Sell-side auction

A company can be sold in two ways. It can be sold to one buyer who asked. Or it can be sold by running a race between several buyers at once. The second way is called an auction, and it is how most large businesses change hands.

It is not an auction in the way a house sale is. Nobody stands in a room shouting numbers. Instead the seller sets the rules: who gets to look, what they get to see, and by when they must say what they will pay. Bidders who break the rules are dropped.

The point of all this is simple. A buyer who knows there is another buyer pays more. That is the whole product. The seller's adviser is not paid to know what the business is worth — a model can do that. The adviser is paid to make sure at least two people still want it on the last day.

The race has two rounds. In the first, a wide group sees a little and gives a rough number. In the second, a short list sees a lot and gives a real one. Each round trades more information for more commitment, and each round is a chance to drop the people who are not serious.

The two rounds, and why there are two

A first round is deliberately cheap for a bidder to enter. A teaser of one page without the company's name, a non-disclosure agreement, then an information memorandum. What comes back is a non-binding indication: a range, some assumptions, and a description of how the bidder would fund it. It costs a bidder a few weeks of work, which is why twenty parties can be asked without anybody wasting a fortune.

The second round is expensive. The shortlist gets the data room, management meetings, its own diligence teams and the seller's draft contract to mark up. Running eight parties through that is unmanageable and unfair; running two is not competitive. Four to six is the usual answer.

The process letter is the rulebook

• What a bid must contain — price, funding evidence, the mark-up, the approvals needed and how long they take.
• When it is due — to the hour, because bids that arrive after the deadline give the seller a problem it did not want.
• What the seller reserves — usually the right to change the rules, negotiate with anybody, or stop entirely. A process letter binds bidders and not the seller.

Three things bidders compete on besides price

• Certainty. A bid with committed financing and few conditions can beat a higher one that might not complete. See leveraged finance for why a financial buyer's certainty is bought rather than assumed.
• The contract. A bidder that accepts the seller's draft nearly unchanged is offering the seller weeks of its life back, and a lower risk of a claim afterwards.
• Speed. Every extra month is a month in which the market, the business or the buyer can change.

Vendor diligence

Rather than let each bidder discover the same problems separately, the seller commissions its own reports and gives them to everybody. It saves time, it standardises what bidders know, and it removes one common excuse for a late price cut. It also puts the seller's adviser in the position of having written the document a buyer will later say it relied on, which is why those reports carry careful language about who may rely on them.

Why a process is worth more than a bilateral talk

A bilateral negotiation has one buyer, and that buyer knows it. The seller's only leverage is the threat of not selling, which is credible only if the standalone plan is genuinely fundable. An auction replaces that with a much stronger threat: sell to somebody else on Tuesday.

The cost is real. A process leaks; a leak reaches customers, staff and competitors. It takes months, during which management is doing two jobs. And a failed auction is public in a way a failed conversation is not — a business that was on the market and did not sell is harder to sell next year. Sellers weigh those costs against the price uplift, which is why some large businesses are sold bilaterally on purpose.

Where the price actually moves

• Between the indication and the binding bid. First-round numbers are cheap and usually optimistic. What survives contact with the data room is the real bid, and it is normally lower.
• In the last week. With two bidders left and a deadline, the seller can run a final round. This is where the last increment comes from, and it exists only because the second bidder is still there.
• After signing, quietly. Completion accounts adjust the price for the cash, debt and working capital actually present on the closing day. A headline number is not what is paid.

The structural conflict, stated plainly

The sell-side adviser is usually paid a percentage of the value achieved and nothing at all if the board decides not to sell. That is an incentive to complete a transaction, which is not the same as an incentive to get the best outcome for the owner. It is disclosed, it is universal, and it is a structure rather than an accusation about any firm. The counterweights are the board's own duty, the presence of a second adviser on large deals, and — where shareholders vote — a fairness opinion from somebody paid a flat fee.

What the process cannot fix

An auction manufactures competition; it cannot manufacture buyers. In a sector where three plausible acquirers exist and two are barred by competition law, the process letter is theatre. Good advisers say so, and the honest version of the advice is sometimes to wait or to sell bilaterally rather than run a race that everybody can see has one runner.

The formulas above are standard textbook formulations, simplified for teaching. They explain the mechanism — they are not a valuation tool, and they will not reproduce a dealer’s price.
