Enron collapsed in 2001 after it was revealed that the company had used fraudulent accounting and off-balance-sheet partnerships to hide debt and inflate profits. It then filed for bankruptcy, and the scandal helped trigger major changes in corporate oversight and accounting rules.

What happened

  • Enron was once a fast-growing energy company that became one of the biggest in the U.S..
  • Executives used complex structures to keep losses off the books and make the company look healthier than it was.
  • When the truth came out, Enron’s stock collapsed, investors lost billions, and thousands of employees lost their jobs.
  • Its auditor, Arthur Andersen, also fell apart after the scandal.

Why it mattered

The Enron scandal became a landmark case of corporate fraud and led to the Sarbanes-Oxley Act, which tightened rules for public-company reporting and auditor independence.

In one line

Enron didn’t just fail as a business; it became one of the most infamous examples of accounting fraud in modern U.S. history.
