Quality of Earnings vs. Financial Statement Audit: Understanding the Difference

October 20, 2026 | By: The Transactional Services Team

Business owners often assume a financial statement audit and a Quality of Earnings (QoE) analysis provide the same level of insight. While both involve a review of financial information, they serve very different purposes.

A financial statement audit is designed to determine whether historical financial statements are fairly presented in accordance with applicable accounting standards. A Quality of Earnings, or QoE, analysis is more transaction-focused. It evaluates the sustainability and quality of the earnings that drive business value, particularly in the context of a potential sale, acquisition, or financing event.

A common misconception is that a company with audited financial statements does not need a QoE. In reality, most M&A transactions still require a QoE because buyers are trying to understand not only whether the numbers are fairly stated, but also what level of earnings and cash flow is likely to continue after closing.

Both can be valuable, but they are not substitutes for one another.
