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 11 Aug 2026 and 9 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.

  • We may use artificial intelligence, machine learning, data science and similar technologies in our business, and challenges with properly managing such technologies could result in reputational harm, competitive harm, and legal liability, and adversely affect our business, financial condition and results of operations.

    Could happen
    Artificial intelligence, machine learning, data science and similar technologies (collectively, “AI”), including third-party AI tools, may be enabled by, or integrated into, some of our business processes and solutions. As with many developing technologies, AI presents risks and challenges that could affect its further development, adoption, and use, and therefore our business. AI algorithms may be flawed or biased. Datasets used to train or develop AI systems may be insufficient, of inferior quality, or contain biased, incorrect or incomplete information. The utilization of AI may increase our risk and liability exposure relating to confidentiality, intellectual property infringement, and client use restrictions. Our AI governance review process and safeguards may not be adequate to protect against these risks and challenges.

  • We may use artificial intelligence, machine learning, data science and similar technologies in our business, and challenges with properly managing such technologies could result in reputational harm, competitive harm, and legal liability, and adversely affect our business, financial condition and results of operations.

    Could happen
    Our competitors or other third parties may incorporate AI into their product and service offerings more quickly or more successfully than us, which could impair our ability to compete effectively and adversely affect our business, financial condition and results of operations.
  • Our operations worldwide expose us to legal, political and economic risks in different countries as well as currency exchange rate fluctuations and impacts from inflation that could harm our business and financial results.

    • the ongoing conflict between Russia and Ukraine, which has resulted in the imposition by the U.S. and other nations of restrictive actions against Russia, Belarus and certain banks, companies and individuals;
  • We may use artificial intelligence, machine learning, data science and similar technologies in our business, and challenges with properly managing such technologies could result in reputational harm, competitive harm, and legal liability, and adversely affect our business, financial condition and results of operations.

    Could happen
    Additionally, the laws and regulations concerning the use of AI continue to evolve. If the use or integration of AI systems, or the outputs generated by such systems, were determined to be non-compliant (e.g., in relation to AI statutory regimes, data privacy rights or in relation to the use of AI for certain activities or use cases), this may expose us to regulatory action or litigation. It is possible that emerging regulations or changes to intellectual property laws may limit or block the use of AI in our business or otherwise impose restrictions that may adversely affect the efficiency of our business processes or solutions that were utilizing AI technologies.

  • Our charter documents contain provisions that may delay, defer or prevent a change of control.

    Could happen
    • vesting of exclusive authority in our Board of Directors to determine the size of the board and to fill vacancies; and • advance notice requirements for stockholder proposals and nominations for election to our Board of Directors.

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.
