Warning signs in its filings

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

1 serious warning sign in Inmune Bio’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 30 Mar 2026, plus the 10-Q filed 6 Aug 2026 and 8 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 conditions and events raise substantial doubt about the Company’s ability to continue as a going concern.”
    Show the full paragraph
    The Company has incurred significant losses and negative cash flows from operations since inception and expects to incur additional losses until such time that it can generate significant revenue from the commercialization of its product candidates. During the six months ended June 30, 2026, the Company incurred a net loss of $ 6.7 million and had net cash flows used in operating activities of $ 6.6 million. Given the Company’s projected operating requirements and its existing cash and cash equivalents, the Company is projecting insufficient liquidity to sustain its operations through one year following the date that the financial statements are issued. These conditions and events raise substantial doubt about the Company’s ability to continue as a going concern.

    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.
