Mezzanine Financing: How It Works and Who Uses It

Mezzanine financing is a loan that ranks below senior debt and above common equity. It usually costs more than a bank loan, and many mezzanine deals add an equity kicker, a right to a share of the upside if the company is sold or goes public. Companies use it when they need more capital than senior lenders will provide without giving up as much ownership as a full equity raise would require.

This guide explains how the structure works, walks through a worked example, lists the main downsides, and shows how the process of finding a mezzanine lender typically runs.

Where mezzanine sits in the capital structure

A company's capital is stacked in layers. Senior debt, usually a bank or senior lender loan, is repaid first and is often secured by the company's assets. Equity sits at the bottom and absorbs losses first. Mezzanine financing sits in the middle: it is repaid after senior debt but before equity holders.

Because mezzanine lenders take more risk than senior lenders, they expect a higher return. That return usually comes from two sources:

• Interest. A cash coupon, often fixed, paid over the life of the loan. Some deals accrue part of the interest instead of paying it in cash.
• Equity upside. Warrants or an equity kicker that gives the lender a small ownership stake or a payment tied to a sale or public listing.

Mezzanine loans are often unsecured or sit behind the senior lender's security. The lenders' rights and the order of repayment are set out in an intercreditor agreement.

A worked example

Here is a simple case from Growth Lending. An established business wants to buy a smaller rival for £5 million. The structure is:

Layer	Amount	Role
Company equity	£2 million	Owner's own capital
Senior bank debt	£2 million	Lowest-risk debt, lower rate
Mezzanine loan	£1 million	Fills the gap, higher risk and higher rate

In that example, the mezzanine piece is the £1 million that the bank will not lend. The source describes the mezzanine loan as carrying something like a 12% interest rate, plus a 2% equity kicker if the company sells or floats within five years. The senior loan in the same example is priced lower, at around 7%. These are illustrative numbers from one example, not market averages, and actual terms depend on the company, the lender and the deal.

The example shows the trade-off clearly. The company gets the full £5 million without giving up the equity share a larger equity raise would cost, but it pays more for the mezzanine layer than for the bank debt.

When companies use mezzanine financing

Mezzanine is most common in these situations:

• Acquisitions, where the buyer needs debt beyond what the senior lender will provide.
• Growth or expansion, such as a new site, a product launch or a large contract that needs upfront capital.
• Recapitalizations, where owners want to take cash out or restructure existing debt without selling control.
• Ownership protection, where founders prefer debt with a capped equity cost to a larger equity round.

It is generally used by companies with steady cash flow that can cover interest payments. Lenders look closely at earnings, leverage and how well the business can service the total debt.

What are the downsides?

Mezzanine financing has real costs and risks:

• Higher cost than senior debt. The interest rate is higher, and the equity kicker adds to the total cost if the business does well.
• Dilution. Warrants or equity kickers reduce the owners' share of future value.
• Subordination. In a default or liquidation, mezzanine lenders are paid after senior lenders, which is why they price the risk.
• Covenants. Loan agreements may limit dividends, additional debt, asset sales or changes in ownership.
• Complexity. The intercreditor agreement, warrant terms and repayment schedule need careful review, usually by counsel.

A business should model its cash flow under weaker-than-expected results before signing. If the interest payments would strain the company in a bad year, the structure is too aggressive.

Mezzanine stage financing is a different thing

You may see the phrase "mezzanine stage financing" in venture capital contexts. It refers to a late funding round before an IPO or acquisition, when a startup is growing quickly but is not yet profitable. It is a funding stage, not a debt layer, so do not confuse it with the capital structure meaning covered on this page.

How to find a mezzanine lender

Mezzanine lenders include private credit funds, specialist mezzanine funds, business development companies and some insurance-backed lenders. Each has its own criteria for deal size, industry, earnings, geography and loan type.

A practical way to start is to prepare:

• Three years of financial statements and the current year's forecast
• The total amount needed and what it will fund
• Current senior debt, if any, and its terms
• A summary of the business, its customers and its management team
• The ownership structure and any planned exit

The right lender depends on deal size and fit. Some lenders only look at larger transactions, and a smaller request may not match their criteria even if the business is sound.

Thrive Funding is a private credit arranger for middle-market companies. It does not lend money itself. Borrowers submit one application, and Thrive matches it against private lending groups whose criteria fit the deal size, industry, geography and loan type. Requests under $1 million are declined automatically. Matching groups receive an anonymous deal summary, and up to three that say yes are introduced to the borrower. Each lender makes its own credit decision and issues its own term sheet. Thrive is paid by its lending partners, not by borrowers. Any terms Thrive shares before a lender issues a term sheet are indicative terms only, not an offer.

Whether you go direct to a lender or use an arranger, compare the full cost: interest, any equity kicker, fees, and the covenants that will shape how you run the business.
