Exhibit 99.1

Adagio Medical Reports Second Quarter 2026 Results

LAGUNA HILLS, CA, August 11, 2026 –

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 second quarter ended June 30, 2026.

Recent Business Highlights:

· Announced the successful treatment at the Hospital of University

of Pennsylvania of the first patient with the Company’s next-generation vCLASTM Ultra

Ultra-Low temperature ablation catheter (“ULTA”), which is designed to be faster and more maneuverable than the first generation

vCLASTM Ventricular Ablation System catheter, under Expanded Access authorization from the U.S. Food and Drug Administration

(“FDA”)

· Announced pivotal results from the 209-patient FULCRUM-VT trial, which

were presented in a late-breaking session at Heart Rhythm Society 2026, demonstrating a promising safety profile with only 2.4% protocol-defined

Major Adverse Events and six-month results of 84% freedom from implantable cardioverter defibrillator (“ICD”) shock and a

78% discontinuation or reduced dose of antiarrhythmic drugs, as well as equivalent results across both ischemic and non-ischemic cardiomyopathy

patients with the Company's proprietary ULTA technology

· Submitted Premarket Approval (“PMA”) application, supported by the FULCRUM-VT pivotal IDE

trial, to the FDA for the vCLAS Ventricular Ablation System for the treatment of drug-refractory, recurrent, sustained monomorphic ventricular

tachycardia (“VT”) in patients with ischemic or non-ischemic structural heart disease

“This quarter marked an inflection point

for Adagio as our team continues to execute and deliver on our critical milestones. The enthusiastic physician reception of our FULCRUM-VT

late-breaking data at HRS reinforced what we have long believed about the potential for this technology, and the successful treatment

of the first patient with vCLAS Ultra — a particularly complex case — was a powerful proof point for our next-generation

system.” said Todd Usen, Chief Executive Officer of Adagio Medical. “We believe our progress – combined with

the breadth of our clinical evidence for both ischemic and non-ischemic patients - positions our fully-endocardial ULTA platform as a

uniquely differentiated solution capable of treating the entire spectrum of cases in an addressable market that has long needed a purpose-built

solution. We remain focused on executing against the milestones ahead as we work to bring our proprietary technology to the many patients

who suffer from VT.”

Second Quarter 2026 Financial Results

Cost of revenue was nil for the three months ended

June 30, 2026, compared to $0.3 million for the three months ended June 30, 2025. The decrease was primarily attributable to the pause

in commercial activity in Europe. Depreciation expense related to consoles loaned to customers is generally classified within cost of

revenue; however, because the Company did not generate revenue during the three months ended June 30, 2026, such depreciation expense

is reflected within research and development expenses for the period.

Research and development expenses were $2.5 million

for the three months ended June 30, 2026 compared to $2.0 million for the three months ended June 30, 2025. The increase was primarily

attributable to higher product development costs, including consulting and prototyping expenses, and higher operational costs, including

the aforementioned depreciation expense, partially offset by lower clinical trial expenses.

Selling, general and administrative expenses were

$2.5 million for the three months ended June 30, 2026, compared to $2.4 million for the three months ended June 30, 2025. The increase

was primarily attributable to higher stock-based compensation expenses, partially offset by lower professional services expenses.

Net loss for the three months ended June 30, 2026,

was $6.7 million, or $(0.30) per share (Basic), compared to a net loss of $3.9 million, or $(0.26) per share (Basic), for the three months

ended June 30, 2025.

Weighted average shares of common stock outstanding,

basic and diluted, were 22,210,459 as of June 30, 2026. The Company's fully diluted share count includes all outstanding warrants; however,

for purposes of calculating net loss per share, warrants and certain other potentially dilutive securities are excluded as their inclusion

would be anti-dilutive.

Cash and cash equivalents were $7.7 million as of June 30, 2026.

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 ablation (“ULTA”, formerly known as ULTC) technology. ULTA is designed to create large footprint, titratable lesions

extending through the depth of both diseased and healthy cardiac tissue, all through an endocardial approach. The Company is currently

focused on the treatment of ventricular arrhythmias with its purpose-built vCLAS Ventricular Ablation System, which is CE Marked, and

in May 2026 the Company submitted the results of the FULCRUM-VT pivotal study to support its PMA application to the FDA for the vCLAS

Ventricular Ablation System. The Company is also developing a next-generation vCLAS Ultra catheter, designed to support faster

ablation procedures with a smaller and more flexible form factor than its predecessor vCLAS device.

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 trial, which has fully enrolled 209 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. FULCRUM-VT 6-month primary

chronic effectiveness was defined as freedom from sustained monomorphic VT lasting longer than 30 seconds or VT requiring appropriate

ICD device therapy, in the absence of new or increase in antiarrhythmic drug therapy beyond previously failed dose.

The FDA has granted Investigational Device Exemption

(IDE) approval to expand the Company’s FULCRUM-VT trial to evaluate the safety and effectiveness of the Company’s next-generation

vCLAS Ultra catheter for the treatment of Sustained Monomorphic Ventricular Tachycardia (SMVT).

Adagio’s

vCLAS™ Ventricular Ablation System is commercially available for the treatment of monomorphic

VT in Europe and select other geographies but is limited to investigational use in the United States.
