This study examines the effect of capital structure and liquidity on profitability before and during the Covid-19 pandemic in telecommunications companies listed on the Indonesian stock exchange. In knowing how much profit a company gets, it can be seen from its financial performance, especially in the capital structure as measured by DER and liquidity as measured by CR. Capital structure will affect profitability as measured by ROE, this is because the maximum use of debt will reduce interest payments because companies are required to pay higher interest.
