Bottom line
The sleeper story is Thailand's pull-forward revealing hyperscaler panic about 800V transition, where AE claims 98% efficiency leadership. Yes, they beat and raised, but operating cash flow went negative despite record margins, suggesting they're either stuffing the channel or customers are stretching payments. The binding constraint isn't their technology or capacity anymore, it's working capital management and their customers' own downstream bottlenecks. Most revealing quote: 'frequent customer changes in demand mix due to various downstream constraints.' My view changes if Q2 operating cash flow doesn't turn strongly positive, proving Q1 was just timing.

The 30-second version

  • Thailand capacity pull-forward reveals hyperscaler desperation for 800V transition
  • Semi guidance went from 'flattish' to '2H up 30%+' in 90 days
  • Cash flow turned negative despite 'record' everything
