Key Financial Metrics

Note: 2005 was the company's first profitable full year of operations. The company had an accumulated deficit of $15.1 million as of December 31, 2005.

Material Changes vs. Prior Period

• Revenue Growth: Revenue increased 108.3% year-over-year, driven by a 137% increase in DC to DC Converter sales and a 74% increase in LCD Backlight Inverter sales.
• Profitability: The company transitioned from a net loss of $3.7 million in 2004 to a net income of $5.1 million in 2005.
• Expense Increases: Patent litigation expenses more than doubled to $18.4 million (18.5% of revenue) due to multiple trials and settlements. A new $5.0 million provision for litigation awards and settlements was recorded in 2005.
• Stock-Based Compensation: Total stock-based compensation expense decreased significantly from $11.6 million in 2004 to $5.4 million in 2005, primarily due to the amortization method and new grants at fair market value.
• Liquidity: While cash equivalents decreased, total liquid assets (cash + short-term investments) increased to $63.9 million, bolstered by the November 2004 IPO proceeds.

Guidance, Outlook, Risks, and Contingencies

Outlook and Guidance

Management expects operating results for the first quarter of fiscal 2006 to be adversely affected due to lower-than-expected shipment volumes. This is attributed to distributors overestimating demand in Q4 2005 and the impact of ongoing litigation. The company anticipates continued investment in R&D and the adoption of SFAS 123R (Share-Based Payment) in 2006, which will materially impact results of operations.

Material Risks and Contingencies

• Legal Proceedings (O2 Micro): Ongoing litigation with O2 Micro regarding patent infringement and trade secret misappropriation poses a severe risk. A jury previously awarded O2 $12 million, later reduced by a judge to $2.7 million plus interest. An appeal is pending. Adverse outcomes could result in injunctions preventing sales of CCFL products in the U.S. and Taiwan.
• Legal Proceedings (Micrel): Litigation with Micrel Corporation alleges patent infringement and trade secret misappropriation involving the company's CEO and Chief Design Engineer. An unfavorable outcome could enjoin the sale of all products.
• Internal Controls: The company identified material weaknesses in internal controls over financial reporting, specifically regarding stock-based compensation, income tax accounting, and the financial close process. These weaknesses led to restatements of prior periods. An adverse opinion was issued by auditors regarding the effectiveness of internal controls.
• Customer Concentration: The three largest customers (all distributors) accounted for 54% of total revenue in 2005.
• Supply Chain: The company relies on a single foundry (ASMC) for wafer production. Disruptions or capacity constraints could materially impact revenue.

Investor Verification Checklist

• Legal Exposure: Verify the current status of the O2 Micro appeal and the potential for reinstatement of the $12 million verdict or injunctive relief.
• Internal Control Remediation: Assess the progress of hiring qualified finance staff and implementing new processes to remediate the identified material weaknesses in internal controls.
• Q1 2006 Performance: Monitor Q1 2006 results to confirm the severity of the anticipated revenue decline due to distributor inventory corrections.
• Accounting Changes: Review the impact of the upcoming adoption of SFAS 123R on future stock-based compensation expenses.
• Customer Concentration: Evaluate the stability of relationships with the top three distributors, which represent over half of total revenue.
