Mezzanine Financing: Terms, Returns and When It Fits

Mezzanine financing is hybrid capital that sits between senior debt and equity. It is usually a subordinated loan with a high coupon (mostly cash, sometimes partly accrued) and an equity kicker such as warrants, so the lender is repaid like a creditor but shares some upside. Companies often use it when senior borrowing is maxed out and owners don't want to sell a large stake.

It's the capital you reach for when the bank won't lend another dollar and you're not ready to sell a big slice of equity.

In exchange for the junior position, lenders aim for blended returns well above senior debt. Oaktree's mezzanine strategy primer says investors have historically targeted gross returns in the mid-teens, and training resources such as Financial Edge and Wall Street Oasis put typical ranges at roughly 12 to 20 percent, varying with rates and risk.

Definition: Mezzanine financing is subordinated debt, often unsecured, that ranks below senior loans and above equity, carries a high cash or payment-in-kind interest rate, and usually includes warrants or conversion rights that give the lender a small equity participation.

Where mezzanine financing sits in the capital stack

Think of the capital stack as a line at the exit. Oaktree's primer sketches a typical leveraged structure of roughly 30 to 40 percent senior debt, 10 to 20 percent mezzanine, and 30 to 50 percent equity, and says mezzanine usually takes the form of senior unsecured or subordinated notes, or second lien debt. In a default, senior lenders are paid first from their collateral, mezzanine lenders come next, and equity holders get whatever is left.

PGIM Private Capital calls mezzanine "the last stop along the capital structure" where owners can raise substantial capital without selling a large stake. It adds that senior lenders often view mezzanine as equity-like, patient capital, and frequently prefer it to second lien loans, partly because they can block its current interest payments if trouble starts.

Mezzanine financing terms, one by one

• Coupon. Higher than senior debt, lower than the cost of equity. Oaktree's 2016 primer put coupons at 11.0 to 12.5 percent, which it called the low end of the historical range, with an illustrative split of 11 percent cash and 0 to 1.5 percent PIK.
• Cash versus PIK interest. Payment-in-kind interest is added to principal instead of paid in cash. It protects the borrower's cash flow today and quietly compounds the balance owed tomorrow.
• Fees. Oaktree cites 2 to 3 points up front, paid directly or through original issue discount.
• Maturity. Oaktree describes a 6 to 7 year instrument; PGIM cites maturities of up to 7 to 8 years, typically falling a year after the senior debt matures, with interest-only payments and no amortization before maturity.
• Warrants or conversion rights. The equity kicker. Moonfare notes that warrants give the lender the right, but not the obligation, to buy a predetermined number of shares at a set price, and some structures let the lender convert the debt itself on a liquidity event or milestone. Oaktree also buys equity directly alongside some of its mezzanine loans.
• Covenants. PGIM describes them as looser than a bank loan's, though Oaktree notes that, unlike covenant-lite debt to large issuers, loans to middle-market businesses still carry both incurrence and maintenance covenants.
• Call protection. Oaktree cites 1 to 2 years of no prepayment, then a schedule of prepayment premiums, which protects the lender's yield if the borrower refinances with cheaper debt.

Worked example: a buyout funded with mezzanine

An illustrative example: a private equity sponsor buys a company with $4M of EBITDA for $30M (7.5x). The bank lends $12M of senior debt at 8 percent, a mezzanine fund adds $6M at a 12 percent cash coupon plus 3 percent PIK with warrants for 2 percent of the equity at a nominal exercise price, and the sponsor puts in $12M. That is a 40/20/40 split, and total debt is 4.5x EBITDA.

Now the sponsor's side. After the $3.6M of mezzanine cash coupons paid over five years, its 98 percent of the equity is worth roughly $36.6M, about 3.1x its $12M. Funding the same $6M with more equity instead would leave the sponsor with $48M on $18M, about 2.7x. Mezzanine didn't make the sponsor more money here. It made the sponsor's money work harder: a higher multiple on less capital, not more total dollars. The figures are hypothetical and ignore taxes, fees, and senior debt paydown.

Two meanings of "mezzanine" in venture

The term is used two ways. The Institutional Limited Partners Association (ILPA) glossary defines mezzanine capital as subordinated debt or preferred stock with an equity kicker, used largely in buyout-type deals. The same glossary defines mezzanine financing as the stage of venture financing immediately before an IPO, which can be structured as preferred stock, convertible bonds, or subordinated debt.

If a founder mentions raising mezzanine, ask which one they mean. The answers describe very different deals. The related instrument for venture-backed companies without meaningful EBITDA is venture debt, which is usually senior and secured, sized against the company's latest equity round, and priced with a small warrant package.

How investors underwrite mezzanine financing

Mezzanine funds underwrite cash flow, not vision. Common questions include:

1. Coverage. Can EBITDA cover senior interest plus the mezzanine cash coupon in a downside case? Oaktree's primer targets interest coverage of 2.0x or better.
2. Leverage. Total debt to EBITDA, including the mezzanine layer. Oaktree aims to keep total debt at 4.0x to 6.0x EBITDA or less.
3. Exit path. Wall Street Prep stresses that mezzanine is not a long-term source of capital, so the lender usually wants a plausible refinancing or sale within the term.
4. Kicker value. Warrants or co-invested equity are sized so the blended return hits the fund's target; Oaktree aims for its equity to add 100 to 200 basis points.
5. Intercreditor terms. What the mezzanine holder may do if the company misses a payment, including standstill periods and payment blocks.

For equity investors: mezzanine ahead of you is a claim that generally gets paid before your stock is worth anything, and PIK interest makes it bigger every year. We'd model it in the same waterfall you build for a liquidation preference; the IRR guide explains the return math.

When mezzanine financing fits, and the alternatives

Our take: mezzanine usually costs more than a bank loan and less than selling equity, and it tends to work only for a business that can pay the coupon out of real cash flow. For an early-stage startup that burns cash, that's usually a reason to skip it. The growth equity guide covers the equity side of the same decision, private equity vs. venture capital explains the buyout world where mezzanine is most common, and the private credit vs. venture capital comparison explains why the two investor types think so differently.

Seeing capital structure decisions inside a working fund

Most new angels meet a mezzanine or venture debt layer for the first time when it turns up above them in a portfolio company's capital stack, often without much warning. Seeing those layers added in real time is what 1752vc's Emerging Angels program is for: eight live weeks in which accredited investors new to angel investing sit in a working fund's deal reviews and diligence calls rather than reading the outcome afterwards.

The bottom line

Mezzanine is a tool for companies that already make money and want to keep more of the upside. It's expensive, it's patient, and it gets paid before you do.

For the borrower, it's cheaper than equity.

For everyone below it, it's a bill that keeps growing.
