Abstract: Merger and Acquisition played a crucial role in this fastest growing banking sector in India. The government had merged Dena Bank and Vijaya Bank with Bank of Baroda, creating the third-largest bank by loans in the country in 2018. The purpose of the study is to analyze the after-effect of merger of banks on various critical financial ratios, Non-Performing Asset (NPA), credit growth, and share price. The paper also attempts to investigate the implication and challenges of the functioning of the bank after merger. The outcome of analysis indicate that Bank of Baroda, after merger, performed better in nearly all the crucial ratios relating to banking and the bank has improved on the ratios - Profit Margin, Asset Utilization Ratio, Net Interest Margin, Return on Equity, Return on the Asset, Operating Efficiency, and Income Activity Per Employee. Bank of Baroda’s most significant achievement, after the merger, is that it has reduced gross NPA as well as net NPA and the bank has turned profitable.
