The share price of oil and gas services and equipment provider Neptune Marine Services surged 30 per cent on Tuesday after its major Singapore-based shareholder made a takeover offer. MTQ Corporation subsidiary Bloossomvale made the 3.2¢ per share offer, a 33 per cent premium to Monday’s trading price, valuing the company at just under $60 million. Patersons Securities says the offer is close to a fair price based on forecast 2013 earnings before interest and tax of $7.4 million. Neptune has advised its shareholders to take no action. The company has previously suffered from negative cash flow, which triggered a restructure of the Perth-based resources provider earlier this year. Several of its loss-making businesses were sold, with the company targeting much of its growth plans on deals connected to Gladstone’s $70 billion liquefied natural gas boom in Queensland along with new work in Victoria’s Bass Strait.
