Capital B Share Regrouping Cuts Shares 10-for-1 to Attract Institutions

Capital B, the Paris-listed Bitcoin Treasury Company, has completed a sweeping restructuring of its share capital. Effective September 8, 2026, the Capital B share regrouping consolidates ten old shares into one new share, a move the company says is designed to attract institutional investors and widen its shareholder base on Euronext Growth Paris.

Key takeaways

• Capital B regrouped its shares at a ratio of 10 old shares for 1 new share, effective September 8, 2026, converting 382,506,040 old shares into 38,250,604 new shares.
• Old shares carrying a 0.08 euro nominal value were replaced by new shares with a 0.80 euro nominal value and full voting rights, trading under the new ISIN FR0014019Y19.
• Settlement-delivery of the new shares is scheduled for September 10, 2026, with proceeds from odd-lot sales distributed to shareholders starting September 14, 2026.
• Exercise and conversion rights for convertible bonds and stock warrants are suspended from August 17 to September 10, 2026, while their parities have been recalculated to reflect the new share count.

Capital B executes 10-for-1 share regrouping to bolster growth

The regrouping was carried out to support Capital B’s institutional development and to broaden the investor base tied to its stock, according to the company. Reverse splits of this kind are typically used by listed firms to lift a low nominal share value into a range that looks more familiar to institutional portfolios, and Capital B framed this operation in exactly those terms.

The company, which describes itself as the first Bitcoin Treasury Company in Europe and also runs subsidiaries focused on consulting and development in Data Intelligence, artificial intelligence and decentralized technologies, said the consolidation is meant to make its equity more accessible to a wider universe of investors rather than to change anything about its underlying business strategy.

New share structure and nominal values

Under the terms of the operation, 382,506,040 old shares with a nominal value of 0.08 euro each were exchanged for 38,250,604 new shares carrying a nominal value of 0.80 euro and full voting rights. The exchange ratio — ten old shares for every one new share — means the total number of shares in circulation shrank sharply while the overall nominal capital of the company stayed mathematically equivalent.

Trading timeline and settlement details

Trading in the old shares on Euronext Growth Paris stopped on September 7, 2026, the final session before the switch, while the new shares began trading on September 8, 2026, under the new ISIN code FR0014019Y19, replacing the previous code FR0011053636. The record date for the operation was set at September 9, 2026.

Suspension, resumption and settlement dates

Settlement-delivery of the new shares is scheduled for September 10, 2026, and Capital B has said no action is required from shareholders to receive the new securities. The exercise period for the company’s equity-linked instruments — convertible bonds and stock warrants — is set to resume the following day, on September 11, 2026, once the technical adjustments tied to the regrouping are finalized.

Convertible bonds and stock warrants adjusted for the split

Every conversion parity and exercise price tied to Capital B’s outstanding equity-linked instruments has been recalculated to account for the new share count, and holders will not be able to convert or exercise their rights until the adjustment period ends. This directly affects investors holding convertible bonds issued by Capital B Luxembourg SA and warrant holders across several tranches.

Suspension period and new conversion parities

The ability to convert convertible bonds into shares and to exercise stock warrants was suspended from August 17, 2026, at 00:01 Paris time until September 10, 2026, at 23:59 Paris time. Once the suspension lifts, conversion terms across the OCA A-03, OCA A-04, OCA A-05, OCA B-02, OCA B-03 and OCA B-04 convertible bond series, along with the BSA 2026-01 through BSA 2026-08 warrant tranches, will reflect the new ratio, generally requiring ten times the previous number of instruments to obtain one post-regrouping share.

Crypto.news, which tracks Capital B’s treasury activity, corroborated that the 10-for-1 consolidation took effect on September 8 and reported that exercise prices for the company’s newest warrant tranches were reset accordingly — €7.50 for Warrants 2026-06, €9.80 for Warrants 2026-07 and €12.70 for Warrants 2026-08 — each entitling holders to one-tenth of a post-split share. Holders of convertible bonds and warrants who end up with a fractional entitlement retain the option to pay a cash top-up to round up to the next whole share.

Odd-lot shares, company profile and risk factors

New shares that cannot be allocated on an individual basis, forming odd-lots, will be sold on the market by account custodians rather than left unresolved. The proceeds from those sales will then be distributed proportionally to the shareholders holding the odd-lot rights, with payments beginning on September 14, 2026. Shareholders with questions about how this affects their holdings are being directed to their financial intermediaries rather than to the company directly.

Capital B describes itself as a Bitcoin Treasury Company listed on Euronext Growth Paris under the mnemonic codes ALCPB in France and CPTLF in the United States, with subsidiaries specializing in Data Intelligence, AI, decentralized technologies and corporate treasury. The company has pointed investors to its 2025 annual report, available on its website, for a full description of the risk factors tied to its business, noting that the realization of those risks could affect its activity, financial position, results or development.

Why this matters for shareholders is straightforward: a reverse split changes the arithmetic of ownership but not its substance, yet it reshapes how the stock is perceived by institutional allocators who often avoid shares trading at very low nominal prices. For a company built around accumulating Bitcoin on a per-share basis, broadening the investor pool that can hold and trade the stock is arguably as strategically relevant as the treasury itself.
