The Most Important Business Decision: Share Purchase or Asset Purchase?
When you’re buying a business, one of the first questions is: are you buying the company’s shares (meaning you own the legal entity) or its assets (the business, equipment, IP, contracts – but not the entity itself)?
This isn’t just a technical legal distinction. It fundamentally changes your risk profile, your tax position, your costs, and what happens after closing. Get this wrong and you could inherit millions in hidden liabilities or lose critical customer contracts in the transition.
Share Purchase Agreement: What It Is
In a share purchase agreement, you buy all the shares of the seller’s corporation. You become the owner of the legal entity and everything inside it – assets, liabilities, contracts, employees, history, and all.
What transfers automatically:
- All contracts (customer agreements, vendor relationships, partnerships)
- All employees and their obligations
- All intellectual property and trademarks
- All licenses and permits (usually)
- All liabilities, known and unknown
- All historical baggage (lawsuits, regulatory issues, warranties issued to customers)
Example: You buy ABC Widget Company. ABC has 50 customers, 5 employees, a lease on a manufacturing facility, and some old litigation from 2019 that the seller didn’t mention. When you buy the shares, all of it is now yours – good and bad.
Asset Purchase Agreement: What It Is
In an asset purchase agreement, you buy the business’s assets – equipment, inventory, customer contracts (assigned individually), goodwill, IP, brand – but you don’t buy the legal entity itself. The seller’s corporation might continue to exist (empty) or be dissolved.
What transfers: Only what you explicitly agree to purchase.
What doesn’t transfer: Liabilities, unless you assume them in writing.
Example: You buy ABC Widget Company’s assets. You get the equipment, the IP, the customer contracts (that you assign), the lease (if the landlord consents). But you don’t take ABC the company itself – you don’t inherit the old litigation, the environmental liability, the unpaid taxes, or the severance obligations to ex-employees.
Share Purchase vs. Asset Purchase: Head-to-Head Comparison
1. LIABILITY EXPOSURE
Share purchase: You inherit ALL liabilities – known and unknown. Even if you didn’t know about it, you own the company that’s liable.
Asset purchase: You only inherit liabilities you explicitly assume. Unknown liabilities stay with the seller.
Winner for buyer: Asset purchase (much lower risk)
2. CONTRACT AND RELATIONSHIP CONTINUITY
Share purchase: All contracts transfer automatically. Customer relationships stay intact. Employees stay employed by the same company.
Asset purchase: You have to assign each contract individually. Many require third-party consent. If you can’t get consent, you lose the contract.
Winner for buyer: Share purchase (if you can get all contracts)
3. TAX TREATMENT FOR THE BUYER
Share purchase: You buy shares at cost basis. When you depreciate the company’s assets, you use their original cost basis (usually much lower than fair market value). Over time, this reduces your depreciation deductions.
Asset purchase: You allocate the purchase price to each asset. Your cost basis is the purchase price. This higher depreciable base means larger depreciation deductions and tax shields over time.
Winner for buyer: Asset purchase (better tax position)
4. HST AND SALES TAX
Share purchase: No HST. Share transfers aren’t subject to sales tax in Canada.
Asset purchase: HST applies in Ontario (13% typically). If you’re buying $1M in assets, you owe $130K in HST.
Impact: This can swing a deal. Asset purchases look more expensive because of HST.
Winner for buyer on cost: Share purchase (no HST)
5. DUE DILIGENCE REQUIRED
Share purchase: You need extensive due diligence because you inherit unknown liabilities. Deep dive into contracts, litigation, compliance, environmental issues, employment obligations.
Asset purchase: Due diligence is still necessary, but narrower. You only care about the assets you’re buying and the liabilities you’re assuming.
Winner for simplicity: Asset purchase (less risky, less exhaustive due diligence needed)
6. THIRD-PARTY CONSENTS
Share purchase: Generally, share transfers don’t require third-party consent (the company stays the same entity; it just has new ownership). Some contracts have change-of-control provisions, but these are less common than “assignment requires consent” language.
Asset purchase: Most customer and vendor contracts require consent to be assigned. If you’re acquiring business, you might lose critical contracts if the customer says no.
Winner for ease of closing: Share purchase (fewer consents needed)
7. INDEMNIFICATION
Share purchase: Seller makes representations and warranties about the accuracy of information. If something is false, you sue for breach of warranty and indemnification.
Asset purchase: Same representations and warranties, but seller still owns the shell company if something goes wrong. Less tangible to enforce against (seller could wind down the empty company).
Winner for enforcement: Share purchase (seller still owns operating assets if there’s a claim)
8. EMPLOYEE CONTINUITY
Share purchase: Employees stay employed by the same company. No change in employer, benefits, or pension continuity (important in larger deals).
Asset purchase: You hire the employees as a new employer. This can be a fresh start (clean slate on benefits, terms) or a liability (severance if you don’t retain someone).
Winner for simplicity: Share purchase
9. CUSTOMER AND VENDOR RELATIONSHIPS
Share purchase: All contracts and relationships transfer. Customers and vendors deal with the same company entity they’ve been dealing with.
Asset purchase: Contracts transfer only with consent, and the customer is now dealing with a new entity. This can create relationship friction and retention risk.
Winner for relationship continuity: Share purchase
The Decision Matrix: When to Choose Each Structure
Choose SHARE PURCHASE when:
- The business has many customer/vendor contracts that are hard to reassign
- Customer relationships and brand continuity are critical to valuation
- The business holds licenses or permits that can’t easily be transferred
- You want to retain all employees and maintain pension/benefit continuity
- The seller can provide strong warranties (and indemnification) around hidden liabilities
- The target company has clean due diligence – no major litigation, environmental issues, or regulatory risk
Choose ASSET PURCHASE when:
- You want to avoid unknown liabilities (this is the primary reason)
- You can live without some contracts and relationships (you’ll lose the ones where consent is withheld)
- The business has HST considerations that make asset structure unfavorable (you’d pay HST, so asset purchase doesn’t add much more cost)
- There’s significant historical litigation, environmental risk, or regulatory baggage
- You’re restructuring ownership (combining businesses, changing corporate structure)
- You want a fresh start with employment terms and benefits
The Practical Reality: Seller Preference Often Drives the Deal
In theory, buyers prefer asset purchases (lower risk) and sellers prefer share purchases (simpler, cleaner sale). In practice, the deal size and market dynamics often determine structure:
Smaller acquisitions ($500K-$5M): Asset purchases are most common. Buyers want to avoid inherited liability. Sellers accept asset structure if the price is right.
Mid-market ($5M-$50M): Share purchases become more common, but only if seller can provide strong reps and warranties. Buyers demand indemnification baskets and caps.
Large acquisitions ($50M+): Share purchases are standard. At this scale, indemnification insurance and escrows are available to manage risk.
Hybrid Approach: Share Purchase with Asset Carve-Outs
Sometimes you negotiate a middle ground: share purchase, but you carve out problematic assets or liabilities.
Example: You buy ABC Company as a share purchase, but:
- The seller retains the old real estate (you lease it from them)
- The seller keeps liability for pre-acquisition lawsuits
- The seller keeps the pension obligation for retired employees
This gives you the continuity benefits of a share purchase (all contracts stay, employee relationships intact) while shedding specific known risks. It’s more complex to structure (requires multiple agreements and careful indemnification), but it can be the sweet spot.
Tax Implications: Talk to Your Accountant
For the Buyer:
- Share purchase: Lower depreciation base means lower tax deductions over time
- Asset purchase: Higher depreciation base means larger tax shields
Talk to your tax adviser about which is more favorable. Sometimes the tax benefit of asset purchase outweighs the HST cost.
For the Seller:
- Share purchase: Usually taxed as capital gain (50% inclusion rate in Canada = favorable)
- Asset purchase: Gains on individual assets might be ordinary income (recapture on equipment, for example), which is less tax-efficient
This is why sellers often prefer share purchases – better tax treatment. This can be a negotiation point.
Common Issues in Share Purchases
Unknown Liabilities
You discover the seller didn’t disclose: unpaid wages, a customer lawsuit, environmental contamination. With share purchase, these are now your problem. Mitigation: strong representations, robust due diligence, indemnification with adequate basket and tail period.
Representations Not Holding Up
The seller warranted that a key customer contract was rock-solid, but the customer exercises a termination right post-closing. You can claim indemnification, but enforcing it is slow and expensive. Mitigation: escrow some of the purchase price to cover claims.
Undisclosed Liabilities to Former Employees
You inherit obligations for vacation pay, severance, or pension liability. Ontario employment law can make these substantial. Mitigation: Seller retains employment liabilities pre-closing, or represents that all such obligations have been satisfied.
Common Issues in Asset Purchases
Lost Customer Contracts
Key customer won’t consent to contract assignment. You lose the relationship. This is the biggest risk with asset purchases. Mitigation: Get consents in writing BEFORE closing, not after.
Seller Winds Down Empty Company
After closing an asset deal, the seller’s company is empty. If you later discover a liability or breach of warranty, the seller’s company might be dissolved or judgment-proof. Mitigation: Escrow funds or obtain indemnification insurance.
Successor Liability
Even in an asset purchase, you might inherit certain liabilities by law (employment obligations, environmental liability in some cases, tax obligations). Ontario law can impose successor employer obligations in certain circumstances. Mitigation: Carefully define assumed vs. excluded liabilities in the agreement.
FAQ: Share vs. Asset Purchase
Q: Can the structure of the deal affect whether I can get financing?
A: Yes. Lenders often prefer share purchases because contracts and customer relationships transfer automatically. Asset purchases can be harder to finance if critical contracts are in jeopardy.
Q: What if the seller won’t agree to my preferred structure?
A: Negotiate price. If the seller insists on asset purchase (which is riskier for the buyer), the price should be lower to reflect that risk. If you insist on asset purchase and the seller objects, offer a premium.
Q: How important is indemnification insurance?
A: Very important in share purchases over $5M. It’s a one-time premium (1-5% of purchase price) and covers unknown liability breaches. Highly recommended.
Q: In an asset purchase, do I inherit environmental liability?
A: Generally no, unless you assume it or Ontario law imposes successor liability. But do a Phase 1 environmental assessment before closing an asset deal involving property or manufacturing.
The Bottom Line: Choose Based on Risk Tolerance and Deal Economics
There’s no universally “better” structure. It depends on:
- What risks you’re comfortable taking
- How confident you are in the seller’s representations
- Whether critical contracts require consent
- Tax implications for both sides
- Market practice in your industry
The right choice is the one where both buyer and seller understand the trade-offs and have priced the deal accordingly.
