Demerger

A demerger is when a company splits off a business division into a separate, independently listed company, giving shareholders shares in both.

In a demerger, a diversified company carves out a unit (say, a consumer arm or a financial-services arm) into a new entity. Existing shareholders receive shares of the new company in a set ratio, often unlocking value that was hidden inside the conglomerate.

Indian examples include the demerger of financial-services and other arms by large groups. The parent's share price adjusts downward to reflect the spun-off value, and the new company lists separately on the NSE/BSE. Demergers can sharpen management focus and let investors value each business on its own.
