Adagio Medical Holdings, Inc. (Nasdaq: ADGM) (“Adagio” or “the Company”), a leading innovator in catheter ablation technologies for the treatment of cardiac arrhythmias, today announced that acute results from the Company’s FULCRUM-VT U.S. pivotal study have been accepted for presentation in a late-breaking clinical science session at The 20^th Annual International Symposium on Ventricular Arrhythmias, being held from October 10- 11, 2025 at the Philadelphia Marriott Downtown. The Investigational Device Exemption (“IDE”) study is the first study powered to evaluate the safety and effectiveness of Ultralow Temperature Cryoablation (“ULTC”) for the treatment of Sustained Monomorphic Ventricular Tachycardia (SMVT) in patients with both ischemic and nonischemic cardiomyopathy.

“We are delighted that the FULCRUM-VT acute data will be featured as part of a late-breaking session at VT Symposium,” said Todd Usen, Chief Executive Officer of Adagio Medical. “On behalf of the entire Adagio Medical team, I want to thank all of the investigators, research coordinators and patients who have supported this study and whose commitment to serving this underserved population of patients will bring us one step closer to a purpose-built solution for VT. We thank the VT Symposium for this opportunity, and we look forward to the results being shared in Philadelphia.”

Adagio Medical’s ULTC technology will be featured in the following presentations during the VT Symposium:

About Adagio Medical Holdings, Inc.

Adagio is a medical device company focused on developing and commercializing products for the treatment of cardiac arrhythmias utilizing its novel, proprietary, catheter-based Ultra-Low Temperature Cryoablation (ULTC) technology. ULTC is designed to create large, durable lesions extending through the depth of both diseased and healthy cardiac tissue. The Company is currently focused on the treatment of ventricular tachycardia (VT) with its purpose-built vCLAS™ Cryoablation System, which is CE Marked and is currently under evaluation in the Company’s FULCRUM-VT U.S. IDE Pivotal Study.

About FULCRUM VT

FULCRUM-VT (Feasibility of Ultra-Low Temperature Cryoablation in Recurring Monomorphic Ventricular Tachycardia) is a prospective, multi-center, open-label, single-arm study, enrolling 206 patients with structural heart disease of both ischemic and non-ischemic cardiomyopathy, indicated for catheter ablation of drug refractory VT in accordance with current treatment guidelines. The results of the study will be used to apply for FDA premarket approval (PMA) for Adagio’s vCLAS™ Cryoablation System, potentially leading to the broadest industry indication for purely endocardial ablation of scar-mediated VT.

Adagio’s vCLAS™ Cryoablation System is commercially available for the treatment of monomorphic ventricular tachycardia in Europe and select other geographies but is limited to investigational use in the United States.
