I'll research KLAC thoroughly before writing the preview. Let me start by gathering recent earnings materials, guidance, and news.The stock has been extremely volatile — let me dig into the most recent quarter's results, guidance, and management commentary.Let me get recent news context, including the sharp July pullback and any peer/macro developments.I now have what I need. Let me write the preview.
KLA reports into a market that has fallen wildly in and out of love with it in the span of eight weeks. The stock was on pace for its best month in almost 40 years at the end of June, up around 150% this year—the most since 1999, with the rally reflecting South Korea's over $500 billion investment in AI chip production and plans by Samsung and SK Hynix to build chip plants. Since that June 30 peak (~$302), the shares have retraced roughly a third, closing at $203.40 on July 27. The print itself should be a formality — the real event is what management says about calendar 2027, and whether the sudden late-July "China self-sufficiency" scare has any teeth.
The June quarter is essentially pre-announced by guidance. Management guided FQ4 to:
Street is essentially sitting on the guide. KLAC is scheduled to report fourth-quarter earnings on July 28 after the close, with sentiment very bullish, and Street expectations for FQ4 include sales growth of +13.5% to $3.6B with gross margins of 61.75%. (Note: the news wire's "$1.00 EPS" figure is garbled — consensus tracks the ~$9.90 guide.)
For context, KLA has been beating and raising all year. Last quarter: revenue of $3.415 billion, up 4% sequentially and 11% year-over-year, above the guidance midpoint of $3.35 billion, with non-GAAP diluted EPS of $9.40, both above the midpoints. Gross margin was 62.2%, 45 basis points above the midpoint of guidance. A midpoint print + modest raise is the base case; the bar, given the run, is arguably a beat-and-raise with an emphatic 2027 message.
Management has repeatedly framed the business around calendar years, and the tone last quarter was the most bullish in memory:
The framing math investors are working with: high-teens growth gets calendar 2026 revenue into the ~$15 billion range, with roughly 15%–20% second-half-over-first-half growth. Watch whether the exit rate (September-quarter guide) confirms that back-half acceleration.
CEO Rick Wallace's demand commentary was unusually forceful, and worth re-reading given the current "AI capex durability" debate: even with very aggressive plans through 2026 and 2027, customers are not going to close the gap, and in some cases the gap has expanded — so you cannot draw a straight line from hyperscaler capex to WFE because the industry is way underserving that demand. He also pushed back directly on the idea that a soft hyperscaler capex quarter matters near-term, arguing the constraint is physical fab capacity, not order intent.
Key question for the call: Do they put a number on 2027 WFE/KLA growth, or hold at "higher than 2026"? A hard framework here is the single biggest potential catalyst.
This is the segment that keeps getting revised up, and it's directly levered to HBM/AI:
Given CoWoS/SoIC and hybrid-bonding demand, another upward revision here would be a positive surprise.
The margin story is a tug-of-war between volume/scale (positive) and memory-input costs + tariffs (negative):
Ironically, the very memory shortage driving KLA's revenue is also inflating its input costs. Note the reassurance that supply is locked: management feels very good about the supply situation to support build plans through next year. Watch for any change to the ~62% CY26 anchor.
The late-July selloff wasn't KLA-specific; it was a sector re-rate on China indigenization fears. Chip stocks reversed sharply lower following a massive Chinese IPO and a report that a state-backed Chinese company has started mass producing chip-making machines, with ASML falling 6–8% after Bloomberg reported the Chinese immersion DUV production capability. Separately, memory-maker CXMT completed a nearly $10 billion IPO — the biggest mainland listing in years — after a first-half net income increase of more than 2,200% driven by surging chip prices, while avoiding the stricter U.S. Commerce Department entity list and preserving access to U.S. technology.
KLA's own China framing has been consistently measured: overall spending in China has been fairly flat over the last few years, and KLA expects the China growth rate to be lower than the overall WFE growth rate going forward, with leading-edge driving the business. On the Hua Hong export restriction: management said the impact on Q2 guidance and 2026 commentary is fairly immaterial and already contemplated in guidance. Expect a pointed analyst question on whether Chinese DUV/CXMT progress changes the long-term China revenue trajectory; a confident, "no near-term impact" answer is the bull case, any hedging is the risk.
KLA's model throws off cash and returns nearly all of it: quarterly free cash flow was $622 million and trailing-twelve-month free cash flow was $4 billion, a 31% free cash flow margin. Total capital returned in the March quarter was $875 million ($626M buybacks, $249M dividends), and $3.2 billion over the trailing twelve months. At the March Investor Day, KLA announced its 17th consecutive quarterly dividend increase and an incremental $7 billion repurchase authorization, and raised its capital allocation target to over 90% of free cash flow. The dividend steps up to $2.30 per share beginning with the dividend expected to be declared in May 2026.
The long-term model to hold management to: a revised 13%–17% revenue CAGR objective through 2030, assuming a baseline semiconductor industry growth CAGR of 11% and the wafer equipment market growing to $215 billion +/- $20 billion by 2030.
Fundamentally, KLA goes into this print with about as strong a demand backdrop as it has ever described, best-in-class margins and cash returns, and rising process-control intensity across foundry/logic, memory, and advanced packaging. The risk is not the numbers — it's expectations and the tape: a stock that ran ~150% and then gave back a third, a freshly nervous market on AI-capex returns and Chinese equipment indigenization, and a "high bar" that likely requires a beat-and-raise plus a confident, quantified 2027 message to be rewarded. A clean in-line print with cautious 2027 language could still see the stock sold; the upside case is management putting a hard number on 2027 acceleration and nudging up the advanced-packaging and margin outlooks.
