What is personal guarantee?

For business buyers, a personal guarantee is most frequently encountered when securing Small Business Administration (SBA) loans or other forms of debt financing for an acquisition. Lenders, especially for small and medium-sized businesses (SMBs), often require the principal owners to personally guarantee a portion or all of the business's debt. This reduces the lender's risk by providing an additional layer of security beyond the business's assets, ensuring they can attempt to collect from the owner's personal wealth (e.g., home equity, personal savings) if the business fails to pay.

Founders validating a startup idea or seeking initial funding need to understand that investors, particularly in early-stage debt financing or even some venture debt scenarios, might also request personal guarantees. This signals to lenders or investors that the founder has "skin in the game" and is personally committed to the success of the venture. A common mistake is not fully understanding the implications: a personal guarantee means your personal financial well-being is directly tied to the business's performance, which can be a significant risk for new ventures or heavily leveraged acquisitions.

When evaluating a target business for acquisition, a buyer must thoroughly review existing debt obligations. If a seller's business has existing debt that the buyer intends to assume (which is rare in an asset purchase but common in a stock purchase), or if the buyer is taking out new loans, personal guarantees will likely be a key negotiation point. Buyers should always seek to limit the scope and duration of any personal guarantees, negotiate for a cap on liability, or explore options like partial guarantees where applicable.
