Price checks use the past 12 months to June 2026. Some use the latest annual report instead, as marked. Quality checks use five annual reports, the latest for the year to December 2025.

Cash flow or capital spending isn't reported, so free cash flow is unknown.

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 3 Aug 2026 and 8 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.

  • We may not realize the anticipated benefits of our stock repurchase program, and the timing and level of shares of our common stock repurchased may have an adverse impact.

    Could happen
    The existence of the repurchase program could cause the price of our common stock to be higher than it otherwise would be and potentially reduce the market liquidity for our common stock. Further, we cannot guarantee that any purchases under the repurchase program will enhance long-term stockholder value. For example, the price of our common stock may decline below the levels at which we purchase such shares, and short-term fluctuations in the price of our common stock could reduce the effectiveness of the repurchase program. Purchasing shares of our common stock under the repurchase program will also reduce the amount of cash we have available to fund capital expenditures, investments in strategic initiatives, other operating requirements, and further share repurchases, and we may fail to realize the anticipated benefits of the repurchase program.

  • New governmental regulations and/or changes in existing governmental regulations, or in the way such regulations are interpreted or enforced, could have a material adverse effect on the Company.

    Could happen
    The CFPB has also focused on consumer data access, including through its final rule implementing Section 1033 of the Dodd-Frank Wall Street Reform and Consumer Protection Act, commonly referred to as the “open banking” rule to empower consumers and authorized third parties to access account data controlled by financial institutions. Open banking rulemaking has long been expected to have a significant impact on both financial institutions and third parties. The scope, timing, and compliance obligations associated with the open banking rule are subject to ongoing litigation, and the rule may be revised or replaced through further rulemaking, which could create regulatory uncertainty and require us to make additional operational, technology, and compliance investments. In fact, the CFPB has issued an advanced notice of proposed rulemaking soliciting public comment to reconsider the implementation of Section 1033 of the open banking rule. This signals a further shift in regulatory expectations for consumer-authorized data sharing, and further clouds the degree of compliance burden on covered entities. Decreases in federal supervisory activities in selected areas may result in a corresponding increase in state supervisory and enforcement activities in those or other areas. The degree and scope of state regulation remains to be seen.

  • We may be subject to lending risks and risks associated with loan portfolio concentrations, which could adversely affect the Company.

    Already happened
    Deterioration in economic conditions or in the real estate market could result in increased delinquencies and foreclosures and could have an adverse effect on the collateral value for many of these loans and on the repayment ability of many of our borrowers. Deterioration in economic conditions or in the real estate market could also reduce the number of loans we make to businesses in the construction and real estate industry, which could negatively impact our interest income and results of operations. For example, in 2025, we experienced slower lease-up in our commercial real estate multi-family portfolio, which contributed to an increase in criticized assets in the middle of 2025 before improving later in the year. More recently, we have experienced weaker than anticipated loan production, including muted demand for certain commercial real estate and construction lending and softer new construction activity in several of our markets. If these conditions persist or we are unable to generate sufficient new loan production to offset ongoing runoff, amortization and payoffs, our loan balances may decline. If economic conditions or the real estate market deteriorate, or if any of the foregoing trends persist or worsen, we could experience higher levels of criticized and nonperforming assets, increased net charge-offs and provisions for credit losses, and reduced profitability, any of which could have a material adverse effect on our business, financial condition and results of operations. Similarly, the occurrence of a natural or man-made disaster in our market areas could impair the value of the collateral we hold for real estate secured loans. Any factor or combination of factors identified above could negatively impact our business, financial condition, and results of operations.

  • We may be subject to lending risks and risks associated with loan portfolio concentrations, which could adversely affect the Company.

    Already happened
    In addition, many of our borrowers operate in industries that are directly or indirectly impacted by changes in commodity prices, such as agriculture and livestock businesses, as well as businesses indirectly impacted by commodities prices, such as businesses that transport commodities or manufacture equipment used in production of commodities. Changes in commodity products prices depend on local, regional, and global events or conditions that affect supply and demand for the relevant commodity. For example, in 2025 we experienced increased credit stress in certain of our grain credit relationships as lower commodity prices and elevated input costs pressured borrower cash flows. If such conditions persist or recur, we could experience higher criticized or nonperforming loans and increased credit losses in these portfolios.

  • We may not realize the anticipated benefits of our stock repurchase program, and the timing and level of shares of our common stock repurchased may have an adverse impact.

    Could happen
    The timing and amount of any purchases under the repurchase program will depend on a number of factors, such as the price of our common stock, economic and market conditions, the availability of alternative investment opportunities, our liquidity, corporate and regulatory requirements, and other factors deemed appropriate. If we do not purchase shares of our common stock under the repurchase program, our reputation, investor confidence, and the price of our common stock may be adversely impacted.
