Bottom line
The sleeper story is that AI infrastructure orders are finally real in Optical, not just talk, with management confirming actual bookings for GPU interconnects though refusing to quantify. Yes, the headline is ugly with Q1 guided down another 6% sequentially, but the binding constraint isn't demand, it's customer inventory digestion that management claims is measurably depleting. Most revealing quote: 'We're not counting on improvements in our orders over the next six months', essentially admitting H1 2024 is dead. My view changes if Q1 optical orders don't show sequential improvement, which would suggest structural rather than inventory issues.

The 30-second version

  • The AI infrastructure buildout is finally showing up in Optical order books, not just talk
  • Display pricing power play worked: double-digit increases stuck despite 11% volume drop
  • The $3B revenue 'spring back' math assumes zero China recovery, making it conservative
