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 24 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.

  • Increased demand for semiconductors and electronic components driven by artificial intelligence ("AI") infrastructure and data center expansion could adversely affect our supply chain and operating results.

    The rapid growth of AI applications and the expansion of large-scale data centers have significantly increased global demand for semiconductors, processors, memory devices, power management components and other electronic parts. As a result, component manufacturers may prioritize production capacity for higher-volume or higher-margin customers serving AI, cloud computing and hyperscale data center markets.

  • Increased demand for semiconductors and electronic components driven by artificial intelligence ("AI") infrastructure and data center expansion could adversely affect our supply chain and operating results.

    Could happen
    ​ The impact of these risks may be amplified by geopolitical tensions, trade restrictions, manufacturing concentration in certain regions, transportation disruptions or continued growth in AI-related demand for advanced and legacy semiconductor products.
  • Increased demand for semiconductors and electronic components driven by artificial intelligence ("AI") infrastructure and data center expansion could adversely affect our supply chain and operating results.

    Could happen
    We rely on a variety of third-party suppliers for critical electronic components used in our products. Increased competition for available semiconductor capacity could result in extended lead times, reduced allocations, higher prices, supply shortages and less favorable purchasing terms. In addition, shortages affecting a single component may delay the production and shipment of finished products, even when other materials remain available.

  • Changes in U.S. policies, including tariffs may adversely affect our business, financial condition, and results of operations. Tariff decisions in the current environment has become difficult to predict.

    Could happen
    We source certain raw materials, components, and finished goods from international suppliers and are therefore exposed to changes in U.S. trade policy. In recent years, the United States has imposed, modified, suspended, or terminated tariffs under various statutory authorities, including IEEPA, Section 122, and Section 301. These actions have been subject to significant legal, political, and regulatory uncertainty, including court challenges and subsequent replacement tariffs. Recent developments have included judicial rulings concerning the legality of certain IEEPA-based tariffs and the implementation of alternative tariff programs under Section 122 and Section 301 authorities.

  • Changes in U.S. policies, including tariffs may adversely affect our business, financial condition, and results of operations. Tariff decisions in the current environment has become difficult to predict.

    Could happen
    Future tariff actions, retaliatory trade measures, changes in tariff rates, expansion of tariff coverage, or modifications to applicable exemptions could increase our costs of goods sold, reduce profit margins, disrupt our supply chain, and negatively impact demand for our products. Although certain tariffs imposed under IEEPA have been invalidated by courts and may be subject to refund claims, replacement tariffs imposed under Section 122, Section 301, or other trade authorities may continue, expand, or be modified. The ultimate scope, duration, and economic impact of these measures remain uncertain and could adversely affect our sourcing costs, supply chain stability, and operating results. In addition, uncertainty regarding future trade policy may adversely affect purchasing decisions by customers, availability of suppliers, ocean freight capacity, and inventory planning.
