Basis of Presentation 

The Company’s accompanying unaudited Condensed Consolidated Financial Statements have been prepared in accordance with U.S. Generally Accepted Accounting Principles (“GAAP”) for interim financial information, the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, certain information and disclosures normally included in the consolidated balance sheets, statements of net income and comprehensive income, statements of cash flows, and statements of stockholders' equity prepared in conformity with U.S. GAAP have been condensed or omitted as permitted by such rules and regulations, although the Company believes that the disclosures made are adequate to make the information not misleading.

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 distribution channels are primarily through direct sales and independent third-party distributors.

The Company 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 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

Table of Contents

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 Littelfuse 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.

Recently Issued Accounting Standards

In March 2023, the Financial Accounting Standards Board ("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 on January 1, 2024. The Company does not expect any material effect on the Company's Condensed 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.

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,

Table of Contents

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, on a preliminary basis, to assets acquired and liabilities assumed, as of the completion of the acquisition, based on preliminary estimated fair values. The purchase price allocation is preliminary because the evaluations necessary to assess the fair values of the net assets acquired are still in process. The primary area not yet finalized relates to the completion of the valuation of certain acquired income tax assets and liabilities. As a result, these allocations are subject to change during the purchase price allocation period as the valuations are finalized.

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

(in thousands)	Purchase Price Allocation
Total purchase consideration:
Cash, net of cash acquired	$	158,260
Allocation of consideration to assets acquired and liabilities assumed:
Trade receivables, net	3,389
Inventories	3,678
Other current assets	718
Property, plant, and equipment	1,328
Intangible assets	68,000
Goodwill	94,823
Other non-current assets	573
Current liabilities	(5,251)
Other non-current liabilities	(8,998)
	$	158,260

All Western Automation assets and liabilities were recorded in the Industrial 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 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.

Included in the Company’s Condensed Consolidated Statements of Net Income for the three and six months ended July 1, 2023 are net sales of approximately $4.8 million and $7.5 million respectively, and an income before income taxes of $0.3 million and $0.2 million, respectively, since the February 3, 2023 acquisition of Western Automation.

During the six months ended July 1, 2023, the Company incurred approximately $1.4 million of legal and professional fees related to the Western Automation acquisition recognized as Selling, general, and administrative expenses. These costs were reflected as other non-segment costs.

C&K Switches

On July 19, 2022, the Company completed the previously announced acquisition of 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. At the time the Company and C&K entered into the definitive agreement, C&K had annualized sales of over $200 million. The business is reported as part of the electronics-passive products and sensors business within the Company's Electronics segment.

The acquisition was funded through a combination of cash on hand and debt. The total purchase consideration of $523.0 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 preliminary estimated fair values. 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 area not

yet finalized relates to the completion of the valuation of certain acquired income tax assets and liabilities. As a result, these allocations are subject to change during the purchase price allocation period as the valuations are finalized.

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

(in thousands)	Purchase Price Allocation
Total purchase consideration:
Cash, net of cash acquired	$	523,014
Allocation of consideration to assets acquired and liabilities assumed:
Trade receivables, net	20,967
Inventories	42,968
Other current assets	2,932
Property, plant, and equipment	32,791
Intangible assets	254,700
Goodwill	274,124
Other non-current assets	14,797
Current liabilities	(47,687)
Long-term debt	(9,626)
Other non-current liabilities	(62,952)
	$	523,014

All C&K goodwill, other assets and liabilities were recorded in the Electronics segment and are reflected in the Americas, Europe and Asia-Pacific geographic areas. The goodwill resulting from this acquisition consists largely of the Company’s expected future product sales and synergies from combining 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.

During the three months ended July 1, 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 based on the preliminary valuation. 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.

Embed

On April 12, 2022, the Company acquired Embed Ltd. (“Embed”). Founded in 2005, Embed is a proven provider of embedded software and firmware developed for a broad range of applications serving transportation end markets, primarily including commercial vehicle electrification and eMobility. The business is included in the commercial vehicle business within the Company's Transportation segment. The acquisition was funded with the Company’s cash on hand. The total purchase consideration was $9.2 million, net of cash.

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 business acquired on November 30, 2021 as though the acquisition 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 the C&K acquisition occurred as of December 27, 2020 and had Carling acquisition occurred as of December 29, 2019 or of future consolidated operating results.

Revolving Credit Facility and Term Loan

On June 30, 2022, the Company amended and restated its Credit Agreement, dated as of April 3, 2020 (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 —% 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 three and six months ended July 1, 2023, the Company made payments of $1.9 million and $3.8 million on its term loan, respectively. The revolving loan and term loan balance under the Credit Facility was $100.0 million and $292.5 million, respectively, as of July 1, 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 July 1, 2023, the effective interest rate on revolving loan and term loan outstanding borrowings was 6.45%.

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 and 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, which are held with an institution with sound credit rating and are highly liquid. The Company classified cash equivalents as Level 1 and are valued at cost which approximates fair value.

Investments in Equity Securities

Investments in equity securities listed on a national market or exchange are valued at the last sales price and classified within Level 1 of the valuation hierarchy and recorded in Investments and Other long-term assets.

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 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 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 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 1, 2023 was €117.0 million and expires on December 7, 2023. The foreign currency contract was not designated as a hedge instrument and is marked to market on a monthly basis. As a result, changes in fair value are reported in Foreign exchange (gain) loss in the Condensed Consolidated Statements of Operations. The fair value of the foreign currency forward contract was valued using market exchange rates by a third party and classified as a Level 2 input under the fair value hierarchy.

As of July 1, 2023 and December 31, 2022, the fair values of our derivative financial instrument and their classifications on the Condensed Consolidated Balance Sheets were as follows:

The pre-tax gain of $4.8 million from accumulated other comprehensive loss to earnings is expected to be recognized during the next twelve months.

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.

There were no changes during the quarter ended July 1, 2023 to the Company’s valuation techniques used to measure asset and liability fair values on a recurring basis. As of July 1, 2023 and December 31, 2022, 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 July 1, 2023 and December 31, 2022, as the rates on these borrowings are variable in nature.

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 July 1, 2023 and December 31, 2022 were as follows:

12. Income Taxes

The effective tax rate for the three and six months ended July 1, 2023 was 18.0% and 18.3%, respectively, compared to the effective tax rate for the three and six months ended July 2, 2022 of 20.6% and 16.1%, respectively. The effective tax rate for the second quarter of 2023 is lower than the effective tax rate for the comparable 2022 period, primarily due to the impact of foreign exchange losses with no related tax benefit in the 2022 period.

The effective tax rate for the first six months of 2023 is higher than the effective tax rate for the comparable 2022 period, primarily due to the impact of a one-time deduction in the first quarter of 2022 that resulted in a net benefit of $7.2 million from the dissolution of one of the Company’s affiliates. The effective tax rates for both periods were lower than the applicable U.S. statutory tax rate primarily due to income earned in lower tax jurisdictions, while for the 2022 period, the effective tax rate was also lower due to the impact of the one-time deduction previously noted.

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.

Executive Summary

For the second quarter of 2023, the Company recognized net sales of $612.0 million, a decrease of $6.4 million, or 1.0% as compared to $618.4 million in the second quarter of 2022 including $0.5 million or 0.1% of unfavorable changes in foreign exchange rates. The decrease in net sales was due to lower volume in the Electronics segment and the commercial vehicle business within the Transportation segment that more than offset $40.0 million or 6.5% and $4.8 million or 0.8% of incremental net sales from the C&K and Western Automation acquisitions, respectively, and higher volume in the Industrial segment. The Company recognized net income of $70.1 million, or $2.79 per diluted share, in the second quarter of 2023 compared to $87.0 million, or $3.48 per diluted share in the second quarter of 2022. The decrease in net income was primarily due to a decrease in operating income in the Electronics and Transportation segments driven by lower volume.

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 approximately 37 million Euro will be paid after regulatory approvals and approximately 56 million Euro will be paid at closing. The transaction is not expected to have a material impact on the Company’s fiscal year 2023 or 2024 financial results and will be reported in the Electronics-Semiconductor business within the Company’s Electronics segment.

On February 3, 2023, the Company acquired 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. Western Automation has annualized sales of approximately $25 million and will be reported within the company’s Industrial segment. The company does not expect the acquisition to have a material impact to its 2023 financial results. The Company financed the transaction with cash on hand.

Net cash provided by operating activities was $151.6 million for the six months ended July 1, 2023 compared to $165.3 million for the six months ended July 2, 2022. The decrease in net cash provided by operating activities was primarily due to lower cash earnings, partially offset by reductions in working capital.

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 modest 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.

The increase in net sales was primarily due to incremental sales from the acquisition of C&K, increased volume from the semiconductor business within the Electronics segment and the passenger car products business within the Transportation segment, and incremental sales from the Western Automation acquisition included within the Industrial segment compared to the second quarter of 2022.

Net sales increased $58.4 million, or 23.9%, in the first six months of 2023 compared to the first six months of 2022 and included unfavorable changes in foreign exchange rates of $3.4 million. The increase in net sales was primarily due to incremental sales from the acquisition of C&K, increased volume from the semiconductor business within the Electronics

segment, and incremental sales from the Western Automation acquisition included within the Industrial segment compared to the first six months of 2022, partially offset by lower net sales from the Electronics products business within the Electronics segment.

Liquidity and Capital Resources 

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.

Cash and cash equivalents were $480.7 million as of July 1, 2023, a decrease of $81.8 million as compared to December 31, 2022. As of July 1, 2023, $127.4 million of the Company's $480.7 million cash and cash equivalents was held by U.S. subsidiaries.

Revolving Credit Facility and Term Loan

On June 30, 2022, the Company amended and restated its Credit Agreement, dated as of April 3, 2020 (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. 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 three and six months ended July 1, 2023, the Company made payments of $1.9 million and $3.8 million on its term loan, respectively. The revolving loan and term loan balance under the Credit Facility was $100.0 million and $292.5 million, respectively, as of July 1, 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 July 1, 2023, the effective interest rate on revolving loan and term loan outstanding borrowings was 6.45%.

As of July 1, 2023, the Company had $0.2 million outstanding letters of credit under the Credit Facility and had $599.8 million of borrowing capacity available under the revolving Credit Facility. As of July 1, 2023, the Company was in compliance with all covenants under the Credit Agreement.

See Note 15, Segment Information for net sales by segment and countries.

Revenue Recognition

The Company recognizes revenue on product sales in the period in which the Company satisfies its performance obligation and control of the product is transferred to the customer. The Company’s sales arrangements with customers are predominately short term in nature and generally provide for transfer of control at the time of shipment as this is the point at which title and risk of loss of the product transfers to the customer. At the end of each period, for those shipments where title to the products and the risk of loss and rewards of ownership do not transfer until the product has been received by the customer, the Company adjusts revenues and cost of sales for the delay between the time that the products are shipped and when they are received by the customer. The amount of revenue recorded reflects the consideration to which the Company expects to be entitled in exchange for goods and may include adjustments for customer allowance, rebates and price adjustments. The Company’s distribution channels are primarily through direct sales and independent third-party distributors.

The Company 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 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 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 Littelfuse 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 July 1, 2023 and December 31, 2022 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.

(in thousands)	July 1, 2023		December 31, 2022
Cash and cash equivalents	$	480,743	$	562,588
Restricted cash included in prepaid expenses and other current assets	771		802
Restricted cash included in other long-term assets	1,580		1,549
Total cash, cash equivalents, and restricted cash	$	483,094	$	564,939

Recently Issued Accounting Standards

In March 2023, the Financial Accounting Standards Board ("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 on January 1, 2024. The Company does not expect any material effect on the Company's Condensed Consolidated Financial Statements.

Business Combination and Asset Acquisition [Abstract]

Acquisitions

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.

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, on a preliminary basis, to assets acquired and liabilities assumed, as of the completion of the acquisition, based on preliminary estimated fair values. The purchase price allocation is preliminary because the evaluations necessary to assess the fair values of the net assets acquired are still in process. The primary area not yet finalized relates to the completion of the valuation of certain acquired income tax assets and liabilities. As a result, these allocations are subject to change during the purchase price allocation period as the valuations are finalized.

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

(in thousands)	Purchase Price Allocation
Total purchase consideration:
Cash, net of cash acquired	$	158,260
Allocation of consideration to assets acquired and liabilities assumed:
Trade receivables, net	3,389
Inventories	3,678
Other current assets	718
Property, plant, and equipment	1,328
Intangible assets	68,000
Goodwill	94,823
Other non-current assets	573
Current liabilities	(5,251)
Other non-current liabilities	(8,998)
	$	158,260

All Western Automation assets and liabilities were recorded in the Industrial 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 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.

Included in the Company’s Condensed Consolidated Statements of Net Income for the three and six months ended July 1, 2023 are net sales of approximately $4.8 million and $7.5 million respectively, and an income before income taxes of $0.3 million and $0.2 million, respectively, since the February 3, 2023 acquisition of Western Automation.

During the six months ended July 1, 2023, the Company incurred approximately $1.4 million of legal and professional fees related to the Western Automation acquisition recognized as Selling, general, and administrative expenses. These costs were reflected as other non-segment costs.

C&K Switches

On July 19, 2022, the Company completed the previously announced acquisition of 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. At the time the Company and C&K entered into the definitive agreement, C&K had annualized sales of over $200 million. The business is reported as part of the electronics-passive products and sensors business within the Company's Electronics segment.

The acquisition was funded through a combination of cash on hand and debt. The total purchase consideration of $523.0 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 preliminary estimated fair values. 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 area not

yet finalized relates to the completion of the valuation of certain acquired income tax assets and liabilities. As a result, these allocations are subject to change during the purchase price allocation period as the valuations are finalized.

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

(in thousands)	Purchase Price Allocation
Total purchase consideration:
Cash, net of cash acquired	$	523,014
Allocation of consideration to assets acquired and liabilities assumed:
Trade receivables, net	20,967
Inventories	42,968
Other current assets	2,932
Property, plant, and equipment	32,791
Intangible assets	254,700
Goodwill	274,124
Other non-current assets	14,797
Current liabilities	(47,687)
Long-term debt	(9,626)
Other non-current liabilities	(62,952)
	$	523,014

All C&K goodwill, other assets and liabilities were recorded in the Electronics segment and are reflected in the Americas, Europe and Asia-Pacific geographic areas. The goodwill resulting from this acquisition consists largely of the Company’s expected future product sales and synergies from combining 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.

During the three months ended July 1, 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 based on the preliminary valuation. 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.

Embed

On April 12, 2022, the Company acquired Embed Ltd. (“Embed”). Founded in 2005, Embed is a proven provider of embedded software and firmware developed for a broad range of applications serving transportation end markets, primarily including commercial vehicle electrification and eMobility. The business is included in the commercial vehicle business within the Company's Transportation segment. The acquisition was funded with the Company’s cash on hand. The total purchase consideration was $9.2 million, net of cash.

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 business acquired on November 30, 2021 as though the acquisition 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 the C&K acquisition occurred as of December 27, 2020 and had Carling acquisition occurred as of December 29, 2019 or of future consolidated operating results.

Revolving Credit Facility and Term Loan

On June 30, 2022, the Company amended and restated its Credit Agreement, dated as of April 3, 2020 (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 —% 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 three and six months ended July 1, 2023, the Company made payments of $1.9 million and $3.8 million on its term loan, respectively. The revolving loan and term loan balance under the Credit Facility was $100.0 million and $292.5 million, respectively, as of July 1, 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 July 1, 2023, the effective interest rate on revolving loan and term loan outstanding borrowings was 6.45%.

As of July 1, 2023, the Company had $0.2 million outstanding letters of credit under the Credit Facility and had $599.8 million of borrowing capacity available under the revolving Credit Facility. As of July 1, 2023, the Company was in compliance with all covenants under the Credit Agreement.

Fair Value of Assets and Liabilities

6 Months Ended

Jul. 01, 2023

Fair Value Disclosures [Abstract]

Fair Value of Assets and Liabilities

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 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, which are held with an institution with sound credit rating and are highly liquid. The Company classified cash equivalents as Level 1 and are valued at cost which approximates fair value.

Investments in Equity Securities

Investments in equity securities listed on a national market or exchange are valued at the last sales price and classified within Level 1 of the valuation hierarchy and recorded in Investments and Other long-term assets.

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 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 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 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 1, 2023 was €117.0 million and expires on December 7, 2023. The foreign currency contract was not designated as a hedge instrument and is marked to market on a monthly basis. As a result, changes in fair value are reported in Foreign exchange (gain) loss in the Condensed Consolidated Statements of Operations. The fair value of the foreign currency forward contract was valued using market exchange rates by a third party and classified as a Level 2 input under the fair value hierarchy.

As of July 1, 2023 and December 31, 2022, the fair values of our derivative financial instrument and their classifications on the Condensed Consolidated Balance Sheets were as follows:

The pre-tax gain of $4.8 million from accumulated other comprehensive loss to earnings is expected to be recognized during the next twelve months.

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.

There were no changes during the quarter ended July 1, 2023 to the Company’s valuation techniques used to measure asset and liability fair values on a recurring basis. As of July 1, 2023 and December 31, 2022, the Company did not hold any non-financial assets or liabilities that are required to be measured at fair value on a recurring basis.

The following table presents assets measured at fair value by classification within the fair value hierarchy as of July 1, 2023:

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 July 1, 2023 and December 31, 2022, as the rates on these borrowings are variable in nature.

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 July 1, 2023 and December 31, 2022 were as follows:

Income Taxes

Income Taxes

The effective tax rate for the three and six months ended July 1, 2023 was 18.0% and 18.3%, respectively, compared to the effective tax rate for the three and six months ended July 2, 2022 of 20.6% and 16.1%, respectively. The effective tax rate for the second quarter of 2023 is lower than the effective tax rate for the comparable 2022 period, primarily due to the impact of foreign exchange losses with no related tax benefit in the 2022 period.

The effective tax rate for the first six months of 2023 is higher than the effective tax rate for the comparable 2022 period, primarily due to the impact of a one-time deduction in the first quarter of 2022 that resulted in a net benefit of $7.2 million from the dissolution of one of the Company’s affiliates. The effective tax rates for both periods were lower than the applicable U.S. statutory tax rate primarily due to income earned in lower tax jurisdictions, while for the 2022 period, the effective tax rate was also lower due to the impact of the one-time deduction previously noted.

Segment Reporting [Abstract]

Segment Information

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 circuit protection (industrial fuses), 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.

Accounting Policies [Abstract]

Basis of Presentation

Basis of Presentation 

The Company’s accompanying unaudited Condensed Consolidated Financial Statements have been prepared in accordance with U.S. Generally Accepted Accounting Principles (“GAAP”) for interim financial information, the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, certain information and disclosures normally included in the consolidated balance sheets, statements of net income and comprehensive income, statements of cash flows, and statements of stockholders' equity prepared in conformity with U.S. GAAP have been condensed or omitted as permitted by such rules and regulations, although the Company believes that the disclosures made are adequate to make the information not misleading. They have been prepared in accordance with accounting policies described in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2022, which should be read in conjunction with the disclosures therein. In the opinion of management, all adjustments considered necessary for a fair presentation have been included and are of a normal, recurring nature. Operating results for interim periods are not necessarily indicative of annual operating results.

Revenue Recognition

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 distribution channels are primarily through direct sales and independent third-party distributors.

The Company 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 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 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 Littelfuse 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.

Recently Issued Accounting Standards

In March 2023, the Financial Accounting Standards Board ("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 on January 1, 2024. The Company does not expect any material effect on the Company's Condensed Consolidated Financial Statements.
