Difference between Merger, Acquisition,Taker Over, Reverse Take Over in pharma business

A merger occurs when two separate entities combine forces to create a new, joint organization.
An acquisition refers to the takeover of one entity by another. A new company does not emerge from an acquisition; rather, the smaller company is often consumed and ceases to exist, and its assets become part of the larger company.

Acquisitions also called takeovers. .

Sometimes, however, a smaller firm will acquire management control of a larger or longer established company and keep its name for the combined entity. This is known as a reverse takeover.
