Shares in Rockrose Energy were today readmitted for trading on the London Stock Exchange.
Rockrose’s entire issued share capital comprises 15.3million ordinary shares.
They were up 207.09% to £3.90 in early trading.
Listing of the North Sea oil firm’s shares was suspended in October when it announced a reverse takeover of Idemitsu Petroleum UK.
The acquisition, which closed in December, gave Rockrose stakes in 10 North Sea oil fields.
Last month, the company revealed its efforts to buy stakes in the Scott and Telford fields from Maersk Oil were dead in the water.
