Enron was an energy company that collapsed in 2001 due to widespread corporate fraud and corruption. The company used accounting loopholes and undisclosed transactions to hide billions in debt and inflate profits. When these activities came to light, Enron's stock price plummeted and the company declared bankruptcy. Key executives were found to have knowingly misled regulators and conducted illegal insider trading, resulting in total losses estimated at $74 billion for shareholders and employees. The Enron scandal exposed flaws in financial oversight and eroded public trust in corporations.
