Adagio Medical Provides Business Updates

Adagio Medical Holdings, Inc. (NASDAQ:ADGM, the "Company"))), a leading innovator in catheter ablation technologies for treatment of cardiac arrhythmias, today provided a business update.

Recent Business Highlights:

• Obtained CE Mark approval and initiated commercial launch of the vCLAS™ catheter and ultra-low temperature cryoablation (ULTC) system for treatment of ventricular tachycardia (VT) into select European markets
• Presented CRYOCURE-VT trial data at European Heart Rhythm Association and Heart Rhythm Society annual meetings with results published in EP Europace journal
• Obtained the U.S. Food and Drug Administration ("FDA") approval for the FULCRUM-VT Pivotal IDE study
• Closed business combination and PIPE financing and listed the Company's common stock on The Nasdaq Capital Market

"For years there has been underinvestment in and pent-up demand for innovation in ablation catheter technology for patients with VT," said Olav Bergheim, Chief Executive Officer of Adagio Medical. "Adagio's proprietary ULTC platform holds the promise to solve a number of unique technical and clinical challenges which make VT ablations complex and time-consuming, resulting in underutilization of this potentially life-altering therapeutic procedure. We've received consistent, positive feedback from physicians regarding our published clinical data, and we are seeing a similar reception in the initial commercial cases in Europe. Turning to the US and our FULCRUM-VT Pivotal Study, there has been a strong interest in study participation among the top VT ablation centers. We expect patient enrollment to start in September, and look forward to providing updates on our progress."

FULCRUM-VT Pivotal IDE Study is a prospective, multi-center, open label, single-arm study which will evaluate safety and effectiveness of Adagio Medical VT Cryoablation System in patients with sustained monomorphic VT due to structural heart disease of both ischemic and non-ischemic origin. The study will enroll 206 patients at twenty US and Canadian centers, with Roderick Tung (Banner University Medical Center Phoenix, Phoenix, AZ, USA) and Atul Verma (McGill University Health Centre, Montreal, Canada) serving as study co-principal Investigators. The FDA approved the Pivotal IDE protocol in May 2024. The initial, Early Feasibility (EFS) stage of FULCRUM-VT has enrolled 20 patients at Banner University Medical Center Phoenix, Phoenix, AZ, Vanderbilt University Medical Center Nashville, TN, Mount Sinai Hospital New York, NY, and University of California in San Francisco, CA.
