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 27 Feb 2026, plus the 10-Q filed 6 Aug 2026 and 3 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 are subject to cyber security risks and may incur increasing costs in efforts to minimize those risks and to comply with regulatory standards.

    Could happen
    We strive to comply with all applicable laws, policies, legal obligations and industry codes of conduct relating to privacy and data protection. However, we continue to see increasingly complex, rigorous and more stringent regulatory standards enacted to protect businesses and personal data. In the United States, we are subject to the California Consumer Privacy Act, as amended by the California Privacy Rights Act (collectively, “CCPA”), which grants California residents significant rights over their personal information and imposes substantial compliance obligations on covered businesses. Numerous other states—including Virginia, Colorado, Connecticut, Texas, Oregon, Montana, Delaware, Indiana, Iowa, Tennessee and others—have enacted comprehensive privacy laws with varying requirements, and additional states continue to consider similar legislation. This patchwork of state laws creates compliance complexity and increases the risk of inadvertent violations. Certain state laws, including the CCPA, provide for statutory damages and private rights of action in connection with data breaches, which could expose us to significant liability. Internationally, we are subject to the European Union's General Data Protection Regulation (“GDPR”), the UK GDPR and other data protection regimes that impose strict requirements on the processing of personal data and provide for substantial fines for non-compliance. Cross-border data transfers are subject to evolving legal requirements, and mechanisms we rely on to transfer data internationally may be challenged or invalidated, which could disrupt our operations or require us to implement costly alternative arrangements. Any failure to comply with GDPR, the CCPA, or other domestic or international regulatory standards, could subject the Company to legal and reputational risks. Misuse of or failure to secure personal information could also result in violation of data privacy laws and regulations, proceedings against us by governmental entities or others, damage to our reputation and credibility, and could have a material adverse effect on our business and results of operations.

  • Product liability claims and litigation could affect our business, reputation, financial condition, results of operations and cash flows.

    Could happen
    We also face product liability exposure when our products are incorporated into residential construction by home builders. When home builders are sued for construction-related claims, including claims alleging defective construction, water intrusion, structural failures or building code violations, they may seek indemnification or contribution from us as a product supplier, or plaintiffs may name us directly as a defendant. These claims may arise years after our products were sold and installed, and may involve multiple parties, complex allocation disputes and protracted litigation. Construction defect litigation is common in certain jurisdictions and can result in significant defense costs and potential liability, regardless of whether our products were the proximate cause of the alleged damage.

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.
