, HVAC systems, industrial safety, non-residential construction, MRO, mining and industrial automation.

Evaluation of Disclosure Controls and Procedures The Company maintains disclosure controls and procedures that are designed to ensure that information required to be disclosed in its reports filed under the Securities Exchange Act of 1934, as amended, is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and that such information is accumulated and communicated to management, including the Company’s Chief Executive Officer and Chief Financial Officer, as appropriate, to allow for timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, the Company recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and the Company is required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures. As required by SEC Rule 15d-15(b), the Company carried out an evaluation, under the supervision and with the participation of its management, including the Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of its disclosure controls and procedures pursuant to SEC Rule 13a-15 as of the end of the period covered by this report. Based on the foregoing, the Company’s Chief Executive Officer and Chief Financial Officer concluded that the Company’s disclosure controls and procedures were effective as of January 1, 2022. Management’s Report on Internal Control over Financial Reporting Section 404 of the Sarbanes-Oxley Act of 2002 requires management to include in this Annual Report on Form 10-K a report on management’s assessment of the effectiveness of the Company’s internal control over financial reporting, as well as an attestation report from the Company’s independent registered public accounting firm on the effectiveness of the Company’s internal control over financial reporting. Management is responsible for establishing and maintaining adequate internal control over financial reporting as such term is defined in Exchange Act Rule 13a-15(f) and 15d-15(f). The Company’s internal control system was designed to provide reasonable assurance to its management and the Board of Directors regarding the preparation and fair presentation of published financial statements. 85 All internal control systems, no matter how well designed, have inherent limitations. Therefore, even those systems determined effective can provide only reasonable assurance with respect to financial statement preparation and presentation. A material weakness is a deficiency, or a combination of deficiencies, in the internal control over financial reporting such that there is a reasonable possibility that a material misstatement of the annual or interim financial statement will not be prevented or detected on a timely basis. The Company’s management, including its Principal Executive Officer and Principal Financial Officer, assessed the effectiveness of the Company’s internal control over financial reporting as of January 1, 2022, based upon the updated framework in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”) in 1992 and updated in May 2013. Based on this assessment, the Company’s management concluded that, as of January 1, 2022, the Company’s internal control over financial reporting was effective. On November 30, 2021, the Company completed the acquisition of Carling Technologies, as discussed in Note 2 – Acquisitions. Management has excluded Carling’s internal controls over financial reporting from its assessment of the effectiveness of internal controls over financial reporting as of January 1, 2022. Carling’s net sales and total assets (excluding goodwill and intangible assets, which were integrated into the Company’s control environment) represent approximately 1% and 5%, respectively, of the consolidated financial statement amounts as of, and for the fiscal year ended, January 1, 2022. Changes in Internal Control over Financial Reporting There has been no change in the Company’s internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that occurred during the 12 months or fiscal quarter ended January 1, 2022, that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting.

COMPENSATION PLAN INFORMATION We have two equity compensation plans that have been approved by our stockholders: the Littelfuse, Inc. Long-Term Incentive Plan that was approved by our stockholders at the April 2017 annual stockholder meeting and the Deferred Compensation Plan for Non-Employee Directors that was approved by our stockholders at the May 2005 annual stockholder meeting. Pursuant to our acquisition of IXYS Corporation on January 17, 2018, we assumed four equity compensation plans that have not been approved by our stockholders and pursuant to which we may continue to grant equity awards: IXYS Corporation 2009 Equity Incentive Plan, IXYS Corporation 2011 Equity Incentive Plan, IXYS Corporation 2013 Equity Incentive Plan, IXYS Corporation 2016 Equity Incentive Plan (together, the "IXYS Plans"). We also assumed two expired equity compensation plans that have not been approved by our stockholders and pursuant to which we have outstanding equity awards: the Zilog, Inc. 2002 Omnibus Stock Incentive Plan and Zilog, Inc. 2004 Omnibus Stock Incentive Plan (together the "Zilog Plans"). The IXYS Corporation 2009 Equity Incentive Plan expired in June 2019 and equity awards remain outstanding under it. 87 Information about our equity compensation plans that were either approved or not approved by our stockholders as of January 1, 2022, is as follows: Number of securities to be issued upon exercise of outstanding options, warrants and rights Weighted-average exercise price of outstanding options, warrants, and rights (1) Number of securities remaining available for future issuance under equity compensation plans (excluding securities reflected in the first column) 650,680 (2) 80,115 (3) 730,795 $131.47 $99.14 $127.92 598,766 (4) 193,848 (5) 792,614 Plan Category Equity compensation plans approved by security holders Equity compensation plans not approved by security holders Total (1) The weighted average exercise price does not take into account the shares issuable upon the vesting of outstanding restricted stock units, which have no exercise price. (2) Includes 161,815 shares reserved for issuance upon vesting of outstanding restricted stock units and 488,865 outstanding stock options granted under the Littelfuse, Inc. Long-Term Incentive Plan. (3) Includes 5,754 shares reserved for issuance upon vesting of outstanding restricted stock units under the IXYS Plans and 74,361 outstanding stock options granted under the IXYS Plans and Zilog Plan. Below is a brief description of the material features of the compensation plans acquired pursuant to the acquisition of IXYS Corporation. (4) Includes 554,119 shares that remain available for future issuance under the Littelfuse, Inc. Long-Term Incentive Plan and 44,647 shares that remain available for future issuance under the Deferred Compensation Plan for Non-Employee Directors. (5) Includes 24,926 shares that remain available for future issuance under the IXYS Corporation 2013 Equity Incentive Plan, and 168,922 shares that remain available for future issuance under the IXYS Corporation 2016 Equity Incentive Plan. IXYS Plans In connection with the acquisition of IXYS Corporation, we assumed the IXYS Corporation 2009 Equity Incentive Plan, IXYS Corporation 2011 Equity Incentive Plan, IXYS Corporation 2013 Equity Incentive Plan, IXYS Corporation 2016 Equity Incentive Plan and outstanding unvested stock options originally granted by IXYS Corporation under the IXYS Plans that were held by continuing employees. At the time of the acquisition of IXYS Corporation, these awards were converted to Littelfuse stock options, with adjustments made to the exercise price of the stock options and the number of shares subject to stock options as agreed upon in the Acquisition Agreement. These unvested options vest in accordance with their original terms, generally vesting in equal annual installments over a four-year period from the original grant date. The options, once granted, generally expire ten years from the date of grant. Under the IXYS Plans, we may grant to former employees of IXYS Corporation or its subsidiaries restricted stock awards, RSUs, stock options and stock appreciation rights with an exercise price that is no less than the fair market value on the date of grant. Equity awards granted under the IXYS Plans following the acquisition have been on similar terms and consistent with grants made pursuant to the Littelfuse, Inc Long-Term Incentive Plan. The IXYS Corporation 2009 and 2011 Equity Incentive Plans expired in June 2019 and June 2021 respectively, with no additional grants made after the expiration date. As of January 1, 2022, 193,848 shares remained available for issuance under the IXYS Plans. Zilog Plan In connection with the acquisition of IXYS Corporation, we assumed the Zilog, Inc. 2004 Omnibus Stock Incentive Plan and outstanding stock options originally granted by IXYS Corporation under the Zilog Plan that were held by continuing employees of Zilog. At the time of the acquisition of IXYS Corporation, these awards were converted to Littelfuse stock options, with adjustments made to the exercise price of the stock options and the number of shares subject to stock options as agreed upon in the Acquisition Agreement. These options vested in accordance with their original terms, generally in equal annual installments over a four-year period from the original grant date. The options generally expire ten years from the date of grant. The Zilog 2004 Omnibus Stock Incentive Plan expired in February 2014 and no additional grants have been made thereunder. Therefore, 88 as of January 1, 2022, no shares remain available for issuance of new awards under the Zilog Plan and 12,486 stock options remain outstanding. ITEM 12.
