FRANKFURT, Dec 9 (Reuters) - U.S.-based investor Ananym Capital has taken a stake in German power equipment Siemens Energy ENR1n.DE and is asking the group's management to review its struggling wind division, a person familiar with the matter said.
According to Ananym, a divestment or spin-off of the business could raise Siemens Energy's shares by around 40%, the person said.
Ananym was not immediately available for comment outside business hours.
Siemens Energy said in a statement that it "values constructive input for creating sustainable value for shareholders, employees, customers and partners," and that it addressed the development of its wind unit at a recent capital markets day.
