Warning signs in its filings

Problems the company itself reported to the SEC, in its own words.

2 serious warning signs in Adagio Medical Holdings’ filings.

We look for five warning signs: doubt it can keep going, weak checks on its own accounts, a notice that its past accounts can't be relied on, a change of auditor, and one customer bringing in a big share of sales. We don't check lawsuits, investigations or debt yet.

We checked the auditor's report, internal controls, restatement notices, auditor changes and big customers in the 10-K filed 27 Mar 2026, plus the 10-Q filed 11 Aug 2026 and 12 later 8-Ks.

  • Doubt it can keep going

    Serious

    The company or its auditor warned it may not have enough money to last the next year.

    “These factors raise substantial doubt about our ability to continue as a going concern for the twelve-month period from the date of this filing with the SEC.”
    Show the full paragraph
    As of the report date, we do not believe our existing cash and cash equivalents are sufficient to fund our operating and capital expenditure requirements for at least 12 months from the date of issuance of the audited consolidated financial statements included in this Report. Based on our current research and development plans, we expect to have sufficient resources to fund our planned operations into the fourth quarter of 2026. We have based this estimate on assumptions that may prove to be wrong, and we could exhaust our capital resources sooner than expected. No assurance can be given as to whether additional needed financing will be available on terms acceptable to us, if at all. If sufficient funds on acceptable terms are not available when needed, we may be required to suspend or forego certain planned activities. Failure to manage discretionary spending or raise additional financing, as needed, could adversely impact our ability to achieve our intended business objectives and may have an adverse effect on our results of operations and future prospects. These factors raise substantial doubt about our ability to continue as a going concern for the twelve-month period from the date of this filing with the SEC. Refer to Note 1 - Description of Organization and Business Operations in our condensed consolidated financial statements for additional information on the going concern assessment.

    From the 10-Q filed 11 August 2026, Part I, Item 2. Management's Discussion and Analysis. Read it in the filing

  • Its past accounts can't be relied on

    Serious

    It told the SEC its earlier accounts should no longer be relied on, usually because they contained errors.

    8-K Item 4.02 filed 1 Nov 2024: the company said its earlier financial statements should no longer be relied on.

    From an 8-K filed 1 November 2024: Previously issued accounts should no longer be relied on. Open the filing

A 10-K is the yearly report every US company files with the SEC. An 8-K is a short notice of a big event.

The deep dive

Everything above is arithmetic on public filings. The deep dive reads the last ten years of annual reports, the proxy statements, and the earnings calls, then argues the case the way Buffett, Klarman, and Hohn would, and checks every claim against the source.
