Key Financial Metrics

Note: Total Liquidity for Q1 2025 is calculated as Cash ($49.6M) + Short-term Marketable Securities ($239.7M).

Material Changes vs. Prior Period

• Revenue Growth: Net revenues increased 15.1% year-over-year, driven by higher sales across all four end-market categories, with the most significant growth in the consumer sector.
• Margin Expansion: Gross margin improved by 310 basis points to 55.2%, primarily due to favorable USD/JPY exchange rates impacting wafer costs and higher manufacturing volumes reducing unit costs.
• Profitability Surge: Operating income jumped from $0.5 million to $6.7 million, and Net Income more than doubled to $8.8 million.
• Expense Increases: Total operating expenses rose to $51.5 million (from $47.3 million), driven by increased stock-based compensation ($8.7M vs $6.4M) and higher employee-related costs.
• Customer Concentration: The top ten customers accounted for 80% of net revenues in Q1 2025, up from 77% in Q1 2024. Avnet alone represented 32% of revenues.

Guidance, Outlook, Risks, and Unusual Items

• Capital Allocation: The company repurchased approximately 404,000 shares for $23.1 million during the quarter. In April 2025, the board utilized the remaining $25.0 million of the prior authorization and approved an additional $50.0 million for future repurchases. Quarterly dividends were raised to $0.21 per share.
• Strategic Acquisitions: The company closed the acquisition of Odyssey Semiconductor Technologies in July 2024 to accelerate vertical gallium-nitride (GaN) transistor development. No pro forma results were presented as the impact is not material.
• Legal Contingencies: The company is involved in patent litigation with CogniPower LLC regarding two patents. A trial is scheduled for August 2025. The company believes it has strong defenses but notes that litigation could be costly and divert management attention.
• Risk Factors: Significant risks include changes in trade policies and tariffs (particularly between the U.S. and China/APAC), which could reduce demand or pressure pricing. The company also faces risks related to supply chain dependencies on Japanese wafer suppliers and foreign exchange fluctuations.
• Tax Rate: The effective tax rate was 11.1% in Q1 2025, compared to 0.5% in Q1 2024. The increase was due to the recognition of share-based payments and foreign income subject to U.S. tax (GILTI).

Investor Verification Checklist

• Customer Concentration: Verify the stability of the top 10 customers (80% of revenue), specifically Avnet (32%), given the lack of long-term contracts.
• Trade Policy Exposure: Assess the potential impact of new U.S. tariffs and reciprocal actions announced in Q1 2025 on the company's Asia-based manufacturing supply chain and end-market demand.
• Legal Outcome: Monitor the August 2025 trial date for the CogniPower patent infringement case for potential financial or operational impacts.
• Stock-Based Compensation: Review the trend in stock-based compensation expenses ($8.7M in Q1 2025) and its impact on future operating margins.
• Liquidity Position: Confirm the company's ability to fund operations and capital expenditures given the significant cash outflows for dividends ($12.0M) and share repurchases ($23.1M) in the quarter.
