The balance of debt and capital in an organization or business is mainly represented by the capital structure. The objective of this research endeavour is to analyse the correlation between capital structure and various factors that impact Indonesian firms operating in the telecommunications subsector, including asset structure, firm size, sales growth, business risk, and free cash flow. Quantitative techniques were used for this study. Purposive sampling was utilized to choose 15 organizations with 75 observation units, and secondary data was gathered from the financial records of those 15 businesses operating in the telecommunications subsector between 2017 and 2021. The data was examined through multiple linear regression analysis. The findings of this study indicate that sales growth does not affect capital structure. Conversely, asset structure exhibits a negative impact on capital structure, while firm size, business risk, and free cash flow have positive effects on capital structure. These findings indicate the significance of comprehending the factors that impact capital structure and the pertinent theories. This understanding can offer valuable insights to companies, helping them make informed decisions and avoid irrational choices that may impact the company or external stakeholders, such as investors.
