This study examines the cash flow profiles of firms listed in the Borsa Istanbul (BIST) Corporate Governance Index within the framework of the "Cash Flow Activities Model." The model provides a structured approach to analyzing how firms balance cash flows from operating activities with investment and financing activities, offering insights into their financial health. The study evaluates financial data from 2010 to 2023, categorizing firms into eight distinct cash flow models. The findings reveal that a significant portion of firms in the BIST Corporate Governance Index align with the "Successful Firm" model, indicating strong financial management practices. However, some firms have transitioned between different cash flow profiles over time, signaling financial distress in certain periods. These results provide valuable insights for investors, financial analysts, and corporate managers, highlighting the influence of corporate governance principles on firms' cash flow dynamics.
