Is it selling more, and how much does it keep?
KIRA · Amkor Technology had $6.7B of revenue in fiscal 2025, up 6.2% on the year before. Over five years, revenue changed +5.8% a year on average. Its operating margin was 7.0%, up 0.0 pts: of every 100 in sales, about 7 is left after running the business.

How much cash comes in, and where does it go?
KIRA · Free cash flow was $191M in fiscal 2025, 2.9% of revenue.

Open-market purchases and sales by officers, directors and 10% owners, from Form 4 filings. “Plan” marks trades under a pre-arranged Rule 10b5-1 plan.
