Takeover Premium
A takeover premium is how much more an acquirer offers than the target’s market price before the deal. Offering $65 for a stock trading at $50 is a 30% premium.
A takeover premium is the extra amount a buyer offers above a target’s market share price to win control. Premiums encourage shareholders to sell, but a high premium can mean the acquirer overpays.

Takeover premium in plain words
In a tender offer, the bidder usually offers more than the current share price to persuade holders to sell.1
That's why most shareholders welcome tender offers — they're a rare chance to sell above the market price.2
Premium = (offer price − undisturbed share price) ÷ undisturbed share price.
How to evaluate a takeover premium
Find the undisturbed price
Use the price before rumours, not the post-announcement price.
Compare with the offer
Compare the offer with the market price; it is usually higher.1
Compute the percentage
Divide the difference by the undisturbed price.
Judge management’s response
Expect that management may turn down even an offer above today's price, for its own reasons.3
Consider rival bids
Watch for a rival bidder — a “white knight” — which can push the premium higher.3
Beware small offers
Don't assume every offer includes a premium; some smaller ones don't.2
Worked examples
Example 1 — Calculation
30% premiumA hypothetical target trades at $40; a buyer offers $52.
| Undisturbed price | $40 |
| Offer | $52 |
| Premium | 30% |
As usual, the bidder offered more than the market price to encourage holders to sell.1
Example 2 — Rejected bid
Bid rejectedA hypothetical board rejects a 20% premium, expecting more value from its growth plan.
| Premium offered | 20% |
| Board view | Too low |
Management might refuse an offer above the current share price; a buyer who persists makes a hostile takeover attempt.3
Example 3 — No real premium
Below marketA hypothetical mini-tender offers $9.50 when shares trade at $10.
| Market price | $10.00 |
| Offer | $9.50 |
Holders who assumed there was a premium lost out — this offer was actually below market.2
High vs low premium
| Aspect | High premium | Low premium |
|---|---|---|
| Chance of success | Higher | Lower |
| Risk for acquirer | Overpaying | Losing the deal |
| Target holders | Large gain | Small gain |
| Market reaction | Acquirer shares may fall | Rival bids possible |

Purpose
Beginner
The premium is there to persuade shareholders to sell.1
Hostile bids
Intermediate
If the bidder keeps going despite management's objections, the bid becomes hostile, and the target may look for a friendlier buyer — a “white knight”.3
Investor caution
Advanced
Some offers, especially small ones, carry no premium at all.2 Takeover law differs by country, so check local rules.
Common mistakes
Using the post-rumour price

Ignoring payment form
Shares and cash differ.
Assuming every offer has a premium
Mini-tenders may not.
