The company operates on a fabless model, contracting wafer manufacturing to Matsushita and OKI in Japan.

Key Financial Metrics (Year Ended Dec 31, 2002)

Note: All figures in millions except per share data.

Material Changes vs. Prior Period

• Revenue Growth: Net revenues increased 15.0% to $108.2 million in 2002 compared to 2001, driven by increased sales in communications and computer markets and market share gains, despite a weak overall market environment.
• Margin Compression: Gross margin declined from 45.5% in 2001 to 43.9% in 2002. Management attributed this to lower manufacturing efficiencies during new product introductions and increased pricing pressure from customers.
• Profitability: Net income increased 42.4% to $9.6 million, outpacing revenue growth due to better expense control in sales and marketing relative to revenue.
• Customer Concentration: The top 10 customers accounted for 81% of net revenues in 2002, up from 74% in 2001. Two distributors (Memec and Synnex) and one OEM (Samsung) accounted for 51% of total revenue.
• International Sales: International sales comprised 96% of total net revenues, an increase from 93% in 2001.

Guidance, Outlook, and Risks

• 2003 Outlook: Management expects operating expenses to increase in absolute dollars. Gross profit is projected to range between 48% and 50% in 2003, contingent on improved manufacturing efficiencies and the absence of severe pricing pressure.
• Supply Chain Risks: The company relies entirely on two foundries (Matsushita and OKI) for wafer production. The agreement with OKI expires in September 2003 and is currently under renegotiation. Failure to secure an extension or alternative source could disrupt supply.
• Competition: The industry faces intense price competition from discrete switchers and emerging hybrid ICs from competitors like ON Semiconductor and STMicroelectronics. Price erosion in discrete components threatens the cost-effectiveness of Power Integrations' products.
• Accounting Change: The company dismissed Arthur Andersen LLP in June 2002 and engaged KPMG LLP as its new independent auditor. No disagreements were reported regarding accounting principles.
• Market Risks: Significant exposure to fluctuations in the Japanese Yen exchange rate, as wafer costs are denominated in Yen. Additionally, the company faces risks related to the California energy crisis and potential supply disruptions from earthquakes in the Far East.

Investor Verification Checklist

• Wafer Supply Agreements: Verify the status of the renegotiation with OKI (expiring Sept 2003) and the terms of the Matsushita agreement (expiring June 2005) to assess supply continuity risks.
• Customer Concentration: Monitor the stability of the top three customers (Memec, Synnex, Samsung), which collectively represent over 50% of revenue.
• Gross Margin Trends: Track whether the projected 48-50% gross margin for 2003 is achieved, given the history of pricing pressure and new product introduction inefficiencies.
• Inventory Levels: Review inventory turnover and reserves for excess/obsolete inventory, as the company carries substantial inventory to offset long lead times from foundries.
• Stock-Based Compensation: Note that the company follows APB 25 rather than SFAS 123; pro forma net income under SFAS 123 would have been negative ($-4.8 million) for 2002.
