KLA (KLAC) Q2 2026 earnings review
Record Quarter Caps Record Year as AI Tailwinds Accelerate
KLA delivered an all-around record quarter with revenue of $3.30B (+7% YoY), beating guidance midpoint by $75M. Non-GAAP EPS of $8.85 exceeded expectations, driven by strong execution across all segments. Calendar 2025 was a banner year: record revenue, record non-GAAP operating income, and record free cash flow of $4.38B. The Semiconductor Process Control segment grew 9% YoY, fueled by AI infrastructure investment in leading-edge foundry/logic and HBM. Management struck a confident tone, positioning KLA as a key enabler of the AI ecosystem across all growth vectors. Q3 guidance calls for $3.35B revenue (+9% YoY at midpoint), signaling continued momentum.
🐂 Bull Case
KLA is uniquely positioned to benefit across all AI growth vectors: foundry/logic, memory (HBM), advanced packaging, and services. Process control intensity is structurally increasing as AI drives complexity, larger die sizes, and faster product cycles.
TTM free cash flow reached $4.38B with a 29% FCF margin. Capital returns totaled $3.01B over the past twelve months. The company has substantial firepower with $5.2B in cash and a $5B+ buyback authorization.
KLA continues to expand its dominant position in process control. Advanced packaging revenue is tracking to exceed $925M in CY2025, up ~70% YoY, with KLA on pace to become #1 in this market.
🐻 Bear Case
Export controls continue to weigh on results. Management previously quantified a $300-350M revenue impact through end of CY2026. China mix dropped from 39% in Q1 to expected mid-20s in coming quarters.
Global tariffs represent a 50-100 basis point structural headwind to gross margin. Q3 guidance implies gross margin of 61.75%, down from 62.5% in Q2, reflecting persistent cost pressures.
⚖️ Verdict: 🟢
Bullish. Record performance across all key metrics validates KLA's leadership position in enabling AI infrastructure. While China and tariff headwinds are real, they are manageable against the structural growth in process control intensity. Strong FCF generation and capital returns provide downside protection.
Key Themes
AI Infrastructure Remains the Primary Growth Catalyst
CEO Rick Wallace emphasized that KLA is 'a key enabler of the AI ecosystem' benefiting from buildout across foundry/logic, memory, advanced packaging, and services. The company's differentiated portfolio addresses the increasing relevance of process control at the leading edge. AI is driving larger die sizes, more complex designs, faster product cycles, and higher-value wafers—all of which increase demand for KLA's inspection and metrology tools.
Advanced Packaging Revenue Surging
Advanced packaging remains KLA's fastest-growing opportunity. Revenue is expected to exceed $925M in calendar 2025, up approximately 70% YoY. KLA estimates this is an $11B addressable market where the company is on track to be #1. The shift to heterogeneous integration for AI applications requires front-end-like inspection and metrology in back-end processes, playing directly to KLA's strengths.
HBM Driving DRAM Process Control Intensity
High-Bandwidth Memory production for AI applications is extremely process control intensive due to strict reliability requirements for stacked die. Management has noted that sensitivity requirements in some DRAM layers now exceed those in logic. DRAM is expected to be approximately 78% of memory revenue, with HBM driving an estimated 100-150 bps increase in DRAM process control intensity.
Services Business Provides Resilient Growth
Service revenue grew 18% YoY to $786M, marking another quarter of consistent outperformance. The services business has now delivered 52+ consecutive quarters of YoY growth. A growing installed base and higher-value service offerings in packaging and HBM support expected 12-14% growth in calendar 2026.
China Revenue Headwinds from Export Controls
U.S. export controls continue to constrain KLA's China business. Management previously quantified a $300-350M revenue impact through end of calendar 2026. China revenue mix, which peaked at 39% in Q1 FY26, is expected to decline to the mid-20s range going forward. This represents a structural reduction in addressable market, though capacity is expected to shift to other geographies over time.
Tariff Headwinds Pressuring Gross Margins
Global tariffs represent a persistent 50-100 basis point headwind to gross margins, primarily affecting the services business due to parts imports. While management is exploring mitigations through free trade zones and supply chain adjustments, this is being treated as a structural cost increase. Q3 gross margin guidance of 61.75% is down from 62.5% in Q2.
Broadening Leading-Edge Investment Beyond Single Customer
The expansion of advanced logic investment beyond the dominant foundry is creating incremental opportunities for KLA. More customers pursuing leading-edge nodes (2nm and below) in more geographies increases overall process control demand as new players benchmark requirements for successful ramp. Management has indicated this is visible in order forecasts.
RPO Disclosure Discontinued, Reducing Visibility
KLA stopped disclosing Remaining Performance Obligation (RPO) on a quarterly basis, citing inconsistency in industry reporting practices. While management states lead times have normalized to 7-9 months from a peak of 18 months, the loss of this forward-looking metric reduces investor visibility into demand trends.
Process Control Intensity Decoupling from Lithography
A key structural trend supporting KLA's outlook is the decoupling of process control intensity from traditional lithography intensity. Drivers include: proliferation of complex AI designs, larger die sizes, advanced packaging requirements, HBM complexity, and gate-all-around architectures. KLA's share of WFE at the 2nm node is projected to be 90-100 bps higher than at 3nm.
Other KPIs
Record trailing twelve-month free cash flow, up from $3.36B a year ago. FCF margin of approximately 29%. Quarterly FCF was $1.26B. This exceptional cash generation supports the company's aggressive capital return program while maintaining balance sheet strength.
Strong operating leverage continues. Q2 operating margin expanded from 43.2% in Q1 (Sept quarter). R&D increased 11% YoY to $384M as KLA continues investing in next-generation capabilities. SG&A was $280M, up 5% YoY. Operating income reached $1.33B.
Total shareholder returns of $797M in the quarter: $548M in buybacks and $250M in dividends. LTM capital returns of $3.01B represent 69% of free cash flow. The company maintains $5.2B in cash against $5.9B in debt with a strong investment-grade rating.
Core segment revenue grew to $3.00B from $2.76B a year ago. This segment represents 91% of total revenue. Growth was driven by leading-edge foundry/logic investment and strong HBM demand. PCB and Component Inspection was $152M (-6% YoY); Specialty Semiconductor Process was $141M (-12% YoY).
Guidance
Accelerating. Midpoint implies 9% YoY growth versus 7% in Q2. Sequential growth of 1.5% at midpoint. Guidance reflects continued momentum in AI-driven demand across foundry/logic and memory, partially offset by normalized China contribution.
Stable to Accelerating. Midpoint implies 11% YoY growth. Range of $8.30 to $9.86 reflects gross margin headwinds offset by operating leverage. Share count expected at 131.7M.
Decelerating slightly. Down 75 bps from Q2's 62.5%, primarily due to less favorable product mix and persistent tariff headwinds of 50-100 bps. GAAP gross margin guided at 60.62% +/- 1.00%.
Management is increasingly constructive that calendar 2026 will be a growth year for both WFE and advanced packaging. H1 2026 revenue expected flat to modestly up vs H2 2025, with growth accelerating in H2 2026. This outlook incorporates the $300-350M China headwind.
