StockStory’s take

KLA Corporation’s third quarter results were marked by strong demand for semiconductor process control equipment, with management attributing the outperformance to surging investment in artificial intelligence (AI) infrastructure and advanced packaging technologies. CEO Richard Wallace emphasized that “KLA’s performance in the quarter was supported by continued strength in leading edge foundry logic related to AI infrastructure investments, and increasing process control intensity across leading edge devices and advanced packaging.” The quarter also benefited from increased customer engagement, a growing backlog, and robust execution in the company’s services business, reflecting KLA’s close alignment with customer technology roadmaps and the rising complexity of semiconductor manufacturing.

Looking ahead, management pointed to accelerating demand for advanced semiconductor manufacturing as a key driver of next quarter’s growth outlook, particularly in AI, high bandwidth memory, and advanced packaging applications. CFO Bren D. Higgins stated the company’s supply chain investments have positioned KLA to support “sequential growth for the next several quarters,” while highlighting that new fab projects and greenfield facilities will further broaden growth opportunities. The company also expects improvements in product mix and pricing to contribute to margin performance as it continues to optimize its manufacturing and supply chain capabilities to meet elevated customer demand.

Key insights from management’s remarks

Management highlighted that robust demand for AI and advanced packaging technology, combined with operational execution and growing services revenue, were central to the quarter’s performance and improved outlook.

• AI infrastructure momentum: KLA saw increased demand from leading edge foundry and logic customers investing in AI and high-performance computing, which drove higher process control intensity and contributed to backlog growth.
• Advanced packaging surge: Revenue from advanced packaging process control systems is on track to reach $1.1 billion for the year, with over 70% growth—almost double the market rate—reflecting the technology’s expanding role in AI data centers and complex chip designs.
• Service business expansion: The company’s services segment grew 14% year-over-year, fueled by a larger installed base and higher tool utilization rates, as customers prioritized equipment performance and uptime amid tight manufacturing environments.
• Supply chain investments: KLA continued to work closely with strategic suppliers to expand capacity, particularly for critical optical and memory components; this has enabled the company to keep pace with demand and support future revenue growth.
• Margin improvement: For the first time, operating margins exceeded 46%, driven by a combination of manufacturing scale, improved product mix, and ongoing efforts to optimize memory usage and system efficiency.

Drivers of future performance

KLA’s management forecasts sustained growth, supported by continued AI-driven demand, advanced packaging expansion, and operational leverage, though supply chain and input cost challenges remain key factors.

• AI and advanced packaging demand: Management expects ongoing strength in AI infrastructure and advanced packaging to drive sequential revenue growth, with new fab investments and technology transitions expanding KLA’s addressable market through 2027.
• Operational leverage and cost controls: The company plans to maintain high incremental operating margin by managing expense growth below expected revenue gains, while cost optimization initiatives—especially in memory usage—aim to offset persistent input cost headwinds.
• Supply chain risks and capacity: While KLA’s investments have improved supply reliability, management cautioned that long lead times for components and potential customer delays in facility readiness could influence the timing of revenue recognition and overall growth trajectory.

Catalysts in upcoming quarters

Over the coming quarters, the StockStory team will watch for (1) ongoing strength in AI and advanced packaging demand, (2) the pace at which KLA’s supply chain investments translate into higher shipment volumes, and (3) the impact of product mix and cost optimization on operating margins. Execution in expanding capacity, as well as the company’s ability to support customer ramp schedules and manage input cost pressures, will be critical milestones.

KLA Corporation currently trades at $164.00, up from $158.53 just before the earnings. At this price, is it a buy or sell? See for yourself in our full research report (it’s free).
