Capital B, the Paris-listed bitcoin treasury company once known as The Blockchain Group, will combine every 10 existing shares into one new share beginning September 8, according to a regulatory filing the company published Monday.
The consolidation reduces the number of outstanding shares from 300,650,632 to 30,065,063. Each new share will carry a par value of €0.80, up from €0.08 for the existing stock. The company framed the transaction as a “purely technical exchange” that leaves the aggregate value of each shareholder’s holdings unchanged, save for the treatment of fractional entitlements.
Capital B said the move aims to “support the company’s institutional development and to open the company’s shares to a broader universe of investors.”
Many institutional funds operate under internal rules that bar them from holding stocks below a set price, and some exchanges impose minimum-price thresholds for continued listing. A higher quoted price per share removes one barrier to that participation.
Capital B shares trade near €0.48 on Euronext Growth Paris and have declined about 40% since the start of the year, per Google Finance data. Should the company’s market value hold, each consolidated share would open near €4.80.
Key dates for Capital B shareholders
The reverse split period runs from August 6 through September 7. Shareholders who hold a number of shares divisible by 10 will see their positions converted with no action required.
Those holding leftover shares can buy or sell stock before the deadline to reach a round multiple of 10. For investors who do not, financial intermediaries will sell the shares tied to fractional entitlements and distribute the cash proceeds, with payments set to begin September 14.
September 7 marks the final trading day for the existing shares. The consolidated shares start trading the following day under a new ISIN, the code exchanges use to identify a security. The company has set September 9 as the record date and September 10 for settlement and delivery.
Capital B will also pause conversions of certain convertible bonds and exercises of share warrants from August 17 through September 10. After the split, the company will adjust conversion prices and warrant ratios to reflect the reduced share count, multiplying bond conversion prices by 10 while dividing warrant ratios and unvested free shares by 10.
Treasury strategy stays central
The share restructuring does not add bitcoin to the balance sheet or raise new capital on its own. It changes the number and nominal value of shares through a technical consolidation, a step the company tied to its goal of reaching a wider investor base.
Capital B’s bitcoin holdings
Capital B holds 3,139 BTC, a figure that ranks it as the second-largest listed corporate bitcoin holder in Europe, according to BitcoinTreasuries.net. Germany’s Bitcoin Group SE sits ahead of it with 3,605 BTC, the data shows. Capital B, which describes itself as Europe’s first bitcoin treasury company, built much of that position through fundraising rounds during the first half of 2026.
In May, it acquired 192 BTC for €13 million after completing three capital raises.
The company has moved to widen its access to capital. In June, shareholders approved authority for as much as €5 billion in capital increases and €100 billion in credit instruments, resolutions that drew more than 95% support from votes cast. Those approvals give the board financing capacity for future purchases.
Capital B measures progress through bitcoin held per fully diluted share rather than total reserves alone, a framework common among bitcoin treasury companies. The firm has also said it is developing a bitcoin-backed credit product for the European market, though it has not set a launch date.
