Marvell in advanced talks to acquire Lumentum; Lumentum jumps 17% after hours

The divergent after-hours moves tell the story: Lumentum holders are being paid a premium for a strategic optical asset, while Marvell holders are pricing integration risk and dilution on a target nearly 40% of its own market value. The Nvidia stake in Lumentum adds a layer beyond a simple vendor consolidation — it makes any ownership change a question of positioning across the AI data-center supply chain, not just Marvell's balance sheet. Whether the talks convert into a signed deal, and how that Nvidia relationship is treated in any structure, is the open question worth watching.
