WorleyPasons stock hammered after profit guidance cut WORLEYPARSONS slashed its profit guidance for the second time this year, sending its shares down 24 per cent and continuing a tough run for Australian engineering contractors as a long resources boom fades. Perth-based WorleyParsons blamed the downgrade on a faster-than-expected decline in its Australian business after construction work peaked at three giant natural-gas export facilities in Queensland. The deferral of oil sands projects in Canada, pressured by rising costs and a boom in shale oil production in the US, also weighed on the company's performance.
