What these concentrations mean together
updated 2026-06-24The company's concentration profile is dominated by two high-share exposures — one geographic, one customer — that are closely linked. International revenues represented 75.9% of total revenues for fiscal year 2025, a high-share structural exposure reflecting that the semiconductor equipment subsystem industry is anchored in Asia-Pacific manufacturing hubs. This is structural in character: the geographic mix mirrors where semiconductor fabs and OEM assembly is concentrated globally rather than representing a reliance on a particular country or customer relationship. The customer concentration is the more idiosyncratic of the two disclosures. Applied Materials, Inc. and Lam Research Corporation together accounted for 58.7% of revenues for fiscal year 2025, a high-share dependency exposure. Concentration in the top two customers at that share means that capital spending cycles, program wins and losses, and inventory management decisions at those two accounts would flow directly into results. The geographic and customer concentrations partially overlap, since both Applied Materials and Lam Research have significant equipment production and service activity in the same Asia-Pacific regions that drive the international revenue share. Together the two exposures make the company's revenue trajectory closely tied to semiconductor equipment capex cycles and the specific wallet-share dynamics with its two largest OEM partners — the primary variables to monitor for this business.
