The Effect of Capital Structure On Company Value with Profitability and Dividend Policy as A Mediating Variable

The theory of capital structure with taxes is put forward by stating that the value of a company increases as the total debt increases. The use of debt in the company's capital structure, on the other hand, also incurs costs that can reduce the value of the company, so    Modigliani and Miller (1963) the trade-off theory reveals that there is a so-called optimal capital structure. This study aims to test and analyze the influence of capital structure, profitability, and dividend policy on company value, both directly and indirectly.
