What is Berkshire Hathaway without Warren Buffett in charge?

Tens of thousands of shareholders are hoping to find out when they descend on the legendary investor's hometown of Omaha next week.

They're making the pilgrimage to attend Berkshire's annual meeting, dubbed "Woodstock for Capitalists" because it attracts a huge crowd of like-minded investors for a weekend of learning, networking, and celebration.

But for the first time, Buffett won't be hosting the gathering. Instead, it will be Greg Abel, who took over as Berkshire's CEO at the start of this year, marking the end of the business icon's six-decade run.

Business Insider asked five Berkshire gurus what they'd like to hear from Abel next week. They shared questions about his management approach, plans for Berkshire's cash pile and stock portfolio, and even his personal life.

1. Trailing the index

Berkshire stock has declined 14% since Buffett's surprise retirement announcement on May 3 last year, while the S&P 500 has gained 26%.

David Kass, a finance professor at the University of Maryland and a longtime Berkshire blogger, said he would like to hear Abel's "explanation for Berkshire underperforming the S&P 500" by roughly 40 percentage points in under 12 months.

2. Money mountain

Berkshire held a record $373 billion of cash, Treasury bills, and other liquid assets at the end of December. That figure exceeds the market value of Chevron ($371 billion), Palantir ($365 billion), and Cisco ($355 billion).

Buffett, perhaps the world's foremost bargain hunter, struggled in recent years to deploy Berkshire's cash as stock valuations surged, acquisition prices soared, and even buybacks grew unattractive as Berkshire shares climbed.

Now Buffett has stepped aside, it's up to Abel to put that money to work.

"What are his plans to invest $373 billion in cash?" Kass asked.

Brett Gardner, an analyst and the author of "Buffett's Early Investments," raised the prospect that Berkshire might use its dry powder to purchase Buffett's roughly 14% stake in the business, a position worth $138 billion.

"Does Berkshire plan on buying Warren's stake in a negotiated transaction someday?" he asked.

3. Leadership revamp

Abel has made a few changes to Berkshire's top brass since taking over, most notably appointing NetJets CEO Adam Johnson as president.

Johnson and Katie Farmer, the CEO of Berkshire-owned BNSF Railway, will join Abel onstage for the second Q&A session.

Larry Cunningham, the author of several books about Berkshire and the director of the University of Delaware's Weinberg Center, told Business Insider he's looking forward to seeing Abel engage with the two subsidiary CEOs, "a new practice that I hope will add tremendous value to the meeting."

Gardner is also looking for indications of whether Abel intends to appoint other divisional leaders like Johnson. Under Buffett, subsidiary CEOs reported to Abel as the head of the non-insurance businesses, and Berkshire's insurance chief, Ajit Jain.

Chris Ballard, a managing director at Check Capital Management, said he was curious about Ted Weschler's expanded role at Berkshire. Abel touched on that in his first shareholder letter, following the departure of the other investment manager, Todd Combs.

Ballard said he was hoping Abel would share "some details on how often he sees Ted, how often he is in contact with Ted, and what sort of behind-the-scenes responsibilities Greg leans on Ted for."

4. Stocks and subsidiaries

In his first shareholder letter, Abel listed Berkshire's core stock holdings as Apple, American Express, Coca-Cola, and Moody's, leaving out two large positions — Bank of America and Chevron.

Ballard said he was "very interested" to hear Abel's thoughts on Berkshire's stocks and what kinds of businesses he'd consider adding to its core portfolio.

He also highlighted that almost nothing is known about Abel's investing experience.

"We don't know what Greg's past personal or professional investment performance looks like, and we are very interested in him describing some investment successes and failures, so we can get a sense for what we might expect going forward," Ballard said.

Paul Lountzis, a longtime Berkshire shareholder and the president of Lountzis Asset Management, said he was curious whether Abel would look to offload any subsidiaries. Buffett famously offered businesses a permanent home, which distinguished Berkshire from other buyers.

"Does he see Berkshire selling any businesses if they receive offers to buy some of the companies at attractive prices?" Lountzis asked.

5. Hands-on vs. hands-off

Buffett and his late business partner, Charlie Munger, structured Berkshire as a decentralized web of autonomous subsidiaries, which allowed them to focus on allocating capital inside and outside the company instead of running the businesses themselves.

Abel is a more hands-on manager and may demand more of Berkshire's businesses. He wrote in his letter that Pilot had ranked second in a study of travel centers' popularity, and he wouldn't be pleased until it takes the No. 1 spot.

He also noted that Berkshire first invested in Pilot in 2017 but was "contractually delayed" from managing it until 2023, and said, "that mistake will not happen again."

"His comments were uncompromising and could be taken as unwelcoming," Ballard said. "In the past, Buffett wanted Berkshire to be seen as a great home for a long-held family business, and he would remain hands off and allow the current owners to have autonomy. Abel's comments could deter such owners from approaching Berkshire in the future."

Ballard asked whether Abel would promise a permanent home to potential sellers, and whether he would allow the same level of autonomy as Buffett and Munger did or seek to optimize businesses after buying them.

6. Getting personal

Buffett is famous for his investing prowess, his philanthropy, his frugal lifestyle, his junk-food diet, and more. Very little is known about Abel by comparison.

"What does his typical day look like?" Kass asked. "What percentage of his time is spent on travel to Berkshire's companies? How many hours per day does he spend on investment research, such as reading 10-Ks?"

Ballard said he's eager to learn "more about Greg as a person, both personally and professionally." He suggested Abel could talk about his love of ice hockey, his formative life experiences, his philanthropy, and his friends in the business world.

"It'd be nice to hear stories about some interactions that have taken place with other professionals, who he admires — other than Buffett — and what inspires him," Ballard added. "What books does he like? What movies, etc.?"

7. Next generation

Berkshire has already seen its biggest shake-up in decades, and there could be more changes to come.

Gardner said he'd like to know who will succeed Jain, who turns 75 this summer, as insurance chief. Lountzis inquired about how Abel is working with his lieutenants to line up successors for when Jain and other executives step down.

Buffett has headlined Berkshire's big bash for decades. Shareholders are about to find out what it's like when he's not running the show.

• Arm announced its own AI chip, the AGI CPU, and is partnering with OpenAI and Meta.
• The new Arm AGI CPU aims to address energy efficiency and memory constraints in AI data centers.
• Despite strong growth prospects, Arm faces competition from established players like Nvidia and AMD.

Arm has long run its business as an architect behind the scenes, designing chips that power almost all the world's smartphone and making money off royalties from the chips it designs for customers.

Now, Arm is changing it up by announcing its own AI chip, the Arm AGI CPU.

Arm CEO Rene Haas said Tuesday at a company conference that this massive pivot wasn't just an internal strategy shift—it was a direct plea from the world's most powerful AI giants. The company name-dropped OpenAI and Meta as major partners for this chip.

"The biggest reason we're doing this is that our partners have asked for it," Haas said Tuesday.

With energy constraints and memory shortages, the AI boom has created a massive bottleneck in data centers. Faced with this demand, Arm stepped up with an AI chip that it says is more energy-efficient. Arm says it sees a $1.5 trillion market opportunity as it moves into AI chips for cloud, edge, and physical AI.

Arm stock was up by more than 18% on Wednesday. Mizuho analysts wrote that they see "strong growth opportunities" for Arm in AI infrastructure and the automotive industry. Bank of America research analyst Vivek Arya wrote in a note to investors that the company's outlook could be "too ambitious."

Meta and OpenAI partner with Arm

Meta has been building out data centers at a massive scale to power its apps and its latest superintelligence ventures. Santosh Janardhan, head of infrastructure at Meta, said Tuesday onstage that its coming "Hyperion" cluster could draw 5 gigawatts of power, enough to power 50 towns the size of Palo Alto.

"If we met the performance, we couldn't get the power. If we got the power, we wouldn't get the performance," Janardhan said.

This sparked an engineering project within Meta, where engineers were "working 'round the clock" to port its systems to Arm in three months, said Paul Saab, a Meta engineer.

"I didn't even ask my boss here for permission to buy these machines or even start the project," Saab said onstage.

While Saab says he saw major performance benefits, at the time, there wasn't an Arm chip available to buy.

OpenAI faced a similar problem. Its compute demand has grown massively as it trains and runs its ChatGPT models, its AI coding tool Codex, and more.

"That is one of the most common things I hear inside OpenAI. I need more compute," Kevin Weil, vice president of OpenAI for science, said onstage, adding that it needed chips that were energy-efficient.

Arm said it expects this chip to generate $15 billion in revenue by fiscal 2031.

The chip market is 'getting very crowded'

Arm faces the risk that the CPU market is "getting very crowded," Arya wrote in his analyst note. Other competitors, such as AMD, Nvidia, and Intel, have more CPU products and more established customers. Notably, both Meta and OpenAI also work with AMD and Nvidia, which could leave "limited" opportunity for Arm's new CPU, Arya wrote.

"Moreover, the bigger AI grows, the more pressure ARM's smartphone/consumer markets would have from limited memory supplies," Arya wrote.

That said, the increasing demand has led many customers to turn to chip companies beyond Nvidia for their computing needs. Both Meta and OpenAI also work with Broadcom to build AI chips.

The rise of AI agents has also led to greater demand for inference, or how AI models draw conclusions and make predictions. While Nvidia's core AI chips, the GPUs, dominate AI training, CPUs like Arm's AGI CPU can also help with inference. Nvidia also recently made moves into this market.

• If the AI boom ends up a bust, it won't be nearly as brutal as the dot-com crash, Igor Pejic says.
• The "Tech Money" author said Big Tech's self-reliance, varied businesses, and deep pockets help.
• However, he said the rise of index funds means a market slump would have widespread impacts.

If the AI boom collapses, it won't be as catastrophic as the dot-com crash — but the shockwave will be felt far and wide, Igor Pejic says.

The banker and author of a new guide for tech investors titled "Tech Money" told Business Insider this week that Big Tech's unprecedented dominance will limit the magnitude of any market decline.

Pejic underscored the greater "stickiness" of companies like Alphabet and Microsoft compared to the leading companies of the past, such as Exxon Mobil, General Motors, and IBM.

Big Tech companies have remained dominant for decades partly because of their platform models, which give them "almost limitless pricing power" and make them "almost impossible to dislodge," he said.

In other words, they've become powerfully entrenched by attracting so many users, app developers, hardware suppliers, advertisers, and other parties to their ecosystems over time. Now they can easily hike their fees, and new market entrants struggle to capture any market share from them.

Pejic also pointed out that Apple, Meta, and their peers have successfully navigated multiple technological shifts, such as moving from desktop computers to mobile devices and from on-premises IT equipment to cloud hosting.

Big Tech companies also throw off gobs of cash, enabling them to place several big bets at once, and fund their investments instead of relying on costly external financing. Pejic described that as a "moat" against rivals, especially in an AI race characterized by "tremendous infrastructure costs."

Shades of the past

Pejic drew several parallels between the AI boom and the dot-com bubble. The similarities include a game-changing technology, partnerships and financing deals between key players, the buildout of network infrastructure, and "extreme" valuations, he said.

Yet Pejic said an AI crash would "not be as devastating as the dot-com bubble when it burst."

Any market sell-off will be briefer and less severe because today's tech giants have highly profitable core businesses, he said, meaning their stock prices won't collapse completely if their AI bets flop.

They're also less likely to suffer a cash crunch or trigger a financial crisis given their limited reliance on bank funding, and investors have been more discerning about which AI stocks they buy versus rushing to own any business with ".com" in its name, he said.

Pejic did raise some concerns, including the fact that so many companies are spending huge amounts to build the best AI model possible, but the market can probably only support a few of them in the end.

He also flagged the immense amount of investor cash riding on a handful of tech stocks, given the rise of index funds that own indexes such as the S&P 500, which is weighted by market capitalization and thus intensely concentrated in the Magnificent Seven.

"It's very difficult to find a place to hide if this really goes down," Pejic said. "If you're keeping your money in the stock market and AI goes down, it will affect everything."

He noted that risk will only become greater as AI giants such as OpenAI, xAI, and Anthropic go public and join the index, increasing everyday investors' exposure to AI.

Pejic said owning Big Tech stocks was "perhaps the safest way" to profit from AI, given their self-reliance, vast resources, and diversified businesses, which should limit their downside and insulate them from industry shocks such as the emergence of DeepSeek.

For example, he praised Apple's approach of refraining from spending hundreds of billions on microchips and data centers, in favor of seeing how the AI race plays out, and partnering with peers or buying in capabilities to harness the tech.

Apple might not be the "most exciting company," but for investors, owning it is a "clever and quite safe strategy without burning too much cash," he said.
