Why did BofA downgrade Marvell?

  • BofA downgraded Marvell from Buy to Neutral and cut its price target from $400 to $225, while maintaining its earnings forecasts. The bank believes the all-stock acquisition of Lumentum could weigh on the share price for a prolonged period, and industry valuation multiples have recently contracted.
  • The new price target uses a 20 times expected price-to-earnings multiple for calendar year 2028, after accounting for stock-based compensation expense, down from 33 times previously; the Philadelphia Semiconductor Index fell 19% in the month before the report was published.

Which parts of optical connectivity could the combination bring together?

  • BofA recognizes the deal's strategic value: Lumentum's lasers, optical circuit switches, optical transceivers and indium phosphide manufacturing capabilities can be combined with Marvell's digital signal processors, transimpedance amplifiers, drivers, silicon photonics and switching businesses to create a broader electrical-to-optical connectivity platform.
  • Both companies benefit from AI demand. BofA expects the combined company's potential market to reach $550 billion in calendar year 2030, with new opportunities coming mainly from near-packaged optics, co-packaged optics and emerging scale-up connectivity; Lumentum has also announced that it secured a second major near-packaged or co-packaged optics program, expected to generate more than $5 billion in revenue.

Why might complementary businesses not lead to earnings per share accretion?

  • BofA estimates that the all-stock deal will increase the share count by approximately 50%. Based on market consensus estimates, the bank calculates that even if approximately $1.1 billion in cost synergies are achieved, the additional profit would struggle to offset the dilution of earnings per share from the larger share count.
  • In a scenario without revenue synergies, the combined company's earnings per share for calendar years 2029 and 2030 would be 10.5% and 14.7% lower, respectively, than Marvell's on a stand-alone basis; even with approximately 5% in revenue synergies, they would still be 7.0% and 12.4% lower, respectively.

How else could the deal affect existing businesses?

  • Marvell has supplied processors, amplifiers and drivers to numerous optical module manufacturers; Lumentum supplies lasers and also competes with those manufacturers in the optical transceiver market. BofA therefore worries that customer or channel conflicts could arise after the merger.
  • Marvell expects the deal to close in the first half of calendar year 2028. BofA believes the approval process could be lengthy, including regulatory procedures in China; until closing, regulatory and financial risks could continue to affect the share price.
