This study examines the multifaceted impact of the global mergers and acquisitions (M&A) strategy executed by Vodafone Group Plc over the past three decades. Focusing on the evolution of corporate consolidation in the telecommunications sector, the study utilizes Economic Value Added (EVA) to evaluate the effect of these strategic maneuvers on long-term shareholder value creation. Mergers and acquisitions have been Vodafone's primary strategic tool to achieve unprecedented business growth, secure operational efficiency, and establish a formidable competitive advantage across Europe, Asia, and Africa. The study covers a comprehensive longitudinal period, analysing key pre- and post-merger data surrounding monumental deals such as the acquisition of Mannesmann (2000), Hutchison Essar (2007), Kabel Deutschland (2013), and the strategic merger with Idea Cellular in India (2018). EVA is utilized as the paramount financial performance metric to assess Vodafone's ability to generate returns surpassing its towering cost of capital, especially given the premium valuations paid during telecom booms. The research relies heavily on secondary data meticulously extracted from Vodafone’s annual reports, SEC filings, financial databases, and academic publications. Through advanced descriptive statistics, trend analyses, and paired sample t-tests, the study contrasts EVA metrics across different merger epochs. The findings elucidate the complex reality of cross-border telecom consolidation: while early acquisitions vastly expanded global footprint and revenue, the massive capital charges associated with these deals often exerted severe downward pressure on short-to-medium-term EVA. Conversely, recent synergistic mergers have demonstrated a stabilization in value creation. This study provides profound insights for investors, financial analysts, corporate strategists, and telecommunications researchers regarding the efficacy of M&A in fostering genuine economic wealth.
