How Amkor Technology's quarter compared with the analysts' estimate
Amkor has beaten the analysts' average estimate in 3 of the last eight reported quarters, and this quarter's miss sits within that pattern.
Profit is outgrowing sales
Revenue growth decelerated this quarter. The 0.2% pace was slower than in 6 of the previous eight quarters, and the trailing twelve month growth rate of 15.7% is down 2.2 percentage points from the previous quarter's trailing figure.
Operating margin moved the opposite way. The trailing margin reached 9.5%, up 3.0 percentage points from a year earlier, while net income rose 101.3% against that 15.7% revenue growth. More of each extra dollar of revenue reached the bottom line.
Cash flow moved against that trend. Free cash flow over the trailing twelve months was negative, at −$156.1 million, equal to −2.1% of revenue, as capital spending rose 120.1% and operating cash flow rose 53.0% over the same period, leaving less for shareholders.
What Amkor Technology now guides to
For the fourth quarter of 2026, Amkor guided net sales to $1.9 billion to $2.0 billion, gross margin to 18% to 19%, net income to $160.0 million to $185.0 million, and diluted EPS to $0.65 to $0.75.
How the market took Amkor Technology's results
The shares rose 1.6% after the release, smaller than the 8.3% typical move for the stock on report days, while the S&P 500 gained 1.3% in the same session. The results release does not say why the shares moved.

What Amkor Technology's next report has to show
The next report will show whether the operating margin expansion continues or reverses, and whether revenue growth re-accelerates from the current pace. The free cash flow position will test whether capital spending moderates or deepens the outflow. Guidance for the following period will frame whether management expects the current margin trajectory to hold.
