Keeping this extremely high-level. It seems to me that LSXMK is trading at an usually wide-discount to NAV, despite several possible catalysts over the coming quarters. Discount to NAV currently stands at ~35% to NAV. You have small stakes in the Braves, Formula One, iHeart, and a sizable position in Live Nation. The jewel however is the tracking unit of Sirius which has gone from 45% of O/S from GFC in 2009 to ~77% today. You have Sirius actively buying back stock, as well as Liberty buying back the tracker at a deep discount. Liberty which owns ~77% of Sirius will likely acquire ~80% of the company through natural buybacks over the next several quarters. In fact earlier this year, both companies filed with the SEC to potentially have a consolidated tax forum. Basically over the coming quarters it is likely that Liberty will acquire all of Sirius and this arb to NAV will collapse. There are many theories and possible outcomes, but I'll save this for the Q&A below. Apologies as I know a lot has been written about Liberty series before - but I didnt find a separate thread on the Sirius tracker.
