The first real decision in buying or selling a business is not price — it is structure. Whether the deal is papered as an asset purchase or a stock (or membership-interest) purchase changes who inherits the liabilities, how the price is taxed, and which third parties can hold up closing. Buyers and sellers usually start on opposite sides of this question, and understanding why is the key to negotiating it well.
What each structure actually transfers
In a stock purchase, the buyer acquires the owners' equity; the company itself continues uninterrupted, with all of its assets, contracts, licenses, employees, and liabilities — known and unknown. In an asset purchase, the buyer acquires a selected list of assets (and assumes a selected list of liabilities) from the company; the selling entity survives, keeps whatever was not sold, and typically winds down after distributing the proceeds. Mergers can replicate either outcome, but for the private California deals most owners face, the asset-versus-stock choice frames everything downstream.
Liability: the buyer's core concern
Stock buyers take the company warts and all: pending and unasserted claims, tax exposure, employment liabilities, everything. Asset buyers, by contrast, generally take only the liabilities they agree to assume — which is why buyers instinctively prefer asset deals for smaller and riskier targets. But "generally" is doing work in that sentence. Successor liability doctrines can follow the assets anyway: express or implied assumption, fraudulent transfer, mere continuation of the seller's business, and California's product-line rule for certain product liability claims. Specific regimes add more — unpaid wages, certain tax obligations, and environmental liabilities can attach to asset buyers by statute. An asset structure narrows liability; diligence and indemnities still have to do the rest.
Tax: the seller's core concern
Tax is where the structures diverge most sharply. In an asset sale by a C corporation, the gain is taxed twice — once at the corporate level on the sale, and again when proceeds are distributed to shareholders. A stock sale is taxed once, to the shareholders, generally at capital gains rates, which is why C-corporation sellers push hard for stock deals. Buyers pull the other way: an asset purchase gives them a stepped-up basis in the assets, generating depreciation and amortization deductions that a stock purchase does not. For S corporations and other pass-through sellers, the double-tax problem largely falls away. For eligible S-corporation stock sales, elections under Sections 338(h)(10) or 336(e) can give the buyer an inside basis step-up while the deal still looks like an equity sale; acquisitions of LLC interests may receive similar deemed-asset-sale treatment, depending on the LLC's tax classification and the transaction. The allocation of purchase price among asset classes then becomes its own negotiation, because it sets each side's tax character and must be reported on the applicable IRS forms. Model the structures after tax before agreeing to a headline number; the same price can net a seller very different amounts.
Consents, contracts, and continuity
Asset deals require moving each asset and contract to the buyer — and many contracts prohibit assignment without the counterparty's consent. Key customer agreements, leases, and licenses can each become a closing condition and a renegotiation opportunity for the counterparty. Stock deals avoid most assignment issues because the contracting entity does not change, but watch for change-of-control clauses that trigger the same consent rights. Non-transferable regulatory licenses and permits often decide the structure by themselves. Employees follow a similar pattern: in a stock deal employment simply continues, while in an asset deal the buyer rehires, which adds friction but also lets the buyer reset terms. In California, remember that new non-compete covenants are generally void; the narrow sale-of-business exception (Bus. & Prof. Code § 16601) protects covenants given by a selling owner, not covenants imposed on rank-and-file employees.
How the negotiation usually resolves
- Small or risk-heavy targets tend toward asset purchases: buyers get liability selection and a basis step-up.
- C-corporation sellers fight for stock deals, or price the double tax into the number.
- Pass-through targets often land on equity deals with deemed-asset-sale treatment — generally one level of tax, buyer step-up, minimal consent friction.
- Whatever the structure, the risk allocation lives in the representations, indemnities, escrows, and any insurance — which is where M&A counsel earns its keep.
Structure should be settled in the letter of intent, not discovered in drafting; reversing it later reprices the deal. Sellers preparing for market should also get their corporate records in order early, since diligence problems constrain structure choices too.
