The paper aims to investigate the role of liquidity Ratio, Profitability, and Company Size on Coal Company Value by using Capital Structure as an intervening factor during the 2017-2022 period. The population of this study are coal mining sub-sector companies listed on the Indonesia Stock Exchange during the 2017-2022 period. A total of 8 national coal companies were selected based on criteria using a purposive sample technique. The findings indicated that Size, Profitability, and Liquidity all had a detrimental impact on Capital Structure. The second finding is that Profitability and Capital Structure have a favourable impact on firm value whereas Liquidity and Size have a negative impact. In the coal sub-sector companies listed on the IDX in 2017–2022, the factors of liquidity, profitability, and size have an overall influence on company value through capital structure as an intervening variable.
