Lam Research (LRCX) FY2026 results: revenue $23.2 billion, up 26.0% on the year

Lam Research was incorporated in Delaware in 1980, is headquartered in Fremont, California and keeps a network of facilities across Asia, Europe and the United States. It supplies wafer fabrication equipment and services to the semiconductor industry, with competencies it lists as nanoscale manufacturing enablement, chemistry, plasma and fluidics, systems engineering and operational disciplines. The filing describes its customers as memory makers, foundries and integrated device manufacturers producing non-volatile memory, dynamic random-access memory and logic devices, whose chips go into mobile phones, personal computers, cloud and enterprise servers, wearables, vehicles and data storage. Making those chips means repeating a set of core processes over hundreds of individual steps, integrating new materials with control at the atomic scale, on equipment that also has to be productive and cost-effective.

What is driving demand

The company points to demand for electronic systems supporting artificial intelligence, cloud infrastructure, communications, automotive and industrial uses, which needs high performance, energy efficient and highly integrated devices. Because traditional two-dimensional scaling is getting harder, manufacturers are turning to vertical scaling, three-dimensional architecture, more sophisticated patterning, new materials and advanced integration, all of which raise manufacturing complexity and precision requirements. The company argues that several things differentiate it: research and development across sustaining engineering, product and process development and feasibility work; cycles of learning drawn from a broad installed base; collaboration with ecosystem partners and closeness to customers; investment across the breadth of its portfolio; and delivery of multi-product solutions.

Deposition, etch and clean

Deposition creates the insulating and conducting layers of a device: electrochemical deposition makes the copper wiring that links devices on a chip, chemical vapour and atomic layer deposition build tiny molybdenum or tungsten connectors and thin barriers a few atomic layers at a time, and plasma-enhanced and atomic layer processes form the critical insulating films, with treatments such as ultraviolet thermal processing improving them. Etch creates chip features by selectively removing dielectric, metal, silicon and poly silicon material, with reactive ion etch enabling transistor performance, storage capacitors and memory cells, and low temperature cryogenic etching allowing new chemistries for high aspect ratio work. Clean steps clear particles, contaminants and residues between manufacturing steps and prepare the wafer surface, with wet processing for cleaning and etch and plasma bevel cleaning removing material from the wafer edge. Product families include ALTUS, SABRE, Striker and VECTOR in deposition, Akara, Flex, Kiyo, Syndion, Vantex and Versys Metal in etch, and Coronus, DV-Prime, Da Vinci, EOS and the SP Series in clean.

Dry resist and packaging

Dry extreme ultraviolet resist is a patterning approach the company says raises device scaling and pattern density while cutting cost and complexity; instead of wet-spin processing the film is formed by gas-phase deposition, which it describes as giving superior molecular purity and image fidelity with less environmental impact, sold as the Aether family. It also addresses back-end wafer-level packaging, an alternative to wire bonding that can give a smaller form factor, faster interconnect and lower power use, including fan-out panel-level packaging, where chips are cut from a substrate sheet several times the size of a silicon wafer to raise yield, and three-dimensional stacking of high bandwidth memory. Its products also suit related markets that rely on semiconductor processes, such as complementary metal-oxide-semiconductor image sensors and micro-electromechanical systems.

Services, selling and people

The Customer Support Business Group sells products and services meant to keep installed equipment performing, covering customer service, spares, upgrades and refurbished older-generation products across deposition, etch and clean. Many technical advances in the newest products are also sold as upgrades, which the company presents as a cost-effective way to extend existing fabrication lines, while its Equipment Intelligence services work on uptime, throughput and defect reduction and the spares line on running costs and product life. The Reliant line within that group sells new and refurbished older-generation products for applications that do not need the most advanced processing. Marketing and sales run through product marketing and sales staff alongside equipment and process engineers working with individual customers, backed by service engineers across the United States, China, Europe, India, Japan, Korea, Southeast Asia and Taiwan, and systems carry a standard warranty against defects in material and workmanship. Much of its sales and operations sit outside the United States, exposing the company to export restrictions, tariffs, staffing and management difficulties, tax consequences, currency movements and political conditions. At 4 August 2026 it had approximately 23,300 regular full-time employees, over 26% of them in research and development, approximately 38% in the United States, 56% in Asia and 6% in Europe.
