The only Greek shipowner listed in Oslo has been fast-tracked to a main board listing.

Euronext-owned Oslo Stock Exchange cleared the admission of Okeanis Eco Tankers' (OET) stock to the main board from Euronext Expand, the former Oslo Axess market.

It was given exemption from the requirement that a listed company must have been in existence for at least three years, because it has been trading for longer than that under different legal entities.
