"The main drivers of the positive business developments have been improved freight rates as well as rigorous cost and revenue management," said the company, the world's fifth biggest operator, in a statement on preliminary results.

Operating earnings before interest and taxes (EBIT) had previously been pegged in a target corridor between 0.5 billion and 0.9 billion euros.

Earnings before interest, taxes, depreciation and amortisation (EBITDA) rose to 1.99 billion euros from 1.14 billion in 2018 and compared with a target corridor of 1.6 to 2.0 billion.

Freight rates, a key measure in shipping, rose by 2.6% year-on-year to $1,072 per twenty foot equivalent unit (TEU).

Hapag-Lloyd is due to give a 2020 guidance when it publishes full annual results on March 20.
