Lam Research’s fiscal Q1 2027 revenue (quarter ending September 30, 2026) carries a company guide of $8.1 billion ±$400 million, implying roughly 20% sequential growth from the $6.72 billion reported in Q4 FY2026. Analysts’ consensus estimates cluster near $8.13–8.63 billion against easy year-over-year comparisons, as the prior-year quarter was $5.32 billion. Momentum stems from elevated wafer fab equipment spending now projected at low-$150 billion for calendar 2026, fueled by AI-driven NAND upgrades, DRAM/HBM capacity, and advanced packaging demand. Gross margins are guided at a record 52% ±1%, supported by favorable mix and scale. The quarter’s results will be released after market close on October 21, 2026, with any variance from the guided range likely to hinge on customer mix, China exposure, and supply-chain execution.
