Advanced packaging growth
KLA started FY2026 highlighting advanced packaging as a meaningful served market with momentum. In Q2 it guided continued mid-to-high teens growth, and in Q3 revised advanced packaging process control revenue to about $1B in 2026. By Q4 it guided ~$1.1B and cited fast-growing process control needs.
Memory intensity & pricing headwinds
Management tied DRAM intensity acceleration to EUV and especially HBM requirements (less redundancy, higher reliability constraints, and more rigorous inspection). At the same time, it described a transitory gross margin headwind from elevated DRAM costs used in image processing computers, with continued negative impact through 2026.
Capacity & supply constraints
Throughout the year, management described how long lead-time components and lead-time normalization affected first-half versus second-half shipment cadence. In Q2 and Q3 they discussed product supply constraints and optical component capacity, and by Q4 they cited supply coming online enabling roughly 20% second-half 2026 growth over first half.
