One more credible bidder can raise a client's sale price more than a negotiating tactic because the buyer's fear of losing the deal changes its calculation. An attorney negotiating with a single buyer can only persuade; an attorney running a process with several buyers lets competition inform the number. Under the standard assumptions described by Jeremy Bulow and Paul Klemperer, an auction with one additional bidder can outperform an optimally structured negotiation with fewer bidders, even when the auction gives up seller bargaining power [1] [2]. For an M&A attorney, the practical implication is conditional: adding a qualified buyer may create more value than sharpening counterarguments for the buyer already at the table.
What a single buyer knows that the client does not
When a client negotiates with one buyer, the buyer holds the most valuable piece of information in the deal: that it is alone. A sophisticated buyer does not need to be told this. It infers it from the absence of a process, from the client's willingness to engage on the buyer's timeline, and from the fact that the owner is responding personally rather than through a structured channel. Every term the buyer proposes is calibrated to that inference. The price is set at what the buyer believes the owner will accept, not necessarily at what the business is worth to the buyer.
The attorney can push back on specific terms, and should. But pushback on price from a seller with no alternative is a weak position, and experienced buyers understand that. The buyer’s response to “my client expects more” may be a modest increase paired with a reminder that the buyer has other opportunities. The owner, who does not have other opportunities, may concede. The attorney can negotiate carefully and the client can still leave value on the table because the structure of the situation limits what negotiation can achieve.
Why the second bidder changes the first bidder's behavior
The moment a second credible buyer enters, the first buyer's calculation changes. It no longer prices only against what the owner will accept; it prices against what the other buyer might pay. Since it cannot see the other buyer's number, it may bid closer to its own valuation to improve its chance of winning. The attorney has not said anything different. The buyer is responding to the possibility of loss.
This effect can be strongest when the bidders are of different types. A private equity sponsor bidding against another sponsor may focus on a market multiple. A sponsor bidding against a strategic buyer that may have synergies cannot know the strategic buyer's ceiling and may stretch. A strategic buyer that learns financial buyers are in the process cannot assume it will win on reputation and may put more of its synergy value in the offer. The attorney who builds a list with a mix of buyer types can create this uncertainty on more than one side.
The practical rule is that the client does not need a dozen bidders. The client needs enough credible, engaged bidders that no single one can be confident it is alone. Three or four IOIs from buyers who have requested the data room and attended a management meeting may be sufficient in a particular process, but that is a process judgment, not a general result. One letter and one conversation do not establish meaningful competition.
What the theory says and what it means for process design
The auction-theory result is narrower than a guarantee about any private-company sale. Bulow and Klemperer compare an auction with one additional bidder to an optimally structured negotiation with one fewer bidder. Under their stated assumptions, the auction produces higher expected seller revenue, and the paper describes the value of negotiating skill as small relative to additional competition [1] [2]. The result does not establish that every additional contact will raise a price or that an auction is right for every client.
For process design, this supports spending marginal effort widening the field before the IOI deadline, rather than spending all of that effort preparing for a bilateral negotiation afterward. In the marketing phase, the associate can keep sending teasers and following up with additional qualified buyers after first-tier interest is confirmed. In the offers phase, the attorney can set an IOI deadline so interested buyers submit on a comparable timetable and understand that others are participating. In the negotiation phase, the attorney can keep a credible alternative bidder warm through exclusivity, subject to the client’s instructions and the process terms, because an alternative can strengthen the client’s position when the purchase agreement is negotiated.
None of this requires the attorney to be a better negotiator than the buyer’s counsel. It requires the attorney to run a process that gives each buyer a reason to bid competitively.
The negotiation still matters, but later and on different terms
The claim is not that negotiation is useless. It is that negotiation is most effective when it follows competition rather than substitutes for it. Once the process has produced a price, the attorney's negotiating skill applies to the structure: the working capital peg, the earnout mechanics, the indemnity cap, the non-compete scope, and the escrow release schedule. These terms can change the client's realized value by meaningful amounts, and they are where a careful attorney earns the fee.
But the attorney who tries to negotiate price up from a single inbound letter is working on a harder variable. The price has already been anchored by the buyer's knowledge that it is alone, and argument may not move it far. The sequence that often makes more sense is competition first, to inform the price, and negotiation second, to protect it.
Explaining this to a client who has a letter in hand
The hardest conversation is with an owner who has a letter from a buyer at a number that sounds large and who does not want to risk the opportunity by running a process. The attorney can make the auction-theory point without jargon. The buyer wrote that number knowing it was the only one. If the buyer learned tomorrow that two other qualified buyers were reviewing the same company, would the number go up or down? The owner knows the answer, although the answer is not a promise about the result.
The attorney can then describe what a process costs the owner: a few months, the attorney's time at hourly or fixed rates, and some management attention. Against that, the attorney can describe what one additional serious bidder might do, which is force the first buyer to improve its offer or reveal that it was never going to pay more. Either outcome is information the owner needs. A client with $5 million of EBITDA who gets a second bidder to the table has created a more competitive test of price, but the figure is illustrative, not a measured outcome.
The thing to do this week
Pick a client who has told you about an inbound approach. Before you respond to the buyer on the client's behalf, build a short list of five buyers that appear to have completed comparable deals and ask the client whether the client would be willing to let three of them see a blind teaser. The attorney should verify the buyers' fit and acquisition history before sharing information. If the client says yes, you have begun a process. If the client says no, you have at least made clear that the first buyer's number was set in the absence of competition.
How Acquivo Pro fits
Acquivo Pro gives the attorney a way to organize more bidder work without assuming that the software performs the outreach or makes the decisions. The platform builds a prospect list using the client's data room, website, and questionnaire, and it supports tailored buyer matching. The firm can generate a blind teaser and CIM from the same materials and manage NDA, IOI, and LOI flow in one pipeline, so the attorney and client can decide which names to approve and which contacts to make. Software prepares, organizes, matches, and tracks; the attorney and the client decide and act. To walk through a process on a client you have in mind, request a demo through the Contact page.
Key Points
- A buyer that knows it is the only bidder may price a company at what the owner will accept rather than at the buyer's full valuation.
- Under the standard assumptions of the Bulow-Klemperer result, an auction with one more bidder can outperform an optimally structured negotiation with fewer bidders [1] [2].
- Three or four engaged bidders submitting IOIs on a comparable deadline may be enough in a particular process to prevent any single buyer from assuming it is alone, but the attorney must assess the facts.
- An M&A attorney's negotiating skill is most valuable on structure terms after competition has informed the price, not as a substitute for competition in a bilateral deal.
- An attorney who responds to an inbound letter by evaluating and adding qualified buyers may do more for the client's price than a reply to the letter alone.
