Bottom line
The SLEEPER STORY everyone's missing: Marvell's interconnect business has quietly become the pure-play AI bandwidth winner, growing 50%+ and outpacing even accelerator growth, not just cloud CapEx. The obvious headline is the guide-and-raise to $15B FY28, but the BINDING CONSTRAINT is actually execution risk on the massive inventory build and integration of acquisitions while maintaining growth momentum. Murphy's most revealing quote: 'I'm going to ignore the noise' when defending the custom business - that's either confidence or denial, but the regression from 'at least double' to 'more than 20%' growth suggests internal visibility issues. My view changes if Q1 shows inventory conversion struggles or if the interconnect business growth rate moderates toward CapEx rather than staying tied to AI acceleration.

The 30-second version

  • SLEEPER STORY: The interconnect business became THE AI BANDWIDTH PLAY and nobody's treating it that way
  • Guide-and-raise on steroids: $15B revenue target for FY28 is $2B higher than December
  • Custom business confidence regression hiding in plain sight
