Shares of kidney dialysis provider DaVita are up over 90% this year to $222, while the stock of satellite radio operator Sirius XM have risen almost 50% to $29. That followed a rough five-year period when DaVita was about flat while Sirius XM declined 65%.
Berkshire has large stakes in both companies. It owns about 29 million shares of DaVita worth more than $6 billion, a 45% stake. It also owns roughly 125 million shares of Sirius XM, a 37% interest, now valued at around $3.6 billion. These holdings are as of March 31.
The DaVita holding is likely Weschler’s largest Berkshire investment and Sirius XM is probably among his top five investments.
Weschler, who is about 65 years old, is believed to have been close to former Liberty Media CEO Greg Maffei. Berkshire’s large Sirius XM holding came about partly due to a combination of a Liberty-controlled company that held Sirius XM stock with Sirius XM in 2024. Berkshire had held a sizable stake in the Liberty entity.
Weschler, who joined Berkshire in 2012, has been associated with DaVita for more than a decade and he personally owns 2.2 million shares. He also holds almos t 790,000 shares of Sirius XM. These investments are as of late 2024, the most recent filing date that Barron’s is aware of.
