Refinancing vs assuming existing business debt

A business rarely arrives at a sale debt-free. Equipment loans, a commercial mortgage against owned real estate, or a working capital facility are often still outstanding when a deal closes, and a buyer has to decide, deal by deal, whether that existing debt gets paid out and replaced or carried forward under the buyer’s name instead. The two paths look similar on paper — either way, the buyer ends up responsible for financing the business going forward — but they work quite differently in practice.

Refinancing

Refinancing has the seller’s existing loan discharged at or before closing, using a portion of the sale proceeds or a bridging arrangement to pay it out, while the buyer separately arranges entirely new financing underwritten fresh, in their own name, against their own creditworthiness and the business as it will operate under new ownership. This is the more common path in an asset sale, where the buyer is generally not taking on the seller’s corporate liabilities unless specifically agreed, and the existing lender’s registered security over the assets purchased needs to be discharged so the buyer’s new lender can register a clean claim of its own. It is also frequently the more common path even in a share sale, since many buyers and their lenders prefer to start with financing structured entirely on their own terms rather than inheriting someone else’s.

• Existing debt is paid out and discharged at or before closing, typically as a condition of closing itself
• The buyer’s new lender underwrites the loan fresh, independent of the seller’s original terms
• The existing lender’s registered security needs to be formally discharged so a new lender can register clean
• Usually the natural path in an asset sale, and often preferred even in a share sale for a clean financing start

Assuming existing debt

Assuming existing debt has the buyer step directly into the seller’s loan, taking over the remaining obligation rather than replacing it with something new — but this is rarely as simple as it sounds, because most commercial loan agreements contain a change-of-control or due-on-sale clause requiring the original lender’s consent before an assumption can happen at all. Even where the lender agrees, it will generally re-underwrite the buyer as the new obligor, much as it would for a new loan, and the original terms may or may not carry forward unchanged. A share sale is the more natural setting for this, since the buyer is acquiring the corporation as it stands, debt included — but the outgoing seller, particularly if they gave a personal guarantee on the original loan, still needs a formal, written release from the lender, or they can remain personally exposed to that debt long after they have handed over the business.

• Requires the original lender’s consent — most loan agreements restrict a change of control without it
• The lender typically re-underwrites the buyer as the new borrower, even where the debt itself continues
• More naturally fits a share sale, where the buyer is acquiring the corporation including its existing liabilities
• A seller who gave a personal guarantee needs a written release from the lender, not just an informal understanding with the buyer

How to choose

Whether refinancing or assuming existing debt is realistic often comes down to the deal structure chosen for other reasons — an asset sale generally points toward refinancing, since the buyer is not automatically taking on the seller’s liabilities in the first place, while a share sale at least opens the door to assumption, provided the original lender is willing to consent and comfortable with the buyer as a new obligor. Even where assumption is available, it is worth comparing against what a fresh refinance would actually cost and require, since inherited terms are not always better than terms negotiated new. Whichever path is used, the outgoing seller should treat obtaining a written release from any personal guarantee as a condition of closing, not an afterthought to be chased down later.
