Marvell Technology 8-K

Summary

Marvell agreed to acquire Lumentum in an all-stock deal, combining their electrical and optical technologies for AI connectivity. Lumentum shareholders will receive 4.500 Marvell shares per share, implying a $115B enterprise value and a 23.9% premium to Lumentum’s unaffected 10/28/2026 closing price. Closing is expected in 1H CY2028, subject to shareholder and regulatory approvals and customary conditions.

The companies see integrated optical connectivity as a response to growing bandwidth needs and the limits of copper as AI systems scale. Separately, Marvell’s preliminary Q3 FY2027 revenue remained at the midpoint of its prior guidance, with the expected range narrowed.

Key Figures

• Marvell brings electrical and optical interconnect, switching and custom silicon; Lumentum adds high-performance lasers, optical transceivers, optical circuit switching and specialized compound-semiconductor manufacturing. The combined portfolio is intended to support co-designed connectivity from distributed data centers to connections within semiconductor packages.
• On an annualized most-recent-quarter basis, the presentation showed pro forma revenue of $17.7B, excluding synergies, with non-GAAP gross margin of 57% and non-GAAP operating margin of 39%. Marvell’s contribution used the midpoint of its 8/27/2026 Q3 guidance.
• The companies cited a line of sight to more than $1B in annual run-rate cost synergies, primarily in cost of goods sold, and expect the deal to be accretive to Marvell non-GAAP EPS in the first year after closing.
• The presentation put the expanded combined total addressable market at $550B by CY2030. Current Marvell shareholders are expected to own approximately 67% of the combined company and Lumentum shareholders approximately 33%, on a fully diluted basis.
• Matt Murphy will remain Chairman and CEO; three Lumentum directors, including CEO Michael Hurlston, are expected to join Marvell’s seven-member board.

Guidance

Investor Takeaways

• Watch for Marvell’s and Lumentum’s shareholder votes and regulatory approvals; these determine whether the expected 1H CY2028 closing proceeds.
• After closing, progress toward more than $1B in annual run-rate cost synergies and the stated first-year non-GAAP EPS accretion will test the financial case for the combination.
• Watch whether the combined teams bring co-designed optical solutions to customers at scale, the commercial premise behind combining Marvell’s connectivity technologies with Lumentum’s photonics and manufacturing capabilities.
