Bottom line
The sleeper story is 6-inch indium phosphide yielding better than mature 3-inch lines - this is the manufacturing breakthrough that creates sustainable competitive moats through cost structure advantages. While everyone focuses on AI datacenter growth, the real edge is Coherent's unique ability to scale advanced semiconductor manufacturing at economics competitors can't match. The binding constraint shifted from capacity to execution - they have record bookings extending into 2028 but Q1 datacenter growth of only 4% shows demand far exceeds current supply capability. Anderson's telling quote: 'Our initial 6-inch indium phosphide production yields are actually higher than our current 3-inch indium phosphide yields' - this never happens in semiconductor manufacturing. My view changes if they can't quantify OCS revenue scale or if free cash flow deterioration forces slower capacity expansion.

The 30-second version

  • SLEEPER STORY: 6-inch indium phosphide yields BEATING mature 3-inch lines
  • Record bookings extending over a year out, but Q1 datacenter growth of only 4% reveals supply chokepoint
  • OCS shipped to 7 customers with 'broader applications than expected' but no revenue scale disclosed
