Engineer and project manager AMEC is on the slide. It reported a slight fall in pre-tax profits due to one-off items but said trading remained robust in a tough trading environment. In the six months to June 30, pre-tax profits fell 4% to £88.4m, as revenues edged up slightly to £1.260bn from £1.255bn. A 4% drop in full-year profit at Diageo was pretty much in line with expectations, but the alcoholic drinks giant has cut current year growth targets. The group, responsible for the Smirnoff, Captain Morgan and Guinness brands, said pre-tax profit fell £78m to £2.015bn in the year ended 30 June on reported sales up 15% to £12.28bn. Net sales rose to £9.31bn from £8.09bn.Miner Kazakhmys surprised the market with an upbeat trading statement in which it said its copper production is expected to exceed the company's annual target of 300 kt given additional 15 kt produced from stockpiled material. Kazakhmys saw half-year pre-tax profits slide to $645m from $886m on revenues that dived to $1,648m from $2,838m the year before.
