Risks common in this industry

These are general risks for companies in the semiconductor materials & equipment industry. They are not a summary of KLA’s own risk factors; for those, read Item 1A of its latest 10-K, linked below.

Chip cyclesDemand for chips swings between shortages and gluts, and orders can be cut quickly.
Customer concentrationA few large customers can account for much of sales.
Export rules and tradeExport controls and tariffs can limit sales to some customers or countries.
Manufacturing supplyIt depends on outside factories and suppliers, and disruptions can delay products.
Competition and design winsCustomers pick suppliers product by product, so losing a design can cost years of sales.

Each row is that company’s latest fiscal year from its own 10-K, using its own revenue and net income lines. Fiscal years end in different months, and line definitions differ (banks, insurers and oil companies count revenue differently), so this is a rough side-by-side, not a like-for-like comparison.
