Warren Buffett's Berkshire Hathaway hikes its SiriusXM stake to 32% after Liberty deal

Warren Buffett's Berkshire Hathaway continued to increase its stake in SiriusXM, now owning 32% of the New York-based satellite radio company.

The Omaha, Nebraska-based conglomerate purchased roughly 3.6 million shares for about $87 million in separate transactions Wednesday through Friday, according to a filing with the Securities and Exchange Commission late Friday.

Berkshire hiked its bet after billionaire John Malone's Liberty Media completed its deal in early September to combine its tracking stocks with the rest of the audio entertainment company. It was part of Malone's reshuffling of his sprawling media empire that also included a split-off of the Atlanta Braves baseball team into a separate, publicly traded company, which Berkshire also owns shares in.

The 94-year-old has never mentioned the bet publicly, and it's unclear if he's behind it or if it's the work of the billionaire's investing lieutenants, either Ted Weschler or Todd Combs.

SiriusXM, which has been grappling with subscriber losses and unfavorable demographic shifts, is not a popular stock on Wall Street. Out of the 14 analysts covering the name, only five gave it a buy rating, according to FactSet.

Meanwhile, the Liberty transaction, which reduced share count by 12%, could cause the company to pause stock buybacks until 2027, which will likely
