An abstract on HeartBeam's AI algorithm was presented at HRX Live 2025, demonstrating continued advancement of the Company's AI program.
HeartBeam was recognized as a global IP and technology leader in portable cardiac diagnostics in a new PatentVest report, ranking #2 worldwide in 12-lead ECG innovation out of 243 companies analyzed.
Three (3) new patents were issued in the quarter, with a total of 24 patents now issued worldwide.
ROTH Capital initiated coverage on HeartBeam with a Buy rating and $4 price target ahead of the anticipated FDA clearance for the 12-lead ECG synthesis software.

Management Commentary

"In the third quarter, we made significant progress with commercial readiness plans in anticipation of FDA clearance for the 12-lead ECG synthesis software submission for arrhythmia assessment," said Robert Eno, Chief Executive Officer, HeartBeam. "We continue to engage in positive and productive discussions with the FDA and our anticipated timeline for this clearance by year end remains intact. Combined with the foundational FDA clearance received in December 2024, this clearance marks a major inflection point for the Company to initiate our commercial launch.

"The focus of our commercial launch will be establishing HeartBeam as the first personal, cable-free, synthesized 12-lead ECG for arrhythmia assessment. At the core of our product offering is the HeartBeam System paired with a 24/7 cardiology reader service. The announcement of the partnership with HeartNexus will provide our users access to a network of U.S.-based, board-certified cardiologists specializing in cardiac test interpretation.

"While we remain laser-focused on achieving our upcoming FDA clearance and launching the HeartBeam System in the concierge and preventive cardiologist market, we continue to make meaningful progress on several fronts. Scientific data was presented on heart attack detection and our AI program, adding to our body of clinical evidence. Three new patents were issued last quarter on our core technology, bringing the total to 24 global patents. We are pleased to have been recognized as a world leader in IP for 12-lead ECGs. Taken together, we believe we are well positioned for long-term value creation for our shareholders," concluded Eno.
