# Why Marvell (MRVL) fell 10.99% on October 29, 2026

Marvell (MRVL) fell 10.99% on October 29, 2026 — Possible Lumentum buy sparks big-deal dilution fears.

## What happened

Marvell fell about 11% on a report that it could acquire Lumentum, which popped on the news. The deal would be a large strategic purchase for Marvell, and the reaction hit Marvell rather than the target.

## Why it moved

A large acquisition typically raises dilution and near-term margin pressure, and investors price that in quickly when the buyer is the one paying up.

## Why it matters

Marvell sits in the AI Compute theme, where hyperscaler and neocloud GPU buildouts have driven demand for months.

## What would break the thesis

If the rumored price is modest or Marvell walks away from the deal, the dilution overhang disappears and the stock can recover.
