Company Overview

We are a medical technology company focused on applying innovative AI-based technology to an ECG, also known as an “EKG,” to expand and improve an ECG’s clinical usefulness. Our objective is to make an ECG a far more valuable cardiac screening tool. HeartSciences’ first product candidate for FDA clearance, the MyoVista, is a resting 12-lead ECG that will incorporate HeartSciences’ first AI-based algorithm designed to provide diagnostic information related to cardiac dysfunction as well as conventional ECG information in the same test. We are also developing a cloud-based platform to provide access to a range of AI-based ECG cardiovascular algorithms (an “AI-ECG”) on an ECG hardware agnostic basis (the “Cloud Platform”) and, in the future, we intend to incorporate additional AI-ECG algorithms in the MyoVista. The AI-ECG algorithms are intended to provide diagnostic information which has traditionally required cardiac imaging. We believe, the combination of a device agnostic cloud platform and MyoVista would allow us to offer AI-ECG solutions across a wide range of healthcare settings from large heath systems to frontline or point of care environments such as primary care. The initial revenue model for the MyoVista, which involves the use of the MyoVista hardware, associated software and consumables for each test, is expected to be “razor-razorblade” as the cable connection to the electrodes used with the MyoVista are proprietary to HeartSciences, and new electrodes are used for every test performed. As further algorithms are made commercially available via the MyoVista or the Cloud Platform, we would expect to adopt revenue models based on algorithm usage and/or recurring subscriptions.

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. The License Agreements, of which there are eleven in total, cover rights to thirteen AI-ECG cardiovascular algorithms, two data science methods for use with ECG waveforms and three filed patents.

Neither the MyoVista hardware, the Cloud Platform, nor any of the AI-ECG algorithms, are cleared for marketing by the FDA and our future success is dependent upon receiving FDA clearances. Additional funding may be required as part of achieving FDA clearance and thereafter would be required to support the sales launch of the MyoVista into the U.S., provide working capital and support further research and development (“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

Table of Contents

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 or specific cardiovascular disease types.

The first AI-ECG algorithm to be incorporated into the MyoVista 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 cardiac dysfunction caused by heart disease and/or age-related cardiac dysfunction. The FDA has now agreed to our proposal to adjust the echocardiographic measurement thresholds in respect to ≥60 year old patients to the FDA which reflects recent clinical findings and we believe will further increase the clinical value of this algorithm. We are in the process of updating our algorithm to reflect these updated echo measurement thresholds. The MyoVista has not yet received FDA clearance.

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.

If we receive FDA clearance for our first product candidates, the MyoVista hardware and its associated cardiac dysfunction algorithm, our main target markets would be frontline healthcare environments in the U.S., such as primary care, 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 cardiac dysfunction to a 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 the MyoVista, require FDA premarket review. The MyoVista 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 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. Accordingly, we are now preparing for a 510(k) FDA submission and are aiming for a clearance un the calendar year 2024. If successful, FDA clearance would provide us the ability to market and sell the MyoVista in the U.S. and additional funding would be required to support the sales launch of the MyoVista in the U.S., provide working capital and support further R&D.

Table of Contents

To date we have had no discussions with the FDA regarding the Cloud Platform or Mount Sinai licensed AI-ECG algorithms although we generally expect the 510(k) pathway to be acceptable.

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 697,000 people in the U.S. died from heart disease in 2020: 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 $229 billion in each of 2017 and 2018, 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 Product and Technology

The HeartSciences-developed cardiac dysfunction algorithm 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 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, including echocardiographic measurement threshold adjustments for ≥60 year old patients in accordance with recent clinical findings and the American Society of Echocardiology Guidelines.

The MyoVista 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 (the “Glasgow Licensing Agreement”).

In the MyoVista, the conventional ECG (including the Glasgow Algorithm) and our proprietary AI-ECG algorithm, designed to detect impaired left ventricular cardiac relaxation abnormalities, are combined as a single test with results presented separately. The MyoVista has a high-resolution touchscreen display and incorporates many intuitive features commonly associated with a tablet device.

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 which is better able to detect heart disease at an early stage, along with the increasing number and type of health care settings creates a significant opportunity for a device such as the MyoVista.

Changing Demographics

Heart disease is most commonly found in individuals aged 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 aged

Table of Contents

65 years and older, and that population pool is increasing, we believe there is a significant opportunity for a device such as the MyoVista as well as our AI-ECG algorithms that are designed to assist frontline physicians in the early detection of heart disease.

Growing ECG Market

The demand for electrocardiograph 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 electrocardiograph market for 2023, the market size is expected grow significantly from $10.93 billion in 2023 to $25.56 billion by 2032.

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, a Cloud Platform and 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

Table of Contents

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.

Market Strategy

General

Our objective is to make our AI-ECG algorithms widely available to significantly improve front-line testing and referral processes for heart disease. Our business model for the MyoVista involves the capital sale of the device, recuring revenue from the sale of its proprietary supplies (electrodes) for each test, and for recurring software revenues from the use of AI-ECG algorithms delivered via the Cloud Platform or made available on the MyoVista. 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 the MyoVista and AI-ECG algorithms.

Territories

Our initial sales focus will primarily be within the U.S. 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 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 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, Walmart 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.

Table of Contents

Early Target Markets

Initially, our focus markets 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 and the Cloud Platform delivering AI-ECG algorithms with a competitive advantage as compared to conventional ECG testing and devices. The MyoVista 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 research and development 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. (“Phillips”), 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. 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:

• In January 2014, we entered into an invention assignment agreement under which certain specified MyoVista 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

Table of Contents

• 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.

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 signal processing software elements along with outside assistance. The user interface software of the MyoVista is designed by the Company along with the assistance of outside consultants. The data science work necessary to build the AI-ECG algorithms is performed both internally and externally using outside consultants.

Incorporation of all software elements into the MyoVista 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 multiple 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 these license agreements. Studies involving the use of the MyoVista and proof of concept algorithms for alternative clinical indications have already been published and there is a 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 develop additional AI-ECG ECG algorithms.

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

Table of Contents

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 pursuant to a registration statement declared effective under the Securities Act of 1933, as amended (the “Securities Act”), or such earlier time that we no longer meet the definition of an emerging growth company. In this regard, 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.

Recent Developments

Going Concern

On July 18, 2023, our independent registered public accounting firm issued an opinion on our audited financial statements, included in our Annual Report on Form 10-K for the year ended April 30, 2023, that contained an explanatory paragraph regarding substantial doubt about our ability to continue as a going concern because we have experienced recurring losses, negative cash flows from operations, and limited capital resources. These events and conditions raise substantial doubt about our ability to continue as a going concern.

Compliance with Nasdaq Listing Requirements

On December 21, 2022, we received notice from the Listing Qualifications Staff (“Staff”) of The Nasdaq Stock Market LLC (“Nasdaq”) indicating that we were not in compliance with the minimum stockholders’ equity requirement for continued listing on the Nasdaq Capital Market, under Listing Rule 5550(b)(1) (the “Minimum Stockholders’ Equity Requirement”), because our stockholders’ equity of $1,082,676 as reported in our Quarterly Report on Form 10-Q for the period ended October 31, 2022 was below the required minimum of $2.5 million, and because, as of October 31, 2022, we did not meet the alternative compliance standards, relating to the market value of listed securities of $35 million or net income from continuing operations of $500,000 in the most recently completed fiscal year or in two of the last three most recently completed fiscal years.

On August 2, 2023, we received a letter from the Staff indicating that, based upon the closing bid price of our Common Stock for the last 30 consecutive business days, we no longer met the requirement to maintain a minimum bid price of $1 per share (the “Minimum Bid Price Requirement”). In accordance with Nasdaq listing rules, we have until January 29, 2024 to regain compliance with the Minimum Bid Price Requirement. In the event we do not regain compliance during this period, we may be eligible to seek an additional 180 calendar day compliance period if we meet

Table of Contents

the Nasdaq continued listing requirement for market value of publicly held shares and all other initial listing standards, with the exception of the Minimum Bid Price Requirement, and provide written notice to Nasdaq of our intent to cure the deficiency during this second compliance period.

We attended an August 17, 2023 hearing before the Nasdaq Hearing Panel (the “Panel”) and requested the continued listing of our securities on the Nasdaq Capital Market pending our return to compliance with the Minimum Stockholder’s Equity Requirement and Minimum Bid Price Requirement.

On November 22, 2023, we were formally notified by the Panel that we have demonstrated compliance with the Minimum Stockholders’ Equity Requirement. Pursuant to Nasdaq Listing Rule 5815(d)(4)(B), we will be subject to a Mandatory Panel Monitor through November 22, 2024.

On January 30, 2024, we received a letter from the Panel advising that we have been granted an additional 180-day extension to July 29, 2024, to regain compliance with the Minimum Bid Price Requirement.

Patents

In September 2023, we were issued a notice of patent allowance from the Brazilian Patent and Trademark Office and the United Arab Emirates Ministry of Economy covering MyoVista wavelet technology utilizing AI for early detection of heart disease.

Bridge Warrant Amendment No. 2

On February 3, 2023, we entered into a second amendment to the Bridge Warrants (as defined in the Glossary of Terms), which we refer to as the Bridge Warrant Amendment No. 2. The Bridge Warrant Amendment No. 2 amended the Bridge Warrants (as previously amended) by (i) lowering the exercise price of $4.25 for a period of ten (10) business days beginning February 3, 2023 and ending February 16, 2023 (the “Limited Period”), during which period the exercise price was set at $1.00, subject to adjustments set forth in the Bridge Warrant; (ii) providing that during the Limited Period, the holder was able, in its sole discretion, to elect a cashless exercise of the Bridge Warrant in whole or in part, pursuant to which the holder received a net number of shares of Common Stock equal to one-third of the total number of shares into which the Bridge Warrant could otherwise have been exercised; and (iii) removing the exercise price adjustment provisions of the Bridge Warrants with limited exceptions for transactions such as stock dividends, stock splits, stock combinations and reverse stock splits. Additionally, the Bridge Warrant Amendment No. 2 provided that in the event that the aggregate number of shares of Common Stock to be received by a holder upon an exercise of its Bridge Warrant during the Limited Period would result in such holder’s receiving shares of Common Stock in excess of its applicable Bridge Maximum Percentage (as defined in the Glossary of Terms), in lieu of delivery of shares of Common Stock in excess of the Bridge Maximum Percentage, the holder would receive such excess shares as pre-funded warrants substantially in the form of the Pre-Funded Bridge Warrants (as defined in the Glossary of Terms), with certain exercise price adjustment provisions removed.

Further, the Bridge Warrant Amendment No. 2 included a waiver of Section 4(w) of the Bridge SPA (as defined in the Glossary of Terms), which placed certain restrictions on the Company’s ability to issue securities for a specified period of time.

During the Limited Period, we issued 1,172,304 shares of Common Stock and a pre-funded warrant to purchase 150,000 shares of Common Stock (the “Remaining Pre-Funded Bridge Warrant”) pursuant to exercises of the Bridge Warrants and received approximately $1.3 million in proceeds from these exercises. At the end of the Limited Period, Bridge Warrants to purchase 298,667 shares of Common Stock (the “Remaining Bridge Warrants”) remained outstanding, with an exercise price of $4.25 per share, subject to adjustments as set forth in the Bridge Warrants.

Lincoln Park Purchase Agreement

On March 10, 2023, we entered into the Lincoln Park Purchase Agreement with Lincoln Park pursuant to which we have the right, but not the obligation, to sell to Lincoln Park up to $15,000,000 of our Common Stock the (“Purchase Shares”) from time to time over a 36-month term beginning only after certain conditions set forth in the Lincoln Park Purchase Agreement have been satisfied, including that the registration statement registering the Purchase Shares for resale (the “Lincoln Park Registration Statement”) shall have been declared effective under the Securities Act. In accordance with the Lincoln Park Purchase Agreement, on March 13, 2023, we issued 100,000 shares of our Common Stock (the “Initial Commitment Shares”) to Lincoln Park as consideration for its commitment to purchase the Purchase

Table of Contents

Shares under the Lincoln Park Purchase Agreement. As a result of Lincoln Park’s purchases cumulatively reaching an aggregate amount of $2,000,000 of Purchase Shares, in accordance with the Lincoln Park Purchase Agreement, we will issue an additional 62,500 shares of our Common Stock (the “Additional Commitment Shares”, and, together with the Initial Commitment Shares, the “Commitment Shares”) to Lincoln Park as consideration for such purchases.

On January 17, 2024, we obtained shareholder approval to issue to Lincoln Park, pursuant to the Lincoln Park Purchase Agreement, shares of our Common Stock, including the Commitment Shares, which exceed 1,927,022 shares, which was then equal to 19.99% of the shares of our Common Stock outstanding immediately prior to the execution of the Lincoln Park Purchase Agreement. Pursuant to the Lincoln Park Purchase Agreement, we may not direct Lincoln Park to purchase any shares of our Common Stock if those shares, when aggregated with all other shares of our Common Stock then beneficially owned by Lincoln Park (as calculated pursuant to Section 13(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and Rule 13d-3 thereunder), would result in Lincoln Park and its affiliates beneficially owning more than 9.99% of the then total outstanding shares of Common Stock (the “Beneficial Ownership Limitation”).

Lincoln Park Registration Rights Agreement

Concurrently with entering into the Lincoln Park Purchase Agreement, we entered into a registration rights agreement with Lincoln Park (the “Registration Rights Agreement”) pursuant to which we agreed to register the resale of the Purchase Shares and Commitment Shares that have been and may be issued to Lincoln Park under the Lincoln Park Purchase Agreement pursuant to the Lincoln Park Registration Statement. On March 29, 2023, we filed with the SEC the Lincoln Park Registration Statement registering the resale of the Purchase Shares and Commitment Shares that have been and may be issued to Lincoln Park under the Lincoln Park Purchase Agreement, and the SEC declared the Lincoln Park Registration Statement effective on April 10, 2023.

As of February 28, 2024, we have issued 2,864,522 shares to Lincoln Park, including the Initial Commitment Shares, receiving gross proceeds of approximately $1.2 million.

Senior Unsecured Promissory Drawdown Loan Note

On September 6, 2023, we entered into the MSW Note with Matthews. The MSW Note provided for an unsecured drawdown loan of up to $1,000,000, drawn in installments consisting of (i) $250,000 on or prior to September 8, 2023, (ii) $250,000 on or prior to September 20, 2023, and (iii) further drawdowns of up to $500,000 in such amounts and such times to be mutually agreed upon between us and the Lender.

In consideration of the MSW Note, we agreed to pay a facility fee to the Lender as follows:

• warrants to acquire 500,000 shares of Common Stock, exercisable at $1.00 per share, which shall be issued to the Lender upon the completion of the first drawdown;

• warrants to acquire 500,000 shares of Common Stock, exercisable at $1.25 per share, which shall be issued to the Lender upon the completion of the first drawdown and 250,000 of such Warrants shall be issued to the Lender pro-rata based on further drawdowns up to $500,000; and

Agreements with Mount Sinai related to Commercialization of Multiple AI-ECG Cardiovascular ECG Algorithms developed by Mount Sinai

On September 20, 2023, we entered into the License Agreements for the purpose of acquiring certain rights related to intellectual property developed by Mount Sinai. We will use these rights to focus on commercialization efforts of the licensed cardiovascular AI-ECG ECG algorithms developed by Mount Sinai. Commercialization will include efforts related to pursuing FDA clearance and European regulatory approval as well as ongoing sales efforts once an algorithm achieves regulatory clearance. The License Agreements include a total of eleven (11) license agreements for Mount Sinai-developed intellectual property, a memorandum of understanding between HeartSciences and Mount Sinai for on-going cooperation, collaboration, and data access as well as the Mount Sinai Securities Purchase Agreement required to secure the rights related to the License Agreements.

Intellectual Property Description

Mount Sinai has a clinical database with millions of patients’ ECG records for the use of building AI-ECG electrocardiography (AI-ECG) algorithms. The database includes clinical, as well as diagnostic imaging information related to many types of cardiovascular diseases. This has enabled its researchers to develop a range of AI-ECG ECG algorithms using state-of-the art data science development methods including the use of cutting-edge vision transformers (ViT).

We have entered into the License Agreements which cover certain usage rights to Mount Sinai’s AI-ECG ECG algorithms, technology and patents in the field of screening for, or diagnosis of, certain cardiovascular diseases using electrocardiogram ECG data. The following License Agreements provide for worldwide rights to the ECG algorithms and all but two of the ECG algorithms provide for exclusive rights to the algorithms:

• Deep learning ECG algorithms to derive Left Ventricular Ejection measures and detect Right Ventricular dysfunction;

• Deep Learning ECG algorithm to detect Pulmonary Embolism;

• Deep Learning ECG algorithms to predict right ventricle size and right ventricle systolic function;

• Deep Learning ECG algorithm to Predict Premature Ventricular Contraction (PVC) related cardiomyopathy;

• Deep learning ECG algorithm to identify left heart valvular dysfunction — mitral regurgitation — (nonexclusive);

• Deep learning ECG algorithm to identify left heart valvular dysfunction — aortic stenosis (nonexclusive);

• Electrocardiogram deep learning interpretability toolbox;

• HeartBEiT Vision Transformer development platform;

• Vision Transformer-based ECG algorithm to derive Left Ventricular Ejection Fraction;

• Vision Transformer-based ECG algorithm to detection elevated ST segment; and

• Vision Transformer-based ECG algorithm to detect Hypertrophic Cardiomyopathy.

Mount Sinai Issuances

On November 15, 2023, we closed the transactions contemplated under the Mount Sinai Securities Purchase Agreement and the licenses under the License Agreements, which became effective on that date. On November 16, 2023 and pursuant to the Mount Sinai Securities Purchase Agreement, we issued to Mount Sinai the following:

• 4,854,853 shares of Common Stock (the “Consideration Shares”);

• pre-funded warrants to purchase up to 710,605 shares of Common Stock, with an exercise price per share of $0.00001, which warrants were issued in lieu of shares of Common Stock issuable to Mount Sinai to ensure that the number of shares of Common Stock held by Mount Sinai does not exceed the Beneficial Ownership Limitation (the “MTS Pre-Funded Warrants”); and

Table of Contents

• Common stock warrants to purchase up to 914,148 shares of Common Stock, having an exercise price per share equal to $0.5060, (the “MTS Warrants” and collectively with the Consideration Shares and the MTS Pre-Funded Warrants, the “MTS Securities”).

On December 1, 2023, the Company satisfied all material closing conditions of the Mount Sinai Securities Purchase Agreement and the MTS Warrants thereafter became fully exercisable by Mount Sinai.

Registration rights related to the MTS Securities provide that on or prior to the date of one hundred and fifty days (150) days after the closing date, we shall prepare and file with the SEC a Registration Statement on Form S-1 (or such other form as applicable) covering the resale under the Securities Act of the MTS Securities issued to Mount Sinai, subject to any limitations imposed by the Nasdaq Rules.

Mount Sinai Licensed Algorithms Development Methods

The application of AI to the ECG is playing an increasingly important role in patient screening, diagnosis, and management.

As larger rich clinical data sets become available, more sophisticated AI-ECG algorithms are being developed and delivering improved diagnostic performance. Improved data sciences methods such as convolutional neural networking (“CNNs”) and recently emerged vision transformer (“ViT”) methods allow for developing algorithms to diagnose heart disease conditions that were not possible in the past. Some examples include detection of left ventricle systolic dysfunction, right ventricle dysfunction, hypertrophic cardiomyopathy and valvular heart disease through low-cost ECG testing.

Mount Sinai is one of few nationally recognized cardiology institutions available that has created clinical records data sets greater than five million. They have used these extremely large ECG clinical data sets to develop innovative AI-ECG ECG algorithms using state-of-the art data science methods. The Mount Sinai algorithms were developed using methods such as CNNs as well as state-of-the-art ViT methods. HeartSciences has secured license agreements for 13 of Mount Sinai-developed AI-ECG ECG algorithms. Below are examples of algorithms HeartSciences believes to have important clinical value and significant commercial potential:

• Left Ventricle Ejection Fraction <40%

• Left Ventricle Ejection Fraction >50%

• Right Ventricle Dysfunction

• Pulmonary Embolism

• LV Mitral Valve Regurgitation

• LV Aortic Valve Stenosis

• Hypertrophic Cardiomyopathy

Upon the completion of the offering, HeartSciences intends to conduct an expedited in-depth analysis to determine which of the ECG algorithms provide the best combination of clinical performance along with strong commercialization opportunity. HeartSciences also expects to increase internal data science staff to ensure the ability to respond to any data science needs related to fine tuning some of the existing algorithms if needed for optimal sensitivity/specificity performance.

Regulatory Approval

HeartSciences intends to work quickly to obtain regulatory approval on a number of key algorithms. This will require increased regulatory staff to support expedited regulatory submissions to the FDA for clearance and European regulatory approval. HeartSciences will use recruiting services that are specialized in finding and recruiting qualified candidates. Upon satisfying the Financing Requirement contemplated by the License Agreements, Mount Sinai will become a significant shareholder in the Company. Assuming at least $5,000,000 is raised in this offering, our anticipated commercialization efforts will initially focus on achieving FDA clearance and European CE Mark regulatory approval.

Table of Contents

Algorithm Delivery Platforms

HeartSciences intends to make the algorithms available worldwide on an ECG hardware agnostic basis through the use of Health Insurance Portability and Accountability Act (HIPAA) and European General Data Protection Regulation (GDPR) compliant cybersecure cloud-based environment. Clinical institutions will be able to upload ECGs from anywhere and have the algorithm diagnostic results returned to them electronically. HeartSciences has identified software contractors that have developed ECG cloud environments in the past and are available to assist with design and development of a cloud environment that will meet these requirements. HeartSciences also intends to make multiple of these algorithms available on its MyoVista hardware platform. As the licensed algorithms have been developed with advanced data science methods using extremely large datasets, many of the advanced algorithms will require significant computing power. HeartSciences will need to test each algorithm to determine which one may be made available on the MyoVista hardware platform and may also need to upgrade the hardware platform of the MyoVista to increase hardware performance.

U.S. Commercialization Strategy

Sales staffing requirements due to the additional Mount Sinai algorithms will not initially change as these algorithms require regulatory approvals and approvals will most likely be staggered over time. Sales efficiencies should improve since sales access to existing customers that have already adopted the use of one algorithm is easier and the technical ECG upload processes of using the cloud-based algorithms is the same for all cloud-based algorithms. The algorithms will also be used in many of the same front-line clinical environments. The algorithms will be used in front-line clinical pathways as ECGs are used today but provide improved ECG testing for a more efficient patient referral process by detecting patients earlier that need to have image-based cardiology testing. The improved referral process can reduce healthcare costs while improving patient care by improving early detection of heart disease while reducing patient referrals for testing not needed on patients that could not effectively be tested through older conventional ECG testing.

HeartSciences believes there is a significant opportunity to partner with both pharmaceutical and medical device companies that would benefit from improved ECG testing for heart diseases related to their drug treatments or medical devices, for example partnering with a heart valve replacement provider to accelerate sales efforts by increasing the use of a new ECG algorithm to detect valvular disease. This would lower the cost of initial sales efforts by partially funding HeartSciences sales efforts.

Revenue Model related to Reimbursement and Algorithm Use

Insurers and payors such as CMS (Medicare) use payment codes to determine the procedure and the amount to pay providers (physicians and clinical institutions). The American Medical Association (AMA) has already issued a temporary Current Procedural Terminology (CPT) Category III code for 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 with the ability to bill for multiple licensed algorithms which would allow clinical institutions to bill payors for use of many of the algorithms as they obtain regulatory approval. 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 either are successful this will assist with adoption of the AI-ECG algorithms. As further algorithms are made commercially available via the MyoVista or cloud-based platform we would expect to adopt revenue models based on algorithm usage and/or recurring subscriptions.

Significant Early European Opportunity

HeartSciences sees significant additional commercial opportunities in Europe based on HeartSciences’ ongoing engagement with European based key opinion leaders (KOLs). Due to the pandemic and a chronic lack of funding, many European national health systems are suffering from cardiology diagnostic backlogs that are up to one year for most types of diagnostic imaging. Today there is not an effective low-cost method to prioritize these patient backlogs. This has led to an increase in adverse cardiovascular events for patients suffering these increased waiting periods.

Table of Contents

Below are excerpts from recent articles related to chronic backlog issues in multiple European national health systems.

Telegraph.co.uk August 2023 Titled “It’s not just the NHS: health services are imploding all over Europe”

UK NHS (UK National Health Service) waiting list in the UK stood at 2.3 million in 2009 but by early 2020 had increased to 4.3 million. Today, the figure is about 7 million — equivalent to more than a tenth of the population. Overall, survey company Eurofound reported that more than one in five people in EU countries had foregone medical care, including examinations and treatments, during the first year of the pandemic — with a similar number reporting they still had unmet needs in spring 2022.

“We know that we’ve almost certainly missed a lot of serious illness during the pandemic,” says Anita Charlesworth, director of research at the Health Foundation and a former top civil servant. “And being able to have a timely diagnosis is really important. Early diagnosis tends to be associated with better outcomes and it tends to mean that you need less complex healthcare intervention, which is more costly in the end. “So early detection and diagnosis is in the patient’s interest and it’s also in the taxpayer’s interests.”

WHO March 2023 titled “The health workforce crisis in Europe is no longer a looming threat — it is here and now.”

European Region, …national health systems are struggling to keep up with the rising demand for health care, exacerbated by service backlogs caused by the COVID-19 pandemic, rising expectations from patients and the health risks posed by climate change and emergencies.

New York Times July 16, 2023 “National Treasure, Tarnished: Can Britain Fix Its Health Service?”

Cardiovascular-related fatalities, which can be linked to delays in treatment, were up particularly sharply, according to Stuart McDonald, an expert on mortality data at LCP, a London-based pension and investment advisory firm.

These chronic issues have many national health systems in Europe seeking more effective low-cost methods to assist with prioritizing and reducing the backlog through improved low-cost testing. Due to typically shorter regulatory review periods for European regulatory submissions as compared to FDA review periods HeartSciences feels there will be significant commercial opportunities early-on in Europe.

Debt Conversion

On January 24, 2023, we entered into Amendment No. 4 to the Loan and Security Agreement dated April 24, 2020 (the “Loan and Security Agreement”) with Front Range Ventures LLC (“FRV”) and Adams.

Our business, results of operations, financial condition and prospects could also be harmed by risks and uncertainties that are not presently known to us or that we currently believe are not material. If any such risks actually occur, our business, platform, reputation, brand, results of operations, financial condition and prospects could be materially and adversely affected. In such an event, the market price of our securities could decline, and you could lose all or part of your investment. Please also read carefully the section below titled “Cautionary Note Regarding Forward-Looking Statements.”

Risks Related to this Offering

The sale or issuance of our Common Stock to Lincoln Park may cause dilution and the sale of the shares of Common Stock acquired by Lincoln Park, or the perception that such sales may occur, could cause the price of our Common Stock to fall.

On March 10, 2023, we entered into the Lincoln Park Purchase Agreement with Lincoln Park pursuant to which we have the right, but not the obligation, to sell to Lincoln Park up to $15,000,000 of shares of our Common Stock from time to time over a 36-month term beginning only after certain conditions set forth in the Lincoln Park Purchase Agreement have been satisfied, including that that the registration statement registering such shares for resale shall have been declared effective under the Securities Act. In accordance with the Lincoln Park Purchase Agreement, on March 13, 2023, we issued 100,000 shares of our Common Stock to Lincoln Park (the “Initial Commitment Shares”) as consideration for its commitment to purchase the Lincoln Park Shares under the Lincoln Park Purchase Agreement. As a result of Lincoln Park’s purchases cumulatively reaching an aggregate amount of $2,000,000 of Lincoln Park Shares, in accordance with the Lincoln Park Purchase Agreement, we will issue an additional 62,500 shares of our Common Stock to Lincoln Park as consideration for such purchases.

Under the applicable rules of Nasdaq, on January 17, 2024, we obtained shareholder approval to issue to Lincoln Park, pursuant to the Lincoln Park Purchase Agreement, shares of our Common Stock, including the Commitment Shares, which may exceed 19.99% of the shares of our Common Stock outstanding immediately prior to the execution of the Lincoln Park Purchase Agreement (the “Beneficial Ownership Cap”). Pursuant to the Lincoln Park Purchase Agreement, we may not direct Lincoln Park to purchase any shares of our Common Stock if those shares, when aggregated with all other shares of our Common Stock then beneficially owned by Lincoln Park (as calculated pursuant to Section 13(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and Rule 13d-3 thereunder), would result in Lincoln Park and its affiliates beneficially owning more than 9.99% of the then total outstanding shares of Common Stock (the “Beneficial Ownership Limitation”). As of February 28, 2024, we have issued 2,864,522 shares to Lincoln Park, including the Initial Commitment Shares, receiving gross proceeds of approximately $1.2 million.

We generally have the right to control the timing and amount of any future sales of our shares to Lincoln Park. Additional sales of our Common Stock, if any, to Lincoln Park will depend upon market conditions and other factors to be determined by us. We may ultimately decide to sell to Lincoln Park all, some or none of the shares of our Common Stock that may be available for us to sell pursuant to the Lincoln Park Purchase Agreement. If and when we do sell shares to Lincoln Park, after Lincoln Park has acquired the shares, Lincoln Park may resell all, some or none of those shares at any time or from time to time in its discretion. Therefore, sales of the Lincoln Park Shares to Lincoln Park by us could result in substantial dilution to the interests of other holders of our Common Stock. Additionally, the sale of a substantial number of the Lincoln Park Shares to Lincoln Park, or the anticipation of such sales, could make it more difficult for us to sell equity or equity-related securities in the future at a time and at a price that we might otherwise wish to effect sales.

We may not have access to the full amount available under the Lincoln Park Purchase Agreement.

Under the Lincoln Park Purchase Agreement, we may, at our discretion from time to time over a 36-month period commencing after the satisfaction of certain conditions set forth in the Lincoln Park Purchase Agreement, subject to the Beneficial Ownership Limitation, on any single business day, direct Lincoln Park to purchase shares of our Common Stock in amounts up to 50,000 shares (subject to adjustment), subject to a maximum commitment by Lincoln Park of $750,000 per single regular purchase. Although the Lincoln Park Purchase Agreement provides that

Table of Contents

we may sell up to $15,000,000 of our Common Stock to Lincoln Park, only 21,423,965 shares of our Common Stock are being offered under this prospectus, which represents the shares of our Common Stock which may be issued to Lincoln Park in the future under the Lincoln Park Purchase Agreement, if and when we sell shares of our Common Stock to Lincoln Park under the Lincoln Park Purchase Agreement. As a result, depending on the market prices of our Common Stock, we may not be able to sell the full $15,000,000 commitment amount contemplated by the Lincoln Park Purchase Agreement. For example, assuming that we sell all of the 21,423,965 Lincoln Park Shares being registered for resale under this prospectus at an average purchase price of $0.1164 per share (which was the closing price of our Common Stock on the Nasdaq Capital Market on February 28, 2024), our total gross proceeds would only be approximately $2,493,750. As of February 28, 2024, we have issued 2,864,522 shares to Lincoln Park, including the Initial Commitment Shares, receiving gross proceeds of approximately $1.2 million.

In the event that the market prices of our Common Stock increases, we may be able to issue and sell more than the 21,423,965 shares of our Common Stock to Lincoln Park in an effort to obtain up to the full $15,000,000 commitment amount contemplated by the Lincoln Park Purchase Agreement; provided in such case we will need to register for resale under the Securities Act such incremental additional shares of our Common Stock, which will require additional time, resources and cost to us. In addition, the issuance and sale of such additional shares could cause substantial dilution to our stockholders.

The extent we rely on Lincoln Park as a source of funding will depend on a number of factors including the prevailing market price of our Common Stock and the extent to which we are able to secure working capital from other sources. If obtaining sufficient funding from Lincoln Park were to prove unavailable or prohibitively dilutive, we will need to secure another source of funding in order to satisfy our working capital needs. Even if we sell all $15,000,000 under the Lincoln Park Purchase Agreement to Lincoln Park, we may still need additional capital to fully implement our business, operating and development plans. Should the financing we require to sustain our working capital needs be unavailable or prohibitively expensive when we require it, the consequences could have a material adverse effect on our business, operating results, financial condition and prospects.

Our management will have broad discretion over the use of the net proceeds from our sale of the Lincoln Park Shares to Lincoln Park and any cash exercise of the Warrants. You may not agree with how we use the proceeds and the proceeds may not be invested successfully.

Our management will have broad discretion as to the use of the net proceeds from our sale of the Lincoln Park Shares to Lincoln Park and any cash exercise of the Warrants, and we could use them for purposes other than those contemplated at the time of commencement of this offering. Accordingly, you will be relying on the judgment of our management with regard to the use of those net proceeds, and you will not have the opportunity, as part of your investment decision, to assess whether the proceeds are being used appropriately. It is possible that, pending their use, we may invest those net proceeds in a way that does not yield a favorable, or any, return for us. The failure of our management to use such funds effectively could have a material adverse effect on our business, financial condition, operating results and cash flows.

We will need additional capital beyond the capital raised from the sale of the Lincoln Park Shares to Lincoln Park, and the sale of additional shares of our Common Stock, equity and/or debt securities could result in additional dilution to our shareholders.

Although the net proceeds of the sale of the Lincoln Park Shares to Lincoln Park, if any, are anticipated to be sufficient to achieve FDA clearance, which would allow us to market the MyoVista in the United States, there is no assurance that this would be the case and further funding may be required. We will need to raise additional capital beyond the capital raised in the IPO and from the sale of Lincoln Park Shares to Lincoln Park in order to support the sales launch of the MyoVista into the U.S., provide working capital and support further R&D. Such additional capital may be raised through a combination of private and public equity offerings, debt financings and collaborations, and strategic and licensing arrangements. To the extent that we raise additional capital through the issuance of our Common Stock, equity and/or convertible debt securities, your ownership interest will be diluted, and the terms may include liquidation or other preferences that adversely affect your rights as a holder of our Common Stock. Debt financing, if available, may involve agreements that include covenants limiting or restricting our ability to take certain actions, such as incurring debt, without prior approval, making capital expenditures or declaring dividends. If we raise additional funds through strategic partnerships and alliances and licensing arrangements with third parties, we may have to relinquish valuable rights to our technologies or product or grant licenses on terms that are not favorable to us.

Table of Contents

If we are unable to raise additional funds through equity or debt financing when needed, we may be required to delay, limit, reduce or terminate our product development, sales launch or marketing efforts or grant rights to develop and market product that we would otherwise prefer to develop and market ourselves.

Risks Related to Our Business and Industry

Interruptions in computing and data management cloud systems could impair the delivery of our cardiac monitoring services.

The success of our products and services will be dependent upon our ability to perform computing functions associated with our cardiac signal processing algorithms and data management. The diagnostic and monitoring functions rely on the uninterrupted availability of third-party cloud based computational and data management services. Availability of the cloud-based infrastructure is a critical link in our ability to deliver our services and could have a material adverse effect on our business and operating results. Furthermore, loss of data due to catastrophic events at the sites for these cloud-based computer systems could cause permanent harm to our customers. These adverse events associated with unavailability of our cloud based computational infrastructure could result in liability, claims and litigation against us for damages or injuries resulting from the disruption in service.

Our systems are also expected to be vulnerable to damage or interruption in cloud computational services from earthquakes, floods, fires, power loss, technical failures, terrorist attacks, computer viruses, break-ins, sabotage, and acts of vandalism. Despite any precautions that we may take, the occurrence of a natural disaster or other unanticipated problems could result in lengthy interruptions in these services.

Our proprietary data analytics engine may not operate properly, which could damage our reputation, give rise to claims against us or divert application of our resources from other purposes, any of which could harm our business and operating results.

The ECG data that is gathered through our products is governed AI-based ECG algorithms that are part of our service. The continuous development, maintenance and operation of our deep-learned backend data analytics engine is expensive and complex, and may involve unforeseen difficulties including material performance problems, undetected defects or errors. We may encounter technical obstacles, and it is possible that we may discover additional problems that prevent our proprietary algorithms from operating properly. We may also attempt to develop new capabilities and incorporate new technologies, including artificial intelligence, which could impact our data analytics platform’s performance. If our data analytics platform does not function reliably or fails to meet physician or payor expectations in terms of performance, physicians may stop prescribing our service and payors could attempt to cancel their contracts with us.

Any unforeseen difficulties we encounter in our existing or new software, cloud-based applications, telecommunication service providers, and analytics services, and any failure by us to identify and address them could result in loss of revenue or market share, diversion of development resources, injury to our reputation and increased service and maintenance costs. Correction of defects or errors could prove to be impossible or impracticable. The costs incurred in correcting any defects or errors may be substantial and could adversely affect our operating results.

USE OF PROCEEDS

We will not receive any of the proceeds from the Shares sold by the Selling Stockholders, other than any proceeds from any cash exercise of the Warrants. We will, however, receive proceeds from the sale of the Lincoln Park Shares directly to Lincoln Park pursuant to the Lincoln Park Purchase Agreement. We may receive up to $15,000,000 in aggregate gross proceeds under the Lincoln Park Purchase Agreement from any sales of the shares of our Common Stock we make to Lincoln Park pursuant to the Lincoln Park Purchase Agreement after the date of this prospectus. We have previously received $1,224,050 in aggregate gross proceeds from prior sales of 2,864,522 shares, including the Initial Commitment Shares, under the Lincoln Park Purchase Agreement. We estimate that the net proceeds to us from the sale of the Lincoln Park Shares to Lincoln Park pursuant to the Lincoln Park Purchase Agreement will be up to $2,493,750 assuming that we sell the full amount of Lincoln Park Shares offered by this prospectus and assuming an average purchase price of $0.1164 per share (which was the closing price of our Common Stock on the Nasdaq Capital Market on February 28, 2024), and after other estimated fees and expenses. Depending on the market prices of our Common Stock and other factors, we may sell more (subject to certain requirements) or fewer than all of the shares offered by this prospectus, in which case our net offering proceeds may be more or less. In addition, because we are not obligated to sell any shares of our Common Stock under the Lincoln Park Purchase Agreement, other than the Commitment Shares, the actual total offering amount and proceeds to us, if any, are not determinable at this time. There can be no assurance that we will receive any proceeds under or fully utilize the Lincoln Park Purchase Agreement. See “Plan of Distribution” elsewhere in this prospectus for more information. Any proceeds that we receive from such sales of the Lincoln Park Shares will be used for working capital and general corporate purposes, which may include acquisitions, investments in or licenses of complementary products, technologies or businesses, operating expenses and capital expenditures. Our management will retain broad discretion in the allocation of the net proceeds from any sale of the Lincoln Park Shares.

We may also receive cash proceeds equal to the total exercise price of the Warrants issued to Mount Sinai to the extent any of such Warrants are exercised for cash. The exercise price of the MTS Warrants is $0.5060 per share of Common Stock and the exercise price of the MTS Pre-Funded Warrants is $0.00001. The exercise price and the number of shares of Common Stock issuable upon exercise of the Warrants may be adjusted in certain circumstances, including stock splits, dividends or distributions, or other similar transactions. The Warrants contain a “cashless exercise” feature that allows the holders to exercise any of such Warrants without making a cash payment to us if there is not an effective registration statement covering the resale of the shares issuable upon exercise of such Warrants. There can be no assurance that any of the Warrants will be exercised by the Selling Stockholders at all. To the extent we receive proceeds from the cash exercise of the Warrants, we intend to use such proceeds for working capital and general corporate purposes, which may include acquisitions, investments in or licenses of complementary products, technologies or businesses, operating expenses and capital expenditures. Our management will retain broad discretion in the allocation of the net proceeds from any exercise of the Warrants for cash.

The Selling Stockholders will pay any underwriting discounts, selling commissions or transfer taxes incurred in disposing of the Shares and the expenses of any attorney or other advisor they decide to employ. We will bear all other costs, fees and expenses incurred in effecting the registration of the Shares covered by this prospectus. These may include, without limitation, all registration, filing, stock exchange fees, printing expenses, all fees and expenses of complying with applicable securities laws and the fees and disbursements of our counsel and of our independent accountants and reasonable fees.

MARKET FOR COMMON STOCK AND DIVIDEND POLICY

Our Common Stock is traded on the Nasdaq Capital Market under the symbol “HSCS.” The last reported sale price of our Common Stock on February 28, 2024 on the Nasdaq Capital Market was $0.1164 per share. As of February 28, 2024, there were 295 holders of record of our Common Stock.

We have never declared or paid any cash dividends on our capital stock. We currently intend to retain any future earnings to fund the development and expansion of our business, and therefore we do not anticipate paying cash dividends on our Common Stock in the foreseeable future. Any future determination to pay dividends will be at the discretion of our Board of Directors and will depend on our results of operations, financial condition, capital requirements, contractual restrictions and other factors deemed relevant by our Board of Directors.

SELLING STOCKHOLDERS TRANSACTIONS

Mount Sinai

On September 20, 2023, we entered into multiple definitive License Agreements with 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. The License Agreements, of which there are eleven in total, cover rights to thirteen AI-ECG cardiovascular algorithms, two data science methods for use with ECG waveforms and three filed patents.

On November 15, 2023, we closed the transactions contemplated under the Mount Sinai Securities Purchase Agreement and the Licenses under the License Agreements, which became effective on that date. On November 16, 2023 and pursuant to the Mount Sinai Securities Purchase Agreement, we issued to Mount Sinai the following:

• 4,854,853 shares of Common Stock (the “Consideration Shares” and collectively with the MTS Warrants and the MTS Pre-Funded Warrants, the “MTS Securities”);

• The MTS Pre-Funded Warrants to purchase up to 710,605 shares of Common Stock, with an exercise price per share of $0.00001, which warrants were issued in lieu of shares of Common Stock issuable to Mount Sinai to ensure that the number of shares of Common Stock held by Mount Sinai does not exceed the Beneficial Ownership Limitation; and

• The MTS Warrants to purchase up to 914,148 shares of Common Stock, having an exercise price per share equal to $0.5060.

Lincoln Park Transaction

General

On March 10, 2023, we entered into the Lincoln Park Purchase Agreement with Lincoln Park pursuant to which we have the right, but not the obligation, to sell to Lincoln Park up to $15,000,000 of the Purchase Shares from time to time over a 36-month term beginning only after certain conditions set forth in the Lincoln Park Purchase Agreement have been satisfied, including that the Lincoln Park Registration Statement shall have been declared effective under the Securities Act. In accordance with the Lincoln Park Purchase Agreement, on March 13, 2023, we issued the Initial Commitment Shares to Lincoln Park as consideration for its commitment to purchase the Purchase Shares under the Lincoln Park Purchase Agreement. As a result of Lincoln Park’s purchases cumulatively reaching an aggregate amount of $2,000,000 of Purchase Shares, in accordance with the Lincoln Park Purchase Agreement, we will issue an additional 62,500 shares of our Common Stock to Lincoln Park as consideration for such purchases.

As of February 28, 2024, we have issued 2,864,522 shares to Lincoln Park, including the Initial Commitment Shares, receiving gross proceeds of approximately $1.2 million.

Table of Contents

We may, from time to time and at our sole discretion, subject to the Beneficial Ownership Limitation, direct Lincoln Park to purchase shares of our Common Stock upon the satisfaction of certain conditions set forth in the Lincoln Park Purchase Agreement at a purchase price per share based on the market price of our Common Stock at the time of sale as computed under the Lincoln Park Purchase Agreement. Lincoln Park may not assign or transfer its rights and obligations under the Lincoln Park Purchase Agreement.

On January 17, 2024, we obtained shareholder approval to issue to Lincoln Park, pursuant to the Lincoln Park Purchase Agreement, shares of our Common Stock, including the Commitment Shares, which exceed 1,927,022 shares, which was then equal to 19.99% of the shares of our Common Stock outstanding immediately prior to the execution of the Lincoln Park Purchase Agreement. The Lincoln Park Purchase Agreement also prohibits us from directing Lincoln Park to purchase any shares of our Common Stock if those shares, when aggregated with all other shares of our Common Stock then beneficially owned by Lincoln Park, would result in Lincoln Park and its affiliates’ exceeding the Beneficial Ownership Limitation.

Purchase of Shares under the Purchase Agreement

Regular Purchases

After the Commencement Date, on any business day selected by us, we may direct Lincoln Park to purchase up to 50,000 shares of our Common Stock on such business day (or the purchase date), which we refer to as a Regular Purchase, provided that the closing sale price of our Common Stock on Nasdaq is not below $0.10 on the applicable purchase date, and provided, further, that (i) a Regular Purchase shall be increased to up to 75,000 shares if the closing sale price of our Common Stock on Nasdaq is not below $0.75 on the applicable purchase date, (ii) a Regular Purchase shall be increased to up to 100,000 shares if the closing sale price of our Common Stock on Nasdaq is not below $1.00 on the applicable purchase date, (iii) a Regular Purchase shall be increased to up to 150,000 shares if the closing sale price of our Common Stock on Nasdaq is not below $2.00 on the applicable purchase date, (iv) a Regular Purchase shall be increased to up to 200,000 shares if the closing sale price of our Common Stock on Nasdaq is not below $2.50 on the applicable purchase date. However, we may not direct Lincoln Park to purchase more than $750,000 in shares under any single Regular Purchase.

The purchase price per share for each such Regular Purchase will be equal to the lesser of:

• the lowest sale price for our Common Stock on the purchase date of such shares; and

• the average of the three lowest closing sale prices for our Common Stock during the ten (10) consecutive business days prior to the purchase date of such shares.

Accelerated Purchases

We may also direct Lincoln Park, subject to the Beneficial Ownership Limitation, on any business day on which we have properly submitted a Regular Purchase notice to purchase an additional amount of our Common Stock (an “Accelerated Purchase”) of up to the lesser of:

• three times the number of shares purchased pursuant to such Regular Purchase; or

• 30% of the aggregate shares of our Common Stock traded during all or, if certain trading volume or market price thresholds specified in the Lincoln Park Purchase Agreement are crossed on the applicable Accelerated Purchase date, the portion of the normal trading hours on the applicable Accelerated Purchase date prior to such time that any one of such thresholds is crossed, which period of time on the applicable Accelerated Purchase date (the “Accelerated Purchase Measurement Period”).

The purchase price per share for each such Accelerated Purchase will be equal to the lesser of 97% of:

• the volume-weighted average price of our Common Stock during the applicable Accelerated Purchase Measurement Period on the applicable Accelerated Purchase date; and

• the closing sale price of our Common Stock on the applicable Accelerated Purchase date.

Table of Contents

Additional Accelerated Purchases

We may also direct Lincoln Park, subject to the Beneficial Ownership Limitation, on any business day on which an Accelerated Purchase has been completed and all of the shares to be purchased thereunder have been properly delivered to Lincoln Park in accordance with the Purchase Agreement, to purchase an additional amount of our Common Stock (an “Additional Accelerated Purchase”), of up to the lesser of:

• three times the number of shares purchased pursuant to such Regular Purchase; or

• 30% of the aggregate shares of our Common Stock traded during a certain portion of the normal trading hours on the applicable Additional Accelerated Purchase date as determined in accordance with the Purchase Agreement, which period of time on the applicable Additional Accelerated Purchase date we refer to as the “Additional Accelerated Purchase Measurement Period”.

We may, in our sole discretion, subject to the Beneficial Ownership Limitation, submit multiple Additional Accelerated Purchase notices to Lincoln Park on a single Accelerated Purchase date, provided that all prior Accelerated Purchases and Additional Accelerated Purchases (including those that have occurred earlier on the same day) have been completed and all of the shares to be purchased thereunder have been properly delivered to Lincoln Park in accordance with the Purchase Agreement.

The purchase price per share for each such Additional Accelerated Purchase will be equal to the lesser of 97% of:

• the volume weighted average price of our Common Stock during the applicable Additional Accelerated Purchase Measurement Period on the applicable Additional Accelerated Purchase date; and

• the closing sale price of our Common Stock on the applicable Additional Accelerated Purchase date.

In the case of the Regular Purchases, Accelerated Purchases and Additional Accelerated Purchases, the purchase price per share will be equitably adjusted for any reorganization, recapitalization, non-cash dividend, stock split, reverse stock split or other similar transaction occurring during the business days used to compute the purchase price.

Other than the Beneficial Ownership Limitation and as described above, there are no trading volume requirements or restrictions under the Purchase Agreement, and we will control the timing and amount of any sales of our Common Stock to Lincoln Park.

Suspension Events

Suspension Events under the Lincoln Park Purchase Agreement include the following:

• the effectiveness of the registration statement of which this prospectus forms a part lapses for any reason (including, without limitation, the issuance of a stop order), or any required prospectus is unavailable for the resale by Lincoln Park of our Common Stock offered hereby, and such lapse or unavailability continues for a period of 10 consecutive business days or for more than an aggregate of 30 business days in any 365-day period, but excluding a lapse or unavailability where (i) we terminate a registration statement after Lincoln Park has confirmed in writing that all of the shares of our Common Stock covered thereby have been resold or (ii) we supersede one registration statement with another registration statement, including (without limitation) by terminating a prior registration statement when it is effectively replaced with a new registration statement covering the shares of our Common Stock covered by the Lincoln Park Purchase Agreement (provided in the case of this clause (ii) that all of the shares of our Common Stock covered by the superseded (or terminated) registration statement that have not theretofore been resold are included in the superseding (or new) registration statement);

• suspension by our principal market of our Common Stock from trading for a period of one business day;

• the de-listing of our Common Stock from the Nasdaq Capital Market, our principal market, provided, our Common Stock is not immediately thereafter trading on the New York Stock Exchange, the Nasdaq Global Market, the Nasdaq Global Select Market, the NYSE American, the NYSE Arca, the OTC Bulletin Board, the OTCQX or the OTCQB operated by the OTC Markets Group, Inc. (or nationally recognized successor to any of the foregoing);

Table of Contents

• the failure for any reason by our transfer agent to issue purchased shares of our Common Stock to Lincoln Park within two business days after the purchase date, Accelerated Purchase date or Additional Accelerated Purchase date, as applicable, on which Lincoln Park is entitled to receive such purchased shares;

• any breach of the representations, warranties, covenants or other terms or conditions contained in the Lincoln Park Purchase Agreement or the Lincoln Park Registration Rights Agreement that has or could have a Material Adverse Effect (as defined in the Lincoln Park Purchase Agreement) and, in the case of a breach of a covenant that is reasonably curable, that is not cured within a period of at least five business days;

• our Common Stock ceases to be DTC authorized and ceases to participate in the DWAC/FAST systems; or

• any voluntary or involuntary participation or threatened participation in insolvency or bankruptcy proceedings by or against us.

Lincoln Park does not have the right to terminate the Lincoln Park Purchase Agreement upon any of the suspension events set forth above; however, the Lincoln Park Purchase Agreement will automatically terminate upon initiation of insolvency or bankruptcy proceedings by or against us. During any suspension event, or if any event that, after notice and/or lapse of time, would reasonably be expected to become a suspension event, has occurred and is continuing, all of which are outside of Lincoln Park’s control, we may not direct Lincoln Park to purchase any shares of our Common Stock under the Lincoln Park Purchase Agreement.

Our Termination Rights

We have the unconditional right, at any time, for any reason and without any payment or liability to us, to give notice to Lincoln Park to terminate the Purchase Agreement.

No Short-Selling or Hedging by Lincoln Park

Lincoln Park has agreed that neither it nor any of its affiliates shall engage in any direct or indirect short-selling or hedging of our Common Stock during any time prior to the termination of the Lincoln Park Purchase Agreement.

Prohibitions on Variable Rate Transactions

Subject to specified exceptions included in the Lincoln Park Purchase Agreement, we are limited in our ability to enter into specified variable rate transactions during the term of the Lincoln Park Purchase Agreement. Such transactions include, among others, the issuance of convertible securities with a conversion or exercise price that is based upon or varies with the trading price of our Common Stock after the date of issuance, the issuance of securities with embedded anti-dilution provisions, the issuance of securities with an embedded put or call right or at a price subject to being reset after the initial issuance contingent on our business or market performance.

Effect of Performance of the Purchase Agreement on our Stockholders

All shares registered in this offering that have been or may be issued or sold by us to Lincoln Park under the Lincoln Park Purchase Agreement are expected to be freely tradable. Such shares registered in this offering may be sold over a period of up to approximately 26 months commencing on the date of this prospectus. The sale by Lincoln Park of a significant amount of shares registered in this offering at any given time could cause the market price of our Common Stock to decline and be highly volatile. Sales of our Common Stock to Lincoln Park, if any, will depend upon market conditions and other factors to be determined by us. We may ultimately decide to sell to Lincoln Park all, some or none of the additional shares of our Common Stock that may be available for us to sell pursuant to the Purchase Agreement. If and when we do sell shares to Lincoln Park, after Lincoln Park has acquired the shares, Lincoln Park may resell all, some or none of those shares at any time or from time to time in its discretion. Therefore, sales to Lincoln Park by us under the Lincoln Park Purchase Agreement may result in substantial dilution to the interests of other holders of our Common Stock. In addition, if we sell a substantial number of shares to Lincoln Park under the Lincoln Park Purchase Agreement, or if investors expect that we will do so, the actual sales of shares or the mere existence of our arrangement with Lincoln Park may make it more difficult for us to sell equity or equity-related securities in the future at a time and at a price that we might otherwise wish to effect such sales. However, we have the right to control the timing and amount of any additional sales of our shares to Lincoln Park and the Lincoln Park Purchase Agreement may be terminated by us at any time at our discretion without any cost to us.

Table of Contents

Pursuant to the terms of the Lincoln Park Purchase Agreement, we have the right, but not the obligation, subject to the Beneficial Ownership Limitation, to direct Lincoln Park to purchase up to $15,000,000 of our Common Stock, exclusive of the Initial Commitment Shares issued to Lincoln Park on the date of the Lincoln Park Purchase Agreement. The Lincoln Park Purchase Agreement prohibits us from issuing or selling to Lincoln Park under the Lincoln Park Purchase Agreement any shares of our Common Stock if those shares, when aggregated with all other shares of our Common Stock then beneficially owned by Lincoln Park, would exceed the Beneficial Ownership Limitation. On January 17, 2024, we obtained shareholder approval to issue to Lincoln Park, pursuant to the Lincoln Park Purchase Agreement, shares of our Common Stock, including the Commitment Shares, which may exceed the Beneficial Ownership Cap.

The following table sets forth the amount of gross proceeds we would receive from Lincoln Park from our sale of shares to Lincoln Park under the Purchase Agreement at varying purchase prices:

(2) The denominator is based on 65,161,630 shares outstanding as of February 28, 2024, adjusted to include the issuance of (i) the Commitment Shares issued to Lincoln Park upon the execution of the Lincoln Park Purchase Agreement and (ii) the number of shares set forth in the adjacent column that we would have sold to Lincoln Park, assuming the average purchase price in the first column.

(3) The closing sale price of our Common Stock on February 28, 2024.

John Q. Adams

In April 2020, we entered into the $1M Loan and Security Agreement, with FRV and Adams (a former director of our Company). Each of FRV and Adams committed to lend a principal amount of $500,000, totaling $1 million, evidenced by secured, non-convertible promissory notes that we refer to as the $1M Notes. The loan was drawn in three installments of $300,000 upon execution of the $1M Loan and Security Agreement, $350,000 in July 2020 and $350,000 in September 2020. The loan accrued interest at a rate of 12% per annum, compounded annually, which is payable at maturity. We were also required to pay default interest at a rate of 18% per annum, compounded annually, on any unpaid amounts due at maturity until the loan amounts are fully repaid. The loan is secured by substantially all of the Company’s assets and intellectual property.

The loan had an original maturity date of September 30, 2021, which was amended on September 30, 2021, making the note repayable on demand. The loan was amended on November 3, 2021, extending the maturity to September 30, 2022; further amended in May 2022 to extend the maturity date to September 30, 2023; amended again in January 2023 to (i) further extend the maturity date of the portion of the $1M Notes issued to one lender (in the principal amount of $0.5 million) to March 31, 2024 and (ii) further extend the maturity date of the remaining portion of the $1M Notes issued to the other lender (in the principal amount of $0.5 million) to September 30, 2024. The $1M Loan and Security Agreement was further amended in September 2023 to extend the interest maturity date to one lender to December 31, 2023. In October 2023, we issued additional $1M Lender Warrants to purchase 200,000 shares of our Common Stock to lenders of the $1M Notes as consideration for the extension of the interest maturity date

Table of Contents

to one lender. On November 16, 2023, we entered into the Adams Warrant Amendment, amending the $1M Lender Warrants owned by Adams to reduce the exercise price of an aggregate of 107,575 $1M Lender Warrants to $0.16 per share. The exercise prices of the $1M Lender Warrants range from $0.16 to $2.89 per share as of February 28, 2024.

Matthews Southwest Holdings, Inc.

On August 12, 2021, we issued a note for the amount of $500,000 to Matthews, a beneficial owner owning more than 5% of our Common Stock. The maturity date of this note, as amended, was November 30, 2021. This note has been repaid and there are no further obligations owed by our Company. In connection with the issuance of this note, we also issued 10,101 shares of our Common Stock as a facility fee for the note to Matthews.

On September 7, 2023, we entered into the MSW Note with Matthews. The MSW Note provided for an unsecured drawdown loan of up to $1,000,000. As of November 14, 2023, the Company had drawn $500,000 under the MSW Note and issued 1,000,000 Existing MSW Warrants to purchase shares of Common Stock in lieu of certain fees payable under the MSW Note.

On November 15, 2023, we entered into the Note Conversion Letter Agreements with MSW and Adams (collectively, the “Lenders”). On November 16, 2023, pursuant to the Note Conversion Letter Agreements, in consideration for the conversion of the aggregate principal and interest amount due under the Notes, we: (1) issued an aggregate of 6,781,288 shares of Common Stock to the Lenders, comprised of (a) 3,125,000 shares of Common Stock to MSW and (b) 3,656,288 shares of Common Stock issued to Adams; (2) entered into the MSW Warrant Amendment with MSW, amending the Existing MSW Warrants to reduce the exercise price of an aggregate of 1,000,000 Existing MSW Warrants to $0.16 per share; and (3) entered into the Adams Warrant Amendment, amending the $1M Lender Warrants owned by Adams to reduce the exercise price of an aggregate of 107,575 $1M Lender Warrants to $0.16 per share. Except as expressly set forth in the MSW Warrant Amendment and the Adams Warrant Amendment, the terms and provisions of the warrants held by the Lenders shall remain in full force and effect.

SELLING STOCKHOLDERS

Unless the context otherwise requires, as used in this prospectus, “Selling Stockholders” includes the selling stockholders listed below and donees, pledgees, transferees or other successors-in-interest selling shares received after the date of this prospectus from a selling stockholder as a gift, pledge or other non-sale related transfer.

We have prepared this prospectus to allow the Selling Stockholders or their successors, assignees or other permitted transferees to sell or otherwise dispose of, from time to time, up to 34,684,859 shares of our Common Stock, which consist of: (i) 4,854,853 Mount Sinai Shares, (ii) 710,605 shares of Common Stock issuable upon the exercise of the MTS Pre-Funded Warrants, (iii) 914,148 shares of Common Stock issuable upon the exercise of the MTS Warrants, (iv) up to 21,423,965 Lincoln Park Shares issuable to Lincoln Park from time to time over approximately the next 26 months, at our sole discretion, in accordance with the Lincoln Park Purchase Agreement, (v) 3,656,288 Adams Shares issued to Adams pursuant to the Adams Note Conversion Letter Agreement, and (vi) 3,125,000 Matthews Shares issued to Matthews pursuant to the Matthews Note Conversion Letter Agreement.

The MTS Pre-Funded Warrants were exercisable by Mount Sinai immediately upon issuance, will survive until they are exercised in full and have an exercise price, which was pre-funded on September 20, 2023, of $0.00001 per share of Common Stock, subject to adjustment for stock splits, reverse stock splits, stock dividends and similar transactions. The MTS Warrants have an exercise price per share equal to $0.5060. Under the terms of the MTS Warrants, Mount Sinai may not exercise such MTS Warrants to the extent such exercise would cause Mount Sinai, together with its affiliates, to beneficially own a number of shares of our Common Stock which would exceed 4.99% of our then outstanding Common Stock following such exercise, excluding for purposes of such determination Common Stock issuable upon exercise of such MTS Warrants which have not been exercised. Under the terms of the MTS Pre-Funded Warrants, Mount Sinai may not exercise such Mount Sinai Pre-Funded Warrant to the extent such exercise would cause Mount Sinai, together with its affiliates, to beneficially own a number of shares of Common Stock which would exceed 9.99% of our then outstanding Common Stock following such exercise, excluding for purposes of such determination Common Stock issuable upon exercise of such Mount Sinai Pre-Funded Warrant which have not been exercised.

The Shares were issued or will be issuable to the Selling Stockholders in reliance on the exemption from securities registration in Section 4(a)(2) under the Securities Act and Rule 506 promulgated thereunder or Regulation S, to the extent applicable.

The shares of Common Stock to be offered by the Selling Stockholders are “restricted” securities under applicable federal and state securities laws and are being registered under the Securities Act to give the Selling Stockholders the opportunity to sell these shares publicly. The registration of these shares does not require that any of the shares be offered or sold by the Selling Stockholders. Subject to these resale restrictions, the Selling Stockholders may from time to time offer and sell all or a portion of their shares indicated below in privately negotiated transactions or on the Nasdaq Capital Market or any other market on which our Common Stock may subsequently be listed.

The registered shares may be sold directly or through brokers or dealers, or in a distribution by one or more underwriters on a firm commitment or best effort basis. To the extent required, the names of any agent or broker-dealer and applicable commissions or discounts and any other required information with respect to any particular offering will be set forth in a prospectus supplement. See the section of this prospectus entitled “Plan of Distribution”. The Selling Stockholders and any agents or broker-dealers that participate with the Selling Stockholders in the distribution of registered shares may be deemed to be “underwriters” within the meaning of the Securities Act, and any commissions received by them and any profit on the resale of the registered shares may be deemed to be underwriting commissions or discounts under the Securities Act.

No estimate can be given as to the amount or percentage of Common Stock that will be held by the Selling Stockholders after any sales made pursuant to this prospectus because the Selling Stockholders are not required to sell any of the Shares being registered under this prospectus. The following table assumes that the Selling Stockholders will sell all of the Shares listed in this prospectus.

Unless otherwise indicated in the footnotes below, no Selling Stockholder has had any material relationship with us or any of our affiliates within the past three years other than as a security holder.

We have prepared this table based on written representations and information furnished to us by or on behalf of the Selling Stockholders or information available to us. Since the date on which the Selling Stockholders provided this information, the Selling Stockholders may have sold, transferred or otherwise disposed of all or a portion of the

Table of Contents

shares of Common Stock in a transaction exempt from the registration requirements of the Securities Act. Unless otherwise indicated in the footnotes below, we believe that: (1) none of the Selling Stockholders are broker-dealers or affiliates of broker-dealers, (2) no Selling Stockholder has direct or indirect agreements or understandings with any person to distribute their Shares, and (3) the Selling Stockholders have sole voting and investment power with respect to all Shares beneficially owned, subject to applicable community property laws. To the extent any Selling Stockholder identified below is, or is affiliated with, a broker-dealer, it could be deemed, individually but not severally, to be an “underwriter” within the meaning of the Securities Act. Information about the Selling Stockholders may change over time. Any changed information will be set forth in supplements to this prospectus, if required.

The following table sets forth information with respect to the beneficial ownership of our Common Stock held, as of February 28, 2024, by the Selling Stockholders and the number of Shares being registered hereby and information with respect to shares to be beneficially owned by the Selling Stockholders after completion of the offering of the shares for resale. We have determined beneficial ownership in accordance with the rules of the SEC. The inclusion of any shares in this table does not constitute an admission of beneficial ownership by the persons named below. The percentages in the following table reflect the shares beneficially owned by the Selling Stockholders as a percentage of the total number of shares of Common Stock outstanding as of February 28, 2024. As of such date, 65,161,630 shares of Common Stock were outstanding.

PLAN OF DISTRIBUTION

Pursuant to this prospectus, (i) we are registering the shares of our Common Stock previously issued to certain Selling Stockholders, and the shares of our Common Stock issuable upon exercise of the Warrants previously issued to certain Selling Stockholders to permit the resale of these shares of Common Stock by the holders of the Shares and the Warrants from time to time after the date of this prospectus, and (ii) we are offering up to 21,423,965 shares of our Common Stock that may be issued to Lincoln Park pursuant to the Lincoln Park Purchase Agreement.

General

The Selling Stockholders may sell all or a portion of the shares of our Common Stock beneficially owned by them and offered hereby from time to time directly or through one or more underwriters, broker-dealers or agents. If the shares of our Common Stock are sold through underwriters or broker-dealers, the Selling Stockholders will be responsible for underwriting fees, discounts or commissions or agent’s commissions. The shares of our Common Stock may be sold by the Selling Stockholders in one or more transactions at fixed prices, at prevailing market prices at the time of the sale, at varying prices determined at the time of sale, or at negotiated prices. The Selling Stockholders will act independently of us in making decisions with respect to the timing, manner and size of each sale. These sales may be effected in transactions, which may involve cross or block transactions:

• on any national securities exchange or quotation service on which the securities may be listed or quoted at the time of sale;

• in the over-the-counter market;

• in transactions otherwise than on these exchanges or systems or in the over-the-counter market;

• through the writing of options, whether such options are listed on an options exchange or otherwise;

• in ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers;

• in block trades in which the broker-dealer will attempt to sell the shares as agent but may position and resell a portion of the block as principal to facilitate the transaction;

• through purchases by a broker-dealer as principal and resale by the broker-dealer for its account;

• in an exchange distribution in accordance with the rules of the applicable exchange;

• in privately negotiated transactions;

• in short sales;

• through the distribution of our Common Stock by any Selling Stockholder to its partners, members or stockholders;

• through one or more underwritten offerings on a firm commitment or best efforts basis;

• in sales pursuant to Rule 144;

• whereby broker-dealers may agree with any Selling Stockholders to sell a specified number of such shares at a stipulated price per share;

• in a combination of any such methods of sale; and

• in any other method permitted pursuant to applicable law.

If any Selling Stockholders effect such transactions by selling shares of our Common Stock to or through underwriters, broker-dealers or agents, such underwriters, broker-dealers or agents may receive commissions in the form of discounts, concessions or commissions from the Selling Stockholders or commissions from purchasers of the shares of our Common Stock for whom they may act as agent or to whom they may sell as principal (which discounts,

Table of Contents

concessions or commissions as to particular underwriters, broker-dealers or agents may be in excess of those customary in the types of transactions involved). In connection with sales of the shares of our Common Stock or otherwise, the Selling Stockholders may enter into hedging transactions with broker-dealers, which may in turn engage in short sales of the shares of Common Stock in the course of hedging in positions they assume. The Selling Stockholders may also sell shares of Common Stock short and deliver shares of Common Stock covered by this prospectus to close out short positions and to return borrowed shares in connection with such short sales. The Selling Stockholders may also loan or pledge shares of Common Stock to broker-dealers that in turn may sell such shares. The Selling Stockholders may pledge or grant a security interest in some or all of the shares of Common Stock or Warrants owned by them and, if they default in the performance of their secured obligations, the pledgees or secured parties may offer and sell the shares of Common Stock from time to time pursuant to this prospectus or any amendment to this prospectus under Rule 424(b)(3) or other applicable provision of the Securities Act amending, if necessary, the list of Selling Stockholders to include the pledgee, transferee or other successors in interest as Selling Stockholders under this prospectus. The Selling Stockholders also may transfer and donate the shares of Common Stock in other circumstances in which case the transferees, donees, pledgees or other successors in interest will be the selling beneficial owners for purposes of this prospectus.

The Selling Stockholders, individually and not severally, and any broker-dealer participating in the distribution of the shares of Common Stock may be deemed to be “underwriters” within the meaning of the Securities Act, and any commission paid, or any discounts or concessions allowed to, any such broker-dealer may be deemed to be underwriting commissions or discounts under the Securities Act. At the time a particular offering of the shares of Common Stock is made, a prospectus supplement, if required, will be distributed which will set forth the aggregate amount of shares of Common Stock being offered and the terms of the offering, including the name or names of any broker-dealers or agents, any discounts, commissions and other terms constituting compensation from the Selling Stockholders and any discounts, commissions or concessions allowed or reallowed or paid to broker-dealers. The Selling Stockholders may indemnify any broker-dealer that participates in transactions involving the sale of the shares of Common Stock against certain liabilities, including liabilities arising under the Securities Act.

Under the securities laws of some states, the shares of Common Stock may be sold in such states only through registered or licensed brokers or dealers. In addition, in some states the shares of Common Stock may not be sold unless such shares have been registered or qualified for sale in such state or an exemption from registration or qualification is available and is complied with.

The aggregate proceeds to the Selling Stockholders from the sale of the Common Stock offered will be the purchase price of the Common Stock less discounts or commissions, if any. The Selling Stockholders reserve the right to accept and, together with their agents from time to time, to reject, in whole or in part, any proposed purchase of Common Stock to be made directly or through agents. There can be no assurance that any Selling Stockholder will sell any or all of the shares of Common Stock registered pursuant to the registration statement of which this prospectus forms a part.

The Selling Stockholders and any other person participating in such distribution will be subject to applicable provisions of the Exchange Act and the rules and regulations thereunder, including, without limitation, Regulation M of the Exchange Act, which may limit the timing of purchases and sales of any of the shares of Common Stock by the Selling Stockholders and any other participating person. Regulation M may also restrict the ability of any person engaged in the distribution of the shares of Common Stock to engage in market-making activities with respect to the shares of Common Stock. All of the foregoing may affect the marketability of the shares of Common Stock and the ability of any person or entity to engage in market-making activities with respect to the shares of Common Stock.

We will incur costs, fees and expenses in effecting the registration of the Shares covered by this prospectus, estimated to be approximately $41,000 in total, including, without limitation, all registration, filing, stock exchange fees, printing expenses, all fees and expenses of complying with applicable securities laws and the fees and disbursements of our counsel and of our independent registered public accounting firm and reasonable fees, provided, however, that a Selling Stockholder will pay all underwriting discounts, selling commissions or transfer taxes, if any. We will indemnify the Selling Stockholders against certain liabilities, including certain liabilities arising under the Securities Act or the Exchange Act. We may be indemnified by certain of the Selling Stockholders against certain liabilities, including certain liabilities arising under the Securities Act or the Exchange Act, that may arise from any written information furnished to us by a Selling Stockholder specifically for use in this prospectus.

Once sold under the registration statement, of which this prospectus forms a part, the shares of Common Stock will be freely tradable in the hands of persons other than our affiliates.

Lincoln Park Transaction

We may, from time to time and at our sole discretion, subject to the Beneficial Ownership Limitation, direct Lincoln Park to purchase shares of our Common Stock in amounts up to 50,000 shares on any single business day, subject to a maximum of $750,000 per purchase. In addition, upon notice to Lincoln Park, we may, from time to time and at our sole discretion, subject to the Beneficial Ownership Limitation, direct Lincoln Park to purchase additional shares of our Common Stock in “accelerated purchases,” and/or “additional accelerated purchases” as set forth in the Lincoln Park Purchase Agreement and described above in the section captioned “Selling Stockholders Transactions”. The purchase price per share is based on the market price of our Common Stock at the time of sale as computed under the Lincoln Park Purchase Agreement. Lincoln Park may not assign or transfer its rights and obligations under the Purchase Agreement. See “Selling Stockholders Transactions — Lincoln Park Transaction — Purchase of Shares under the Purchase Agreement.”

Lincoln Park is an “underwriter” within the meaning of Section 2(a)(11) of the Securities Act.

We will pay the expenses incident to the registration under the Securities Act of the offer and sale of the shares covered by this prospectus to Lincoln Park. We have agreed to indemnify Lincoln Park and certain other persons against certain liabilities in connection with the offering of shares of our Common Stock offered hereby, including liabilities arising under the Securities Act or, if such indemnity is unavailable, to contribute amounts required to be paid in respect of such liabilities. Lincoln Park has agreed to indemnify us against liabilities under the Securities Act that may arise from certain written information furnished to us by Lincoln Park specifically for use in this prospectus or, if such indemnity is unavailable, to contribute amounts required to be paid in respect of such liabilities.

Lincoln Park has represented to us that at no time prior to the Lincoln Park Purchase Agreement has Lincoln Park or its agents, representatives or affiliates engaged in or effected, in any manner whatsoever, directly or indirectly, any short sale (as such term is defined in Rule 200 of Regulation SHO of the Exchange Act) of our Common Stock or any hedging transaction, which establishes a net short position with respect to our Common Stock. Lincoln Park agreed that during the term of the Lincoln Park Purchase Agreement, it, its agents, representatives or affiliates will not enter into or effect, directly or indirectly, any of the foregoing transactions.

We have advised Lincoln Park that it is required to comply with Regulation M promulgated under the Exchange Act. With certain exceptions, Regulation M precludes Lincoln Park, any affiliated purchasers, and any broker-dealer or other person who participates in the distribution from bidding for or purchasing, or attempting to induce any person to bid for or purchase any security which is the subject of the distribution until the entire distribution is complete. Regulation M also prohibits any bids or purchases made in order to stabilize the price of a security in connection with the distribution of that security. All of the foregoing may affect the marketability of the securities offered by this prospectus.

This offering of the Lincoln Park Shares will terminate on the date that all of the Lincoln Park Shares offered by this prospectus have been sold to Lincoln Park.

DESCRIPTION OF OUR SECURITIES

General

The following description summarizes the terms of our securities and certain provisions of our Certificate of Formation and our Bylaws. As it is only a summary, it does not contain all the information that may be important to you. For a complete description, you should refer to our Certificate of Formation and Bylaws, as in effect as of the date of filing with the SEC of this prospectus, the forms of which are included as exhibits to the registration statement of which this prospectus forms a part.

Our purpose is to engage in any lawful act or activity for which corporations may now or hereafter be organized under the TBOC. Our authorized capital stock consists of five hundred million (500,000,000) shares of Common Stock, par value $0.001 per share, and twenty million (20,000,000) shares of preferred stock, or Preferred Stock, par value $0.001 per share of which, as of February 28, 2024, there were 65,161,630 shares of Common Stock outstanding and held of record by 295 shareholders and 380,440 shares of Series C Preferred Stock outstanding that, as of such date, were convertible into 6,483,709 shares of Common Stock and held of record by 64 shareholders. Of our authorized Preferred Stock, six hundred thousand (600,000) shares have been designated as Series C Preferred Stock, having a par value of $0.001 per share, of which 380,440 were outstanding as of February 28, 2024. Unless our Board of Directors determines otherwise, we have and will continue to issue all shares of our capital stock in uncertificated form.

Common Stock

Holders of our Common Stock are entitled to one vote for each share held of record on all matters on which shareholders are entitled to vote generally, including the election or removal of directors, subject to certain limitations. The holders of our Common Stock do not have cumulative voting rights in the election of directors. Upon our liquidation, dissolution or winding up and after payment in full of all amounts required to be paid to creditors and to the holders of preferred stock having liquidation preferences, if any, the holders of our Common Stock will be entitled to receive pro rata our remaining assets available for distribution on a pro rata basis. Holders of our Common Stock do not have preemptive, subscription, redemption or conversion rights. The Common Stock will not be subject to further calls or assessment by us. There will be no redemption or sinking fund provisions applicable to the Common Stock. All outstanding shares of our Common Stock are fully paid and non-assessable. The rights, powers, preferences and privileges of holders of our Common Stock will be subject to those of the holders of any shares of our Preferred Stock, including any Preferred Stock we may authorize and issue in the future.

As a Texas corporation, we are subject to certain restrictions on dividends under the TBOC. Generally, a Texas corporation may pay dividends to its shareholders out of its surplus (the excess of its assets over its liabilities and stated capital) unless the dividend would render the corporation insolvent.

The declaration, amount and payment of any future dividends will be at the sole discretion of our Board of Directors. Our Board of Directors may take into account general and economic conditions, our financial condition and results of operations, our available cash and current and anticipated cash needs, capital requirements, contractual, legal, tax and regulatory restrictions and implications on the payment of dividends by us to our shareholders.

We currently expect to retain all future earnings for use in the operation and expansion of our business and have no current plans to pay dividends.

Preferred Stock

Our Certificate of Formation authorizes our Board of Directors to establish one or more series of Preferred Stock (including convertible Preferred Stock). Unless required by law or by the TBOC, the authorized shares of Preferred Stock will be available for issuance without further action by our shareholders.

Our Board of Directors will be able to determine, with respect to any series of Preferred Stock, the powers including preferences and relative participations, optional or other special rights, and the qualifications, limitations or restrictions thereof, of that series, including, without limitation:

• the designation of the series;

• the number of shares of the series, which our Board of Directors may, except where otherwise provided in the preferred stock designation, increase (but not above the total number of authorized shares of the class) or decrease (but not below the number of shares then outstanding);

Table of Contents

• whether dividends, if any, will be cumulative or non-cumulative and the dividend rate of the series;

• the dates at which dividends, if any, will be payable;

• the redemption rights and price or prices, if any, for shares of the series;

• the terms and amounts of any sinking fund provided for the purchase or redemption of shares of the series;

• the amounts payable on shares of the series in the event of any voluntary or involuntary liquidation, dissolution or winding-up of the affairs of the Company;

• whether the shares of the series will be convertible into shares of any other class or series, or any other security, of the Company or any other corporation and, if so, the specification of the other class or series or other security, the conversion price or prices or rate or rates, any rate adjustments, the date or dates as of which the shares will be convertible and all other terms and conditions upon which the conversion may be made;

• restrictions on the issuance of shares of the same series or of any other class or series; and

• the voting rights, if any, of the holders of the series.

We will be able to issue a series of Preferred Stock that could, depending on the terms of the series, impede or discourage an acquisition attempt or other transaction that some, or a majority, of the holders of our Common Stock might believe to be in their best interests or in which the holders of our Common Stock might receive a premium for their Common Stock over the market price of the Common Stock. In addition, the issuance of Preferred Stock may adversely affect the rights of holders of our Common Stock by restricting dividends on the Common Stock, diluting the voting power of the Common Stock or subordinating the liquidation rights of the Common Stock. As a result of these or other factors, the issuance of Preferred Stock may have an adverse impact on the market price of our Common Stock.

Series C Preferred Stock

As of February 28, 2024, there were 380,440 shares of Series C Preferred Stock outstanding that, as of such date, were convertible into 6,483,709 shares of Common Stock. As of February 28, 2024, there were no shares of Series A Preferred Stock or Series B Preferred Stock outstanding.

The Series C Preferred Stock was issued from April 2019 to October 2020 to accredited investors and has a liquidation preference to the Common Stock. As of February 28, 2024, the liquidation preference was approximately $9.5 million. Any amendment to, or waiver of rights of the Series C Preferred Stock must include the consent of FRV, so long as FRV holds at least 71,000 shares of Series C Preferred Stock. Additionally, pursuant to a letter agreement entered into by and between the Company and FRV on April 10, 2019, for so long as FRV holds at least 71,000 shares of Series C Preferred Stock, it is entitled to appoint a member of the Board of Directors as well as a board observer (the “Appointment Rights”). As of February 28, 2024, FRV has not exercised its Appointment Rights.

Voting and Dividends

The holders of the shares of the Series C Preferred Stock have voting rights equal to an equivalent number of shares of the Common Stock into which such shares of Series C Preferred Stock are convertible and vote together as one class with the Common Stock.

The holders of the Series C Preferred Stock are entitled to receive dividends at an annual rate of $1.50 per share. Such dividends shall accrue and are payable out of funds legally available, are payable only when and if declared by the Board of Directors and are noncumulative. The Company is not permitted to declare, pay or set aside any dividends on shares of any other class or series of capital stock of the Company (other than dividends on shares of the Common Stock payable in shares of Common Stock) unless the holders of the shares of the Series C Preferred Stock then outstanding first receive, or simultaneously receive, a dividend on each outstanding share of the Series C Preferred Stock in an amount at least equal to the greater of (i) the amount of the aggregate dividends then accrued on such share of the Series C Preferred Stock and not previously paid and (ii) in the case of a dividend on the Common Stock or any class or series that is convertible into Common Stock, that dividend per share of Series C Preferred Stock as would

Table of Contents

equal the product of (1) the dividend payable on each share of such class or series determined, if applicable, as if all shares of such class or series had been converted into Common Stock and (2) the number of shares of Common Stock issuable upon conversion of a share of the Series C Preferred Stock.

No dividends have been declared to date on any shares of Preferred Stock.

Liquidation

In the event of any liquidation, dissolution or winding up of the Company, either voluntarily or involuntarily, the holders of the Series C Preferred Stock are entitled to receive, prior and in preference to the holders of the Common Stock, a per share amount equal to the original issue price ($25.00 per share) plus any accrued but unpaid dividends thereon.

If upon the liquidation, dissolution or winding up of the Company, the assets of the Company that are legally available for distribution to the holders of the Series C Preferred Stock are insufficient to permit the payment to such holders of the full amounts above, then the entire assets of the Company that are legally available for distribution shall be distributed with equal priority and pro rata among the holders of the Series C Preferred Stock in proportion to what they would otherwise be entitled to receive.

After the payment of the full Series C Preferred Stock liquidation preference and unpaid accrued dividends, the holders of the Series C Preferred Stock shall participate in the distribution of the entire remaining assets of the Company legally available for distributions pro rata to holders of the Common Stock on an as converted basis. The sale of a majority of the capital stock of the Company or the sale, lease, transfer, exclusive license or other disposition, in a single transaction or series of related transactions, by the Company or any subsidiary of the Company of all or substantially all the assets of the Company and its subsidiaries taken as a whole shall be a “Deemed Liquidation Event” for the purpose of the Series C Preferred Stock.

Conversion

Each share of Series C Preferred Stock is convertible, at the option of the holder, at any time after the date of issuance of such share, into such number of fully paid and non-assessable shares of Common Stock determined by dividing the original issue price of $25.00 by the conversion price for such series in effect at the time of conversion for the Series C Preferred Stock. The conversion price for the Series C Preferred Stock is subject to adjustment in accordance with conversion provisions contained in our Certificate of Designations, Number, Voting Power, Preferences and Rights of Series C Convertible Preferred Stock dated March 12, 2019. As of February 28, 2024, the conversion price of the Series C Preferred Stock was $1.47 per share. See “— Antidilution Provisions” below.

Each share of Series C Preferred Stock automatically converts into shares of Common Stock at the conversion price at the time in effect immediately upon the Company’s sale of its Common Stock in a public offering provided that the offering price is not less than $16.50 per share (as adjusted for recapitalizations, stock combinations, stock dividends, stock splits and the like) and which results in aggregate cash proceeds of not less than $20.0 million before underwriting discounts, commissions, and fees. As of the date of this prospectus, no such sale has occurred.

Warrants

Investor Warrants

We issued the Investor Warrants in connection with various funding transactions or as consideration, in lieu of cash, for amounts billed in respect of services rendered to us. The Investor Warrants have terms ranging from five to ten years from the date of issuance. As of February 28, 2024, there were Investor Warrants to purchase 530,664 shares of Common Stock at exercise prices ranging from $0.17 to $8.25 per share.

Warrants issued in connection with the MSW Note

In September 2023, we issued warrants in lieu of a facility fee payment in connection with entering into the MSW Note with Matthews Southwest Holdings. These warrants have a five-year term from the date of issuance. As of February 28, 2024, there were 1,000,000 Existing MSW Warrants at an original exercise prices ranging from $1.00 to

Table of Contents

$1.50 per share. On November 16, 2023, we entered into a Warrant Amendment Agreement with Matthews Southwest Holdings, amending the Existing MSW Warrants to reduce the exercise price of an aggregate of 1,000,000 Existing MSW Warrants to $0.16 per share.

Warrants issued in connection with the 2021 Bridge Financing

We issued the Bridge Warrants to originally purchase 775,420 shares of Common Stock in connection with the 2021 Bridge Financing. The Bridge Warrants expire five years after the date of issuance, beginning on December 22, 2026, with an initial exercise price of $9.08 per share, subject to certain adjustments. No holder of a Bridge Warrant may exercise any portion of a Bridge Warrant if after giving effect to such exercise, such holder (together with its Attribution Parties) would beneficially own in excess of 4.99% of the number of shares of the Common Stock outstanding immediately after giving effect to the issuance of shares of Common Stock issuable upon exercise of such holder’s Bridge Warrant. This limitation may be waived by a holder, at its election, upon not less than 61 days’ prior notice to the Company, to change the limitation to 9.99% of the number of shares of the Common Stock outstanding immediately after giving effect to the issuance of shares of Common Stock upon exercise of such holder’s warrant. Any exercise of the Bridge Warrants resulting in a number of shares in excess of 9.99% of the number of shares of the Common Stock outstanding immediately after giving effect to the exercise shall be deemed null and void and shall be cancelled ab initio.

On September 8, 2022, we entered into an amendment to the Bridge Warrants, which we refer to as the Bridge Warrant Amendment No. 1. The Bridge Warrant Amendment No. 1 amended the Bridge Warrants by (i) increasing the number of shares of Common Stock for which the Bridge Warrants are exercisable from a total of 1,365,960 shares to a total of 1,683,470 shares, (ii) lowering the exercise price to $4.25 per share, (iii) providing that, until June 15, 2023, the exercise price will be further adjusted whenever the Company issues shares of Common Stock for consideration per share that when multiplied by 1.25 is less than the exercise price then in effect, subject to certain exceptions, (iv) confirming that, for purposes of the Bridge Warrants, the value of each share of Common Stock and each IPO Warrant was deemed to be $4.125 and $0.125, respectively, (v) providing that the number of shares of Common Stock underlying the Bridge Warrants will only be adjusted if the Company (a) pays a stock dividend on one or more classes of its then outstanding shares of Common Stock or otherwise makes a distribution on any class of capital stock that is payable in shares of Common Stock, (b) subdivides (by any stock split, stock dividend, recapitalization or otherwise) one or more classes of its then outstanding shares of Common Stock into a larger number of shares or (c) combines (by combination, reverse stock split or otherwise) one or more classes of its then outstanding shares of Common Stock into a smaller number of shares, and (vi) amending the formula for calculating Black Scholes values.

On February 3, 2023, we entered into a second amendment to the Bridge Warrants, which we refer to as the Bridge Warrant Amendment No. 2. The Bridge Warrant Amendment No. 2 amended the Bridge Warrants by (i) lowering the exercise price of $4.25 for the Limited Period, during which period the exercise price was set at $1.00, subject to adjustments set forth in the Bridge Warrant; (ii) providing that during the Limited Period, the holder was able, in its sole discretion, to elect a cashless exercise of the Bridge Warrant in whole or in part, pursuant to which the holder received a net number of shares of Common Stock equal to one-third of the total number of shares into which the Bridge Warrant could otherwise have been exercised; and (iii) removing the exercise price adjustment provisions of the Bridge Warrants with limited exceptions for transactions such as stock dividends, stock splits, stock combinations and reverse stock splits. Additionally, the Bridge Warrant Amendment No. 2 provided that in the event that the aggregate number of shares of Common Stock to be received by a holder upon an exercise of its Bridge Warrant during the Limited Period would result in such holder’s receiving shares of Common Stock in excess of its applicable Bridge Maximum Percentage, in lieu of delivery of shares of Common Stock in excess of the Bridge Maximum Percentage, the holder would receive such excess shares as pre-funded warrants substantially in the form of the Pre-Funded Bridge Warrants, with certain exercise price adjustment provisions removed. Further, the Bridge Warrant Amendment No. 2 included a waiver of Section 4(w) of the Bridge SPA, which placed certain restrictions on the Company’s ability to issue securities for a specified period of time.

During the Limited Period, Bridge Warrants were exercised for (i) a total of 1,172,304 shares of Common Stock at an exercise price of $1.00 per share or pursuant to cashless exercises in which the holder received a net number of shares of Common Stock equal to one-third of the total number of shares with respect to which the Bridge Warrant was exercised and (ii) the Remaining Pre-Funded Bridge Warrant to purchase 150,000 shares of Common Stock. At the end the Limited Period, Remaining Bridge Warrants to purchase a total of 298,667 shares of Common Stock remained outstanding, with the exercise price adjusted back to $4.25 per share, subject to future adjustments as set forth in the Remaining Bridge Warrants.

Table of Contents

The exercise price of the Remaining Bridge Warrants (as amended by the Bridge Warrant Amendment No. 1 and the Bridge Warrant Amendment No. 2) is subject to adjustment for certain events such as stock dividends, splits, and reverse splits or other combinations, but not otherwise as the result of issuances of additional securities by the Company, even if such issuances are at prices below the exercise price of the Bridge Warrants. Upon an adjustment of the exercise price as a result of a stock dividend, split, reverse split, combination or similar event, the number of shares of Common Stock to be received shall be proportionately adjusted. Otherwise, there are no antidilution provisions that result in adjustments to the number of shares of Common Stock to be received upon exercise of the Bridge Warrants.

All Pre-Funded Bridge Warrants that were issued upon conversion of the Bridge Notes have been exercised in full and are no longer outstanding as of the date of this prospectus, although the Remaining Pre-Funded Bridge Warrant issued in connection with Bridge Warrant Amendment No. 2 remains outstanding. For more information regarding the Bridge Warrants, please see “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Description of Indebtedness — 2021 Bridge Financing”.
