pre_text: Order intake increased in all businesses year-over-year due to a higher volume from large orders. Sharp order growth in Asia, Australia included two large orders for offshore wind-farms including service in Taiwan totaling € 2.3 billion. SGRE also recorded sharply higher orders in the Americas region, driven by several large orders in the onshore business mainly in the U. S. In contrast, orders came in substantially lower in the region Europe, C. I. S., Africa, Middle East which in the prior year had included an order for an offshore wind-farm, including service, in the U. K.
  worth € 1.3 billion. Revenue was up significantly year-over-year, with substantial growth in the offshore and service businesses and clear growth in the onshore business. On a geographic basis, revenue rose substantially in Europe, C. I. S., Africa, Middle East, while it declined clearly in the other two reporting regions. Adjusted EBITA was on the prior-year level as positive effects from productivity improvements and higher revenue were offset by price declines, a less favorable project mix and higher expenses for integration costs and capacity adjustments including severance. Severance charges were € 32 million in fiscal 2019 and
  € 77 million in fiscal 2018. SGRE’s order backlog was € 26 billion at end of the fiscal year, of which € 9 billion are expected to be converted into revenue in fiscal 2020. These results were achieved in markets that grew substantially in fiscal 2019 in terms of installed capacity due to higher demand in both the onshore and offshore markets, with the latter growing faster. Market volume in euros was subject to adverse price development. On a regional basis, growth in the onshore business was again driven primarily by China where the largest national wind market in the world for onshore generation remains largely closed to foreign manufacturers, and secondarily by the
  U. S. In contrast, the onshore market in Germany declined significantly. In the offshore market, growth was driven by the U. K. and China. SGRE expects global onshore wind installations to grow clearly in fiscal 2020, driven by growth in the U. S. and India. Global offshore wind power markets are expected to grow in fiscal 2020. The driver of this growth is China which offsets a slight decline in European markets. Market volume in euros is expected to be subject to adverse price development in the offshore business, reflecting the trends discussed above, and currency translation effects.
