Mrvl is acquiring Lite, with the former holding 10% and the latter 10%. If this acquisition succeeds, the competitive landscape of the optical interconnect industry will be reshaped. This explains Mrvl's path to trillions of dollars. Why did the former's stock price drop while the latter's rise? Mrvl, as the acquiring party, pays for the acquisition. Large transactions often use stock (or a portion of stock) as payment, and issuing new shares dilutes existing shareholders' equity and also incurs integration risks. Lite, as the acquired party, typically requires a premium for shareholder approval. This is a typical market reaction of "buyer to buyer" after a major merger announcement.
