KLA (KLAC) Q1 2026 earnings review
AI Demand Fuels Record Quarter, But New China Export Controls Cloud 2026 Outlook
KLA delivered strong Q1 results, beating guidance with revenue of $3.21 billion and non-GAAP EPS of $8.81, driven by robust investment in AI infrastructure, High-Bandwidth Memory (HBM), and advanced packaging. The company's advanced packaging business is a standout, now forecast to grow 70% YoY to over $925 million in CY25. However, the positive operational story is tempered by new U.S. export controls, which are expected to create a $300-$350 million revenue headwind through calendar 2026. Guidance for Q2 is stable sequentially but implies a sharp deceleration in YoY growth, signaling that peak growth rates are moderating.
🐂 Bull Case
The AI infrastructure buildout is fueling demand across leading-edge logic, HBM, and advanced packaging. KLA's packaging business is on track to exceed $925M in CY25 (+70% YoY), emerging as a powerful new growth driver.
Increasingly complex chips (GAA, HBM) require more inspection and metrology, structurally increasing KLA's share of wafer fab equipment spending and allowing the company to consistently outperform the overall market.
🐻 Bear Case
Recently expanded U.S. export controls are expected to reduce revenue by $300-$350 million through the end of calendar 2026, creating a significant hole to fill from a region that represented 39% of sales this quarter.
Q2 guidance implies YoY revenue growth will slow to just 4.8% from 13.0% in Q1. This sharp deceleration suggests the period of strongest growth is over, and the business is normalizing to a more modest trajectory.
⚖️ Verdict: 🟢
Bullish. While the new China export controls create a headwind and growth is decelerating from high levels, the underlying secular drivers in AI, HBM, and advanced packaging are powerful and durable. The company's ability to outperform the broader WFE market and its strong cash generation provide a solid foundation to navigate the geopolitical uncertainty.
Key Themes
Advanced Packaging Becomes a Core Growth Engine
KLA's advanced packaging business has emerged as a major growth vector, with CY25 revenue now forecast to exceed $925 million, a ~70% YoY increase. This growth is driven by the complexity of heterogeneous integration for AI chips, where the high value of the final package justifies using KLA's high-end front-end tools. Management noted this is a new served available market for the company, augmenting its core WFE growth.
New China Export Controls Create Revenue Headwind
Management quantified a direct revenue impact of $300 million to $350 million through the end of calendar 2026 due to expanded U.S. export controls. This creates a significant challenge, as China represented 39% of total revenue in Q1. The company expects the China revenue mix to fall to the high 20s in Q2 and normalize to the mid-20s in CY26.
Rising Process Control Intensity in AI and HBM
The shift to AI workloads is structurally increasing demand for process control. Management highlighted that High-Bandwidth Memory (HBM) production requires higher intensity due to larger die sizes, stacking complexity, and stringent reliability requirements, since a single bad die can ruin the entire component. Similarly, the transition to Gate-All-Around (GAA) logic at the 2nm node is more process control-intensive than prior nodes.
Growth Profile is Decelerating
After a year of 20-30% YoY growth, KLA's trajectory is clearly moderating. The Q2 revenue guidance midpoint of $3.225B implies just 4.8% YoY growth, a sharp slowdown from Q1's 13.0%. This indicates that the company is moving past its peak growth phase and into a period of more normalized, single-digit expansion, compounded by the new China restrictions.
Resilient Services Business Delivers Stable Growth
The services business continues to be a consistent performer, growing 16% YoY to $745 million in the quarter. This highly profitable, recurring revenue stream provides a stable foundation for the company, supported by a large and growing installed base of tools that require ongoing maintenance and upgrades.
Specialty Semiconductor Process Segment in Decline
While small, the Specialty Semiconductor Process segment is a lagging part of the portfolio. Revenue declined 6.7% YoY to $119.8 million this quarter. This contrasts with strong growth in the main Semiconductor Process Control (+12.6% YoY) and PCB/Component Inspection (+37.3% YoY) segments, acting as a slight drag on overall results.
Other KPIs
KLA's business model continues to be a powerful cash generator, producing $1.07 billion of free cash flow in Q1 and $3.9 billion over the last twelve months. This robust cash flow easily funds the company's R&D investments and significant capital returns to shareholders.
The company returned $799 million to shareholders in Q1, comprising $545 million in share repurchases and $254 million in dividends. Supported by a new $5 billion repurchase authorization announced last quarter, KLA continues to demonstrate confidence in its long-term outlook through aggressive capital returns.
Guidance
Decelerating. The midpoint implies 4.8% YoY growth, a significant slowdown from 13.0% in Q1. Sequentially, revenue is guided to be roughly flat (+0.5%), reflecting a stable but maturing demand environment.
Decelerating. The midpoint suggests 6.1% YoY growth, down from 20.2% in Q1. Sequentially, EPS is expected to decline slightly from $8.81, reflecting stable gross margins but slightly higher operating expenses.
Reversing. This represents a major shift toward Memory, which was guided to be only ~25% of the mix two quarters ago. Management attributes the change to a decrease in China-related logic sales and an increase in DRAM/HBM investment.
