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 26 Feb 2026, plus the 10-Q filed 7 Aug 2026 and 11 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.

  • Oil and natural gas prices are volatile. Extended declines in oil and natural gas prices have adversely affected, and could in the future adversely affect, our business, financial position, results of operations and cash flow.

    Could happen
    • political and economic conditions, including embargoes, in oil-producing countries or affecting other oil-producing activity, including the effects of any changes to conditions in or impacting Venezuela;
  • Increased scrutiny and changing stakeholder expectations with respect to environmental, social and governance (“ESG”) matters may impact our business and expose us to additional risks.

    Could happen
    Companies across all industries continue to face increasing scrutiny from stakeholders related to their ESG and sustainability practices. Failure or a perception (whether or not valid) of failure to implement our ESG strategy or achieve sustainability goals we may set could damage our reputation, causing our investors or other stakeholders to lose confidence in our company, and negatively impact our operations. There can be no assurance that we will be able to accomplish any announced goals, initiatives, commitments or objectives related to our ESG strategy, as statements regarding the same reflect our current plans and aspirations and are not guarantees that we will be able to achieve them within the timelines we announce, or at all. We may determine in our discretion that it is not feasible or practical to implement or complete certain of our ESG goals, initiatives, policies or procedures based on cost, timing or other considerations. Our continuing efforts to research, establish, accomplish and accurately report on the implementation of our ESG strategy, including any ESG goals, may also create additional operational risks and expenses and expose us to reputational, legal and other risks. Moreover, while we create and publish voluntary disclosures regarding ESG matters from time to time, some of the statements in those voluntary disclosures may be based on hypothetical expectations and assumptions that may or may not be representative of current or actual risks or events or forecasts of expected risks or events, including the costs associated therewith. Such expectations and assumptions are necessarily uncertain and may be prone to error or subject to misinterpretation given the long timelines involved and the lack of an established single approach to identifying, measuring and reporting on many ESG matters. Relatedly, there is increasing focus by regulators, customers and other stakeholders on greenwashing issues and environmental marketing and sustainability-related claims. There can be no assurance that we will not be subject to greenwashing allegations or claims associated with the veracity of our environmental and sustainability-related claims, including any claims related to our emissions reductions initiatives or the sustainability practices of our operators, among other things, which could expose us to liabilities or require us to incur additional costs to adequately prepare disclosures or improve internal controls. There is also increasing focus on ESG and sustainability disclosure and regulation across various jurisdictions and exposure to any new regulatory and legal requirements may lead to increased operational costs and compliance burden for us. The occurrence of any of the foregoing could have a material adverse effect on our business and financial condition.

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.
