SUMMARY
With the support of:

Selling to an industrialist is a key moment in a start-up: one that crystallizes the value produced by the founders, employees and investors. The transaction is very often accompanied by a so-called earnout mechanism, especially in periods of strong economic uncertainty, such as the one we are going through following the health crisis. However, this mechanism is likely to have a decisive impact on the selling price. Therefore, it is essential to fully understand what you are committed to before entering into negotiations. This study is the result of a quantitative survey conducted with a sample of 89 members of the Galion Project who have completed at least one startup sale or takeover. It is complemented by qualitative interviews conducted with venture capitalists Jonathan Biggs (Accel Venture), Jean-David Chamboredon (ISAI) and Dominique Vidal (Index Venture).
What is an earnout?
In French, the expression that comes closest to it is “conditional price supplement”. The earnout thus combines two key concepts:
- It is a part of the sale price that is paid not at the time of signing, but at a later date.
- The amount of this additional price depends on the fulfilment of certain conditions.
There are two fundamental reasons for setting up an earnout:
- The first comes from the difference in the appreciation of the seller and the buyer about the intrinsic value of the company. In other words, the seller thinks that his startup is worth significantly more than what the buyer is willing to pay. In order to bring the points of view closer together, both parties agree that part of the price will be conditioned on the future performance of the company. This reduces the buyer's risk, while allowing the seller to capture all the value if the performance is good. From this point of view, the earnout is a compromise.
- The second reason is to make it a motivational tool for the founders of the start-up being purchased. In order to ensure that after the transaction, the team always wants to give as much as possible, the parties agree on goals whose achievement triggers additional financial rewards. From this point of view, the earnout is a carrot.
Is an earnout common practice?
Out of all the Galion start-up exits analysed, three-quarters of the deals contained an earnout. It is therefore a widely used tool in M&A transactions.
Intuition suggests that the earnout should be particularly relevant for small transactions involving start-ups with an economic model that is still uncertain. For more mature companies, it can be assumed that the buyer will have better visibility on the future. In this case, the use of an earnout is less justified. In practice, it can be seen that there is no correlation between the amount of the transaction and the presence or absence of an earnout. This is explained by the fact that a mature start-up generates much higher expectations and therefore that the valuation gap between the buyer and the seller is still there.
For Galion members who buy other start-ups (start-ups often buy each other out), the earnout only concerns two thirds of transactions. This can be explained in two ways:
- These are generally companies in the same sector that often know each other well, so assessing value is easier. On the other hand, the less familiar a company is with the activity of the start-up it is buying, the more it will tend to see in the earnout a kind of insurance against a poor initial valuation. In this regard, it is interesting to note that European corporates are much more keen on earnouts than American technology groups, the latter generally having a better ability to assess the strategic contribution of the acquisition.
- The vast majority of the transaction between startups is in unlisted shares, the spirit of which may be more like a merger than a formal takeover. All the parts are aligned to value the new set, there is no real need to add an additional motivation mechanism.
Who is the earnout for?
The earnout, which is a component of the selling price, should in principle be intended for all shareholders. In practice, this is far from always the case. Investors are in fact only included in the earnout in a quarter of transactions, the rest being reserved mainly for founders and more rarely for employees. This major trend can be explained by 3 reasons:
- Ensuring the post-transaction motivation of the operational team is at least as important as the risk-sharing aspect of the price.
- in general, venture capitalists try as much as possible to avoid earnouts (even if it means receiving a little less), because they know that they will have no control over it (unlike the founders). It is only for startups in difficult situations that they agree to enter the game. In these cases, as their investment has often already been written off in their books, the risk associated with the earnout is no longer so much of a problem.
- When he can, the purchaser will always seek to privilege his relationship with the founders rather than with the financial investors who, from his point of view, do not contribute anything to the future of the start-up. Moreover, this dynamic can create significant tension if the conditions offered to operational staff are clearly unbalanced compared to those offered to financial investors.
When the founders are the only beneficiaries of the earnout, this is generally conditioned not only on performance, but also on maintaining the founders in their operational function within the start-up. This makes it possible to combine risk sharing, motivation and talent retention.
When a start-up buys another start-up, the earnout is almost always meant only for founders. We can see that, in this case, the personal relationship between founders is a key element of the transaction.
What is the earnout amount?
The amount of the earnout compared to the total price of the transaction varies considerably from one deal to another. On the Galion start-ups analyzed, this is broken down as follows:

When a start-up from the Galion panel buys another start-up, the earnout also tends to be less significant and almost never exceeds half of the total price.
The greater the weight of the earnout in a transaction, the more it tends to be focused on the founders alone who have better control of the associated risk than financial investors. In parallel, we note that the weight of the earnout in relation to the total price tends to decrease with the size of the transaction. In fact, the greater the financial stakes, the more the seller wants to limit the volatility on his exit price.
What is the right length for an earnout?
Duration is of course a very sensitive subject for all parties. At first glance, sellers should aspire to an earnout as short as possible, while the purchaser follows the opposite logic. In reality, it's not that easy. After the transaction, there is a phase of integration into the buyer's organization: this process is often quite destabilizing for a start-up that is used to operating completely independently. The adjustment can therefore take some time before everyone finds their bearings. In fact, an earnout that is too short greatly increases the risk of missing the goals set. This is why in the majority of cases, we see that the parties opt for an earnout lasting at least 3 years:

The size of the deal has a strong influence on the duration of the earnout. The very short one-year earnouts were all applied to transactions of less than 20 million euros. On the other hand, for earnouts that last 4 years and more, there is a very strong over-representation of exits above 100 million euros.
On what basis should an earnout be calculated?
There are multiple ways to calculate an earnout. In the majority of cases, parties try to focus on one or two key financial indicators:

Unsurprisingly, profitability is the most used indicator. From the seller's point of view, this is the data that in fact gives the most flexibility: it can be achieved either by increasing turnover more quickly than costs, or by simply rigorously controlling expenses. From the perspective of the purchaser, this is the most natural indicator, since in the long term, any acquisition is expected to contribute to increasing the profits of the buying group. However, this profitability indicator can generate some perverse effects. A team that is too focused on a short-term profitability objective may in fact choose to deliberately underinvest, at the expense of future growth.
This is the reason why turnover growth is preferred in a good quarter of transactions. The volume of business is, in general, what has the most strategic value for the purchaser. That said, if he chooses this data, the purchaser will have to ensure rigorous cost control on the start-up to avoid the classic explosion of expenses aimed only at inflating the business in a non-sustainable way.
The combination of turnover and profitability may seem like the ideal compromise, but be careful not to complicate the calculation too much, at the risk of losing readability. The use of non-financial indicators is quite rare and concerns almost exclusively start-ups in the early stages.
How is the earnout amount determined?
Once the performance indicator is selected, two approaches to calculate the earnout stand out:
- The provisional business plan: the buyer and the seller agree on a provisional business plan with a target turnover or net result. If the objective agreed at the beginning is achieved, the earnout is paid.
- The mathematical formula: The amount of the earnout results from a simple calculation formula, typically a multiple of turnover or net income.
Of course, each approach has its pros and cons. To justify the transaction to its own shareholders, an industrial buyer must draw up a provisional business plan that is as rigorous as possible. So, it seems quite healthy to align the purchased team with its own strategic goals. The message is clear: if the objective is not reached, the earnout is not paid. On the other hand, if the planned objective is exceeded, it is entirely possible to provide an additional incentive, which is also observed in 30% of the deals analyzed in this study.
The main obstacle is that if, along the way, the provisional plan becomes out of reach, this can demotivate the founders, which is counterproductive for the purchaser. To overcome this, there are various mechanisms: partial payment on a partial objective, payment by instalments or even the possibility of deferring an objective that has not been reached. These various provisions can quickly make the clauses of the earnout very complex, which is in no one's interest... except of course the lawyers who write them!
In contrast, the mathematical formula has the great merit of being extremely simple. It is particularly attractive for a buyer who does not have a good appreciation of the real potential of the business he is buying. Based on a financial ratio that it controls, it also makes the transaction easier for its shareholders to understand. The problem is that we can find ourselves in configurations where, despite unachieved strategic objectives, the purchaser is obliged to pay a very significant earnout to sellers. In other words, by reducing the volatility of the earnout in case things don't go as well as expected, the mathematical formula tends to be more favorable to sellers. In case of great business success, one of the additional attractions of the mathematical formula for sellers is that, in principle, there is no limit to the amount of the earnout. In practice, in almost half of the cases studied, the purchaser nevertheless ensured security by stipulating a maximum ceiling on the formula.
Overall, both methods are used equally, but there are some factors that have an important influence on the choice. For example, we note that for deals where the stakes of the earnout are relatively low, the predictive business plan method is largely dominant. On the other hand, when the earnout represents an important part of the total price, the mathematical formula becomes the majority method. This is quite logical, since for deals where the earnout is an essential element in the remuneration of sellers, it is natural for them to limit their risk by ensuring that they receive a significant amount, even if the strategic objectives of the deal are not achieved.
The duration of the earnout affects the method chosen. For short earnouts (up to 2 years), the provisional business plan is almost always preferred. On the contrary, for a long earnout (4 years or more), for which financial forecasts become really risky, it is naturally the mathematical formula that becomes the arch-dominant tool.
For the start-ups on the Galion panel that buy other start-ups, the weight of the earnout is generally less important than in the case of an industrial purchaser, and is carried out over a shorter period of time. The business plan method is therefore widely preferred.
How is an earnout taxed?
For the founders, the great interest of the earnout (compared to a simple deferred payment) is that it falls under the favorable tax regime for capital gains. For the purchaser, the earnout is the joy of CFOs because, unlike traditional employee loyalty tools, it has the advantage of not impacting EBITDA.
To prevent the tax authorities from requalifying the earnout as salary income (which they have tried to do many times in the past given the important issues), you must ensure that the calculation of the earnout be directly correlated to the startup's activity, and especially that it is never guaranteed or certain. In this, the earnout is always more than just an additional price. If, as is often the case, the earnout is subject to the presence of the founders in the company, it is necessary to be particularly rigorous about the contingent nature of the earnout. To reinforce the solidity of the arrangement, the trend is to sell by installments. However, this approach can put off American buyers who, in general, like to be able to consolidate 100% of the startup acquired in the wake of the transaction.
Is the earnout always paid?
So much for the theory, but you still have to ask yourself the question of whether the earnout is a mirage or ultimately turns into hard cash. In this regard, there is a significant difference of appreciation on both sides of the Atlantic. Americans assume that an earnout is almost always paid in full, even if the performance targets are not met. In the latter case, they expect a legal dispute that will most often end in a transaction. Europeans, who have a less litigious culture, expect the earnout to be paid only in case of real achievement of the objectives. As a precaution, European venture capitalists almost always value the earnout at zero in their books, until they actually receive something.
In practice, it seems that Europeans have the right instinct to be cautious because, in the sample observed, the earnout was paid in full only in less than 40% of cases, which is quite consistent with the success rate of industrial acquisitions. In the sample observed, this full payment ratio is not correlated with either the size or the duration of the earnout.
On the other hand, the situation changes radically if the buyer is not a corporate but a startup from the Galion panel. In this case, the earnout is paid in full in 90% of cases. This dramatic difference can be explained by the fact that, since the motivation of the purchased founders is a key element in the success of the transaction, the parties most often demonstrate flexibility in objectives, so that an earnout improperly calibrated at the beginning does not damage the relationship.
To maximize the probability of success, it is also crucial to clearly clarify post-acquisition governance. For the purchased founders to really have control of their destiny, the startup must maintain a certain degree of management independence. At the same time, this independence is in contradiction with the desire of the purchaser to make use of the synergies between its historical activities and those of the startup being purchased. If poorly anticipated, these contradictory goals quickly lead to a lot of tension in the relationship. It is of course all the more complicated because the earnout extends over a long period of time.
So is an earnout a good thing?
At first glance, the earnout seems to be a necessary evil that is massively suffered by sellers who do not have enough bargaining power to require full cash payment at the signing of the transaction. But one can also see the earnout as a powerful tool, which allows a potential buyer to have the necessary comfort to complete a transaction. In this regard, it is symptomatic that almost half of the earnouts are established not at the time of the term sheet, but after due diligence during the final negotiation. In these cases, the earnout is most often the key that allows all parties to cross the finish line.
Certainly, the earnout introduces for the seller an element of uncertainty about the exit price that can be very significant. But the earnout can offer something even more important: the certainty of having an exit, a privilege that we often forget concerns barely 20% of funded startups.
Frequently asked questions about earnouts
What is an earnout?
An earnout, or contingent consideration, is the part of a start-up’s sale price paid after signing. Its amount depends on reaching targets agreed between seller and buyer. It serves both as a compromise when the two parties disagree on valuation, and as a way to keep the acquired founders motivated.
How long does an earnout usually last?
In nearly two thirds of cases (64%), the earnout lasts at least 3 years: the integration phase at the buyer makes a short earnout risky for the seller. One-year earnouts only apply to deals under €20M. Earnouts of 4 years or more are over-represented in exits above €100M.
How is the earnout amount calculated?
The parties choose one or two indicators: net income or EBITDA (35% of deals), revenue (25%) or both combined (25%). The amount is set either by a business plan, paid if the target is met, or by a formula, typically a multiple of revenue or net income.
How is an earnout taxed in France?
For founders, an earnout is in principle taxed as a capital gain, which is more favourable than salary income. To avoid the tax authorities requalifying it, its calculation must depend on the start-up’s performance and never be guaranteed. Extra care is needed when it is conditional on the founders staying with the company.
Is an earnout always paid?
No. In the sample studied, when the buyer is a corporate, the earnout was paid in full in less than 40% of cases. When the buyer is a start-up from the Galion panel, that rate rises to 90%, because the parties more readily adjust targets that were poorly set at the outset.
