Share Buyback Agreements For Founder Exits

Priya and Dan started a software company together three years ago. Priya now wants to step away, but she still owns 30% of the shares. Dan wants the company to buy those shares back so the cap table is clean before the next funding round.

That sounds simple enough. Agree a price, pay Priya, cancel the shares and move on. But in the UK, a company buyback of founder shares has a very specific Companies Act 2006 process, and getting the paperwork wrong can leave the buyback invalid.

The good news is that a founder exit share buyback can be a very tidy way to handle a departure, as long as you deal with both sides of the transaction: the commercial negotiation with the leaving founder and the company law steps that make the buyback effective.

Can Your Company Buy Back A Departing Founder's Shares?

Yes, a UK private limited company can usually buy back a departing founder's shares if its articles allow it, the shares are fully paid and the company follows the Companies Act 2006 rules.

A buyback is different from one shareholder buying another shareholder's shares personally. With a buyback, the company itself buys the shares. The shares are then usually cancelled, which means the remaining shareholders' percentage ownership increases.

For example, say your company has 100 ordinary shares. You own 60 and your co-founder owns 40. If the company buys back and cancels your co-founder's 40 shares, there are 60 shares left in issue and you own 100% of them.

Before you go too far, check:

• The articles of association, to see whether buybacks are permitted or restricted.
• Your shareholders agreement, especially leaver provisions, compulsory transfer rules, valuation methods and investor consent rights.
• The share class rights, as some share classes have special rights that affect exits.
• Whether the shares are fully paid, because a company can only buy back fully paid shares.
• Whether you have enough distributable profits or another lawful funding route, because the company can't simply pay whatever price you agree if the Companies Act rules aren't met.

If your articles or shareholders agreement already include a clear leaver mechanism, that may shape the whole negotiation. If they don't, you'll need to agree the terms directly with the departing founder and document them properly.

Is A Founder Exit Share Buyback The Right Option?

It depends, because a buyback is helpful when you want the company to take the shares off the table, but it isn't always the simplest or cheapest route.

A share buyback can work well where:

• You want to remove the departing founder from the cap table before investment or sale discussions.
• The remaining founders don't want to use personal funds to buy the shares.
• The company has distributable profits or another lawful way to fund the purchase.
• You want the shares cancelled rather than transferred to another person.
• The departing founder wants a clean exit and is willing to sign wider exit documents.

Other options may be better if the company can't fund the buyback or if investors prefer a share transfer. For example, the remaining founders might buy the shares personally, an incoming investor might buy them under a share purchase agreement, or the founder might keep some shares as a passive shareholder.

The commercial point matters as much as the legal structure. If your departing founder is still involved in customer relationships, product knowledge or investor conversations, you may want a broader exit package that covers handover, confidentiality, intellectual property, resignation and public messaging.

What Should A Share Buyback Agreement Cover?

A share buyback agreement should set out the exact terms on which the company buys the founder's shares, including the price, timing, approvals and what happens if the legal steps aren't completed.

For an off-market share buyback by a private company, this agreement is often called the buyback contract or off-market purchase contract. It isn't just a receipt. It's the contract shareholders approve under the Companies Act 2006.

Your agreement will usually cover:

• The shares being bought back, including the number, class and share numbers if relevant.
• The purchase price, including how it was calculated and whether it includes any discount under share vesting or leaver provisions.
• Payment terms, such as one lump sum, staged payments or completion accounts.
• Completion mechanics, including when the shares are delivered to the company and when payment is made.
• Conditions, such as shareholder approval, investor consent, director approval and evidence of distributable profits.
• Founder warranties, such as confirmation that the founder owns the shares and hasn't charged or transferred them.
• Tax and stamp duty mechanics, including who handles the SH03 process and payment of any stamp duty.
• Confidentiality, especially around the exit terms and company information.
• Consequences if the buyback can't proceed, including whether the agreement falls away or converts into another exit route.

Templates often miss the practical parts that matter in a founder exit, such as staged payment protections, leaver provisions and what happens to directorships or employee rights. A buyback document works best when it matches your company's articles, shareholders agreement and funding position.

What Is The Legal Process For An Off-Market Share Buyback?

An off-market share buyback for a private company must follow the Companies Act 2006 process, including approval of the buyback contract and Companies House filings.

Most founder exits in private companies are off-market buybacks, because the shares aren't traded on a public market. The process can vary depending on how the buyback is funded, but a typical buyback out of distributable profits looks like this.

Step 1: Check The Rules And Funding

First, check the articles, shareholders agreement, investor consents and share terms. You also need to confirm that the company has enough distributable profits if it's paying from profits.

Your accountant will usually help confirm distributable profits. Cash in the bank isn't the same thing. A company may have cash but not enough distributable reserves for a lawful buyback.

Step 2: Agree The Buyback Contract

Next, agree the off-market purchase contract with the departing founder. This should be in writing and should usually be conditional on shareholder approval, so you don't accidentally sign an agreement that the company can't lawfully perform.

Step 3: Get Shareholder Approval

The buyback contract must be approved by an ordinary resolution of shareholders, which usually means more than 50% of the votes cast. The selling founder's votes generally can't be counted in favour of the resolution for their own shares.

If you approve the buyback at a meeting, a copy of the contract or a memorandum of its terms must be available for inspection by shareholders for at least 15 days before the meeting and at the meeting itself. If you use a written resolution, the contract or memorandum should be sent or submitted to eligible shareholders at or before the resolution is circulated.

Your shareholders agreement may require a higher approval threshold, investor consent or board consent as well.

Step 4: Complete The Buyback

Once approvals are in place, the company completes the buyback by paying the price and receiving the shares. The exact completion steps should match the agreement.

After completion, the shares are usually cancelled. In some cases, a company can hold shares in treasury, but for many founder exits cancellation is cleaner and easier to explain to future investors.

Step 5: Make The Filings And Update Registers

You then need to deal with the company records and Companies House filings. For a buyback, this usually includes:

• Form SH03, the return of purchase of own shares, which should be filed with Companies House within 28 days of the shares being delivered to the company.
• Stamp duty, usually at 0.5% of the consideration, rounded up to the nearest £5, where the consideration is more than £1,000. HMRC stamping is generally needed before Companies House will accept the SH03.
• Form SH06, if the shares are cancelled, which should usually be filed within 28 days beginning with the date the shares are delivered to the company.
• The register of members, which should be updated to show the cancellation or change in shareholding.
• The PSC register and Companies House PSC records, if the change affects who has significant control over the company.

You should also keep a copy of the buyback contract or memorandum available for inspection as required by the Companies Act 2006. Company records matter here because future investors, buyers and due diligence teams will often ask to see the buyback paperwork.

How Do You Pay For A Company Buyback Of Founder Shares?

You can only pay for a share buyback using a lawful funding method, and the most common route for a private company is payment out of distributable profits.

The main funding options are:

• Distributable profits, which is usually the simplest route if the company has enough reserves.
• Proceeds of a fresh issue of shares, where the company issues new shares and uses the proceeds to fund the buyback.
• Payment out of capital, which has stricter solvency, approval and notice requirements.
• The small cash de minimis route, which may allow a private company to fund a limited buyback out of capital up to the lower of £15,000 or 5% of the nominal value of fully paid share capital in a financial year, if the conditions are met.

A buyback out of capital needs extra care. It can involve a directors' solvency statement, an auditor's report, a special resolution, Companies House filings, Gazette notice and a creditor objection period. Timing is also more involved, because payment out of capital generally can't be made immediately after the resolution.

If you want to pay the leaving founder over time, check the structure carefully. The Companies Act rules can affect when the purchase is treated as made and whether the company can lawfully defer payment. A badly structured instalment arrangement can create problems if the company later lacks reserves or if the founder argues they still hold rights until paid in full.

What Other Founder Exit Documents Do You Need?

You'll often need more than a share buyback agreement, because the share exit is only one part of the founder relationship.

Depending on the circumstances, your exit documents may include:

• Board minutes approving the proposed buyback, calling the shareholder meeting or approving written resolutions.
• Shareholder resolutions approving the buyback contract and any related matters.
• A deed of release, covering agreed claims between the company and the departing founder.
• A director resignation letter, if the founder is stepping down as a director.
• An employment settlement agreement, if the founder is also an employee and you want a valid waiver of statutory employment claims. Under UK employment law, this usually requires the employee to receive independent legal advice.
• IP assignment documents, if any intellectual property was created outside employment or before the company was set up.
• Confidentiality and non-disparagement terms, to protect sensitive company information and manage the exit message.
• Restrictive covenants, such as non-solicitation or non-compete terms, if they're reasonable and properly drafted for your business.

Intellectual property is a common gap in founder exits. If your departing founder built the first version of your app before incorporation, designed your brand, wrote key code as a contractor or registered assets personally, the company may not own everything it thinks it owns. Sorting that before the founder leaves is far easier than trying to fix it during a funding round.

You should also think about practical handover. Access to source code, passwords, supplier contacts, domain names, social media accounts, pitch decks and customer records should all be dealt with before completion or as part of a short transition period.

Common Mistakes To Avoid

The biggest mistake is treating a founder share buyback like an ordinary share transfer. It's not. A company buying back its own shares has its own statutory process.

Watch out for these issues:

• Skipping shareholder approval, which can make the buyback invalid.
• Counting the selling founder's votes incorrectly, especially where they still control a large percentage of the company.
• Relying on cash in the bank instead of checking distributable profits, which can cause an unlawful distribution problem.
• Missing Companies House filings, including SH03 and SH06 where relevant.
• Forgetting stamp duty, particularly where the buyback price is more than £1,000.
• Leaving IP, confidentiality and handover issues until after completion, when you have less leverage.
• Using a generic agreement that doesn't match your articles, shareholders agreement or investor consent rights.
• Ignoring tax advice, because founder exits can have tax consequences for both the company and the departing founder.

There's also a relationship point. Founder exits can be emotional, especially if the business started as a friendship. Clear documents can lower the temperature because everyone can see the price, timing, conditions and next steps in writing.

Key Takeaways

• A share buyback agreement in the UK needs to work with the Companies Act 2006 process, not just record the price.
• For an off-market buyback, shareholders usually need to approve the buyback contract by ordinary resolution before completion.
• The selling founder's votes generally can't be counted in favour of approval for their own share buyback.
• You need a lawful funding route, usually distributable profits, proceeds of a fresh share issue or a carefully managed capital route.
• After completion, you'll usually need to file SH03 within 28 days, deal with stamp duty if payable and file SH06 within 28 days beginning with the date the shares are delivered if shares are cancelled.
• A founder exit should also cover resignation, IP, confidentiality, handover, employment issues and releases where relevant.
