This study is basically the impact of corporate finance on the firm performance. Two major pillars of the corporate finance are capital structure and dividend policy which play vital role for long term financial success of a firm. We investigate the influence of financial policies such as capital structure and dividend policy on firm sustainable performance. The study also captures the role of COVID-19 as control variable in influencing the sustainable performance. The analysis is done on panel data of 150 non-financial firms listed on Pakistan Stock Exchange from 2010 to 2023. Our findings show that capital structure has significant and negative effect on sustainable performance, while there is positive correlation between dividend policy and firm sustainable performance.
