Added

For example, we recently received FDA Clearance for HeartBeam’s 12-lead ECG synthesis software for arrhythmia assessment and are initiating a market introduction in early 2026, focusing on select concierge and preventive cardiology groups that have proactively signaled strong interest in adopting HeartBeam’s technology. Future versions of our Products may include an expansion of our cleared indications through a heart attack detection indication, an on-demand 12L ECG extended wear patch monitor, and AI-based screening and prediction algorithms. In the future, if we make modifications to our technology, the FDA may have to find that the modifications are substantially equivalent to the currently cleared HeartBeam System and, thus, may not be lawfully marketed in the U.S. until the FDA makes a substantial equivalence determination and issues the requisite 510(k) clearance or de novo classification for the modified HeartBeam System. The FDA may determine that the device is not substantially equivalent and require a PMA or, more likely, a de novo reclassification, and/or require further information, such as additional test data, including data from clinical studies, before it is able to make a determination regarding substantial equivalence. By requesting additional information, the FDA can delay market introduction of our Platform. Delays in receipt of or failure to receive any necessary 510(k) clearance, de novo classification, or the imposition of stringent restrictions for our products could have a material adverse effect on our business, results of operations and financial condition.

Reworded

The ability of physicians and other providers to successfully utilize our cardiac diagnostic and monitoring solutions and successfully allow payorspayers to reimburse for the physicians’ technical and professional fees is critical to our business because physicians and their patients will select solutions other than ours in the event that payorspayers refuse to adequately reimburse our technical fees and physicians’ professional fees.

Reworded

We may experience difficulty in obtaining reimbursement for our services from commercial payorspayers that consider our technology to be experimental and investigational, which would adversely affect our revenue and operating results.

Reworded

Many commercial payorspayers refuse to enter into contracts to reimburse the fees associated with medical devices or services that such payorspayers determine to be “experimental and investigational.” Commercial payorspayers typically label medical devices or services as “experimental and investigational” until such devices or services have demonstrated product superiority evidenced by a randomized clinical trial.

Reworded

For example, clinical trials have been performed on some mobile cardiac telemetry devices, proving higher diagnostic yield than monitoring devices and services that are already being reimbursed. Certain remaining commercial payors,payers, however, have stated that they do not believe the data from the clinical trials justifies the removal of the experimental designation for mobile cardiac telemetry solutions. As a result, certain commercial payorspayers may refuse to reimburse the technical and professional fees associated with cardiac monitoring solutions such as the one expected to be offered by the Company.

Reworded

If commercial payorspayers decide not to reimburse physicians or providers for their services during the utilization of our cardiac monitoring solutions, our revenue could fail to materialize or meet our projections.

Reworded

Consolidation of commercial payorspayers could result in payorspayers eliminating coverage of mobile cardiac monitoring solutions or reducing reimbursement rates.

Reworded

When payorspayers combine their operations, the combined company may elect to reimburse physicians for cardiac monitoring services at the lowest rate paid by any of the participants in the consolidation. If one of the payorspayers participating in the consolidation does not reimburse for these services at all, the combined company may elect not to reimburse at any rate. Reimbursement rates tend to be lower for larger payors.payers. As a result, as payorspayers consolidate, our expected average reimbursement rate may decline.

WeHeartBeam areis a medical technology company focused on transforming cardiac care through the power of personalized insights. Our aim is to deliver innovative, higher resolution ambulatory cardiac monitoring solutions that can be used by patients anywhere to enable the detection and monitoring of cardiac disease outside of a healthcare facility. Our ability to develop higher resolution Electrocardiogram (“ECG”) solutions is achieved through the development of our proprietary and patented technology platform that allows us to collect the heart’s electrical activity from three distinct directionsdimensions and synthesize a 12-Lead (“12L”) ECG from these signals. Our approach has demonstrated comparable diagnostic capability to a traditional hospital-based 12L ECG system in recent studies. The data from these studies was also submitted to FDA as part of our recent FDA submission.

Removed

Our Products (“Product” or “Products”) require U.S. Food and Drug Administration (“FDA”) clearance. The HeartBeam System (defined below) was granted FDA clearance on December 13, 2024. We believe the HeartBeam System is the first FDA cleared cable-free, ambulatory ECG that captures the heart’s electrical signals from three distinct directions for high-fidelity data collection and advanced diagnostics.

Reworded

We believe our Products (“Products” or “Product”) and services will benefit many stakeholders, including patients, healthcare providers, and healthcare payors.payers, Weand arewill developing our Product, (the “HeartBeam System”, previously referred to as “AIMIGo™”), toalso address the rapidly growing field of ambulatory cardiac health monitoring. TheAs HeartBeam System is comprisedpart of aour creditlong-term cardvision, sized electrocardiogram device, a patient application, a physician portal, and powerful cloud-based algorithms. Wewe believe that we are uniquely positioned to play a central role in ambulatory cardiac monitoring including high-risk Coronary Artery Disease (“CAD”) patients,monitoring, becausegiven positive, proof-of-concept data from the initial feasibility studies have shown that ourdemonstrated comparable performance of the HeartBeam System and the standard 12L ECG in ischemia detection tool may be more accurate than existing ambulatory monitoring solutions.detection. CAD patients are at increased risk for a heart attack or Myocardial Infarction (“MI”). Additionally, our unique portable form-factor will make high-fidelity insights easily accessible, wherever patients are, compared to a standard 12L ECG, which is typically limited to a healthcare setting.

Added

Our initial product and service offering is the HeartBeam System. The HeartBeam System is the first U.S. Food and Drug Administration (“FDA”) cleared cable-free, ambulatory 12L ECG that captures the heart’s electrical signals from three dimensions for high-fidelity data collection and advanced diagnostics for arrhythmia assessment. The HeartBeam System is comprised of a credit card sized 3D ECG recording device, a patient application, a physician portal, and powerful cloud-based algorithms. Unlike any single-lead or 6-lead consumer device, HeartBeam’s patented cable-free technology captures the heart’s electrical signals in three non-coplanar dimensions and synthesizes them into a familiar 12L ECG display, using a personalized transformation matrix. This allows patients to obtain a 12L ECG reading for their arrhythmia from the comfort of home, or wherever they happen to be, representing a new level of convenience and peace of mind. The synthesized 12-lead ECG is promptly reviewed by an on-demand, board-certified cardiologist.

Added

HeartBeam’s credit card sized 3D ECG technology received FDA clearance for arrhythmia assessment in December 2024 and the 12-Lead ECG synthesis software received FDA clearance for arrhythmia assessment in December 2025.

Added

We are focused on advancing several key initiatives as part of our growth strategy:

Added

Limited Launch: On the back of our recent FDA Clearance for the HeartBeam System, we are initiating a market introduction in early 2026, focusing on select concierge and preventive cardiology groups that have proactively signaled strong interest in adopting HeartBeam’s technology. This limited market release will enable the Company to validate real-world performance and establish reference sites for broader commercialization.

Added

Heart Attack Detection: We are pursuing an expansion of our cleared indications through a heart attack detection indication, supported by compelling proof-of-concept data and representing a major expansion opportunity to tens of millions of patients in the U.S.

Added

Extended Wear Patch: We are making significant advancements with an on-demand 12L ECG extended wear monitor. The Company has developed a working prototype of its novel 12L patch, which has the potential to be a best-in-class offering in an existing multi-billion-dollar market with reimbursement.

Added

Longitudinal Data and AI: The Company believes it has the ability to unlock the power of the unique data-rich repository generated from our 3D ECG platform and deep learning algorithms. As adoption grows, the ability for patients to record synthesized 12L ECGs over time will create the opportunity to build AI-based screening and prediction algorithms that go beyond what is possible with single-timepoint ECGs or traditional wearables.

Added

As of December 31, 2025, we had 16 employees. In January 2026, the Company hired a Chief Commercial Officer, Bryan Humbarger, bringing total headcount to 17 employees. Mr. Humbarger brings more than 25 years of experience in building and scaling groundbreaking medical technologies. While initially focused on launching the Company’s FDA-cleared 12L system for arrhythmia assessment, he will lead the Company’s broader commercialization strategy across key growth initiatives, including heart attack detection and the 12L ECG extended wear patch.

Removed

In January 2025, the Company filed a 510(k) notification for the software algorithms that synthesize a 12L ECG from the HeartBeam System. This latest submission builds on HeartBeam’s recent FDA clearance for its patented technology, which captures the heart’s electrical signals from three distinct directions. The software synthesizes these signals into a familiar 12-lead ECG using a personalized transformation matrix.

Removed

The cumulative result of these two 510(k) submissions, once cleared by the FDA, will be an ambulatory device, carried by patients, which can synthesize a 12L ECG for physician review for arrhythmia assessment.

Removed

In support of this recent submission, the Company held two pre-submission meetings with the FDA on this 12L synthesis submission. These meetings focused primarily on the performance goals of our clinical study designed to demonstrate the similarity between our synthesized 12L signal and the output of a standard 12L ECG for the intended use. Based on feedback from FDA and our clinical experts, the Company designed a prospective multicenter pivotal study, the VALID-ECG pivotal study, for clinical validation of the HeartBeam 12 Lead ECG Synthesis Software for Arrhythmia Detection.

Removed

This latest FDA submission is backed by robust data from the VALID-ECG study, which enrolled 198 patients across five clinical sites. The Company believes the study's findings support the clinical equivalence of HeartBeam's synthesized 12-lead ECG where the leads are similar to standard 12-lead ECGs for rhythm and arrhythmia assessment. Efforts were made to enroll patients with a diverse demographic profile reflective of the intended use population in the United States. The primary objective was to demonstrate the equivalence of ECG waveforms between the HeartBeam System Synthesized 12L ECG and Standard 12L ECG, recorded simultaneously in each subject, by assessing relevant ECG characteristics, i.e. intervals and amplitudes.

Removed

The Company is in the process of initiating an Early Access Program for the HeartBeam System. This program will provide the company with valuable feedback on the user experience, overall workflow and functionality of the system in a real-world setting. The Early Access Program will also help prepare the Company to commercialize the technology once we receive FDA clearance for our 12L synthesis algorithm. We do not anticipate that the HeartBeam System clearance will generate significant revenue before the clearance of the synthesized 12L algorithm.

Removed

We also have an active AI program underway. We have acquired approximately one million 12L ECGs from various sources, a key element in our fast-paced AI development efforts.

Removed

We have developed initial deep learning algorithms, focused on the ability to detect various cardiac arrhythmias. HeartBeam has had data on its deep learning algorithm presented at two prestigious Electrophysiology conferences. Data were presented at the European Heart Rhythm Association in Berlin, Germany in April 2024 and at the Heart Rhythm Society, in Boston, MA in May 2024. We believe that, when combined with our Products, HeartBeam’s AI will provide additional value to patients and physicians in several ways, including:

Removed

• Providing automated classification of cardiac conditions, including common arrhythmias,

Removed

• Potentially enhancing user experience and simplify the onboarding process, and

Removed

• In the longer run, we believe that applying deep learning algorithms on top of the rich data, especially with the longitudinal dataset from patients taking repeated readings, may result in unsurpassed predictive and diagnostic capabilities.

Removed

The custom software and hardware of our Products are classified as Class II medical devices by the FDA. Premarket review and clearance by the FDA for Class II devices is generally accomplished through the 510(k) premarket notification process or De Novo process. Given the proposed intended use of our device, the 510(k) submission or De Novo process is expected to require clinical data to support FDA clearance.

Reworded

We believe our products (“Products” or “Product”) and services will benefit many stakeholders, including patients, healthcare providers, and healthcare payers, and will also address the rapidly growing field of ambulatory cardiac monitoring. As part of our long-term vision, we believe that we are uniquely positioned to play a central role in high-risk Coronary Artery Disease (“CAD”) monitoring, given positive, proof-of-concept data from the initial feasibility studies that demonstrated comparable performance of the HeartBeam System and the standard 12L12-lead ECG in ischemia detection. CAD patients are at increased risk for a heart attack or Myocardial Infarction (“MI”). Additionally, our unique portable form-factorform-factors will make high-fidelity insights easily accessible, wherever patients are, compared to a standard 12L12-lead ECG, which is typically limited to a healthcare setting,setting. workingThis will allow our technology to work in synergy with the standard of care to expedite diagnosis and appropriate intervention.

Added

We believe we have created the most info-rich ambulatory ECG signal available, led by our patented 3D signal technology. It is one platform, with many form factors. This platform technology is designed for portable devices that can be used wherever the patient is to deliver actionable heart intelligence. Physicians will be able to identify cardiac health trends and acute conditions and direct patients to the appropriate care – all outside of a medical facility, thus redefining the future of cardiac health management.

Added

The Company is focused on executing on a $40 billion cardiac monitoring platform opportunity, going after a patient pool of more than 50 million people across multiple applications and form factors.

Reworded

Our initial productform factor and service offering is the HeartBeam System. The HeartBeam System is the first U.S. Food and Drug Administration (“FDA”) cleared cable-free, ambulatory synthesized 12L12-lead ECG that captures the heart’s electrical signals from three dimensions for high-fidelity data collection and advanced diagnostics for arrhythmia assessment. The HeartBeam System is comprised of a credit card sized 3D ECG recording device, a patient application, a physician portal, and powerful cloud-based algorithms. Unlike any single-lead or 6-lead consumer device, HeartBeam’s patented cable-free, 3D technology captures the heart’s electrical signals in three non-coplanar dimensions and synthesizes them into a familiar 12L12-lead ECG display, using a personalized transformation matrix. This allows patients to obtain a 12L12-lead ECG reading for their arrhythmia from the comfort of home, or wherever they happen to be, representing a new level of convenience and peace of mind. The synthesized 12-lead ECG is promptly reviewed by an on-demand, board-certified cardiologist for arrhythmia assessment.

Reworded

HeartBeam’s credit card sized 3D ECG technology received FDA clearance for arrhythmia assessment in December 2024 and the additional 12-Lead ECG synthesis software received FDA clearance for arrhythmia assessment in December 2025. During the threesix months ended MarchJune 31,30, 2025 and MarchJune 31,30, 2026, the HeartBeam System did not generate any revenue.

Added

Future form factors include the 12-Lead Patch and a ruggedized, industrial form factor for rural and international usage.

Added

Strategic Focus

Added

In June 2026, the Company announced a strategic shift in order to accelerate the global adoption of its ambulatory ECG signal platform.

Reworded

WeThe areCompany is focused on advancing several key initiatives as part of ourthis growth strategy:

Added

Licensing our 3D ECG signal technology to established partners, moving beyond direct medical device sales

Added

AI can only deliver actionable insight based on the quality of the signal it is given. HeartBeam has built what it believes is the best ambulatory ECG signal-acquisition platform — a data-rich 3D signal that is the input AI needs to move from inference to true detection.

Added

The Company believes it can extract remarkably accurate, clinical-grade recordings directly from its groundbreaking 3D signal-acquisition and ECG processing platform, turning more than a decade of signal science into an immediately actionable foundation.

Added

The Company plans to license its technology to help serve third-party AI platforms being developed across medicine that depend on high-quality, real-world ECG data.

Added

Tailoring our technology to fit each market

Added

HeartBeam intends to achieve global adoption by partnering its breakthrough patented 3D ECG platform across the five channels that already have distribution — governments and national health systems, ECG OEMs, Holter and patch manufacturers, health systems and integrated delivery networks, and consumer wearable companies — and by adapting its technology to the form factor each use case requires.

Added

The Company believes its technology can be adapted to multiple form factors; from a ruggedized unit that lets a rural health clinic triage a patient in minutes, an adhesive patch for longer-term monitoring, a simpler form factor for an older or less agile patient, or a sleek, compact card an expert user slips into a wallet.

Added

The Company continues to make significant advancements with its on-demand 12-lead ECG extended wear monitor. The Company has developed a working prototype of its novel 12-lead patch, which has the potential to be a best-in-class offering in an existing multi-billion-dollar market with reimbursement. We are in discussions with potential strategic partners and we continue to explore opportunities for partnership. We believe that this 12-lead patch can disrupt the Ambulatory Cardiac Monitoring market, a $2B revenue market with established reimbursement, that consists of the long-term continuous monitor and mobile cardiac telemetry or MCT segments.

Added

Advancing toward heart attack detection as a key expansion of the platform

Added

In June 2026, the Company completed enrollment in the ALIGN-ACS pilot study, ahead of its previously communicated Q3 2026 timeline. The study enrolled 120 patients presenting with chest pain across two emergency department sites in Belgrade, Serbia. Patients were evaluated using both a standard 12-lead ECG and the HeartBeam device, and both results compared with each patient’s final diagnosis at discharge.

Added

Data analysis is underway, and the findings are expected to inform the design and de-risk operational assumptions for the Company’s planned U.S pivotal study and support a future FDA submission to expand the HeartBeam System’s indication to include heart attack detection.

Added

Advancing our limited commercial launch in order to provide key learnings

Reworded

Limited Launch: On the back of our recent FDA Clearance for the HeartBeam System, we are initiatinginitiated a market introduction in early 2026, focusing on select concierge and preventive cardiology groups that have proactively signaled strong interest in adopting HeartBeam’s technology. This limited market release will enable the Company to validate real-world performance and establish reference sites for broader commercialization.

Added

In May 2026, the Company announced a commercial agreement with Atelier Health, a premier concierge medical practice led by physicians affiliated with Cedars-Sinai Medical Center. The collaboration underscores HeartBeam’s positioning within the high-value direct pay healthcare segment where adoption of innovative technologies can occur more rapidly and patients are seeking proactive cardiac insights tailored to their individual risk profiles. The initial agreement with Atelier Health is structured as a Letter of Intent (LOI), outlining the commercial terms and a collaborative rollout plan, including a subscription fee per patient. During the initial deployment phase, HeartBeam and Atelier Health intend to negotiate and execute a definitive agreement.

Added

The addition of Beverly Hills-based Atelier Health expands HeartBeam’s commercial footprint across four targeted launch markets – New York metro, Dallas, South Florida, and Southern California – completing an initial geographic footprint to advance the Company’s scalable go-to-market strategy in concierge and preventive cardiology.

Added

As of June 30, 2026, we had 16 employees. In June 2026, the Company announced that Rob Eno transitioned from the role of Chief Executive Officer to a consulting role.

Removed

In March 2026, the Company announced it enrolled the first patients in the ALIGN-ACS pilot study. The ALIGN-ACS pilot study is designed to enroll approximately 100 patients presenting with chest pain in the emergency room (ER). Patients will be evaluated with both a standard 12-lead ECG and the HeartBeam device, and both results will be compared with each patient’s final diagnosis at discharge. Two sites are currently actively enrolling patients, with enrollment completion expected in Q3 2026. The pilot study will be instrumental in designing a pivotal study and informing discussions with the FDA.

Removed

Extended Wear Patch: We are making significant advancements with an on-demand 12L ECG extended wear monitor. The Company has developed a working prototype of its novel 12L patch, which has the potential to be a best-in-class offering in an existing multi-billion-dollar market with reimbursement.

Removed

In March 2026, the Company unveiled the working prototype of the 12L patch. In addition to working just like existing patches and continually recording a patient’s heart rhythms with a single lead, HeartBeam’s patch has the ability to record an on-demand 12-Lead ECG by simply placing two fingers on the front of the device. We believe that this 12L patch can disrupt the Ambulatory Cardiac Monitoring market, a $2B revenue market with established reimbursement, that consists of the long-term continuous monitor and mobile cardiac telemetry or MCT segments.

Removed

In May 2026, the Company initiated a Pilot Study, representing a significant step in the clinical and regulatory pathway for the 12L patch.

Removed

Longitudinal Data and AI: The Company believes it has the ability to unlock the power of the unique data-rich repository generated from our 3D ECG platform and deep learning algorithms. As adoption grows, the ability for patients to record synthesized 12L ECGs over time will create the opportunity to build AI-based screening and prediction algorithms that go beyond what is possible with single-timepoint ECGs or traditional wearables.

Removed

In March 2026, the Company and the Icahn School of Medicine at Mount Sinai in New York (“Mount Sinai”) entered into strategic AI collaboration to bring clinical-grade heart monitoring into the home. This collaboration will aim to accelerate development of personalized cardiac AI on the HeartBeam platform for wellness and clinical applications, including assessing heart attack risk.

As of March 31, 2026, we had 17 employees. In January 2026, the Company hired a Chief Commercial Officer, Bryan Humbarger. Mr. Humbarger brings more than 25 years of experience in building and scaling groundbreaking cardiovascular technologies. While initially focused on launching the Company’s FDA-cleared 12L system for arrhythmia assessment, he will lead the Company’s broader commercialization strategy across key growth initiatives, including heart attack detection and the 12L ECG extended wear patch.

Reworded

We intend to strike a balance of managing our headcount in line with cash resources, while also, at the appropriate time, hiring or engaging additional full-time professionals, employees, and/or consultants in alignment with our growth strategy.resources. To that end, the Company does not anticipate the need to hire a large sales force during the initial launch of its HeartBeam System. We believe that a few well-placed resources will help provide the data points required to effectively invest into a broader launch based around a path to profitable growth.

Removed

Although the market is highly competitive for attracting and retaining highly qualified professionals in our industry, we continue our endeavor to find such candidates for our Company. Our management team and additional personnel that we may hire in the future will be primarily responsible for executing and implementing growth opportunities, making tactical decisions related to our strategy and pursuing opportunities to invest in new technologies through strategic partnerships and acquisitions.
