Vietnam M&A Price Adjustment: Buyer and Seller Checklist
Vietnam M&A Price Adjustment clauses should match the target company’s accounting systems, working-capital cycle and closing data. Vietnam M&A Price Adjustment drafting must define leakage, debt, cash and normalized working capital.
A locked box Vietnam M&A structure can give price certainty, while completion accounts Vietnam may better capture closing changes. A qualified Vietnam M&A advisory lawyer can align the mechanism with dispute resolution and evidence requirements.

A carefully designed Vietnam M&A Price Adjustment mechanism reduces post-completion valuation disputes.
Vietnam M&A Price Adjustment mechanisms determine how much a buyer actually pays at closing versus what was agreed at signing, and getting this wrong is a common source of post-closing disputes.
The final price adjustment mechanism in an M&A transaction — locked box, completion accounts or earn-out — directly determines how financial risk between signing and completion is allocated, and is one of the most heavily negotiated points in any SPA.
This briefing, prepared by IVLF Advisors’ M&A advisory team, compares the three common price adjustment mechanisms and analyses the legal and accounting factors to consider when applying them in Vietnam.
Locked box: a fixed price set at a reference date
The locked box mechanism sets the purchase price based on financial statements at a historical reference date (the locked box date), prior to signing. The seller undertakes that no “value leakage” occurs — such as extraordinary dividends or off-market management fees — between the reference date and completion. This mechanism is common where the buyer trusts the quality of audited financial statements and wants to avoid post-completion disputes, but requires carefully drafted leakage protection and indemnity provisions.
Completion accounts: pricing determined after completion
The completion accounts mechanism sets the final purchase price based on financial statements prepared at or shortly after completion, typically adjusted for working capital, cash and debt at that date. This mechanism is fairer where there is a long gap between signing and completion, but adds cost and time for preparation, audit, and possible post-completion disputes over the accounts — requiring a clearly defined dispute resolution mechanism (usually via an independent accounting expert).
Earn-outs: tying part of the price to future performance
An earn-out defers part of the purchase price, tied to the target achieving specific financial metrics (revenue, EBITDA) over 1–3 years post-completion. This mechanism is useful where there is a significant valuation gap between buyer and seller expectations, but carries the highest dispute risk of the three mechanisms — particularly over whether the buyer operates the business in “good faith” to allow the earn-out targets to be met. The contract needs specific provisions on the seller’s/prior management’s operational control rights during the earn-out period.
Vietnamese accounting considerations (VAS)
Determining working capital, cash and debt under Vietnamese Accounting Standards (VAS) can differ from the IFRS conventions familiar to foreign buyers — particularly around revenue recognition, provisions and off-balance-sheet items. The SPA needs to clearly specify which accounting standard governs the completion accounts or earn-out metrics, and whether this is consistent with the company’s historical accounting policies.
Cross-border earn-out payments: foreign exchange considerations
Where the seller is offshore, post-completion earn-out payments must comply with foreign exchange management regulations under Circular 06/2019/TT-NHNN for indirect/direct foreign investment activity, depending on deal structure. Businesses should confirm the remittance mechanism in advance to avoid complications when the earn-out payment falls due.
Counsel’s view: In a Vietnamese M&A market where financial reporting quality varies significantly between companies, locked box should only be used where the buyer has completed thorough financial DD and trusts the most recent audited accounts; otherwise, completion accounts remains the safer choice despite taking longer.
Frequently asked questions
When should a buyer choose locked box over completion accounts?
When the buyer trusts the quality of audited financial statements and wants to avoid post-completion disputes, combined with strong leakage protection.
What is the biggest risk with earn-outs?
Disputes over whether the buyer operated the business in good faith to allow the earn-out targets to be met — operational control rights during the earn-out period need to be clearly defined.
Do completion accounts under VAS differ from IFRS?
They can differ on revenue recognition, provisions and off-balance-sheet items — the applicable standard should be specified clearly in the SPA.

Vietnam M&A Price Adjustment: Practical Takeaway
Choosing the right Vietnam M&A Price Adjustment mechanism means weighing the certainty of a locked box against the accuracy of completion accounts, or layering in an earn-out where valuation depends on future performance.
