Capital B SA, the company formerly known as The Blockchain Group, announced a 10-for-1 reverse stock split that will reduce its outstanding shares from 300,650,632 to 30,065,063, with the new consolidated shares set to begin trading on September 8, 2026.

How the reverse split works

The par value of each share jumps from €0.08 to €0.80. That tenfold increase mirrors the consolidation ratio perfectly. Every shareholder who held 10 old shares will wake up on September 8 with 1 new share worth the same aggregate amount.

The exchange window for swapping old shares into new ones runs from August 6 through September 7, 2026. Trading of the consolidated shares kicks off the following day. The record date for the new shares lands on September 9.

Convertible bonds and warrants will be suspended from August 17 to September 10 to allow for post-split adjustments. Fractional entitlements will have those settled through market sales beginning September 14.

Why now, and why it matters

Capital B positions itself as Europe’s first Bitcoin Treasury Company. The company’s core thesis revolves around holding Bitcoin as a primary treasury asset while also operating in data intelligence and AI services.

The reverse split follows a rapid sequence of corporate moves. The company rebranded from The Blockchain Group to Capital B on June 17, 2026, the same shareholder meeting that granted the board authority to execute the consolidation. Just a month before that, on May 18, the firm announced a funding round of €1.1 million.

Many institutional investors have internal policies that prevent them from buying stocks below certain price thresholds. Some exchanges also impose minimum price requirements for continued listing. By boosting the share price through consolidation, Capital B removes one of the most basic barriers to institutional participation.

The Bitcoin treasury angle

Capital B’s positioning as a Bitcoin treasury company places it in a growing but still relatively uncrowded European niche. In the US, the Bitcoin treasury strategy has been pioneered most aggressively by companies like Strategy (formerly MicroStrategy), which has accumulated tens of billions of dollars worth of Bitcoin on its balance sheet.

Institutional investors don’t just care about price per share. They care about liquidity, float, and the perception of stability. A stock with 300 million outstanding shares trading at sub-euro prices looks speculative. The same company with 30 million shares at a higher price point looks like it belongs in a portfolio screening tool.

What investors should watch

Investors should pay attention to the convertible bond and warrant adjustments during the suspension period from August 17 to September 10. Post-split recalibrations of conversion ratios can shift dilution dynamics, and understanding how those instruments are repriced will matter for anyone modeling the company’s fully diluted share count going forward.
