The exchange ratio is the number of shares that shareholders of an acquired or merging company will receive in exchange for each share they currently hold — a critical metric in merger, acquisition, and amalgamation transactions that determines the economic value delivered to existing shareholders of the target company. For example, an exchange ratio of 0.75 in a merger means that for every one share held in the target company, the shareholder receives 0.75 shares of the acquiring company. The exchange ratio is determined through negotiation between the boards of the merging entities, supported by independent valuation reports from merchant bankers — and must be approved by shareholders, creditors, and the National Company Law Tribunal (NCLT) in India. The fairness of the exchange ratio is assessed by comparing it to the relative intrinsic values and market prices of both companies. SEBI requires listed Indian companies involved in mergers and amalgamations to provide independent valuer certificates confirming the reasonableness of the exchange ratio. For minority shareholders of the target company, the exchange ratio directly determines whether they receive fair value for their holding — an unfair exchange ratio that benefits the promoter at the expense of public shareholders can trigger SEBI enforcement action and shareholder litigation.
