GAAP

A standardized set of accounting rules and standards used to compile, present, and report financial statements.

Generally Accepted Accounting Principles (GAAP) are the standardized rules, regulations, and concepts that public companies in the United States must follow when compiling and presenting their financial statements. Established by the Financial Accounting Standards Board (FASB), GAAP ensures consistency, comparability, and transparency across different companies and industries, making it easier for investors to analyze financial performance. For investors, GAAP metrics serve as the official, regulated baseline for assessing a company's financial health. Because management teams often present customized "non-GAAP" metrics that exclude certain expenses, the GAAP figures provide an objective anchor. Comparing GAAP and non-GAAP figures helps investors identify where a company might be minimizing real costs, such as stock-based compensation, restructuring charges, or acquisition expenses. While GAAP provides a highly standardized framework, it is not without pitfalls. GAAP relies on accrual accounting, meaning revenue and expenses are recognized when they are incurred, not necessarily when cash changes hands. Consequently, a company can show strong GAAP net income while experiencing a severe cash shortage. Investors must look beyond GAAP earnings to cash flow statements to understand a business's true liquidity.

Company A reports a GAAP Net Income of $100 million. However, it also reports a Non-GAAP Net Income of $150 million by excluding $40 million in stock-based compensation and $10 million in acquisition-related restructuring charges ($100 million GAAP + $40 million + $10 million = $150 million Non-GAAP).
