Australia's second-largest gas producer Santos said on Monday it intended to support an all-cash $18.7 billion takeover bid from an international consortium led by Abu Dhabi's National Oil Company (ADNOC),

A consortium led by Abu Dhabi National Oil Company (Adnoc) has launched an all-cash US$18.7 billion takeover bid for ASX-listed energy company Santos.

Santos said XRG, an investment arm of the Abu Dhabi National Oil Company, had made an indicative cash offer of $5.76 a share, valuing the Adelaide-based company at $18.7bn. It represents a 28 per cent premium to Santos’s closing share price last week.
