How it finances purchases: ATM and zero-coupon convertibles
The core of Capital B’s financial strategy is a mix of instruments designed to minimize dilution and preserve cash flexibility.
In particular, the company has initiated an “ATM-type” program, which involves gradual issuance of shares at prices in line with current trading, and has also utilized zero-coupon convertible bonds, which are debt instruments without a coupon with an option for future conversion into shares, thus keeping liquidity intact.
Having said that, this approach allows Capital B to seize market windows, reduce costs, and maintain a steady flow of purchases in BTC, with a leaner operational profile.
Inside the Mechanism: Price, VWAP, and the Role of TOBAM
In the structure of the ATM offering, the established price is the maximum among three benchmarks: the previous closing price, the daily VWAP (volume-weighted average price), and the VWAP calculated over the previous 20 days, discounted by 15%.
In this tranche, TOBAM subscribed to the entire offering: its Bitcoin Enhanced Fund positioned itself as the main buyer. Thanks to this mechanism, Capital B raised approximately €19.7 million without incurring brokerage fees, strengthening funding capacity with operations free from operational frictions.

However, without a prospectus detailing the starting point, composition, weights, and any leverage effect, this percentage cannot be independently verified and should be interpreted with caution, especially considering the intrinsic volatility of the underlying asset and the impact of subsequent issuances on capital.
