Class A, B, and C shares of the same company have different rights.

Remember this first
First, 3 things to remember
- 1A, B, and C are names designated by the company, not standardized classes of rights.
- 2The equity stake for profit sharing and the voting rights ratio can differ.
- 3Common stock, preferred stock, ADRs, REITs, and warrants are not on the same classification axis.
Common stock does not always equate to one share, one vote.
Common stock represents an equity stake in a company's residual profits and assets. It often carries voting rights and eligibility for dividends if declared, but there are also non-voting common shares or classes with multiple votes.
In a dual-class structure, founders and others can maintain voting power greater than their economic stake. While this can support long-term management continuity, it also carries the risk that general shareholders may find it difficult to influence management changes or transaction terms.
Specific examples of Alphabet filings
According to Alphabet's 2025 annual report, they are classified as follows. This is a disclosure example for that specific company and is not a rule applicable to A, B, and C shares of all companies.
| Class | Voting rights and trading classification |
|---|---|
| Class A · GOOGL | 1 votes per share |
| Class B | 10 votes per share; distinguish from classes listed on general exchanges. |
| Class C · GOOG | No voting rights, except for legal exceptions |
Price differences are not necessarily arbitrage opportunities
Even for two classes of the same company, prices may differ based on dividends, conversion, voting rights, liquidity, and index inclusion demand. Do not assume they can be freely exchanged for one another at a fixed ratio.
A class with a lower share price may represent a smaller unit of economic interest. Just as you would not judge a company as cheap based solely on the price of one share, compare prices between classes by accounting for rights and conversion conditions. There is no general rule that Class A is for individuals and Class B is for insiders.
Distinguish various securities at a glance
ADRs are trading and depositary structures, REITs are based on business and tax law requirements, classes refer to stock rights, and warrants are contractual rights. Therefore, they are not mutually exclusive categories. REITs can also issue common and preferred stock.
| Category | Risks and rights to check first |
|---|---|
| Common stock | Actual terms of residual equity, dividends, and voting rights. |
| Preferred stock | Priority, dividend suspension, call, and conversion |
| Dual-class share structure | Voting, conversion, and dividend rights. |
| ADR·ADS | Underlying share ratio, depositary agreement, exchange rate, and fees |
| REIT | Real estate, lending business, borrowing, and dividend sustainability |
| Warrants | Exercise price, period, maturity, and mandatory redemption. |
Documents to check before placing an order
Review the company's articles of incorporation, prospectus, and the share capital notes in the annual report. Check for class conversion conditions, whether voting rights change upon a founder's sale or death, and if separate consent is required for specific resolutions.
Suffixes and dot or dash notations can vary by brokerage. Checking the company name, class, exchange, and security identification information along with the ticker can reduce the risk of ordering the wrong security.
You should not make such assumptions
“Class A is always 1 votes and Class B is always 10 votes.”
Determined by each company's articles of incorporation. The Alphabet case cannot be applied directly to other companies.
Check what you have read.
- Have you checked the voting rights in the articles of incorporation?
- Have you distinguished between economic interest and voting rights?
- Have you checked if it is convertible?
- Is the class and exchange correct?
