KLA Corporation (NASDAQ:KLAC) drops 8.7% premarket with cash conversion trailing despite record sales

NEW YORK, July 29, 2026, 06:59 EDT

  • KLA shares were seen at $174.25 in premarket trading, down 8.7%.
  • KLA Corporation reported a 15.2% increase in quarterly revenue, while free cash flow declined by 23.2%.
  • Revenue guidance for September exceeded expectations, while margin growth was still constrained.

KLA shares continued to drop ahead of Wednesday’s U.S. trading session, falling 8.7% in premarket activity to $174.25. The stock was set for a two-day loss of 14.3% from Monday’s closing price.

The company exceeded forecasts for sales and adjusted earnings. Revenue came in at $3.66 billion, ahead of the anticipated $3.60 billion. Adjusted earnings were $1.05 per share, topping consensus by five cents.

Guidance for September-quarter revenue topped expectations. The midpoint was set at $4.0 billion, above analysts’ average estimate of $3.92 billion. However, shares declined.

Anticipation for results was elevated, with KLA’s shares rising over 57% so far this year ahead of Tuesday’s announcement. CFRA analyst Brooks Idlet described the results as “not eye-popping by any means.” Reuters

The clearer indicator for investors was in cash generation. Sales increased by 15.2%, but free cash flow declined by 23.2%.

MetricQ4 FY2026Q4 FY2025Change
Revenue$3.658 billion$3.175 billion+15.2%
GAAP net income$1.363 billion$1.203 billion+13.3%

Free-cash-flow margin22.3%33.5%-11.2 points
Operating cash flow/net income66.5%96.9%-30.4 points

The calculations above are based on company data. All per-share figures account for the ten-for-one stock split in June.

Operating cash flow accounted for 66.5% of net income, down from 96.9% the previous year. Movements in operating assets and liabilities used roughly $749 million.

Chief Financial Officer Bren Higgins attributed the cash outflow to working-capital needs and facility investments. Such usage aligns with expanding capacity, but it still leaves inventory and collection risks in place.

Stock chart for NASDAQ:KLAC

Management provided a preliminary backlog estimate close to $12.5 billion, which represents about 92% of projected revenue for fiscal 2026. This level of visibility offers investors some reassurance, even as quarterly cash conversion shows softness.

KLA distributed $876 million via share repurchases and dividends, surpassing its quarterly free cash flow by $59 million. For the entire year, total shareholder returns did not reach the year’s free cash flow.

The midpoint for September revenue points to a 9.4% increase from the prior quarter. Guidance for gross margin edges up by only 0.1 percentage point from June’s 62.4%. Investors seemed to expect greater incremental leverage.

Indicators of demand stayed solid. KLA forecasts advanced-packaging systems revenue will reach close to $1.1 billion this year, surpassing 2025 by over 70%. Services revenue climbed 17% to $820 million.

Chief Executive Rick Wallace stated that momentum is “accelerating in the second half of calendar 2026.” He anticipates this strength will persist through 2027. KLA Corporation

The decline was part of a wider pullback in the equipment sector. Shares of Applied Materials Inc. slid 7.9% on Tuesday. Lam Research Corp. declined 7.5%. ASML Holding N.V. was down 4.4%.

Potential risks are stricter regulations in China, tariffs, fluctuations in memory prices, and extended lead times for components. Customer spending continues to be both cyclical and focused. Premarket prices may experience significant changes before trading starts at 09:30 EDT.

Further analysis

What is causing KLA shares to decline despite surpassing earnings expectations?

KLA shares ended Tuesday, July 28, at $190.80, down 6.18% ahead of its earnings report. In early Wednesday premarket trading, shares were around $175, representing an additional 8% drop from Tuesday’s close. KLA beat earnings forecasts, but only by a small amount. Revenue topped consensus by 1.7%, and adjusted EPS was 5% above expectations. There was no clear single driver behind the moves. Elevated expectations, unchanged margin guidance, and ongoing chip-equipment sector weakness all appeared to play a role. MarketWatch

Did KLA outperform Wall Street expectations in the fourth quarter?

Yes, and the company delivered strong operational results. Revenue came in at $3.66 billion, topping the $3.60 billion forecast from LSEG. Sales climbed 15% from a year ago and increased 7% from the prior quarter. Adjusted earnings per share totaled $1.05, ahead of the $1.00 consensus. GAAP net profit was $1.36 billion, while the adjusted gross margin stood at 62.4%. All per-share data reflect the ten-for-one stock split on June 11. Reuters

How robust is KLA’s forecast for the September quarter?

KLA forecast September-quarter revenue at $4.0 billion, with a possible variance of $200 million. The previous Wall Street LSEG consensus forecast stood at $3.92 billion. The company projected adjusted EPS at $1.16, plus or minus ten cents, versus the prior $1.14 consensus. At the midpoint, guidance points to approximately 9.4% sequential growth from June. Still, the broad range highlights ongoing risks around execution and product mix. KLA Corporation

Is demand related to AI continuing to grow for KLA?

Operating figures continue to support a positive outlook, at least currently. KLA lifted its 2026 advanced-packaging process-control revenue forecast to around $1.1 billion, projecting more than a 70% increase over 2025. Semiconductor Process Control revenue came in at $3.26 billion, marking a 13% rise on the year. Management also boosted its 2026 projection for the wafer-equipment market, now guiding to the low-$150-billion band. The company anticipates second-half revenue to be roughly 20% higher compared with the first half. These predictions remain subject to changes in customer demand timing and supply chain conditions. Investing.com

What portion of September-quarter demand is expected to be attributed to memory?

KLA forecasts that memory will account for 27% of sales in semiconductor process-control systems, while foundry and logic are projected to make up the remaining 73%. In the memory segment, DRAM is expected to deliver around 90% of sales, with NAND comprising close to 10%. Management anticipates memory’s share will climb again during the December quarter. The change is positive for growth, but it also raises exposure to memory-cycle fluctuations. Investing.com

Are supply constraints and margins increasingly significant risks?

Adjusted gross margin for the June quarter reached 62.4%, aligning with the upper end of the company’s forecast. September quarter guidance is 62.5%, plus or minus one percentage point, indicating little change. Management noted that increased memory-component expenses could continue weighing on margins through 2027. Average companywide lead times are about 12 months, with some products extending to 18–24 months. Tariffs and other input cost increases are also putting pressure on margins. Additional supply is expected to support second-half shipments, though the exact timing is still unclear. Investing.com

What level of risk does KLA face from exposure to China?

China accounted for 26% of revenue in the June quarter, placing it just behind Taiwan’s 31%. This represents significant exposure. U.S. export regulations may restrict KLA from selling to or servicing certain Chinese clients. Competition from domestic Chinese equipment makers remains a noted market risk. KLA maintains that its process-control technology is challenging for competitors to duplicate. That, however, reflects management’s stance rather than a conclusion the market has independently confirmed. Investing.com

Has the recent selloff resulted in KLA stock becoming undervalued?

KLAC is trading at approximately $175, which represents about 46.5 times projected fiscal 2026 adjusted earnings. On a GAAP basis, the multiple is around 47.8 times. While this valuation is below where shares closed on Tuesday, it does not represent a clear bargain. The stock has declined roughly 43% from its 52-week peak of $307.37, but remains more than twice its 52-week low of $83.22. Free cash flow for the fiscal year totaled $3.77 billion, equivalent to around 28% of revenue. KLA distributed $3.35 billion via share repurchases and dividends. Public

What key developments should investors focus on in the week ahead?

The immediate focus is whether KLAC can hold near the $175 level in premarket trading, as low volume makes this area unreliable as support. Analyst estimates are expected to adjust following KLA’s $4.0 billion revenue outlook and $1.16 guidance. After Tuesday’s selloff across the sector, keep an eye on Applied Materials and other equipment stocks for further movement. KLA’s schedule shows no upcoming confirmed investor events. With that, estimate changes, sector momentum, and broader macroeconomic updates are set to be the main influences. Public
