A purchase agreement is the foundational document governing the sale of a business. It allocates risk between buyer and seller, defines what is being sold, establishes the purchase price and how it will be paid, and sets forth the obligations of both parties before and after closing. When this document contains gaps, ambiguities, or poorly negotiated terms, the consequences can be severe: unexpected liabilities, disputed payments, regulatory violations, and costly post-closing litigation.
For business owners on either side of a transaction, the stakes are enormous. Sellers may find themselves liable for obligations they believed they left behind. Buyers may discover that the business they acquired is worth far less than what they paid. In both cases, the root cause often traces back to mistakes in the purchase agreement itself.
Asset Purchase vs. Stock Purchase: Choosing the Wrong Structure
One of the first and most consequential decisions in any acquisition is whether to structure the deal as an asset purchase or a stock purchase. In an asset purchase, the buyer selects specific assets and liabilities to acquire. In a stock purchase, the buyer acquires the entity itself, including all of its assets, liabilities, contracts, and obligations.
Buyers generally prefer asset purchases because they can pick and choose what they want, leaving behind unwanted liabilities such as pending lawsuits, environmental cleanup obligations, or unfavorable contracts. Sellers often prefer stock purchases because they transfer the entire entity and its associated risks to the buyer.
The mistake many business owners make is failing to fully analyze the implications of the chosen structure. An asset purchase may trigger consent requirements under key contracts, meaning that customers or vendors must agree to the assignment. A stock purchase may saddle the buyer with unknown liabilities that surface months or years after closing. Tax consequences also differ significantly between the two structures, and choosing incorrectly can result in millions of dollars in unnecessary tax exposure.
Representations and Warranties: The Hidden Minefield
Representations and warranties are statements of fact made by the seller (and sometimes the buyer) about the condition of the business. They cover areas such as financial statements, compliance with laws, intellectual property ownership, material contracts, employee matters, tax filings, and environmental conditions.
These provisions serve two critical functions. First, they require the seller to disclose material information about the business. Second, they form the basis for indemnification claims if those statements turn out to be inaccurate.
Common mistakes in this area include:
- Overly broad or vague representations that create ambiguity about what is actually being warranted
- Failure to include materiality qualifiers where appropriate, exposing the seller to claims over trivial inaccuracies
- Inadequate disclosure schedules that fail to carve out known issues from the representations
- Insufficient survival periods that limit the time a buyer has to discover and assert claims for breaches
For sellers, the risk is making representations that are too broad without proper exceptions. For buyers, the risk is accepting representations that are so heavily qualified that they provide no meaningful protection.
Due Diligence Failures: What You Don’t Know Will Hurt You
Due diligence is the investigative process through which a buyer examines the target company’s financial, legal, operational, and commercial condition. It is the buyer’s opportunity to verify the seller’s claims and identify risks before committing to the transaction.
The most damaging due diligence failures typically involve:
- Incomplete financial analysis: Failing to scrutinize revenue recognition practices, off-balance-sheet liabilities, or the sustainability of recent financial performance
- Overlooking regulatory compliance: Missing pending investigations, expired permits, or noncompliance with industry regulations that could result in fines or operational shutdowns
- Ignoring employee and labor issues: Failing to identify pending employment claims, misclassification of workers, or key employee retention risks
- Inadequate intellectual property review: Not confirming ownership, validity, and enforceability of patents, trademarks, trade secrets, and copyrights that are central to the business’s value
Business owners who rush through due diligence or treat it as a formality often pay dearly. The cost of thorough due diligence is a fraction of the losses that result from discovering problems after closing.
Earnout Disputes and Working Capital Adjustments
Many purchase agreements include earnout provisions, where a portion of the purchase price is contingent on the business achieving certain financial targets after closing. Earnouts can bridge valuation gaps between buyer and seller, but they are also one of the most litigated provisions in M&A transactions.
Disputes commonly arise over:
- How post-closing financial performance is measured: Differences in accounting methods, treatment of extraordinary items, and allocation of corporate overhead can all affect whether earnout targets are met
- The buyer’s obligation to operate the business: Sellers often argue that buyers deliberately managed the business in ways that reduced earnout payments, while buyers contend they had discretion to run the business as they saw fit
- Ambiguous definitions of key financial metrics: Terms like “net revenue,” “EBITDA,” or “operating income” can be calculated in multiple ways unless the agreement specifies the methodology in detail
Working capital adjustments present similar challenges. Most purchase agreements establish a target working capital amount, with the purchase price adjusted upward or downward based on actual working capital at closing. Disputes over what constitutes working capital, how specific items should be classified, and the timing of measurements are extremely common.
The solution is precision in drafting. Earnout provisions should specify accounting principles, define every financial term, establish dispute resolution mechanisms, and clearly state the buyer’s obligations regarding operation of the business during the earnout period.
Indemnification: Baskets, Caps, and Escrow Holdbacks
Indemnification provisions determine how losses arising from breaches of the purchase agreement are allocated between buyer and seller. These provisions typically include several key components that require careful negotiation.
Baskets establish a threshold that must be met before a party can make an indemnification claim. A “deductible” basket means the indemnifying party is only responsible for losses exceeding the basket amount. A “tipping” basket means that once the threshold is exceeded, the indemnifying party is responsible for all losses from the first dollar. The choice between these two approaches, and the size of the basket, can mean millions of dollars in exposure.
Caps limit the maximum amount of indemnification liability. A cap that is too low leaves the buyer without adequate protection. A cap that is too high exposes the seller to disproportionate risk relative to the purchase price received.
Escrow holdbacks involve setting aside a portion of the purchase price in an escrow account to secure the seller’s indemnification obligations. The amount of the holdback, the duration of the escrow period, and the conditions for release all require careful negotiation. Sellers want minimal holdbacks released quickly. Buyers want substantial holdbacks retained long enough to identify and assert claims.
Non-Compete Provisions, Closing Conditions, and MAC Clauses
Several additional provisions in purchase agreements frequently generate disputes when not properly drafted.
Non-compete provisions in the M&A context restrict the seller from competing with the business after closing. These provisions must be reasonable in scope, duration, and geography to be enforceable. A non-compete that is too narrow gives the seller room to siphon away customers and employees. One that is too broad may be struck down by a court as unenforceable, leaving the buyer with no protection at all.
Closing conditions are requirements that must be satisfied before the transaction can close. These may include regulatory approvals, third-party consents, absence of litigation, accuracy of representations at closing, and completion of financing. Poorly drafted closing conditions can give one party an excuse to walk away from the deal or create uncertainty about whether the conditions have been met.
Material adverse change (MAC) clauses allow the buyer to terminate the agreement if a significant negative event affects the target business between signing and closing. The definition of what constitutes a material adverse change is one of the most heavily negotiated provisions in any purchase agreement. Sellers push for narrow definitions with broad carve-outs for industry-wide conditions, changes in law, and general economic downturns. Buyers want broad definitions that capture any meaningful deterioration in the business.
Post-Closing Obligations and Transition Planning
The purchase agreement does not end at closing. Post-closing obligations govern the relationship between buyer and seller in the months and years following the transaction. These obligations may include transition services agreements, where the seller continues to provide certain operational support; employee retention commitments; cooperation on tax filings and audits; and resolution of any pre-closing claims or disputes.
Business owners frequently underestimate the importance of post-closing provisions. A seller who is obligated to provide transition services without clear compensation terms or duration limits may find the obligation far more burdensome than anticipated. A buyer who fails to secure adequate transition support may struggle to maintain customer relationships, retain key employees, or operate critical systems.
Practical Steps for Business Owners
Whether you are buying or selling a business, the following steps can help you avoid the most costly mistakes:
- Engage experienced M&A counsel early. Purchase agreement negotiations require specialized expertise. Involving your attorney from the beginning of the process ensures that deal structure, tax planning, and risk allocation are addressed before commitments are made.
- Invest in thorough due diligence. Do not cut corners on financial, legal, regulatory, and operational review. The cost of due diligence is minimal compared to the cost of post-closing surprises.
- Negotiate indemnification provisions carefully. Understand the implications of baskets, caps, survival periods, and escrow holdbacks. These provisions determine your financial exposure if problems arise after closing.
- Define financial terms with precision. If your deal includes earnouts or working capital adjustments, specify accounting methods, define every metric, and include worked examples where possible.
- Plan for post-closing integration. Address transition services, employee retention, customer communication, and operational continuity in the purchase agreement itself.
Conclusion
Purchase agreements are among the most consequential contracts a business owner will ever sign. The difference between a successful acquisition and a costly disaster often comes down to the quality of the agreement and the diligence applied before closing. By understanding the common mistakes and taking proactive steps to address them, business owners can protect their investments, preserve their businesses, and avoid the disputes that turn promising transactions into expensive cautionary tales.
