Bottom line
The sleeper story is six-inch indium phosphide yields beating mature production lines - this gives COHR a sustainable cost advantage that's already winning customer decisions. Everyone will focus on the 14% data center growth acceleration, but the real constraint is that supply-demand won't balance until after 2027, making this a multi-year capacity story rather than a demand story. Anderson's most revealing quote: 'I don't foresee the supply-demand getting back in balance this calendar year. I don't think it happens next calendar year.' That's a longer timeline than the market expects and means pricing power persists. The binding constraint isn't demand (book-to-bill over 4x proves that), it's execution on capacity ramp while managing cash flow from surging CapEx. My view changes if OCS revenue milestones keep getting pushed or if book-to-bill starts declining below 2x.

The 30-second version

  • Six-inch indium phosphide yields beating mature three-inch lines is the real story
  • Book-to-bill over 4x sounds impressive but reveals supply constraints are worsening
  • OCS customer count jumped from 7 to 10 but they won't quantify the $2B+ market opportunity
