** Shares in Italy's INWIT INWT.MI rise 7% after a media report renews speculation of potential takeover bid involving investor firms Ardian and Brookfield
** French infrastructure fund Ardian is working with U.S.-based asset manager Brookfield on a joint takeover bid aimed at 100% of INWIT, financial daily Il Sole 24 Ore reports
** Ardian and INWIT declined to comment, while Brookfield did not immediately respond to a Reuters request
** Speculations of a takeover, in line with what was initially reported by French daily La Lettre in February, come after the stock plunged last week following a planned tower tie-up by clients TIM TLIT.MI and Swisscom's SCMN.S Fastweb
** "In this context, plans for a de-listing would run up against the lack of visibility on relationships with anchors," Intermonte says
** Both Intermonte and Equita cite "political and regulatory complexity" of any deal, potentially subject to Italy's Golden Power regulations
** Including Tuesday's rise, the stock is down about 14.6% YTD
