UPDATED: John Malone’s company will give Wall Street a lot to talk about today. Shares in Liberty-controlled Sirius XM are already up about 2% in pre-market trading after it said that it will add $2B to its share repurchase program, which will include a buy-back of $500M worth of Liberty’s stake. That will leave the media holding company with 52% of the satellite radio service. In addition to that deal, Liberty says it recently completed a transaction to recover 6.3M of its shares that Comcast held. In return for its stock, the cable giant picked up Leisure Arts Inc, $417M in cash, and Liberty’s rights to a revenue-sharing deal with CNBC. Liberty also says that it will sell $500M in debt to help it pay off what it calls “privately negotiated cash convertible note hedge and warrant transactions.” It warns that the process of unwinding those deals “could have the effect of decreasing the trading price” of Liberty’s stock. In addition to all that, Liberty Interactive — a separate company that Malone controls — said that it will create a tracking stock for QVC (along with its 38% interest in HSN), and spin off its 57% voting stake in TripAdvisor. The new company will be called — what else? — Liberty TripAdvisor Holdings. The transactions are complicated and expected to be tax-free — characteristics of most Malone deals. Investors will hear more about these and other matters at an annual briefing today where execs from Liberty, Sirius XM and Charter Communications are scheduled to speak.
