Warning signs in its filings

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

None of the serious warning signs we check for were found. 1 thing worth knowing.

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 6 Mar 2026, plus the 10-Q filed 6 Aug 2026 and 7 later 8-Ks.

  • One big customer

    Worth knowing

    One customer brings in a big share of sales: 66% last year. Losing that customer would hurt.

    “The Company had three customers who individually accounted for 66 %, 11 %, and 10 % of total revenues for the year ended December 31, 2025 and two customers who individually accounted for 61 % and 12 % of total revenues for the year ended December 31, 2024.”

    From the 10-K filed 6 March 2026, Item 8. Financial Statements and Notes. 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.
