For Immediate Release

ORIGIN BANCORP, INC. REPORTS EARNINGS FOR FOURTH QUARTER AND FULL YEAR 2024

RUSTON, Louisiana (January 22, 2025) - Origin Bancorp, Inc. (NYSE: OBK) (“Origin,” “we,” “our” or the “Company”), the holding company for Origin Bank (the “Bank”), today announced net income of $14.3 million, or $0.46 diluted earnings per share (“EPS”) for the quarter ended December 31, 2024, compared to net income of $18.6 million, or $0.60 diluted earnings per share, for the quarter ended September 30, 2024. Pre-tax, pre-provision (“PTPP”)(1) earnings was $12.6 million for the quarter ended December 31, 2024, compared to $28.3 million for the linked quarter.

Net income for the year ended December 31, 2024, was $76.5 million, or $2.45 diluted earnings per share, representing a decrease of $0.26, or 9.6%, from diluted earnings per share of $2.71 for the year ended December 31, 2023. Pre-tax, pre-provision (“PTPP”)(1) earnings for the year ended December 31, 2024, was $104.7 million, representing a decrease of $18.0 million, or 14.6%, from the year ended December 31, 2023.

“I am excited about where we are going as a company as we enter 2025 with an organizational commitment to what Optimize Origin means to all of our stakeholders. This initiative is the continual enhancement of our award-winning culture and the drive for elite financial performance.” said Drake Mills, chairman, president and CEO of Origin Bancorp, Inc. “Our team has worked hard over the past year creating and implementing a strategy that is the basis for the next evolution of our company.”

(1) PTPP earnings is a non-GAAP financial measure, please see the last few pages of this document for a reconciliation of this alternative financial measure to its most directly comparable GAAP measure.

Optimize Origin

•Our newly announced 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 will be achieved in part by branch consolidation, headcount reduction, securities optimization, capital optimization, and cash/liquidity management

•We believe the actions we have taken will drive earnings improvement of approximately $21 million annually on a pre-tax pre-provision basis.

Financial Highlights

•Our fully tax equivalent net interest margin (“NIM-FTE”) expanded 15 basis points for the quarter ended December 31, 2024, compared to the quarter ended September 30, 2024. This expansion was driven primarily by a 40 basis point reduction in rates paid on interest-bearing liabilities, offset by an 18 basis point decline in our yield on interest-earning assets.

•Net interest income was $78.3 million for the quarter ended December 31, 2024, reflecting an increase of $3.5 million, or 4.7%, compared to the linked quarter and is at its highest level in two years.

•Provision for credit loss benefit was $5.4 million for the quarter ended December 31, 2024, compared to a provision for credit loss expense of $4.6 million in the linked quarter, representing a $10.0 million change from the linked quarter.

•Our bond portfolio optimization strategy, aimed at enhancing long-term yields and improving overall portfolio performance, positively impacted our NIM-FTE by three basis points for the quarter ended December 31, 2024, and is estimated to provide a total positive impact to NIM-FTE of seven basis points in the twelve months following the date of sale. We sold available-for-sale investment securities with a book value of $188.2 million and realized a loss of $14.6 million, which negatively impacted our diluted EPS by $0.37 for the quarter ended December 31, 2024.

Results of Operations for the Three Months Ended December 31, 2024

Net Interest Income and Net Interest Margin

Net interest income for the quarter ended December 31, 2024, was $78.3 million, an increase of $3.5 million, or 4.7%, compared to the quarter ended September 30, 2024. The increase was primarily driven by a $7.5 million decrease in interest expense paid on interest-bearing deposits and a $1.6 million increase in interest income earned on average interest-earning balances due from banks, partially offset by a decrease of $6.1 million in interest income earned on loans held for investment (“LHFI”).

The decrease in average rates and average balances of interest-bearing deposits during the quarter ended December 31, 2024, reduced interest expense by $6.2 million and $1.3 million, respectively, when compared to the quarter ended September 30, 2024. The decrease in average balances of interest-bearing deposits was primarily driven by a $256.3 million decrease in average time deposit balances, partially offset by a $190.5 million increase in average money market deposit balances. The average rate on interest-bearing deposits was 3.61% for the quarter ended December 31, 2024, a decrease of 40 basis points, from 4.01% for the quarter ended September 30, 2024.

The $1.6 million increase in interest income earned on average interest-earning balances due from banks was primarily driven by a $165.6 million increase in average interest-earning balances due from banks which led to a $2.3 million increase in interest income, partially offset by a reduction in average yield.

The decrease in average rates and average principal balance of LHFI during the quarter ended December 31, 2024, resulted in decreases of $3.4 million and $2.7 million, respectively, to interest income when compared to the quarter ended September 30, 2024. The average rate on LHFI was 6.47% for the quarter ended December 31, 2024, a decrease of 20 basis points, compared to 6.67% for the quarter ended September 30, 2024. The decrease in average LHFI principal balance was primarily driven by decreases of $83.2 million, $43.7 million and $25.0 million in average construction/land/land development, commercial and industrial and mortgage warehouse lines of credit (“MW LOC”) loan balances.

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 18, 2024, the Federal Reserve reduced the federal funds target rate range by 50 basis points, to a range of 4.75% to 5.00%, marking the first rate reduction since early 2020. Subsequently, it implemented two additional reductions, with the current federal funds target range set to 4.25% to 4.50% on December 18, 2024. During the second half of 2024, the federal funds target range decreased 100 basis points from its recent cycle high.

Our NIM-FTE was 3.33% for the quarter ended December 31, 2024, representing a 15- and a 14-basis-point increase compared to the linked quarter and the prior year same quarter, respectively. The yield earned on interest-earning assets for the quarter ended December 31, 2024, was 5.91%, a decrease of 18 basis points compared to the linked quarter and an increase of five basis points compared to the quarter ended December 31, 2023. The average rate paid on total interest-bearing liabilities for the quarter ended December 31, 2024, was 3.64%, representing a 40- and 11-basis point decrease compared to the quarters ended September 30, 2024, and December 31, 2023, respectively. The bond portfolio optimization strategy positively impacted our NIM-FTE by three basis points for the quarter ended December 31, 2024.

During the quarter ended December 31, 2024, we executed a bond portfolio optimization strategy aimed at enhancing long-term yields and improving overall portfolio performance. This strategy involved selling lower-yielding available-for-sale investment securities prior to their maturity and using the proceeds to purchase higher-yielding available-for-sale investment securities. As a result, we replaced securities with a total book value of $188.2 million and a weighted average yield of 1.51% with new securities totaling $173.7 million with a weighted average yield of 5.22%, realizing a loss of $14.6 million. The weighted average duration of the securities portfolio increased to 4.46 years as of December 31, 2024, compared to 4.21 years as of September 30, 2024. While the associated loss, net of the increase in interest income, resulted in a $0.35 negative impact to diluted EPS during the quarter ended December 31, 2024, we believe the trade-off in yield represents an attractive opportunity with an estimated increase in annual net interest income of $5.6 million, an earn-back period of 2.4 years and a twelve month total positive impact to NIM-FTE of seven basis points.

Credit Quality

The table below includes key credit quality information:

___________________________

(1)Please see the Loan Data schedule at the back of this document for additional information.

(2)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.

As discussed previously in our Origin Bancorp, Inc. Earnings Releases, our credit metrics were negatively impacted by certain questioned activity involving a former banker in our East Texas market. Our investigation of this activity remains ongoing. During the current quarter, classified and nonperforming LHFI related to the questioned banker activity decreased $5.8 million and $3.8 million, respectively, from September 30, 2024. This decline was primarily driven by one $2.0 million classified loan paying off and, as a result of our on-going investigation and litigation, the decision to remove $3.3 million in classified/nonperforming LHFI balances due to results from a third-party forensic analysis. We released $3.2 million in provision for loan credit losses related to the questioned banker activity and recorded a net contingency reserve increase of $3.1 million during the quarter ended December 31, 2024. There was no material change in the level of past due LHFI principal balances between the current quarter and the linked quarter as a result of the questioned activity. While the forensic analysis is largely completed, we continue to work with the outside forensic accounting firm to confirm the bank’s identification and reconciliation of the activity. At this time, we continue to believe that any ultimate loss arising from the situation will not be material to our financial position. The Company has notified its insurance providers of anticipated claims resulting from this activity, but there is no consideration in the Company’s financial results of any potential insurance recoveries.

Our results included a credit loss provision benefit of $5.4 million during the quarter ended December 31, 2024, which was primarily driven by a $5.5 million release of loan credit loss provision, $3.2 million of which was related to the questioned banker activity discussed in the previous paragraph. Also contributing to the release of the loan credit loss provision during the quarter ended December 31, 2024, compared to September 30, 2024, was a decrease of $237.0 million in total LHFI excluding MW LOC and an increase in loan recoveries of $879,000. Net charge-offs decreased $10.1 million for the quarter ended December 31, 2024, when compared to the quarter ended September 30, 2024, primarily due to total charge-offs of $2.0 million in the current quarter compared to total charge-offs of $11.2 million in the linked quarter consisting primarily of three commercial and industrial loan relationships with charge-offs totaling $10.4 million. Nonperforming LHFI increased $10.7 million for the current quarter compared to the linked quarter, reflecting an increase in the percentage of nonperforming LHFI to LHFI to 0.99% compared to 0.81% for the linked quarter. The increase in nonperforming loans was primarily driven by four loan relationships totaling $14.4 million at December 31, 2024, with single-family residential real estate loans totaling $8.1 million of the increase. Classified loans increased $11.3 million to $118.8 million at December 31, 2024.

Noninterest Income

Noninterest income for the quarter ended December 31, 2024, was a negative $330,000, a decrease of $16.3 million from the linked quarter, primarily driven by decreases of $14.8 million and $1.5 million in the change in gain (loss) on sales of securities, net and insurance commission and fee income, respectively.

The decrease in gain (loss) on sales of securities, net, during the current quarter when compared to the linked quarter was due to the execution of the bond portfolio optimization strategy discussed above. The loss on the sale of securities negatively impacted our diluted EPS by $0.37 for the quarter ended December 31, 2024.

The decrease in insurance commission and fee income was primarily due to the seasonal nature of insurance income.

Noninterest Expense

Noninterest expense for the quarter ended December 31, 2024, was $65.4 million, an increase of $2.9 million, or 4.6% from the linked quarter. The increase was primarily driven by increases of $3.4 million and $1.6 million in other noninterest expense and occupancy and equipment expense, net, respectively, that was partially offset by a decrease of $2.1 million in salaries and employee benefit expense.

The increase in other noninterest expense was primarily due to $3.1 million in contingency expense related to certain questioned activity involving a former banker in our East Texas market, as described in the Credit Quality section above. We had previously recorded a $3.2 million provision for loan credit losses and a $1.2 million contingency reserve during the quarter ended June 30, 2024. As a result of our on-going investigation of this matter, and to more accurately reflect the nature of the expense, we released the provision expense. This resulted in a reduction to our loan credit loss allowance through provision expense and an increase of our contingency reserve in other noninterest expense.

The $1.6 million increase in occupancy and equipment, net was primarily due to an increase in rent associated with the accounting for our strategic Optimize Origin initiative which includes consolidation of six banking centers, four in the Dallas-Fort Worth market, with one each in the Louisiana and Mississippi markets. We expect to close these six banking centers at the end of February 2025, which is expected to reduce our occupancy expense by approximately $3.6 million annually. These branch closures combined with the two branch closures that occurred mid-year 2024 are expected to reduce our annual occupancy expense by $4.6 million in total.

The decrease in salaries and employee benefit expense was primarily due to an Employee Retention Credit (“ERC”) of $1.7 million that was recorded in the current quarter and related to the operations of BTH Bank, N.A., which we acquired in 2022. The ERC is a refundable tax credit for certain eligible businesses that had employees affected during the COVID-19 pandemic.

Financial Condition

Loans

•Total LHFI at December 31, 2024, were $7.57 billion, a decrease of $383.1 million, or 4.8%, from $7.96 billion at September 30, 2024, and a decrease of $87.2 million, or 1.1%, compared to December 31, 2023.

•During the quarter ended December 31, 2024, compared to the linked quarter, we experienced declines in significantly all loan categories, but primarily reflected in MW LOC and construction/land/land development loans of $146.1 million and $127.5 million, respectively.

Securities

•During the quarter, we made a strategic decision to optimize our bond portfolio by selling available-for-sale investment securities with a book value of $188.2 million and realized a loss of $14.6 million.

•Accumulated other comprehensive loss, net of taxes, primarily associated with unrealized losses within the available for sale portfolio, was $106.0 million at December 31, 2024, an increase of $11.8 million, or 12.5% , from the linked quarter.

For a discussion of these and other risks that may cause actual results to differ from expectations, please refer to the sections titled “Cautionary Note Regarding Forward-Looking Statements” and “Risk Factors” in Origin’s most recent Annual Report on Form 10-K filed with the Securities and Exchange Commission and any updates to those sections set forth in Origin’s subsequent Quarterly Reports on Form 10-Q and Current Reports on Form 8-K. If one or more events related to these or other risks or uncertainties materialize, or if Origin’s underlying assumptions prove to be incorrect, actual results may differ materially from what Origin anticipates. Accordingly, you should not place undue reliance on any forward-looking statements. Any forward-looking statement speaks only as of the date on which it is made, and Origin does not undertake any obligation to publicly update or review any forward-looking statement, whether as a result of new information, future developments or otherwise.

New risks and uncertainties arise from time to time, and it is not possible for Origin to predict those events or how they may affect Origin. In addition, Origin cannot assess the impact of each factor on Origin’s business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements. All forward-looking statements, expressed or implied, included in this communication are expressly qualified in their entirety by this cautionary statement. This cautionary statement should also be considered in connection with any subsequent written or oral forward-looking statements that Origin or persons acting on Origin’s behalf may issue. Annualized, pro forma, adjusted, projected, and estimated numbers are used for illustrative purposes only, are not forecasts, and may not reflect actual results.

This press release contains projected financial information with respect to Origin, including with respect to certain goals and strategic initiatives of Origin and the anticipated benefits thereof. This projected financial information constitutes forward-looking information and is for illustrative purposes only and should not be relied upon as necessarily being indicative of future results. The assumptions and estimates underlying such projected financial information are inherently uncertain and are subject to significant business, economic (including interest rate), competitive, and other risks and uncertainties.

____________________________

(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.

(2)Includes multi-family real estate.

(3)Past due LHFI are defined as loans 30 days or more past due.

(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.

Forward-looking statements include information regarding Origin Bancorp, Inc’s (“Origin”, “we”, “our” or the “Company”) future financial performance, business and growth strategies, projected plans and objectives, and any expected purchases of its outstanding common stock, and related transactions and other projections based on macroeconomic and industry trends, including changes to interest rates by the Federal Reserve and the resulting impact on Origin’s results of operations, estimated forbearance amounts and expectations regarding the Company’s liquidity, including in connection with advances obtained from the FHLB, which are all subject to change and may be inherently unreliable due to the multiple factors that impact broader economic and industry trends, and any such changes may be material.

Further, certain factors that could affect Origin’s future results and cause actual results to differ materially from those expressed in the forward- looking statements include, but are not limited to: (1) the impact of current and future economic conditions generally and in the financial services industry, nationally and within Origin’s primary market areas, as well as the financial stress on borrowers and changes to customer and client behavior as a result of the foregoing; (2) changes in benchmark interest rates and the resulting impacts on net interest income; (3) deterioration of Origin’s asset quality; (4) factors that can impact the performance of Origin’s loan portfolio, including real estate values and liquidity in Origin’s primary market areas; (5) the financial health of Origin’s commercial borrowers and the success of construction projects that Origin finances; (6) changes in the value of collateral securing Origin’s loans; (7) the impact of generative artificial intelligence; (8) Origin’s ability to anticipate interest rate changes and manage interest rate risk; (9) the impact of heightened regulatory requirements, reduced debit interchange and overdraft income and the possibility of facing related adverse business consequences if our total assets grow in excess of $10 billion as of December 31 of any calendar year; (10) the effectiveness of Origin’s risk management framework and quantitative models; (11) Origin’s inability to receive dividends from Origin Bank and to service debt, pay dividends to Origin’s common stockholders, repurchase Origin’s shares of common stock and satisfy obligations as they become due; (12) the impact of labor pressures; (13) changes in Origin’s operation or expansion strategy or Origin’s ability to prudently manage its growth and execute its strategy; (14) changes in management personnel; (15) Origin’s ability to maintain important customer relationships, reputation or otherwise avoid liquidity risks; (16) increasing costs as Origin grows deposits; (17) operational risks associated with Origin’s business; (18) significant turbulence or a disruption in the capital or financial markets and the effect of market disruption and interest rate volatility on our investment securities; (19) increased competition in the financial services industry, particularly from regional and national institutions, as well as from fintech companies; (20) compliance with governmental and regulatory requirements and changes in laws, rules, regulations, interpretations or policies relating to financial institutions; (21) periodic changes to the extensive body of accounting rules and best practices; (22) further government intervention in the U.S. financial system; (23) a deterioration of the credit rating for U.S. long-term sovereign debt; (24) Origin’s ability to comply with applicable capital and liquidity requirements, including its ability to generate liquidity internally or raise capital on favorable terms, including continued access to the debt and equity capital markets; (25) natural disasters and other adverse weather events, pandemics, acts of terrorism, war, and other matters beyond Origin’s control; (26) developments in our mortgage banking business, including loan modifications, general demand, and the effects of judicial or regulatory requirements or guidance; (27) fraud or misconduct by internal or external actors (including Origin employees); (28) cybersecurity threats or security breaches and the cost of defending against them; (29) Origin’s ability to maintain adequate internal controls over financial and non-financial reporting; and (30) potential claims, damages, penalties, fines, costs and reputational damage resulting from pending or future litigation, regulatory proceedings and enforcement actions. For a discussion of these and other risks that may cause actual results to differ from expectations, please refer to the sections titled “Cautionary Note Regarding Forward-Looking Statements” and “Risk Factors” in Origin’s most recent Annual Report on Form 10-K filed with the Securities and Exchange Commission and any updates to those sections set forth in Origin’s subsequent Quarterly Reports on Form 10-Q and Current Reports on Form 8-K. If one or more events related to these or other risks or uncertainties materialize, or if Origin’s underlying assumptions prove to be incorrect, actual results may differ materially from what Origin anticipates. Accordingly, you should not place undue reliance on any forward-looking statements. Any forward-looking statement speaks only as of the date on which it is made, and Origin does not undertake any obligation to publicly update or review any forward-looking statement, whether as a result of new information, future developments or otherwise. New risks and uncertainties arise from time to time, and it is not possible for Origin to predict those events or how they may affect Origin. In addition, Origin cannot assess the impact of each factor on Origin’s business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward- looking statements. All forward-looking statements, expressed or implied, included in this communication are expressly qualified in their entirety by this cautionary statement. This cautionary statement should also be considered in connection with any subsequent written or oral forward-looking statements that Origin or persons acting on Origin’s behalf may issue. Annualized, pro forma, adjusted, projected, and estimated numbers are used for illustrative purposes only, are not forecasts, and may not reflect actual results. This presentation contains projected financial information with respect to Origin, including with respect to certain goals and strategic initiatives of Origin and the anticipated benefits thereof. This projected financial information constitutes forward-looking information and is for illustrative purposes only and should not be relied upon as necessarily being indicative of future results. The assumptions and estimates underlying such projected financial information are inherently uncertain and are subject to significant business, economic (including interest rate), competitive, and other risks and uncertainties. Actual results may differ materially from the results contemplated by the projected financial information contained herein and the inclusion of such projected financial information in this presentation should not be regarded as a representation by any person that such actions will be taken or accomplished or that the results reflected in such projected financial information with respect thereto will be achieved. Origin reports its results in accordance with generally accepted accounting principles in the United States ("GAAP"). However, management believes that certain supplemental non-GAAP financial measures may provide meaningful information to investors that is useful in understanding Origin's results of operations and underlying trends in its business. However, non-GAAP financial measures are supplemental and should be viewed in addition to, and not as an alternative for, Origin's reported results prepared in accordance with GAAP. The following are the non-GAAP measures used in this presentation: Pre-tax, pre-provision (“PTPP”) earnings, PTPP ROAA, tangible book value per common share, adjusted tangible book value per common share, tangible common equity to tangible assets, return on average tangible common equity and core efficiency ratio. Please see “Reconciliation of Non-GAAP Financial Measures” at the end of this presentation for reconciliations of non-GAAP measures to the most directly comparable financial measures calculated in accordance with GAAP.

ORIGIN BANCORP, INC. _______ • Optimize Origin - Our newly announced initiative to drive elite financial performance and enhance our award- winning culture. • Our NIM-FTE increased 15 bps for 4Q24, compared to 3Q24. This was driven primarily by a 40 bp reduction in rates paid on interest-bearing liabilities, offset by an 18 bp decline in our yield on interest-earning assets. • Net interest income was $78.3 million for 4Q24, reflecting an increase of $3.5 million, or 4.7%, compared to 3Q24 and is at its highest level in two years. • Provision for credit loss benefit was $5.4 million at 4Q24, compared to a provision for credit loss expense of $4.6 million in 3Q24. • Our bond portfolio optimization strategy, aimed at enhancing long-term yields and improving overall portfolio performance, positively impacted our NIM-FTE by 3 bps for 4Q24, and is estimated to provide a total annual positive impact to NIM-FTE of 7 bps. We sold AFS investment securities with a book value of $188.2 million and realized a loss of $14.6 million, which negatively impacted our diluted EPS by $0.37 for 4Q24.

(3) Excludes notable items. (4) Data obtained from United States Census Bureau (census.gov), Texas Comptroller (comptroller.texas.gov), Office of the Texas Governor (gov.texas.gov), Fortune (fortune.com), Bureau of Labor Statistics (bls.gov), Baldwin County Economic Development Council (baldwineda.com), Florida's Great Northwest (floridasgreatnorthwest.com), Bureau of Transportation Statistics (bts.gov) and Port of Mobile, Alabama Port Authority (alports.com). (5) As used in this presentation, PTPP earnings, PTPP ROAA, tangible book value per common share, adjusted tangible book value per common share, tangible common equity to tangible assets, ROATCE, and core efficiency ratio are either non-GAAP financial measures or use a non-GAAP contributor in the formula. For a reconciliation of these alternative financial measures to their comparable GAAP measures, see slides 27-30 of this presentation. (6) Total LHFI, adjusted excludes MW LOC for all periods presented. (7) Origin Bancorp, Inc. and KBW Nasdaq Bank cumulative total shareholder return assumes $100 invested on December 31, 1996, and any dividends are reinvested. Data for Origin Bancorp, Inc. cumulative total shareholder return prior to May 9, 2018, is based upon private stock transactions and is not reflective of open market trades. (8) Data obtained from The United States Census Bureau (census.gov). Count is as of most recent practicable date. The Company expects to close six banking centers in February 2025 in conjunction with its Optimize Origin initiative. (9) Prior period numbers were adjusted to include mortgage warehouse deposits in our DFW market. (10) Periods ended December 31, 2020 and 2021, exclude PPP loans. (11) Does not include loans held for sale. (12) The ALCL to total LHFI, adjusted is calculated by excluding the ALCL for MW LOC from the total LHFI ALCL in the numerator and excluding the MW LOC from the LHFI in the denominator. Due to their low-risk profile, MW LOC require a disproportionately low allocation of the ALCL. (13) The sensitivity analysis is based on loans exceeding $2.5 million. (14) Represents an interest rate sensitivity test for CRE non-owner office loans over $2.5 million using interest rate assumptions increased to 8.0% for 2024 maturities, 7.4% for 2025 maturities, 6.4% for 2026 maturities, 5.9% for 2027 maturities and 5.9% for 2028+ maturities, based upon federal open market committee projections at September 2024. (15) Represents the weighted average loan to value based upon an increase to a 10% stress capitalization rate on loans exceeding $2.5 million within the CRE non-owner occupied office portfolio. (16) The accumulated other comprehensive loss primarily represents the unrealized loss, net of tax benefit, of available for sale securities and is a component of equity. (17) Floating rate loans typically reprice monthly, while variable rate loans reprice based upon the terms defined within the adjustable rate loan agreement specific to their loan contract. (18) Projection is based upon December 31, 2024, time deposit balances. (19) Mortgage banking revenue for 1Q24 and 4Q23 was adjusted by removing the impact for the $410,000 gain on sale and $1.8 million impairment, respectively, on the MSR portfolio. (20) December 31, 2024, dollars and ratios are estimated. (21) Capital ratios including AOCI are calculated by including the accumulated other comprehensive loss used in the numerator of the respective ratios and including the primarily negative fair value adjustments on the available for sale portfolio in the total risk-weighted assets used in the denominator of the ratio. (22) The diluted EPS impact is calculated using a 21% effective tax rate. The total of the diluted EPS impact of each individual line item may not equal the calculated diluted EPS impact on the total notable items due to rounding.
