What opinion is issued if the external auditor does not find any problems with the way a firm prepares and reports its financial statements?

If an external auditor does not find any problems with a firm's financial statements, they typically issue an "unqualified opinion" or "clean opinion." This opinion indicates that the financial statements are presented fairly, in all material respects, in accordance with the applicable financial reporting framework. It signifies that the auditor believes the statements are free from significant misstatements or discrepancies.
