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 Feb 2026, plus the 10-Q filed 29 Jul 2026 and 5 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 be unable to successfully acquire and integrate other businesses.

    Could happen
    In addition, we have made, and in the future may make, acquisitions through joint ventures. Joint ventures inherently involve a lesser degree of control over the business operations acquired. Our joint venture partners may have economic and business interests that are inconsistent with ours and disputes between us and our joint venture partners could subject us to delays, litigation and increased expenses related to acquired businesses.

  • Prices for the products we purchase and the costs to operate our business are subject to significant volatility and external market variables beyond our control, and we may be unable to adjust our pricing or cost structure quickly enough to avoid the adverse effects on our financial performance.

    Already happened
    Additionally, trade policies and related government actions, including the imposition, increase, or extension of tariffs on goods imported into the United States, can further amplify price volatility and result in supplier price increases (such as the lighting and irrigation product price increases we experienced during the 2025 Fiscal Year). There remains significant uncertainty regarding the extent, duration, and economic impact of any future tariffs or other trade measures. Price changes associated with such policies can occur rapidly, and we might not be successful in adjusting our prices to reflect increases in our costs.

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
