GENERAL PART I Littelfuse, Inc., was incorporated under the laws of the State of Delaware in 1991. References herein to the ‘‘Company,’’ ‘‘we,’’ ‘‘our’’ or ‘‘Littelfuse’’ refer to Littelfuse, Inc. and its subsidiaries. References herein to ‘‘2023’’, ‘‘fiscal 2023’’ or ‘‘fiscal year 2023’’ refer to the fiscal year ended December 30, 2023. References herein to ‘‘2022’’, ‘‘fiscal 2022’’ or ‘‘fiscal year 2022’’ refer to the fiscal year ended December 31, 2022. References herein to ‘‘2021’’, ‘‘fiscal 2021’’ or ‘‘fiscal year 2021’’ refer to the fiscal year ended January 1, 2022. 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 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 2022 and fiscal 2023 contained 52 weeks. OVERVIEW Founded in 1927, Littelfuse is a diversified, industrial technology manufacturing company empowering a sustainable, connected, and safer world. Across more than 20 countries, and with approximately 17,000 global associates, we partner with customers to design and deliver innovative, reliable solutions. Serving over 100,000 end customers, our products are found in a variety of industrial, transportation and electronics end markets – everywhere, every day. Segments The Company conducts its business through three reportable segments: Electronics, Transportation, and Industrial. Within these segments, the Company designs, manufactures and sells electronic components, modules and subassemblies to empower the long-term secular growth themes of sustainability, connectivity and safety. Over the last decade the Company has positioned itself within the center of these global structural growth themes by helping to enable its customers’ applications focused on a more sustainable, connected, and safer world. The ever-increasing complexity of applications surrounding these themes continues to drive greater demand for the Company’s innovative, reliable products and a higher level of product content within a broad range of applications. With its expanding, diversified, product portfolio, the Company has evolved its presence across the industrial, transportation and electronics end markets it serves. The Company’s exposure with each of these end markets is relatively balanced. With a deep list of target applications within each primary end market, the Company believes its balanced approach positions its business for the long-term sustainability, increases diversification and creates additional growth opportunities. Across electronics end markets, product demand is largely driven by electrification, energy and power efficiency, automation, connectivity, artificial intelligence, and safety. In transportation end markets, including passenger and commercial vehicles, the ongoing electronification and electrification of applications is driving increased product demand. Across industrial end markets, product demand is driven by an ecosystem that continues to advance sustainability, safety and automation capabilities. For example, renewables, including solar and wind energy, and energy storage systems that enable lower carbon emissions, the ongoing proliferation of electric vehicles and charging stations, more efficient climate control units, increasing requirements for electrical safety, the rising demand for factory and process automation, and motor drives and power supplies.

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. 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 17 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: 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, 18 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. Some jurisdictions have already passing such laws. For example, California enacted legislation in 2023 requiring disclosure of certain companies’ greenhouse gas (GHG) emissions, climate-related financial risks, voluntary carbon offsets (VCOs), and certain climate-related emission claims. 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, consequences, may have a material adverse impact on our business and results of operations. including the imposition of tariffs and the resulting 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 65% of the Company’s net sales in fiscal 2023, including approximately 23% to China, which decreased from 25% in fiscal 2022. Economic conditions in China have been, and may continue to be, volatile and uncertain. In addition, the legal and regulatory system in China continues to evolve and is subject to change. There also continues to be significant uncertainty about the relationship between the U.S. and China, including with respect to geopolitics, trade policies, treaties, government regulations, and tariffs. Further deterioration of economic conditions or outlook, such as lower economic growth, recession or fears of recession in China may adversely affect the demand for or profitability of our products and services. 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; 19 • • • • • • • • transportation delays and interruptions; labor unrest; natural disasters; terrorist activities; war and acts of war public health concerns, including the outbreak of the coronavirus or other pandemics; difficulties in staffing and managing multi-national operations; and 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. 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: 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. The Organization for Economic Cooperation and Development (‘‘OECD’’) has been 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 of 15%, on a country-by-country-basis. As part of this effort, in December of 2021, the OECD published model rules to assist with implementation of the minimum tax regime. 20 In December of 2022, the European Union reached an agreement pursuant to which all European Union countries agreed to enact laws based upon the OECD-led minimum tax proposals. As of the end of 2023, many of the European Union countries have already enacted these rules effective for years beginning on or after December 31, 2023. Similar legislation was adopted, or is expected to be adopted, in other countries with widespread implementation of the global minimum tax anticipated by the end of 2025. The Company’s income tax rate in certain non-U.S. jurisdictions is lower than 15%. Once these minimum tax rules are effective, they could have a significant adverse effect on the Company’s future effective tax rate and cash flows. 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 expired at the end of 2022 but was later extended for an additional three years, retroactive to include all of 2023, as well as 2024 and 2025, and for the other subsidiary the tax holiday expired 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. 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. The Company monitors and manages exposures in changes in commodity prices, foreign currency exchange rates, and interest rates 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. 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; 21 • • • • • • • • 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. 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 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. 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. 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. 22 The volatility of the Company’s stock price could affect the value of an investment in the Company’s stock and future financial position. The market price of the Company’s stock can fluctuate widely. Between December 31, 2022 and December 30, 2023, the closing sale price of the Company’s common stock ranged between a low of $212.8 and a high of $309.9. 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 1C. CYBERSECURITY. The cybersecurity and data protection program at Littelfuse is based on foundational principles outlined in applicable industry and internationally accepted-cybersecurity frameworks. The Company has experienced and will continue to experience cyber-attacks, attempts to breach its systems, and other similar incidents, however we do not believe that the prior cyber incidents have materially affected or currently are reasonably likely to materially affect the Company. Littelfuse faces risks from cybersecurity threats that could have a material adverse effect on its business, financial 23 condition, results of operations, cash flows, or reputation. Like all cybersecurity programs, there is no guarantee that every attack method and technique has been fully addressed, as these change constantly, but Littelfuse is diligent in its attempts to protect data of the Company and its stakeholders. Littelfuse strives to assess and update its cybersecurity program on a regular basis using an Information Security Management System (ISMS) comprised of three main elements – 1) independent internationally recognized vendors and technologies for assessments and monitoring, 2) strong internal controls based on industry standards, and 3) Board and Senior Leadership governance and support. From an external assessment and monitoring perspective, Littelfuse engages third parties to monitor and report on known exploitable vulnerabilities, within and external to Littelfuse’s information technology (IT) ecosystems. These third parties provide assessment and vulnerability scanning tools to detect exploitable unauthorized access into the Littelfuse environments. The Audit Committee of the Board of Directors is tasked with reviewing the Company’s policies and procedures related to cybersecurity risks and incidents. The Company’s Chief Information Officer (‘‘CIO’’) oversees its cybersecurity program, and regularly provides updates to Littelfuse Senior Leadership and the Audit Committee, as well as the full Board, which include information regarding our cybersecurity program initiatives, insurance coverage, acquisition integration processes, program performance as well as the maturity of the Littelfuse cybersecurity program. These cybersecurity maturity updates are based on cybersecurity maturity reporting and analysis by the Littelfuse internal IT team, as well as reporting provided by independent third parties. The updates help Senior Leadership, the Audit Committee, and the Board to understand the risks the organization faces based on changing cybersecurity threats and on changes to the Littelfuse environment due to factors such as acquisitions and new technology upgrades and improvements. Representatives from Littelfuse’s technology team and other business functions receive regular cybersecurity risk reports and use this information for its decision making in operational improvements as well as budget and resource allocations. The CIO has managed and evolved the cyber security function at Littelfuse for the past five years and is supported by a cyber security leader with over 20 years of Littelfuse experience in IT infrastructure, IT operations, and cybersecurity. The ISMS within Littelfuse consists of internationally recognized program elements that reduce the risk of an operational or cybersecurity incident from significantly impacting Littelfuse and its customers, vendors, and employees. These ISMS elements include but are not limited to: Security Awareness and Training – Littelfuse has an IT security awareness program consisting of training on the fundamentals of information security protection. These training courses are provided annually. Network Protection – Network protection, detection, and monitoring technologies have been deployed on all external and internal network connections to segment different sections of the business from each other to strengthen key protection capabilities. Identity and Access Management (IAM) – Littelfuse has implemented user authentication controls on its systems, devices, data, and applications. In addition, multi-factor authentication is implemented for all personnel who remotely access or have privileged account access to Littelfuse systems and networks. Data Classification and Protection – Littelfuse has implemented data loss prevention and classification labels and encryption on its internal unstructured data to prevent unauthorized data loss and data sharing. Structured data in ERP systems and core business systems are encrypted and protected by industry cybersecurity standards and procedures. Endpoint Protection – Littelfuse has implemented anti-virus, malware, and endpoint protection management detection and monitoring solutions on end-user devices and servers. Logs and alerts from these monitoring solutions are routed to independent third-party monitoring vendors that provide 24/7 monitoring, around the world. Threat and Vulnerability Management – Littelfuse uses an internationally recognized managed security services provider (MSSP) and technologies to collect security alert and audit logs on a 24/7 basis, monitor and assess latest threat intelligence, provide analysis on new identified potential vulnerabilities, and provide response and support services to rapidly reduce any identified vulnerabilities. 24 Security Incident Management – Security incident response plans and procedures have been developed in collaboration with our MSSP. They allow us to assess potential threats, first and second level notification and response protocols, and supporting notification protocols – both internally and externally. These plans, procedures, and protocols are tested and updated on a regular basis. Resiliency and Contingency Planning – Risk assessments are performed on a regular basis to assess the IT risk of single points of failure, security maturity, and security vulnerabilities. The results of these assessments are used to define various resiliency and contingency mitigation strategies, corrective action plans, on-site and remote data back-up strategies and technologies and allocation of IT resources. ITEM 2. PROPERTIES. The Company’s engineering and research and development, manufacturing, sales, warehouses, and distribution centers are located in approximately 76 owned or leased facilities worldwide with primary operations in China, France, Germany, India, Ireland, Italy, Japan, Lithuania, Mexico, Netherlands, Philippines, South Korea, Spain, U.K, the U.S., and Vietnam totaling approximately 5.0 million square feet. The Company’s owned facilities include approximately 2.6 million square feet and the Company’s leased facilities include approximately 2.4 million square feet. The Company’s corporate headquarters is located in the U.S. in Chicago, Illinois. The Company believes its facilities are adequate to meet its requirements for the foreseeable future. ITEM 3.

[RESERVED.] ITEM 7. 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. 2023 EXECUTIVE OVERVIEW Net sales were $2,362.7 million, which decreased by $151.2 million or 6.0% in 2023 compared to 2022 including $0.7 million favorable changes in foreign exchange rates. The decrease was primarily driven by lower volume in the Electronics segment and the commercial vehicle business within the Transportation segment that more than offset $91.9 million or 3.7% of incremental net sales from the C&K acquisition within the Electronics segment and $13.2 million or 0.5% of net sales from the Western Automation acquisition within the Industrial segment. The Company recognized net income of $259.5 million, or $10.34 per diluted share, in 2023 compared to net income of $373.3 million, or $14.94 per diluted share in 2022. The decrease in net income was primarily due to lower operating income of $131.0 million in the Electronics segment and $29.9 million in the Transportation segment mainly driven by the commercial vehicle business. Net cash provided by operating activities was $457.4 million for the fiscal year ended December 30, 2023 representing an increase of $37.7 million as compared to the fiscal year ended December 31, 2022. The increase in net cash provided by operating activities was primarily due to reductions in working capital partially offset by lower cash earnings. On June 28, 2023, the Company entered into a definitive purchase agreement to acquire a 200mm wafer fab located in Dortmund, Germany (‘‘Dortmund Fab’’) from Elmos Semiconductor SE. The acquisition of the Dortmund Fab is expected to close in early fiscal year 2025. The total purchase price for the fab is approximately 93 million Euro, of which 37.2 million Euro down payment (approximately $40.5 million) was made with cash on hand and recorded in Other long-term assets in the Consolidated Balance Sheets was paid in the third quarter after regulatory approvals and approximately 56 million Euro will be paid at closing. The transaction did not have a material impact on the Company’s fiscal year 2023 financial results and is not expected to have material impact on the Company’s 2024 financial results and will be reported in the semiconductor business within the Company’s Electronics segment. On February 3, 2023, the Company completed the acquisition of Western Automation for approximately $162 million in cash. Headquartered in Galway, Ireland, Western Automation is a designer and manufacturer of electrical shock protection devices used across a broad range of high-growth end markets, including e-Mobility off-board charging infrastructure, industrial safety and renewables. At the time the Company and Western Automation entered into the definitive agreement, Western Automation had annualized sales of approximately $25 million. The business is reported within the Company’s Industrial segment. The Company financed the transaction with cash on hand. Risks Related to Market Conditions The Company continues to operate in a challenging macro environment, including but not limited to, supply chain disruptions, varying regional dynamics, and some pockets of end market softness. The ongoing war in Ukraine has had a minimal impact on the Company, as the Company suspended sales into and purchases from Russia. The Company does not have any direct operations in Ukraine or Russia. 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. 29 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, marine and aerospace. The Company is a key enabler of electrification, or eMobility, across these transportation applications. The Company is also a key enabler of electronification advancements across these transportation applications. 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. the Company’s products are found in renewable energy and energy storage Within industrial end markets, applications, HVAC, factory automation and industrial safety, industrial motor drives and power conversion, EV charging infrastructure, 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 and safety. Within electronics end markets, the Company’s products are found in data center, cloud storage and telecom infrastructure applications, building technologies and automation, appliances, medical devices, gaming and entertainment applications and mobile electronics. 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 advancements 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 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 Double-digit sales growth 5-7% average 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 (free cash flow) 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 • • • • • • • • • • • • • Priorities Increase product content with existing and new customers, and expand market share Expand presence (i.e. with portfolio and infrastructure) into new and underpenetrated, high-growth geographies and end markets Increase innovation capabilities and investments Leverage breadth of go-to-market strategies Target mergers and acquisitions that 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 30 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, expanding its digital presence, capitalizing on cross segment opportunities, and gaining traction in niche, high-growth end markets. The Company also leverages strategic acquisitions to enhance 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 businesses, products, markets, and technologies while leveraging existing customers and targeting new customers. Management believes profitable growth through a combination of organic growth and strategic acquisitions is critical to the Company’s competitiveness, while enhancing the value it delivers to all of its stakeholders. In addition, the Company continues to implement initiatives across all businesses to enhance productivity, and its commercial and operational capabilities, while managing its cost structure to align with business conditions, and the markets it serves. Primary areas of focus include optimizing its global operations, successfully integrating strategic acquisitions, and streamlining administrative and support activities to drive improved operating margins. The Company seeks to deploy its capital consistent with its 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 The preparation of financial statements in conformity with generally accepted accounting principle (‘‘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. There were no impairment charges recorded during the fiscal years of 2023, 2022 and 2021. 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 31 of the goodwill impairment test as of October 1, 2023 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 2023 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 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 23% and 369% of their respective estimated fair values. As of the most recent annual test conducted on October 1, 2023, the Company noted that the excess of fair value over the carrying value was 110%, 80%, 126%, 47%, 58%, 23%, and 369% for its reporting units: Electronics-Passive Products and Sensors, Electronics-Semiconductor, Passenger Car Products, Commercial Vehicle Products, Automotive Sensors, Industrial Controls and Sensors, and Industrial Circuit Protection, 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 12.6% for the Electronics-Passive Products and Sensors, Electronics-Semiconductor, Passenger Car Products, Commercial Vehicle Products, Automotive Sensors, and Industrial Circuit Protection reporting units, and 16.8% for the Industrial Controls and Sensors 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 32 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 Financial Accounting Standards Board (‘‘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 December 30, 2023, December 31, 2022, and January 1, 2022, 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.

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. 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, 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 Credit Losses 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 34 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 credit losses 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. 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 30, 2023, the Company recognized a $3.9 million impairment charge related to the land and building of a property in the commercial vehicle business within the Transportation segment that the Company made the decision to donate, a $0.9 million impairment charge substantially related to certain patents in a business within the Industrial segment, and a $0.1 million impairment on certain machinery and equipment in the semiconductor business within the Electronics segment. For the fiscal year ended December 31, 2022, the Company recorded a $2.9 million non-cash impairment charge for certain acquired technology and patent intangible assets due to a change in use and projected cash flows within the Electronics segment. Additionally, the Company recorded a non-cash impairment charge of $1.7 million for certain machinery and equipment within the Electronics segment due to a decision to cease further production of a product line during the fourth quarter of 2022. 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. The Company believes that the assumptions utilized in recording its obligations under its plans are reasonable based on its 35 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 December 30, 2023 and December 31, 2022 were 5.6% and 5.8%, respectively. A 50 basis point change in the discount rates at December 30, 2023 would have the following effect on the projected benefit obligation: (in millions) 0.5% Increase 0.5% Decrease Projected benefit obligation . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . $(3.8) $4.1 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, 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 $25.7 million, $24.6 million, and $21.4 million in 2023, 2022, and 2021, 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. 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 DECEMBER 30, 2023 AS COMPARED TO THE YEAR ENDED DECEMBER 31, 2022 fees and other Fiscal year 2023 included $28.2 million of non-segment charges, of which $11.7 million related to legal and professional integration expenses related to completed and contemplated acquisitions and $16.5 million of restructuring, impairment and other charges, primarily associated with employee termination costs and a $3.9 million impairment charge for the land and building in the commercial vehicle business within the Transportation segment. See Note 8, Restructuring, Impairment and Other Charges, for further discussion. Fiscal year 2022 included $43.2 million of non-segment charges, of which $17.6 million related to legal and professional fees and other integration expenses primarily associated with the C&K and Carling acquisitions and other contemplated acquisitions, $15.6 million of purchase accounting inventory step-up charges, and $10.0 million of restructuring, impairment and other charges, primarily related to employee termination costs and a $2.9 million intangible asset impairment charge within the Electronics segment in the fourth quarter of 2022.

The sales decrease was primarily due to lower volume in the Electronics segment and the commercial vehicle business within the Transportation segment that more than offset $105.1 million or 4.2% of incremental net sales from the C&K and Western Automation acquisitions and higher volume from the Industrial segment. Cost of Sales Cost of sales was $1,462.4 million, or 61.9% of net sales, in 2023, compared to $1,507.0 million, or 59.9% of net sales, in 2022. As a percent of net sales, cost of sales increased 2.0% driven by lower volume in the Electronics segment and the commercial vehicle business within the Transportation segment, partially offset by volume leverage and favorable product mix from the Industrial segment compared to 2022, and $15.6 million or 0.6% of purchase accounting inventory charges recorded during 2022. Gross Profit Gross profit was $900.2 million, or 38.1% of net sales, in 2023, compared to $1,006.9 million, or 40.1% of net sales, in 2022. The $106.7 million decrease in gross profit was primarily due to lower volume in the Electronics segment and the commercial vehicle business within the Transportation segment, partially offset by the acquisition of C&K within the Electronics segment, and volume leverage and favorable product mix from the Industrial segment and $15.6 million or 0.6% of purchase accounting inventory charges recorded during the first nine months of 2022. Operating Expenses Total operating expenses were $539.4 million, or 22.8% of net sales, for 2023 compared to $506.1 million, or 20.1% of net sales, for 2022. The increase in operating expenses of $33.3 million was primarily due to higher selling, general, and administrative expenses of $9.8 million, higher amortization expense of $10.1 million and research and development expenses of $6.8 million mainly due to the C&K and Western Automation acquisitions. Additionally, the Company incurred an increase in restructuring, impairment, and other charges of $6.5 million primarily related to the reorganization of certain manufacturing, selling and administrative functions within the Transportation and Industrial segments and a $3.9 million impairment charge related to the land and building of a property in the commercial vehicle business within the Transportation segment. This increase in operating expenses was partially offset by lower variable incentive compensation expense. Operating Income Operating income for 2023 was $360.9 million, a decrease of $140.0 million or 27.9% compared to $500.8 million for 2022. The decrease in operating income was due to lower gross profit from the Electronics and Transportation segments and higher operating expenses as noted above. Operating margins decreased from 19.9% in 2022 to 15.3% in 2023 primarily driven by lower volume in the Electronics and Transportation segments and the higher operating expenses mentioned above. 37 Income Before Income Taxes Income before income taxes for 2023 was $328.6 million, or 13.9% of net sales compared to $443.0 million, or 17.6% of net sales, for 2022. In addition to the factors impacting comparative results for operating income discussed above, income before income taxes was primarily benefited by lower foreign exchange losses of $12.1 million and lower unrealized losses of $13.7 million related to one of the Company’s equity investments for 2023 compared to 2022. Income Taxes Income tax expense for 2023 was $69.1 million, or an effective tax rate of 21.0%, compared to income tax expense of $69.7 million, or an effective tax rate of 15.7% for 2022. The effective tax rate for 2023 is higher than the effective tax rate for 2022, primarily due to less income earned in lower tax jurisdictions in 2023, as well as one-time tax benefits in 2022 resulting from losses on investments in the stock of two of the Company’s affiliates. The effective tax rate for 2022 was lower than the applicable U.S. statutory tax rate primarily due to income earned in lower tax jurisdictions as well as the impact of the one-time deductions previously noted.

See Note 8, Restructuring, Impairment and Other Charges, for further discussion. Included in ‘‘Other’’ Operating income for 2022 was $43.2 million of non-segment charges, of which $17.6 million of legal and professional fees and other integration expenses related to completed and contemplated acquisitions, $15.6 million of purchase accounting inventory step-up charges, and $10.0 million of restructuring, impairment and other charges, primarily related to employee termination costs and a $2.9 million non-cash impairment charge for certain acquired technology and patent intangible assets due to a change in use and projected cash flows within the Electronics segment in the fourth quarter of 2022. See Note 8, Restructuring, Impairment and Other Charges, for further discussion. Electronics Segment Net Sales Net sales for the Electronics segment decreased $142.4 million, or 9.5%, in 2023 compared to 2022 and included favorable changes in foreign exchange rates of $2.1 million or 0.1%. The sales decrease was mainly due to lower 38 volume from the Electronics products business driven by inventory rebalancing at certain distributors and reduced demand across certain electronics markets, including consumer facing and personal electronics, and telecom, which more than offset the incremental net sales of $91.9 million from the C&K acquisition. Operating Income Operating income was $300.6 million, representing a decrease of $131.0 million, or 30.4%, in 2023 compared to $431.6 million in 2022. The decrease in operating income was primarily due to lower volume mainly driven from the Electronics products business, which more than offset the incremental volume from the C&K acquisition. Operating margins decreased from 28.9% in 2022 to 22.3% in 2023 primarily due to the lower volume. Transportation Segment Net Sales Net sales in the Transportation segment decreased $37.9 million, or 5.3%, in 2023 compared to 2022 and included unfavorable changes in foreign exchange rates of $0.7 million or 0.1%. The commercial vehicle business net sales declined $50.9 million, largely driven by reduced demand largely due to inventory rebalancing at certain distributors and customers, and some demand reduction in commercial vehicle end markets. The automotive sensors business had net sales declines of $3.4 million primarily due to lower demand in the United States and China. These declines were partially offset by an increase of $16.5 million from the passenger car products business driven by the ongoing electronification and electrification of vehicles and global passenger vehicle production growth. Operating Income Operating income was $33.7 million, representing a decrease of $29.8 million, or 47.0%, in 2023 compared to $63.5 million in 2022. Operating margins declined from 8.9% to 5.0% primarily due to lower volume from the commercial vehicle business, partially offset by higher volume and price realization in the passenger car business. Industrial Segment Net Sales The Industrial segment net sales increased by $29.1 million, or 9.5%, in 2023 compared to 2022 and included unfavorable changes in foreign exchange rates of $0.7 million or 0.2%. The increase in net sales was primarily due to higher volume across multiple end markets, and the acquisition of Western Automation. Operating Income Operating income was $54.8 million, representing an increase of $5.9 million, or 12.1%, in 2023 compared to $48.9 million in 2022. The increase in operating income was due to price realization and higher volume, partially offset by higher amortization expenses from the acquisition of Western Automation. Operating margins were 16.4% in 2023 compared to 16.0% in 2022. Geographic Net Sales Information Net sales by geography represent net sales to customer or distributor locations.

The remaining increase of $110.3 million in the Electronics segment was due to higher volume and price realization across numerous end markets while the Industrial segment increased $53.8 million as a result of higher volume and price realization. 40 Cost of Sales Cost of sales was $1,507.0 million, or 59.9% of net sales, in 2022, compared to $1,308.0 million, or 62.9% of net sales, in 2021. The increase in cost of sales was primarily due to greater volume across the Electronics and Industrial segments driven by the factors discussed above along with the acquisitions of Carling and C&K. As a percent of net sales, cost of sales decreased 3.0% driven by volume leverage, partially offset by higher purchase accounting inventory charges of $7.2 million or 0.2% compared to 2021. Gross Profit Gross profit was $1,006.9 million, or 40.1% of net sales, in 2022, compared to $771.9 million, or 37.1% of net sales, in 2021. The $235.0 million increase in gross profit was primarily due to higher volume and price realization in the Electronics and Industrial segments along with the acquisitions of Carling and C&K. The increase in gross margin of 3.0% was primarily driven by volume leverage and price realization, partially offset by higher purchase accounting inventory charges of $7.2 million or 0.2% compared to 2021. Operating Expenses Total operating expenses were $506.1 million, or 20.1% of net sales, for 2022 compared to $386.3 million, or 18.6% of net sales, for 2021. The increase in operating expenses of $119.8 million was primarily due to higher selling, general, and administrative expenses, which increased by $69.4 million, research and development expenses, which increased by $29.7 million and increased amortization expense of $13.0 million and acquisition-related expenses of $10.6 million largely due to the Carling and C&K acquisitions. Operating Income Operating income for 2022 was $500.8 million, an increase of $115.2 million or 29.9% compared to $385.6 million for 2021. The increase in operating income was primarily due to higher gross profit across from Electronics and Industrial segments, partially offset by higher operating expenses as discussed above. Operating margins increased from 18.5% in 2021 to 19.9% in 2022 primarily driven by higher operating income in the Electronics segment of $122.0 million. Income Before Income Taxes Income before income taxes for 2022 was $443.0 million, or 17.6% of net sales compared to $341.0 million, or 16.4% of net sales, for 2021. In addition to the factors impacting comparative results for operating income discussed above, income before income taxes was impacted by $14.0 million of unrealized losses during 2022 compared to unrealized gains of $8.8 million during 2021 related to the Company’s equity investment, higher interest expense of $7.7 million due to an increase in borrowings outstanding, and higher foreign exchange losses of $7.2 million compared to 2021, partially offset by a $19.9 million non-cash pension settlement charge recognized in 2021. Income Taxes Income tax expense for 2022 was $69.7 million, or an effective tax rate of 15.7%, compared to income tax expense of $57.2 million, or an effective tax rate of 16.8% for 2021. 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 2022 is lower than the effective tax rate for 2021, primarily due to one-time tax benefits resulting from losses on investments in the stock of two of the Company’s affiliates.

Of the $376.9 million, at tax consequences, although in certain cases a non-U.S. withholding tax would be payable but subsequently refunded. With respect to the remaining $162.6 million, the Company has recognized deferred tax liabilities on approximately $106.3 million as of December 30, 2023 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 and 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 June 30, 2022, the Company amended and restated its Credit Agreement, dated as of April 3, 2020 (as so amended and restated, the ‘‘Credit Agreement’’) to effect certain changes, including, among other changes: (i) adding a $300 million unsecured term loan credit facility; (ii) making certain financial and non-financial covenants less restrictive on the Company and its subsidiaries; (iii) replacing LIBOR-based interest rate benchmarks and modifying performance-based interest rate margins; and (iv) extending the maturity date to June 30, 2027 (the ‘‘Maturity Date’’). Pursuant to the Credit Agreement, the Company may, from time to time, increase the size of the revolving credit facility or enter into one or more tranches of term loans in minimum increments of $25 million if there is no event of default and the Company is in compliance with certain financial covenants. Loans made under the available credit facility pursuant to the Credit Agreement (‘‘the Credit Facility’’) bear interest at the Company’s option, at either Secured Overnight Financing Rate (‘‘SOFR’’), fixed for interest periods of one, two, three or six-month periods, plus 1.00% to 1.75%, plus a SOFR adjustment of 0.10% or at the bank’s Base Rate, as defined in the Credit Agreement, plus 0.00% to 0.75%, based upon the Company’s Consolidated Leverage Ratio, as defined in the Credit Agreement. The Company is also required to pay commitment fees on unused portions of the Credit Facility ranging from 0.10% to 0.175%, based on the Consolidated Leverage Ratio, as defined in the Credit Agreement. The Credit Agreement includes representations, covenants and events of default that are customary for financing transactions of this nature. Under the Credit Agreement, revolving loans may be borrowed, repaid and reborrowed until the Maturity Date, at which time all amounts borrowed must be repaid. The Company borrowed $300.0 million under a term loan on June 30, 2022. The principal balance of the term loans must be repaid in quarterly installments on the last day of each calendar quarter in the amount of $1.9 million commencing September 30, 2022, through June 30, 2024, and in the amount of $3.8 million commencing September 30, 2024, through March 31, 2027, with the remaining outstanding principal balance payable in full on the Maturity Date.

During the fiscal year ended December 30, 2023, the Company made term loan payments of $7.5 million. The revolving loan and term loan balance under the Credit Facility was $100.0 million and $288.8 million, respectively, as of December 30, 2023. On May 12, 2022, the Company entered into an interest rate swap agreement to manage interest rate risk exposure, effectively converting the interest rate on the Company’s SOFR based floating-rate loans to a fixed-rate. The interest rate swap, with a notional value of $200 million, was designated as a cash flow hedge against the variability of cash flows associated with the Company’s SOFR based loans scheduled to mature on June 30, 2027. 44 As of December 30, 2023, the effective interest rate on unhedged portion of the outstanding borrowings under the credit facility was 6.71%, and 4.13% on the hedged portion.

Interest Rate Risk On June 30, 2022, the Company amended and restated its Credit Agreement, dated as of April 3, 2020 to effect certain changes, including, among other changes: (i) adding a $300 million unsecured term loan credit facility; (ii) making certain financial and non-financial covenants less restrictive on the Company and its subsidiaries; (iii) replacing LIBOR-based interest rate benchmarks and modifying performance-based interest rate margins; and (iv) extending the maturity date to June 30, 2027 (the ‘‘Maturity Date’’). Pursuant to the Credit Agreement, the Company may, from time to time, increase the size of the revolving credit facility or enter into one or more tranches of term loans in minimum increments of $25 million if there is no event of default and the Company is in compliance with certain financial covenants. The revolving loan and term loan balance under the Credit Facility was $100.0 million and $288.8 million, respectively, as of December 30, 2023. On May 12, 2022, the Company entered into an interest rate swap agreement to manage interest rate risk exposure, effectively converting the interest rate on the Company’s SOFR based floating-rate loans to a fixed-rate. The interest rate swap, with a notional value of $200 million, was designated as a cash flow hedge against the variability of cash flows associated with the Company’s SOFR based loans scheduled to mature on June 30, 2027. The cash flow hedge reduces the Company exposure to future interest rate fluctuation. After consideration of the hedge above, the remaining borrowings of $188.8 million, which represents approximately 20% of the Company’s total debt, is subject to future interest rate fluctuations which could potentially have a negative impact on the Company’s cash flows. 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 $1.9 million in annual interest expense. This exposure would be partially if not fully offset by higher interest income from the Company’s investments. 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, France, Germany, India, Ireland, Mexico, Philippines, U.K., Japan, Lithuania, Netherlands, Portugal, Singapore, South Korea, Spain, U.S., and Vietnam. During 2023, sales to customers outside the U.S. were approximately 65% of total net sales. During 2022, sales to customers outside the U.S. were approximately 64% 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 December 30, 2023, the net value of the Company’s assets with exposure to foreign currency risk was approximately $38 million, with the largest exposure being a Japanese Yen denominated inter-company loan with a U.S. Dollars 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 $3.8 million at December 30, 2023. At December 30, 2023, the net value of the Company’s liabilities with exposure to foreign currency risk was $6.5 million, with the largest exposure being U.S. Dollar denominated inter-company loans with a Mexican Peso 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 $0.6 million at December 30, 2023. 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, has taken and may take various actions in the future, including price increases and productivity improvements to mitigate any negative impacts of these exposures. 50 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 December 30, 2023 and December 31, 2022, the related consolidated statements of net income, comprehensive income, equity, and cash flows for each of the three years in the period ended December 30, 2023, 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 December 30, 2023 and December 31, 2022, and the results of its operations and its cash flows for each of the three years in the period ended December 30, 2023, in conformity with accounting principles generally accepted in the United States of America. We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (‘‘PCAOB’’), the Company’s internal control over financial reporting as of December 30, 2023, 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 16, 2024 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 critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates. Business Acquisition – Western Automation – Valuation of acquired intangible assets As discussed in Note 2, the Company acquired Western Automation (‘‘Western Automation’’), on February 3, 2023 for a total purchase price of approximately $158 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 $68 million. We identified the valuation of acquired Western Automation intangible assets as a critical audit matter. The principal considerations for our determination that the valuation of acquired Western Automation 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 management’s significant assumptions relating to the projected forecasted information including revenue growth rate, weighted average cost of capital (WACC), royalty rate, and customer attrition rate and (iii) the audit effort involved the use of professionals with specialized skill and knowledge. 52 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 including review of the valuation model, significant assumptions used, and the valuation process, completeness and accuracy of the underlying data used we tested the projected financial information including forecasted revenue growth rate 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 assumptions and methodologies used in developing the WACC, royalty rates, and customer attrition 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 16, 2024 53 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 December 30, 2023, 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 December 30, 2023, 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 December 30, 2023, and our report dated February 16, 2024 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. 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 16, 2024 54 LITTELFUSE, INC.

Summary of Significant Accounting Policies and Other Information Nature of Operations Littelfuse, Inc. and subsidiaries (the ‘‘Company’’) is a diversified, industrial technology manufacturing company empowering a sustainable, connected, and safer world. Across more than 20 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 ‘‘2023’’, ‘‘fiscal 2023’’ or ‘‘fiscal year 2023’’ refer to the fiscal year ended December 30, 2023. References herein to ‘‘2022’’, ‘‘fiscal 2022’’ or ‘‘fiscal year 2022’’ refer to the fiscal year ended December 31, 2022. References herein to ‘‘2021’’, ‘‘fiscal 2021’’ or ‘‘fiscal year 2021’’ refer to the fiscal year ended January 1, 2022. 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 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 2022 and fiscal 2023 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 December 30, 2023 and December 31, 2022 reported within the Consolidated Balance Sheets that sum to the total of the same such amounts shown in the Consolidated Statement of Cash Flows.

As of December 30, 2023, (‘‘Polytronics’’). The Company’s Polytronics shares held at the end of fiscal 2023 and 2022 represent approximately 6.7% of total Polytronics shares outstanding for both years. The Polytronics investment is carried at fair value. The fair value of the Polytronics investment was €9.7 million (approximately $10.8 million) at December 30, 2023 and €10.0 million (approximately $10.7 million) at December 31, 2022. As a result of the Company’s acquisition of IXYS Corporation (‘‘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. The Company recognized gains of $0.5 million from its equity method investment for both the fiscal years ended December 30, 2023 and December 31, 2022. The balance of these equity method investments was $14.0 million and $13.5 million as of the fiscal years ended December 30, 2023 and December 31, 2022, respectively. See Note 18, Related Party Transactions, 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 December 30, 2023 and December 31, 2022, the investment securities balance was $20.1 million and $14.1 million, respectively, related to the plan and are included in Other long-term assets on the Consolidated Balance Sheets. Trade Receivables The Company performs credit evaluations of customers’ financial condition and generally does not require collateral. 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 net 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 35 years for buildings, three to 20 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 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 61 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS the annual goodwill impairment test as of October 1, 2023 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 October 1, 2023, the Company noted that the excess of fair value over the carrying value, was 110%, 80%, 126%, 47%, 58%, 23%, and 369% for its reporting units; Electronics-Passive Products and Sensors, Electronics- Semiconductor, Passenger Car Products, Commercial Vehicle Products, Automotive Sensors, Industrial Controls and Sensors, and Industrial Circuit Protection, 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. There were no impairment charges recorded during the fiscal years of 2023, 2022, and 2021. 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 December 30, 2023, 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 3 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 4 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 up to 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 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. 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. 62 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS Revenue Recognition Revenue Disaggregation The following table disaggregates the Company’s revenue by primary business units for the fiscal years ended December 30, 2023 and December 31, 2022: (in thousands) Fiscal Year Ended December 30, 2023 Electronics Segment Transportation Segment Industrial Segment Total Electronics – Semiconductor. . . . . . . . . . . . . . . . . . . . . . . . .

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 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 63 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 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, 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 Credit Losses 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 credit losses 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 December 30, 2023 and December 31, 2022, the Company’s allowance for credit losses was $2.2 million and $1.6 million, respectively. Additionally, the Company had $5.4 million and $4.8 million of trade receivables greater than 90 days past due as of December 30, 2023 and December 31, 2022, respectively. Advertising Costs The Company expenses advertising costs as incurred, which amounted to $4.0 million, $3.8 million, and $2.1 million in fiscal years 2023, 2022 and 2021, respectively, and are included as a component of selling, general, and administrative expenses. Shipping and Handling Fees and Costs Amounts billed to customers related to shipping and handling are classified as revenue. Costs incurred for shipping and handling of $15.4 million, $13.9 million, and $15.4 million in fiscal years 2023, 2022, and 2021, respectively, are classified in selling, general, and administrative expenses. 64 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 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 recognized in the Consolidated Statements of Net Income were losses of $12.3 million, $24.4 million, and $17.2 million in fiscal years 2023, 2022 and 2021, respectively. 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 accrued liabilities is an accrual related to former coal mining operations at Littelfuse GmbH (formerly known as Heinrich Industries, AG) for the amounts of €2.5 million ($2.7 million) and €1.6 million ($1.7 million) at December 30, 2023 and December 31, 2022, 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 (Income) Expense, Net Other (income) expense, 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 (income) expense. 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. 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’’). 65 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 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 December 30, 2023, totaling $8.2 million, is recorded in Other long-term liabilities, and the anticipated 2024 annual installment payment of $6.6 million is included in Accrued income taxes, on the Consolidated Balance Sheet as of December 30, 2023. In accordance with guidance issued by the Financial Accounting Standards Board (‘‘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 December 30, 2023, December 31, 2022 and January 1, 2022, 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, short-term investments, accounts receivable, accounts payable, and accrued liabilities 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 Issued Accounting Standards In December 2023, the FASB issued Accounting Standards Updates (‘‘ASU’’) No. 2023-09, ‘‘Income Taxes (Topic 740): Improvements to Income Tax Disclosures’’. The amendments in this update provide more transparency about income tax information through improvements to the income tax disclosure primarily related to the income tax rate reconciliation and income taxes paid information. These requirements include: (1) consistent categories and greater disaggregation of information in the rate reconciliation and (2) income taxes paid disaggregated by jurisdiction. The other amendments in this update improve the effectiveness and comparability of disclosures by (3) adding disclosures of pretax income (or loss) and income tax expense (or benefit), and (4) removing disclosures that are no longer considered cost beneficial or relevant. The guidance is effective for fiscal years beginning after December 15, 2024 with early adoption permitted. The adoption of this guidance will modify our disclosures in our Consolidated Financial Statements. In November 2023, the FASB issued ASU No. 2023-07, ‘‘Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures’’. The amendments in this update require additional detailed and enhanced information about reportable segments’ expense, including significant segment expenses and other segment items that bridge segment revenue, significant expenses to segment profit or loss. The ASU also requires disclosure of the title and position of the Chief Operating Decision Maker (‘‘CODM’’) on annual basis as well as an explanation of how CODM uses the reported measures and other disclosures. The amendments in this update do not change how a public entity identifies its operating segments, aggregates those operating segments, or applies the quantitative thresholds to determine its reportable segments. The guidance is effective for fiscal years beginning after December 15, 2023 with early adoption permitted. The adoption of this guidance will modify our disclosures in our Consolidated Financial Statements. In October 2023, the FASB issued ASU No. 2023-06, ‘‘Disclosure Improvements’’. The amendments in this update represent changes to clarify or improve the disclosure or presentation requirements of a variety of Topics in the ASC. 66 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS The Company may be affected by one or more of those amendments. The amendments in this ASU should be applied prospectively and will not be effective until June 30, 2027. The company is currently evaluating the potential effects of these amendments on its Consolidated Financial Statements. In March 2023, the FASB issued ASU No. 2023-01, ‘‘Leases (Topic 842): Common Control Arrangements’’. The standard requires that leasehold improvements associated with common control leases be: 1) Amortized by the lessee over the useful life of the leasehold improvements to the common control group (regardless of the lease term) as long as the lessee controls the use of the underlying asset (the leased asset) through a lease. However, if the lessor obtained the right to control the use of the underlying asset through a lease with another entity not within the same common control group, the amortization period may not exceed the amortization period of the common control group. 2) Accounted for as a transfer between entities under common control through an adjustment to equity (or net assets for not-for-profit entities) if, and when, the lessee no longer controls the use of the underlying asset. Additionally, those leasehold improvements are subject to the impairment guidance in Topic 360, Property, Plant, and Equipment. This standard is effective for fiscal years beginning after December 15, 2023 including interim periods within those fiscal years. The Company does not expect any material effect on the Company’s Consolidated Financial Statements. 2. Acquisitions 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 businesses are included in the Company’s Consolidated Financial Statements from the date of the acquisition. Dortmund Fab On June 28, 2023, the Company entered into a definitive purchase agreement to acquire a 200mm wafer fab located in Dortmund, Germany (‘‘Dortmund Fab’’) from Elmos Semiconductor SE. The acquisition of the Dortmund Fab is expected to close in early fiscal year 2025. The total purchase price for the fab is approximately 93 million Euro, of which 37.2 million Euro down payment (approximately $40.5 million) was made with cash on hand and recorded in Other long-term assets in the Consolidated Balance Sheets was paid in the third quarter after regulatory approvals and approximately 56 million Euro will be paid at closing. The transaction did not have a material impact on the Company’s fiscal year 2023 financial results and is not expected to have material impact on the Company’s 2024 financial results and will be reported in the semiconductor business within the Company’s Electronics segment. Western Automation On February 3, 2023, the Company completed the acquisition of Western Automation Research and Development Limited (‘‘Western Automation’’) for approximately $162 million in cash. Headquartered in Galway, Ireland, Western Automation is a designer and manufacturer of electrical shock protection devices used across a broad range of high-growth end markets, including e-Mobility off-board charging infrastructure, industrial safety and renewables. At the time the Company and Western Automation entered into the definitive agreement, Western Automation had annualized sales of approximately $25 million. The business is reported within the Company’s Industrial segment. The acquisition was funded with cash on hand. The total purchase consideration of $158.3 million, net of cash, has been allocated to assets acquired and liabilities assumed, as of the completion of the acquisition, based on estimated fair values.

The goodwill resulting from this acquisition consists largely of the Company’s expected future product sales and synergies from combining Western Automation’s products and technology with the Company’s existing Industrial products portfolio. Goodwill resulting from the Western Automation acquisition is not expected to be deductible for tax purposes. For the fiscal year ended December 30, 2023, the Company recorded measurement period adjustments to decrease accrued warranty liabilities of $0.9 million. As a result of these adjustments, goodwill was decreased by $0.9 million. Included in the Company’s Consolidated Statements of Net Income for the fiscal year ended December 30, 2023 are net sales of $13.2 million, and a loss before income taxes of $1.3 million, since the February 3, 2023 acquisition of Western Automation. For the fiscal year ended December 30, 2023, the Company incurred $1.2 million of legal and professional fees related to the Western Automation acquisition recognized as Selling, general, and administrative expenses and reflected as other non-segment costs. C&K Switches On July 19, 2022, the Company acquired C&K Switches (‘‘C&K’’) for $540 million in cash. Founded in 1928, C&K is a leading designer and manufacturer of high-performance electromechanical switches and interconnect solutions with a strong global presence across a broad range of end markets, including industrial, transportation, datacom, and aerospace.

The goodwill resulting from this acquisition consists largely of the Company’s expected future product sales and synergies from combining C&K’s products and technology with the Company’s existing Electronics products portfolio. Goodwill resulting from the C&K acquisition is not expected to be deductible for tax purposes. For the fiscal year ended December 30, 2023, the Company recorded measurement period adjustments to increase other non-current liabilities of $4.2 million associated with uncertain tax positions, income taxes payable of $0.2 million, and reduce accrued liabilities of $0.3 million and deferred tax liabilities of $0.2 million. As a result of these adjustments, goodwill was increased by $3.9 million. As required by purchase accounting rules, the Company recorded a $10.8 million step-up of inventory to its fair value as of the acquisition date. The step-up was amortized as a non-cash charge to cost of sales during the third and fourth quarter of 2022 as the acquired inventory was sold and reflected as other non-segment costs. For the fiscal year ended December 31, 2022, the Company incurred $9.1 million of legal and professional fees related to the C&K acquisition recognized as Selling, general, and administrative expenses and reflected as other non-segment costs. Embed On April 12, 2022, the Company acquired Embed Ltd. (‘‘Embed’’).

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. 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. The step-up was 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 was sold, and is reflected as other non-segment costs. The Company recognized a non-cash charge of $4.8 million and $1.6 million to cost of goods sold during the fiscal years ended December 31, 2022 and January 1, 2022, respectively. 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. Pro Forma Results The following table summarizes, on an unaudited pro forma basis, the combined results of operations of the Company and Western Automation as though the acquisition had occurred as of January 2, 2022, and C&K as though the acquisition had occurred as of December 27, 2020, and Carling as though the acquisitions had occurred as of December 29, 2019. The Company has not included pro forma results of operations for Embed as its operations were not material to the Company. The pro forma amounts presented are not necessarily indicative of either the actual consolidated results had the Western Automation acquisition occurred as of January 2, 2022, and had C&K acquisition occurred as of December 27, 2020 and had the Carling acquisitions occurred as of December 29, 2019 or of future consolidated operating results.

The transaction cost adjustments reflect the reversal of certain legal and professional fees from the twelve months ended December 30, 2023 and December 31, 2022, respectively, and recognition of those fees during the twelve months ended December 31, 2022. The amortization of inventory step-up adjustment reflects the reversal of the amount recognized during the twelve months ended December 31, 2022. The inventory step-up is amortized over four months for all acquisitions, as the inventory was sold. The interest expense adjustment reflects lower interest expense associated with the financing of the C&K acquisition that replaced higher pre-acquisition debt. 70 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 3.

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 2035. 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 and finance leases that were acquired through the C&K acquisition. 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. 73 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS The following table presents the classification of right of use assets and lease liabilities as of December 30, 2023 and December 31, 2022: (in thousands) Operating Leases Consolidated Balance Sheet Classification Fiscal Year Ended December 30, 2023 December 31, 2022 Right of use assets – operating lease Current operating lease liabilities Non-current operating lease liabilities Right of use lease assets . . . . . . . . . . . . . . . .

Revolving Credit Facility and Term Loan On June 30, 2022, the Company amended and restated its Credit Agreement, dated as of April 3, 2020 (as so amended and restated, the ‘‘Credit Agreement’’) to effect certain changes, including, among other changes: (i) adding a $300 million unsecured term loan credit facility; (ii) making certain financial and non-financial covenants less restrictive on the Company and its subsidiaries; (iii) replacing LIBOR-based interest rate benchmarks and modifying performance-based interest rate margins; and (iv) extending the maturity date to June 30, 2027 (the ‘‘Maturity Date’’). Pursuant to the Credit Agreement, the Company may, from time to time, increase the size of the revolving credit facility or enter into one or more tranches of term loans in minimum increments of $25 million if there is no event of default and the Company is in compliance with certain financial covenants. Loans made under the available credit facility pursuant to the Credit Agreement (‘‘the Credit Facility’’) bear interest at the Company’s option, at either SOFR, fixed for interest periods of one, two, three or six-month periods, plus 1.00% to 1.75%, plus a SOFR adjustment of 0.10% or at the bank’s Base Rate, as defined in the Credit Agreement, plus 0.00% to 0.75%, based upon the Company’s Consolidated Leverage Ratio, as defined in the Credit Agreement. The Company is also required to pay commitment fees on unused portions of the Credit Facility ranging from 0.10% to 0.175%, based on the Consolidated Leverage Ratio, as defined in the Credit Agreement. The Credit Agreement includes representations, covenants and events of default that are customary for financing transactions of this nature. Under the Credit Agreement, revolving loans may be borrowed, repaid and reborrowed until the Maturity Date, at which time all amounts borrowed must be repaid. The Company borrowed $300.0 million under a term loan on June 30, 2022. The principal balance of the term loans must be repaid in quarterly installments on the last day of each calendar quarter in the amount of $1.9 million commencing September 30, 2022, through June 30, 2024, and in the amount of $3.8 million commencing September 30, 2024, through March 31, 2027, with the remaining outstanding principal balance payable in full on the Maturity Date. Accrued interest on the loans is payable in arrears on each interest payment date applicable thereto and at such other times as may be specified in the Credit Agreement. Subject to certain conditions, (i) the Company may terminate or reduce the Aggregate Revolving Commitments, as defined in the Credit Agreement, in whole or in part, and (ii) the Company may prepay the revolving loans or the term loans at any time, without premium or penalty. During the fiscal year ended December 30, 2023, the Company made term loan payments of $7.5 million. The revolving loan and term loan balance under the Credit Facility was $100.0 million and $288.8 million, respectively, as of December 30, 2023. On May 12, 2022, the Company entered into an interest rate swap agreement to manage interest rate risk exposure, effectively converting the interest rate on the Company’s SOFR based floating-rate loans to a fixed-rate. The interest rate swap, with a notional value of $200 million, was designated as a cash flow hedge against the variability of cash flows associated with the Company’s SOFR based loans scheduled to mature on June 30, 2027. As of December 30, 2023, the effective interest rate on unhedged portion of the outstanding borrowings under the credit facility was 6.71%, and 4.13% on the hedged portion. As of December 30, 2023, the Company had $0.2 million outstanding in letters of credit and had available $599.8 million of borrowing capacity under the revolving credit facility. At December 30, 2023, the Company was in compliance with all covenants under the credit agreement.

Interest on the U.S. Senior Notes due 2025 and 2030 is payable on February 15 and August 15, commencing on August 15, 2018. On May 18, 2022, the above note purchase agreements were amended to, among other things, update certain terms, including financial covenants to be consistent with the terms of the restated Credit Agreement and the 2022 Purchase Agreement, as defined below. On May 18, 2022, the Company entered into a Note Purchase Agreement (‘‘2022 Purchase Agreement’’) pursuant to which the Company issued and funded on July 18, 2022 $100 million in aggregate principal amount of 4.33% Senior Notes, due June 30, 2032 (‘‘U.S. Senior Notes, due 2032’’) (together with the U.S. Senior Notes due 2025 and 2030, the Euro Senior Notes and the U.S. Senior Notes due 2022 and 2027, the ‘‘Senior Notes’’). Interest on the U.S. Senior Notes due 2032 is payable semiannually on June 30 and December 30, commencing on December 30, 2022. The Senior Notes have not been registered under the Securities Act, or applicable state securities laws.

The Senior Notes are subject to certain customary covenants, including limitations on the Company’s ability, with certain exceptions, to engage in mergers, consolidations, asset sales and transactions with affiliates, to engage in any business that would substantially change the general business of the Company, and to incur liens. In addition, the Company is required to satisfy certain financial covenants and tests relating to, among other matters, interest coverage and leverage. At December 30, 2023, the Company was in compliance with all covenants under the Senior Notes. The Company may redeem the Senior Notes upon the satisfaction of certain conditions and the payment of a make-whole amount to noteholders, and are required to offer to repurchase the Senior Notes at par following certain events, including a change of control. Debt Issuance Costs During fiscal year 2022, the Company paid debt issuance costs of $2.7 million in connection with the amended and restated Credit Agreement, dated June 30, 2022 which, along with the remaining balance of debt issuance costs of the previous credit facility, are being amortized over the life of the amended and restated Credit Agreement. 78 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS Debt Maturities Scheduled maturities of the Company’s long-term debt for each of the five years succeeding December 30, 2023 and thereafter are summarized as follows: (in thousands) 2024 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 2025 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 2026 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 2027 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 2028 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 2029 and thereafter . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

Fair Value of Assets and Liabilities 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. There were no transfers in or out of Level 1, Level 2 and Level 3 during the year ended December 30, 2023. 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, certificates of deposit, and short-term time deposits, which are held with institutions with sound credit ratings 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. Derivatives Designated as Hedging Instruments On May 12, 2022, the Company entered into an interest rate swap agreement to manage interest rate risk exposure, effectively converting the interest rate on the Company’s SOFR based floating-rate loans to a fixed-rate. The interest rate swap, with a notional value of $200 million, was designated as a cash flow hedge against the variability of cash flows associated with the Company’s SOFR based loans scheduled to mature on June 30, 2027. The fair value of the interest rate swap was valued using an independent third-party valuation model. Pursuant to this model, changes in fair value of derivatives that are designated as cash flow hedges are deferred in accumulated other comprehensive (loss) income until the underlying transactions are recognized in earnings. The primary inputs into the valuation of the interest rate swap are interest yield curves, interest rate volatility, credit risk, credit spreads and other market information. The interest rate swap is classified within Level 2 of the fair value hierarchy, since all significant inputs are corroborated by observable market data. 79 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS The use of derivatives creates exposure to credit risk relating to potential losses that could be recognized in the event that the counterparties to these instruments fail to perform their obligations under the contracts. The Company seeks to minimize this risk by limiting our counterparties to major financial institutions with acceptable credit ratings and monitoring the total value of positions with individual counterparties. In the event of a default by one of our counterparties, the Company may not receive payments provided for under the terms of our derivatives. Derivatives Not Designated as Hedging Instruments On July 14, 2022, the Company entered into a foreign currency exchange forward contract to mitigate the currency fluctuation risk between the Euro and U.S. dollar on its Euro denominated Senior Notes, Series A due 2023. The notional value of the forward contract at July 14, 2022 was €117 million and expired on December 7, 2023 with the final settlement value of $6.3 million which the Company used to convert USD to Euro to pay down the €117 million of Euro Senior Notes, Series A due 2023. The foreign currency contract was not designated as a hedge instrument and was marked to market on a monthly basis. As a result, changes in fair value during 2023 and 2022 are reported in Foreign exchange loss in the Consolidated Statements of Net Income.

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 December 30, 2023 and December 31, 2022, as the rates on these borrowings are variable in nature. 81 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS The carrying value and estimated fair values of the Company’s Euro Senior Notes, Series A and Series B and USD Senior Notes, Series A and Series B, as of December 30, 2023 and December 31, 2022 were as follows: (in thousands) Euro Senior Notes, Series A due 2023. . . . . . . . . . . . . . . . . . . . . .

Asset Allocation 2022 2023 3% 7% 90% 13% 14% 73% 100% 100% The Company segregated its plan assets by the following major categories and level for determining their fair value as of December 30, 2023 and December 31, 2022. 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. 85 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 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 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 86 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 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 December 30, 2023, December 31, 2022 and January 1, 2022. Employees are immediately vested in their contributions plus actual earnings thereon, as well as the Company contributions. Company matching contributions amounted to $7.7 million, $5.5 million, and $5.0 million in 2023, 2022, and 2021, 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 under the plan from its general assets. As of December 30, 2023, there was $20.1 million of marketable securities related to the plan included in Other assets and $20.1 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 $0.6 million, $0.2 million, and $0.2 million in 2023, 2022, and 2021, 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. During the fiscal year 2023, the Company designated an additional 0.7 million shares for the Company’s equity-based compensation plans. As of December 30, 2023, there were 1.2 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 total fair value of the vested RSU shares was $19.8 million, $15.4 million, and $18.9 million for 2023, 2022, and 2021, respectively. The total amount of share-based liabilities paid was $2.2 million, $1.1 million and $1.3 million for 2023, 2022, and 2021, 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 December 30, 2023, the unrecognized compensation cost for options and restricted shares was $22.1 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 $25.7 million, $24.6 million, and $21.4 million for 2023, 2022, and 2021, respectively. The total related income tax benefit recognized in the Consolidated Statements of Net Income was $3.8 million, $3.5 million and $3.3 million for 2023, 2022, and 2021, respectively. The Company uses the Black-Scholes option valuation model to determine the fair value of stock option awards granted.

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 28, 2021, the Company announced that the Board of Directors authorized a 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. There are $300 million in the aggregate of shares available for purchase under the program as of December 30, 2023. During the fiscal years 2023, 2022 and 2021, the Company did not repurchase any shares of its common stock. 88 Cash flow hedge . . . . . . . . . .

Income Taxes 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 December 30, 2023, totaling $8.2 million, is recorded in Other long-term liabilities, and the anticipated 2024 annual installment payment of $6.6 million is included in Accrued income taxes, on the Consolidated Balance Sheet as of December 30, 2023. 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 December 30, 2023, December 31, 2022, and January 1, 2022, 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.

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 (which begin expiring in 2025). 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 $81.1 million, $96.8 million, and $58.2 million in 2023, 2022, and 2021, respectively, and received income tax refunds of $7.2 million, $3.2 million, and $2.6 million in 2023, 2022, and 2021, 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 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 December 30, 2023, unremitted earnings of the Company’s non-U.S. subsidiaries were approximately $1.5 billion. A distribution of such earnings will generally not be subject to U.S. federal income tax. The Company recognized deferred tax liabilities of $18.6 million as of December 30, 2023 and $16.3 million as of December 31, 2022, 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 expired at the end of 2022, but was later extended for an additional three years, retroactive to include all of 2023, as well as 2024 and 2025, and for the other subsidiary the tax holiday expired at the end of 2023. The Company intends to seek an extension for the expired tax holiday. Together, the tax holidays contributed $5.8 million in tax benefits, or $0.23 per diluted share, during 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. 91 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS A reconciliation of the beginning and ending amount of unrecognized tax benefits as of December 30, 2023, December 31, 2022, and January 1, 2022 is as follows: (in thousands) Balance at January 1, 2022 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

Of this amount, approximately $7.8 million may be recognized in 2024 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 $0.5 million (net of a $1.7 million decrease due to a lapse in the statute of limitations), $1.4 million (net of a $0.2 million decrease due to a lapse in the statute of limitations) and $1.6 million (net of a $0.6 million decrease due to a lapse in the statute of limitations) in 2023, 2022, and 2021, respectively. Accrued interest for such matters included in Other long-term liabilities within the Consolidated Balance Sheets was $14.4 million and $11.8 million as of December 30, 2023 and December 31, 2022, 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 Germany, the Netherlands, Singapore, 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. 15.

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, electromechanical switches and interconnect solutions, 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 charging infrastructure, aerospace, power supplies, data centers and telecommunications, medical devices, alternative energy and energy storage, building and home automation, appliances, and mobile electronics. Transportation Segment: 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 and bus, off-road and recreational vehicles, material handling equipment, agricultural machinery, construction equipment 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 and bus, construction, agriculture, material handling and marine. Industrial Segment: Consists of industrial controls (protection relays, contactors, transformers, residual current devices, ground fault circuit interrupters, residual current monitors, and arc fault detection devices) and temperature sensors for use in various applications such as renewable energy and energy storage systems, industrial safety, factory automation, electric vehicle infrastructure, HVAC systems, non-residential construction, MRO, and mining. industrial circuit protection (industrial fuses), 93 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS The Company has provided this segment information for all comparable prior periods.

Sales to Arrow Electronics, Inc., which were included in the Electronics, Transportation, and Industrial segments, were 11.2%, 11.5%, and 10.7% of consolidated net sales in 2023, 2022, and 2021 respectively. No other single customer accounted for more than 10% of net sales during the last three years. 17. Commitments and Contingencies Off-Balance Sheet Arrangements As of December 30, 2023, the Company did not have any off-balance sheet arrangements, as defined under SEC rules. Specifically, the Company was not liable for guarantees of indebtedness owed by third parties, the Company was not directly liable for the debt of any unconsolidated entity and the Company did not have any retained or contingent interest in assets. 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. Product Warranty Liabilities Our policy is to accrue for warranty claims when a loss is both probable and estimable. Liabilities for warranty claims have historically not been material and in limited instances, customer may make claims for costs they incurred or other damages related to a claim. Environmental Remediation Liabilities Refer to Note 1: Summary of Significant Accounting Policies and Other Information related to environmental liabilities. Our operations and facilities are subject to U.S. and non-U.S. laws and regulations governing the protection of the environment and our employees, including those governing air emissions, chemical usage, water discharges, the management and disposal of hazardous substances and wastes, and the cleanup of contaminated sites. We could incur significant costs, including cleanup costs, fines, civil or criminal sanctions, or third-party property damage or personal injury claims, in the event of violations or liabilities under these laws and regulations, or 95 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS non-compliance with the environmental permits required at our facilities. Potentially significant expenditures could be required in order to comply with environmental laws that may be adopted or imposed in the future. We are, however, not aware of any threatened or pending material environmental investigations, lawsuits, or claims involving the Company or its operations. Legal Proceedings In the ordinary course of business, the Company may be involved in a number of claims and litigation matters. While it is not feasible to predict the outcome of these matters, based upon our experience and current information known to us, we do not expect the outcome of these matters, either individually or in the aggregate, to have a material adverse effect on our results of operations, financial position, and/or cash flows. The Company accounts for litigation and claims losses in accordance with FASB ASC Topic 450, Contingencies where loss contingency provisions are recognized for probable and estimable losses at our best estimate of a loss or, when a best estimate cannot be made, at our estimate of the minimum loss. These estimates require the application of considerable judgment and are refined each accounting period as additional information becomes known. We are often initially unable to develop a best estimate of loss and therefore the minimum amount, which could be an immaterial amount, is recognized. As information becomes known, either the minimum loss amount is increased, or a best estimate can be made, resulting in additional loss provisions. A best estimate may be changed to a lower amount when events result in an expectation of a more favorable outcome than previously expected. Pending Litigation and Claims There are no material pending litigation or claims outstanding as of December 30, 2023. 18.

CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE. None. ITEM 9A. CONTROLS AND PROCEDURES. 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 including the Chief Executive Officer and Chief Financial Officer, of the participation of its management, 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 December 30, 2023. 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. 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 December 30, 2023, based upon the updated framework in Internal Control — Integrated Framework (2013). Based on this assessment, the Company’s management concluded that, as of December 30, 2023, the Company’s internal control over financial reporting was effective. 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 year ended December 30, 2023, that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting. 97 ITEM 9B.

Includes 39,623 shares reserved for issuance upon vesting of outstanding restricted stock units under the IXYS Plans and 42,581 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.

(5) Includes 136,150 shares that remain available for future issuance under the IXYS Corporation 2016 Equity Incentive Plan. IXYS Plans In connection with the acquisition of IXYS, 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, 2011, 2013 Equity Incentive Plans expired in June 2019, June 2021 and June 2023, respectively, with no additional grants made after the expiration date. As of December 30, 2023, 136,150 shares remained available for issuance under the IXYS Plans. Zilog Plans 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, as of December 30, 2023, no shares remain available for issuance of new awards under the Zilog Plan and 3,457 stock options remain outstanding. 100 ITEM 12.
