Privately held businesses are not always contained neatly within one legal entity. The operating company may lease property from another entity owned by the seller. Employees may be shared. Administrative expenses may be paid by an affiliated company. Vehicles may be owned personally. Intellectual property may sit elsewhere. Purchases may flow through a related entity, and management fees may move earnings between companies.

If the analysis focuses only on the entity being sold, the financial picture may be incomplete. A Quality of Earnings review should identify related entities and understand the economic relationships among them. What expenses will continue after closing? What services are currently being provided without charge? What assets are actually transferring? What contracts belong to another entity? What costs will the buyer have to recreate?

Related-party activity does not necessarily mean there is a problem. But it does mean the historical financial statements may require normalization to reflect the business on a stand-alone basis.
