Merger & Amalgamation

A merger (amalgamation) combines two companies into one, with shareholders of the company being absorbed receiving shares of the surviving company in a fixed swap ratio (for example, 10 shares of A for every 7 of B). The swap ratio is the single number that decides who wins the deal.

Listed-company mergers in India run through a scheme of arrangement: board approval, stock-exchange and SEBI vetting, shareholder and creditor meetings (where a majority of minority shareholders matters), and finally NCLT sanction. The process routinely takes a year or more, so the market prices the probability of completion, not just the announced terms.

For shareholders, everything hangs on the swap ratio and what backs it — independent valuation reports and a fairness opinion accompany the scheme. A ratio favourable to promoters of one side at minority shareholders' expense is the classic governance red flag, and institutional investors and proxy advisors increasingly vote such schemes down.

Check the strategic logic (does the combination cut costs or just complexity?), pro-forma debt, and what happens to your holding mechanically: on the record date your old shares are extinguished and new shares credited per the ratio, with cost basis carried over for tax.

How stocks tend to react

Reactions split by side and by terms: the company being acquired often moves toward the value implied by the swap ratio, while the acquirer can fall if the market thinks it overpaid. Wide gaps between market price and implied deal value usually reflect doubt that the scheme will complete on announced terms.

MarketPing measures this instead of guessing: every analysed announcement carries the stock's actual price reaction across 14 horizons, and the Reaction Lab aggregates how each category of announcement has historically moved stocks.
