Gina Rinehart-owned Hancock Energy said on Monday that its updated A$0.36 per share offer for Australia’s Warrego Energy (WGO) , which valued the oil and gas explorer at A$440 million ($304 million) has received the minimum required 40% approval from Warrego shareholders. As a result, all Warrego shareholders who accepted Hancock’s offer will now receive A$0.36 cash per share, regardless of when they accepted the offer, said Hancock. Warrego, which holds the West Erregulla gas fields in North Perth Basin in Western Australia, has been at the center of M&A battles, attracting offers from players such as Beach Energy (BPT) , Strike Energy (STX) and Hancock Energy. Hancock said that it is now the controlling shareholder of Warrego, holding more than 50% of all Warrego shares.
