Key Financial Metrics

Material Changes vs. Prior Period

• Revenue Growth: Total revenue increased 5% for the quarter and 4% for the nine-month period compared to the prior year.
  • Integrated Solutions: Decreased 19% (quarter) and 12% (nine months) due to slower booking rates in late 2005 and early 2006.
  • Software Licenses: Increased 149% (quarter) due to greater adoption; remained flat for the nine-month period.
  • Gain Share: Increased 42% (quarter) and 88% (nine months) driven by higher customer wafer starts and more contracts reaching performance thresholds.
• Profitability Decline: Net income dropped from $1.5 million to $0.6 million for the quarter, and the nine-month period shifted from a $4.3 million profit to a $9,000 loss.
  • Primary Driver: Adoption of SFAS No. 123(R) resulted in a $1.5 million (quarter) and $5.4 million (nine months) increase in stock-based compensation expense.
  • Operating Expenses: R&D and SG&A expenses increased significantly due to stock-based compensation, new office openings (Shanghai), and higher legal/accounting fees.
• Cash Flow: Net cash provided by operating activities decreased to $6.5 million for the nine months ended Sep 30, 2006, from $10.1 million in the prior year period. Investing activities consumed $18.9 million, primarily due to net purchases of short-term investments ($17.0 million).

Guidance, Outlook, and Risks

• Subsequent Event: On October 31, 2006, the company acquired Si Automation S.A. for approximately $35.6 million in aggregate consideration (cash and stock). This is expected to increase future amortization expenses.
• Liquidity: Management believes existing cash resources ($69.9 million in cash and short-term investments) and anticipated funds from operations will satisfy requirements for at least the next 12 months.
• Key Risks:
  • Customer Concentration: Three customers accounted for 49% of revenue in the first nine months of 2006 (IBM 27%, Toshiba 12%, Chartered Semiconductor 10%).
  • Gain Share Volatility: A significant portion of revenue is variable and dependent on customer production volumes and yield improvements, which are outside the company's control.
  • Accounting Changes: Continued impact of SFAS No. 123(R) on reported earnings and potential future adoption of FIN 48 (Income Tax Uncertainty).
  • International Operations: 50% of revenue is derived from Asia, exposing the company to currency fluctuations and geopolitical risks.

Investor Verification Checklist

• Revenue Mix Sustainability: Verify if the decline in fixed-price "Integrated Solutions" revenue is offset by the growth in variable "Gain Share" revenue in future quarters.
• Stock-Based Compensation Impact: Assess the long-term effect of SFAS No. 123(R) on operating margins and the company's ability to retain talent without excessive dilution.
• Customer Concentration: Monitor the stability of the top three customers (IBM, Toshiba, Chartered) given they represent nearly half of total revenue.
• Acquisition Integration: Evaluate the integration progress and financial impact of the Si Automation S.A. acquisition completed in October 2006.
• Cash Burn vs. Generation: Confirm that operating cash flow remains sufficient to cover the increased R&D and SG&A expenses without requiring external financing.
