Is Marvell Technology (MRVL) Cheap After Its Lumentum Deal Talks Sent Shares Lower?

Marvell Technology (MRVL) is back in focus after reports it is in advanced talks to acquire data center optics specialist Lumentum in a potential all stock transaction closely tied to AI infrastructure demand.

That backdrop helps explain the sharp move in Marvell Technology’s share price, which fell about 13.2% in the latest session and is down roughly 17.4% over the past month, even though the 90 day share price return is positive and the year to date share price return of 144.3% sits alongside a 1 year total shareholder return of 133.3% and a 3 year total shareholder return above 3x. This pattern suggests strong longer term momentum colliding with fresh concerns about deal dilution, funding and AI spending risk.

Most Popular Narrative: 36% Undervalued

Marvell Technology’s most followed narrative pegs fair value at $339.36, well above the latest $218.34 close. This means the recent pullback still sits against a framework that assumes a much higher long term earnings and AI infrastructure opportunity.

The expected expansion of the custom business, which is guided to more than double year over year in FY28 and to accelerate in FY29 across XPU and XPU attach programs with large hyperscalers, gives Marvell a path to higher long term revenue and potentially more diversified earnings streams.

See why 344 investors see Marvell Technology as 36% undervalued.

Result: Fair Value of $339.36 (UNDERVALUED)

Still, the narrative could crack if AI related spending slows, or if Marvell Technology’s lower margin custom programs weigh more heavily on profitability than expected.
