Essential M&A Concepts
What Does Acquisition Mean in Business?
An acquisition is a transaction where one company purchases another company or its assets. The acquiring company gains control of the target's operations, employees, customers, and intellectual property.
Types of Acquisitions:
- • Friendly: Negotiated between buyer and seller
- • Hostile: Against target management's wishes
- • Asset purchase: Specific assets acquired
- • Stock purchase: Entire company acquired
Why Companies Acquire:
- • Gain market share or customers
- • Acquire technology or talent
- • Enter new markets or geographies
- • Achieve economies of scale
What Is the Difference Between a Merger and an Acquisition?
While often used interchangeably, mergers and acquisitions have distinct legal and structural differences:
| Characteristic | Merger | Acquisition |
|---|---|---|
| Structure | Two companies combine into one new entity | One company purchases another |
| Identity | Both companies may lose original identity | Acquirer retains identity; target absorbed |
| Power Dynamic | Theoretically equal partnership | Clear buyer and seller roles |
| Consideration | Typically stock-for-stock | Cash, stock, or combination |
| Reality | Most "mergers of equals" have a dominant party-true mergers are rare | |
