Material Changes vs. Prior Period
- Revenue Growth: Net revenue increased 5.9% year-over-year, driven primarily by higher sales in the industrial end-market (38% of revenue in 2025 vs. 35% in 2024), including growth in gate-driver products, utility meters, EVs, and battery-powered tools.
- Margin Expansion: Gross margin improved to 54.5% from 53.6% due to manufacturing efficiencies from higher unit volumes and a favorable shift in end-market mix toward higher-margin categories.
- Operating Expense Increase: Total operating expenses rose by $24.6 million (11.9%) to $231.5 million. This was primarily due to:
- Other Operating Expenses: A new line item totaling $19.7 million, comprising $11.3 million related to an employee litigation matter and $8.4 million in stock-based compensation resulting from the modification of awards for the retiring CEO.
- G&A Expenses: Increased 11.8% due to higher professional and legal services.
- Profitability Decline: Despite revenue growth and margin expansion, Net Income declined 31.4% due to the significant one-time charges in operating expenses.
Guidance, Outlook, Risks, and Unusual Items
Management Commentary and Outlook
- Strategic Focus: Management continues to focus on increasing market penetration in existing markets and expanding the addressable market through new products, particularly leveraging proprietary Gallium-Nitride (GaN) technology for higher-power applications (e.g., AI data centers, EV drivetrains).
- Acquisition: In July 2024, the company acquired assets of Odyssey Semiconductor to accelerate high-power GaN development.
- Capital Allocation: The company exhausted its $50.0 million stock repurchase authorization in 2025 (totaling $98.1 million in repurchases for the year). Dividends were raised to $0.215 per share for 2026.
Risks and Contingencies
- Legal Proceedings:
- Employee Litigation: A jury verdict in June 2025 resulted in $9.2 million in damages plus attorney fees. The company recognized $13.3 million in total charges related to this matter in 2025 and has appealed the judgment.
- Patent Litigation: The company successfully obtained a verdict of non-infringement and invalidity against CogniPower LLC in August 2025, though appeals are pending.
- Trade and Geopolitics: Significant exposure to international sales (98% of revenue). Risks include tariffs, trade tensions between the U.S. and China, and supply chain disruptions.
- Customer Concentration: Top 10 customers accounted for 81% of revenue in 2025. Avnet alone represented 32% of revenue.
- Subsequent Event: On January 31, 2026, the company approved a reduction in force affecting approximately 7% of its global workforce, with estimated costs of $3.5 million to $4.0 million to be recognized in Q1 2026.
Investor Verification Checklist
- One-Time Charges: Verify the impact of the $19.7 million "Other operating expenses" (litigation and CEO award modification) on the true operating performance and future run-rate profitability.
- Customer Concentration: Assess the risk associated with Avnet representing nearly one-third of total revenue and the top 10 customers representing 81%.
- Legal Appeals: Monitor the status of the appeal regarding the employee litigation verdict and the CogniPower patent case for potential future financial impact.
- Restructuring Costs: Confirm the timing and magnitude of the $3.5 million to $4.0 million severance costs associated with the 7% workforce reduction announced in January 2026.
- Stock Repurchases: Note that the current repurchase authorization is exhausted; future buybacks require new board approval.
- Wafer Supply: Review the status of long-term wafer supply agreements with Lapis, Epson, and X-FAB, which are critical to production capacity.
