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 28 Sep 2026, and no later 8-Ks.

  • One big customer

    Worth knowing

    One customer brings in a big share of sales: 41% last year. Losing that customer would hurt.

    “During the fiscal year ending June 30, 2026, we sold products and services to 266 customers with one customer accounting for approximately 41% of total revenues and another customer accounting for 27% of our total revenues.”

    From the 10-K filed 28 September 2026, Item 1. Business. 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.
