Warning signs in its filings

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

1 serious warning sign in Aquabounty Technologies’ 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 31 Mar 2026, plus the 10-Q filed 6 Aug 2026 and 5 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.

    “Limited operating assets, dependency on capital raising activities and cumulative net losses raises substantial doubt about the Company’s ability to continue as a going concern within one year after the date that the accompanying condensed consolidated financial statements are issued.”
    Show the full paragraph
    The Company’s ability to continue as a going concern is dependent upon its ability to raise additional capital, including its ability to sell assets to generate liquidity to fund ongoing operations, and there can be no assurance that such capital will be available in sufficient amounts, on a timely basis, or on terms acceptable to the Company, or at all. Limited operating assets, dependency on capital raising activities and cumulative net losses raises substantial doubt about the Company’s ability to continue as a going concern within one year after the date that the accompanying condensed consolidated financial statements are issued. The accompanying condensed consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business and do not include any adjustments that might result from the outcome of this uncertainty.

    From the 10-Q filed 6 August 2026, Part I, Item 1. Financial Statements. Read it in 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.
