The merger would have seen the combined Mermaid Marine/P&O Maritime Services entity listed on the Australian Stock Exchange under the brand name P& O Marine, with DP World owning over 60% of the merger company.
Mermaid Marine said last week its financial performance had substantially exceeded expectations and it believed the agreed merger ratio was no longer appropriate.
DP World ,however, said the deal as originally agreed eight weeks ago was fair, having been arrived at after extensive negotiations and due diligence by both parties. It said it had been given no information to change its view since then.
The company added that the proposed merger was a good fit for both companies, and would have allowed the two to explore new markets; the company continued to believe in the strategic value of the merged entity. However, it said P&O Maritime Services was a strong business and DP World was equally comfortable supporting it to expand on its own.
