SEACOAST BANKING CORP OF FLORIDA

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

Note 1 –Basis of Presentation

Basis of Presentation: The accompanying unaudited consolidated financial statements of Seacoast Banking Corporation of Florida and its subsidiaries (the “Company”) have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Certain prior period amounts have been reclassified to conform to the current period presentation.

Operating results for the three and nine months ended September 30, 2024, are not necessarily indicative of the results that may be expected for the year ending December 31, 2024, or any other period. For further information, refer to the consolidated financial statements and footnotes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023.

Use of Estimates: The preparation of these consolidated financial statements requires management to make judgments in the application of certain accounting policies that involve significant estimates and assumptions. The Company has established policies and control procedures that are intended to ensure valuation methods are well-controlled and applied consistently from period to period. These estimates and assumptions, which may materially affect the reported amounts of certain assets, liabilities, revenues, and expenses, are based on information available as of the date of the financial statements, and changes in this information over time and the use of revised estimates and assumptions could materially affect amounts reported in subsequent financial statements. Specific areas, among others, requiring the application of management’s estimates include the determination of the allowance for credit losses, acquisition accounting and purchased loans, intangible assets and impairment testing, and other fair value measurements.

Issued Accounting Standards

In November 2023, the FASB issued ASU 2023-07, “Improvements to Reportable Segment Disclosures.” ASU 2023-07 requires disclosure of significant segment expenses and other segment items on an interim and annual basis. The standard is effective for fiscal years beginning after December 15, 2023 and for interim periods beginning after December 15, 2024. The Company is evaluating the impact of the changes to its existing disclosures.

In December 2023, the FASB issued ASU 2023-09, “Improvements to Income Tax Disclosures.” ASU 2023-09 requires disclosure of specific categories in the income tax rate reconciliation and requires additional information for reconciling items that meet a quantitative threshold. The standard requires an annual disclosure of income taxes paid, net of refunds received, disaggregated by federal, state and foreign taxes and to disaggregate the information by jurisdiction based on a quantitative threshold. The standard is effective for fiscal years beginning after December 15, 2024 and early adoption is permitted. The Company does not expect the adoption of the standard to have a material impact on its disclosures.

In November 2024, the FASB issued ASU 2024-03, “Expense Disaggregation Disclosures.” ASU 2024-03 requires disclosure to disaggregate prescribed expenses within relevant income statement captions. The standard is effective for fiscal years beginning after December 15, 2026 and for interim periods after December 15, 2027. Early adoption is permitted. The Company is evaluating the impact of the changes to its existing disclosures.

Note 2 –Earnings per Share

Basic earnings per common share are computed by dividing net income available to common shareholders by the weighted-average number of shares of common stock outstanding during the period. Diluted earnings per share are based on the weighted-average number of common shares outstanding during each period, plus common share equivalents, calculated for share-based awards outstanding using the treasury stock method.

For the three and nine months ended September 30, 2024, options to purchase shares of the Company’s common stock totaling 327,006 and 328,045, respectively, were anti-dilutive. For the three and nine months ended September 30, 2023,368,968 options to purchase shares of the Company’s common stock were anti-dilutive.

Note 3 –Securities

The amortized cost, gross unrealized gains and losses and fair value of securities available-for-sale (“AFS”) and held-to-maturity (“HTM”) at September 30, 2024 and December 31, 2023 are summarized as follows:

During the three months ended September 30, 2024, debt securities with a fair value of $17.6 million were sold, with gross losses of $0.3 million. There wereno sales of debt securities during the three months ended September 30, 2023. During the nine months ended September 30, 2024, debt securities with a fair value of $104.4 million were sold, with gross losses of $4.0 million. During the nine months ended September 30, 2023, debt securities with a fair value of $22.1 million obtained in the acquisition of Professional Holding Corp. (“Professional”) were sold. No gain or loss was recognized on the sale. There were $8.4 million in other sales of securities during the nine months ended September 30, 2023, with gross gains of $24 thousand and gross losses of $19 thousand. Included in “Securities gains (losses), net” are increases of $0.5 million and $0.3 million, respectively, for the three and nine months ended September 30, 2024, and decreases of $0.4 million and $0.5 million, respectively, for the three and nine months ended September 30, 2023 in the value of investments in mutual funds that invest in Community Reinvestment Act (“CRA”)-qualified debt securities.

At September 30, 2024, debt securities with a fair value of $1.5 billion were pledged primarily as collateral for public deposits and secured borrowings.

The amortized cost and fair value of securities HTM and AFS as of September 30, 2024, by contractual maturity, are shown below. Expected maturities will differ from contractual maturities because prepayments of the underlying collateral for these securities may occur, due to the right to call or repay obligations with or without call or prepayment penalties. Securities not due at a single maturity date are shown separately.

The estimated fair value of a security is determined based on market quotations when available or, if not available, by using quoted market prices for similar securities, pricing models, or discounted cash flow analyses, or using observable market data. The tables below indicate the fair value of AFS debt securities with unrealized losses for which no allowance for credit losses has been recorded.

At September 30, 2024, the Company had unrealized losses of $0.3 million on U.S. Treasury securities and obligations of U.S. government agencies having a fair value of $20.9 million. These securities are either explicitly or implicitly guaranteed by the full faith and credit of the U.S. government. The Company does not expect individual securities issued by the U.S. Treasury, a U.S. agency, or a sponsored U.S. agency to incur future losses of principal. Based on the assessment of all relevant factors, the Company believes that the unrealized loss positions on these debt securities are a function of changes in investment spreads and interest rate movements and not changes in credit quality, and expects to recover the entire amortized cost basis of these securities. Therefore, at September 30, 2024, no allowance for credit losses has been recorded.

At September 30, 2024, the Company had unrealized losses of $170.2 million on commercial and residential mortgage-backed securities and collateralized mortgage obligations issued by government-sponsored entities having a fair value of $1.1 billion. These securities are either explicitly or implicitly guaranteed by the U.S. government and have a long history of no credit losses. The implied government guarantee of principal and interest payments and the high credit rating of the portfolio provide a sufficient basis for the current expectation that there is no risk of loss if default were to occur. Based on the assessment of all relevant factors, the Company believes that the unrealized loss positions on these debt securities are a function of changes in investment spreads and interest rate movements and not changes in credit quality, and expects to recover the entire amortized cost basis of these securities. Therefore, at September 30, 2024, no allowance for credit losses has been recorded.

At September 30, 2024, the Company had $7.0 million of unrealized losses on private label residential and commercial mortgage-backed securities and collateralized mortgage obligations having a fair value of $106.7 million. The securities have weighted average credit support of 22%. Based on the evaluation of available information relevant to collectibility, the Company believes that the unrealized loss positions on these debt securities are a function of changes in investment spreads and interest rate movements and not changes in credit quality, and expects to recover the entire amortized cost basis of these securities. Therefore, at September 30, 2024, no allowance for credit losses has been recorded.

At September 30, 2024, the Company had $0.2 million of unrealized losses in floating rate collateralized loan obligations (“CLOs”) having a fair value of $61.6 million. CLOs are special purpose vehicles and those in which the Company has invested are nearly all first-lien, broadly syndicated corporate loans across a diversified band of industries while providing support to senior tranche investors. As of September 30, 2024, all positions held by the Company are in AAA and AA tranches, with weighted average credit support of 38% and 30%, respectively. The Company evaluates the securities for potential credit losses by modeling expected loan-level defaults, recoveries, and prepayments for each CLO security. Based on the evaluation of available information relevant to collectibility, the Company believes that the unrealized loss positions on these debt securities are a function of changes in investment spreads and interest rate movements and not changes in credit quality, and expects to recover the entire amortized cost basis of these securities. Therefore, at September 30, 2024, no allowance for credit losses has been recorded.

At September 30, 2024, the Company had $1.2 million of unrealized losses on municipal securities having a fair value of $5.6 million. These securities are highly rated issuances of state or local municipalities, all of which are continuing to make timely contractual payments. Based on the evaluation of available information relevant to collectibility, the Company believes that the unrealized loss positions on these debt securities are a function of changes in investment spreads and interest rate movements and not changes in credit quality, and expects to recover the entire amortized cost basis of these securities. As a result, as of September 30, 2024, no allowance for credit losses has been recorded.

All HTM debt securities are issued by government-sponsored entities, which are either explicitly or implicitly guaranteed by the U.S. government and have a long history of no credit losses. The implied government guarantee of principal and interest payments, and the high credit rating of the HTM portfolio provide sufficient basis for the current expectation that there is no risk of loss if a default were to occur. As a result, as of September 30, 2024, no allowance for credit losses has been recorded. The Company has the intent and ability to hold these securities until maturity.

Included in Other Assets at September 30, 2024 and December 31, 2023 is $77.2 million and $67.7 million, respectively, of FHLB and Federal Reserve Bank (“FRB”) stock stated at par value. The Company has not identified events or changes in circumstances which may have a significant adverse effect on the fair value of these cost method investment securities. Accrued interest receivable on AFS and HTM debt securities of $8.4 million and $1.1 million, respectively, at September 30, 2024, and $7.9 million and $1.1 million, respectively, at December 31, 2023, is included in Other Assets. Also included in Other Assets are investments in CRA-qualified mutual funds carried at fair value of $13.9 million and $13.6 million at September 30, 2024 and December 31, 2023, respectively.

At December 31, 2023, the Company held 11,330 shares of Visa Class B stock. During the nine months ended September 30, 2024, the Company sold all of its Visa Class B stock, receiving net proceeds of $4.1 million. The ownership of Visa stock was related to prior ownership in Visa’s network while Visa operated as a cooperative, and was recorded on the Company’s financial records at a zero basis.

Note 4 –Loans

Loans held for investment are categorized into the following segments:

•Construction and land development: Loans are extended to both commercial and consumer customers which are collateralized by and for the purpose of funding land development and construction projects, including 1-4 family residential, multi-family, and non-farm residential property where the primary source of repayment is from proceeds of the sale, refinancing or permanent financing of the property.

•Commercial real estate - owner occupied: Loans are extended to commercial customers for the purpose of acquiring or refinancing real estate to be occupied by the borrower’s business. These loans are collateralized by the subject property and the repayment of these loans is largely dependent on the performance of the company occupying the property.

•Commercial real estate - non-owner occupied: Loans are extended to commercial customers for the purpose of acquiring or refinancing commercial property where occupancy by the borrower is not their primary intent. These loans are viewed primarily as cash flow loans, collateralized by the subject property, and the repayment of these loans is largely dependent on rental income from third parties or from the sale of the property.

•Residential real estate: Loans are extended to consumer customers and collateralized primarily by 1-4 family residential properties and include fixed and variable rate mortgages, home equity mortgages, and home equity lines of credit. Loans are primarily written based on conventional loan agency guidelines, including loans that exceed agency value limitations. Sources of repayment are largely dependent on the occupant of the residential property.

•Commercial and financial: Loans are extended to commercial customers. The purpose of the loans can be working capital, physical asset expansion, asset acquisition, or other business purposes. Loans may be collateralized by assets owned by the borrower or the borrower’s business. Commercial loans are based primarily on the historical and projected cash flow of the borrower’s business and secondarily on the capacity of credit enhancements, guarantees, and underlying collateral provided by the borrower.

•Consumer: Loans are extended to consumer customers. The segment includes both installment loans and lines of credit which may be collateralized or non-collateralized.

The following tables present net loan balances by segment for portfolio loans, purchased credit deteriorated loans (“PCD”) and loans purchased which are not considered credit deteriorated (“Non-PCD”) as of:

The amortized cost basis of loans included net deferred costs of $44.9 million at September 30, 2024 and $43.1 million at December 31, 2023. At September 30, 2024, the remaining fair value adjustments on acquired loans were $141.8 million, or 4.5% of the outstanding acquired loan balances, compared to $174.0 million, or 4.8% of the acquired loan balances at December 31, 2023. The discount is accreted into interest income over the remaining lives of the related loans on a level yield basis. During the nine months ended September 30, 2024, $9.1 million in loans previously held for investment were sold, resulting in a net gain of $0.9 million.

Accrued interest receivable is included within Other Assets and was $38.8 million and $39.4 million at September 30, 2024 and December 31, 2023, respectively.

The following tables present the status of net loan balances as of September 30, 2024 and December 31, 2023.

All interest accrued but not received for loans placed on nonaccrual is reversed against interest income. Interest subsequently received on such loans is accounted for under the cost-recovery method, whereby interest income is not recognized until the loan balance is paid down to zero. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current, and future payments are reasonably assured. The Company recognized interest income of $0.2 million and $0.4 million on nonaccrual loans during the three months ended September 30, 2024 and September 30, 2023, respectively. The Company recognized $1.1 million and $0.8 million in interest income on nonaccrual loans during the nine months ended September 30, 2024 and September 30, 2023, respectively.

The following tables present net balances of loans on nonaccrual status and the related allowance for credit losses, if any, as of:

Loans by Risk Rating

The Company utilizes an internal asset classification system as a means of identifying problem and potential problem loans. The following classifications are used to categorize loans under the internal classification system:

•Pass: Loans that are not problem loans or potential problem loans are considered to be pass-rated.

•Special Mention: Loans that do not currently expose the Company to sufficient risk to warrant classification in the Substandard or Doubtful categories, but possess weaknesses that deserve management’s close attention are deemed to be Special Mention.

•Substandard: Loans with the distinct possibility that the Company will sustain some loss if the deficiencies are not corrected.

•Doubtful: Loans that have all the weaknesses inherent in those classified Substandard with the added characteristic that the weakness present makes collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable.

The following tables present the risk rating of loans and year-to-date 1 gross charge offs by year of origination as of:

1 Represents gross charge-offs for the nine months ended September 30, 2024.

1 Represents gross charge-offs for the year ended December 31, 2023.

Troubled Borrower Modifications

The following table presents the amortized cost of troubled borrower modification (“TBM”) loans that were modified during the nine months ended September 30, 2024. There were five loans with an amortized cost of $0.9 million modified as a TBM during the nine months ended September 30, 2023.

The following table presents the payment status of TBM loans that were modified in the twelve months prior to September 30, 2024.

TBM loans modified in the prior 12 months with a payment default during the nine months ending September 30, 2024 were immaterial.

Note 5 –Allowance for Credit Losses

Activity in the allowance for credit losses is summarized as follows:

Management establishes the allowance using relevant available information from both internal and external sources, relating to past events, current conditions, and reasonable and supportable forecasts. Forecast data is sourced from Moody’s Analytics (“Moody’s”), a firm widely recognized for its research, analysis, and economic forecasts. The forecasts of future economic conditions are over the expected remaining life of the loan using economic forecasts that revert to long-term historical averages over time.

As of September 30, 2024 and December 31, 2023, the Company utilized a multiple scenario model comprised of a blend of Moody’s economic scenarios and considered the uncertainty associated with the assumptions in the scenarios, including continued actions taken by the Federal Reserve with regard to monetary policy and interest rates and the potential impact of those actions. Outcomes could differ from the scenarios utilized, and the Company incorporated qualitative considerations reflecting the risk of uncertain economic conditions, and for additional dimensions of risk that may not be captured in the quantitative model.

The following section discusses changes in the level of the allowance for credit losses for the three months ended September 30, 2024.

The allowance decreased $1.2 million, or 0.8%, during the third quarter of 2024 to $140.5 million, or 1.38% of loans held for investment as of September 30, 2024.

In the Construction and Land Development segment, the increase in allowance is due to continued uncertainty in connection with commercial real estate markets. In this segment, the primary source of repayment is typically from proceeds of the sale or permanent financing of the underlying property; therefore, industry and collateral type and estimated collateral values are among the relevant factors in assessing expected losses.

In the Commercial Real Estate - Owner-Occupied segment, the allowance increased nominally due to an increase in loan balances and continued uncertainty in connection with commercial real estate valuations broadly and uncertainty associated with the economy. Risk characteristics include, but are not limited to, collateral type, note structure and loan seasoning.

In the Commercial Real Estate - Non-Owner-Occupied segment, the allowance increased slightly driven by higher loan balances and was partially offset by the charge-off of one nonaccrual loan. Repayment is often dependent upon rental income from the successful operation of the underlying property or from the sale of the property. Loan performance may be adversely affected by general economic conditions or conditions specific to the real estate market, including property types. Collateral type, note structure, and loan seasoning are among the risk characteristics analyzed for this segment.

The Residential Real Estate segment includes first mortgages secured by residential property, and home equity lines of credit. Allowance levels were essentially flat from last quarter. Risk characteristics considered for this segment include, but are not limited to, borrower FICO score, lien position, loan to value ratios, and loan seasoning.

In the Commercial and Financial segment, borrowers are primarily small to medium sized professional firms and other businesses, and loans are generally supported by projected cash flows of the business, collateralized by business assets, and/or guaranteed by the business owners. The decrease in the allowance is primarily driven by the charge-off of one nonaccrual relationship that was previously individually reserved. Industry, collateral type, estimated collateral values, and loan seasoning are among the relevant factors in assessing expected losses.

Consumer loans include installment and revolving lines, loans for automobiles, boats, and other personal or family purposes. Risk characteristics considered for this segment include, but are not limited to, collateral type, loan to value ratios, loan seasoning and FICO score. The decrease in allowance for consumer loans was driven by lower loan balances and improved economic forecasts.

Note 6 –Derivatives

Interest Rate Contracts

The Company offers interest rate swaps when requested by customers to allow them to hedge the risk of rising interest rates on their variable rate loans. Upon entering into these swaps, the Company enters into offsetting positions with counterparties in order to minimize the interest rate risk. These back-to-back swaps are freestanding financial derivatives with the fair values reported in Other Assets and Other Liabilities. The Company is party to master netting arrangements with its financial institution counterparties; however, the Company does not offset assets and liabilities under the arrangements for financial statement presentation purposes. Gains and losses on these back-to-back swaps, which offset, are recorded through noninterest income.

Interest Rate Swaps Designated as Fair Value Hedges

The Company has entered into interest rate swap contracts to hedge the risk of changes in fair value of the AFS securities portfolio due to changes in the Secured Overnight Financing Rate (“SOFR”). The Company considers these derivatives to be highly effective at offsetting changes in interest rates and assesses the effectiveness on a quarterly basis. The effect of changes in interest rates on the fair value of these derivative contracts is recognized in other comprehensive income. These derivative instruments are primarily for risk management purposes. For the three and nine months ended September 30, 2024, the Company recognized, through other comprehensive income, net losses of $2.8 million and $2.0 million, respectively, and reclassified net gains of $0.3 million in each period out of accumulated other comprehensive income into interest income. For each of the three and nine months ended September 30, 2023, the Company recognized nominal amounts through other comprehensive income, and reclassified $0.2 million and $0.5 million, respectively, out of accumulated other comprehensive income into interest income.

The Company has entered into interest rate swap contracts to hedge the risk of changes in the fair value of a pool of residential mortgages due to changes in SOFR. These fair value hedges utilize the portfolio layer method. The Company considers these derivatives to be highly effective at offsetting changes in interest rates and assesses the effectiveness on a quarterly basis. The effect of changes in interest rates on the fair value of these derivative contracts is recognized in interest income. These derivative instruments are primarily for risk management purposes. For the three and nine months ended September 30, 2024, the Company recognized gains through interest income of $0.9 million and $1.8 million, respectively.

The following table presents amounts recorded on the Consolidated Balance Sheet related to cumulative basis adjustments for fair value hedges.

Note 7 –Securities Sold Under Agreements to Repurchase

Securities sold under agreements to repurchase are accounted for as secured borrowings. For securities sold under agreements to repurchase, the Company is required to pledge collateral with value sufficient to fully collateralize borrowings. Company securities pledged were as follows by collateral type and maturity as of:

Note 8 –Regulatory Capital

The Company is well-capitalized and at September 30, 2024, the Company and the Company’s principal banking subsidiary, Seacoast Bank, exceeded the Common Equity Tier 1 “(CET1)” capital ratio regulatory threshold of 6.5% for well-capitalized institutions under the Basel III standardized transition approach, as well as risk-based and leverage ratio requirements for well-capitalized banks under the regulatory framework for prompt corrective action.

Note 9 –Contingent Liabilities

The Company and its subsidiaries, because of the nature of their business, are at all times subject to numerous legal actions, threatened or filed. Management presently believes that none of the legal proceedings to which it is a party are likely to have a materially adverse effect on the Company’s consolidated financial condition, operating results or cash flows.

Note 10 –Fair Value

Under ASC Topic 820, fair value measurements for items measured at fair value on a recurring and nonrecurring basis at September 30, 2024 and December 31, 2023 included:

Loans and other real estate owned: Fair values of collateral-dependent real estate loans and other real estate owned are based on recent real estate appraisals less estimated costs of sale. Evaluations may use either a single valuation approach or a combination of approaches, such as comparative sales, cost and/or income approach. Adjustments to comparable sales may be made by an appraiser to reflect local market conditions or other economic factors and may result in changes in the fair value of an asset over time but none were made by management. As such, the fair values of these loans and properties are considered Level 3 in the fair value hierarchy. Collateral-dependent loans measured at fair value totaled $6.1 million with a specific reserve of $2.1 million at September 30, 2024, compared to $17.8 million with a specific reserve of $2.6 million at December 31, 2023.

For recurring fair value measurements, transfers between levels of the fair value hierarchy are recognized on the actual date of the event or circumstances that caused the transfer, which generally coincides with the Company’s monthly and/or quarterly valuation process. During the nine months ended September 30, 2024, there were no such transfers.

For additional information on the valuation techniques and significant inputs for Level 2 and Level 3 assets and liabilities that are measured at fair value on a recurring basis, see “Note 16 - Fair Value” of the Annual Report on Form 10-K for the year ended December 31, 2023.

The carrying amount and fair value of the Company’s other financial instruments that were not disclosed previously in the balance sheet and for which carrying amount is not fair value as of September 30, 2024 and December 31, 2023 is as follows:

The short maturity of Seacoast’s assets and liabilities results in a significant number of financial instruments whose fair value equals or closely approximates carrying value. Such financial instruments are reported in the following balance sheet captions: cash and due from banks, interest bearing deposits with other banks, and securities sold under agreements to repurchase.

The following methods and assumptions were used to estimate the fair value of each class of financial instrument for which it is practicable to estimate that value at September 30, 2024 and December 31, 2023:

Held-to-maturity debt securities: These debt securities are reported at fair value utilizing Level 2 inputs. The estimated fair value of a security is determined based on market quotations when available or, if not available, by using quoted market prices for similar securities, pricing models or discounted cash flow analyses, using observable market data where available.

The Company reviews the prices supplied by independent pricing services, as well as their underlying pricing methodologies, for reasonableness and to ensure such prices are aligned with traditional pricing matrices. From time to time, the Company will validate, on a sample basis, prices supplied by the independent pricing service by comparison to prices obtained from other brokers and third-party sources or derived using internal models.

Loans: Fair values are estimated for portfolios of loans with similar financial characteristics. Loans are segregated by type, such as commercial or mortgage. Each loan category is further segmented into fixed and adjustable-rate interest terms as well as performing and nonperforming categories. The fair value of loans is calculated by discounting scheduled cash flows through the estimated life including prepayment considerations, using estimated market discount rates that reflect the risks inherent in the loan. The fair value approach considers market-driven variables including credit related factors and reflects an “exit price” as defined in ASC Topic 820.

Deposit liabilities: The fair value of demand deposits, savings accounts and money market deposits is the amount payable at the reporting date. The fair value of fixed maturity certificates of deposit is estimated using the rates currently offered for funding of similar remaining maturities.

Note 11 –Business Combinations

Acquisition of Professional Holding Corp.

On January 31, 2023, the Company completed its acquisition of Professional Holding Corp. (“Professional”). Simultaneously, upon completion of the merger of Professional and the Company, Professional Bank was merged with and into Seacoast Bank. Prior to the acquisition, Professional Bank operated nine branches across South Florida. The transaction further expanded the Company’s presence in the tri-county South Florida market, which includes Miami-Dade, Broward, and Palm Beach counties, Florida’s largest metropolitan statistical area and the 8th largest in the nation. The Company acquired 100% of the outstanding common stock of Professional. Under the terms of the merger agreement, Professional shareholders received 0.8909 shares of Seacoast common stock for each share of Professional common stock held immediately prior to the merger, and Professional option holders received options to purchase Seacoast common stock, with the number of shares underlying each such option and the applicable exercise price adjusted using the same 0.8909 exchange ratio.

The acquisition of Professional was accounted for under the acquisition method of accounting in accordance with ASC Topic 805, Business Combinations. The Company recognized goodwill of $251.7 million for this acquisition that is nondeductible for tax purposes. Determining fair values of assets and liabilities, especially the loan portfolio, core deposit intangibles, and deferred taxes, is a complicated process involving significant judgment regarding methods and assumptions used to calculate estimated fair values.

As part of the acquisition of Professional, options to purchase shares of Seacoast common stock were granted to replace outstanding Professional options. These options were fully vested upon acquisition. The full value of the replacement options, $10.3 million, was associated with pre-combination service and was therefore included in the calculation of the total purchase consideration.

The table below presents information with respect to the fair value and unpaid principal balance of acquired loans at the acquisition date.

The table below presents the carrying amount of loans for which, at the date of acquisition, there was evidence of more than insignificant deterioration of credit quality since origination:

The acquisition of Professional resulted in the addition of $45.5 million in allowance for credit losses, including the $18.9 million identified in the table above for PCD loans, and $26.6 million for non-PCD loans recorded through the provision for credit losses at the date of acquisition. Included within the $18.9 million initial PCD allowance is $5.5 million recorded as a measurement period adjustment during the three months ended September 30, 2023, reflecting information obtained by the Company relating to events or circumstances existing at the acquisition date.

The Company believes the deposits assumed in the acquisition have an intangible value. In determining the valuation amount, deposits were analyzed based on factors such as type of deposit, deposit retention, interest rates and age of deposit relationships. The core deposit intangible asset acquired from Professional is being amortized over eight years using an accelerated method of amortization.

Acquisition Costs

Acquisition costs were $33.2 million for the nine months ended September 30, 2023.

Note 12 –Subsequent Event

In October 2024, the Company took advantage of favorable market conditions and repositioned a portion of its AFS securities portfolio. Securities with an average book yield of 2.8% were sold, resulting in a pre-tax loss of approximately $8.0 million impacting fourth quarter 2024 results. The proceeds of approximately $113.0 million were reinvested in agency mortgage-backed securities with an average book yield of 5.4%, for an estimated earnback of less than three years.
