Form 10-Q is a quarterly report that publicly traded companies in the United States must file with the Securities and Exchange Commission (SEC). It provides a comprehensive overview of a company's financial performance, including income statements, balance sheets, and cash flow statements for the quarter. The Form 10-Q also includes management's discussion and analysis, which offers insights into the company's operations and any significant changes or risks. Unlike the annual Form 10-K, the 10-Q is less detailed but is crucial for investors to monitor a company's ongoing financial health throughout the year.
