The consolidated financial statements in this quarterly report on Form 10-Q have not been audited by an independent registered public accounting firm, excluding the figures as of December 31, 2021, but in the opinion of management, reflect all adjustments (which are of a normal recurring nature) necessary for a fair presentation of the Company's financial position and results of operations for the periods presented. These consolidated financial statements of the Company have been prepared in accordance with U.S. GAAP and with the rules and regulations of the Securities and Exchange Commission (the "SEC") for interim financial reporting. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. These consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto for the year ended December 31, 2021, included in the Company's annual report on Form 10-K ("2021 Form 10-K") filed with the SEC. Operating results for the interim periods disclosed herein are not necessarily indicative of results that may be expected for a full year. 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 (loss). Use of Estimates. The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions based on available information that affect the amounts reported in the financial statements and disclosures provided, including the accompanying notes, and actual results could differ. Material estimates, that are particularly susceptible to change, include the allowance for credit losses for loans, off-balance sheet commitments and available for sale securities; fair value measurements of assets and liabilities; and income taxes. Estimates and assumptions are reviewed periodically, and the effects of revisions are reflected in the Company's consolidated financial statements in the period they are deemed necessary. While management uses its best judgment, actual results could differ from those estimates. Acquisition Accounting and Acquired Loans. The Company accounts for its mergers/acquisitions under Financial Accounting Standards Board ("FASB") Accounting Standards Codification (ASC) Topic 805, Business Combinations, which requires the use of the acquisition method of accounting. All identifiable assets acquired, including loans, are recorded at fair value. In accordance with ASC 326, the Company records a discount or premium and also an allowance for credit losses on acquired loans. All purchased loans are recorded at fair value in accordance with the fair value methodology prescribed in FASB ASC Topic 820, Fair Value Measurements. The fair value estimates associated with the loans include estimates related to expected prepayments and the amount and timing of undiscounted expected principal, interest and other cash flows. Purchased loans that have experienced more than insignificant credit deterioration since origination are purchased credit deteriorated (“PCD”) loans. The Company evaluates acquired loans for deterioration in credit quality based on any of, but not limited to, the following: (1) non-accrual status; (2) troubled debt restructured designation; (3) risk ratings of special mention, substandard or doubtful; (4) watchlist credits; and (5) delinquency status, including loans that are current on merger/acquisition date, but had been previously delinquent two times 60 days. An allowance for credit losses is determined using the same methodology as other individually evaluated loans. The Non-PCD model utilizes data from the Banks in order to determine the probability of default and loss given default to be used in the calculation. The initial allowance for credit losses, determined on a collective basis, is allocated to individual loans. The sum of the loan’s purchase price and allowance for credit losses becomes its initial amortized cost basis. The difference between the initial amortized cost basis and the par value of the loan is a non-credit discount or premium, which is amortized or accreted into interest income over the life of the loan. Subsequent changes to the allowance for credit losses are recorded through the provision for credit losses. Effect of Recently Adopted Accounting Standards Accounting Standards Update ("ASU") No. 2021-06, Presentation of Financial Statements (Topic 205), Financial Services —Depository and Lending (Topic 942), and Financial Services — Investment Companies (Topic 946) —Amendments to SEC Paragraphs Pursuant to SEC Final Rule Releases No. 33-10786, Amendments to Financial Disclosures about Acquired and Disposed Businesses, and No. 33-10835, Update of Statistical Disclosures for Bank and Savings and Loan Registrants amends the ASC in order to agree the Codification to the new SEC releases 33-10786 and 33-10835 (the "Releases"). The Releases clearly define whether an acquired or disposed business subsidiary is significant; update, expand and eliminate certain disclosures; eliminate overlap with certain SEC and U.S. GAAP rules; and add a new subpart of Regulation S-K. The ASU is effective upon issuance; however, the SEC release on which the ASU is based is effective for registrants with the first fiscal year ending after December 15, 2021, while Guide 3 will be rescinded effective January 1, 2023. Implementation of this ASU did not materially impact the Company's financial statement disclosures. Effect of Newly Issued But Not Yet Effective Accounting Standards ASU No. 2021-08, Business Combinations (Topic 805) — Accounting for Contract Assets and Contract Liabilities from Contracts with Customers. The amendments in this Update affect accounting for acquired revenue contracts with customers in a business combination by addressing diversity in practice and inconsistency related to recognition of an acquired contract liability and payment terms and their effect on subsequent revenue recognized by the acquirer. The ASU is effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. Implementation of this ASU is not expected to materially impact the Company's financial statements or disclosures. ASU No. 2022-01, Derivatives and Hedging (Topic 815) — Fair Value Hedging - Portfolio Layer Method. The amendments in this Update clarify the accounting for and promote consistency in the reporting of hedge basis adjustments applicable to both a single hedged layer and multiple hedged layers. Additionally, this Update allows entities to elect to apply the portfolio layer method of hedge accounting in accordance with Topic 815. The ASU is effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. Implementation of this ASU is not expected to materially impact the Company's financial statements or disclosures. ASU No. 2022-02, Financial Instruments - Credit Losses (Topic 326) — Troubled Debt Restructurings and Vintage Disclosures. The amendments in this Update eliminate the accounting guidance for TDRs by creditors in Subtopic 310-40, Receivables—Troubled Debt Restructurings by Creditors, while enhancing disclosure requirements for certain loan refinancings and restructurings by creditors when a borrower is experiencing financial difficulty. Specifically, rather than applying the recognition and measurement guidance for TDRs, an entity must apply the loan refinancing and restructuring guidance in paragraphs 310-20-35-9 through 35-11 to determine whether a modification results in a new loan or a continuation of an existing loan. For public business entities, the amendments in this Update require that an entity disclose current-period gross write-offs by year of origination for financing receivables and net investments in leases within the scope of Subtopic 326-20, Financial Instruments—Credit Losses—Measured at Amortized Cost. The ASU is effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. Implementation of this ASU is not expected to materially impact the Company's financial statements or disclosures.

Earnings Per Share

Note 2 - Earnings Per Share

Basic and diluted earnings per common share are calculated using the treasury method. Under the treasury method, basic earnings per share is calculated as net income divided by the weighted average number of common shares outstanding during the period. Diluted earnings per share includes the dilutive effect of additional potential common shares issuable under the Company's stock and incentive compensation plans. Information regarding the Company's basic and diluted earnings per common share is presented in the following table:

Business Combination and Asset Acquisition [Abstract]

Business Combination

Note 3 - Business Combination

On August 1, 2022, the Company completed its previously announced merger with BT Holdings, Inc. (“BTH”), a Texas corporation and the registered bank holding company of BTH Bank, acquiring 100% of the voting equity interests. The Company issued 6,794,910 shares of its common stock, and all outstanding BTH common stock options were converted into options to purchase an aggregate of 611,676 shares of Origin common stock. Based on the closing price of the Company's common stock on July 29, 2022, of $43.07 per share, the aggregate consideration to be paid to holders of BTH common stock in connection with the merger is valued at approximately $307.8 million. Goodwill of $102.6 million was recorded as a result of the transaction. The merger added new markets for expansion and brings complementary businesses together to drive synergies and growth, which are the factors that gave rise to the goodwill recorded. The goodwill will not be deductible for tax purposes.

Including the effects of the known purchase accounting adjustments, as of the merger date, Origin had approximately $9.84 billion in assets, $6.77 billion in loans and $7.99 billion in deposits on a consolidated basis. Origin Bank and BTH Bank, N.A. operated as separate banking subsidiaries of the Company until the merger of the banks, which Origin completed on October 7, 2022, concurrently with the data processing conversion. BTH formerly operated its banking business from 13 locations, primarily in east Texas, each of which now operates as a banking location of Origin Bank.

The purchase price allocation and certain fair value measurements remain preliminary due to the timing of the merger. The Company will continue to review the estimated fair values of loans, deposits and intangible assets, and to evaluate the assumed tax positions and contingencies.

The Company has determined that the merger of the net assets of BTH constitutes a business combination as defined by the ASC Topic 805. Accordingly, the assets acquired and liabilities assumed are presented at their fair values as required. Fair values were determined based on the requirements of ASC Topic 820. In many cases, the determination of these fair values required management to make estimates about discount rates, future expected cash flows, market conditions and other future events that are highly subjective in nature and subject to change.

The following schedule is a preliminary breakdown of the assets acquired and liabilities assumed as of the merger date:


	BT Holdings, Inc.
(Dollars in thousands)	As Recorded by Origin
Assets Acquired:
Cash and cash equivalents	$	69,953

The Company’s operating results include the operating results of the acquired assets and assumed liabilities of BTH subsequent to the merger date.

Acquisition Accounting. The following is a description of the methods used to determine the fair values of significant assets and liabilities acquired as part of a merger or acquisition. The Company elected to use the pushdown accounting method to record the merger.

Loans acquired – Fair values for PCD loans were based on a discounted cash flow methodology that considered factors including the type of loan and related collateral, classification status, fixed or variable interest rate, term of loan and whether or not the loan was amortizing, and current discount rates except when a fair value of collateral approach was applied. The discount rates used for PCD loans were based on current market rates and include adjustments for liquidity concerns. The discount rate does not include a factor for credit losses, as that has been included in the estimated cash flows. Non-PCD loans were grouped together according to similar characteristics and were treated in the aggregate when applying valuation techniques. See Note 5 - Loans in these condensed notes to consolidated financial statements for more information related to loans acquired.

Loan Acquisition Accounting – The Company accounts for its acquisitions/mergers under ASC Topic 805, Business Combinations, which requires the use of the acquisition method of accounting. All identifiable assets acquired, including loans, are recorded at fair value. The fair value for acquired loans at the time of acquisition or merger is based on a variety of factors, including discounted expected cash flows, adjusted for estimated prepayments and credit losses. In accordance with ASC 326, the fair value adjustment is recorded as premium or discount to the unpaid principal balance of each acquired loan. Loans that have been identified as having experienced a more-than-insignificant deterioration in credit quality since origination are PCD loans. The net premium or discount on PCD loans is adjusted by the Company’s allowance for credit losses recorded at the time of merger/acquisition. The remaining net premium or discount is accreted or amortized into interest income over the remaining life of the loan using the effective interest rate method. The net premium or discount on loans that are not classified as PCD (“non-PCD”), that includes credit and non-credit components, is accreted or amortized into interest income over the remaining life of the loan using a constant yield method. The Company then records the necessary allowance for credit losses on the non-PCD loans through provision for credit losses expense.

Purchased loans that reflect a more-than-insignificant deterioration of credit from origination are considered PCD. For PCD loans, the initial estimate of expected credit losses is recognized in the allowance for credit loss on the date of the merger using the same methodology as other loans held for investment as discussed in Note 5 - Loans in these condensed notes to consolidated financial statements. The following table provides a summary of loans purchased with credit deterioration at the merger transaction date with BTH:


	August 1, 2022
(Dollars in thousands)	Commercial Real Estate		Construction/ Land/ Land Development		Residential Real Estate		Commercial and Industrial		Mortgage Warehouse Lines of Credit		Consumer		Total
Unpaid principal balance	$	10,731	$	1,315	$	2,880	$	37,117	$	—	$	169	$	52,212

At September 30, 2022, the Company had 714 individual securities that were in an unrealized loss position. Management evaluates available for sale debt securities in unrealized loss positions to determine whether the impairment is due to credit-related factors or noncredit-related factors. Consideration is given to (1) the extent to which the fair value is less than the cost, (2) the financial condition and near-term prospects of the issuer, and (3) the intent and ability of the Company to retain its investment in the security for a period of time sufficient to allow for any anticipated recovery in fair value.

Management does not have the intent to sell any of the securities in an unrealized loss position and believes that it is more likely than not that the Company will not have to sell any such securities before a recovery of cost. The fair value is expected to recover as the securities approach their maturity date or repricing date or if market yields for such investments decline. Accordingly, at September 30, 2022, management believes that the unrealized losses detailed in the previous table are due to noncredit-related factors, including changes in interest rates and other market conditions, and therefore no losses have been recognized in the Company’s consolidated statements of income.

The following table presents the activity in the allowance for credit losses for held-to-maturity debt securities.

____________________________

(1)Includes purchase accounting adjustment and net deferred loan fees of $15.06 million at September 30, 2022, and net deferred loan fees of $9.6 million at December 31, 2021. There were no merger date loan fair value adjustments at December 31, 2021.

On August 1, 2022, the Company completed the merger with BTH. As of the merger date, BTH had approximately $1.24 billion in loans and the Company recorded a Day 1 fair value purchase accounting net discount of $5.0 million. As of September 30, 2022, the remaining purchase accounting net loan discount was $3.9 million.

Credit quality indicators. As part of the Company's commitment to managing the credit quality of its loan portfolio, management annually and periodically updates and evaluates certain credit quality indicators, which include but are not limited to (i) weighted-average risk rating of the loan portfolio, (ii) net charge-offs, (iii) level of non-performing loans, (iv) level of classified loans (defined as substandard, doubtful and loss), and (v) the general economic conditions in the cities and states in which the Company operates. The Company maintains an internal risk rating system where ratings are assigned to individual loans based on assessed risk. Loan risk ratings are the primary indicator of credit quality for the loan portfolio and are continually evaluated to ensure they are appropriate based on currently available information.

The following is a summary description of the Company's internal risk ratings:


• Pass (1-6)			Loans within this risk rating are further categorized as follows:
Minimal risk (1)			Well-collateralized by cash equivalent instruments held by the Banks.
Moderate risk (2)			Borrowers with excellent asset quality and liquidity. Borrowers' capitalization and liquidity exceed industry norms. Borrowers in this category have significant levels of liquid assets and have a low level of leverage.
Better than average risk (3)			Borrowers with strong financial strength and excellent liquidity that consistently demonstrate strong operating performance. Borrowers in this category generally have a sizable net worth that can be converted into liquid assets within 12 months.
Average risk (4)			Borrowers with sound credit quality and financial performance, including liquidity. Borrowers are supported by sufficient cash flow coverage generated through operations across the full business cycle.
Marginally acceptable risk (5)			Loans generally meet minimum requirements for an acceptable loan in accordance with lending policy, but possess one or more attributes that cause the overall risk profile to be higher than the majority of newly approved loans.
Watch (6)			A passing loan with one or more factors that identify a potential weakness in the overall ability of the borrower to repay the loan. These weaknesses are generally mitigated by other factors that reduce the risk of delinquency or loss.
• Special Mention (7)			This grade is intended to be temporary and includes borrowers whose credit quality has deteriorated and is at risk of further decline.
• Substandard (8)			This grade includes "Substandard" loans under regulatory guidelines. Substandard loans exhibit a well-defined weakness that jeopardizes debt repayment in accordance with contractual agreements, even though the loan may be performing. These obligations are characterized by the distinct possibility that a loss may be incurred if these weaknesses are not corrected and repayment may be dependent upon collateral liquidation or secondary source of repayment.
• Doubtful (9)			This grade includes "Doubtful" loans under regulatory guidelines. Such loans are placed on nonaccrual status and repayment may be dependent upon collateral with no readily determinable valuation or valuations that are highly subjective in nature. Repayment for these loans is considered improbable based on currently existing facts and circumstances.
• Loss (0)			This grade includes "Loss" loans under regulatory guidelines. Loss loans are charged-off or written down when repayment is not expected.

In connection with the review of the loan portfolio, the Company considers risk elements attributable to particular loan types or categories in assessing the quality of individual loans. The list of loans to be reviewed for possible individual evaluation consists of nonaccrual commercial loans over $100,000 with direct exposure, unsecured loans over 90 days past due, commercial loans classified substandard or worse over $100,000 with direct exposure, TDRs, consumer loans greater than $100,000 with a FICO score under 625, loans greater than $100,000 in which the borrower has filed bankruptcy, and all loans 180 days or more past due. Loans under $50,000 will be evaluated collectively in designated pools unless a loss exposure has been identified. Some additional risk elements considered by loan type include:

•for commercial real estate loans, the debt service coverage ratio, operating results of the owner in the case of owner-occupied properties, the loan to value ratio, the age and condition of the collateral and the volatility of income, property value and future operating results typical of properties of that type;

•for construction, land and land development loans, the perceived feasibility of the project, including the ability to sell developed lots or improvements constructed for resale or the ability to lease property constructed for lease, the quality and nature of contracts for presale or prelease, if any, experience and ability of the developer and loan to value ratio;

•for residential mortgage loans, the borrower's ability to repay the loan, including a consideration of the debt to income ratio and employment and income stability, the loan-to-value ratio, and the age, condition and marketability of the collateral; and

•for commercial and industrial loans, the debt service coverage ratio (income from the business in excess of operating expenses compared to loan repayment requirements), the operating results of the commercial, industrial or professional enterprise, the borrower's business, professional and financial ability and expertise, the specific risks and volatility of income and operating results typical for businesses in that category and the value, nature and marketability of collateral.

Purchased loans that have experienced more than insignificant credit deterioration since origination are PCD loans. An allowance for credit losses is determined using the same methodology as other individually evaluated loans. The Company held approximately $51.4 million in PCD loans, at September 30, 2022, as a result of the merger with BTH on August 1, 2022, and none at December 31, 2021.

Please see Note 1 - Significant Accounting Policies in these Condensed Notes to Consolidated Financial Statements for a description of our accounting policies related to purchased financial assets with credit deterioration.

The following table reflects recorded investments in loans by credit quality indicator and origination year at September 30, 2022, excluding loans held for sale and loans accounted for at fair value. Loans acquired are shown in the table by origination year, not merger date. The Company had an immaterial amount of revolving loans converted to term loans at September 30, 2022.

U.S. GAAP requires that a discount or premium, and also an allowance for credit losses be recorded on acquired loans. The Company completed the merger with BTH on August 1, 2022. As a result, the Company recorded $5.0 million in net loan discounts and a $5.5 million increase in the allowance for credit losses related to PCD loans. In addition, the Company recorded a Day 1 $14.9 million provision for loan credit losses on non-PCD loans required by the Current Expected Credit Losses ("CECL") guidance.

The following tables detail activity in the allowance for loan credit losses by portfolio segment. Accrued interest of $21.9 million and $16.3 million was not included in the book value for the purposes of calculating the allowance at September 30, 2022, and September 30, 2021, respectively. Allocation of a portion of the allowance to one category of loans does not preclude its availability to absorb losses in other categories.

The increase in provision expense during the nine months ended September 30, 2022, is primarily due to the merger with BTH, completed on August 1, 2022, which required a Day 1 CECL loan provision of $14.9 million. The allowance for loan credit losses increased $13.4 million compared to September 30, 2021, primarily driven by a $16.6 million increase related to qualitative factor changes across the Company's risk pools for the nine months ended September 30, 2022, of which $11.8 million was due to the loans we acquired as a result of the BTH merger.

The following table presents the amortized cost basis of collateral dependent loans, which are individually evaluated to determine expected credit losses, and the related Allowance for Credit Losses ("ACL") allocated to these loans.

Collateral-dependent loans consist primarily of residential real estate and commercial and industrial loans. These loans are individually evaluated when foreclosure is probable or when the repayment of the loan is expected to be provided substantially through the operation or sale of the underlying collateral. In the case of commercial and industrial loans secured by equipment, the fair value of the collateral is estimated by third-party valuation experts. Loan balances are charged down to the underlying collateral value when they are deemed uncollectible. Note that the Company did not elect to use the collateral maintenance agreement practical expedient available under CECL.

All interest accrued but not received for loans placed on nonaccrual status is reversed against interest income. Subsequent receipts on nonaccrual loans are recorded as a reduction of principal, and interest income is recorded only after principal recovery is reasonably assured. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured. At September 30, 2022 and December 31, 2021, the Company had no funding commitments for which the terms were modified in TDRs.

For the nine months ended September 30, 2022 and 2021, gross interest income, that would have been recorded had the nonaccruing loans been current in accordance with their original terms, was $799,000 and $1.4 million, respectively. No interest income was recorded on these loans while they were considered nonaccrual during the nine months ended September 30, 2022 and 2021.

The Company elects the fair value option for recording residential mortgage loans held for sale in accordance with U.S. GAAP. The Company had $2.7 million of nonaccrual mortgage loans held for sale that were recorded using the fair value option election at September 30, 2022, compared to $1.8 million at December 31, 2021.

Loans classified as TDRs, excluding the impact of forbearances granted due to COVID-19, were as follows:

There were no loans that defaulted during the three or nine months ended September 30, 2022 or 2021, after having been modified as a TDR within the previous 12 months. A payment default is defined as a loan that was 90 or more days past due. The Company monitors the performance of the modified loans to their restructured terms on an ongoing basis. In the event of subsequent default, the allowance for loan credit losses continues to be reassessed on the basis of an individual evaluation of each loan. The modifications made during the three or nine months ended September 30, 2022, and September 30, 2021, did not significantly impact the Company's determination of the allowance for credit losses.

Fair Value of Financial Instruments

Fair Value Disclosures [Abstract]

Fair Value of Financial Instruments

Note 6 - Fair Value of Financial Instruments

Fair value is the exchange price that is expected to be received for an asset or paid to transfer a liability (exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Certain assets and liabilities are recorded in the Company's consolidated financial statements at fair value. Some are recorded on a recurring basis and some on a non-recurring basis.

The Company utilizes fair value measurement to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. The determination of fair values of financial instruments often requires the use of estimates. In cases where quoted market values in an active market are not available, the Company utilizes valuation techniques that are consistent with the market approach, the income approach and/or the cost approach to estimate the fair values of its financial instruments. Such valuation techniques are consistently applied.

A hierarchy for fair value has been established, which categorizes the valuation techniques into three levels used to measure fair value. The three levels are as follows:

Level 1 - Fair value is based on unadjusted quoted prices in active markets for identical assets or liabilities.

Level 2 - Fair value is based on significant other observable inputs that are generally determined based on a single price for each financial instrument provided to the Company by an unrelated third-party pricing service and is based on one or more of the following:

•Quoted prices for similar, but not identical, assets or liabilities in active markets;

•Quoted prices for identical or similar assets or liabilities in markets that are not active;

•Inputs other than quoted prices that are observable, such as interest rate and yield curves, volatilities, prepayment speeds, loss severities, credit risks and default rates; and

•Other inputs derived from or corroborated by observable market inputs.

Level 3 - Prices or valuation techniques that require inputs that are both significant and unobservable in the market. These instruments are valued using the best information available, some of which is internally developed, and reflects the Company's own assumptions about the risk premiums that market participants would generally require and the assumptions they would use. These estimates can be inherently uncertain.

There were no transfers between fair value reporting levels for any period presented.

Fair Values of Assets and Liabilities Recorded on a Recurring Basis

The following tables summarize financial assets and financial liabilities recorded at fair value on a recurring basis at September 30, 2022, and December 31, 2021, segregated by the level of valuation inputs within the fair value hierarchy utilized to measure fair value. There were no changes in the valuation techniques during 2022 or 2021.

___________________________

(1)Total mortgage banking revenue includes changes in fair value due to market changes and run-off.

The Company obtains fair value measurements for loans at fair value, securities available for sale and securities at fair value through income from an independent pricing service; therefore, quantitative unobservable inputs are unknown.

The following methodologies were used to measure the fair value of financial assets and liabilities valued on a recurring basis:

Securities Available for Sale

Securities classified as available for sale are reported at fair value utilizing Level 1, Level 2 or Level 3 inputs. For Level 1 securities, the Company obtains the fair value measurements for those identical assets from an independent pricing service. For Level 2 securities, the Company obtains fair value measurements from an independent pricing service. The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, the U.S. Treasury yield curve, live trading levels, market consensus prepayment speeds, credit information and the security's terms and conditions, among other things. In order to ensure the fair values are consistent with ASC 820, Fair Value Measurements and Disclosures, the Company periodically checks the fair value by comparing them to other pricing sources, such as Bloomberg LP. The third-party pricing service is subject to an annual review of internal controls in accordance with the Statement on Standards for Attestation Engagements No. 16, which was made available to the Company. In certain cases where Level 2 inputs are not available, securities are classified within Level 3 of the hierarchy.

Mortgage Servicing Rights ("MSRs")

The carrying amounts of the MSRs equal fair value, which are determined using a discounted cash flow valuation model. The significant assumptions used to value MSRs were as follows:


	September 30, 2022			December 31, 2021
	Range	Weighted Average(1)		Range	Weighted Average(1)
Prepayment speeds	5.47% - 10.32%	5.66	%	9.10% - 36.51%	15.63	%
Discount rates	9.59 - 12.59	10.36		8.89 - 10.39	9.32

__________________________

(1)The weighted average was calculated with reference to the principal balance of the underlying mortgages.

In recent years, there have been significant market-driven fluctuations in the assumptions listed above. Loans with higher average coupon rates have a greater likelihood of prepayment during comparatively low interest rate environments, while loans with lower average coupon rates have a lower likelihood of prepayment. The increase in rates since the year ended December 31, 2021, has caused a decrease in our weighted average prepayment speed and an increase in our discount rate assumptions used in the MSR valuation. These fluctuations can be rapid and may continue to be significant. Therefore, estimating these assumptions within ranges that market participants would use in determining the fair value of MSRs requires significant management judgment. Based upon broker estimate, the Company recorded a $2.0 million impairment on the held for sale GNMA MSR portfolio during the quarter ended September 30, 2022.

Derivatives

Fair values for interest rate swap agreements are based upon the amounts that would be required to settle the contracts. Fair values for derivative loan commitments and forward loan sale commitments are based on the fair values of the underlying mortgage loans and the probability of such commitments being exercised. Significant management judgment and estimation is required in determining these fair value measurements.

Fair Values of Assets Recorded on a Recurring Basis for which the Fair Value Option has been Elected

Certain assets are measured at fair value on a recurring basis due to the Company's election to adopt fair value accounting treatment for those assets. This election allows for a more effective offset of the changes in fair values of the assets and the derivative instruments used to economically hedge them without the burden of complying with the requirements for hedge accounting under ASC Topic 815, Derivatives and Hedging. For assets for which the fair value has been elected, the earned current contractual interest payment is recognized in interest income, loan origination costs and fees on fair value option loans are recognized in earnings as incurred and not deferred. At September 30, 2022, and December 31, 2021, there were no gains or losses recorded attributable to changes in instrument-specific credit risk. The following tables summarize the difference between the fair value and the unpaid principal balance for financial instruments for which the fair value option has been elected:

____________________________

(1)The fair value option impact on noninterest income is offset by the derivative gain/loss recognized in noninterest income. Please see Note 8 - Mortgage Banking for more detail.

The following methodologies were used to measure the fair value of financial assets valued on a recurring basis for which the fair value option was elected:

Securities at Fair Value through Income

Securities carried at fair value through income are valued using a discounted cash flow with a credit spread applied to each instrument based on the creditworthiness of each issuer. Credit spreads ranged from 83 to 227 basis points at both September 30, 2022, and December 31, 2021. The Company believes the fair value approximates an exit price.

Loans Held for Sale

Fair values for loans held for sale are established using anticipated sale prices for loans allocated to a sale commitment, and those unallocated to a commitment are valued based on the interest rate and term for similar loans allocated. The Company believes the fair value approximates an exit price.

Fair Value of Assets Recorded on a Nonrecurring Basis

Equity Securities without Readily Determinable Fair Values

Equity securities without readily determinable fair values totaled $53.9 million and $45.2 million at September 30, 2022, and December 31, 2021, respectively, and are shown on the face of the consolidated balance sheets. The majority of the Company's equity investments qualify for the practical expedient allowed for equity securities without a readily determinable fair value, such that the Company has elected to carry these securities at cost adjusted for any observable transactions during the period, less any impairment. To date, no impairment has been recorded on the Company's investments in equity securities that do not have readily determinable fair values.

Government National Mortgage Association Repurchase Asset

The Company recorded $26.2 million and $43.4 million, respectively, at September 30, 2022, and December 31, 2021, for Government National Mortgage Association ("GNMA") repurchase assets included in loans held for sale on the consolidated balance sheets. The assets are valued at the lower of cost or market and, where market is lower than cost, valued using anticipated sale prices for loans allocated to a sale commitment, and those unallocated to a commitment are valued based on the interest rate and term for similar loans allocated. The Company believes the fair value approximates an exit price. Please see Note 8 - Mortgage Banking for more information on the GNMA repurchase asset.

Individually Evaluated Loans with Credit Losses

Loans for which it is probable that the Company will not collect all principal and interest due according to contractual terms are measured to determine if any credit loss exists. Allowable methods for determining the amount of credit loss include estimating the fair value using the fair value of the collateral for collateral-dependent loans and a discounted cash flow methodology for other evaluated loans that are not collateral dependent. If the loan is identified as collateral-dependent, the fair value method of measuring the amount of credit loss is utilized. Evaluating the fair value of the collateral for collateral-dependent loans requires obtaining a current independent appraisal of the collateral and applying a discount factor to the value. If the loan is not collateral-dependent, the discounted cash flow method is utilized, which involves assumptions and judgments as to credit risk, prepayment risk, liquidity risk, default rates, loss severity, payment speeds, collateral values and discount rate. Loans that have experienced a credit loss with specific allocated losses are within Level 3 of the fair value hierarchy when the credit loss is determined using the fair value method. The fair value of loans that have experienced a credit loss with specific allocated losses was approximately $25.9 million and $4.8 million at September 30, 2022, and December 31, 2021, respectively.

Non-Financial Assets

Foreclosed assets held for sale are the only non-financial assets valued on a non-recurring basis that are initially recorded by the Company at fair value, less estimated costs to sell. At foreclosure, if the fair value, less estimated costs to sell, of the real estate acquired is less than the Company's recorded investment in the related loan, a write-down is recognized through a charge to the allowance for loan credit losses. Additionally, valuations are periodically performed by management, and any subsequent reduction in value is recognized by a charge to income. The carrying value and fair value of foreclosed assets held for sale was estimated using Level 3 inputs based on observable market data and was $1.8 million at September 30, 2022, and December 31, 2021. At September 30, 2022, the Company had $10,000 in principal amount of residential mortgage loans in the process of foreclosure.

Fair Values of Financial Instruments Not Recorded at Fair Value

Loans

The estimated fair value approximates carrying value for variable-rate loans that reprice frequently and with no significant change in credit risk. The fair value of fixed rate loans and variable-rate loans, which reprice on an infrequent basis, is estimated by discounting future cash flows using exit level pricing, which combines the current interest rates at which similar loans with similar terms would be made to borrowers of similar credit quality and an estimated additional rate to reflect a liquidity premium. An overall valuation adjustment is made for specific credit risks as well as general portfolio credit risk.

Deposits

The estimated fair value approximates carrying value for demand deposits. The fair value of fixed rate deposit liabilities with defined maturities is estimated by discounting future cash flows using the interest rates currently available for funding from the FHLB. The estimated fair value of deposits does not take into account the value of our long-term relationships with depositors, commonly known as core deposit intangibles, which are separate intangible assets, and not considered financial instruments. Nonetheless, the Company would likely realize a core deposit premium if the deposit portfolio were sold in the principal market for such deposits.

Borrowed Funds

The estimated fair value approximates carrying value for short-term borrowings. The fair value of long-term fixed rate and fixed-to-floating-rate borrowings is estimated using quoted market prices, if available, or by discounting future cash flows using current interest rates for similar financial instruments. The estimated fair value approximates carrying value for variable-rate junior subordinated debentures that reprice quarterly.

The carrying value and estimated fair values of financial instruments not recorded at fair value are as follows:



(Dollars in thousands)	September 30, 2022				December 31, 2021
Financial assets: Level 1 inputs:	Carrying Value		Estimated Fair Value		Carrying Value		Estimated Fair Value

______________________________ (1)Based upon broker estimate, the Company recorded a $2.0 million impairment on the held for sale GNMA MSR portfolio during the quarter ended September 30, 2022.

The Company receives annual servicing fee income approximating 0.28% of the outstanding balance of the underlying loans. In connection with the Company's activities as a servicer of mortgage loans, the investors and the securitization trusts have no recourse to the Company's assets for failure of debtors to pay when due.

The Company is potentially subject to losses in its loan servicing portfolio due to loan foreclosures. The Company has obligations to either repurchase the outstanding principal balance of a loan or make the purchaser whole for the economic benefits of a loan if it is determined that the loan sold violated representations or warranties made by the Company and/or the borrower at the time of the sale, which the Company refers to as mortgage loan servicing putback expenses. Such representations and warranties typically include those made regarding loans that had missing or insufficient file documentation and/or loans obtained through fraud by borrowers or other third parties. Putback claims may be made until the loan is paid in full. When a putback claim is received, the Company evaluates the claim and takes appropriate actions based on the nature of the claim. The Company is required by the Federal National Mortgage Association and the Federal Home Loan Mortgage Corporation to provide a response to putback claims within 60 of the date of receipt.

At September 30, 2022, and December 31, 2021, the reserve for mortgage loan servicing putback expenses totaled $260,000 and $379,000, respectively. There is inherent uncertainty in reasonably estimating the requirement for reserves against future mortgage loan servicing putback expenses. Future putback expenses depend on many subjective factors, including the review procedures of the purchasers and the potential refinance activity on loans sold with servicing released and the subsequent consequences under the representations and warranties.

GNMA optional repurchase programs allow financial institutions to buy back individual delinquent mortgage loans that meet certain criteria from the securitized loan pool for which the institution provides servicing. At the servicer's option, and without GNMA's prior authorization, the servicer may repurchase a delinquent loan for an amount equal to 100% of the remaining principal balance of the loan. This buy-back option is considered a conditional option until the delinquency criteria are met, at which time the option becomes unconditional. When a financial institution is deemed to have regained effective control over these loans under the unconditional buy-back option, the loans can no longer be reported as sold and must be included in the balance sheet as mortgage loans held for sale, regardless of whether the institution intends to exercise the buy-back option. These loans totaled $26.2 million and $43.4 million at September 30, 2022, and December 31, 2021, respectively, and were recorded as mortgage loans held for sale at the lower of cost or fair value with a corresponding liability in FHLB advances and other borrowings on the Company's consolidated balance sheets.

In conjunction with the BTH merger, the Company assumed certain repurchase agreements with former BTH depositors that included the sale and repurchase of BTH investment securities of at least equal to the daily balance of the BTH depositor's account, subject to maximum limitations. These agreements totaled $9.1 million at September 30, 2022.

The Company's repurchase agreements with depositors include the sale and repurchase of investment securities and mature on a daily basis or were securitized with a letter of credit from the Federal Home Loan Bank. The total repurchase agreements with depositors carried a daily average interest rate of 0.14% for the nine months ended September 30, 2022, and 0.08% for the year ended December 31, 2021.

As detailed in the table below and included in subordinated indebtedness, net in the table above, on August 1, 2022, the Company assumed $37.6 million of subordinated promissory notes ("Notes") from BTH.

The Notes are intended to qualify for Tier 2 capital treatment and are substantively identical in terms and conditions, including priority, except for the maturity dates and interest rates payable on the Company's legacy subordinated notes. Interest is payable on the Notes quarterly, and the principal amount of each Note is payable at maturity. After the five-year anniversary of issuance, the Company can redeem the Notes in part or in full at the Company’s discretion and, if applicable, subject to receipt of any required regulatory approvals. In addition, the Notes can be redeemed at any time without penalty, upon not less than ten days’ notice, in the event that (i) the Notes no longer qualify as Tier 2 capital as a result of any amendment or change in interpretation or application of laws or regulation that becomes effective after the date of issuance of the Notes, or (ii) a tax event, or (iii) investment company act event, as defined in the Notes. The Notes are unsecured and rank senior to the Company’s common stock, any preferred stock that may be issued, and the BTH TruPS (defined above).

On August 1, 2022, the Company assumed BTH's obligations with respect to $7.2 million in aggregate principal amount of junior subordinated debentures issued to a statutory trust of BTH ("BTH TruPS"). The BTH TruPS and the Company's two other wholly-owned, unconsolidated subsidiary grantor trusts were established for the purpose of issuing trust preferred securities. The trust preferred securities accrue and pay distributions periodically at specified annual rates as provided in each trust agreement. The trusts used the net proceeds from each of the offerings to purchase a like amount of junior subordinated debentures (the "debentures") of the Company. The debentures are the sole assets of the trusts. The Company's obligations under the debentures and related documents, taken together, constitute a full and unconditional guarantee by the Company of the obligations of the trusts. The trust preferred securities are mandatorily redeemable upon maturity of the debentures and can be currently redeemed by the Company in whole or in part at a redemption price equal to 100% of the outstanding principal amount of the debentures, plus any accrued but unpaid interest to the redemption date. The trust preferred securities qualify as Tier 1 capital of the Company for regulatory purposes, subject to certain limitations.

The following table is a summary of the terms of the current junior subordinated debentures at September 30, 2022:

Derivative Financial Instruments

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative Financial Instruments

Note 11 - Derivative Financial Instruments

Risk Management Objective of Using Derivatives

The Company enters into derivative financial instruments to manage risks related to differences in the amount, timing, and duration of the Company's known or expected cash receipts and its known or expected cash payments, as well as to manage changes in fair values of some assets which are marked at fair value through the consolidated statement of income on a recurring basis.

Cash Flow Hedges of Interest Rate Risk

The Company is a party to an interest rate swap agreement under which the Company receives interest at a variable rate and pays at a fixed rate. The derivative instrument represented by this swap agreement is designated as a cash flow hedge of the Company's forecasted variable cash flows under a variable-rate term borrowing agreement. During the term of the swap agreement, the effective portion of changes in the fair value of the derivative instrument are recorded in accumulated other comprehensive income (loss) and subsequently reclassified into earnings in the periods that the hedged forecasted variable-rate interest payments affected earnings. There was no ineffective portion of the change in fair value of the derivative recognized directly in earnings. The entire swap fair value will be reclassified into earnings before the expiration date of the swap agreement.

Derivatives Not Designated as Hedges

Customer interest rate derivative program

The Company offers certain derivatives products, primarily interest rate swaps, directly to qualified commercial banking customers to facilitate their risk management strategies. In some instances, the Company acts only as an intermediary, simultaneously entering into offsetting agreements with unrelated financial institutions, thereby mitigating its net risk exposure resulting from such transactions without significantly impacting its results of operations. Because the interest rate derivatives associated with this program do not meet hedge accounting requirements, changes in the fair value of both the customer derivatives and any offsetting derivatives are recognized directly in earnings as a component of noninterest income.

From time to time, the Company shares in credit risk on interest rate swap arrangements, by entering into risk participation agreements with syndication partners. These are accounted for at fair value and disclosed as risk participation derivatives.

Mortgage banking derivatives

The Company enters into certain derivative agreements as part of its mortgage banking and related risk management activities. These agreements include interest rate lock commitments on prospective residential mortgage loans and forward commitments to sell these loans to investors on a mandatory delivery basis. The Company also economically hedges the value of MSRs by entering into a series of commitments to purchase mortgage-backed securities in the future.

Fair Values of Derivative Instruments on the Balance Sheet

The following tables disclose the fair value of derivative instruments in the Company's balance sheets at September 30, 2022, and December 31, 2021, as well as the effect of these derivative instruments on the Company's consolidated statements of income for the nine months ended September 30, 2022 and 2021. Derivative instruments and their related gains and losses are reported in other operating activities, net in the statement of cash flows.

____________________________

(1)Notional or contractual amounts, which represent the extent of involvement in the derivatives market, are used to determine the contractual cash flows required in accordance with the terms of the agreement. These amounts are typically not exchanged, significantly exceed amounts subject to credit or market risk and are not reflected in the consolidated balance sheets.

The weighted-average rates paid and received for interest rate swaps at September 30, 2022, were as follows:


	Weighted-Average Interest Rate

Interest rate swaps:	Paid		Received
Cash flow hedges	4.48	%	4.71	%
Non-hedging interest rate swaps - financial institution counterparties	4.26		4.72
Non-hedging interest rate swaps - customer counterparties	4.72		4.26

Gains and losses recognized on derivative instruments not designated as hedging instruments are as follows:

Amount of gain recognized in other non-interest income	210		75		652		409

____________________________

(1)Gains and losses on these instruments are largely offset by market fluctuations in mortgage servicing rights. See Note 8 - Mortgage Banking for more information on components of mortgage banking revenue.

Some interest rate swaps included in other assets were subject to a master netting arrangement with the counterparty in all periods presented and could be offset against some amounts included in interest rate swaps included in other liabilities. The Company has chosen not to net these exposures in the consolidated balance sheets, and any impact of netting these amounts would not be significant.

At September 30, 2022, and December 31, 2021, the Company had cash collateral on deposit with swap counterparties totaling $7.6 million and $16.5 million, respectively. These amounts are included in interest-bearing deposits in banks in the consolidated balance sheets and are considered restricted cash until such time as the underlying swaps are settled.

Stock and Incentive Compensation Plans

Share-Based Payment Arrangement [Abstract]

Stock and Incentive Compensation Plans

Note 12 - Stock and Incentive Compensation Plans

The Company has granted, and currently has outstanding, stock and incentive compensation awards subject to the provisions of the Company's 2012 Stock Incentive Plan (the "2012 Plan"). The 2012 Plan is designed to provide flexibility to the Company regarding its ability to motivate, attract and retain the services of key officers, employees and directors. The 2012 Plan allows the Company to make grants of incentive stock options, non-qualified stock options, stock appreciation rights, restricted stock awards ("RSA"), restricted stock units ("RSU"), dividend equivalent rights, performance stock units ("PSU") or any combination thereof. At September 30, 2022, the maximum number of shares of the Company's common stock available for issuance under the 2012 Plan was 458,242 shares.

Additionally, in April 2021, an employee stock purchase plan ("ESPP") was approved by the Company's stockholders and qualified as an ESPP under IRS guidelines. The ESPP provides for the purchase of up to an aggregate one million shares of the Company's common stock by employees pursuant to the terms of the ESPP, and the total number of shares available for issuance at September 30, 2022, was 973,911. Under the ESPP, employees of the Company, who elect to participate, have the right to purchase a limited number of shares of the Company's common stock at a 15% discount from the lower of the market value of the common stock at the beginning or the end of each one year offering period, beginning on June 1st. The ESPP benefit is treated as compensation to the employee, and the compensation expense will be recognized over the service period based on the fair value of the rights on the grant date, adjusted for forfeitures and certain modifications.

Under the ESPP, employees purchased 26,089 shares during the nine months ended September 30, 2022, and no shares of common stock were issued pursuant to the ESPP during the nine months ended September 30, 2021.

In February 2022, the Compensation Committee ("Committee") approved and the Company granted PSUs to select officers and employees under the 2012 Plan. Each PSU represents a right for the participant to receive shares of Company common stock or cash equal to the fair market value of such stock, as determined by the Committee. The number of PSUs to which the participant may be entitled will vary from 0% to 150% of the target number of PSUs, based on the Company’s achievement of specified performance criteria during the performance period compared to performance benchmarks adopted by the Committee and, further, the participant's continuous service with the Company through the third anniversary of the date of the grant. The performance period is the three-year period commencing on January 1, 2022, and ending on December 31, 2024, ("Performance Period").

Share-based compensation cost charged to income for the three and nine months ended September 30, 2022 and 2021, is presented below. There was no stock option expense for any of the periods shown.

Restricted Stock and Performance Stock Grants

The Company's RSAs and RSUs are time-vested awards and are granted to the Company's Board of Directors, executives and senior management team. The service period in which time-vested awards are earned ranges from one to five years. Time-vested awards are valued utilizing the fair value of the Company's stock at the grant date. These awards are recognized on the straight-line method over the requisite service period, with forfeitures recognized as they occur.

The Company's PSU awards are three-year cliff-vested awards, with each unit divided into two categories ("ROAA Unit Group" and "ROAE Unit Group"), composed of an equivalent number of initial PSUs which do not reflect potential increases or decreases resulting from the final performance results determined at the end of the three-year period. The ROAA Unit Group is based upon the Company's Performance Period Return on Average Assets performance, and the ROAE Unit Group is based upon the Company's Performance Period Return on Average Equity performance. The PSUs are initially valued utilizing the fair value of the Company's stock at the grant date, assuming 100% of the target number of units are achieved. Subsequent valuation of the PSUs is determined using the ratio of the actual Company's Performance Period ROAA or ROAE to the Company's targeted Performance Period ROAA or ROAE, applied to the PSUs awarded times the Company's period end stock price. Forfeitures are recognized as they occur.

The following table summarizes the Company's award activity:


	Nine Months Ended September 30,

At September 30, 2022, there was $778,000, $5.2 million and $1.1 million of total unrecognized compensation cost related to nonvested RSA shares, RSU shares and PSU shares under the 2012 Plan, respectively. Those costs are expected to be recognized over a weighted-average period of 0.9, 2.7 and 2.4 years for RSA, RSU and PSU shares, respectively.

Stock Option Grants

The Company has previously issued common stock options to select officers and employees primarily through individual agreements. The exercise price of each option varies by agreement and is based on the fair value of the stock at the date of the grant. No outstanding stock option has a term that exceeds twenty years, and all of the outstanding options are fully vested. The Company recognized compensation cost for stock option grants over the required service period based upon the grant date fair value, which is established using a Black-Scholes valuation model. The Black-Scholes valuation model uses assumptions of risk-free interest rate, expected term of stock options, expected stock price volatility and expected dividends. Forfeitures are recognized as they occur.

In conjunction with the BTH merger, the Company assumed the BTH 2012 Equity Incentive Plan and converted all outstanding options to purchase BTH common stock into options to purchase an aggregate of 611,676 shares of the Company's common stock. Under the terms of applicable change in control provisions within the BTH 2012 Equity Incentive Plan and BTH Notice Of Stock Option Award, all BTH stock options fully vested immediately prior to the closing of the merger that occurred on August 1, 2022. BTH converted options have no expiration dates past August 16, 2031, and no further grants will be made under the BTH 2012 Equity Incentive Plan.

The table below summarizes the status of the Company's stock options and changes during the nine months ended September 30, 2022 and 2021.

Capital and Regulatory Matters

Note 14 - Capital and Regulatory Matters

The Company (on a consolidated basis) and the Banks are subject to various regulatory capital requirements administered by federal and state banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company's consolidated financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company and the Banks must meet specific capital guidelines that involve quantitative measures of assets, liabilities and certain off-balance sheet items as calculated under regulatory accounting practices. The capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings and other factors.

As of September 30, 2022, and December 31, 2021, BTH Bank was a qualifying community banking organization as defined by the federal banking agencies and elected to measure capital adequacy under the community bank leverage ratio ("CBLR") framework. The CBLR removes the requirement for qualifying banking organizations to calculate and report risk-based capital and only requires a Tier 1 to average assets (leverage) ratio. Qualifying banking organizations that elect to use the community bank leverage ratio framework and that maintain a leverage ratio of greater than required minimums will be considered to have satisfied the generally applicable risk based and leverage capital requirements in the agencies’ capital rules (generally applicable rule) and, if applicable, will be considered to have met the well capitalized ratio requirements for purposes of section 38 of the Federal Deposit Insurance Act. Under the interim final rules, the community bank leverage ratio minimum requirement is 9% for calendar year 2022 and beyond. The interim rule allows for a two-quarter grace period to correct a ratio that falls below the required amount, provided that BTH Bank maintains a leverage ratio of no less than 8%. At September 30, 2022, and December 31, 2021, BTH Bank met the CBLR minimum Tier 1 to average assets ratio. Effective October 7, 2022, BTH Bank was merged into Origin Bank and will cease to exist as a stand-alone entity.

The Company is subject to the Basel III regulatory capital framework ("Basel III Capital Rules"), which includes a 2.5% capital conservation buffer. The capital conservation buffer is designed to absorb losses during periods of economic stress and requires increased capital levels for the purpose of capital distributions and other payments. Failure to meet the full amount of the buffer will result in restrictions on the Company's ability to make capital distributions, which include dividend payments, stock repurchases and to pay discretionary bonuses to executive officers.

Quantitative measures established by regulation to ensure capital adequacy require the Company and Origin to maintain minimum amounts and ratios (set forth in the table below) of total, common equity Tier 1 capital, Tier 1 capital, Tier 1 capital, and total capital (as defined in the regulations) to risk-weighted assets (as defined), and of Tier 1 capital (as defined) to average total consolidated assets (as defined). Management believes, at September 30, 2022, and December 31, 2021, that the Company and the Origin met all capital adequacy requirements to which they are subject, including the capital buffer requirement.

At September 30, 2022, and December 31, 2021, Origin's capital ratios exceeded those levels necessary to be categorized as "well capitalized" under the regulatory framework for prompt corrective action. To be categorized as "well capitalized," Origin must maintain minimum total risk-based, common equity Tier 1 capital, Tier 1 risk-based and Tier 1 leverage ratios as set forth in the table below. A final rule adopted by the federal banking agencies in February 2019 provides banking organizations with the option to phase in, over a three-year period, the adverse day-one regulatory capital effects of the adoption of CECL. In addition, on March 27, 2020, the federal banking agencies issued an interim final rule that gives banking organizations that were required to implement CECL before the end of 2020 the option to delay for two years CECL’s adverse effects on regulatory capital. Origin elected to adopt CECL in the first quarter of 2020 and exercised the option to delay the estimated impact of the adoption of CECL on the Company's regulatory capital for two years (from January 2020 through December 31, 2021). The two-year delay is followed by a three-year transition period of CECL's initial impact on our regulatory capital (from January 1, 2022, through December 31, 2024). The amount representing the CECL impact to the Company's regulatory capital that will be ratably transitioning back into regulatory capital over the transition period is $5.7 million and $7.6 million at September 30, 2022, and December 31, 2021, respectively.

The actual capital amounts and ratios of the Company and Origin at September 30, 2022, and December 31, 2021, are presented in the following table:

In the ordinary course of business, the Company depends on dividends from the Banks to provide funds for the payment of dividends to stockholders and to provide for other cash requirements. Banking regulations may limit the amount of dividends that may be paid. Approval by regulatory authorities is required if the effect of dividends declared would cause the regulatory capital of the Banks to fall below specified minimum levels. Approval is also required if dividends declared and paid exceed the Bank's year-to-date net income combined with the retained net income for the preceding year, which was $137.4 million at September 30, 2022.

Stock Repurchases

In July 2019, the Company's board of directors authorized a stock repurchase program pursuant to which the Company was authorized purchase up to $40 million of its outstanding common stock. The stock repurchase program was approved for a period of three years and expired in June 2022, having repurchased a total of $28.0 million of outstanding common stock. In July 2022, the Board of Directors of the Company authorized a stock repurchase program pursuant to which the Company may, from time to time, purchase up to $50 million of its outstanding common stock. The shares may be repurchased in the open market or in privately negotiated transactions from time to time, depending upon market conditions and other factors, and in accordance with applicable regulations of the Securities and Exchange Commission. The stock repurchase program is intended to expire in three years but may be terminated or amended by the Board of Directors at any time. The stock repurchase program does not obligate the Company to purchase any shares at any time.

Commitments and Contingencies

Note 15 - Commitments and Contingencies

Credit-Related Commitments

In the ordinary course of business, the Company enters into financial instruments, such as commitments to extend credit and letters of credit, to meet the financing needs of its customers. Such instruments are not reflected in the accompanying consolidated financial statements until they are funded, although they expose the Company to varying degrees of credit risk and interest rate risk in much the same way as funded loans.

Commitments to extend credit include revolving commercial credit lines, non-revolving loan commitments issued mainly to finance the merger and development or construction of real property or equipment, and credit card and personal credit lines. The availability of funds under commercial credit lines and loan commitments generally depends on whether the borrower continues to meet credit standards established in the underlying contract and has not violated other contractual conditions. Loan commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee by the borrower. Credit card and personal credit lines are generally subject to cancellation if the borrower's credit quality deteriorates. A number of commercial and personal credit lines are used only partially or, in some cases, not at all before they expire, and the total commitment amounts do not necessarily represent future cash requirements of the Company.

A substantial majority of the letters of credit are standby agreements that obligate the Company to fulfill a customer's financial commitments to a third party if the customer is unable to perform. The Company issues standby letters of credit primarily to provide credit enhancement to its customers' other commercial or public financing arrangements and to help them demonstrate financial capacity to vendors of essential goods and services.

The contract amounts of these instruments reflect the Company's exposure to credit risk. The Company undertakes the same credit evaluation in making loan commitments and assuming conditional obligations as it does for on-balance sheet instruments and may require collateral or other credit support.

The table below presents the Company's commitments to extend credit by commitment expiration date for the dates indicated:


(Dollars in thousands) September 30, 2022
	Less than One Year		One-Three Years		Three-Five Years		Greater than Five Years		Total

____________________________

(1)Includes $567.9 million and $513.0 million of unconditionally cancellable commitments at September 30, 2022 and December 31, 2021, respectively.

At September 30, 2022, the Company held 29 unfunded letters of credit from the FHLB totaling $262.3 million, with expiration dates ranging from October 18, 2022, to September 22, 2027. At December 31, 2021, the Company held 43 unfunded letters of credit from the FHLB totaling $599.3 million, with expiration dates ranging from January 20, 2022, to March 22, 2023.

The Company has a total contingent liability of $3.1 million as of September 30, 2022, for retention bonuses and guaranteed minimum incentives. The contingent liability consists of retention bonuses totaling $1.0 million for former BTH employees, with $523,000, or 50%, due at December 31, 2023, and the remaining $523,000, or 50%, due at December 31, 2024. Additionally, the Company will pay $2.0 million, in total, in guaranteed minimum incentives to certain employees with approximately 42% due on or about December 31, 2023, and 29% each due on or about December 31, 2024 and 2025, respectively. In all cases, continued employment through the payout date is required in order to receive the compensation.

In conjunction with the December 31, 2021, acquisitions of the Lincoln Agency, LLC. and Pulley-White Insurance Agency, Inc., the Company has a total fair value contingent liability of $1.4 million as of December 31, 2021. The amount is payable if Davison Insurance Agency, LLC, the acquirer and surviving wholly-owned subsidiary of the Company, meets certain revenue growth objectives over three years. The fair value and probability of payout of this liability is reassessed annually at the fiscal year end of the Company.

Management establishes an asset-specific allowance for certain lending-related commitments and computes a formula-based allowance for performing consumer and commercial lending-related commitments. These are computed using a methodology similar to that used for the commercial loan portfolio, modified for expected maturities and probabilities of drawdown. The reserve for lending-related commitments was $5.2 million and $2.3 million at September 30, 2022, and December 31, 2021, respectively, and is included in accrued expenses and other liabilities in the accompanying consolidated balance sheets.

Loss Contingencies

From time to time, the Company is also party to various legal actions arising in the ordinary course of business. At this time, management does not expect that loss contingencies, if any, arising from any such proceedings, either individually or in the aggregate, would have a material adverse effect on the consolidated financial position or liquidity of the Company.

Significant Accounting Policies (Policies)	Sep. 30, 2022
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation. The consolidated financial statements in this quarterly report on Form 10-Q include the accounts of the Company and all other entities in which Origin Bancorp, Inc. has a controlling financial interest, including the Banks and Davison Insurance Agency, LLC, doing business as Lincoln Agency, LLC (the "Lincoln Agency"), Lincoln Agency Transportation Insurance, Pulley-White Insurance Agency (the "Pulley-White"), Reeves, Coon and Funderburg, Simoneaux & Wallace Agency and Thomas & Farr Agency. All significant intercompany balances and transactions have been eliminated in consolidation. The Company's accounting and financial reporting policies conform, in all material respects, to generally accepted accounting principles in the United States ("U.S. GAAP") and to general practices within the financial services industry. The Company has evaluated subsequent events for potential recognition and/or disclosure through the date these consolidated financial statements were issued. The consolidated financial statements in this quarterly report on Form 10-Q have not been audited by an independent registered public accounting firm, excluding the figures as of December 31, 2021, but in the opinion of management, reflect all adjustments (which are of a normal recurring nature) necessary for a fair presentation of the Company's financial position and results of operations for the periods presented. These consolidated financial statements of the Company have been prepared in accordance with U.S. GAAP and with the rules and regulations of the Securities and Exchange Commission (the "SEC") for interim financial reporting. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. These consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto for the year ended December 31, 2021, included in the Company's annual report on Form 10-K ("2021 Form 10-K") filed with the SEC. Operating results for the interim periods disclosed herein are not necessarily indicative of results that may be expected for a full year. 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 (loss).
Use of Estimates	Use of Estimates. The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions based on available information that affect the amounts reported in the financial statements and disclosures provided, including the accompanying notes, and actual results could differ. Material estimates, that are particularly susceptible to change, include the allowance for credit losses for loans, off-balance sheet commitments and available for sale securities; fair value measurements of assets and liabilities; and income taxes. Estimates and assumptions are reviewed periodically, and the effects of revisions are reflected in the Company's consolidated financial statements in the period they are deemed necessary. While management uses its best judgment, actual results could differ from those estimates.
Acquisition Accounting and Acquired Loans	Acquisition Accounting and Acquired Loans. The Company accounts for its mergers/acquisitions under Financial Accounting Standards Board ("FASB") Accounting Standards Codification (ASC) Topic 805, Business Combinations, which requires the use of the acquisition method of accounting. All identifiable assets acquired, including loans, are recorded at fair value. In accordance with ASC 326, the Company records a discount or premium and also an allowance for credit losses on acquired loans. All purchased loans are recorded at fair value in accordance with the fair value methodology prescribed in FASB ASC Topic 820, Fair Value Measurements. The fair value estimates associated with the loans include estimates related to expected prepayments and the amount and timing of undiscounted expected principal, interest and other cash flows. Purchased loans that have experienced more than insignificant credit deterioration since origination are purchased credit deteriorated (“PCD”) loans. The Company evaluates acquired loans for deterioration in credit quality based on any of, but not limited to, the following: (1) non-accrual status; (2) troubled debt restructured designation; (3) risk ratings of special mention, substandard or doubtful; (4) watchlist credits; and (5) delinquency status, including loans that are current on merger/acquisition date, but had been previously delinquent two times 60 days. An allowance for credit losses is determined using the same methodology as other individually evaluated loans. The Non-PCD model utilizes data from the Banks in order to determine the probability of default and loss given default to be used in the calculation. The initial allowance for credit losses, determined on a collective basis, is allocated to individual loans. The sum of the loan’s purchase price and allowance for credit losses becomes its initial amortized cost basis. The difference between the initial amortized cost basis and the par value of the loan is a non-credit discount or premium, which is amortized or accreted into interest income over the life of the loan. Subsequent changes to the allowance for credit losses are recorded through the provision for credit losses.
Effect of Recently Adopted Accounting Standards and Effect of Newly Issued But Not Yet Effective Accounting Standards	Effect of Recently Adopted Accounting Standards Accounting Standards Update ("ASU") No. 2021-06, Presentation of Financial Statements (Topic 205), Financial Services —Depository and Lending (Topic 942), and Financial Services — Investment Companies (Topic 946) —Amendments to SEC Paragraphs Pursuant to SEC Final Rule Releases No. 33-10786, Amendments to Financial Disclosures about Acquired and Disposed Businesses, and No. 33-10835, Update of Statistical Disclosures for Bank and Savings and Loan Registrants amends the ASC in order to agree the Codification to the new SEC releases 33-10786 and 33-10835 (the "Releases"). The Releases clearly define whether an acquired or disposed business subsidiary is significant; update, expand and eliminate certain disclosures; eliminate overlap with certain SEC and U.S. GAAP rules; and add a new subpart of Regulation S-K. The ASU is effective upon issuance; however, the SEC release on which the ASU is based is effective for registrants with the first fiscal year ending after December 15, 2021, while Guide 3 will be rescinded effective January 1, 2023. Implementation of this ASU did not materially impact the Company's financial statement disclosures. Effect of Newly Issued But Not Yet Effective Accounting Standards ASU No. 2021-08, Business Combinations (Topic 805) — Accounting for Contract Assets and Contract Liabilities from Contracts with Customers. The amendments in this Update affect accounting for acquired revenue contracts with customers in a business combination by addressing diversity in practice and inconsistency related to recognition of an acquired contract liability and payment terms and their effect on subsequent revenue recognized by the acquirer. The ASU is effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. Implementation of this ASU is not expected to materially impact the Company's financial statements or disclosures. ASU No. 2022-01, Derivatives and Hedging (Topic 815) — Fair Value Hedging - Portfolio Layer Method. The amendments in this Update clarify the accounting for and promote consistency in the reporting of hedge basis adjustments applicable to both a single hedged layer and multiple hedged layers. Additionally, this Update allows entities to elect to apply the portfolio layer method of hedge accounting in accordance with Topic 815. The ASU is effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. Implementation of this ASU is not expected to materially impact the Company's financial statements or disclosures. ASU No. 2022-02, Financial Instruments - Credit Losses (Topic 326) — Troubled Debt Restructurings and Vintage Disclosures. The amendments in this Update eliminate the accounting guidance for TDRs by creditors in Subtopic 310-40, Receivables—Troubled Debt Restructurings by Creditors, while enhancing disclosure requirements for certain loan refinancings and restructurings by creditors when a borrower is experiencing financial difficulty. Specifically, rather than applying the recognition and measurement guidance for TDRs, an entity must apply the loan refinancing and restructuring guidance in paragraphs 310-20-35-9 through 35-11 to determine whether a modification results in a new loan or a continuation of an existing loan. For public business entities, the amendments in this Update require that an entity disclose current-period gross write-offs by year of origination for financing receivables and net investments in leases within the scope of Subtopic 326-20, Financial Instruments—Credit Losses—Measured at Amortized Cost. The ASU is effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. Implementation of this ASU is not expected to materially impact the Company's financial statements or disclosures.
Loans , Nonaccrual Status	All interest accrued but not received for loans placed on nonaccrual status is reversed against interest income. Subsequent receipts on nonaccrual loans are recorded as a reduction of principal, and interest income is recorded only after principal recovery is reasonably assured.
Loans Held For Sale	The Company elects the fair value option for recording residential mortgage loans held for sale in accordance with U.S. GAAP.
Fair Value of Financial Instruments	Fair value is the exchange price that is expected to be received for an asset or paid to transfer a liability (exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Certain assets and liabilities are recorded in the Company's consolidated financial statements at fair value. Some are recorded on a recurring basis and some on a non-recurring basis. The Company utilizes fair value measurement to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. The determination of fair values of financial instruments often requires the use of estimates. In cases where quoted market values in an active market are not available, the Company utilizes valuation techniques that are consistent with the market approach, the income approach and/or the cost approach to estimate the fair values of its financial instruments. Such valuation techniques are consistently applied. A hierarchy for fair value has been established, which categorizes the valuation techniques into three levels used to measure fair value. The three levels are as follows: Level 1 - Fair value is based on unadjusted quoted prices in active markets for identical assets or liabilities. Level 2 - Fair value is based on significant other observable inputs that are generally determined based on a single price for each financial instrument provided to the Company by an unrelated third-party pricing service and is based on one or more of the following: •Quoted prices for similar, but not identical, assets or liabilities in active markets; •Quoted prices for identical or similar assets or liabilities in markets that are not active; •Inputs other than quoted prices that are observable, such as interest rate and yield curves, volatilities, prepayment speeds, loss severities, credit risks and default rates; and •Other inputs derived from or corroborated by observable market inputs. Level 3 - Prices or valuation techniques that require inputs that are both significant and unobservable in the market. These instruments are valued using the best information available, some of which is internally developed, and reflects the Company's own assumptions about the risk premiums that market participants would generally require and the assumptions they would use. These estimates can be inherently uncertain. Securities Available for Sale Securities classified as available for sale are reported at fair value utilizing Level 1, Level 2 or Level 3 inputs. For Level 1 securities, the Company obtains the fair value measurements for those identical assets from an independent pricing service. For Level 2 securities, the Company obtains fair value measurements from an independent pricing service. The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, the U.S. Treasury yield curve, live trading levels, market consensus prepayment speeds, credit information and the security's terms and conditions, among other things. In order to ensure the fair values are consistent with ASC 820, Fair Value Measurements and Disclosures, the Company periodically checks the fair value by comparing them to other pricing sources, such as Bloomberg LP. The third-party pricing service is subject to an annual review of internal controls in accordance with the Statement on Standards for Attestation Engagements No. 16, which was made available to the Company. In certain cases where Level 2 inputs are not available, securities are classified within Level 3 of the hierarchy. Mortgage Servicing Rights ("MSRs")The carrying amounts of the MSRs equal fair value, which are determined using a discounted cash flow valuation model. Derivatives Fair values for interest rate swap agreements are based upon the amounts that would be required to settle the contracts. Fair values for derivative loan commitments and forward loan sale commitments are based on the fair values of the underlying mortgage loans and the probability of such commitments being exercised. Significant management judgment and estimation is required in determining these fair value measurements. Fair Values of Assets Recorded on a Recurring Basis for which the Fair Value Option has been Elected Certain assets are measured at fair value on a recurring basis due to the Company's election to adopt fair value accounting treatment for those assets. This election allows for a more effective offset of the changes in fair values of the assets and the derivative instruments used to economically hedge them without the burden of complying with the requirements for hedge accounting under ASC Topic 815, Derivatives and Hedging. For assets for which the fair value has been elected, the earned current contractual interest payment is recognized in interest income, loan origination costs and fees on fair value option loans are recognized in earnings as incurred and not deferred. The following methodologies were used to measure the fair value of financial assets valued on a recurring basis for which the fair value option was elected: Securities at Fair Value through Income Securities carried at fair value through income are valued using a discounted cash flow with a credit spread applied to each instrument based on the creditworthiness of each issuer. Credit spreads ranged from 83 to 227 basis points at both September 30, 2022, and December 31, 2021. The Company believes the fair value approximates an exit price. Loans Held for Sale Fair values for loans held for sale are established using anticipated sale prices for loans allocated to a sale commitment, and those unallocated to a commitment are valued based on the interest rate and term for similar loans allocated. The Company believes the fair value approximates an exit price. Fair Value of Assets Recorded on a Nonrecurring Basis Equity Securities without Readily Determinable Fair Values Equity securities without readily determinable fair values totaled $53.9 million and $45.2 million at September 30, 2022, and December 31, 2021, respectively, and are shown on the face of the consolidated balance sheets. The majority of the Company's equity investments qualify for the practical expedient allowed for equity securities without a readily determinable fair value, such that the Company has elected to carry these securities at cost adjusted for any observable transactions during the period, less any impairment. To date, no impairment has been recorded on the Company's investments in equity securities that do not have readily determinable fair values. Government National Mortgage Association Repurchase Asset The Company recorded $26.2 million and $43.4 million, respectively, at September 30, 2022, and December 31, 2021, for Government National Mortgage Association ("GNMA") repurchase assets included in loans held for sale on the consolidated balance sheets. The assets are valued at the lower of cost or market and, where market is lower than cost, valued using anticipated sale prices for loans allocated to a sale commitment, and those unallocated to a commitment are valued based on the interest rate and term for similar loans allocated. The Company believes the fair value approximates an exit price. Please see Note 8 - Mortgage Banking for more information on the GNMA repurchase asset. Individually Evaluated Loans with Credit Losses Loans for which it is probable that the Company will not collect all principal and interest due according to contractual terms are measured to determine if any credit loss exists. Allowable methods for determining the amount of credit loss include estimating the fair value using the fair value of the collateral for collateral-dependent loans and a discounted cash flow methodology for other evaluated loans that are not collateral dependent. If the loan is identified as collateral-dependent, the fair value method of measuring the amount of credit loss is utilized. Evaluating the fair value of the collateral for collateral-dependent loans requires obtaining a current independent appraisal of the collateral and applying a discount factor to the value. If the loan is not collateral-dependent, the discounted cash flow method is utilized, which involves assumptions and judgments as to credit risk, prepayment risk, liquidity risk, default rates, loss severity, payment speeds, collateral values and discount rate. Loans that have experienced a credit loss with specific allocated losses are within Level 3 of the fair value hierarchy when the credit loss is determined using the fair value method. The fair value of loans that have experienced a credit loss with specific allocated losses was approximately $25.9 million and $4.8 million at September 30, 2022, and December 31, 2021, respectively. Non-Financial Assets Foreclosed assets held for sale are the only non-financial assets valued on a non-recurring basis that are initially recorded by the Company at fair value, less estimated costs to sell. At foreclosure, if the fair value, less estimated costs to sell, of the real estate acquired is less than the Company's recorded investment in the related loan, a write-down is recognized through a charge to the allowance for loan credit losses. Additionally, valuations are periodically performed by management, and any subsequent reduction in value is recognized by a charge to income. The carrying value and fair value of foreclosed assets held for sale was estimated using Level 3 inputs based on observable market data
Derivative Instruments and Hedging Activities	Risk Management Objective of Using Derivatives The Company enters into derivative financial instruments to manage risks related to differences in the amount, timing, and duration of the Company's known or expected cash receipts and its known or expected cash payments, as well as to manage changes in fair values of some assets which are marked at fair value through the consolidated statement of income on a recurring basis. Cash Flow Hedges of Interest Rate Risk The Company is a party to an interest rate swap agreement under which the Company receives interest at a variable rate and pays at a fixed rate. The derivative instrument represented by this swap agreement is designated as a cash flow hedge of the Company's forecasted variable cash flows under a variable-rate term borrowing agreement. During the term of the swap agreement, the effective portion of changes in the fair value of the derivative instrument are recorded in accumulated other comprehensive income (loss) and subsequently reclassified into earnings in the periods that the hedged forecasted variable-rate interest payments affected earnings. There was no ineffective portion of the change in fair value of the derivative recognized directly in earnings. The entire swap fair value will be reclassified into earnings before the expiration date of the swap agreement. Derivatives Not Designated as Hedges Customer interest rate derivative program The Company offers certain derivatives products, primarily interest rate swaps, directly to qualified commercial banking customers to facilitate their risk management strategies. In some instances, the Company acts only as an intermediary, simultaneously entering into offsetting agreements with unrelated financial institutions, thereby mitigating its net risk exposure resulting from such transactions without significantly impacting its results of operations. Because the interest rate derivatives associated with this program do not meet hedge accounting requirements, changes in the fair value of both the customer derivatives and any offsetting derivatives are recognized directly in earnings as a component of noninterest income. From time to time, the Company shares in credit risk on interest rate swap arrangements, by entering into risk participation agreements with syndication partners. These are accounted for at fair value and disclosed as risk participation derivatives. Mortgage banking derivatives The Company enters into certain derivative agreements as part of its mortgage banking and related risk management activities. These agreements include interest rate lock commitments on prospective residential mortgage loans and forward commitments to sell these loans to investors on a mandatory delivery basis. The Company also economically hedges the value of MSRs by entering into a series of commitments to purchase mortgage-backed securities in the future. Some interest rate swaps included in other assets were subject to a master netting arrangement with the counterparty in all periods presented and could be offset against some amounts included in interest rate swaps included in other liabilities. The Company has chosen not to net these exposures in the consolidated balance sheets, and any impact of netting these amounts would not be significant.

- Definition

Total of all stockholders' equity (deficit) items, net of receivables from officers, directors, owners, and affiliates of the entity which are attributable to the parent. The amount of the economic entity's stockholders' equity attributable to the parent excludes the amount of stockholders' equity which is allocable to that ownership interest in subsidiary equity which is not attributable to the parent (noncontrolling interest, minority interest). This excludes temporary equity and is sometimes called permanent equity.
