Mergers and acquisitions (M&A) have emerged as an important corporate strategy for enhancing business growth, improving competitiveness, and maximizing corporate value. This study evaluates the effectiveness of mergers and acquisitions in creating corporate value among selected Indian companies across the Banking & Financial Services, Information Technology, Pharmaceuticals, Infrastructure, and FMCG sectors during the period 2021–2025. The research adopts a descriptive and analytical approach based on secondary data collected from annual reports, financial statements, SEBI, RBI, MCA, and industry reports published by EY, Deloitte, and KPMG. The analysis focuses on strategic, financial, and operational outcomes of major M&A transactions. The findings indicate that successful mergers and acquisitions improve market share, operational efficiency, profitability, innovation, and shareholder wealth when supported by effective due diligence and post-merger integration. The study concludes that strategically planned mergers and acquisitions play a significant role in maximizing corporate value and achieving sustainable long-term growth in the Indian corporate sector.
