The two groups are expected to submit their final bids, which may value the mobile operator at more than EUR 3 billion, on 15 February. DT may, however, opt to keep the business if it fails to get an acceptable price, one of the sources said. Liberty Global dropped out of the bidding for T-Mobile, in order to pursue talks on a joint venture with Vodafone in the Netherlands, the report said. Other initial bidders such as buyout groups Apax and CVC have also dropped out, according to Reuters' sources. Deutsche Telekom is hoping get at least EUR 3.6 billion or about 8 times expected annual EBITDA of EUR 450 million for T-Mobile.
