Press Release

TeliaSonera announces cash offer for Eesti Telekom

TeliaSonera, the leading telecommunications group in the Nordic-Baltic region, today announced its decision to make a public offer for all the issued shares in AS Eesti Telekom that it does not already own. TeliaSonera presently holds 48.91 percent of the shares in Eesti Telekom.

TeliaSonera will, through its holding company Baltic Tele AB, offer EEK 111.30 in cash for each A-share and EEK 11,130 in cash for the B-share in Eesti Telekom, held by the Republic of Estonia. The offer value of the shares not already owned by TeliaSonera (51.09 per cent) is EEK 7,827 million (EUR 500 million). In addition the Supervisory Council of Eesti Telekom has approved the proposal of the Management Board of Eesti Telekom to propose a dividend of EEK 8.00 to the 2004 annual general meeting of Eesti Telekom. TeliaSonera expects that the dividend will be paid out to the shareholders prior to the end of the acceptance period for the offer. The offer price together with the dividend represents a premium of 12.3 percent over the volume-weighted average Eesti Telekom share price during the last twelve months.

The prospectus detailing the offer will be published after it has been approved by the Estonian Financial Supervision Authority (FSA). The printed prospectus will be made available at the Hansapank main branch at Liivalaia 8, Tallinn, Estonia.

The acceptance period for the offer begins on the date when the prospectus is published and will last for 42 days. The prospectus is expected to be approved by FSA and be published by the end of April at the latest.

The offer is conditional upon the offer being accepted to such an extent that TeliaSonera, through Baltic Tele, becomes the owner of not less than 85 percent of the total number of shares in Eesti Telekom. The offer is also conditional upon the approval of the Estonian Competition Board.

TeliaSonera will not increase the offer price.

TeliaSonera, through Baltic Tele, presently owns 48.91 percent of the shares in Eesti Telekom. The offer concerns the 27.23 percent owned by the Republic of Estonia and the 23.86 percent owned by other investors. The A-shares of Eesti Telekom are listed on the Tallinn Stock Exchange (HEX:ETLAT) and global depository receipts (GDRs) representing the A-shares of Eesti Telekom are admitted to the official list of the United Kingdom Listing Authority and to trading on the London Stock Exchange. A shareholder’s agreement relating to Eesti Telekom has prohibited TeliaSonera from acquiring more than 49 percent of the shares.

TeliaSonera has pursued its aim of strengthening TeliaSonera as the leading telecom operator in the Nordic and Baltic region. The transaction will represent the next step in the consolidation of the leading operators in the region. This offer is consistent with the strategy of taking advantage of opportunities for creating enhanced shareholder value.

The offer price reflects the assessed synergistic benefits that TeliaSonera expects to be able to extract as a result of the acquisition. Following the investment the transaction is expected to be both earnings and cash flow accretive. Synergies are expected to mainly come in the form of cost and capital expenditure synergies, of which the main savings areas are purchasing, product and service development and IT systems and infrastructure. Long term additional benefits are expected following the integration in the region and the development of the company.

“As stated before, our aim in our acquisition strategy is to build on or increase our strength in the Nordic and Baltic area. Achieving greater ownership in Eesti Telekom is a good example of that. We can increase our strength in the area and both companies stand to benefit. With Eesti Telekom and TeliaSonera on a common platform, private and business customers will gain in terms of service and a wider product range. I believe this will be important for the development of the increasingly integrated Nordic and Baltic region.” TeliaSonera’s CEO Anders Igel stated.

The Estonian Financial Supervision Authority has been notified of TeliaSonera’s decision to make an offer.
