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 27 Feb 2026, plus the 10-Q filed 31 Jul 2026 and 5 later 8-Ks.

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.

• We may not be able to successfully integrate the business of Eastern Michigan Financial Corporation

  Could happen

  The integration of the acquired operations will require significant time and attention from our management team The process of integrating Eastern Michigan Financial Corporation and its subsidiaries involves significant efforts and resources from our management and employees. These integration activities include aligning systems, procedures, and personnel, as well as harmonizing corporate cultures and business practices. As a result, our management team and staff may be required to devote substantial time and attention to integration matters, which could detract from their ability to focus on the day-to-day management and operation of our business. This diversion of resources and attention may result in missed business opportunities, reduced productivity, or delays in responding to market developments and customer needs. In addition, integration efforts may create uncertainty or dissatisfaction among customers, employees, or other stakeholders, which could negatively impact our relationships and retention rates. If the integration process is not managed effectively, or if unforeseen challenges arise, our business, financial condition, and results of operations could be materially and adversely affected.

• We are in the process of converting our core processing system

  Could happen

  We have initiated the transfer of our core processing system to Jack Henry & Associates, the core processor used by Eastern Michigan Financial Corporation and Eastern Michigan Bank. This conversion is a complex and resource-intensive project that is not expected to be completed until the first quarter of 2027. During this period, we may encounter operational challenges, including potential disruptions to daily banking activities, data migration errors, or delays in integrating systems and processes. There is also a risk of temporary interruptions in customer service or inadvertent disclosure of sensitive customer information as a result of the system conversion. Any such disruptions or errors could negatively impact customer relationships, cause reputational harm, and result in additional costs. Moreover, the successful completion of the conversion depends on the effective coordination of our personnel, vendors, and third-party service providers. Failure to complete the core processing system conversion in a timely and efficient manner, or to realize the anticipated benefits of the new system, could adversely affect our business, financial condition, and results of operations.

• We have incurred indebtedness in connection with the acquisition

  Could happen

  We entered into a credit agreement with U.S. Bank National Association for a $30 million term loan to fund a portion of the purchase price and related expenses of the acquisition. This senior indebtedness requires us to dedicate a portion of our cash flows to debt service payments, which reduces the funds available for other operational needs, capital expenditures, and strategic opportunities. This increased debt level also makes us more vulnerable to adverse changes in general economic, industry, or competitive conditions, and exposes us to the risk of rising interest rates since the indebtedness bears variable interest. Furthermore, our indebtedness may limit our flexibility in responding to changes in our business environment and could place us at a competitive disadvantage compared to other companies with less debt. It may also restrict our ability to obtain additional financing on favorable terms, or at all, should the need arise. Our ability to meet our debt obligations will depend on our future performance, which is subject to a range of factors, including general economic, regulatory, and competitive conditions, many of which are beyond our control. If we are unable to generate sufficient cash flow to service our debt or to refinance our indebtedness as it matures, our business, financial condition, and results of operations could be materially and adversely affected.

• We may not be able to successfully integrate the business of Eastern Michigan Financial Corporation

  Could happen

  The success of the acquisition of Eastern Michigan Financial Corporation completed on December 31, 2025 depends, in part, on our ability to successfully integrate the operations, systems, and personnel of the acquired business with our own. The integration process may involve operational complexities, potential customer confusion or dissatisfaction, technology and system modifications, and the risk of service interruptions. There is no assurance that the integration process, including the core processor transition, alignment of debit card programs, and alignment of employee benefit programs, will proceed as planned or that we will achieve the anticipated benefits and synergies of the acquisition. Unanticipated issues, delays, or costs may arise, and we may encounter obstacles that could prevent us from realizing the expected advantages of the transaction. If we are unable to effectively integrate the acquired business, our business, financial condition, and results of operations could be materially and adversely affected.

• Our credit losses could increase and our allowance may not be adequate to cover actual loan losses.

  Could happen

  of our loan portfolio and provide an allowance for credit losses based on several factors. If our assumptions are wrong, our allowance may not be sufficient to cover our losses, which would have an adverse effect on our operating results. The actual amounts of future provisions for credit losses cannot be determined at this time and may exceed the amounts of past provisions. Any increase in the allowance for credit losses on loans, securities and/or off-balance sheet credit exposures will result in a decrease in net income and, possibly, capital, and may have a material adverse effect on our business, financial condition and results of operations.
