Deposits (1) Not presented in accordance with GAAP. See “Non-GAAP Measures” for reconciliation of this measure to its most comparable GAAP measure. 1Q23 Highlights • Total deposits increased $95.7MM (4.5%) and retail deposits increased $25.7MM (1.3%) • Uninsured deposits decreased to $1.02B (47.6% of total deposits) compared to $1.06B (51.9% of total deposits) at 12/31/22

See “Non-GAAP measure” for reconciliations of these measures to their most comparable GAAP measures. (2) Full-Time Equivalents 1Q23 Highlights • While net income increased, PTPP decreased due to a reversal of credit loss of $2.8MM compared to a provision for loan losses of $1.1MM in 4Q22, a $1.9MM decrease net interest income, and a $639K increase in noninterest expense, partially offset by a $632K increase in noninterest income

Net Interest Margin (1) Annualized 1Q23 Highlights • Net interest income decreased $1.8MM to $22.4MM from $24.3MM for 4Q22. • Net interest margin decreased to 3.78% from 4.15% for 4Q22 mainly due to an increase in cost of average interest-bearing liabilities, partially offset by an increase in yield on average interest- earning assets.

Capital (1) Not presented in accordance with GAAP. See “Non-GAAP Measures” for reconciliation of this measure to its most comparable GAAP measure.

Non-GAAP Measures Adjusted ACL to HFI Loans Ratio Adjusted ACL to HFI loans ratio is a non-GAAP measure that we use to enhance comparability to prior periods and provide supplemental information regarding the Company’s credit trends. We calculate adjusted ACL to HFI loan ratio as ACL divided by loans held-for-investment excluding SBA PPP loans; however, this non-GAAP measure had become less significant as most of SBA PPP loan balance were forgiven or paid off during 2022. Core Deposits Core Deposits are a non-GAAP measure that we use to measure the portion of our total deposits that are thought to be more stable, lower cost and reprice less frequently on average in a rising rate environment. We calculate core deposits as total deposits less time deposits greater than $250,000 and brokered deposits. Management tracks its core deposits because management believes it is a useful measure to help assess the Company’s deposit base and, among other things, potential volatility therein. PTPP Income, and Adjusted ROAA, ROAE and Diluted EPS for PTPP PTPP income, and adjusted ROAA, ROAE and Diluted EPS are non-GAAP measures that we use to measure the Company’s performance and believe these presentations provide useful supplemental information, and a clearer understanding of the Company’s performance. We calculated PTPP income as net income excluding income tax provision and provision for loan losses. Management believes the non-GAAP measures enhance investors’ understanding of the Company’s business and performance. These measures are also useful in understanding performance trends and facilitate comparisons with the performance of other financial institutions. The limitations associated with operating measures are the risk that persons might disagree as to the appropriateness of items comprising these measures and that different companies might calculate these measures differently ROATCE, TCE Per Share and TCE to Total Assets ROATCE, TCE per share and TCE to total assets measures that we use to measure the Company’s performance. We calculated TCE as total shareholders’ equity excluding preferred stock. Management believes the non-GAAP measures provide useful supplemental information, and a clearer understanding of the Company’s performance.
