Adagio Medical Holdings, Inc. filed an amendment to its Annual Report for the year ended December 31, 2025 to replace Exhibits 31.1 and 31.2. The change corrects an inadvertent omission of language in paragraph 4 of the principal executive and financial officer certifications required under Section 302 of the Sarbanes-Oxley Act.
The amendment does not alter any other part of the original Annual Report and does not update disclosures for subsequent events. As of June 30, 2025, the aggregate market value of common stock held by non-affiliates was $7.0 million, and as of March 23, 2026, there were 22,210,459 common shares outstanding.

Adagio Medical Holdings, Inc. reported that Nasdaq has notified the company its common stock no longer meets the Nasdaq Listing Rule 5550(a)(2) minimum bid price requirement. The stock has closed below $1.00 per share for the past 30 consecutive business days.
The company has 180 calendar days, until December 9, 2026, to regain compliance while its shares continue trading on the Nasdaq Capital Market. Compliance would be restored if the bid price closes at or above $1.00 for at least ten consecutive trading days.
If compliance is not regained by that date, Adagio may qualify for a second 180‑day period if it meets other Nasdaq Capital Market initial listing standards and indicates an intent to regain compliance, potentially through a reverse stock split. Failure to satisfy these conditions could result in delisting of its common stock.
Adagio Medical Holdings, Inc. has submitted a Premarket Approval (PMA) application to the U.S. Food and Drug Administration for its vCLAS Ventricular Ablation System to treat drug‑refractory, recurrent, sustained monomorphic ventricular tachycardia in patients with ischemic or non‑ischemic structural heart disease.
The PMA is supported by a pivotal IDE trial of 209 patients across 20 electrophysiology centers, showing 97.4% acute clinical success and strong six‑month results, including 84.3% freedom from ICD therapy, 2.4% major adverse events and a 78% reduction or elimination of anti‑arrhythmic drug use. The device has Breakthrough Device Designation and targets what the company describes as a $5.8 billion VT ablation market, with vCLAS already commercially available for VT treatment in Europe and select other regions but limited to investigational use in the United States.

Adagio Medical Holdings, Inc. reported another pre-revenue quarter for the three months ended March 31, 2026, as it continues developing ablation technologies for cardiac arrhythmias. The company recorded no revenue and a net loss of $6.995 million, or $0.31 per share, compared with a $7.713 million loss a year earlier.
Operating expenses fell to $5.2 million from $7.4 million, but cash used in operations was $4.1 million. Cash and cash equivalents were $12.9 million, and total stockholders’ equity declined to $5.7 million while convertible notes and related fair value adjustments brought total liabilities to $33.6 million.
Management states there is substantial doubt about the company’s ability to continue as a going concern, as existing cash is expected to fund operations only into the third quarter of 2026. The company plans to pursue additional equity or debt financing, regulatory approvals to support commercialization, and cost-cutting measures.
Adagio Medical Holdings, Inc. reported first quarter 2026 results showing continued operating losses alongside clinical progress in its ventricular tachycardia program. The company generated no revenue for the quarter, reflecting its focus on development activities rather than commercial sales.
Operating expenses declined, with research and development at $2.7 million and selling, general and administrative costs at $2.5 million, both down from the prior year period. Net loss improved modestly to $7.0 million, or $0.31 per share, compared with a net loss of $7.7 million a year earlier.
