Debt & Liquidity: The company reported no long-term debt. Total assets were $195.3 million. However, liquidity is impacted by $38.8 million in face value of government-backed student loan auction-rate securities that failed to reset and are currently illiquid. As of Dec 31, 2008, these were recorded at $37.4 million (net of impairment charges).
Material Changes vs. Prior Period
- Revenue Growth: Revenue increased 19.8% year-over-year, driven primarily by a 33.1% increase in DC to DC converter sales ($115.4 million). This growth offset a 9.5% decline in LCD Backlight Inverter sales due to decreased demand in the notebook computer market.
- Profitability: Net income more than doubled to $24.2 million, despite a slight compression in gross margin (61.9% vs 63.6%) attributed to lower average selling prices and increased inventory reserves in Q4.
- Operating Expenses: Total operating expenses increased slightly to $76.8 million. Notably, the "Patent litigation settlement" expense dropped to zero from $9.8 million in 2007. However, "Provision for litigation" remained significant at $6.7 million.
- Stock Repurchase: The company utilized $25.0 million of cash to repurchase 1.43 million shares of common stock during 2008.
Guidance, Outlook, Risks, and Contingencies
Outlook & Commentary: Management noted that while the company achieved revenue growth, the fourth quarter was affected by the worldwide financial crisis and macro-economic slowdown. The company cannot currently estimate the magnitude of future impacts. The company expects to continue introducing new products but faces challenges in forecasting due to the cyclical nature of the industry.
Key Risks & Contingencies:
- Litigation: Ongoing patent infringement proceedings with O2Micro, Inc. (U.S. and Taiwan), Taiwan Sumida Electronics (TSE), and Chip Advanced Technology Inc. (CAT). An unfavorable outcome could prevent product sales or require substantial damages. $7.4 million remains held in escrow related to the TSE settlement.
- Liquidity Risk (Auction-Rate Securities): $38.8 million of investments in auction-rate securities are illiquid. While the underlying credit quality is AAA, the company recorded $2.7 million in total impairment charges ($1.4 million temporary, $1.3 million other-than-temporary). The company has a put right with UBS to sell up to $18.2 million of these securities at par commencing in June 2010.
- Customer Concentration: Two customers (Customer A and Customer B) accounted for 20% and 10% of total revenue, respectively, in 2008.
- Geographic Concentration: 89% of revenue is derived from Asia, exposing the company to regional economic, political, and currency risks.
Investor Verification Checklist
- Litigation Status: Verify the current status of the O2Micro and TSE legal proceedings and the potential impact of the $7.4 million escrow liability.
- Investment Portfolio: Confirm the liquidity status of the $38.8 million auction-rate securities and the likelihood of the UBS put right being exercised at par.
- Inventory Levels: Review inventory write-downs and reserves, particularly given the Q4 economic slowdown and the company's fabless model requiring advance manufacturing orders.
- Customer Concentration: Assess the stability of the top two customers (30% combined revenue) and their exposure to the consumer electronics downturn.
- Product Mix Shift: Monitor the trend of declining LCD Backlight Inverter revenue versus the growth in DC to DC converters to ensure long-term diversification.
