Unitranche is a single loan package that merges what would traditionally be separate senior and subordinated debt layers into one facility with one blended interest rate and one lender syndicate.

How it works

In a classic leveraged buyout, the buyer might line up a senior term loan from banks and mezzanine debt from a different set of funds — each with its own covenants, pricing, and intercreditor agreement. Unitranche collapses that stack: direct lenders or private credit funds provide one commitment, often through an agent, at a rate between pure senior and pure sub debt. The blended coupon reflects the combined risk.

Borrowers gain speed — one negotiation, one closing — and simpler ongoing compliance. Lenders earn a wider spread than pure senior but avoid the complexity of sharing collateral with a mezzanine tranche. Unitranche is most common in middle-market private equity, typically on companies with predictable EBITDA. Venture-stage startups with negative cash flow rarely qualify; late-stage or PE-backed operators with recurring revenue sometimes use it for acquisitions or shareholder liquidity instead of raising primary equity.

Covenants still matter: leverage ratios, minimum liquidity, and reporting requirements can trigger defaults if performance slips.

Why it matters

• Founders: If your company matures toward PE-style cash flows, unitranche is an alternative to dilutive rounds — but it adds fixed obligations that survive bad quarters.
• Investors: Equity holders trade dilution for leverage risk. Unitranche sits above common stock in the capital stack; missed payments can force restructuring before equity sees anything.

Common mistake

Assuming unitranche is “cheap equity.” It is debt with covenants and repayment priority — inappropriate for pre-profit startups betting on hypergrowth.
