Adagio Medical Reports Fourth Quarter and Full Year 2025 Results

Key Terms

catheter ablation medical

Catheter ablation is a minimally invasive medical procedure in which a thin, flexible tube is threaded into the heart to destroy tiny areas of tissue that cause abnormal heart rhythms, typically using heat or freezing. Investors watch it because growing use or improved success rates can shift demand for specialized medical devices, hospital procedures and follow-up care, alter treatment costs, and compete with drug or implantable alternatives — like repairing a faulty circuit to restore reliable performance.

ventricular tachycardia medical

A fast, abnormal heartbeat that starts in the heart’s lower chambers and can sharply reduce blood flow, potentially causing dizziness, fainting or, in severe cases, sudden collapse; picture an engine running so fast it loses power. For investors, ventricular tachycardia matters because demand for drugs, devices, diagnostic tests and emergency care tied to this condition affects clinical trial results, regulatory approvals, revenue prospects and legal or safety risks for healthcare companies.

premature ventricular contractions medical

Premature ventricular contractions are extra heartbeats that begin in the heart’s lower chambers and occur earlier than the next expected beat, often experienced as a skipped beat, flutter or extra thump. For investors, they matter because frequent or symptomatic PVCs can indicate underlying heart disease or drug side effects, affecting clinical trial safety, regulatory reviews, and potential liability or treatment costs—like a dashboard warning that could change a company’s health-related risks.

Investigational Device Exemption regulatory

An investigational device exemption (IDE) is a regulatory permission that allows a medical device maker to test an unapproved device in people so the device’s safety and effectiveness can be studied. For investors, an IDE matters because it marks a formal step toward regulatory approval—like getting a temporary test-drive permit—and influences clinical cost, timelines, and the likelihood a device will reach the market and generate revenue.

pivotal trial medical

A pivotal trial is a key test of a new medicine or treatment to see if it works and is safe enough to be approved by health authorities. It's like a final exam for a new product, and passing it is essential for bringing the treatment to the public.

LAGUNA HILLS, Calif.--(BUSINESS WIRE)-- 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 financial results for the fourth quarter ended December 31, 2025.

Fourth Quarter and Recent Business Highlights:

• Announced the peer-reviewed publication in Circulation: Arrythmia and Electrophysiology, highlighting results from the U.S. Early Feasibility Study evaluating ultralow temperature cardiac ablation (“ULTA”) for the treatment of scar-related ventricular tachycardia (“VT”), which demonstrated a favorable safety profile and no device- or procedure-related major adverse events in a real-world patient cohort of both ischemic and challenging non-ischemic patients
• Announced the successful completion of 13 cases with the vCLAS™ System under Expanded Access authorization from the U.S. Food and Drug Administration (“FDA”). The procedures, which included patients with premature ventricular contractions, were completed on patients who had previously failed ablations with conventional and/or experimental modalities
• Appointed industry veteran Sean Salmon to the Company’s Board of Directors, enhancing strategic and governance expertise; Sean recently retired from Medtronic, Inc after a distinguished 20+ year tenure, during which he held multiple senior global leadership roles across the company’s cardiovascular and diabetes businesses
• Strengthened executive leadership team with the appointments of Marie-Claude Jacques as Senior Vice President, Global Sales, and Antwan Gipson as Senior Vice President, Manufacturing & Operations, both seasoned senior executives who will help accelerate commercial readiness
• Attended multiple industry and investor conferences, which involved webcasts of the corporate presentation and multiple meetings with a large spectrum of investors
• Closed a private placement with gross proceeds of up to $50 million, led by a syndicate of healthcare-dedicated institutional investors; upfront proceeds of approximately $19 million expected to fund FDA submission activities and ongoing next generation catheter development, with potential for up to $31 million in additional gross proceeds upon the exercise of outstanding warrants
• Completed enrollment of the 209-patient FULCRUM-VT Pivotal FDA Investigational Device Exemption (“IDE”) trial intended to support the premarket approval application for the vCLAS™ System for ablation of VT
• Announced preliminary results from the FULCRUM-VT trial demonstrating 97% acute effectiveness and a favorable safety profile with the Company’s proprietary ultralow temperature technology

“2025 marked a pivotal year for Adagio as our first full year as a public company. We delivered a number of important milestones across the organization, which we believe significantly strengthen our position as we advance our ULTA technology towards commercialization,” said Todd Usen, Chief Executive Officer of Adagio. “Importantly, we completed enrollment of the 209-patient FULCRUM-VT pivotal IDE trial in just eleven months, studying a real-world population of patients with both ischemic and non-ischemic cardiomyopathy, all of whom were treated with an endocardial approach. With enrollment now complete, we look forward to presenting pivotal results at the Heart Rhythm Society conference next month. As we advance toward the potential approval of vCLAS, our team is focused on preparing for commercialization while continuing to develop our next generation vCLAS technology. We remain committed to bringing our differentiated and proprietary solutions to the large and underserved population of patients living with ventricular tachycardia.”

Fourth Quarter and Full Year 2025 Financial Results

Cost of revenue was $58 thousand for the three months ended December 31, 2025, compared to $1.5 million for the three months ended December 31, 2024. Cost of revenue was $0.7 million for the full year of 2025, compared to $3.3 million for the full year of 2024. Cost of revenue decreased year-over-year due to the pause of commercial activity in Europe and the related impact of an inventory buyback conducted in connection thereto.

Research and development expenses were $2.2 million for the three months ended December 31, 2025, compared to $3.4 million for the three months ended December 31, 2024. Research and development expenses were $10.6 million for the full year of 2025, compared to $12.2 million for the full year of 2024. R&D expenses decreased year-over-year primarily due to a decrease in quality assurance costs, fewer research and development projects and reduced headcount.

Selling, general and administrative expenses were $1.7 million for the three months ended December 31, 2025, compared to $4.1 million for the three months ended December 31, 2024. Selling, general and administrative expenses were $10.6 million for the full year of 2025, compared to $20.0 million for the full year of 2024. Selling, general and administrative expenses decreased year-over year primarily due to the absence of SPAC-related corporate expenses that were incurred in 2024 and a decrease in payroll and personnel expenses related to lower headcount during the year ended December 31, 2025.

Net loss was $3.3 million for the three months ended December 31, 2025, compared to a net loss of $57.4 million for the three months ended December 31, 2024. Net loss was $25.1 million for the full year of 2025, compared to a net loss of $75.0 million for the full year of 2024. The year-over-year decrease in net loss related primarily to a $49.2 million non-cash Impairment of Goodwill and Intangibles in 2024, reduction of expenses as well as a decrease in interest expense and the fair value revaluation of notes and warrants.

Cash and cash equivalents on December 31, 2025 were $17.1 million.
