The Transaction comprises all operations in the mentioned regions, which are valued at a total Enterprise Value (EV) of NOK 10.2 billion on a cash- and debt- free basis, assuming a normalised level of net working capital. The Transaction will take place by transfer of the shares in Grieg Seafood Finnmark AS, Grieg Seafood Newfoundland AS and Grieg Seafood Canada AS to Cermaq.
