Business Context and Reporting Period

This report covers the quarterly period ended September 27, 2025.

Key Financial Metrics

Material Changes vs. Prior Period

• Revenue Growth: Q3 net sales increased 10.1% year-over-year, driven by a 17.5% surge in the Electronics segment (due to volume and the Dortmund Fab acquisition) and an 11.9% increase in the Industrial segment. The Transportation segment remained flat.
• Profitability: Operating margins expanded to 15.6% in Q3 2025 from 15.5% in Q3 2024. Gross margins improved due to volume leverage and favorable product mix in electronics products, partially offset by lower margins in the semiconductor business.
• Foreign Exchange: The company benefited from $7.4M in favorable foreign exchange impacts on sales in Q3, and significantly lower foreign exchange losses ($0.2M) compared to Q3 2024 ($9.6M).
• Restructuring: The company recorded $1.6M in restructuring charges in Q3 2025 (primarily employee terminations) compared to $1.8M in Q3 2024.

Guidance, Outlook, and Risks

• Acquisitions:
  • Basler Electric: On October 24, 2025, Littelfuse agreed to acquire Basler Electric Company for approximately $350 million in cash. The deal is subject to regulatory approval and will be reported in the Industrial segment.
  • Dortmund Fab: Completed in Dec 2024, this semiconductor fab contributed $12.9M in incremental sales in Q3 2025.
• Goodwill Impairment Risk: Management noted that the Electronics-Semiconductor reporting unit is at risk for future impairment if projected results are not met, citing lower-than-expected demand in the power semiconductor business. As of Q3 2025, the unit's fair value exceeded book value by approximately 82%.
• Product Recall: A customer notified the company of a potential product recall involving certain fuses. The company has determined a loss is "reasonably possible" but cannot estimate the cost; no accrual has been made.
• Trade Policy: Extensive tariffs imposed by the U.S. and reciprocal tariffs from China and other countries pose risks to supply chain costs and export demand.
• Internal Controls: The company reported that disclosure controls and procedures were not effective as of September 27, 2025, due to previously reported material weaknesses in the control environment and control activities (specifically regarding inventory management and segregation of duties). Remediation efforts are ongoing.

Investor Verification Checklist

• Internal Control Remediation: Verify the timeline and progress of remediation for the material weaknesses in inventory controls and the control environment, as these remain unremediated.
• Semiconductor Demand: Monitor the Electronics-Semiconductor segment's performance closely, as it carries a specific risk of goodwill impairment due to lower demand expectations.
• Recall Liability: Track the resolution of the fuse product recall to determine if a material loss accrual becomes necessary.
• Basler Acquisition: Confirm the closing of the $350M Basler Electric acquisition and its integration impact on the Industrial segment.
• Tariff Impact: Assess the actual financial impact of ongoing trade tariffs on cost of sales and pricing power in key markets like China and Mexico.
