North West firm Halliwells has secured a significant deal advising Natural Gas Shipping Services (NGSS) on its takeover by oil giant Gazprom. NGSS was purchased by Gazprom Marketing & Trading (GM&T), the UK arm of Gazprom. This is the second time Halliwells has acted on such a transaction - it represented NGSS's sister company Pennine Natural Gas when it was purchased by GM&T last year. Charles Glaskie, the partner that led the Halliwells team that worked on the deal, said: "We paved the way for this acquisition when advising Pennine Natural Gas last year. NGSS are existing clients of ours and we've done a lot of work for them, including commercial and corporate advice as well as day-to-day work." Glaskie added that the transaction was Gazprom's first all-share acquisition of a UK company. Hunton & Williams advised GM&T on the transaction.
