Bottom line
The sleeper story is advanced packaging growing 70% YoY, a massive TAM expansion everyone's missing while obsessing over AI chips. The AI infrastructure boom is real but KLA is physically constrained by 18-24 month optical component lead times, making the 'unprecedented demand' narrative somewhat meaningless. The binding constraint isn't demand, it's their supply chain and their puzzling unwillingness to raise prices: as management admitted, 'we don't price based on scarcity.' My view changes if they start exercising pricing power or if memory costs normalize faster than their 2027 timeline.

The 30-second version

  • Advanced packaging is the sleeper: revenue just jumped to $1.1B guidance from $1B, growing 70% YoY, almost 2x the market
  • The obvious AI infrastructure boom is real, but KLA can't ship fast enough due to optical component supply
  • Memory pricing headwind persisting 'through at least 2027' but they won't raise prices to offset
