Marvell downgraded on $100B Lumentum acquisition concerns
Bank of America downgraded Marvell Technology to neutral from buy, citing concerns over its announced all-stock acquisition of photonics firm Lumentum Holdings. The deal, valued at over $100 billion, aims to position Marvell as a leader in AI connectivity but faces extended regulatory review, limited EPS accretion, and potential customer conflicts. Analyst Vivek Arya lowered the price target to $225 from $400, implying 31% upside. Shares closed down 13% on Monday, adding to a 12% decline over three months. The downgrade contrasts with consensus, as most of the 45 analysts covering the stock maintain buy ratings.
Marvell's acquisition of Lumentum is a major semiconductor deal, but its relevance to AdTech is indirect; still it impacts the broader tech infrastructure that supports advertising platforms.

Marvell to Acquire Lumentum in $115B All-Stock Deal
Marvell Technology has agreed to acquire photonics specialist Lumentum in an all-stock transaction valued at $115 billion including debt, with an equity value of approximately $102.5 billion. This marks one of the largest tech deals, surpassing Microsoft's acquisition of Activision Blizzard and Dell's purchase of EMC. Lumentum shareholders will receive 4.5 Marvell shares per share, representing a 23.9% premium. The combined company aims to lead in AI connectivity, capitalizing on the shift from copper to optical interconnects in AI data centers, with co-packaged optics projected to expand the addressable market to $550 billion. Marvell expects over $1 billion in annual cost synergies and positive EPS contribution in the first year after closing. Both boards approved unanimously, with Marvell CEO Matt Murphy retaining his role and Lumentum CEO Michael Hurlston joining the board. The deal, expected to close in the first half of 2028, faces shareholder and antitrust approvals. Market reaction was skeptical, with shares of both companies falling. Nvidia, which invested $2 billion in each company in March 2026, shares circular dealmaking concerns. This follows Marvell's earlier acquisition of Celestial AI.
Marvell shares tumble 8% after underwhelming outlook
Marvell Technology shares fell about 8% in premarket trading after the chipmaker raised its fiscal 2028 revenue outlook but failed to meet elevated investor expectations. The company reported fiscal second-quarter revenue of $2.7 billion, up 37% year-over-year and $39 million above guidance. Marvell now expects revenue to grow roughly 50% year-over-year to about $18 billion in fiscal 2028, up from a prior forecast of $16.5 billion, but provided limited detail on the outlook. Management said data-center demand remained strong, with data-center revenue accelerating 46% year-over-year. The stock’s momentum was also shaped by a recently announced partnership with Google that allows Google to buy up to 58.97 million Marvell shares at $206.58 each and covers products for Google’s TPU systems. Goldman Sachs analysts noted investor expectations were elevated heading into the quarter.
