Class A vs Class B Shares: What's Actually Different (Quick Answer + Examples)

Class A and Class B shares are two flavours of the same company’s common stock that carry different rights — most often, different voting power. The textbook setup: Class A is what trades publicly with one vote per share; Class B is held by founders and insiders with ten votes per share. The economics are usually identical, but the control isn’t.

The naming can flip company-to-company (Berkshire Hathaway reverses it, Fox does something different again), and the rights vary. Here’s the practical comparison, with concrete examples.

Quick comparison

The big asterisk: this naming convention isn’t universal. Berkshire Hathaway has Class A as the high-priced original, Class B as the lower-priced retail-friendly version — no dramatic voting-rights gap. Always read the company’s charter; the labels alone don’t tell you the rights.

What a dual-class structure actually does

A dual-class structure splits ownership into categories with different voting power but usually identical economic rights. Class A shares trade publicly and carry one vote each. Class B shares stay with founders, executives, and early backers, typically carrying ten votes each.

The point is to separate economic ownership from voting control. A founder might own 10–15% of total equity but control 50–60% of voting power through high-vote Class B shares. That lets a company raise hundreds of millions in public markets without surrendering strategic direction to activist investors or quarterly earnings pressure.

Most modern dual-class IPOs share four design choices:

• 10:1 voting ratio — Class B carries 10 votes, Class A carries 1.
• Equal economics — both classes get identical dividends and liquidation rights.
• Transfer-triggered conversion — Class B converts 1:1 to Class A if sold to anyone outside a permitted group (family, trusts, charities).
• Sunset provisions — increasingly common in post-2019 IPOs, automatically converting Class B to Class A after 7–10 years or upon founder departure.

The mechanics scale predictably. With a 10:1 ratio, a founder holding 20% of equity as Class B controls roughly 71% of votes when the remaining 80% is Class A. That math is what makes the structure attractive — and what makes proxy voting on Class A shares so much weaker than it looks at first glance.

Real examples: Meta, Alphabet, Snap, NYT

The cleanest way to understand dual-class shares is to look at the companies that use them.

Meta Platforms went public in 2012 with Class A (1 vote, ticker META, traded on NASDAQ) and Class B (10 votes, held by Mark Zuckerberg and early insiders, not traded). Zuckerberg controls roughly 55% of voting power with about 13% economic ownership — control that survived the rebrand from Facebook, the metaverse pivot, and the AI buildout, all decisions activist shareholders couldn’t block.

Alphabet runs a three-class structure: Class A (GOOGL, 1 vote), Class B (10 votes, held by Larry Page and Sergey Brin), and Class C (GOOG, 0 votes). The founders control about 51% of voting power with under 6% of equity. Alphabet created the non-voting Class C in 2014 specifically so it could fund stock-based acquisitions — like the $12.5B Motorola Mobility deal — and grant employee equity without diluting founder votes.

Snap took the structure to its extreme at its 2017 IPO: public investors got Class A shares with zero votes. Founders Evan Spiegel and Bobby Murphy retained roughly 88% of voting power with under 5% economic ownership. The S&P 500 responded by adopting rules against non-voting shares, and Snap was excluded from the index. Stock fell from $27 to about $5 within 18 months before recovering — a useful reminder that founder control doesn’t substitute for execution.

The New York Times runs the longest-standing dual-class structure in major US media. Class A holders (NYT) elect 9 of 13 directors with 1 vote per share. Class B shares — 9 votes each, held by the Sulzberger family trust — elect 4 directors and carry veto power. The family owns under 2% of economic value but controls roughly 70% of voting power. That structure underwrote the Times’ multi-year digital subscription pivot and its $550M acquisition of The Athletic in 2022, both of which would have been harder to push through under quarterly-earnings discipline.

Class A vs Class B in private companies

The dual-class structure looks very different before a company goes public. In a private US C-corporation, the Class A vs Class B distinction usually maps to founders vs investors — and “Class B” doesn’t automatically mean “more votes.” Often it’s the opposite of the public-company pattern.

Three common private-company patterns:

• Founder-controlled startups — Class A is founder common stock with super-voting rights (e.g. 10 votes). Class B is the common stock issued to employees, advisors, and angels with 1 vote. This is the structure most modern Silicon Valley startups carry into IPO.
• Investor preferred + common split — In many private companies, “Class A” is reserved for preferred stock issued to investors (with liquidation preferences, anti-dilution, and protective provisions), while “Class B” is the common stock held by founders and employees. This conflates the dual-class label with the preferred-vs-common question — see convertible preferred stock for what really matters in this version.
• Founder common with sub-classes — Some pre-IPO companies issue Class A founder common (super-voting) and Class B common (single vote) so the high-vote shares are pre-baked into the cap table years before the public offering. Meta, Snap, and Lyft all entered their IPO process with structures that already split common stock this way.

The practical upshot: in a private company, asking “what’s the difference between Class A and Class B?” is the wrong question. Read the certificate of incorporation. The voting ratios, conversion triggers, and dividend rights are written there explicitly, and the labels alone don’t tell you which class controls anything.

”Class B shares” in a UK limited company (alphabet shares)

The phrase “Class B shares” means something different in the UK and most Commonwealth jurisdictions. UK private limited companies routinely issue alphabet shares — Class A, B, C, and beyond — primarily as a tax-planning tool rather than a voting-control mechanism.

A small UK consultancy might issue Class A shares to one founder, Class B to another, and Class C to a spouse, with each class entitled to receive different dividends in different years. That lets the company declare, say, a £30,000 dividend on Class A in one year and £30,000 on Class C the next, optimizing each shareholder’s personal tax position. Voting rights may be identical, or differ slightly — the differentiation is usually about dividend flexibility, not control.

This has nothing to do with the US dual-class IPO structure. If you’re researching UK alphabet shares, look at HMRC guidance on settlements legislation (the “spouse share” anti-avoidance rules) and the Arctic Systems case — the policy area is meaningfully different from US founder-control questions.

What is Class B stock?

A short definitional answer for anyone landing here from search: Class B stock is a category of a company’s stock that’s distinct from Class A. The differences are defined in the company’s charter and typically cover voting power, dividend rights, conversion rights, and transfer restrictions. There’s no universal definition — every company can structure its share classes differently, and the labels carry no inherent meaning until you read the certificate of incorporation.

In the most common public-market pattern (Meta, Alphabet, Snap), Class B is the founder/insider class with higher voting power and trading restrictions. In Berkshire Hathaway’s structure, Class B is the lower-priced retail class with reduced voting power but accessible price. In a UK limited company, Class B is just a separately-defined dividend pool.

What it means if you’re a Class A shareholder

You get the economics — dividends, liquidation rights, share-price upside — and very little of the governance. Practically, that means:

• You can’t remove underperforming directors. Class B controls director elections.
• You can’t block a merger or charter amendment. Your vote is symbolic on transactions where Class B holds the majority.
• You still have fiduciary-duty protection. Directors owe duties to all shareholders, and breach-of-duty lawsuits remain available, though expensive.
• You can usually count on equal dividends. Most dual-class tech companies pay identical per-share dividends across classes.
• You may face an automatic conversion of Class B to Class A if a sunset clause triggers — usually a positive for governance.

Major asset managers — including Vanguard and BlackRock — now favor sunset provisions of 7–10 years, and FTSE Russell and S&P excluded several dual-class structures from key indices after 2017. That institutional pressure is why post-2019 IPOs increasingly include time- or event-based sunsets. Airbnb’s 2020 IPO, for example, includes provisions that convert Class B if CEO Brian Chesky departs or after a defined period.

When you’re modeling exit proceeds in companies that have layered preferred stock on top of a dual-class common-stock structure, the order of operations matters. Class B vs Class A is a voting question; preferred-stock liquidation preferences determine who actually gets paid first in an exit. The two structures coexist — see waterfall analysis and cap table modeling for how the math compounds — and you need both lenses to evaluate dual-class companies properly. Index-fund holders should also check whether the company’s convertible preferred stock layers add further complexity.

Frequently Asked Questions

What’s the main difference between Class A and Class B shares?

Voting power per share. Class B typically carries 10 votes; Class A carries 1. Economics — dividends, liquidation rights — are usually identical.

Can Class A shareholders convert to Class B?

No. Conversion runs only one way: Class B to Class A, usually triggered by sale to a non-affiliate or a sunset clause. Public investors can’t accumulate high-vote shares.

Do both classes get the same dividends?

In most dual-class tech companies, yes. The differentiation lives in voting, not cash flow. A handful of media companies have used dividend differentials historically.

Why aren’t Class B shares publicly traded?

To preserve founder control. Most charters auto-convert Class B to Class A on transfer to non-affiliates, which means the high-vote stock can’t migrate to outside investors.

Are dual-class structures legal?

Yes, in the US and most major markets. NYSE and NASDAQ permit them. Some indices (FTSE Russell variants) exclude dual-class companies, and institutional pressure has made sunset provisions standard in post-2019 IPOs.

How long do dual-class structures last?

Older structures were perpetual. Modern ones increasingly include 7–10-year sunsets or trigger conversion when the founder departs.

What’s the difference between Class A and Class B shares in a private company?

Usually that Class A is founder common with super-voting rights (often 10:1) and Class B is the lower-vote common held by employees and angels — the inverse of the public-market pattern. In some private companies, “Class A” is the label for investor preferred stock and “Class B” is founder/employee common. Read the certificate of incorporation; the labels alone don’t tell you which class controls the company.

What are Class B shares in a limited company?

In a UK or Commonwealth private limited company, Class B shares are typically part of an alphabet-share structure — multiple classes used to allocate dividends flexibly across shareholders for tax planning. Voting rights may match across classes; the differentiation is in dividend rights. This is a different concept from US dual-class structures, which centre on voting control rather than dividend allocation.

What is Class B common stock?

Class B common stock is one of two (or more) categories of common shares a company has authorized. The differences are defined in the company’s charter. In US dual-class IPOs, Class B common usually carries higher voting power (e.g. 10 votes per share), is held by founders and insiders, and converts 1:1 to Class A on transfer. The economics — dividends and liquidation rights — typically match Class A.

What is the difference between Class A and Class B shares vs Class C?

In a three-class structure (Alphabet is the canonical example), Class A is the publicly-traded class with one vote, Class B is the founder class with ten votes (not publicly traded), and Class C is publicly traded with zero votes. Class C lets the company issue stock for acquisitions and employee compensation without diluting founder voting power. The economics are equal across all three classes; only voting differs.

Are Class B shares better than Class A shares?

Neither is “better” — they’re different. Class B usually carries more voting power, but in most public dual-class companies it’s not available to outside investors. Class A is what you actually buy on an exchange, with full economic rights but limited governance influence. Whether that trade-off is acceptable depends on your view of the founders running the company.
