The sample in this study consisted of 15 companies selected through purposive sampling techniques, with secondary data in the form of annual financial reports for five years. The results of the study indicate that: 1) company size has a negative and insignificant effect on financial performance; 2) company size has a negative and significant effect on profitability; 3) profitability has a positive and significant effect on financial performance; and 4) profitability mediates the relationship between company size and financial performance.
