KLA Corporation stock cratered 40% over 30 days; Wall Street pro forecasts 75% upside over next 12 months.

KLA Corporation (NASDAQ:KLAC) trades at $182.82, with the average Wall Street price target at $230.85, implying roughly 26% upside. Cantor Fitzgerald's $325 target represents about 78% upside from current levels.

KLA dominates semiconductor process control—the inspection and metrology tools that detect defects on wafers as chipmakers advance into 2nm logic, high-bandwidth memory stacking, and advanced packaging. Wall Street has positioned it as a pure-play AI infrastructure beneficiary, which explains the jarring nature of the recent decline.

With the stock trading well below consensus and even further below the Street high, the core question is whether the market has correctly repriced KLA's China exposure or overreacted to fundamentals that remain intact.

In its latest quarter, KLA delivered non-GAAP EPS of $1.05 versus a $0.9987 estimate—a 5.14% beat—on revenue of $3.66 billion, up 15.21% year over year and marking the fifth consecutive quarterly beat. Despite this, shares cratered 10.8% on the report and have continued sliding, down 31.32% over the last month and roughly 40% from the $307.37 52-week high.

The Q1 FY2027 revenue guide of $4.0 billion plus or minus $200 million came in below the whisper number, and management flagged evolving U.S. Bureau of Industry and Security rules on China sales as a live risk. China contributed $4.04 billion of FY2026 revenue. A 4% decline in the Philadelphia Semiconductor Index and a trailing valuation of 50x earnings amplified the selloff.

Despite the pullback, analysts have held firm. The consensus spans 5 Strong Buys, 13 Buys, 10 Holds, and 1 Sell, with post-earnings revisions skewing higher. JPMorgan raised its target to $238 from $200 and named KLA its top semiconductor-equipment pick. Jefferies increased its target to $210, citing a backlog inflection point. Zacks upgraded the stock to Strong Buy.

Cantor Fitzgerald raised its target to $325 from $250, arguing that KLA's optical and electron-beam inspection tools become indispensable as chipmakers shrink to 2nm and 3nm logic and stack additional HBM layers. Defect detection has become the primary yield bottleneck in gate-all-around and advanced packaging architectures, positioning KLA to command pricing power and capture an outsized share of capital-intensity benefits versus broader wafer-fab-equipment peers.

CEO Rick Wallace stated that momentum is "accelerating in the second half of calendar 2026 and continuing through 2027," with advanced packaging revenue projected to grow more than 70% in 2026. Analysts are anchoring their targets on a 12-month recovery that extends through the September 2026 guide and into calendar 2027.

Peers are similarly pressured. Applied Materials (NASDAQ:AMAT) trades at $507.67, down 22.01% over the past month, with a consensus target of $627.66 implying about 24% upside. Lam Research (NASDAQ:LRCX) sits at $293.02, off 25.11% in a month despite an 8.1% earnings beat, while its $368.13 consensus target implies roughly 26% upside across 29 Buy-or-better ratings out of 35 analysts. Onto Innovation (NYSE:ONTO), the smaller process-control peer, trades at $258.58 after a 26.41% monthly decline, with a $369.60 consensus target implying the widest consensus gap in the group at about 43% upside and a clean 10 Buy ratings with zero Holds or Sells.

KLA's trailing P/E stands at 50, with forward P/E at 34. Year to date, KLA is up 50.85% versus 9.55% for the S&P 500, making the recent decline a correction within a strong year rather than a reversal.

The bull case rests on the AI capex cycle extending into 2027, defect-control intensity rising with 2nm and HBM advancement, and the China revenue impact being absorbed rather than compounded. Management's $4.0 billion Q1 FY2027 guidance would represent meaningful sequential acceleration. Free cash flow of $817 million plus $571 million in quarterly buybacks funds investor patience through the cycle.

The bear case strengthens if BIS rules tighten further on China sales, if hyperscaler AI spending cools, or if the market reprices a 50x trailing multiple as too steep for a cyclical equipment maker. Cash flow fell 22.19% year over year in the quarter, and insider activity has tilted toward selling.

The selloff appears to reflect sentiment resetting rather than fundamentals deteriorating. The consensus 26% upside gap looks defensible even if Cantor's 78% call proves aspirational.
