   Marvell Announces All-Stock Purchase of Lumentum

   Marvell Technology announced an all-stock acquisition of Lumentum Holdings in a massive bet on artificial intelligence data center infrastructure and optical connectivity. While Reuters, CNBC, and Yahoo Finance report a value of $115 billion for the transaction, the Wall Street Journal reports an $80 billion deal figure. The deal is structured entirely in equity, meaning Lumentum shareholders will receive Marvell stock rather than cash. The combination targets optical networking technologies to support booming artificial intelligence workloads, but the agreement has immediately sparked intense scrutiny from analysts and investors questioning the valuation and timing.

   Why it matters

   Mega-mergers in the semiconductor and optical networking sectors carry high stakes as companies race to capture market share in artificial intelligence hardware infrastructure. The transaction represents a major test of equity-based deal structures amid broader market skepticism. Legal and financial experts are raising questions about the immense valuation, potential governance concerns, and the overall timing of such a massive technology agreement.
