Lam Research Corporation (NASDAQ:LRCX) is growing faster than KLA Corporation (NASDAQ:KLAC). Yet at October 5 prices, the two semiconductor-equipment stocks carried similar consensus forward earnings multiples, while Lam cost more relative to trailing free cash flow. Investors choosing between them need to decide whether Lam’s stronger current growth compensates for that cash-flow premium.
On September 4, KLA rose about 7.3% and Lam 5.1%, while NVIDIA gained less than 1%. Find the spending shift that made the equipment rally matter beyond one trading session.

Lam offers stronger growth and substantial installed-base revenue
Lam’s July 29 results reported revenue of $6.72 billion for the quarter ended June 28, up about 30% from a year earlier. GAAP gross margin reached 51.7% and operating margin was 37.4%. Adjusted earnings per share were $1.82, close to GAAP earnings of $1.81.
Its deposition and etch equipment benefits when manufacturers add more complex process steps to advanced chips and memory. That gives Lam a way to capture spending intensity as well as new capacity. Customer support-related revenue and other revenue of roughly $2.47 billion represented about 37% of quarterly sales, providing a substantial installed-base business alongside systems. Lam’s April outlook pointed to more than 50% advanced-packaging revenue growth in 2026. Discover the manufacturing-spending mechanism that could amplify its AI exposure.
Installed-base revenue can support the business through uneven equipment demand, but it is not a guarantee of stable growth. Customer utilization, upgrades and maintenance budgets still matter. Nor should investors treat all support revenue as a fixed subscription stream.
Geographic exposure adds a distinct risk. China accounted for 26% of quarterly revenue, with Taiwan at 27% and Korea at 20%. Export restrictions and customers’ capital-spending decisions can change the revenue mix even if underlying AI demand remains strong. The growth case needs sustained spending by customers able to buy and use Lam’s equipment. Lam’s legal chief sold roughly $1.5 million of shares on August 31. Find the transaction detail that changes how bearish that sale looks.
Lam’s hedge-fund holder count in Insider Monkey’s database rose to 139 in Q2 2026 from 123 in Q1. Arrowstreet Capital reduced its shares about 6.9%, a reminder that broader participation can coexist with an individual manager’s trim.
KLA’s slower revenue growth comes with a stronger historical cash price
KLA’s July 28 results showed June-quarter revenue of $3.66 billion, up about 15%. Its inspection and metrology systems help customers identify defects and control manufacturing processes. As chips and packages become more complex, preventing a defect can protect the value of expensive wafers and downstream processing.
That is a credible investment case even when revenue grows more slowly than Lam’s. Process control can become more valuable per manufacturing step, rather than requiring investors to depend entirely on the number of new tools installed. A costlier chip makes manufacturing mistakes more consequential. See why increasing chip complexity can expand KLA’s opportunity without matching growth in wafer volumes.
For fiscal 2026, KLA reported about $4.14 billion of operating cash flow and $3.77 billion of free cash flow on $13.58 billion of revenue. Its ten-for-one June stock split is already reflected in reported per-share results; comparing an old share price with current earnings would produce a misleading valuation.
KLA remains exposed to the semiconductor capital cycle. Customers can delay orders, and export controls can restrict the addressable market. A valuable inspection franchise does not make its earnings independent of fab investment or protect an expensive stock from a valuation decline.
KLA had 81 hedge-fund holders in Q2 2026, up from 71 in Q1. Arrowstreet reduced its split-adjusted shares about 40.4%. The filings do not establish a public explanation for that reduction.
Lam and KLA qualify for our high-ROE screen, but repurchases can lift the ratio without improving a new buyer’s return. Find the other profitability leaders and the denominator warning behind the numbers.
Nearly equal earnings multiples hide a meaningful cash difference
Using the October 5 close, consensus forward P/E ratios were about 36.5 for Lam and 37.9 for KLA. Lam’s faster growth therefore came with a slightly lower expected-earnings price. Trailing price-to-free-cash-flow ratios were about 88 and 72 times, respectively, making KLA less expensive on historical cash generation.
These are demanding prices for both businesses. Trailing cash can lag growth because of working-capital investment, while forward earnings can overstate value if customer spending weakens. Lam’s bull case requires the recent expansion to produce enough future cash to close that gap. KLA’s requires process-control demand and cash conversion to remain resilient without relying on a permanently elevated multiple. A packaging supplier in our May equipment list reported 31% revenue growth, offering a different claim on the chip budget. Find that supplier and the other equipment alternatives beyond Lam and KLA.
Lam’s September 15 short-interest snapshot recorded 26,081,081 shares, 2.09% of public float and about 3.1 days to cover. It does not support a purchase thesis dependent on an unusually crowded bearish trade.
I prefer KLA for investors who prioritize cash conversion at these relative prices. Lam becomes more attractive if its stronger revenue growth persists and cash generation catches up without a deterioration in margins. That is the operating evidence needed to make its historical cash premium worth paying.
