Bottom line
The sleeper story is that HPC with Amazon could become a $400M+ business based on peer comps, creating an entirely new growth vector nobody's modeling while everyone fixates on the datacom recovery narrative. Yes, Q4 beat expectations, but the real story is that component shortages are artificially capping growth just as 1.6T demand explodes, creating a coiled spring setup for when supplies normalize in 1-2 quarters. The binding constraint isn't demand, it's 200-gig per lane EML availability, and Seamus admitted 'demand is outstripping supply right now.' Most revealing quote: 'We're evaluating options to accelerate Building 10 completion,' which you don't do unless demand visibility is explosive. My view changes if free cash flow doesn't recover above $50M next quarter, signaling structural rather than temporal issues.

The 30-second version

  • HPC emerges as the real growth driver while everyone obsesses over datacom recovery
  • Supply constraints artificially depressing datacom just as 1.6T demand explodes
  • DCI quietly became a $400M+ annualized business growing 45% YoY
