8 Q2 2023 Financial Performance At-a-Glance 1For non-GAAP financial measures, see reconciliation to most directly comparable GAAP measures in “Appendix – Reconciliation of Non-GAAP Disclosures” Note: all tables presented dollars in thousands, except per share amounts • Net income available to common shareholders for the second quarter of 2023 was $52.3 million or $0.70 per share, up $19.6 million or $0.26 per share compared to the prior quarter. The results were driven by: • An increase in noninterest income, primarily due to losses incurred on the sale of available for sale (“AFS”) securities in the prior quarter, driven by the Company’s balance sheet repositioning transactions, and that were not repeating during the second quarter, • A decrease in the provision for credit losses, • A decrease in noninterest expense, reflecting the legal reserve recorded in the prior quarter associated with an ongoing regulatory matter as previously disclosed, partially offset by charges incurred in the second quarter related to our strategic cost saving initiatives, principally composed of severance charges related to headcount reductions and charges related to exiting leases, • A decrease in net interest income, primarily driven by higher deposit costs due to increases in market interest rates, as well as changes in the deposit mix as depositors migrated to higher costing interest bearing deposit accounts, partially offset by an increase in loan yields due primarily to variable rate loans repricing as short-term interest rates increased and the impact of loan growth. • Adjusted operating earnings available to common shareholders1 increased $8.2 million to $55.4 million at June 30, 2023 compared to the prior quarter, primarily driven by: • A decrease in the provision for credit losses, as noted above, • An increase in adjusted operating noninterest income1 , primarily due to an increase in loan-related interest rate swap fees and other operating income due to an increase in loan syndication revenue, partially offset by a decline in mortgage banking income, • A decrease in adjusted operating noninterest expense1 , primarily due to decreases in salaries and benefits expense, outside of severance charges related to headcount reductions in the quarter included in the strategic cost saving initiatives noted above, and other expenses primarily due to OREO-related gains recognized in the current quarter and reduced branch closing costs as compared to the prior quarter, partially offset by increases in professional services, marketing and advertising expense, and technology and data processing, • A decrease in net interest income, as noted above. 2Q2023 1Q2023 Net Income available to common shareholders $ 52,274 $ 32,686 Common EPS, diluted $ 0.70 $ 0.44 ROE 9.00% 5.97% ROTCE (non-GAAP)1 16.11% 10.71% ROA 1.10% 0.71% Efficiency ratio 59.94% 66.40% Efficiency ratio (FTE)1 58.72% 64.89% Net interest margin 3.37% 3.41% Net interest margin (FTE)1 3.45% 3.50% Earnings Metrics 2Q2023 1Q2023 Adjusted operating earnings available to common shareholders $ 55,381 $ 47,222 Adjusted operating common EPS, diluted $ 0.74 $ 0.63 Adjusted operating ROA 1.16% 1.00% Adjusted operating ROTCE 17.03% 15.22% Adjusted operating efficiency ratio (FTE) 55.30% 56.03% Adjusted operating earnings PTPP $ 74,553 $ 73,197 PTPP = Pre-tax Pre-provision Adjusted Operating Earnings Metrics - non-GAAP1 2Q2023 1Q2023 Net interest income $ 152,084 $ 153,443 - Provision for credit losses 6,069 11,850 + Noninterest income 24,197 9,628 - Noninterest expense 105,661 108,274 - Taxes 9,310 7,294 Net income (GAAP) $ 55,241 $ 35,653 - Dividends on preferred stock 2,967 2,967 Net income available to common shareholders (GAAP) $ 52,274 $ 32,686 + Strategic cost saving initiatives, net of tax 3,109 - + Legal reserve, net of tax - 3,950 - Gain (loss) on sale of securities, net of tax 2 (10,586) Adjusted operating earnings available to common shareholders (non-GAAP)1 $ 55,381 $ 47,222 Summarized Income Statement

9 Q2 2023 Allowance For Credit Loss (ACL) and Provision for Credit Losses Q2 Macroeconomic Forecast Moody’s June 2023 Baseline Forecast: • US GDP expected to average ~1.6% growth in 2023 and ~1.4% in 2024. • The national unemployment rate expected to average ~3.6% in 2023 and ~4.1% in 2024. • Virginia’s unemployment rate expected to average ~3.2% over the 2-year forecast period. Q2 ACL Considerations • The Virginia unemployment forecast used for 2Q23 considered a baseline forecast of ~3.2%, adjusted for the probability of worse-than baseline economic performance, resulting in an average weighted forecast of ~6.1%. • Qualitative factors were added for certain portfolios and other factors as deemed appropriate, consistent with prior quarter. • The reasonable and supportable forecast period is 2 years; followed by reversion to the historical loss average over 2 years; consistent with CECL adoption.

21 Reconciliation of Non-GAAP Disclosures The Company has provided supplemental performance measures on a tax-equivalent, tangible, operating, adjusted, or pre-tax pre-provision basis. These non-GAAP financial measures are a supplement to GAAP, which is used to prepare the Company’s financial statements, and should not be considered in isolation or as a substitute for comparable measures calculated in accordance with GAAP. In addition, the Company’s non-GAAP financial measures may not be comparable to non-GAAP financial measures of other companies. The Company uses the non-GAAP financial measures discussed herein in its analysis of the Company’s performance. The Company’s management believes that these non-GAAP financial measures provide additional understanding of ongoing operations, enhance comparability of results of operations with prior periods and show the effects of significant gains and charges in the periods presented without the impact of items or events that may obscure trends in the Company’s underlying performance.

22 Reconciliation of Non -GAAP Disclosures Adjusted operating measures exclude, as applicable, strategic cost saving initiatives (principally composed of severance charges related to headcount reductions and charges for exiting leases), a legal reserve associated with an ongoing regulatory matter previously disclosed, gains and losses on sale of securities, as well as the gain on sale of Dixon, Hubard, Feinour & Brown, Inc., (“DHFB”). The Company believes these non -GAAP adjusted measures provide investors with important information about the continuing economic results of the organization’s operations. Net interest income (FTE) and total adjusted revenue (FTE), which are used in computing net interest margin (FTE), efficiency ratio (FTE) and adjusted operating efficiency ratio (FTE), provide valuable additional insight into the net interest margin and the efficiency ratio by adjusting for differences in tax treatment of interest income sources. The entire FTE adjustment is attributable to interest income on earning assets, which is used in computing yield on earning assets. Interest expense and the related cost of interest - bearing liabilities and cost of funds ratios are not affected by the FTE components. The adjusted operating efficiency ratio (FTE) excludes, as applicable, the amortization of intangible assets, strategic cost saving initiatives, a legal reserve associated with an ongoing regulatory matter previously disclosed, gains and losses on sale of securities, as well as the gain on sale of DHFB. This measure is similar to the measure utilized by the Company when analyzing corporate performance and is also similar to the measure utilized for incentive compensation. The Company believes this adjusted measure provides investors with important information about the continuing economic results of the organization’s operations.

24 Reconciliation of Non-GAAP Disclosures Tangible assets and tangible common equity are used in the calculation of certain profitability, capital, and per share ratios. The Company believes tangible assets, tangible common equity and the related ratios are meaningful measures of capital adequacy because they provide a meaningful base for period-to-period and company-to-company comparisons, which the Company believes will assist investors in assessing the capital of the Company and its ability to absorb potential losses. The Company believes tangible common equity is an important indication of its ability to grow organically and through business combinations, as well as its ability to pay dividends and to engage in various capital management strategies. The Company also calculates adjusted tangible common equity to tangible assets ratios to exclude AOCI, which is principally comprised of unrealized losses on AFS securities, and to include the impact of unrealized losses on HTM securities. The Company believes that each of these ratios enables investors to assess the Company's capital levels and capital adequacy without the effects of changes in AOCI, some of which are uncertain and difficult to predict, or assuming that the Company realized all previously unrealized losses on HTM securities at the end of the period, as applicable.

The Company believes that ROTCE is a meaningful supplement to GAAP financial measures and is useful to investors because it measures the performance of a business consistently across time without regard to whether components of the business were acquired or developed internally. Adjusted operating measures exclude, as applicable, strategic cost saving initiatives (principally composed of severance charges related to headcount reductions and charges for exiting leases), a legal reserve associated with an ongoing regulatory matter previously disclosed, gains and losses on sale of securities, as well as the gain on sale of DHFB.
