Higher interest rates and wider spreads led to a decline in accumulated other comprehensive income associated with investment securities and related hedging activities, contributing approximately $1.63 to the decline in tangible book value per share during the third quarter of 2026. Debt securities totaled $5.2 billion as of September 30, 2026, a decrease of $551.3 million compared to June 30, 2026.

The unrealized loss on these securities is fully reflected in the value presented on the balance sheet. The portfolio also includes $553.0 million in securities classified as held-to-maturity with a fair value of $435.3 million. Continued strong loan origination volume supported an increase in loan balances of $428.8 million, or 13% annualized, during the third quarter of 2026.

Outside of these two funding sources, deposits grew 1.3% annualized in all other categories. Noninterest-bearing demand deposits have grown at an annualized rate of 10% year to date. The cost of deposits increased seven basis points to 1.60% from 1.53% in the prior quarter. At September 30, 2026, customer transaction account balances continued to represent 48% of total deposits.

Commercial deposits represented 53% of overall customer deposit funding with an average business customer balance of $120 thousand. Uninsured deposits represented 36% of overall deposit balances as of September 30, 2026.

Excluding such balances, the uninsured and uncollateralized deposits were 32% of total deposits. The Company has liquidity sources including cash and lines of credit with the Federal Reserve and Federal Home Loan Bank and other borrowings that represented 148% of uninsured deposits, and 165% of uninsured and uncollateralized deposits.

Nonperforming loans were $73.3 million, or 0.54% of total loans, at September 30, 2026, a decrease of $13.3 million, or 15%, from $86.5 million, or 0.66% of total loans, as of June 30, 2026 and an increase of $12.7 million, or 21%, from $60.6 million, or 0.55%, of total loans, at September 30, 2025. Accruing past due loans were $27.4 million, or 0.20% of total loans, at September 30, 2026, compared to $20.1 million, or 0.15% of total loans, at June 30, 2026, and $20.3 million, or 0.19% of total loans, at September 30, 2025. Net charge-offs were $5.4 million in the third quarter of 2026, compared to $3.2 million in both the second quarter of 2026 and the third quarter of 2025. Net charge-offs for the four most recent quarters averaged 0.10% of total loans. The ratio of ACL to total loans was 1.41% at September 30, 2026, an increase of three basis points compared to 1.38% at June 30, 2026, and was 1.34% at September 30, 2025. The increase in coverage is the result of an $8.4 million measurement period adjustment, identified and recorded in the third quarter of 2026, to the reserve for an acquired VBI loan. Portfolio diversification, in terms of asset mix, industry, and loan type, has been a critical element of the Company's lending strategy. Exposure across industries and collateral types is broadly distributed. Construction and land development and commercial real estate loans remain well below regulatory guidance as of September 30, 2026 at 45% and 250% of total bank-level risk-based capital 2 , respectively, compared to 40% and 230%, respectively, at June 30, 2026. On a consolidated basis and as of September 30, 2026, construction and land development and commercial real estate loans represented 41% and 227%, respectively, of total consolidated risk-based capital 2 . Capital and Liquidity The Company continues to operate with a fortress balance sheet, with a Tier 1 capital ratio at September 30, 2026 of 14.1% 2 compared to 14.3% at June 30, 2026, and 14.5% at September 30, 2025. The Total capital ratio was 15.5% 2 , the Common Equity Tier 1 capital ratio was 11.3% 2 , and the Tier 1 leverage ratio was 10.5% 2 at September 30, 2026. The Company is considered “well-capitalized” based on applicable U.S. regulatory capital ratio requirements. Tangible equity to tangible assets 3 was 8.63% at September 30, 2026, compared to 9.25% at June 30, 2026, and 9.76% at September 30, 2025, with the decline associated with the impact of higher rates on the securities portfolio recorded through accumulated other comprehensive income. If all held-to-maturity securities were also reflected at fair value, the tangible equity ratio would have been 8.22% at September 30, 2026. During 2026, the Company has taken opportunities to leverage its strong capital position by repurchasing over 1.2 million shares of its common stock under its share repurchase program. At September 30, 2026, in addition to $303.2 million in cash, the Company had $8.5 billion in available borrowing capacity, including $5.3 billion in available collateralized lines of credit, $2.8 billion of unpledged debt securities available as collateral for potential additional borrowings, and available unsecured lines of credit of $348.0 million. These liquidity sources as of September 30, 2026, represented 165% of uninsured and uncollateralized deposits. 1 Non-GAAP measure, see “Explanation of Certain Unaudited Non-GAAP Financial Measures" for more information and for a reconciliation to GAAP. 2 Estimated 3 The Company defines tangible assets as total assets less intangible assets and tangible equity as total shareholders' equity plus convertible preferred stock less intangible assets.

Prior to the fourth quarter of 2025, the Company's presentation of the efficiency ratio excluded amortization expense on intangible assets. Prior periods have been updated to align with the current presentation. 6 Calculated treating all convertible preferred shares as common. Each 1/1000th preferred share is convertible to one common share on the date a holder of preferred stock transfers such share of preferred stock to a non-affiliate of the holder. The Company believes a calculation presenting all convertible preferred shares as common provides useful supplemental information to the presentation of common share measures, as we anticipate they will be converted to common shares in the future. 7 In the fourth quarter of 2025, non-voting convertible preferred shares were issued in connection with the VBI acquisition. Those shares earn dividends pro-rata with common shares.

Explanation of Certain Unaudited Non-GAAP Financial Measures This presentation contains financial information determined by methods other than Generally Accepted Accounting Principles (“GAAP”). Management uses these non-GAAP financial measures in its analysis of the Company’s performance and believes these presentations provide useful supplemental information, and a clearer understanding of the Company’s performance. The Company believes the non-GAAP measures enhance investors’ understanding of the Company’s business and performance and if not provided would be requested by the investor community. 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 define or calculate these measures differently. The Company provides reconciliations between GAAP and these non-GAAP measures. These disclosures should not be considered an alternative to GAAP.
