Acquisition
An acquisition is the purchase of one company by another. The term covers asset sales, stock sales, and mergers — the broadest umbrella for M&A transactions.
Full Definition
An acquisition is the purchase of one company by another — the broadest umbrella term in M&A that covers asset sales, stock sales, and statutory mergers. When people say a company was "acquired," it simply means a buyer gained control of the target's business, whether by purchasing its assets, buying its equity, or absorbing it through a legal merger.
The three primary structures: In an asset sale, the buyer cherry-picks which assets and liabilities to purchase, leaving the rest with the selling entity. This is the most common structure in SMB M&A because it gives buyers liability protection and flexibility. In a stock sale, the buyer purchases the equity of the target entity, inheriting all its assets and liabilities — both disclosed and undisclosed. Stock sales are simpler from a contract-transfer standpoint but carry more risk for buyers. In a merger, two entities combine by statute; one may absorb the other (forward merger) or a new entity may be created. Mergers require shareholder votes and are more common in larger, public company deals.
Why structure matters so much: The acquisition structure drives tax treatment, liability transfer, transaction cost, and post-closing complexity more than almost any other deal decision. The same business sold as an asset sale versus a stock sale can produce meaningfully different after-tax outcomes for both parties — often hundreds of thousands or millions of dollars on a mid-market deal. Getting the structure right requires coordination between the deal attorney and both parties' tax advisors early in the process.
Control vs. influence: An acquisition implies obtaining control — typically more than 50% of equity or effective operating control. Minority investments and joint ventures are not acquisitions in the strict sense, though they're adjacent transaction types.
In SMB M&A specifically: The overwhelming majority of small business acquisitions ($1M–$10M) are structured as asset sales. This reflects the buyer's preference to avoid inheriting unknown liabilities, and the fact that most buyers are not taking on public company complexity. Above $10M, stock sales and hybrid structures become more common, particularly when the target has valuable contracts or licenses that don't transfer easily in an asset sale.
Seller vs. Buyer Perspective
Understanding which acquisition structure you're in — and pushing for the one most advantageous to you — is one of the most important decisions you'll make in a sale. Sellers generally prefer stock sales because gain from selling equity is taxed at capital gains rates, whereas asset sales often trigger ordinary income tax on certain asset classes (inventory, receivables, depreciation recapture on equipment). The difference can easily be 10–15 percentage points of tax rate on a significant portion of the proceeds.
That said, buyers almost always prefer asset deals for SMB transactions, so sellers may need to negotiate a price gross-up to compensate for the incremental tax burden of an asset sale structure.
Structure selection is one of the first and most consequential decisions in any acquisition. Asset deals give you a clean slate — you choose what to buy, get a stepped-up tax basis in the assets, and leave unknown liabilities behind. Stock deals give you contract continuity and operational simplicity, but you inherit everything — including problems the seller doesn't know about. As a buyer in SMB M&A, push for an asset deal unless there are compelling reasons (non-transferable contracts, licenses, or government authorizations) to do a stock deal. If you must do a stock deal, widen your rep and warranty coverage and sharpen your indemnification terms.
Real-World Example
A buyer acquires a $3M revenue HVAC business. The deal is structured as an asset sale: the buyer purchases equipment, vehicles, customer contracts, the trade name, and goodwill — but not the seller's outstanding payroll tax liability from a payroll processing error two years prior. The seller's LLC remains open to pay that liability. Had it been a stock purchase, the buyer would have inherited that liability with no clean separation.
Why It Matters & Common Pitfalls
- !'Acquisition' doesn't specify the structure — confirm it early. An LOI that says 'acquire the business' without specifying asset vs. stock is incomplete. The structure should be agreed in principle before exclusivity is granted, not negotiated during due diligence.
- !Non-transferable contracts can make asset deals painful. Government contracts, certain SaaS agreements, franchise agreements, and some leases may require the counterparty's consent to assign. In an asset deal, you may not automatically get these — model this risk before choosing structure.
- !Successor liability isn't always blocked by an asset deal. Certain environmental liabilities, product liability claims on goods already sold, and specific tax obligations can follow the assets regardless of deal structure. Specialized legal review matters for businesses in regulated industries.
- !Tax elections can flip the economics. A 338(h)(10) election lets a stock sale be treated as an asset sale for tax purposes — giving buyers the basis step-up while sellers maintain some structural benefits. Always model elections alongside structure options before finalizing deal terms.
