The company declined to comment when Bloomberg reported on 15 May it was considering a range of options to meet its "growing cash needs".
Unnamed sources told the financial newswire that negotiations may or may not lead to a transaction.
The developer has since stated the report was "subject (to) misinformation" and that "there are no negotiations of the sale of company shares of the German wind farm developer".
A spokesman added: "The dissemination of false or misleading information is also not relevant by frequent repetition. We would like to conclude the subject with it."
