Annual results

Consolidated income statement

(1) Adjusted EBITDA = Operating income before goodwill impairment + Net operating depreciation, amortization and provisions, including the Research Tax Credit (CIR)

It should be noted that the €62 million loss consists of a €54 million provision related to the impairment of BTC based on the price as of December 31, 2025, with no cash impact, and a
 €4.3 million of goodwill impairment, also with no cash impact.

The Group's total consolidated revenue amounted to €11.2 million, compared with €13.9 million for the same period of the previous year, representing a 19% decrease compared with 2024, mainly explained by staff turnover following the company's exit from judicial recovery proceedings.

The EBITDA (including CIR) of the Group's historical operating entities on a constant perimeter basis (IORGA Group and TRIMANE) amounted to €1.2 million*, representing an 88% increase compared with €0.65 million in 2024.

Group EBITDA amounted to (€2.7 million), due to costs incurred by the holding company Capital B (The Blockchain Group) and Capital B Luxembourg, including salaries and fees paid to financial intermediaries, amounting to nearly €4 million.

Purchases and other operating expenses amounted to €7.3 million as of December 31, 2025, compared with €5.5 million as of December 31, 2024, representing an increase of €1.8 million (+32%). This increase is mainly attributable to higher costs incurred in connection with the Bitcoin Treasury Company strategy, amounting to approximately €4.1 million.

Personnel expenses amounted to €10.3 million, compared with €11.6 million in 2024, representing a decrease of 11%.

The reduction in payroll costs is directly linked to staff turnover within the subsidiaries following the exit from judicial recovery proceedings.

Operating income before impairment of goodwill amounted to (€4.2 million), compared with
(€0.7 million) in 2024, due to costs incurred for the Bitcoin Treasury Company strategy.

Financial income amounted to (€54.2 million), compared with €0.2 million in 2024. Financial income includes the impairment of BTC held by the Group in an amount of €54 million as of December 31, 2025.

*Unaudited management data

Non-recurring income amounted to €0.5 million, compared with €2 million in 2024 (which included the capital gain from the disposal of the shares in the subsidiary Itaque).

Taking into account a €4.3 million impairment of goodwill, the Group's net income for the year amounted to (€62.2 million), compared with €1.4 million in the previous year.

Consolidated Balance Sheet

The Company's available cash amounted to €3.5 million, compared with €0.7 million as of December 31, 2024. The Group also holds 59 BTC allocated to its operational needs, representing ~€4.4 million, based on the Bitcoin price as of December 31, 2025.

The consolidated financial statements as of December 31, 2025 have been prepared on a going concern basis.

The Group's cash flow projections for the twelve months following the reporting date show a liquidity position consistent with its expected financing requirements over the period. These projections, which take into account the most recent business forecasts as well as the Group's bitcoin holdings, have been prepared based on assumptions aligned with the Group's new strategic direction.

Indeed, through the implementation of its Bitcoin Treasury Company strategy, the Group, that has greater available cash and a significant BTC reserve, is therefore less dependent on the operating performance of its subsidiaries, and has access to new financing resources.
