Business Context and Reporting Period

Company: Power Integrations, Inc.
Filing Type: Form 10-Q (Quarterly Report)
Period Ended: September 30, 2006
Business Overview: The company designs, develops, manufactures, and markets proprietary high-voltage analog integrated circuits (ICs) primarily for AC-to-DC and DC-to-DC power conversion markets. Products are sold to original equipment manufacturers (OEMs), merchant power supply manufacturers, and distributors.
Material Restatement: This filing includes a restatement of financial statements for the three and nine months ended September 30, 2005. The restatement corrects errors related to stock option compensation expenses (backdating issues), payroll tax effects, and other accounting errors identified during an internal investigation.

Key Financial Metrics

Material Changes vs. Prior Period

• Revenue Growth: Net revenues increased 21.6% for the quarter and 15.1% for the nine-month period compared to the prior year. Growth was driven by increased penetration in consumer and industrial end markets and higher sales of TinySwitch and LinkSwitch products.
• Operating Expenses: Operating expenses increased significantly as a percentage of revenue. General and Administrative (G&A) expenses rose from 11.6% to 23.0% of revenue for the quarter. This increase is primarily due to approximately $4.7 million in professional fees related to the internal investigation of stock option practices and the financial restatement, as well as patent litigation costs.
• Stock-Based Compensation: The adoption of SFAS 123R (Share-Based Payment) effective January 1, 2006, resulted in a significant increase in stock-based compensation expense. Total stock-based compensation for the nine months ended September 30, 2006, was $11.8 million, compared to $2.3 million for the same period in 2005 (restated).
• Profitability: Despite revenue growth, Net Income decreased significantly year-over-year due to the surge in G&A expenses and stock-based compensation. Operating income dropped from $4.96 million to $1.18 million for the quarter.
• Liquidity: Cash and cash equivalents decreased slightly from $109.9 million to $101.5 million. The company utilized $19.6 million for stock repurchases during the nine-month period, concluding a $25 million repurchase program.

Guidance, Outlook, Risks, and Contingencies

• Legal Proceedings:
  • Patent Litigation: The company is engaged in patent infringement lawsuits against System General Corporation, Fairchild Semiconductor, and BCD Semiconductor. A jury awarded the company approximately $34 million in damages against Fairchild in October 2006, though a second trial regarding patent validity is scheduled for September 2007. The company has not recorded any benefit from this award.
  • Derivative Suits & Investigations: Multiple shareholder derivative lawsuits have been filed against current and former executives regarding stock option backdating. The company is also cooperating with investigations by the SEC and the U.S. Department of Justice (DOJ) regarding stock option practices.
  • Tax Audit: The IRS is auditing the company's 2002 and 2003 tax returns, specifically challenging research and development cost-sharing arrangements.
• Internal Controls: Management concluded that internal controls over financial reporting were not effective as of September 30, 2006, citing three material weaknesses: accounting for stock option grants, income tax accounting, and the application of GAAP to non-routine transactions. Remediation efforts are underway.
• NASDAQ Delisting: The company's common stock was delisted from the NASDAQ Stock Market due to failure to timely file required reports. Shares are currently trading on the Pink Sheets under the symbol "POWI.PK".
• Outlook: Management expects G&A expenses to remain at a significantly higher percentage of net revenues throughout 2006 due to investigation and litigation costs. The company believes its cash and operating cash flow will satisfy requirements for at least the next 12 months.

Key Facts for Investor Verification

• Restatement Impact: Verify the full extent of the financial restatement for periods prior to 2006, which corrected approximately $30.5 million in incremental stock-based compensation expenses (net of tax benefits) dating back to 1998.
• Legal Exposure: Monitor the outcome of the second trial against Fairchild Semiconductor regarding patent validity, as a loss could invalidate the $34 million jury award and expose the company to liability.
• Regulatory Investigations: Track the status of the SEC and DOJ investigations into stock option backdating, as these could result in fines, penalties, or further restatements.
• Stock Repurchase Program: Confirm that the $25 million stock repurchase program was fully utilized and that no new repurchase programs have been authorized.
• Customer Concentration: Note that the top ten customers accounted for 58% of net revenues for the nine months ended September 30, 2006, creating concentration risk.
• Delisting Status: Verify the company's progress in filing delinquent reports to regain compliance with NASDAQ listing requirements.
