Asset Purchase vs. Stock Purchase: Thorough Comparison

One of the most consequential decisions in any business acquisition is whether to structure the transaction as an asset purchase or a stock purchase (also called a share purchase or equity purchase). This structural choice affects taxes, liability exposure, contract transferability, and post-acquisition operations. For search fund entrepreneurs and self-funded acquirers, understanding the trade-offs is essential for negotiating the best deal structure.

What is an asset purchase?

In an asset purchase, the buyer acquires specific assets and liabilities of the business rather than the entity itself. The buyer cherry-picks which assets to acquire (equipment, inventory, customer lists, intellectual property, real estate) and which liabilities to assume. The selling entity continues to exist (at least temporarily) and retains any assets and liabilities not transferred to the buyer.

Asset purchases are the most common structure for small business acquisitions. According to SBA lending data, approximately 70-80% of SBA-financed acquisitions are structured as asset purchases.

What is a stock purchase?

In a stock purchase, the buyer acquires the ownership interests (shares, membership units, or partnership interests) of the selling entity. The business entity itself: including all assets, liabilities, contracts, and obligations, transfers to the new owner. Nothing changes about the entity except who owns it.

Stock purchases are more common in larger transactions, regulated industries (where licenses are entity-specific), and situations where contract assignment is problematic.

Key differences

Tax implications

Tax considerations are often the primary driver of the asset vs. stock decision, and the interests of buyers and sellers are typically opposed:

Buyer prefers asset purchase:In an asset purchase, the buyer gets a “stepped-up” tax basis in the acquired assets, meaning they can depreciate or amortize the full purchase price over time. This creates significant tax deductions in the years following the acquisition. For a $5M acquisition, the tax savings from a stepped-up basis can exceed $500K-$1M over the depreciation period.

Seller prefers stock purchase: In a stock purchase, the seller pays capital gains tax on the difference between their basis in the stock and the sale price, a single level of tax. In an asset purchase of a C corporation, the seller faces double taxation: the corporation pays tax on the asset sale, then the shareholders pay tax again on the liquidating distribution. For S corporations, pass-through entities, and LLCs, the impact is less severe but still favors stock sales in most cases.

Liability exposure

Asset purchase advantage: The buyer can exclude known and unknown liabilities from the transaction. Only the specifically assumed liabilities transfer. This protects against undisclosed debts, pending litigation, environmental liabilities, and tax obligations of the selling entity.

Stock purchase risk:The buyer acquires the entity “warts and all,” including all liabilities, even those that were unknown at closing. This makes thorough due diligence even more critical in stock purchases. Representations, warranties, and indemnification provisions in the purchase agreement become the primary protection.

Contract and license transferability

Asset purchase challenge: Contracts, leases, licenses, and permits often have anti-assignment clauses that require counterparty consent for transfer. In an asset purchase, every key contract must be individually assigned, which can be time-consuming and creates the risk of counterparties renegotiating terms. Government permits and industry licenses may not be transferable at all.

Stock purchase advantage: Because the entity itself does not change, contracts remain in place without assignment. Customers, suppliers, landlords, and regulators may not even need to be notified (though best practice is to inform them). This is particularly important in:

• Healthcare (Medicare/Medicaid provider numbers are entity-specific)
• Financial services (regulatory licenses are entity-specific)
• Government contracting (contract novation is complex and slow)
• Real estate-heavy businesses (lease assignment can trigger landlord consent)

Employee considerations

Asset purchase: Employees are technically terminated by the selling entity and rehired by the buyer. This resets tenure for benefits, PTO accrual, and employment agreements. It also creates an opportunity to selectively rehire, but can create anxiety and turnover during the transition.

Stock purchase: Employment continues uninterrupted. Employees retain their tenure, benefits, and agreements. This is generally better for management transition and employee retention.

When to use each structure

Use an asset purchase when:

• Buying a C corporation (to avoid double taxation on the seller’s side, negotiate a price adjustment)
• You want the tax benefit of a stepped-up asset basis
• There are known or suspected liabilities you want to exclude
• The business is straightforward with easily transferable contracts
• You are using SBA financing (SBA lenders generally prefer asset purchases)
• You want a clean start with selective asset and liability assumption

Use a stock purchase when:

• The business has non-transferable licenses, permits, or contracts (regulated industries)
• Contract assignment would be overly complex or risky
• The seller is an S corporation, LLC, or partnership (where double taxation is less of a concern)
• You want to preserve employee continuity and benefit plans
• The business has valuable tax attributes (NOLs, R&D credits) you want to inherit
• Speed is critical and you want to avoid the complexity of individual asset transfers

The 338(h)(10) election: best of both worlds

For S corporation acquisitions, the IRC Section 338(h)(10) election allows a stock purchase to be treated as an asset purchase for tax purposes. The buyer gets the stepped-up basis of an asset purchase while maintaining the contract and license continuity of a stock purchase. Both buyer and seller must agree to the election, and the seller faces tax implications as if they sold assets (not stock).

The 338(h)(10) election is increasingly common in search fund transactions because it aligns the interests of buyer and seller better than a pure asset or stock deal. Your tax advisor can model the specific impact for your deal.

Purchase price allocation

In an asset purchase, the purchase price must be allocated across the acquired assets for tax purposes using the “residual method” (IRC Section 1060). The allocation determines the depreciation and amortization schedule and has significant tax implications for both parties:

• Tangible assets: Allocated at fair market value and depreciated over their useful lives (5-39 years depending on asset class)
• Intangible assets: Customer lists, non-competes, and other identified intangibles are amortized over 15 years
• Goodwill: The residual amount (purchase price minus fair market value of all identified assets) is also amortized over 15 years

Buyers generally want to allocate more to short-lived assets and non-competes (faster depreciation/amortization), while sellers prefer allocation to goodwill and capital assets (capital gains rates). This is a key negotiation point that should be addressed in the LOI or purchase agreement.

European considerations

The asset vs. stock distinction exists in European jurisdictions but with different tax and legal frameworks:

• France: Share purchases (cession de parts/actions) are more common due to transfer tax advantages. Asset purchases (cession de fonds de commerce) trigger registration duties of 3-5%. See ETA in France.
• Germany: Share deals (Anteilskauf) vs. asset deals (Unternehmenskauf) have different trade tax and VAT implications. See ETA in Germany.
• UK: Share purchases avoid stamp duty land tax on embedded real estate but inherit all liabilities. Asset purchases allow capital allowances. See ETA in the UK.

Practical tips for search fund acquirers

• Start with an asset purchase as your default structure and only switch to stock if there is a compelling reason
• Model the tax impact of both structures early in due diligence the difference can be hundreds of thousands of dollars
• If the seller insists on a stock deal, negotiate a price adjustment to reflect the buyer’s lost tax benefit
• For S corps, always evaluate the 338(h)(10) election as a potential compromise
• Address the structure early in LOI negotiations changing structure after signing creates friction
• Engage tax counsel and your CPA before finalizing the structure

Frequently asked questions

Which structure do SBA lenders prefer for acquisitions?

SBA lenders overwhelmingly prefer asset purchases. According to SBA lending data, approximately 70-80% of SBA-financed acquisitions are structured as asset deals. The primary reasons are cleaner collateral documentation (the lender takes a first lien on specifically identified assets), avoidance of successor liability risk, and simpler loan administration. If your deal requires a stock purchase (for example, due to non-transferable licenses or contracts), you will need to find an SBA lender with experience in stock deals and should expect additional documentation requirements, including more extensive representations and warranties and potentially higher equity injection requirements.

How does the 338(h)(10) election affect both buyer and seller?

The IRC Section 338(h)(10) election allows a stock purchase to be treated as an asset purchase for tax purposes, but it requires mutual consent. For buyers, the benefit is significant: a stepped-up tax basis in the acquired assets that generates depreciation and amortization deductions worth $500K-$1M+ over the recovery period on a typical $5M-$15M acquisition. For S corporation sellers, the election triggers tax as if assets were sold (ordinary income on recaptured depreciation, capital gains on the remainder), which can increase their tax bill by 5-15% compared to a straight stock sale. According to the American Bar Association’s M&A Committee, the 338(h)(10) election has become the default structure for S corporation search fund acquisitions, with the buyer typically compensating the seller through a purchase price adjustment of 3-8% to offset the seller’s additional tax burden.

What happens to employee benefits in each structure?

In an asset purchase, employees are technically terminated by the seller and rehired by the buyer. This resets benefits enrollment periods, PTO accrual, and tenure-based benefits. According to the Society for Human Resource Management (SHRM), this disruption is the single largest source of employee anxiety during acquisitions. The buyer must establish new benefit plans or adopt the seller’s plans, and there is typically a gap in coverage that must be managed carefully to retain key talent. In a stock purchase, employment continues uninterrupted, employees keep their tenure, benefit elections, and accrued PTO.
