Mattera Jr., CEO of II-VI said “Together, we will have significant opportunities to accelerate our growth through complementary technology platforms, strengthen our competitiveness by using our combined scale across the value chain, benefit from deeper market intelligence and expertise, and further diversify our businesses by end market and geography.”

II-VI plans to finance the transaction with cash on hand, approximately $5.4 billion in fully committed debt financing from J.P. Morgan Securities LLC and an equity investment from Bain Capital.

With Bain Capital’s investment, co-chairman Steve Pagliuca, is expected to join the II-VI board. Two current Coherent directors are also expected to join the II-VI board upon closing.
