Closing and Post-Closing: How the Transaction Gets Executed and What Happens After Funds Transfer

By Hank FasthoffJuly 6, 2026

Closing is the moment when ownership changes hands. Money transfers from the buyer to the seller, documents are executed and delivered, and the business becomes the buyer's. Closing is a coordinated exchange of documents, funds, and filings that requires every pre-closing condition to be satisfied, every deliverable to be prepared and signed, and every wire transfer to be initiated and confirmed before the transaction is complete.

Most private company M&A closings happen electronically. Documents are signed via DocuSign or wet-ink counterparts sent by overnight delivery. Funds are transferred by wire. The closing "meeting" is a phone call or video conference during which counsel for both sides confirm that all conditions have been met, all documents have been delivered, and all funds have been wired. In-person closings still occur for transactions involving real property transfers or other documents that require notarization, but the majority of middle-market deals close remotely.

What happens before closing (conditions that must be satisfied), during closing (deliverables that must be exchanged), and after closing (obligations that persist) are all governed by the purchase agreement, and each phase deserves the same attention as the business terms.

Simultaneous Sign-and-Close Versus Deferred Closing

In a simultaneous sign-and-close, the parties sign the purchase agreement and close the transaction at the same time. There's no interim period between signing and closing, which means there are no bring-down conditions, no pre-closing covenants, and no risk of the business deteriorating between signing and the transfer of ownership. Simultaneous closings are possible when no regulatory approvals are required, financing is already in place, all third-party consents have been obtained, and both parties are ready to proceed.

In a deferred closing, the parties sign the purchase agreement on one date and close on a later date (typically 30 to 90 days later). Deferred closings are necessary when regulatory approvals must be obtained (Hart-Scott-Rodino antitrust filing, industry-specific licenses), financing needs to be finalized, third-party consents haven't been secured, or the parties need time to complete pre-closing covenants (transferring permits, preparing transition plans, or winding down specific operations).

Most private company M&A transactions use deferred closings, because at least some conditions can't be satisfied at the time of signing. Deferred closings introduce interim risk (the business could deteriorate, a key customer could leave, or a material event could occur between signing and closing), which is managed through pre-closing conditions, covenants governing the seller's conduct during the interim period, and material adverse effect (MAE) provisions that give the buyer a walk-away right if something fundamental changes.

Pre-Closing Conditions

Pre-closing conditions are the requirements that must be satisfied (or waived) before either party is obligated to close. If a condition isn't met and isn't waived by the party for whose benefit it exists, that party can refuse to close without liability.

Bring-down of representations and warranties requires the seller's representations and warranties to be true not only as of the signing date but also as of the closing date. If a representation that was true at signing is no longer true at closing (a material customer terminated its contract, a significant lawsuit was filed, or the financial condition of the business deteriorated), the bring-down condition may not be satisfied. Most purchase agreements qualify the bring-down with a materiality standard ("true and correct in all material respects" rather than "true and correct in all respects"), which means immaterial changes between signing and closing don't give the buyer a walk-away right.

Compliance with pre-closing covenants confirms that the seller has operated the business in the ordinary course during the interim period and hasn't taken any actions that the purchase agreement prohibited (entering into material contracts without buyer consent, increasing employee compensation, making capital expenditures above a threshold, or incurring additional debt).

No material adverse effect confirms that no MAE has occurred between signing and closing. An MAE is typically defined as any event, occurrence, or change that has had, or would reasonably be expected to have, a material adverse effect on the business, operations, financial condition, or results of operations of the company, subject to negotiated carve-outs (general economic conditions, industry-wide changes, changes in law, natural disasters, and similar events that affect the broader market rather than the specific business).

Third-party consents require that specified consents have been obtained from counterparties whose contracts contain change-of-control or anti-assignment provisions. In asset purchases, key customer contracts, real property leases, equipment leases, and IP licenses that require consent to assign are typically listed as closing conditions. Failure to obtain a required consent can delay closing or, if the consent is material enough, give the buyer the right to terminate.

Seller's Closing Deliverables

At closing, the seller delivers a defined set of documents to the buyer. In an asset purchase, seller deliverables typically include a bill of sale transferring ownership of the purchased assets, an assignment and assumption agreement assigning the seller's rights under assumed contracts and the buyer's assumption of the specified liabilities, assignments of intellectual property (trademark assignments, patent assignments, copyright assignments, domain name transfer authorizations), deeds for any real property being transferred, vehicle titles for any vehicles being transferred, an officer's certificate confirming that the seller's representations and warranties are true as of the closing date and that all pre-closing covenants have been complied with, a secretary's certificate attaching the resolutions authorizing the transaction, the company's organizational documents, and good standing certificates, a FIRPTA certificate (a non-foreign person affidavit under Treasury Regulation § 1.1445-2(b)(2), confirming that the seller isn't a foreign person and that FIRPTA withholding isn't required), payoff letters from the seller's lenders with wire instructions for repaying outstanding debt at closing, UCC-3 termination statements releasing security interests on the purchased assets, resignations of officers and directors (if applicable in an equity purchase), the executed escrow agreement and evidence of deposit of the escrow amount, and all ancillary agreements (transition services agreement, consulting agreement, noncompete agreement, employment agreements for key employees).

In an equity purchase, the primary transfer document is the stock certificate or membership interest assignment (endorsed to the buyer or accompanied by a stock power or assignment of membership interests), rather than a bill of sale and individual asset assignments.

Buyer's Closing Deliverables

At closing, the buyer delivers the purchase price (by wire transfer to the seller's account, with the escrow amount wired separately to the escrow agent), the executed assumption agreement (in an asset purchase, confirming the buyer's assumption of the specified liabilities), an officer's certificate confirming that the buyer's representations are true and all buyer conditions have been satisfied, evidence of any required financing (if the purchase agreement conditions closing on the buyer's financing being in place), and all ancillary agreements requiring the buyer's signature (escrow agreement, transition services agreement, employment agreements).

Wire Transfer Mechanics

Purchase price payment occurs by wire transfer on the closing date. In most transactions, the buyer wires funds to multiple recipients simultaneously. A portion goes to the seller's account (the net purchase price after deductions). A portion goes to the escrow agent (the indemnification escrow and any working capital escrow). Portions go to the seller's lenders (payoff amounts specified in payoff letters, wired directly to the lenders to release their liens). Portions may go to the seller's advisors (investment banker fees, legal fees, and other transaction expenses being paid from closing proceeds rather than billed separately). And if the purchase price includes a seller note, the note is executed and delivered at closing rather than funded by wire.

Before initiating wires, both parties should confirm wire instructions in writing and verify them by phone to a known number (not a number provided in an email). Wire fraud targeting M&A closings, where a bad actor intercepts closing communications and substitutes fraudulent wire instructions, is a persistent and growing risk. A single misdirected wire can't be recalled once it's processed.

Post-Closing Obligations

Several significant workstreams continue after the transaction is complete.

Purchase price adjustments follow the working capital true-up process described in the purchase agreement. Within 60 to 90 days after closing, the buyer prepares a closing statement calculating actual working capital, net debt, and cash as of the closing date. If actual numbers differ from the estimates used at closing, a true-up payment is made.

State and entity filings include amendments to the company's certificate of formation (to reflect a new name, new registered agent, or new managers/officers), withdrawals of foreign qualifications in states where the entity no longer does business, and new foreign qualifications in states where the buyer plans to expand operations. In an equity purchase, no entity filings may be required because the entity continues to exist unchanged. In an asset purchase, the buyer may need to form a new entity, register it in applicable states, and obtain its own employer identification number.

Customer and vendor notifications inform the business's customers, suppliers, and other counterparties that ownership has changed and provide new contact information, billing instructions, and (where applicable) new W-9 forms. Notifications should be coordinated with the seller to maintain relationships during the transition.

IP assignments and domain transfers that weren't completed at closing (because the relevant registry or registrar requires post-closing filings) should be completed promptly. Trademark assignments are recorded with the USPTO. Patent assignments are recorded with the USPTO. Domain name transfers are processed through the registrar. Copyright assignments can be recorded with the U.S. Copyright Office.

Contract consent chasing continues for any contracts where consent to assign wasn't obtained before closing. If the purchase agreement allows closing without certain consents, the seller typically has a post-closing obligation to continue using commercially reasonable efforts to obtain them. In the interim, the seller may be required to act as the buyer's agent under the contract, providing the buyer the economic benefit of the contract until the assignment is completed.

Employee transitions in an asset purchase require the seller to terminate its employees and the buyer to hire them (typically on the closing date, so there's no lapse in employment). The buyer must establish its own payroll, benefits, and employment tax accounts. In an equity purchase, employees remain employed by the same entity and no termination or rehire is required, though the buyer may need to update benefit plans, payroll processors, and bank accounts.

Practical Recommendations

Prepare a closing checklist at least two weeks before the anticipated closing date. List every deliverable, every wire, every filing, and every condition, and assign responsibility for each item to a specific person on the deal team. Track completion daily as closing approaches.

Verify wire instructions independently. Don't rely on wire instructions provided by email without calling a known phone number to confirm. Wire fraud has affected M&A transactions at every deal size, and a misdirected wire can't be reversed.

Don't treat closing as the finish line. Post-closing obligations, including the working capital true-up, escrow administration, consent chasing, employee transitions, and IP recordings, require attention and follow-through in the weeks and months after closing. Assign responsibility for each post-closing workstream to a specific person and track deadlines.

In a deferred closing, monitor the business between signing and closing. If a material event occurs during the interim period (a key customer leaves, a lawsuit is filed, the financial condition deteriorates), evaluate whether the bring-down condition or the MAE condition has been triggered before proceeding to close.

Coordinate the closing date with the seller's lenders, the escrow agent, the buyer's lender (if the acquisition is financed), and all parties who need to provide payoff letters, release liens, or deliver consents. A closing that falls apart because one lender's payoff letter wasn't ready or one consent wasn't delivered can delay the transaction by days or weeks, which creates costs and uncertainty for both sides.
