This study examines the impact of strategic mergers and acquisitions (M&A) undertaken by the Tata Group on Economic Value Added (EVA) to evaluate their effect on shareholder value creation. Mergers and acquisitions are widely used as strategic tools to achieve business growth, operational efficiency, and competitive advantage. The study covers a six-year period, focusing on three years prior to a major consolidation (FY2019-20 to FY2021-22) and three years’ post-consolidation (FY2022-23 to FY2024-25). EVA is utilized as the primary financial performance metric to assess the conglomerate's ability to generate returns above its cost of capital. The research relies on secondary data sourced from annual reports, financial statements, company publications, and financial databases. Descriptive statistics and a paired sample t-test are employed to compare the pre- and post-M&A Economic Value Added. The findings aim to indicate whether these strategic expansions improved economic performance and enhanced true shareholder value. This study provides critical insights for investors, financial analysts, corporate managers, and researchers regarding the effectiveness of M&A within large Indian conglomerates.
