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 23 Feb 2026, plus the 10-Q filed 31 Jul 2026 and 8 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.

• The development and use of AI presents risks and challenges that may adversely impact our business

  Could happen

  AI models, particularly generative or agentic AI models, may produce outputs or take action that is incorrect, that reflects biases included in the data on which they are trained, that results in the release of private, confidential, or proprietary information, that infringes on the intellectual property rights of others, or that is otherwise harmful. In addition, the complexity of many AI models makes it difficult to understand why they are generating particular outputs. This limited transparency increases the challenges associated with assessing the proper operation of AI models, understanding and monitoring the capabilities of the AI models, reducing erroneous output, eliminating bias, and complying with regulations that require documentation or explanation of the basis on which decisions are made. Further, we may rely on AI models developed by third parties, and, to that extent, would be dependent in part on the manner in which those third parties develop and train their models, including risks arising from the inclusion of any unauthorized material in the training data for their models and the effectiveness of the steps these third parties have taken to limit the risks associated with output of their models, matters over which we may have limited visibility. Any of these risks could expose us to liability or adverse legal or regulatory consequences and harm our reputation and the public perception of our business or the effectiveness of our security measures.

• The development and use of AI presents risks and challenges that may adversely impact our business

  Could happen

  We or our third-party (or fourth-party) vendors, customers or counterparties develop or incorporate AI technology in certain business processes, services or products. The development and use of AI presents a number of risks and challenges, including concerns around safety and soundness, privacy and data-handling, fair access to financial services, fair treatment to customers, inaccuracy of results broadly known as “hallucinations” and compliance with applicable laws and regulations. The legal and regulatory environment relating to AI is uncertain and rapidly evolving, both in the U.S. and internationally, and includes regulatory schemes targeted specifically at AI as well as provisions in intellectual property, privacy, consumer protection, employment, and other laws applicable to the use of AI. These evolving laws and regulations could require changes in our implementation of AI technology and increase our compliance costs and the risks to us of non-compliance.

• Our loan portfolio contains concentrations in certain business lines or product types that have unique risk characteristics and may expose us to increased lending risks.

  Already happened

  We also extend credit to certain NDFIs, which provide services similar to traditional banks but do not accept deposits from the general public and are not regulated by federal or state banking agencies. Banks that extend credit to NDFIs may be less likely to detect fraud, whether committed by the NDFI or by an underlying borrower, pledgor or guarantor of the NDFI, or other underlying credit issues, than for loans to traditional commercial borrowers, due to the lack of a direct relationship between the bank and the third parties and collateral underlying the loan. We experienced potential fraud in connection with an extension of credit to an NDFI in the third quarter of 2025 that resulted in the establishment of a $29.6 million specific reserve, as discussed in more detail in Recent Developments within Item 7 of this Form 10-K. Approximately $14.7 billion, or 25.0% of our total HFI loans are loans to NDFIs. While we carefully underwrite and monitor extensions of credit to NDFIs in accordance with our policies, any undetected fraud or underlying credit issues could have a material adverse impact on our financial conditions and results of operations.

• The price of our common stock may fluctuate significantly in the future, which could result in losses to our investors and litigation against us.

  Could happen

  • actions of activist stockholders could impact the pursuit of our business strategies, cause us to incur substantial costs, and divert management's and the Board's attention and resources;

• Regulatory compliance requirements and expense likely will increase when we reach $100 billion in assets.

  Could happen

  Regulatory requirements and associated costs generally increase based on a bank holding company’s consolidated asset tier. Upon exceeding the $100 billion in assets threshold, we will become subject to Category IV enhanced prudential standards. As of December 31, 2025, we had $92.8 billion in assets on a consolidated basis. Under such enhanced prudential standards, Category IV bank holding companies are subject to greater regulation and supervision, including, but not limited to: certain capital planning and stress testing and capital buffer requirements; supervisory capital stress testing conducted by the FRB biennially; and certain liquidity risk management and liquidity stress testing and buffer requirements. Our preparations for, and the application of, these enhanced prudential standards and resolution planning requirements for our depository institution could adversely affect our results of operations and financial performance through additional capital and liquidity requirements and increased compliance costs. While compliance costs associated with those and other Category IV regulations are expected to be substantial, we believe a considerable portion of these costs have already been incurred as we have proactively upgraded compliance systems, processes, and staffing in anticipation of surpassing the $100 billion asset mark.
