Aggreko sees challenging 2016, warns on lower returns

LONDON, Aug 6 (Reuters) - Aggreko (LSE: AGK.L - news) , the world's largest power provider, said it expected trading in 2016 to remain difficult, with margins and returns set to be lower due to a restructuring following a profit warning last month.

The British firm, whose kit powers major events and covers electricity shortfalls, said it had implemented a new organisation structure focused on better addressing its troubled markets and improving operational efficiency.

"2016 will be a year of change in the business with markets remaining difficult; margins and returns are likely to be lower in the short term," it said.
