What Are Class A Shares? Class A vs. Class B and C Stock
By Markets & Investing DeskUpdated Nov 10, 2026
Definition
Class A shares are a class of a company's common stock whose voting and economic rights are set by its charter and bylaws. The letter alone does not guarantee extra votes or control.
Key takeaways
- A dual-class structure separates economic ownership of shares from voting control over the board and major decisions.
- In the article's hypothetical, a founder with 10% of shares at 10 votes each controls about 52.6% of the votes.
- At Alphabet, public Class A shares carry one vote, insider Class B shares carry 10, and Class C shares carry none.
- Mutual fund Class A shares refer to fees, typically a front-end sales load, and have nothing to do with votes.
Class A shares are a class of a company’s common stock whose rights are set by that company’s charter and bylaws. Traditionally, Class A carries more voting power than other classes, but no law requires this. The letter only signals that the company has more than one class of stock. At one company, Class A is a closely held insider class with extra votes. At another, it is the ordinary publicly traded share with one vote, while a separate Class B holds control.
How Class A Shares Work
A company that issues more than one class of stock spells out each class’s rights in its corporate charter and bylaws. The usual differences are:
- Votes per share: one class may carry several votes per share, one vote, or none.
- Dividend rights: one class may be paid before another.
- Liquidation rights: one class may be paid ahead of others in a sale or wind-down.
- Convertibility: one class may convert into another, sometimes at more than one-for-one.
- Tradability: one class may be listed on an exchange while another is held privately.
The key distinction is between economic ownership and voting control. Owning a share of equity gives a claim on the company’s value. The votes attached to that share decide who elects the board and approves major decisions. A dual-class structure separates the two.
Hypothetical example of voting control: a founder holds 10 million Class B shares at 10 votes each, which gives 100 million votes. Public investors hold 90 million Class A shares at one vote each, which gives 90 million votes. The founder owns 10% of the shares (10 million of 100 million) but controls about 52.6% of the votes (100 million of 190 million). That is enough to outvote every public shareholder combined.
Why Companies Issue Class A Shares
The main reason is control. If a company had only one class of stock, an outside investor could buy enough shares to win board seats or force a sale. When insiders hold a class with extra votes per share, buying a majority of the tradable shares no longer gives control. This blocks hostile takeovers.
Supporters argue that insulating management lets it pursue long-term plans without pressure from shareholders focused on short-term results. Keeping the controlling shares out of public trading is also described as a way to reduce agency problems, where people put their own goals ahead of the company’s interests.
Traditional Class A shares can carry economic privileges as well:
- Dividend priority: holders are paid before other classes when dividends are declared.
- Liquidation preference: in a sale or exit, debt holders are paid first, then preferred Class A holders, then other shareholders from whatever remains.
- Enhanced conversion: some Class A shares convert into more than one ordinary share. Public shareholders generally cannot convert up into a higher-vote class.
Hypothetical conversion example: a CEO owns 100,000 Class A shares, each convertible into five common shares. The company is sold for $50 per common share. After conversion, the CEO holds 500,000 common shares, worth 500,000 × $50 = $25,000,000. Without the conversion feature, the same 100,000 shares at $50 would be worth $5,000,000. This assumes the sale price applies per common share after conversion.
Three Common Class A Structures
Traditional insider Class A
Founders, executives and directors own the shares, which usually carry superior voting rights and may include the privileges above. They are generally not sold to the public.
Technology-company Class A
Alphabet (Google’s parent) popularized a three-class design that other tech firms have adopted:
- Class A: publicly traded, one vote per share (ticker GOOGL).
- Class B: held mainly by insiders, 10 votes per share, not publicly traded.
- Class C: publicly traded, no voting rights (ticker GOOG).
Here Class A still outranks Class C because it can vote, but the control traditionally associated with Class A sits in Class B. Meta is another example where Class B shares carry more votes than Class A. Buying Class A stock in companies like these does not make an investor an insider or give meaningful control.
High-priced Class A
Some companies never split their stock, so a single Class A share becomes too expensive for many individual investors. Instead of splitting, the company creates a Class B share that sells for a fraction of the price. As a hypothetical, a Class A share might cost $3,000 and carry 100 votes, while a Class B share costs $120 and carries one vote. That works out to about $30 per vote for Class A and $120 per vote for Class B. Berkshire Hathaway uses this general pattern, with BRK.A and the lower-priced BRK.B.
Class A vs. Class B vs. Class C Stock
The letters have no fixed meaning across companies. Some common patterns:
| Structure | Class A | Class B | Class C |
|---|---|---|---|
| Traditional | Insider, extra votes, possible preferences | Public, fewer votes | Rare |
| Alphabet-style tech | Public, one vote | Insider, 10 votes | Public, no vote |
| High-priced (Berkshire-style) | Expensive, full votes | Cheaper, reduced votes | Not used |
For a stock with both Class A and Class C listed, such as Alphabet, the choice is mostly about whether you want a vote. Both classes represent the same company but trade at separate market prices that can differ slightly. When you compare classes with a stock screener, check which ticker each result refers to.
Limitations of Class A Shares
- Public Class A shares may carry little real influence. If insiders hold a high-vote class, public voters cannot change the board, block a sale or reverse management decisions.
- Weaker accountability. The same insulation that protects long-term plans also protects underperforming management from shareholder pressure.
- Rights are company-specific. The charter, bylaws and the share-class section of the company’s annual report or proxy statement are the binding sources.
- Price is not a guide to rights. A more expensive class does not automatically carry proportionally more votes or better economics.
Not to Be Confused With Mutual Fund Class A Shares
Mutual funds also label share classes A, B and C, but these labels describe fees, not votes. Fund Class A shares typically charge a front-end sales load when you buy. Class B shares typically charge a deferred sales charge if you sell within a set period. Class C shares typically have no front-end load but higher ongoing charges.
The Bottom Line
Investors buying any stock labeled Class A should check what that label means at that specific company. The charter, bylaws and the share-class section of the annual report or proxy statement set the binding rights. A higher price or the letter A does not guarantee more votes, better economics or real influence over management.
