Key Highlights

  • KLA reports fiscal Q4 and full-year fiscal 2026 results after the US close on Tuesday,; the newest reported period is the quarter.
  • June-quarter guidance: revenue of $3.575 billion plus or minus $200 million and non-GAAP diluted EPS of $8.87 to $10.87, pre-split.
  • Shares closed at $203.36 on July 27, roughly a third below the post-split 52-week high of $307.37.
  • Equipment spending is cyclical: KLA's fiscal 2024 revenue fell about 6.5%.

Why KLA Stock Is in Focus

KLA Corporation (NASDAQ:KLAC) supplies the inspection and metrology tools chipmakers use to find defects during manufacturing. Three things focus attention: Tuesday's fiscal year-end report, June's 10-for-1 split, and a sharp retreat from the highs. Market data providers put the close at $203.36, down 3.4% on the day, market capitalization near $265.6 billion and the 52-week range at $83.22 to $307.37.

The Latest Verified Development

KLA confirmed that it would review fourth-quarter fiscal 2026 earnings on Tuesday, July 28 at 2 p.m. Pacific time, publishing results after the close. They are not yet public, so the newest filed disclosure remains the quarter.

A May 8-K set the 10-for-1 split's record date at June 4, with split-adjusted trading from June 12. Any per-share figure dated earlier, including April's guidance, is pre-split.

Recent Financial Performance

Fiscal Q3 2026 revenue was $3.415 billion, up 11.5% year-over-year. GAAP net income was $1.201 billion and GAAP diluted EPS $9.12; non-GAAP net income was $1.239 billion and non-GAAP diluted EPS $9.40, both pre-split. GAAP gross margin was 61.2% and GAAP operating margin 41.5%. Management reported non-GAAP gross margin of 62.2% and non-GAAP operating margin of 42.6%.

Quarterly operating cash flow was $707.5 million and free cash flow $622.3 million; over twelve months, $4.402 billion and $4.015 billion. Nine-month fiscal 2026 revenue reached $9.922 billion. Fiscal 2025 revenue was $12.16 billion, GAAP diluted EPS $30.37, non-GAAP $33.28.

What Management Has Guided

For fiscal Q4 2026, KLA guided revenue to $3.575 billion plus or minus $200 million, GAAP gross margin to 59.72%-61.72% and non-GAAP to 60.75%-62.75%. GAAP diluted EPS was guided to $8.66-$10.66 and non-GAAP to $8.87-$10.87, pre-split; dividing by ten gives roughly $0.89-$1.09 post-split.

The midpoint implies about 12.6% growth against the $3.175 billion of June 2025. CFO Bren Higgins guided foundry and logic to roughly 82% of process control systems revenue, memory to 18%, and DRAM to about 84% of memory.

Business Model and Principal Assets

Of three reportable segments, Semiconductor Process Control produced $3.084 billion of fiscal Q3 revenue, about 90% of the total; Specialty Semiconductor Process contributed $164.0 million and PCB and Component Inspection $167.6 million. Wafer inspection alone was $1.740 billion, patterning $615.1 million.

Services revenue was $774.8 million, up 16% year-over-year and roughly 23% of the quarter; the FY2025 10-K puts services near 22% of that year's revenue under contracts that extend system lifetimes. That stream follows the installed base rather than new orders, damping cyclicality.

Process Control and AI Chip Complexity

KLA states that its share of process control has grown 360 basis points since 2021 and is roughly seven times the nearest competitor's, with company materials citing a share near 58%.

CEO Rick Wallace argued in April that intensity is not driven by lithography alone: "The 2-nanometer node has higher intensity than 3-nanometer node and the amount of EUV layers hasn't changed all that much from node to node." One reading is that architectural change, gate-all-around transistors, larger dies, stacked packaging, raises the number of steps requiring measurement. That is inference from company assertions, not audited share data.

Customer Concentration

The March 2026 10-Q discloses one customer at 19% of quarterly revenue and a second at 11%; across the nine months the largest was 17%, against 20% a year earlier. The FY2025 10-K names Taiwan Semiconductor Manufacturing Company above 10% of revenue in fiscal 2025, 2024 and 2023, and Samsung Electronics in fiscal 2023. At that level, one customer's spending deferral can move a quarter.

China Exposure and Export Restrictions

China was 24.3% of fiscal Q3 2026 revenue at $829.6 million, behind Taiwan at 25.5% and ahead of Korea at 19.9%; across the nine months it was 31.2%. The FY2025 10-K records China at 33% of revenue, down from 43% in fiscal 2024.

The regulatory position is live. In August 2025 the Bureau of Industry and Security revoked Validated End-User authorizations for foreign-owned fabs in China, requiring licences and signalling no approvals for capacity expansion or technology upgrades. The Entity List "affiliates rule" was suspended effective recently and reinstates absent extension. In April 2026 Commerce told equipment makers including KLA to halt certain shipments to Hua Hong; Higgins called the guidance impact "fairly immaterial."

Competitive Position

The FY2025 10-K names Applied Materials, ASML Holding, Hitachi High-Technologies, Onto Innovation and Lasertec as principal competitors. Overlap differs by product: Applied Materials and Hitachi in e-beam and defect review, Onto Innovation in optical metrology and packaging inspection, Lasertec in mask and EUV blank inspection. ASML and Lam Research are larger suppliers that compete only at the margins. KLA is strongest in optical patterned-wafer inspection.

Growth Opportunities

Management raised its 2026 wafer fab equipment view above $140 billion, and expects process control revenue from advanced packaging to rise from about $635 million in 2025 to roughly $1 billion in 2026. The March 2030 model assumes an 11% semiconductor industry CAGR, a wafer equipment market of $215 billion plus or minus $20 billion, a KLA revenue CAGR objective of 13%-17% and services growth of 13%-15%, targets, not verified forecasts.

Balance Sheet, Free Cash Flow and Capital Returns

KLA held $1.787 billion in cash and $3.171 billion in marketable securities against $5.887 billion of long-term debt. The March quarter brought $248.8 million of dividends and $626.0 million of buybacks; over twelve months, $1.006 billion and $2.144 billion, or about 78% of free cash flow by this calculation. In March it authorized $7 billion of repurchases atop $3.944 billion remaining and raised the quarterly dividend 21% to $2.30 pre-split, a seventeenth straight annual increase.

Valuation and Investor Expectations

On July 27 data, KLA traded at a trailing P/E near 57.6 and a forward P/E near 42.3, with price-to-sales of 20.3, EV/revenue of 20.4 and EV/EBITDA of 45.6. Trailing free cash flow of $4.01 billion against the $265.6 billion market capitalization implies a free-cash-flow yield near 1.5%. These are aggregator figures, not filings, and multiples move continuously; they imply shares embedding multi-year execution against the 2030 targets.

Cyclicality and Risks to the Thesis

Equipment spending is cyclical: KLA's fiscal 2024 revenue fell about 6.5%. Higgins flagged elevated DRAM costs in KLA's own image-processing computers as roughly a 100 basis point gross-margin headwind over several quarters, memory inflation cuts both ways. Other risks include the November 2026 affiliates-rule reinstatement, further shipment-halt letters, customer concentration near 19%, and a valuation leaving little tolerance for a guidance miss.

Conclusion

Tuesday's report will show whether the June quarter landed inside the guided band and, more consequentially, what management says about calendar 2026 equipment spending and gross margin. The operating record is strong: high-30s to low-40s operating margins, disciplined capital returns and a defensible niche. The open questions are cyclical timing, China licensing and price, best judged from the filings and disclosed guidance rather than the past year's share price path.
