Greg Abel: An In-Depth Analysis for Serious Investors
Greg Abel became the public face of Berkshire Hathaway's succession when Warren Buffett confirmed in 2021 that Abel would take over as CEO. As of April 2026, Abel runs all non-insurance operations at Berkshire, which includes businesses generating over $120 billion in annual revenue across energy, railroads, manufacturing, retail, and services. For investors holding BRK.B at a price-to-book of 1.5, understanding Greg Abel's track record and philosophy is now as important as understanding Buffett's.
This analysis covers Abel's professional history, his record at Berkshire Hathaway Energy, his approach to capital allocation, and the specific data points that matter for long-term Berkshire shareholders.
Key Takeaways
- Greg Abel has run Berkshire Hathaway's non-insurance operations since 2018 and was publicly confirmed as Buffett's successor in May 2021.
- At Berkshire Hathaway Energy (BHE), Abel oversaw growth from a $2 billion acquisition in 2000 to a business generating over $25 billion in annual revenue by 2024.
- Abel is a capital allocator, not an operator who manages day-to-day decisions. He evaluates acquisitions, oversees subsidiary CEOs, and decides where retained earnings go.
- His style mirrors Buffett's in three ways: long holding periods, minimal headquarters interference in subsidiaries, and a preference for businesses with durable competitive advantages.
- The key uncertainty for Berkshire shareholders is whether Abel can replicate Buffett's ability to source large, off-market acquisitions at favorable prices.
- BRK.B trades at a price-to-book of approximately 1.5, which is within historical fair value range for the business given its cash generation and equity portfolio.
Who Greg Abel Is
Greg Abel was born in 1962 in Edmonton, Alberta. He studied accounting at the University of Alberta and spent the early part of his career at PricewaterhouseCoopers before moving into energy. He joined CalEnergy, a geothermal energy company, in 1992 and became president of its successor, MidAmerican Energy, in 1998. Berkshire Hathaway acquired a controlling stake in MidAmerican in 2000, and Abel became CEO of the renamed Berkshire Hathaway Energy in 2008.
Abel is not a public personality in the Buffett mold. He does not write annual letter essays or make frequent television appearances. His name appears on regulatory filings, in acquisition announcements, and in the Berkshire Hathaway annual report sections covering the energy business. Investors who have watched him at annual meetings describe a methodical, technically precise communicator who responds to operational questions with specific numbers.
His Record at Berkshire Hathaway Energy
Berkshire Hathaway Energy (BHE) is the most detailed window into how Abel manages capital. Buffett paid $2 billion for the original MidAmerican stake in 2000. By 2024, BHE generated roughly $25 billion in annual revenue and owned regulated utility operations across Iowa, Nevada, Utah, Wyoming, and the United Kingdom, along with one of the largest renewable energy portfolios among U.S. utilities.
| BHE Metric | 2005 | 2015 | 2024 |
|---|---|---|---|
| Revenue | $7.2B | $18.2B | $25.1B |
| Net Earnings | $0.54B | $2.1B | $2.6B |
| Renewable Capacity (MW) | ~500 | ~7,000 | ~31,000 |
| Employees | ~19,000 | ~27,000 | ~24,000 |
The renewable energy build-out is significant. BHE invested over $35 billion in wind and solar capacity from 2010 to 2024, using internally generated cash flows and regulated utility returns to fund the expansion without external equity issuance. This is textbook Abel capital allocation: reinvest where regulated returns are visible and long-duration, avoid financing that dilutes existing owners.
The 2023 Iowa wildfire liability at PacifiCorp, a BHE subsidiary, introduced a material uncertainty. PacifiCorp faces roughly $4 billion in wildfire-related claims across Oregon and California. BHE reported a charge of $2.7 billion in 2023 to cover its estimate of those liabilities. This is the most significant setback in Abel's BHE tenure and the primary reason Berkshire's earnings from BHE were suppressed in 2023 and 2024.
How Abel Allocates Capital
Abel's capital allocation philosophy at the Berkshire level runs through four channels: acquisition of whole businesses, additions to existing subsidiaries, common stock investments through the equity portfolio, and share repurchases when BRK trades below intrinsic value.
On acquisitions, Berkshire bought Alleghany Corporation for $11.6 billion in 2022, which was the largest Berkshire acquisition since Precision Castparts in 2016. Abel's fingerprints are on the sourcing and due diligence. Alleghany is a reinsurance holding company, which fits the Berkshire model of capital-light businesses generating float.
On repurchases, Berkshire spent $9.2 billion buying back BRK shares in 2021, $7.9 billion in 2022, and slowed to $2.2 billion in 2023 and $2.9 billion in 2024 as the share price climbed above Buffett's comfort level near 1.2x book value.
The cash position is the most-watched number on Abel's watch. Berkshire held $334 billion in cash and Treasury bills at the end of 2024, a record level that reflects both the absence of large acquisition opportunities at attractive prices and a higher opportunity cost calculation as short-term rates rose above 5%.
Abel vs. Buffett: The Differences That Matter for Investors
The comparison is inevitable. The honest answer is that no one has replicated Buffett's sourcing network, personal relationships with CEOs, and 70-year track record of capital allocation. Abel does not need to.
| Characteristic | Warren Buffett | Greg Abel |
|---|---|---|
| Deal sourcing | Mostly inbound, personal network | Mix of inbound and process-driven |
| Public persona | Prolific communicator | Methodical, low-profile |
| Investment style | Public equities and whole businesses | Primarily whole businesses |
| Regulatory background | Insurance/finance | Energy regulation |
| Age in 2026 | 95 | 63 |
The biggest structural difference is that Buffett personally runs the equity portfolio, allocating capital to individual stocks like Apple (AAPL), which carries a P/E near 28.3 and a ROIC of 45.1%. Abel has not been the decision-maker on public equity positions. When Buffett steps back, the question is whether Abel delegates equity portfolio management to Todd Combs and Ted Weschler or centralizes it himself.
Both Combs and Weschler have managed sub-portfolios at Berkshire since 2012 and 2011 respectively. Their combined allocation was around $30-40 billion as of 2024. Scaling that to the full equity portfolio is operationally feasible but represents a meaningful shift in how Berkshire operates.
What BRK.B's Valuation Looks Like Under Abel
Berkshire Hathaway B-shares trade at approximately 1.5x book value as of April 2026. Buffett has historically described 1.2x book as the level at which repurchases are clearly accretive to per-share intrinsic value. At 1.5x, the market is assigning a modest premium for the quality of the operating businesses and the equity portfolio.
Running a sum-of-the-parts analysis through the ValueMarkers screener framework gives three components:
First, the equity portfolio: Berkshire's listed holdings, dominated by Apple, Bank of America, American Express, and Coca-Cola (KO, which yields 3.0%), were worth roughly $310 billion at end of 2024.
Second, the operating businesses: on a normalized earnings basis of around $30 billion in operating profit, applying an 18-20x multiple gives an operating business value of $540-600 billion.
Third, the cash: $334 billion in cash and short-term investments at end of 2024.
Summing these components and subtracting the market capitalization gives an implied premium or discount. At the current price, the market is paying roughly 10-15% above the sum of the parts, which reflects the "Buffett premium." Whether that premium survives fully under Abel is the open question.
What Serious Investors Should Track
If you hold BRK.B for the Abel era, three numbers matter most.
Earnings-per-share growth on operating income, stripping out investment gains and losses. This measures whether the subsidiaries are compounding.
Cash deployment. The $334 billion cash pile earns around 5% in T-bills, roughly $16 billion per year. The opportunity cost of not deploying that into businesses earning 12-15% returns is real. Each year Abel does not find a large acquisition is a year the cash earns below the cost of capital implied by the business.
Book value growth per share. Buffett used this as his primary measure for decades. Over the past five years, BRK's book value per share has grown at roughly 12.4% annualized. Maintaining that under Abel is the benchmark.
The Graham Number approach gives an independent perspective: for a company with earnings per share around $24 and book value per share near $320, the Graham Number is approximately $415. BRK.B's current price is above that threshold, which tells value investors they are paying for quality and future growth, not a statistical bargain.

Frequently Asked Questions
what happens if the stock market crashes
In a stock market crash, Berkshire Hathaway typically holds up better than the index because of its diversified operating businesses, large cash position, and ability to deploy capital when prices fall. In 2008, BRK.B fell roughly 31% versus the S&P 500's 37% decline. Abel has emphasized that Berkshire's balance sheet is built to survive any foreseeable financial crisis without accessing external capital. The cash reserve exists precisely for these moments.
what time does the stock market open
The U.S. stock market opens at 9:30 a.m. Eastern Time on trading days. BRK.B is listed on the NYSE and trades during regular market hours. Pre-market activity in BRK.B is typically thin given Berkshire's size and the long-term orientation of most shareholders. The most meaningful price movements in BRK.B tend to follow the release of quarterly operating earnings and the annual shareholder letter.
are stock markets closed today
U.S. stock markets are closed on 10 federal holidays each year. For 2026, those dates include January 1, January 19 (MLK Day), February 16 (Presidents Day), April 3 (Good Friday), May 25 (Memorial Day), June 19 (Juneteenth), July 3 (observed), September 7 (Labor Day), November 26 (Thanksgiving), and December 25. Berkshire's annual meeting is in Omaha in early May, always on a Saturday, and does not affect trading days.
what time does the stock market close
The U.S. stock market closes at 4:00 p.m. Eastern Time on regular trading days. Extended after-hours trading continues until 8:00 p.m. Eastern on most platforms. For BRK.B specifically, the stock rarely gaps significantly in after-hours unless Berkshire releases earnings or makes a major acquisition announcement outside regular trading hours.
when does the stock market open
The stock market opens at 9:30 a.m. Eastern Time. For international investors watching Berkshire, that is 2:30 p.m. London time, 10:30 p.m. Tokyo, and 6:30 a.m. Los Angeles. Abel participates in the annual shareholder meeting broadcast each May, which is the closest thing to a quarterly investor call that Berkshire offers given its policy of no quarterly earnings calls.
why is the stock market down today
The stock market falls when aggregate selling pressure exceeds buying pressure across broad indices. For Berkshire specifically, declines are usually tied to one of three triggers: a selloff in Apple, which is Berkshire's largest equity holding; concerns about the insurance float model when catastrophic losses rise; or broad index declines that pull all large caps lower. Abel's ability to communicate clearly during downturns will be tested when the next major market correction arrives.
