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 12 Mar 2026, plus the 10-Q filed 6 Aug 2026 and 7 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.

    Could happen
    Changes in trade policies, including the imposition of tariffs or the escalation of a trade war, could negatively impact the economic conditions in the markets we serve. Our customers-particularly local businesses engaged in agriculture, manufacturing, and retail-may face higher costs for imported goods and materials, reduced export demand, and supply chain disruptions due to increased tariffs. These challenges could lead to lower revenues, reduced profitability, and potential layoffs, all of which may impair our customers’ ability to meet their financial obligations. Furthermore, prolonged trade tensions and economic uncertainty could lead to market volatility, declining asset values, and weakened consumer confidence. If our customers experience financial stress, we could see an increase in loan delinquencies and credit losses, negatively affecting our asset quality and overall financial performance. Additionally, any decline in local economic activity could reduce loan demand, deposit growth, and fee income, which are critical to our long-term success. While we actively monitor economic and policy developments, we cannot predict the outcome of trade negotiations or the full impact of tariffs and trade restrictions on our business, customers, and the broader economy. Any adverse effects from tariffs or a trade war could materially and negatively impact our financial condition, results of operations, and future growth prospects.

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.
