KLA (KLAC)

The sleeper story is advanced packaging becoming a $1B+ revenue stream outside traditional WFE, growing from 1% to 6% process control intensity in just three years with customers running 100% sampling rates due to package economics. While everyone focuses on the solid beat and guide, the real value creation is KLAC building an annuity business disconnected from memory and logic cycles. The binding constraint isn't demand but KLAC's ability to scale manufacturing capacity for specialized advanced packaging tools, which explains the conservative guidance raises. Wallace's most revealing quote: 'We think we're closer to the beginning of this trend than at the end of it' - rare long-term visibility in this industry. My view changes if advanced packaging revenue growth decelerates below 50% year-over-year or if lead times start extending again, signaling demand/supply imbalance.
