Norwegian ferry group Fjord1 has posted another increase in profit ahead of an Oslo IPO.

Pre-tax profit was NOK 97m ($11.29m), against NOK 35m in 2016, it said.

Revenue grew to NOK 637m from NOK 533m.

TradeWinds reported last month that Fjord1 is planning to list the company on the Oslo Stock Exchange.

Majority owner Per Saevik and his company Havilafjord, which have a 67% stake, plan to list 49% of the Fjord1 shares.
