What Just Happened To Marvell Stock

Shares of Marvell Technology (MRVL) fell 12.7% on Monday, November 2, 2026, the same day the company agreed to buy the data center optics maker Lumentum. The S&P 500 slipped 0.5% during the session, while two of Marvell's five chip peers, Intel and Advanced Micro Devices, also fell more than 7%. Marvell is paying for the acquisition with its own stock rather than cash. So what exactly did Marvell agree to pay for Lumentum?

What Marvell Agreed To Pay For Lumentum

The company said on November 2 that Lumentum stockholders will receive 4.500 Marvell shares for each Lumentum share they own. Because that ratio is fixed, the actual value handed over will fluctuate alongside Marvell's share price. The transaction gives Lumentum an implied enterprise value of $115 billion. Once it closes, Marvell shareholders will own about 67% of the combined company.

News reports linked Monday's fall to the acquisition and the purchase price, which values Lumentum at five times its price a year earlier. The companies said the combination would create a category leader in AI connectivity. Connectivity is already central to Marvell. On its August 27 call, management said interconnect continues to lead the way in its growth, and that its fiscal 2028 revenue outlook for scale-up optics had increased meaningfully.

Did Marvell Fall Alone Or With Chip Stocks?

Marvell fell much further than its sector during the session. The technology sector fund XLK dropped 2.9%, and Marvell's decline was more than four times as large. Three of its five peers, Broadcom, NVIDIA and Qualcomm, each fell less than 2%. Intel and Advanced Micro Devices faced a harder day, dropping 8.8% and 7.5%. Marvell's drop was mostly its own, though two of its peers fell more than half as far.

Where Marvell Stock Stands After Three Down Days

Monday marked Marvell's third consecutive fall. The stock lost 13.2% on October 29, which news reports linked to a report that Marvell was close to buying Lumentum, and it lost another 10.0% on October 30. Declines as large as Monday's are rare for Marvell, with only two sessions in the prior 365 days dropping at least as much.

Marvell lost 37.0% over the month to November 2, compared to a 2.3% fall for the S&P 500. Over twelve months it is still up 93.9%, against 11.8% for the index. The latest close sits well below the 52-week high close of $316.43 set on June 4, 2026. Marvell finished November 2 at $171.41, about 46% below that high.

Even after the drop, Marvell trades at 16.3 times its sales over the past twelve months, against 3.3 times for the S&P 500.

Marvell is expected to report its fiscal third-quarter results later in November 2026. The figure to watch is data center revenue, which management guided on its August 27 call to grow roughly 75% from a year earlier.
