European Bitcoin treasury company Capital B has secured €7.6 million in a private placement led by renowned crypto pioneer and Blockstream CEO Adam Back, signaling a major vote of confidence in the firm’s strategy of accumulating Bitcoin as a long-term reserve asset. The funding, structured as shares with attached subscription warrants, could fuel the purchase of up to 376 additional Bitcoin, lifting the company’s potential holdings to 3,521 BTC. The financing follows a previous private placement announced just days earlier under identical subscription terms of €0.58 per share. Net proceeds after fees and transaction expenses are expected to reach approximately €7.3 million, which Capital B plans to deploy primarily to add Bitcoin to its balance sheet, continuing a strategy focused on increasing BTC held per fully diluted share. Adam Back Joins Capital B’s Capital Table Adam Back, the inventor of Hashcash - a proof-of-work system that underpins Bitcoin’s mining mechanism - and CEO of Blockstream, has emerged as a strategic investor in Capital B. The deal marks Back’s direct involvement in a publicly traded Bitcoin treasury company, adding a layer of credibility to Capital B’s long-term accumulation strategy. Back is widely recognized as one of the most influential figures in the cryptocurrency space, having been cited in the original Bitcoin whitepaper. The €7.6 million placement consists of approximately 13.18 million shares, each carrying four subscription warrants (known as ABSA) divided across three tranches. The structure gives Back the option to participate in future capital raises at predetermined prices, with the potential to inject an additional €49.43 million into Capital B if all warrants are exercised. Detailed Breakdown of the Warrant Structure The warrants attached to the shares are structured across three classes with distinct exercise prices and maturities: Two Warrants 2026-06 attached to each share have an exercise price of €0.75 One Warrant 2026-07 can be exercised at €0.98 One Warrant 2026-08 carries a €1.27 exercise price All three classes have five-year maturities, expiring in 2026. Capital B can open an accelerated exercise period for a tranche if the 20-day volume-weighted average price of its shares exceeds 130% of the corresponding exercise price for 20 consecutive trading days. Unexercised warrants would become void at the end of an accelerated exercise period. If Back exercises every warrant issued through the transaction, Capital B would receive another €49.43 million, providing substantial additional firepower for Bitcoin acquisitions. Impact on Capital B’s Bitcoin Treasury Capital B currently holds 3,145 BTC after buying another five Bitcoin for €280,000 in August. The five coins were acquired at an average price of €55,882 each. The company reported an aggregate acquisition cost of €284.2 million for its strategic Bitcoin reserve after that transaction. Proceeds from the new placement, combined with Capital B’s ongoing operations, could support the purchase of 376 BTC. Completing the acquisition would increase the company’s potential holdings to 3,521 BTC. The table below summarizes the company’s Bitcoin accumulation trajectory: Treasury Metric Current Data Post-Placement Potential Bitcoin Holdings 3,145 BTC 3,521 BTC Additional BTC via Placement - 376 BTC Average Acquisition Cost (Aug. Purchase) €55,882 per BTC - Aggregate Acquisition Cost (Current) €284.2 million - Net Proceeds from Placement €7.3 million (est.) - Potential Additional Capital from Warrants - €49.43 million Strategic Rationale Behind the Move Capital B’s strategy mirrors the approach pioneered by MicroStrategy under Michael Saylor: using equity and debt financing to accumulate Bitcoin as a primary treasury reserve asset. The company has been steadily increasing its BTC holdings through a series of private placements, aiming to maximize the number of Bitcoin per fully diluted share. The involvement of Adam Back, a figure synonymous with Bitcoin’s foundational technology, adds a strong endorsement to this strategy. Back’s reputation as a researcher and developer - he is also the CEO of Blockstream, a company developing Bitcoin layer-2 solutions - could attract further institutional interest in Capital B’s shares. The warrant structure also provides a mechanism for Capital B to raise additional capital without issuing new shares immediately, giving the company flexibility to time Bitcoin purchases based on market conditions. Market Context and Broader Implications The news comes amid a period of relative stability in Bitcoin prices, with BTC trading in the range of €55,000 - €60,000 in recent weeks. Company treasury strategies that accumulate Bitcoin have become a notable trend among publicly traded firms, particularly in Europe and North America. Capital B’s decision to raise capital via a private placement rather than open market purchases reflects the company’s desire to lock in funding at a fixed price while offering investors a structured upside through warrants. The €0.58 per share subscription price represents a discount to the company’s recent trading levels, providing immediate value to participating investors. Observers note that the deal could set a precedent for other Bitcoin treasury companies seeking to partner with high-profile crypto figures to raise capital. Adam Back’s involvement may also signal growing interest from Bitcoin OG developers in the corporate treasury space, which has historically been dominated by traditional finance executives. What This Means for Shareholders Existing shareholders will see their holdings diluted by the new issuance, but the potential for significant Bitcoin accumulation could offset that dilution if Bitcoin prices rise. The warrant structure, if exercised, would provide additional capital for further Bitcoin purchases, potentially increasing the company’s BTC per share over time. Capital B’s management has emphasized that the primary use of proceeds is to add Bitcoin to the balance sheet as a long-term reserve asset. The company has not indicated any plans to sell its Bitcoin holdings, consistent with its stated strategy of holding through market cycles. How Much Bitcoin Does Capital B Currently Hold? Capital B currently holds 3,145 BTC after purchasing five additional Bitcoin in August 2024 at an average price of €55,882 each. The company’s aggregate acquisition cost for its strategic Bitcoin reserve stands at €284.2 million. What Are the Terms of the Private Placement with Adam Back? The placement consists of 13.18 million shares at €0.58 per share, each with four subscription warrants attached. The warrants are divided into three tranches with exercise prices of €0.75, €0.98, and €1.27, all with five-year maturities. If all warrants are exercised, Capital B would receive an additional €49.43 million. Why Is Adam Back Investing in Capital B? Adam Back, the inventor of Hashcash and CEO of Blockstream, is investing as a strategic partner. His involvement signals confidence in Capital B’s Bitcoin treasury strategy and could attract further institutional interest. Back is one of the most respected figures in Bitcoin’s history. What Will Capital B Do with the €7.6 Million Raised? The company plans to use the net proceeds of approximately €7.3 million primarily to purchase additional Bitcoin for its balance sheet as a long-term reserve asset. This could fund the acquisition of up to 376 BTC, increasing total holdings to 3,521 BTC. How Does the Warrant Structure Work for Capital B’s Financing? The warrants are attached to each share in three classes. Capital B can trigger an accelerated exercise period if the 20-day volume-weighted average share price exceeds 130% of the exercise price for 20 consecutive trading days. Unexercised warrants become void at the end of an accelerated exercise period.
