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 warning signs we check for were found.

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 9 Sep 2026 and 8 later 8-Ks.

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

Cheap for a reason is the question the numbers cannot answer.

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

What changed in the risks this year

Companies must list what could hurt them each year. These are the parts that changed since last year’s report.

  • Acquisitions and other strategic transactions involve a number of inherent risks, any of which could result in the benefits anticipated not being realized.

    Could happen
    We may elect to divest certain assets or part of our business that do not align with our strategic direction. A divestiture could result in the decrease in net sales and net income in future periods. In addition, there are no assurances that we will receive a fair value that meets the expectations of shareholders in conjunction with a divestiture. In connection with any divestitures, we may incur liabilities for breaches of representations and warranties or failure to comply with operating covenants under any agreement for a divestiture. In addition, we may indemnify a counterparty in a divestiture for certain liabilities of the subsidiary or operations subject to the divestiture transaction. These liabilities, if they materialize, could have a material adverse effect on our business or financial condition.

  • Our competitive environment may be impacted by technological innovation and we may be required to invest in technology to maintain our position in the industry.

    Could happen
    To sustain and improve our competitive position, we are continually evaluating and investing in technology that can enhance our customer experience and minimize our cost structure. The design, development, and implementation of new technology and systems carries inherent risks. For example, the development and implementation of such technology and systems may distract management from operations or result in operational inefficiencies or other unforeseen complications that may adversely affect our business operations and customer relationships. We may not realize the anticipated benefits associated with certain investments in technology and systems and may be required to record material non-cash impairment charges. However, failure to develop such technology, not being first to market or not having industry leading features relative to others in our industry could put us at a competitive disadvantage. Any of these developments could have a material adverse impact our business, financial position and results of operations.

Read it in the annual report

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
  • Every number footnoted to the filing it came from

It's near its lowest price in a year. The deep dive tells you if that's a bargain or a warning.
