The controversial Aegean Marine Petroleum Network (AMPN) takeover of a company owned by founder Dimitris Melissanidis has been terminated.
The US-listed bunker and tanker group said that the necessary approvals had not been gained before the contractual deadline of 27 March.
Aegean agreed last month to buy ship waste management firm HEC Europe for $367m.
Last week, the company and three activist shareholders launched settlement talks aimed at ending litigation over the transaction.
