The Berkshire Thread (Part 3): Berkshire Hathaway (NYSE: BRK.B) — The World’s Most Famous Investor Just Handed Over the Keys

The Arc That Brought Us Here

Two weeks ago, we opened this arc with Coca-Cola — the stock Buffett bought in 1988 and has never touched since. Last week, Johnson & Johnson: the defensive compounder hiding in plain sight, a business that’s raised its dividend for over six decades and barely flinches when markets panic.

Both pieces were about Buffett’s fingerprints — his philosophy of buying durable businesses at fair prices and letting time do the compounding. KO was the personal holding, the most quoted example of his investment faith. J&J was the institutional manifestation of that philosophy — a company even Buffett doesn’t own, but would recognise instantly.

This week, we arrive at the man himself. Or rather, the machine he built.
Berkshire Hathaway. The capstone. And the most interesting succession question in investing today.

First: What Berkshire Actually Is

Most people, including a surprising number of investors, think of Berkshire Hathaway as a fund — a vehicle for owning a portfolio of public stocks the way a managed fund does.

It isn’t. Not even close.

Berkshire Hathaway is an operating conglomerate — a holding company that owns entire businesses outright, not just stakes. It owns:

• GEICO — one of the largest auto insurers in the United States
• BNSF Railway — the second-largest freight railroad in North America
• Berkshire Hathaway Energy — a diversified energy utility with operations across the US, UK, and Canada
• Manufacturing, Service & Retail businesses — from Duracell batteries to See’s Candies to Dairy Queen
• Public equity stakes — Apple, Bank of America, Chevron, American Express, Occidental Petroleum, and (as of 2026) Alphabet

The public stock portfolio is the visible part. The operating businesses are the engine.

This distinction matters because it changes everything about how you analyse the company — and why the transition from Buffett to Abel isn’t the same as a great fund manager leaving their fund.

The Insurance Float: The Structural Moat That Doesn’t Leave with Buffett

Here is Berkshire’s most underappreciated competitive advantage, and the one that most clearly answers “is this just a Buffett personality play?”

It’s called the float.

When insurance companies collect premiums, they hold that money before paying any claims. That gap — between receiving premiums and paying out — creates a pool of capital they can invest. It’s effectively an interest-free loan from policyholders to the insurer.

Berkshire’s insurance float sat at approximately $176.9 billion as of 31 March 2026. That is an extraordinary number. And unlike most insurers who might occasionally lose money on underwriting (meaning the float comes at a cost), Berkshire consistently makes money on underwriting as well. In Q1 2026, GEICO ran a combined ratio of 87.3% — meaning for every dollar collected in premiums, Berkshire paid out only 87.3 cents in claims and expenses. The other 12.7 cents was profit, in addition to whatever returns the float generated from investment.

The float doesn’t belong to Buffett. It belongs to the structure — the insurance businesses, the underwriting discipline, the decades of operational culture baked into GEICO, General Re, and Berkshire Hathaway Reinsurance. Greg Abel didn’t just inherit a name; he inherited a free $176.9 billion pool of capital that renews every year as long as Berkshire keeps underwriting profitably.

That’s the moat. And it stays.

These structural advantages form the foundation Abel inherited. The open question is no longer whether the machine still works — it does — but how he will choose to deploy its enormous financial capacity.

Greg Abel and the $397 Billion Question

On 1 January 2026, Greg Abel became CEO of Berkshire Hathaway. Warren Buffett remains Chairman and the largest individual shareholder. The transition had been telegraphed for years, yet the formal handover still carried symbolic weight. Shares softened in the immediate days around the changeover as markets processed the reality of “a very hard act to follow,” though the larger succession discount had already been absorbed earlier in 2025.

Abel, for his part, hasn’t tried to be Buffett. His early communications have been direct: he won’t make major changes to the philosophy or structure. The operating culture, as best as institutional culture can be preserved, remains intact.

But here’s where it gets interesting.

As of 31 March 2026, Berkshire was sitting on approximately $397 billion in cash, cash equivalents and short-term U.S. Treasury bills — more than Apple, Amazon, Alphabet and Microsoft combined at the time. That figure had grown steadily as Buffett found fewer and fewer acquisitions that met his price threshold in an expensive market. He was, in effect, waiting.

Abel has started to move.

Early in his tenure the company closed the roughly $9.5 billion acquisition of Occidental’s chemicals business (OxyChem). More visibly, Berkshire committed US$10 billion to Alphabet via private placement as part of Alphabet’s large capital raise to fund AI infrastructure — one of Berkshire’s largest single equity deployments in recent years, and a clear signal that Abel’s investment instincts are not purely old-economy. Alphabet fits the Berkshire template: dominant market position, durable cash flows, structural pricing power. Yet it is also a distinctly modern, AI-infrastructure call that Buffett had largely avoided for years.

Together these moves show Abel is prepared to act. Yet even a $10 billion equity commitment and a nearly $10 billion acquisition remain modest relative to the total cash position. The central tension of the Abel era remains intact: the business model and structural advantages are secure, but the bulk of the war chest is still waiting to be put to work in a market where few assets look cheap.

What the Business Actually Earns

Numbers worth anchoring on (Q1 2026):

• Operating earnings: $11.35 billion, up 17.7% year-on-year, driven by insurance underwriting, BNSF, energy and manufacturing
• Insurance float: $176.9 billion (generating returns while underwriting remained profitable)
• Cash and short-term Treasuries: ~$397 billion (earning meaningful income in a still-elevated rate environment)
• The non-insurance operating businesses continued to grow, with manufacturing, service and retailing contributing solidly

Taken together, these figures show an operating engine that continues to compound while the large cash position itself has become a meaningful earnings contributor.

When rates are elevated, Berkshire’s cash pile becomes a quiet earnings engine. Every basis point of yield on nearly $400 billion is real money — an unusual situation for a company that benefits from the rate environment that pressures many others.

The Australian Investor Angle: BRK.A vs BRK.B

Here’s what most Australian retail investors still don’t fully appreciate: the B share exists and is fully accessible.

BRK.A, Berkshire’s Class A share, trades at roughly US$760,000–$770,000 per share as of late July 2026. It remains a practical barrier for most individual investors.

BRK.B is the economic equivalent but priced at approximately 1/1,500th of the A share — making it accessible through any standard brokerage platform that offers US equities. On platforms such as Stake, Superhero or Interactive Brokers Australia, BRK.B can be bought with no minimum beyond what you choose to invest.

A few other points Australian investors should keep in mind:

• No dividend, by design. Berkshire does not pay a dividend. Buffett’s longstanding logic (confirmed by Abel) is that if management can allocate retained earnings better than shareholders could after tax, retaining the capital is the more shareholder-friendly choice. For Australian investors this means no DRP, no franking credits, and no annual foreign income to declare in the usual sense — but it also means you own a business that compounds its capital internally.
• Foreign currency exposure. BRK.B is priced in USD. Movements in the AUD/USD rate affect your effective return in Australian dollars. A weaker AUD (common in risk-off periods) increases the AUD value of your holding; a stronger AUD compresses it. Worth monitoring, not obsessing over.
• Platform and structure access. Standard on most Australian platforms with US market access. Eligible for SMSF investment (obtain appropriate advice for your specific structure).

The Verdict

Berkshire Hathaway is not a bet on Warren Buffett. It never really was — that has been the misreading all along. It is a bet on a capital allocation machine built over six decades, with structural advantages (the float, the operating businesses, the culture of underwriting discipline and long-term ownership) that no individual departure can dismantle.

Abel is measured, experienced (he ran Berkshire Hathaway Energy for years), and clear-eyed. His early moves suggest he is prepared to deploy capital into quality businesses when the opportunity and the price make sense. The open question is whether markets will give him attractive entry points, or whether he will continue creating his own theses the way the Alphabet investment illustrates.

For Australian investors looking for a long-term, low-complexity US equity position that does not depend on any single sector or macro call, BRK.B remains worth serious consideration. It will not double in a year. It is not designed to. It is designed to compound quietly, survive downturns, and hand you more purchasing power a decade from now than most alternatives.

Buffett handed over the keys. The car was already built.
