For sixty years, Warren Buffett’s name was Berkshire Hathaway’s most valuable, unlisted asset. On January 1, 2026, that asset changed hands, and for the first time in six decades, none of it went to a Buffett.

That fact alone should have been the headline. Instead, the world fixated on the familial succession as his eldest son Howard, was installed as chairman. In his letter to shareholders Warren Buffett described this appointment as the completion of a longer apprenticeship and essential to the company.

“Howard will guard its culture and vlaue – both worth more than anything on our balance sheet. Think of Howard as a policy the shareholders own and hope never to clain against. Howard cares deeply about Berkshire, as do all of our Directors. No company has been or will be more shareholder-minded than Berkshire.” Warren Buffett

But the more radical decision happened one door down, where Buffett handed the actual running of the company, capital allocation, acquisitions, the whole machine, to a quiet Canadian accountant named Greg Abel who isn’t related to him at all. Abel, has been working with Berkshire Hathway since 2000 initially through acquisition of Mid American Energy. The appointment of Abel as a successor was confirmed by Warren Buffett in 2021 and by May 2025 it was announced the Abel’s appointed as CEO would be finalised by the end of the year. Abel officially became CEO in March 2026.

The five year succession plan provided sufficient time to handle reactions both from the market and within the organisation. This in itself is one of the longest and most transparent approaches to succession, and unusual for global family businesses. Understanding why Warren split it that way is the real lesson in this succession story, and it sets up the second, quieter one still unfolding: what happens to the roughly $150 billion Buffett hasn’t handed to Abel, which rests instead with his daughter, Susie.

His three children, have roles affiliated with governance, protecting the culture, values and wealth distribution through philanthropy. Howard was announced as Non-executive Chairman of the Board in September 2026, he has served as a director in the company since 1993. His sister, Susie, joined the board in 2021 and is responsible for the dispersal of Warren’s wealth to philanthropic causes. The younger son, Peter has his own philanthropic orgganisation, but he shares trustee duties to distrubtion of funds.

The ‘Outsider’ Who Earned It

Greg Abel’s path to the top of American capitalism started with returning bottles for spare change in Edmonton, Alberta. He trained as an accountant, cut his teeth at PricewaterhouseCoopers, and joined a small geothermal energy company, CalEnergy, in 1992. When Berkshire acquired that company, by then renamed MidAmerican Energy, in 2000, Abel came with it. He spent the next two decades doing something almost nobody in modern business does anymore: staying in one place and quietly compounding trust. He became CEO of MidAmerican in 2008, took over as vice chairman of all of Berkshire’s non-insurance operations in 2018, and by 2021 Buffett had said the quiet part in an interview: if he dropped dead that night, Greg would be running Berkshire tomorrow.

That position is about meritocracy and performance over a quarter of a century, succession at it’s best when the right person is appointed because of their skills and results rather than lineage.

After Abel had spent years overseeing BNSF railroad, See’s Candies, Dairy Queen, and dozens of other businesses Buffett had acquired, with no public profile and, by most accounts, no interest in building one. Dairy Queen’s CEO put it simply: “He not only has high business acumen, but he has really high business instincts.” When Abel formally took the CEO title, he didn’t ease in. Within his first year he deployed $10 billion into Alphabet and paid $6.8 billion to acquire homebuilder Taylor Morrison. These decisive ‘Buffett-style’ bets that told the market the discipline hadn’t left the building, even though the last name on the door had changed.

Howard Buffett, despite 33 years on Berkshire’s board, was explicitly not given a say in capital allocation or acquisitions, Abel’s territory, therefore reducing the risk of conflict or a power struggle, as seen in other global family owned businesses. Buffett described Howard’s job as serving as a guardian of Berkshire’s culture and values, “worth more than anything on our balance sheet”, a check against any future leadership that might try to unwind what makes Berkshire unique.

Arguably the most interesting and important element is the roles allocated to all three siblings. Susie, Howard and Peter Buffett are the co-executors of their father’s will and joint trustees of the charitable trust receiving 99%-plus of his fortune. Unlike Abel’s job, there’s no earnings call to grade this one. Unlike Howard’s, there’s no single person accountable. It’s three siblings, required to act unanimously, deciding where more money moves each year than most countries spend on foreign aid.

Susie, the Sibling With the Longest Track Record

If Abel’s credibility was built running railroads and utility companies, Susie Buffett’s was built the same way, just further from the spotlight. She is Warren’s eldest child, born in Omaha in 1953, and for 25 years she has quietly run two foundations, the Sherwood Foundation, founded in 1999, and the Buffett Early Childhood Fund, founded in 2005, that have directed more than $1.3 billion to Nebraska-based causes in education, poverty alleviation, and social justice. Like Abel, she wasn’t handed a title; she built one, in relative obscurity, for decades before the scale of the assignment changed.

That track record matters more now than it ever has. In 2024, Buffett announced that his fortune, after his death, would go to a new foundation the three siblings must run jointly. The scale is genuinely daunting: the children will need to give away at least $15 billion a year, about 4% of all annual U.S. charitable giving, a burden Peter Buffett didn’t sugarcoat. “I did not want it,” he told CNBC . “I called him up and said, ‘I want to opt out.’ He said, ‘I don’t blame you.’”

Even Buffett has had to revise the plan mid-course. In March 2026, he acknowledged the original approach, waiting until his death to move the bulk of his fortune, wasn’t feasible given his own longevity, and accelerated lifetime gifts instead: roughly $500 million a year now flowing to the children’s foundations, Sherwood included, while he’s alive to see it deployed. It’s a rare public admission from a man famous for getting the math right the first time.

Two Kinds of Succession, One Discipline

Lay the two stories side by side and the same principle runs through both: Buffett separated competence from bloodline, then matched each to the job it was actually suited for. Abel earned the business through two decades of provable results. Susie earned her seat at the wealth-distribution table through 25 years of running foundations nobody made her run. Howard’s role, real, but bounded, is the one job where lineage itself is the qualification, because guarding culture requires a kind of institutional memory only a Buffett has.

What Family Offices Should Take From This

  • Hire the outsider when the job is running the business. Abel’s two-decade track record, not his name, is why capital allocation is safe. Families that insist on keeping operating control in-house regardless of readiness are optimizing for comfort over survival.
  • Separate the three successions. Who runs the enterprise, who protects its values, and who stewards the wealth are different competencies. Buffett assigned them to different people rather than loading one heir with all three.
  • Track records beat titles. Neither Abel’s CEO seat nor Susie’s role in the trust was conferred at the transition, both were earned over decades, in smaller decisions, long before the large ones arrived.
  • Plan for your own longevity risk. Buffett’s biggest miscalculation wasn’t in the business, it was underestimating how long he’d live relative to his original giving timeline. Build review points into succession and estate plans, not just a single triggering event.
  • Require unanimity as a structural safeguard. Forcing three heirs to agree before major wealth decisions move forward is a built-in check against any one of them drifting from the family’s stated values.

Berkshire’s stock didn’t blink when Abel took over, the clearest evidence the market believed the succession was real, not ceremonial. Whether the next generation of Buffett giving holds together with the same discipline is a quieter test, running now, with far less attention paid to it.
