In July 2015, Tassal Group Limited (Tassal) announced the acquisition of De Costi Seafoods Company (De Costi) in a combination deal of cash and shares. The acquisition would allow Tassal to address a A$4.3 billion Australian seafood market that was much larger than the previously addressable salmon market of $700 million. Tassal had previous experience in species diversification. However, the environmental impacts of its major operations in Macquarie Harbour had been under the scrutiny of the Australian authority. Given the critical harbour issues, should Tassal continue to expand overseas? What were the motives to acquire De Costi? Did Tassal have sufficient capabilities and resources to cope with the high demand for Tasmanian salmon, particularly in the Asian market?
