Marvell Falls 28.1% in a Week After Lumentum Deal and Higher Outlook

Published November 7, 2026 · 6 sources

Marvell Technology had a sharp weekly decline despite a higher revenue outlook, as its all-stock Lumentum acquisition raised questions, outlets report.

What happened

Marvell Technology shares dropped 28.1% over the week, according to The Globe and Mail. Pluang reports that Marvell and Western Digital had their worst weekly decline since 2001, even though both raised guidance.

Scanx.trade reports that Marvell lifted its two-year revenue outlook to $30 billion, citing AI demand. TradingKey links the pressure on the shares to an all-stock acquisition of Lumentum, which it says pushed the stock to near a seven-month low.

TradingKey also notes that the $110 support level is facing a test. Ad-hoc-news.de reports a 6.2% bounce and discusses whether the Lumentum deal can justify itself, as well as dilution concerns tied to the all-stock structure.

Context

In an all-stock acquisition, the buyer pays with newly issued shares, which can increase the number of shares outstanding and is often debated by investors as dilution.

Why it matters

The episode shows how a stronger revenue outlook can be weighed against concerns over the cost and structure of a large acquisition.
