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 26 Feb 2026, plus the 10-Q filed 30 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.

  • Conflicts around the world may have an adverse impact on our business. Current conflicts around the world, including those in Ukraine and the Middle East or tensions in the Taiwan Strait and South China Sea, and related sanctions could damage or disrupt international commerce and the global economy. We monitor the impacts of current conflicts on all aspects of our business, including how they may impact our employees, customers, supply chain, and distribution network. Impacts include financial and commodity volatility in raw material and other input costs and availability, as well as volatility in the financial markets. The severity of impacts on the global economy and our business, results of operations, financial position and cash flows remain unknown.

    Could happen
    We may also face increased competition from competitors that are employing AI and related technologies, some of whom may discover approaches that prove to be more effective use cases resulting in competitive advantage either commercially or through improved cost structure. In addition, uncertainties surrounding legal and regulatory requirements may require significant resources to support and maintain business practices compliant with laws concerning the use of AI and related technologies, the nature of which cannot be determined at this time.

  • The success of our business is affected by general and local economic conditions, and our business may be adversely affected by an economic slowdown or recession, or an inability of our pricing to keep pace with inflation of input costs. We are subject to national and regional economic conditions. These conditions include, but are not limited to, recession, inflation, interest rates, unemployment levels, the state of the housing market, and gasoline prices. These conditions and the economy in general could be affected by significant national or international events such as a global health crisis, acts of terrorism, or acts of war.

    Could happen
    We acquired Boughton on February 23, 2026. The success of this acquisition depends, in part, on our ability to successfully integrate this business with our current operations and to realize the anticipated benefits, including synergies, from the acquisition. There are a number of challenges and risks involved in our ability to successfully integrate Boughton with our current business and to realize the anticipated benefits of this acquisition, including all of the risks identified in the previous paragraph. Any of these factors could adversely affect our business, financial condition, results of operations, or cash flows.
