Warren Buffett shocked an arena full of his shareholders Saturday by announcing that he wants to retire at the end of the year.

Buffett said he will recommend to Berkshire Hathaway’s board that Greg Abel should become CEO at the end of the year.

“I think the time has arrived where Greg should become the chief executive officer of the company at year end,” Buffett said.

Abel has been Buffett’s designated successor for years, and he already manages all of Berkshire’s noninsurance businesses. But it was always assumed he wouldn’t take over until after Buffett’s death. Previously, the 94-year-old Buffett has always said he has no plans to retire.

Buffett announced the news at the end of a five-hour question and answer period and didn’t take any questions about it. He said the only board members who knew this was coming were his two children, Howard and Susie Buffett. Abel, who was sitting next to Buffett on stage, had no warning.

“I just want to say I couldn’t be more humbled and honored to be part of Berkshire as we go forward,” Abel said to shareholders about an hour later.

Many investors have said they believe Abel will do a good job running Berkshire, but it remains to be seen how good he will be at investing Berkshire’s cash. Buffett also endorsed him Saturday by pledging to keep his fortune invested in the company.

“I have no intention — zero — of selling one share of Berkshire Hathaway. I will give it away eventually,” Buffett said.

Thousands of investors in the Omaha arena gave Buffett a prolonged standing ovation after his announcement in recognition of his 60 years leading the company.

Abel expected to do well

In many respects, Abel has already been running much of the company for years. But he hasn’t been managing Berkshire’s insurance operations or deciding where to invest all of its cash. He will now take those tasks on, but Vice Chairman Ajit Jain will remain to help oversee the insurance companies.

Investment manager Omar Malik of Hosking Partners in London said before Buffett’s announcement that he wasn’t worried about Berkshire’s future under Abel.

“He’s had such a long time alongside Warren and a chance to know the businesses,” Malik said about Abel.

The question is will he allocate capital as dynamically as Warren? And the answer is no.

“But I think he’ll do a fine job with the support of the others,” Malik said.

Cole Smead of Smead Capital Management said he wasn’t surprised Buffett is stepping down after watching him Saturday because the 94-year-old wasn’t as sharp as in past years. At one point, he made a basic math mistake in one of his answers. At other points, he got off track while telling stories about Berkshire and his investing without answering the question he was asked.

Abel is well regarded by Berkshire’s managers and Buffett has praised his business acumen for years. But he will have a hard time matching Buffett’s legendary performance, and since he doesn’t control 30% of Berkshire’s stock like Buffett does, he won’t have as much leeway.

“I think the challenge he’s going to have is if anyone is going to give him Buffett or (former Vice Chairman Charlie) Munger’s pass card? Not a chance in God’s name,” Smead said. Buffett always enjoyed a devoted following among shareholders.

Buffett has said that Abel might even be a more hands-on manager than he is and get more out of Berkshire’s companies.

“I think we’ll get a more hands-on manager and that could be that a good thing,” Steven Check, who runs Check Capital Management, said beforehand. But he said Abel also knows that those managers enjoy the freedom to run their businesses and Abel isn’t going to do anything to turn them off.

Buffett earlier warned that Trump’s tariffs were harmful

Earlier, Buffett warned Saturday about the dire global consequences of President Donald Trump’s tariffs while telling the thousands of investors gathered at his annual meeting that “trade should not be a weapon” but “there’s no question that trade can be an act of war.”

Buffett said Trump’s trade policies have raised the risk of global instability by angering the rest of the world.

“It’s a big mistake in my view when you have 7.5 billion people who don’t like you very well, and you have 300 million who are crowing about how they have done,” Buffett said as he addressed the topic on everyone’s mind at the start of the Berkshire Hathaway shareholders meeting.

While Buffett said it is best for trade to be balanced between countries, he doesn’t think Trump is going about it the right way with his widespread tariffs. He said the world will be safer if more countries are prosperous.

“We should be looking to trade with the rest of the world. We should do what we do best and they should do what they do best,” he said.
