Berkshire Hathaway can repurchase its Class A and Class B shares when its CEO, after consulting the Board Chair, judges that the shares are selling below the company’s conservatively estimated intrinsic value. The program does not require Berkshire to buy shares: it preserves a $30 billion liquidity floor and sets no minimum purchase amount.
How Berkshire Hathaway’s repurchase program works
Berkshire’s current filing says repurchases may take place in the open market or through privately negotiated transactions. The CEO makes the value judgment after consulting the Chairman of the Board. Berkshire will not repurchase shares if doing so would reduce consolidated cash, cash equivalents, and U.S. Treasury bill holdings below $30 billion. The filing states no minimum, maximum, expiration date, or obligation to buy a particular number or dollar amount. Berkshire Hathaway’s second-quarter 2026 Form 10-Q
The filing reported $4.8 billion of treasury stock acquired in the first six months of 2026, most of it during the second quarter. That is activity for the period ended June 30, 2026—not a schedule or promise of future purchases.
How a buyback can increase value per remaining share
A repurchase uses company cash to retire shares. The business has less cash afterward, but each remaining share represents a larger fraction of the company. That change benefits continuing shareholders only if the cash spent is less than the value of the shares retired, and if the cash would not have created more value elsewhere.

For example, if management estimates a share’s intrinsic value at $100 and repurchases it for $80, the company has paid less than the estimated value of the claim it retires. The remaining owners’ proportional stake increases. This arithmetic does not mean the operating businesses become more productive, that total intrinsic value rises, or that the market price must increase.
Buffett’s illustration of the limited effect
In his 1999 shareholder letter, Warren Buffett illustrated the scale of the effect: a repurchase of 2% of shares at a 25% discount to per-share intrinsic value produces at most a ½% gain in intrinsic value per share. He noted the gain would be smaller if the cash could instead be used for value-building investments. This is a historical hypothetical, not a forecast of Berkshire’s current repurchases. Buffett’s 1999 shareholder letter
Why the purchase price matters to continuing shareholders
If Berkshire pays more than a share is worth, it transfers excess value from shareholders who remain to those who sell. Buffett captured the problem in the 1999 letter: “Buying dollar bills for $1.10 is not good business for those who stick around.” That letter also stated the historical policy of repurchasing only when Berkshire believed its shares were selling well below conservatively calculated intrinsic value. The current filing describes the program and decision process; the 1999 wording should not be mistaken for a newly issued policy statement.
Intrinsic value is not market price or book value
Berkshire’s Owner’s Manual defines intrinsic value as “the discounted value of the cash that can be taken out of a business during its remaining life.” It is an estimate, not an observable fixed number: estimates can change as interest rates and cash-flow expectations change, and informed evaluators may reasonably disagree.

The manual describes book value as easy to calculate but of limited usefulness, particularly because the book values of controlled businesses can differ substantially from their economic value. The cited sources do not disclose a precise intrinsic-value estimate or a fixed price-to-book trigger for Berkshire’s buybacks.

A lower share count alone does not prove that a buyback created value. For Berkshire, the relevant questions are:
- Is the market price below management’s conservative estimate of intrinsic value?
- How many shares are expected to be retired, and how does that change each remaining share’s proportional claim?
- Would the purchase leave consolidated cash, cash equivalents, and U.S. Treasury bills at or above the $30 billion floor?
- Could investing in Berkshire’s operating businesses or another opportunity create more value than repurchasing shares?
The answer depends on the price paid, the value of the shares retired, the liquidity Berkshire retains, and the opportunity cost of the cash. A repurchase can be sensible when those conditions align; it is not automatically beneficial simply because fewer shares remain outstanding.
