Project delays and restructuring costs impacted results at Nordex Group last year, but the German-Spanish wind OEM was still able to meet its guidance, preliminary figures show.

Sales fell to €3.08bn ($3.8bn) in 2017 from €3.4bn in the previous year amid delays primarily to projects in South Africa, where state-owned utility Eskom delayed the signing of power purchase agreements.

Earnings before interest, taxes, depreciation, amortisation (Ebitda) and also before extraordinary costs fell to €242m last year from €285.5m
