Littelfuse, Inc. (LFUS) — ESG & Values Scores

Environment story

Littelfuse demonstrates significant environmental governance gaps. The company has disclosed neither Scope 1, Scope 2, nor Scope 3 emissions data, nor renewable energy percentages or net-zero commitments in the 10-K filing. Climate-related regulatory risks are identified as material, including potential EU CSRD/CS3D compliance obligations and California GHG disclosure requirements enacted in 2023. The company owns and operates discontinued coal mining operations in Germany requiring ongoing environmental remediation. No disclosed investments in decarbonization infrastructure, renewable energy procurement, or emissions-reduction capital projects are evident. The absence of emissions transparency and net-zero target substantially constrains the Environmental score.

Discontinued Coal Mining Operations Remediation — Germany
Source: LFUS 10-K Risk Factors: 'The Company is responsible for the maintenance of discontinued coal mining operations in Germany. The risk of environmental remediation exists, and the Company is in the process of remediating the mines considered to be the most at risk.'
Hazardous Materials Handling and Legacy Contamination Risk
Source: LFUS 10-K Risk Factors: 'In the conduct of manufacturing operations, the Company has handled and does handle materials that are considered hazardous, toxic or volatile under federal, state, and local laws. The Company operates or owns facilities located on or near real property that was formerly owned and operated by others. Certain of these properties were used in ways that involved hazardous materials.'
California GHG Disclosure Compliance Requirement (2023)
Source: LFUS 10-K Risk Factors: 'For example, California enacted legislation in 2023 requiring disclosure of certain companies' greenhouse gas (GHG) emissions, climate-related financial risks, voluntary carbon offsets (VCOs), and certain climate-related emission claims.'
EU Corporate Sustainability Reporting Directive (CSRD) and Due Diligence Directive (CS3D) Compliance Uncertainty
Source: LFUS 10-K Risk Factors: 'The European Union (EU) enacted the Corporate Sustainability Reporting Directive (CSRD) and Corporate Sustainability Due Diligence (CS3D) in 2023 and 2024, respectively, and published proposed revisions to both the CSRD and CS3D through omnibus legislation in 2025. We are further assessing our compliance and reporting strategies under CSRD and CS3D, but our obligations under these and other EU climate directives may incur substantial effort in the future.'

Disclosed initiatives

Environmental Compliance Programs

Company reports expending resources and capital on environmental compliance programs under foreign, federal, state and local laws and regulations governing discharge of materials, chemicals and gases used in manufacturing.

Social story

Littelfuse's social profile shows mixed signals. The company acknowledges labor-relations risks including potential work stoppages, collective bargaining negotiations, and international supply-chain labor disruptions. The 10-K explicitly identifies failure to attract and retain qualified personnel and senior management turnover as business risks. No disclosed data on CEO-to-median-worker pay ratio, workforce diversity metrics, executive leadership gender/racial representation, or formal diversity programs appear in the filing. The company faces product-liability and recall risks (one customer product recall investigation noted), which may impact worker safety and customer trust. Supply-chain audits for labor abuses, conflict minerals, or modern slavery compliance are not substantively disclosed, though the company notes Dodd-Frank conflict-minerals disclosure requirements and challenges verifying conflict-free metals. Union-suppression activities are not mentioned; neutral or cooperative labor-relations posture cannot be confirmed.

Product Recall Investigation — Customer Product Defect
Source: LFUS 10-K Risk Factors: 'The Company has been notified by one of its customers of a product recall potentially due to certain fuses provided by the Company and incorporated in the customer's products. The Company is working with its customer to investigate the cause and level of responsibility for this recall.'
Labor Dispute and Work-Stoppage Risk
Source: LFUS 10-K Risk Factors: 'The Company's business may be interrupted by labor disputes or other interruptions of supplies. A work stoppage could occur at certain Company facilities, most likely as a result of disputes under collective bargaining agreements or in connection with negotiations of new collective bargaining agreements.'
Senior Management Turnover and Retention Risk
Source: LFUS 10-K Risk Factors: 'We have had, and could have additional, changes in senior management, which could be disruptive to the Company's operations and may have an adverse effect on our business, financial condition and results of operations.'
International Supply-Chain Labor Disruptions
Source: LFUS 10-K Risk Factors: 'Further, our reliance on international supply chain systems exposes us to potential interruptions and delays cause by transportation labor shortages, including dock worker stoppages and freight carrier disruptions.'
Conflict Minerals Sourcing Challenge
Source: LFUS 10-K Risk Factors: 'As there may be only a limited number of suppliers offering "conflict free" metals, the Company cannot be certain that it will be able to obtain necessary metals in sufficient quantities or at competitive prices.'

Disclosed initiatives

Conflict-Free Minerals Compliance Effort

Company discloses efforts to comply with Dodd-Frank Wall Street Reform and Consumer Protection Act conflict-minerals reporting requirements, identifying challenges in sourcing conflict-free metals in sufficient quantities at competitive prices.
Supply-Chain Supplier Diversity Commitment

Company references third-party supplier and contract manufacturer relationships in global networks; specific supplier diversity programs or certifications not disclosed.

Governance story

Littelfuse's governance structure exhibits material weaknesses in internal controls, mitigated somewhat by absence of dual-class share structure and limited evidence of deregulatory lobbying. The company disclosed material weaknesses in internal controls over financial reporting in 2025, which were subsequently remediated; however, integration of the Basler acquisition poses ongoing control risks. Recent goodwill impairment charges totaling $301.2 million (Semiconductor unit, 2025) and $44.7 million (Industrial Controls and Sensors, Industrial Controls and Sensors units, 2024) signal asset-valuation governance concerns and potential prior-period estimation errors. Board independence percentage, lobbying expenditure, and PAC contributions are not disclosed in the filing. No evidence of shareholder litigation over governance, dual-class voting structures, or active climate-deregulation lobbying is apparent. Antitrust or consumer-protection regulatory proceedings are not disclosed as active.

Material Weaknesses in Internal Controls (2025)
Source: LFUS 10-K: 'In 2025, the Company remediated the material weaknesses identified by management, see "Part II, Item 9A - Controls and Procedures." If the enhanced controls implemented to address the material weaknesses and to strengthen our overall internal control do not operate effectively, or if we are unsuccessful in following these enhanced processes in the future, such failures may result in delayed or inaccurate reporting of our financial results.'
Significant Goodwill Impairment Charges (2024-2025)
Source: LFUS 10-K: 'As a result of the 2025 annual goodwill impairment test, the Company recorded a non-cash charge of $301.2 million to reflect the impairment of goodwill for the Semiconductor reporting unit within the Electronics segment. As a result of the 2024 annual goodwill impairment test, the Company recorded non-cash charges of $36.1 million and $8.6 million to reflect the impairment of goodwill for the Industrial Controls and Sensors reporting unit within the Industrial segment and the Automotive Sensors reporting unit within the Transportation segment, respectively.'

Basler Acquisition Integration Control Risk
Source: LFUS 10-K: 'Management has excluded Basler's internal controls over financial reporting from its assessment of the effectiveness of internal controls over financial reporting as of December 27, 2025.
