Exail Technologies' €500m Convertible: How Acquisition Finance Preserves Cash, Creates Refinancing Claims and Transfers Repayment into Equity

When Exail Technologies priced €300 million of convertible bonds on 24 September 2025 — undated, unsubordinated, convertible into new shares and exchangeable for existing ones, ODIRNANE in the French market's abbreviation — and then added €200 million through a tap on 13 January 2026, the headline number told its investors almost nothing about what the company could now build. A nominal amount of securities is not buying power. What decides the capacity to act is a different set of quantities: the cash that actually crossed the boundary into the business, the portion already spoken for before it arrived, the claims the raise was meant to settle, and the form in which those claims will eventually be discharged. Those quantities diverge — not by accident, but because they are written into the terms of the instrument.

A convertible splits at issuance into an equity component and a financial liability; the liability carries a coupon and a reset formula, and a conversion right sits over the top. On Exail's €500 million of total nominal, the conversion corresponds to roughly 4.706 million share equivalents — a figure that is not a forecast of dilution, since adjustments can move the ratio, existing shares can be delivered instead of new ones, and the issuer may settle in cash, but a measure of the ownership channel the instrument opens. The same bond is debt now and potential equity later, and the "later" is governed by that ratio, not by the headline amount.

On 8 January 2026 Exail said its September 2025 convertible had received Euronext's European Defence Bond label, launched in July 2025 to direct private capital toward eligible European defence and security projects. A label changes how an instrument is marketed and who is willing to hold it; it does not change the arithmetic of how much cash reached the business or how the repayment will be discharged. The label is a distribution fact; the terms are still the asset.

So "raised €500 million" is really three numbers at once: gross proceeds, net new cash after fees and after any sums committed to refinancing existing claims, and a repayment obligation that may be met in cash, in new shares, or by conversion. The structure is a deliberate choice, and different issuers choose differently. Rheinmetall placed €1 billion of convertible bonds on 31 January 2023, in two tranches of €500 million, specifically to finance a large share of its acquisition of the Spanish ammunition producer Expal Systems. Same instrument family, opposite emphasis — and reading the terms is how you tell an acquisition financing from a liquidity cushion.

For an investor this is the difference between reading a press release and reading the instrument. Two companies that "raised the same amount" can have opposite capacity to act and opposite dilution paths, because the cash that arrived, the cash already committed, and the way repayment converts into equity are all set by terms the headline never mentions. None of it is hidden; it is simply not in the headline, and an issuer that wanted the market to see net spendable capacity would publish the four figures directly.

This analysis works through those mechanics deliberately, and leaves the reader with the questions that decide the money:

• How much of Exail's €500 million is net new cash, once fees and any pre-committed refinancing are stripped out?
• With the conversion equal to roughly 4.706 million share equivalents, what actually determines eventual dilution — and why is that figure not a forecast?
• In what form will the repayment be discharged — cash, new shares, or conversion through the ODIRNANE structure — and who bears each outcome?
• What does Euronext's European Defence Bond label change about who holds the bond, and what does it leave untouched in the terms?
