Corporate Governance

Stakeholder Impact

• Shareholders: Benefit from increased dividends and potential long-term growth from strategic investments, but face near-term uncertainty due to cautious Q1 2026 guidance.
• Employees: Strategic investments in advanced packaging could lead to job growth and opportunities in high-growth areas of the semiconductor industry.
• Customers: Continued investment in advanced packaging and test services ensures Amkor can deliver high-quality solutions for advanced technologies.
• Creditors: Increased long-term debt indicates higher leverage, which could be a concern if future cash flows do not meet expectations, though current cash position is strong.

Next Steps

• Amkor will conduct a conference call on February 9, 2026, at 5:00 p.m. Eastern Time to discuss the results.
• The declaration and payment of future dividends, as well as any record and payment dates, are subject to the approval of the Board of Directors.
• Accelerating strategic investments to support the next wave of advanced packaging growth, with full year 2026 capital expenditures projected at $2.5 billion to $3.0 billion.

Key Dates

Recommendation

The strong full-year 2025 performance, particularly in advanced packaging, and the commitment to significant strategic investments for future growth are positive. However, the notably weaker guidance for Q1 2026 in terms of sales, gross margin, and net income introduces near-term uncertainty. The increased debt to fund growth also warrants caution. A 'hold' recommendation allows investors to observe if the strategic investments translate into improved performance beyond Q1 2026, balancing the strong past results with the cautious immediate outlook.
