Marvell's optical deal looks dangerously myopic
MRVL•Marvell is reportedly in advanced talks to buy Lumentum, a deal that could cost about $108 billion assuming a 30% premium. Analysts estimate potential synergies of $1.1 billion, but the resulting 6% return would be below Lumentum's 10% cost of capital.
1. Strategic rationale
Marvell Technology is reportedly eyeing a deal to buy Lumentum Holdings, which would expand its control of the data-center supply chain and strengthen its position in AI networking against Broadcom. Lumentum makes optical components that transmit data using light, and its shares have risen 370% in the past 12 months.
2. Supply constraints
Lumentum CEO Michael Hurlston has said some products are sold out into early 2029, and the company cannot meet about 70% of orders for some offerings through next year. Bernstein expects optical demand to exceed supply through 2028, while potential U.S. restrictions on Chinese rivals could further tighten inventory.
3. Deal economics
Assuming a 30% premium to Lumentum's share price before reports of talks, a bid would be approximately $108 billion. Potential synergies of $1.1 billion, combined with Lumentum's forecast $6.8 billion of operating profit in 2029, imply a 6% return after tax, below its 10% cost of capital, Morningstar analysts estimate. The article also flags the risk that optical shortages could ease, along with customer conflicts and the demands of a more manufacturing-intensive business. Marvell has lost about $28 billion in market value since the talks were reported.
