In the modern business, organizations that recognize the value of intellectual resources and incorporate them into their business strategy have a greater chance of long-term success. Through continuous learning, employee development and establishing strong relationships, organizations can improve their competitive position in the market. In this regard, the aim of the paper is to examine the impact of intellectual capital, i.e., its components of human, structural and relational capital, on ROA as a significant indicator of financial performance. For the preparation of the paper, secondary data were used, which were processed with the help of the VAIC method, and then the obtained results were further analyzed using the IBM SPSS program. HCE was found to affect ROA, while SCE and CEE did not. The results of this research contribute to companies to adequately create a business strategy that contains an incorporated ratio of intellectual capital components, with an emphasis on human capital, which is the basis for the success and progress of organizations in the knowledge economy.
