Berkshire won't be immune to Wall Street scrutiny without Warren Buffett at the helm

The legendary Warren Buffett has had a free pass on Wall Street for decades. Investors have put so much faith in him that they’ve basically ignored all the weird stuff Berkshire Hathaway does.

No earnings calls. No guidance. No easy-to-read reports. It’s all accepted… because it’s Warren. But that era ends on January 1st 2026, when Greg Abel becomes CEO. And the big question now is: will Wall Street cut Abel the same kind of slack?

He’s walking into a minefield. Berkshire is not your average company. Its financials are a labyrinth. Its assets are valued differently than how the market sees them. Its board includes family members. And it holds a huge chunk of cash without much explanation.

Berkshire’s Kraft Heinz and Occidental bets test investor patience

Take Kraft Heinz. Berkshire owns 27% of it, and as of March 31, they had it on their books at $13.5 billion. But the public stock price at the time valued the same stake at $9.9 billion. Today it’s dropped even more, to $9.4 billion. That’s a $4.1 billion difference. And that gap’s been there since early 2023.

Here’s the twist. Berkshire doesn’t mark that stake to market. Instead, they use something called the equity method. It lets them value the investment based on Kraft Heinz’s earnings, not the stock price. It’s totally legal. But it’s not what most companies do with public stocks. Buffett could’ve written down the value this year. He didn’t. He decided the drop was just “temporary.”

Now Kraft Heinz is trying to split itself up. That move might boost value if someone actually buys the separate parts. But investors aren’t impressed. After the Wall Street Journal reported the plan on July 11, the stock barely moved—up just 10%. Over the last year, it’s still down 12%. That’s not a market that’s excited.

Then there’s Occidental Petroleum. Berkshire owns 28% of that one. As of March 31, they valued it at $17.2 billion. But Wall Street only thought it was worth $13.1 billion. Fast forward to now, and it’s even lower; $11.5 billion. So between Kraft Heinz and Occidental, there’s a $9.8 billion gap between Berkshire’s internal valuations and what the market says.

That’s a lot of money to be off by, even for the Oracle of Omaha.

But no one on the trading floor dares say a word. At any other public company, this would be a red flag. Investors would be all over it. But because it’s Warren, people look the other way. Why? Because he’s spent decades preaching that mark-to-market gains and losses are “meaningless.” Investors believe him. For now.

But what happens when Abel is the one saying, “It’s temporary”? Will people still buy that? Or will they start asking real questions?

Abel inherits Berkshire’s weird structure, family board, and huge cash pile

Let’s talk about Berkshire’s overall setup. It’s not normal. It’s a messy mix of railroads, energy, insurance, retail, and more. It doesn’t report results like other companies. It doesn’t explain much. It doesn’t even hold quarterly calls. Some people love that. Others just stay quiet, because of Warren.

You’ve got subsidiaries pulling in billions that only get a sentence or two in the annual report. And then there’s the insurance side, where the numbers are mostly estimates and assumptions. That makes credibility a big deal. Investors have to trust the people at the top. And right now, that trust is tied to Warren. Not Abel.

The fact that Berkshire’s using internal valuations that are clearly higher than public stock prices makes it harder. Investors can check the real market prices any time. But they stay quiet because of who’s running the show. Once Abel takes over, that silence might end.

And let’s not forget the war chest. Berkshire is sitting on $348 billion in cash and Treasury bills. That’s 30% of its assets, just sitting there, and we all keep waiting to see what Warren will do with it, but so far, nothing. He hasn’t even been buying back stock, with buybacks at zero for the first half of 2025 and the first quarter of 2025. That’s a signal. He thinks the stock is too expensive.

All of this is what Abel’s walking into. He’s inheriting a company that’s been able to dodge scrutiny because of one man’s reputation. But that man won’t be CEO anymore. Sure, Warren will stay on as chairman. And sure, he’s endorsed Abel. But endorsements don’t transfer credibility. Trust has to be earned, especially when the numbers are this opaque.

Abel was CEO of Berkshire Hathaway Energy before, and he’s been vice chairman since 2018. He knows the company more than anyone else, sure, but he doesn’t have the same immunity. Warren could say the sky is green and investors would nod. Abel says it? They’re checking satellite images.
