Bottom line
The market sees 35% Data Center growth and celebrates, but the real story is an unquantified mix shift to optical components that management refuses to size despite it driving their entire bull case. They raised FY26 Data Center growth to >60% yet won't tell you what percentage is optical versus traditional analog, dodging every attempt to pin down photodetector revenue. The binding constraint isn't demand, it's optical component capacity and reliability, evidenced by the emergency IQE investment and CW laser timeline slipping to FY27-28. Most revealing quote: 'We don't typically break out revenue by product line, mainly for competitive reasons' while simultaneously claiming optical is driving everything. My view changes if they actually quantify optical revenue mix and show CW lasers shipping in volume before FY28.

The 30-second version

  • The sleeper: Data Center optical components are quietly becoming the growth engine while everyone debates AI infrastructure
  • The obvious 35% sequential Data Center growth masks a critical shift: this is optical-driven, not traditional analog
  • The red flag: DSO improved mysteriously from 54 to 50 days while receivables stayed flat at $160M
