Rafat broke the news Thursday that MVNO’s Virgin Mobile and Helio were considering a merger, and despite the WSJ verifying the tie-up with their own sources, SK Telecom (NYSE: SKM) said on Saturday that it was not in “any sort of talks” with Virgin and remained “committed” to the struggling Helio. According to Dow Jones, who quoted SK Telecom spokesperson Mina Ryu the report that the Korean telecoms company would buy Virgin Mobile (NYSE: VM) and infuse it with cash, and then Virgin Mobile would buy out Helio in an all-stock deal was “groundless.” She added, however, that SK Telecom is “actively seeking opportunities” to expand in the U.S. Reuters also reported that an unidentified source had said Virgin Mobile and SK Telecom were in “early talks” on a deal, but the person “who was not authorized to comment on the matter and asked not to be identified,” did not give any more detail on what that deal might be.
