HeartBeam, Inc. (NASDAQ:BEAT), a medical technology company focused on transforming cardiac care by providing powerful cardiac insights, has reported its financial and operational results for the fourth quarter and full year ended December 31, 2025.

Fourth Quarter & Subsequent 2026 Operational Highlights

The Company continues to make significant progress entering commercialization while advancing several key initiatives as part of its growth strategy:

Limited Launch:

U.S. Food and Drug Administration (FDA) granted 510(k) clearance for the Company's groundbreaking 12-lead electrocardiogram (ECG) synthesis software for the assessment of arrhythmias in December 2025.
Company is initiating a limited market release, focusing on select concierge and preventive cardiology groups that have proactively signaled strong interest in adopting HeartBeam's technology.
Signed first commercial partnership with ClearCardio™, a rapidly growing preventive cardiology practice with a highly engaged member population. They serve thousands of patients through advanced heart health screening and personalized prevention programs.
Includes an initial staged rollout to ensure a seamless patient and physician experience, facilitating plans for broader expansion across multiple U.S. geographies.
Established initial foothold in structured direct pay healthcare segment, representing 5 million patients in the U.S.

Heart Attack Detection:

Enrolled first patients in ALIGN-ACS pilot study evaluating the HeartBeam System for heart attack detection.
ALIGN-ACS pilot study expected to complete patient enrollment quickly as study is designed to enroll chest pain patients in the emergency department.
Milestone signifies key step toward future FDA indication expansion for heart attack assessment.
Future indication expansion would unlock large market with over 20 million patients at risk of a heart attack.

12-lead ECG Extended Wear Patch:

Completed the first working prototype of an extended-wear ECG patch which the Company believes is the first ECG patch capable of offering 12-lead ECG signals.
Potential to be a best-in-class offering addressing a significant clinical gap in an existing multi-billion-dollar market with reimbursement.
Product demonstrations to be provided at the American College of Cardiology's annual scientific conference March 28-30, 2026, in New Orleans.

AI Program:

Announced strategic collaboration with the Icahn School of Medicine at Mount Sinai to accelerate the joint development and validation of next-generation AI-ECG algorithms.
Combining Mount Sinai's world-class AI and clinical expertise with HeartBeam's groundbreaking 3D ECG signal collection technology to develop increasingly personalized algorithms.
HeartBeam is the only platform capable of collecting longitudinal synthesized 12-lead ECG data from patients anytime, anywhere – bringing clinical-grade monitoring into patients' daily lives.
Positions HeartBeam to expand from symptom-based cardiac rhythm monitoring into AI-enabled disease assessment and management.

Other Commercialization and Operational Highlights:

Appointed Bryan Humbarger as Chief Commercial Officer to lead commercial strategy and execution across the Company's key growth initiatives.
Cash and cash equivalents totaled $4.4 million as of December 31, 2025, with net cash used in operating activities of $2.9 million for the three-month period ended December 31, 2025, resulting in a 30% decrease compared to same quarter in the prior year.

Management Commentary

"The fourth quarter of 2025 and early 2026 were transformational for HeartBeam, culminating in the FDA 510(k) Clearance for our 12-Lead ECG synthesis software. With that clearance, we are now prepared to start a limited commercial launch for our credit card sized 12-lead ECG device in the arrhythmia market," said Robert Eno, Chief Executive Officer, HeartBeam.

"HeartBeam's technology is a true platform. We believe that our unique and patented technology is the only way for patients to obtain a 12-lead ECG at home or wherever they have symptoms, through a small, easy to use, cable free device.

"Our core technology can be applied to multiple form factors. In the background, we also have been developing a second form factor, an on-demand 12-lead patch. We believe that this can disrupt the long-term continuous monitor and mobile cardiac telemetry, or MCT markets, a combined $2B revenue market with established reimbursement. The technology in these two form factors has the potential to enable a full range of 12-lead ECG capabilities, including arrhythmia, heart attack detection, and personalized AI algorithms.

"Through our platform, we are creating an ecosystem that will add unique insights and actionable data for both patients and physicians that are unavailable elsewhere and add to the premium offering of HeartBeam. We are incredibly excited by the progress made to date on our key growth initiatives and look forward to providing updates as we continue to execute on our vision," concluded Eno.
