The merger vote is the key catalyst — monitor for the definitive proxy statement mailing and shareholder meeting date. The filing provides no new deal terms, so the stock price will likely trade on Zcash token price and broader crypto sentiment rather than HeartSciences' legacy medtech fundamentals. Watch for any dissident shareholder activity or competing bids given the small $12M market cap.
Price Chart
Executive Summary
HeartSciences filed a DEFA14A containing a transcript of a Fortitude Mining Holdings CFO's presentation at a Bitmain conference, promoting the Zcash mining thesis ahead of the all-stock merger vote. The filing is management solicitation material for the proposed business combination with Fortitude, a DCG subsidiary, which would transform HeartSciences from an AI medtech company into a Zcash mining platform. The presentation emphasizes Zcash's privacy features, improving fundamentals, and mining profitability, but provides no new financial terms or deal valuation for the merger.
Key Financial Metrics
Key Facts

- This DEFA14A includes a transcript of a Fortitude CFO presentation at the Bitmain Hong Kong Conference promoting Zcash mining economics.
- The filing is management solicitation material; a preliminary proxy statement was filed on July 27, 2026.
- Fortitude is a wholly owned subsidiary of Digital Currency Group (DCG), focused on Zcash mining.

Financial Impact
No financial figures for the merger (exchange ratio, valuation, pro-forma metrics) are provided in this filing. The presentation cites Zcash mining revenue of $0.70–0.80 per kWh and a $25M+ seed round for Zodl, but these are not HeartSciences-specific.
Risk Factors
- Merger may not close if HeartSciences shareholders do not approve the all-stock transaction.
- Post-merger business is entirely dependent on Zcash mining profitability, which is subject to extreme cryptocurrency price volatility.
- The filing notes risks including failure to obtain shareholder approval, integration challenges, and regulatory uncertainty around digital assets.
