Risk factors and legal proceedings
The risks OLD SECOND BANCORP INC names in Item 1A of its 10-K filed Feb 26, 2026: 49 risks under these headings, as written.6
- Risks Related to Economic Conditions
- Our business may be adversely affected by economic conditions.
- Inflationary pressures present a potential threat to our results of operation and financial condition.
- Our trust and wealth management business may be negatively impacted by changes in economic and market conditions and clients may seek legal remedies for investment performance.
- Increasing scrutiny and evolving expectations from customers, regulators, investors, and other stakeholders with respect to our environmental, social and governance practices may impose additional costs on us or expose us to new or additional risks.
- Climate change could have a material adverse impact on us and our customers.
- Credit and Interest Rate Risks
- If we fail to effectively manage credit risk, our business and financial condition will suffer.
- Our allowance for credit losses, or ACL, and fair value adjustments with respect to acquired loans, may be insufficient to absorb potential losses in our loan portfolio, which may adversely affect our business, financial condition and results of operations.
- Our loan portfolio is concentrated heavily in commercial and residential real estate loans, including exposure to construction loans, which involve risks specific to real estate values and the real estate markets in general.
- Real estate market volatility and future changes in disposition strategies could result in net proceeds that differ significantly from our fair value appraisals of loan collateral and OREO and could negatively impact our operating performance.
- We are subject to interest rate risk, and a change in interest rates could have a negative effect on our net income.
The other 39 risks
- Rapidly rising interest rates will impact the value of our investment securities and the cost of our funding sources, including deposits.
- Nonperforming assets take significant time to resolve, adversely affect our results of operations and financial condition and could result in further losses in the future.
- Operational Risks
- We are a community bank and our ability to maintain our reputation is critical to the success of our business and the failure to do so may materially adversely affect our performance.
- We operate in a highly competitive industry and market area and may face severe competitive disadvantages.
- We depend on our executive officers and other key employees, and our ability to attract additional key personnel, to continue the implementation of our long-term business strategy, and we could be harmed by the unexpected loss of their services.
- If we are unable to offer our key management personnel long-term incentive compensation, including options, restricted stock, and restricted stock units, as part of their total compensation package, we may have difficulty retaining such personnel, which would adversely affect our operations and financial performance.
- We depend on outside third parties for the processing and handling of our records and data.
- Our use of third-party vendors and our other ongoing third-party business relationships are subject to regulatory requirements and attention.
- We are at risk of increased losses from fraud.
- Privacy and Technology-Related Risks
- Failure to keep pace with technological change could adversely affect our business.
- Our information systems may experience an interruption or breach in security and cyber-attacks, all of which could have a material adverse effect on our business.
- The development and use of Artificial Intelligence (“AI”) presents risks and challenges that may adversely impact our business.
- Growth and Strategic Risks
- We may not be able to implement our growth strategy or manage costs effectively, resulting in lower earnings or profitability.
- Our strategic growth plans contemplate additional organic growth and potential growth through additional mergers and acquisitions, which exposes us to additional risks.
- Future acquisitions may be delayed, impeded, or prohibited due to regulatory issues.
- We may be exposed to difficulties in combining the operations of acquired or merged businesses, including First Merchants and Bancorp Financial, into our own operations, which may prevent us from achieving the expected benefits from our merger and acquisition activities.
- New lines of business, products, product enhancements or services may subject us to additional risks.
- Industry-Related Risks
- Our estimate of fair values for our investments may not be realizable if we were to sell these securities today.
- Monetary policies and regulations of the Federal Reserve could adversely affect our business, financial condition and results of operations.
- Our deposit insurance premiums could be substantially higher in the future, which could have a material adverse effect on our future earnings.
- Adverse developments affecting the financial services industry, such as recent bank failures or concerns involving liquidity, may have a material adverse effect on the Company’s operations.
- Legal, Accounting, Regulatory and Compliance Risks
- We face a risk of noncompliance with the Bank Secrecy Act and other anti-money laundering statutes and regulations and corresponding enforcement proceedings.
- We may be materially and adversely affected by the highly regulated environment in which we operate.
- We face risks related to the adoption of future legislation and potential changes in federal regulatory agency leadership, policies, and priorities.
- Our accounting estimates and risk management processes and controls rely on analytical and forecasting techniques and models and assumptions, which may not accurately predict future events.
- We are subject to fair lending laws, and failure to comply with these laws could lead to material penalties.
- We could be subject to changes in tax laws, regulations, and interpretations or challenges to our income tax provision.
- Given our expanded retail business we are subject to various state consumer protection laws and tax codes.
- We could become subject to claims and litigation pertaining to our fiduciary responsibility.
- We are defendants in a variety of litigation and other actions.
- From time to time we are, or may become, involved in suits, legal proceedings, information-gatherings, investigations and proceedings by governmental and self-regulatory agencies that may lead to adverse consequences.
- Capital and Liquidity Risks
- Our business needs and future growth may require us to raise additional capital, but that capital may not be available or may be dilutive.
- We could experience an unexpected inability to obtain needed liquidity.
- We may not be able to maintain a strong core deposit base or access other low-cost funding sources.
- Risks Related to an Investment in Our Common Stock
- Our future ability to pay dividends is subject to restrictions.
- The trading volumes in our common stock may not provide adequate liquidity for investors.
- The trading price of our common stock may be subject to continued significant fluctuations and volatility.
- Shares of our common stock are subject to dilution, which could cause our common stock price to decline.
- Certain banking laws and our governing documents may have an anti-takeover effect and may make it difficult and expensive to remove current management.
Legal proceedings
The Company and its subsidiaries have, from time to time, collection suits and other actions that arise in the ordinary course of business against its borrowers and are defendants in legal actions arising from normal business activities. Management, after consultation with legal counsel, believes that the ultimate liabilities, if any, resulting from these actions will not have a material adverse effect on the financial position of the Bank or on the consolidated financial position of the Company.
