I have listened to the CC of IIVI on the buyout and I believe 3d sensing + VCSEL + Lidar is the key reason for the combined company. The CFO emphasized that investors don't realize how big the 3d sensing market would become and facial recognition is but a small part of the total future market that includes LIDAR and various automotive applications.
For Aixtron shareholders, MOCVD for 3d sensing will only continue to grow to address the market demands. One interesting question is would the combined company scare off the Chinese companies beginning to get into this space. All the major Chinese LED companies like Sanan, Changelight, etc are moving into this space. I have stated that I believe China will build her own epiwafer+vcsel+lidar+5G+EV capability using the national power. She has no choice because Trump is choking China. Therefore, this latest development would not scare off the Chinese but only would intensify the competition by the Chinese make China to fight off the american. On that theory, Aixtron would benefit.
