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 allowances, 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 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 distributors 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 historical 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 historical 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.

Cash, Cash Equivalents, and Restricted Cash

The following table provides a reconciliation of cash, cash equivalents, and restricted cash at March 29, 2025 and December 28, 2024 reported within the Condensed Consolidated Balance Sheets that sum to the total of the same such amounts shown in the Condensed Consolidated Statement of Cash Flows.

Table of Contents


(in thousands)	March 29, 2025		December 28, 2024
Cash and cash equivalents	$	618,687	$	724,924

Total cash, cash equivalents, and restricted cash	$	620,256	$	726,437

Recently Issued Accounting Standards

In November 2024, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Updates ("ASU") No. 2024-03, "Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40)." The amendments in this update require disclosure, in the notes to financial statements, of specified information about certain costs and expenses. The amendments require that at each interim and annual reporting period an entity (a) disclose the amounts of (i) purchases of inventory, (ii) employee compensation, (iii) depreciation, (iv) intangible asset amortization, and (v) depreciation, depletion, and amortization recognized as part of oil and gas producing activities ("DD&A") included in each relevant expense caption. A relevant expense caption is an expense caption presented on the face of the income statement within continuing operations that contains any of the expense categories listed in (i)-(v); (b) include certain amounts that are already required to be disclosed under current GAAP in the same disclosure as the other disaggregation requirements; (c) disclose a qualitative description of the amounts remaining in relevant expense captions that are not separately disaggregated quantitatively; (d) disclose the total amount of selling expenses and, in annual reporting periods, an entity’s definition of selling expenses. The guidance is effective for fiscal years beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027, with early adoption permitted. The adoption of this guidance will increase the Company's disclosures in its Consolidated Financial Statements. The Company is currently evaluating the potential impact on the disclosures in the Company's Consolidated Financial Statements.

In December 2023, the FASB issued 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 disclosures in the Company's 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. 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.

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 business are included in the Company’s Condensed Consolidated Financial Statements from the date of the acquisition.

Dortmund Fab

On December 31, 2024, the Company completed the acquisition of a 200mm wafer fab located in Dortmund, Germany (“Dortmund Fab”) from Elmos Semiconductor SE. The total purchase price for the Dortmund Fab is approximately €94 million, of which a €37.2 million down payment (approximately $40.5 million) was paid in the third quarter of 2023 after regulatory approvals, and €56.7 million (approximately $58.8 million) was paid at closing. The business is reported in the Electronics-Semiconductor business within the Company’s Electronics segment.

Table of Contents

The acquisition was funded with cash on hand. The total purchase consideration of $95.9 million, net of cash acquired, has been allocated, on a preliminary basis, to assets acquired and liabilities assumed, as of the completion of the acquisition, based on estimated fair values. The purchase consideration is subject to change for the final working capital adjustments. The purchase price allocation is preliminary because the evaluations necessary to assess the fair values of the net assets acquired are still in process. The primary areas not yet finalized relate to the completion of the valuation of certain acquired income tax assets and liabilities and personal property. As a result, these allocations are subject to change during the purchase price allocation period as the valuations are finalized.

The following table summarizes the preliminary purchase price allocation of the fair value of assets acquired and liabilities assumed in the Dortmund Fab acquisition:


(in thousands)	Purchase Price Allocation
Total purchase consideration:
Cash, net of cash acquired	$	95,942
Allocation of consideration to assets acquired and liabilities assumed:
Trade receivables	5,985
Inventories	6,600
Other current assets	8,479
Property, plant, and equipment	30,132
Intangible assets	1,800
Goodwill	57,439
Other long-term assets	8,579
Current liabilities	(8,248)

Other long-term liabilities	(14,824)
	$	95,942

All Dortmund assets and liabilities were recorded in the Electronics segment and are primarily reflected in the Europe geographic area. The goodwill resulting from this acquisition consists largely of the Company’s expected future product sales and synergies from combining Dortmund Fab’s products and technology with the Company’s existing semiconductor products portfolio. Goodwill resulting from the Dortmund acquisition is expected to be deductible for tax purposes.

Included in the Company’s Condensed Consolidated Statements of Net Income for the three months ended March 29, 2025 were net sales of $10.2 million and income before income taxes was nil since the December 31, 2024 acquisition of Dortmund Fab.

As required by purchase accounting rules, the Company recorded a $0.5 million step-down of inventory to its fair value as of the acquisition date based on the preliminary valuation. The step-down was fully amortized as a non-cash credit to cost of sales during the first fiscal quarter of 2025 as the acquired inventory was sold and reflected as other non-segment costs.

During the three months ended March 30, 2024, the Company incurred approximately $0.1 million of legal and professional fees related to the Dortmund Fab acquisition recognized as Selling, general, and administrative expenses in the Condensed Consolidated Statements of Net Income. Total of $3.5 million of legal and professional fees related to the Dortmund Fab acquisition was recognized since 2023. These costs were reflected as other non-segment costs.

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. 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.

9. 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 or Level 3 during the period.

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 were 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 and recorded in Investments and Other long-term assets.

Derivatives Designated as Hedging Instruments

For derivatives that will be accounted for as hedging instruments, the Company formally designates and documents, at inception, the financial instrument as a hedge of a specific underlying exposure, the risk management objective and the strategy for undertaking the hedge transaction. In addition, the Company formally assesses, both at the inception and at least quarterly thereafter, whether the financial instruments used in hedging transactions are effective at offsetting changes in either the fair values or cash flows of the related underlying exposures. For highly effective cash flow hedges, ASC 815 requires the entire change in fair value of the hedging instrument included in the assessment of hedge effectiveness to be recorded in other comprehensive income. No components of the Company's hedging instruments were excluded from the assessment of hedge effectiveness.

Zero Cost Collar Agreement

In July 2024, the Company implemented a hedging program to manage foreign currency risk exposure related to fluctuations between the U.S. dollar and Mexican peso. These foreign currency zero cost collars are designated as cash flow hedges for a portion of our Mexican peso-denominated manufacturing expenses, predominantly salary expenses, vendor payments, and utility expenses. If the spot rate is between the weighted-average ceiling and floor rates on the date of maturity, then the Company would not owe or receive any payments under these collars. The Company plans to continue executing zero cost collars with 14-month rolling maturities as an ongoing strategy to hedge peso-denominated manufacturing expenses. The trade entry date, maturity date, weighted-average floor, and weighted-average ceiling for each collar trade was as follows:

Table of Contents


Trade Entry Date	Trade Maturity Date	Weighted-Average Floor	Weighted-Average Ceiling
July 3, 2024	August 29, 2025	18.0000	19.4350
August 5, 2024	September 29, 2025	19.6550	21.0000
September 3, 2024	November 3, 2025	20.0820	21.7571
September 30, 2024	November 26, 2025	19.8700	21.3650
November 4, 2024	January 2, 2026	20.1200	21.6900
December 3, 2024	February 2, 2026	20.4250	22.0377
January 2, 2025	March 2, 2026	20.8000	21.9082
February 6, 2025	March 30, 2026	20.5300	22.0000

The fair value of the collars was determined 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 until the underlying transactions are recognized in earnings. For the three months ended March 29, 2025, the Company recorded a pre-tax unrealized gain on the collars of $2.4 million. As of March 29, 2025, the Company estimates that approximately $1.1 million of pre-tax losses recorded in accumulated other comprehensive loss will be recognized in earnings over the next 12 months. The amounts included in accumulated other comprehensive income will be reclassified to earnings should the hedge no longer be considered effective. No amount of ineffectiveness was included in net income for the three months ended March 29, 2025. The Company will continue to assess the effectiveness of the hedge on an ongoing basis. The primary inputs into the valuation of the collars are interest yield curves, interest rate volatilities, foreign exchange rates, foreign exchange volatilities, credit risk, credit spreads and other market information. The collars are classified within Level 2 of the fair value hierarchy since all significant inputs are corroborated by market observable data.

Interest Rate Swap

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 until the underlying transactions are recognized in earnings. For the three months ended March 29, 2025, the Company recorded a pre-tax unrealized loss on the interest rate swap of $2.3 million. As of March 29, 2025, the Company estimates that approximately $2.3 million of pre-tax gain recorded in accumulated other comprehensive loss will be recognized in earnings over the next 12 months. 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 market observable data.

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 its 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 its counterparties, the Company may not receive payments provided for under the terms of its derivatives.

The Company does not enter into derivative financial instruments for trading purposes.

As of March 29, 2025 and December 28, 2024, the fair values of the Company's derivative financial instruments and their classifications on the Condensed Consolidated Balance Sheets were as follows:

Mutual Funds

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 marketable securities are classified as Level 1 under the fair value hierarchy as they are maintained in mutual funds with readily determinable fair value and recorded in Other long-term assets in the Condensed Consolidated Balance Sheets.

There were no changes during the quarter ended March 29, 2025 to the Company’s valuation techniques used to measure asset and liability fair values on a recurring basis. As of March 29, 2025 and December 28, 2024, the Company did not hold any non-financial assets or liabilities that are required to be measured at fair value on a recurring basis.

In addition to the methods and assumptions used for the financial instruments recorded at fair value as discussed above, the following methods and assumptions are used to estimate the fair value of other financial instruments that are not marked to market on a recurring basis. The Company’s other financial instruments include cash and cash equivalents, short-term investments, accounts receivable and its long-term debt. Due to their short-term maturity, the carrying amounts of cash and cash equivalents, short-term investments and accounts receivable approximate their fair values. The Company’s revolving and term loan debt facilities' fair values approximate book value at March 29, 2025 and December 28, 2024, as the rates on these borrowings are variable in nature. The purchase price of business acquisitions is primarily allocated to the tangible and identifiable intangible assets acquired and liabilities assumed based on their estimated fair values on the acquisition date, with the excess recorded as goodwill. The Company utilizes Level 3 inputs in the determination of the initial fair value.

The carrying value and estimated fair values of the Company’s Euro Senior Notes, Series B and USD Senior Notes, Series A and Series B, as of March 29, 2025 and December 28, 2024 were as follows:

10. Benefit Plans

The Company has Company-sponsored and mandatory defined benefit pension plans covering employees in the United Kingdom ("U.K."), Germany, the Philippines, China, Japan, Mexico, Italy and France. The amount of the retirement benefits provided under the plans is generally based on years of service and final average pay.

The Company recognizes interest cost, expected return on plan assets, and amortization of prior service, net within Other income, net in the Condensed Consolidated Statements of Net Income. The components of net periodic benefit cost for the three months ended March 29, 2025 and March 30, 2024 were as follows:


	For the Three Months Ended
(in thousands)	March 29, 2025		March 30, 2024
Components of net periodic benefit cost:
Service cost	$	727	$	795
Interest cost	954		995
Expected return on plan assets	(459)		(518)
Amortization of prior service and net actuarial loss	69		46
Net periodic benefit cost	$	1,291	$	1,318

The Company expects to make approximately $1.2 million of contributions to the plans and pay $2.1 million of benefits directly in 2025.

On October 4, 2024, the Company entered into a definitive agreement to purchase a group annuity contract, under which an insurance company is required to pay pension payments to the Company’s United Kingdom pension plan to match required pension payments until a later buyout, at which point the insurance company will directly pay and administer the benefits to the plan's participants, or to their designated beneficiaries. The purchase of this group annuity contract will reduce the Company’s outstanding pension benefit obligation by approximately $23 million, representing approximately 33% of the total obligations of the Company’s qualified pension plans, and will be funded with pension plan assets and additional cash on hand. In connection with this transaction, the Company currently expects to record a one-time non-cash settlement charge in 2026 estimated between $6 million and $8 million, reflecting the accelerated recognition of a portion of unamortized actuarial losses in the plan. The actual settlement charge could differ from this estimate due to final data and plan wind-up expenses.

The Company also sponsors certain post-employment plans in foreign countries and other statutory benefit plans. The Company recorded expense of $0.7 million for both of the three months ended March 29, 2025 and March 30, 2024, respectively, in Cost of sales and Other income, net within the Condensed Consolidated Statements of Net Income. The pre-tax losses amount recognized in other comprehensive income (loss) for these plans were $0.4 million and $0.3 million for the three months ended March 29, 2025 and March 30, 2024, respectively.

12. Income Taxes

The effective tax rate for the three months ended March 29, 2025 was 27.3%, compared to the effective tax rate for the three months ended March 30, 2024 of 13.0%. The effective tax rate for 2025 is higher than the effective tax rate for the comparable 2024 period primarily due to the lapse in the statute of limitations for previously unrecognized tax benefits in the first fiscal quarter of 2024 which favorably impacted the 2024 effective tax rate by 10.6%.

Table of Contents

The effective tax rate for 2025 is higher than the statutory tax rate primarily due to losses in non-US jurisdictions with no related tax benefit, and the effective tax rate for 2024 is lower than the statutory tax rate primarily due to the lapse in statute of limitations for previously unrecognized tax benefits.

13. Earnings Per Share

14. 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 aggregated its operating segments into the reportable 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 and as such, segment asset information is not disclosed. The CODM’s key decisions involve the allocation of resources, such as acquisitions, divestitures, investments, capital expenditures, significant customer contracts, and other key management resources, and assessment of performance, such as executive officer hiring, promotion, and compensation. The CODM uses operating income as the key metric when establishing targets in the annual budget and in evaluating the allocation of resources to each segment. The CODM regularly reviews each segment's operating income against the forecast, budget and previous quarterly results to assess performance and make decisions about the allocation of operating and capital resources to each segment.

Sales, marketing, and research and development expenses are charged directly into each operating segment. Finance, information technology, and human resources are shared functions that are allocated back to the operating segments. The Company does not report inter-segment revenue because the operating segments do not record it. Certain expenses, determined

Table of Contents

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. 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 vehicles, 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 engines, 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 circuit protection (industrial fuses), protective and monitoring relays (protection relays, residual current devices and monitors, ground fault circuit interrupters, solid state switches, and arc fault detection devices), and industrial controls and sensors (contactors, transformers, and temperature sensors) for use in various applications such as renewable energy and energy storage systems, industrial safety, factory automation, electric vehicle charging infrastructure, HVAC systems, non-residential construction, MRO, and mining.

15. Commitments and Contingencies

Off-Balance Sheet Arrangements

As of March 29, 2025, 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

The Company's 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, customers may make claims for costs they incurred or other damages related to a claim.

The Company carries insurance for potential product liability claims at coverage levels based on the Company's prior claims experience. This coverage is subject to deductibles and various terms and conditions. The Company cannot assure that the level of coverage will be sufficient to cover every possible claim that can arise in its businesses, now or in the future, or that such coverage always will be available should the Company, now or in the future, wish to extend, increase or otherwise adjust its insurance.

The Company has been notified by one of its customers of a product recall potentially due to certain fuses provided by Littelfuse and incorporated in such products. The Company is currently working with its customer to investigate the cause and level of responsibility for this recall. The Company has determined pursuant to ASC 450, "Contingencies", that a loss is reasonably possible. However, the Company continues to evaluate this matter and the ultimate costs of the recall and range of the potential loss cannot be determined at this time. Accordingly, no accrual has been made yet for this matter. Factors that will impact the amount of such losses include the per vehicle cost of fuse replacement, the determination of the relative liability among the customer, the Company, and any relevant third parties, as well as actual insurance recoveries.

Environmental Remediation Liabilities

The Company's operations and facilities are subject to U.S. and non-U.S. laws and regulations governing the protection of the environment and its 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. The Company 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 non-compliance with the environmental permits required at its facilities. Potentially significant expenditures could be required in order to comply with environmental laws that may be adopted or imposed in the future. The Company is, however, not aware of any threatened or pending material environmental investigations, lawsuits, or claims involving the Company or its operations.

Legal Proceedings

Table of Contents

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 the Company's experience and current information known, the Company does not expect the outcome of these matters, either individually or in the aggregate, to have a material adverse effect on its results of operations, financial position, and/or cash flows.

The Company accounts for litigation and claims losses in accordance with ASC 450, "Contingencies" where loss contingency provisions are recognized for probable and estimable losses at the Company's best estimate of a loss or, when a best estimate cannot be made, at its estimate of the minimum loss. These estimates require the application of considerable judgment and are refined each accounting period as additional information becomes known. If the Company is initially unable to develop a best estimate of loss, 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 when events result in an expectation different than previously expected.

Pending Litigation and Claims

There were no material pending litigation or claims outstanding as of March 29, 2025.

16. Related Party Transactions

The Company has equity ownership in various investments that are accounted for under the equity method. The following is a description of the investments and related party transactions.

Executive 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 16,000 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.

The Company maintains a network of global laboratories and engineering centers that develop new products and product enhancements, provide customer application support and test products for safety, reliability, and regulatory compliance. The Company conducts its business through three reportable segments: Electronics, Transportation, and Industrial. Within these segments, the Company designs, manufactures and sells components and modules empowering a sustainable, connected, and safer world. Our products protect against electrostatic discharge, power surges, short circuits, voltage spikes and other harmful occurrences, safely and efficiently control power and improve productivity and are used to identify and detect temperature, proximity, flow speed and fluid level in various applications.

Executive Summary

For the first quarter of 2025, the Company recognized net sales of $554.3 million, an increase of $18.9 million, or 3.5% as compared to $535.4 million in the first quarter of 2024 including $10.2 million or 1.9% of incremental net sales from the Dortmund Fab acquisition (defined below) in the semiconductor business within the Electronics segment and $6.6 million or 1.2% of unfavorable changes in foreign exchange rates. The remaining increase in net sales was primarily due to higher volume in the Industrial and Electronics segments. The Company recognized net income of $43.6 million, or $1.75 per diluted share, in the first quarter of 2025 compared to $48.5 million, or $1.93 per diluted share, in the first quarter of 2024. The decrease in net income was primarily due to the higher effective tax rate and foreign exchange losses, which were partially offset by the higher operating income in the Electronics and Industrial segments driven by increases in net sales.

Net cash provided by operating activities was $65.8 million for the three months ended March 29, 2025 compared to $57.2 million for the three months ended March 30, 2024. The increase in net cash provided by operating activities was primarily due to reductions in working capital and higher cash earnings.

Other Risk

The Company has been notified by one of its customers of a product recall potentially due to certain fuses provided by Littelfuse and incorporated in such products. The Company is currently working with its customer to investigate the cause and level of responsibility for this recall. The Company has determined pursuant to ASC 450, "Contingencies" that a loss is reasonably possible. However, the Company continues to evaluate this matter and the ultimate costs of the recall and range of the potential loss cannot be determined at this time. Accordingly, no accrual has been made yet for this matter. Factors that will impact the amount of such losses include the per vehicle cost of fuse replacement, the determination of the relative liability among the customer, the Company, and any relevant third parties, as well as actual insurance recoveries.

Recently, the U.S. government has imposed extensive tariffs on goods imported from several countries, including, without limitation, China, Mexico and Canada, as well as certain broad, product-specific tariffs on foreign goods and products. Tariffs may increase the cost of materials in our supply chain, incur reciprocal levies on components and finished products exported to or imported from affected countries, and have an adverse impact on our cost of goods sold in the U.S. and abroad. These factors 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.

Tariffs have resulted in China and other countries imposing reciprocal tariffs on U.S. goods and ceasing sales of certain products to the U.S. and could result in more U.S. trading partners adopting responsive trade policies, including making it more difficult or costly for us to export our products to those countries. Sales to customers outside of the U.S., and to China in particular, comprise a significant portion of our net sales, and reciprocal tariffs may impact our business in China. Further, tariffs and trade policies may continue to change quickly and without warning, and we may not be able to accurately anticipate and mitigate the impacts.

Net Sales

Net sales increased $18.9 million, or 3.5%, for the first quarter of 2025 compared to the first quarter of 2024 including $10.2 million or 1.9% of incremental net sales from the Dortmund Fab acquisition in the semiconductor business within the Electronics segment and $6.6 million or 1.2% of unfavorable changes in foreign exchange rates. The remaining increase in net sales was primarily due to higher volume of $15.7 million in the electronics products business within the Electronics segment and $11.3 million in the Industrial segment due to higher end market demand, partially offset by the lower volume from the remaining semiconductor business within the Electronics segment.

Cost of Sales

Cost of sales was $347.1 million, or 62.6% of net sales, in the first quarter of 2025, compared to $347.6 million, or 64.9% of net sales, in the first quarter of 2024. As a percent of net sales, cost of sales decreased 2.3% primarily driven by improved margins from the electronics products business within the Electronics segment and the industrial circuit protection business within the Industrial segment driven by volume leverage, favorable price, product mix and cost reduction initiatives.

Gross Profit

Gross profit was $207.3 million, or 37.4% of net sales, in the first quarter of 2025 compared to $187.8 million, or 35.1% of net sales, for the first quarter of 2024. The $19.4 million increase in gross profit was primarily due to higher volume and favorable price from the electronics products business within the Electronics segment and across all businesses within the Industrial segment.

Operating Expenses

Operating expenses were $137.1 million, or 24.7% of net sales, for the first quarter of 2025 compared to $132.9 million, or 24.8% of net sales, for the first quarter of 2024. The increase in operating expenses of $4.3 million was primarily due to higher restructuring, impairment, and other charges of $5.8 million related to company-wide cost control initiatives.

Operating Income

Table of Contents

Operating income was $70.2 million, representing an increase of $15.2 million, or 27.7%, for the first quarter of 2025 compared to $55.0 million for the first quarter of 2024. The increase in operating income was due to higher gross profit from the Electronics and Industrial segments, partially offset by higher operating expenses mainly driven by higher restructuring, impairment, and other charges. Operating margins increased from 10.3% in the first quarter of 2024 to 12.7% in the first quarter of 2025 driven by improved gross margin in the Electronics and Industrial segments.

Income Before Income Taxes

Income before income taxes was $59.9 million, or 10.8% of net sales, for the first quarter of 2025 compared to $55.7 million, or 10.4% of net sales, for the first fiscal quarter of 2024. In addition to the factors impacting comparative results for operating income discussed above, income before income taxes was primarily impacted by foreign exchange losses of $4.8 million in the first quarter of 2025 compared to foreign exchange gains of $5.0 million in the first quarter of 2024, and higher unrealized losses of $1.3 million related to the Company's equity investment.

Income Taxes

The effective tax rate for the three months ended March 29, 2025 was 27.3%, compared to the effective tax rate for the three months ended March 30, 2024 of 13.0%. The effective tax rate for 2025 was higher than the effective tax rate for the comparable 2024 period primarily due to the lapse in the statute of limitations for previously unrecognized tax benefits in the first quarter of 2024 which favorably impacted the 2024 effective tax rate by 10.6%.

The effective tax rate for 2025 is higher than the statutory tax rate primarily due to losses in non-US jurisdictions with no related tax benefit, and the effective tax rate for 2024 was lower than the statutory tax rate primarily due to the lapse in statute of limitations for previously unrecognized tax benefits.

ITEM 4. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

Disclosure controls and procedures (as defined in Rules 13a-15(b) and 15d-15(e) under the Exchange Act) are designed to ensure that information required to be disclosed in reports filed or submitted under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in the SEC rules and forms, and that such information is accumulated and communicated to management, including the Company's Chief Executive Officer and Chief Financial Officer, to allow timely decisions regarding required disclosures.

In connection with the preparation of this report, management, under the supervision and with the participation of the Chief Executive Officer and Chief Financial Officer, conducted an evaluation of the effectiveness of the design and operation of the Company's disclosure controls and procedures as of March 29, 2025. Based on that evaluation, the Company's Chief Executive Officer and Chief Financial Officer have concluded that, as of the quarter ended March 29, 2025, the Company's disclosure controls and procedures were not effective, because of the previously reported material weaknesses in internal control over financial reporting, as described below.

Previously Reported Material Weaknesses in Internal Control over Financial Reporting

Management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Exchange Act Rule 13a-15(f) and 15d-15(f) based on the criteria established in Internal Control-Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (“the COSO Framework). As reported in our Form 10-K for the fiscal year ended December 28, 2024, we did not maintain effective internal control over financial reporting as of December 28, 2024 as a result of material weaknesses in the control environment and control activities areas. A material weakness (as defined in Rule 12b-2 under the Exchange Act) is a deficiency, or combination of deficiencies, in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of our annual or interim financial statements will not be prevented or detected on a timely basis. Refer to our 2024 Form 10-K for a description of our material weaknesses.

Ongoing Remediation Efforts to Address Material Weaknesses

Our material weaknesses were not remediated as of March 29, 2025. Our management team is committed to maintaining a strong internal control environment. The Company, with oversight from our Audit Committee of the Board of Directors, is taking comprehensive actions to remediate the material weaknesses. The Company has developed and is in the process of implementing its remediation plan, which will include the following steps:

Control environment

•recruiting of personnel with appropriate internal controls, and accounting knowledge and experience commensurate with our accounting and reporting requirements;

•enhanced supervision of personnel at certain locations to ensure compliance with established Company policies; and

•evaluating and updating (as appropriate) the sufficiency of policies and training provided to personnel to ensure the appropriate segregation of duties and adherence to the Code of Conduct.

Control activities

•augmentation of training and clear instruction as to the process for recording of adjustments to inventories;

•full physical inventory observations, facilitated by independent counters, until the cycle count and related inventory existence controls at certain of our non-U.S. manufacturing locations are operating effectively;

•implementation of a management review control over inventory movements;

•examination and enhancement of the procedures to evaluate the completeness and accuracy of data and assumptions utilized in computing inventory reserves.

We intend to remediate the material weaknesses as soon as possible; however, the material weaknesses will not be considered remediated until the applicable controls operate for a sufficient period of time and management has concluded, through testing, that the appropriate controls are operating effectively.

Changes in Internal Control over Financial Reporting

Other than the ongoing remediation efforts described above, there were no changes in the Company's internal control over financial reporting identified in connection with the evaluation required by Rules 13a-15(f) and 15d-15(f) under the Exchange

ITEM 1A. RISK FACTORS

Changes in U.S. and other countries trade policy, including the imposition of tariffs and the resulting consequences and uncertainties, may have a material adverse impact on our business and results of operations.

Our international presence subjects us to risks associated with international trade conflicts between the United States and its trade partners, particularly with regard to the risk of heightened tariffs and import/export controls. Recently, the U.S. government has imposed extensive tariffs on several countries, including, without limitation, China, Mexico and Canada, as well as certain broad, product-specific tariffs on foreign goods and products. Tariffs may increase the cost of materials in our supply chain, incur reciprocal levies on components and finished products exported to or imported from affected countries, and have an adverse impact on our cost of goods sold in the U.S. and abroad. These factors 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. Additionally, the adoption or threat of adoption of extensive tariffs could result in an economic slowdown, a significant reduction in consumer confidence, and an increased risk of inflationary pressure, all of which, either separately or together, could adversely affect our business.

Tariffs have resulted in China and other countries imposing reciprocal tariffs on U.S. goods and ceasing sales of certain products to the U.S. and could result in more U.S. trading partners adopting responsive trade policies, including making it more difficult or costly for us to export our products to those countries. Sales to customers outside of the U.S., and to China in particular, comprise a significant portion of our net sales, and reciprocal tariffs may impact our business in China. Continued geopolitical issues and barriers to trade may result in customers outside the U.S. seeking to source products from local suppliers, which could further result in lower sales or lost customers. Further, tariffs and trade policies may continue to change quickly and without warning, and we may not be able to accurately anticipate and mitigate the impacts.

Other than the item listed above, there have been no material changes in our risk factors from those disclosed in our Annual Report on Form 10-K for our year ended December 28, 2024.
