Expected to continue to grow given the order funnel.

Risks & headwinds

Memory pricing environment and tariff headwinds through 2027

approximately 100 basis points impact on gross margin

Mitigation:Expects normalization on the pricing front to move from a headwind to a tailwind in 2027; new products allow for cost structure changes and pricing adjustments.

Operating expense growth next several quarters

grow by roughly $15 million to $20 million sequentially over the next several quarters

Mitigation:Prioritizing next-generation product development and company infrastructure investments to support expected revenue growth; business model designed to deliver 40-50% incremental operating margin leverage on revenue growth.

Supply chain shortages for long lead time materials H1 CY26

impacted in the first half (CY26)

Mitigation:Supply is coming online in the second half (CY26); actively engaging with critical suppliers and planning capacity agreements for 2029 and beyond.

What to watch in Q1 FY27

Gross Margin Trajectory

CY27
Current 62.5% +/- 1% (September quarter guidance)
Target Continued improvement, normalization of memory pricing headwinds

Why it matters

Gross margin trajectory is key to profitability, especially with ongoing memory pricing and tariff headwinds.

We talked about 2026 overall gross margins likely being in the 62%, plus or minus. Clearly, if you look at the guidance we provided expectations for next quarter, we're going to be above that. So we feel pretty good from a trajectory point of view.

Q&A highlights

How should we think about the trajectory for gross margins into '27 and '28, considering new supply, mix shift to tools, and passing on inflation?

Gross margin is benefiting from leverage but still faces a ~100bps headwind from memory pricing and tariffs, which is expected to continue into 2027 before normalizing. New products allow for cost structure changes and pricing adjustments. The company expects to operate within its 60-65% incremental gross margin model.

Detailed narrative

AI Infrastructure Expansion Driving Demand

KLA is uniquely positioned on the critical path of AI infrastructure expansion, with AI-driven design activity and HBM adoption increasing demand for process control. The rapid expansion of the AI ecosystem requires more advanced logic and memory, new complex manufacturing and packaging flows, and additional KLA systems and services to ramp, yield, and sustain high-volume production.

Demand signals across AI infrastructure have strengthened materially, supported by accelerating hyperscale data center investment and broader AI-enabled application adoption.

Accelerated Advanced Packaging Momentum

Advanced packaging process control systems revenue is accelerating, expected to reach approximately $1.1 billion in calendar 2026, representing over 70% year-over-year growth. This significantly exceeds the prior expectation of high 50% growth and is almost twice as fast as the advanced packaging market.

This growth is driven by faster product cycles, higher-value wafers and masks, more rigorous device performance specifications, and the adoption of new technologies like hybrid bonding.

Orbotech Acquisition Thesis Validation

The 2019 Orbotech acquisition, centered around the rising value of the chip package, is proving successful. Combined products from this acquisition, including Specialty Process, PCB, and Component Inspection businesses, are expected to grow over 25% in calendar 2026. This momentum is augmented by high-performance compute packages and integration, demonstrating KLA's ability to drive product strategy and business execution in evolving markets.

Strengthening WFE Outlook and Visibility

KLA raised its calendar 2026 wafer equipment market outlook to the low $150 billion range, up from $140 billion+, reflecting accelerating customer delivery expectations and strengthening demand across all segments. The company has unprecedented visibility into calendar 2027, with broad-based investment across leading-edge logic, foundry, DRAM (conventional and HBM), NAND, and advanced packaging driving continued capacity expansion.

This sets the stage for significant growth in 2027.

Robust Process Control Competitive Moat

KLA maintains a strong competitive position in process control due to its integrated technologies, deep customer engagement, and extensive applications engineering support, with 1,600-1,700 engineers worldwide. This expertise, combined with a focus on high-mix, low-volume markets and advanced algorithms, creates a significant competitive moat. The company's ability to help customers accelerate yield learning and improve productivity makes its offerings difficult for competitors to replicate.

Proactive Capacity Expansion and Supply Chain Management

KLA is actively adding capacity and engaging with critical suppliers for long-lead-time materials, planning for needs into 2029 and beyond. This proactive approach aims to support expected demand and ensure the company can meet more bullish market scenarios. Despite some supply chain shortages impacting first-half calendar 2026 shipments, KLA expects supply to come online in the second half, enabling accelerated growth.
