Billionaire Warren Buffett on Saturday gave a clue on who might succeed him to run his Berkshire Hathaway empire, but did not completely reveal his hand.
The world's third-richest man also said at his company's annual shareholder meeting that its recent investment in Amazon was not a shift in strategy to focus on Silicon Valley firms, which have largely remained missing from Berkshire's voluminous portfolio.
Buffett, 88, was pressed by questions - each greeted with a torrent of applause - about who would succeed him.
Without answering directly, Buffett said Gregory Able, 57, and Ajit Jain, 67 - both promoted last year to the board of directors - would in the near future join him and long-time business partner Charlie Munger, 95, on the stage to answer shareholder questions.
"You could not have two better operating managers than Greg and Ajit. It's just fantastic what they've accomplished," said Buffett, who is known as the "Oracle of Omaha."
For decades, Buffett and Munger have been the two stars of Berkshire Hathaway, but on Saturday, Jain answered a shareholder question, though he did so from the floor.
Abel joined the company in 1992 in the energy division, and for more than a year has overseen all non-insurance activities, while Jain came on board in 1986 in the insurance division, which he currently leads.
But who will prevail, or could they jointly take the helm?
"One of the reasons we have trouble with these questions is because Berkshire is so very peculiar. We have a different, kind of unbureaucratic way of making decisions," said Munger.
"But I don't want to be like everybody else because this has worked better. So I think you're going to have to endure us," he said.
Buffett's departure is likely to open a new era at the company, especially with shares of Berkshire considered to be 10 to 15 percent above their real value thanks to the billionaire's presence at the helm.
Some analysts say a Buffett-less Berkshire Hathaway could be a candidate for being broken up into multiple companies.
Investing in tech
On Saturday, Buffett and Munger also faced an onslaught of questions about strategy for investing in technology companies after Berkshire revealed a stake in Amazon.
Buffett said Amazon chief Jeff Bezos has pulled off "close to a miracle" by transforming an online bookseller into the e-commerce giant it is today.
Munger also acknowledged that he and Buffett felt "ashamed" for missing the boat on Google.
"We just sat there sucking our thumbs," he said. "We screwed up."
But there's no indication of a strategy shift at Berkshire to invest more heavily in tech, aside from its new stake in Amazon and a $40-billion stake in Apple.
On Saturday, Berkshire Hathaway announced a net profit of $21.66 billion - a result that does not take into account expected losses from its stake in Kraft Heinz, which has recently depreciated assets valued in the billions of dollars.
Berkshire Hathaway has holdings in companies such as American Express, JPMorgan Chase and Goldman Sachs, and is active in sectors like insurance (Geico), rail (BNSF) and energy (PacifiCorp).
The Berkshire Hathaway shareholder meeting, which draws tens of thousands to the small city of Omaha in the American heartland, has been dubbed "Woodstock for Capitalists."
Unlike other annual meetings, the goal here is not to release company results but to hear Buffett identify companies that he might invest in, or from which he might withdraw his money.
Some 20,000 people secured a coveted pass to hear Buffett speak in person, after lining up from 5:00 am, with thousands more left to soak up the atmosphere from outside the theater.
Buffett kicked off the day by touring the souvenir stands at CHI Health Center and mingling with the crowd of attendees, made up of leading executives, investors and billionaires from around the world.
This year, many Chinese delegations made the trip.
He later made a surprise appearance at a sideline event organized by a group of women financial professionals aiming to end the gender imbalance in investing.
"It's long overdue," Buffet said of the goal.
Buffett, who is worth almost $90 billion, still lives in a relatively modest house about 10 minutes outside downtown Omaha that he bought in 1958.
Who will succeed billionaire Warren Buffett?
As the annual shareholder meeting of Berkshire Hathaway gets underway on Saturday, a key question hangs over the gathering: who will take the reins of the empire built by 88-year-old billionaire Warren Buffett?
"Warren Buffett is irreplaceable," said Macrae Sykes, a research analysts at Gabelli & Company.
But Meyer Shields, managing director at the investment firm Keefe, Bruyette & Woods, was less concerned.
"Berkshire Hathaway can certainly survive without Warren Buffett," he said. After all the conglomerate is made up of "mostly solid businesses that are only minimally impacted by their ownership."
Investors are not expecting major upheaval, since Buffett has taken steps in recent years to carefully prepare for a leadership change, although he has not made the plan public.
Among four likely candidates, there are two clear frontrunners: Gregory Abel, 57, and Ajit Jain, 67, who were both promoted last year to the board of directors and who are both known quantities who have been with Buffett for decades.
Abel joined the company in 1992 in the energy division, and for more than a year has overseen all non-insurance activities.
Jain came on board in 1986 in the insurance division, which he currently leads.
Also potentially in the running are Todd Combs, 48, and Ted Weschler, 56, chosen by Buffett and his long-time business partner, Charles Munger, 95, to handle the group's investments.
"That's never been officially disclosed, but I suspect it will be either Greg Abel or Ajit Jain... and probably the former, given his solid and growing exposure to Berkshire's non-insurance businesses," Shields said.
Sykes agreed, noting that Jain "really likes to focus on insurance businesses and... seems less interested in the spotlight."
It is always possible a dark horse candidate could emerge from the company's board, which includes fellow billionaire and Microsoft founder Bill Gates.
One is Tracy Britt Cool, 35, a Harvard graduate and Buffett's right-hand woman for the past 10 years.
Regardless of who the successor will be, Shields said markets should at first "respond very negatively" to Buffett's absence, in part due to his unique status.
But it is also partly because Berkshire's "exceedingly weak" disclosures "have forced investors to rely more on Mr Buffett's carefully-managed public persona than on the companies' individual or aggregated earnings potential," Shield said.
Gregori Volokhine, portfolio manager at Meeschaert Financial Services, said Buffett's presence added 10 to 15 percent to the company's share price, and without him, that premium would "disappear."
