What is an 'Adverse Opinion'
An adverse opinion is a professional opinion made by an auditor indicating that a company's financial statements are misrepresented, misstated, and do not accurately reflect its financial performance and health. Adverse opinions are usually given after an auditor's report, which can be internal or independent of the company.
BREAKING DOWN 'Adverse Opinion'
Adverse opinions are not a good thing for companies because it implies wrongdoing. An adverse opinion is a red flag for investors and can have major negative effects on stock prices. Auditors will usually give a red flag if the financial statements are significantly different from generally accepted accounting principals (GAAP).
