Key Financial Metrics

Material Changes vs. Prior Period

• Revenue Growth: Net revenues increased 26.3% for the quarter and 30.2% for the six-month period compared to the prior year. Growth was driven primarily by a 50-58% increase in "other markets" (e.g., set-top decoder boxes) rather than the traditional cellular phone and PC stand-by markets.
• Margin Compression: Gross margin declined from 54.5% to 52.1% (six-month comparison). This was attributed to increased customer pricing pressure and higher wafer costs due to a stronger Japanese yen, partially offset by improved manufacturing yields.
• Expense Increases: Operating expenses rose significantly. R&D expenses increased 33.2% (six-month) due to hiring and new product development. Sales and marketing expenses increased 31.6% to support sales growth and field application engineering.
• Customer Concentration: The top 10 customers accounted for approximately 70.7% of revenues for the six months ended June 30, 2000. Sales to Motorola (direct and indirect) represented approximately 13.3% of revenues for the six-month period.
• Inventory Build: Inventories increased from $11.4 million to $18.9 million, resulting in a $7.6 million cash outflow from operating activities.

Outlook, Risks, and Management Commentary

• Liquidity: The Company holds approximately $65.7 million in cash, cash equivalents, and short-term investments. It maintains a $10 million revolving line of credit with Union Bank of California, which is currently unused except for letters of credit.
• Seasonality: Management notes that revenues are historically strongest in the third and fourth quarters, with the first and second quarters often being sequentially linear or down.
• Key Risks:
  • Customer Dependence: Significant reliance on Motorola and a small number of OEMs/distributors. Loss of a major customer could materially harm results.
  • Supply Chain: Dependence on third-party foundries (Matsushita and OKI) for wafer production. Switching suppliers would take 9-12 months.
  • Competition: Intense competition in the high-voltage power supply industry leading to price erosion.
  • Market Volatility: Quarterly results are volatile and difficult to predict due to the cyclical nature of the semiconductor industry and customer ordering patterns.
• Accounting Updates: The Company expects to adopt SAB 101 (Revenue Recognition) in the fourth quarter of 2000 and SFAS 133 (Derivatives) for fiscal years beginning after June 15, 2000. Neither is expected to have a material impact.

Investor Verification Checklist

• Verify the sustainability of revenue growth in "other markets" versus the core cellular and PC markets.
• Monitor the impact of the Japanese yen exchange rate on wafer costs and gross margins.
• Assess the risk associated with the top 10 customers representing ~71% of total revenue.
• Review the inventory build-up ($7.6M increase) to ensure it aligns with future demand forecasts and does not indicate obsolescence.
• Confirm the Company's ability to maintain supply capacity with foundry partners Matsushita and OKI.
