Warren Buffett’s Berkshire Hathaway hikes SiriusXM stake to 32%

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-based conglomerate purchased roughly 3.6 million shares for about $87 million in separate transactions Wednesday through Friday, according to a filing with 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.

Buffett’s firm first bought Liberty Media’s trackers in 2016 and started piling into Siri’s tracking stocks in the beginning of 2024 after the deal announcement in a likely merger arbitrage play.

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.

Not well loved

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 stock, only five gave it a buy rating, according to FactSet.

JPMorgan analyst Sebastiano Petti reopened coverage of SiriusXM with an underweight rating last week, citing concerns about the radio giant’s long-term growth and its ability to successfully target a broader demographic.

Meanwhile, the Liberty transaction, which reduced share count by 12%, could cause the company to pause share buybacks until 2027, which will likely weigh on shares, the analyst said.

The stock popped 8% on Monday on Berkshire’s disclosure. However, shares are still down more than 50% this year.

The last time Berkshire invested significantly in a major media company was in 2022, when the conglomerate bought a nonvoting stake in Paramount Global‘s class B shares. The investment soured quickly. Buffett revealed in May this year that he had exited the entire stock at a big loss.

Buffett said the unfruitful Paramount bet made him think more deeply about what people prioritize in their leisure time. He previously said the streaming industry has too many players seeking viewer dollars, causing a stiff price war.
