Siemens Gamesa accumulated the baggage of a near-$1bn loss this year as the wind turbine giant streamlines its structure ahead of potential integration into majority owner Siemens Energy.

Persisting supply chain disruptions, heightened by geopolitical tensions and additional waves of Covid-19, as well as upward pressure on the price of materials and shipping, weighed heavily on results during the company’s fiscal year 2022 that ended in September.

Revenue fell 3.8% to €9.81bn ($9.81bn) in fiscal 2022 from a year earlier, while the earnings margin before interest and taxes (Ebit) pre-PPA and integration and restructuring (I&R) costs – a measure of profitability – went down five more percentage points to -5.9%.
