Company Overview

We are a medical technology company focused on applying innovative AIAI-based-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, particularly in frontline or point-of-care clinical settings.tool. HeartSciences’ first product candidate for FDA clearance, the MyoVista, wavECG, or the MyoVista, is a resting 1212-lead-lead ECG that iswill 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. In the future, we intend to incorporate additional AI-based algorithms in the MyoVista and develop a cloud-based platform to provide access to a range of AI-based ECG cardiovascular algorithms on an ECG hardware agnostic basis. The cardiac dysfunctionAI-based ECG algorithms provide diagnostic information related to structural heart disease which traditionally has only traditionally been available through the use of cardiac imaging. Our businessWe believe, the MyoVista is particularly well suited for a frontline or point of care clinical setting and the initial revenue model, which involves the use of the MyoVista devicehardware, associated software and consumables for each test, is expected to be “razor“razor-razorblade”-razorblade as the cable connection to the electrodes used with the MyoVista are proprietary to HeartSciences, and new electrodes are requiredused for every test performed. As of March 28,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.

On September 20, 2023, we had 12 full-time employees.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-based cardiovascular algorithms 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-based cardiovascular algorithms, two data science methods for use with ECG waveforms and three filed patents.

Our device is notNeither the MyoVista hardware, nor any of the AI-based ECG algorithms, are cleared for marketing by the FDA and our future success is dependent upon receiving FDA De Novo clearance for the MyoVista.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 or (“R&D.&D”).

We believe that there is currently no lowlow-cost,-cost front-line,, 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 thatthe test, called an ECG, helps physiciansdoctors predict heart risks in people with no symptoms any better than traditional considerations such as current or former smoking, blood pressure and cholesterol levels.levels in people with no symptoms.

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

HeartSciences has designed the MyoVistaor licensed algorithms to help address these limitations and extend the clinical capability of an ECG in detectingto detect cardiac dysfunction. We havedysfunction or specific cardiovascular disease types.

Table of Contents

The first AI algorithm to be incorporated into the MyoVista has been applying designed by the Company and applies AIAI-machine-machine learning to the signal processed electricalECG signal of the heart to develop a proprietary algorithm designed to detect cardiac dysfunction caused by heart disease and/or ageage-related-related cardiac dysfunction. We recently proposed adjustment of the echocardiographic measurement thresholds to the FDA to reflect recent clinical findings in respect of ≥ 60 year old patients which we believe will further increase the clinical value of the algorithm. The FDA has now confirmed this approach and 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 1212-lead-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 ageage-related-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 1212-lead-lead resting ECG could help improve cardiac referral pathways and be valuable for patients, physicians, health systems and third-partythird-party payors.

New Class II devices, such as the MyoVista, require FDA De Novo 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 are partwaypart-way through a new, pivotal clinical validation study and have been undertaking device and algorithm development and testing for a revised FDA submission. Our discussions to date with the FDA have been in relation to a revised submission under the De Novo submission, which we expect to take place during 2023.

We have beenpathway, however, in August 2023, the FDA granted an industry first De Novo clearance and created a new Class II product code for cardiovascular machine learning-based notification software in respect of a hypertrophic cardiomyopathy algorithm. In late September 2023, the FDA cleared an algorithm for low ejection fraction (less than 40%) under the 510(k) pathway using the net proceeds fromnew product code. Accordingly, we now believe it is probable that we could submit the IPOMyoVista algorithm for clearance under the 510(k) pathway. The 510(k) pathway is more common than De Novo and, intendon average, has a much quicker decision process than De Novo by the FDA. Accordingly, in October 2023, we submitted a pre-submission request to use proceedsthe FDA to, among other things, seek to confirm the appropriateness of a 510(k) submission.

Our independent registered public accounting firm has issued an opinion on our audited financial statements incorporated by reference into this prospectus that contains 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, limited capital resources, and a net stockholders’ deficit. These events and conditions indicate that a material uncertainty exists that may cast significant doubt on our ability to continue as a going concern. If we are unable to continue as a going concern, we may have to liquidate our assets, and the values we receive for our assets in liquidation or dissolution could be significantly lower than the values reflected in our financial statements.

Heart Disease Facts and Current ECG Testing Limitations

Heart disease refers to a variety of conditions that affect the heart—heart — including heart rhythm problems, heart valve problems, genetic defects and blood-vesselblood-vessel diseases such as CAD. It is often referred to as the “silent killer” and, accordingkiller.” 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 hadshowed no previous symptoms. Statistics published by the U.S. Centers for Disease Control and Prevention or CDC,(the “CDC”), show that in the United States heart disease is the leading cause of death for both men and women, and people ofacross most racial and ethnic groups. According to the CDC, in the United States, one person dies from cardiovascular disease every 36 seconds34 seconds. In 2020, about 20.1 million adults aged 20 and heart disease accounts forolder in the United States have CAD (about 7.2%), with approximately one in four deaths. In 2018, 30.3 million U.S. adults were diagnosed withfive heart disease including 18.2 million adults with CAD.attacks being a silent heart attack therefore the person is not even aware of it, but the damage is done. Approximately 605,000 patients697,000 people in the U.S. have adied from heart attack each year with approximately 20% of deaths from CAD occurringdisease in adults less than 65 years old.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. Ischemic heart disease now represents 16%Cardiovascular diseases are the leading cause of global deaths and andeath 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 costs incost the United States were approximately $363about $229 billion in each of 20162017 and 2017,2018, 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 lowlow-cost,-cost front-line,, 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-linefront-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-linecost-effective front-line or primary-care-basedprimary-care-based testing has resulted in the overover-use-use of costly cardiology-basedcardiology-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 or CMS.(“CMS”). There are a variety of effective, though expensive, diagnostic tests used for patients used 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, that 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.

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.

•        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;

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 or NIH,(“NIH”), state that approximately 50% of heart failure, or 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 or LVDD,(“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 ageage-related-related cardiac abnormalities that may otherwise be missed by current conventional ECG devices.

Product and Technology

The MyoVista deviceHeartSciences-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 1212-lead-lead resting ECG device that featuresfeaturing our proprietary algorithm developeddesigned to detect cardiac dysfunction in the diastolic phase, which is specifically slower than normal left ventricular relaxation rates, as defined byand incorporates 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-featuredfull-featured conventional 1212-lead-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 1212-lead-lead ECG Analysis Algorithm has been relied upon for more than 35 years and is a widely respectedused resting ECG interpretive algorithm. The Glasgow Algorithm has been improved over the years and is licensed to the Companyus pursuant to a licensing agreement with The University Court of the University of Glasgow, under whichGlasgow. Under this licensing agreement, we obtained a nonnon-exclusive,-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 1212-lead-lead electrocardiograms and (ii) all intellectual property rights (including patents, copyright, trademarks, trade secrets and knowknow-how)-how) relating to the software modules to be used in the MyoVista (the “Glasgow Licensing Agreement”). We are currently in discussions to amend this agreement.

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

Diagnostic Gap

We believe that the significant diagnostic gap in heart disease is early identification. Heart disease often remains asymptomatic for many years as disease progresses 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 biggestlargest cost for the USU.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-partythird-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 lowlow-cost-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 ageaged 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 CoCo-operation-operation and Development, advances in the field of medicine have led to an increase in life expectancy which, as of 2019,2020, was estimated to average 78.977.3. 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—Services — Office of the Inspector General or the HHS,(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 inby 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 ageaged 65 years and older, and that population pool is increasing, we believe there is a significant opportunity for a device such as the MyoVista.MyoVista as well as our AI-based 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-usedwidely used test throughout healthcare including nonnon-cardiology-cardiology settings. It is estimated that 1.5 million to 33.0 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 20182019 National Ambulatory Medical Care Survey indicated that office-basedoffice-based patient care physicians, excluding anesthesiologists, radiologists and federal facilities such as U.S. Department of Veterans Affairs clinics,pathologists, ordered or provided 2747 million ECG tests and four million stress ECGs during office visits, and the 20172020 National Hospital Ambulatory Medical Care Survey showed that during ambulatory care visits to hospital emergency departments, an additional 2832 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 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-riskhigh-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 prepre-symptomatic-symptomatic patients at risk more effectively at the front-linefront-line physician or clinic level and to treat recovering cardiac patients through outpatient care and rehabilitation.

It is our belief that the MyoVista isand our AI-based algorithms are positioned to respond to the global need for more effective, lowlow-cost-cost ECG testing that screens for 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 the MyoVista as a new medical deviceour AI-based algorithms that offersoffer an enhanced ability to screen for heart disease.

Capitation Provides an Incentive to Identify Medicare Advantage Patients

Healthcare providers are paid either through feefee-for-service-for-service or capitation. FeeFee-for-service-for-service is a payment model where services are unbundled and paid for separately. In health care, the feefee-for-service-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 42%48% (approximately 2628 million people) of those covered by Medicare according to CMS are enrolled in a Medicare Advantage plan. With respect to these patients, CMS pays capitation to healthcare providers. CMS uses risk adjustment to adjust capitation payments to health plans, either higher or lower, to account for the differences in the health costs of individuals with ailments such as heart failure, CAD, angina and valvular heart disease. Accordingly, under CMS guidelines, risk factor adjustments per patient will provide payment that is higher for sicker patients who have conditions where diagnosis codes are documented in the medical record as a result of a faceface-to-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 the MyoVista wavour AI-basedECG a algorithms widely available to significantly improve frontstandard-of-care,-line as an affordable and valuable medical test.testing for heart disease. Our business model which involves the capital sale of the MyoVista device, and the use ofincluding its proprietary supplies (electrodes) for each test, is as well as the revenue from the use of our AI“razor-razorblade.”-based algorithms. The algorithms are intended to be delivered either through the MyoVista hardware or through a cloud platform which will process electronic ECG files sent from non-MyoVista ECG devices to the cloud platform that contains the algorithms where the ECG records will be processed by HeartSciences algorithms and results returned to the physicians that ordered the tests. The electrode connection system of the MyoVista is patented which, together with our proprietary high quality-quality electrodes, facilitatefacilitates high quality, stable ECG signal capture, which, we believe is important as the MyoVista analyzes frequency data as well as conventional ECG information. Because newcapture. New electrodes are needed for each test, ourtest. Our proprietary electrodes, ifwhen purchased, would provide recurring perper-test-test revenue for each MyoVista device sold. In short, unlike many new healthcare products, we do not expect to primarily rely on high initial device pricing and instead will seek to encourage the adoption of the MyoVista when possible and intend to relyfocus on recurring revenue from electrode sales as an important aspectwell as use of our business model.HeartSciences’ AI-based algorithms.

Territories

Our initial sales focus will primarily be within the U.S. We intend to market the MyoVistaour 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 the MyoVista.AI-based 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 onprovided by the AI-based ECG algorithms such as cardiac dysfunction which the MyoVista is designed to provide, in addition to the conventional ECG information provided, could be extremely valuable.

The MyoVista’sOur AI-based algorithms range of applications and potential uses are vast, and include providing:

Primary care—front-line•        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.

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

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

Athlete testing—cardiac screening programs for athletes.

Early Target Markets

Initially, our focus markets will be on:include: cardiology; primary care providers that serve upper to middle income regions including concierge medicine providers; 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-based algorithm.

Reimbursement

In addition to targeting the health care settings described above, a key element of our strategy is to qualifyensure each algorithm qualifies for third-party payor reimbursement. This strategy has two stages. During the first stage, we intend to seek the support of the American College of Cardiology to use existing Current Procedural Terminology, or CPT, codes for the standard ECG functionality of the MyoVista.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. While we cannot assure you that we will receive such approval by ACC, this would provide physicians with the ability to use existing 12-lead ECG reimbursement codes. 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.

After this initial stage, our longer-term reimbursement strategy is to obtain additional reimbursement for the MyoVista capabilities related to detecting cardiac dysfunction. In July 2022, theThe American Medical Association has already issued new CPTa temporary Current Procedural Terminology (CPT) Category III codescode for novel AI assistive algorithmic ECG risk assessment for cardiac dysfunction. These codes are expected to cover the proprietary algorithm to be incorporated in the MyoVista. CPT Category III codes are designed to facilitate the use, adoption, and potential reimbursement of emerging technologies. The new codes went into effect inThis provides physicians and clinical institutions the CPT codebook on January 1, 2023.ability to bill for HeartSciences algorithms that detect different types of heart dysfunction such as systolic and diastolic dysfunction. While we cannot assure yoube 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 with a competitive advantage as compared to conventional ECG 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 the MyoVista.HeartSciences AI-based algorithms and MyoVista hardware. Competitors could include traditional ECG manufacturers such as General Electric Company, or GE Healthcare Technologies, Inc., (“GE Healthcare”), Koninklijke Philips N.V. (“Phillips”), Baxter International, Inc. (“Baxter”), and Nihon Kohden Corporation that may seek to innovate, due to competition from HeartSciences, and new competitorscommercial 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 finally innovatebring 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 technologythe intellectual property protection for our existing and any futurelicensed proprietary algorithms (especially when developing proprietary algorithms). We believe that the combination of patents and trade secrets createcreates 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 20292031 to August 2040. We also have fourteen international design registrations and eighteensixteen 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 and Australia. We currently have severalthree patent allowances in Europe, United Arab Emirates and Brazil and also have additional pending patent applications in multiple jurisdictions including India, Brazil, Europe and the United States.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 which we refer to as the MyoVista Technology Agreement, under which certain specified MyoVista technology and proprietary and intellectual property rights thereto (including patents, copyright, trademarks, trade secrets and knowknow-how)-how) were transferred and assigned to us by the inventor; and

•        In December 2015, we entered the Glasgow Licensing Agreement with The University Court of the University of Glasgow under which we obtained a nonnon-exclusive,-exclusive, worldwide license to software modules for an Android platform for analysis of resting 1212-lead-lead electrocardiograms and all intellectual property rights (including patents, copyright, trademarks, trade secrets and knowknow-how)-how) relating to the software modules to be used in the MyoVista. We are currently in discussions to amend this agreement.

Research and Development

The Company’s R&D staff designs our hardware, software and internally developed AIAI-based-based 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 elementssoftware of the software areMyoVista is designed by the Company along with the assistance of outside consultants. The data science work necessary to build the AIAI-based-based 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 four full-timefull-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-based 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-partythird-party published research in this field.

On December 1,November 29, 2022, we entered into a multi-yearmulti-year collaboration agreement with Rutgers, The State University of New Jersey, to develop additional AIAI-based-based ECG algorithms with our intention being to augment our product development pipeline for additional new ECG algorithms in the medium term .term. We believe that in the future the ECG will have significantly greater clinical value and will facilitate far more effective heart disease screening and referral.referral as these AI-based ECG algorithms obtain regulatory approval.

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-OxleySarbanes-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 nonnon-binding-binding advisory vote from our shareholders on executive compensation or golden parachute arrangements (commonly referred to as the “say“say-on-pay,-on-pay, “say-on-frequency“say-on-frequency” and “say“say-on-golden-parachute”-on-golden-parachute votes);

•        are exempt from certain executive compensation disclosure provisions requiring a paypay-for-performance-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 or (“MD&A;&A”); and

•        are eligible to claim longer phasephase-in-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 phasephase-in-in periods for the adoption of new or revised financial accounting standards under §107 of the JOBS Act. Our election to use the phasephase-in-in periods may make it difficult to compare our financial statements to those of nonnon-emerging-emerging growth companies and other emerging growth companies that have opted out of the phasephase-in-in periods under §107 of the JOBS Act. Please see “Risk Factors—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-describedabove-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 or the Securities Act,(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 nonnon-affiliates-affiliates (and are not otherwise eligible to be a smaller reporting company), or issue more than $1 billion in principal amount of nonnon-convertible-convertible debt over a three-yearthree-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 nonnon-affiliates)-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 paypay-for-performance-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 nonnon-affiliates-affiliates is less than $250 million as of the last business day of theour second fiscal quarter or (ii) our annual revenue was less than $100 million during theour most recently completed fiscal year and the market value of our stock held by nonnon-affiliates-affiliates is less than $700 million as of the last business day of theour 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 ReportReports on Form 1010-K-K and, similar to emerging growth companies, smaller reporting companies have reduced disclosure obligations regarding executive compensation.

Compliance with Nasdaq Listing Requirements

On December 21, 2022, we received notice from the Listing Qualifications Staff (“Staff”) of The Nasdaq Stock Market LLC or Nasdaq,(“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 1010-Q-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 February 3, 2023, we submitted a plan to Nasdaq to regain compliance with the Minimum Stockholders’ Equity Requirement. On February 8, 2023, Nasdaq notified us that they have granted us an extension of up to 180 calendar days from December 21, 2022, i.e., through June 19, 2023, to regain compliance. IfOn June 20, 2023, we failreceived a delist determination letter from Nasdaq advising us that Nasdaq determined that we did not meet the terms of the extension by the June 19, 2023 deadline.

On June 27, 2023, we submitted a hearing request to evidence compliancethe Nasdaq Hearing Panel (the “Panel”) to appeal the delisting determination. In response to our request for a hearing, on June 27, 2023, we received a letter from Nasdaq stating that its delisting action has been stayed, pending a final decision by the Panel and a hearing will be held on August 17, 2023.

On August 2, 2023, we received a letter from the Staff indicating that, based upon filing our annual report for the year ending April 30, 2023 with the SEC and Nasdaq,closing bid price of our Common Stock and IPO Warrantsfor 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 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 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.

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 oneone-third-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 prepre-funded-funded warrants substantially in the form of the PrePre-Funded-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, the Companywe issued 1,172,304 shares of Common Stock and a prepre-funded-funded warrant to purchase 150,000 shares of Common Stock (the “Remaining PrePre-Funded-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 thea Purchase Agreement (the “Lincoln Park Purchase Agreement”) with Lincoln Park Capital Fund, LLC (“Lincoln Park”) pursuant to which we have the right, but not the obligation, to sell to Lincoln Park up to $15,000,000 of Purchase Shares from time to time over the a 3636-month-month term beginning only after certain conditions set forth in the Lincoln Park Purchase Agreement have been satisfied, including that thisthe registration statement registering the Purchase Shares for resale (the “Lincoln Park Registration StatementStatement”) shall have been declared effective under the Securities Act, which we refer to as the Commencement Date. 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 shares of our Common Stockthe Purchase Shares under the Lincoln Park Purchase Agreement. At the time Lincoln Park’s purchases cumulatively reach 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.

Under applicable rules of Nasdaq, in no event may we issue or sell to Lincoln Park under the Lincoln Park Purchase Agreement shares of our Common Stock, including the Commitment Shares, in excess of 1,927,022 shares, which is equal to 19.99% of the shares of our Common Stock outstanding immediately prior to the execution of the Lincoln Park Purchase Agreement (the “Exchange Cap”) unless (i) we obtain shareholder approval to issue shares of our Common Stock in excess of the Exchange Cap or (ii) the average price of all shares of Common Stock issued to Lincoln Park under the Lincoln Park Purchase Agreement equals or exceeds $1.16 per share (which represents the official closing price of our Common Stock on The Nasdaq Capital Market the day of signing of the Lincoln Park Purchase Agreement), such that the transactions contemplated by the Lincoln Park Purchase Agreement are exempt from the Exchange Cap limitation under applicable Nasdaq rules. In any event, the Lincoln Park Purchase Agreement specifically provides that we may not issue or sell any shares of our Common Stock under the Lincoln Park Purchase Agreement if such issuance or sale would breach any applicable rules or regulations of the Nasdaq. 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 (as calculated pursuant to Section 13(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and Rule 13d13d-3-3 thereunder), would result in Lincoln Park and its affiliates beneficially owning more than 9.99% of the then total outstanding shares of Common Stock, which we refer to herein as 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 shares of our Common StockPurchase Shares and Commitment Shares that have been and may be issued to Lincoln Park under the Lincoln Park Purchase Agreement pursuant to thisthe 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 October 10, 2023, we have issued 1,219,930 shares to Lincoln Park, including the Initial Commitment Shares, receiving gross proceeds of approximately $1.0 million.

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-based 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-based 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-based 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. Our anticipated commercialization efforts will initially focus on achieving FDA clearance and European CE Mark regulatory approval.

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

19

Table of Contents

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 actually 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-based 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.

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.

RISK FACTORS

Investing in our Common Stocksecurities involves a high degree of risk. You should consider carefully the risks and uncertainties described below, together with all of the other information incorporated by reference intoincluded in this prospectus as well as the risk factors included in Item 1A. “Risk Factors” in our Annual Report on Form 1010-K-K for the year ended April30, 20222023 incorporated by reference into this prospectus, before making a decision to invest in our Securities. 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 of the following risks actually occur, our business, platform, reputation, brand, results of operations, financial condition and prospects could be materially and adversely affected. In such event, the market price of our Securities could decline, and you could lose all or part of your investment.

Risks Related to Our Financial Condition and Capital Requirements

There is substantial doubt about our ability to continue as a going concern.

Our independent registered public accounting firm has issued an opinion on our audited financial statements incorporated by reference into this Offeringregistration statement that contains 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 indicate that a material uncertainty exists that may cast significant doubt on our ability to continue as a going concern. The perception that we may not be able to continue as a going concern may have a material adverse effect on our share price and our ability to raise new capital (whether it is through the issuance of equity or debt securities or otherwise), enter into critical contractual relations with third parties and otherwise execute our business objectives. Until we can generate significant recurring revenues, we expect to satisfy our future cash needs through debt or equity financing. We cannot be certain that additional funding will be available to us on acceptable terms, if at all. Our financial statements do not include any adjustments that may result from the outcome of this uncertainty.

If we are unable to continue as a going concern, we may have to liquidate our assets, and the Ownership ofvalues we receive for our Common Stockassets in liquidation or dissolution could be significantly lower than the values reflected in our financial statements.

We have been notified by The Nasdaq Stock Market LLC of our failure to comply with certain continued listing requirements and, if we are unable to regain compliance with all applicable continued listing requirements and standards of Nasdaq, our Common Stock could be delisted from Nasdaq.

Our Common Stock and IPO Warrants are currently listed on Nasdaq. In order to maintain that listing, we must satisfy minimum financial and other continued listing requirements and standards, including those regarding director independence and independent committee requirements, minimum stockholders’ equity, minimum share price, and certain corporate governance requirements.

On December 21, 2022, we received notice from the Listing Qualifications Staff of Nasdaq indicating that we were not in compliance with the Minimum Stockholders’ Equity Requirement, because our stockholders’ equity of $1,082,676 as reported in our Quarterly Report on Form 1010-Q-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 February 3, 2023, we submitted to Nasdaq a plan to regain compliance with the Minimum Stockholders’ Equity Requirement. On February 8, 2023, Nasdaq notified us that they have granted us an extension of up to 180 calendar days from December 21, 2022, or through June 19, 2023, to regain compliance. IfOn June 20, 2023, we failreceived a delist determination letter from Nasdaq advising us that Nasdaq determined that we did not meet the terms of the extension by the June 19, 2023 deadline.

On June 27, 2023, we submitted a hearing request to evidence compliancethe Panel to appeal the delisting determination. In response to our request for a hearing, on June 27, 2023, we received a letter from Nasdaq stating that its delisting action has been stayed, pending a final decision by the Panel and a hearing will be held on August 17, 2023.

Table of Contents

On August 2, 2023, we received a letter from the Staff of Nasdaq indicating that, based upon filingthe closing bid price of our periodic reportCommon Stock for the year ending Aprillast 30 2023consecutive business days, we no longer met the requirement to maintain the Minimum Bid Price Requirement. In accordance with Nasdaq listing rules, we have until January 29, 2024 to regain compliance with the SEC and Nasdaq,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 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.

The Company attended an August 17, 2023 hearing before the Panel, and requested the continued listing of its securities on the Nasdaq Capital Market pending its return to compliance with the Minimum Stockholder’s Equity Requirement and Minimum Bid Price Requirement.

On August 28, 2023, the Company received a decision from the Panel granting the Company’s request for continued listing on the Nasdaq Capital Market, subject to delisting. If Nasdaq determinesthe Company demonstrating compliance with the Minimum Stockholders’ Equity Requirement on or before November 21, 2023, and certain other conditions. In addition, the Company has until January 29, 2024, to delist our Common Stock, we will havedemonstrate compliance with the right to appeal to a Nasdaq hearings panel.Minimum Bid Price Requirement.

There can be no assurances that we will be able to regain compliance with the Minimum Stockholders’ Equity Requirement and the Minimum Bid Price Requirement, or if we do regain compliance with the Minimum Stockholders’ Equity Requirement and the Minimum Bid Price Requirement, that we will be able to continue to comply with all applicable Nasdaq listing requirements in the future. If we are unable to maintain compliance with these Nasdaq requirements, our Common Stock and IPO Warrants will be delisted from Nasdaq.

In the event that our Common Stock isand IPO Warrants are delisted from Nasdaq, as a result of our failure to comply with the Minimum Stockholders’ Equity Requirement or the Minimum Bid Price Requirement, or due to our failure to continue to comply with any other requirement for continued listing on Nasdaq, and is not eligible for listing on another exchange, trading in the shares of our Common Stock could be conducted in the overover-the-counter-the-counter market or on an electronic bulletin board established for unlisted securities such as the Pink Sheets or the OTC Bulletin Board. In such event, it could become more difficult to dispose of, or obtain accurate price quotations for, our Common Stock, and it would likely be more difficult to obtain coverage by securities analysts and the news media, which could cause

the price of our Common Stock to decline further. Also, it may be difficult for us to raise additional capital if we are not listed on a national exchange.

Although our Common Stock began trading on The Nasdaq Stock Market LLC on June 15, 2022, we do not know whether an active, liquid trading market for our Common Stock will be sustained or whatRisks Related to the trading priceOwnership of our Common Stock will be in the future. Our Securities and this Offering

Our Common Stock may trade at a price below the price you paid and may be difficult for you to sell the Common Stock you purchase.

Although our Common Stock is listed on The Nasdaq and began trading on June 15, 2022,Stock Market LLC, or Nasdaq, an active trading market for our Common Stock may not be achieved or sustained. It may be difficult for you to sell your Common Stock without depressing the market price for the Common Stock or at all. Consequently, you may not be able to sell your Common Stock at or above the price you paid, or at all. Further, an inactive market may also impair our ability to raise capital by selling additional shares of Common Stock and it also may impair our ability to enter into strategic partnerships or acquire companies, products, or services by using our equity securities as consideration.

Prior to the IPO, there was not a public trading market for shares of our Common Stock. We cannot predict the extent to which investor interest in us will sustainlead to the development of an active trading market or how active and liquid that market may become in the future.become. If an active and liquid trading market does not develop or continue, you may have difficulty selling your Common Stock at an attractive price or at all. The initial public offering price per share of Common Stock in the IPO was determined by agreement between us and the representative of the underwriters and may not be indicative of the price at which shares of our Common Stock will trade in the public market in the future. The market price of our Common Stock may decline below the price you paid, and you may not be able to sell your Common Stock at or above the price you paid, or at all.

The market price of our Common Stock has been and may continue to be highly volatile, and you could lose all or part of your investment.

Since our IPO the highest and lowest price of our Common Stock has been $6.00 and $0.30, respectively. The market price of our Common Stock is likely to continue to be volatile, which may prevent you from being able to sell your Common Stock at or above the price you paid for your shares. This volatility could be the result of a variety of factors, which include:

•        whether we achieve our anticipated corporate objectives;

•        actual or anticipated fluctuations in our quarterly or annual operating results;

•        changes in our financial or operational estimates or projections;

•        our ability to implement our operational plans;

•        termination of locklock-up-up agreements or other restrictions on the ability of our shareholders to sell shares after the IPO;shares;

•        changes in the economic performance or market valuations of companies similar to ours;

•        general economic or political conditions in the U.S. or elsewhere; and

•        other events or factors, including those resulting from war, incidents of terrorism or responses to these events.

In addition, the stock market in general, and the stock of publicly-tradedpublicly-traded medical device companies in particular, have experienced extreme price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of such companies. Broad market and industry factors may negatively affect the market price of our Common Stock, regardless of our actual operating performance, and we have little or no control over these factors.

Since our management will have broad discretion in how we use the proceeds from this offering, we may use the proceeds in ways with which you disagree.

Our management will have broad discretion over the use of proceeds from this offering. We intend to use the net proceeds from this offering for any of the purposes described in the section of this prospectus entitled “Use of Proceeds.” Our management will have considerable discretion in the application of the net proceeds, and you will not have the opportunity, as part of your investment decision, to assess whether the proceeds are being used appropriately. The net proceeds may be used for corporate purposes that do not improve our operating results or enhance the value of the shares of our Common Stock. The failure of our management to use these funds effectively could have a material adverse effect on our business, cause the market price of the shares of our Common Stock to decline and impair the commercialization of our products and/or delay the development of our product candidates. Pending their use, we may invest the net proceeds from this offering in short-term, investment-grade, interest-bearing instruments and U.S. government securities. These investments may not yield a favorable return to our stockholders.

This is a best efforts offering, no minimum amount of Securities is required to be sold, and we may not raise the amount of capital we believe is required for our business plans.

The placement agent has agreed to use its reasonable best efforts to solicit offers to purchase the Securities being offered in this offering. The placement agent has no obligation to buy any of the Securities from us or to arrange for the purchase or sale of any specific number or dollar amount of the Securities. There is no required minimum number of Securities or amount of proceeds that must be sold as a condition to completion of this offering. Because there is no minimum offering amount required as a condition to the closing of this offering, the actual offering amount, placement agent fees and proceeds to us are not presently determinable and may be substantially less than the maximum amounts set forth above. We may sell fewer than all of the securities offered hereby, which may significantly reduce the amount of proceeds received by us, and investors in this offering will not receive a refund in the event that we do not sell an amount of securities sufficient to fund for our operations as described in the “Use of Proceeds” section herein. Thus, we may not raise the amount of capital we believe is required for our operations in the short term and may need to raise additional funds, which may not be available or available on terms acceptable to us.

If you purchase our securities being sold in this offering, you will experience immediate and substantial dilution in the net tangible book value of your shares. In addition, we may issue additional equity or convertible debt securities in the future, which may result in additional dilution to investors.

The price per share of our Common Stock being offered in this offering may be higher than the net tangible book value per share of the outstanding shares of our Common Stock prior to this offering. Assuming the sale of all Securities offered hereby, based on an assumed public offering price of $0.42 per share, the closing sale price of our Common Stock on the Nasdaq Capital Market on October 10, 2023, for aggregate net proceeds of approximately $7.1 million, and after deducting commissions and estimated offering expenses payable by us, new investors in this offering will incur immediate dilution of $0.16 per share. For a more detailed discussion of the foregoing, see the section entitled “Dilution” below. To the extent outstanding preferred stock or convertible notes are converted or outstanding stock options or warrants (including placement agent warrants) are exercised, there will be further dilution to new investors.

Future sales of a substantial number of shares of our Common Stock by our existing shareholders in addition to the shares offered by this prospectus could cause our stock price to decline.

As of March 23,October 10, 2023, there were 9,739,93110,970,980 shares of our Common Stock outstanding. In addition, as of March 23,October 10, 2023 there were 375,671380,440 shares of Series C Preferred Stock outstanding that, as of such date, were convertible into 1,636,646 shares of Common Stock, a convertible note which could convert into 5,200 shares of Series C Preferred Stock (which could then convert into 22,654 shares of Common Stock), and warrants (including the Bridge Warrants) and options exercisable for 4,368,785 shares of our Common Stock. All of the1,865,452 shares of Common Stock and IPO Warrants sold in the IPO became eligibleoptions and warrants exercisable for sale immediately upon issuance in the IPO.5,426,210 shares of our Common Stock. Additional shares will be eligible for sale in the public market upon expiration of the remaining unexpired locklock-up-up agreements entered into in connection with the IPO. Subject to any applicable locklock-up-up agreements, pursuant to Rule 144 under the Securities Act as in effect on the date hereof, or Rule 144, a person who holds restricted shares of Common Stock (assuming there are any restricted shares) and is not one of our affiliates at any time during the three months preceding a sale, and who has beneficially owned these restricted shares for at least six months, would be entitled to sell an unlimited number of shares of our Common Stock, provided current public information about us is available. In addition, under Rule 144, a person who holds restricted shares in us and is not one of our affiliates at any time during the three months preceding a sale, and who has beneficially owned these restricted shares for at least one year, would be entitled to sell an unlimited number of shares without regard to whether current public information about us is available. It is conceivable that following the holding period, many shareholders may wish to sell some or all of their shares. If our shareholders or the holder of our placement agent warrants upon the exercise of such warrants sell substantial amounts of our Common Stock in the public market at the same time, the market price of our Common Stock could decrease significantly due to an imbalance in the supply and demand of our Common Stock. Even if they do not actually sell the Common Stock, the perception in the public market that our shareholders or the holder of our placement agent warrants upon the exercise of such warrants might sell significant Common Stock could also depress the market price of our Common Stock.

If securities or industry analysts do not publish or cease publishing research or reports about us, our business or our market, or if they publish negative reports regarding our business or our securities, our share price and trading volume could decline.

The trading market for the Common Stock will be influenced by the research and reports that industry or securities analysts may publish about us, our business, our market or our competitors. We do not have any control over these analysts and we cannot provide any assurance that analysts will cover us or provide favorable coverage. If any of the analysts who may cover us adversely change their recommendation regarding the Common Stock, or provide more favorable relative recommendations about our competitors, the price of our Common Stock would likely decline. If any analyst who may cover us were to cease coverage of our Company or fail to regularly publish reports on us, we could lose visibility in the financial markets, which in turn could cause the price of our Common Stock or trading volume to decline.

Management has broad discretion as to the use of proceeds we may receive from the sale of Purchase Shares to Lincoln Park.

Our management has broad discretion in the allocation of proceeds we may receive from the sale of Purchase Shares to Lincoln Park and could use such proceeds for purposes other than those contemplated at the date of this prospectus. Our shareholders may not agree with the manner in which our management chooses to allocate and spend such proceeds.

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

Although the proceeds of the sale of shares of our Common Stock to Lincoln Park, if any, and the net proceeds from our IPO and the sale of Purchase Shares to Lincoln Parkthis offering are anticipated to be sufficient to achieve FDA clearance, which would allow us to market the MyoVista in the U.S.,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 Purchase Sharesshares to Lincoln Park in order to support the sales launch of the MyoVista into the U.S., provide working capital and support further

Table of Contents

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. 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.

We have identified weaknesses in our internal controls, and we cannot provide assurances that these weaknesses will be effectively remediated or that additional material weaknesses will not occur in the future.

Prior to the completion of the IPO, we had been a private company with limited accounting personnel to adequately execute our accounting processes and limited supervisory resources with which to address our internal control over financial reporting. While a private company, we had not designed or maintained an effective control environment as required of public companies under the rules and regulations of the SEC. Management and our independent registered public accounting firm, Haskell & White LLP, identified several material weaknesses in our internal control over financial reporting in connection with our preparation and the audits of our financial statements for Fiscal 20222023 and Fiscal 2021.2022.

A material weakness is a deficiency, or combination of deficiencies, in internal control over financing reporting such that there is a reasonable possibility that a material misstatement of our annual or interim financial statements will not be prevented or detected on a timely basis. The material weaknesses we and our independent registered public accounting firms identified are listed below:

•        lack of proper approval processes and review of processes and documentation for such reviews;

•        we did not maintain sufficient U.S. GAAP and SEC accounting resources commensurate with those required of a public company; and

we had an •        insufficient number of staff to maintain optimal segregation of duties and levels of oversight; andoversight.

we did not have strong accounting consideration and analysis over equity accounts and inventory valuation.

These material weaknesses resulted in adjustments to our prior year financial statements primarily related to equity accounts, accruals, and inventory and could result in a misstatement of any account balances or disclosures that would result in a material misstatement to the annual or interim financial statements that would not be prevented or detected.

We have taken and continue to take remedial steps to improve our internal controls over financial reporting, which includes hiring additional accounting and financial reporting personalpersonnel and implementing additional policies, procedures, and controls. We cannot assure you that these measures will significantly improve or remediate the material weaknesses described above. Management is monitoring the effectiveness of these and other processes, procedures and controls and will make any further changes deemed appropriate. Management believes the foregoing actions will effectively remediate the material weaknesses, however, our material weaknesses will not be considered remediated until controls are in place for a period of time, the controls are tested, and management concludes that the controls are properly designed and operating effectively. As a result, the timing of when we will be able to fully remediate the material weaknesses is uncertain. If the steps we take

do not remediate the material weaknesses in a timely manner, there could continue to be a reasonable possibility that these control deficiencies or others would result in a material misstatement of our annual or interim consolidated financial statements that would not be prevented or detected on a timely basis. This, in turn, could jeopardize our ability to comply with our reporting obligations, limit our ability to access the capital markets and adversely impact our stock price.

Our independent registered public accounting firm was not required to perform an evaluation of our internal control over financial reporting as of either April 30, 20222023 or April 30, 20212022 in accordance with the provisions of the Sarbanes-OxleySarbanes-Oxley Act. Accordingly, we cannot assure you that we have identified all, or that we will not in the future

Table of Contents

have additional, material weaknesses. Material weaknesses may still exist when we report on the effectiveness of our internal control over financial reporting in the future as required by reporting requirements under Section 404 of the Sarbanes-OxleySarbanes-Oxley Act.

If we are unable to successfully remediate the existing material weaknesses in our internal control over financial reporting, the accuracy and timing of our financial reporting, and our stock price, may be adversely affected and we may be unable to maintain compliance with the applicable stock exchange listing requirements. Implementing any appropriate changes to our internal controls may divert the attention of our officers and employees, entail substantial costs to modify our existing processes and take significant time to complete. These changes may not, however, be effective in maintaining the adequacy of our internal controls, and any failure to maintain that adequacy, or consequent inability to produce accurate financial statements on a timely basis, could increase our operating costs and harm our business. In addition, investors’ perceptions that our internal controls are adequate or that we are unable to produce accurate financial statements on a timely basis may harm our stock price and make it more difficult for us to effectively market and sell our services to new and existing customers.

Our Board of Directors is authorized to issue and designate shares of our preferred stock in additional series without shareholder approval.

Our amended and restated certificate of formation as amended (“Certificate(the “Certificate of Formation”), authorizes our Board of Directors, without the approval of our shareholders, to issue shares of our preferred stock, subject to limitations prescribed by applicable law, rules and regulations and the provisions of our Certificate of Formation, as shares of preferred stock in series, to establish from time to time the number of shares to be included in each such series and to fix the designation, powers, preferences, privileges and rights of the shares of each such series and the qualifications, limitations or restrictions thereof. The powers, preferences and rights of these additional series of preferred stock may be senior to or on parity with our Common Stock, which may reduce its value.

As of March 23,October10, 2023, our principal shareholders, officers and directors beneficially owned approximately 26.7%26.2% of our Common Stock. They will therefore be able to exert significant control over matters submitted to our shareholders for approval.

As of March 23,October 10, 2023, our principal shareholders, officers and directors beneficially owned approximately 26.7%26.2% of the outstanding shares of our Common Stock. Immediately following the completion of this offering and the assumed closing of the Mount Sinai Transaction, our principal shareholders (which shall thereafter include Mount Sinai), officers and directors will beneficially own approximately 17.8% of the outstanding shares of our Common Stock (assuming the sale of all shares of Common Stock offered hereby, at an assumed public offering price of $0.42 per share, the closing sale price of our Common Stock on the Nasdaq Capital Market on October 10, 2023), including shares issuable pursuant to antidilution provisions set forth in the Series C Preferred Stock. This significant concentration of share ownership may adversely affect the trading price for our Common Stock because investors often perceive disadvantages in owning shares in companies with controlling shareholders. As a result, these shareholders, if they acted together, could significantly influence or even unilaterally approve matters requiring approval by our shareholders, including the election of directors and the approval of mergers or other business combination transactions. The interests of these shareholders may not always coincide with our interests or the interests of other shareholders. For more information regarding the beneficial ownership of such principal shareholders, officers and directors, see “Security Ownership of Certain Beneficial Owners and Management and Related Shareholder Matters.”

Provisions of the IPO Warrants and the Remaining Bridge Warrants could discourage an acquisition of us by a third party.

In addition to the provisions of our Certificate of Formation and second amended and restated bylaws (“Bylaws”), certain provisions of the IPO Warrants and the Remaining Bridge Warrants could make it more difficult or

expensive for a third party to acquire us. The IPO Warrants and the Remaining Bridge Warrants prohibit us from engaging in certain transactions constituting “fundamental transactions” unless, among other things, the surviving entity assumes our obligations under the IPO Warrants and the Remaining Bridge Warrants. These and other provisions of the IPO Warrants and the Remaining Bridge Warrants could prevent or deter a third party from acquiring us even where the acquisition could be beneficial to you.

We have incurred and will continue to incur significant costs as a result of the listing of our securities for trading on Nasdaq. As a public company in the U.S., our management is required to devote substantial time to new compliance initiatives as well as compliance with ongoing U.S. requirements.

Upon the listing of securities on Nasdaq, we became a publicly traded company in the United States and as such, we are incurring significant accounting, legal and other expenses that we did not incur before the IPO. We also are incurring costs associated with corporate governance requirements of the SEC, as well as requirements under Section 404 and other provisions of the Sarbanes-OxleySarbanes-Oxley Act. We expect these rules and regulations to continue to increase our legal and financial compliance costs, introduce new costs such as investor relations, stock exchange listing fees and shareholder reporting, and to make some activities more time consuming and costly. The implementation and testing of such processes and systems may require us to hire outside consultants and incur other significant costs. Any future changes in the laws and regulations affecting public companies in the United States,

including Section 404 and other provisions of the Sarbanes-OxleySarbanes-Oxley Act, and the rules and regulations adopted by the SEC, for so long as they apply to us, will result in increased costs to us as we respond to such changes. These laws, rules and regulations could make it more difficult or more costly for us to obtain certain types of insurance, including director and officer liability insurance, and we may be forced to accept reduced policy limits and coverage or incur substantially higher costs to obtain the same or similar coverage. The impact of these requirements could also make it more difficult for us to attract and retain qualified personspeople to serve on our Board of Directors, any committees of our Board of Directors, or as executive officers.

We may be subject to securities litigation, which is expensive and could divert management attention.

In the past, companies that have experienced volatility in the market price of their stock have been subject to securities class action litigation. We may be the target of this type of litigation in the future. Litigation of this type could result in substantial costs and diversion of management’s attention and resources, which could seriously hurt our business. Any adverse determination in litigation could also subject us to significant liabilities.

We have never paid cash dividends on our Common Stock, and we do not anticipate paying any cash dividends in the foreseeable future.

We have neither declared nor paid cash dividends, and we do not anticipate paying cash dividends in the foreseeable future. Therefore, you should not rely on an investment in Common Stock as a source for any future dividend income. Our Board of Directors has complete discretion as to when or whether to distribute dividends. Even if our Board of Directors decides to declare and pay dividends, the timing, amount and form of future dividends, if any, will depend on our future results of operations and cash flow, our capital requirements and surplus, the amount of distributions, if any, received by us from our subsidiaries, our financial condition, contractual restrictions and other factors deemed relevant by our Board of Directors.

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.

We are an “emerging growth company” as defined in the JOBS Act, and, for as long as we continue to be an emerging growth company, we may choose to take advantage of exemptions from various reporting requirements applicable to other public companies including, but not limited to, not being required to comply with the auditor

attestation requirements of Section 404 of the Sarbanes-OxleySarbanes-Oxley Act, not being required to comply with any new requirements adopted by the Public Company Accounting Oversight Board, or the PCAOB, requiring mandatory audit firm rotation or a supplement to the auditor’s report in which the auditor would be required to provide additional information about the audit and the financial statements of the issuer, not being required to comply with any new audit rules adopted by the PCAOB after April 5, 2012 unless the SEC determines otherwise, reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved. We could remain an emerging growth company until the earlier of: (i) the last day of the fiscal year in which we have total annual gross revenues of $1.235 billion or more; (ii) the last day of our fiscal year following the fifth anniversary of the date of our first sale of common equity securities pursuant to an effective registration statement; (iii) the date on which we have issued more than $1.0 billion in nonconvertible debt during the previous three years; or (iv) the date on which we are deemed to be a large accelerated filer. We cannot predict if investors will find our Common Stock less attractive if we choose to rely on these exemptions. If some investors find our Common Stock less attractive as a result of any choices to reduce future disclosure, there may be a less active trading market for our Common Stock and our stock price may be more volatile. Further, as a result of these scaled regulatory requirements, our disclosure may be more limited than that of other public companies and you may not have the same protections afforded to shareholders of such companies.

Section 107 of the JOBS Act also provides that an emerging growth company can take advantage of the extended transition period provided in Section 7(a)(2)(B) of the Securities Act, for complying with new or revised accounting standards. We have opted for takingto take advantage of the extended transition period for complying with new or revised accounting standards pursuant to Section 107(b) of the Jobs Act.

Anti-takeoverAnti-takeover provisions could make a third party-party acquisition of us difficult.

This provision could make it more difficult for a third party to acquire us without the approval of our Board of Directors.board. In addition, the Texas Business Organizations Code, (“TBOC”)or the TBOC, also contains certain provisions that could make an acquisition by a third party-party more difficult.

Provisions of the IPO Warrants, the Remaining Bridge Warrants and our Series C Preferred Stock could discourage an acquisition of us by a third party.

In addition to the provisions of our Certificate of Formation and Bylaws, certain provisions of the IPO Warrants, the Remaining Bridge Warrants and the Series C Preferred Stock could make it more difficult or expensive for a third party to acquire us. The terms of the IPO Warrants, the Remaining Bridge Warrants and the

Table of Contents

Series C Preferred Stock prohibit us from engaging in certain transactions constituting “fundamental transactions” or a “Deemed Liquidation Event”, unless, among other things, the surviving entity assumes our obligations under the IPO Warrants, the Remaining Bridge Warrants or the Series C Preferred Stock. These and other provisions of the IPO Warrants, the Remaining Bridge Warrants or the Series C Preferred Stock could prevent or deter a third party from acquiring us even where the acquisition could be beneficial to you.

Financial Industry Regulatory Authority, Inc. (“FINRA”) sales practice requirements may limit a stockholder’s ability to buy and sell our shares Common Stock.

FINRA has adopted rules that require that in recommending an investment to a customer, a broker-dealer must have reasonable grounds for believing that the investment is suitable for that customer. Prior to recommending speculative low-priced securities to their non-institutional customers, broker-dealers must make reasonable efforts to obtain information about the customer’s financial status, tax status, investment objectives and other information. Under interpretations of these rules, FINRA believes that there is a high probability that speculative low-priced securities will not be suitable for certain customers. FINRA requirements will likely make it more difficult for broker-dealers to recommend that their customers buy our shares of Common Stock, which may have the effect of reducing the level of trading activity in our Common Stock. As a result, fewer broker-dealers may be willing to make a market in our Common Stock, reducing a stockholder’s ability to resell shares of our Common Stock.

If our shares of Common Stock become subject to the penny stock rules, it would become more difficult to trade our shares.shares of Common Stock.

The SEC has adopted rules that regulate broker-dealerbroker-dealer practices in connection with transactions in penny stocks. Penny stocks are generally equity securities with a price of less than $5.00, other than securities registered on certain national securities exchanges or authorized for quotation on certain automated quotation systems, provided that current price and volume information with respect to transactions in such securities is provided by the exchange or system. If we do not retain a listing on Nasdaq and if the price of our shares of Common Stock is less than $5.00, our shares of Common Stock will be deemed a penny stock. The penny stock rules require a broker-dealer,broker-dealer, before a transaction in a penny stock not otherwise exempt from those rules, to deliver a standardized risk disclosure document containing specified information. In addition, the penny stock rules require that before effecting any transaction in a penny stock not otherwise exempt from those rules, a broker-dealerbroker-dealer must make a special written determination that the penny stock is a suitable investment for the purchaser and receive (i) the purchaser’s written acknowledgment of the receipt of a risk disclosure statement; (ii) a written agreement to transactions involving penny stocks; and (iii) a signed and dated copy of a written suitability statement. These disclosure requirements may have the effect of reducing the trading activity in the secondary market for our shares of Common Stock, and therefore shareholders may have difficulty selling their shares of Common Stock.

Risks Related to Our License Agreements with Mount Sinai

We may not ultimately receive anythe Licenses from Mount Sinai since the issuance of the Licenses is subject to the Company raising at least $5,000,000 in gross proceeds from one or more financings prior to December 31, 2023, and further, at least $10,000,000 in gross proceeds from one or more financings raised prior to June 30, 2024.

The issuance of the saleLicenses from Mount Sinai is subject to a condition which mandates that we raise a minimum of $5,000,000 in gross proceeds from a financing or a series of financings between the period of August 1, 2023 and prior to December 31, 2023. Moreover, even if the $5,000,000 threshold is met, we must raise an aggregate of $10,000,000 prior to June 30, 2024 (inclusive of the $5,000,000), otherwise Mount Sinai may terminate the

31

Table of Contents

License Agreements. Failure to meet one or both of the financing thresholds within the stipulated time frames may result in the denial of the Licenses being issued and termination of our License Agreements with Mount Sinai. This condition presents a significant risk to our business, as our ability to meet the fundraising target may be influenced by various factors, including market conditions, investor sentiment, and economic uncertainties. If we are unable to secure the necessary capital within the specified timeframe, we may be unable to obtain the Licenses, which could materially impact our ability to operate and generate revenue, potentially leading to a loss of business opportunities and financial harm to our company and shareholders.

As a result of the Mount Sinai Transaction, our shareholders will suffer immediate and substantial dilution.

Because of the issuance of shares of Common Stock, common stock warrants and pre-funded warrants to Mount Sinai, our stockholders may experience significant dilution of their ownership interests. Furthermore, if the License Agreements are terminated by Lincoln ParkMount Sinai after we have satisfied the Financing Requirement but ultimately fail to meet the Additional Financing Requirement, Mount Sinai will have the right to retain the securities issued or issuable to them under the Securities Purchase Agreement at its own discretion, which represent 15% of the then-issued and outstanding shares of our Common Stock. For a further description of the dilution that investors in this offering.offering will experience, see “Dilution.”

We are highly dependent on the Licenses, the termination of which may prevent us from commercializing our products, and which imposes significant obligations on us.

We are highly dependent on the intellectual property licensed from Mount Sinai, pursuant to which we aim to incorporate the licensed technology for use and development in our MyoVista products. Other products or services we may develop also may rely on the same technology. In the event that we fail to use no less than commercially reasonable efforts to develop and commercialize the licensed products in their respective field of use as soon as reasonably practicable, and we do not cure such breach within the applicable time period, Mount Sinai could terminate the Licenses. Any termination of the Licenses resulting in the loss of the licensed rights would prevent us from marketing and selling our anticipated MyoVista products and any other products or services we may develop based on such underlying licensed technology. Any termination of the exclusivity of the license, in those cases where applicable, could damage our competitive position within the marketplace.

Furthermore, the License Agreements impose significant obligations on us. We will be required to pay Mount Sinai royalties in low-single digit percentages of annual net sales of licensed products sold by the Company and a share of any sublicense revenue received by the Company from sublicensees of the licensed products as well as achieve the milestones prescribed by the License Agreements and Securities Purchase Agreement.

Our future financial performance will depend in part on the successful integration, improvement and software updates from the Mount Sinai algorithms.

Our future financial performance will depend in part on our ability to influence, anticipate, identify and respond to changing consumer preferences and needs and the technologies relating to the care and treatment of heart disease. We can provide no assurances that the Mount Sinai algorithms and products will be successfully integrated, achieve significant commercial success and gain meaningful market share. We may receive upnot correctly anticipate or identify trends in consumer preferences or needs or may identify them later than competitors do. In addition, difficulties in manufacturing or in obtaining regulatory approvals due to $15,000,000integrating the Mount Sinai algorithms or providing a cloud-based environment to host the algorithms may delay or prohibit our algorithm-based product offerings from completing the development process. Further, we may not be able to develop improvements and software updates to our “EKG” product at a cost that allows us to meet our goals for profitability. Service costs relating to our product may be greater than anticipated and we may be required to devote significant resources to address any quality issues associated with our product.

Failure to successfully introduce, improve or update our products on a cost-effective basis, or delays in aggregate gross proceeds under the Purchase Agreement from any sales we make to Lincoln Park from time to time pursuantcustomer decisions related to the Purchase Agreement afterevaluation of our products could cause us to lose market acceptance and could materially adversely affect our business, financial condition and results of operations.

Our future success depends on our ability to develop, receive regulatory clearance or approval for, and introduce the datealgorithms underlying the Mount Sinai Licenses to the market in a timely manner. If we do not obtain and maintain the regulatory registrations and clearances for the algorithms, we will be unable to market and sell the MyoVista utilizing the Licenses in the United States, Europe or other regions.

In the United States, before we can market a new medical device, or a new use of, new claim for or significant modification to, an existing product, we must first receive either approval of a Premarket Approval Application, or PMA, clearance under Section 510(k), or be granted a De Novo classification, in accordance with the Federal Food, Drug, and Cosmetic Act, or the FDCA. For additional information on the PMA or the De Novo classification processes, see “Business — FDA and Other Government Regulation.”

The FDA can delay, limit or deny clearance or approval of a medical device for many reasons, including:

•        we may not be able to demonstrate to the FDA’s satisfaction that the algorithms underlying the Mount Sinai Licenses are safe and effective for its intended use;

•        the data from our pre-clinical studies and clinical trials may be insufficient to support clearance or approval, where required; and

•        the manufacturing process or facilities we use or contract to use may not meet applicable requirements.

Sales of our device outside of the United States and the EEA are also subject to foreign regulatory requirements that vary widely from country to country. Approval procedures vary among countries and can involve additional testing. Complying with foreign regulatory requirements, including obtaining registrations, clearances or approvals, can be expensive and time-consuming, and we may not receive regulatory clearances or approvals in each country in which we plan to market our device, or we may be unable to do so on a timely basis. If we modify our device, we may need to apply for additional regulatory clearances or approvals before we are permitted to sell the modified device. In addition, we may not continue to meet the quality and safety standards required to maintain the authorizations that we have received. If we are unable to maintain our authorizations in a particular country, we will no longer be able to sell the applicable device in that country.

Regulatory clearance or approval by the FDA does not ensure registration, statementclearance or approval by regulatory authorities in other countries, and registration, clearance or approval by one or more foreign regulatory authorities does not ensure registration, clearance or approval by regulatory authorities in other foreign countries or by the FDA. However, a failure or delay in obtaining registration or regulatory clearance or approval in one country may have a negative effect on the regulatory process in others.

We estimate that the net proceeds to us from the sale of sharesthe Securities offered in this offering will be approximately $7.1 million (assuming the sale of all Securities offered hereby, based on an assumed public offering price of $0.42 per share, the closing sale price of our Common Stock to Lincoln Park pursuanton the Nasdaq Capital Market on October 10, 2023, and after deducting placement agent fees and estimated offering expenses payable by us). However, because this is a best efforts offering and there is no minimum offering amount required as a condition to the Purchase Agreement will be upclosing of this offering, the actual offering amount, the placement agent’s fees and net proceeds to $15,000,000 over an approximately 36-month period, assuming that such salesus are not limited bypresently determinable and may be substantially less than the Exchange Cap andmaximum amounts set forth on the cover page of this prospectus. In addition, we sellmay receive proceeds from the full amount of Common Stock that we have the right, but not the obligation, to sell to Lincoln Park under the Purchase Agreement, and before other estimated fees and expenses. We may sell fewer than allexercise of the shares permitted to be sold pursuantplacement agent warrants, to the Purchase Agreement, in which case our offeringextent such placement agent warrants are exercised for cash, but we will not receive any proceeds will be less. Because we are not obligated to issue or sellfrom any sale of the shares of our Common Stock underunderlying the Purchase Agreement, other than the Initial Commitment Shares (from which we will receive no proceeds), 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 Purchase Agreement.

As of the date of this prospectus, we cannot predict with certainty all the uses for the net proceeds if any, we may receive fromto be received upon the salecompletion of Purchase Shares to Lincoln Park under the Purchase Agreement.this offering. We currently intend to use suchthe net proceeds if any, in conjunction with the remaining proceeds from our IPO and proceeds received from the cash exercises of Bridge Warrants, (i)this offering for costs directly related to achievingobtaining FDA clearance for the MyoVista device including costsand our AI-based ECG algorithms, for relevant Company personnel, associated device testing, validation and R&D, and completing the pivotal clinical validation study, (ii) for working capital and general corporate purposes until we can obtain FDA approval, (iii) to pay accrued and unpaid interest to one lender (John Q. Adams, Sr., a former director of the Company) under the $1M Loan and Security Agreement on or before September 30, 2023, which is estimated to be $77,000 as of such date, and (iv) with respect to the remainder, if any, for working capital and general corporate purposes, including personnel costs, capital expenditures, interest and debt repayments and the costs of operating as a public company. The promissory note issued to John Q. Adams, Sr. pursuant toOur debt that may be repaid from the $1M Loan and Security Agreement, as amended through the datenet proceeds of this prospectus (the “Adams Note”), matures on March 31, 2024 and the promissory issuedoffering consists of up to Front Range Ventures, LLC, or FRV, pursuant to the $1M Loan and Security Agreement, as amended through the datea maximum of this prospectus (the “FRV Note”), matures on September 30, 2024. At January 31, 2023, the aggregate principal balance outstanding under the Adams Note and the FRV Note was $1.0 million and the interest rate under each promissory note was 12% per annum. FRV is a beneficial owner of more than five percent (5%) of the combined voting power of our outstanding capital stock and Mr. Adams is a former director of the Company.

We received approximately $5.2 million in net proceeds from our IPO after deducting the underwriting discount and commission and other IPO expenses payable by the Company of approximately $1.2 million. As of March 23, 2023, we had used approximately $4.6 million of the loan evidenced by the MSW Note, which repayment amount will depend on the actual amount of our drawdown under such loan. As of October 10, 2023, we have drawn approximately $0.5 million under the MSW Note, which note bears no interest, matures on December 31, 2023 and may be repaid at any time in whole or in part without fees or penalty. We have not allocated specific amounts of net proceeds from the IPO.for any of these purposes.

Changing circumstances may cause us to consume capital significantly faster than we currently anticipate. The amounts and timing of our actual expenditures will depend upon numerous factors, including the progress of our global marketing and sales efforts, our development efforts and the overall economic environment.

Therefore, our management will retain broad discretion over the use of the proceeds from this offering. We may ultimately use the proceeds for different purposes than what we currently intend. Pending any ultimate use of any portion of the proceeds from this offering, if the anticipated proceeds will not be sufficient to fund all the proposed purposes, our management will determine the order of priority for using the proceeds, as well as the amount and sources of other funds needed.

We believe that the funds raised in this offering will be sufficient to finance the purposes described above, and we do not think that material amounts of other funds will be necessary to finance such purposes.

MARKET PRICE AND DIVIDENDS ON COMMON EQUITY AND RELATED SHAREHOLDER MATTERSPending our use of the net proceeds from this offering, we may invest the net proceeds in a variety of capital preservation investments, including short-term, investment grade, interest bearing instruments and U.S. government securities.

DIVIDEND POLICY

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.

Registration Rights

We previously granted certain registration rights to the holders of the Series C Preferred Stock. Under the terms of thisthe registration rights agreement, which we refer to as the Series C Registration Rights Agreement, the holders of the Series C Preferred Stock owning not less than 30% of (i) the Common Stock issuable or issued upon conversion of the Series C Preferred Stock; and (ii) any Common Stock issued as (or issuable upon the conversion or exercise of any warrant, right, or other security that is issued as) a dividend or other distribution with respect to, or in exchange for or in replacement of, the shares referenced in clause (i) above, referred to herein as the Series C Registrable Securities, and the anticipated aggregate offering price, net of certain expenses, would exceed $10 million, may demand that the Companywe file a registration statement relating to the Series C Registrable Securities owned by the holders who have demanded such registration. In addition, if at any time when it iswe are eligible to use a Form S-3registration statement the Company receiveson Form S-3, we receive a request from holders of at least twenty-fivetwenty-five percent (25%) of the Series C Registrable Securities then outstanding that the Companywe file a Form S-3registration statement on Form S-3 with respect to outstanding Series C Registrable Securities of such holders having an anticipated aggregate offering price, net of certain expenses, of at least $3 million, then the Company

we will be required to file a registration statement relating to the resale of the Series C Registrable Securities owned by such holders. Finally, if the Company proposeswe propose to register (including, for this purpose, a registration effected by the Companyus for shareholders other than the holders of the Series C Preferred Stock) any of the Common Stock under the Securities Act in connection with the public offering of such securities solely for cash, the Company iswe are required to give each holder of Series C Registrable Securities notice of such registration and such holders may include their Series C Registrable Securities in such registration statement.

Anti-takeover Effects of Certain Provisions of Our Certificate of Formation, Bylaws and Texas Law

Our Certificate of Formation and Bylaws and the TBOC contain provisions, which are summarized in the following paragraphs, thatwhich are intended to enhance the likelihood of continuity and stability in the composition of our Board of Directors. These provisions are intended to avoid costly takeover battles, reduce our vulnerability to a hostile change of control and enhance the ability of our Board of Directors to maximize shareholder value in connection with any unsolicited offer to acquire us. However, these provisions may have an anti-takeoveranti-takeover effect and may delay, deter or prevent a merger or acquisition of the Company by means of a tender offer, a proxy contest or other takeover attempt that a shareholder might consider in its best interest, including those attempts that might result in a premium over the prevailing market price for the shares of Common Stock held by shareholders.

Authorized but unissued capital stock

Texas law does not require shareholder approval for any issuance of authorized shares. However, the listing requirements of the Nasdaq, which apply so long as our securities are listed on the Nasdaq, require shareholder approval of certain issuances equal to or exceeding 20% of the then outstanding voting power or then outstanding number of shares of Common Stock. Additional shares that may be issued in the future may be used for a variety of corporate purposes, including future public offerings, to raise additional capital or to facilitate acquisitions.

Our Board of Directors may generally issue shares of Preferred Stock on terms calculated to discourage, delay or prevent a change of control of the Company or the removal of our management. Moreover, our authorized but unissued shares of Preferred Stock are available for future issuances without shareholder approval and could be utilized for a variety of corporate purposes, including future offerings to raise additional capital, to facilitate acquisitions and employee benefit plans.

One of the effects of the existence of unissued and unreserved shares of Common Stock or Preferred Stock may be to enable our Board of Directors to issue shares to persons friendly to current management, which issuance could render more difficult or discourage an attempt to obtain control of the Company by means of a merger, tender offer, proxy contest or otherwise, and thereby protect the continuity of our management and possibly deprive our shareholders of opportunities to sell their shares of Common Stock at prices higher than prevailing market prices.

Table of Contents

Classified Board of Directors

Our Certificate of Formation provides that our Board of Directors be divided into three classes of directors, with the classes to be as nearly equal in number as possible, and with the directors serving three-yearthree-year terms. As a result, approximately oneone-third-third of our Board of Directors will be elected each year. The classification of directors will have the effect of making it more difficult for shareholders to change the composition of our Board of Directors. Our Certificate of Formation and Bylaws provide that, subject to any rights of holders of Preferred Stock to elect additional directors under specified circumstances, the number of directors will be fixed from time to time exclusively pursuant to a resolution adopted by the Board of Directors.

Removal of directors; vacancies

Under the TBOC, unless otherwise provided in our Certificate of Formation, directors serving on a classified board may be removed by the shareholders only for cause. Our Certificate of Formation provides that

directors may be removed only for cause. In addition, our Certificate of Formation also provides that, subject to the rights granted to one or more series of Preferred Stock then outstanding, any vacancy occurring in our Board of Directors may be filled by election at an annual or special meeting of the shareholders called for that purpose or by the affirmative vote of a majority of the directors then in office (even if the remaining directors constitute less than a quorum of the Board of Directors), and any director so chosen shall hold office for the remainder of the term to which the director has been selected and until such director’s successor shall have been elected and qualified.

No cumulative voting

Under Texas law, the right to vote cumulatively does not exist unless the certificate of formation specifically authorizes cumulative voting. Our Certificate of Formation does not authorize cumulative voting. Therefore, shareholders holding a majority in voting power of the shares of our stock entitled to vote generally in the election of directors will be able to elect all our directors.

Special shareholder meetings

Our Certificate of Formation provides that special meetings of our shareholders may be called at any time by the Board of Directors, the chairman of the Board of Directors or the chief executive officer of the Company. Our Bylaws prohibit the conduct of any business at a special meeting other than as specified in the notice for such meeting. These provisions may have the effect of deferring, delaying or discouraging hostile takeovers, or changes in control or management of the Company.

Requirements for advance notification of director nominations and shareholder proposals

Our Bylaws establish advance notice procedures with respect to shareholder proposals and the nomination of for election as directors, other than nominations made by or at the direction of the Board of Directors or a committee of the Board of Directors. In order for any matter to be “properly brought” before a meeting, a shareholder will have to comply with advance notice requirements and provide us with certain information. Generally, to be timely, a shareholder’s notice must be received at our principal executive offices not less than 75 days nor more than 100 days prior to the first anniversary date of the immediately preceding annual meeting of shareholders. Our Bylaws also specify requirements as to the form and content of a shareholder’s notice. Our Bylaws allow the chairman of the meeting at a meeting of the shareholders to adopt rules and regulations for the conduct of meetings which may have the effect of precluding the conduct of certain business at a meeting if the rules and regulations are not followed. These provisions may also defer, delay or discourage a potential acquiror from conducting a solicitation of proxies to elect the acquiror’s own slate of directors or otherwise attempting to influence or obtain control of the Company.

Shareholder action by written consent

Our Certificate of Formation provides that any action required or permitted to be taken at an annual or special meeting of shareholders may be taken by written consent in lieu of a meeting of shareholders only with the unanimous written consent of our shareholders.

Table of Contents

Amendment and restatement of Bylawsbylaws

Our Bylaws provide that the Board of Directors is expressly authorized to make, alter, amend, change, add to, rescind or repeal, in whole or in part, our Bylaws without a shareholder vote in any matter not inconsistent with the laws of the State of Texas and our Certificate of Formation.

The combination of the classification of our Board of Directors and the lack of cumulative voting will make it more difficult for shareholders to replace our Board of Directors as well as for another party to obtain control of us by replacing our Board of Directors. Because our Board of Directors has the power to retain and discharge our officers, these provisions could also make it more difficult for existing shareholders or another party to effect a change in management.

These provisions may have the effect of deterring hostile takeovers or delaying or preventing changes in control of our management or the Company, such as a merger, reorganization or tender offer. These provisions are intended to enhance the likelihood of continued stability in the composition of our Board of Directors and its policies and to discourage certain types of transactions that may involve an actual or threatened acquisition of the Company. These provisions are designed to reduce our vulnerability to an unsolicited acquisition proposal. The provisions are also intended to discourage certain tactics that may be used in proxy fights. However, such provisions could have the effect of discouraging others from making tender offers for our shares and, as a consequence, they also may inhibit fluctuations in the market price of our shares that could result from actual or rumored takeover attempts. Such provisions may also have the effect of preventing changes in management.

Dissenters’ rights of appraisal and payment

Under the TBOC, with certain exceptions, our shareholders will have appraisal rights in connection with a merger, a sale of all or substantially all of our assets, an interest exchange or a conversion. Pursuant to the TBOC, shareholders who properly request and perfect appraisal rights in connection with such merger, sale of all or substantially all of our assets, interest exchange or conversion will have the right to receive payment of the fair value of their shares as agreed to between the shareholder and the Company or, if they are unable to reach agreement, as determined by the State District Court in Tarrant County, Texas.

Shareholders’ derivative actions

Under the TBOC, any of our shareholders may bring an action in our name to procure a judgment in our favor, also known as a derivative action, provided that the shareholder bringing the action (i) is a holder of our shares at the time of the transaction to which the action relates or such shareholder became a shareholder by operation of law from a person that was a shareholder at the time of the transaction to which the action relates and (ii) fairly and adequately represents the interests of the Company in enforcing the right of the Company.

Limitations on liability and indemnification of officers and directors

The TBOC authorizes corporations to limit or eliminate the personal liability of directors to corporations and their shareholders for monetary damages for breaches of directors’ fiduciary duties (other than breaches of the directors’ duty of loyalty to corporations or their shareholders), subject to certain exceptions. Our Certificate of Formation includes a provision that limits the personal liability of directors for monetary damages for an act or omission in the director’s capacity as a director to the fullest extent permitted by Texas law. However, exculpation will not apply to any director if the director has acted in bad faith, engaged in intentional misconduct, knowingly violated the law, authorized illegal dividends or redemptions, derived an improper benefit from his or her actions as a director or engaged in an act or omission for which the liability of the director is expressly provided by an applicable statute.

Our Certificate of Formation provides that we must indemnify our directors and officers to the fullest extent authorized by the TBOC. We also are expressly authorized to carry directors’ and officers’ liability insurance providing indemnification for our directors, officers and certain employees for some liabilities. We believe that these indemnification provisions and insurance will be useful to attract and retain qualified directors and officers.

57

Table of Contents

The limitation of liability and indemnification provisions in our Certificate of Formation and Bylaws may discourage shareholders from bringing a lawsuit against directors for breach of their fiduciary duty. These provisions also may have the effect of reducing the likelihood of derivative litigation against directors and officers, even though such an action, if successful, might otherwise benefit us and our shareholders. In addition, your investment may be adversely affected to the extent we pay the costs of settlement and damage awards against directors and officers pursuant to these indemnification provisions. As of the date of this prospectus,July 21, 2023, there is no pending material litigation or proceeding involving any of our directors, officers or employees for which indemnification is sought.

Business combinations

Under Title 2, Chapter 21, Subchapter M of the TBOC, we may not engage in certain “business combinations” with any “affiliated shareholder,” or any affiliate or associate of the affiliated shareholder for a three-yearthree-year period following the time that the shareholder became an affiliated shareholder, unless:

•        prior to such time, our Board of Directors approved either the business combination or the transaction which resulted in the shareholder becoming an affiliated shareholder; or

•        not less than six months after the affiliated shareholders’ share acquisition date, the business combination is approved by the affirmative vote at a meeting, and not by written consent, of holders of at least 662/3% of our outstanding voting shares that are not owned by the affiliated shareholder or an affiliate or associate of the affiliated shareholder.

Generally, a “business combination” includes a merger, asset or stock sale or other similar transaction. Subject to certain exceptions, an “affiliated shareholder” is a person who beneficially owns (as determined pursuant to Title 2, Chapter 21, Subchapter M of the TBOC), or within the previous three years beneficially owned, 20% or more of our outstanding voting shares. For purposes of this section only, “voting share” has the meaning given to it in Title 2, Chapter 21, Subchapter M of the TBOC.

Under certain circumstances, this provision will make it more difficult for a person who would be an “affiliated shareholder” to effect various business combinations with the Company for a three-yearthree-year period. This provision may encourage companies interested in acquiring the Company to negotiate in advance with our Board of Directors because the shareholder approval requirement would be avoided if our Board of Directors approves either the business combination or the transaction that results in such shareholder becoming an affiliated shareholder. These provisions also may have the effect of preventing changes in our Board of Directors and may make it more difficult to accomplish transactions which shareholders may otherwise deem to be in their best interests.

MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES TO HOLDERS OF COMMON STOCK

The following is available and complied with.

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

Lincoln Park has informed us that it intends to use an unaffiliated broker-dealer to effectuate all sales, if any,material U.S. federal income tax consequences of the acquisition, ownership and disposition of the shares of Common Stock (which we sometimes refer to as our “securities” and holders thereof as “holders”), but does not purport to be a complete analysis of all the potential tax considerations relating thereto. This summary is based upon the provisions of the Internal Revenue Code of 1986, as amended (the “Code”), Treasury Regulations promulgated thereunder, administrative rulings and judicial decisions, all as of the date hereof. These authorities may be changed or subject to differing interpretations, possibly with retroactive effect, so as to result in U.S. federal income tax consequences different from those set forth below. We have not sought and will not seek any ruling from the U.S. Internal Revenue Service (the “IRS”) with respect to the statements made and the conclusions reached in the following summary, and there can be no assurance that the IRS or a court will agree with such statements and conclusions.

This summary also does not address the tax considerations arising under the laws of any U.S. state or local or any non-U.S. jurisdiction, estate or gift tax, the 3.8% Medicare tax on net investment income or any alternative minimum tax consequences. In addition, this discussion does not address tax considerations applicable to a holder’s particular circumstances or to a holder that may be subject to special tax rules, including, without limitation:

•        banks, insurance companies or other financial institutions;

•        tax-exempt or government organizations;

•        brokers or dealers in securities or currencies;

•        traders in securities that elect to use a mark-to-market method of accounting for their securities holdings;

•        persons that own, or are deemed to own, more than five percent of our capital stock;

•        certain U.S. expatriates, citizens or former long-term residents of the United States;

•        persons who hold our shares of Common Stock or Warrants as a position in a hedging transaction, “straddle,” “conversion transaction,” synthetic security, other integrated investment, or other risk reduction transaction;

•        persons who do not hold our Common Stock or Warrants as a capital asset within the meaning of Section 1221 of the Code (generally, for investment purposes);

•        persons deemed to sell our Common Stock or Warrants under the constructive sale provisions of the Code;

•        pension plans;

•        partnerships, or other entities or arrangements treated as partnerships for U.S. federal income tax purposes, or investors in any such entities;

•        persons for whom our stock constitutes “qualified small business stock” within the meaning of Section 1202 of the Code;

•        integral parts or controlled entities of foreign sovereigns;

•        controlled foreign corporations;

•        passive foreign investment companies and corporations that accumulate earnings to avoid U.S. federal income tax; or

•        persons that acquire our Common Stock or Warrants as compensation for services.

Table of Contents

In addition, if a partnership, including any entity or arrangement classified as a partnership for U.S. federal income tax purposes, holds our securities, the tax treatment of a partner generally will depend on the status of the partner, the activities of the partnership, and certain determinations made at the partner level. Accordingly, partnerships that hold our securities, and partners in such partnerships, should consult their tax advisors regarding the U.S. federal income tax consequences to them of the purchase, ownership, and disposition of our securities.

You are urged to consult your tax advisor with respect to the application of the U.S. federal income tax laws to your particular situation, as well as any tax consequences of the purchase, ownership and disposition of our securities arising under the U.S. federal estate or gift tax rules or under the laws of any U.S. state or local or any non-U.S. or other taxing jurisdiction or under any applicable tax treaty.

Definition of a U.S. Holder

For purposes of this summary, a “U.S. Holder” is any beneficial owner of our securities that is a “U.S. person,” and is not a partnership, or an entity treated as a partnership or disregarded from its owner, each for U.S. federal income tax purposes. A U.S. person is any person that, for U.S. federal income tax purposes, is or is treated as any of the following: (a) a citizen or individual resident of the United States, (b) a corporation (or other entity or arrangement treated as a corporation for U.S. federal income tax purposes) created in, or organized under the laws of, the United States or any state thereof or the District of Columbia, (c) an estate whose income is subject to United States federal income tax regardless of its source, or (d) a trust (i) the administration of which is subject to the primary supervision of a U.S. court and which has one or more United States persons (within the meaning of Section 7701(a)(30) of the Code) who have the authority to control all substantial decisions of the trust or (ii) that has otherwise elected to be treated as a United States person under the Code.

For purposes of this summary, a “Non-U.S. Holder” is any beneficial owner of our securities that is not a U.S. Holder or a partnership, or other entity treated as a partnership or disregarded from its owner, each for U.S. federal income tax purposes.

Tax Consequences to U.S. Holders

Distributions on Common Stock

As discussed above under “Dividend Policy,” we do not currently expect to make distributions on our Common Stock. In the event that we do make distributions of cash or other property, distributions paid on Common Stock, other than certain pro rata distributions of Common Stock, will be treated as a dividend to the extent paid out of our current or accumulated earnings and profits and will be includible in income by the U.S. Holder and taxable as ordinary income when received. If a distribution exceeds our current and accumulated earnings and profits, the excess will be first treated as a tax-free return of the U.S. Holder’s investment, up to the U.S. Holder’s tax basis in the Common Stock. Any remaining excess will be treated as a capital gain. Subject to applicable limitations, dividends paid to certain non-corporate U.S. Holders may be eligible for taxation as “qualified dividend income” and therefore may be taxable at rates applicable to long-term capital gains. U.S. Holders should consult their tax advisers regarding the availability of the reduced tax rate on dividends in their particular circumstances. Dividends received by a corporate U.S. Holder will be eligible for the dividends-received deduction if the U.S. Holder meets certain holding period and other applicable requirements.

Sale or Other Disposition of Common Stock

For U.S. federal income tax purposes, gain or loss realized on the sale or other disposition of Common Stock will be capital gain or loss, and will be long-term capital gain or loss if the U.S. Holder held the Common Stock for more than one year. The amount of the gain or loss will equal the difference between the U.S. Holder’s tax basis in the Common Stock disposed of and the amount realized on the disposition. Long-term capital gains recognized by non-corporate U.S. Holders will be subject to reduced tax rates. The deductibility of capital losses is subject to limitations.

FOR NON-U.S. HOLDERS

The following is a general discussion of the material U.S. federal income tax considerations applicable to non-U.S. holders (as defined herein) with respect to their ownership and disposition of our securities issued pursuant to this offering. All prospective non-U.S. holders of our securities should consult their tax advisors with respect to the U.S. federal, state, local and non-U.S. tax consequences of the purchase, ownership and disposition of our securities. In general, a non-U.S. holder means a beneficial owner of our Common Stock (other than a partnership or an entity or arrangement treated as a partnership for U.S. federal income tax purposes) that is not, for U.S. federal income tax purposes:

•        an individual who is a citizen or resident of the United States;

•        a corporation, or an entity treated as a corporation for U.S. federal income tax purposes, created or organized in the United States or under the laws of the United States or of any state thereof or the District of Columbia;

•        an estate, the income of which is subject to U.S. federal income tax regardless of its source; or

•        a trust if (1) a U.S. court can exercise primary supervision over the trust’s administration and one or more U.S. persons have the authority to control all of the trust’s substantial decisions or (2) the trust has a valid election in effect under applicable U.S. Treasury Regulations to be treated as a U.S. person.

This discussion is based on current provisions of the Code, existing U.S. Treasury Regulations promulgated thereunder, published administrative pronouncements and rulings of the IRS and judicial decisions, all as in effect as of the date of this prospectus. These authorities are subject to change and to differing interpretation, possibly with retroactive effect. Any change or differing interpretation could alter the tax consequences to non-U.S. holders described in this prospectus.

We assume in this discussion that a non-U.S. holder holds shares of our securities as a capital asset within the meaning of Section 1221 of the Code (generally, for investment). This discussion does not address all aspects of U.S. federal income taxation that may be relevant to a particular non-U.S. holder in light of that non-U.S. holder’s individual circumstances, nor does it address any alternative minimum, Medicare contribution, estate or gift tax consequences, or any aspects of U.S. state, local or non-U.S. taxes. This discussion also does not consider any specific facts or circumstances that may purchase from usapply to a non-U.S. holder and does not address the special tax rules applicable to particular non-U.S. holders, such as holders that own, or are deemed to own, more than 5% of our capital stock (except to the extent specifically set forth below), corporations that accumulate earnings to avoid U.S. federal income tax, tax-exempt organizations, banks, financial institutions, insurance companies, brokers, dealers or traders in securities, commodities or currencies, tax-qualified retirement plans, holders who hold or receive our Common Stock pursuant to the Purchase Agreement.exercise of employee stock options or otherwise as compensation, holders holding our Common Stock as part of a hedge, straddle or other risk reduction strategy, conversion transaction or other integrated investment, holders deemed to sell our Common Stock under the constructive sale provisions of the Code, controlled foreign corporations, passive foreign investment companies and certain former U.S. citizens or former long-term residents.

In addition, this discussion does not address the tax treatment of partnerships (or entities or arrangements that are treated as partnerships for U.S. federal income tax purposes) or persons that hold our securities through such partnerships. If a partnership, including any entity or arrangement treated as a partnership for U.S. federal income tax purposes, holds our securities, the U.S. federal income tax treatment of a partner in such partnership will generally depend upon the status of the partner and the activities of the partnership. Such salespartners and partnerships should consult their tax advisors regarding the tax consequences of the purchase, ownership and disposition of our securities.

There can be no assurance that a court or the IRS will not challenge one or more of the tax consequences described herein, and we have not obtained, nor do we intend to obtain, a ruling with respect to the U.S. federal income tax consequences to a non-U.S. holder of the purchase, ownership or disposition of our securities.

Distributions

As discussed in the section entitled “Dividend Policy,” we do not anticipate paying any dividends on our Common Stock in the foreseeable future. If we make distributions on our Common Stock or on the Warrants (as described above under “Constructive Dividends on Warrants”), those payments will constitute dividends for U.S. federal income tax purposes to the extent we have current or accumulated earnings and profits, as determined under U.S. federal income tax principles. To the extent those distributions exceed both our current and our accumulated earnings and profits, they will constitute a return of capital and will first reduce a Non-U.S. Holder’s basis in our Common Stock or the Warrants, as applicable, but not below zero. Any excess will be made at pricestreated as capital gain and at terms then prevailingwill be treated as described below under “Gain on Sale or at prices relatedOther Disposition of Common Stock or Warrants.” Any such distributions would be subject to the then current market price. Eachdiscussions below regarding back-up withholding and the Foreign Account Tax Compliance Act, or FATCA.

Subject to the discussion below on effectively connected income, any dividend paid to a Non-U.S. Holder generally will be subject to U.S. withholding tax either at a rate of 30% of the gross amount of the dividend or such unaffiliated broker-dealerlower rate as may be specified by an applicable income tax treaty. To receive a reduced treaty rate, a Non-U.S. Holder must provide us or our agent with an IRS Form W-8BEN, IRS Form W-8 BEN-E or another appropriate version of IRS Form W-8 (or a successor form), which must be updated periodically, and which, in each case, must certify qualification for the reduced rate. Non-U.S. Holders should consult their tax advisors regarding their entitlement to benefits under any applicable income tax treaty.

Dividends paid to a Non-U.S. Holder that are effectively connected with the Non-U.S. Holder’s conduct of a trade or business within the United States and that are not eligible for relief from U.S. (net basis) income tax under an applicable income tax treaty generally are exempt from the (gross basis) withholding tax described above. To obtain this exemption from withholding tax, the Non-U.S. Holder must provide the applicable withholding agent with an IRS Form W-8ECI or successor form or other applicable IRS Form W-8 certifying that the dividends are effectively connected with the Non-U.S. Holder’s conduct of a trade or business within the United States. Such effectively connected dividends, if not eligible for relief under a tax treaty, would not be subject to a withholding tax, but would be taxed at the same graduated rates applicable to U.S. persons, net of certain deductions and credits and if, in addition, the Non-U.S. Holder is a corporation, may also be subject to a branch profits tax at a rate of 30% (or such lower rate as may be specified by an applicable income tax treaty).

If you are eligible for a reduced rate of withholding tax pursuant to a tax treaty, you may be able to obtain a refund of any excess amounts withheld if you timely file an appropriate claim for refund with the IRS.

Backup Withholding and Information Reporting

Information returns may be filed with the IRS in connection with distributions on our Common Stock or constructive dividends on the Warrants, and the proceeds of a sale or other disposition of the Common Stock or the Warrants. A non-exempt U.S. Holder may be subject to U.S. backup withholding on these payments if it fails to provide its taxpayer identification number to the withholding agent and comply with certification procedures or otherwise establish an exemption from backup withholding.

A Non-U.S. Holder may be subject to U.S. information reporting and backup withholding on these payments unless the Non-U.S. Holder complies with certification procedures to establish that it is not a U.S. person (within the meaning of the Code). The certification requirements generally will be satisfied if the Non-U.S. Holder provides the applicable withholding agent with a statement on the applicable IRS Form W-8BEN or IRS Form W-8BEN-E (or suitable substitute or successor form), together with all appropriate attachments, signed under penalties of perjury, stating, among other things, that such Non-U.S. Holder is not a U.S. Person. Applicable Treasury Regulations provide alternative methods for satisfying this requirement. In addition, the amount of distributions on common stock or constructive dividends on common stock paid to a Non-U.S. Holder, and the amount of any U.S. federal tax withheld therefrom, must be reported annually to the IRS and the holder. This information may be made available by the IRS under the provisions of an applicable tax treaty or agreement to the tax authorities of the country in which the Non-U.S. Holder resides.

Payment of the proceeds of the sale or other disposition of the Common Stock or the Warrants to or through a non-U.S. office of a U.S. broker or of a non-U.S. broker with certain specified U.S. connections generally will be subject to information reporting requirements, but not backup withholding, unless the Non-U.S. Holder certifies

under penalties of perjury that it is not a U.S. person or, an exemption otherwise applies. Payments of the proceeds of a sale or other disposition of the Common Stock or the Warrants to or through a U.S. office of a broker generally will be subject to information reporting and backup withholding, unless the Non-U.S. Holder certifies under penalties of perjury that it is not a U.S. person or otherwise establishes an exemption.

Backup withholding is not an additional tax. The amount of any backup withholding from a payment generally will be allowed as a credit against the holder’s U.S. federal income tax liability and may entitle the holder to a refund, provided that the required information is timely furnished to the IRS.

Foreign Account Tax Compliance Act

FATCA imposes withholding tax on certain types of payments made to foreign financial institutions and certain other non-U.S. entities. The legislation imposes a 30% withholding tax on dividends on, or, subject to the discussion of certain proposed Treasury Regulations below, gross proceeds from the sale or other disposition of, our Common Stock or the Warrants paid to a “foreign financial institution” or to certain “non-financial foreign entities” (each as defined in the Code), unless (i) the foreign financial institution undertakes certain diligence and reporting obligations, (ii) the non-financial foreign entity either certifies it does not have any “substantial United States owners” (as defined in the Code) or furnishes identifying information regarding each substantial United States owner, or (iii) the foreign financial institution or non-financial foreign entity otherwise qualifies for an exemption from these rules. If the payee is a foreign financial institution and is subject to the diligence and reporting requirements in (i) above, it must enter into an agreement with the U.S. Treasury requiring, among other things, that it undertake to identify accounts held by “specified United States persons” or “United States-owned foreign entities” (each as defined in the Code), annually report certain information about such accounts, and withhold 30% on payments to account holders whose actions prevent it from complying with these reporting and other requirements. If the country in which a payee is resident has entered into an “intergovernmental agreement” with the United States regarding FATCA, that agreement may permit the payee to report to that country rather than to the U.S. Department of the Treasury. The U.S. Treasury recently released proposed Treasury Regulations which, if finalized in their present form, would eliminate the federal withholding tax of 30% applicable to the gross proceeds of a sale or other disposition of our Common Stock or the Warrants. In its preamble to such proposed Treasury Regulations, the U.S. Treasury stated that taxpayers may generally rely on the proposed regulations until final regulations are issued. Prospective investors should consult their own tax advisors regarding the possible impact of these rules on their investment in our Common Stock or the Warrants, and the possible impact of these rules on the entities through which they hold our Common Stock or the Warrants, including, without limitation, the process and deadlines for meeting the applicable requirements to prevent the imposition of this 30% withholding tax under FATCA.

THE PRECEDING DISCUSSION IS FOR GENERAL INFORMATION ONLY. EACH PROSPECTIVE INVESTOR SHOULD CONSULT ITS TAX ADVISOR REGARDING THE PARTICULAR U.S. FEDERAL, STATE AND LOCAL AND NON-U.S. TAX CONSEQUENCES OF PURCHASING, HOLDING AND DISPOSING OF OUR COMMON STOCK, INCLUDING THE CONSEQUENCES OF ANY PROPOSED CHANGE IN APPLICABLE LAWS.

PLAN OF DISTRIBUTION

Maxim Group LLC is acting as our exclusive placement agent to solicit offers to purchase the securities offered by this prospectus. We and the placement agent intend to enter into a placement agency agreement with respect to the shares of Common Stock being offered hereby. The placement agent is not purchasing or selling any securities, nor is it required to arrange for the purchase and sale of any specific number or dollar amount of securities, other than to use its “reasonable best efforts” to arrange for the sale of the securities by us. Therefore, we may not sell the entire amount of securities being offered. There is no minimum amount of proceeds that is a condition to closing of this offering. We will enter into one or more securities purchase agreements directly with the investors, at each investor’s option, who purchase our securities in this offering. Investors who do not enter into a securities purchase agreement shall rely solely on this prospectus in connection with the purchase of our securities in this offering. The placement agent may engage one or more subagents or selected dealers in connection with this offering.

The placement agency agreement will provide that the placement agent’s obligations are subject to conditions contained in the placement agency agreement and the securities purchase agreement, as applicable.

We will deliver the shares of Common Stock being issued to the investors upon receipt of investor funds for the purchase of the shares of Common Stock offered pursuant to this prospectus. We anticipate the initial delivery of the shares of Common Stock being offered pursuant to this prospectus on or about            , 2023.

Placement Agent Fees and Expenses

Upon each closing, we will pay the placement agent a cash transaction fee equal to 7.0% of the aggregate gross cash proceeds to us from the sale of the Securities in the offering. Pursuant to the placement agency agreement, we will agree to reimburse the placement agent for its expenses payable by us, in an aggregate amount not to exceed $100,000 in the event of a closing of this offering, and up to $50,000 in the event that there is not a closing of this offering.

Effect of Performance of the Purchase Agreement on Our Shareholders

Table of our Common Stock that may be available for us to sell pursuant to the Purchase Agreement.Contents

If and when we do sell shares of our Common Stock to Lincoln Park, after Lincoln Park has acquired the Common Stock, Lincoln Park may resell all, some or none of those shares of our Common Stock at any time or from time to time in its discretion. Therefore, sales to Lincoln Park by us under the Purchase Agreement may result in substantial dilution to the interests of other holders of our shares of Common Stock. In addition, if we sell a substantial number of shares of our Common Stock to Lincoln Park under the Purchase Agreement, or if investors expect that we will do so, the actual sales of our Common Stock 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 Common Stock to Lincoln Park and the Purchase Agreement may be terminated by us at any time at our discretion without any cost to us.

The Texas Business Organizations Code or the TBOC,(the “TBOC”) permits a corporation to indemnify a director who was, is or is threatened to be a named defendant or respondent in a proceeding as a result of the performance of his duties if such person acted in good faith and, in the case of conduct in the person’s official capacity as a director, in a manner he reasonably believed to be in the best interests of the corporation and, in all other cases, that the person reasonably believed his conduct was not opposed to the best interests of the corporation and with respect to any criminal action or proceeding, that such person had no reasonable cause to believe his conduct was unlawful.

Subject to certain exceptions, the TBOC further permits a corporation to eliminate in its certificate of formation all monetary liability of the corporation’s directors to the corporation or its shareholders for conduct in performance of such director’s duties. Our amended and restated certificate of formation (the “Certificate of Formation”) provides that a director of the Company will not be liable to the Company or its shareholders for monetary damages for any act or omission by the director in the performance of his duties, except that, pursuant to the TBOC, there will be no limitation of liability to the extent the director has been found liable under applicable law for: (i) breach of the director’s duty of loyalty owed to theour Company or itsour shareholders; (ii) an act or omission not in good faith that constitutes a breach of duty of the director to theour Company or that involves intentional misconduct or a knowing violation of the law; (iii) a transaction from which the director received an improper benefit, regardless of whether the benefit resulted from an action taken within the scope of the director’s duties; or (iv) an act or omission for which the liability of the director is expressly provided for by an applicable statute.

Sections 8.101 and 8.103 of the TBOC provide that a corporation may indemnify a person who was, is or is threatened to be a named defendant or respondent in a proceeding because the person is or was a director only if a determination is made that such indemnification is permissible under the TBOC: (i) by a majority vote of the directors who at the time of the vote are disinterested and independent, regardless of whether such directors constitute a quorum; (ii) by a majority vote of a board committee designated by a majority of disinterested and independent directors and consisting solely of disinterested and independent directors; (iii) by special legal counsel selected by the Boardboard of Directorsdirectors or a committee of the Boardboard of Directorsdirectors as set forth in (i) or (ii); (iv) by the shareholders in a vote that excludes the shares held by directors who are not disinterested and independent; or (v) by a unanimous vote of the shareholders.

II-1


Section 8.104 of the TBOC provides that a corporation may pay or reimburse, in advance of the final disposition of the proceeding, reasonable expenses incurred by a present director who was, is or is threatened to be made a named defendant or respondent in a proceeding after the corporation receives a written affirmation by the director of his good faith belief that he has met the standard of conduct necessary for indemnification under Section 8.101 and a written undertaking by or on behalf of the director to repay the amount paid or reimbursed if it

is ultimately determined that he has not met that standard or if it is ultimately determined that indemnification of the director is not otherwise permitted under the TBOC. Section 8.105 also provides that reasonable expenses incurred by a former director, or a present or former employee, agent or officer of a corporation, who was, is or is threatened to be made a named defendant or respondent in a proceeding may be paid or reimbursed by the corporation, in advance of the final disposition of the action, as the corporation considers appropriate.

Section 8.105 of the TBOC provides that, subject to restrictions in its certificate of formation and to the extent consistent with other law, a corporation may indemnify and advance expenses to a person who is not a director, including an officer, employee or agent of the corporation as provided by: (i) the corporation’s governing documents; (ii) an action by the corporation’s governing authority; (iii) resolution by the shareholders; (iv) contract; or (v) common law. As consistent with Section 8.105, persons who are not directors may seek indemnification and advancement of expenses from the Company to the same extent that directors may seek indemnification and advancement of expenses from the Company.

Further, our amended and restated certificateCertificate of formationFormation and second amended and restated bylaws (the “Bylaws”) provide that we must indemnify our directors and officers to the fullest extent authorized by law. We believe that these indemnification provisions and the directors’ and officers’ insurance are useful to attract and retain qualified directors and executive officers.

We have also entered into indemnification agreements with each of our directors and certain of our officers. The indemnification agreements provide, among other things, for indemnification to the fullest extent permitted by the TBOC and our amendedCertificate of Formation and restated certificate of formation and second amended and restated bylawsBylaws against (i) any and all direct and indirect liabilities and reasonable expenses, including judgments, fines, penalties, interest and amounts paid in settlement of any claim with our approval and reasonable counsel fees and disbursements and (ii) any liabilities incurred as a result of serving as a director, officer, employee or agent (including as a trustee, fiduciary, partner or manager or in a similar capacity) of another enterprise or an employee benefit plan at our request. The indemnification agreements also provide for, or will provide for, the advancement or payment of expenses to the indemnitee and for reimbursement to us if it is found that such indemnitee is not entitled to such indemnification under applicable law and our amendedCertificate of Formation and restated certificate of formation and amended and restated bylawsBylaws or the terms of the indemnification agreements.

We expect to maintain standard policies of insurance that provide coverage (1) to our directors and officers against loss rising from claims made by reason of breach of duty or other wrongful act and (2) to us with respect to indemnification payments that we may make to such directors and officers.

Insofar as indemnification for liabilities arising under the Securities Act of 1933, as amended (the “Securities Act”), may be permitted to directors, officers or persons controlling us under any of the foregoing provisions, in the opinion of the SEC, such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.
