Item 7.01 Regulation FD Disclosure Disclosure
Material non-public information disclosed under Regulation Fair Disclosure, often investor presentations or guidance.
Item 9.01 Financial Statements and Exhibits Exhibits
Financial statements, pro forma financial information, and exhibit attachments filed with this report.
Regulation FD Disclosure regulatory
"Item 7.01 Regulation FD Disclosure. On August 13, 2026, Adagio Medical Holdings, Inc."
Regulation FD disclosure requires public companies to share important, market-moving information with everyone at the same time instead of tipping off analysts or large investors first. Think of it as making sure all players on a field hear the same announcement simultaneously; that fairness helps investors trust that stock prices reflect the same information and reduces the risk of sudden, unfair trading advantages or regulatory penalties for selective leaks.
Emerging growth company regulatory
"Securities registered pursuant to Section 12(b) of the Act ... Emerging growth company x"
An emerging growth company is a recently public or smaller public firm that qualifies for temporary, lighter regulatory and disclosure rules to reduce the cost and effort of being public. For investors, it means the company may provide less historical financial detail and face fewer reporting requirements than larger firms, so it can grow more quickly but also carries higher uncertainty—like buying a promising early-stage product with fewer user reviews.
furnished and shall not be deemed "filed" regulatory
"The information presented in this Item 7.01 ... is being furnished and shall not be deemed "filed""

2 - CONFIDENTIAL - Forward Looking Statements This presentation contains forward-looking statements that involve substantial risks and uncertainties. All statements, other than statements of historical facts, contained in this presentation, including statements regarding the potential of our Proprietary Ultra Low Temperature Cryoablation technology, the durability and reproducibility of the clinical data from our FULCRUM-VT pivotal study, our research, development and regulatory plans, and our strategy, future operations, future financial position, future revenues, projected costs, prospects, plans and objectives of management, are forward-looking statements. The words “anticipate,” “believe,” “estimate,” “expect,” “intend,” “may,” “might,” “plan,” “predict,” “project,” “target,” “potential,” “will,” “would,” “could,” “should,” “continue,” and similar expressions are intended to identify forward-looking statements, although not all forward-looking statements contain these identifying words. These forward-looking statements speak only as of the date of this presentation and are subject to a number of known and unknown risks, assumptions, uncertainties, and other factors that may cause our actual results, levels of activity, performance, or achievements to be materially different from those expressed or implied by any forward-looking statements and which may be beyond our control. We caution you that these statements are based on a combination of facts and factors currently known and projections of the future, which are inherently uncertain. Factors that may cause actual results to differ materially from current expectations include, but are not limited to, the ability to implement business plans, forecasts and other expectations after the recently completed business combination, the outcome of any legal proceedings that may be instituted against us, the ability to recognize the anticipated benefits of the recently completed business combination, which may be affected by, among other things, competition, our ability to grow and manage growth profitability, and our ability to meet Nasdaq’s listing standards, risks that internal and external costs required for ongoing and planned activities may be higher than expected, which may cause us to use cash more quickly than we expect or change or curtail some of our plans, or both; risks that our expectations as to expenses, cash usage, and cash needs may prove not to be correct for other reasons such as changes in plans or actual events being different than our assumptions, our ability to achieve future financial targets, changes in our business or external market conditions, challenges inherent in developing, manufacturing, launching, marketing, and selling new products, interruptions or delays in the supply of components or materials for, or manufacturing of, our products, unanticipated increases in costs or expenses, continued or sustained budgetary, inflationary, or recessionary pressures, uncertainties in contractual relationships, reductions in research and development spending or changes in budget priorities by customers, uncertainties relating to our research and development activities, potential product performance and quality issues, and intellectual property risks. Risks regarding our business are described in detail in our Securities and Exchange Commission (“SEC”) filings, our Annual Report on Form 10-K for the year ended December 31, 2024, our Quarterly Report on Form 10-Q for the quarter ended March 31, 2025, and our other filings with the SEC, which are available on the SEC’s website at www.sec.gov. We may not actually achieve the plans, intentions or expectations disclosed in our forward-looking statements, and you should not place undue reliance on our forward-looking statements. Actual results or events could differ materially from the plans, intentions and expectations disclosed in the forward-looking statements we make. The forward-looking statements contained in this presentation reflect our current views with respect to future events, and we assume no obligation to update any forward-looking statements except as required by applicable law. Management's Estimates We have based our estimates of the total addressable market and growth forecasts on a number of internal and third-party estimates and resources, including, without limitation, third party reports and the experience of the management team across the industries. While we believe our assumptions and the data underlying our estimates are reasonable, these assumptions and estimates may not be correct and the conditions supporting such assumptions or estimates may change at any time, thereby reducing the predictive accuracy of these underlying factors. In addition, the novelty of the markets for our products may make our assumptions and estimates more uncertain. As a result, our estimates of the total addressable market and growth forecasts for our products are subject to significant uncertainty and may prove to be incorrect. If third-party or internally generated data prove to be inaccurate or we make errors in our assumptions based on that data, the total addressable market for our products may be smaller than we have estimated, our future growth opportunities and sales growth may be impaired, any of which could have a material adverse effect on our business, financial condition and results of operations. Industry and Market Data; Trademarks Certain information contained in the presentation relates to or is based on studies, publications, statistics and surveys from third-party sources, and on our own internal estimates and research. In addition, all of the market data included in this presentation involves a number of assumptions and limitations, and there can be no guarantee as to the accuracy or reliability of such assumptions. While we believe that the third-party sources and our internal research are reliable, such sources and research have not been verified by any independent source. Any data on past performance or modeling contained herein is not an indication as to future performance. This information involves many assumptions and limitations, and you are cautioned not to give undue weight to such industry and market data. The information contained in the third-party citations referenced in this presentation is not incorporated by reference into this presentation. This presentation may include trademarks, service marks, trade names and copyrights of other companies, which are the property of their respective owners. The inclusion of particular trademarks, service marks, trade names and copyrights of other companies is not intended to, and does not, imply a relationship with us or our endorsement or sponsorship.
