For the to-be-reported quarter, KLAC expects revenues of $4 billion, plus/minus $200 million. The Zacks Consensus Estimate for revenues is pegged at $4.05 billion, indicating an increase of 26.09% from the year-ago quarter’s reported figure.
For the fiscal first quarter, non-GAAP diluted earnings are projected at $1.16 per share (plus or minus 10 cents). The consensus mark for earnings is pegged at $1.18 per share, unchanged over the past 30 days, indicating year-over-year growth of 34.09%.
KLAC’s earnings have surpassed the Zacks Consensus Estimate in all the trailing four quarters, the average surprise being 2.75%.
Let us see how things have shaped up for the upcoming announcement.
Key Factors to Note Ahead of KLAC’s Q1 Results
KLA's first-quarter fiscal 2027 results are expected to have benefited from accelerating investments in artificial intelligence (AI) infrastructure, particularly advanced semiconductor manufacturing. Increasing demand for AI processors, high-performance computing chips and sophisticated semiconductor designs is driving the adoption of KLA’s inspection and metrology solutions. The transition toward 2-nanometer manufacturing and gate-all-around transistor architectures is increasing process control requirements. The company's Semiconductor Process Control business is expected to have benefited from these trends in the to-be-reported quarter.
Increased investments in DRAM manufacturing, particularly high-bandwidth memory (HBM) used in AI accelerators and data centers, are expected to have driven top-line growth in the fiscal first quarter. Growing HBM adoption, increasing extreme ultraviolet (EUV) lithography applications and rising memory-device complexity are creating additional demand for process control equipment. HBM’s larger die sizes, stringent performance specifications and complex stacking architectures require more sophisticated inspection and metrology capabilities. These factors bode well for KLAC.
Moreover, fiscal first-quarter results are expected to have benefited from robust demand for advanced packaging solutions, supported by growing adoption of heterogeneous integration, chiplets and high-performance computing architectures. Increasing packaging complexity is encouraging semiconductor manufacturers to deploy more advanced inspection and metrology tools to improve yields and manufacturing efficiency. KLA expects its advanced packaging process control systems revenues to reach approximately $1.1 billion in calendar 2026, indicating growth of more than 70% year over year. The company is also witnessing growing adoption of its front-end inspection technologies in advanced packaging manufacturing.
Meanwhile, fiscal first-quarter results are also expected to reflect improving component availability and expanding manufacturing capacity. KLA expects revenues in the second half of calendar 2026 to increase approximately 20% from the first half, reflecting accelerating customer demand and improving supply chain execution. Strong equipment orders and a backlog of approximately $12.57 billion at fiscal 2026-end are providing substantial revenue visibility.
Nevertheless, KLAC management has highlighted that calcium fluoride optical components can have lead times of 18-24 months or longer, potentially limiting production flexibility. Rising memory prices have also pressured gross margins, with the company indicating a negative impact exceeding 100 basis points in recent quarters.
KLAC Shares Outperform Sector & Peers
KLA shares have returned 21.6% year to date (YTD), outperforming the broader Zacks Computer and Technology sector’s return of 18%. However, the company has underperformed peers, including Applied Materials (AMAT - Free Report) , Teradyne (TER - Free Report) and Axcelis Technologies (ACLS - Free Report) , YTD. Shares of Applied Materials, Teradyne and Axcelis have returned 46.1%, 58.2% and 30.3%, respectively, over the same timeframe.

KLA’s Prospects Ride on Strong Advanced Packaging Growth
KLA’s advanced packaging business represents a significant long-term growth opportunity as semiconductor manufacturers increasingly adopt chiplets, heterogeneous integration and advanced packaging architectures. The company expects KLA’s share of the advanced packaging market to increase to approximately 7-8% in 2026 from only a few percentage points in 2023. The increasing application of front-end manufacturing processes in advanced packaging is driving demand for more sophisticated inspection and metrology solutions. Growing adoption of hybrid bonding and high-density interconnect technologies should further expand KLA’s addressable market.
The company is well-positioned to capitalize on increasing wafer fabrication equipment (WFE) spending, supported by AI infrastructure investments, semiconductor capacity expansion and technology transitions. The company raised its calendar 2026 WFE market outlook to the low-$150-billion range, representing mid-20% growth from approximately $120 billion in 2025. KLAC management indicated that industry growth in 2027 could match or exceed 2026 levels, with a scenario approaching $190 billion in WFE spending.
KLA’s growing installed equipment base is expected to support sustained expansion in its services business. The company has established a long-term annual services revenue growth target of 13-15%, supported by increasing equipment installations, maintenance requirements, upgrades and productivity-enhancing solutions. Approximately 80% of services revenues are contract-based, providing recurring revenue visibility. Strong equipment shipments in calendar 2026 and 2027 should expand the installed base, creating additional opportunities for service contracts and customer support.
Conclusion
KLA’s strong positioning in the semiconductor process control market, accelerating AI infrastructure investments and robust demand for advanced packaging solutions bode well for its growth prospects. Increasing process control intensity, rising HBM adoption and expanding WFE spending are expected to sustain revenue momentum. A strong backlog and growing services business further strengthen its long-term outlook.
