Lam Research closed its fiscal fourth quarter with record revenue of $6.72 billion, a 30% jump from a year earlier, driven by heavy demand for AI-related chips. The company is guiding first-quarter revenue to $8.1 billion, a sign that the equipment maker expects the surge to keep rolling into 2027.
AI demand fuels the equipment boom
The numbers reflect how far the semiconductor toolmaker has ridden the AI wave. Chipmakers are building out capacity for the processors and memory used in data centers, and that means buying more of the etching and deposition machines Lam makes. The company's quarterly result topped its own prior outlook, and the year-over-year gain of 30% shows no slowdown in spending from customers.
Lam's guidance for the current period is even stronger. The $8.1 billion forecast for the first fiscal quarter of 2027 would mark another sequential increase of more than 20% from the record quarter just reported. Management said growth is expected to extend through the year, fueled by the same AI build-out.
What the guidance says about 2027
The jump in guidance suggests the company sees no letup in orders. Chipmakers are still working through multi-year plans to add capacity, and Lam's tools are essential for making the most advanced nodes. The company's own statements point to AI as the central driver, not just a bump.
The guidance implies that Lam Research expects the strong run to continue well beyond the next quarter. The company's fiscal year 2027 starts with that $8.1 billion forecast, and the revenue pipeline looks healthy. Whether that pace holds through the rest of the year will depend on how much longer the AI build-out keeps its momentum.
Lam's next earnings report will show whether it can beat that $8.1 billion target and how management sees the rest of the year shaping up. For now, the numbers point to a company that's still in the middle of a very strong cycle.
