What is an Acquisition Premium in an M&A?

An acquisition premium is the difference between the actual price paid to acquire a company and the estimated real value of the acquired company before the acquisition. It is often recorded as "goodwill" on the balance sheet.

How Do You Calculate an Acquisition Premium? (Formula and Example)

The formula for an acquisition premium looks like this:

Acquisition Premium = (Offer for Target Company - Target Company's Actual Worth) / (Target Company's Actual Worth) 

For example, let's assume Company XYZ wants to acquire Company ABC. If Company ABC is worth $15 per share but Company XYZ offers $20 per share, this means Company XYZ is willing to pay a 30% acquisition premium ($20 - $15)/$15.

Although acquisition premiums can run quite high, not every company pays an acquisition premium for a target. Furthermore, not every company intentionally pays an acquisition premium. 

For instance, if Company XYZ offered $20 per share when ABC was trading at $20, but then ABC shares fell to $10 per share before the acquisition was complete, Company XYZ would find itself paying a 50% premium. In most cases, however, this dramatic drop in share price would probably cause Company XYZ to withdraw its offer.

The size of the premium often depends on various factors such as competition within the industry, the presence of other bidders, and the motivations of the buyer and seller. 

Why Do Companies Pay Acquisition Premiums in M&As?

Most companies pay acquisition premiums for two reasons: (1) to ensure that the deal gets closed and (2) because they feel that the synergies generated by the combined entities will be greater than the total price paid for the target. 

The decision of how much to pay for an acquisition target involves professional judgment beyond that which comes from evaluating spreadsheets. After all, even if paying an acquisition premium benefits the target's shareholders, paying a higher acquisition premium puts more pressure on the acquiring company to produce the results its inherited shareholders will expect.
