Warning signs in its filings

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

1 serious warning sign in Cardiff Oncology’s 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 24 Feb 2026, plus the 10-Q filed 11 Aug 2026 and 11 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.

    “Management has performed an analysis and concluded that there exists a substantial doubt about the Company's ability to continue as a going concern.”
    Show the full paragraph
    The Company has incurred net losses since its inception and has negative operating cash flows. As of June 30, 2026, the Company had $ 34.5 million in cash, cash equivalents and short-term investments, which is not sufficient to meet its funding requirements for at least the next 12 months following the filing of this Form 10-Q. Management has performed an analysis and concluded that there exists a substantial doubt about the Company's ability to continue as a going concern. The accompanying financial statements have been prepared on a going concern basis, which contemplates the realization of assets and satisfaction of liabilities in the normal course of business. The financial statements do not include any adjustments related to the recoverability and classification of recorded asset amounts or the amounts and classification of liabilities that might result from the outcome of this uncertainty.

    From the 10-Q filed 11 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.
