Our core focus is enabling technological advances and improving manufacturing yields in the semiconductor industry. The semiconductor fabrication process begins with a bare silicon wafer - a round disk typically 200 millimeters or 300 millimeters in diameter, about as thick as a credit card and gray…
The manufacturing cycle of an IC is grouped into three phases: design, fabrication and testing. IC design involves the architectural layout of the circuit, as well as design verification and reticle generation. The fabrication of a semiconductor chip (or “semiconductor”) is accomplished by depositin…
on bare wafers. The deposition of these film layers is interspersed with numerous other process steps that create circuit patterns, remove portions of the film layers, and perform other functions such as heat treatment, measurement and inspection. Most advanced chip designs require hundreds of indiv…
Our business depends upon the capital expenditures of semiconductor, semiconductor-related and electronic device manufacturers. This is driven by the current and anticipated market demand for ICs, products utilizing ICs and other electronic components. We do not consider our business to be seasonal.…
Companies anticipating future market demands by developing and advancing new technologies and manufacturing processes are better positioned to lead in the semiconductor market. Accelerating the yield ramp and maximizing production yields of high-performance devices are critical goals of modern semic…

Our semiconductor customers generally operate in one or both of the major semiconductor device manufacturing markets: memory and foundry/logic. End-market demand drivers that are expected to continue to benefit KLA in the long term include adoption of EUV in HVM for Logic and DRAM memory, which driv…
A majority of our revenues are derived from outside the U.S., and include geographic regions such as China, Taiwan, Korea, Japan, Europe and Israel, and Rest of Asia. China remains a major region for manufacturing of legacy node logic and memory chips, adding to its role as the world’s largest consu…
The recent imposition of tariffs by the U.S. government, along with countermeasures taken by foreign countries, have had an adverse impact on our results of operations, though the impact was not material in fiscal year 2025. There continues to be uncertainty around the ultimate duration, size and su…
countries. However, despite headwinds from tariffs, our gross margin and overall financial performance improved in fiscal year 2025 compared to fiscal year 2024 due to higher revenue volume on products and services sold and cost management.

How to read Risk Factors (Item 1A) in a 10-Q
A 10-Q risk-factor section usually takes one of three forms; this page classifies it as one of:
- Pointer — the filer states there have been no material changes and points back to the annual 10-K risk factors; there is no own risk text to compare this quarter.
- Partial update — the filer carves out specific updated risks ("except as set forth below"); the excerpts show exactly what is new this quarter.
- Restated in full — the quarter carries the complete risk-factor text. When the prior quarter was only a pointer there is no prior full text to diff against, so the page flags the section as restated instead.
This describes the filing structure only — it is never a judgement on whether risk went up or down.
