Interesting to note that this deal is already being investigated by a law firm as to it's fairness to shareholders.

"On November 4, 2021, NeoPhotonics announced that it had entered into an agreement to be acquired by Lumentum in a deal worth approximately $918 million. Pursuant to the merger agreement, NeoPhotonics stockholders will receive $16 in cash for each share of NeoPhotonics common stock owned.   The deal is scheduled to close in the second half of 2022.

Bragar Eagel & Squire is concerned that NeoPhotonics’ board of directors oversaw an unfair process and ultimately agreed to an inadequate merger agreement. Accordingly, the firm is investigating all relevant aspects of the deal and is committed to securing the best result possible for NeoPhotonics’ stockholders"
