Lam Research Corporation (LRCX.BA) Stock Analysis & Winston Score

Lam Research makes machines that help build computer chips. Its equipment is used in a process called "etching and deposition," which carves tiny patterns onto silicon wafers and adds thin layers of material to them. The company sells these machines to major chipmakers like Samsung, TSMC, and Micron, making it one of the most important suppliers in the global semiconductor manufacturing industry. Lam earns money by selling its equipment to chip factories and then charging for ongoing services, spare parts, and upgrades — a model that creates steady repeat revenue. It operates globally, with a large portion of sales coming from Asia, and generates roughly $15 billion in annual revenue. Its deep technical expertise and the high cost of switching to a competitor give it a strong competitive position, but the business is heavily tied to how much chipmakers are spending on new factories, meaning a slowdown in chip industry investment is its biggest near-term risk.
