Results of Operations for the Three Months Ended September 30, 2024

Net Interest Income and Net Interest Margin

Net interest income for the quarter ended September 30, 2024, was $74.8 million, an increase of $914,000, or 1.2%, compared to the quarter ended June 30, 2024, $813,000 of which was driven by one additional day in the current quarter. Higher interest rates drove a net increase of $147,000 in net interest income, which was reflected in a $1.2 million increase in interest income earned on interest-earnings assets offset by a $1.1 million increase in interest expense paid on interest-bearing liabilities.

Higher interest rates on LHFI drove a $2.0 million increase in the yield for the quarter ended September 30, 2024, compared to the quarter ended June 30, 2024, $1.5 million of which was driven by real estate-based loans. The average rate on LHFI increased to 6.67% for the quarter ended September 30, 2024, compared to 6.58% for the quarter ended June 30, 2024. Higher interest rates on savings and interest-bearing transaction accounts drove a $1.1 million increase in interest expense, compared to the quarter ended June 30, 2024. The average rate on interest-bearing deposits increased to 4.01% for the quarter ended September 30, 2024, compared to 3.95% for the quarter ended June 30, 2024.

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. The federal funds target rate range was reduced by 50 basis points on September 18, 2024, to a range of 4.75% to 5.00%, the first rate reduction since early 2020.

The NIM-FTE was 3.18% for the quarter ended September 30, 2024, representing a one- and a four-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 September 30, 2024, was 6.09%, an increase of five and 40 basis points compared to the linked quarter and the prior year same quarter, respectively. The average rate paid on total interest-bearing liabilities for the quarter ended September 30, 2024, was 4.04%, representing a six- and 45-basis point increase compared to the linked quarter and the prior year same quarter, respectively.

As discussed in our June 30, 2024, Origin Bancorp, Inc. Earnings Release, we reversed $1.2 million of accrued loan interest during the quarter ended June 30, 2024, due to certain questioned activity involving a single banker, who has since been terminated, in our East Texas market. This reversal of accrued loan interest income negatively impacted the fully tax equivalent net interest margin (“NIM-FTE”) by five basis points for the linked quarter. Had we not experienced the reversal of the $1.2 million of accrued interest income during the quarter ended June 30, 2024, our NIM-FTE would have been 3.22% for the linked quarter, and we would have experienced a four-basis point decrease in our current NIM-FTE compared to the linked quarter. There was no equivalent interest income reversal during the current quarter and these loans remain on non-accrual..

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 in our June 30, 2024, Origin Bancorp, Inc. Earnings Release, our credit metrics were negatively impacted by certain questioned activity involving a single banker, who has since been terminated, in our East Texas market. Our investigation of this activity remains ongoing and is not final; however, as a result of a forbearance agreement with one of our impacted customer relationships, our past due LHFI declined $26.4 million when compared to the quarter ended June 30, 2024. There was no material change in the level of our nonperforming or classified LHFI principal balances between the current quarter and the linked quarter as a result of the questioned activity. We continue to work with an outside forensic accounting firm to confirm the bank’s identification and reconciliation of the activity, targeting a conclusion of this analysis by the end of this year. At this time, we believe that any ultimate loss arising from the situation will not be material to our financial position.

Past due LHFI were $38.8 million for the quarter ended September 30, 2024, compared to $66.3 million at June 30, 2024. Of the $27.4 million decrease, $26.4 million were impacted by or related to the questioned activity. The remaining net decrease in past due LHFI was primarily due to charge-offs or payoffs in commercial and industrial past due loans during the quarter ended September 30, 2024.

Nonperforming LHFI decreased $11.5 million for the quarter reflecting a decrease in the percentage of nonperforming LHFI to LHFI to 0.81% compared to 0.95% for the linked quarter. The decrease in nonperforming loans was primarily driven by three commercial and industrial loan relationships totaling $14.6 million at June 30, 2024, $10.4 million of which were charged-off and $4.2 million were paid down during the current quarter.

Classified loans decreased $10.8 million to $107.5 million at September 30, 2024, reflecting 1.35% as a percentage of total LHFI, down 14 basis points from the linked quarter. The decrease in classified loans was primarily driven by the same three commercial and industrial loan relationships mentioned in the nonperforming loan paragraph directly above.

Noninterest Income

Noninterest income for the quarter ended September 30, 2024, was $16.0 million, a decrease of $6.5 million, or 28.8%, from the linked quarter. The decrease from the linked quarter was primarily driven by decreases of $5.2 million, $725,000 and $621,000 in the change in fair value of equity investments, mortgage banking revenue and other income, respectively.

The decrease in change in fair value of equity investments was due to a $5.2 million positive valuation adjustment on a non-marketable equity security recognized during the linked quarter with no comparable amount recognized during the current quarter.

The decrease in mortgage banking revenue was primarily due to an $833,000 combined decrease in the pipeline and interest rate lock commitment fair values during the current quarter compared to the linked quarter.

The decrease in other income was primarily due to an $818,000 gain on sale of bank property recognized in the linked quarter with no comparable amount recognized in the current quarter.

Noninterest Expense

Noninterest expense for the quarter ended September 30, 2024, was $62.5 million, a decrease of $1.9 million, or 2.9% from the linked quarter. The decrease was primarily driven by a decrease of $1.6 million and in other noninterest expense.

The decrease in other expenses resulted from recognizing contingent liabilities totaling approximately $1.2 million related to certain questioned activity involving a single banker, who has since been terminated, in our East Texas market, as described previously, in the linked quarter with no comparable liability incurred in the current quarter. Also, contributing to the quarter over quarter decline was a $357,000 decrease in corporate membership fees.

Financial Condition

Loans

•Total LHFI were $7.96 billion at both September 30, 2024, and June 30, 2024, and reflected an increase of $388.7 million, or 5.1%, compared to September 30, 2023.

•Total LHFI, excluding MW LOC, were $7.46 billion at September 30, 2024, representing an increase of $8.9 million, or 0.1%, from June 30, 2024, and an increase of $179.8 million, or 2.5%, from September 30, 2023.

•During the quarter ended September 30, 2024, compared to the linked quarter, we experienced declines in construction/land/land development loans and MW LOC of $25.8 million and $11.3 million, respectively, partially offset by growth in multi-family real estate loans of $36.1 million.

Securities

•Total securities were $1.18 billion at both September 30, 2024, and June 30, 2024, and reflected a decrease of $129.8 million, or 9.9%, compared to September 30, 2023.

•Accumulated other comprehensive loss, net of taxes, primarily associated with the available for sale (“AFS”) portfolio, was $94.2 million at September 30, 2024, an improvement of $32.9 million, or 25.9%, from the linked quarter.

•The weighted average effective duration for the total securities portfolio was 4.21 years as of September 30, 2024, compared to 4.28 years as of June 30, 2024.

Deposits

The decrease in the current quarter compared to the linked quarter was primarily due to a decrease of $205.2 million in brokered (which includes both brokered time and brokered interest-bearing demand) deposits. The decrease in brokered deposits was primarily replaced with customer deposits.

•Excluding brokered deposits, total deposit increased $180.9 million, or 2.3%, to $8.05 billion, primarily due to increases of $87.0 million, $64.4 million and $27.1 million in money market deposits, interest-bearing demand deposits and noninterest-bearing demand deposits, respectively.

•At September 30, 2024, noninterest-bearing deposits as a percentage of total deposits were 22.3%, compared to 21.9% and 24.0% at June 30, 2024, and September 30, 2023, respectively. Excluding brokered deposits, noninterest-bearing deposits as a percentage of total deposits were 23.5%, compared to 23.7% and 26.1% at June 30, 2024, and September 30, 2023, respectively.

Borrowings

•FHLB advances and other borrowings at September 30, 2024, were $30.4 million, a decrease of $10.3 million, or 25.3%, compared to the linked quarter and represented an increase of $18.2 million, or 149.3%, from September 30, 2023.

•The increase in stockholders’ equity from the linked quarter is primarily due to a decrease in accumulated other comprehensive loss of $32.9 million and net income of $18.6 million, partially offset by dividends declared of $4.8 million during the current quarter.

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, adjusted NIM-FTE, 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.

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.

(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.

3Q TWENTY24 INVESTOR PRESENTATION ORIGIN BANCORP, INC.

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" 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 the Company's future results and cause actual results to differ materially from those expressed in the forward-looking statements include, but are not limited to: 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 effects of declines in the real estate market, high-profile bank failures, high unemployment rates, inflationary pressures, elevated interest rates and slowdowns in economic growth, as well as the financial stress on borrowers and changes to customer and client behavior as a result of the foregoing; changes in benchmark interest rates and the resulting impacts on net interest income; deterioration of Origin's asset quality; factors that can impact the performance of Origin's loan portfolio, including real estate values and liquidity in Origin's primary market areas; the financial health of Origin's commercial borrowers and the success of construction projects that Origin finances; changes in the value of collateral securing Origin's loans; developments in our mortgage banking business, including loan modifications, general demand, and the effects of judicial or regulatory requirements or guidance; Origin's ability to anticipate interest rate changes and manage interest rate risk (including the impact of higher interest rates on macroeconomic conditions, competition, and the cost of doing business and the impact of prolonged elevated interest rates on our financial projections, models and guidance); the effectiveness of Origin's risk management framework and quantitative models; 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; the impact of labor pressures; changes in Origin's operation or expansion strategy or Origin's ability to prudently manage its growth and execute its strategy; changes in management personnel; Origin's ability to maintain important customer relationships, reputation or otherwise avoid liquidity risks; increasing costs as Origin grows deposits; operational risks associated with Origin's business; 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; increased competition in the financial services industry, particularly from regional and national institutions, as well as from fintech companies, difficult market conditions and unfavorable economic trends in the United States generally, and particularly in the market areas in which Origin operates and in which its loans are concentrated; Origin's level of nonperforming assets and the costs associated with resolving any problem loans including litigation and other costs; the credit risk associated with the substantial amount of commercial real estate, construction and land development, and commercial loans in Origin's loan portfolio; changes in laws, rules, regulations, interpretations or policies relating to financial institutions, and potential expenses associated with complying with such regulations; periodic changes to the extensive body of accounting rules and best practices; further government intervention in the U.S. financial system; a deterioration of the credit rating for U.S. long-term sovereign debt or actions that the U.S. government may take to avoid exceeding the debt ceiling; a potential U.S. federal government shutdown and the resulting impacts; compliance with governmental and regulatory requirements, including the Dodd-Frank Wall Street Reform and Consumer Protection Act and others relating to banking, consumer protection, securities, and tax matters; 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; changes in the utility of Origin's non-GAAP liquidity measurements and its underlying assumptions or estimates; possible changes in trade, monetary, and fiscal policies, laws, and regulations and other activities of governments, agencies and similar organizations; natural disasters and adverse weather events, acts of terrorism, an outbreak of hostilities (including the impacts related to or resulting from Russia's military action in Ukraine, or the conflict in Israel and surrounding areas, including the imposition of additional sanctions and export controls, as well as the broader impacts to financial markets and the global macroeconomic and geopolitical environments), regional or national protests and civil unrest (including any resulting branch closures or property damage), widespread illness or public health outbreaks or other international or domestic calamities, and other matters beyond Origin's control; the impact of generative artificial intelligence; fraud or misconduct by internal or external actors (including Origin employees) which Origin may not be able to prevent, detect or mitigate, system failures, cybersecurity threats or security breaches and the cost of defending against them; Origin’s ability to maintain adequate internal controls over financial and non-financial reporting; and 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 ("SEC") 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. Certain prior period amounts have been reclassified to conform to the current year financial statement presentations. These reclassifications did not impact previously reported net income or comprehensive income. 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: 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.

(4) As used in this presentation, PTPP earnings, PTPP ROAA, tangible book value per common share, adjusted tangible book value per common share, adjusted tangible common equity 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 25-28 of this presentation. (5) Total LHFI, adjusted excludes MW LOC for all periods presented. (6) 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. (7) Data obtained from The United States Census Bureau (census.gov). Count is as of most recent practicable date. (8) Periods ended December 31, 2020 and 2021, exclude PPP loans. (9) Does not include loans held for sale. (10) 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. (11) The sensitivity analysis is based on loans exceeding $2.5 million. (12) Represents an interest rate sensitivity test for CRE non-owner office loans over $2.5 million using interest rate assumptions increased to 8.6% for 2024 maturities, 8.1% for 2025 maturities, 7.1% for 2026 maturities, 6.1% for 2027 maturities and 5.8% for 2028+ maturities, based upon federal open market committee projections at June 12, 2024. (13) 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. (14) 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. (15) 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. (16) For purposes of this classification, all reciprocal deposits are classified as commercial deposits. (17) 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. (18) September 30, 2024, dollars and ratios are estimated. (19) 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. (20) 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.
