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 21 Aug 2026, and no 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.
U.S. budgeting process disruptions could reduce government spending, which could adversely impact our revenues, earnings, cash flows and financial condition. Funding for U.S. federal Government activities takes place on an annual basis with the Government fiscal year beginning on October 1 and ending on September 30. In recent years, the budgeting process has often not been completed by October 1st, which has required the temporary extension of funding authority. This in turn can and has resulted in temporary Government shutdowns, causing delays in procurements and contract awards. Because the provision of appropriated funds is undertaken on an annual basis and subject to budgetary rules and requirements, there can be disruptions to federal funding of current and future procurements.
of the SAFETY Act application process has and may in the future continue to result in coverage limitations for our products and services. If we fail to maintain SAFETY Act protections for each of our product models, options, offerings, software and services, or fail to apply in a timely way for coverage for new products, models, and services as we acquire or introduce them, or if the U.S. Department of Homeland Security limits the scope of any coverage previously awarded to us, denies us coverage or continued coverage for a particular product, product line, model, option, offering, software feature, or service, or delays in making decisions about whether to grant us coverage, we may become exposed to legal claims that the SAFETY Act was otherwise designed to prevent. Moreover, the SAFETY Act was not designed to shield providers of qualified anti-terrorism products and services from all types of claims that may arise from acts of terrorism, including from many types of claims lodged in courts outside of the United States or acts of terrorism that occur outside of the United States, which exposes us to legal claims and litigation defense costs despite the SAFETY Act awards we have received.

Could happenWe also rely on third-party logistics providers and carriers that operate in or near affected regions. Any disruption to their operations—including port closures, airspace restrictions, or rerouting of vessels—could materially affect our delivery timelines and cost structure. Because the duration and outcome of the conflict are uncertain, we may experience additional unforeseen impacts. Any of these factors, individually or collectively, could materially and adversely affect our business, financial condition, and results of operations.

Could happenIn addition, regulators, including the European Union and the State of California, have adopted, or are considering adopting, regulations regarding ESG matters, including, but not limited to, climate change-related matters. Such regulatory approaches are not uniform, which may increase the cost and complexity of compliance. Addressing stakeholder expectations, including regulations, entails costs and any failure to successfully navigate such expectations may result in reputational harm, loss of customers or contracts, potential regulatory or investor engagement, or other adverse impacts to our business.
