Mistral's Koyeb Acquisition Split A €27.8m Exit Between Cash And Shares

Mistral AI's acquisition of Koyeb carried an implied equity value of approximately €27.8 million. About 36% of Koyeb was exchanged for Mistral shares, while the remaining 64% corresponds to an implied €17.7 million sale leg.

Those terms did not appear in the acquisition announcement. They appear in a French contribution report filed two days later.

The report turns one undisclosed acquisition into two different economic outcomes. Sellers in the sale leg crystallised value at the agreed Koyeb price. The parties who contributed shares kept exposure to Mistral, including the risk and potential upside attached to its next financing.

That distinction is especially important now. Samsung is reportedly in talks to invest about €1 billion in Mistral at a potential €20 billion valuation. If that round closes on those terms and the Koyeb rollover shares remain held, their paper value could be several times the €10.05 million assigned to them in February.

The Filing Puts A Price On The Deal

Koyeb announced on 17 February 2026 that it had entered a definitive agreement to join Mistral. The company said its serverless platform, technology and team would become a core part of Mistral Compute. Completion remained subject to closing conditions.

Contemporary TechCrunch coverage called it Mistral's first acquisition and said the financial terms were undisclosed. It also reported that Koyeb's three founders and 13 employees would join Mistral's engineering team.

The contribution report, signed on 18 February, supplies the missing price reference. Koyeb had 4,945,754 issued shares. Holders contributed 1,788,376 of them to Mistral at a total value of €10,050,673.12, exactly €5.62 per Koyeb share.

The report says the wider transaction combined a sale and a contribution under one Share Purchase and Contribution Agreement dated 13 February. It also says sold and contributed Koyeb shares received identical valuation treatment.

The table does not identify net proceeds. Transaction costs, taxes and recipient-level allocations remain outside the public filing. It does establish the deal's economic perimeter: approximately €27.8 million for all issued Koyeb shares, split between a roughly €17.7 million implied sale portion and €10.05 million contributed for Mistral equity.

The Terms Appeared One Day After The Announcement

The sequence matters because each public record answers a different question. Koyeb's announcement explains the product logic. The contribution report explains how part of the consideration worked.

The auditors were assessing the agreed contribution before every closing step had been completed. Their report says some contributors still needed to exercise subscription instruments and that the reality of the contribution could not yet be verified on the signing date.

That boundary does not weaken the price and structure recorded in the agreement. It fixes their status: agreed transaction terms, not a final post-closing cap table.

One Exit Created Two Economic Outcomes

The rollover block was not a symbolic sliver. At 36.16% of Koyeb's issued shares, it represented more than one third of the target at the same deal price used for the sale route.

In return, the contributing parties were due 906,266 new Mistral ordinary shares. The report records €10,050,489.94 of subscription value, which equals €11.09 per new Mistral share, plus a balancing cash payment of €183.18. The new shares were due to carry the same rights as Mistral's existing ordinary shares from completion.

That structure separated certainty from exposure. The sale leg fixed value at the Koyeb transaction price. The contribution leg exchanged that price for a stake in a much larger private company whose value could move with future financings, dilution and any later sale.

The public report keeps the contributors' identities and addresses confidential. Koyeb's founders, employees and investors may have had different allocations, but the filing does not support assigning cash or shares to any named person or fund.

For private-market readers, that missing schedule is now the decisive document. A headline acquisition price tells only how the target was valued. The allocation tells which sellers took liquidity and which continued underwriting the buyer.

The €20bn Scenario Changes The Rollover Math

Axios reported on 22 July that Samsung was considering an investment of about €1 billion at a potential €20 billion Mistral valuation. EQT Scaleup Europe was also reported to be in talks. Mistral's previous reported valuation was €11.7 billion.

The €20 billion figure is a negotiation, not a completed financing. It is still useful as a scenario because the contribution report identifies the exact Mistral share count issued for the Koyeb block.

The range depends on details that are not public: whether €20 billion is pre-money or post-money, how much Mistral issued between February and the new round, and whether the Koyeb recipients still hold all 906,266 shares.

If those conditions hold, the rollover route could have produced much more upside than the sale route within months. If the round closes at a lower valuation, includes heavy dilution or follows secondary transfers, the result changes. The same hybrid deal that preserved upside also preserved uncertainty.

Why Shares Fit Mistral's Compute Bet

The strategic case for using equity is straightforward. Koyeb brought a serverless deployment platform and a team already operating infrastructure for artificial intelligence applications. Mistral wanted that capability inside Mistral Compute as it expanded from model development into cloud infrastructure and enterprise deployment.

Shares can align an acquired team and selected investors with the buyer's longer-term build-out. Cash can give other holders a clean exit. The filing proves the split but not the motivation of any recipient.

The price also puts Mistral's infrastructure ambition in perspective. Koyeb had raised $8.6 million before the acquisition, according to TechCrunch. Mistral was not buying a large company by headcount. It was buying a compact platform and team that could accelerate a much larger compute strategy.

For venture investors, the result is a reminder that an acquisition headline can hide a second financing decision. The seller has to choose not only whether the target price is acceptable, but also whether the buyer's private shares offer a better risk-adjusted outcome than cash.

The Next Cap Table Decides The Outcome

The February report answers the first question. Koyeb's implied equity value was about €27.8 million, and 36.16% of its shares took the Mistral equity route.

The next Mistral capital certificate or post-closing shareholder record has to answer the harder one: whether those 906,266 shares remained with the original rollover recipients through the next financing, and what dilution and valuation actually applied.

Until then, the cash-versus-shares split is the durable finding. Mistral's first acquisition did not give every Koyeb seller the same exit. It divided a €27.8 million deal between holders who fixed their price and holders who kept underwriting Mistral.
