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.
