Optimize Origin
•In January 2025, we announced our initiative to drive elite financial performance and enhance our award-winning culture.
•Built on three primary pillars:
◦Productivity, Delivery & Efficiency
◦Balance Sheet Optimization
◦Culture & Employee Engagement
•Established near term target of greater than a 1% ROAA run rate by 4Q25 and an ultimate target of top quartile ROAA.
•Near term target is being achieved in part by branch consolidation, headcount reduction, securities optimization, capital optimization, cash/liquidity management, mortgage restructuring, as well as other opportunistic efficiency optimizations throughout the organization.
•We believe the actions we have taken have or will drive earnings improvement of approximately $37.2 million, in total, annually on a pre-tax pre-provision basis.

Financial Highlights
•Net income was $8.6 million for the quarter ended September 30, 2025, reflecting a decrease of $6.0 million, or 41.1%, compared to the linked quarter. PTPP earnings(1) were $47.8 million for the quarter ended September 30, 2025, reflecting an increase of $26.3 million, or 122%, compared to the linked quarter.
•Net interest income was $83.7 million for the quarter ended September 30, 2025, reflecting an increase of $1.6 million, or 1.9%, compared to the linked quarter and is at its highest level in the previous ten quarters.

•Our fully tax equivalent net interest margin (“NIM-FTE”) expanded four basis points to 3.65% for the quarter ended September 30, 2025, compared to the quarter ended June 30, 2025, and is at its highest level in the previous ten quarters. The increase was primarily driven by a two-basis point increase in the yield earned on average interest-earning assets and a three-basis point decline in the rate paid on average interest-bearing liabilities.
•Total deposits were $8.33 billion at September 30, 2025, reflecting an increase of $208.8 million, or 2.6%, compared to June 30, 2025. Total noninterest-bearing deposits were $2.00 billion at September 30, 2025, reflecting an increase of $158.6 million, or 8.6%, compared to the linked quarter.
•During the quarter ended September 30, 2025, we repurchased 265,248 shares of our common stock at an average price of $35.85 per share. Year-to-date, we have repurchased 401,647 shares of our common stock at an average price of $34.59 per share.
•Book value per common share was $39.23 at September 30, 2025, reflecting an increase of $0.61, or 1.6%, compared to June 30, 2025, and $2.47, or 6.7%, compared to September 30, 2024. Tangible book value per common share(1) was $33.95 at September 30, 2025, reflecting increases of $0.62, or 1.9%, compared to June 30, 2025 and $2.58, or 8.2%, compared to September 30, 2024.
•As part of our Optimize Origin initiatives, we purchased additional shares of Argent Financial on July 1, 2025, which increased our ownership to more than 20%. This purchase required a change to how we account for this investment from the cost method to the equity method and resulted in a fair value adjustment gain and equity method investment income of $7.0 million and $1.2 million, respectively, recorded during the current quarter.

Results of Operations for the Quarter Ended September 30, 2025
Net Interest Income and Net Interest Margin
Net interest income for the quarter ended September 30, 2025, was $83.7 million, an increase of $1.6 million, or 1.9%, compared to the quarter ended June 30, 2025. A total increase of $2.2 million in net interest income was driven by an overall improvement in our funding mix, as growth in total deposits provided additional liquidity that was deployed into interest-earning balances due from banks and used to reduce borrowings. In addition, interest income earned on investment securities increased $1.2 million when compared to the linked quarter. These increases were partially offset by a $994,000 decrease in interest income earned on loans held for investment (“LHFI”).
The overall improvement in our funding mix was reflected in a $197.0 million increase in average interest-earning balances due from banks and an $81.2 million decrease in average balances of FHLB advances and other borrowings. The increase in average interest-earning balances due from banks contributed to a $2.1 million increase in interest income, while the decrease in average balances of FHLB advances and other borrowings contributed $883,000 of the total $943,000 decrease in interest expense during the quarter ended September 30, 2025. These increases in net interest income were partially offset by an $806,000 increase in interest expense on savings and interest-bearing transaction accounts, resulting from a $102.1 million increase in average savings and interest-bearing transaction accounts balances, when compared to the linked quarter.
The $1.2 million increase in interest income earned on investment securities was largely driven by the full-quarter benefit of the bond portfolio optimization strategy executed during the quarter ended June 30, 2025, in conjunction with our Optimize Origin initiative.
Interest income on LHFI decreased by $994,000, primarily due to lower average loan balances which drove a $2.8 million decline in LHFI interest income during the quarter ended September 30, 2025. The decrease was partially offset by $1.3 million in additional interest income as a result of one extra calendar day during the current quarter. The remaining change was mainly due to shifts in the loan mix, as overall LHFI yields remained stable at 6.33% for both quarters. The decrease in average LHFI principal balances was primarily due to decreases of $95.1 million, $73.4 million and $59.7 million in construction/land/land development loans, commercial and industrial loans and mortgage warehouse lines of credit (“MW LOC”), respectively, partially offset by increases of $42.5 million and $37.3 million in commercial real estate and residential real estate loans, respectively, during the quarter ended September 30, 2025.

The Federal Reserve Board sets various benchmark rates, including the federal funds rate, and thereby influences the general market rates of interest, including the loan and deposit rates offered by financial institutions. On September 17, 2025, the Federal Reserve reduced the federal funds target rate range by 25 basis points, to a range of 4.00% to 4.25%, decreasing the federal funds target range for the fourth time for a total of 125 basis points from its recent cycle high set in mid-2023.
Our NIM-FTE was 3.65% for the quarter ended September 30, 2025, representing four- and 47-basis-point increases compared to the linked quarter and the quarter ended September 30, 2024, respectively. The yield earned on interest-earning assets for the quarter ended September 30, 2025, was 5.89%, an increase of two basis points compared to the linked quarter and a decrease of 20 basis points compared to the quarter ended September 30, 2024. The average rate paid on total interest-bearing liabilities for the quarter ended September 30, 2025, was 3.22%, representing a reduction of three- and 82-basis points compared to the linked quarter and the quarter ended September 30, 2024, respectively.

| At and For the Three Months Ended |  | Change |  | % Change |
(Dollars in thousands, unaudited) | September 30, 2025 |  | June 30, 2025 |  | September 30, 2024 |  | Linked Quarter |  | Linked Quarter |
Past due LHFI(1) | $ | 72,512 |  |  | $ | 67,626 |  |  | $ | 38,838 |  |  | $ | 4,886 |  |  | 7.2 | % |

___________________________
N/A = Not applicable.
N/M = Not meaningful
(1)Past due LHFI are defined as loans 30 days or more past due and includes past due nonperforming loans.
(2)Please see the Loan Data schedule at the back of this document for additional information.
(3)The ALCL to total LHFI, adjusted, is calculated by excluding the ALCL for MW LOC loans from the total LHFI ALCL in the numerator and excluding the MW LOC loans from the LHFI in the denominator. Due to their low-risk profile, MW LOC loans require a disproportionately low allocation of the ALCL.
Our results included a credit loss provision expense of $36.8 million during the quarter ended September 30, 2025, which includes a $35.2 million provision for loan credit losses, compared to provision for loan credit losses of $2.7 million for the linked quarter. The total credit loss provision increase was primarily related to the suspected borrower fraud impacting the Tricolor Holdings, LLC loan relationship which was previously disclosed in our Current Report on Form 8-K filed on September 10, 2025, and drove a $29.5 million increase in the total provision, consisting of a $28.1 million provision for loan credit losses and a $1.5 million provision for off-balance sheet commitments. We are pursuing all possible opportunities for recovery. Also contributing to the increase in provision for loan credit losses was a $1.7 million increase in the provision for relationships impacted by the questioned banker activity first disclosed during the quarter ended June 30, 2024. Our provision for loan credit losses, exclusive of these events, would have been $5.5 million for the quarter ended September 30, 2025, representing a $2.8 million increase compared to the linked quarter primarily due to increases in construction/land/land development and commercial and industrial credit loan loss provisions.
Net charge-offs increased $29.1 million for the quarter ended September 30, 2025, when compared to the quarter ended June 30, 2025, primarily due to net charge-offs of $28.4 million in the current quarter related to the relationship with Tricolor Holdings, LLC, discussed above.

Noninterest Income
Noninterest income for the quarter ended September 30, 2025, was $26.1 million, an increase of $24.8 million from the linked quarter, primarily driven by a $14.4 million loss on sales of securities, net in the linked quarter, and $7.0 million, $2.5 million and $2.1 million increases in changes in fair value of equity investments, equity method investment income (loss) and other income, respectively, in the current quarter. These increases were partially offset by a decrease of $643,000 in mortgage banking revenue.
The $14.4 million loss on sales of securities, net, during the linked quarter was due to the execution of the bond portfolio optimization strategy discussed in detail in the linked quarter earnings release.
The $7.0 million increase in the fair value of equity method investments was driven by the additional investment in Argent Financial which increased our ownership percentage above the threshold required to implement the equity method of accounting. The equity method of accounting requires the asset be recorded at fair value immediately prior to the purchase, and therefore required an upward adjustment to its basis.
The components of equity method investment income are as follows:

| At and For the Three Months Ended |  | Change |  | % Change
(Dollars in thousands, unaudited) | September 30, 2025 |  | June 30, 2025 |  | September 30, 2024 |  | Linked Quarter |  | Linked Quarter
Argent investment income | $ | 1,227 |  |  | $ | — |  |  | $ | — |  |  | $ | 1,227 |  |  | N/M
Limited partnership investment (loss) income | (677) |  |  | (1,909) |  |  | 375 |  |  | 1,232 |  |  | 64.5 | %
Total equity method investment income | $ | 550 |  |  | $ | (1,909) |  |  | $ | 375 |  |  |  |  |

___________________________
N/M = Not meaningful
The $2.5 million increase in equity method investment income (loss) was primarily driven by a $1.7 million downward adjustment in one limited partnership investment during the linked quarter. Also contributing to the increase was Argent equity method investment income totaling $1.2 million.
The $2.1 million increase in other income was due to insurance recoveries in connection with the previously disclosed questioned banker activity.
The $643,000 decrease in mortgage banking revenue was primarily due to a decrease in origination and sales volume in the current quarter.
Noninterest Expense
Noninterest expense for the quarter ended September 30, 2025, was $62.0 million, an increase of $45,000, or 0.1% from the linked quarter. There were no material changes in noninterest expense income statement line items compared to the linked quarter.
Financial Condition
Loans
•Total LHFI at September 30, 2025, were $7.54 billion, a decrease of $147.3 million, or 1.9%, from $7.68 billion at June 30, 2025, and a decrease of $419.7 million, or 5.3%, compared to September 30, 2024.
•The primary drivers of the decrease during the quarter ended September 30, 2025, compared to the linked quarter, were decreases in MW LOC and commercial and industrial loans of $101.8 million and $91.4 million, respectively. These decreases were partially offset by an increase of $64.2 million in non-owner occupied commercial real estate.
4

Securities
•Total securities at September 30, 2025 were $1.12 billion, a decrease of $22.5 million, or 2.0%, from $1.14 billion at June 30, 2025, and a decrease of $57.0 million, or 4.8%, compared to September 30, 2024.
•The decrease in securities was primarily due to scheduled principal paydowns, calls and maturities of short-term investments securities during the current quarter.
•Accumulated other comprehensive loss, net of taxes, primarily associated with unrealized losses within the available for sale portfolio, was $61.2 million at September 30, 2025, a decrease of $12.4 million, or 16.9% , from the linked quarter.
•The weighted average effective duration for the total securities portfolio was 4.31 years as of September 30, 2025, compared to 4.52 years as of June 30, 2025.
Equity Method Investments
•Equity method securities at September 30, 2025, were $65.6 million, an increase of $49.8 million, or 313.8%, compared to June 30, 2025, and an increase of $45.7 million, or 228.8% from September 30, 2024. The primary driver of the increase was a change in presentation as described immediately below.
•As a result of our Optimize Origin initiative and during the quarter ended September 30, 2025, we made an additional investment in Argent Financial which increased our ownership percentage above the threshold required to implement the equity method of accounting. The implementation of the equity method of accounting resulted in a change in presentation to the underlying asset from nonmarketable equity securities held in other financial institutions to equity method investments and required a remeasurement of the fair value of the asset before applying equity method accounting.
•The remeasurement of the asset resulted in a $7.0 million fair value adjustment gain and, subsequent to the implementation of equity method accounting, we recorded equity method investment income of $1.2 million during the current quarter. As of September 30, 2025, the carrying value of our total investment in Argent Financial was $49.8 million.
•We estimate that our investment in Argent Financial should result in a pre-tax annualized benefit of approximately $6.0 million beginning in the fourth quarter of 2025.
Deposits
•Total deposits at September 30, 2025, were $8.33 billion, an increase of $208.8 million, or 2.6%, compared to June 30, 2025, and a decrease of $154.7 million, or 1.8%, from September 30, 2024.
•The increase in total deposits at September 30, 2025, compared to the linked quarter was primarily due to increases of $158.6 million and $99.3 million in noninterest-bearing demand deposits and money market deposits, respectively. The increase was partially offset by a decrease of $35.6 million in interest-bearing demand deposits.
•At September 30, 2025, and June 30, 2025, noninterest-bearing deposits as a percentage of total deposits were 24.0% and 22.7%, respectively. At September 30, 2024, noninterest-bearing deposits as a percentage of total deposits were 22.3%.
Borrowings
•FHLB advances and other borrowings at September 30, 2025, were $12.8 million, a decrease of $115.1 million from $127.8 million at June 30, 2025, and a decrease of $17.7 million compared to September 30, 2024. The decrease was primarily due to growth in total deposits in the current quarter compared to the linked quarter.
•Average FHLB advances were $22.9 million for the quarter ended September 30, 2025, a decrease of $81.6 million from $104.5 million for the quarter ended June 30, 2025 and a decrease of $10.4 million from September 30, 2024.

____________________________
(1)Nonperforming assets consist of nonperforming/nonaccrual loans and property acquired through foreclosures or repossession, as well as bank-owned property not in use and listed for sale, if any.
(2)Includes multi-family real estate.
(3)Past due LHFI are defined as loans 30 days or more past due and includes past due nonperforming loans.
(4)The ALCL to total LHFI, adjusted is calculated by excluding the ALCL for MW LOC loans from the total LHFI ALCL in the numerator and excluding the MW LOC loans from the LHFI in the denominator. Due to their low-risk profile, MW LOC loans require a disproportionately low allocation of the ALCL.
