Shares in Brazilian infrastructure company CCR S.A. (BOVESPA:CCRO3) soared on December 6, 2021 after a newspaper said Canadian pension fund Caisse de d?p?t et placement du Qu?bec (CDPDA.UL) is looking to buy conglomerate Andrade Gutierrez's stake in the firm. O Globo columnist Lauro Jardim reported on December 5, 2021 that CDPQ mandated two banks - Bank of America Corporation (NYSE:BAC) and Banco Santander, S.A. (BME:SAN) - for the deal, adding that the pension fund also aims to potentially take the company private in the future. XP added that the possibility of CDPQ taking CCR private could represent an upside to minority shareholders due to tag-along rights. CCR did not immediately respond to Reuters request for comments. Andrade Gutierrez and CDPQ declined to comment.
