Danish wind turbine manufacturer Vestas has posted another quarterly loss, due to extraordinary warranty on a “considerable number of blades”, and re-introduced a guidance for all of 2020, expecting a lower profitability than seen earlier this year.

Earnings before interest and taxes (Ebit) and special items plunged to €34m ($40m), from €128m in the second quarter of 2019.

The decrease was driven by increased cost levels derived from warranty provisions as well as logistical challenges and supply-chain bottlenecks, amplified by the Covid-19 situation.
