Sonangol EP is interested in buying a 25% stake held by Brazilian telecommunications group Oi S.A. (BOVESPA:OIBR4) in Unitel S.A., the chairman of the Angolan state company told Portuguese weekly Expresso. The Oi Group, which owns PT Ventures, a shareholder of Unitel, is undergoing a legally imposed business recovery process, which has sought to sell its shareholding in the Angolan company, in order to raise significant funds. The president of Sonangol, Gaspar Martins, told the weekly that the company is analysing the possibility of acquiring the stake, but added that the move depends on the final decision of the Paris Arbitration Court. Sonangol would be entitled, if it acquires Unitel, to approximately $1 billion in dividends.
