Lam Research shares surged 5.06% in pre-market trading, extending a powerful rally from the prior regular session.

The pre-market jump came after the semiconductor equipment maker reported fiscal fourth-quarter results that comprehensively beat market expectations. Adjusted earnings per share reached $1.82, surpassing the $1.68 consensus, while revenue hit an all-time high of $6.722 billion. Gross margin improved to 51.7% from 49.8%, and operating margin expanded to 37.4% from 35.0%. More importantly, next-quarter guidance far exceeded analyst forecasts, with projected revenue of $7.7 billion to $8.5 billion versus the $7.11 billion estimate, and EPS guidance of $2.00 to $2.30, well above the $1.84 consensus.

CEO Tim Archer noted that AI-driven demand continues to reshape the semiconductor industry, sustaining elevated equipment demand and fueling the company’s record performance. The strong outlook reinforced investor confidence, driving the stock higher in the pre-market session.
