What it means
In any sale process there is a seller and there are bidders, and the bidder is always on the buying side. The bidder's core task is to work out what the asset is worth to them specifically, then offer something below that number so there is room left to make a return.
In takeovers the term becomes formal and legal. Once a bidder announces an offer for a listed target it is bound by takeover rules covering the price it may pay, the timetable it must follow and the information it must disclose to shareholders.
Discipline comes from setting a walk-away price before the process starts. A bidder who has written down the highest number that still makes the deal worthwhile is much harder to push past it when a rival appears in the room.
Price is rarely the only thing being judged. Public sector tenders normally score bidders on a weighted combination of cost, technical quality, delivery timetable and past performance, which is why the cheapest bidder does not automatically win the work.
One useful variant is the stalking horse bidder, used in distressed sales. That bidder agrees a floor price for the assets before the wider process opens, which reassures the seller and usually earns the bidder a break fee if someone else eventually wins.
In practice
Real-world examples.
Example
A civil engineering firm is one of six bidders for a council bridge repair contract. It prices the job at $2,800,000, which includes a 9% margin and a $90,000 allowance for bad weather, and it loses to a bidder at $2,450,000 that has made no similar allowance.
Example
A private equity fund becomes the sole bidder for a family owned packaging business after two trade buyers walk away over pension liabilities. With no competition it negotiates the price down from $34,000,000 to $29,500,000 and adds an earn-out tied to the next two years of profit.
Example
An art collector registers as a telephone bidder for a single lot estimated at $120,000 to $160,000. She instructs the auction house not to go above $175,000, and the lot sells to someone else at $210,000, which she treats as a good outcome rather than a defeat.
Formula
Calculation
Bid premium = (offer price per share - undisturbed share price) / undisturbed share price
Total consideration = offer price per share x shares outstanding
A listed engineering group trades at $40.00 per share before any rumour of a deal and has 25,000,000 shares in issue. A bidder announces a cash offer of $58.00 per share, so the premium is ($58.00 - $40.00) / $40.00 = $18.00 / $40.00 = 45%.
The cash the bidder must fund is $58.00 x 25,000,000 = $1,450,000,000, against a pre-bid market value of $40.00 x 25,000,000 = $1,000,000,000. That means the bidder is paying $450,000,000 above the market's own view of the business, and it needs cost savings or performance improvements worth at least that much to leave its own shareholders no worse off.Case study
Seen in the real world.
The following is an illustrative and entirely fictional scenario. Marchbank Industrial, an invented pump manufacturer, decided to bid for Corley Valves, another invented business, and its board set a walk-away price of $46,000,000 built from $41,000,000 of standalone value plus $5,000,000 of realistic cost savings.
A second bidder appeared at $44,000,000 and the process turned competitive within days. Marchbank's chief executive pushed to go higher, arguing that losing would hand a rival a strong position in the same customer base, and the board approved a winning offer of $51,000,000.
Two years later the savings had come in at $3,000,000 rather than $5,000,000, so the honest value of the target was $41,000,000 + $3,000,000 = $44,000,000 against a price of $51,000,000. The fictional board's own review concluded that the $7,000,000 gap was not a valuation error but a discipline failure, because the walk-away price had been set and then quietly abandoned.
Watch out
Common mistakes.
- Setting a walk-away price and then raising it in the heat of the process, which defeats the whole point of having one.
- Assuming the lowest bidder always wins a tender, when quality, delivery and financial standing are usually scored alongside price.
- Treating the bid price as the full cost and forgetting adviser fees, transfer taxes, financing costs and the expense of integrating what you have bought.
Questions
People also ask.
Does the bidder always pay the price they bid?
In a sealed bid or an open ascending auction yes, but some processes use second price rules, and in takeovers the final figure often moves after due diligence.
Can a bidder withdraw an offer?
Usually yes before it is accepted, though auction terms and formal takeover rules can make a bid binding and expensive to abandon.
What is a stalking horse bidder?
A buyer who agrees an opening price for distressed assets to set a floor for the auction, normally in return for a break fee if a higher bid wins.
