The primary difference between mergers and acquisitions is that a merger is the combining of two organizations into an entirely new entity, while an acquisition is when a company absorbs another, but no new organization is created.

For instance, if two companies agree to merge and create a new legal entity, that would be a merger. On the other hand, if one company buys out another and absorbs it into itself without changing its own identity, that would be an acquisition.
