NASDAQ: HSCS

On September 20, 2023, we entered into multiple definitive license agreements (each a “License Agreement” and collectively, the “License Agreements”) with Icahn School of Medicine at Mount Sinai (“Mount Sinai”) to commercialize a range of AI-ECG algorithms covering a range of cardiovascular conditions developed by Mount Sinai as well as a memorandum of understanding for ongoing cooperation encompassing de-identified data access, on-going research, and the evaluation of the MyoVista wavECG device. In June 2025 we received Breakthrough Device designation from the FDA for the aortic stenosis algorithm licensed from Mount Sinai.

Our future success is dependent upon receiving FDA clearances for our products and additional funding will be required as part of achieving FDA clearance and thereafter would be required to support the sales launch, provide working capital and support further R&D.

We believe that there is currently no low-cost, front-line, medical device that is effective at screening broadly for many types of heart disease. As a result, we believe that frontline physicians face a significant challenge in determining if a patient has heart disease. Although many think of the ECG as the frontline test for heart disease, in 2012, the United States Preventive Services Task Force conducted an evaluation of conventional ECG testing and stated: “There is no good evidence the test, called an ECG, helps doctors predict heart risks any better than traditional considerations such as smoking, blood pressure and cholesterol levels in people with no symptoms.”

ECG devices record the electrical signals of a patient’s heart. The ECG is a ubiquitous, relatively low-cost, simple and quick test; it is portable and can be performed in a wide range of clinical settings by a non-specialist clinician or clinical aide. There are three basic categories of heart disease: electrical (such as an arrhythmia), structural (such as valvular disease) and ischemic (such as coronary artery disease, or CAD). Conventional resting ECGs have limited sensitivity in detecting structural and ischemic disease and are typically used for diagnosing cardiac rhythm abnormalities, such as atrial fibrillation, or acute coronary syndrome, such as a myocardial infarction which

is also known as a heart attack. However, traditional ECGs have a limited role in identifying cardiac dysfunction associated with structural and ischemic disease.

HeartSciences has designed or licensed algorithms designed to help address these limitations and extend the clinical capability of an ECG to detect cardiac dysfunction and other heart disease types.

Our first AI-ECG algorithm to be incorporated into the MyoVista wavECG device has been designed by the Company and applies AI-machine learning to the signal processed ECG signal to develop a proprietary algorithm designed to detect impaired cardiac relaxation, or cardiac dysfunction, caused by heart disease and/or age-related cardiac dysfunction. In July 2025, the American Society of Echocardiography released updated guidelines for evaluating Left Ventricular Diastolic Dysfunction (“LVDD”), placing increased emphasis on the echocardiographic measure for impaired cardiac relaxation (e’) and now requiring age-based threshold adjustments. The device’s embedded impaired cardiac relaxation algorithm already incorporates age-adjusted measures, previously agreed with the FDA. HeartSciences is now evaluating alignment with the newly published standards prior to submission, with validation against our existing FDA study dataset still available.

The editorial comment associated with the study titled “Prediction of Abnormal Myocardial Relaxation from Signal Processed Surface ECG” presented below discusses recent applications of machine learning to data derived from surface 12-lead ECGs in relation to cardiac dysfunction:

“These represent some of the most significant advances in electrocardiography since its inception, which has historically had a limited, if any, role in the evaluation of cardiac dysfunction. In the past, our cardiovascular community was resigned to the fact that surface ECGs are poor indicators for cardiac dysfunction.”

Khurram Nasir, MD, MPH, MSC, Department of Cardiology, Houston Methodist DeBakey Heart & Vascular Center, Houston, Texas, et. al., Journal of American College of Cardiology Editorial Comment Volume 76 Number 8 2020.

Almost all forms of heart disease, including CAD and structural disease, affect heart muscle, or cardiac function prior to symptoms. Impaired cardiac function is first observed as impaired cardiac relaxation which is an early indicator of diastolic dysfunction and usually continues to increase in severity as heart disease progresses. The diastolic phase of the cardiac cycle occurs when the heart muscle relaxes (following contraction). Diastolic dysfunction may also be related to age-related cardiac dysfunction. Low ejection fraction, or systolic dysfunction, is a later stage of cardiac dysfunction and occurs when the heart pumps a reduced level of blood from the ventricles during contraction.

We expect the first AI-ECG algorithm to be submitted as part of the MyoVista Insights Cloud Platform will be for the detection of low ejection fraction, or systolic dysfunction, based on one of the licensed algorithms from Mount Sinai.

If we receive FDA clearances for our product candidates, our main target markets would be frontline healthcare environments in the U.S., to assist physician decision making in the cardiology referral process. Currently, cardiology referral decisions are often based on a patient’s risk factors and/or a conventional ECG test. Accordingly, many patients with heart disease are left undetected while no current treatment or intervention is required for most patients referred for cardiac imaging. We believe that adding the capability to detect a broader range of cardiac conditions to the standard 12-lead resting ECG could help improve cardiac referral pathways and be valuable for patients, physicians, health systems and third-party payors.

New Class II devices, such as our products, require FDA premarket review. The MyoVista wavECG device along with its proprietary software and hardware is classified as a Class II medical device by the FDA. Premarket review and clearance by the FDA for these devices is generally accomplished through the 510(k) premarket notification process or De Novo classification request, or petition process. We previously submitted an FDA De Novo classification request in December 2019 and, following feedback and communications with the FDA during and since that submission, we have been making modifications to our device, including our proprietary algorithm. We have finished the patient recruitment and core lab work for our FDA validation study and have been undertaking device and algorithm development testing for a revised FDA submission. We had been planning a revised submission under

the De Novo pathway, however, in December 2023 the FDA confirmed that we could submit the MyoVista wavECG device for clearance under the 510(k) pathway following the grant by the FDA in August 2023 of an industry-first De Novo clearance which created a new Class II product code for cardiovascular machine learning-based notification software. This was in respect of a hypertrophic cardiomyopathy algorithm and in late September 2023, the FDA cleared an algorithm for low ejection fraction (less than 40%) under the 510(k) pathway using this new product code. We have been preparing for a 510(k) FDA submission in calendar 2025. However, in July 2025, the American Society of Echocardiography released updated guidelines for evaluating LVDD, placing increased emphasis on the echocardiographic measure for impaired cardiac relaxation (e’) and now requiring age-based threshold adjustments. The device’s embedded impaired cardiac relaxation algorithm already incorporates age-adjusted measures, previously agreed with the FDA. We are now evaluating alignment with the newly published standards prior to submission. If successful, FDA clearance would provide us the ability to market and sell the MyoVista wavECG device in the U.S. and additional funding would be required to support the sales launch of the MyoVista wavECG device in the U.S., provide working capital and support further R&D.

To date we have not yet entered into a discussion with the FDA regarding the MyoVista Insights Cloud Platform or Mount Sinai licensed AI-ECG algorithms but are aiming to start that process in the current calendar year. We expect these products to fall under the 510(k) pathway and are aiming for an FDA submission of our MyoVista Insights Cloud Platform and low ejection fraction algorithm during the first half of calendar year 2026.

Heart Disease Facts and Current ECG Testing Limitations

Heart disease refers to a variety of conditions that affect the heart — including heart rhythm problems, heart valve problems, genetic defects and blood-vessel diseases such as CAD. It is often referred to as the “silent killer.” According to the American Heart Association, one in three patients are not properly diagnosed until after a heart attack occurs and 50% of men and 64% of women who died suddenly of coronary heart disease showed no previous symptoms. Statistics published by the U.S. Centers for Disease Control and Prevention (the “CDC”), show that in the United States, heart disease is the leading cause of death for both men and women, across most racial and ethnic groups. According to the CDC, in the United States, one person dies from cardiovascular disease every 34 seconds. In 2020, about 20.1 million adults aged 20 and older in the United States have CAD (about 7.2%), with approximately one in five heart attacks being a silent heart attack therefore the person is not even aware of it, but the damage is done. Approximately 695,000 people in the U.S. died from heart disease in 2021: that’s one in every five deaths. The scale of the problem is similar worldwide. In 2020, the World Health Organization confirmed that heart disease has remained the leading cause of death at the global level for the last 20 years. Cardiovascular diseases are the leading cause of death globally. An estimated 17.9 million people died from cardiovascular diseases in 2019, representing 32% of all global deaths.

The 2019 National Ambulatory Medical Care Survey showed there were approximately 1 billion ambulatory care visits in the U.S. with a high incidence of patients with risk factors for heart disease (33% had hypertension, 15% had diabetes and 7% had a history of CAD, ischemic heart disease or myocardial infarction).

As heart disease progresses to more acute stages, the cost to treat patients increases significantly. Cardiovascular disease is the leading cost to the healthcare system and is estimated to be responsible for one in every six healthcare dollars spent in the United States. Heart disease cost the United States about $240 billion in each of 2018 and 2019, including the cost of health care services, medicines, and lost productivity due to death. Governments, healthcare providers and payors are motivated to shift the diagnosis and management of these conditions to earlier stages where better patient outcomes can be delivered at lower costs.

We believe that there is currently no low-cost, front-line, medical device that is effective at screening for heart disease. As a result, frontline physicians face a significant challenge in determining if a patient has heart disease. The conventional ECG is thought of by many to be the front-line tool in cardiac testing, but it has poor sensitivity in detecting CAD or structural heart disease.

Overuse of Expensive Cardiology-Based Diagnostic Testing

We believe that the absence of cost-effective front-line or primary-care-based testing has resulted in the over-use of costly cardiology-based diagnostic tests. Noninvasive cardiac tests are significant contributors to healthcare

costs, accounting for greater than 40% of Medicare Part B spending on medical imaging, or over $17 billion annually according to the U.S. Centers for Medicare & Medicaid Services (“CMS”). There are a variety of effective, though expensive, diagnostic tests used for patients to detect heart disease. These diagnostic tests are typically performed in a specialist cardiology or hospital setting and may include:

Stress ECG testing, a non-invasive diagnostic test with a cost of approximately $200 with, according to the American College of Cardiology, a sensitivity of 68% in the detection of CAD;

Echocardiogram, or echo, a non-invasive diagnostic imaging test, similar to an ultrasound, which is effective in the detection of heart disease; however, the Medicare cost of an echo in a hospital is approximately $600 and can be as much as $3,000 if performed privately;

Cardiac imaging tests, such as nuclear stress tests and coronary computerized tomography angiograms alternatively can be conducted noninvasively, but typically cost $1,000 or more; or

Coronary angiogram, an invasive test in which dye that is visible by X-ray is injected into the blood vessels of the heart. A coronary angiogram can cost in excess of $5,000.

Diastolic Dysfunction, an Early Indicator of Heart Disease

The symptoms and causes of cardiac dysfunction have been researched for many years. The causes of cardiac dysfunction during the contraction (systolic) phase, also called reduced left ventricular ejection fraction, have been well understood for many years. However, according to the American Heart Association Statistics Committee report in 2013, approximately 50% of patients with heart failure (“HF”) symptoms have ejection fraction measures that are not markedly abnormal. In addition, multiple articles published by the National Institutes of Health (“NIH”), state that approximately 50% of HF cases are due to severe diastolic dysfunction, also called heart failure with preserved ejection fraction. HF with preserved ejection fraction (“HFpEF”) is a clinical syndrome in which patients have symptoms and signs of HF with normal or near-normal left ventricular ejection fraction (“LVEF”) (LVEF ≥50%). Roughly half of all patients with HF worldwide have an LVEF ≥50% and nearly half have an LVEF <50%. Thanks to the increased scientific attention about the condition and improved characterization and diagnostic tools, the incidence of HF with reduced ejection fraction (“HFrEF”) dropped while that of HFpEF has increased by 45%. As a result, understanding the causes and progression of diastolic dysfunction has become a key area of scientific and clinical interest. This research has led to the understanding that almost all patients with systolic dysfunction also have diastolic dysfunction and almost all types of heart disease including CAD, valvular disease, cardiomyopathy, hypertension, congenital heart disease, and pericardial disease induce diastolic dysfunction.

According to an article by Dr. Dalane W. Kitzman, MD and Dr. William C. Little, MD published in the February 14, 2012 issue of the Journal of the American Heart Association, diastolic performance is sensitive to nearly all of the common disease processes that affect cardiovascular function. The article indicates that left ventricular, or LV, diastolic function is impaired by all of the common disease processes that affect LV function or produce LV hypertrophy or fibrosis, including hypertension, diabetes, ischemia, myocarditis, toxins and infiltrative cardiomyopathies. LV diastolic dysfunction (“LVDD”) begins early in the heart disease process and continues to increase in severity as heart disease progresses. LVDD is now recognized as one of the earliest signs of heart disease and typical onset occurs when a patient is still asymptomatic. We believe that the early detection of diastolic dysfunction can be a clinically valuable marker for almost all forms of heart disease and age-related cardiac abnormalities that may otherwise be missed by current conventional ECG devices.

MyoVista Insights Cloud Platform and Related AI-ECG Algorithms

We are currently developing a cloud-based ECG management system that is being designed to provide efficient review, reporting, and storage of recorded ECGs. The cloud application is also designed to be able to host multiple AI-ECG algorithms allowing hospital and clinics to gain easy access to innovative AI-ECG algorithms as they become available. The platform is designed to be ECG device agnostic to allow clinical institutions to access AI-ECG algorithms without the need to replace existing ECG devices. Our objective for the MyoVista Insights Cloud Platform is to develop an AI-ECG marketplace to include integration and hosting of AI-ECG algorithms developed and FDA cleared by third parties as well as store and display results from ECG devices. This would be expected to provide

clinical and commercial benefit by increasing the number of available algorithms and clinical use indications, increase our speed of roll-out, and reduce the burden and cost of algorithm R&D on the Company.

We plan to deliver the MyoVista Insights Cloud Platform on a phased basis. Phase 1 has been completed to provide an initial functional platform as a basis for FDA submission and clearance contemporaneous with our first cloud-based AI-ECG algorithm. The Phase 1 platform is designed to receive an acquired ECG signal and then process and report/provide the results of an AI-ECG algorithm as well as provide centralized storage and review of all ECGs. The Company has signed two initial customers as early adopters of the MyoVista Insights cloud application. This will enable the Company to integrate the application directly into clinical workflow environments at the two facilities as well as test features and functionality of the application in clinical operational environments. Initial early adopter customers will not have access to AI-ECG algorithms until they have received regulatory clearance, however they will be able to use the application as a central hub providing a central ECG repository allowing for physician efficient ECG review and storage.

We expect our first AI-ECG cloud-based algorithm to be a low ejection fraction (LVEF ≤ 40) algorithm licensed from Mount Sinai. There is a well-defined predicate for this algorithm which provides greater clarity for the regulatory pathway which we expect to be 510(k), accordingly, we expect this process will be relatively straightforward, assuming appropriate clinical performance of the algorithm. This algorithm was developed using over 100,000 patient records and published clinical data demonstrated strong performance comparable to the predicate. We are in the process of undertaking further work to assess and, if necessary, adjust the algorithm, and prepare for an FDA validation study and submission. We expect the validation study will be performed using retrospective data, i.e. validation using pre-existing ECG’s rather than requiring active patient recruitment, which would reduce costs and timescales compared to prospective clinical validation.

To date we have not yet entered into a discussion with the FDA regarding the MyoVista Insights Cloud Platform or Mount Sinai licensed AI-ECG algorithms but expect to begin that process in the current calendar year. We expect these products to fall under the 510(k) pathway and are aiming for an FDA submission of our MyoVista Insights Cloud Platform and low ejection fraction algorithm in the first half of calendar year 2026.

The Company will focus on signing agreements with multiple early adopter customers. Once the early adopter phase of the MyoVista Insights Cloud Platform is completed it is expected it would expand user functionality and connectivity as well as integration with multiple electronic medical record systems, ECG management systems and direct to ECG device integration.

Following regulatory clearance of the first AI-ECG on the platform we then expect to bring forward a pipeline of other AI-ECG algorithms. We have already licensed a number of AI-ECG algorithms from Mount Sinai and have relationships with other clinical institutions which would enable us to develop further algorithms. The MyoVista Insights Cloud Platform has been designed to be able to host multiple AI-ECG algorithms including third-party algorithms.

MyoVista wavECG Product and Technology

The HeartSciences developed cardiac dysfunction algorithm is being incorporated into the MyoVista wavECG device. It has been developed in response to the relatively recent understanding in cardiology that most forms of heart disease are associated with LV relaxation abnormalities and diastolic dysfunction. The MyoVista wavECG is a 12-lead resting ECG device featuring our proprietary AI-ECG algorithm designed to detect cardiac dysfunction in the diastolic phase, specifically, slower than normal left ventricular relaxation rates.

The MyoVista wavECG also includes the capabilities of a full-featured conventional 12-lead resting ECG including analysis using the Glasgow Algorithm, also known as the Glasgow ECG Interpretation Algorithm. Developed by the University of Glasgow in the United Kingdom, the 12-lead ECG Analysis Algorithm has been relied upon for more than 35 years and is a widely used resting ECG interpretive algorithm. The Glasgow Algorithm has been improved over the years and is licensed to us pursuant to a licensing agreement with The University Court of the University of Glasgow. Under this licensing agreement, we obtained a non-exclusive, worldwide license with automatic renewal provisions and the right to license: (i) software modules for an Android-based platform for the analysis of resting 12-lead electrocardiograms and (ii) all intellectual property rights (including patents, copyright,

trademarks, trade secrets and know-how) relating to the software modules to be used in the MyoVista wavECG (the “Glasgow Licensing Agreement”).

The MyoVista wavECG combines both, the conventional ECG capabilities (including the Glasgow Algorithm) and our proprietary AI-ECG algorithm, designed to detect impaired left ventricular cardiac relaxation abnormalities, as a single test with results presented separately. The MyoVista wavECG has a high-resolution touchscreen display and incorporates many intuitive features commonly associated with a tablet device. In the future we would expect to incorporate further AI-ECG algorithms in the MyoVista wavECG.

Market Opportunity

Diagnostic Gap

We believe that the most significant diagnostic gap in heart disease is early identification. Heart disease often remains asymptomatic for many years until it reaches an acute stage, at which point many patients have a heart attack or die without prior diagnosis of disease. For this reason, heart disease is often referred to as the “silent killer.” In 2012, the United States Preventative Services Task Force stated that there is no good evidence that an ECG helps physicians predict heart risks in people with no symptoms any better than traditional considerations such as smoking, blood pressure and cholesterol levels, acknowledging the diagnostic gap that currently exists.

According to the CDC, cardiovascular disease remains the largest cost for the U.S. healthcare system at approximately $219 billion per year. The cost of treating acute cardiac events and heart failure is especially high in comparison to preventative treatment. Governments, healthcare providers and third-party payors are focused on shifting the diagnosis and management of heart disease to earlier stages where better patient outcomes can be delivered at lower cost; however, to make substantial progress the existing diagnostic gap needs to be closed.

We believe that the scale of cardiac disease as well as changing demographics, growing ECG market, impetus to identify risks earlier through low-cost testing, along with the increasing number and type of health care settings creates a significant opportunity for a device such as the MyoVista wavECG.

Changing Demographics

Heart disease is most commonly found in individuals age 65 and older with incidences of heart disease increasing at 65 years for men and 71.8 years for women. According to the Organization for Economic Co-operation and Development, advances in the field of medicine have led to an increase in life expectancy which, as of

2020, was estimated to average 77.3. years for a person in the U.S., up from 75.4 years in 1990. As life expectancy increases, the average age of the population is expected to increase. According to the U.S. Health and Human Services — Office of the Inspector General (the “HHS”), the population age 65 and older increased from 38.8 million in 2008 to 52.4 million in 2018 (a 35% increase) and is projected to reach 94.7 million by 2060. By 2030, more than 20 percent of U.S. residents are projected to be age 65 and over. Since heart disease is most commonly found in individuals age 65 years and older, and that population pool is increasing, we believe there is a significant opportunity for a device such as the MyoVista wavECG as well as the MyoVista Insights Cloud Platform.

Growing ECG Market

The demand for ECG devices and related supplies known as electrodes is on the rise worldwide. Despite the limitations of the conventional ECG and healthcare guidance around the world that recommends against its use for screening, in the absence of a better alternative, the ECG remains a ubiquitous and widely used test throughout healthcare including non-cardiology settings. It is estimated that 1.5 million to 3.0 million ECGs are performed worldwide every day, making it one of the most commonly used cardiovascular diagnostic tests in healthcare and a fundamental tool in clinical practice. It is estimated that more than 100 million ECGs are performed each year in the United States. The 2019 National Ambulatory Medical Care Survey indicated that office-based patient care physicians, excluding anesthesiologists, radiologists and pathologists, ordered or provided 47 million ECG tests during office visits, and the 2020 National Hospital Ambulatory Medical Care Survey showed that during ambulatory care visits to hospital emergency departments, an additional 32 million ECG tests were ordered or performed by hospital emergency departments.

With the advent of advanced technology, ECG testing market research reports demonstrate that market growth in ECG devices and use is increasing. Precedence Research, a Canada/India based market research company recently released market research on the global ECG market for 2024, the market size is expected grow significantly from $10.93 billion in 2023 to $30.87 billion by 2034.

Impetus to Identify Risks Earlier for More Effective Low-Cost Testing

A key goal of the HHS is reducing healthcare costs. This places pressure on physicians and healthcare institutions to contain healthcare costs. Additionally, one of the key objectives of HHS’s Healthy People 2030, is to increase preventive care for people of all ages. We believe that efforts towards preventive care and maintenance will lead to more testing for high-risk individuals and patients who have existing cardiac conditions. This trend, we believe, in tandem with the push to shorten hospital stays, has created an impetus to identify pre-symptomatic patients at risk more effectively at the front-line physician or clinic level and to treat recovering cardiac patients through outpatient care and rehabilitation.

It is our belief that the MyoVista wavECG device and MyoVista Insights Cloud Platform incorporating AI-ECG algorithms, would be well positioned to respond to the global need for more effective, low-cost ECG testing to facilitate improved referral processes or heart disease.

Changing Nature of Healthcare Providers

The delivery of healthcare in the U.S. is evolving. Alternative treatment sites, such as retail clinics, concierge medicine, urgent care clinics and ambulatory surgical centers, deliver care from qualified providers in settings outside of emergency departments, hospitals or traditional physician offices. We expect this trend to accelerate the drive to provide more effective preventative care and represents a significant opportunity for the introduction of our AI-ECG algorithms that offer an enhanced ability to screen for heart disease.

Capitation Provides an Incentive to Identify Medicare Advantage Patients

Healthcare providers are paid either through fee-for-service or capitation. Fee-for-service is a payment model where services are unbundled and paid for separately. In health care, the fee-for-service payment model incentivizes physicians to provide more treatments because payment is dependent on the quantity, rather than quality, of care. Capitation is a payment arrangement that pays a physician or group of physicians a set amount for each enrolled person assigned to them, per period of time, whether or not that person seeks care. Under capitation, the amount of remuneration is based on the average expected healthcare utilization of that patient, with greater payment for patients with a significant history of medical problems.

Approximately 48% (approximately 28 million people) of those covered by Medicare according to CMS are enrolled in a Medicare Advantage plan. With respect to these patients, CMS pays capitation to healthcare providers. CMS uses risk adjustment to adjust capitation payments to health plans, either higher or lower, to account for the differences in the health costs of individuals with ailments such as heart failure, CAD, angina and valvular heart disease. Accordingly, under CMS guidelines, risk factor adjustments per patient will provide payment that is higher for sicker patients who have conditions where diagnosis codes are documented in the medical record as a result of a face-to-face visit. Therefore, there is a financial incentive to identify those Medicare Advantage patients who are sicker, including those who have undiagnosed ailments such as heart disease. We believe that undiagnosed heart disease represents a significant problem, and we believe insurance plans that have a high number of Medicare Advantage patients could be a target market for the MyoVista cloud-based and hardware-based platforms.

Market Strategy

General

Our objective is to provide AI-ECG solutions in any care setting worldwide in a manner that best suits different providers, either via one of the millions of ECG’s currently in clinical use or via our proprietary MyoVista wavECG device in order to significantly improve front-line testing and referral processes for heart disease. Our business model is primarily focused on recurring revenues for each of the MyoVista Insights Cloud Platform and the MyoVista wavECG device.

The initial revenue model for the MyoVista wavECG device involves the capital sale of the device, recurring revenue from the sale of its proprietary supplies (electrodes) for each test. We would expect to charge for recurring software revenues from the use of AI-ECG algorithms delivered via the Cloud Platform or made available on the MyoVista wavECG device. There are estimated to be millions of ECGs in use worldwide and the Cloud Platform is intended to be device-agnostic thereby facilitating the provision of AI-ECG algorithms to physicians from existing devices. In short, we expect to generate recurring supplies or software revenues and do not expect to rely on high initial capital or device pricing in order to encourage adoption of our AI-ECG algorithms.

Territories

Our initial sales focus will primarily be within the U.S. and European markets where we have established relationships. We intend to market our products in the U.S. using a direct sales force following FDA clearance. Outside of the U.S., for markets such as Europe and Latin America, we intend to utilize medical device distributors that have existing healthcare provider relationships and experience selling ECG devices, which will be supported by a small number of local field personnel.

Potential Markets

We believe that there is a large variety of potential markets for AI-ECG algorithms with new diagnostic capabilities that are not currently available for ECG devices. Conventional ECGs are used throughout healthcare in almost every clinical setting including clinics, doctor’s offices, urgent care centers, and hospitals. We believe that, in many of those settings, the additional information provided by AI-ECG algorithms could be extremely valuable.

Our AI-ECG algorithms range of applications and potential uses are vast, and include providing:

Primary care — front-line cardiac testing/referral tool, heart disease screening.

Retail Healthcare — access to ECG testing at retail sites such as CVS and Walgreens.

Emergency Departments — enhanced ECG testing for emergency room patients.

Cardiologists — prescreening cardiology patients.

Hospitals — in-patient testing or testing prior to discharge, particularly cardiac wards.

Surgery — pre-anesthesia testing, pre/post intervention.

Life Insurance testing — ECGs when required in connection with the issuance of life insurance policies.

Specialty Environments — screening for conditions such as cardiomyopathy, cardiac oncology, drug trials, heart failure, and diabetes.

Athlete testing — cardiac screening programs for athletes.

Early Target Markets

Initially, our focus markets in the U.S. will include: cardiology; primary care providers that serve upper to middle income regions including concierge medicine providers; health systems; retail clinics; and insurers with high levels of Medicare Advantage patients. As additional algorithms obtain FDA clearance, HeartSciences will extend its sales efforts to clinics and physicians that will benefit the most from the specific AI-ECG algorithm.

Reimbursement

In addition to targeting the health care settings described above, a key element of our strategy is to ensure each algorithm qualifies for reimbursement from third-party payors such as CMS (Medicare payor). CPT codes are numbers assigned to each task or service provided by a healthcare provider including medical, surgical and diagnostic services. Insurers use the numbers to determine the procedure and the amount to pay a provider. The American Medical Association has already issued a temporary Current Procedural Terminology (CPT) Category III code for novel AI assistive algorithmic ECG risk assessment for cardiac dysfunction. These codes are designed to facilitate the use, adoption, and potential reimbursement of emerging technologies. This provides physicians and clinical institutions the ability to bill for HeartSciences algorithms that detect different types of heart dysfunction such as systolic and diastolic dysfunction. While we cannot be certain that these new codes will ultimately lead to the issuance of permanent CPT Category I codes, or that insurance coverage or payment can be obtained, if successful, this could potentially provide total reimbursement that is larger than reimbursement for conventional ECG devices, which, in turn, could provide MyoVista wavECG device and the MyoVista Insights Cloud Platform delivering AI-ECG algorithms with a competitive advantage as compared to conventional ECG testing and devices. The MyoVista wavECG device also includes conventional ECG testing capabilities and is expected to also qualify for Medicare reimbursement for existing ECG testing procedures with interpretation and report ranges from approximately $17 to $55 depending on the type of healthcare facility. These charges would go directly to the healthcare facility/physician.

Competition

The medical device industry is characterized by rapidly advancing technologies, intense competition, and a strong emphasis on proprietary products. There are many medical device companies, biotechnology companies, public and private universities and research organizations actively engaged in the R&D of products that may be similar to HeartSciences AI-ECG algorithms and MyoVista hardware. Competitors could include traditional ECG manufacturers such as GE Healthcare Technologies, Inc., (“GE Healthcare”), Koninklijke Philips N.V. (“Philips”), Baxter International, Inc. (“Baxter”), and Nihon Kohden Corporation that may seek to innovate, and new commercial entrants to the AI-ECG market, such as Anumana, Inc. or companies involved in AI healthcare, such as Tempus Labs, Inc. or VIZ.ai that also see the opportunity to bring innovation in a market that, we believe, has significant need for improved products and technology change.

Intellectual Property

Our technology is protected by a patent portfolio as well as trade secrets, which together comprise an important part of the intellectual property protection for our existing and licensed proprietary algorithms (especially when developing proprietary algorithms). We believe that the combination of patents and trade secrets creates valuable competitive barriers in favor of HeartSciences.

The USPTO has issued eight utility patents and one design patent to us, and a patent allowance for a utility patent exclusively licensed to us. The patent expiration dates range from March 2031 to August 2040. We also have fourteen international design registrations and eighteen international utility patents granted (with expiration dates ranging from September 2036 to March 2037) in jurisdictions such as China, Japan, South Korea, the United Kingdom, France, Germany, Mexico, the United Arab Emirates, Brazil, and Australia. We currently have two patent allowances in Europe and Canada, and also have additional pending patent applications in various jurisdictions.

In addition, we have entered into two agreements that are material to our rights to the intellectual property utilized in the MyoVista wavECG:

In January 2014, we entered into an invention assignment agreement under which certain specified MyoVista wavECG technology and proprietary and intellectual property rights thereto (including patents, copyright, trademarks, trade secrets and know-how) were transferred and assigned to us by the inventor; and

In December 2015, we entered the Glasgow Licensing Agreement with The University Court of the University of Glasgow under which we obtained a non-exclusive, worldwide license to software modules for an Android platform for analysis of resting 12-lead electrocardiograms and all intellectual property rights (including patents, copyright, trademarks, trade secrets and know-how) relating to the software modules to be used in the MyoVista wavECG.

Research and Development

The Company’s R&D staff designs our hardware, software and internally developed AI-ECG algorithms. Hardware development assistance is provided by outside consulting firms. The Company internally develops the software for the device along with the assistance of multiple software development contractors. The data science work necessary to build the AI-ECG algorithms is performed both internally and externally using outside data science experts.

Incorporation of all software elements into the MyoVista wavECG hardware is performed internally. We currently employ six full-time R&D staff.

We believe, based on our research and other published research, that further algorithms could be developed for a range of additional clinical indications. To accelerate HeartSciences’ route to market with additional algorithms we entered into the License Agreements with Mount Sinai on September 20, 2023. Please see the section, “Agreements with Mount Sinai related to Commercialization of Multiple AI-ECG Cardiovascular ECG Algorithms developed by Mount Sinai” for additional information regarding the License Agreements. Studies involving the use of the MyoVista wavECG along with proof of concept algorithms for alternative clinical indications have already been published in addition to the growing body of third-party published research in this field.

On November 29, 2022, we entered into a multi-year collaboration agreement with Rutgers, The State University of New Jersey, to research and develop additional AI-ECG algorithms.

FDA and Other Government Regulation

General

Our products are subject to regulation by the FDA and various other federal and state agencies, as well as by foreign governmental agencies. These agencies enforce laws and regulations that govern the development, testing, manufacturing, labeling, advertising, marketing and distribution, and market surveillance of our medical device products.

In addition to those indicated below, the only other regulations we encounter are regulations that are common to all businesses, such as employment legislation, implied warranty laws, and environmental, health and safety standards, to the extent applicable. We will also encounter in the future industry-specific government regulations that would govern our device, if and when developed for commercial use. It may become the case that other regulatory approvals will be required for the design and manufacture of our device.

FDA Requirements and Other Regulatory Approval Requirements

Our products are subject to regulation under the Federal Food, Drug, and Cosmetic Act (the “FDCA”) as implemented and enforced by the FDA. The FDA regulates the development, design, non-clinical and clinical research, manufacturing, safety, efficacy, labeling, packaging, storage, installation, servicing, recordkeeping, premarket clearance or approval, import, export, adverse event reporting, advertising, promotion, marketing and

distribution of medical devices to ensure that medical devices distributed domestically are safe and effective for their intended uses and otherwise meet the requirements of the FDCA.

In addition to U.S. regulations, we are subject to a variety of regulations in the European Economic Area (the “EEA”) governing clinical trials and the commercial sales and distribution of our products. Whether or not we have or are required to obtain FDA clearance or approval for a product, we will be required to obtain authorization before commencing clinical trials and to obtain marketing authorization or approval of our products under the comparable regulatory authorities of countries outside of the United States before we can commence clinical trials or launch sales of our products in those countries. The approval process varies from country to country and the time may be longer or shorter than that required for FDA clearance or approval. Medical devices are generally subject to varying levels of regulatory control based on risk level of the device.

A clearance or authorization letter from the FDA authorizes commercial marketing of the device for one or more specific indications of use. After clearance or authorization, the Company will be required to comply with a number of post-clearance requirements, including, but not limited to, Medical Device Reporting and complaint handling, and, if applicable, reporting of corrective actions. Also, quality control and manufacturing procedures must continue to conform to the QSR. The FDA periodically inspects manufacturing facilities to assess compliance with QSRs, which impose extensive procedural, substantive, and record keeping requirements on medical device manufacturers. In addition, changes to the manufacturing process are strictly regulated, and, depending on the change, validation activities may need to be performed. Accordingly, manufacturers must continue to expend time, money and effort in the area of production and quality control to maintain compliance with the QSR and other types of regulatory controls.

The FDA and the Federal Trade Commission, or FTC, will also regulate the advertising claims of the Company’s products to ensure that the claims it makes are consistent with its regulatory clearances, that there is scientific data to substantiate the claims and that product advertising is neither false nor misleading.

FDA Clearance Process and FDA Validation Clinical Study

Unless an exemption applies, each medical device commercially distributed in the United States requires FDA clearance of a 510(k) premarket notification, granting of a de novo request, or approval of an application for premarket approval, or PMA. Under the FDCA, medical devices are classified into one of three classes—Class I, Class II or Class III—depending on the degree of risk associated with each medical device and the extent of regulatory controls needed to ensure its safety and effectiveness.

Class I includes devices with the lowest risk to the patient and are those for which safety and effectiveness can be assured by adherence to the FDA’s General Controls for medical devices, which include compliance with the applicable portions of the Quality System Regulation, or QSR, facility registration and product listing, reporting of adverse medical events, and truthful and non-misleading labeling, advertising and promotional materials.

Class II devices are subject to the FDA’s General Controls, and special controls as deemed necessary by the FDA to ensure the safety and effectiveness of the device. These special controls can include performance standards, post-market surveillance, patient registries and FDA guidance documents. While most Class I devices are exempt from the 510(k) premarket notification requirement, manufacturers of most Class II devices are required to submit to the FDA a premarket notification under Section 510(k) of the FDCA requesting permission to commercially distribute the device. The FDA’s permission to commercially distribute a device subject to class II controls is generally described as 510(k) clearance.

Devices deemed by the FDA to pose the greatest risks, such as life sustaining, life supporting or some implantable devices, or devices that have a new intended use, or use advanced technology that is not substantially equivalent to that of a legally marketed device, are placed in Class III, requiring approval of a PMA. Some pre-amendment devices are unclassified but are subject to FDA’s premarket notification and clearance process in order to be commercially distributed.

510(k) Clearance Marketing Pathway

To obtain 510(k) clearance, we must submit to the FDA a premarket notification submission demonstrating that the proposed device is “substantially equivalent” to a predicate device already on the market. A predicate device is a

legally marketed device that is not subject to PMA, i.e., a device that was legally marketed prior to May 28, 1976 (pre-amendments device) and for which a PMA is not required, a device that has been reclassified from Class III to Class II or I, or a device that was found substantially equivalent through the 510(k) process. The FDA’s 510(k) clearance process usually takes from three to twelve months, but often takes longer. The FDA may require additional information, including clinical data, to make a determination regarding substantial equivalence. In addition, the FDA collects user fees for certain medical device submissions and annual fees for medical device establishments.

If the FDA agrees that the device is substantially equivalent to a predicate device currently on the market, it will grant 510(k) clearance to commercially market the device. If the FDA determines that the device is “not substantially equivalent” to a previously cleared device, the device is automatically designated as a Class III device. The device sponsor must then fulfill more rigorous PMA requirements or can request a risk-based classification determination for the device in accordance with the “De Novo” process, which is a route to market novel medical devices that are low to moderate risk and are not substantially equivalent to a predicate device.

After a device receives 510(k) clearance, any modification that could significantly affect its safety or effectiveness, or that would constitute a major change in its intended use, will require a new 510(k) or possibly a PMA. The FDA requires each manufacturer to make this determination initially, but the FDA can review any such decision and can disagree with a manufacturer’s determination. If the FDA disagrees with our determination not to seek a new 510(k) clearance, the FDA may retroactively require us to seek 510(k) clearance or possibly a PMA. The FDA could also require us to cease marketing and distribution and/or recall the modified device until 510(k) clearance or a PMA is obtained. Also, in these circumstances, we may be subject to significant regulatory fines and penalties.

PMA Approval Pathway

Class III devices require approval of a PMA before they can be marketed, although some pre-amendment Class III devices for which the FDA has not yet required a PMA are cleared through the 510(k) process. The PMA process is more demanding than the 510(k) premarket notification process. In a PMA application, the manufacturer must demonstrate that the device is safe and effective, and the PMA application must be supported by extensive data, including data from preclinical studies and human clinical trials. The PMA application must also contain a full description of the device and its components, a full description of the methods, facilities, and controls used for manufacturing, and proposed labeling. Following receipt of a PMA application, the FDA determines whether the application is sufficiently complete to permit a substantive review. If the FDA accepts the application for review, it has 180 days under the FDCA to complete its review of a PMA application, although in practice, the FDA’s review often takes significantly longer, and can take up to several years. An advisory panel of experts from outside the FDA may be convened to review and evaluate the application and provide recommendations to the FDA as to the approvability of the device. The FDA may or may not accept the panel’s recommendation. In addition, the FDA will generally conduct a pre-approval inspection of the applicant or its third-party manufacturers’ or suppliers’ manufacturing facility or facilities to ensure compliance with the QSR. PMA devices are also subject to the payment of user fees.

The FDA will approve the new device for commercial distribution if it determines that the data and information in the PMA application constitute valid scientific evidence and that there is reasonable assurance that the device is safe and effective for its intended use(s). A PMA may include post-approval conditions intended to ensure the safety and effectiveness of the device, including, among other things, restrictions on labeling, promotion, sale and distribution, and collection of long-term follow-up data from patients in the clinical study that supported the PMA or requirements to conduct additional clinical studies post-approval. The FDA may condition PMA approval on some form of post-market surveillance when deemed necessary to protect the public health or to provide additional safety and efficacy data for the device in a larger population or for a longer period of use. In such cases, the manufacturer might be required to follow certain patient groups for a number of years and to make periodic reports to the FDA on the clinical status of those patients. Failure to comply with the conditions of approval can result in material adverse enforcement action, including withdrawal of the approval.

Certain changes to an approved device, such as changes in manufacturing facilities, methods, or quality control procedures, or changes in the design performance specifications, which affect the safety or effectiveness of the device, require submission of a PMA supplement. PMA supplements often require submission of the same type of information as a PMA, except that the supplement is limited to information needed to support any changes from the device covered

by the original PMA and may not require as extensive clinical data or the convening of an advisory panel. Certain other changes to an approved device require the submission of a new PMA, such as when the design change causes a different intended use, mode of operation, and technical basis of operation, or when the design change is so significant that a new generation of the device will be developed, and the data that were submitted with the original PMA are not applicable for the change in demonstrating a reasonable assurance of safety and effectiveness. None of our currently developed products require a PMA to be marketed.

De Novo Classification

Medical device types that the FDA has not previously classified as Class I, II or III are automatically classified into Class III regardless of the level of risk they pose. The Food and Drug Administration Modernization Act of 1997 established a new route to market for low to moderate risk medical devices that are automatically placed into Class III due to the absence of a predicate device, called the “Request for Evaluation of Automatic Class III Designation,” or the De Novo classification procedure.

This procedure allows a manufacturer whose novel device is automatically classified into Class III to request down-classification of its medical device into Class I or Class II on the basis that the device presents low or moderate risk, rather than requiring the submission and approval of a PMA application. Prior to the enactment of the Food and Drug Administration Safety and Innovation Act of 2012, or FDASIA, a medical device could only be eligible for De Novo classification if the manufacturer first submitted a 510(k) pre-market notification and received a determination from the FDA that the device was not substantially equivalent. FDASIA streamlined the De Novo classification pathway by permitting manufacturers to request De Novo classification directly without first submitting a 510(k) pre-market notification to the FDA and receiving a not substantially equivalent determination. Under FDASIA, the FDA is required to classify the device within 120 days following receipt of the De Novo application. If the manufacturer seeks reclassification into Class II, the manufacturer must include a draft proposal for special controls that are necessary to provide a reasonable assurance of the safety and effectiveness of the medical device. In addition, the FDA may reject the reclassification petition if it identifies a legally marketed predicate device that would be appropriate for a 510(k) or determines that the device is not low to moderate risk or that general controls would be inadequate to control the risks and special controls cannot be developed.

After initial authorization, any modification that could significantly affect its safety or effectiveness, or that would constitute a major change or modification in its intended use, will require a new 510(k) clearance or, depending on the modification, another De Novo classification request, or PMA approval. The FDA requires each manufacturer to determine whether the proposed change requires submission of a 510(k) or a PMA in the first instance, but the FDA can review any such decision and disagree with a manufacturer’s determination. If the FDA disagrees with a manufacturer’s determination, the FDA can require the manufacturer to cease marketing and/or request the recall of the modified device until 510(k) marketing clearance or PMA approval is obtained. Also, in these circumstances, the manufacturer may be subject to significant regulatory fines or penalties.

The MyoVista wavECG device along with its proprietary software and hardware is classified as a Class II medical device by the FDA. We previously submitted and intended to seek authorization to market the device through submission under the De Novo pathway, however in December 2023 the FDA confirmed that we could submit the MyoVista wavECG device for clearance under the 510(k) pathway following the grant by the FDA in August 2023 of an industry-first De Novo clearance which created a new Class II product code for cardiovascular machine learning-based notification software. We have been preparing for a 510(k) FDA submission in calendar 2025. However, in July 2025, the American Society of Echocardiography released updated guidelines for evaluating LVDD, placing increased emphasis on the echocardiographic measure for impaired cardiac relaxation (e’) and now requiring age-based threshold adjustments. The device’s embedded impaired cardiac relaxation algorithm already incorporates age-adjusted measures, previously agreed with the FDA. We are now evaluating alignment with the newly published standards prior to submission. To date we have not yet entered into a discussion with the FDA regarding the MyoVista Insights Cloud Platform or Mount Sinai licensed AI-ECG algorithms but are aiming to start that process in the current calendar year. We expect these products to fall under the 510(k) pathway and are aiming for an FDA submission of our MyoVista Insights Cloud Platform and low ejection fraction algorithm during the first half of calendar 2026. Delays in receipt or failure to receive the necessary clearances, or the failure to comply with existing or future regulatory requirements, could reduce our business prospects.

Clinical Trials

Clinical trials are almost always required to support a De Novo request and are sometimes required to support a 510(k) submission. All clinical investigations of investigational devices to determine safety and effectiveness must be conducted in accordance with the FDA’s investigational device exemption, or IDE, regulations which govern investigational device labeling, prohibit promotion of the investigational device, and specify an array of recordkeeping, reporting and monitoring responsibilities of study sponsors and study investigators. If the device presents a “significant risk” to human health, as defined by the FDA, the FDA requires the device sponsor to submit an IDE application to the FDA, which must become effective prior to commencing human clinical trials. A significant risk device is one that presents a potential for serious risk to the health, safety or welfare of a patient and either is implanted, used in supporting or sustaining human life, substantially important in diagnosing, curing, mitigating or treating disease or otherwise preventing impairment of human health, or otherwise presents a potential for serious risk to a subject. An IDE application must be supported by appropriate data, such as animal and laboratory test results, showing that it is safe to test the device in humans and that the testing protocol is scientifically sound. The IDE will automatically become effective 30 days after receipt by the FDA unless the FDA notifies us that the investigation may not begin. If the FDA determines that there are deficiencies or other concerns with an IDE for which it requires modification, the FDA may permit a clinical trial to proceed under a conditional approval.

In addition, the study must be approved by, and conducted under the oversight of, an Institutional Review Board, or IRB, for each clinical site. The IRB is responsible for the initial and continuing review of the IDE, and may pose additional requirements for the conduct of the study. If an IDE application is approved by the FDA and one or more IRBs, human clinical trials may begin at a specific number of investigational sites with a specific number of patients, as approved by the FDA. If the device presents a non-significant risk to the patient, a sponsor may begin the clinical trial after obtaining approval for the trial by one or more IRBs without separate approval from the FDA, but must still follow abbreviated IDE requirements, such as monitoring the investigation, ensuring that the investigators obtain informed consent, and labeling and record-keeping requirements. Acceptance of an IDE application for review does not guarantee that the FDA will allow the IDE to become effective and, if it does become effective, the FDA may or may not determine that the data derived from the trials support the safety and effectiveness of the device or warrant the continuation of clinical trials. An IDE supplement must be submitted to, and approved by, the FDA before a sponsor or investigator may make a change to the investigational plan that may affect its scientific soundness, study plan or the rights, safety or welfare of human subjects.

During a study, the sponsor is required to comply with the applicable FDA requirements, including, for example, trial monitoring, selecting clinical investigators and providing them with the investigational plan, ensuring IRB review, adverse event reporting, record keeping and prohibitions on the promotion of investigational devices or on making safety or effectiveness claims for them. The clinical investigators in the clinical study are also subject to FDA regulations and must obtain patient informed consent, rigorously follow the investigational plan and study protocol, control the disposition of the investigational device, and comply with all reporting and recordkeeping requirements. Additionally, after a trial begins, we, the FDA or the IRB could suspend or terminate a clinical trial at any time for various reasons, including a belief that the risks to study subjects outweigh the anticipated benefits.

Post-market Regulation

After a device is cleared or approved for marketing, numerous and pervasive regulatory requirements continue to apply. These include:

establishment registration and device listing with the FDA;

QSR requirements, which require manufacturers, including third-party manufacturers, to follow stringent design, testing, control, documentation and other quality assurance procedures during all aspects of the design and manufacturing process;

labeling and marketing regulations, which require that promotion is truthful, not misleading, fairly balanced and provide adequate directions for use and that all claims are substantiated, and also prohibit the promotion of products for unapproved or “off-label” uses and impose other restrictions on labeling; FDA guidance on off-label dissemination of information and responding to unsolicited requests for information;

clearance or approval of product modifications to 510(k)-cleared devices, or those re-classified to 510(k) cleared devices, that could significantly affect safety or effectiveness or that would constitute a major change in intended use of one of our cleared devices, or approval of a supplement for certain modifications to PMA devices;

medical device reporting regulations, which require that a manufacturer report to the FDA if a device it markets may have caused or contributed to a death or serious injury, or has malfunctioned and the device or a similar device that it markets would be likely to cause or contribute to a death or serious injury, if the malfunction were to recur;

correction, removal and recall reporting regulations, which require that manufacturers report to the FDA field corrections and product recalls or removals if undertaken to reduce a risk to health posed by the device or to remedy a violation of the FDCA that may present a risk to health;

complying with the new federal law and regulations requiring Unique Device Identifiers (UDI) on devices and also requiring the submission of certain information about each device to the FDA’s Global Unique Device Identification Database (GUDID);

the FDA’s recall authority, whereby the agency can order device manufacturers to recall from the market a product that is in violation of governing laws and regulations; and

post-market surveillance activities and regulations, which apply when deemed by the FDA to be necessary to protect the public health or to provide additional safety and effectiveness data for the device.

The manufacturing processes for medical devices are required to comply with the applicable portions of the QSR, which cover the methods and the facilities and controls for the design, manufacture, testing, production, processes, controls, quality assurance, labeling, packaging, distribution, installation and servicing of finished devices intended for human use. The QSR also requires, among other things, maintenance of a device master file, device history file, and complaint files. These requirements impose certain procedural and documentation requirements upon us and our third-party manufacturers related to the methods used in and the facilities and controls used for designing, manufacturing, packaging, labeling, storing, medical devices. As a manufacturer, we will be subject to periodic scheduled or unscheduled inspections by the FDA. Following these inspections, the FDA may assert noncompliance with QSR requirements on a Form 483, which is a report of observations from an inspection, or by way of “untitled letters” or “warning letters” that could cause us or any third-party manufacturers to modify certain activities. A Form 483 notice, if issued at the conclusion of an FDA inspection, can list conditions the FDA investigators believe may have violated QSR or other FDA requirements. We cannot be certain that we or our present or any future third-party manufacturers or suppliers will be able to comply with QSR or other FDA regulatory requirements to the agency’s satisfaction. Failure to comply with these obligations may lead to possible legal or regulatory enforcement action by the FDA.

The FDA has broad regulatory compliance and enforcement powers. If the FDA determines that we failed to comply with applicable regulatory requirements, it can take a variety of compliance or enforcement actions, which may result in any of the following sanctions:

warning letters, untitled letters, fines, injunctions, consent decrees and civil penalties;

recalls, withdrawals, or administrative detention or seizure of our device;

operating restrictions or partial suspension or total shutdown of production;

refusing or delaying requests for 510(k) marketing clearance or PMA approvals of new products or modified products;

withdrawing 510(k) clearances or PMA approvals that have already been granted;

refusal to grant export or import approvals for our device; or

criminal prosecution.

Advertising and Promotion

The FDA and other regulatory agencies closely regulate the post-approval marketing and promotion of medical devices, including standards and regulations for direct-to-consumer advertising, communications about unapproved uses, industry-sponsored scientific and educational activities and promotional activities involving the internet. Devices may be marketed only for the approved or cleared indications and in accordance with the provisions of the approved or cleared label.

Foreign Regulation

As we plan to market our device in the EU and other foreign markets, in addition to regulations in the United States, we will be subject to a variety of foreign regulations governing clinical trials and commercial sales and distribution of our device in foreign countries. Whether or not we obtain FDA approval for a product, we must obtain approval of a product by the comparable regulatory authorities of foreign countries before we can commence clinical trials or marketing of the product in those countries. The approval process varies from country to country, and the time may be longer or shorter than that required for FDA approval. The requirements governing the conduct of clinical trials, product licensing, pricing and reimbursement also vary greatly from country to country and such regulatory requirements have been changing and increasing in some countries. We may be unable to maintain regulatory qualifications, clearances, approvals or CE Certificates of Conformity in these countries or to obtain clearances or approvals in other countries. We may incur significant costs in attempting to obtain, renew, or modify foreign regulatory clearances or approvals, qualifications or CE Certificates of Conformity. If we experience difficulties in receiving, maintaining, renewing or modifying necessary qualifications, clearances, approvals or CE Certificates of Conformity to market our products outside the United States, or if we fail to receive, renew, modify or maintain those qualifications, clearances, approvals or CE Certificates of Conformity, we may be unable to market our products or enhancements in certain international markets effectively, or at all.

On April 5, 2017, a new regulation on medical devices was adopted to establish a modernized and more robust European Union legislative framework, with the aim of ensuring better protection of public health and patient safety: Regulation (EU) 2017/745 of the European Parliament and of the Council of 5 April 2017 on medical devices, amending Directive 2001/83/EC, Regulation (EC) No 178/2002 and Regulation (EC) No 1223/2009 and repealing Council Directives 90/385/EEC and 93/42/EEC, which became applicable from May 26, 2021, (the “EU MDR”). The EU MDR repeals and replaces the EU Medical Devices Directive and unlike directives, which must be given effect through transposition into the national domestic laws of the Relevant States, regulations are directly applicable (i.e., without the need for transposition into national laws implementing them) in all Relevant States. The EU MDR is also applicable in the EEA. Regulations (as EU law instruments) must be applied in their entirety across the EU so that legal acts are automatically and uniformly applied to all EU countries as soon as they enter into force to minimize variations that may arise in transposition of EU law into national law. These modifications may have an effect on the way we design and manufacture products and conduct our business in the EU and EEA. For example, as a result of the transition towards the new regime, Notified Bodies have lengthened their review times, and product introductions or modifications could be delayed or cancelled or otherwise rejected, which could adversely affect our ability to grow our business.

The Company previously achieved a CE Mark under the EU Medical Devices Directive (the “MDD”) in February 2017. The Medical Device Directive was established on June 14, 1993 but the MDD regulatory framework, has since been replaced by EU MDR. In order to sell in member countries of the EEA, our devices must now comply with the essential requirements of the EU MDR. Our CE Mark issued under the MDD lapsed in February 2022 and we will need to establish compliance under EU MDR. An updated CE mark certificate under EU MDR, which we have not yet obtained, would entitle the Company to market the MyoVista wavECG in the European Economic Area as well as other countries for which CE Mark represents an appropriate regulatory standard.

Implications of Being an “Emerging Growth Company” and a “Smaller Reporting Company”

We qualify as an “emerging growth company” under the Jumpstart our Business Startups Act of 2012, or the JOBS Act. For so long as we remain an emerging growth company, we may take advantage of relief from certain reporting requirements and other burdens generally applicable to public companies. In particular, as an emerging growth company we:

are not required to obtain an attestation and report from our auditors on our management’s assessment of our internal control over financial reporting pursuant to the Sarbanes-Oxley Act;

are not required to provide a detailed narrative disclosure discussing our compensation principles, objectives and elements and analyzing how those elements fit with our principles and objectives (commonly referred to as “compensation discussion and analysis”);

are not required to obtain a non-binding advisory vote from our shareholders on executive compensation or golden parachute arrangements (commonly referred to as the “say-on-pay,” “say-on-frequency” and “say-on-golden-parachute” votes);

are exempt from certain executive compensation disclosure provisions requiring a pay-for-performance graph and CEO pay ratio disclosure;

may present only two years of audited financial statements and only two years of related Management’s Discussion & Analysis of Financial Condition and Results of Operations (“MD&A”); and

are eligible to claim longer phase-in periods for the adoption of new or revised financial accounting standards under §107 of the JOBS Act.

We intend to take advantage of these reduced reporting requirements and exemptions, including the longer phase-in periods for the adoption of new or revised financial accounting standards under §107 of the JOBS Act. Our election to use the phase-in periods may make it difficult to compare our financial statements to those of non-emerging growth companies and other emerging growth companies that have opted out of the phase-in periods under §107 of the JOBS Act. Please see “Risk Factors—We are an ‘emerging growth company,’ and any decision on our part to comply with certain reduced disclosure requirements applicable to emerging growth companies could make the Common Stock less attractive to investors.”

Under the JOBS Act, we may take advantage of the above-described reduced reporting requirements and exemptions for up to five years after our initial sale of common equity, or June 2027, pursuant to a registration statement declared effective under the Securities Act, or such earlier time that we no longer meet the definition of an emerging growth company. If we lose our “emerging growth company” status, we may face increased regulatory scrutiny and compliance costs. This includes stricter internal control over financial reporting (ICFR) requirements, expanded executive compensation disclosures and the potential adoption of new accounting standards. These changes can lead to higher audit fees, increased documentation and evidence requirements, and more complex audit processes. In addition, the JOBS Act provides that we would cease to be an “emerging growth company” if we have more than $1.235 billion in annual revenue, have more than $700 million in market value of our Common Stock held by non-affiliates (and are not otherwise eligible to be a smaller reporting company), or issue more than $1 billion in principal amount of non-convertible debt over a three-year period. Further, under current SEC rules we will continue to qualify as a “smaller reporting company” for so long as we have a public float (i.e., the market value of common equity held by non-affiliates) of less than $250 million as of the last business day of our most recently completed second fiscal quarter.

Certain of the reduced reporting requirements and exemptions available to us as an “emerging growth company” are also available to us due to the fact that we also qualify as a “smaller reporting company” under the SEC rules. For instance, smaller reporting companies are not required to obtain an auditor attestation and report regarding internal control over financial reporting; are not required to provide a compensation discussion and analysis; are not required to provide a pay-for-performance graph or CEO pay ratio disclosure; and may present only two years of audited financial statements and related MD&A disclosure.

If we are a smaller reporting company at the time we cease to be an emerging growth company, we may continue to rely on exemptions from certain disclosure requirements that are available to smaller reporting companies. We will continue to be a smaller reporting company so long as (i) the market value of our stock held by non-affiliates is less than $250 million as of the last business day of our second fiscal quarter or (ii) our annual revenue was less than $100 million during our most recently completed fiscal year and the market value of our stock held by non-affiliates is less than $700 million as of the last business day of our second fiscal quarter. Specifically, as a smaller reporting company we may choose to present only the two most recent fiscal years of audited financial statements in our Annual Reports on Form 10-K and, similar to emerging growth companies, smaller reporting companies have reduced disclosure obligations regarding executive compensation.
