The Nasdaq website offers income statements for publicly traded companies that detail companies' net profits or net losses. An income statement details the total revenue and operating expenses generated by a company over a specific period of time, typically three months or annually.
A publicly traded company is required to file a quarterly report and an annual report with the Securities and Exchange Commission. These documents include information such as net income, net sales and earnings per share.
A publicly traded company is also required to submit a 10-Q for the first three fiscal quarters and a 10-K annually to the SEC. These documents provide far more details than quarterly and annual reports and provide a wealth of information regarding a company's financial state.
