Greenfield vs. M&A, factor by factor
| Factor | Greenfield | M&A |
|---|---|---|
| What you do | Establish a new Vietnamese entity and build operations | Buy shares/capital or acquire an existing Vietnamese business |
| Market entry | Slower; build licenses, team, premises, suppliers, and customers | Faster if the target is operational and properly licensed |
| Control | High from day one | High if you acquire control; shared if you buy a minority stake |
| Initial cost | Construction, recruitment, approvals, working capital | Purchase price plus transaction costs and integration capital |
| Legacy risk | Lower historical-liability risk | Potential tax, labor, regulatory, debt, litigation, land, and compliance liabilities |
| Existing assets | None unless you build them | Customers, brand, employees, contracts, permits, facilities, and local know-how |
| Cultural risk | You create the culture | You must integrate an existing organization |
| Best use | Manufacturing, logistics, technology centers, new brands, long-horizon projects | Consumer, distribution, regulated operations, established services, strategic local platforms |
Vietnam-focused guidance similarly describes greenfield entry as offering greater operational control but requiring more time and capital, while M&A can provide quicker access to existing infrastructure, customers, and operating capacity.
Choose greenfield if
Greenfield is the stronger route when:
- Your operating model, technology, controls, and culture are distinctive.
- You need a purpose-built factory, warehouse, office, data center, or service platform.
- Suitable acquisition targets are overpriced, opaque, or poorly managed.
- You have patient capital and can tolerate a longer pre-revenue period.
- You want to avoid inheriting historical tax, labor, environmental, or licensing problems.
- You need a wholly owned subsidiary rather than a business whose local relationships depend on the seller.
A new entity also makes it easier to design governance, accounting, employment practices, IP ownership, data controls, and compliance procedures correctly from the start. The tradeoff is that it begins with no customers, personnel, market reputation, or operating track record.
Choose M&A if
M&A is more compelling when:
- Time to market is critical.
- The target has licenses, facilities, permits, distribution channels, or government/customer relationships that are difficult to recreate.
- Local market knowledge and relationships are central to success.
- You need an established workforce or supply chain.
- The target has a strong brand or customer base.
- You can conduct rigorous legal, tax, financial, labor, environmental, and commercial diligence.
M&A should not be treated as simply "buying revenue." You are also buying the target's contracts, compliance history, employees, tax position, contingent liabilities, and sometimes unresolved disputes. A cheaper acquisition can become more expensive than greenfield once remediation, integration, working capital, and management replacement are included.
Vietnam regulatory overlay
As of August 2026, Vietnam's Investment Law 2025, Law No. 143/2025/QH15, is in force from March 1, 2026; provisions concerning conditional business lines took effect on July 1, 2026.
For greenfield entry, confirm whether the project requires investment approval, an Investment Registration Certificate, an Enterprise Registration Certificate, land or construction approvals, and sector-specific licenses. The exact route depends on the activity, project scale, location, foreign ownership, and use of land.
For M&A, foreign-investor registration may be required before changing members or shareholders when the transaction increases foreign ownership in a sector with conditional foreign market access, causes foreign investors to exceed 50% ownership in specified circumstances, or involves a target holding land in sensitive locations. Competition, securities, banking, insurance, real estate, and other sector-specific clearances may also apply.
Use this sequence
- Identify the asset you actually need. Is it a license, factory, customer base, distribution network, talent pool, brand, or simply a legal presence?
- Check whether the asset can legally transfer. Some permits, contracts, land rights, and regulated approvals may require consent, reissuance, or amendment.
- Compare time-adjusted cost. Include purchase price, taxes, transaction fees, integration, remediation, hiring, working capital, and the revenue lost during a greenfield build.
- Price control realistically. A minority M&A investment may provide less control than expected unless governance, reserved matters, board rights, management appointment, and exit rights are carefully documented.
- Stress-test the exit. Consider resale, buyout rights, strategic sale, IPO potential, liquidation, and restrictions on transferring foreign-owned interests.
Practical recommendation
- Manufacturing or infrastructure: favor greenfield unless an existing facility has unusually valuable approvals, location, utilities, or customers.
- Consumer goods, retail, and distribution: investigate M&A first because channels, brands, and local relationships may be the main value.
- Technology or professional services: greenfield is often preferable unless the target offers scarce talent, major contracts, or essential licenses.
- Regulated sectors: compare both routes only after a market-access and licensing review; an existing target does not automatically eliminate foreign-ownership or approval restrictions.
- Uncertain market demand: consider a staged entry — pilot through a local partner or minority investment, then build a greenfield platform after validating demand.
- Strong target but outdated assets: consider a brownfield strategy: acquire the company or site, then recapitalize, upgrade, and integrate it.
The default choice is therefore: greenfield for control and cleanliness; M&A for speed and embedded market access. For a new foreign operating business without a specific acquisition target, greenfield is generally the safer baseline; switch to M&A only when the target owns assets that would be unusually slow, expensive, or difficult to recreate.
