On June 11, Barclays analyst Tom O’Malley lifted the firm’s price target on Lam Research Corporation (NASDAQ:LRCX) from $275 to $335, while keeping an ‘Overweight’ rating on the shares.

Lam Research raised its 2026 wafer fabrication equipment (WFE) outlook to $140 billion, with bias to the upside. This is up from the company’s prior forecast of $135 billion. The revised estimate was driven by improvements in all end markets over its most recent quarter.

RBC raised its forecasts to reflect the stronger expectations for both pricing and volume. According to the firm, the current DRAM upcycle, which has already lasted 12 quarters, still has steam and could run for another 5-6 quarters.
