KLA Q3 FY2026 Hits $3.4B Revenue, Lifts WFE Outlook Above $140B as Advanced Packaging Revenue Heads to $1B

Headline Numbers

KLA Corporation reported fiscal third-quarter 2026 results on April 29, 2026, posting revenue of $3.415 billion — up 11% year over year and 4% sequentially — and non-GAAP diluted EPS of $9.40. Both figures came in above the midpoint of the company's prior guidance range of $3.35 billion ±$150 million in revenue.

GAAP net income per diluted share was $9.12. Service revenue reached $775 million, up 16% year over year. Cash flow from operations was $707.5 million, and free cash flow was $622.3 million in the quarter, contributing to roughly $4 billion of free cash flow over the trailing twelve months at a 31% FCF margin.

WFE Outlook Lifted Above $140B

Management raised its calendar 2026 wafer fab equipment (WFE) market forecast to "exceed $140 billion," up from the prior $135 billion to $140 billion range. The company said visibility into 2027 has continued to improve and that growth rates next year will surpass 2026.

The revision lines up with Lam Research's April 22 update, which also moved its 2026 WFE estimate to $140 billion with an upward bias. Two of the three largest process tool suppliers are now telling investors the same thing: capacity for advanced logic, HBM and advanced packaging is being absorbed faster than the equipment industry can ship.

Advanced Packaging Nearly Doubles to $1B

The standout disclosure was advanced packaging. KLA now expects its process-control revenue tied to advanced packaging to grow from approximately $635 million in calendar 2025 to roughly $1 billion in 2026 — a ~57% jump and a sharp upward revision from earlier estimates.

Inside that segment, advanced wafer-level packaging revenue grew about 70% year over year. Management said KLA picked up 14 percentage points of market share in advanced wafer-level packaging, attributing the gain to AI accelerator and HBM customers stacking more die per package and demanding tighter overlay, defect and film-thickness control across hybrid bonding, TSV and RDL layers.

Process Control Lead Widens

KLA said its overall process-control market share has grown by 360 basis points since 2021 and that it is now roughly seven times the size of its nearest competitor in the segment. The company's optical and e-beam inspection tools, overlay metrology and film metrology platforms are the de-facto standard at TSMC, Samsung Foundry, Intel Foundry and the leading memory makers.

Demand pull is strongest at 2nm and below, where gate-all-around transistors add approximately 50% more inspection layers and 30% more metrology layers versus FinFET. Backside power delivery, ramping at Intel 18A and at TSMC's A16 variant scheduled for the second half of 2026, creates a new through-wafer metrology category that didn't previously exist.

June-Quarter Guidance and Capital Returns

For the June 2026 quarter, KLA guided revenue of $3.575 billion ±$200 million, non-GAAP EPS of $9.87 ±$1, and GAAP EPS of $9.66 ±$1. Gross margin is forecast at 61.75% ±1 percentage point, with management noting a continuing roughly 100-basis-point headwind from elevated DRAM-related costs that will persist through calendar 2026.

The board approved a quarterly dividend increase to $2.30 per share starting with the May 2026 declaration, and authorized an additional $7 billion for share repurchases.

What This Means for Plasma Processing and Thin Film Deposition

KLA's process-control tools don't deposit or etch films — but their order book is the most reliable forward indicator that thin film deposition and plasma etch tools are shipping into fabs. Each new GAA logic layer, hybrid-bonded die stack and HBM4 base die brings additional ALD, CVD, PVD and PECVD steps, and every one of those steps needs film-thickness, composition and defect monitoring before the wafer can move to the next module. KLA's 50% inspection-layer increase and 30% metrology-layer increase at 2nm is a direct read on how much extra deposition is happening.

For plasma processing equipment, the advanced-packaging surge translates into more deep reactive ion etch (DRIE) for TSV and via formation, more plasma activation steps in hybrid bonding flows, and more PECVD for diffusion barriers, etch-stop layers and dielectric build-up. Hybrid bonding alone has moved from a niche application to a process flow that now requires sub-nanometer surface uniformity — and the inspection workload that comes with it.

For the broader equipment supply chain — plasma sources, sputter targets, vacuum components, gas delivery skids and process monitoring — the WFE outlook moving to "above $140 billion" with a positive bias for 2027 is the third consecutive upward revision from a top-five WFE supplier this earnings season. Customers building plasma chambers, RF generators, mass-flow controllers and high-purity yttrium-oxide chamber liners should plan for a continued lead-time-extended environment through next year.
