The Blockchain Group announces a capital increase totalling ~€7.2 million at an average price of ~€4.49 per share as part of its “ATM-type” capital increase program with TOBAM to pursue its Bitcoin Treasury Company strategy

Puteaux, June 17, 2025: The Blockchain Group (ISIN code: FR0011053636, ticker: ALTBG) (the “Company”), listed on Euronext Growth Paris, Europe’s first Bitcoin Treasury Company, holding subsidiaries specialized in Data Intelligence, AI, and decentralized technology consulting and development, announces a capital increase under the “ATM-type” capital increase agreement with TOBAM (the “Program”) announced on June 9, 2025, to pursue its Bitcoin Treasury Company strategy, focused on increasing the number of bitcoin per share on a fully diluted basis over time.

Making use of the delegation of authority granted to him by the Board of Directors on June 11, 2025, itself acting under the 12th resolution approved by the General Meeting of Shareholders on June 10, 2025, the Company’s Chief Executive Officer decided on June 16, 2025, to carry out a capital increase for a total amount of €7,191,143.60 (including share premium), through the issuance of 1,603,306 new ordinary shares at an average subscription price of ~€4.49 per share.

On June 16, 2025, the Company combined into a single capital increase the subscription requests received from TOBAM between June 9 and June 13, 2025, and the subscription price has been determined in accordance with the terms of the ATM Agreement signed on June 6, 2025, namely:

The price for each request is equal to the higher of the closing price or the volume-weighted average price (VWAP) on the trading day preceding the request; andThe number of shares requested may not exceed 21% of the trading volume on the trading day preceding the request.

The shares issued will be admitted to trading on Euronext Growth in Paris (offer compartment).

The transaction does not require the preparation of a prospectus subject to approval by the AMF.

Given the high volatility of the share price observed since the signature of the ATM Agreement, the average subscription price of €4.49 represents a discount of 20.76% compared to the closing price on June 13, 2025.

Resolution of the shareholder’s general meeting

The Program initially established under the 5th resolution of the Company’s Extraordinary General Meeting of February 21, 2025, was implemented on June 16, 2025, in accordance with the 12th resolution of the General Meeting of Shareholders of June 10, 2025, which notably provides that the maximum nominal amount of capital increases that may be carried out under this delegation is significantly higher, having been raised to €500 million of nominal value. The 12th resolution adopted on June 10, 2025, replaces the 5th resolution of the February 21, 2025 general meeting.

Waiver of shareholders’ preferential subscription rights in favor of TOBAM

In accordance with the Program, the Chief Executive Officer has waived shareholders’ preferential subscription rights in favor of the investors to whom the offer is addressed, in the proportions set out below:
