KLAC · KLA

The thesis

KLA Corporation's shares are modestly more likely to beat the S&P 500 over the next three months. KLA beat its September-quarter guidance and raised its outlook on 28 October 2026, and Applied Materials' results on 12 November 2026 show chip-equipment demand holding through the sector selloff. KLA's December-quarter report, expected around 28 January 2027, settles whether revenue reaches the $4.7 billion guide.

KLA reported revenue of $4.136 billion for the quarter ended 30 September 2026, against guidance of $4.0 billion plus or minus $200 million (earnings release, 28 October 2026). The shares then fell with the chip sector to a close of $129.80 on 5 November 2026 and recovered to $157.30 on 12 November 2026. That close sits below every target analysts published after the report, including UBS's $180 and Susquehanna's $190 (29 October 2026). The price reflects doubt that 2026's growth carries into 2027 more than doubt about the December quarter.

The rating is modestly better than even odds. Company and peer results support the December guide. Against that, the shares trade below their 50-day and 200-day moving averages, and the sector has shown it can fall 12% in a day.

Bullish and bearish views on KLA Corporation

The bull case on KLA Corporation (KLAC), in brief: the quarter beat on every guided measure. The bear case: the trend is still down.

Bull case

• The quarter beat on every guided measure. Revenue was $4.136 billion and adjusted earnings were $1.22 per share, both above the midpoints of KLA's guidance (earnings release, 28 October 2026). Free cash flow was $1.34 billion and stock repurchases $935.8 million in the quarter.
• The December outlook was raised. KLA guided December-quarter revenue to $4.7 billion plus or minus $200 million, adjusted gross margin to 62.5% plus or minus 1 percentage point and adjusted earnings to $1.44 per share plus or minus $0.11. It said second-half calendar 2026 revenue should grow about 25% over the first half, up from about 20% guided in July (earnings release and call, 28 October 2026).
• Applied Materials confirmed demand on 12 November 2026. Applied reported fiscal fourth-quarter revenue of about $10.4 billion, up 53% from a year earlier, and adjusted earnings of $4.16 per share against $4.06 expected (investingLive, 12 November 2026). It guided the first quarter of fiscal 2027 to $11.1 billion plus or minus $500 million, against about $10.7 billion expected, and its shares rose about 1.5% after hours, according to Investing.com via MLQ.ai.
• Memory makers are buying more tools. Dynamic random-access memory (DRAM) equipment was 33% of Applied's semiconductor systems sales in its fiscal fourth quarter, up from 28% a year earlier (MLQ.ai, 12 November 2026).
• The order book backs the guide. Backlog was $12.57 billion at 30 June 2026, up from about $7.86 billion a year earlier (fiscal 2026 Form 10-K).
• Post-report targets sit well above the close. Citigroup kept Buy with a $275 target, Stifel Buy at $230 and Wells Fargo Overweight at $210 on 29 October 2026; Argus reiterated Buy at $225 on 30 October 2026.

Bear case

• The trend is still down. The 12 November 2026 close of $157.30 is below the 50-day average of $173.41 and the 200-day average of $181.62, and the three-month price change is negative 22.7% (adjusted daily closes).
• Sector selloffs override company results. Chip stocks had their worst day since March 2020 on 5 November 2026, with the iShares Semiconductor exchange-traded fund down about 12% (247WallSt, 6 November 2026). A 9 November 2026 headline put chip stocks 38% below their peak.
• China is a shrinking share. KLA expects China in the high-20s percent of calendar 2026 revenue and a lower share in the December quarter (earnings call, 28 October 2026). Applied's China share fell to 25% from 29% a year earlier, though its China sales rose to $2.64 billion (MLQ.ai, 12 November 2026).
• Applied's guide is less generous than its midpoint. The low ends of Applied's revenue and earnings ranges sit below consensus (investingLive, 12 November 2026), and FourWeekMBA notes the quarter has 14 weeks, one more than usual.
• The chief executive sold shares. Chief executive Rick Wallace sold 72,014 shares at $149.02 on 10 November 2026 under a Rule 10b5-1 pre-arranged trading plan (SEC Form 4 filed 12 November 2026).
• Memory spending arrives late. Micron's chief executive said on 1 October 2026 that most of its capital-spending increase is clean-room construction aimed at late 2028 and beyond; inspection tool orders from that spending would follow.

Price setup

KLA closed at $157.30 on 12 November 2026. The closes before it were $161.01 on 11 November 2026, $152.99 on 10 November 2026, $151.38 on 9 November 2026, $138.49 on 6 November 2026 and $129.80 on 5 November 2026, the day of the sector rout. The rebound since 5 November 2026 has come before Applied's results reached the market, so the 13 November 2026 session is the first to price them.

The 50-day moving average is $173.41 and the 200-day is $181.62, both as of 12 November 2026 (adjusted daily closes). A close back above the 50-day average would show the shares regaining their trend. The 52-week intraday high is $307.37 from 30 June 2026, and the last close is 48.8% below it. The 52-week closing low is $109.71 from 21 November 2025. The three-month change, measured from the 14 August 2026 close of $203.72, is negative 22.7%.

Catalysts ahead

• ~19 November 2026 (est.): Nvidia report for the third quarter of fiscal 2027. AI-spending doubts drove the 5 November 2026 chip rout; Nvidia's outlook shows whether the demand behind leading-edge tool orders is holding.
• 9 December 2026: Federal Reserve rate decision at its scheduled December meeting. Rate expectations moved the whole semiconductor group in October and November; a surprise would hit equipment shares regardless of company results.
• ~16 December 2026 (est.): Micron report for the first quarter of fiscal 2027. Shows whether memory capital spending turns into tool orders in 2027 or stays weighted to late 2028 construction.
• ~28 January 2027 (est.): KLA report for the second quarter of fiscal 2027. Settles whether revenue reaches the $4.7 billion guide, whether second-half growth of about 25% held, and what KLA sees for 2027.

What would change the view

A daily close below $140, which would give back most of the rebound from the 5 November 2026 close of $129.80 and show the selloff resuming. December-quarter revenue at or below $4.5 billion, the low end of KLA's guided range, would also break the case.

The risks this note tracks, each with what would confirm it:

• Chip-sector sentiment keeps falling, pulling equipment shares down even where company results are strong. Confirmed by: another sector-wide one-day drop like 5 November 2026 while KLA's guidance stands unchanged.
• China exposure reduces equipment revenue faster than KLA guided. Confirmed by: KLA or a peer reporting China revenue below the high-20s percent share of calendar 2026, or new US export-control changes.
• Memory capital spending lifts building costs before it lifts inspection tool orders. Confirmed by: Micron describing tool shipments weighted to late 2028 and beyond at its December report.
• The December-quarter guide misses, undermining the inspection-demand recovery. Confirmed by: reported December-quarter revenue at or below $4.5 billion, the low end of KLA's range.
• Equipment revenue peaks with calendar 2026 and 2027 starts lower. Confirmed by: KLA or Lam Research guiding March-quarter 2027 revenue below the December quarter at their late-January reports.

What it trades with

KLA trades with the chip-equipment group: Applied Materials, Lam Research and ASML. Group moves in October and on 5 November 2026 overrode company results, so Applied's 12 November 2026 report moves KLA as much as any KLA-specific news. Memory makers such as Micron shape the outlook through capital spending. Nvidia's results, hyperscaler AI-spending commentary and Federal Reserve rate expectations move the whole semiconductor group.
