Aggreko shares plunge as outlook disappoints Alongside that, Aggreko faces headwinds from Japan, reduced military work and will next year be without a boost from the Olympics. This year, Aggreko benefited from a £59m contract to power the games. "After a year of strong growth in 2012, the economic environment we will be facing in 2013 is particularly uncertain in many of our markets," the company said. Despite the difficult economic environment, Aggreko said that it expected its international power projects and local business to grow next year. Nonetheless, that growth is likely to be insufficient to mitigate entirely the reduction of £100m of revenue. Aggreko added that its 2012 performance was in line with expectations, with earnings per share expected to grow by at least 15pc. In October, Aggreko issued a profit warning, saying that bad debts and a currency hit would hurt its earnings.
