The Real Differences Between Berkshire Hathaway Class a and Class B Shares

Berkshire Hathaway remains one of the most unique entities in the global financial landscape, largely due to its distinct dual-class stock structure. For the uninitiated investor, the massive price discrepancy between Class A (BRK.A) and Class B (BRK.B) shares can be jarring. While Class A shares trade at a price comparable to the cost of a luxury home, Class B shares are priced to be accessible to the average retail investor.

Despite the vast difference in share price, both classes represent ownership in the same underlying conglomerate, which holds massive stakes in companies like Apple, American Express, and Coca-Cola, alongside wholly-owned subsidiaries like GEICO and BNSF Railway. Understanding the technical and strategic nuances between these two share classes is essential for any investor looking to gain exposure to the compounding machine built by Warren Buffett and Charlie Munger.

Core Comparison of BRK.A and BRK.B

The primary distinctions between the two classes of stock lie in their price, voting power, and conversion capabilities.

The Historical Origin of Class B Shares

For decades, Berkshire Hathaway existed only as a single class of stock. Warren Buffett famously resisted splitting the shares, arguing that a high stock price attracts long-term investors who view themselves as business owners rather than short-term speculators. By the mid-1990s, however, the price of a single Class A share had climbed toward $30,000, creating a problem in the financial markets.

In 1996, several investment promoters attempted to create "unit trusts" that would buy Class A shares and then sell fractional "units" to the public for a high fee. These promoters intended to market these trusts as a way for small investors to own a piece of Berkshire. Buffett viewed these trusts as predatory, believing they would charge excessive commissions and mislead naive investors using Berkshire's past performance.

To thwart these unit trusts, the Board of Directors issued Class B shares in 1996. Originally priced at 1/30th of a Class A share, these new shares allowed investors to buy into the company directly without paying high fees to middlemen. This move protected the company’s reputation and provided a low-cost entry point for the "mom and pop" investors who admired the company's philosophy.

The Evolution of the 1:1,500 Ratio

The relationship between Class A and Class B shares changed significantly in 2010. When Berkshire Hathaway acquired the Burlington Northern Santa Fe (BNSF) railroad, the company needed to issue more shares to facilitate the deal and provide BNSF shareholders with a manageable stock for their holdings.

To make the shares even more liquid and accessible, Berkshire performed a 50-for-1 split on the Class B shares. Before this split, one Class A share was worth 30 Class B shares. After the split, the ratio became 1 to 1,500. This means that 1,500 shares of BRK.B represent the same economic interest in the company as one share of BRK.A.

This ratio is a critical number for investors to remember. If BRK.A is trading at $600,000, the "fair value" for BRK.B should theoretically be $400. While market forces occasionally cause small deviations, the two classes generally move in lockstep because of the conversion mechanism described later in this analysis.

Price and the Barrier to Entry

The most visible difference is the sheer cost of entry. As of early 2025, Class A shares have reached astronomical prices, often exceeding $750,000 per share. This high price acts as a natural filter. It discourages day trading and volatility because the high "ticket price" requires a level of conviction and capital that short-term speculators rarely possess.

Class B shares, on the other hand, are priced similarly to other major blue-chip stocks, usually between $400 and $600. This makes it possible for an investor to start a position with a relatively small amount of savings. It also allows for much finer control over portfolio weighting. If an investor wants to rebalance their portfolio by selling $5,000 worth of Berkshire stock, they can easily sell 10 shares of Class B. If they only owned one share of Class A, they would be forced to sell their entire position—worth hundreds of thousands of dollars—or nothing at all.

Voting Rights and Governance Power

While both classes offer an economic stake in the company, their influence on corporate governance is vastly different. A single share of Class A stock carries one full vote. In contrast, a share of Class B stock carries only 1/10,000th of a vote.

To put this in perspective, even though it takes 1,500 Class B shares to equal the economic value of one Class A share, those 1,500 Class B shares only carry 1,500/10,000th (or 15%) of the voting power of a single Class A share.

For the vast majority of retail investors, this difference is academic. Most individuals holding a few hundred shares do not have enough voting power to influence a company with a market cap approaching a trillion dollars. However, for institutional investors or activist shareholders, the Class A shares are the only way to exert meaningful pressure on the Board of Directors or participate in major corporate decisions.

Despite the lower voting power, Class B shareholders are still entitled to attend the "Woodstock for Capitalists"—the famous Berkshire Hathaway annual shareholder meeting in Omaha, Nebraska. Holding even a single share of Class B grants the owner the right to listen to the management's insights and participate in the company's unique culture.

The One Way Street of Convertibility

A unique feature of Berkshire's capital structure is the conversion privilege. Holders of Class A shares have the right to convert their shares into an equivalent number of Class B shares at any time. Specifically, one Class A share can be exchanged for 1,500 Class B shares.

However, this is a "one-way street." Class B shareholders do not have the right to convert their holdings into Class A shares. If an investor owns 1,500 shares of Class B and wishes to own a Class A share, they must sell their Class B shares on the open market and use the proceeds to purchase Class A.

This conversion mechanism serves as a price floor for Class B shares. If Class B shares ever traded significantly lower than 1/1,500th of Class A, arbitrageurs would buy Class A shares, convert them to Class B, and sell the B shares for a profit. This constant potential for conversion keeps the two stock prices closely aligned in terms of their percentage moves.

Tax Implications and Estate Planning

One of the most practical reasons for high-net-worth individuals to hold Class B shares—or to convert their Class A shares into B—is estate planning.

In the United States, the IRS allows individuals to give a certain amount of assets to another person each year without triggering a gift tax. As of 2025, this annual exclusion is approximately $19,000 per recipient. If an investor owns only Class A shares worth $700,000, they cannot give a "piece" of that share to their children or grandchildren without dealing with complex fractional ownership or immediate tax consequences.

By converting a Class A share into 1,500 Class B shares, the investor gains flexibility. They can give 30 or 40 Class B shares to multiple family members, staying well within the annual gift tax exclusion limits. This makes Class B shares a superior tool for long-term wealth transfer and generational planning.

Liquidity and Trading Dynamics

Liquidity refers to how easily an asset can be bought or sold without affecting its price. Class B shares are significantly more liquid than Class A shares.

Because the price of Class B is accessible, millions of shares change hands every day. This high volume means that the "bid-ask spread"—the difference between what a buyer is willing to pay and what a seller is willing to accept—is usually only a few cents. For a retail investor, this ensures they can enter and exit positions quickly at a fair market price.

Class A shares have much lower trading volume. On some days, only a few hundred shares might trade. Because the price is so high, the bid-ask spread can be several hundred dollars. While this is a small percentage of the total share price, it means that Class A is less suited for anyone who might need to liquidate their position in a hurry. Class A is truly designed for the "buy and hold forever" mentality.

Performance Parity and the No-Dividend Policy

A common question among investors is whether one share class outperforms the other. Historically, the two have tracked each other very closely. Any minor outperformance by one class is usually temporary and driven by short-term supply and demand imbalances. Over a period of years, the percentage return on an investment in BRK.A will be nearly identical to an investment in BRK.B.

Neither share class pays a dividend. This has been a cornerstone of the company’s philosophy for decades. Management believes that the company can generate a higher return for shareholders by reinvesting earnings back into its various businesses or by acquiring new ones, rather than paying out cash to investors. Since the company’s inception, it has only paid a single dividend of 10 cents in 1967—a move that Buffett later joked was a mistake.

For investors who require income, the Class B shares offer a "synthetic dividend" option. Because they are priced at a few hundred dollars, an investor can sell a few shares every year to create their own cash flow while keeping the rest of their capital invested in the company. This is much harder to do with Class A shares.

Summary Comparison of Investment Logic

Choosing between BRK.A and BRK.B depends entirely on the investor's capital and objectives.

Choose Class A (BRK.A) if:

• You have more than $700,000 to invest in a single stock.
• You prioritize maximum voting rights and corporate influence.
• You want the prestige of owning the world’s highest-priced stock.
• You have zero intention of ever selling small portions of your holding.

Choose Class B (BRK.B) if:

• You are a retail investor with a standard brokerage account.
• You want the flexibility to add to your position over time (dollar-cost averaging).
• You need the ability to sell small portions of your investment for cash flow.
• You are involved in estate planning or gifting shares to family members.
• You value liquidity and tight bid-ask spreads.

For 99% of investors, Class B is the logical, practical, and efficient choice. It provides identical exposure to the company's earnings and growth without the prohibitive price tag or the rigid structure of Class A shares.

Frequently Asked Questions

Can I buy a fractional share of BRK.A?

Yes, many modern brokerages like Charles Schwab, Fidelity, and Robinhood allow investors to purchase fractional shares. This means you could technically invest $100 into BRK.A. However, you would not have the same direct voting rights as a full share owner, and for most people, simply buying BRK.B shares is a more straightforward way to achieve the same result.

Why won't the company split the Class A shares?

Management believes that a stable, high stock price attracts a higher quality of shareholder—specifically, those with a long-term horizon. They want to avoid the "churn" associated with lower-priced stocks that are often targeted by day traders and speculators.

Is the conversion from Class A to Class B a taxable event?

Generally, no. Converting Class A shares into Class B shares is considered a "recapitalization" for tax purposes and is typically not a taxable event in the United States. However, investors should always consult with a tax professional regarding their specific situation, especially if they are dealing with international tax laws.

Do Class B shareholders get the same discounts as Class A shareholders?

Yes. Berkshire Hathaway offers various shareholder perks, such as discounts on GEICO insurance and other subsidiary products, to owners of both share classes. Holding at least one share of either class also qualifies you for credentials to the annual meeting.

Which share class is more volatile?

In terms of percentage moves, they are remarkably similar. However, Class B can sometimes experience slightly higher volatility during peak market hours because of the higher volume of retail trading and the influence of algorithmic trading focused on lower-priced stocks.

Does the death of top leadership affect A and B shares differently?

No. Any news regarding the company's succession planning or leadership changes would affect the underlying value of the company, and therefore both share classes would react proportionally based on the market's assessment of Berkshire's future earnings power.

Conclusion

The distinction between BRK.A and BRK.B is a fascinating case study in corporate governance and market accessibility. Class A remains the "gold standard" for the ultra-wealthy and institutional giants, preserving the original vision of the company with full voting rights and an uncompromising price. Class B serves as the "people’s share," providing a flexible, liquid, and affordable entry into one of history's greatest wealth-creation engines. For the modern investor, the choice is less about performance and more about the practicalities of portfolio management and personal financial goals. Regardless of the letter after the ticker, an investment in Berkshire Hathaway is a bet on the long-term resilience and productivity of the American and global economy.
