ArcelorMittal, the world's largest steelmaker, is considering the sale of its stake in Luxembourg-German utility Enovos, a spokeswoman for the Luxembourg government said on Thursday.

ArcelorMittal has informed us that it is reviewing assets that it does not consider as core businesses and is also looking at Enovos, the spokeswoman for the Ministry of Economy and Foreign Trade said.

A spokesman for ArcelorMittal declined to comment.

ArcelorMittal has a 25.3 percent stake in the company, which has an expected annual turnover of 2.5 billion euros ($3.69 billion). The Luxembourg government holds 28.3 percent.

Other shareholders include GDF-Suez unit Electrabel, German utilities E.ON and RWE, and Luxembourg state-owned investment group SNCI.

The spokeswoman said ArcelorMittal had informed Enovos shareholders -- who have first rights to buy stakes of partners -- that it was considering selling the stake, stressing however that the steel giant had not yet decided whether to sell.
