Lumentum (United States) 8-K

Summary

Marvell agreed to acquire Lumentum, an optical and photonic technology company, in an all-stock merger. Lumentum stockholders will receive 4.500 Marvell shares per Lumentum share; the transaction values Lumentum at an implied $115B enterprise value, or approximately $1,132 per share, a 23.9% premium to the companies’ unaffected 10/28/2026 closing prices. After closing, Marvell stockholders are expected to own approximately 67% of the combined company and Lumentum stockholders approximately 33%.

The companies are combining Marvell’s interconnect, switching and custom silicon with Lumentum’s lasers, optical transceivers, optical circuit switching and specialized manufacturing to build an integrated connectivity portfolio for increasingly complex artificial intelligence infrastructure. They expect the combination to expand the combined company’s total addressable market to $550B and to close in the first half of calendar 2028, subject to stockholder and regulatory approvals and other customary conditions. Marvell also said preliminary Q3 FY2027 revenue was consistent with its prior outlook; it maintained the midpoint while narrowing the outlook range.

Key Figures

• The companies expect more than $1B in annual run-rate cost synergies, primarily from cost of goods sold, and expect the merger to be accretive to Marvell non-GAAP EPS in the first year after closing. They also expect it to improve the combined company’s long-term revenue growth and non-GAAP gross and operating margin profiles.
• Illustrative most-recent-quarter annualized figures: Marvell revenue of $12.6B, Lumentum revenue of $5.1B and pro forma revenue of $17.7B, excluding synergies. Non-GAAP gross margins were 58%, 53% and 57%, respectively; non-GAAP operating margins were 37%, 42% and 39%. Marvell figures use the FQ3 FY2027 guidance midpoint, based on its 8/27/2026 outlook; Lumentum figures are for FQ1 FY2027.
• Lumentum cited a 20x increase in indium phosphide wafer-fab unit volume over two years and billions of vertical-cavity surface-emitting lasers served. Marvell said it has shipped billions of products and secured capacity to support growth.
• Standard termination fees are $5.8B payable by Marvell to Lumentum and $2.9B payable by Lumentum to Marvell in specified circumstances. Marvell also owes Lumentum a $3.2B regulatory termination fee in specified cases involving failure to close because of regulatory approvals or restraints.
• In connection with the merger, Lumentum entered into a tax reimbursement agreement with CEO Michael Hurlston and approved similar agreements for other named executive officers as needed or advisable. If mitigation strategies leave specified excess tax liabilities or Section 4999 excise tax, the company will make a payment intended to place the executive in the same after-tax position as if the excise tax did not apply; the agreements become void if the merger agreement is terminated.
• Marvell CEO Matt Murphy will remain chairman and CEO of the combined company. Three Lumentum directors, including CEO Michael Hurlston, are expected to join Marvell’s board.

Guidance

• Marvell Q3 FY2027 revenue outlook: midpoint maintained; range narrowed to ±2% around the midpoint, from ±5%.

Investor Takeaways

• Watch for stockholder votes and regulatory clearances as milestones toward the expected first-half 2028 closing.
• The combination’s financial case depends on realizing more than $1B in annual run-rate synergies and achieving expected first-year non-GAAP EPS accretion at Marvell.
• Track customer adoption and production scale for integrated optical connectivity solutions across data-center and package-level applications; continued manufacturing expansion would support the companies’ plan to meet rising AI infrastructure demand.
