Company believes proposed Fortitude Mining Holdings business combination represents a significant value creation opportunity for the Company’s shareholders Fiscal 2026 saw the full commercial launch of the MyoVista Insights platform and submission of the MyoVista wavECG device to the FDA for 510(k) clearance Southlake, TX, July 29, 2026 (GLOBE NEWSWIRE) -- HeartSciences Inc. (Nasdaq: HSCS; HSCSW) ("HeartSciences" or the "Company"), a healthcare information technology ("HIT") company focused on advancing electrocardiography ("ECG" or "EKG") through the integration of artificial intelligence ("AI"), today announced that it has filed its preliminary proxy statement (the “Proxy Statement”) with the U.S. Securities and Exchange Commission (the “SEC”) in connection with the previously announced proposed business combination (the “Proposed Transaction”) with Fortitude Mining Holdings, Inc. (“Fortitude”) and is providing a business update and its financial results for the fiscal year ended April 30, 2026 (“Fiscal 2026”), which follow the filing of HeartSciences’ Annual Report on Form 10-K (the “Form 10-K”) for Fiscal 2026 with the SEC on July 23, 2026. Each of the Proxy Statement and Form 10-K is available at www.sec.gov and on the Company’s website at www.heartsciences.com. Fiscal 2026 and Business Highlights Fiscal 2026, and the period since, has been one of transformational change for HeartSciences. We believe the Proposed Transaction with Fortitude offers a compelling opportunity for our shareholders to own a stake in a company that is a meaningful part of the Zcash ecosystem. In our view, Zcash has been among the best-performing large-cap digital assets over the past year and is attracting growing institutional interest. In addition, we made significant progress, with the full commercial launch of its MyoVista Insights platform and deployment contracts with healthcare institutions, together with the submission of its MyoVista wavECG device to the FDA for 510(k) clearance, which is currently under review. Proposed Transaction with Fortitude Since the Company’s IPO in 2022 and despite significant commercial progress, the Company has experienced sustained pressure on its share price, has had to navigate repeated Nasdaq listing deficiencies and has often lacked the cash runway to make long-term strategic and operational decisions. Although the initial decision to evaluate strategic alternatives was, in part, a defensive one, the process that followed was not. The Company’s Board of Directors reviewed a range of potential alternatives and had genuine choices available. We chose Fortitude because we believe it is a highly attractive partner and the Proposed Transaction presents a significant opportunity for us to create both short- and long-term value for our shareholders, including for the following reasons: Zcash shares the foundational properties that have made Bitcoin compelling to investors but introduces enhanced privacy technology and quantum computing resilience. Fortitude is based, and operates solely, in the United States. Over many years it has developed into what is believed to be one of the largest and longest-tenured operators in the Zcash ecosystem, providing significant competitive advantage. In the six months ended June 30, 2026, it mined 72,696 ZEC, representing approximately 28% of overall ZEC production. Fortitude’s belief that its competitive positioning translates into meaningful benefits, including deep knowledge of mining ZEC at scale, status as a preferred buyer of mining equipment to support significant growth aspirations, and efficient and profitable mining operations. Fortitude has undertaken a number of actions to underpin growth, including its announcement yesterday of the energization of its new facility in Grand Island, Nebraska, which brings its owned power portfolio to over 60MW. The facility is expected to contribute to Fortitude’s planned trajectory of lowering its Zcash direct cash mining cost from approximately $70 per coin toward approximately $40 per coin, assuming successful equipment deployment and stable power, network, and market conditions. It has also executed purchase orders for a significant number of new machines with an expected payback of less than 12 to 18 months (assuming a hashprice of at least $0.021/kSol/day). Together, these advantages underpin a significant, business. At Zcash prices in excess of $500, Fortitude currently estimates that its run-rate adjusted EBITDA would be over $50 million, once new machines are delivered and hashing. Proxy Statement Our unaudited pro forma condensed combined statement of financial position set out in the Proxy Statement: assumes the issuance of approximately 107.6 million shares of our new to be designated Class V Common Stock to Digital Currency Group ("DCG"), the parent company of Fortitude, in connection with the Proposed Transaction; and shows our pro forma combined total shareholders’ equity of $70.0 million. The above is qualified in its entirety by reference to our unaudited pro forma condensed combined statement of financial position included in the Proxy Statement. Our shareholders will also note that the Proxy Statement includes a proposal to authorize our Board of Directors to complete, at its discretion, a reverse stock split, at a ratio to be determined by our Board of Directors and mutually agreed to by HeartSciences and Fortitude, within a range of between 1-for-2 and 1-for-5. This proposal is driven by Nasdaq listing requirements for the combined company if the Proposed Transaction is completed. Our Board of Directors currently expects that any reverse stock split would be implemented only if considered necessary to support the combined company’s Nasdaq listing in connection with the Proposed Transaction. Recognizing shareholder sensitivity around reverse splits, the ratio range has been carefully considered. Further details are available in the Proxy Statement (See Proposal 4). MyoVista Insights™ Healthcare IT Software Platform The past year saw MyoVista Insights move from an R&D project to full commercial application. We achieved product launch, version upgrades, Epic Toolbox designation and interoperability compliance, launched a first AI-ECG algorithm on the platform, and have begun deployments with a number of healthcare institutions. As we have consistently said, the field of AI-ECG is now moving forward at pace and has progressed significantly over the past 18 months. There have been multiple regulatory clearances of algorithms in the U.S. and internationally and the beginning of meaningful clinical use. We believe this validates our decision to focus on a cost-effective solution for cloud-based ECG management, which provides straightforward delivery of AI-ECG into today’s clinical workflows. In developing and commercializing MyoVista Insights, we are drawing on the successes of best-in-class radiology AI platforms and seeking to replicate those in ECG. The future strategy is straightforward: (i) add AI-ECG algorithms to the MyoVista Insights platform from world-leading algorithm companies with which we are in discussion; and (ii) convert the broad pipeline of ongoing customer discussions into further commercial contracts. MyoVista wavECG device HeartSciences submitted its MyoVista wavECG device to the FDA for 510(k) premarket clearance in December 2025, and the submission is currently going through the FDA review process. HeartSciences elected to separate the FDA submissions for the MyoVista wavECG device and its impaired cardiac relaxation AI-ECG algorithm following updated guidance published by the American Society of Echocardiography (“ASE”) regarding the assessment of Left Ventricular Diastolic Dysfunction (“LVDD”), including revised age-based thresholds for cardiac relaxation (e’). Fiscal 2026 Financial Results The Company reported no meaningful revenue for Fiscal 2026. As of April 30, 2026, the Company had approximately $1.7 million in cash and cash equivalents, and $0.2 million in shareholders’ equity. Complete financial results have been filed in the Form 10-K, which is available at www.sec.gov and on the Company’s website at www.heartsciences.com. Management Commentary “Fiscal 2026 was a year of transformational change for HeartSciences,” said Andrew Simpson, CEO of HeartSciences. “MyoVista Insights moved from development into full commercial use, with our platform launch, our first AI-ECG algorithm and commercial deployments with healthcare institutions, and our MyoVista wavECG device is under FDA review for 510(k) clearance. The proposed combination with Fortitude builds on that progress. It offers our shareholders continued ownership in a business operating at scale and generating meaningful revenue, anchored in Zcash, one of the best-performing large-cap digital assets of the past year. Fortitude is among the largest and longest-tenured operators in the Zcash ecosystem, and we believe the combination represents a significant value creation opportunity. We encourage all shareholders to read the Proxy Statement and look forward to their support at the special meeting.” For more information, please visit: https://www.heartsciences.com.

These forward-looking statements generally can be identified by the use of words such as “anticipate,” “expect,” “plan,” “will,” “would,” “believe,” “estimate,” “goal,” “intend,” and other words of similar meaning, but the absence of these words does not mean that a statement is not forward-looking. These forward-looking statements include, but are not limited to, express or implied statements relating to the timing and completion of the Proposed Transaction, the potential benefits of the Proposed Transaction, including access to the public markets and listing on Nasdaq, Fortitude’s plans and expectations concerning the Grand Island Facility including expected cost savings and other benefits, the timing and expected benefits of and the pay-back period related to Fortitude’s new mining machines, future plans for the MyoVista Insights platform, expectations related to the potential reverse stock split. All statements contained in this press release that do not relate to matters of historical fact should be considered forward-looking statements. These forward-looking statements are based on management’s current expectations and assumptions as of the date of this press release and are subject to a number of known and unknown risks, uncertainties, and other factors that could cause actual results to differ materially from those expressed or implied by such statements, including, without limitation, the following: the risk that the Proposed Transaction may not be completed on the anticipated timeline or at all; the failure to satisfy the conditions to the closing of the Proposed Transaction, including obtaining the requisite approval of the HeartSciences shareholders; market, macroeconomic, or other conditions that could adversely affect either HeartSciences or Fortitude, or the combined company; risks related to the integration of the two companies and the management of a newly public company; risks relating to Fortitude’s operations and business, including the highly volatile nature of the price of Zcash and other cryptocurrencies; risks related to Nasdaq review of the initial listing application of the combined company; risks related to the potential reverse stock split; and risks relating to significant legal, commercial, regulatory and technical uncertainty regarding digital assets generally. Additional factors that may cause actual results to differ materially from those expressed or implied by the forward-looking statements in this press release are discussed in HeartSciences’ preliminary proxy statement on Schedule 14A, filed with the U.S. Securities and Exchange Commission (the “SEC”) on July 27, 2026 in connection with the Proposed Transaction, HeartSciences’ 2026 Annual Report on Form 10-K, filed with the SEC on July 23, 2026, and other reports filed with the SEC from time to time. Readers are cautioned not to place undue reliance on these forward-looking statements. Each of HeartSciences and Fortitude expressly disclaims any obligation to update or revise any forward-looking statements, whether as a result of new information, future events, or otherwise, except as required by applicable law. All forward-looking statements are made as of the date of this press release. About Non-GAAP Financial Measures We have presented certain financial measures in this press release that are not recognized under GAAP. Specifically, we have presented “EBITDA” and “Adjusted EBITDA” (each as further described below). References to “EBITDA” mean earnings before interest, taxes, depreciation and amortization and “Adjusted EBITDA” means EBITDA, adjusted for non-recurring Proposed Transaction related expenses and non-recurring expenses including advisory, legal, accounting, and regulatory fees related to the spin-out of Fortitude’s business from Foundry in October 2024 to form a standalone business. We use non-GAAP measures in our operational and financial decision making and believe that such non-GAAP numbers are more representative of the performance of the business and thus instructive for our strategic planning. Specifically, with respect to Adjusted EBITDA, we believe it is useful to exclude certain items in order to allow for period-over-period comparisons on a more consistent basis and to focus on what we regard to be a more meaningful indicator for evaluating the underlying operating performance of the business. We believe that these non-GAAP financial measures, while not a substitute for GAAP financial measures, provide investors with (i) an improved ability to evaluate our underlying performance and (ii) greater transparency of the key performance metrics used by management with respect to operational and financial decision making. In evaluating Adjusted EBITDA, you should be aware that in the future we may incur expenses that are the same as or similar to some of the adjustments in such presentation. The non-GAAP financial measures presented herein are provided as supplemental information to our performance measures calculated in accordance with GAAP and should not be considered in isolation or as a substitute for GAAP. Non-GAAP measures have limitations as an analytical tool. Some of these limitations are: (i) Adjusted EBITDA excludes certain transaction-related expenses and non-recurring legal expenses we have incurred, such as litigation costs and one-time accounting charges; (ii) although depreciation and amortization are non-cash charges, the assets being depreciated and amortized may have to be replaced in the future, and the cash requirements for such replacements are not reflected in Adjusted EBITDA; (iii) the omission of the amortization expense associated with our intangible assets further limits the usefulness of Adjusted EBITDA; and (iv) Adjusted EBITDA does not include the payment of taxes, which is a necessary element of our operations. Because of these limitations, such non-GAAP measures should not be considered as an alternative to profit or loss for the period determined in accordance with GAAP or operating cash flows determined in accordance with GAAP. Management compensates for these limitations by not viewing the non-GAAP measures in isolation and specifically by using other GAAP measures to measure our operating performance. Further, non-GAAP financial measures do not have any standardized meaning prescribed under GAAP and therefore may not be comparable to other issuers. As a result, you should not consider such performance measures in isolation from, or as a substitute analysis for, our results of operations as determined in accordance with GAAP. With respect to projected full Fiscal 2027 Adjusted EBITDA, a quantitative reconciliation is not available without unreasonable efforts due to the high variability, complexity and low visibility with respect to purchase accounting adjustments, Proposed Transaction-related charges and legal settlement reserves excluded from Adjusted EBITDA. We expect that the variability of these items to have a potentially unpredictable, and potentially significant, impact on our future GAAP financial results.

Southlake, Texas, March 16, 2026 (GLOBE NEWSWIRE) -- HeartSciences Inc. (Nasdaq: HSCS; HSCSW) (“HeartSciences” or the “Company”), a healthcare information technology (“HIT”) company focused on advancing electrocardiography (“ECG” or “EKG”) through the integration of artificial intelligence (“AI”), today reported financial results for its fiscal third quarter ended January 31, 2026 (“FQ3 2026”) and provided a business update. Third Quarter and Recent Highlights During the third quarter and subsequent period, the Company continued advancing the commercialization of its MyoVista Insights™ healthcare IT platform and submitted its MyoVista® wavECG™ device to the U.S. Food and Drug Administration (“FDA”) for 510(k) premarket clearance. MyoVista Insights™ Healthcare IT Software Platform Regulatory classification. MyoVista Insights is classified as a Medical Device Data System (“MDDS”), which carries significantly lower regulatory requirements than medical devices and is exempt from FDA 510(k) clearance. As a result, organizational costs and time to commercial rollout are expected to be substantially lower and faster than those associated with regulated medical devices. Platform advancement. Since its early-adopter launch in 2025, the Company has implemented phased upgrades to MyoVista Insights. On March 13, 2026, HeartSciences released a significant version upgrade ahead of the American College of Cardiology (“ACC”) Annual Scientific Session, where the Company will exhibit and publicly introduce the platform to the broader cardiology and healthcare IT community. The upgrade includes mobile phone viewing, reporting enhancements, and significant interoperability improvements designed to support deployment across large health systems. Commercial traction. During 2026 the Company’s objectives include establishing key reference sites and generating initial revenues. HeartSciences has already made commercial progress with reference installations and endorsement from a hospital network. Early feedback has been compelling, and the Company is currently in discussions with multiple health systems regarding deployment. Management expects to announce several key customer wins during 2026. AI-ECG marketplace opportunity. In addition to generating per-test SaaS revenues as a secure cloud-based ECG data management system, MyoVista Insights is purpose-built to enable the integration of AI-ECG algorithms directly into routine clinical practice through an AI-ECG marketplace. The platform is designed to host third-party algorithms alongside HeartSciences’ own technologies. The Company is currently in discussions with several potential partners to host AI algorithms and believes this model positions HeartSciences to participate in a multi-billion-dollar AI-ECG market opportunity while reducing the cost and time required for algorithm development and regulatory clearance. Investor demonstration. Following the public introduction of MyoVista Insights at the ACC Annual Scientific Session, the Company plans to host an investor call to demonstrate the platform and provide additional detail regarding its commercialization strategy and market opportunity. MyoVista® wavECG™ Device The Company submitted its MyoVista wavECG device to the FDA for 510(k) premarket clearance in December 2025. HeartSciences elected to separate the FDA submissions for the MyoVista wavECG device and its impaired cardiac relaxation AI-ECG algorithm following updated guidance published by the American Society of Echocardiography (“ASE”) regarding the assessment of Left Ventricular Diastolic Dysfunction (“LVDD”), including revised age-based thresholds for cardiac relaxation (e’). Management Commentary Andrew Simpson, Chief Executive Officer of HeartSciences, said, “We are making strong progress toward our 2026 objectives, including establishing reference sites, commencing revenue generation for MyoVista Insights, making AI algorithms available on the platform, and achieving best-in-class interoperability across hospital systems.” Mr. Simpson added, “The submission of the MyoVista wavECG device to the FDA represents an important regulatory milestone and advances our broader strategy to modernize ECG through the integration of artificial intelligence.” Fiscal Third Quarter 2026 Financial Results HeartSciences reported no meaningful revenue for FQ3 2026 as the Company continues to focus on commercialization of the MyoVista Insights platform. As of January 31, 2026, the Company had approximately $3.4 million in cash and cash equivalents and $2.7 million in shareholders’ equity. Complete financial results are included in the Company’s Quarterly Report on Form 10-Q for the fiscal quarter ended January 31, 2026, which has been filed with the U.S. Securities and Exchange Commission and is available on the Company’s website at www.heartsciences.com.

Southlake, TX, Dec. 15, 2025 (GLOBE NEWSWIRE) -- HeartSciences Inc. (Nasdaq: HSCS) (“HeartSciences” or the “Company”), a healthcare information technology (“HIT”) company focused on advancing electrocardiography (“ECG” or “EKG”) through the integration of artificial intelligence (“AI”), today reported financial results for its fiscal second quarter ended October 31, 2025 (“FQ2 2026”) and provided a business update.

Southlake, TX, Sept. 11, 2025 (GLOBE NEWSWIRE) -- HeartSciences Inc. (Nasdaq: HSCS; HSCSW) ("HeartSciences" or the "Company"), an artificial intelligence (“AI”)-powered medical technology company transforming ECGs/EKGs to enable earlier detection of heart disease, today announced its financial results for the first quarter of fiscal 2026 ended July 31, 2025 (“FQ1 2026”) and provided a business update highlighting continued progress. First Quarter and Recent Highlights HeartSciences has made substantial progress during FQ1 2026 which saw the Company achieve an FDA Breakthrough Device Designation and successfully launched MyoVista Insights. MyoVista Insights™ Software Platform HeartSciences successfully developed and launched MyoVista Insights, a cloud-native software platform designed to modernize legacy ECG management systems and serve as a marketplace for AI-ECG algorithms. We have invested millions of dollars in the past 18 months to create a platform designed for use with existing ECG devices and to integrate into hospital EHR systems and existing clinical workflows while eliminating the need for a healthcare provider to purchase new ECG devices. MyoVista Insights has been designed to provide an AI-ECG marketplace to enable clinical institutions to access both HeartSciences’ and third-party AI-ECG algorithms from millions of ECG devices already in use globally. Importantly, the platform can be implemented onto existing ECG hardware infrastructure with no required capital expenditures, making adoption both seamless and cost-efficient. CPT reimbursement codes are now in place for AI-ECG which would cover algorithms provided by MyoVista Insights, using any compatible ECG device. These codes have been approved by CMS (Medicare) for billing are additive to conventional ECG test reimbursement. This enhanced reimbursement framework is expected to support AI-ECG adoption across the healthcare system by benefiting key stakeholders. Hospitals and institutions could increase revenue. Insurers could benefit from earlier interventions and save significant costs. associated with acute care Physicians could make better, earlier diagnosis. Most importantly, patients experience improved care outcomes. The platform began a phased rollout in May 2025, launching at early adopter reference sites. Phase 2 is anticipated to be launched alongside the Company’s first cloud-based algorithm for detecting reduced ejection fraction, which is targeted for FDA submission in the first half of calendar year 2026 with potential clearance later that year. Ultimately, the Company aims for MyoVista Insights to become the first cloud-native ECG management software stack, replacing outdated, on-premise solutions in a multibillion-dollar market. MyoVista® wavECG™ Device The MyoVista wavECG device is designed to host AI-ECG algorithm(s) as well as provide conventional ECG information. We are on track to submit under FDA 510(k) in the current calendar year. In July 2025, the American Society of Echocardiography (“ASE”) released updated guidelines for evaluating Left Ventricular Diastolic Dysfunction (“LVDD”), placing increased emphasis on cardiac relaxation (e’) and now requiring specific age-based threshold adjustments which increases its commercial value. Although we had incorporated age-based measures previously agreed upon with the FDA, we believe it is now prudent to update the algorithm to reflect the new ASE-published age-based measures. We initially anticipated making a single submission under two different product classifications. In light of the algorithm update, the Company now plans separate FDA submissions for the device and software algorithm to streamline review and accelerate potential clearance. This approach would also enable broader software deployment across both MyoVista wavECG and MyoVista Insights. Other Key Highlights The FDA granted Breakthrough Device designation for HeartSciences’ aortic stenosis ECG algorithm. The Company continued expanding its intellectual property portfolio, including a key U.S. patent covering the estimation of echocardiographic parameters via ECG. HeartSciences now holds 44 granted patents worldwide. Management Commentary “Our progress this quarter reflects both strong execution and a clear regulatory strategy,” said Andrew Simpson, CEO of HeartSciences. “The launch of MyoVista Insights has been well received, and by simplifying our submission pathway, we are positioning the Company to achieve regulatory clearances and initial revenues in 2026. The FDA’s Breakthrough Designation further validates our AI-ECG opportunity as we work to modernize legacy ECG systems and address the diagnostic gap in heart disease.” First Quarter Fiscal 2026 Financial Results HeartSciences reported no meaningful revenue for FQ1 2026. As of July 31, 2025 the Company had approximately $2.8 million in cash and cash equivalents, and $3.1 million in shareholders’ equity. Subsequent to FQ1 2026, the Company raised an additional $0.8 million through its ongoing Reg A+ offering and exchanged $0.7 million of debt into equity, further strengthening its balance sheet. Complete financial results have been filed in the Company’s Quarterly Report for the fiscal quarter ended July 31, 2025 on Form 10-Q with the U.S. Securities and Exchange Commission and is accessible via the Company’s website: www.heartsciences.com.

Southlake, TX, March 13, 2025 (GLOBE NEWSWIRE) -- HeartSciences Inc. (Nasdaq: HSCS; HSCSW) ("HeartSciences" or the "Company"), an artificial intelligence (“AI”)-powered medical technology company focused on transforming ECGs/EKGs to save lives through earlier detection of heart disease, today reported financial results for the third quarter fiscal 2025 ended January 31, 2025 and provided a business update. Third Fiscal Quarter 2025 Highlights: During the third quarter of fiscal year 2025 (“Q3 FY2025”) and to date in 2025, HeartSciences has seen material progress towards FDA submissions of our products and there have been significant positive developments in the AI-ECG field. A summary of the current status and key business highlights for Q3 FY2025 include: AI-ECG presents a generational opportunity to modernize the ECG industry, one of the most ubiquitous medical tests in the world. ECGs are generally decades-old devices, outdated technology and rely on legacy reporting and managements systems. By enhancing both hardware and software, HeartSciences enables earlier and more accurate detection of heart disease, bridging a critical diagnostic gap in frontline healthcare. HeartSciences is the only company building next-gen ECG device hardware, device agnostic cloud-native software and AI-ECG algorithms. Our versatility will enable us to deliver AI-ECG solutions across a variety of healthcare settings, ranging from large hospital systems to simple nurse-led mobile testing services. The final pre-submission meeting for the MyoVista® wavECGTM device took place with the FDA in February 2025 and we expect to finalize the FDA study clinical validation in a few weeks. Assuming this is successful, we anticipate submiting the device for FDA clearance within the first half of calendar 2025. The Company is in active discussions for MyoVista® InsightsTM to be implemented in test sites during 2025, which followed on-scheduled completion of Phase 1, in December 2024. MyoVista Insights is a cloud-native, cybersecure modern technology stack operating on a device agnostic basis for the millions of ECGs in place today. It is intended to radically upgrade ECG reporting and does not require regulatory clearance (as it is reporting based). Phase 2, which is subject to regulatory clearance, will add AI-ECG reporting. The Company has developed the system to provide both proprietary and third-party AI-ECG algorithms with the intention to function like an app store for AI-ECG. This will radically reduce the cost and regulatory burden on the Company in developing all of its own algorithms and ensure the Company can bring a broad panel of AI-ECG algorithms to clinical practice in an expeditious manner. HeartSciences is aiming for Phase 2 regulatory submission in the second half of calendar 2025 along with the first cloud-based algorithm (discussed below). Thereafter in Phase 3, HeartSciences intends for MyoVista Insights to serve as an ECG management system, a market valued in the billions of dollars. It is a necessity for all hospital systems worldwide to have an ECG management system. Current systems are generally dependent on decades-old IT architecture which are on-premise, server-based, lack flexibility and are costly for health systems. MyoVista Insights is a cloud-native application running on AWS, built to be much lower cost and provide considerably upgraded interoperability and cybersecurity In February, 2025 we successfully undertook pre-validation work with Rutgers Robert Wood Johnson Hospital System on the low ejection fraction (LVEF ≤ 40) algorithm licensed from Icahn School of Medicine at Mount Sinai, New York (Mount Sinai). We expect that this will be the first algorithm for FDA validation alongside the MyoVista Insights platform. The Company will now undertake final work and perform FDA validation studies using retrospective data with the aim of FDA submission in the second half of calendar 2025. Other notable highlights: HeartSciences’ MyoVista wavECG AI-ECG algorithm and many of the AI-ECG algorithms that would be delivered by the MyoVista Insights cloud platform were included in the CMS 2025 OPPS final rule, which became effective in January 2025. This enables appropriate reimbursement immediately upon commercial launch and is a significant milestone in AI-ECG being widely adopted. Management Commentary “This quarter has seen considerable across the board progress at HeartSciences. Following the meeting with the FDA in February, clinical validation for the MyoVista wavECG device is expected within weeks and, assuming it is successful, FDA submission would follow soon after in the first half of the year.” said Andrew Simpson, CEO of HeartSciences. “We successfully completed Phase 1 MyoVista Insights cloud-native platform on schedule, utilizing millions of dollars of investment. We undertook pre-validation of the low ejection fraction algorithm with Rutgers Robert Wood Johnson Hospital System. This is the first of severa algorithms licensed from the Icahn School of Medicine at Mount Sinai which we expect will be applied through regulatory clearance. It reinforces our belief that collaboration with Mount Sinai is enormously valuable.” “Feedback on MyoVista Insights cloud-native platform has been excellent, and we are in active discussion for early deployment in test environments. Our ultimate vision is to offer a path to modernize legacy ECG management systems, as they are generally inflexible and costly due to decades-old IT architecture. Instead, we will provide a next-gen, cybersecure cloud-native system to meet the sophisticated data driven needs of today’s health systems. Our AI-ECG marketplace will facilitate far quicker rollout of AI-ECG allowing patients and health systems environments to realize their significant benefits.” “Finally, and importantly, CMS has already established reimbursement for AI-ECG at a rate significantly higher than that of conventional ECG. We believe this further validates the clinical value of AI-ECG and highlights the significant commercial opportunity for one of the most widely used medical tests worldwide, with millions of ECGs are performed every week.” concluded Mr. Simpson. Third Quarter Fiscal 2025 Financial Results There were no revenues during Q3 FY2025. As of January 31, 2025, cash and cash equivalents were approximately $2.6 million and shareholders’ equity was approximately $1.8 million.
