Vendor Loan Notes Explained: Why a Seller Finances the Buyer, Where the Note Ranks in the Debt Stack, and How It Lifts the Sponsor's IRR

Michael King, PE Investment Manager · 9 min read ·

Key takeaways
  • A vendor loan note is deferred consideration structured as a debt instrument: instead of taking all the price in cash at completion, the seller lends a slice of it back to the buyer and is repaid later with interest. It is the seller financing the purchase of its own business, and in UK and European mid-market deals it typically fills 5–20% of the price
  • It ranks junior to every bank in the structure — senior, second lien and mezzanine all sit ahead of it — and above the ordinary equity. The interest is usually PIK, rolling up rather than paid in cash, so it drains no cash flow during the hold and reads to senior lenders as quasi-equity
  • It is cheaper than equity, so replacing part of the sponsor's cheque with a vendor note is IRR-accretive in exactly the way leverage is: a note costing 8% displaces equity that was targeting north of 20%. In a worked deal a £15m note lifts the sponsor's return from roughly 19% to 23%
  • The alignment story — "the seller believes in the business" — is real but secondary. The note is subordinated, PIK and subject to set-off against warranty claims, so the seller has converted certain cash into an at-risk claim on a business it no longer controls. The buyer takes it because it is the cheapest capital available, not because the seller insisted

A Vendor Loan Note Is the Seller Financing Its Own Sale

A vendor loan note is a promise from the buyer to pay the seller a fixed sum, later, with interest — issued in place of cash the seller would otherwise have received at completion. The seller hands over the business, takes most of the price in cash, and accepts a loan note for the balance. In substance the seller has become a lender to the person who just bought it.

The reason it exists is arithmetic. A buyer can only pay what it can fund, and the funding is the sum of the debt lenders will advance and the equity the sponsor will write. When that total falls short of the price the seller will accept, there are three ways to close the gap: the buyer raises more equity, the seller cuts the price, or the seller lends the difference back. The vendor note is the third option, and it is frequently the cheapest for everyone at the table — which is why a tool that looks like a concession from the seller is usually proposed by the buyer.

Where It Sits: Junior to Every Bank, Senior to the Equity

A vendor note only makes sense once you can place it in the capital structure, because its entire risk profile comes from its rank. It is contractually subordinated — through the intercreditor agreement — to all the bank debt: the senior term loans, any second lien, any mezzanine. It is not repaid, and often cannot even receive cash interest, until the senior lenders have been dealt with. In a payment default it sits behind every one of them.

Above the equity is where it earns its keep. The note ranks ahead of the ordinary shares and, depending on what the sponsor negotiates, either alongside or behind the sponsor's own shareholder loan notes in the Topco structure. Its interest is almost always PIK — it accrues to principal and is settled in a bullet at exit rather than paid in cash — which is precisely why senior lenders tolerate it. A junior instrument that takes no cash out of the business during the hold does not compete with the banks for debt service, so they treat it as quasi-equity that happens to have a fixed coupon.

The note is priced like debt but ranks like equity This is the tension that defines the instrument. The seller is paid a fixed return — a coupon, not a share of the upside — which is the economics of a lender. But the note is deeply subordinated, unsecured, and repaid only after every bank and only if the deal works, which is the risk position of an equity holder. The seller has taken equity-grade risk for a debt-grade return. That mismatch is the hidden cost of the note, and it is why the coupon, however high it looks, rarely compensates for what the seller is actually exposed to.

That subordination is abstract until you price it against the alternative the sponsor was going to use, which is its own equity.

A Worked Deal: £15m of Vendor Financing Lifts the Sponsor's IRR by Four Points

Take a business bought for a £100m enterprise value on £12.5m of EBITDA — 8.0x. The buyer can raise £50m of senior debt. The gap to the price is £50m, and the question is how to fund it. Compare funding it entirely with sponsor equity against funding £15m of it with a vendor loan note carrying 8% PIK interest, held for five years to an exit at the same 8.0x on £17.5m of EBITDA — a £140m exit enterprise value, with senior debt paid down to £20m from cash flow.

MetricNo vendor noteWith £15m vendor note (8% PIK)
Senior debt£50m£50m
Vendor loan note£15m
Sponsor equity£50m£35m
Exit enterprise value£140m£140m
Less: senior debt at exit(£20m)(£20m)
Less: vendor note repaid (£15m × 1.08⁵)(£22m)
Proceeds to sponsor equity£120m£98m
Money multiple2.4x2.8x
IRR (5-year hold)~19.1%~22.9%

The note absorbs £22m at exit — more than it started at, because the PIK coupon rolled up. Yet the sponsor is better off, because the £15m of vendor financing displaced £15m of equity that would have shared in the same £120m of upside. Paying 8% on capital that stands in for equity targeting 23% is accretive, and the accretion is the whole point.

+3.8pts The lift in the sponsor's IRR — from roughly 19.1% to 22.9% — from funding £15m of a £100m deal with an 8% vendor note instead of equity. The note is a form of leverage the sponsor sources from the seller rather than from a bank, and it enhances returns for the same reason all leverage does: its cost sits below the return on the equity it replaces

Why the Buyer Wants It: Cheap Capital and a Seller with Skin in the Game

The return maths is the first reason, but not the only one. A vendor note also solves problems that cash cannot. It closes a genuine funding gap without forcing the sponsor to over-equitise a deal or the lenders to stretch senior leverage past what the credit supports. And because the note is money the seller only gets back if the business performs, it keeps the seller aligned after completion in a way a clean cash exit never does.

That alignment doubles as security. A vendor note is a natural home for a right of set-off: if a warranty or indemnity claim surfaces after completion, the buyer can withhold the disputed amount from what it owes on the note rather than chasing the seller for a refund it has already spent. A note the buyer still owes is far easier to claw back than cash already paid, which is why buyers often size the note with an eye on the warranty exposure, not just the funding gap.

Why the Seller Accepts It: The Price of the Deal Clearing (and a Tax Deferral)

A seller takes a note for the same reason a buyer offers one — because the alternative is a lower headline price or no deal. If the market will not fund the seller's number in cash, a vendor note is the bridge between the price the seller wants and the cash the buyer can raise, and a seller who refuses it may simply be repricing its own business downward.

There is often a tax attraction on top. Structured as loan notes rather than cash, part of the consideration can, depending on the seller's circumstances and how the notes are drawn, defer the capital gains charge until the notes are redeemed rather than crystallising it in full at completion — spreading the gain across tax years. It is a real driver for a founder seller, but the reliefs around it have been narrowed over successive UK budgets and the treatment turns on the fine detail of the instrument, so it is entirely advice-dependent and never the reason to take a note on its own.

What the seller is actually signing up to The coupon flatters the note. A seller taking £15m of vendor paper has converted certain, spendable cash into a claim that is subordinated to £50m of bank debt, unsecured, non-cash until exit, exposed to set-off against any warranty claim, and repayable only if a business it no longer runs performs well enough to clear the banks first. In the deal above the note works and returns £22m; in a downside where the exit barely covers the senior debt, the same note recovers little or nothing, and the seller has no seat at the table to do anything about it. The interest rate is compensation for lending. It is not compensation for taking equity risk on the buyer's business.

Vendor Loan Note vs Earn-Out vs Rollover: Three Ways to Defer, Three Different Risks

The vendor note is one of a family of tools that leave part of the price on the table after completion, and the strong candidate never confuses them, because each puts the seller in a different position relative to the business it sold.

InstrumentSeller's positionReturnDepends on
Vendor loan noteSubordinated creditorFixed interest (usually PIK)Business clearing the senior debt by exit; no performance target
Earn-outContingent claimantPayment only if targets are hitThe business hitting a revenue or EBITDA metric the buyer now controls
Rollover equityCo-ownerShare of the equity upsideThe full exit outcome — same risk and reward as the sponsor's shares

The distinction that matters is contingency. A vendor note is a fixed obligation — the sum is certain, only the recovery is at risk through subordination — whereas an earn-out is contingent by design, paying nothing unless the business hits a target. Rollover equity goes further still, making the seller an owner who shares the sponsor's upside and downside in full. Ranked by risk the seller carries, it runs rollover, then vendor note, then earn-out, then plain deferred consideration — and the right tool depends entirely on where the disagreement sits. A funding gap wants a vendor note; a forecast dispute wants an earn-out; a desire to keep the founder motivated wants rollover.


The Verdict: Alignment Is the Story, Leverage Is the Reason

Vendor loan notes are sold with the language of partnership — the seller keeping faith with the business, staying invested, sharing the journey. That framing is not false, but it is the cover story. The reason a vendor note appears in a structure is that it is the cheapest capital available: subordinated, PIK, IRR-accretive financing that the buyer would have to replace with more expensive equity if the seller declined it. The alignment is a genuine by-product; the cost of capital is the motive.

Seen that way, the note is a transfer of risk dressed as a gesture of confidence. The seller lends because the deal does not clear at its price otherwise, and in doing so it takes equity-grade subordination for a debt-grade coupon on a business it has already handed over. When the deal works, everyone is happy and the note looks like the smart, aligned structure it was billed as. When it does not, the vendor note is a quiet casualty ranking just above the wiped-out equity — and the seller discovers that the coupon was never the price of the risk it was actually carrying.

How It Is Tested: "How Would You Fund the Gap?"

The question usually arrives as a sources-and-uses problem: here is the price, here is the debt the banks will lend, here is the equity the fund will write — and there is a hole. The weak answer raises more equity or cuts the price. The strong answer reaches for a vendor loan note, and then explains what it costs whom.

Interview framing Name the vendor note, then price it against the equity it replaces — that is the insight the question is testing. Say that an 8% PIK note sitting below the banks and above the ordinary equity is cheaper than the fund's equity, so it lifts the sponsor's IRR the way any leverage does, and that senior lenders accept it because the PIK coupon takes no cash out of the business. Then flip to the seller's side unprompted: the note is subordinated, non-cash and exposed to warranty set-off, so the seller has taken equity risk for a fixed return. Closing with the distinction from an earn-out — a vendor note is a fixed obligation, not a contingent one — is what signals you understand the structuring toolkit rather than a single trick.

Careers: The Associate Sizes the Note and Negotiates Its Subordination

On a live deal a vendor note is an associate's line in two places. First in the model, where it is a source of funds that shrinks the equity cheque and a PIK balance that compounds on the debt schedule until exit, feeding straight into the returns the investment committee sees — misplace its rank in the exit waterfall and the equity IRR is wrong. Then in the negotiation, where the note's real terms are settled: how deeply it subordinates to the senior debt, whether it can take cash interest or must roll up, how the warranty set-off works, and where it ranks against the sponsor's own shareholder instruments.

That second job is where the associate learns that the note is not a rounding item. The sponsor wants the vendor note pushed as far down the structure as the seller will accept and the coupon held as low as the deal allows, because every basis point and every notch of subordination is value transferred from the seller to the fund's equity. The seller's advisers want the reverse. The compromise that lands in the intercreditor is the associate's to model and, increasingly, to argue.

Anyone can say a vendor loan note is "the seller lending part of the price back" — that is the definition. The judgement is knowing why it is there: that it is the cheapest capital in the structure, that it lifts the sponsor's return by standing in for equity, and that the seller has taken equity-grade risk for a debt-grade coupon on a business it no longer controls. Reading the note as a cost-of-capital decision wearing the costume of alignment is the difference between someone who has funded a deal and someone who has read the term sheet.

Frequently asked questions

What is a vendor loan note?

A vendor loan note is a form of deferred consideration in which the seller of a business accepts a loan note — an interest-bearing IOU from the buyer — in place of part of the cash price at completion. Instead of being paid in full on day one, the seller receives most of the price in cash and lends the balance back to the buyer, to be repaid later with interest. In effect the seller helps finance the purchase of its own business. In UK and European mid-market deals a vendor note typically funds somewhere between 5% and 20% of the price, and it is used to bridge the gap between what the seller will accept and what the buyer can raise in debt and equity.

Where does a vendor loan note rank in the capital structure?

It ranks junior to every bank in the structure and senior to the ordinary equity. Through the intercreditor agreement it is contractually subordinated to the senior debt, any second lien and any mezzanine, so it is not repaid — and often cannot even take cash interest — until the bank lenders have been satisfied. Above the equity, it ranks ahead of the ordinary shares and, depending on what the sponsor negotiates, either alongside or behind the sponsor's own shareholder loan notes. Its interest is usually PIK, accruing to principal and repaid in a bullet at exit rather than paid in cash, which is why senior lenders treat it as quasi-equity: it takes no cash out of the business during the hold and does not compete with them for debt service.

Why would a seller agree to a vendor loan note?

Because the alternative is usually a lower price or no deal. If the market will not fund the seller's number in cash, a vendor note is the bridge between the price the seller wants and the cash the buyer can raise. There can also be a tax attraction: structured as loan notes, part of the consideration can, depending on the seller's circumstances and the detail of the instrument, defer the capital gains charge until the notes are redeemed rather than crystallising it in full at completion — though the UK reliefs around this have been narrowed and the treatment is entirely advice-dependent. The trade-off is real risk: the note is subordinated, non-cash until exit, and exposed to set-off against warranty claims, so the seller has converted certain cash into an at-risk claim on a business it no longer controls.

What is the difference between a vendor loan note and an earn-out?

The difference is contingency. A vendor loan note is a fixed obligation — the amount owed is certain, and only its recovery is at risk through subordination to the bank debt. It pays a fixed rate of interest and does not depend on the business hitting any target. An earn-out is contingent by design: it pays nothing unless the business reaches an agreed revenue, EBITDA or milestone target after completion, and the buyer that now controls the business also controls the number the payment depends on. A vendor note bridges a funding gap; an earn-out bridges a disagreement about future performance. Ranked by the risk the seller carries, rollover equity is the most exposed, then the vendor note, then the earn-out, then plain deferred consideration.

Why do private equity buyers like vendor loan notes?

For three reasons. First, cost: a vendor note is cheaper than equity, so replacing part of the sponsor's cheque with a note is accretive to the equity IRR in the same way leverage is — an 8% note standing in for equity targeting north of 20% enhances returns. Second, funding: it closes a genuine gap without forcing the fund to over-equitise the deal or the lenders to stretch senior leverage. Third, alignment and security: because the seller only gets the note back if the business performs, it keeps the seller invested after completion, and the outstanding note is a natural source of set-off if a warranty or indemnity claim arises, since money still owed is far easier to claw back than cash already paid.
