Even though the presence of women has increased in the decision-making areas, their impact on corporate performance remains questioned. There are several studies highlighting the positive effects of women in financial and non-financial outcomes such as corporate social responsibility (CSR), while others report inclusive or weak results. This uncertainty reinforces how imperative it is to further examine whether and how women in corporate boards influence organizational performance across industries. To analyze the relationship between gender diversity on corporate boards and corporate performance, this study will focus on financial indicators which includes return on assets (ROA), return on equity (ROE), return on investment (ROI), net profit, and, also, non-financial indicators, including corporate social responsibility (CSR). A quantitative methodology is applied, along with a hypothetical approach by using data obtained from financial statements, annual and sustainability reports from fifteen European multinational companies across different industries throughout a period of ten years (2014-2024). To test whether gender diversity enhances corporate performance, statistical techniques such as regression analysis will be used. It is found that the presence of women on boards is modestly but positively associated with operational efficiency, also a more stable relationship with CSR and sustainability outcomes demonstrates that gender diversity, particularly, women on corporate boards as a significant influence in shaping non-financial dimensions of performance. These findings will contribute to the on-going debate on gender diversity on boards and how corporate performance can be affected.engGender diversityCorporate boardsSustainabilityCorporate social responsibilityFinancial performanceCorporate performancemaster thesis204089220
