Buffett Splits His Job in Two at 96: Greg Abel Gets the Capital, Howard Buffett Gets the Culture

Warren Buffett's exit as Berkshire Hathaway chairman came with one last lesson on succession: the person who allocates the capital and the person who guards the culture don't have to be the same. Any CFO who wants the CEO job should study that split closely.

On September 18, Buffett stepped down as chairman of Berkshire at 96, after more than six decades in the role. His son Howard G. Buffett takes the chair, Greg Abel stays on as CEO (he took over in January), and Buffett remains on the board as chairman emeritus. In his letter to shareholders, he summed up the whole arrangement in one line: "Greg runs the company; Howard will guard its culture and values." I love how blunt that is.

What caught my attention is that Buffett refused to pretend one person could inherit everything he did. Most succession plans assume the next leader takes the P&L, the capital decisions and the soul of the company in one package. Buffett looked at his own job, saw two jobs, and handed them to two people. He even described Howard as an insurance policy the shareholders own and hope never to claim against, which tells you the chair here exists to protect, not to operate.

Abel, meanwhile, is using capital allocation to define his tenure, and fast. Berkshire bought $39.4 billion of stocks in the first half of 2026, against $7.1 billion in the same period a year earlier, and roughly $10 billion of Alphabet purchases made it Berkshire's third-largest holding. As Fortune's Sheryl Estrada frames it, the real test isn't whether Abel can copy Buffett. It's whether he can keep Berkshire's discipline while making calls Buffett might never have made himself.

This is where I think CFOs should pay attention. Capital allocation is the half of the job we're already trained for, and Abel shows it's the fastest way for a new leader to put their stamp on a company. But the Berkshire model also says boards will look for someone to carry the culture, and that's exactly where finance leaders get passed over. Too many CFOs are seen as stewards of the numbers, not of the people and the values behind them.

So here's the question I'd ask myself this week. If your CEO left tomorrow, which half would the board hand you: the capital, the culture, or both? If the honest answer is only the capital, that's your work for the next twelve months. Lead something outside finance, own a decision that is about values rather than returns, and be visible in how the company treats its people and customers. And while you're at it, look at your own team the same way, because the person who guards your numbers and the person who guards how your team works may not be the same person either.
