Buying a Business in California: Asset Purchase vs. Stock Purchase

The core trade-off

• Liability: an asset buyer generally avoids pre-closing liabilities, subject to successor liability doctrines; an equity buyer inherits everything the entity owes, known or not.
• Contracts: an asset deal requires assignment and often third-party consent; an equity deal keeps contracts in place unless they contain a change-of-control clause.
• Licenses and permits: many are not assignable, which can favor an equity purchase — or require a fresh application either way.
• Tax: asset buyers typically get a stepped-up basis and better depreciation; sellers usually prefer equity treatment. This gap is real money and belongs in the price discussion.
• Employees: in an asset deal employment terminates with the seller and the buyer rehires, which triggers final pay obligations and can trigger Cal-WARN notice at scale.
• Complexity: asset deals need schedules, bills of sale, assignments, and consents; equity deals need deeper diligence and stronger indemnities.

Successor liability is not eliminated by structure

California recognizes successor liability where the buyer expressly or impliedly assumes obligations, where the transaction is a de facto merger, where the buyer is a mere continuation of the seller, or where the deal is a fraudulent effort to escape debts. Product-line liability and certain environmental, tax, and employment obligations can also follow the assets.

Wage and hour exposure deserves separate attention. California has expanded successor obligations for unpaid wage judgments in several contexts, and buyers who keep the same workforce, management, and location face the strongest arguments.

Diligence items that most often reprice a deal

• Worker classification — contractors who should have been employees, and exempt employees who fail the duties test.
• Meal and rest break practice and time records, which drive PAGA and class exposure.
• Unassignable customer contracts, or contracts with change-of-control and anti-assignment clauses.
• Missing IP assignments from founders, contractors, and developers.
• Non-competes or overbroad non-solicits in employee agreements that are unlawful in California.
• Sales and use tax exposure and unfiled returns; California allows a withholding-based tax clearance process worth using.
• Bulk sale notice requirements for certain inventory-heavy businesses.
• Real property leases with landlord consent conditions and personal guaranties.
• Pending or threatened claims, demand letters, and agency charges.

Structuring the protections

Price adjustments matter less than the indemnity architecture: survival periods that outlast the relevant statutes for wage and tax claims, escrow or holdback sized to identified risks, separate longer survival for fundamental and tax representations, and specific indemnities for known issues rather than folding them into the general basket.

Representation and warranty insurance is worth pricing on larger transactions, but it does not cover known problems — those still need a holdback or a pre-closing fix.
