What it means
The simplest version is a dual class structure: ordinary investors buy Class A shares with one vote each, while founders and early insiders hold Class B shares carrying ten votes each. Both classes usually receive the same dividend per share and the same payout if the company is sold, so the difference is about power rather than money.
Class B shares typically convert automatically into Class A shares when they are sold to an outsider, which stops the extra votes from being traded away. Companies classify shares because the alternative, selling voting control alongside capital, can force short-term decisions on a business with a long-term plan.
A founder who wants to spend heavily on research for five years may prefer to raise money without inviting a proxy fight in year two. Family businesses and media companies have used the same logic for decades to protect editorial or strategic independence.
Classification is not always about votes. Some companies issue tracking shares whose dividend depends on the results of one division, and private companies commonly create alphabet shares so that different shareholder groups can be paid different dividends in different years.
Preference shares, which rank ahead of ordinary shares for dividends and on a winding up, are another form of classification even though they are rarely described that way. The nuance investors care about is the gap between economic ownership and voting power.
When insiders own a fifth of the equity but control most of the votes, minority shareholders have little practical recourse if they disagree with strategy, and some stock indices restrict or exclude such companies. Many modern charters now include a sunset provision that collapses all shares into a single class after a fixed period or once a founder's holding falls below a threshold.
In practice
Real-world examples.
Example
A social media company lists with Class A shares sold to the public at one vote each and Class B shares held by its two founders at ten votes each. Public investors supply nearly all the capital, but the founders retain enough votes to appoint the board and reject any offer for the business.
Example
A family newspaper group creates Class B shares that convert to Class A on any sale outside the family. When one branch of the family sells its holding to an institution, those shares automatically lose their extra votes, and control stays with the branch that stayed invested.
Example
A private consultancy issues A, B and C ordinary shares to three partner groups so the board can declare different dividends to each group depending on the profit their practice area generated. All three classes rank equally on a sale, which keeps the eventual exit simple.
Formula
Calculation
Voting power is calculated from votes rather than share counts:
Voting power of a class = (shares in that class x votes per share) / total votes outstanding
Consider a company with two classes:
Class A: 8,000,000 shares x 1 vote = 8,000,000 votes
Class B: 2,000,000 shares x 10 votes = 20,000,000 votes
Total votes = 8,000,000 + 20,000,000 = 28,000,000 votes
The founders, who hold all the Class B shares, control 20,000,000 / 28,000,000 = 71.4% of the votes. Their economic ownership, however, is only 2,000,000 / 10,000,000 total shares = 20% of the company. Outside investors own the remaining 80% of the economics but cast just 8,000,000 / 28,000,000 = 28.6% of the votes, so they cannot pass an ordinary resolution over the founders' objection.Case study
Seen in the real world.
Lumen Orchard Systems is a fictional company used purely as an illustrative example. Its two founders took the business public after eleven years, selling 8,000,000 Class A shares to investors while keeping 2,000,000 Class B shares with ten votes each, exactly the structure in the calculation above.
Three years after listing, a larger competitor offered a 35% premium to the market price. A majority of Class A holders wanted the deal, but the founders held 71.4% of the votes and refused, arguing that a product launched the previous quarter would be worth more than the offer within two years. Several institutional shareholders complained publicly, and one index provider capped the weight it would give the stock.
The charter also contained a sunset clause converting all Class B shares to Class A ten years after listing. In this illustrative case the founders were proved right on the product, but the episode shows the real bargain classified shares create: outside investors accept limited influence in exchange for backing a management team they must be willing to trust for years.
Watch out
Common mistakes.
- Assuming Class A shares are always the superior class. The naming is a company choice, and in plenty of structures Class B carries the extra votes, so you have to read the charter rather than the letter.
- Confusing voting power with economic ownership. A founder can control most of the votes while owning a small minority of the shares and receiving a small minority of the dividends.
- Thinking classification affects the value received in a takeover. Most charters pay all classes the same amount per share on a sale, so the difference is influence over whether the sale happens at all.
Questions
People also ask.
Do classified shares always mean unequal voting rights?
No, some classifications create differences in dividends, conversion rights or which division's results the shares track, with voting rights left identical.
Can a company remove its share classes?
Yes, usually by a charter amendment that requires approval from the class being reduced, or automatically through a sunset clause written in at the time of listing.
Why do some index funds dislike classified shares?
Because index investors cannot sell an underperforming holding easily, so voting is their main tool, and a structure that removes that tool weakens their ability to press for change.
