This paper focuses on the capital restructuring that occurs after M&As in the banking industry with a particular attention on changes in D/E ratios. The main purpose is to assess the impact of those changes on the merged bank entities’ liability, risk and solvency. Acquisitions of any bank company constitute a major part of its action plan, which triggers capital restructuring to overcome the issues of assets acquisition or management of liabilities and market positioning; however, the effect of these restructuring on the D/E ratio is still an unexplored area. Thus, the study aims to address this research question of how the acquiring banks modify their capital structure to achieve the target D/E ratio post-acquisition, and how the change impacts their balance sheet longevity. This research work employs both descriptive and analytical research techniques; drawing data exclusively from secondary sources in form of the financial statements of the banks engaged in the M&As. The appraisal of the case study of Canara Bank with Syndicate Bank can certainly help in offering a clear insight to the financial changes which go on after these amalgamations. This is evidenced by the assessment of post-merger capital restructuring by benchmarking the operational efficiency of the acquired banks’ performances to that of TCC by evaluating major financial parameters such as return on equity (ROE), non–performing loan ratios, and capital adequacy ratios (CAR). This research shows that various post-merger changes in the D/E ratios explain the risk management and financial solvency of the merged firm. Furthermore, the study focuses on the ability of managing these ratios as they are strategic variable in balancing between the high financial leverage and the risks. This work advances the knowledge on financial restructuring in the banking sector and offers important implications for regulators, practitioners, and investment firms regarding the quality of banking M&As over the long term
