Russian operator Vimpelcom’s plans to offload its mobile towers in Moscow is still on track, TMT Finance reports, with a series of prospective buyers expressing an interest in the portfolio. Sources told TMT that there has been interest from several infrastructure-focused groups, as well as a number of financial sponsors, including one bid backed by a Russian billionaire, and another joint venture, part-funded by Macquarie. Barclays Capital is advising Vimpelcom on the transaction. Although the mobile giant has targeted a deadline of 4Q13 for the sale, sources suggest that it is likely to drag on into 2014 due to legal issues. The source told TMT: ‘The commercial logic is there and there’s clear motivation due to the big wave of investment needed for 4G and data services. There has been interest from financial and infrastructure players. Higher returns are needed for financial players, so infrastructure players have are likely to have the upper hand’.
