Coherent has again determined that a revised acquisition proposal from II-VI is superior to terms of an amended merger agreement with Lumentum. Coherent has informed Lumentum that it intends to terminate that merger agreement, into which the companies entered on March 9 (announced on March 10), should it not receive an amended agreement. Terms of the new II-VI proposal, which is the fourth that Coherent has confirmed from II-VI, dictate that Coherent shareholders would receive $220 in cash and 0.91 of a share of Coherent common stock for each Coherent share. The deal is worth approximately $7 billion. The latest II-VI offer is in response to Coherent’s confirmation that it received, and that its board was considering, a revised offer from Lumentum. Per that fifth confirmed offer from Lumentum, the company would acquire Coherent in a $6.9 billion deal. Each share of Coherent common stock would be exchanged for $220 in cash and 0.61 of a share of Lumentum common stock. The Coherent board also determined that the latest II-VI proposal is superior to the revised acquisition proposal that Coherent received from Lumentum on March 17. Coherent notifed Lumentum that it intends to terminate their merger agreement unless Coherent receives a revised acquisition proposal from Lumentum by March 22 that the Coherent board determines to be at least as favorable to Coherent's stockholders as II-VI’s revised proposal.
