Financing a management buyout. The debt structure, the equity gap, and the terms that matter.
In short
A UK lower-mid-market management buyout is funded from four sources: senior or unitranche debt sized off the company's EBITDA, vendor paper the seller leaves in behind the senior lender, the team's own money and, where a gap remains, an equity partner. A bank lends roughly 2.5 to 3.5 times EBITDA on senior cash-flow terms and a unitranche fund 4 to 4.5 times, but a team with one balance sheet should size the debt on a downside case, well inside what the market will lend. The covenant package, personal guarantees and leakage controls matter more than half a point on the margin.

The order of assembly matters most. Size the debt on the case where a bad year arrives and let the vendor paper, the team’s money and any partner fill what is left, because a team funding its own buyout usually cannot write a bigger cheque when a covenant resets. Over-gear at completion and a business that looked fundable in a good year runs out of headroom in an ordinary soft one.
Written for the buying team’s side of the table. This is general guidance on raising the debt, not advice on your transaction, and it deepens the shorter answer in our guide to raising debt. Valuation, the sale agreement and the tax structuring belong to your corporate-finance lead, lawyers and accountants; we run the debt.
Debt, vendor paper, management money, and sometimes a partner.
Debt funds most of the price and ranks first. A bank term loan or a unitranche from a direct-lending fund is sized off the company’s cash flow, secured by a debenture and repaid ahead of everything below it, and it is the cheapest money in the structure. Direct lenders put much of their capital into acquisitions: on the Deloitte tracker about two-thirds of European private-debt activity funds an acquisition rather than a refinancing or growth.

Vendor paper sits next: deferred consideration and vendor loan notes, paid to the seller later and subordinated to the senior lender. Then comes the team’s own contribution, meaningful against their means and modest against the price. Where a real gap remains, an equity partner takes a minority or majority stake, with the managers rolling or subscribing for equity alongside it on terms the tax and legal workstreams settle.
Senior debt is repaid first, vendor paper costs least in cash terms but is deeply subordinated, and the managers’ money and any outside equity cost the most and rank last, so the plan uses as little of them as it safely can. Fig. 01 in section 04 draws that ranking for an illustrative £10m buyout.
Size on the bad year, not the good one.
What the market will lend and what the business can safely carry are two different numbers. On senior cash-flow terms a bank will typically lend around 2.5 to 3.5 times EBITDA to a decent lower-mid-market company; a unitranche fund will usually stretch to 4 to 4.5 times, occasionally to five for a strong, sponsor-backed credit with recurring revenue. The amount to take is set by serviceability on a downside, where a customer leaves and margin compresses, and by cash conversion: a business that turns most of its EBITDA into cash carries debt a capital-hungry one cannot at the same leverage.
The discipline bites harder on an MBO. A private-equity sponsor borrows to the ceiling because the equity maths rewards it and its fund can inject capital if a covenant tightens; a management team has one balance sheet and no easy second cheque, so the prudent amount sits well inside capacity.
Gearing the completion structure so tightly that the business cannot absorb its first setback is the failure to avoid, and our short answer on how much leverage to raise and how much to take sets out the judgement. Whatever the debt cannot prudently cover, the vendor, the team and any equity partner have to fill.
Your numbers
Work the gap through on your own price, earnings and vendor paper with the equity calculator in our guide to how much equity a management buyout needs.
Paper the seller leaves in, ranked behind the bank.
Almost every lower-mid-market MBO carries some vendor paper, because prudently sized senior debt and a modest team cheque rarely reach the price, and deferred consideration bridges the gap without diluting the managers. The senior lender accepts it only if the paper sits out of its way: repayment blocked, or confined to an agreed schedule, while the senior debt is outstanding; no enforcement by the seller without the lender’s consent; and interest usually rolled up instead of paid in cash. The intercreditor agreement, or a subordination deed, records that ranking before the lender funds, and the figure shows who is repaid first.
Who is repaid first, on an illustrative £10m buyout.
Rank 1: Senior debt£6.0m
Secured on the group and guaranteed by the trading company. Repaid first.
Rank 2: The trading company’s other creditors
Suppliers, landlords and HMRC. Owed by the business itself, so ahead of anything owed by the holding company.
Rank 3: Vendor loan notes£2.0m
Owed by the holding company and subordinated by deed. Paid only when the senior lender allows.
Rank 4: Equity£2.0m
The team’s money. Paid last, and takes whatever value is left.

Ranked that way, the paper stretches what the deal can fund without competing with debt service while the senior debt amortises. It is still a real claim, repaid once the senior lender is cleared, so size it against the same downside case as everything else.
Lenders also read the seller’s appetite for paper as a signal. A seller who leaves meaningful consideration in, subordinated and at risk, is telling the credit team they believe the numbers, and that supports a keener structure; one who wants out clean at a full price has the deal scrutinised harder. Press for some paper even where the seller would rather not. The terms worth negotiating, and a calculator for what the notes grow to, are in our guide to vendor loan notes.
They back the team that has run the numbers.
What a lender underwrites on a buyout is continuity. The borrowers already run the business, so the forecast is the incumbent team’s own plan, and a credit officer weighs the depth of that team, whether it is complete once the seller departs, and whether it can defend its figures in a room, alongside the usual tests of serviceability, earnings quality and security. The team’s own contribution matters less as a number than as evidence that its capital is at risk.
The bigger fork is whether a private-equity house backs the deal. A sponsorless buyout is the team buying alone; a search fund or independent sponsor, where an outside individual leads, is underwritten more like a buy-in. The table sets sponsor-backed against sponsorless.
Sponsor-backed and sponsorless buyouts, as a lender reads them.
| Row | Sponsor-backed | Sponsorless |
|---|---|---|
| Who stands behind the team | A private-equity house, whose fund can inject capital if a covenant tightens | The managers alone, with one balance sheet and no fund to top up equity |
| The lender field | More lenders will look | A narrower field |
| How far it is geared | Toward the ceiling, occasionally five times on a unitranche for a strong credit | Well inside what lenders would offer, sized on the downside case |
| What reassures the lender | The equity cushion and the sponsor’s track record | The management team, scrutinised harder, and more structure |
| Personal guarantees | Security over the company and its shares; the lender looks to the business, not the managers’ homes | A clearing bank routinely asks for one, sometimes with a charge over property |
| Junior or mezzanine debt | Can earn its place for a sponsor optimising returns | Usually a sign the price is too high for the debt |
A lender prices each on its own terms, and the sponsorless route rewards a team that presents its numbers credibly. The incumbent bank, which already knows the company, is the natural first conversation, but one quote with no competing bid is the weakest position from which to agree the leverage, the covenants and the vendor-paper treatment. The structuring differences are worked through in our note on search-fund and independent-sponsor debt.
The covenant package outweighs half a point on the rate.
On a buyout the covenant package deserves more attention than the margin, because a team geared to complete has the least room to absorb a technical breach. Bank senior debt carries maintenance covenants tested quarterly, typically leverage and interest cover; a unitranche fund often runs a single leverage covenant, or a covenant-loose package that springs only when the revolver is drawn. Push for headroom of at least 25 to 30% against your base case, an EBITDA definition that counts your legitimate add-backs, and an equity cure right. A cheap coupon with a tight covenant tested quarterly can hurt an MBO far more than fifty basis points on the rate, as our short answer on market covenants and what to push back on sets out.
Personal guarantees are the term owner-managers feel most, and Fig. 02 shows where they arise. Push back before the term sheet is signed: cap the guarantee at a fixed sum, carve out the family home, and have it fall away once leverage drops below an agreed level, as the full guide to personal guarantees works through.
Leakage controls, the permissions for dividends, management fees and other payments to shareholders, keep cash in the business while the debt is outstanding and deserve close reading where the owners are also the managers. The change-of-control clause typically makes the debt repayable if ownership changes again, so confirm what counts as a change before a later reorganisation or a partner buying in trips it.
Some buyouts fund themselves; some are asking too much of the debt.
An MBO financing is straightforward when the company is profitable and cash-generative, the price is sensible against the earnings, the team is complete, and the debt sits comfortably inside the 2.5 to 3.5 times a bank will lend. Senior debt then does most of the work, a slice of vendor paper closes the gap, and a clean raise of that kind runs twelve to sixteen weeks from mandate to money.
It needs structuring when the gap between what the debt can prudently carry and what the deal costs is wide. The answers are a smaller deal, buying a majority now and the rest later; more vendor paper; an equity partner, accepting the dilution as the price of a structure that will not break; or a year’s wait, since clean trading and a lower purchase multiple can turn a deal that only works in the good case into one that survives a bad one.
A junior or mezzanine layer can close the gap, but on an ordinary owner-managed buyout it usually means the price is too high for the debt. Mezzanine runs in the low to mid teens all-in, often part cash-pay and part payment-in-kind, and PIK at 12% rolling up unpaid grows the balance by roughly 57% over four years, quietly consuming equity value if the exit is slow. Our short answer on when junior debt makes sense sets out where it earns its place.
We will tell you what the debt can carry, and what it cannot.
If you are a team working out how to fund a buyout, the useful first conversation is how much debt the business can prudently carry, how vendor paper and any equity partner should fill the rest, and what a sensible completion structure looks like on the downside case. It is confidential and costs nothing. We run the whole market against itself, bank and fund, and will say when the deal needs less debt than it could raise, or when the honest answer is a smaller deal or a year’s wait.

The terms in this guide
Each is defined in full in the library, with the levels and conventions that apply at £3-15m.
- HoldCo vs OpCo debt
OpCo debt sits at the company that owns the assets and earns the cash. HoldCo debt sits one level above it, behind every creditor of the trading business, and is repaid only from what the trading company is permitted to pay up.
- 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.
- 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.
