Exhibit 99.1
For Immediate Release
ORIGIN BANCORP, INC. REPORTS EARNINGS FOR THIRD QUARTER 2025
RUSTON, Louisiana (October 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 $8.6 million, or $0.27 diluted earnings per share (“EPS”) for the quarter ended September 30, 2025, compared to net income of $14.6 million, or $0.47 diluted earnings per share, for the quarter ended June 30, 2025. Pre-tax, pre-provision (“PTPP”)(1) earnings were $47.8 million for the quarter ended September 30, 2025, compared to $21.5 million for the linked quarter.
“I am extremely proud of how we have executed on Optimize Origin and the momentum that has been created throughout our markets,” said Drake Mills, chairman, president and CEO of Origin Bancorp, Inc. “We are ahead of pace on our stated plan and are creating real traction on our goal of being a top quartile ROA performer.”
(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
•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.
(1) Tangible book value per common share and PTPP Earnings are non-GAAP financial measures, please see the last few pages of this document for a reconciliation of this alternative financial measure to its most directly comparable GAAP measure.
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.

(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:

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.

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, including the impact of tariffs, 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 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. 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 release 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.

(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.

2 FORWARD-LOOKING STATEMENTS AND NON-GAAP MEASURES This presentation contains certain forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. 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. Such forward-looking statements are based on various facts and derived utilizing important assumptions and current expectations, estimates and projections about Origin and its subsidiaries, any of which may change over time and some of which may be beyond Origin’s control.

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, including the impact of tariffs, 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, tangible common equity to tangible assets, return on average tangible common equity (“ROATCE”) 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 - Initiative to drive elite financial performance and enhance our award-winning culture. • Our NIM-FTE increased 4 bps for 3Q25, compared to 2Q25. This was driven primarily by a 2-bp increase in our yield on interest-earning assets and a 3-bp reduction in rates paid on interest- bearing liabilities. • Net interest income was $83.7 million for 3Q25, reflecting an increase of $1.6 million, or 1.9%, compared to 2Q25 and is at its highest level in the previous ten quarters. • During the current quarter, and as part of our Optimize Origin initiative, we purchased additional shares of Argent Financial which required us to account for the investment using the equity method. The transaction included a $7.0 million fair value adjustment gain and we recorded $1.2 million in equity method investment income in the 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.
