Bottom line
The sleeper story is IST's 50%+ growth and diversification across compute SLT, mobile, and HDD - providing a hedge against VIP concentration that nobody's talking about. While everyone focuses on AI driving 70% of Q1 revenue, management explicitly warned of a '2-3 quarter surge followed by digestion' - the first time they've been this specific about an AI pullback. The binding constraint is timeline uncertainty: they're more confident than ever about reaching $6B revenue but switched to an 'evergreen' model because AI lumpiness makes dating impossible. Greg's most revealing quote: 'One big socket sliding across year boundaries could have significant positive or negative effect on year-to-year growth.' My view changes if they can provide specific merchant GPU timelines or quantify what the 'digestion period' looks like - without that visibility, we're riding a very fast but unpredictable wave.

The 30-second version

  • IST becomes the sleeper diversification story - tripling HDD revenue, winning compute SLT across multiple customers
  • AI revenue acceleration to 70% of total by Q1 2026, but management warns of '2-3 quarter surge' followed by 'digestion'
  • New target model abandons date certainty - revenue nearly doubles to $6B but it's now 'evergreen' not year-specific
