From Form 4 filings: insiders must report trades in their own company's shares within two days.

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 20 Feb 2026, plus the 10-Q filed 5 Aug 2026 and 3 later 8-Ks.

  • One big customer

    Worth knowing

    One customer brings in a big share of sales: 70% last year. Losing that customer would hurt.

    “In 2025, one end customer represented more than 70% of our revenue; the top three end customers represented an aggregate of approximately 86% of our revenue.”

    From the 10-K filed 20 February 2026, Item 1A. Risk Factors. 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.

What could go wrong

  • Its accounts show patterns that sometimes come before companies have to correct past results (Beneish score).
  • It isn't cheap on profits: 246.9× operating profit.

Whether the price already reflects the risks is what the deep dive is for.

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.

  • What the business is worth, as a range, and the margin of safety at today’s price
  • Prices to start buying, buy, and buy hard
  • The three things that would make this a mistake
