The COVID-19 economic external shock may have severe consequences for corporate governance. The study looked at the non-financial sector in Bombay and surveyed 120 businesses in the city for the next two years (2019 and 2020). There is no statistically significant difference between the period before and after the COVID-19 epidemic in terms of company performance, governance structure, and dividend, liquidity, or leverage levels. The study also found that larger boards significantly improve company success. By dividing the sample by year, we discovered, however, that board size is irrelevant in the uncertain times of the current crisis, while board diversity appeared to significantly enhance firm performance during the crisis, in contrast to the prior year, when it had an inverse association with firm performance in both indicators. This research demonstrates how the Coronavirus has affected the connection between company success and corporate governance.
