Ratchet, Liquidation Preference, Anti-Dilution: Founder's Anti-Trap Guide

You receive your first term sheet. The headline pre-money is in line with your expectations: EUR 12 m. You are ready to sign. Three months later, your lawyer explains that on the next round at the same valuation, you will lose 7 additional capital points without consideration. Six months later, on an exit at EUR 30 m, you will receive EUR 0.

This scenario is not a caricature. It describes the actual mechanics of three economic clauses that quietly turn an apparently reasonable term sheet into a trap: the liquidation preference, the anti-dilution ratchet and the participation right. None is illegal. None is intrinsically abnormal. All are negotiable — provided you understand what they do.

This operational guide describes the 2026 variants of these clauses, their quantified impact on the founder, and the line between an acceptable drafting and a suffocating one. It complements our French shareholders' agreement 2026: 15 essential clauses, which covers governance clauses, and our Startup valuation 2026: 5 methods to defend your price.

• Three economic clauses shape the real economics of a round: liquidation preference, anti-dilution (ratchet), participation right.
• A 1× non-participating liquidation preference is the 2026 French market standard for a clean seed and Series A. Beyond (2×, 3×, participating), the founder gives up value without genuine economic counterpart.
• A full ratchet triggered on a down round can dilute a founder by 5 to 15 capital points without any new investment from the fund. A broad-based weighted average is the acceptable norm.
• A term sheet is only a frame: the definitive drafting in the shareholders' agreement and the bylaws (preference shares, art. L.228-11 of the French Commercial Code) determines actual effect. A poorly drafted clause alone is worth several hundred thousand euros.
• In 2026, with more frequent down rounds, founders suffer these clauses more than they anticipate them. Upstream legal preparation has become the main protection lever.

A venture capital investor accepts asymmetric risk: cash now in exchange for a stake that may be worth nothing in 7 years. To rebalance the risk, they request two economic protections:

• a priority repayment guarantee in case of a poor exit or liquidation (the liquidation preference);
• dilution protection if the next round is at a lower valuation (the anti-dilution ratchet).

These clauses are not pathological in themselves. The problem arises with aggressive variants — those that turn risk protection into value capture. The founder's role is to distinguish legitimate protection from disguised capture.

In French law, these clauses are implemented through the creation of preference shares (article L.228-11 of the Commercial Code), whose features are defined in the bylaws and refined in the shareholders' agreement. For SAS structures, the bylaws framework is particularly flexible (articles L.227-13 to L.227-19), making it the dominant legal vehicle for French startups.

2.1. Definition#

The liquidation preference guarantees the investor priority recovery, on sale of the company, of a multiple of their initial investment before ordinary shares (founders, employees, BSPCE) receive anything.

Three parameters drive the effect:

• the multiple: 1×, 1.5×, 2×, sometimes 3×;
• participating or non-participating nature;
• any caps above which the investor stops participating.

2.2. 1× non-participating: the standard#

The investor receives either 1× their investment (recovery), or their pro-rata share of capital — whichever pays more. On exit, as soon as the sale value exceeds the fund's recovery multiple (typically 2 to 3× their cheque), the fund automatically converts into ordinary shares and gets its pro-rata.

This is the 2026 French market norm on a clean seed and Series A. It protects the investor on a poor exit (cash recovery) but does not pay them more than a founder on a successful exit.

2.3. 1× participating: the clause to watch#

The investor receives both 1× their investment and their pro-rata of capital — known as the "double-dip". Economic effect: at all exit levels, the fund captures an additional fraction that mechanically reduces the founders' share.

On a moderate exit (3 to 5× post-money), a 1× participating preferred reduces the founders' share by 5 to 15 points versus an equivalent non-participating.

2.4. 2× or 3× liquidation preference: exceptional regime#

Above 1×, you enter terrain that should be justified by exceptional risk on the investor side (turnaround, distressed companies, very volatile sectors). For a tech startup raising standard capital, asking for 2× or 3× is a negative signal — either the fund anticipates failure, or it is engaging in unjustified value capture.

In 2026, with more frequent down rounds, some funds attempt to impose 1.5× liquidation preferences on Series B repositioning. This practice, observed but not generalised, must be vigorously negotiated.

3.1. Definition#

Anti-dilution protects the investor against a later issuance of shares at a valuation lower than that of their round. Without this clause, a down round mechanically dilutes the investor. With it, their stake is adjusted to neutralise some or all of the loss.

Two families exist: full ratchet and weighted average. Their quantitative gap is huge.

3.2. Full ratchet: the suffocating version#

Full ratchet retroactively adjusts the investor's per-share acquisition price to the lowest price of any subsequent issuance. Concretely, if the investor bought shares at EUR 10 and the next round happens at EUR 5, their unit price is recalculated to EUR 5, doubling without further investment their share count.

Effect: a founder can lose 5 to 15 additional capital points on a down round, even as fresh money comes in. Full ratchet is rare in France in 2026 at seed, but appears occasionally on Series A proposed by foreign funds insufficiently acclimatised to the French market.

3.3. Weighted average: the balanced version#

Weighted average also adjusts the acquisition price but accounts for the relative volume between the old and new round. Two variants exist:

• Broad-based weighted average: includes total shares issued (capital + options + warrants). The founder-protective version.
• Narrow-based weighted average: includes only preferred shares. More investor-favourable.

On the same down round, where full ratchet dilutes the founder by 12 points, broad-based weighted average dilutes by 3 to 5 points. The structural difference is significant.

2026 standard: broad-based weighted average. The clause to demand.

Two additional clauses deserve special attention:

• Pay-to-play: the investor keeps preferential rights (notably anti-dilution) only if they participate in the next round at their pro-rata. This clause is founder-favourable: it aligns incentives.
• Automatic conversion on IPO: preference shares convert into ordinary on listing above a defined threshold. Essential for a future listing.

Conversely, certain penalising clauses should be flagged:

• liquidation preference cumulative with accumulated preferred dividends (rare in France but observed on Series B with foreign funds);
• minimum exit threshold below which the investor blocks any sale;
• veto right extended to all operational decisions, not just structural ones.

Common assumptions: Series A round of EUR 5 m at EUR 25 m post-money. Investor receives 20 % of capital. Founders hold 60 % before and after dilution. BSPCE pool 20 %. Exit 7 years later at EUR 30 m.

Scenario 1: 1× non-participating, weighted average#

On exit at EUR 30 m (1.2× post-money), the fund compares:

• recovery: EUR 5 m (1× their cheque);
• pro-rata: 20 % × EUR 30 m = EUR 6 m.

The fund picks pro-rata (EUR 6 m). Founders receive EUR 18 m (60 % × EUR 30 m).

Scenario 2: 1× participating, full ratchet#

The fund receives EUR 5 m (recovery) + 20 % of the residual (EUR 5 m) = EUR 5 m more, totalling EUR 10 m. If meanwhile a down round at EUR 15 m occurred, full ratchet has lifted the fund's stake from 20 % to 28 %, hence:

• recovery: EUR 5 m;
• pro-rata of residual: 28 % × EUR 25 m = EUR 7 m;
• total fund: EUR 12 m.

Founders: 60 % before down round, diluted to 48 % after ratchet, so 48 % × EUR 25 m = EUR 12 m (instead of EUR 18 m). Founder dead loss: EUR 6 m on the same exit.

This EUR 6 m gap reflects no additional risk taken by the fund. It reflects exclusively the drafting of two clauses in the shareholders' agreement.

Three complementary perspectives:

Perspective 1 — Accounting consistency of preference shares. Preference shares are not accounting-neutral. When they include a redemption obligation (liquidation preference) or a cumulative preferred dividend, they may be partially reclassified as financial debt under accounting standards (CNCC opinions and OEC doctrine). The reclassification affects the leverage ratio, any banking covenants, and how the balance sheet reads to future investors. A founder must anticipate the reclassification when drafting the bylaws.

Perspective 2 — Impact on future BSPCE valuation. Future BSPCE strike prices are anchored to the value of ordinary shares, not preference shares. If the liquidation preference is high, the gap between preference and ordinary shares widens, which lowers BSPCE strike prices and increases their attractiveness. A rarely emphasised but real effect.

Perspective 3 — Tax treatment of preference shares. In France, the sale of preference shares falls under the general capital gains regime (French Tax Code art. 150-0 A et seq.). International schemes (English or Delaware preference shares) may generate reclassification risks by the French tax authority, notably under abuse of rights. A French drafting remains preferable for a French company.

A frequent trap: the term sheet and the shareholders' agreement are drafted carefully, but the bylaws (which define preference shares under article L.228-11) are rushed. Yet, in case of conflict between agreement and bylaws, the bylaws prevail vis-à-vis third parties and the company.

Practical consequences:

• a liquidation preference written in the agreement but absent from the bylaws is unenforceable against a third-party acquirer;
• a ratchet clause in the bylaws without a detailed calculation mechanism can lead to lengthy disputes when triggered;
• subsequent changes to preference shares require the consent of the collective of preferred shareholders (article L.228-15), often forgotten in hasty drafting.

The reflex: read the bylaws before signing the term sheet, request synchronised drafting of the three documents (term sheet, shareholders' agreement, bylaws) by a venture capital specialist lawyer. Solid upstream legal advice typically costs EUR 5 to 15 k and prevents potential six-figure losses.

Six decisions to lock internally before the term sheet:

• Liquidation preference cap acceptable: 1× non-participating is the target.
• Non-negotiable anti-dilution type: refuse full ratchet, accept broad-based weighted average.
• Pay-to-play: systematically demand the clause.
• Cap on preferred dividends: refuse any uncapped cumulative dividend.
• Drag-along: minimum 60-66 % threshold (not 51 %), with a founder veto for exits below a defined valuation.
• Bylaws/agreement consistency: have all three documents validated by the same legal counsel before signing.

• More frequent down rounds — the 2025-2026 context shows more rounds at lower valuations. A poorly negotiated ratchet at seed becomes critical at Series A.
• 1.5× temptations — some funds test 1.5× liquidation preferences on Series B. Systematically refuse without operational justification.
• Imported "model" term sheets — beware of Anglo-Saxon templates used as-is by foreign funds: they often embed aggressive clauses (full ratchet, uncapped participating) that are not the French norm.
• ESG / CSRD compliance — some funds now embed ESG clauses on top of economic clauses. To frame carefully.
• Preferential subscription right (DPS) suppression (article L.225-138) — a poorly justified suppression can be challenged. Document the rationale.

• Identify the liquidation preference multiple and its participating / non-participating nature.
• Identify the anti-dilution mechanic (full ratchet, broad-based or narrow-based weighted average).
• Verify the presence of a pay-to-play clause.
• List preferred dividend clauses and any caps.
• List drag-along and tag-along thresholds.
• Verify investor veto clauses (reserved matters) and their scope.
• Verify the automatic IPO conversion clause.
• Identify founder vesting / reverse vesting.
• Compute effective dilution across 3 scenarios (exit at 1× post-money, 3×, 10×).
• Have term sheet / agreement / bylaws consistency validated by a specialist lawyer.

Is a 1× non-participating liquidation preference truly neutral for the founder?

Almost neutral on successful exits (the fund converts to ordinary as soon as it pays better). Slightly unfavourable on poor exits (1 to 1.5× post-money), where the fund recovers its cheque first. This is the 2026 market acceptable trade-off.

Is full ratchet illegal in French law?

No. It is lawful under freedom of contract and the flexibility of SAS bylaws (articles L.227-13 et seq.). But it is rarely justified on a clean deal and constitutes an unfavourable signal about the fund's intent.

What happens if the founder refuses to sign a full ratchet?

In 80 % of observed 2026 cases, the fund accepts a broad-based weighted average if the dossier is solid and competition exists between investors. In 20 % of cases, the fund holds: you must then assess whether the pre-money compensates or the deal should be abandoned.

Can preference shares be created without amending the bylaws?

No. Any creation or modification of preference shares requires an extraordinary general meeting decision and a bylaws amendment (article L.228-12). For SAS, the decision can follow the bylaws procedure, with the consent of the existing preferred collective for changes affecting their rights (article L.228-15).

How much does a term sheet legal audit cost?

Between EUR 5 and 15 k excl. VAT for a Paris venture capital specialist law firm, depending on dossier complexity and audit depth (term sheet, shareholders' agreement, bylaws). A structurally rentable investment given the amounts at stake.

Too many founders sign a term sheet thinking it will lock the valuation and they will negotiate the agreement later. The opposite is true. The term sheet sets the economic architecture; the agreement refines without correcting it. A founder who anticipates clauses upstream, with specialist venture capital legal counsel and a chartered accountant who measures the accounting and tax impact of preference shares, negotiates a radically different deal.
