EnronEnergy company Enron was broken up after revelations of Andersen's performance as an auditor. The Powers Committee (appointed by Enron's board to look into the firm's accounting in October 2001) came to the following assessment: "The evidence available to us suggests that Andersen did not fulfill its professional responsibilities in connection with its audits of Enron’s financial statements, or its obligation to bring to the attention of Enron’s Board (or the Audit and Compliance Committee) concerns about Enron’s internal contracts over the related-party transactions".

It had already started winding down its American operations after the indictment, and many of its accountants joined other firms. The firm sold most of its American operations to KPMG, Deloitte & Touche, Ernst & Young and Grant Thornton LLP. The damage to Andersen's reputation also destroyed the viability of the firm's international practices. Most of them were taken over by the local firms of the other major international accounting firms.
The Andersen indictment also put a spotlight on its faulty audits of other companies, most notably Waste Management, Sunbeam, the Baptist Foundation of Arizona and WorldCom. The subsequent bankruptcy of WorldCom, which quickly surpassed Enron as the biggest bankruptcy
