Mezzanine lenders provide capital that is generally subordinated to senior debt in an operating company's financing structure. The practical research task is to identify the right borrower and transaction type, then compare cash obligations, deferred obligations, equity participation and the relationship with existing lenders.
This guide covers corporate mezzanine and junior-capital providers, not commercial real estate mezzanine loans. It compares PGIM's corporate mezzanine platform, Peninsula Capital Partners, Northstar Capital and Greyrock Capital Group. Use the capital-stack worksheet to organize a financing discussion with your advisers. A provider list alone cannot determine how much debt a company can safely carry.
What mezzanine financing does, and what the label leaves unanswered
PGIM's borrower page places mezzanine financing between senior debt and equity and describes cash interest, deferred interest and possible warrants. Its listed uses include growth, acquisitions and recapitalizations.
Those features are not a universal term sheet. Ask about the actual instrument, repayment, security, covenants and intercreditor arrangements. A product advertised as junior capital may involve debt, preferred equity or a combination. A unitranche product should not automatically be classified as a separate subordinated loan.
| Research field | What to distinguish | Who needs to review it |
|---|---|---|
| Borrower and purpose | Operating-company expansion, acquisition, recapitalization or another use | Management and finance lead |
| Capital instrument | Subordinated debt, preferred equity, common equity or a combined package | Finance team and transaction advisers |
| Cash obligation | Interest and principal requiring cash at each date | Accountant or finance adviser |
| Deferred obligation | Interest or return that accrues rather than disappearing | Accountant or finance adviser |
| Rights and priority | Security, restrictions, consent rights and relationships among lenders | Attorney and relevant lenders |
Four corporate mezzanine lenders and junior-capital providers
The table uses current first-party criteria, not estimated approval odds or a rate ranking. It deliberately separates documented scope from questions that require a lender conversation. Public investment ranges and example transactions are not quotes for your company.
| Provider | Verified route | Useful fit evidence | Important question |
|---|---|---|---|
| PGIM / Prudential Private Capital | Corporate mezzanine and preferred equity | Growth, acquisitions, buyouts, recapitalizations and related financing uses | Which team, instrument and obligations fit this borrower and purpose? |
| Peninsula Capital Partners | Subordinated debt and preferred or common equity | Established middle-market companies with profitable operating history; explicit exclusions | Does the company satisfy current profitability and sector criteria? |
| Northstar Capital | Sponsored transactions; subordinated debt, unitranche and equity co-investment | U.S. and Canadian companies with stable cash flow and profitability | Is this a sponsored transaction, and which product is actually proposed? |
| Greyrock Capital Group | Mezzanine debt and equity; junior capital for independent sponsors | Middle-market buyouts, recapitalizations and internal growth | How does the package differ for a private equity sponsor versus an independent sponsor? |
PGIM: start with the corporate borrower route
The cited corporate mezzanine page now uses PGIM branding on the Prudential Private Capital domain. Treat this as one platform, not separate lenders created from historical names. Its page identifies corporate mezzanine team contacts and distinguishes subordinated debt from preferred equity.
Use the official borrower route to investigate the appropriate team. Ask how cash payments, deferred amounts, principal repayment and any equity component would appear in a complete proposal. Do not adopt a provider's promotional cost comparison as proof that mezzanine is cheaper or better for your business.
Peninsula: read the exclusions as carefully as the capabilities
Peninsula's criteria describe capital for acquisitions, expansion and recapitalizations, a history of profitability and a published minimum EBITDA criterion. Its page also states sectors and situations it generally avoids, including distressed businesses and several industry categories.
For a preliminary screen, an explicit exclusion is more useful than a broad “generalist” label. Recheck the criteria before outreach. Prepare a consistent operating-history summary and explain management's plan. Do not interpret a published term range as an offer or transfer it onto another provider.
Northstar: verify the sponsor and product fit
Northstar Capital identifies sponsored transactions, stable cash flow and profitability, and a U.S. and Canada focus. It lists subordinated debt, unitranche and equity co-investment as distinct products.
An unsponsored founder financing should not be marked qualified simply because its industry appears relevant. Clarify the sponsor requirement and transaction structure. Record the exact company identity and domain too: unrelated businesses with similar Northstar names are not evidence of this provider's criteria.
Greyrock: distinguish sponsor relationships
Greyrock describes mezzanine debt and equity for middle-market buyouts, recapitalizations and growth. It separately discusses mezzanine capital for private equity sponsors and junior-capital relationships with independent sponsors.
Prepare the transaction-role map alongside the company summary. Who sponsors the deal, who supplies equity, who manages operations and who can authorize diligence? A provider's experience in one sponsor model does not automatically answer how an owner-led transaction would be handled.
Worked example: make cash and deferred obligations visible
Illustrative educational example, not actual financing terms or a recommendation: Harbor Instruments is considering a $20 million acquisition funding plan. A draft model contains $11 million senior debt, $4 million subordinated debt and $5 million equity. The arithmetic totals $20 million, but does not establish debt capacity, valuation or lender approval.
| Illustrative source | Amount | What remains to verify |
|---|---|---|
| Senior debt | $11 million | Actual facility, security, repayment and consent requirements |
| Subordinated debt | $4 million | Cash and deferred return, maturity, rights and intercreditor terms |
| Equity | $5 million | Ownership, governance and any future funding obligations |
| Total modeled sources | $20 million | Reconcile with acquisition price, expenses and working-capital uses |
Suppose, solely to demonstrate the math, the first-year junior-debt model uses 8% cash interest and 3% deferred interest on an unchanged $4 million opening principal, without intra-year compounding or amortization. Cash interest is $4,000,000 × 8% = $320,000. Deferred interest is $4,000,000 × 3% = $120,000. If that deferred amount is capitalized at year end, the modeled balance becomes $4,120,000.
The $120,000 is not free capital and is not a cash saving that can be assumed forever. Later periods depend on the actual contract, compounding and repayments. The simplified example excludes fees, warrants, taxes, senior-debt service and operating cash needs. A finance professional should rebuild the full schedule from the real proposal and test downside cases.
Harbor's next step is not to declare the junior loan affordable. It is to reconcile the complete sources and uses, model every cash requirement and ask advisers which obligations could constrain the business under a slower operating case.
Copy the subordinated-capital research worksheet
Keep model assumptions separate from lender-confirmed terms. A blank field is preferable to an estimated covenant or a rate copied from another transaction.
| Field | Your entry | Verification owner |
|---|---|---|
| Borrower, sponsor and purpose | [Exact entities and transaction] | [Management / adviser] |
| Current operating evidence | [Cash flow, profitability, working capital and concentration] | [Finance lead] |
| Provider and product | [Exact platform; subordinated debt / other instrument] | [Official source and date checked] |
| Sources and uses | [Senior, junior, equity, expenses and company cash] | [Finance adviser] |
| Cash and deferred return | [Confirmed terms or unconfirmed] | [Full dated schedule required] |
| Principal, maturity and fees | [Proposed repayment and all expenses] | [Accountant / finance adviser] |

| Lender rights and restrictions | [Issues to review, not assumed conclusions] | [Attorney and existing lenders] |
| Downside case | [Operating stress and resulting cash requirements] | [Management and finance lead] |
| Next research action | [Question, responsible person and review date] | [Permissioned official route] |
What to prepare before a lender conversation
- Explain the purpose. Separate acquisition price, growth spending, shareholder proceeds, refinancing and expenses.
- Reconcile cash flow. EBITDA is not automatically cash available for debt service. Show working capital, capital expenditure and other obligations in the model.
- Classify every instrument. Do not label a unitranche or preferred-equity proposal as subordinated debt merely to make comparison easier.
- Test an operating downside. Show how slower collections, lower margins or delayed growth affect cash needs. Do not assume refinancing will always be available.
- Assign professional questions. Have counsel review restrictions, priority and consent issues; have an accountant or finance adviser check the full economics.
Use the assumptions and scenarios lesson to organize model inputs and the commercial-diligence guide for business evidence. If the underlying need is an ownership sale rather than borrowing, revisit that objective before comparing loan products.
Research scope and disclaimer
Finta reviewed the linked official provider pages on October 20, 2026. The comparison covers four documented corporate junior-capital routes, not all mezzanine lenders. It does not rank pricing, predict approval or estimate remaining investment capacity. Current criteria and an actual written proposal control the transaction discussion.
