How Should Sellers Handle a Bidder's Request to Partner with Another Buyer?

Start by identifying what the proposed partnership actually is

A bidder may describe the request as a partnership, consortium, joint bid, co-investment, or temporary teaming arrangement. Those labels do not tell you enough. Ask for a short written explanation of the proposed structure before treating the request as approved. It should identify the participating buyers, the target ownership percentages or economic interests, the proposed lead or controlling party, each participant's role, and whether the arrangement is intended to last only through bidding or continue after closing.

The core question is whether the buyers are combining complementary resources for a defined acquisition or whether they are using the process to coordinate with a potential competitor. A buyer might need another party's operating expertise, financing capacity, geographic reach, or industry knowledge. That can be a legitimate commercial rationale, but it does not remove the need to test how the arrangement affects independent decision-making. The FTC explains that competitor collaborations can be procompetitive, yet risk increases when participants no longer act independently or gain the ability to exercise market power together. [1]

Check funding responsibility and who can make decisions

Do not accept a joint bid based only on the name of a well-known participant. Request evidence of each party's intended funding responsibility, subject to appropriate confidentiality protections. Clarify whether funds will be committed by each buyer, a newly formed acquisition vehicle, a lender, or a combination. The seller should know who is expected to provide equity, who bears fees and expenses, whether financing is conditional, and what happens if one participant withdraws.

Decision rights matter just as much as funding. Ask who can revise the offer, approve diligence requests, sign a letter of intent, authorize exclusivity, and decide whether to proceed. Require a clear explanation of whether one participant can bind the others. If there is a new vehicle, identify its authorized signatory and the relationship between that vehicle and its owners. These questions are commercial diligence, not a substitute for legal or financial advice. They help prevent the seller from spending time with a group that has no agreed authority to deliver a credible offer.

Set confidentiality and information-sharing boundaries before disclosure

A consortium request can change the confidentiality risk because information may move from one prospective buyer to several organizations. Confirm who may receive the seller's materials, whether advisers and financing sources are included, and whether information can be shared with affiliates or portfolio companies. The confidentiality agreement should describe permitted recipients, use restrictions, return or destruction obligations, and the process for reporting an unauthorized disclosure. Counsel should adapt the language to the transaction and applicable law.

Use a staged disclosure plan. Start with information needed to evaluate fit and funding. Move to more detailed operational, customer, supplier, employee, and pricing information only after the parties have demonstrated a serious purpose and the seller has decided that access is appropriate. Keep a record of which participant received each category of material. A data room permission matrix can identify the accountable seller-side owner, the approved buyer-side recipients, and the date on which access ends.

The FTC and DOJ collaboration guidelines state that information about price, output, costs, strategic planning, current operations, and future plans may raise more concern when shared among competitors than historical or aggregated information. The guidelines also discuss limiting access to certain individuals or using an independent third party to handle sensitive negotiations. [2] This is a reason to seek jurisdiction-specific counsel, not a conclusion that any particular disclosure is unlawful.

Ask whether the participants may still compete independently

Before consenting, ask each participant to explain whether it was already considering a separate bid and whether it remains free to do so. The seller should avoid encouraging the buyers to exchange their separate valuation views, walk-away points, financing limits, or bidding strategy. If two possible buyers decide to submit one offer, the seller can evaluate that offer, but should not facilitate a conversation about which party would have won, what price either would have paid alone, or whether one will stand aside in another process.

The distinction is practical. A buyer group that combines resources for one defined acquisition may present a single proposal with a coherent rationale. A group that agrees in advance who will bid, who will sit out, or how losing parties will be compensated creates a different concern. FTC guidance says coordination among bidders can undermine competitive bidding and can be illegal, including arrangements involving a joint venture formed to submit a single bid when the structure is used to prevent competing bids. [3] The facts and applicable law control, so qualified counsel should review the proposal before the seller encourages or accepts coordination.

Use a consistent process for the joint bid and other buyers

A seller can preserve process integrity by giving the consortium the same written instructions provided to other bidders, while requiring any additional information needed to understand its structure. Set the same response deadlines where practical. Ask for one clearly identified offer, the proposed buyer entity, conditions, sources and uses of funds, diligence requests, and the names of people authorized to communicate. If the group wants special access or a different timetable, record the business reason and obtain internal approval.

Do not assume that a larger group deserves preference because it appears to have more resources. Compare the proposal using the seller's stated criteria, which may include price, certainty of funds, closing conditions, regulatory risk, transition capability, and treatment of employees or customers. If a consortium is selected for exclusivity, put the scope and duration in writing and reserve the right to end discussions if funding, authority, confidentiality, or legal conditions are not satisfied.

Build stopping conditions into the review

A good review has explicit points at which access or discussions stop. Examples include a participant refusing to identify its role, inability to explain funding responsibility, inconsistent statements about control, requests for another bidder's confidential information, pressure to share sensitive seller data before signing protections, or a proposed arrangement that appears designed to eliminate independent bids. The seller can pause the process while counsel assesses the issue rather than treating momentum as a reason to continue.

Assign a human owner for each decision. One person should control the approved recipient list and data-room permissions. Another should record the commercial evaluation and open questions. Qualified counsel should own legal conclusions and advise on antitrust, confidentiality, foreign investment, sector regulation, and other applicable issues. A finance professional can test funding evidence and transaction mechanics where needed. Software can organize records and reminders, but it should not approve disclosure, negotiate terms, or decide that a risk is acceptable without human review.

Document the consent decision without overpromising

Keep a concise decision record stating what the seller was asked to approve, which entities and individuals were covered, what information could be shared, which safeguards applied, and who approved the next step. Note unresolved questions and the date for revisiting them. If the seller declines, a neutral response can say that the proposed structure requires further review or does not fit the process. There is no need to accuse a buyer of unlawful conduct when the facts are incomplete.

If the seller proceeds, monitor whether the actual conduct matches the approved structure. A buyer added later, a new affiliate receiving materials, a change in control rights, or a request for broader information can require a fresh review. Consent to a limited diligence step is not blanket consent to every future disclosure. The seller should preserve the ability to narrow access, pause the process, or require revised documents.

Use software to support a human-controlled workflow

A practical workflow can use software to maintain the buyer record, store the proposed consortium structure, assign review tasks, record source documents, and apply permissions that reflect the approved access plan. The accountable seller or adviser should verify each buyer's identity, role, funding explanation, confidentiality status, and decision authority against the underlying records. A reviewer should check for duplicate entities, inconsistent ownership descriptions, missing signatures, and access that exceeds the approved scope.

Run a small trial with non-sensitive or already approved materials before expanding access. Stop the trial if the permission log is incomplete, the source record cannot be traced, a participant receives material outside its approved role, or reviewers cannot explain who made a decision. Keep a human in the loop for every disclosure, consent decision, and change to the bidding process.
