Business Context and Reporting Period

Advanced Semiconductor Engineering, Inc. (ASE) filed a Form 6-K on April 9, 2004, reporting unaudited consolidated net revenues for March 2004 and the first quarter of 2004. The company operates primarily in semiconductor packaging and testing, with significant operations in Kaohsiung, Taiwan, and various subsidiaries.

Key Financial Metrics

The filing does not provide specific figures for profit, cash flow, margins, debt, or liquidity.

Material Changes

• Revenue Performance: Q1 2004 consolidated revenues were slightly below the company's original forecast.
• Sequential Decline: Q1 2004 revenues decreased by 6.56% compared to Q4 2003.
• Year-over-Year Growth: Despite the sequential decline, Q1 2004 revenues grew 48.66% compared to Q1 2003.
• Operational Constraints: The shortfall was attributed to unexpected capacity constraints at foundries, which limited customer wafer allocations and reduced production volumes toward the end of the quarter.

Guidance, Outlook, and Risks

• Outlook: Management reaffirms its guidance for 50% year-over-year revenue growth for the full year 2004.
• Trend: The company continues to observe sequential revenue growth on a monthly basis (March 2004 was up 8.49% from February 2004).
• Risks: The primary risk identified is dependency on foundry capacity, which can constrain production volumes and impact revenue realization.

Investor Verification Checklist

• Verify the extent of foundry capacity constraints and their expected duration.
• Confirm the specific impact of internal sales elimination on consolidated revenue figures (e.g., ASE Material Inc. revenues).
• Monitor subsequent monthly reports to validate the trajectory toward the 50% full-year growth target.
• Review the breakdown of revenue between Kaohsiung operations and other subsidiaries to assess geographic concentration risks.
