LONDON — Oilfield services company Hunting Plc said it expected a 50 percent to 75 percent fall in operating profit for the year as it continued to reel under a drop in global rig counts and a weak oil and gas market. Hunting shares fell more than 7 percent on the London Stock Exchange on Thursday morning. The stock was the top loser on the FTSE-250 midcap index. The company, which provides services and equipment for drilling, completing and maintaining oil and gas wells, said operating profit slumped 76 percent in the first five months of the year. “The market appears to have deteriorated more and the key continues to be when or indeed if, the U.S. business starts to pick up,” analysts at Barclays wrote in a note. London-based Hunting said it had cut 25 percent of its workforce since the start of the year, resulting in savings of about $41 million. In some of its divisions, the job cuts were as much as 50 percent, the company said. — Reuters
