What happened
Marvell has signed an all-stock deal to acquire optical chip and networking equipment maker Lumentum, with an enterprise value of $115 billion (including debt) and an equity value of about $80 billion — 4.5 Marvell shares per Lumentum share. For scale, that tops Microsoft's $68.7B Activision Blizzard deal in 2022 and Dell's $67B EMC deal in 2016. Nvidia is a common shareholder: it put $2 billion into Lumentum in March for laser components and fab expansion, and $2 billion into Marvell the same month for its optical networking portfolio. The deal is expected to close in the first half of calendar year 2028, pending shareholder and regulatory approval.
Why it matters
There is nothing here to change what you ship this quarter: the close date is H1 2028, so any effect on optical component pricing, availability, or vendor choice is years out. The one decision-relevant signal is Nvidia funding both sides of the deal — if your AI infrastructure plans depend on optical interconnect supply, expect further consolidation around Nvidia-aligned suppliers, and treat single-vendor assumptions in that layer as a risk to model rather than a settled fact.
Discussion angle
Nvidia invested $2B in each company months before they merged — is this vertical consolidation of the AI optics supply chain, and what does a 2028 close date mean for anyone building capex or vendor plans on top of it now?
