Unitranche finance: combine senior and subordinated debt into one facility

Unitranche finance combines risk that might otherwise sit in separate senior and mezzanine facilities into one loan with one blended price. It is common in private-credit and acquisition finance because it can simplify execution and provide more leverage than conventional senior bank debt alone.

One facility replaces several debt layers

Instead of signing separate senior and mezzanine agreements, the borrower has one facility. The lender group can allocate senior and junior economics internally through arrangements that often sit behind the borrower-facing documents.

This can make completion simpler because the company deals with one principal financing structure.

One underwriting group can improve execution certainty

Acquisition borrowers value unitranche where a private-credit fund can approve a larger amount without a separate mezzanine process.

Fewer creditor groups reduce intercreditor negotiation, although legal, financial and commercial diligence remains substantial.

Blended pricing is normally above pure senior debt

The provider is taking risk that would otherwise sit partly in a subordinated layer, so the all-in coupon is usually higher than a traditional first-ranking bank facility.

Compare unitranche with the weighted cost of senior plus mezzanine and the value of certainty, speed and leverage.

Higher leverage increases downside exposure

Private-credit providers can support more leverage in some transactions than banks. That can reduce the buyer's equity contribution.

The extra leverage can also narrow covenant headroom. Model lower EBITDA, higher interest and slower synergy delivery before assuming the debt is comfortable.

Read covenants and call protection carefully

Unitranche documents can contain maintenance covenants, reporting obligations and prepayment premiums or call protection.

A company planning to refinance into cheaper bank debt after two years should calculate whether those exit charges reduce the expected savings.

Plan the refinance before the bullet date

Many unitranche facilities use light amortisation with a large maturity balance. Add a refinancing start date to the board debt calendar.

Improving leverage during the term can create access to cheaper finance later. If leverage stays high, the maturity can become difficult even after several years of manageable monthly payments.

Worked example: an acquisition requires £40 million of debt. A bank might provide £25 million senior and require a separate junior layer, while a private-credit fund offers £40 million unitranche at a higher blended rate. The buyer trades higher pricing for simpler execution and a smaller equity cheque.

Check lender transfer rights. Private-credit funds can transfer the debt to another institution under the agreement. Management should understand whether relationship quality depends on one fund manager who may not remain creditor for the full term.

Track all-in yield rather than cash coupon only. Original-issue discount, arrangement fees, PIK interest or exit fees can materially increase the effective cost of capital.

Use a downside exit model. If EBITDA is 20 percent below plan at maturity, calculate leverage and refinancing capacity at that level. Unitranche often reduces early amortisation, so a weak trading period can leave a larger principal balance exactly when replacement lenders become more conservative.

Check equity-cure provisions where the facility includes leverage covenants. Sponsors or shareholders can sometimes inject new equity to cure a covenant breach, but the amount, frequency and permitted use of cures vary. Do not assume owners can fix every breach by wiring cash at the last minute.

Monitor cash interest separately from any PIK component. A lower cash coupon can preserve liquidity while rolled-up interest grows the debt balance. Board reporting should show both today's bank outflow and tomorrow's redemption amount.

Compare unitranche with an equity-heavy structure in a downside case. The debt can preserve shareholder ownership when trading is strong but can transfer negotiating power to the lender if EBITDA falls. Ownership retention has value only if the company remains able to service the higher leverage.

Review permitted acquisition and capex baskets. Unitranche documents can be flexible but still restrict future investments. A growth strategy involving several bolt-on acquisitions should be tested against the facility terms before management assumes the committed debt will finance every opportunity.

Keep lender reporting tied to the business plan that supported the original underwriting. If the company shifts strategy materially, such as selling a division or entering a new country, review whether the facility permits the change before committing capital. Flexible private debt is still governed by contract.

Compare recurring reporting burden with the benefit of one lender group. Unitranche can simplify the capital structure, but private-credit providers can demand detailed monthly information. The company should have finance staff and systems capable of meeting that standard.

Review cash-sweep provisions after strong trading periods. Some facilities require a portion of excess cash to repay debt even when base amortisation is light. That can accelerate deleveraging but reduce funds available for acquisitions or dividends.
