Tsiana's press service said the company has yet to receive a formal offer from T-Technologies to acquire up to 100% of the shares, RBC reports. The representatives of the service stated that the buyer's initiative in itself does not mean that the transaction is completed. The board will review the proposal upon its official receipt. Earlier, T-Technologies sent an offer to the Bank of Russia to purchase Tsyana securities at 993.05 rubles per share at a premium of 29.3% to the market price.
