This study analyzes the impact of the amalgamation of Oriental Bank of Commerce and United Bank of India with Punjab National Bank on its financial performance. The research focuses on comparing the pre- and post-amalgamation periods using important financial indicators such as Return on Assets (ROA), Return on Equity (ROE), Net Interest Margin (NIM), Gross NPAs, Net NPAs, and Provision for NPAs. Secondary data were collected from published financial statements, and statistical tools such as Independent Sample t-test and Pearson correlation were applied to examine the significance of differences and the relationship between asset quality and profitability. The pre-amalgamation analysis revealed that the banks were experiencing financial stress due to rising non-performing assets, declining profitability, and increased provisioning requirements. The post-amalgamation findings indicate a significant improvement in the financial health of Punjab National Bank. Asset quality strengthened as both Gross and Net NPAs declined, while higher provisioning enhanced the bank’s ability to absorb potential losses. Profitability ratios such as ROA and ROE showed noticeable recovery, demonstrating improved efficiency in utilizing assets and shareholder funds, although Net Interest Margin remained relatively stable. Correlation results further confirmed that better asset quality contributes directly to higher profitability. Overall, the study concludes that the merger positively influenced the bank’s stability, operational performance, and long-term sustainability, highlighting the strategic importance of consolidation in the Indian banking sector.
