Vietnam cross-border M&A transactions fail at diligence at a disproportionate rate — and the root causes are almost always structural and compliance-related rather than commercial. Understanding what sophisticated buyers actually look for changes how sellers prepare.
Why Vietnam M&A Transactions Fail at Diligence
Vietnam cross-border M&A transactions — particularly in fintech, digital assets, and financial services — fail at diligence at a rate that is disproportionate relative to comparable markets. The commercial terms are agreed. The strategic rationale is sound. The parties have alignment on headline valuation. Then diligence begins, and the transaction stalls, reprices, or fails entirely.
The root causes are almost never commercial. They are structural and compliance-related. Ownership structures that cannot be evidenced clearly. AML programs that exist in documentation but not in practice. Contracts with gaps that create contingent liabilities. Token-related assets with uncertain legal status. Data rooms that are incomplete, disorganised, or that raise more questions than they answer.
Sophisticated buyers — particularly those backed by institutional capital or operating in regulated jurisdictions — conduct diligence with legal and compliance teams that are looking for specific things. When those things are not present, or when the documentation suggests they are present but the evidence does not support it, the deal changes. Understanding what those teams look for is the starting point for sell-side preparation.
What Sell-Side Businesses Consistently Fail to Prepare
Beneficial ownership documentation is the most consistent failure. UBO chains that involve multiple jurisdictions, nominee directors, or layered holding structures need to be evidenced with clean documentation — articles of association, shareholder registers, nominee disclosure agreements, corporate certificates — that a sophisticated legal team can follow without gaps. When this documentation does not exist or cannot be assembled in the form required, diligence stalls at the foundational level.
AML program evidence is the second consistent failure. A policy document is not an AML program. An AML program is a policy document plus the evidence that the program operates as designed: transaction monitoring logs, alert handling records, STR filing history, training records, board-level compliance reporting. The absence of any of these components is visible immediately to a compliance team conducting diligence, and it raises questions about the entire program's operational effectiveness.
Contract completeness is underestimated consistently. Key commercial agreements — customer contracts, vendor agreements, employment arrangements, IP assignments — often have gaps that the business has never noticed because they have not mattered yet. Change-of-control provisions that were never negotiated. IP that was created by contractors without proper assignment. Employment arrangements that create successor liability. These gaps surface during diligence and require resolution that takes time the diligence timeline does not provide.
Token-Related Assets: A Specific Category of Risk
Vietnam's digital asset M&A landscape includes a category of risk that requires dedicated preparation: transactions involving businesses that have issued tokens, hold token-related assets, or have obligations arising from token structures. This is not a routine diligence category, and buyers' legal teams approach it with particular care.
The legal status of tokens in Vietnam remains unsettled in important respects. Transactions involving token-related assets require analysis of how those assets are characterised, what obligations they create, and whether those obligations transfer in a corporate transaction. Buyers will want certainty on these questions before closing, and the documentation required to provide that certainty needs to be assembled and structured with care.
Token-related liabilities — obligations to token holders, regulatory exposure arising from token issuance, contingent claims that have not been asserted — are areas where the gap between what the sell-side business believes its exposure to be and what a careful buyer's legal team identifies can be significant. Preparing this analysis before diligence begins, and being in a position to present it proactively, is materially better than discovering the gaps in real time.
How Pre-Transaction Advisory Changes Deal Dynamics
The difference between addressing compliance and structural issues proactively versus under diligence pressure is not primarily a question of cost — though the cost differential is significant. It is a question of deal dynamics and counterparty perception.
A sell-side business that enters diligence with a well-organised data room, clean UBO documentation, an AML program with an operational history, and contracts that have been reviewed and remediated presents itself as a well-run business. That perception supports valuation, maintains deal momentum, and builds the counterparty confidence that enables a transaction to close on the agreed terms.
A sell-side business that discovers its gaps during diligence — and attempts to remediate them under time pressure, while a counterparty's legal team is watching — signals operational and governance weaknesses regardless of whether the underlying business is sound. Valuations are adjusted to reflect the perceived risk. Timelines extend. And in some cases, counterparties decide that the remediation burden is too significant relative to the transaction value and the deal fails.
Krysos Trust's Experience as Sell-Side Counsel
Krysos Trust's founder acted as sell-side legal counsel on a USD 15 million crypto-sector M&A transaction in Vietnam. The engagement covered restructuring of the sell-side entity prior to the transaction, diligence preparation including data room construction and documentation gap remediation, negotiation of transaction documents, and post-deal support through the transition period.
That engagement demonstrated, in a specific transaction context, the issues that Vietnam cross-border M&A consistently produces: structural gaps that required remediation before the entity was in a condition to be sold, compliance documentation that needed to be strengthened before it could withstand institutional scrutiny, and the importance of sequencing — addressing the issues in the right order so that remediation in one area did not create problems in another.
The practical learning from that transaction informs Krysos Trust's approach to pre-transaction advisory: the issues that determine deal outcomes are knowable in advance, they are addressable with sufficient lead time, and addressing them proactively produces a materially better outcome than discovering them under diligence pressure. The investment in pre-transaction preparation is not a cost. It is a value protection measure.
