Capital B, the French Bitcoin treasury company, has secured another round of financing tied directly to its expanding Bitcoin holdings, this time with backing from Bitcoin pioneer Adam Back. The Capital B Bitcoin treasury strategy took a fresh step forward on Sept. 2 when the firm confirmed a €7.6 million private placement subscribed entirely by Back, a deal that could eventually push its BTC stack past 3,500 coins.
Summary
Key takeaways
- Through a private placement involving 13.18 million shares, Capital B secured €7.6 million in funding from Adam Back carrying warrants, at €0.58 per unit.
- The proceeds, combined with ongoing operations, could fund 376 more BTC, lifting holdings to 3,521 BTC from the current 3,145 BTC.
- Full exercise of the attached warrants could bring Capital B an additional €49.4 million.
- Back’s ownership stake will rise to 17.77% of ordinary shares post-issuance, and could climb to 27.8% if all warrants are exercised.
- A 10-for-1 reverse stock split takes effect Sept. 8, adjusting warrant exercise prices accordingly.
Adam Back private placement deepens Capital B’s Bitcoin bet
Capital B confirmed that Back subscribed to 13,181,030 shares, each bundled with four warrants, at €0.58 per unit, generating gross proceeds of €7.64 million. That subscription price carried a 15.4% premium over the company’s closing share price on Sept. 1, a detail that signals investor confidence rather than a discounted entry.
After fees and transaction costs, net proceeds are expected to land around €7.3 million. Capital B said the money will go primarily toward adding more Bitcoin to its balance sheet, extending a strategy built around growing BTC held per fully diluted share rather than simply expanding the company’s size.
This financing arrived just days after a separate private placement under identical €0.58 subscription terms, suggesting Capital B is running a fairly rapid, repeatable capital-raising playbook tied to its treasury ambitions.
What the new shares could buy
Proceeds from the placement, paired with the company’s ongoing operations, could fund the purchase of 376 additional Bitcoin. If that acquisition goes through, Capital B’s holdings would rise to 3,521 BTC.
The company currently holds 3,145 BTC, a total reached after buying five more Bitcoin for €280,000 in August at an average price of €55,882 per coin. That purchase pushed the aggregate acquisition cost of Capital B’s strategic reserve to €284.2 million.
The new shares from this transaction will be admitted to trading on Euronext Growth Paris once the deal closes. The warrants attached to them, however, will not be separately listed — only the ordinary shares created through future warrant exercises will eventually hit the market as they’re issued.
Bitcoin share warrants could unlock tens of millions more
The real financial upside for Capital B may not be the €7.6 million already raised, but what happens if the attached warrants get exercised. Each of the 13.18 million shares issued to Back carries four warrants split across three tranches, known as ABSA (shares with subscription warrants).
Two Warrants 2026-06 per share carry an exercise price of €0.75. One Warrant 2026-07 is priced at €0.98, and one Warrant 2026-08 sits at €1.27. All three warrant classes run on five-year maturities, giving Back — and by extension Capital B — a long runway to decide when and whether to convert them into fresh capital.
Capital B also retained the right to trigger an accelerated exercise period for any tranche if the 20-day volume-weighted average price of its shares climbs above 130% of that tranche’s exercise price for 20 straight trading days. Any warrants left unexercised once that accelerated window closes would simply become void.
If Back exercises every warrant tied to this transaction, Capital B stands to collect another €49.43 million. Broken down by tranche, the 26.36 million Warrants 2026-06 could generate €19.77 million, the 13.18 million Warrants 2026-07 another €12.92 million, and the same number of Warrants 2026-08 a further €16.74 million. None of that is guaranteed — it depends entirely on future decisions by warrant holders and how Capital B’s share price behaves — but it does represent a meaningful pipeline of potential funding well beyond the initial raise.
Adam Back’s growing stake and what it means for control
Back’s exposure to Capital B was already substantial before this deal. He held 54.3 million shares, equal to On a diluted basis, the figure reaches 12.31%, while 14.82% represents the ordinary share capital stake. Following the issuance of new shares from the Sept. 2 placement are issued, his position grows to roughly 67.49 million shares — pushing his ordinary ownership to 17.77% and his diluted stake to 14.76%.
Should every warrant from this transaction eventually be exercised, Back’s holding would jump to 120.21 million shares, representing 27.8% of Capital B on an ordinary basis and 23.36% on a diluted basis. That’s a significant concentration of ownership in a single strategic investor, and it raises a fair question about how much influence one shareholder could accumulate over a publicly traded Bitcoin treasury vehicle if all the warrant tranches convert over time.
Other shareholders remain part of the mix. Following the initial share issuance, Blockstream Capital Partners would command 18.91%, whereas public and institutional investors would hold the remainder together account for 53.43%. Executives hold 5.59%, with TOBAM at 3.18% and UTXO Management at 1.12%.
This matters beyond the cap table. A treasury company’s credibility with institutional investors often hinges on governance clarity — and a scenario where one backer could eventually control more than a quarter of the equity is the kind of detail analysts watching Bitcoin treasury stocks are likely to flag as the warrants mature.
Financing authority already in place
None of this is happening without a broader mandate. Capital B shareholders approved sweeping financing authority back in June, including the ability to raise up to €5 billion through capital increases and access up to €100 billion in credit instruments. Those resolutions passed with more than 95% shareholder support and now form the backbone of the company’s financing framework for its Bitcoin accumulation strategy.
Capital B reverse stock split adds a twist to the timeline
Closing of Back’s latest private placement is expected to begin Sept. 3, though Capital B cautioned that technical requirements could delay completion by a few days. Shares issued through the deal will carry the same rights as existing ordinary shares.
Layered on top of that is a separate corporate action: a 10-for-1 reverse stock split scheduled to take effect Sept. 8. Ten existing shares will be consolidated into one new share once the process is finalized.
That split has direct consequences for the warrants issued in this deal. After consolidation, each warrant will entitle its holder to one-tenth of a new Capital B share, and the exercise prices adjust accordingly — rising to €7.50 for Warrants 2026-06, €9.80 for Warrants 2026-07, and €12.70 for Warrants 2026-08. In practice, the economics of the deal don’t change, but the headline numbers investors see going forward will look very different.
A repeating pattern in Capital B’s Bitcoin treasury buildup
This isn’t an isolated move. The structure mirrors a €21 million private placement Capital B announced on Aug. 28, which involved 36.2 million shares carrying four warrants each and drew subscriptions from Back and TOBAM. That earlier raise, also priced at €0.58 per unit, generated an estimated €19.9 million in net proceeds and was expected to fund 270 BTC, moving holdings from 3,145 BTC toward Should all 144.88 million warrants tied to this placement be exercised in full, an additional 3,415 BTC could be obtained have generated another €135.8 million on its own.
Before that, in May, Capital B ran a similar €15.2 million private placement involving Back, TOBAM and other institutional investors, issuing more than 23 million shares with four warrants each at €0.66 per unit. Part of that capital was later deployed into a 192 BTC purchase worth €13 million, lifting holdings to 3,135 BTC at the time.
Taken together, these successive raises show a company leaning heavily on warrant-linked private placements as its primary fundraising tool, rather than debt or one-off equity sales. Each round dilutes existing shareholders to some degree, but each also comes bundled with optionality — warrants that only convert into cash if Capital B’s share price performs well enough to justify it. For a Bitcoin treasury company, that structure ties fresh capital to market confidence in both the stock and the underlying asset it’s accumulating.
