TeliaSonera requests interim measures on Turkcell Holding shares

On March 25, an agreement was announced in which Cukurova agreed to sell all its shares in Turkcell Holding to TeliaSonera for USD 3.1 billion (SEK 23.7 billion). Cukurova has thereafter refused to sign a final share purchase agreement. TeliaSonera believes that Cukurova is still required to complete the transaction and pursued legal actions to protect its rights. TeliaSonera has filed a request for arbitration at the International Court of Arbitration of the International Chamber of Commerce. The arbitration will take place in Geneva. TeliaSonera has now also filed a request for interim measures at a Civil court in Geneva. Due to the high requirements for interim measures, the outcome of the proceedings is uncertain, but they are requested to further protect TeliaSonera’s rights. In light of the recent development, including official communication from Cukurova that the company is negotiating financial schemes with Russian Alfa Group, TeliaSonera is asking the court to prohibit Cukurova to initiate or continue contacts with third parties other than TeliaSonera, with a view to sell or pledge shares in Turkcell Holding. An update on the situation in the Turkcell and Eurasia will be done during a telephone conference later today with Anders Igel, TeliaSonera’s President and CEO and Erdal Durukan, President of Fintur Holding and vice chairman of Turkcell.
