No fundraising round is planned to go down, but a down round — a new round priced per share below the previous one — is a normal part of startup life, and the moment every “just in case” clause in the earlier round’s documents gets truly tested. A foreign investor who entered a Vietnamese startup’s Series A at a USD 10 million valuation is usually shocked in two layers when Series B closes at 6 million: the first layer is their stake being marked down on paper; the second, more uncomfortable layer is that their ownership percentage dilutes far more deeply than they imagined, because a low issue price means the same new money buys many more shares. This article sets out what an earlier-round investor actually loses in a Vietnamese down round, how much of it the anti-dilution mechanism rescues, and the boundary between a market-driven price fall — for which nobody compensates anyone — and a fall caused by breached commitments, where the investor has a real claim.
What is lost: double dilution, a thicker preference stack, and the statutory preemptive right
The first loss is double dilution. When the new round’s per-share price is lower, the money raised converts into a larger number of shares; an earlier investor who does not join the new round sees their percentage drop much faster than in an up round raising the same amount. The second loss sits in the liquidation preference stack: new money at a cheap price commonly negotiates higher liquidation preferences and sometimes a senior ranking over earlier rounds, so when the company is sold at a modest price, what flows back to earlier shareholders shrinks from two sides — fewer shares, standing behind a thicker preference layer. What Vietnamese law gives an existing investor by default is not an anti-dilution clause but only a preemptive right: existing shareholders of a joint stock company have the preemptive right to buy newly offered shares in proportion to their existing ordinary shareholding under Article 124 of Enterprise Law No. 59/2020 (and members of a limited liability company likewise hold a pro-rata priority right when capital increases). This right lets the investor defend their percentage with their own money — if they still have money and conviction; it does not restore lost value and does not stop the company issuing at a low price. Every protection layer above the preemptive right — conversion price adjustments by full ratchet or weighted average, a minimum issue price veto, founder top-up shares as compensation — must have been written into the shareholders’ or investment agreement and the charter in the earlier round, because Vietnamese law does not generate them on the day the down round happens.
Who can be claimed against: the boundary between market risk and breached commitments
The law’s default answer to “can I claim compensation” is no: valuation is an outcome of the market and negotiation, and a low-priced round, by itself, is not a breach by the founders or the company toward earlier investors. Founders bear no personal liability for a fallen valuation — they are liable only in two situations with documents behind them. The first is where the cheap round is executed by breaching the very commitments given to earlier investors: issuing new shares without respecting the issuance consent or veto rights recorded in the shareholders’ agreement, failing to offer the preemptive right under the law and the charter, or breaking an agreed anti-dilution clause (for instance not adjusting the conversion price of the earlier investor’s preference shares although the trigger has occurred — the adjustment is executed through the preference-to-ordinary conversion mechanism for which Article 120 of the Enterprise Law provides the procedural frame). The second is fraud or distorted information in the earlier round: if that round’s high valuation was built on falsified financial data or customer contracts, the investor has grounds to claim damages and to have the transaction dealt with under the civil frame on deceived transactions — a dispute about conduct, not about price. And the decision “whether to follow the money in the down round” is a pure investment decision with its own arithmetic: new money today buys a large percentage at a cheap price (the most effective self-anti-dilution), but it may also pour more into an enterprise losing its market — pay-to-play clauses in later rounds increasingly use this pressure as leverage, and the investor should read that mechanism carefully before deciding to stand aside.
When a down round lands: five self-checks for the earlier investor
- Reopen the earlier round documents: is there anti-dilution (full ratchet or weighted average), has the trigger occurred, how is the conversion price adjustment written.
- Check whether the preemptive right under Article 124 of the Enterprise Law and the charter was properly offered — this is a statutory right, and bypassing it is an independent breach.
- Read the new preference stack: does the cheap round take seniority over yours, and at what exit price do you fall to zero.
- Classify the cause: a market price fall (nobody to claim against) versus breached commitments or earlier-round fraud (grounds to claim damages).
- Decide on following the money with cold arithmetic: today’s cheap price buys a large percentage, but only worth it if the business has a real path to live.
Frequently Asked Questions
The startup raises the next round at a lower price. What happens to my shares?
Two overlapping effects. The paper value of your investment is marked down to the new price (a valuation loss, often temporary on the books). And if you do not join the new round, your ownership percentage dilutes much more heavily than usual, because the same amount raised at a low price issues many more shares — dilution in a down round is always “thicker” than dilution in an up round of the same size. If your earlier round documents carry an anti-dilution clause, the conversion price of your preference shares is adjusted down (full ratchet: straight to the new price; weighted average: to a weighted average price), increasing the ordinary shares you receive on conversion and offsetting part of the dilution — the offset depends entirely on the agreed formula.
Is there any way to claim compensation when hit by a down round?
There is no claim merely because the valuation fell: price is a market outcome, and Vietnamese law does not insure investors against a low-priced round. A claim arises only with a specific breach: the company or founders issuing new shares against your consent rights or preemptive right under the shareholders’ agreement, the charter and Article 124 of the 2020 Enterprise Law; an agreed anti-dilution clause not being implemented; or your earlier round’s valuation having been built on fraudulent information, in which case the transaction can be dealt with under the civil deceit frame together with a damages claim. The right action when a down round is announced is to review these procedural and commitment breaches immediately, because many of these rights carry short objection windows tied to the issuance.
Are founders liable when the valuation drops?
No, under no general rule of Vietnamese law: founders do not guarantee the company’s future valuation, and a low-priced round caused by the market, declining business results or hard-negotiating new investors sits within the investment risk the earlier investor bears. Founder liability arises only from specific sources: personal undertakings they signed in the earlier round documents (for example a commitment not to issue below a price floor, a buyback undertaking, or a mechanism for founders to issue compensating shares when anti-dilution triggers); or independent misconduct such as providing fraudulent information in the earlier round, or using a cheap round to strip earlier investors’ rights against the agreement. If founders are to “be liable” in a down round, that liability must be drafted in the earlier investment round — it cannot be invented after the price has fallen.
Should I keep following the money in a down round?
It is an investment decision, but with a clear calculation frame. Following the money at a low price is the strongest anti-dilution: your money buys a materially larger percentage, keeps your preemptive position intact and preserves your standing in later rounds — many documents also carry pay-to-play clauses making standing aside cost your privileges. The other side: a down round is usually a signal the business is genuinely struggling, and following only makes sense where the price fell because of the general market or a fixable stumble, not a broken business model. The practical calculation separates two questions — “is this business still worth owning at the new price” and “what more do I lose if I stand aside” — and follows the money only when both answers lean toward paying.
