The Aberdeen-based company left the Alternative Investment Market in 2018 when it was bought by Israeli conglomerate Delek Group. Last year it was revealed that Delek is mulling a return for Ithaca to the London stock market and today confirmed it is continuing to consider its options, including an initial public offering (IPO). Ithaca completed its £1.6 billion takeover of assets from Chevron North Sea in November. Oil giant BP invested $50 million (£38 million) into Ithaca last month.
