Lam Research (US5324571083) stock was up 4.72% to $326.11 in the prior close snapshot and traded at $326.50 in a later premarket update on August 13, 2026, with a market value of $408.07 billion. The move came alongside a sharp semiconductor bid, and the latest reported quarter showed $6.72 billion in revenue and $1.82 in non-GAAP EPS.
Quarterly numbers stay strong
The strongest recent operating figures came from the quarter ended June 30, 2026, when revenue reached $6.72 billion, up 30.0% year over year, and gross margin expanded to 51.7%. Non-GAAP EPS of $1.82 beat the $1.68 estimate by 8.10%, a gap that keeps the latest report in focus for investors.
That combination matters because the stock's current value already reflects a large rerating: MarketBeat's stock page showed a $326.11 close, while the same day's quote snapshot also listed a $408.07 billion market capitalization and a 52-week range of $94.11 to $438.50. A higher starting point leaves less room for simple multiple expansion and puts the next quarter's guidance front and center.
Guidance sets the tone
The most recent outlook points to another heavy quarter, with September quarter revenue guided at $8.10 billion plus or minus $400 million and EPS at $2.15 plus or minus $0.15. On that setup, Lam Research is no longer trading as a pure recovery story; the market is now weighing whether the next print can convert strong wafer-fab equipment demand into another beat.
Semiconductor peers helped the tone as well, with a regional chip rally cited on August 13, 2026 after softer U.S. inflation data and better AI infrastructure earnings. Lam Research's 4.72% rise fits that broader tape, but the company's own $6.72 billion quarterly revenue and 51.7% gross margin still do most of the analytical heavy lifting.
Products still matter
Lam Research's business centers on wafer fabrication equipment used in etch and deposition steps, where its installed base and service revenue can cushion swings in tool demand. That model explains why a quarter with $6.72 billion in sales and a $2.15 EPS guide can move the stock even when the broader semiconductor backdrop is already strong.
Shares and valuation
Lam Research stock was quoted at $326.50 in a delayed premarket update on August 13, 2026, after closing at $326.11 in the prior session. The same quote snapshot put the company at a $408.07 billion market capitalization, which leaves the market focused on execution rather than just momentum.
