(iii) the credit risks of lending activities, which may be affected by deterioration in real estate markets and the financial condition of borrowers, and the operational risk of lending activities, including the effectiveness of our underwriting practices and the risk of fraud, any of which may lead to increased loan delinquencies, losses, and non-performing assets, and may result in our allowance for credit losses not being adequate; (iv) fluctuations in the demand for loans, and fluctuations in commercial and residential real estate values in our market area; (v) the quality and composition of our securities portfolio; (vi) our ability to develop and maintain a strong core deposit base, including among our venture banking and private banking clients, or other low cost funding sources necessary to fund our activities particularly in a rising or high interest rate environment;

(xiv) results of examinations by regulatory authorities of the Company and the possibility that any such regulatory authority may, among other things, limit our business activities, restrict our ability to invest in certain assets, refrain from issuing an approval or non- objection to certain capital or other actions, increase our allowance for credit losses, result in write-downs of asset values, restrict our ability or that of our bank subsidiary to pay dividends, or impose fines, penalties or sanctions; (xv) legislative or regulatory changes that adversely affect our business, including changes in tax laws and policies, accounting policies and practices, privacy laws, and regulatory capital or other rules; (xvi) the risk that our enterprise risk management framework may not be effective in mitigating risk and reducing the potential for losses; (xvii) errors in estimates of the fair values of certain of our assets and liabilities, as well as the value of collateral supporting our loans, which may result in significant changes in valuation or recoveries; (xviii) cybersecurity threats and failures or security breaches with respect to the network, applications, vendors and computer systems on which we depend; (xix) our ability to attract and retain key members of our senior management team; (xx) the effects of climate change, severe weather events, natural disasters such as earthquakes and wildfires, pandemics, epidemics and other public health crises, geopolitical conflicts and military activity (including the ongoing Iran war) or acts of terrorism, and other external events on our business; (xxi) the impact of bank failures or other adverse developments at other banks on general depositor and investor sentiment regarding the stability and liquidity of banks; (xxii) the possibility that our recorded goodwill could become impaired, which may have an adverse impact on our earnings and capital;

Non-GAAP Measures

Non-GAAP Financial Information Third Quarter 2026 Earnings | 33 Tangible assets, tangible common equity, tangible common equity ratio, tangible book value per common share, return on average tangible common equity, pre-tax pre-provision (“PTPP”) income, adjusted noninterest expense, efficiency ratio, adjusted efficiency ratio, and adjusted ACL ratio constitute supplemental financial information determined by methods other than in accordance with GAAP. These non-GAAP measures are used by management in its analysis of the Company's performance. Tangible assets is calculated by subtracting goodwill and other intangible assets from total assets. Tangible common equity is calculated by subtracting preferred stock and goodwill and other intangible assets, as applicable, from stockholders’ equity. Return on average tangible common equity is calculated by dividing net earnings available to common stockholders, after adjustment for amortization of intangible assets and goodwill impairment, by average tangible common equity. Adjusted return on average tangible common equity is calculated by dividing adjusted net earnings available to common stockholders, after adjustment for amortization of intangible assets and goodwill impairment, by average tangible common equity. Banking regulators also exclude goodwill and other intangible assets from stockholders' equity when assessing the capital adequacy of a financial institution. PTPP income is calculated by adding net interest income and noninterest income (total revenue) and subtracting noninterest expense. Adjusted noninterest expense is calculated by subtracting customer related expenses from noninterest expense. Efficiency ratio is calculated by dividing noninterest expense (less intangible asset amortization and acquisition, integration and reorganization costs) by total revenue (the sum of net interest income and noninterest income, less gain (loss) on securities AFS). Adjusted efficiency ratio is calculated by dividing adjusted noninterest expense (less intangible asset amortization and acquisition, integration and reorganization costs, customer related expenses and any unusual one-time items) by adjusted total revenue (the sum of net interest income and noninterest income, less gain (loss) on securities AFS and customer related expense). Core deposits is calculated as total deposits less brokered CDs and brokered non-maturity deposits. Core loan portfolio is calculated as total loans held for investment less premium finance loans, student loans, and Civic loans. Adjusted ACL ratio is calculated by dividing adjusted ACL for lower loss loan categories by adjusted loans and leases held for investment. Management believes the presentation of these financial measures adjusting the impact of these items provides useful supplemental information that is essential to a proper understanding of the financial results and operating performance of the Company. This disclosure should not be viewed as a substitute for results determined in accordance with GAAP, nor is it necessarily comparable to non-GAAP performance measures that may be presented by other companies. The following tables on pages 34-41 provide reconciliations of the non-GAAP measures to financial measures defined by GAAP.
