Capital B aims to add 376 BTC to bitcoin treasury following $8.8 million Adam Back investment

French investment firm Capital B is moving to bolster its corporate treasury with an additional 376 Bitcoin following a capital injection anchored by cypherpunk pioneer and Blockstream Chief Executive Officer Adam Back. According to a regulatory filing published on Wednesday, the Euronext Growth Paris-listed company secured approximately $8.8 million (€7.64 million) through a private placement explicitly structured to scale its digital asset holdings. The transaction illustrates the expanding geographical footprint of the corporate Bitcoin reserve strategy, bringing a model pioneered in North America into the heart of European capital markets. The financing mechanism relied on the issuance of 13,181,030 new ordinary shares priced at 0.58 euros per share. To incentivize long-term participation, each newly issued share carries four warrants, providing investors structured optionality on the company’s future equity valuation. The direct involvement of Back—whose Hashcash proof-of-work system served as a primary foundation for Bitcoin’s design—lends substantial narrative and strategic credibility to Capital B’s balance sheet transformation. His contribution provides the liquid capital required to execute the targeted 376 BTC acquisition at current spot prices, while reinforcing the validity of the corporate treasury strategy among crypto-native heavyweights. While treasury management strategies focused on Bitcoin accretion have predominantly featured U.S. firms like MicroStrategy or Asian entities such as Japan’s Metaplanet, European listed companies have traditionally taken a more conservative approach due to complex regulatory frameworks and fragmented liquidity. Capital B’s issuance signals a deliberate attempt to break from that mold. By deploying equity financing to accumulate non-sovereign reserve assets, the firm aims to convert its balance sheet into a proxy vehicle for investors who face mandate-driven restrictions on purchasing spot cryptocurrencies or exchange-traded products directly. The mechanics of the deal create a multi-stage capital generation model. The attached warrants offer a secondary funding engine: if the market responds positively to the Bitcoin acquisitions and drives Capital B’s share price higher, the subsequent exercise of those warrants will inject fresh capital into the business, enabling further purchases of Bitcoin without requiring entirely new placement rounds. This model is not without structural vulnerabilities. The upfront share creation causes immediate equity dilution for non-participating existing shareholders, and the company's long-term enterprise value becomes heavily levered to volatile crypto assets. If spot Bitcoin prices experience prolonged pullbacks, the euro value of the underlying treasury may fail to compensate for the expanded share count. Nevertheless, by securing institutional funding from prominent industry figures, Capital B is establishing a test case for whether public equities on continental European exchanges can successfully operate as hyper-financialized Bitcoin holding vehicles.
