M&A (Mergers and Acquisitions) is the corporate world's way of growing, consolidating, or transforming businesses. A merger combines two companies into one new entity (equals coming together). An acquisition is one company buying and absorbing another (buyer and target).
Famous deals: Disney acquired 21st Century Fox for $71.3 billion (2019), Microsoft bought Activision Blizzard for $69 billion (2023), and Tata Steel acquired Corus for $12 billion (2007). These mega-deals reshape entire industries.
Global M&A activity typically exceeds $3-4 trillion annually. Investment banks earn massive fees (1-3% of deal value) for advising on M&A. The process involves valuation, due diligence, negotiation, regulatory approval, and integration. Studies show 60-70% of acquisitions fail to create expected value — usually due to cultural clashes and integration challenges.
