Material Changes vs. Prior Period
- Revenue Growth: Total revenues increased 27% to $61.7 million, driven by a 32% increase in Design-to-Silicon-Yield solutions ($43.1 million) and an 18% increase in gainshare performance incentives ($18.6 million). This rebound was attributed to increased semiconductor industry spending and higher customer wafer volumes.
- Profitability Turnaround: The company returned to profitability with a net income of $0.2 million, compared to a net loss of $17.5 million in 2009. This was primarily due to revenue growth, reduced restructuring charges ($0.9 million in 2010 vs. $4.5 million in 2009), and lower personnel/facility expenses following prior-year cost-cutting.
- Expense Reduction: Research and Development expenses decreased 13% to $17.2 million, and Selling, General, and Administrative expenses decreased 4% to $16.0 million.
- Customer Concentration: Four customers accounted for 60% of 2010 revenues (Global Foundries 19%, Toshiba 18%, Samsung 12%, IBM 11%), compared to three customers accounting for 47% in 2009.
Guidance, Outlook, Risks, and Contingencies
- Outlook: Management expects expenses and capital expenditures to continue as material uses of cash. While the semiconductor market rebounded in 2010, growth may lessen in 2011. The company believes existing cash resources will satisfy requirements for at least the next twelve months.
- Internal Control Material Weaknesses: The company identified material weaknesses in internal controls over financial reporting as of December 31, 2010. These included a lack of resources/expertise for complex GAAP transactions, ineffective controls over revenue recognition (percentage of completion and multi-element arrangements), and stock-based compensation accounting. These weaknesses resulted in audit adjustments to the 2010 financial statements.
- Key Risks:
- Customer Concentration: Loss of any major customer could significantly reduce revenue.
- Gainshare Volatility: A significant portion of revenue is variable and dependent on customer production volumes and yield targets, which are outside the company's control.
- Market Volatility: The semiconductor industry is cyclical; a downturn could delay customer investments.
- International Operations: 65% of revenue is derived from Asia, exposing the company to foreign currency and geopolitical risks.
- Legal Proceedings: The company is defending a wrongful discharge lawsuit filed by a former employee (Philip Steven Melman). A separate lawsuit by Global Software Services, Inc. was dismissed with prejudice in December 2010.
Investor Verification Checklist
- Internal Control Remediation: Verify the progress of the remediation plan for the identified material weaknesses in revenue recognition and stock-based compensation accounting.
- Customer Retention: Monitor the status of contracts with the top four customers (Global Foundries, Toshiba, Samsung, IBM), which represent 60% of revenue.
- Gainshare Realization: Assess the sustainability of gainshare revenue, which is highly dependent on customer wafer volumes and yield performance.
- Stock Repurchase Program: Note that the company has a $10.0 million stock repurchase program extended to October 2012, with $9.95 million remaining available as of year-end.
- Out-of-Period Adjustments: Review the impact of the out-of-period adjustments recorded in Q4 2010 (totaling a $97,000 decrease to net income for the year) related to sabbatical accruals, stock-based compensation, and tax provisions.
