A PPP BOT Vietnam acquisition — buying into an operating toll road, power plant or port concession — looks like a straightforward equity purchase once the project is built and generating cash. It is not. Vietnam’s PPP Law (Law No. 64/2020/QH14, effective 1 January 2021, as amended by Law No.
Quick summary — PPP BOT Vietnam:
- A PPP BOT Vietnam acquisition is blocked from transfer before construction completion under the PPP Law.
- PPP BOT Vietnam deals carry no statutory lender step-in right, unlike conventional project finance.
- Government consent in a PPP BOT Vietnam transaction is commercial leverage, not a formality.
57/2024/QH15 with effect from 1 January 2025) restricts transfer of equity in a project enterprise before construction completion, gives lenders no statutory step-in right on default, and leaves the post-completion secondary-transfer process to be worked out contractually and with the contracting state authority.
An acquirer who prices a PPP/BOT stake like a conventional infrastructure M&A deal — assuming lender consent and government approval are formalities — is pricing the wrong deal. This article sets out the structuring constraints, financing consequences and risk allocation for buying into an existing Vietnamese PPP or BOT project company.

1. PPP BOT Vietnam: The Pre-Completion Transfer Ban Most Acquirers Discover Too Late
The pre-completion transfer ban is the first thing to check on any PPP BOT Vietnam target.
Rule. The PPP Law restricts transfer of equity interest in the project enterprise to third-party investors before construction of the project is completed. Within a consortium, members may transfer stakes among themselves provided the lead investor retains a minimum equity ratio and other consortium members retain their own minimums, preserving the owner’s equity ratio approved for the project.
Application. A financial investor targeting a project still under construction cannot simply buy a stake from an outside consortium member; the only lawful route pre-completion is acquiring the interest of an existing consortium member, subject to the minimum-ratio rules. Acquirers sourcing deals through advisers who describe a pre-completion project as “available for acquisition” should treat that description as requiring immediate verification of construction-completion status and consortium structure.
Risk: Fatal Flaw if the target has not reached construction completion and the buyer is not an existing consortium member — the transaction is not structurable as described. Mitigation: confirm completion status and consortium membership before signing any exclusivity or term sheet; where completion is imminent, consider a conditional SPA that only completes post-certification of construction completion.
2. No Statutory Lender Step-In Right — What That Means for the Buyer
The absence of a statutory step-in right reshapes how lenders and buyers approach every PPP BOT Vietnam financing.
Rule. Unlike the earlier Decree 63 regime, the PPP Law removed the statutory step-in rights mechanism that allowed a project’s lenders to preserve essential project contracts on a project company default. In its place, on lender enforcement, the state authority and lending banks may work together to select a replacement investor by direct appointment — but the law does not fix a timeline or procedure for this.
Application. For a buyer acquiring into a project that is, or may become, financially stressed, this materially changes the downside case: there is no guaranteed contractual continuity mechanism if the existing project company defaults on its facility, only a discretionary, unscheduled state/lender process. Acquirers should not underwrite a distressed or near-distressed PPP asset on the assumption that a step-in mechanism will preserve value the way it would in jurisdictions with a codified step-in regime.
Risk: High for any target with covenant headroom concerns identified in financial due diligence. Mitigation: obtain direct confirmation from the project’s existing lenders (not just the seller) of facility status, covenant compliance and any waiver history before signing; do not rely on seller representations alone given the absence of a statutory fallback.
A PPP BOT Vietnam project often bundles industrial land assets as well — see industrial real estate M&A in Vietnam.

3. Government/Contracting-Authority Consent Is Commercial, Not Just Procedural
Underestimating the commercial weight of contracting-authority consent is the costliest mistake in a PPP BOT Vietnam negotiation.
Treating government consent as a commercial negotiation, not paperwork, is essential in any PPP BOT Vietnam transaction.
Issue. Beyond the PPP Law’s investor-selection provisions, a change of project-company shareholder structure post-completion typically requires engagement with the contracting state authority under the PPP contract itself — terms that vary project by project and are not standardised by the PPP Law. [State Authority Practice / Verification Required] — the specific approval procedure, timeline and any conditions the authority may attach (for example, technical capacity requirements for the incoming investor) should be confirmed against the specific PPP contract and the authority’s current practice before signing.
Mitigation. Build the authority consent process into the transaction timeline as a Condition Precedent with a defined outside date and a walk-away right, not an assumed formality; where the PPP contract gives the authority discretion over incoming-investor qualification, pre-clear the buyer’s technical and financial profile informally before committing significant transaction cost.
4. Pricing the Project-to-Equity Bridge
A disciplined PPP BOT Vietnam bridge separates completion risk from operating-phase cash flow before the buyer commits capital.
Pricing the project-to-equity bridge correctly is what separates a well-run PPP BOT Vietnam acquisition from an overpaid one.
Illustrative framework, not a specific project’s numbers. For an operating PPP/BOT asset, the standard bridge from project value to equity value for the acquired stake typically runs: Project (Enterprise) Value, based on discounted project cash flows or a comparable-transaction multiple → less outstanding project debt and any subordinated shareholder loans → less the present value of identified consent, step-in and regulatory risk (see §§1–3) → equals attributable Equity Value for the target stake.
Lenders and rating-style diligence typically also require Debt Service Coverage Ratio (DSCR) and Loan Life Coverage Ratio (LLCR) to be modelled under base, downside and severe-downside traffic/offtake or tariff scenarios, since revenue risk (traffic volume for toll roads, offtake volume for power, throughput for ports) is usually the single largest driver of equity value dispersion. Any acquirer relying on the seller’s base-case model without independently stress-testing the revenue assumption is pricing on an unverified number.
| Risk driver | Typical impact on equity value | Mitigation |
|---|---|---|
| Traffic/offtake below base case | Direct reduction to project cash flow and DSCR headroom | Independent traffic/demand study; price adjustment or earn-out tied to actual post-closing performance |
| Authority consent delay or condition | Delays closing; may require walk-away right | Condition Precedent with outside date; break-fee negotiated both ways |
| Absence of statutory step-in on lender enforcement | Increases tail risk if facility covenant headroom is thin | Direct lender confirmation; consider requiring refinancing or covenant reset as a closing condition |
5. Financing the Acquisition
Lenders underwriting a PPP BOT Vietnam acquisition facility will re-run the DSCR and traffic or offtake assumptions independently of the seller’s model.
Financing the acquisition of a PPP BOT Vietnam stake requires lender comfort with the transfer restrictions from day one.
An acquirer financing the equity purchase will typically be asked by its own lenders to demonstrate that the underlying project facility is not in default or covenant breach, and — given the absence of a statutory step-in mechanism — may face materially tighter loan terms than for an equivalent asset in a jurisdiction with codified lender protection.
Structuring a share pledge over the acquisition vehicle plus direct agreements (to the extent the existing project lenders will countenance them) is standard market practice; treat the project lenders’ willingness to enter into any direct agreement with the acquirer’s own financing bank as a diligence item, not an assumption.

The statutory framework for any PPP BOT Vietnam secondary transfer is the Law on Public-Private Partnership Investment 2020 (Law No. 64/2020/QH14).
FAQ
Buyers evaluating a PPP BOT Vietnam stake should treat the FAQ below as a pre-signing checklist.
Can a foreign investor acquire 100% of a Vietnamese PPP project company? This depends on the sector, the specific PPP contract’s investor qualification requirements and applicable foreign ownership conditions; it must be confirmed project by project rather than assumed from the PPP Law alone.
Does buying into a completed PPP project avoid the pre-completion transfer restriction entirely? Yes, the statutory restriction targets pre-completion transfers; post-completion transfers still require compliance with the PPP contract’s own change-of-shareholder provisions and any authority consent it specifies.
Why does the absence of a step-in right matter if the project is currently performing well? Because equity value should be priced on a risk-adjusted basis across the debt tenor, not only on current performance; a project with thin covenant headroom carries materially more tail risk without a codified step-in mechanism than an equivalent asset with one.
How long does authority consent for a shareholder change typically take? This varies by project and authority and is not fixed by the PPP Law; IVLF’s practice is to request the authority’s indicative timeline in writing before signing and to build a realistic buffer into the transaction schedule.
This article is general information as of its publication date and is not legal advice for a specific transaction. PPP contract terms, authority practice and lender arrangements vary by project.
Secondary M&A of Vietnamese PPP and BOT infrastructure assets turns on contract-specific consent mechanics and lender relationships that the PPP Law leaves to negotiation, not on the law alone. IVLF Advisors LLC coordinates legal, financing and authority-engagement workstreams as one transaction plan, so equity value is priced against verified consent and covenant status rather than assumed formalities.
