CL, unlike TBRA, Amda has significant customer relationships in Weigao, NGK, Dentsply, Morgan, etc..
Not only that but there will be goodwill generated from Synergy of Z&A. DP60 post in my collection of posts covers this further.
The price of Amedica will be determined by IPR&D + Customer Relationships (425+m order just for Weigao) + Synergy = acquisition price.
