Closing Mechanics and Post-Close Issues

The closing is not the end of the transaction. It is the beginning of a post-closing period during which the most predictable and most expensive disputes in private M&A erupt. Working capital adjustments and earnout calculations are among the most litigated areas in business acquisitions, generating millions in legal fees and, in some cases, unwinding deals that took months to negotiate. This module teaches you to anticipate and prevent these disputes before the closing documents are signed. You will learn the precise mechanics of the working capital adjustment, from peg definition through post-closing true-up, and the specific drafting techniques that prevent disputes. You will learn why earnouts fail and how to structure them so they achieve their intended purpose—bridging valuation gaps—without becoming litigation traps. And you will learn to manage the post-closing transition, holdback releases, and non-compete enforcement so that both parties walk away satisfied and the broker earns referrals, not complaints.

PART 1: THE CLOSING — WHAT ACTUALLY HAPPENS

Closing day is the culmination of months of work, but it is not a single moment. It is a coordinated sequence of events that must be carefully orchestrated. Understanding this sequence enables the broker to anticipate issues and keep the process moving.

The Closing Timeline

In the days leading up to closing, the parties finalize the definitive purchase agreement and all ancillary documents. The closing statement—a detailed schedule showing the flow of funds—is prepared and circulated. The working capital peg is confirmed, and an estimate of actual working capital as of the closing date is prepared. Any outstanding due diligence items are resolved. Third-party consents—landlord, franchisor, regulatory—are obtained and documented. Financing is finalized, and the lender provides a clear-to-close.

On closing day, the parties execute the purchase agreement and all ancillary documents. These typically include a bill of sale transferring tangible assets, an assignment and assumption agreement transferring contracts and liabilities, an intellectual property assignment, a non-compete agreement, an escrow agreement, and any employment or consulting agreements with the seller. Funds are wired according to the closing statement. The seller receives the cash portion of the purchase price, less any holdback deposited into escrow and less any transaction expenses paid at closing.

After closing, the parties have a specified period—typically 60 to 90 days—to complete the final working capital calculation. Once that calculation is finalized and any disputes resolved, the holdback is released according to its terms. Earnout periods commence and run for their specified duration.

The Broker's Role at Closing

The broker is not a lawyer and should not provide legal advice or draft legal documents. The broker's role at closing is to facilitate communication, manage the logistics, and serve as a calming presence. The broker confirms that all parties have the final documents, coordinates the execution of documents, confirms that all wires are scheduled and account information is correct, and is available throughout the day to address any last-minute issues.

The broker should also manage expectations. Closing day is stressful. Documents are voluminous. Last-minute issues inevitably arise—a missing signature, a wire that is delayed, a question about a document that requires clarification. The broker who remains calm and solution-oriented protects the deal and earns the trust of both parties.

PART 2: THE WORKING CAPITAL ADJUSTMENT — ANATOMY AND PREVENTION

The working capital adjustment is the single most litigated provision in private M&A. It generates more post-closing disputes than any other issue. Understanding the mechanics and drafting with precision prevents these disputes.

The Basic Mechanics

At the LOI stage, the parties agree on a target working capital amount—the peg. The peg represents the normal level of working capital required to operate the business. The purchase price stated in the LOI and definitive agreement assumes that the business will be delivered at closing with working capital equal to the peg.

At closing, the parties prepare an estimated closing date balance sheet and calculate estimated working capital. If the estimate shows working capital below the peg, the purchase price is reduced by the shortfall at closing, or an amount equal to the shortfall is held back pending the final calculation. If the estimate shows working capital above the peg, the purchase price is increased by the excess.

Within 60 to 90 days after closing, the buyer prepares a final closing date balance sheet and calculates final working capital. The seller has the right to review and object. If the parties agree on the final calculation, any adjustment is made—the seller pays the buyer for any shortfall, or the buyer pays the seller for any excess. If the parties cannot agree, the dispute resolution mechanism is invoked.

Why Disputes Arise

Disputes arise for several predictable reasons. The peg was not defined with precision. The LOI said "normal working capital" without specifying how it is calculated. The parties disagree on what constitutes a current asset or current liability. The parties disagree on the accounting methodology—GAAP, cash basis, or the seller's historical method. The peg was based on a single date snapshot rather than a trailing average, and that date was anomalous. The buyer's calculation of final working capital differs materially from the seller's estimate, often because the buyer writes down receivables or inventory more aggressively than the seller anticipated. The agreement does not specify a dispute resolution mechanism, leaving the parties to litigate.

Prevention Through Precise Drafting

Every element of the working capital adjustment must be defined in the definitive agreement, and ideally in the LOI as well. The peg must be defined as a specific dollar amount, calculated based on the trailing 12-month average of month-end working capital for the period ending on a specified date. A single date snapshot is not acceptable—it can be manipulated or anomalous.

The definition of working capital must specify exactly which current assets and liabilities are included. Current assets typically include accounts receivable (net of an agreed allowance for doubtful accounts), inventory (valued at the lower of cost or net realizable value), and prepaid expenses. Current assets exclude cash and cash equivalents. Current liabilities typically include accounts payable, accrued expenses, and accrued payroll. Current liabilities exclude interest-bearing debt and transaction expenses.

The accounting standard must be specified. The agreement should state whether working capital is calculated in accordance with GAAP, on a cash basis, or using the seller's historical accounting methodology consistently applied. If the seller's historical methodology is used, an exhibit should show exactly how working capital has been calculated historically.

The calculation methodology for specific items must be specified. Accounts receivable should be included net of an allowance for doubtful accounts calculated using the seller's historical methodology. Inventory should be valued at the lower of cost or net realizable value, with any obsolete or slow-moving inventory excluded or written down according to an agreed formula. Prepaid expenses should be included to the extent they provide a future benefit.

The dispute resolution mechanism must be specified. The typical mechanism provides that the buyer will deliver a final working capital calculation within 60 to 90 days after closing. The seller has 30 days to review and object. If the seller objects, the parties have 30 days to resolve the dispute through negotiation. If they cannot agree, the dispute is submitted to an independent accounting firm—typically a mutually agreed upon regional or national firm—whose determination is binding on both parties. The agreement should specify who pays for the independent accountant, typically the party whose position is further from the final determination, or the costs are split equally.

Sample Working Capital Provision Language

The following language illustrates the level of precision required:

"Net Working Capital means, as of the Closing Date, (a) the current assets of the Company included in the categories set forth on Exhibit A, minus (b) the current liabilities of the Company included in the categories set forth on Exhibit A, in each case calculated in accordance with GAAP consistently applied. Exhibit A sets forth the calculation of Net Working Capital for each month-end during the 12-month period ended June 30, 2026. The Target Net Working Capital is $450,000, which represents the average of such month-end calculations.

Within 90 days after the Closing Date, Buyer shall prepare and deliver to Seller a statement setting forth Buyer's calculation of Net Working Capital as of the Closing Date. Seller shall have 30 days to review such statement. If Seller objects, Seller shall deliver a written notice of objection specifying in reasonable detail the basis for the objection. The parties shall negotiate in good faith to resolve any objections for 30 days. If the parties cannot resolve all objections, either party may submit the unresolved objections to an independent accounting firm mutually acceptable to the parties. The independent accounting firm shall act as an expert, not an arbitrator, and its determination shall be final and binding. The fees and expenses of the independent accounting firm shall be allocated between the parties based on the relative success of their positions."

PART 3: EARNOUT DISPUTES — THE MOST PREDICTABLE RISK

Earnouts are used in approximately 25% to 30% of private M&A transactions. They are an essential tool for bridging valuation gaps—the seller believes the business will achieve certain performance levels, and the buyer is willing to pay for that performance if and when it materializes. However, earnouts produce post-close disputes in a high percentage of cases, and the disputes are predictable and preventable.

Why Earnouts Fail

Earnouts fail for three primary reasons. First, the earnout metric is easily manipulated. Revenue is the most common earnout metric, and it is also the most manipulable. The buyer can accelerate or delay revenue recognition, change pricing, or alter sales commission structures to affect revenue. EBITDA is less manipulable but still subject to expense allocation decisions.

Second, the buyer changes the business's operations post-close in ways that affect the earnout metric. The buyer reduces marketing spend, which increases short-term EBITDA but reduces long-term revenue. The buyer changes pricing strategy, which affects both revenue and EBITDA. The buyer loses key employees, which affects performance. The buyer integrates the target into its existing operations, making it difficult to track the target's standalone performance.

Third, the calculation methodology is not precisely defined. The parties agreed that the seller would receive an earnout based on "EBITDA," but they did not define how EBITDA would be calculated. They did not specify which expenses would be included or excluded. They did not specify how intercompany allocations would be handled. They did not specify the accounting standard. When the buyer calculates EBITDA at $850,000 and the seller calculates it at $1,050,000, the $200,000 gap is a lawsuit waiting to happen.

Prevention Through Earnout Design

Use EBITDA rather than revenue as the earnout metric wherever possible. EBITDA is less subject to manipulation than revenue and better reflects the true operating performance of the business. If revenue must be used—for example, in a pre-revenue or early-stage business—define revenue precisely and include protections against manipulation.

Include an explicit covenant that the buyer will operate the business in the ordinary course during the earnout period. The buyer must agree not to take any actions specifically designed to reduce or delay earnout payments. The buyer must agree to maintain the business as a distinct operating unit, not to integrate it in ways that make standalone performance tracking impossible. The buyer must agree to maintain marketing spend, capital expenditures, and headcount at levels consistent with historical practice.

Use the seller's historical accounting methodology for the earnout calculation. The buyer's accounting system may allocate expenses differently than the seller's. By requiring that the earnout be calculated using the seller's historical methodology consistently applied, the seller is protected from changes in accounting treatment that would depress the earnout.

Include audit rights. The seller must have the right to review the buyer's calculation of the earnout and to access the underlying books and records. Without audit rights, the seller must accept the buyer's calculation at face value.

Specify a dispute resolution mechanism with a short timeline. The typical mechanism provides that the buyer will deliver an earnout calculation within 45 to 60 days after the end of the earnout period. The seller has 30 days to object. If the seller objects, the parties have 30 days to resolve the dispute. If they cannot agree, the dispute is submitted to binding arbitration or to an independent accountant. The short timeline prevents the dispute from dragging on indefinitely.

Sample Earnout Provision Language

The following language illustrates the level of precision required:

"Earnout Period means the 12-month period beginning on the first day of the first full calendar month following the Closing Date. Earnout EBITDA means, for the Earnout Period, the net income of the Business before interest, taxes, depreciation, and amortization, calculated in accordance with GAAP consistently applied, subject to the adjustments set forth on Exhibit B. Exhibit B sets forth the Seller's historical calculation methodology for EBITDA.

If Earnout EBITDA for the Earnout Period equals or exceeds $850,000, Buyer shall pay Seller an earnout payment of $300,000. If Earnout EBITDA is less than $850,000, no earnout payment shall be due.

During the Earnout Period, Buyer shall operate the Business in the ordinary course consistent with past practice and shall not take any action the primary purpose of which is to reduce or delay the earnout payment. Buyer shall maintain the Business as a distinct operating unit and shall not integrate the Business in a manner that prevents the calculation of Earnout EBITDA on a standalone basis.

Within 60 days after the end of the Earnout Period, Buyer shall deliver to Seller a statement setting forth Buyer's calculation of Earnout EBITDA. Seller shall have the right, upon reasonable notice, to review Buyer's books and records relating to the calculation. Seller shall have 30 days to object to the calculation. If Seller objects, the parties shall negotiate in good faith for 30 days. If the parties cannot resolve the dispute, either party may submit the dispute to binding arbitration in accordance with the rules of the American Arbitration Association. The arbitrator shall be an independent accountant with experience in the industry."

The Acceleration Clause

An earnout should include an acceleration clause. If the buyer sells the business during the earnout period, the full remaining earnout becomes immediately payable. Without an acceleration clause, the buyer could sell the business to a third party, the earnout obligation might not be assumed, and the seller would lose the earnout entirely. The acceleration clause protects the seller from this outcome.

PART 4: OTHER POST-CLOSING ISSUES

The Holdback Release

A holdback or escrow is a portion of the purchase price—typically 10% to 15%—held back at closing to secure the seller's indemnification obligations. The holdback period is typically 12 to 18 months. At the end of the holdback period, any funds not subject to pending claims are released to the seller.

Disputes arise when the buyer makes claims against the holdback that the seller believes are unfounded. Prevention requires a clear definition of the types of claims that may be satisfied from the holdback—typically, breaches of the seller's representations and warranties—and a clear process for resolving disputed claims. The holdback agreement should specify that undisputed funds are released promptly, even if disputed claims remain outstanding.

The Transition Period

Most purchase agreements provide for a transition period during which the seller assists the buyer with knowledge transfer, customer introductions, and operational continuity. The transition period is typically 30 to 90 days, though it can be longer.

The transition period is critical to the buyer's success, but it is also a source of friction. The seller, who is accustomed to being in charge, may struggle to adapt to an advisory role. The buyer, who is eager to implement changes, may chafe at the seller's continued involvement. The broker can facilitate a smooth transition by setting clear expectations in advance, defining the seller's role and time commitment precisely, and encouraging open communication.

Non-Compete Enforcement

The seller typically agrees to a non-compete covenant as part of the transaction. The covenant prohibits the seller from competing with the business for a specified period—typically 3 to 5 years—within a defined geographic area.

Non-compete disputes arise when the seller violates the covenant, either intentionally or inadvertently. The buyer may seek injunctive relief to stop the competing activity and may seek damages. Prevention requires a non-compete covenant that is reasonable in scope and duration—covenants that are overly broad may be unenforceable—and clear communication about what activities are prohibited. The broker should ensure that the seller understands the non-compete obligations before signing.

PART 5: GLOBAL POST-CLOSING CONSIDERATIONS

Canada

Canadian working capital adjustment and earnout practices closely mirror U.S. practices. The same precision in drafting is required. Non-compete covenants are subject to provincial law, and reasonableness standards vary by province.

United Kingdom

In the UK, completion accounts are the standard mechanism for post-closing price adjustments, similar to the U.S. working capital adjustment. The completion accounts mechanism is often more detailed, with specific provisions for the preparation of completion accounts, the review period, and dispute resolution. Earnouts are common, and the same issues arise. The UK Takeover Code imposes additional requirements for public company transactions.

Australia

Australian practice uses completion accounts and earnouts similar to U.S. and UK practice. Vendor finance—seller notes—is common in smaller transactions, which adds another layer of post-closing complexity. The seller's ongoing financial interest in the business's performance creates both alignment and potential friction.

European Union

Post-closing practices vary across EU member states. In Germany, purchase price adjustments are common and often subject to detailed contractual provisions. In France, earnouts are less common than in the U.S. and UK, but they are used in certain transactions. Cross-border transactions require careful attention to governing law and dispute resolution mechanisms.

Asia-Pacific

In Singapore, post-closing adjustments and earnouts follow international standards. In Japan, post-closing disputes are less common, in part because transactions are often structured to avoid contingent payments and because the business culture emphasizes relationship preservation over litigation. In China, post-closing disputes are complicated by the legal system and enforcement challenges.

KEY TAKEAWAYS

The working capital adjustment is the single most litigated provision in private M&A. Prevent disputes by defining the peg precisely, using a trailing 12-month average, specifying exactly which assets and liabilities are included, and agreeing on the accounting standard and dispute resolution mechanism.

Earnouts are used in 25% to 30% of transactions and produce disputes in a high percentage of cases. Use EBITDA rather than revenue as the metric, include a covenant to operate in the ordinary course, use the seller's historical accounting methodology, and include audit rights and a dispute resolution mechanism.

The holdback release process should be clearly defined. Undisputed funds should be released promptly, even if disputed claims remain outstanding.

The transition period is critical to buyer success but can be a source of friction. Set clear expectations in advance and define the seller's role precisely.

Non-compete covenants must be reasonable in scope and duration to be enforceable. Ensure the seller understands the obligations before signing.

The broker's role at closing is to facilitate communication, manage logistics, and serve as a calming presence. The broker does not provide legal advice or draft documents.

Post-closing practices vary globally, but the principles of precise drafting, clear definitions, and agreed dispute resolution mechanisms are universal.
