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 months ended March 31, 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.

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

Table of Contents

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 months ended March 31, 2024, 327,006 options to purchase shares of the Company’s common stock were anti-dilutive. For the three months ended March 31, 2023, 161,251 options to purchase shares of the Company’s common stock were anti-dilutive.

At March 31, 2024, the Company had unrealized losses of $0.5 million on U.S. Treasury securities and obligations of U.S. government agencies having a fair value of $26.0 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, on March 31, 2024, no allowance for credit losses has been recorded.

At March 31, 2024, the Company had unrealized losses of $211.1 million on commercial and residential mortgage-backed securities and collateralized mortgage obligations issued by government-sponsored entities having a fair value of $1.2 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, on March 31, 2024, no allowance for credit losses has been recorded.

At March 31, 2024, the Company had $10.5 million of unrealized losses on private label residential and commercial mortgage-backed securities and collateralized mortgage obligations having a fair value of $116.0 million. The securities have a weighted average credit support of 23%. 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 March 31, 2024, no allowance for credit losses has been recorded.

At March 31, 2024, the Company had $0.1 million of unrealized losses in floating rate collateralized loan obligations (“CLOs”) having a fair value of $107.8 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 March 31, 2024, all positions held by the Company are in AAA and AA tranches, with weighted average credit support of 41% and 28%, 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 March 31, 2024, no allowance for credit losses has been recorded.

At March 31, 2024, the Company had $1.3 million of unrealized losses on municipal securities having a fair value of $6.0 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 March 31, 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 March 31, 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 March 31, 2024 is $70.6 million 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.

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.

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 reduced 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 $0.2 million in interest income on nonaccrual loans during the three months ended March 31, 2024. The Company recognized $0.1 million in interest income on nonaccrual loans during the three months ended March 31, 2023.

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.

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 March 31, 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, the conflicts in the Middle East and Russia-Ukraine and the magnitude of the resulting market disruptions, and the potential impact of persistent high inflation on the economy. Outcomes in any or all of these factors 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 March 31, 2024.

23

Table of Contents

In the Construction and Land Development segment, the decrease in the allowance is due to a decrease in loan balances. In this segment, the primary source of repayment is typically from proceeds of the sale, refinancing, 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 due to continued uncertainty in connection with commercial real estate valuations broadly, and the collateral values associated with the underlying loans. 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 decrease in the allowance is primarily attributed to improvement in the forecast for macroeconomic factors, partially offset by higher loan balances. Repayment is often dependent upon rental income from the successful operation of the underlying 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. The decrease in the allowance is due to an improvement in the forecast for macroeconomic factors, partially offset by an increase in loan balances. 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 due to a decrease in loan balances. 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 increase in the allowance reflects an increase in expected losses, partly offset by a decrease in loan balances.

Note 6 – Derivatives

Back-to-Back Swaps

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

In the second quarter of 2023, the Company 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 will assess the effectiveness on a quarterly basis. The changes in interest rates affecting the fair value of these derivative contracts are recognized in other comprehensive income. These derivative instruments are primarily for risk management purposes. For the three months ended March 31, 2024, the Company recognized gains through other comprehensive income of $4.0 million and reclassified gains of $61 thousand out of accumulated other comprehensive income into interest income.

The Company 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 values hedges utilize the portfolio layer method. The Company considers these derivatives to be highly effective at offsetting changes in interest rates and will assess the effectiveness on a quarterly basis. The changes in interest rates affecting the fair value of these derivative contracts are recognized in interest income. These derivative instruments are primarily for risk management purposes. For the three months ended March 31, 2024, the Company recognized gains through interest income of $0.4 million.

1 At March 31, 2024, and December 31, 2023, the amortized cost basis and unallocated basis adjustments used in hedging relationships was $657.5 million and $680.6 million, respectively. Refer to “Note 3 - Securities” for a reconciliation of the amortized cost and fair value of AFS securities.
2 These amounts represent the amortized cost basis of closed portfolios used to designate hedging relationships in which the hedged item is the stated amount of assets in the closed portfolios anticipated to be outstanding for the designated hedge period. At March 31, 2024 and December 31, 2023, the portfolio layer method was $200 million, of which $200 million was designated as hedged.

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:

Fair value of pledged securities - overnight and continuous:
Mortgage-backed securities and collateralized mortgage obligations of U.S. government-sponsored entities	$	384,959	$	396,378

Note 8 – Regulatory Capital

The Company is well-capitalized and at March 31, 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.

5Investment in shares of mutual funds that invest primarily in CRA-qualified debt securities, reported at fair value in Other Assets. Recurring fair value basis is determined using market quotations.

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 three months ended March 31, 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 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 March 31, 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 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.

Allowance for credit losses at acquisition	(18,879)
Non-credit related discount	(12,361)
Total PCD loans acquired	$	123,791

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 June 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 included in the Company's income statement for the three months ended March 31, 2023 were $17.5 million.

Net Interest Income and Margin

Net interest income for the first quarter of 2024 totaled $105.1 million, a decrease of $5.7 million, or 5%, compared to the fourth quarter of 2023, and a decrease of $26.1 million, or 20%, compared to the first quarter of 2023. The decrease from the prior quarter reflects higher interest expense on deposits driven by higher deposit costs attributed in part to overall growth in deposit balances. The decrease was partially offset by higher yields on loans and securities. The decrease from the prior year is primarily due to the higher cost of deposits.

Table of Contents

Net interest income (on a fully taxable equivalent basis)1 for the first quarter of 2024 was $105.3 million, a decrease of $5.7 million, or 5%, compared to the fourth quarter of 2023, and a decrease of $26.1 million, or 20%, compared to the first quarter of 2023. Accretion on acquired loans totaled $10.6 million for the first quarter of 2024, compared to $11.3 million for the fourth quarter of 2023, and $15.9 million for the first quarter of 2023.

Net interest margin (on a fully tax equivalent basis)1 was 3.24% in the first quarter of 2024, compared to 3.36% in the fourth quarter of 2023, and 4.31% in the first quarter of 2023. The decrease during the first quarter of 2024 was largely driven by the growth in deposit costs. Compared to the fourth quarter of 2023, securities yields expanded five basis points to 3.47% and loan yields increased to 5.90% during the first quarter of 2024. The effect on net interest margin of accretion of purchase discounts on acquired loans were increases of 33 basis points in the first quarter of 2024, 34 basis points in the fourth quarter of 2023, and 53 basis points in the first quarter of 2023. The cost of deposits was 2.19% in the first quarter of 2024, compared to 2.00% in the fourth quarter of 2023, and 0.77% in the first quarter of 2023. For the first quarter of 2024, the higher cost of deposits reflects the impact of the continuing elevated interest rate environment.

The following table details the trend for net interest income and margin results (on a tax equivalent basis)1, the yield on earning assets and the rate paid on interest bearing liabilities for the periods specified:

(In thousands, except ratios)	Net Interest Income1		Net Interest Margin1		Yield on Earning Assets1		Rate on Interest Bearing Liabilities

Noninterest Income

Noninterest income totaled $20.5 million for the first quarter of 2024, an increase of $3.2 million, or 18%, compared to the fourth quarter of 2023 and a decrease of $1.9 million, or 9% from the first quarter of 2023.

Noninterest income is detailed as follows:

	First		Fourth		First
	Quarter		Quarter		Quarter
(In thousands)	2024		2023		2023
Service charges on deposit accounts	$	4,960	$	4,828	$	4,242
Interchange income	1,888		2,433		4,694
Wealth management income	3,540		3,261		3,063
Mortgage banking fees	381		378		426
Insurance agency income	1,291		1,066		1,101
SBA gains	739		921		322
BOLI income	2,264		2,220		1,916
Other income	5,205		4,668		6,574
	20,268		19,775		22,338
Securities gains (losses), net	229		(2,437)		107
Total	$	20,497	$	17,338	$	22,445

Service charges on deposits were $5.0 million in the first quarter of 2024, compared to $4.8 million in the fourth quarter of 2023, and $4.2 million in the first quarter of 2023. The increase in fees primarily reflects the benefit of an expanded deposit base and the continued expansion of commercial treasury management services and new customer acquisition.

Interchange income decreased to $1.9 million for the first quarter of 2024, compared to $2.4 million for the fourth quarter of 2023, and $4.7 million for the first quarter of 2023. The decrease in interchange income compared to the prior quarter is due to an annual volume-based incentive earned from the payment network provider in the previous quarter. The decrease compared to the prior year quarter is due to the impact of the Durbin amendment, which became effective for the first time for the Company on July 1, 2023, limiting network interchange fees earned on debit card transactions.

Wealth management income, including trust fees and brokerage commissions and fees, was $3.5 million in the first quarter of 2024, compared to $3.3 million for the fourth quarter of 2023 and $3.1 million for the first quarter of 2023. The wealth management division continues to demonstrate success in building relationships, and during the first quarter of 2024, assets under management grew $160 million, or 9%, to $1.9 billion.

Insurance agency income increased $0.2 million, or 21%, compared to the fourth quarter of 2023 and totaled $1.3 million.

Bank owned life insurance (“BOLI”) income was $2.3 million for the first quarter of 2024 compared to $2.2 million for the fourth quarter of 2023 and $1.9 million for the first quarter of 2023. The increase of $0.3 million, or 18%, compared to the first quarter of 2023 is attributed to additions, including those from bank acquisitions.

Other income was $5.2 million in the first quarter of 2024, an increase of $0.5 million, or 12%, compared to the fourth quarter of 2023, and a decrease of $1.4 million, or 21% compared to the first quarter of 2023. The increase compared to the prior quarter reflects higher marine and aircraft loan production sold, as well as higher SBIC income. The decrease compared to the first quarter of 2023 was attributed to BOLI death benefits of $2.1 million in the first quarter of 2023.

Net securities gains of $0.2 million in the first quarter of 2024 include gains of $4.1 million on the sale of the Company’s holdings of Visa Class B stock. This was largely offset by losses of $3.8 million on the sale of $86.8 million, or 3%, of the bank’s investment securities portfolio. The proceeds were reinvested at a yield of 5.53%, with an expected earnback on the trade of 1.9 years.

Noninterest Expenses

Noninterest expense for the first quarter of 2024 totaled $90.4 million, an increase of $4.0 million, or 5%, compared to the fourth quarter of 2023, and a decrease of $17.1 million, or 16%, from the first quarter of 2023. Noninterest expenses are detailed as follows:

	First		Fourth		First

Other	6,532		6,542		7,137
Total	$	90,371	$	86,367	$	107,475

Salaries and wages totaled $40.3 million for the first quarter of 2024, $38.4 million for the fourth quarter of 2023, and $47.6 million for the first quarter of 2023. The increase compared to the fourth quarter of 2023 reflects severance-related costs arising from reductions in the workforce early in the first quarter of 2024. The decrease compared to the first quarter of 2023 reflects $4.2 million in merger-related expenses during the first quarter of 2023. The first quarter of 2023 also included expenses related to the net addition of branch locations and associates, as well as new bankers and operational staff associated with acquisitions.

During the first quarter of 2024, employee benefit costs, which include costs associated with the Company’s self-funded health insurance benefits, 401(k) plan, payroll taxes, and unemployment compensation, were $7.9 million, an increase of $1.2 million, or 18%, compared to the fourth quarter of 2023, and a decrease of $0.7 million, or 8%, compared to the first quarter of 2023. The increase compared to the fourth quarter of 2023 reflects higher seasonal payroll taxes and 401(k) contributions. The decrease compared to the first quarter of 2023 is related to reductions in the workforce.

The Company utilizes third parties for its core data processing systems. Ongoing data processing costs are directly related to the number of transactions processed and the negotiated rates associated with those transactions. Outsourced data processing costs totaled $12.1 million, $8.6 million, and $14.6 million for the first quarter of 2024, fourth quarter of 2023, and first quarter of 2023, respectively. The increased costs in the first quarter of 2024 are attributed to $4.1 million in charges associated with contract terminations and modifications to consolidate systems, which should lead to lower ongoing operating expenses.

Total occupancy, furniture and equipment expenses were $10.0 million in the first quarter of 2024, $9.5 million in the fourth quarter of 2023, and $10.3 million in the first quarter of 2023. Expenses in the first quarter of 2024 included charges of $0.8 million associated with early lease terminations and consolidation of locations as part of the Company’s expense reduction initiative.

Marketing expenses totaled $2.7 million in the first quarter of 2024, $3.0 million in the fourth quarter of 2023, and $2.2 million in the first quarter of 2023.

Legal and professional fees for the first quarter of 2024 were $2.2 million, a decrease of $1.1 million, or 35%, compared to the fourth quarter of 2023, and a decrease of $5.3 million, or 71%, compared to the first quarter of 2023. There were no acquisition-related expenses in the first quarter of 2024 or the fourth quarter of 2023, compared to $4.8 million in the first quarter of 2023.

Provision for Credit Losses

The provision for credit losses was $1.4 million for the first quarter of 2024, compared to $4.0 million for the fourth quarter of 2023, and $31.6 million for the first quarter of 2023. The first quarter of 2023 included a $26.6 million day-one provision associated with the acquisition of Professional.

Income Taxes

For the first quarter of 2024, the Company recorded tax expense of $7.8 million, compared to $8.3 million in the fourth quarter of 2023 and $2.7 million in the first quarter of 2023. Lower income tax expense in the first quarter of 2024 compared to the fourth quarter of 2023 and the first quarter of 2023 is primarily due to lower pre-tax income.

Explanation of Certain Unaudited Non-GAAP Financial Measures

This report contains financial information determined by methods other than Generally Accepted Accounting Principles (“GAAP”). The financial highlights provide reconciliations between GAAP and adjusted financial measures including net income, fully taxable equivalent net interest income, noninterest income, noninterest expense, tax adjustments, net interest margin and other financial ratios. Management uses these non-GAAP financial measures in its analysis of the Company’s performance and believes these presentations provide useful supplemental information, and a clearer understanding of the Company’s performance. The Company believes the non-GAAP measures enhance investors’ understanding of the Company’s business and performance and if not provided would be requested by the investor community. These measures are also useful in understanding performance trends and facilitate comparisons with the performance of other financial institutions. The limitations associated with operating measures are the risk that persons might disagree as to the appropriateness of items comprising these measures and that different companies might define or calculate these measures differently. The Company provides reconciliations between GAAP and these non-GAAP measures. These disclosures should not be considered an alternative to GAAP.

During the three months ended March 31, 2024, the Company recognized a $4.1 million gain on the opportunistic sale of Visa Class B shares. The gain was offset by a partial repositioning of the securities portfolio, in which $86.8 million of securities were sold, with $3.8 million in realized losses. Additionally, during the three months ended March 31, 2024, there were $261.0 million of debt securities purchased and $61.2 million in paydowns and maturities over the same period.

The credit quality of the Company’s securities holdings is primarily investment grade. U.S. Treasury securities, obligations of U.S. government agencies, and obligations of U.S. government sponsored entities totaled $2.2 billion, or 83%, of the total portfolio.

The portfolio includes $136.6 million, with a fair value of $126.2 million, in private label residential and commercial mortgage-backed securities and collateralized mortgage obligations. Included are $127.0 million, with a fair value of $116.9 million, in private label residential securities with weighted average credit support of 23%. The collateral underlying these mortgage investments includes both fixed-rate and adjustable-rate residential mortgage loans. Commercial securities totaled $9.6 million, with a fair value of $9.2 million. These securities have weighted average credit support of 26%. The collateral underlying these mortgages are primarily pooled multifamily loans.

The Company also has invested $284.7 million in floating rate collateralized loan obligations. Collateralized loan obligations are special purpose vehicles that purchase first lien broadly syndicated corporate loans while providing support to senior tranche investors. As of March 31, 2024, all of the Company’s collateralized loan obligations were in AAA/AA tranches with weighted average credit support of 34%. The Company utilizes credit models with assumptions of loan level defaults, recoveries, and prepayments to evaluate each security for potential credit losses. The result of this analysis did not indicate expected credit losses.

HTM securities consist solely of mortgage-backed securities and collateralized mortgage obligations guaranteed by U.S. government-sponsored entities, each of which is expected to recover any price depreciation over its holding period as the debt securities move to maturity. The Company has significant liquidity and available borrowing capacity through other sources if needed, and has the intent and ability to hold these investments to maturity.

At March 31, 2024, the Company has determined that all debt securities in an unrealized loss position are the result of both broad investment type spreads and the current interest rate environment. Management believes that each investment will recover any price depreciation over its holding period as the debt securities move to maturity, and management has the intent and ability to hold these investments to maturity if necessary. Therefore, at March 31, 2024, no allowance for credit losses has been recorded.

Loan Portfolio

Loans, net of unearned income and excluding the allowance for credit losses, were $10.0 billion at March 31, 2024, an $84.9 million, or 1%, decrease from December 31, 2023.

The Company remains committed to sound risk management procedures. Portfolio diversification in terms of asset mix, industry, and loan type has been and continues to be an important element of the Company’s lending strategy. The average loan size is only $332 thousand, and the average commercial loan size is only $742 thousand at March 31, 2024, reflecting the Company’s longtime focus on granularity and on creating valuable customer relationships. Lending policies contain guardrails that pertain to lending by type of collateral and purpose, along with limits regarding loan concentrations and the principal amount of loans. The Company’s exposure to commercial real estate lending remains well below regulatory limits (see “Loan Concentrations”).

CRE non-owner occupied loans increased by $48.4 million in the three months ended March 31, 2024, totaling $3.37 billion at March 31, 2024 compared to $3.32 billion at December 31, 2023. Non-owner occupied CRE loans are collateralized by properties where the source of repayment is typically from the sale or lease of the property. Within the non-owner occupied CRE portfolio, the largest segment is Retail properties, which totaled approximately $1.12 billion at March 31, 2024.

Table of Contents

This segment targets grocery or credit tenant-anchored shopping plazas, single credit tenant retail buildings, smaller outparcels, and other small retail units. Loans in this segment have a weighted average loan to value of 51% and an average loan size of $2.1 million. The second-largest segment in the non-owner occupied CRE portfolio is Office properties, which totaled $565.1 million at March 31, 2024. This segment targets low to mid-rise suburban offices and is broadly diversified across many types of professional services. There is limited exposure to central business districts. Loans in this segment have a weighted average loan to value of 55% and an average loan size of $1.6 million.

Owner-occupied CRE loans decreased by $14.2 million in the three months ended March 31, 2024 to $1.7 billion. Owner-occupied CRE is used by the owner, where the primary source of repayment is the cash flow from business operations housed within the property.

Commercial and financial loans are extended to commercial customers for working capital, physical asset expansion, asset acquisition or other business purposes. Balances decreased $41.7 million, or 3%, from December 31, 2023, totaling $1.6 billion at March 31, 2024.

Residential mortgage loans increased $75.7 million to $2.5 billion during the three months ended March 31, 2024. Included in the balance as of March 31, 2024, were $1.0 billion of fixed rate mortgages, $932.3 million of adjustable rate mortgages and $475.9 million in primarily floating rate home equity lines of credit (“HELOCs”), compared to $1.0 billion, $865.2 million and $488.2 million, respectively, at December 31, 2023. Borrowers in the residential real estate portfolio have an average credit score of 752. Substantially all residential originations have been underwritten to conventional loan agency standards, including loan balances that exceed agency value limitations. The average LTV of our HELOC portfolio is 63%, with 33% of the loans being in first lien position at March 31, 2024, compared to an average LTV of 63%, with 35% of the portfolio being in the first lien position at December 31, 2023.

The Company also provides consumer loans, which include installment loans, auto loans, marine loans, and other consumer loans, which decreased $8.8 million, or 4%, to total $242.7 million at March 31, 2024, compared to $251.6 million at December 31, 2023.

Consumer pipeline at period end	25,057		18,745		38,742
Consumer originations	48,244		61,847		110,602

Commercial and commercial real estate originations during the first quarter of 2024 were $260.0 million, a decrease of $74.2 million, or 22%, compared to the fourth quarter of 2023, and a decrease of $60.2 million, or 19%, compared to the first quarter of 2023. Lower originations compared to the fourth quarter of 2023 were consistent with typical seasonality. Lower originations compared to the first quarter of 2023 were largely the result of the impact of higher rates on customer demand. Commercial and commercial real estate pipelines were $498.6 million as of March 31, 2024, an increase of 63% from $306.5 million at December 31, 2023, and an increase of 72% from $289.2 million at March 31, 2023.

SBA originations totaled $18.9 million during the first quarter of 2024, a decrease of $6.1 million compared to the fourth quarter of 2023, and an increase of $17.5 million compared to the first quarter of 2023.

Residential loans originated for sale in the secondary market totaled $4.6 million in the first quarter of 2024, compared to $15.6 million in the fourth quarter of 2023 and $13.9 million in the first quarter of 2023. Residential saleable pipelines were $9.3 million as of March 31, 2024, compared to $2.7 million as of December 31, 2023 and $6.6 million as of March 31, 2023.

The pipeline of residential loans intended to be retained in the portfolio was $24.4 million as of March 31, 2024, compared to $44.4 million as of December 31, 2023, and $48.4 million as of March 31, 2023.

Consumer originations, which include HELOCs, totaled $48.2 million during the first quarter of 2024, compared to $61.8 million in the fourth quarter of 2023 and $110.6 million in the first quarter of 2023. The consumer pipeline was $25.1 million as of March 31, 2024, compared to $18.7 million as of December 31, 2023 and $38.7 million at March 31, 2023.

Loan Concentrations

The Company has developed guardrails to manage loan types that are most impacted by stressed market conditions to minimize credit risk concentration to capital. Outstanding balances for commercial and commercial real estate loan relationships greater than $10 million totaled $2.3 billion, representing 23% of the total portfolio, at both March 31, 2024 and December 31, 2023. The Company’s ten largest commercial and commercial real estate funded and unfunded relationships at March 31, 2024 aggregated to $552.1 million, of which $386.8 million was funded, compared to $505.7 million at December 31, 2023, of which $348.3 million was funded.

Concentrations in construction and land development loans and CRE loans are maintained well below regulatory limits. Construction and land development and CRE loan concentrations as a percentage of subsidiary bank total risk based capital were 39% and 236%, respectively, at March 31, 2024, compared to 48% and 244%, respectively, at December 31, 2023. Regulatory guidance suggests limits of 100% and 300%, respectively. On a consolidated basis, construction and land development and commercial real estate loans represent 36% and 222%, respectively, of total consolidated risk based capital as of March 31, 2024. To determine these ratios, the Company defines CRE in accordance with the guidance on “Concentrations in Commercial Real Estate Lending” (the “Guidance”) issued by the federal bank regulatory agencies in 2006 (and reinforced in 2015), which defines CRE loans as exposures secured by land development and construction, including 1-4 family residential construction, multi-family property, and non-farm nonresidential property where the primary or a significant source of repayment is derived from rental income associated with the property (i.e., loans for which 50 percent or more of the source of repayment comes from third party, non-affiliated, rental income) or the proceeds of the sale, refinancing, or permanent financing of the property. Loans to real estate investment trusts (“REITs”) and unsecured loans to developers that closely correlate to the inherent risks in CRE markets would also be considered CRE loans under the Guidance. Loans on owner-occupied CRE are generally excluded. In addition, the Company is subject to a geographic concentration of credit because it primarily operates in Florida.

Nonperforming Loans, Troubled Borrower Modifications, Other Real Estate Owned and Credit Quality

Nonperforming assets (“NPAs”) at March 31, 2024 totaled $84.5 million, and were comprised of $77.2 million of nonaccrual loans, and $7.3 million of other real estate owned (“OREO”), including $7.0 million of branches taken out of service. Overall, NPAs increased $11.9 million, or 16%, from $72.7 million as of December 31, 2023. Nonperforming assets to total assets at March 31, 2024 increased to 0.57% from 0.50% at December 31, 2023.

Compared to December 31, 2023, nonaccrual loans increased $12.1 million, or 19%. Approximately 58% of nonaccrual loans were secured with real estate at March 31, 2024. Nonperforming loans to total loans outstanding at March 31, 2024 increased to 0.77% from 0.65% at December 31, 2023. See the tables below for the payment status of nonaccrual loans.

In accordance with regulatory reporting requirements, loans are placed on nonaccrual following the Retail Classification of Loan interagency guidance. The accrual of interest is generally discontinued on loans, except consumer loans, that become 90 days past due as to principal or interest unless collection of both principal and interest is assured by way of collateralization, guarantees or other security. Consumer loans that become 120 days past due are generally charged off. The loan carrying value is analyzed and any changes are appropriately made as described above quarterly.

In certain circumstances, the Company provides modifications of loans to borrowers experiencing financial difficulty, which the Company refers to as troubled borrower modifications (“TBMs”). Loans that were modified as TBMs during the three months ended March 31, 2024 are included in “Note 4 - Loans”.

Allowance for Credit Losses on Loans

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. The forecasts of future economic conditions are over a period that has been deemed reasonable and supportable, and in segments where it can no longer develop reasonable and supportable forecasts, the Company reverts to longer-term historical loss experience to estimate losses over the remaining life of the loans. Expected credit losses are estimated over the contractual term of the loans, adjusted for expected prepayments.

During the three months ended March 31, 2024, the Company recorded provision expense of $1.4 million. The Company reported net charge-offs for the three months ended March 31, 2024 of $3.6 million.

The ratio of allowance for credit losses to total loans was 1.47% at March 31, 2024, 1.48% at December 31, 2023, and 1.54% at March 31, 2023.

Cash and Cash Equivalents and Liquidity Risk Management

Liquidity risk involves the risk of being unable to fund assets with the appropriate duration and rate-based liability, as well as the risk of not being able to meet unexpected cash needs. Liquidity planning and management are necessary to ensure the ability to fund operations cost effectively and to meet current and future potential obligations such as loan commitments and unexpected deposit outflows.

Funding sources primarily include customer-based deposits, collateral-backed borrowings, brokered deposits, cash flows from operations, cash flows from the loan and investment portfolios and asset sales, primarily secondary marketing for residential real estate mortgages. Cash flows from operations are a significant component of liquidity risk management and the Company considers both deposit maturities and the scheduled cash flows from loan and investment maturities and payments when managing risk.

Cash and cash equivalents, including interest bearing deposits, totaled $682.7 million at March 31, 2024, compared to $447.2 million at December 31, 2023. Higher cash and cash equivalent balances at March 31, 2024 are consistent with the Company’s strategic balance sheet management.

Deposits are a primary source of liquidity. The stability of this funding source is affected by numerous factors, including returns available to customers on alternative investments, the quality of customer service levels, perception of safety and competitive forces. Total uninsured deposits were estimated to be $4.2 billion at March 31, 2024, representing 35% of overall deposit accounts. This includes public funds under the Florida Qualified Public Depository program, which provides loss protection to depositors beyond FDIC insurance limits. Excluding such balances, the uninsured and uncollateralized deposits were 29% of total deposits at March 31, 2024. The Company has liquidity sources as discussed below, including cash and lines of credit with the FRB and FHLB, that represent 138% of uninsured deposits, and 164% of uninsured and uncollateralized deposits.

In addition to $682.7 million in cash and cash equivalents at March 31, 2024, the Company had $5.1 billion in available borrowing capacity, including $4.4 billion in available collateralized lines of credit, $391.3 million of unpledged debt securities available as collateral for potential additional borrowings, and available unsecured lines of credit of $300.0 million. The Company may also access funding by acquiring brokered deposits. Brokered deposits at March 31, 2024 totaled $142.7 million compared to $122.3 million at December 31, 2023.

Contractual maturities for assets and liabilities are reviewed to meet current and expected future liquidity requirements. Sources of liquidity are maintained through a portfolio of high quality marketable assets, such as residential mortgage loans, debt securities available-for-sale and interest-bearing deposits. The Company is also able to provide short-term financing of its activities by selling, under an agreement to repurchase, United States Treasury and Government agency debt securities not pledged to secure public deposits or trust funds.

The Company has traditionally relied upon dividends from Seacoast Bank and securities offerings to provide funds to pay the Company’s expenses and to service the Company’s debt. During the first quarter of 2024, Seacoast Bank distributed $15.1 million to the Company and, at March 31, 2024, is eligible to distribute dividends to the Company of approximately $138.7 million without prior regulatory approval. At March 31, 2024, the Company had cash and cash equivalents at the parent of approximately $101.5 million, compared to $101.7 million at December 31, 2023.

The Company benefits from a diverse and granular deposit base that serves as a significant source of strength. Total deposits increased $238.9 million, or 2%, to $12.0 billion at March 31, 2024 compared to December 31, 2023.

Noninterest demand deposits represented 30% of total deposits at both March 31, 2024 and December 31, 2023. Transaction account balances (noninterest demand and interest-bearing demand) represented 52% of total deposits at March 31, 2024, compared to 54% at December 31, 2023.

Customer sweep accounts totaled $326.7 million at March 31, 2024, decreasing $47.8 million, or 13%, from December 31, 2023. Repurchase agreements are offered by Seacoast to select customers who wish to sweep excess balances on a daily basis for investment purposes.

At March 31, 2024 and December 31, 2023, long-term debt included $72.3 million and $72.2 million, respectively, related to trust preferred securities issued by trusts organized or acquired by the Company. At March 31, 2024, the average interest rate in effect on our outstanding subordinated debt related to trust preferred securities was 7.29%, compared to 7.34% at December 31, 2023. All trust preferred securities are guaranteed by the Company on a junior subordinated basis. Under Basel III and FRB rules, qualified trust preferred securities and other restricted capital elements can be included as Tier 1 capital, within limitations. The Company believes that its trust preferred securities qualify under these capital rules.

In 2022, the Company acquired $12.3 million in senior debt through the acquisition of Apollo Bancshares, Inc. Contractual interest is paid on a semiannual basis at a fixed rate of 5.50% until April 30, 2025, at which point the rate converts to a floating rate of 3-month SOFR plus 533 basis points. The debt was recorded at fair value, resulting in a $0.4 million premium that is being amortized into interest expense over the remaining term to maturity.

In 2023, the Company acquired $25.0 million in subordinated debt through the acquisition of Professional that qualifies as Tier 2 Capital. Contractual interest is paid on a semiannual basis at a fixed interest rate of 3.375% until January 30, 2027, at which point the rate converts to a 3-month SOFR rate plus 203 basis points paid quarterly. The debt was recorded at fair value, resulting in a $3.9 million discount that is being accreted into interest expense over the remaining term to maturity.

Federal Home Loan Bank advances totaled $110.0 million at March 31, 2024 with a weighted average interest rate of 4.15%, compared to $50.0 million at December 31, 2023 with an interest rate of 3.23%.

Off-Balance Sheet Transactions

In the normal course of business, the Company may engage in a variety of financial transactions that, under generally accepted accounting principles, either are not recorded on the balance sheet or are recorded on the balance sheet in amounts that differ from the full contract or notional amounts. These transactions involve varying elements of market, credit and liquidity risk.

Lending commitments include unfunded loan commitments and standby and commercial letters of credit. For loan commitments, the contractual amount of a commitment represents the maximum potential credit risk that could result if the entire commitment had been funded, the borrower had not performed according to the terms of the contract, and no collateral had been provided. A large majority of loan commitments and standby letters of credit expire without being funded, and accordingly, total contractual amounts are not representative of actual future credit exposure or liquidity requirements. Loan commitments and letters of credit expose the Company to credit risk in the event that the customer draws on the commitment and subsequently fails to perform under the terms of the lending agreement.

For commercial customers, loan commitments generally take the form of revolving credit arrangements. For retail customers, loan commitments generally are lines of credit secured by residential property. These instruments are not recorded on the balance sheet until funds are advanced under the commitment. Unfunded commitments to extend credit were $2.7 billion at both March 31, 2024 and December 31, 2023.

In the normal course of business, the Company and Seacoast Bank enter into agreements, or are subject to regulatory agreements that result in cash, debt and dividend restrictions. A summary of the most restrictive items follows:

Seacoast Bank may be required to maintain reserve balances with the FRB. There was no reserve requirement at March 31, 2024 or December 31, 2023.

Under FRB regulation, Seacoast Bank is limited as to the amount it may loan to its affiliates, including the Company, unless such loans are collateralized by specified obligations. At March 31, 2024, the maximum amount available for transfer from Seacoast Bank to the Company in the form of loans approximated $184.1 million, if the Company has sufficient acceptable collateral. There were no loans made to affiliates during the three months ended March 31, 2024.

Capital Resources

The Company’s equity capital at March 31, 2024 increased $9.7 million from December 31, 2023 to $2.1 billion. Changes in equity included an increase from net income of $26.0 million, partially offset by the payment of common stock dividends totaling $15.3 million and a decrease in accumulated other comprehensive income of $4.1 million.

The ratio of shareholders’ equity to period end total assets was 14.28% and 14.46% at March 31, 2024 and December 31, 2023, respectively. The ratio of tangible shareholders’ equity to tangible assets was 9.25% and 9.31% at March 31, 2024 and December 31, 2023, respectively. Changes in the value of HTM securities are not reflected in shareholders’ equity under GAAP; however, illustratively, if all HTM securities were presented at fair value, the tangible common equity ratio would have been 8.59% at March 31, 2024 and 8.68% at December 31, 2023.

Capital ratios are well above regulatory requirements for well-capitalized institutions. Management’s use of risk-based capital ratios in its analysis of the Company’s capital adequacy are not GAAP financial measures. Seacoast’s management uses these measures to assess the quality of capital and believes that investors may find it useful in their analysis of the Company. The capital measures are not necessarily comparable to similar capital measures that may be presented by other companies and Seacoast does not nor should investors consider such non-GAAP financial measures in isolation from, or as a substitute for GAAP financial information (see “Note 8 – Regulatory Capital”).

March 31, 2024	Seacoast (Consolidated)	Seacoast Bank	Minimum to be Well- Capitalized1
Total Risk-Based Capital Ratio	16.14%	15.18%	10.00%
Tier 1 Capital Ratio	14.69	13.93	8.00
Common Equity Tier 1 Ratio (CET1)	14.01	13.93	6.50
Leverage Ratio	11.06	10.49	5.00
1For subsidiary bank only.

The Company and Seacoast Bank are subject to various general regulatory policies and requirements relating to the payment of dividends, including requirements to maintain adequate capital above regulatory minimums. The appropriate federal bank regulatory authority may prohibit the payment of dividends where it has determined that the payment of dividends would be an unsafe or unsound practice. The Company is a legal entity separate and distinct from Seacoast Bank and its other subsidiaries, and the Company’s primary source of cash and liquidity, other than securities offerings and borrowings, is dividends from its bank subsidiary. Without Office of the Comptroller of the Currency (“OCC”) approval, Seacoast Bank can pay $138.7 million of dividends to the Company.

The OCC and the Federal Reserve have policies that encourage banks and bank holding companies to pay dividends from current earnings, and have the general authority to limit the dividends paid by national banks and bank holding companies, respectively, if such payment may be deemed to constitute an unsafe or unsound practice. If, in the particular circumstances, either of these federal regulators determined that the payment of dividends would constitute an unsafe or unsound banking practice, either the OCC or the Federal Reserve may, among other things, issue a cease and desist order prohibiting the payment of dividends by Seacoast Bank or us, respectively. The board of directors of a bank holding company must consider different factors to ensure that its dividend level, if any, is prudent relative to the organization’s financial position and is not based on overly optimistic earnings scenarios such as any potential events that may occur before the payment date that could affect its ability to pay, while still maintaining a strong financial position. As a general matter, the FRB has indicated that the board of directors of a bank holding company, such as Seacoast, should consult with the FRB and eliminate, defer, or significantly reduce the bank holding company’s dividends if: (i) its net income available to shareholders for the past four quarters, net of dividends previously paid during that period, is not sufficient to fully fund the dividends; (ii) its prospective rate of earnings retention is not consistent with its capital needs and overall current and prospective financial condition; or (iii) it will not meet, or is in danger of not meeting, its minimum regulatory capital adequacy ratios.

The Company has paid quarterly dividends to the holders of its common stock since the second quarter of 2021. Whether the Company continues to pay quarterly dividends and the amount of any such dividends will be at the discretion of the Company’s Board of Directors and will depend on the Company’s earnings, financial condition, results of operations, business prospects, capital requirements, regulatory restrictions, and other factors that the Board of Directors may deem relevant.

The Company has seven wholly owned trust subsidiaries that have issued trust preferred stock. Trust preferred securities from acquisitions were recorded at fair value when acquired. All trust preferred securities are guaranteed by the Company on a junior subordinated basis. The FRB’s rules permit qualified trust preferred securities and other restricted capital elements to be included under Basel III capital guidelines, with limitations, and net of goodwill and intangibles. The Company believes that its trust preferred securities qualify under these revised regulatory capital rules and believes that it can treat all its trust preferred securities as Tier 1 capital. For regulatory purposes, the trust preferred securities are added to the Company’s tangible common shareholders’ equity to calculate Tier 1 capital.

Critical Accounting Policies and Estimates

The Company’s critical accounting policies are discussed in the MD&A in Seacoast’s Annual Report on Form 10-K for the year ended December 31, 2023. Significant accounting policies and changes in accounting principles and effects of recently issued accounting pronouncements are discussed in “Note 1 – Significant Accounting Policies” in Form 10-K for the year ended December 31, 2023. Disclosures regarding the effects of new accounting pronouncements are included in “Note 1 – Basis of Presentation” in this report. There have been no changes to the Company’s critical accounting policies during 2024.

Interest Rate Sensitivity

Fluctuations in interest rates may result in changes in the fair value of the Company’s financial instruments, cash flows and net interest income. This risk is managed using simulation modeling to calculate the most likely interest rate risk utilizing estimated loan and deposit growth. The objective is to optimize the Company’s financial position, liquidity, and net interest income while limiting volatility.

Senior management regularly reviews the overall interest rate risk position and evaluates strategies to manage the risk. The Company's Asset and Liability Management Committee (“ALCO”) uses simulation analysis to monitor changes in net interest income due to changes in market interest rates. The simulation of rising, declining and flat interest rate scenarios allows management to monitor and adjust interest rate sensitivity to assess the impact of market interest rate swings. The analysis of the impact on net interest income over a twelve-month period is subjected to instantaneous changes in market rates and is monitored at least quarterly.

The following table presents the ALCO simulation model’s projected impact of a change in interest rates on the projected baseline net interest income for the 12 and 24 month periods beginning April 1, 2024, holding all balances on the balance sheet static. This change in interest rates assumes parallel shifts in the yield curve and does not take into account changes in the slope of the yield curve nor changes in balance sheet size or mix.

	% Change in Projected Baseline
	Net Interest Income
	March 31, 2024
Change in Interest Rates	1-12 months	13-24 months
+2.00%	(8.1)%	(7.6)%
+1.00%	(3.5)%	(3.1)%
Current	—%	—%
-1.00%	0.7%	—%
-2.00%	0.2%	(2.5%)

The computations of interest rate risk do not necessarily include certain actions management may undertake to manage this risk in response to changes in interest rates. Management may adjust asset or liability pricing or structure in order to manage interest rate risk through an interest rate cycle. This may include the use of investment portfolio purchases or sales or the use of derivative financial instruments, such as interest rate swaps, options, caps, floors, futures or forward contracts.

Effects of Inflation and Changing Prices

The condensed consolidated financial statements and related financial data presented herein have been prepared in accordance with U.S. GAAP, which require the measurement of financial position and operating results in terms of historical dollars, without considering changes in the relative purchasing power of money, over time, due to inflation.

Unlike most industrial companies, virtually all of the assets and liabilities of a financial institution are monetary in nature. As a result, interest rates have a more significant impact on a financial institution’s performance than the general level of inflation. However, inflation affects financial institutions by increasing their cost of goods and services purchased, as well as the cost of salaries and benefits, occupancy expense, and similar items. Inflation and related increases in interest rates generally decrease the market value of investments and loans held and may adversely affect liquidity, earnings, and shareholders’ equity. Mortgage origination and refinancing tends to slow as interest rates increase, and higher interest rates likely will reduce the Company’s earnings from such activities and the income from the sale of residential mortgage loans in the secondary market.

Item 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

See also Management’s discussion and analysis “Interest Rate Sensitivity.”

Market risk refers to potential losses arising from changes in interest rates, and other relevant market rates or prices.

Interest rate risk, defined as the exposure of net interest income and Economic Value of Equity (“EVE”) to adverse movements in interest rates, is the Company’s primary market risk, and mainly arises from the structure of the balance sheet (non-trading activities). The Company is also exposed to market risk in its investing activities. The ALCO meets regularly and is responsible for reviewing the interest rate sensitivity position of the Company and establishing policies to monitor and limit exposure to interest rate risk. The policies established by the ALCO are reviewed and approved by the Company’s board of directors. The primary goal of interest rate risk management is to control exposure to interest rate risk, within policy limits approved by the board of directors. These limits reflect the Company’s tolerance for interest rate risk over short-term and long-term horizons.

The Company also performs valuation analyses, which are used for evaluating levels of risk present in the balance sheet that might not be taken into account in the net interest income simulation analyses. Whereas net interest income simulation highlights exposures over a relatively short time horizon, valuation analysis incorporates all cash flows over the estimated remaining life of all balance sheet positions. The valuation of the balance sheet, at a point in time, is defined as the discounted present value of asset cash flows minus the discounted value of liability cash flows, the net result of which is the EVE. The sensitivity of EVE to changes in the level of interest rates is a measure of the longer-term re-pricing risks and options risks embedded in the balance sheet. In contrast to the net interest income simulation, which assumes interest rates will change over a period of time, EVE uses instantaneous changes in rates.

EVE values only the current balance sheet, and does not incorporate the growth assumptions that are used in the net interest income simulation model. As with the net interest income simulation model, assumptions about the timing and variability of balance sheet cash flows are critical in the EVE analysis. Particularly important are the assumptions driving prepayments and the expected changes in balances and pricing of the indeterminate life deposit portfolios. Core deposits are a more significant funding source for the Company, making the lives attached to core deposits more important to the accuracy of our modeling of EVE. The Company periodically reassesses its assumptions regarding the indeterminate lives of core deposits utilizing an independent third-party resource to assist.

The following table presents the projected impact of a change in interest rates on the balance sheet. This change in interest rates assumes parallel shifts in the yield curve and does not take into account changes in the slope of the yield curve.

Change in Interest Rates	% Change in
	Economic Value of
	Equity
+2.00%	(14.1)%
+1.00%	(6.0)%
Current	—%
-1.00%	4.7%
-2.00%	8.0%

While an instantaneous and severe shift in interest rates is used in this analysis, a gradual shift in interest rates would have a much more modest impact. Since EVE measures the discounted present value of cash flows over the estimated lives of instruments, the change in EVE does not directly correlate to the degree that earnings would be impacted over a shorter time horizon, i.e., the next fiscal year. Further, EVE does not consider factors such as future balance sheet growth, changes in product mix, change in yield curve relationships, and changing product spreads that could mitigate the adverse impact of changes in interest rates.

Item 4. CONTROLS AND PROCEDURES

51

Table of Contents

The Company’s management, with the participation of its chief executive officer and chief financial officer, has evaluated the effectiveness of the Company’s disclosure controls and procedures (as defined in Rule 13a-15(e) and Rule 15d-15(e) under the Exchange Act) as of March 31, 2024 and concluded that those disclosure controls and procedures are effective.

During the quarter ended March 31, 2024, there have been no changes in internal control over financial reporting that have materially affected, or are reasonably likely to materially affect, internal control over financial reporting.

Part II OTHER INFORMATION

Item 1. Legal Proceedings

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 position, or operating results or cash flows.

Item 1A. Risk Factors

In addition to the other information set forth in this report, you should consider the factors discussed in “Part I, Item 1A. Risk Factors” in our report on Form 10-K for the year ended December 31, 2023, which could materially affect our business, financial condition and prospective results. The risks described in this report, in our Form 10-K or our other SEC filings are not the only risks facing our Company. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial condition or future results. There have been no material changes with respect to the risk factors disclosed in our Annual Report on Form 10-K for the year ended December 31, 2023.

Item 2. Unregistered Sales of Equity Securities, Use of Proceeds, and Issuer Purchases of Equity Securities

During the three month period ended March 31, 2024, the Company repurchased shares of its common stock as indicated in the following table:

Period	Total Number of Shares Purchased1	Average Price Paid Per Share		Total Number of Shares Purchased as part of Public Announced Plan	Maximum Value of Shares that May Yet be Purchased Under the Plan (in thousands)
1/1/24 to 1/31/24	8,200	$	28.46	—	$	100,000
2/1/24 to 2/29/24	1,596	24.14		—	100,000
3/1/24 to 3/31/24	—	—		—	100,000
Total - 1st Quarter	9,796	$	27.67	—	$	100,000
1Includes shares that were repurchased to pay for the exercise of stock options or for income taxes owed on vesting shares of restricted stock. These shares were not purchased under the Company’s stock repurchase plan to repurchase shares.

On December 15, 2023, the Company’s Board of Directors authorized the renewal of the Company’s share repurchase program, under which the Company may, from time to time, purchase up to $100 million of its shares of outstanding common stock. Under the share repurchase program, which will expire on December 31, 2024, repurchases will be made, if at all, in accordance with applicable securities laws and may be made from time to time in the open market, by block purchase or by negotiated transactions. The amount and timing of repurchases, if any, will be based on a variety of factors, including share acquisition price, regulatory limitations, market conditions and other factors. The program does not obligate the Company to purchase any of its shares, and may be terminated or amended by the Board of Directors at any time prior to its expiration date.

No shares of the Company’s common stock were repurchased under the program during the three months ended March 31, 2024.

Accounting Policies [Abstract]

Basis of Presentation

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 months ended March 31, 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.

Earnings Per Share [Abstract]

Earnings per Share

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 months ended March 31, 2024, 327,006 options to purchase shares of the Company’s common stock were anti-dilutive. For the three months ended March 31, 2023, 161,251 options to purchase shares of the Company’s common stock were anti-dilutive.

The amortized cost and fair value of securities as of March 31, 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.

At March 31, 2024, the Company had unrealized losses of $0.5 million on U.S. Treasury securities and obligations of U.S. government agencies having a fair value of $26.0 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, on March 31, 2024, no allowance for credit losses has been recorded.

At March 31, 2024, the Company had unrealized losses of $211.1 million on commercial and residential mortgage-backed securities and collateralized mortgage obligations issued by government-sponsored entities having a fair value of $1.2 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, on March 31, 2024, no allowance for credit losses has been recorded.

At March 31, 2024, the Company had $10.5 million of unrealized losses on private label residential and commercial mortgage-backed securities and collateralized mortgage obligations having a fair value of $116.0 million. The securities have a weighted average credit support of 23%. 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 March 31, 2024, no allowance for credit losses has been recorded.

At March 31, 2024, the Company had $0.1 million of unrealized losses in floating rate collateralized loan obligations (“CLOs”) having a fair value of $107.8 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 March 31, 2024, all positions held by the Company are in AAA and AA tranches, with weighted average credit support of 41% and 28%, 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 March 31, 2024, no allowance for credit losses has been recorded.

At March 31, 2024, the Company had $1.3 million of unrealized losses on municipal securities having a fair value of $6.0 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 March 31, 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 March 31, 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 March 31, 2024 is $70.6 million 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 $8.5 million and $1.1 million, respectively, at March 31, 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 $13.5 million and $13.6 million at March 31, 2024 and December 31, 2023, respectively.

At December 31, 2023, the Company held 11,330 shares of Visa Class B stock. 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. During the three months ended March 31, 2024, the Company sold all of its Visa Class B stock, receiving net proceeds of $4.1 million.

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:

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 reduced 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 $0.2 million in interest income on nonaccrual loans during the three months ended March 31, 2024. The Company recognized $0.1 million in interest income on nonaccrual loans during the three months ended March 31, 2023.

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.

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 March 31, 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, the conflicts in the Middle East and Russia-Ukraine and the magnitude of the resulting market disruptions, and the potential impact of persistent high inflation on the economy. Outcomes in any or all of these factors 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 March 31, 2024.

In the Construction and Land Development segment, the decrease in the allowance is due to a decrease in loan balances. In this segment, the primary source of repayment is typically from proceeds of the sale, refinancing, 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 due to continued uncertainty in connection with commercial real estate valuations broadly, and the collateral values associated with the underlying loans. 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 decrease in the allowance is primarily attributed to improvement in the forecast for macroeconomic factors, partially offset by higher loan balances. Repayment is often dependent upon rental income from the successful operation of the underlying 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. The decrease in the allowance is due to an improvement in the forecast for macroeconomic factors, partially offset by an increase in loan balances. 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 due to a decrease in loan balances. 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 increase in the allowance reflects an increase in expected losses, partly offset by a decrease in loan balances.

Derivatives

Back-to-Back Swaps

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

In the second quarter of 2023, the Company 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 will assess the effectiveness on a quarterly basis. The changes in interest rates affecting the fair value of these derivative contracts are recognized in other comprehensive income. These derivative instruments are primarily for risk management purposes. For the three months ended March 31, 2024, the Company recognized gains through other comprehensive income of $4.0 million and reclassified gains of $61 thousand out of accumulated other comprehensive income into interest income.

The Company 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 values hedges utilize the portfolio layer method. The Company considers these derivatives to be highly effective at offsetting changes in interest rates and will assess the effectiveness on a quarterly basis. The changes in interest rates affecting the fair value of these derivative contracts are recognized in interest income. These derivative instruments are primarily for risk management purposes. For the three months ended March 31, 2024, the Company recognized gains through interest income of $0.4 million.

1See “Note 3 – Securities” for further detail of recurring fair value basis of individual investment categories.

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 March 31, 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.

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 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.

Allowance for credit losses at acquisition	(18,879)
Non-credit related discount	(12,361)
Total PCD loans acquired	$	123,791

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 June 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 included in the Company's income statement for the three months ended March 31, 2023 were $17.5 million.

Accounting Policies [Abstract]

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 months ended March 31, 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

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

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.

Fair Value Measurement

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.
