A Shares vs B Shares: What UK Startups Need to Know About Share Classes

When you’re launching a new company or planning your first investment round, sooner or later you’ll stumble across conversations about “A Shares” and “B Shares” - and you’ll probably hear people mention “share classes” too. If you’re wondering: do these really matter for my startup? The short answer is yes.

Getting your share structure right from day one is essential if you want to attract investment, protect founder control, and avoid future headaches. But the whole world of A shares, B shares, voting rights, and dividends can quickly get overwhelming - especially if you’re new to the game.

Don’t stress. In this guide, we’ll walk you through the essentials of A and B shares for UK startups. You’ll learn:

• What "A" and "B" shares actually mean
• How different share classes impact control and ownership
• When and why you might issue B shares (and the pitfalls to watch for)
• How to set things up safely from the start - so your business is protected as it grows

What Are A Shares and B Shares?

Let’s start with the basics: every UK company is owned by its shareholders, and those shareholders hold "shares" that represent their slice of the business. But not all shares are created equal. A company can have different “classes” of shares, and each class can come with different rights - covering things like:

• How much say you get in decisions (voting rights)
• How dividends are paid out
• What happens if the company gets sold or wound up

“A Shares” and “B Shares” are just labels to show which set of rights a share has. You could have other classes too (like “C Shares” for employees), but A and B are the most common for startups.

Here’s a quick overview:

• A Shares: Typically the "standard" share with full voting rights, right to dividends, and a share in sale proceeds.
• B Shares: Often structured to have fewer voting rights (or none), sometimes no right to dividends for a period, or other limitations compared to A shares. They're often used for founders, employees, or non-controlling investors.

But remember - the exact rights of each class must be spelled out in the company’s articles of association or a shareholders’ agreement. If you don’t set this up carefully, disputes (and expensive legal battles) can arise later.

Why Do Startups Use Different Share Classes?

Most startups begin with just one class of ordinary shares (usually A shares). As you grow, you may hit scenarios where different share classes really help:

• Keeping founder control - You might give investors B shares with limited voting rights, so you and your co-founders retain decision-making power.
• Employee share incentive schemes - You could issue B shares to your early hires, sometimes structured so they don’t get dividends until the company exits or hits a target.
• Attracting investors without giving up too much - You may offer B shares with fewer voting rights to angel investors who want to support you but don’t need a say in day-to-day decisions.
• Rewarding or protecting key contributors - For example, advisors or consultants might get non-voting B shares as a reward without giving them control.

Different share classes are a way to tailor ownership and control for your specific growth plans. But be careful: setting up confusing or unfair classes can scare off future investors - or lead to disputes within your founding team.

What Rights Can A and B Shares Have?

The beauty (and the risk) of the UK system is you can design share rights how you like - as long as they’re clear in your legal documents. Here are some of the key rights you might attach to A or B shares:

• Voting rights: Most A shares carry one vote per share at company meetings. B shares might have
• No votes at all,
• One vote per share (just like A shares),
• Or limited voting on certain matters only (e.g. not on appointing directors).
• Dividend rights: You can decide whether B shares get the same, less, or delayed dividends compared to A shares.
• Rights on sale or liquidation: Some B shares only pay out if the company gets sold or liquidated (common for employee incentive shares).
• Convertible or redeemable features: B shares might be structured so they “convert” into A shares after meeting certain milestones (useful for vesting arrangements and employee incentives).

Top tip: Get clear legal advice before you set any of this up. A professionally drafted shareholder agreement can prevent chaos if someone wants to leave, you bring in new investors, or there’s a dispute.

What Are the Pros and Cons of Issuing B Shares?

Every startup is different - so there’s no “one size fits all” answer here. But here’s a quick breakdown of why you might use B shares, and the risks to watch for:

Benefits of B Shares

• Attracting investment without losing control: Ideal if you want to raise money, but don’t want new investors having a say in every business decision.
• Employee incentives: B shares are often used in EMI share option schemes, letting employees share in success without diluting founder authority.
• Flexibility for founder exits: You can set it up so that if a founder leaves early, their B shares convert to a different category or lose value, protecting those who stay.
• Rewarding other contributors: Useful for giving a slice of the business to advisors or consultants, without them interfering in company strategy.

Potential Drawbacks

• Investor concerns: Some sophisticated investors are wary of B shares, especially if rights aren’t clear or seem unfair.
• Complexity for future funding rounds: Multiple share classes can complicate later investments - future investors may demand all shares have the same rights and force you to “clean up” your structure.
• Risk of disputes: If it’s not 100% clear what B shareholders can and can’t do, disputes or legal action could arise down the line.
• Administration hassle: Keeping track of who owns what, and running company votes, gets more complex with different share classes - especially if you’re not using online cap table software.

The bottom line? B shares can be a powerful tool, but only if you’re clear and upfront about the rights attached, and protect yourself with clear agreements.

How Do You Create A and B Shares Legally?

You can only create new share classes, or attach special rights to shares, if your company documents allow it. Here’s how to do it right:

1. Check or Amend Your Articles of Association

Your articles of association set out the rules for shares in your company. If you want B shares with different rights, your articles need to allow for them - or you must update them (via a special shareholders’ resolution).

2. Issue New Shares and Update Your Share Register

Once your articles are set, you’ll need to issue new shares or reclassify existing shares as A or B, making sure the company’s register and Companies House filings are all up to date.

3. Document everything in a Shareholders’ Agreement

Don’t rely on a handshake. A substantial shareholders’ agreement is a must - spelling out what votes are needed for decisions, how exits work, what happens if someone wants to sell, and how disputes are resolved.

Remember: Standard templates rarely cover all the nuances of b à. Get tailored legal advice to ensure everyone’s rights (and your company’s future) are fully protected.

What Else Should Startups Know About Share Classes?

When setting up b à or any other share classes, bear in mind:

• Tax implications: The way you set up share rights (especially for employee schemes) can have major tax effects. For example, EMI share options can offer tax advantages, but only if the structure is right from the beginning.
• Investor expectations: Some investors will insist on “pari passu” rights (equal rights for all shares). Be clear on your objectives and future fundraising plans before locking in share classes.
• Founders’ relationship: Misalignments in voting or dividend rights can cause friction amongst founders - clear early conversations and written agreements help avoid painful fallout later.
• Statutory protections: Even B shareholders with limited rights benefit from basic legal protections under the UK Companies Act 2006 (like unfair prejudice provisions).

If you’re unsure about any of the legal stuff, or how b à might impact your business, it’s always smart to chat to a startup lawyer early on. Getting this right now will save you a lot of drama in the future - especially as your company grows, or if you want to attract investment or sell.

What Legal Documents Will I Need?

If you’re creating b à for your UK company, make sure you’ve got these essentials in place:

• Updated articles of association specifying all share classes and detailed rights.
• Shareholders’ agreement covering shareholder rights, voting powers, sale/exit rules, founder leaver provisions and more.
• Share certificates and a share register up to date with all new share classes and holders.
• Option agreements (if offering shares to employees/advisors) with clear vesting and conversion terms.
• Companies House filings to show every new share issue/classification on the public record.

Don’t DIY your documents - it’s essential to get them properly drafted and reviewed by an expert to make sure they actually do what you want them to, and can stand up if there’s a dispute. Templates miss the specifics that can make or break your business relationship down the line.

Key Takeaways

• “A” and “B” shares (also known as share classes) let you tailor ownership, voting, and dividend rights to suit your startup’s strategy.
• B shares are often used to give employees, advisors, or minority investors a stake - while keeping founder control intact.
• The rights attached to each share class can vary - but must be set out clearly in your articles of association and shareholders’ agreement for legal certainty.
• Watch out for the pitfalls: unclear rights, mismatched shareholder expectations, tax issues, and increased admin can all cause future disputes.
• You should always have properly drafted legal documents in place - especially articles, shareholders’ agreement and share/option certificates - when creating or issuing b à.
• Getting legal advice early is crucial to protect your business from day one and make your company attractive for future investment and growth.
