KLA Corporation's fiscal first-quarter EPS was no surprise. Non-GAAP earnings of $1.22 per share matched the Earnings Whisper number exactly and topped the $1.18 consensus. The forward picture is what changed. Revenue of $4.136 billion beat consensus by 2.1% and rose 28.9% year over year. Earnings grew 38.5%. December-quarter guidance of $4.7 billion (+/- $200 million) and non-GAAP EPS of $1.44 (+/- $0.11) points to another sharp sequential step. The guide implies roughly 13% sequential revenue growth on top of a September quarter that itself grew about 13% from June's $3.66 billion. June had grown about 7% from March's $3.415 billion. The quarter that met expectations sits under an outlook that is accelerating.

The headline numbers hold up to scrutiny, with a few caveats. Operating margin hit a record 46.1%, up 240 basis points sequentially. Free cash flow jumped to $1.34 billion from $817 million in June. That rebound partly reflects a lighter receivables build after June's large swing. Product revenue rose to $3.29 billion from $2.84 billion. Semiconductor Process Control drove nearly all of the gain, climbing to $3.75 billion from $3.26 billion. Specialty Semiconductor Process slipped sequentially, and PCB and Component Inspection was flat. GAAP EPS of $1.18 trailed non-GAAP by only four cents, so adjustments are not flattering the story. One item was new: the GAAP tax rate climbed to about 15% from roughly 12% in June. That increase includes $20 million of Pillar Two taxes that management expects to reverse. Inventory grew by $442 million to $4.09 billion and capex roughly doubled to $195 million. Both moves fit a company building for higher shipments, but they are worth monitoring.

The conference call is where the investment case strengthened. Management raised its calendar 2026 wafer-fab-equipment view for the fourth straight time, to the mid-$150 billion range. The trail runs from mid-$130 billion in January, to above $140 billion in April, to low-$150 billion in July. KLA also offered its first explicit 2027 framework: WFE above $200 billion, growth of roughly 30% or more. In July the company had framed about $190 billion. Second-half 2026 growth over the first half is now about 25%, up from about 20% in July and only high-single to low-double digits in January. Memory is the swing factor. It should account for roughly 40% of semi process control systems in the December quarter, up from the 27% guided for September. Management expects memory to be about 60% of 2027 WFE, with DRAM greenfield builds and process-control intensity approaching leading-edge logic. Advanced packaging process control is tracking near $1.1 billion for 2026, up about 70%. Management said its 2030 model assumptions will be exceeded before 2030 and expects sequential growth for several more quarters.

Bears still have legitimate ammunition, and most of it concerns margins and execution rather than demand. Gross margin was 62.7%, and the December guide is flat at 62.5% despite double-digit revenue growth. That remains below the 63-64% target, as DRAM component costs and mix from advanced packaging and non-semi businesses absorb operating leverage. Services growth slowed to 14% year over year from 17%. Lead times have stretched to about 12 months and longer for Gen4 and Gen5 tools. KLA remains supply constrained, and some deliveries are on hold because customer cleanrooms and power are not ready. Spending is rising on several fronts:

• December-quarter opex should rise to about $710 million.
• Capex is heading toward $600-800 million annually, including a new campus in India.
• China's revenue share is expected to fall to the low-20s percent in 2027.

The market setup is more complicated than the fundamentals imply. Shares closed at $153.66 on the eve of the report, down 13.5% from the open after July's release. They sat 15.4% below the 200-day moving average and 28.5% below the August 13 high of $214.80. The stock had touched a $144.82 low just days earlier. Investor sentiment slipped from modestly positive (0.13) to essentially neutral, so expectations were reset rather than stretched heading into the print. The Earnings Whispers trend readings are split. Sequential growth and momentum are positive, while price and AVWAP trends remain negative.

The bottom line is that KLA delivered an in-line quarter wrapped around a materially better outlook. Its industry forecasts keep rising, a record operating margin and a $200 billion-plus 2027 WFE view extend the growth runway, and a weak stock has deflated sentiment. The flat gross-margin guide, supply constraints, and customer readiness delays are the real watch items. Investors now have to weigh accelerating demand against how much of that growth reaches the bottom line.
