Material Changes vs. Prior Period
- Revenue Growth: Net revenues increased 7% to $215.7 million, driven by volume growth in consumer, communications, and industrial markets, particularly in China due to government subsidies.
- Profitability Surge: Net income rebounded significantly from $1.8 million in 2008 to $23.3 million in 2009. This was primarily due to a $23.6 million reduction in stock-based compensation expenses in 2009 compared to 2008.
- Stock-Based Compensation: 2008 included a $19.3 million accelerated charge related to a tender offer to repurchase underwater employee stock options. 2009 stock-based compensation was $11.3 million versus $35.0 million in 2008.
- Gross Margin Compression: Gross margin declined from 52.1% to 50.1%. Factors included a stronger Japanese Yen (increasing wafer costs), a shift in product mix toward newer, lower-margin products, and the expiration of a high-margin royalty agreement with Panasonic in mid-2009.
- Operating Expenses: Total operating expenses decreased 22% to $79.5 million, largely due to the absence of the 2008 tender offer charge and reduced stock-based compensation.
Guidance, Outlook, Risks, and Contingencies
- Outlook: Management expects continued growth driven by energy-efficiency standards (EcoSmart technology) and expansion into high-power applications (Hiper family) and LED lighting. The company anticipates cash generated from operations will satisfy working capital needs for at least the next 12 months.
- Dividends: In January 2010, the Board declared quarterly cash dividends of $0.05 per share for 2010, an increase from the $0.025 per share paid in 2009.
- Stock Repurchases: As of Dec 31, 2009, $14.0 million remained available under a $25 million repurchase program authorized in May 2009.
- Legal Proceedings:
- IRS Audit: The IRS is auditing tax returns for 2004-2006 regarding a research and development cost-sharing arrangement. The company disputes the proposed adjustments, which could materially affect results if not resolved favorably.
- Patent Litigation: Ongoing litigation against Fairchild Semiconductor and System General. While a permanent injunction was reinstated in 2009, the final damages award and willfulness determination remain pending. Litigation against BCD Semiconductor was settled in 2009.
- Azzurri Dispute: A former distributor in Germany filed a claim for approximately €1.25 million; settlement negotiations are ongoing.
- Risks: Significant reliance on international sales (95% of revenue), concentration of customers (top 10 accounted for 62% of revenue), and dependence on third-party wafer foundries (OKI, Epson, XFAB) located in Japan and Germany.
Investor Verification Checklist
- Stock-Based Compensation Normalization: Verify the sustainability of 2009 profitability by analyzing operating results excluding the one-time $19.3 million 2008 tender offer charge.
- Currency Exposure: Assess the impact of the Japanese Yen exchange rate on future gross margins, as wafer costs are partially denominated in Yen.
- Customer Concentration: Review the stability of the top two distributors (Avnet and ATM Electronic Corporation), which collectively accounted for 25% of 2009 revenue.
- Tax Liability: Monitor the status of the IRS audit regarding R&D cost-sharing, as unrecognized tax benefits totaled $24.9 million as of year-end.
- Product Mix Shift: Evaluate the long-term margin impact of the shift toward newer product families (LinkSwitch, Hiper) which currently carry lower margins than legacy products.
