Lam Research builds the machines that chip factories use to lay down and carve the tiny layers on a silicon wafer. Its September quarter revenue hit a record $8.22bn. That is up 22% from the June quarter. By our arithmetic, $8.22bn is up 54% from $5.32bn a year ago, both figures from the release. It also came in above the $8.14bn consensus as reported by MarketBeat. Profit per share was $2.19, the company says, up from $1.24 a year earlier. Sales of new equipment grew fastest, at $5.73bn. China made up 35% of revenue. CEO Tim Archer said "AI driving higher semiconductor demand and greater device complexity" helped Lam post record revenue, profit and earnings per share. For the December quarter Lam expects revenue of about $8.60bn. Why it matters to you: before any AI chip ships, a factory needs tools like Lam's to make it, so this is an early read on how fast the AI build is moving. Filing: Lam Research 8-K, filed 21 Oct 2026

Year on year changes are our arithmetic from the same release's figures for the September 2025 quarter, and the company itself states only changes from the June quarter. The release gives no AI revenue figure, so the AI link rests on the CEO's words. Only revenue is set against consensus. No share prices or price moves.
