Key Financial Metrics

Material Changes vs. Prior Period

• Revenue Growth: Revenue increased 19.5% year-over-year (YoY) for the quarter and 39.2% for the six-month period. This was driven primarily by a 46.0% increase in DC to DC converter sales.
• Profitability Turnaround: The company returned to profitability, reporting net income of $1.1 million for the quarter compared to a net loss of $6.7 million in the same period in 2005. This improvement is largely due to a significant reduction in patent litigation expenses.
• Litigation Expenses: Patent litigation costs dropped dramatically to $2.8 million for the quarter (10.6% of revenue) from $17.4 million (78.1% of revenue) in the prior year quarter. The prior year included a $12 million provision for litigation.
• Operating Expenses: R&D and SG&A expenses increased significantly (44.6% and 47.9% respectively for the quarter) due to headcount expansion and the adoption of SFAS 123(R) for stock-based compensation.
• Effective Tax Rate: The estimated effective tax rate increased to 66% for the full year 2006 (from 37.7% in Q1), driven by non-deductible stock-based compensation and international tax structure changes.

Guidance, Outlook, Risks, and Unusual Items

• Internal Controls: Management concluded that disclosure controls and procedures were not effective as of June 30, 2006. Material weaknesses were identified regarding stock-based compensation accounting, income tax calculations, and the financial close process. Remediation efforts are ongoing.
• Litigation Risks:
  • O2 Micro: Ongoing disputes in the U.S. and Taiwan regarding patent infringement and trade secrets. A $3.5 million provision exists for one U.S. case. A preliminary injunction in Taiwan restricts certain products, though counter-injunctions are in place. The company has posted $6.1 million in cash bonds in Taiwan.
  • Taiwan Sumida Electronics (TSE): TSE is seeking indemnification for a $4 million judgment against them by O2 Micro. Trial is scheduled for July 2007.
  • Micrel & Linear Technology: New or ongoing patent infringement suits filed by Micrel and Linear Technology. The company cannot currently estimate potential losses.
• Product Mix Shift: While DC to DC converters grew, LCD Backlight Inverter revenue declined 17.2% YoY due to customer concerns over O2 Micro litigation and a weak notebook market.
• Stock-Based Compensation: Adoption of SFAS 123(R) on Jan 1, 2006, resulted in significant non-cash expenses ($5.8 million for the six months ended June 30, 2006).

Investor Verification Checklist

• Internal Control Remediation: Verify the progress of the remediation plan for material weaknesses in financial reporting, specifically regarding stock compensation and tax accounting.
• Litigation Exposure: Monitor developments in the O2 Micro, Micrel, and Linear Technology cases, particularly the potential for injunctions or large damage awards that could impact liquidity.
• Tax Rate Volatility: Assess the sustainability of the 66% effective tax rate and the impact of stock-based compensation on future net income.
• Customer Concentration: Review the top customer list; two customers accounted for over 30% of revenue in the quarter, creating concentration risk.
• Inventory Levels: Monitor inventory build-up ($9.1 million) relative to sales, given the history of distributor inventory corrections affecting revenue timing.
