Filing Type: Form 10-Q (Unaudited)
Reporting Period: Three months ended March 31, 2004
Business Overview: The Company designs, develops, manufactures, and markets proprietary high-voltage analog integrated circuits (ICs) for AC to DC and DC to DC power conversion.

Note: All figures in millions unless otherwise noted. The filing does not disclose long-term debt; the Company maintains a $10.0 million revolving credit line with $5.2 million utilized for letters of credit.

Material Changes vs. Prior Period

• Revenue Growth: Net revenues increased 17.4% year-over-year, driven primarily by a 47% increase in the consumer end market (set-top boxes, DVD players, home appliances).
• Margin Compression: Gross margin decreased from 51.8% to 48.9%. Management attributed this to a stronger Japanese Yen (impacting wafer costs) and a slight decline in average selling prices due to product mix.
• Expense Management: Operating expenses increased slightly in absolute dollars but decreased as a percentage of revenue (28.8% in 2004 vs. 33.5% in 2003), improving operating leverage.
• Customer Concentration: The top 10 customers accounted for 72.3% of revenues in Q1 2004, down from 78.7% in Q1 2003. Two distributors (Customers A and B) accounted for 22.4% and 15.4% of revenues, respectively.
• Geographic Mix: International sales represented 91.8% of total revenues, a slight decrease from 94.2% in the prior year.

Outlook, Risks, and Management Commentary

• Guidance & Mix: Management expects the full-year 2004 revenue mix to shift toward TinySwitch (50%) and TOPSwitch FX/GX (30%). The effective tax rate is expected to remain at 28% for 2004.
• Liquidity: The Company holds approximately $123.5 million in cash, cash equivalents, and investments. Management believes existing liquidity and operating cash flow will satisfy requirements for at least the next 12 months.
• Key Risks:
  • Customer Concentration: Reliance on a small number of distributors and OEMs; orders are short-term and can be canceled without penalty.
  • Supply Chain: Dependence on third-party foundries (Matsushita and OKI) for wafers. A disruption could take 9-18 months to resolve. A third source (ZMD) is expected to begin production by end of 2004.
  • Currency: Wafer costs are denominated in Japanese Yen, exposing gross profit to exchange rate fluctuations.
  • Volatility: Quarterly results are difficult to predict due to short lead times and "turns business" (orders booked and shipped in the same period).
• Accounting Note: The Company follows APB No. 25 for stock-based compensation. Pro forma net income under SFAS No. 123 would have been $0.8 million (vs. reported $5.1 million) for Q1 2004.

Investor Verification Checklist

• Customer Concentration: Verify the stability of the top two distributors (Customer A and B), which collectively represent over 37% of revenue.
• Wafer Supply Security: Confirm the status of the new wafer supply agreement with ZMD and the capacity commitments from Matsushita and OKI.
• Currency Exposure: Monitor the USD/JPY exchange rate, as a stronger Yen directly reduces gross margins.
• Inventory Levels: Review inventory trends (decreased $1.8M in Q1 2004) to ensure they align with demand forecasts and do not indicate obsolescence risks.
• Stock-Based Compensation: Assess the potential impact of future GAAP changes requiring fair-value accounting for stock options, which could significantly reduce reported net income.
