"Middle market" is one of the most used phrases in private credit, and one of the least precise. PC101 2.1 explained that most direct lending borrowers are middle-market companies and that lenders split the market into lower, core and upper bands. This lesson looks at how those bands are drawn and, more importantly, what changes as borrowers get bigger.
Size shapes almost every feature of a loan: how much debt the company can carry, how many covenants protect the lender, what spread it earns, and how much say it has if things go wrong. Analysts need this to judge whether a deal's terms are normal for its size. LP-side analysts use it to compare managers that sound alike but lend to very different companies. Investor relations and product teams need it to position a fund accurately, and service providers see the differences in the documents and reporting.
How the market is segmented
Most managers segment the market by the borrower's EBITDA (earnings before interest, taxes, depreciation and amortization), because it's a rough measure of the cash a company generates to pay its debt. Some use revenue or enterprise value instead.
There is no standard definition. Each manager, bank and data provider draws its own lines, and they move over time. Here is one illustrative split:
The following example is illustrative.
| Band | Illustrative borrower EBITDA |
|---|---|
| Lower middle market | Under $10m |
| Core middle market | $10m to $50m |
| Upper middle market | Over $50m |
Another manager might draw the lower band at $15m or $25m, or start the upper band at $75m or $100m. When a manager says it focuses on the "core middle market," always ask for its own range and check it against what the portfolio actually holds. Two funds using the same label can lend to very different companies.
What changes with size
As borrowers get larger, several features of the loan tend to shift. These are general patterns, not rules, and terms vary with market conditions.
| Feature | Lower middle market | Core middle market | Upper middle market |
|---|---|---|---|
| Leverage (debt to EBITDA) | Tends to be lower | In between | Tends to be higher |
| Financial covenants | Commonly one or more maintenance covenants | Commonly at least one maintenance covenant | Fewer covenants, sometimes none ("covenant-lite") |
| Pricing | Often the widest spreads | In between | Often the tightest spreads |
| Competition from the syndicated market | Little or none | Some, at the top of the band | Strong |
| Lender control | Greater | Moderate | Limited |
| Typical lender group | Often a sole lender | Sole lender or small club | Often a club of several lenders |
Why does this happen?
- Leverage. Larger companies often have more diverse customers, products and markets. Lenders tend to view them as more resilient and are willing to lend more against each dollar of EBITDA.
- Covenants. A maintenance covenant, tested every quarter, gives a lender an early warning and a seat at the table (PC101 3.4). Smaller borrowers have less margin for error, so lenders commonly insist on them. Larger borrowers can often negotiate them away.
- Pricing. Smaller companies are riskier on average and fewer lenders compete for them, so spreads are commonly wider. Larger deals attract more lenders, which pushes spreads down.
- Competition from the broadly syndicated market. Upper middle market borrowers can often choose between a private loan and a broadly syndicated loan, arranged by banks and sold to many investors (PC101 1.3). When the syndicated market is open and cheap, private lenders have to match its terms more closely. When it's closed or volatile, larger borrowers turn to private lenders and terms can tighten.
- Lender control. The more covenants, the smaller the lender group and the fewer alternatives the borrower has, the more influence a lender has when the company struggles.
Where sponsors and non-sponsors fit
The bands overlap with lesson 1.1. Non-sponsor borrowers such as Corrigan Tool & Die are commonly in the lower middle market, where the lender does more of the work and negotiates tighter terms. Sponsor-backed borrowers such as Pellworth Veterinary Group appear across all three bands, and competition for them rises with size.
This helps explain why a lower middle market fund may report a higher yield than an upper middle market fund. Part of the difference is pay for risk: smaller borrowers are more fragile. Part is pay for work and scarcity: fewer lenders compete. A higher yield alone doesn't tell you which fund offers the better return after losses (lesson 6.1).
Club deals vs. sole lenders
In a sole-lender deal, one fund provides and holds the whole loan. The lender controls every decision, from waivers to enforcement, and deals directly with the borrower. It also carries the whole exposure, which limits how large a loan a single fund can make without concentrating its portfolio.
In a club deal, a small group of lenders share the loan. One usually acts as the lead or agent, handling documents, payments and communication. Club deals let private lenders finance larger companies, often in the upper middle market, and let each fund keep its position size sensible. The trade-off is shared control: decisions such as waivers commonly need a majority of lenders, so each lender has less say. Sometimes the club includes a bank taking a first-out piece under an agreement among lenders (lesson 1.2).
For LP-side analysts, the mix of sole-lender and club deals is worth asking about. A manager that leads most of its deals commonly has more control and more direct information. A manager that mostly takes small shares of others' deals has less influence when problems arise.
Key terms
- Middle market: companies too large to be small businesses but usually too small to borrow easily in the public bond or syndicated loan markets.
- EBITDA: earnings before interest, taxes, depreciation and amortization, the most common yardstick for sizing borrowers.
- Leverage: a borrower's debt as a multiple of its EBITDA.
- Maintenance covenant: a financial test the borrower must meet every period, commonly quarterly.
- Covenant-lite: a loan with no maintenance covenants.
- Broadly syndicated loan: a loan arranged by banks and sold to many investors who can trade it.
- Sole lender: a single fund that provides and holds the whole loan.
- Club deal: a loan shared by a small group of lenders, usually with one acting as agent.
Key takeaways
- Managers commonly segment the middle market by borrower EBITDA, but the bands vary by manager and data provider.
- Always ask a manager for its own definition and check it against the portfolio.
- As borrowers get larger, leverage tends to rise, covenants loosen, spreads tighten and lender control falls.
- Upper middle market lenders compete directly with the broadly syndicated market.
- Club deals let lenders finance larger borrowers at the cost of shared control; sole lenders keep control but carry the whole exposure.
