Siemens Gamesa lowers earnings outlook on deferrals, delays, costs

MADRID, April 30 (Reuters) - Wind turbine maker Siemens Gamesa warned on Friday it could earn less this year than previously expected, trimming 700 million euros ($842 million) off the top end of previous revenue guidance.

The leading producer of offshore generators now expects full year revenue of 10.2-10.5 billion euros, having previously said it expected to 10.2-11.2 billion euros.

It maintained guidance for an operating margin over sales before interest, tax, and some other costs, of 3%-5%.

This change was driven by project deferrals, execution delays, higher costs of raw materials and a lower contribution from its offshore division, the company said in a stock market filing. ($1 = 0.8311 euros) (Reporting by Isla Binnie, editing by Andrei Khalip)
