In his first annual letter to shareholders as chief executive of Berkshire Hathaway, Greg Abel delivered a message of assurance to investors: the conglomerate’s long-standing culture of financial conservatism, capital discipline, and decentralized management will remain intact following the leadership transition from Warren Buffett.

“I am honored by our Board’s decision to appoint me CEO of Berkshire and humbled to succeed Warren as I write my first annual letter to you,” Abel wrote in the annual report released Saturday alongside quarterly earnings. “Warren is obviously a very hard act to follow.”

Abel, 63, formally assumed the CEO role at the start of 2026 after Buffett, 95, stepped down and remained chairman. The tone of the letter, first published by CNBC, emphasized institutional continuity rather than strategic redirection. Abel framed Berkshire’s core principles as enduring: maintaining financial strength, allocating capital with discipline, and preserving the conglomerate’s reputation for integrity.

“We maintain a fortress-like balance sheet, ensuring Berkshire’s foundation is never compromised,” he wrote. “We preserve this financial strength by using debt sparingly and prudently. Our substantial liquidity enables us to meet our obligations even under the most adverse conditions and to respond swiftly when opportunities arise.”

Cash, capital allocation, and portfolio oversight

Berkshire ended 2025 with $373.3 billion in cash and equivalents — a record level that has drawn attention from investors seeking clues about deployment strategy. Abel described the cash pile as strategic flexibility rather than defensive retrenchment, characterizing it as “dry powder” that allows the company to move decisively without jeopardizing resilience.

He pushed back against any interpretation that the size of the cash balance reflects a retreat from investing. Instead, he reiterated that Berkshire’s hurdle remains value creation: retained earnings must generate more than one dollar of market value for each dollar kept inside the company.

“Our approach to cash dividends continues to be that Berkshire will not pay dividends so long as more than one dollar of market value for shareholders is reasonably likely to be created by each dollar of retained earnings,” Abel wrote, noting the board reviews the policy annually.

The new CEO also resolved a key governance question by confirming he will directly oversee Berkshire’s equity portfolio.

“At Berkshire, equity investments are fundamental to our capital allocation activities; responsibility ultimately resides with me as CEO,” he wrote.

Berkshire’s publicly traded holdings remain concentrated in a small group of U.S. companies that Abel said are expected to compound value over decades, including Apple, American Express, Coca-Cola, and Moody’s. Notably absent from that list was Bank of America, which ranked as Berkshire’s third-largest holding at the end of 2025.

Abel reiterated that the portfolio will remain concentrated and turnover limited, though Berkshire would “significantly adjust” a position if long-term economic prospects change. Ted Weschler will continue managing roughly 6% of the equity portfolio, including investments previously overseen by Todd Combs, who recently departed for JPMorgan.

Abel emphasized that the same analytical discipline applies across the capital stack: acquisitions of entire businesses, minority equity stakes, and share repurchases are evaluated under a unified value framework.

“We will assess value carefully, act patiently, and hold for the long term — preferably forever,” he wrote.

Leadership transition and long-term orientation

Internally, Abel has long been viewed as an operationally hands-on executive with deep familiarity across Berkshire’s sprawling subsidiaries. A native of Edmonton, Alberta, he joined Berkshire in 2000 after its acquisition of MidAmerican Energy and later became chief executive of that unit in 2008. His tenure within the conglomerate spans 25 years.

In the letter, Abel underscored his intention to serve as a long-term steward. “Our owners’ time horizon extends beyond the tenure of any individual CEO,” he wrote. “I will not be your CEO for the next 60 years as simple arithmetic makes that – shall we say – an ambitious plan. However, 20 years from now … my intention is that you – or your descendants – will be proud that your company is even stronger.”

He also sought to reassure shareholders that Buffett remains engaged. According to Abel, Buffett continues to come into the office five days a week and provides ongoing input as chairman, reinforcing the sense of continuity during the transition.

In keeping with Berkshire’s long-standing communications philosophy, Abel made clear the company will not adopt Wall Street’s quarterly earnings call model.

“We concentrate on quality, not frequency,” he wrote. “If a significant issue arises, you will hear from me, but it will not be through quarterly commentary, given our long-term horizon.”

Together, the letter positions Berkshire not as an institution entering a new era of experimentation, but as one committed to preserving the structural principles that defined it under Buffett: a fortress balance sheet, concentrated long-duration investments, and a corporate culture built around autonomy, trust, and patient capital.

The United States and Israel launched coordinated military strikes on Iran on Saturday, targeting senior political and military leaders in an operation that has rapidly expanded into a regional confrontation and injected fresh volatility into global energy markets.

President Donald Trump described the assault as a pre-emptive move to eliminate imminent threats and prevent Tehran from obtaining a nuclear weapon. In a video message, he warned that “bombs will be dropping everywhere” and urged Iranians to seek shelter, adding that once operations conclude, they should “take over your government.”

Israeli Prime Minister Benjamin Netanyahu said the joint operation would create the conditions for Iranians to “take their destiny into their own hands.” Defense Minister Israel Katz called it a pre-emptive strike designed to remove strategic threats to Israel.

Tehran condemned the attacks as illegal and unprovoked. Iranian forces responded with missile launches against Israel and several Gulf Arab states hosting U.S. bases, broadening the theatre of confrontation. Gulf governments reported intercepting missiles, while explosions were heard in parts of the United Arab Emirates and Bahrain, home to the U.S. Fifth Fleet.

Sources familiar with the situation said Iranian Defense Minister Amir Nasirzadeh and Revolutionary Guards commander Mohammed Pakpour were killed in Israeli strikes, alongside other senior commanders. If confirmed, the removal of top-level military leadership would represent one of the most significant blows to Iran’s command structure in decades.

Iran’s Revolutionary Guards said retaliation would continue until “the enemy is decisively defeated,” and warned that all U.S. bases and interests in the region are within range.

The Pentagon named the first phase of the operation “Operation Epic Fury,” focusing initially on high-value leadership and security targets. The strikes followed the collapse of indirect nuclear negotiations mediated by Oman earlier in the week.

Oil markets brace for supply disruption

Beyond the military dimension, the confrontation is reverberating through global commodity markets. Iran is the third-largest producer in the Organization of the Petroleum Exporting Countries and accounts for roughly 4.5% of global crude supply. More critically, a far greater share of global oil shipments transits the Strait of Hormuz, the narrow maritime chokepoint along Iran’s southern coast.

Any sustained military escalation that threatens tanker traffic through Hormuz could remove millions of barrels per day from international markets, either through physical disruption or precautionary shipping suspensions. Even without a formal blockade, heightened insurance costs, rerouted shipping, and suspended cargoes can materially constrain supply.

Energy traders have already priced in geopolitical risk premiums. Analysts warn that, absent rapid de-escalation, oil prices could spike sharply when markets reopen, feeding into global inflation pressures and complicating central bank policy decisions in major economies.

Two sources close to OPEC+ discussions told Reuters that the producer alliance is considering a larger-than-planned output increase at its meeting on Sunday in an effort to stabilize markets. The move would be aimed at offsetting potential supply losses and signaling that spare capacity remains available.

Saudi Arabia and the United Arab Emirates have already raised exports in anticipation of supply stress, according to industry sources. Both countries hold significant spare production capacity within OPEC+, positioning them as primary stabilizers in the event of a prolonged disruption.

The scale of any emergency increase will be closely scrutinized. While Riyadh and Abu Dhabi can ramp up production, sustained conflict affecting Hormuz would present logistical constraints that additional barrels alone may not fully resolve.

Broader economic and geopolitical consequences

A sustained surge in crude prices would ripple across global supply chains. Higher energy costs could lift transportation, manufacturing, and food prices, slowing growth in import-dependent economies while boosting revenues for major exporters.

Airlines have already cancelled or rerouted flights across parts of the Middle East, and some oil majors and trading houses have paused shipments through the Gulf pending further security assessments. Insurance premiums for vessels transiting the region are expected to rise sharply.

Strategically, the confrontation marks once again the fragility of the Gulf security architecture. The region hosts dense concentrations of energy infrastructure, desalination plants, and U.S. military assets within relatively short missile range. Even limited strikes risk triggering cascading economic consequences.

The immediate effect of a military confrontation centered on Iran is a global economic risk, with oil markets once again at the frontline of geopolitical shock. It is hoped it doesn’t escalate into a prolonged conflict affecting energy corridors at scale.
