The Abu Dhabi National Oil Company's gas processing firm said Friday it plans to sell 4 per cent of its shares to local investors in the latest initial public offering to be made by a state-run energy company in the Middle East. The move follows a similar IPO by the Saudi oil giant Aramco in 2019 that raised some $30 billion, and comes months before the United Arab Emirates is set to host this year's U.N. climate talks.
