*For Immediate Release*

**ORIGIN BANCORP, INC. REPORTS EARNINGS FOR SECOND QUARTER 2025**

**RUSTON, Louisiana (July 23, 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 $14.6 million, or $0.47 diluted earnings per share ("EPS") for the quarter ended June 30, 2025, compared to net income of $22.4 million, or $0.71 diluted earnings per share, for the quarter ended March 31, 2025. Pre-tax, pre-provision ("PTPP")<sup>(1)</sup> earnings were $21.5 million for the quarter ended June 30, 2025, compared to $32.0 million for the linked quarter.

"During the second quarter, we continued to successfully execute on ***Optimize Origin***, our plan to deliver elite level financial performance for Origin and our shareholders," said Drake Mills, chairman, president and CEO of Origin Bancorp, Inc. "Throughout the first half of the year, we have created efficiencies within our branch network, improved the overall profitability of our commercial banking team, restructured our mortgage business, and taken multiple actions to optimize our balance sheet. As we head into the back half of 2025, we are well-positioned in the nation's most dynamic growth markets; and I have full confidence that our employees will continue delivering exceptional value to our customers, communities, and shareholders."

<sup>(1)</sup> 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***

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• In January 2025, we announced our initiative to drive elite financial performance and enhance our award-winning culture.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Built on three primary pillars:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**◦** Productivity, Delivery & Efficiency

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**◦** Balance Sheet Optimization

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**◦** Culture & Employee Engagement

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Established near term target of greater than a 1% ROAA run rate by 4Q25 and an ultimate target of top quartile ROAA.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We believe the actions we have taken will drive earnings improvement of approximately $34.2 million annually on a pre-tax pre-provision basis - an increase of approximately $10.8 million since the last quarterly update, due to additional benefits from increasing our Argent Financial ownership and further securities portfolio optimization.

**Financial Highlights**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Net interest income was $82.1 million for the quarter ended June 30, 2025, reflecting an increase of $3.7 million, or 4.7%, compared to the linked quarter and is at its highest level in the previous nine quarters.

------

<sup>`</sup>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Our fully tax equivalent net interest margin ("NIM-FTE") expanded 17 basis points to 3.61% for the quarter ended June 30, 2025, compared to the quarter ended March 31, 2025. The increase was primarily driven by an eight-basis point increase in the yield earned on average interest-earning assets and a five-basis point decline in the rate paid on average interest-bearing liabilities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• As part of our bond portfolio optimization strategy, we sold available-for-sale investment securities with a book value of $215.8 million and realized a loss of $14.4 million during the quarter ended June 30, 2025. This transaction, net of the increase in interest income, negatively impacted diluted EPS by $0.35, but contributed approximately two basis points to our NIM-FTE for the quarter ended June 30, 2025, with an estimated twelve-month total positive impact to NIM-FTE of six basis points.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Total loans held for investment ("LHFI") were $7.68 billion at June 30, 2025, reflecting an increase of $98.9 million, or 1.3%, compared to March 31, 2025. LHFI, excluding mortgage warehouse lines of credit ("MW LOC"), were $7.11 billion at June 30, 2025, reflecting a decrease of $71.7 million, or 1.0%, compared to March 31, 2025.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• During the quarter ended June 30, 2025, we repurchased 136,399 shares of our common stock at an average price of $31.84 per share. Also, in July 2025, our board of directors approved a stock repurchase program authorizing the purchase of up to $50.0 million of the Company's outstanding common stock over the next three years, replacing the existing plan which expires this month.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Book value per common share was $38.62 at June 30, 2025, reflecting an increase of $0.85, or 2.3%, compared to March 31, 2025 and $3.39, or 9.6%, compared to June 30, 2024. Tangible book value per common share<sup>(1)</sup> was $33.33 at June 30, 2025, reflecting an increase of $0.90, or 2.8%, compared to March 31, 2025 and $3.56, or 12.0%, compared to June 30, 2024.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• As part of our *Optimize Origin* initiatives, we purchased additional shares of Argent Financial on July 1, 2025, which allowed us to reach the 20% ownership threshold. This will change our accounting methodology on this investment to the equity method, which will result in an increase in noninterest income.

<sup>(1)</sup> Tangible book value per common share 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.

**Results of Operations for the Quarter Ended June 30, 2025**

**Net Interest Income and Net Interest Margin**

Net interest income for the quarter ended June 30, 2025, was $82.1 million, an increase of $3.7 million, or 4.7%, compared to the quarter ended March 31, 2025. The increase was primarily driven by a $4.1 million increase in interest income earned on LHFI and decreases of $1.6 million and $1.1 million in interest expense paid on interest-bearing deposits and subordinated debentures, respectively, partially offset by a $3.0 million decrease in interest income earned on interest-earning balances due from banks and a $1.1 million increase in interest expense on FHLB advances and other borrowings.

The increase in average LHFI principal balances and the impact of one more calendar day during the quarter ended June 30, 2025, resulted in interest income increases of $3.1 million and $1.3 million, respectively, when compared to the quarter ended March 31, 2025. The increase in average LHFI principal balances was primarily driven by increases of $191.1 million and $64.1 million in MW LOC and commercial and industrial loans, respectively, partially offset by a decrease of $77.1 million in total average real estate loan balances.

The $1.6 million decrease in interest expense on interest-bearing deposits was mainly due to a $232.8 million decrease in average interest-bearing deposits balance, during the quarter ended June 30, 2025, when compared to the quarter ended March 31, 2025. Due primarily to the seasonality of the deposits, interest-bearing public fund average deposit balances decreased $163.5 million during the quarter ended June 30, 2025.

The $1.1 million decrease in interest expense on subordinated debentures was primarily driven by the redemption of $70.0 million in subordinated debentures during the quarter ended March 31, 2025, in conjunction with our *Optimize Origin* initiatives.

The $3.0 million decrease in interest income earned on average interest-earning balances due from banks was primarily driven by a $267.4 million decrease in average interest-earning balances due from banks.

------

<sup>`</sup>

The $97.8 million increase in average FHLB advances and other borrowings balance contributed $664,000 to the total $1.1 million increase in interest expense on FHLB advances and other borrowings during the quarter ended June 30, 2025. The remaining increase was primarily driven by an increase in the average rate paid on FHLB advances and other borrowings rising to 4.36% for the quarter ended June 30, 2025, from 2.75% for the quarter ended March 31, 2025. The average short-term FHLB balances were $98.4 million for the quarter ended June 30, 2025, compared to zero for the quarter ended March 31, 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 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. In total, the federal funds target range has decreased 100 basis points from its recent cycle high.

Our NIM-FTE was 3.61% for the quarter ended June 30, 2025, representing 17- and 44-basis-point increases compared to the linked quarter and the quarter ended June 30, 2024, respectively. The yield earned on interest-earning assets for the quarter ended June 30, 2025, was 5.87%, an increase of eight basis points compared to the linked quarter and a decrease of 17 basis points compared to the quarter ended June 30, 2024. The average rate paid on total interest-bearing liabilities for the quarter ended June 30, 2025, was 3.25%, representing a decrease of five- and 73-basis points compared to the linked quarter and the quarter ended June 30, 2024, respectively. Additionally, total loans represented 83.6% of average interest-earning assets during the quarter ended June 30, 2025, up from 80.8% during the quarter ended March 31, 2025, providing a favorable shift in the asset mix that contributed to the margin improvement.

During the quarter ended June 30, 2025, 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 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 $215.8 million and a weighted average yield of 2.60% with new securities totaling $201.8 million with a weighted average yield of 5.23%, realizing a loss of $14.4 million. The weighted average duration of the securities portfolio increased to 4.52 years as of June 30, 2025, compared to 4.10 years as of March 31, 2025. As part of the strategy, we also entered into interest rate swaps designated as fair value hedges on seven of these purchased securities with a total book value of $41.3 million, to help reduce potential volatility in the fair value of these securities due to changes in market rates. While this transaction resulted in a $0.35 negative impact to diluted EPS during the quarter ended June 30, 2025, due to the realized loss net of the increase in interest income, we believe the trade-off in yield represents an attractive opportunity. This transaction is expected to generate an estimated annual increase in net interest income of $5.6 million, with an estimated earn-back period of 2.6 years and an estimated twelve-month total positive impact to NIM-FTE of six basis points. We will continue to evaluate and identify any additional opportunities that may present themselves to maximize our return on our securities portfolio.

___________________________

N/A = Not applicable.

<sup>(1)</sup> Past due LHFI are defined as loans 30 days or more past due and includes past due nonperforming loans.

<sup>(2)</sup> Please see the *Loan Data* schedule at the back of this document for additional information.

<sup>(3)</sup> 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.

Loans past due 30-89 days and still accruing decreased $30.1 million for the current quarter compared to the linked quarter. The decrease was primarily driven by three loan relationships totaling $10.7 million that were paid off in the current quarter. Also contributing to the decrease in loans 30-89 days past due and still accruing were three loan relationships that are now over 90 days past due and nonperforming totaling $10.6 million and two loan relationships that are now no longer past due totaling $3.0 million.

Nonperforming LHFI increased $3.9 million for the current quarter compared to the linked quarter, evidenced by an increase in the percentage of nonperforming LHFI to LHFI to 1.11% compared to 1.07% for the linked quarter. The increase in nonperforming loans was primarily driven by four relationships totaling $12.9 million at June 30, 2025. The increase was partially offset by $3.6 million in payments from two relationships and further reduced by total charge-offs of $2.9 million.

Our results included a credit loss provision expense of $2.9 million during the quarter ended June 30, 2025, which includes a $2.7 million provision for loan credit losses, compared to provision for loan credit losses of $3.7 million for the linked quarter. Net charge-offs decreased $428,000 for the quarter ended June 30, 2025, when compared to the quarter ended March 31, 2025, primarily due to total charge-offs of $4.8 million in the linked quarter, consisting primarily of two commercial and industrial loan relationships with charge-offs totaling $2.6 million, with no comparably sized charge-offs during the current quarter.

**Noninterest Income**

Noninterest income for the quarter ended June 30, 2025, was $1.4 million, a decrease of $14.2 million, or 91.2%, from the linked quarter, primarily driven by a $14.4 million loss on sales of securities, net, and a $1.3 million decrease in insurance commission and fee income, respectively, in the current quarter. These decreases were partially offset by an increase of $902,000 in swap fee income.

The loss on sales of securities, net, during the current quarter was due to the execution of the bond portfolio optimization strategy discussed above.

------

<sup>`</sup>

The decrease in insurance commission and fee income was primarily driven by a seasonal increase in annual contingency fee income recognized in the first quarter with no comparable increase in the current quarter.

The increase in swap fee income was due to both an attractive interest rate environment which is increasingly conducive to facilitating back-to-back swaps for our customers and an increased focus on the marketing of customer swaps as part of *Optimize Origin*.

**Noninterest Expense**

Noninterest expense for the quarter ended June 30, 2025, was $62.0 million, a decrease of $85,000, or 0.1% from the linked quarter. The decrease was primarily driven by a decrease of $1.4 million in occupancy and equipment, net, that was partially offset by increases of $549,000 and $475,000 in salaries and employee benefit expense and data processing expense, respectively.

The $1.4 million decrease in occupancy and equipment, net was primarily due to cost incurred in the linked quarter in connection with the closure of banking centers as a part of *Optimize Origin*.

The $549,000 increase in salaries and employee benefit expense was primarily due to the adjustment of the incentive compensation accrual which drove the salaries and employee benefit expense lower during the linked quarter.

The $475,000 increase in data processing expense was primarily due to higher loan workflow software costs during the current quarter compared to the linked quarter.

**Financial Condition**

*Loans*

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Total LHFI at June 30, 2025, were $7.68 billion, an increase of $98.9 million, or 1.3%, from $7.59 billion at March 31, 2025, and a decrease of $274.7 million, or 3.5%, compared to June 30, 2024.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The primary drivers of the increase during the quarter ended June 30, 2025, compared to the linked quarter, were increases in MW LOC, multi-family real estate and owner occupied commercial real estate of $170.6 million, $40.1 million and $34.8 million, respectively. These increases were partially offset by decreases of $144.9 million and $10.9 million in construction/land/land development loans and commercial and industrial loans, respectively.

*Securities*

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Total securities at June 30, 2025 were $1.14 billion, a decrease of $34.9 million, or 3.0%, from $1.18 billion at March 31, 2025, and a decrease of $34.1 million, or 2.9%, compared to June 30, 2024.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The decrease in securities was primarily due to maturities of short-term investments and net sales of available for sale securities during the current quarter.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• In connection with *Optimize Origin*, we made a strategic decision to replace lower yielding available-for-sale securities with a total book value of $215.8 million with higher-yielding securities totaling $201.8 million. Additional details about this transaction is disclosed above in the *Net Interest Income and Net Interest Margin* section of this release.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;***•*** Accumulated other comprehensive loss, net of taxes, primarily associated with unrealized losses within the available for sale portfolio, was $73.6 million at June 30, 2025, a decrease of $16.9 million, or 18.6%, from the linked quarter.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The weighted average effective duration for the total securities portfolio was 4.52 years as of June 30, 2025, compared to 4.10 years as of March 31, 2025.

*Deposits*

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Total deposits at June 30, 2025, were $8.12 billion, a decrease of $215.4 million, or 2.6%, compared to March 31, 2025, and a decrease of $387.8 million, or 4.6%, from June 30, 2024. Seasonality in our public fund deposits drove $99.7 million of the current quarter decline when compared to March 31, 2025.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The decrease in total deposits at June 30, 2025, compared to the linked quarter was primarily due to decreases of $159.0 million, $57.3 million and $47.1 million in interest-bearing demand deposits, time deposits (excluding brokered time deposits) and noninterest-bearing deposits, respectively. The decrease was partially offset by an increase of $92.6 million in money market deposits.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• At June 30, 2025 and March 31, 2025, noninterest-bearing deposits as a percentage of total deposits were 22.7%. At June 30, 2024, noninterest-bearing deposits as a percentage of total deposits were 21.9%.

**Non-GAAP Financial Measures** 

Origin reports its results in accordance with generally accepted accounting principles in the United States of America ("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 release: PTPP earnings, PTPP ROAA, tangible book value per common share, ROATCE, and core efficiency ratio.

Please see the last few pages of this release for reconciliations of non-GAAP measures to the most directly comparable financial measures calculated in accordance with GAAP.

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.

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.

____________________________

<sup>(1)</sup> 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.

<sup>(2)</sup> Includes multi-family real estate.

<sup>(3)</sup> Past due LHFI are defined as loans 30 days or more past due and includes past due nonperforming loans.

<sup>(4)</sup> 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.

![](a06_30x2025obkinvestorpr002.jpg)

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. Statements or statistics preceded by, followed by or that otherwise include the words "assumes," "anticipates," "believes," "estimates," "expects," "foresees," "intends," "plans," "projects," and similar expressions or future or conditional verbs such as "could," "may," "might," "should," "will," and "would" and variations of such terms are generally forward-looking in nature and not historical facts, although not all forward-looking statements include the foregoing words. 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 17 bps for 2Q25, compared to 1Q25. This was driven primarily by an 8-bp increase in our yield on interest-earning assets and a 5-bp reduction in rates paid on interest-bearing liabilities. • Net interest income was $82.1 million for 2Q25, reflecting an increase of $3.7 million, or 4.7%, compared to 1Q25 and is at its highest level in the previous nine quarters. • As part of our bond portfolio optimization strategy, we sold available-for-sale investment securities with a book value of $215.8 million and realized a loss of $14.4 million during the quarter ended June 30, 2025. This transaction contributed approximately 2 bps to our NIM-FTE for the quarter ended June 30, 2025, with an estimated total benefit of 6 bps over the next twelve months. • During the quarter ended June 30, 2025, we repurchased 136,399 shares of our common stock at an average price of $31.84 per share.

ORIGIN BANCORP, INC. _______ 30 PRESENTATION NOTES (1) Excludes the Southeast market which is less than 1% of total deposits and loans each. (2) Excludes Treasury/wholesale deposits of $23.9 million at June 30, 2025. (3) Excludes mortgage warehouse lines of credit ("mortgage warehouse LOC"). (4) Excludes notable items. (5) Annualized benefit is presented on a tax-equivalent yield basis to account for tax-exempt income. (6) Data obtained from Office of the Texas Governor (gov.texas.gov), 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). (7) As used in this presentation, PTPP earnings, PTPP ROAA, 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 26-29 of this presentation. (8) Total LHFI, adjusted excludes mortgage warehouse LOC for all periods presented. (9) 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. (10) Data obtained from The United States Census Bureau (census.gov). Count is as of most recent practicable date. (11) Prior period numbers were adjusted to include mortgage warehouse deposits in our DFW market. (12) The DFW and Houston markets include $108.0 million of deposits in total that were sold on December 31, 2024, and immediately repurchased on January 1, 2025. (13) The period ended December 31, 2021, excludes PPP loans. (14) Does not include loans held for sale. (15) The ALCL to total LHFI, adjusted is calculated by excluding the ALCL for mortgage warehouse LOC from the total LHFI ALCL in the numerator and excluding the mortgage warehouse LOC from the LHFI in the denominator. Due to their low-risk profile, mortgage warehouse LOC require a disproportionately low allocation of the ALCL. (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.
