Merger & Acquisition: Meaning, Definition & Indian Stock Market Examples
Consolidation of companies through purchase or combination.
What is Merger & Acquisition?
A Merger combines two companies into one (merger of equals) while an Acquisition (takeover) is when one company purchases another. M&A can create value through synergies (cost savings, revenue expansion) or destroy value through overpayment and integration failures. India's M&A market has grown significantly with dealmaking across tech, pharma, and financial services.
Merger & Acquisition — Indian Stock Market Example
HDFC Bank's merger with HDFC Ltd (2023) was India's largest ever, creating a combined entity with ₹17+ lakh crore in assets. Tata Group's acquisition of Air India (2022) was a landmark revival. Reliance Industries has made dozens of strategic acquisitions (Jio Platforms, Hamleys, Clovia) to diversify its portfolio.

Analyse with OrionFrequently Asked Questions about Merger & Acquisition
How do I evaluate if an M&A deal creates or destroys value?
Key questions: (1) Acquisition price vs intrinsic value — is the buyer overpaying? (2) Strategic rationale — do the businesses actually complement each other? (3) Integration risk — can both cultures merge? (4) EPS dilution — if paid in shares, does dilution outweigh synergies? History shows 50–70% of acquisitions fail to create synergies, often destroying acquirer value.
What is an open offer in India?
When an acquirer crosses 25% shareholding in a listed company, SEBI's Takeover Code requires a mandatory open offer to buy at least 26% more from public shareholders at a fair offer price. This protects minority shareholders during takeovers. The acquirer cannot acquire beyond 25% without making this open offer.
