HeartSciences Inc. reports developments as a healthcare information technology company advancing electrocardiography through artificial intelligence. The company’s MyoVista Insights platform is a cloud-native, device-agnostic ECG management system designed for workflow efficiency, EHR interoperability and deployment of cleared AI-ECG algorithms in clinical workflows.
Recurring updates include commercialization of MyoVista Insights, customer and reference-site agreements with hospitals, health networks and academic programs, interoperability milestones such as Epic Toolbox designation, financial results and shareholder meeting matters. HeartSciences also discusses its MyoVista wavECG device, which is designed to provide conventional ECG functionality while supporting on-device AI-enabled solutions.
HeartSciences (HSCS) received FDA 510(k) clearance for its MyoVista wavECG device as a 12-lead resting electrocardiograph for healthcare facilities. Clearance K260005 covers ECG signal acquisition and interpretation in adult and pediatric patients, with interpretive statements provided to clinicians on an advisory basis. It does not include an AI-ECG algorithm. HeartSciences does not intend to commercialize the device without a cleared AI-ECG algorithm and has made no commercialization commitment or set a timeline.
The company plans to evaluate potential options for the device and its related intellectual property; its commercial focus remains on MyoVista Insights. HeartSciences expects its proposed business combination with Fortitude Mining Holdings to close in Q4 calendar 2026, subject to closing conditions, including approval by HeartSciences shareholders.
Fortitude, which plans to combine with HeartSciences (Nasdaq: HSCS), secured priority allocation for BITMAIN equipment through a non-binding purchase commitment. The letter of intent covers up to $100 million of next-generation Zcash mining equipment, with shipments expected to start in the second quarter of 2027. A binding purchase agreement depends on final specifications and pricing; purchases can be scaled down or increased subject to availability and BITMAIN’s consent.
DCG increased Fortitude’s credit facility commitment from $50 million to $70 million, leaving approximately $42.7 million available. Fortitude plans to borrow $20 million this week to pay a refundable deposit, expects funding in ZEC, and plans to sell it. After that borrowing, debt drawn would total approximately $47.3 million, with approximately $22.7 million remaining available. DCG may provide additional ZEC funding through FY 2027.
Fortitude Mining Holdings appointed Kimberly Pittman as Chief Legal Officer, effective September 28, as it prepares for a proposed business combination.
The previously announced combination is with HeartSciences (Nasdaq: HSCS). Pittman joins Fortitude’s executive leadership team and will oversee its legal function, advising management and the board on corporate governance, securities, regulatory, compliance, commercial and strategic matters.
Pittman brings more than 25 years of experience in corporate and securities law, governance and compliance. She most recently served as Chief Legal Officer, General Counsel and Secretary of ReserveOne. Previously, she was Vice President, Deputy General Counsel at HubSpot, with responsibilities including board advisory and mergers and acquisitions. She also held senior legal roles at SmileDirectClub and CBS Corporation.
Fortitude, proposed merger partner of HeartSciences (HSCS), amended its subsidiary’s DCG credit facility, raising the commitment to $50 million.
The commitment increased by $24 million from $26 million. Approximately $31 million of borrowing capacity remains, including approximately $7 million under the initial commitment, subject to facility terms. Parent company Digital Currency Group (DCG) may fund future loans in ZEC instead of cash. ZEC loans would be denominated and repayable in U.S. dollars, with the ZEC valued at transfer. Fortitude expects the remaining commitment to be funded in ZEC and intends to sell any ZEC received to finance mining equipment and facilities.
Fortitude anticipates drawing the approximately $7 million remaining under the initial commitment in ZEC before the end of September 2026. It plans to sell that ZEC to fund payments for previously announced 9,000-unit Zcash machine orders. Its combination with HeartSciences remains proposed, with trading under TUDE anticipated after completion.
Fortitude Mining Holdings (HSCS) appointed former Hut 8 chief executive Jaime Leverton as Chief Executive Officer, effective Monday, September 21, succeeding Andrea Childs, who will become Chief Operating Officer.
Leverton is expected to remain CEO after Fortitude’s proposed business combination with HeartSciences, with the combined company anticipated to operate under the Fortitude brand and trade on the Nasdaq Capital Market under ticker “TUDE”, subject to Nasdaq approval. Fortitude is a vertically integrated, Zcash-focused mining platform that mined 72,696 ZEC in the six months ended June 30, 2026, about 28% of network production, and reported second quarter revenue of $20.9 million. The company owns more than 60 MW of power across seven U.S. sites and has agreed to purchase 9,000 Antminer Z15 Pro units, adding about 7.56 GSol/s of Equihash hashrate with shipments expected in the fourth quarter of 2026.
HeartSciences (HSCS) reported fiscal first quarter 2027 results, detailed progress on its proposed business combination with Fortitude Mining Holdings, and provided a MyoVista Insights commercialization update.
For FQ1 2027, the company reported no meaningful revenue, a $2.9 million loss from operations (vs. $1.9 million in FQ1 2026), and a $3.2 million net loss (vs. $2.1 million), with a shareholders’ deficit of $2.0 million as of July 31, 2026. Results included about $0.5 million in incremental legal and professional costs tied to the Fortitude transaction, roughly $0.5 million of non-cash share-based compensation, and a $0.3 million inventory reserve related to the MyoVista wavECG device.
The proposed Fortitude merger is expected to close in Q4 2026, subject to conditions. HeartSciences signed its first US MyoVista Insights commercial agreements, added its first third-party FDA-cleared AI-ECG algorithm, expanded its patent portfolio to more than 45 granted patents, and raised about $2.2 million gross/net equity funding plus a $0.2 million debt-for-equity exchange after quarter end.
Fortitude, a vertically integrated digital asset miner anchored in Zcash, reported Q2 2026 revenue of $20.9 million and Adjusted EBITDA of $8.5 million, reconciled from a GAAP net loss of ($9.5 million). EBITDA was $4.9 million after adding impairment, depreciation, interest and tax effects.
The company mined approximately 33,646 ZEC at an average operating hash rate of 4.0 GSol/s and now controls 60+ MW of power capacity across seven sites. Fortitude highlighted progress toward a proposed business combination with HeartSciences (Nasdaq: HSCS), expected to close in H2 2026.
On August 12, 2026, Fortitude purchased 411,522 HSCS shares in a private placement for about $1 million at a $2.43 VWAP, a 22% premium to HeartSciences’ closing price, and now holds roughly 9.4% of HeartSciences’ outstanding common stock. The investment is intended to support HeartSciences’ operating expenses ahead of the Proposed Transaction.
HeartSciences (Nasdaq: HSCS; HSCSW) announced that on August 12, 2026, Fortitude Mining Holdings purchased 411,522 shares of HeartSciences common stock in a private placement for an aggregate of approximately $1,000,000. The shares were issued at $2.43 per share, a 22% premium to the closing price on the purchase date.
According to HeartSciences, the shares are standard voting common stock with no additional rights or preferences. The exchange ratio under the existing merger agreement between Fortitude and HeartSciences remains unchanged, and no extra shares will be issued to Fortitude equity holders at closing due to this investment. Following the transaction, Fortitude holds about 9.4% of HeartSciences’ outstanding common stock. The company stated that the investment provides additional working capital and strengthens its balance sheet ahead of the proposed business combination, which is expected to close in the second half of the current calendar year, subject to customary conditions including shareholder approval.
Fortitude Mining Holdings completed the cash-funded acquisition of a 12.5 MW digital infrastructure facility in Prosser, Nebraska, purchasing the underlying real property and improvements for a $6.25 million purchase price. Consideration included an approximately $985,000 hosting deposit credit and about $465,500 of T21 miners credited against the price, resulting in net new cash to close of roughly $4.7 million, reflecting prior power deposits.
The Prosser Facility becomes Fortitude’s third Nebraska site and contributes to an owned power portfolio of over 60 MW of contracted power across seven U.S. sites. According to Fortitude, the site offers an estimated stabilized power cost of about $0.045/kWh, full infrastructure ownership including a 67 kV substation, and participation in Southwest Power Pool market pricing and demand response programs. The company links this acquisition to its venture mining strategy and to building scale ahead of its proposed business combination with HeartSciences (Nasdaq: HSCS).
Fortitude Mining Holdings executed a definitive purchase agreement with Bitmain for 9,000 Antminer Z15 Pro Equihash ASIC miners, supporting its proposed business combination with HeartSciences (Nasdaq: HSCS). Units are scheduled to ship in two tranches: 3,000 in October 2026 and 6,000 in November 2026.
The per‑unit price is $3,499, for an aggregate equipment commitment of about $31.5 million/b. Fortitude believes this is roughly prevailing market pricing for comparable Q4 2026 batches. Based on Bitmain’s published specifications, the order represents about 7.56 GSol/s of incremental Equihash hashrate, to be deployed across Fortitude’s over 60 MW of contracted power capacity at seven U.S. sites.
For the six months ended June 30, 2026, Fortitude mined 72,696 ZEC, which the company estimates was approximately 28.0% of total network ZEC production, implying an annualized rate of about 146,730 ZEC (roughly 402 ZEC per day).
