Certain matters set forth herein constitute “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995, including forward-looking statements relating to the Company’s current business plans and expectations regarding future operating results. These forward-looking statements are subject to risks and uncertainties that could cause actual results, performance or achievements to differ materially from those projected. These risks and uncertainties, some of which are beyond our control, include, but are not limited to: business and economic conditions, particularly those affecting the financial services industry and our primary market areas; the continuing effects of inflation and monetary policies, and the impacts of those circumstances upon our current and prospective borrowers and depositors; our ability to mitigate and manage deposit liabilities in a manner that balances the need to meet current and expected withdrawals while investing a sufficient portion of our assets to promote strong earning capacity; our ability to successfully manage our credit risk and the sufficiency of our allowance for credit losses; factors that can impact the performance of our loan portfolio, including real estate values and liquidity in our primary market areas, the financial health of our commercial borrowers, the success of construction projects that we finance, including any loans acquired in acquisition transactions; our ability to effectively execute our strategic plan and manage our growth; interest rate fluctuations, which could have an adverse effect on our profitability; external economic and/or market factors, such as changes in monetary and fiscal policies and laws, including the interest rate policies of the Federal Reserve, inflation or deflation, changes in the demand for loans, and fluctuations in consumer spending, borrowing and savings habits, which may have an adverse impact on our financial condition; continued or increasing competition from other financial institutions, credit unions, and non-bank financial services companies, many of which are subject to less restrictive or less costly regulations than we are; challenges arising from unsuccessful attempts to expand into new geographic markets, products, or services; restraints on the ability of Open Bank to pay dividends to us, which could limit our liquidity; increased capital requirements imposed by banking regulators, which may require us to raise capital at a time when capital is not available on favorable terms or at all; a failure in the internal controls we have implemented to address the risks inherent to the business of banking; inaccuracies in our assumptions about future events, which could result in material differences between our financial projections and actual financial performance, particularly with respect to the effects of predictions of future economic conditions as those circumstances affect our estimates for the adequacy of our allowance for credit losses and the related provision expense; changes in our management personnel or our inability to retain motivate and hire qualified management personnel; disruptions, security breaches, or other adverse events, failures or interruptions in, or attacks on, our information technology systems; disruptions, security breaches, or other adverse events affecting the third-party vendors who perform several of our critical processing functions; an inability to keep pace with the rate of technological advances due to a lack of resources to invest in new technologies; risks related to potential acquisitions; political developments, uncertainties or instability, catastrophic events, acts of war or terrorism, or natural disasters, such as earthquakes, fires, drought, pandemic diseases (such as the coronavirus) or extreme weather events, any of which may affect services we use or affect our customers, employees or third parties with which we conduct business; incremental costs and obligations associated with operating as a public company; the impact of any claims or legal actions to which we may be subject, including any effect on our reputation; compliance with governmental and regulatory requirements, including the Dodd-Frank Act and others relating to banking, consumer protection, securities and tax matters, and our ability to maintain licenses required in connection with commercial mortgage origination, sale and servicing operations; changes in federal tax law or policy; and our ability the manage the foregoing and other factors set forth in the Company’s public reports. We describe these and other risks that could affect our results in Item 1A. “Risk Factors,” of our latest Annual Report on Form 10-K for the year ended December 31, 2022 and in our other subsequent filings with the Securities and Exchange Commission.
