Warren Buffett’s Berkshire Hathaway Succession: Greg Abel and 7 Lessons for Leaders
Imagine the final moments of Warren Buffett’s May 3, 2025, 60th annual meeting. First of all, how many people have held 60 annual meetings for their company? Very few. So here we had the Oracle of Omaha, 94 years old, standing before about 40,000 shareholders and guests, and almost no one knew about the shocking news he was about to deliver.
All of a sudden, Buffett says, “I think the time has arrived where Greg should become the Chief Executive office of the company at year end,” and hands over the reins of an over $1 trillion organization so many admire to a man most people have never heard of.
Why did Buffett wait so long to announce his successor, and what makes Greg Abel the best choice?
And what if you could build a company with the discipline of Warren Buffett, the vision of Berkshire Hathaway, and the adaptability to survive any market (so far at least)?
Whether you’re a management consultant, a member of a strategy team, or an executive seeking partner-level impact, this story is a good example of how leadership transitions at the very top are made and how they impact strategy, culture, and the future of a major organization.
As we dissect Berkshire Hathaway’s most consequential leadership change of the century, pay attention to what you can apply to your own journey: the operational rigor, board-level executive presence, and agility that leaders like Greg Abel and Warren Buffett exemplify to all of us.
And they are not perfect, of course. Buffett's company owns a lot of insurance companies, and we all know how insurance companies treat their customers in America. They extract from clients what is, in economic terms, called rent. Meaning they extract from clients a lot more than what is fair under contract. For example, you often have to allocate many hours every week calling them and faxing them just for them to eventually reply to you to try to push one step forward, which is what they are required to do as part of the contract.
So I had to say it as a side note, for us not to think that Buffet or Greg or anyone is a perfect role model. But even if someone is not a perfect role model, we can learn from them.
So, back to our story.
THE MOMENT THAT CHANGED EVERYTHING
From what I can observe, Buffett’s choice was made carefully and over a multi-year period. He did give some hints in shareholder letters and interviews about who would be taking over, but many people were very surprised that it ultimately was Greg Abel.
Greg Abel is an interesting character. Not the investor's "celebrity. He is someone with operator's discipline. Reminds me of Steve Jobs' selection of his successor.
Once the announcement was made, questions poured in. Could Greg Abel fill Buffett's shoes? What does it all mean for Berkshire's future? How will shareholders be impacted?
HUMBLE BEGINNINGS TO BIG LEAPS
Greg Abel was born in 1962, far from Wall Street. He grew up in Edmonton, Alberta (Canada). As many of you know, I am Canadian and American, so it's very good to have someone from your homeland succeed.
His teenage years had similarities to Buffett's: they both were business-minded early in their lives. Greg was delivering flyers, collecting bottles, and even worked as a forestry laborer.
He played ice hockey, which is ordinary for a man growing up in Canada, especially in Alberta. People say he learned “you are more successful if you play as a team than as an individual” from ice hockey.
He got a scholarship from his fire extinguisher-filling job and earned an accounting degree from the University of Alberta in 1984. I was 3 years old at the time, and many of you probably were even younger, so imagine the impact we can still make (in case you are comparing your accomplishments to Greg's).
Anyway, Greg started as a chartered accountant at PwC in Edmonton. I actually also worked for PwC, Canada, which was a breath of fresh air after my stint in banking. It was an interesting learning experience to manage a portfolio of over $1 billion, but the toxic culture erodes you from the inside at record speed.
After Edmonton, he moved to San Francisco. Then he joined, before joining a little-known power producer called CalEnergy in 1992.
ASCENT AT BERKSHIRE
At CalEnergy, Greg Abel’s work ethic is what sets him apart and makes him visible. This is what we always mention, over the last 15 years of running StrategyTraining.com and FIRMSconsulting.com. And what you can see clearly from my career. You can outwork anybody. Don’t underestimate how far you can go if you just do the work, skill up consistently, seek higher levels of responsibility and compensation, invest in yourself with more diligence than you do in your retirement investments, and treat every job as if you are the owner.
Anyway, back to our story. Greg Abel quickly rose through the ranks. He led transformative deals, including acquiring MidAmerican Energy. MidAmerican Energy was noticed by Berkshire Hathaway in 2000, and they took control. Greg became an important asset for Berkshire Hathaway.
He was promoted to CEO of MidAmerican (renamed Berkshire Hathaway Energy) in 2008. Greg Abel managed utilities and renewable assets, making acquisitions like NV Energy ($5.6B in 2013) and turning Berkshire Hathaway Energy into a renewable energy leader. Under his leadership, the company grew to serve over 11 million customers and made over 10% of Berkshire’s total earnings.
Greg Abel is known for his detail-oriented approach as a leader, versus Buffett's famous hands-off delegation approach. In fact, Greg Abel is described as someone who “does more in every hour of every day than any person I’ve ever met”. He is known for asking probing questions. I am not surprised, though. Given his background in accounting, he has a very good understanding of what business needs to succeed and what will lead to failure. In fact, when I lived in South Africa, I noticed the highest chance to become very senior there, all the way up to CEO, is to have an accounting degree as your foundational training.
THE SUCCESSION GAMBLE
Most conglomerates struggle with succession. Buffett spent years grooming Greg Abel. In his last shareholder letter, Buffet wrote: “Abel has vividly shown his ability to act at such times as did Charlie”. This is, of course, drawing parallels to the late Charlie Munger.
Greg Abel is now responsible for the over $1 trillion behemoth. Shares include Apple, American Express, BNSF Railroad, and Geico. And yes, $350 billion in cash. As a result, Greg's decisions on capital allocation, risk, and innovation will shape not just Berkshire but the future of American business as a whole.
THE LEADERSHIP STYLE: HANDS-ON, HUMBLE, HIGH EXPECTATIONS
People say that Greg Abel’s leadership is “substance over style.” Colleagues describe him as intensely hard-working, humble, and very sharp. They say he is focused on team wins and avoids the spotlight.
Buffett himself mentioned (I guess joked) that Greg Abel’s more hands-on style “is working way better for Berkshire's 60-plus subsidiaries. I didn’t want to work as hard as he works”. Late Charlie Munger called Greg Abel “sensational in business, both a thinker and a doer … exceptional at getting things done smoothly through others.”
UNCERTAIN FUTURE, HIGH EXPECTATIONS
But let's remember, Greg Abel faces a tough challenge. With a lot of power comes a lot of responsibility. Will he be bold with the conglomerate’s massive cash reserves? Will he make decisions Buffett avoided? And he has to make good decisions while everyone is watching.
Buffett told shareholders, “I would leave the capital allocation to Greg, and he understands businesses extremely well”. The torch has passed, but who knows how things will unfold.
I will wrap this up with 7 lessons from Berkshire Hathaway’s succession.
1. Start Planning Early
Buffett didn’t wait until the last minute to choose who would lead after him. He started thinking and planning many years ahead. This helps everyone feel ready and not surprised when change comes.
2. Hard Work Matters More Than Being Famous
Greg Abel wasn’t a well-known star. From what we know about him, he worked really hard, learned the business, and cared about his team. That’s why Buffett trusted him. Doing your best every day is what counts most. That is something I have done throughout my career, and it really does pay off.
For example, when I immigrated the first time, and after 8 months of applying for every job I could qualify for, I finally got one, I would be the first to come and the last to leave. I would do everything I possibly could to move things forward for the business, and that was noticed, and I got promoted very fast.
I approached my undergraduate studies the same way, and despite having to translate almost every word in my first economics book, I graduated with summa cum laude, with straight As, and was the top 3 student for my economics class nationwide for that university.
I followed the same approach when I joined consulting and, as a result, got promoted 3 times in 2 years.
Then, I followed the same approach during MBA and graduated on the Dean's list, even though at the beginning it looked like that would not be possible since everyone in class was a top student with very high GMAT scores, and most people were native English speakers.
After MBA I followed the same approach in banking and got promoted to director, managing a portfolio of over 1 billion dollars in just 6 months.
And, of course, I am using the same approach in building StrategyTraining.com and FIRMSconsulting.com. And, of course, I would never have had a chance to work with Michael on building StrategyTraining.com without all the steps above.
So, treating each job like you are an owner, but not settling for what you achieved, is a phenomenal approach to basically guarantee a successful career.
3. Always Share and Explain Your Plan
Buffett wrote long letters to explain how the company works. He made sure everyone understood what he wanted and why. When leaders are open and clear, people trust them more.
4. Teaching Others Is Important
Buffett didn't just do everything himself; he taught others how to run the company. Greg Abel learned directly from Buffett. Great leaders teach and let their team grow. When I see our clients making sure their team is trained using FIRMSconsulting resources versus hoarding it only for themselves, this is when I know this leader will go far.
5. Keep Things Simple
Buffett kept the company simple. Even as the business got much bigger, he made sure the rules stayed simple to follow. Not easy but simple. Simple plans work best for most teams.
6. Respect What Worked, But Be Ready to Change
Greg Abel will probably keep doing the things that made Berkshire great, but he’ll likely also make changes when needed. It's important to balance old habits with new ideas, especially when the world changes so fast. Now, with AI and other technological changes, this is the only way to even stay in business.
7. Teamwork Is Stronger Than Going It Alone
Buffett and Greg Abel believe in working with others. Just think about the Charlie and Warren duo. Their teams make better decisions together, and people help each other. Leading with teamwork helps companies do well, even when things get tough. StrategyTraining.com and FIRMSconsulting.com would never be able to do what we are able to do without our amazing team.
Everyone can learn from how Warren Buffett and Greg Abel handled this change. Plan ahead, work hard, be honest and clear, help others learn, keep things simple, respect the past but keep learning and be ready to adapt, and always act as a team. That’s what helps leaders, and their companies, succeed for a long, long time.
For every consultant, strategy head, and executive, Greg Abel’s next moves will offer living case studies in succession and adaptability. How will a “hands-on operator” shape capital allocation, innovation, and leadership at one of the world’s great empires? We have already seen it play out with Tim Cook. And now will have front row seats to see how it will play out with Warren Buffett.
