- After the September 2024 deal that created today's Sirius XM, Berkshire bought its stock in four rounds of purchases. The last, in August 2025, cost about $21.16 a share.
- Then it reported no purchases for almost 15 months, while the stock closed as low as $19.92 and later as high as $32.59.
- When it started again on Oct. 30, it paid about $29.10 a share, a higher average than in any earlier round. The $26.9 million is under 1% of its stake's Nov. 3 value.
- Its slice can grow without buying: when a company buys back its own shares, every remaining owner holds more. Sirius's finance chief said on Oct. 29 he sees potential to speed up buybacks in 2027.
- Next: Sirius pays a $0.27 dividend on Nov. 23 to shareholders of record on Nov. 6. On the 109.7 million shares Berkshire's insurer GEICO holds, that is about $29.6 million, by KeyVex's math.

Most of the stake, 109.7 million shares, is held by Berkshire's insurer GEICO. The other 16 million are held by pension plans of Berkshire companies. The filing counts those in its total, but Berkshire, Buffett and the plans disclaim beneficial ownership of them: under securities law, none of them claims to be the shares' beneficial owner.Form 4
What Sirius said on Oct. 29
Sirius reported third-quarter results before the market opened on Oct. 29. Net income rose 7% to $317 million, while revenue slipped to $2.15 billion. It added a net 5,000 self-pay subscribers, who pay for their own plans.8-K
It also raised its 2026 targets for revenue, free cash flow and adjusted EBITDA, a measure of operating profit, by $25 million each, the second quarter in a row it raised them.8-K The stock closed up 4.9% that day.Chart data
On the results call, chief executive Jennifer Witz said the company anticipates "a more challenging fourth quarter for self-pay subscriber trends." Self-pay net additions for the year are now expected to be about flat with 2025, she said, according to transcripts published by The Motley Fool and Investing.com.TranscriptTranscript
Steven Cahall, a Wells Fargo analyst, said on the call: "we are backing into Sirius XM self-pay gross adds maybe down around double digit for the last couple of quarters." Gross adds are new subscribers signing up. He was leaving out Companion plans, which extend a subscription to more devices and household members, and noted that churn, the rate of cancellations, was improving.TranscriptTranscript Companion plans added 107,000 self-pay net additions in the quarter, Sirius said.8-K
Witz did not confirm or dispute his estimate. She said the company has been developing new opportunities "outside of this traditional in-car funnel," the transcripts show.TranscriptTranscript
How Berkshire's share can grow without buying
Sirius also buys back its own stock. It spent $33 million on buybacks in the third quarter and had $963 million left under its authorization at Sept. 30.8-K10-Q Each share it retires raises the percentage every remaining owner holds, Berkshire's included.
Explaining the company's buyback plans, chief financial officer Zac Coughlin said on the call that management believes its share price "represents a compelling investment opportunity." The company sees "potential to meaningfully accelerate share repurchases in 2027," he said, according to the transcripts.TranscriptTranscript
Sirius also pays a quarterly dividend of $0.27 a share. On the 109.7 million shares held by GEICO, the one due on Nov. 23 comes to about $29.6 million, by KeyVex's math.10-QForm 4

How we got these numbers
- Prices are end-of-day closes as traded, not adjusted for dividends. Closes before Sept. 10, 2024, are adjusted for the share exchange in the transactions that created today's Sirius XM Holdings, which closed on Sept. 9, 2024. Daily moves are close to close. The S&P 500 and Nasdaq 100 lines follow SPY and QQQ, also as traded, rebased to Sirius's close at the start of the range shown. The Filings switch shows the filing markers from KeyVex's Sirius page, a selection of filings: not every filing, and not only those tied to this story.
- Berkshire's purchases, prices and holdings come from the transaction rows of its seven Form 4s for Sirius XM since October 2024 (26 purchases in all). A round groups purchases with no break longer than two weeks. Each round's average price is the share-weighted average of the prices on those rows, and dollar amounts are shares times those prices. The filings report each day's price as a weighted average of several trades.
- The holding figures include the 15,984,890 shares held by pension plans of Berkshire subsidiaries, as the Form 4 reports them, although Berkshire, Buffett and the plans disclaim beneficial ownership of those shares. The 37% stake uses the 336,486,715 Sirius shares outstanding on Oct. 27, 2026, from Sirius's 10-Q; the $3.9 billion value uses the Nov. 3 close.
- "No purchases" from Aug. 5, 2025, to Oct. 29, 2026, rests on two checks: the holding Berkshire reported before its Oct. 30 purchase equals its holding after Aug. 4, 2025, and Sirius's list of filings on EDGAR shows no Berkshire Form 4 in between.
