Lam Research's board approved a share buyback of up to $25 billion with no end date. It also reaffirmed a quarterly dividend of $0.33 per share. The shares trade at $222.39, down 28.16% over 30 days and 34.01% over 90 days. Over one year, total shareholder return is 38.41%. The chipmaking equipment maker posted four straight quarters of record revenue. The June 2026 quarter brought $6.72 billion, up 30% year over year, with a gross margin of 52%, the highest in twenty years. A community narrative puts fair value at $423.85, while a discounted cash flow model suggests about $178. Risks include memory makers cutting capital spending and tighter China export rules.

Lam Research shares fell 13.46% to $191.63 at 10:55 ET on November 5, as investors reassessed AI-linked spending on chip equipment. The drop follows strong results. On October 21, the chip-manufacturing equipment supplier reported September-quarter revenue of $8.219 billion, up about 22% from $6.722 billion in June. GAAP operating margin rose to 40% from 37.4%, and diluted earnings per share climbed to $2.19 from $1.81. Management credited AI-driven chip demand, more complex chip designs, and operational execution. Future performance depends partly on customer spending and the timing of equipment acceptance. The shares trade at a price-to-earnings ratio of 28.51.

Lam Research reported first quarter 2027 revenue of $8.22 billion and net income of $2.75 billion. The chip equipment maker guided to December quarter revenue of about $8.6 billion and earnings per diluted share near $2.33. Management warned of component shortages and an expected near-term drop in China-related revenue. Export controls and China exposure remain the biggest risks. The company expects wafer fabrication equipment spending to exceed $200 billion in 2027, driven by gate-all-around transistors, EUV lithography, backside power delivery, and advanced packaging. Analysts forecast revenue of $49.9 billion and earnings of $18.5 billion by 2029. Shareholders also backed all proposals at the annual meeting, including electing 10 directors.
