Warning signs in its filings

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

1 serious warning sign in BioCardia’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 Mar 2026, plus the 10-Q filed 12 Aug 2026 and 19 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 beyond one year from the date these financial statements are issued.”
    Show the full paragraph
    We have incurred net losses and negative cash flows from operations since our inception and had an accumulated deficit of approximately $ 172.2 million as of June 30, 2026. Management expects operating losses and negative cash flows to continue through the next several years. We expect to incur increasing costs as we advance our trials and development activities. Therefore, absent additional funding, management believes our cash and cash equivalents of approximately $ 4.1 million as of June 30, 2026 are not sufficient to fund our planned expenditures and meet our obligations beyond January 2027. These factors raise substantial doubt about our ability to continue as a going concern beyond one year from the date these financial statements are issued. The financial statements do not include any adjustments that might result from the outcome of this uncertainty.

    From the 10-Q filed 12 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.
