What does KLA do?
KLA builds the systems that inspect and measure chips while they are being made. Its tools scan wafers and photomasks for defects and measure critical dimensions at each step, so a fab can catch a process drift before it ruins thousands of wafers. The company reports three segments, but one dominates: Semiconductor Process Control was $3.08 billion, about 90% of fiscal Q3 2026 revenue, alongside smaller Specialty Semiconductor Process and PCB & Component Inspection units (KLA 8-K, Apr 29, 2026). KLA is the clear leader in process-control wafer-fab equipment, a position rivals have found hard to contest because inspection sensitivity compounds with decades of installed data.
How is AI driving KLA’s business?
Through the cost of a defect at the leading edge. As logic moves to gate-all-around transistors and EUV patterning, and as memory stacks into HBM and chips fan out into advanced packages, the number of places a defect can hide multiplies and each one is more expensive to miss. That makes inspection and metrology a larger share of every fab’s budget, and KLA describes itself as a key enabler of the AI ecosystem across foundry/logic, memory, advanced packaging, and services (KLA 8-K, Apr 29, 2026). The AI build-out shows up directly in the numbers: revenue rose 11% year over year to $3.42 billion. President and CEO Rick Wallace tied the quarter to the cycle ahead:
“KLA delivered strong March quarter results exceeding the midpoint of our guidance ranges on both revenue and earnings per share. Our business momentum remains robust, and we are highly confident in our outlook for calendar year 2026.”
— Rick Wallace, President and CEO, KLA Corporation (KLA 8-K, Apr 29, 2026)
What did KLA report most recently?
In fiscal Q3 2026 (the quarter ended March 31, 2026), revenue was $3.42 billion, up about 11% year over year, with GAAP net income of $1.20 billion and non-GAAP net income of $1.24 billion (KLA 8-K, Apr 29, 2026). On a split-adjusted basis GAAP diluted EPS was $0.91 and non-GAAP EPS $0.94, and the GAAP gross margin was near 61%. Semiconductor Process Control was $3.08 billion, roughly 90% of the total. All per-share figures reflect the 10-for-1 stock split that took effect on June 11, 2026, which also restated the quarterly dividend from $2.30 to $0.23 per share (KLA 8-K, Jun 2026).
What is KLA’s guidance?
For fiscal Q4 2026, KLA guided revenue to $3.575 billion plus or minus $200 million, a non-GAAP gross margin of 61.75% plus or minus 1 point, and non-GAAP diluted EPS of $0.99 plus or minus $0.10 on a split-adjusted basis (KLA 8-K, Apr 29, 2026). The company has confirmed it will report those results on July 28, 2026.
What are the risks for KLA?
- China and export controls. Evolving US Bureau of Industry and Security rules limit what KLA can sell and service in China, a large market for process-control tools, and further tightening would remove demand at short notice.
- Equipment cyclicality. Process control tracks the wafer-fab-equipment capex cycle, which has historically swung hard; a pause in customer spending would hit revenue across segments.
- Concentration and IP. A small number of leading-edge foundry, logic, and memory customers drive orders, and the business depends on defending inspection and metrology intellectual property against disputes.

Frequently asked questions about KLA
What does KLA Corporation do?
KLA makes semiconductor process-control systems: the inspection and metrology tools that find defects and measure critical dimensions during chip fabrication, plus process-enabling systems for specialty devices and printed circuit boards. Its Semiconductor Process Control segment was $3.08 billion, about 90% of fiscal Q3 2026 revenue (KLA 8-K, Apr 29, 2026). KLA is the dominant leader in process-control wafer-fab equipment.
What was KLA's latest quarterly revenue?
Fiscal Q3 2026 revenue (quarter ended March 31, 2026) was $3.42 billion, up about 11% year over year, with GAAP diluted EPS of $0.91 and non-GAAP EPS of $0.94 on a split-adjusted basis, and a GAAP gross margin near 61% (KLA 8-K, Apr 29, 2026). All per-share figures reflect the 10-for-1 stock split that took effect June 11, 2026 (KLA 8-K, Jun 2026).
What is KLA's guidance?
For fiscal Q4 2026, KLA guided revenue to $3.575 billion plus or minus $200 million, a non-GAAP gross margin of 61.75% plus or minus 1 point, and non-GAAP diluted EPS of $0.99 plus or minus $0.10 on a split-adjusted basis (KLA 8-K, Apr 29, 2026).
When does KLA report its next earnings?
July 28, 2026, a date KLA has confirmed: the company announced on July 1, 2026 that it will report fiscal fourth-quarter and full-year 2026 results on Tuesday, July 28, 2026, with a call at 2 p.m. Pacific time (KLA IR). It last reported fiscal Q3 2026 on April 29, 2026.
Why is KLA part of the silicon supply chain concept?
Because process control is the yield chokepoint of chipmaking. Every advanced wafer passes through inspection and metrology, and as geometries shrink toward gate-all-around and EUV and as advanced packaging adds failure modes, fabs depend on KLA to detect and measure defects that protect yield. KLA describes itself as a key enabler of the AI ecosystem across foundry/logic, memory, and advanced packaging (KLA 8-K, Apr 29, 2026).
