How much equity a management buyout needs

How much equity a management buyout needs. What the team puts in, and where the rest of the price comes from.

In short

A borrower-side guide to how much of their own money a management team puts into a UK lower-mid-market buyout or buy-in. The equity a deal needs is the residual: the price and the costs of completing, less the debt the business can prudently carry and the vendor paper the seller will leave in. The team fills it with its own money or brings in an equity partner, who then funds the residual while each manager's cheque is agreed person by person. Lenders look at the equity and vendor paper together as a cushion against the price, and at each manager's cheque against what that manager is worth. A buy-in asks more of its team than a buyout of the same company, because a lender lends less against the same earnings to an outside team.

Few management teams can fund the price of a business themselves, so the first question is how much of their own money the deal will take; buyers coming from outside often call it the deposit. The equity a deal needs is the price and the costs of completing, less the debt the company can prudently carry and the vendor paper the seller will leave in. The team fills that gap with its own money or a partner’s. The calculator in section 03 works it through on your own numbers.

Written for the management team’s side of the table. This is general guidance, not advice on your transaction. The rest of the stack is in our guides to financing a management buyout and financing a management buy-in.

How do you work out how much equity a buyout needs?

Price and costs, less the prudent debt and the vendor paper.

The funding requirement is the agreed price, any of the company’s existing borrowing the price does not already cover (change-of-control clauses make it repayable at completion), the costs of completing, and any cash the business needs to trade from the first day. The senior or unitranche debt the company can prudently carry comes off it, and so does the vendor paper the seller leaves in. What is left is the equity gap. Take a company earning £2m of EBITDA, with no borrowing of its own, sold for £10m with £2m left in as vendor loan notes. Bought by its own management, it carries senior debt at 3 times EBITDA; bought by an outside team, a bank underwrites toward the lower end of its 2.5 to 3.5 times range, say 2.5 times.

Illustrative: £2m of EBITDA, a £10m price and £2m of vendor loan notes, before costs. Only the senior multiple changes.

On these numbers the half turn the bank takes off for the outside team, £1m, passes directly to the buyers, whose equity gap is half as large again. Every pound the lender will not advance has to be found as if the price had risen by the same amount, which is why a team should know what the business can prudently carry before it agrees a price. A gap of £2m to £3m is more than most management teams can fund alone at this size, so in practice the seller leaves more in or an equity partner takes part of it, as section 05 sets out.

A unitranche fund will stretch to 4 to 4.5 times EBITDA, occasionally to about 5 for a strong sponsor-backed credit, and each extra turn comes off the gap until the lender’s own floor stops it. Lenders want a minimum of equity and subordinated paper beneath their debt as a share of the price: at 4 times, the example’s £8m of debt plus the vendor notes would fund the whole price and leave the buyers nothing at risk, which no lender will accept. Size the debt on the downside case, with covenant headroom of at least 25 to 30% against the base case, and let the equity be whatever that leaves. An asset-rich target can sometimes carry more through asset-based lending, and our guide to how much your business can borrow sets out what a business should carry.

How much equity would your deal need?

Put in your own price, earnings and vendor paper.

The calculator starts from the example above. Choose who is buying to set the senior multiple, or type your own, and it adds stamp duty on the price and the lender’s arrangement fee on the debt.

How much do lenders expect the management team to put in?

Lenders judge the cushion against the price and each cheque against the manager’s means.

The whole cushion beneath the debt, the equity and the seller’s subordinated paper together, matters as a share of the price, because it absorbs a fall in the company’s value before the debt is at risk. Each manager’s own cheque is judged differently, against what that manager is worth: a credit officer wants the people running the business to stand to lose something that matters to them. A cheque that looks small against a £10m price can be most of a manager’s liquid wealth, and a lender reads it that way. An outside team is asked for more, both because a lender gears a buy-in more conservatively and because its own capital at risk is one of the few signs the lender can test that the buyers believe in their plan, as our guide to financing a management buy-in explains.

Most lenders accept money a manager has borrowed personally, and check that the salary in the plan covers the repayments without pressure for dividends the facility agreement will restrict. The equity is a condition of the lender’s first drawdown, so any personal borrowing has to be in place before completion. Where a manager’s contribution is secured on the family home and the bank also wants a guarantee backed by a charge over property, the same house stands behind the deal twice, which is a strong case for capping the guarantee and carving the home out, as our guide to personal guarantees works through.

Where does the management equity come from?

The team’s own money, the seller’s, or a partner’s.

Personal borrowingA loan the manager takes, often against the homeA personal debt serviced from salaryMost lenders accept it, and check the salary in the plan covers it

More vendor notesThe seller leaves more of the price in as debtInterest, and a repayment at the endSubordinated paper, treated much like equity

Personal borrowing is a personal decision that needs its own independent advice, and the risk is plain. If the business fails, the equity is lost and the personal debt remains. A manager who borrows to buy into a company that is itself carrying acquisition debt has geared twice, and should size the borrowing on the assumption that the household may have to carry it with no value left in the shares.

More vendor notes enlarge the deduction in the arithmetic; a rollover is equity that fills the gap beside the team’s money. The terms worth negotiating on the notes are in our guide to vendor loan notes, and whether an equity partner is worth the ownership it takes is the subject of our guide to debt versus equity.

How does sweet equity work when private equity backs the team?

Most of the investor’s money ranks ahead of the ordinary shares the team buys.

When a private-equity house backs a management team, most of the house’s money goes in as loan notes or preference shares, which carry a fixed return and rank ahead of the ordinary shares, and a small slice goes into ordinary shares. That package is often called the institutional strip. The managers subscribe for ordinary shares alongside it, so a small cheque buys a much larger share of the ordinary equity than of the money put in. That disproportion is what the market calls sweet equity.

£0.10m of £0.35m subscribed for ordinary shares

Managers 29%

Illustrative: an investor puts in £5.0m, £4.75m of it as loan notes or preference shares and £0.25m as ordinary shares, and the managers put in £0.10m, all in ordinary shares. The split is negotiated on every deal.

On a sponsored deal the investor funds whatever the debt and the vendor paper leave, so the team’s cheque is no longer the residual worked out above. Investors want hurt money from each manager, a sum that matters to that person, commonly framed against salary; a manager who already holds shares or is receiving part of the sale proceeds should expect to put some of that value back in.

The ordinary shares are the most exposed layer in the structure, and the shareholders’ agreement’s leaver terms decide how much of a departing manager’s cheque comes back. A senior lender treats the institution’s loan notes much as it treats equity, provided the intercreditor subordinates them, their interest rolls up while the senior debt is outstanding, and they mature after it. The tax treatment of management shares needs specialist advice from the first draft of the structure.

What costs does the equity have to cover?

The costs of completing add to the gap the equity fills.

The lender charges an arrangement fee, nearer 1% of the facility on a bank deal and more from a fund. The buying company pays its own lawyers, the lender’s lawyers under the facility agreement, the team’s corporate-finance and debt advisers, and the diligence the lender relies on; VAT on those fees may not be recoverable by a newly formed buying company. It also pays stamp duty on the shares, 0.5% on a stock transfer form, rounded up to the nearest £5. GOV.UK, Stamp Duty on a stock transfer form. The duty runs on the whole consideration, including any part paid in loan notes or shares, so on the example it is £50,000 on the full £10m. HMRC, Stamp Taxes on Shares Manual STSM021060.

The debt is sized off earnings, so it does not grow to meet the bill, and these costs fall on the equity unless the seller leaves more in or the company’s surplus cash at completion meets part of them. If the deal aborts, the costs so far fall on the buyers. The revolving facility cannot be counted on to fund the price either: facility agreements commonly confine it to working capital or cap what may be drawn at completion. The lender’s fees are set out in full in our guide to the all-in cost of raising debt.

How does the cheque differ between an MBO, an MBI and a BIMBO?

The structure changes who can contribute, and in what form.

An incumbent who already owns shares can often contribute some of them in place of cash, subject to the tax advice that step needs, while incoming managers on a buy-in start from cash and face the larger gap in Fig. 01. A BIMBO combines the two. Incoming managers buy in alongside insiders who stay, the continuity lets a lender gear more comfortably than for a pure buy-in, and the equity is shared between the two groups. Who puts in what, and what happens to a manager’s shares if they leave, then becomes a negotiation among the buyers as well; settle those terms in the shareholders’ agreement before completion.

Where to start

We will tell you how big the cheque has to be before you agree a price.

If you are working out how much of your own money a buyout or buy-in will take, the useful first conversation is how much debt the business can prudently carry, and therefore how large the equity has to be, before anyone agrees a price. It is confidential and costs nothing. We run the whole market against itself, bank and fund, and will say plainly where the prudent debt leaves a gap the team cannot fill alone, and whether the answer is more vendor paper, an equity partner, a lower price or a different shape of deal. A clean raise runs twelve to sixteen weeks from mandate to money, and the cheque is easiest to shape at the start of it. See how a mandate runs in how we work, or the full range of what we advise on in our services.

The terms in this guide

Each is defined in full in the library, with the levels and conventions that apply at £3-15m.

  • Leverage covenant

    A leverage covenant caps your debt as a multiple of EBITDA, tested every quarter. It is rarely one number and rarely one measure: most facilities test several, on a schedule that tightens each year.

  • Management buyout (MBO)

    A management buyout is the team that runs a business buying it. The funding is a stack of senior debt, vendor paper and the team's own equity, and the hardest decision is taking less debt than the market will offer.

  • Mezzanine

    Mezzanine is a loan sitting behind the senior facility, secured and dated, usually part cash-pay and part PIK. It buys quantum the senior lender will not stretch to, and it adds a creditor, a maturity and an intercreditor.

  • Normalised EBITDA

    Normalised EBITDA is your statutory earnings adjusted for things that will not recur. It is the number your facility is sized on, and every adjustment in it is tested on its own.

  • Preferred equity

    Preferred equity is a class of shares ranking ahead of the ordinary shareholders and behind every creditor, with a fixed return that accrues to exit rather than being paid in cash. It costs more than mezzanine and forgives more.

  • Sponsor

    A sponsor is the private equity firm backing the equity in a transaction. Its presence changes the debt available, because a lender is underwriting a fund that can write a second cheque as well as a business.
