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 19 Nov 2025, plus the 10-Q filed 6 Aug 2026 and 7 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.

  • Challenges and uncertainties with respect to the development, deployment and use of artificial intelligence (“AI”) in our business and products, services and solutions may result in reputational harm, competitive disadvantages and adverse impacts to our operations, business and financial results.

    Could happen
    We are in the initial stages of incorporating AI into our operations and our products, services and solutions. AI presents risks and challenges that could adversely impact our business. AI, especially during the early stages of the development and use, carries inherent risks with no guarantee that AI will enhance or improve our operations, products, services or solutions. Ineffective or inadequate AI development or deployment practices could result in unintended consequences. Any disruption, malfunction or failure in AI functionality could result in delays in production, use or sale of our products, services and solutions and adversely affect our business and reputation.

  • Challenges and uncertainties with respect to the development, deployment and use of artificial intelligence (“AI”) in our business and products, services and solutions may result in reputational harm, competitive disadvantages and adverse impacts to our operations, business and financial results.

    Could happen
    Further, we face risks of competitive disadvantage if our competitors more effectively leverage AI to drive operational efficiencies, create new or enhanced products, services and solutions or otherwise disrupt the marketplace. Failure to effectively develop, implement, use and manage AI may negatively impact our ability to compete, reduce revenue and adversely impact our business.

  • Challenges and uncertainties with respect to the development, deployment and use of artificial intelligence (“AI”) in our business and products, services and solutions may result in reputational harm, competitive disadvantages and adverse impacts to our operations, business and financial results.

    Could happen
    Our vendors, suppliers and third-party providers may incorporate AI into their offerings with or without disclosing this use to us. These third-parties may not meet existing or rapidly evolving regulatory or industry standards related to privacy and data protection, or such AI use may result in unintended consequences related to our operations, products, services and solutions, any of which may adversely impact our reputation, operations, products, services, solutions and overall business. Further, threat actors may continue to develop and use AI to engage in illegal activities, including cyberattacks, to access, steal or misuse personal data, confidential information and intellectual property. Any of these uses of AI could damage our reputation, result in the loss of valuable property and information and adversely impact our business.

  • Challenges and uncertainties with respect to the development, deployment and use of artificial intelligence (“AI”) in our business and products, services and solutions may result in reputational harm, competitive disadvantages and adverse impacts to our operations, business and financial results.

    Could happen
    The legal and regulatory environment landscape surrounding AI is uncertain and rapidly evolving, including the areas of intellectual property, cybersecurity and privacy and data protection. Compliance with new or changing laws, regulations or industry standards relating to AI may require significant investment and resources, and may limit our ability to develop, implement or use AI, which may result in reputational harm, legal liability or other adverse effects on our operations, products, services, solutions and overall business.

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
