Registration of Conversion of Class C Shares into Class B Shares in BTC AB

BTC AB said the Swedish Companies Registration Office has registered the conversion of 7,012 Class C shares into Class B shares under the company’s articles, reflecting a Q3 2025 increase in Bitcoin per Share (BPS) and corresponding to 20% of the BPS rise from listing through Sept. 30, 2025. The conversion, now executed, dilutes Class B share count by 0.9% and brings total outstanding Class B shares to 780,313, a modest increase that implements the firm’s BPS-linked conversion mechanism with limited immediate dilutionary impact on existing B-share holders.

Analysis

BTC AB announced that the Swedish Companies Registration Office registered the conversion of 7,012 Class C shares into Class B shares on 2025-12-11, a move the company linked to the third-quarter increase in Bitcoin per Share (BPS). The conversion corresponds to 20% of the increase in BPS from listing through 30 September 2025 and produced a 0.9% dilution of the total number of B-shares, bringing outstanding Class B shares to 780,313.

The conversion is an automatic, BPS‑linked governance mechanism disclosed in the Q3 2025 report, which operationalizes shareholder exposure to the company’s Bitcoin performance; the market sentiment signal is mildly positive and the immediate market impact is limited given the small dilution. Execution of the mechanism confirms management’s policy and provides a quantifiable link between underlying Bitcoin accumulation and equity supply changes, which can affect per‑share economics and voting composition over time.

Key implications for holders are that upside in BPS can trigger recurring conversions and incremental dilution at each measurement period, so future dilution risk is a function of continued BPS appreciation and the 20% conversion parameter. Investors should therefore track quarterly BPS disclosures, monitor aggregate share-class changes for liquidity and voting effects, and seek clarity from investor relations on the cadence and caps of future conversions.

Key Decisions for Investors

• Monitor the company’s quarterly BPS disclosures closely because future BPS increases will trigger the same 20% conversion rule and cumulative dilution,
• Treat this execution as a modestly positive signal of BPS growth but recognize the immediate dilution was small (0.9%); consider holding or modestly increasing exposure only if you expect continued Bitcoin accumulation,
• If you have material exposure, engage with investor relations for specifics on share-class voting rights and potential caps on conversions, and consider hedging or position sizing to manage the risk of recurring dilution
