Sell a Majority Stake and Stay Involved

What we do on a majority stake sale

Mergers.co.uk advises UK SME founders on selling a controlling stake, usually 51% to 80% of the equity, to a strategic trade partner, private equity firm or family office. You take a significant capital sum out of the business now, retain a minority stake, and continue running the business under an agreed governance framework.

We act only for founders. We never act for buyers, investors or incoming partners. The whole engagement is confidential, selective and focused on protecting your position, financially, operationally and personally, including how the deal is structured, not just what it is worth on paper.

Who this service is for

This is not a generic M&A service. It is built for a specific kind of founder:

• You run a profitable UK SME, broadly £2m to £25m turnover.
• You want significant cash out, but you are not ready to retire or walk away.
• You want to stay involved as managing director, CEO or executive chair after the deal.
• You want the right partner alongside you for the next phase, not just the highest bidder.
• You want an adviser whose loyalty is to you, not to the buyer.

Why founders choose this route

A majority stake sale lets you do three things that a clean full exit cannot. You take meaningful capital out of the business now, you stay involved in something you still believe in, and you keep skin in the game so you share in the next phase of value creation.

For the right founder and the right business, the combined return, first transaction plus the eventual second exit on the retained stake, can exceed what a single full sale would deliver today. That said, it is not automatically the better outcome; it depends on execution, the partner you choose and market conditions over the following years, which is why the sections below cover the mechanics and risks in detail rather than presenting this as a guaranteed win.

Governance and reserved matters

The percentage of equity you sell is only part of the story. What actually determines your influence after completion is the governance framework set out in the shareholder agreement, particularly the list of reserved matters.

Reserved matters are decisions that cannot be taken without the agreement of a specified group of shareholders, regardless of who holds a bare majority. In a well-negotiated majority sale, the founder secures reserved matter protection over decisions that materially affect their role, their retained equity value or the direction of the business: matters such as changes to the founder's role or remuneration, further share issues that would dilute the founder, disposal of material assets, changes to the business plan or budget, additional borrowing above an agreed threshold, and any sale of the whole company. Without these protections, a founder holding 20% or even 40% of the equity can find themselves with almost no formal say over decisions that directly affect the value of their retained stake.

Board composition matters just as much as reserved matters. Founders should expect to negotiate the number of board seats they retain, whether they keep the chair or a casting vote on any matters, and how board decisions are actually made in practice, not just on paper. It is common for a majority investor to want board control commensurate with their economic stake, but the specific balance is negotiable and should reflect the operational reality that the founder is often still running the business day to day.

Getting this framework right before signing is far more valuable than negotiating an extra percentage point on the headline price, because it is the governance terms, not the price, that determine your working life for the next several years.

Rollover equity mechanics

Rollover equity is the mechanism by which your retained stake is carried forward into the new ownership structure, rather than simply left as your original shares in the trading company.

Most majority deals, particularly those involving private equity, use a new holding company (often called Newco or Topco) set up specifically for the transaction. The incoming investor injects new capital into Newco, which acquires the trading company, and your rollover shares are exchanged for shares in Newco rather than being left in the original entity. This matters because the terms attached to the new capital, particularly any preference shares or loan notes the investor holds, sit ahead of ordinary equity in the event of a future sale or wind-down. A founder's rollover stake, even if it looks like a straightforward percentage on paper, can be worth materially less than expected if the investor's capital carries a preferred return that is paid out first.

Before agreeing to roll over equity, founders should understand exactly what class of share they are receiving, whether there is a liquidation preference or ratchet mechanism that adjusts returns based on performance, how any management incentive plan (often called a sweet equity or MIP arrangement) interacts with the rollover stake, and what happens to the rollover shares if the founder leaves the business before a second exit, whether through good leaver or bad leaver provisions. These details are technical, but they determine the real economic value of staying involved, and are worth as much scrutiny as the headline valuation.

For background on how retained equity is typically valued and protected, see our guide to minority stake protections and our explainer on rollover, control and minority positions.

Choosing the right partner

In a majority sale, you are choosing who you will work for, and with, for several years. That makes partner selection at least as important as price.

Useful diligence on a prospective majority partner includes speaking to founders of other businesses they have backed, understanding their typical holding period and exit strategy, clarifying how hands-on or hands-off they intend to be operationally, and being direct about how decisions get made when you disagree. It is also worth understanding their track record through a downturn or underperformance, since how a partner behaves when things are going well tells you far less than how they behave when they are not.

A partner offering a slightly lower headline price but a genuinely better governance framework, cultural fit and track record of supporting management teams is very often the better choice over a higher bidder who will be difficult to work alongside. This is a judgement call that benefits from an adviser who has seen how different buyer types behave post-completion, not just how they behave during negotiation.

Trade partner or private equity for a majority deal

The two most common types of majority buyer bring genuinely different things to the table, and the right choice depends on what you want from the next phase.

A trade buyer is typically a company operating in the same or an adjacent sector, looking for synergies, customer access, geographic reach or capability that complements its existing operations. A majority sale to a trade partner can bring immediate commercial benefits such as cross-selling, procurement savings and shared infrastructure, but it can also mean deeper integration into the buyer's existing business, less operational autonomy, and a partner whose own strategic priorities may shift over time and affect your business more directly than a financial investor's would.

Private equity firms are financial investors with a defined investment horizon, typically three to seven years, looking for a clear plan to grow enterprise value and exit profitably. They generally bring more capital for growth (acquisitions, new markets, senior hires), more formal governance and reporting discipline, and a structured route to a second exit, but they also expect a demonstrable growth plan, closer board involvement, and are focused on their own return timeline, which may not always align with the founder's personal preferences on pace or risk.

Neither option is inherently better. Founders who want deep sector synergy and are comfortable with more integration often prefer a trade partner. Founders who want capital, growth support and a defined path to a second exit, while keeping the business operationally independent, often prefer private equity. See our full comparison of trade sale versus private equity and growth partner versus cash investor for more detail.

Founder role and management expectations after completion

Staying on as MD or executive chair after a majority sale is not the same job you had as sole owner. Expectations, reporting lines and accountability all change.

Most majority investors expect a formal business plan and budget, regular management information (often monthly management accounts and KPI reporting rather than the more informal reporting many founder-led businesses are used to), and a board that meets on a structured schedule to review performance against plan. Founders who thrive in this environment typically welcome the added discipline and see it as a positive forcing function; founders who find it constraining should factor that honestly into the decision before signing, since it is a genuine change in day-to-day working life, not a minor administrative adjustment.

Remuneration, notice periods, non-compete and non-solicit restrictions, and the circumstances in which the founder could be removed from their role are all matters that should be negotiated and clearly documented in the service agreement and shareholder agreement at the time of the deal, not left for later discussion. A founder's rollover equity value can also be affected by whether they are a "good leaver" or "bad leaver" if they exit the role before a second sale, so these definitions deserve careful attention rather than being treated as legal boilerplate.

Second stage exit: how retained shares get valued

The commercial logic of a majority sale usually rests on a second exit some years later, when the whole business, including the founder's retained stake, is sold again at a higher valuation.

At that point, enterprise value is assessed in the same way as any sale: a multiple of maintainable earnings, adjusted for growth, scale, diversification and reduced key-person risk built up over the intervening years, less net debt, to arrive at equity value. That equity value is then split according to the capital structure agreed at the outset: any preference shares or loan notes held by the majority investor are typically paid out first (sometimes with an agreed preferred return on top of the original capital), and the founder's rollover stake receives its proportionate share of what remains, which may or may not have been diluted by further fundraising rounds in the interim.

This means a founder's eventual proceeds from a second exit depend on business growth, the specific preference and ratchet terms agreed at the first transaction, and any dilution along the way, not simply on the percentage originally retained. Modelling a realistic range of second-exit outcomes, under different growth and structuring scenarios, before agreeing to the first deal is one of the most valuable pieces of analysis an adviser can provide, and it is something we do as standard on every majority sale mandate. For more on the mechanics of a staged approach, see our guide to the two-stage exit strategy and valuation reality in partial sales.

Risks and disadvantages of a majority stake sale

This route has real benefits, but it is not without genuine downside, and founders should weigh both honestly before proceeding.

• You give up legal control, and even with strong reserved matters, some decisions will go the majority shareholder's way
• Working relationships can deteriorate if strategic priorities diverge from your partner's after completion
• Your retained stake can be diluted by later funding rounds if pre-emption rights are not properly protected
• A second exit is not guaranteed and may take longer, or achieve a lower valuation, than originally modelled
• Personal and professional identity can be harder to adjust to when you are no longer the final decision-maker in your own business
• Preference terms held by the investor can mean your retained equity is worth less than the headline percentage suggests

None of these risks make a majority sale the wrong choice for the right founder and the right business, but they are reasons to negotiate governance, rollover terms and leaver provisions carefully, and to choose a partner on more than price alone.

"What if I'm not sure I'm ready?"

Most founders we speak to are not ready to start a process the day they call. They are weighing it up. They want a confidential, off-the-record view from someone who is not trying to sell them a deal.

That is fine. The first conversation is exactly that, a private discussion, no paperwork, no commitment, no follow-up unless you want one. If a majority stake sale is not the right answer for you right now, whether a minority stake sale, a full exit, or simply waiting, we will tell you.
