Continued Clinical and Regulatory Progress on the HeartBeam AIMIGo™ System

Enrollment Complete in VALID-ECG Clinical Study That Will Be the Basis of the Upcoming FDA Submission on the 12-Lead Synthesis Software

Management to Host Webcast and Conference Call Today at 4:30 p.m. ET

HeartBeam, Inc. (NASDAQ:BEAT), a medical technology company focused on transforming cardiac care through the power of personalized insights, has reported its financial and operational results for the second quarter ended June 30, 2024.

Second Quarter & Subsequent 2024 Operational Highlights

The Company made steady progress toward key clinical and regulatory milestones on its HeartBeam AIMIGo™ System.

AIMIGo 510(k) Submission:

The 510(k) submission for the HeartBeam AIMIGo System is currently being reviewed by the FDA.
AIMIGo is a credit card-sized, cable-free cardiac monitoring device that will be capable of producing a 12-lead ECG by leveraging the Company's core vector technology, which captures 360-degree signals of the heart's electrical activity. The Company owns patents supporting the underlying technology.
This is the cornerstone submission for HeartBeam and will be the basis of future submissions.
The Company has successfully resolved the vast majority of the questions the FDA has asked. During the second quarter of 2024 the FDA requested additional information, which the Company is in the process of providing. The Company is working with the FDA to address the small number of remaining questions.
The Company continues to plan for a limited launch of AIMIGo by the end of 2024.

12-Lead Synthesis Software Submission:

HeartBeam has completed two pre-submission meetings with the FDA on the planned second 510(k) submission, which will be submitted after the initial clearance of the AIMIGo System.
The second submission is focused on the algorithms that convert the 360-degree signals captured by the AIMIGo System into a synthesized 12-lead ECG.
A key component of the submission will be the results of the VALID-ECG pivotal study, which is designed to demonstrate the similarity between the synthesized 12-lead ECG and a standard 12-lead ECG.
Patient enrollment for VALID-ECG was completed on June 20, 2024.
The Company currently anticipates submitting the 510(k) application soon after receiving clearance for the AIMIGo System.

Other Highlights:

New data presented at the European Heart Rhythm Association (EHRA) conference in April marked the first scientific presentation on HeartBeam AI, the Company's deep learning technology. The data validated that applying HeartBeam AI to vectorcardiography (VECG) delivered distinctly improved performance in the detection of atrial flutter over single-lead ECGs. Atrial flutter is a common arrhythmia that significantly increases a patient's risk for stroke.
Additionally, new data presented at the Heart Rhythm Society (HRS) Conference in May demonstrated that combining HeartBeam AI with VECG outperformed an expert panel of electrophysiologists in detecting atrial flutter when reviewing 12-lead ECGs. Data showed that applying AI to VECG data provides more consistent and reliable detection of atrial flutter.
HeartBeam AIMIGo was selected as winner of the "Best New ECG Technology Solution" award in the 8th annual MedTech Breakthrough Awards program.
HeartBeam was added to the Russell Microcap® Index effective after the market close on June 28, 2024.
Cash and cash equivalents totaled approximately $9.2 million as of June 30, 2024, enabling the Company to execute on upcoming clinical and regulatory milestones.

Management Commentary

"The second quarter of 2024 was highlighted by new data for the validation of HeartBeam AI, our deep learning technology, and ongoing progress with anticipated regulatory and clinical milestones for the AIMIGo vector technology platform," said Branislav Vajdic, PhD, Chief Executive Officer and Founder of HeartBeam. "We have successfully resolved the vast majority of questions the FDA has asked and are in the process of providing the additional information the FDA requested during the quarter. We are engaged in productive discussions with the FDA and believe that we are progressing toward clearance, which we anticipate later this year. We have created our initial Go-To-Market plan and will be testing this during our limited launch prior to the end of the year.

"Following the initial FDA clearance for the AIMIGo System, we plan to submit a second 510(k) application. This submission will include results from our pivotal VALID-ECG clinical study, which compares the AIMIGo synthesized 12-lead ECG to a standard 12-lead ECG in patients presenting to an outpatient cardiology clinic or arrhythmia center for symptoms suggestive of cardiac arrhythmia or for routine checkup of previously diagnosed arrhythmia. Due to strong interest, in June, we completed patient enrollment in this important 198-patient study after only three months of enrollment, which is extremely fast for a study of this size.

"We presented positive new data for our deep learning algorithm, HeartBeam AI, at two conferences during the quarter. The data showed that HeartBeam AI combined with VECG delivered equivalent performance to a 12-lead ECG, greatly improved detection of atrial flutter over a single-lead ECG, and even outperformed an expert panel of electrophysiologists in detecting atrial flutter. We believe this presents an opportunity for a vector-based algorithm that offers arrhythmia detection capabilities beyond what is available today.

"Looking ahead, our optimism continues for the FDA's clearance of the AIMIGo system and we are on track for the planned second 510(k) submission. We are encouraged by our progress in using artificial intelligence with our vector technology, showcasing the potential of our artificial intelligence program to improve diagnostic accuracy when a patient is outside of a medical facility. We also see strength in our product development pipeline, notably an extended wear patch for detecting heart attacks and complex cardiac arrythmias. This market is estimated to reach $4.8 billion by 2030. Interest from large industry players in partnering continues on key aspects of our portfolio. Our long-term vision is to transform the monitoring and detection of cardiac conditions through our vector-based technology. Our unique approach allows us to deliver the smallest, easiest to use cable-free 12-lead ECG to patients and their physicians in a variety of form factors and unlock actionable insights on a wide range of cardiac conditions," concluded Dr. Vajdic.
