CluenexAmkor Technology AMKR
Amkor Technology scores weak on business quality (4.1 of 10). Here is why, in plain words, and what our sealed record shows.
Why it matters
- What Amkor Technology does
Amkor Technology provides outsourced semiconductor packaging and test services, turning raw silicon wafers into finished chips for global electronics brands. Chipmakers and designers pay Amkor to handle the complex final assembly phase before devices ship to end markets.
- What it does best
Amkor excels in advanced semiconductor packaging and test services, but its gross margin sits at 15.5% compared to Teradyne at 59.2%, reflecting the lower-margin, labor-heavy nature of outsourced assembly work.
- The main risk
Heavy capital expenditure demands threaten cash generation, with free cash flow dropping to negative $172 million as capital spending reached $1.36 billion to build out new packaging lines.
Quality, check by check
Scored against its own industry, from company filings.
Gross margin is 15.5% and operating margin is 8.6%, driven down by heavy manufacturing and packaging costs. Scale does not yield high operating leverage due to high capital intensity.
Amkor relies on customer switching costs tied to long-standing qualification processes for chip packaging. However, a gross margin in the bottom 5% of its sector limits true pricing power.
Revenue grew 6.2% to $7.45 billion, showing a slight recovery compared to the dip seen in 2023, though growth remains sluggish overall sitting in the bottom quartile of its sector.
Debt-to-equity is manageable at 0.33 and interest coverage sits at 8.4x, but free cash flow turned negative at -$172 million due to heavy capital outlays, getting softer.
