Customer Support Business Group
Customer support revenue grew 42.8% in the June 2026 quarter, the fastest of Lam's two revenue lines.
The numbers
What it is
Spare parts, upgrades, refurbishment and service for the installed base of Lam tools. The company reports this line as 'customer support-related revenue and other'. It grows with the number of Lam tools in fabs and with upgrades to existing tools.
Why it matters to the stock. Support revenue is recurring and tends to hold up when new systems orders slow. A trader uses it to judge how much of Lam's revenue is steady and how much depends on new fab build-outs.
