Engie is working with advisers to pursue a deal for the U.S.-based electrical and mechanical construction and facilities services firm, according to the report.

No final decision has been made and the French company may decide against the offer, Bloomberg said https://bloom.bg/2DqCyGL.

Earlier this month a consortium led by Engie won a bid for Petrobras' TAG pipeline arm with an $8.6 billion offer, in a bid to boost the company's presence in the fast-growing Brazil market.

Neither Engie nor Emcor immediately responded to Reuters' request for comment.
