Whether you are buying a competitor, acquiring a complementary business, or preparing to sell the company you have spent years building, a merger or acquisition is one of the most consequential transactions a business owner will ever undertake. The stakes are high, the documentation is dense, and the legal and financial implications extend well beyond closing day. Understanding how these deals work and where the risks are concentrated will help you move through the process with confidence.
Asset Purchase vs. Stock Purchase: The Foundational Choice
The most significant structural decision in any acquisition is whether to buy the assets of a business or the equity ownership of the entity itself. The difference is not merely technical; it determines what you own, what liabilities you assume, and how the deal is taxed.
In an asset purchase, the buyer selects specific assets to acquire from the selling entity. This typically includes equipment, inventory, intellectual property, customer contracts, and goodwill. Critically, in an asset purchase, the buyer generally does not assume the seller's undisclosed or contingent liabilities. If the seller has an unresolved employment claim, a pending tax audit, or an environmental issue the buyer did not know about, that liability stays with the seller's entity rather than transferring to the buyer. For this reason, buyers tend to prefer asset purchases whenever possible.
In a stock purchase (or membership interest purchase for LLCs), the buyer acquires the ownership interests of the entity itself. The entity and all of its history come along with the deal, including every liability, contract, obligation, and potential claim that has ever attached to it. Stock purchases are simpler in some respects because contracts and licenses transfer automatically without third-party consents, but the liability exposure is broader. Sellers frequently prefer stock sales for tax reasons, since gains on equity sales may qualify for capital gains treatment rather than ordinary income rates that often apply to asset sales.
The negotiation between buyers who want asset deals and sellers who want stock deals is a common feature of middle-market transactions. How this tension resolves depends on the nature of the business, the tax positions of the parties, and the quality of the seller's representations and indemnities. Our M&A practice regularly structures creative solutions that satisfy both parties' core objectives while allocating risk fairly.
The Letter of Intent: More Important Than Many Buyers Realize
Most acquisitions begin with a letter of intent (LOI), sometimes called a term sheet. The LOI is typically described as non-binding, which creates a false sense of security for parties who do not read it carefully. While the economics of a deal are usually stated as non-binding pending final documentation, certain provisions in an LOI are almost always binding: exclusivity, confidentiality, and expense allocation.
Exclusivity is particularly significant for sellers. Once you sign an LOI granting a buyer exclusivity, you are typically barred from soliciting or entertaining competing offers for 30 to 90 days. If the deal falls through during due diligence, you have lost months of marketing time. Negotiate exclusivity periods carefully, tie them to the buyer's demonstrated diligence progress, and include provisions that terminate exclusivity if the buyer materially changes the deal terms.
The LOI also establishes the framework for the purchase price, deal structure, and key conditions that will govern the definitive agreement. Terms that are poorly defined in the LOI often become contentious later. Ambiguities about working capital adjustments, treatment of earnouts, or scope of representations tend to cost far more to resolve in the definitive agreement than they would have if addressed clearly at the LOI stage.
Having experienced contract counsel review and negotiate your LOI before you sign is not an optional step. It is where you set the terms of the entire deal.
Due Diligence: What Buyers Must Investigate
Due diligence is the buyer's opportunity to verify everything the seller has represented and to identify risks that were not disclosed. A thorough due diligence process typically spans legal, financial, operational, and tax dimensions. Gaps in due diligence do not reduce a buyer's liability for the liabilities they assume; they simply mean the buyer was surprised.
Legal due diligence covers the target company's organizational documents, capitalization, material contracts, pending or threatened litigation, intellectual property ownership, employment agreements, regulatory compliance, and real estate obligations. Every material contract should be reviewed for change-of-control provisions, which may give counterparties the right to terminate the agreement upon an acquisition. In businesses that depend on a handful of key customer contracts or technology licenses, a change-of-control clause in a single agreement can fundamentally alter the value of the deal.
Financial due diligence examines the accuracy of the financial statements, the quality of earnings, customer concentration risk, recurring versus one-time revenue, accounts receivable aging, and the true cash generation of the business. Many sellers present EBITDA figures that have been adjusted for owner compensation, discretionary expenses, and one-time items. Understanding what is a legitimate adjustment and what is wishful thinking requires both financial expertise and skepticism.
Employment and HR due diligence is frequently underweighted by buyers and is a significant source of post-closing surprises. Review all employment agreements, independent contractor classifications, benefits plans, and any history of employment claims. Worker misclassification issues, wage and hour violations, and unfunded retirement obligations can generate substantial liability that is not visible on a balance sheet. Our employment law practice assists buyers in identifying and quantifying these risks before closing.
Intellectual property due diligence is critical in any business where brand, technology, or proprietary processes are central to value. Confirm that the seller actually owns the IP it claims to own. Software developed by independent contractors, for instance, is often not owned by the hiring company unless there is a written assignment in place. Review trademark registrations, patents, trade secrets protocols, and any outstanding IP disputes. For technology companies, this is often the most value-determinative part of the entire diligence process. See our overview of IP protection for technology businesses for context on what to look for.
Representations, Warranties, and Indemnification
The definitive purchase agreement contains extensive representations and warranties from the seller about the condition of the business. These are the seller's promises that specific facts are true as of closing. Common representations cover the accuracy of financial statements, the absence of undisclosed liabilities, the validity of material contracts, ownership of intellectual property, compliance with laws, the accuracy of employee-related disclosures, and the absence of pending litigation.
The indemnification provisions of the purchase agreement establish what happens when a representation turns out to be false. Typically, the seller agrees to indemnify the buyer for losses arising from breaches of representations, up to a specified dollar cap and subject to a minimum threshold (the basket or deductible) below which no claim can be made. Negotiating the scope, cap, basket, and survival period of indemnification obligations is one of the most heavily negotiated aspects of any deal.
Representations and warranties insurance (RWI) has become common in middle-market transactions above $20 million. RWI allows the buyer to make an insurance claim directly against an insurer for rep breaches rather than pursuing the seller, which can simplify post-closing relationships, allow sellers to distribute deal proceeds more freely at closing, and provide buyers with coverage beyond what a seller's indemnity might realistically be worth.
Earnouts: Bridging the Valuation Gap
When a buyer and seller disagree on the value of the business, particularly when a significant portion of value is tied to future performance, earnouts provide a way to close the gap. An earnout allows the seller to receive additional consideration after closing if the business achieves defined financial or operational milestones.
Earnouts are frequently contentious post-closing. The problem is that after closing, the buyer controls the business and therefore controls the inputs that determine whether the earnout milestones are met. If the buyer changes the business's accounting policies, reduces sales and marketing investment, integrates the business into a larger operation, or reallocates overhead in ways that depress the target's reported results, the seller may find that milestones that seemed achievable at signing are impossible after closing.
Negotiating protective covenants on earnout periods is essential for sellers. These may include commitments to maintain the business as a standalone unit, to fund it at minimum defined levels, to refrain from changes in accounting treatment, and to provide the seller with audit rights and regular reporting. The more precisely the earnout metric is defined and the more clearly the buyer's obligations during the earnout period are specified, the less litigation risk both parties face after closing.
Transition Planning and Post-Closing Integration
A deal is not finished at closing; it is just entering a new phase. The transition period following an acquisition is where deals succeed or fail in practice. Key employees may leave if they are not retained and properly incentivized. Customer relationships built on personal trust with the prior owner may erode without careful attention. Operational systems may not integrate as cleanly as anticipated.
Well-negotiated deals address transition proactively. Seller transition services agreements obligate the seller to provide support for a defined period after closing. Key employee retention bonuses, structured separately from the purchase price, give critical team members a financial reason to remain through the integration period. Non-solicitation and non-competition agreements with the seller protect the buyer from having their newly acquired customer relationships immediately competed away by the prior owner.
For business owners selling as part of succession planning, the transition structure matters as much as the purchase price. How you exit the business, whether you are available for a transition period, and what restrictions you accept on future activity all affect the ultimate value you realize from the sale.
Getting the Right Team in Place Early
Successful M&A transactions require a coordinated team of advisors. The legal team handles deal structure, due diligence, and documentation. A qualified accountant or financial advisor handles financial diligence and tax structuring. In many middle-market deals, a business broker or investment banker manages the sale process, identifies buyers or targets, and negotiates the economics before legal counsel is engaged on the definitive documents.
The biggest mistake business owners make in acquisitions is engaging legal counsel too late in the process. By the time the definitive agreement arrives for review, the core economics and structure are already established from the LOI, deal-specific issues have hardened into expectations on both sides, and the buyer has often conducted months of due diligence. Getting your attorney involved at or before the LOI stage costs far less than trying to recapture leverage you gave away in an unreviewed term sheet.
