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 2 Mar 2026, plus the 10-Q filed 4 Aug 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.

  • Climate change, including physical risks and the transition to lower-emission building practices, could increase our costs, disrupt operations, and adversely affect our financial results.

    Could happen
    While we may seek to recover some increased costs through pricing or contractual mechanisms, we may not be able to do so fully or on a timely basis due to competitive pressures, contractual limitations, or market conditions. If we are required to absorb higher costs or experience operational disruptions related to climate-related physical or transition risks, our profitability, results of operations, and cash flows could be materially and adversely affected.

  • A U.S. government shutdown or delays in federal appropriations could adversely affect our business and results of operations.

    Could happen
    In addition, our customers, suppliers, and partners may rely on government funding, approvals, or regulatory actions that may be suspended, delayed, or limited during a shutdown. These disruptions could postpone the start of projects, extend permitting timelines, or impact demand for our services. A prolonged or repeated government shutdown could also contribute to broader economic uncertainty, reduce public and private investment activity, and slow decision-making by our customers. There can be no assurance that government operations will continue without interruption, and any such disruptions could materially and adversely affect our financial condition, results of operations, liquidity, and overall business prospects.
    Read more
  • Delays in, disputes over, or defaults on customer payments could adversely affect our liquidity, results of operations, and financial condition.

    Could happen
    If customers delay payments, dispute amounts billed, experience financial difficulties, or default on their payment obligations, we may be unable to recover all costs incurred on affected projects, may be required to increase allowances for credit losses, or may experience reduced cash flows. Any such developments could materially and adversely affect our liquidity, financial position, results of operations, and cash flows.
    Read more
  • Unsatisfactory safety performance could subject us to penalties and/or litigation, restrict our ability to pursue certain projects, increase operating costs, and adversely affect our employees’ morale and retention.

    Could happen
    Poor safety performance could also damage our reputation, strain customer relationships, negatively impact our employees’ morale, and contribute to higher employee turnover. Any of these outcomes could materially and adversely affect our financial position, results of operations, cash flows, and long-term growth prospects.

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
