Key Financial Metrics

Note: All figures in millions unless otherwise noted. Percentages represent margin of net revenues.

Material Changes vs. Prior Period

• Revenue Growth: Net revenues increased 20.6% for the quarter and 19.1% for the six-month period compared to the prior year. Growth was driven primarily by a 43% increase in the consumer end market (set-top boxes, DVD players, home appliances).
• Gross Margin Compression: Gross profit margin declined from 50.8% to 46.0% for the quarter and from 51.3% to 47.4% for the six-month period. Management attributed this to lower overhead absorption due to inventory reduction and the strengthening of the Japanese yen.
• Operating Expenses: While absolute operating expenses remained relatively flat or increased slightly, they decreased as a percentage of revenue due to top-line growth. R&D was 11.3% of revenue (vs. 14.0% prior year) and Sales & Marketing was 11.0% (vs. 13.2% prior year).
• Cash Flow: Operating cash flow improved significantly to $16.9 million for the six months ended June 30, 2004, compared to $4.7 million in the prior year period, aided by a $3.3 million decrease in inventory.

Outlook, Risks, and Contingencies

• Guidance: The filing does not provide specific numerical guidance for future quarters. Management notes that quarterly results are volatile and difficult to predict due to short-term orders and unpredictable customer demand.
• Legal Proceedings: On June 28, 2004, the Company filed a patent infringement lawsuit against System General Corporation in the U.S. District Court, Northern District of California. The Company seeks an injunction and damages. Management warns that litigation is costly and could divert management attention.
• Customer Concentration: The top ten customers accounted for approximately 70.7% of revenues for the quarter and 71.2% for the six-month period. Two distributors (Customer A and B) and one OEM (Customer C) each accounted for over 10% of revenues.
• Supply Chain Risks: The Company relies on third-party foundries (Matsushita and OKI) for wafer supply. Contracts are denominated in Japanese yen, creating foreign exchange risk. A third foundry (ZMD) is expected to begin production by the end of 2004.
• Accounting Policy: The Company follows APB No. 25 for stock-based compensation. Pro forma net income under SFAS No. 123 (fair value method) would have resulted in a net loss of $0.3 million for the quarter and $0.3 million for the six-month period.

Key Investor Verification Points

• Customer Concentration: Verify the stability of the top three customers (approx. 48% of Q2 revenue) and the impact of distributor inventory levels on deferred revenue recognition.
• Gross Margin Trends: Monitor the impact of the Japanese yen exchange rate and overhead absorption on future gross margins, which have compressed year-over-year.
• Legal Exposure: Track the progress of the patent infringement suit against System General Corporation and potential costs or injunctions.
• Stock-Based Compensation: Assess the potential impact of future GAAP changes requiring fair-value accounting for stock options, which currently masks significant compensation costs.
• Supply Chain Diversification: Confirm the timeline and yield performance of the new wafer foundry (ZMD) to mitigate reliance on Matsushita and OKI.
