SEACOAST BANKING CORPORATION OF FLORIDA AND SUBSIDIARIES

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. GAAP for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, the financial statements do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Certain prior period amounts have been reclassified to conform to the current period presentation.

Operating results for the three and six months ended June 30, 2026, are not necessarily indicative of the results that may be expected for the year ending December 31, 2026, 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, 2025.

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 ACL, acquisition accounting and purchased loans, intangible assets and impairment testing, and other fair value measurements.

Issued Accounting Standards Not Yet Adopted

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

In November 2025, the FASB issued ASU 2025-08, Credit Losses (Topic 326): Purchased Loans. ASU 2025-08 requires that purchased seasoned loans be accounted for using the gross-up approach. The gross-up approach requires recognition of an ACL for the estimate of credit losses at the acquisition date. The ACL is recorded with an offsetting gross-up adjustment to the purchase price of the acquired financial asset. The standard is effective for fiscal years beginning after December 15, 2026 and for interim periods within those annual reporting periods. Early adoption is permitted. The Company is evaluating the date of adoption and the impact of the changes to its consolidated financial statements and existing disclosures.

In November 2025, the FASB issued ASU 2025-09, Derivatives and Hedging (Topic 815): Hedge Accounting Improvements. ASU 2025-09 introduces five targeted improvements to better align hedge accounting with entities’ risk management activities. The standard is effective for fiscal years beginning after December 15, 2026, and for interim periods within those annual reporting periods. Early adoption is permitted. The Company is evaluating the impact of the changes to its consolidated financial statements and existing disclosures.

In December 2025, the FASB issued ASU 2025-11, Interim Reporting (Topic 270): Narrow-Scope Improvements. ASU 2025-11 clarifies interim disclosure requirements and provides a comprehensive list of interim disclosures that are required by GAAP. The ASU also includes a disclosure principle that requires entities to disclose events since the end of the last annual reporting period that have a material impact on the entity. The standard is effective for interim reporting periods within annual reporting periods beginning after December 15, 2027. Early adoption is permitted. The Company is evaluating the impact of the changes to its consolidated financial statements and existing disclosures.

Note 2 – Earnings per Share

The Company computes EPS using the two-class method. The two-class method of computing EPS is an earnings allocation formula that determines EPS for common stock and any participating securities according to dividends declared and participation rights in undistributed earnings. The Company's Series A Non-Voting Convertible Preferred Stock is a participating security. 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 each period. Diluted EPS 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 and preferred shares using the more dilutive of either the two-class or if-converted method.

For each of the three and six month periods ended June 30, 2026, options to purchase 1,505 shares of the Company's common stock were anti-dilutive. Options to purchase shares of the Company’s common stock totaling 328,775 and 327,799, respectively, for the three and six months ended June 30, 2025, were anti-dilutive.

1Comprised of 383 individual securities.

At June 30, 2026, the Company had unrealized losses of $0.9 million on U.S. Treasury securities and obligations of U.S. government agencies having a fair value of $47.2 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

17

interest rate movements and not changes in credit quality and expects to recover the entire amortized cost basis of these securities. Therefore, at June 30, 2026, no allowance has been recorded.

At June 30, 2026, the Company had unrealized losses of $126.2 million on commercial and residential mortgage-backed securities and collateralized mortgage obligations issued by government-sponsored entities having a fair value of $2.4 billion. These securities are either explicitly or implicitly guaranteed by the U.S. government and have a long history of no credit losses. The implied government guarantee of principal and interest payments and the high credit rating of the portfolio provide a sufficient basis for the current expectation that there is no risk of loss if default were to occur. Based on the assessment of all relevant factors, the Company believes that the unrealized loss positions on these debt securities are a function of changes in investment spreads and interest rate movements and not changes in credit quality and expects to recover the entire amortized cost basis of these securities. Therefore, at June 30, 2026, no allowance has been recorded.

At June 30, 2026, the Company had $5.1 million of unrealized losses on private label residential mortgage-backed securities and collateralized mortgage obligations having a fair value of $69.5 million. The securities have weighted-average credit support of 22%. Based on the evaluation of available information relevant to collectibility, the Company believes that the unrealized loss positions on these debt securities are a function of changes in investment spreads and interest rate movements and not changes in credit quality and expects to recover the entire amortized cost basis of these securities. Therefore, at June 30, 2026, no allowance has been recorded.

At June 30, 2026, the Company had $0.9 million of unrealized losses in floating rate CLOs having a fair value of $340.3 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 June 30, 2026, all positions held by the Company are in AAA and AA tranches, with weighted-average credit support of 38% and 24%, 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 not changes in credit quality and expects to recover the entire amortized cost basis of these securities. Therefore, at June 30, 2026, no allowance has been recorded.

At June 30, 2026, the Company had $1.1 million of unrealized losses on municipal securities having a fair value of $88.1 million and $1.9 million of unrealized losses on other debt securities having a fair value of $139.0 million. These securities are highly rated issuances, 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 June 30, 2026, no allowance 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 June 30, 2026, no allowance has been recorded. The Company has the intent and ability to hold these securities until maturity.

Included in Other assets at June 30, 2026 and December 31, 2025 is $138.6 million and $135.6 million, respectively, of FHLB and Federal Reserve Bank 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 $26.8 million and $0.9 million, respectively, at June 30, 2026, and $24.5 million and $1.0 million, respectively, at December 31, 2025, is included in Other assets. Also included in Other assets are investments in CRA-qualified mutual funds carried at fair value of $13.8 million and $13.9 million at June 30, 2026 and December 31, 2025, respectively.

All interest accrued but not received for loans placed on nonaccrual is reversed against interest income. Interest subsequently received on such loans is accounted for under the cost-recovery method, whereby interest income is not recognized until the loan balance is paid down to zero. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current, and future payments are reasonably assured. The Company recognized interest income on nonaccrual loans of $0.9 million and $1.5 million during the three months ended June 30, 2026 and June 30, 2025, respectively. The Company recognized $1.8 million and $2.2 million in interest income on nonaccrual loans during the six months ended June 30, 2026 and June 30, 2025, respectively.

Loans by Risk Rating

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

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

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

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

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

The following tables present the risk rating of loans and year-to-date1 gross charge offs by year of origination as of:

Management establishes the allowance using relevant available information from both internal and external sources, relating to past events, current economic conditions, and reasonable and supportable forecasts. Forecast data is sourced from Moody’s, a

27

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 June 30, 2026 and December 31, 2025, 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 regarding monetary policy and changes in interest rates and the potential impact of those actions. Outcomes could differ from the scenarios utilized, and the Company incorporated qualitative considerations reflecting the risk of uncertain economic conditions, and for additional dimensions of risk that may not be captured in the quantitative model.

The following section discusses changes in the level of the ACL for the three months ended June 30, 2026.

The allowance increased $5.8 million, or 3.3%, during the second quarter of 2026 to $182.1 million, representing 1.38% of loans held for investment as of June 30, 2026.

In the Construction and land development segment, the decrease in allowance is primarily driven by a decrease in modeled expected losses. In this segment, the primary source of repayment is typically from proceeds of the sale or permanent financing of the underlying property; therefore, industry and collateral type and estimated collateral values are among the relevant factors in assessing expected losses.

In the CRE - owner-occupied segment, the allowance increased due to an increase in loan balances and an increase in expected losses driven by a combination of risk characteristics. Risk characteristics include, but are not limited to, collateral type, note structure and loan seasoning.

In the CRE - non-owner-occupied segment, the allowance increase is driven by an increase in loan balances. Repayment is often dependent upon rental income from the successful operation of the underlying property or from the sale of the property. Loan performance may be adversely affected by general economic conditions or conditions specific to the real estate market, including property types. Collateral type, note structure, and loan seasoning are among the risk characteristics analyzed for this segment.

The Residential real estate segment includes residential mortgage, home equity loans, and HELOCs. The decrease in the allowance is reflective of a decrease in expected losses given the portfolio’s strong credit performance, favorable asset quality trends, substantial collateral support, and progression of the integration of the acquired VBI portfolio. Risk characteristics considered for this segment include, but are not limited to, borrower FICO score, lien position, LTV 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 allowance increased in the second quarter due to an increase 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, LTV ratios, loan seasoning, and FICO scores. The increase in allowance for consumer loans was driven by an increase in loan balances.

Note 6 – Derivatives

Interest Rate Contracts

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

Cash Flow Hedges

The Company periodically enters into contracts to mitigate exposure to the variability of future cash flows due to changes in interest rates on certain segments of its variable-rate loans. During the fourth quarter of 2025, the Company entered into three interest rate caps, each with a notional amount of $100.0 million, maturing in November 2030 and December 2030. The Company considers these derivatives to be highly effective at achieving offsetting changes in cash flows attributable to changes in interest rates and has designated them as cash flow hedges. Therefore, changes in the fair value of these derivative

28

instruments are recognized in Other comprehensive income. Amortization of the premium paid on cash flow hedges is recognized in earnings over the term of the hedge in the same caption as the hedged item. For the three and six months ended June 30, 2026, the Company recognized $0.1 million and $1.4 million, respectively, through Other comprehensive income, and reclassified $0.1 million and $0.3 million, respectively, out of AOCI and into Interest Income. Over the next twelve months the Company expects to reclassify $0.6 million from AOCI into Interest Income related to these agreements.

Fair Value Hedges

The Company periodically enters into interest rate swap contracts to hedge the risk of changes in fair value of the AFS securities portfolio due to changes in SOFR. The Company considers these derivatives to be highly effective at offsetting changes in interest rates and assesses the effectiveness on a quarterly basis. The effect of changes in interest rates on the fair value of these derivative contracts is recognized in Other comprehensive income. These derivative instruments are primarily for risk management purposes. There were no securities fair value hedges during the three and six months ended June 30, 2026. For the three and six months ended June 30, 2025, the Company recognized through Other comprehensive income, net losses of $0.1 million and $0.4 million, respectively, and reclassified net losses of $0.5 million in each period out of AOCI into interest income.

The Company has entered into interest rate swap contracts to hedge the risk of changes in the fair value of a pool of residential mortgages due to changes in SOFR. These fair value hedges utilize the portfolio layer method. The Company considers these derivatives to be highly effective at offsetting changes in interest rates and assesses the effectiveness on a quarterly basis. The effect of changes in interest rates on the fair value of these derivative contracts is recognized in interest income. These derivative instruments are primarily for risk management purposes. For each of the three and six months ended June 30, 2026, the Company recognized losses through interest income of $0.1 million. For the three and six months ended June 30, 2025, the Company recognized losses of $0.1 million and $17 thousand, respectively, through interest income.

Economic Hedges

The Company enters into commitments to originate mortgage loans for which the interest rate on the loan is determined prior to funding IRLCs, forward loan sale commitments for the future delivery of these mortgage loans for sale on the secondary market, and forward TBA mortgage-backed securities, which are classified as freestanding derivatives. For the three and six months ended June 30, 2026, the Company recognized gains of $0.3 million and $0.5 million, respectively, in Mortgage banking income in the Consolidated Statements of Income related to these non-hedging derivative financial instruments.

Note 8 – Regulatory Capital

The Company is well-capitalized and at June 30, 2026, the Company and the Company’s principal banking subsidiary, Seacoast Bank, exceeded the 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.

31

Derivative financial instruments: The fair value of these derivatives is based on a discounted cash flow approach. Due to the observable nature of the inputs used in deriving the fair value of these derivative contracts, the valuation of interest rate swaps and forward TBA mortgage-backed securities is classified as Level 2. The fair values of these instruments are based upon the estimated amount the Company would receive or pay to terminate the instruments, taking into account current interest rates and, when appropriate, the current credit worthiness of the counterparties. IRLCs and forward loan sale commitment fair values are estimated based on quoted prices for similar loans in active markets. However, the value is adjusted by a factor which considers the likelihood of a loan in a lock position will ultimately close. This closing ratio is derived from internal data and is adjusted using significant accounting judgment. As such, these derivatives are classified as Level 3 measurements and the Company values these derivatives primarily using a market approach that incorporates flow mandatory market pricing, adjusted for expected pull‑through based on historical experience. For IRLCs, the weighted-average pull-through rate was 93% and 94% at June 30, 2026 and December 31, 2025, respectively, while the weighted-average current reference price was 101.33% and 101.26%, respectively. For forward loan sale commitments, the weighted-average pull-through rate was 100% at both June 30, 2026 and December 31, 2025, while the weighted-average current reference price was 101.45% and 101.12%, respectively.

Loans and OREO: Fair values of collateral-dependent real estate loans and OREO are based on recent real estate appraisals less estimated costs of sale. Evaluations may use either a single valuation approach or a combination of approaches, such as comparative sales, cost, and/or income approach. Adjustments to comparable sales may be made by an appraiser to reflect local market conditions or other economic factors and may result in changes in the fair value of an asset over time, but none were made by management. The fair values of these loans and properties are considered Level 3 in the fair value hierarchy. There were no collateral-dependent loans measured at fair value at both June 30, 2026 and December 31, 2025.

MSRs: The fair value of these servicing rights is based on an income approach. Various unobservable inputs to assumptions including expected cash flows, market discount rates, prepayment rates, servicing costs, and other factors are utilized, therefore the valuation of MSRs is classified as Level 3.

The following table presents changes in the Company's MSRs measured at fair value for the three and six months ended June 30, 2026. There was no MSR balance during the three and six months ended June 30, 2025:

	Three Months Ended		Six Months Ended

Weighted-average coupon interest rate	4.77		%	4.78		%
Weighted-average servicing fee	0.25			0.25
Weighted-average remaining maturity (in months)	348			348

The sensitivity calculations above are hypothetical changes and should not be considered to be predictive of future performance. Changes in fair value based on variations in assumptions generally cannot be extrapolated because the relationship of the change in assumption to the change in fair value may not be linear. Also, the effect of a variation in a particular assumption on the fair value is calculated without changing any other assumption, while in reality changes in one factor may result in changes in another, which may either magnify or counteract the effect of the change.

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 six months ended June 30, 2026, 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, 2025.

The short maturity of the Company’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 June 30, 2026 and December 31, 2025:

HTM 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 Level 3 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. The fair value of Level 2 loans is valued using observable market-based inputs, including quoted prices obtained from third-party pricing services based on recent market transactions and dealer quotations for comparable instruments.

34

Investments at NAV: The Company has equity investments in SBICs accounted for under the fair value practical expedient of NAV totaling $25.2 million at June 30, 2026 and $26.4 million at December 31, 2025, which are not included in the fair value hierarchy. These investments are made primarily through various SBIC funds as a strategy to provide expansion and growth opportunities to small businesses and are subject to various risks, including market, liquidity, and credit risk. SBICs are generally structured to operate for approximately 10 years and the Company’s investments are not redeemable. Distributions are received through the liquidation of the underlying assets, which is expected to occur over the next 5-10 years. Unfunded commitments related to these investments were $8.0 million at June 30, 2026 and $8.7 million at December 31, 2025.

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 Villages Bancorporation, Inc.

On October 1, 2025, the Company completed its acquisition of VBI, adding 19 branches in North Central Florida including The Villages® community.

Business Developments

Seacoast’s balanced growth strategy includes both acquisitions and organic growth initiatives. In the second half of 2025, Seacoast acquired both Heartland and VBI. These transformative transactions together added 23 branch locations, $5.3 billion in assets, and $4.2 billion in deposits, bringing leading market share and significant liquidity, further strengthening the Company’s competitive position and enhancing our capacity for sustained profitable growth. Full integration and system conversion activities for Heartland were completed in August of 2025, and for VBI, in July of 2026. The Company expects to recognize substantially all remaining merger-related costs during the third quarter of 2026. Complementing acquisitions with organic growth, in recent years Seacoast has added experienced bankers in dynamic and growing markets, leading to significant growth in new relationships. These efforts have supported core deposit generation, loan production, and expansion of client relationships across multiple product lines.

Results of Operations

Seacoast provides integrated financial services including commercial and consumer banking, wealth management, mortgage and insurance services to customers at 105 full-service branches across Florida and Georgia, and through advanced mobile and online banking solutions.

Seacoast continues to prudently manage expenses while strategically investing to support continued growth. Results during the first quarter of 2026 included a $39.5 million loss from a strategic repositioning of a portion of the AFS securities portfolio. Highlights for the second quarter of 2026 included:

Net Interest Income and Margin

Net interest income for the second quarter of 2026 totaled $180.4 million, an increase of $3.9 million, or 2%, compared to the first quarter of 2026, and an increase of $53.5 million, or 42%, compared to the second quarter of 2025. For the six months ended June 30, 2026, net interest income totaled $356.9 million, an increase of $111.5 million, or 45%, compared to the six months ended June 30, 2025. The increase compared to the first quarter of 2026 represents higher yields on the securities portfolio and loan growth, and the increases compared to the three and six month periods ended June 30, 2025 were primarily driven by higher loan and securities balances resulting from the acquisitions completed in 2025, as well as organic loan growth.

Interest income on loans in the second quarter of 2026 increased by $2.4 million, or 1%, compared to the first quarter of 2026, reflecting higher average loan balances and higher core loan yields. Securities income increased $2.5 million, or 4%, compared to the first quarter of 2026, benefiting from higher balances and the full quarter impact of the securities repositioning executed in the first quarter of 2026. Accretion on acquired loans was $8.9 million in the second quarter of 2026, $12.1 million in the first quarter of 2026, and $10.6 million in the second quarter of 2025. Accretion on acquired loans totaled $21.0 million for the six months ended June 30, 2026, compared to $18.8 million for the six months ended June 30, 2025. Interest expense on deposits increased $0.7 million, or 1%, compared to the first quarter of 2026, and increased $7.1 million, or 13%, compared to the second quarter of 2025.

Net interest margin (on an FTE basis)1 was stable at 3.83% in the second quarter of 2026 compared to the first quarter of 2026, and expanded 25 basis points from 3.58% in the second quarter of 2025. Excluding the effects of accretion on acquired loans, net interest margin expanded eight basis points to 3.65% in the second quarter of 2026 compared to 3.57% in the first quarter of 2026, and increased 36 basis points compared to 3.29% in the second quarter of 2025. The expansion in core net interest margin was driven by higher securities and loan yields and lower funding costs. The yield on loans decreased to 5.88% for the second quarter of 2026, a decrease of eight basis points from the first quarter of 2026 and decreased 10 basis points from the second quarter of 2025. Yield on loans, excluding accretion on acquired loans, was 5.61%, an increase of four basis points from the first quarter of 2026, and an increase of three basis points from the second quarter of 2025. The effect on net interest margin of accretion of purchase discounts on acquired loans was an increase of 18 basis points for the second quarter of 2026, 26 basis points in the first quarter of 2026, and 29 basis points in the second quarter of 2025. The cost of deposits was 1.53% in the second quarter of 2026, compared to 1.54% in the first quarter of 2026, and 1.80% in the second quarter of 2025. The cost of funds was 1.69% in the second quarter of 2026, compared to 1.71% in the first quarter of 2026, and 1.99% in the second quarter of 2025. Compared to the first quarter of 2026, securities yields increased 10 basis points in the second quarter of 2026 to 4.47% and increased 60 basis points from the second quarter of 2025.

42

For the six months ended June 30, 2026, net interest margin (on an FTE basis)1 increased 30 basis points to 3.83% compared to the six months ended June 30, 2025, largely driven by higher securities yields and lower deposit costs. The yield on securities was 4.42% for the six months ended June 30, 2026, compared to 3.87% for the six months ended June 30, 2025. The yield on total loans decreased from 5.94% for the six months ended June 30, 2025 to 5.92% for the six months ended June 30, 2026. The effect on net interest margin of accretion of purchase discounts on acquired loans was an increase of 22 basis points for the six months ended June 30, 2026, compared to 27 basis points for the six months ended June 30, 2025. The cost of deposits was 1.54% for the six months ended June 30, 2026, a decrease of 33 basis points compared to the six months ended June 30, 2025. The cost of funds was 1.70% for the six months ended June 30, 2026, a decrease of 32 basis points compared to the six months ended June 30, 2025.

1On an FTE basis. All yields and rates have been computed using amortized cost.

Financial Condition

Total assets as of June 30, 2026 were $21.4 billion, an increase of $0.5 billion, or 2%, from December 31, 2025.

Securities

Information related to yields, maturities, carrying values, and fair value of the Company’s securities is set forth in “Note 3 – Securities” in this report.

At June 30, 2026, the Company had $5.2 billion in AFS securities and $564.1 million in HTM securities. The Company’s total debt securities portfolio decreased $12.1 million from December 31, 2025. During the first quarter of 2026, the Company repositioned a portion of its AFS securities portfolio. Securities with an average book yield of 1.9% were sold, resulting in a pre-tax loss of approximately $39.5 million. The proceeds of approximately $277.0 million were reinvested in primarily agency mortgage-backed securities with an average taxable equivalent book yield of 4.8%.

Debt securities generally return principal and interest monthly. The modified duration of the AFS securities portfolio and the total portfolio was 5.2 and 5.3, respectively, at June 30, 2026, compared to 5.1 and 5.2, respectively, at December 31, 2025.

At June 30, 2026, AFS securities had gross unrealized losses of $136.1 million and gross unrealized gains of $24.4 million, compared to gross unrealized losses of $150.4 million and gross unrealized gains of $48.7 million at December 31, 2025.

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 $4.7 billion, or 81%, of the total portfolio at June 30, 2026.

The portfolio includes $85.3 million, with a fair value of $80.5 million, in private label residential mortgage-backed securities and collateralized mortgage obligations with weighted-average credit support of 22%. The collateral underlying these mortgage investments includes both fixed-rate and adjustable-rate residential mortgage loans.

The Company also has invested $419.9 million in floating rate CLOs. CLOs are special purpose vehicles that purchase first lien broadly syndicated corporate loans while providing support to senior tranche investors. As of June 30, 2026, all of the Company’s CLOs were in AAA/AA tranches with weighted-average credit support of 31%. 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.

50

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 June 30, 2026, 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 June 30, 2026, no allowance has been recorded.

Loan Portfolio

Loans, net of unearned income and excluding the ACL, were $13.1 billion at June 30, 2026, an increase of $517.5 million, or 4.1%, from December 31, 2025.

The Company remains committed to sound risk management practices. 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 $459 thousand, and the average commercial loan size is $1.0 million at June 30, 2026, 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 CRE lending remains well below regulatory limits (see “Loan Concentrations”).

The following tables detail loan portfolio composition at June 30, 2026 and December 31, 2025 for portfolio loans, PCD loans, and loans purchased which are not considered credit deteriorated (“Non-PCD”) as defined in “Note 4 - Loans”.

The amortized cost basis of loans included net deferred costs of $45.2 million at June 30, 2026 and $46.3 million at December 31, 2025. At June 30, 2026, the remaining fair value adjustments on acquired loans were $129.2 million, or 4.0% of the outstanding acquired loan balances, compared to $150.0 million, or 4.0% of the acquired loan balances at December 31, 2025. The net discount is accreted into interest income over the remaining lives of the related loans on a level yield basis.

Construction and land development loans increased $132.8 million, or 18%, totaling $856.7 million at June 30, 2026, compared to December 31, 2025. These loans, extended to both commercial and consumer customers, are collateralized by and for the

51

purpose of funding land development and construction projects. Repayment is from the proceeds of the sale, refinancing, or permanent financing of the property.

CRE owner occupied loans totaled $2.1 billion at June 30, 2026, an increase of $78.2 million, or 4% compared to December 31, 2025. CRE 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.

CRE non-owner occupied loans decreased $17.4 million, totaling $4.2 billion at June 30, 2026, compared to $4.3 billion at December 31, 2025. 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 $1.4 billion at June 30, 2026, with an average loan size of $2.7 million. This segment targets grocery or credit tenant-anchored shopping plazas, single credit tenant retail buildings, smaller outparcels, and other small retail units. The second-largest segment in the non-owner occupied CRE portfolio is industrial or warehouse properties, which totaled $903.4 million at June 30, 2026, with an average loan size of $3.3 million, reflecting continued demand for logistics, distribution, and manufacturing space. Non-owner occupied CRE portfolio collateralized by office properties totaled $559.9 million at June 30, 2026, with an average loan size of $1.7 million. This segment targets low to mid-rise suburban offices and is broadly diversified across many types of professional services, with limited exposure to central business districts. Other non-owner occupied CRE loans include $490.3 million collateralized by multi-family residential properties, $232.8 million collateralized by hotels or motels, and $657.4 million collateralized by other property types, including restaurants, schools and recreation centers.

Residential real estate loans increased $159.4 million, or 5%, to $3.3 billion during the six months ended June 30, 2026. Included in the balance as of June 30, 2026, were $1.4 billion of fixed rate mortgages, $1.1 billion of ARMs, and $753.4 million in home equity loans and HELOCs, compared to $1.3 billion, $1.1 billion, and $743.2 million, respectively, at December 31, 2025. Substantially all residential mortgage 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 58%, with 35% of the loans being in first lien position at June 30, 2026, unchanged from December 31, 2025.

Commercial and financial loans increased $156.3 million, or 7%, from December 31, 2025, totaling $2.5 billion at June 30, 2026. The purpose of these loans may be to provide working capital, asset acquisition or for other business purposes, and are generally supported by projected cash flows of the business, collateralized by business assets, and/or guaranteed by the business owners. The Company continues to exercise a disciplined approach to lending and is benefiting from the investments made in recent years to attract talent from large regional banks across its markets. This talent is onboarding significant new relationships, resulting in increased loan production.

The Company also provides consumer loans, which include installment loans, auto loans, marine loans, and other consumer loans, which increased $8.1 million, or 4%, to total $193.7 million at June 30, 2026, compared to $185.6 million at December 31, 2025.

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 CRE loan relationships greater than $10 million totaled $4.1 billion, representing 31% of the total portfolio at June 30, 2026, compared to $3.5 billion, or 28%, at December 31, 2025. The Company’s ten largest commercial and CRE funded and unfunded relationships at June 30, 2026 aggregated to $617.3 million, of which $528.7 million was funded, compared to $607.4 million at December 31, 2025, of which $518.4 million was funded.

Concentrations in construction and land development loans and CRE loans are maintained well below regulatory guidelines. Construction and land development and CRE loan concentrations as a percentage of subsidiary bank total risk-based capital were 40% and 230%, respectively, at June 30, 2026, compared to 34% and 227%, respectively, at December 31, 2025. Regulatory guidance suggests limits of 100% and 300%, respectively. On a consolidated basis, construction and land development and CRE loans represent 37% and 216%, respectively, of total consolidated risk-based capital as of June 30, 2026, compared to 32% and 216%, respectively, at December 31, 2025. 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

52

of the sale, refinancing, or permanent financing of the property. Loans to 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, TBMs, OREO and Credit Quality

NPAs at June 30, 2026 totaled $90.0 million, and were comprised of $86.5 million of nonaccrual loans and $3.5 million of OREO. Overall, NPAs increased $13.8 million, or 18%, from $76.3 million as of December 31, 2025. NPAs to total assets at June 30, 2026 increased to 0.42% from 0.37% at December 31, 2025.

Compared to December 31, 2025, nonaccrual loans increased $14.5 million to $86.5 million, and remain low as a percentage of total loans, at 0.66% at June 30, 2026. Approximately 83% of nonaccrual loans at June 30, 2026 were secured with real estate. A significant portion of nonaccrual loans have collateral values well in excess of balances outstanding, and therefore, no loss is expected.

The tables below set forth details related to 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 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 quarterly, as described above.

In certain circumstances, the Company provides modifications of loans to borrowers experiencing financial difficulty, which the Company refers to as TBMs. Loans that were modified as TBMs during the three and six months ended June 30, 2026 are described in “Note 4 - Loans”.

ACL on Loans

53

Management establishes the allowance using relevant available information from both internal and external sources, relating to past events, current economic 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.

The Company recorded provision expense of $9.0 million and $9.8 million, respectively, for the three and six months ended June 30, 2026, compared to $4.4 million and $13.6 million, respectively, for the three and six months ended June 30, 2025. The Company recorded net charge-offs of $3.2 million and $6.5 million, respectively, in the three and six months ended June 30, 2026, compared to $2.5 million and $9.5 million, respectively, for the three and six months ended June 30, 2025.

The ratio of ACL to total loans was 1.38% at June 30, 2026, 1.42% at December 31, 2025, and 1.34% at June 30, 2025.

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 $429.9 million at June 30, 2026, compared to $388.5 million at December 31, 2025.

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. Uninsured deposits represented approximately 36% of total deposits at June 30, 2026 compared to 37% at December 31, 2025. 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 32% of total deposits at June 30, 2026. The Company has liquidity sources as discussed below, including cash and lines of credit with the FRB and FHLB, that represent 158% of uninsured deposits, and 181% of uninsured and uncollateralized deposits.

In addition to $429.9 million in cash and cash equivalents at June 30, 2026, the Company had $9.2 billion in available borrowing capacity, including $5.0 billion in available collateralized lines of credit, $3.8 billion of unpledged debt securities available as collateral for potential additional borrowings, and available unsecured lines of credit of $348.0 million. The Company may also access funding by acquiring brokered deposits. Brokered deposits at June 30, 2026 totaled $611.6 million, compared to $120.9 million at December 31, 2025.

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 AFS, 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 second quarter of 2026, Seacoast Bank distributed $55.3 million to the Company. At June 30, 2026, the Company had cash and cash equivalents at the parent of approximately $102.1 million, compared to $98.1 million at December 31, 2025.

The Company benefits from a diverse and granular deposit base that serves as a significant source of strength. Total deposits increased $536.0 million, or 7% annualized, to $16.8 billion at June 30, 2026, when compared to December 31, 2025. Excluding brokered deposits, organic year to date deposit growth was 1% annualized.

Customer repurchase agreements totaled $373.1 million at June 30, 2026, decreasing $15.9 million, or 4%, from December 31, 2025. Repurchase agreements are offered by Seacoast to select customers who wish to sweep excess balances on a daily basis for investment purposes.

At June 30, 2026 and December 31, 2025, long-term debt included $72.9 million and $72.8 million, respectively, related to trust preferred securities issued by trusts organized or acquired by the Company. At June 30, 2026, the average interest rate in effect on our outstanding subordinated debt related to trust preferred securities was 5.68%, compared to 5.77% at December 31, 2025. All trust preferred securities are guaranteed by the Company on a junior subordinated basis. Other long-term debt at June 30, 2026 totaled $40.0 million and included financing obligations associated with branch properties and subordinated debt acquired through a bank acquisition.

FHLB advances totaled $835.0 million at June 30, 2026 with a weighted-average interest rate of 3.80%, compared to advances outstanding of $835.0 million at December 31, 2025 with a weighted-average interest rate of 3.82%. FHLB advances provide a flexible and collateralized source of wholesale funding.

Off-Balance Sheet Transactions

In the normal course of business, the Company may engage in a variety of financial transactions that, under GAAP, 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 $3.5 billion at both June 30, 2026 and December 31, 2025.

55

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 June 30, 2026 or December 31, 2025.

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 June 30, 2026, the maximum amount available for transfer from Seacoast Bank to the Company in the form of loans approximated $277.1 million, if the Company has sufficient acceptable collateral. There were no loans made to affiliates during the six months ended June 30, 2026.

Capital Resources

The Company’s equity capital at June 30, 2026 increased $18.1 million, or 1%, from December 31, 2025 to $2.7 billion. Changes in equity included increases from net income, partially offset by the issuance of cash dividends on common and preferred stock and the repurchase of common stock.

In conjunction with the acquisition of VBI on October 1, 2025, the Company issued non-voting convertible preferred stock, and each 1/1,000th of a share of preferred stock is convertible into one share of Seacoast common stock, subject to certain restrictions. Holders of preferred stock are entitled to receive ratable dividends when dividends are concurrently declared and payable on the shares of Seacoast common stock. See "Note 11 – Business Combinations," for further detail. The convertible preferred stock at June 30, 2026 totaled $343.1 million.

Activity in shareholders’ equity for the six months ended June 30, 2026 and 2025 follows:

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”).

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

56

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 OCC approval, Seacoast Bank can pay $90.2 million of dividends to the Company.

The OCC and the Federal Reserve have policies that encourage banks and BHCs to pay dividends from current earnings, and have the general authority to limit the dividends paid by national banks and BHCs, 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 BHC 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 BHC, such as Seacoast, should consult with the FRB and eliminate, defer, or significantly reduce the BHC’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 Company believes its trust preferred securities qualify as Tier 1 capital under FRB’s regulatory capital rules. A phase out period begins in June 2027, at which time the trust preferred securities will transition to Tier 2 capital over a three year period.

On March 19, 2026, U.S. banking regulators requested comments on three proposals to modernize the regulatory capital framework for banks of all sizes. The proposals are intended to streamline capital requirements and better align regulatory capital with risk while maintaining the safety and soundness of the banking system. The comment period for all three proposals ended on June 18, 2026. The Company continues to evaluate the potential impact of the proposals and monitor regulatory developments, including any final rulemaking and implementation timelines.

Critical Accounting Policies and Estimates

The Company’s critical accounting policies are discussed in the Management’s Discussion and Analysis of Financial Condition and Results of Operations in Seacoast’s Annual Report on Form 10-K for the year ended December 31, 2025. Significant accounting policies are discussed in “Note 1 – Significant Accounting Policies” in Form 10-K for the year ended December 31, 2025. 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 2026.

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. 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 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 balance sheet exposures to assess the impact of market interest rate swings. The analysis of the impact on net interest income 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 net interest income for the 12 and 24 month periods beginning July 1, 2026, holding all balances on the balance sheet static. It is important to note that the results in the table below assume parallel shifts in the yield curve and do not take into account changes in the yield curve slope nor changes in balance sheet size or mix.

57

	% Change in Projected Baseline
	Net Interest Income
	June 30, 2026
Change in Interest Rates	1-12 months	13-24 months
+3.00%	(2.2)%	3.1%
+2.00%	(0.6)%	3.0%
+1.00%	—%	1.9%
Current	—%	—%
-1.00%	1.5%	(0.6%)
-2.00%	2.9%	(2.0%)
-3.00%	4.3%	(3.6%)

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 economic 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 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. A decline in interest rates would generally have the opposite impact.

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 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. Similar to net interest income simulation, EVE uses instantaneous changes in rates. Results of both net interest income simulation and EVE analyses are sensitive to changes in key modeling assumptions.

58

EVE values only the current balance sheet and does not incorporate the reinvestment 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 maturity deposit portfolios. Stable deposits are a more significant funding source for the Company, making the estimated lives attached to stable deposits more important to the accuracy of our EVE modeling. 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
+3.00%	(16.3)%
+2.00%	(9.9)%
+1.00%	(4.3)%
Current	—%
-1.00%	3.9%
-2.00%	6.6%
-3.00%	7.2%

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

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 June 30, 2026 and concluded that those disclosure controls and procedures are effective.

During the quarter ended June 30, 2026, 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, 2025, 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, 2025.

Total - 2nd Quarter	92,125	$	30.60	751,680	$	117,000
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 19, 2025, 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 $150 million of its shares of outstanding common stock. Under the share repurchase program, which will expire on December 31, 2026, 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.

Accounting Policies [Abstract]

Basis of Presentation

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. GAAP for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, the financial statements do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Certain prior period amounts have been reclassified to conform to the current period presentation.

Operating results for the three and six months ended June 30, 2026, are not necessarily indicative of the results that may be expected for the year ending December 31, 2026, 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, 2025.

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 ACL, acquisition accounting and purchased loans, intangible assets and impairment testing, and other fair value measurements.

Issued Accounting Standards Not Yet Adopted

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

In November 2025, the FASB issued ASU 2025-08, Credit Losses (Topic 326): Purchased Loans. ASU 2025-08 requires that purchased seasoned loans be accounted for using the gross-up approach. The gross-up approach requires recognition of an ACL for the estimate of credit losses at the acquisition date. The ACL is recorded with an offsetting gross-up adjustment to the purchase price of the acquired financial asset. The standard is effective for fiscal years beginning after December 15, 2026 and for interim periods within those annual reporting periods. Early adoption is permitted. The Company is evaluating the date of adoption and the impact of the changes to its consolidated financial statements and existing disclosures.

In November 2025, the FASB issued ASU 2025-09, Derivatives and Hedging (Topic 815): Hedge Accounting Improvements. ASU 2025-09 introduces five targeted improvements to better align hedge accounting with entities’ risk management activities. The standard is effective for fiscal years beginning after December 15, 2026, and for interim periods within those annual reporting periods. Early adoption is permitted. The Company is evaluating the impact of the changes to its consolidated financial statements and existing disclosures.

In December 2025, the FASB issued ASU 2025-11, Interim Reporting (Topic 270): Narrow-Scope Improvements. ASU 2025-11 clarifies interim disclosure requirements and provides a comprehensive list of interim disclosures that are required by GAAP. The ASU also includes a disclosure principle that requires entities to disclose events since the end of the last annual reporting period that have a material impact on the entity. The standard is effective for interim reporting periods within annual reporting periods beginning after December 15, 2027. Early adoption is permitted. The Company is evaluating the impact of the changes to its consolidated financial statements and existing disclosures.

Earnings Per Share [Abstract]

Earnings per Share

Note 2 – Earnings per Share

The Company computes EPS using the two-class method. The two-class method of computing EPS is an earnings allocation formula that determines EPS for common stock and any participating securities according to dividends declared and participation rights in undistributed earnings. The Company's Series A Non-Voting Convertible Preferred Stock is a participating security. 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 each period. Diluted EPS 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 and preferred shares using the more dilutive of either the two-class or if-converted method.

For each of the three and six month periods ended June 30, 2026, options to purchase 1,505 shares of the Company's common stock were anti-dilutive. Options to purchase shares of the Company’s common stock totaling 328,775 and 327,799, respectively, for the three and six months ended June 30, 2025, were anti-dilutive.

1Comprised of 383 individual securities.

At June 30, 2026, the Company had unrealized losses of $0.9 million on U.S. Treasury securities and obligations of U.S. government agencies having a fair value of $47.2 million. These securities are either explicitly or implicitly guaranteed by the full faith and credit of the U.S. government. The Company does not expect individual securities issued by the U.S. Treasury, a U.S. agency, or a sponsored U.S. agency to incur future losses of principal. Based on the assessment of all relevant factors, the Company believes that the unrealized loss positions on these debt securities are a function of changes in investment spreads and

interest rate movements and not changes in credit quality and expects to recover the entire amortized cost basis of these securities. Therefore, at June 30, 2026, no allowance has been recorded.

At June 30, 2026, the Company had unrealized losses of $126.2 million on commercial and residential mortgage-backed securities and collateralized mortgage obligations issued by government-sponsored entities having a fair value of $2.4 billion. These securities are either explicitly or implicitly guaranteed by the U.S. government and have a long history of no credit losses. The implied government guarantee of principal and interest payments and the high credit rating of the portfolio provide a sufficient basis for the current expectation that there is no risk of loss if default were to occur. Based on the assessment of all relevant factors, the Company believes that the unrealized loss positions on these debt securities are a function of changes in investment spreads and interest rate movements and not changes in credit quality and expects to recover the entire amortized cost basis of these securities. Therefore, at June 30, 2026, no allowance has been recorded.

At June 30, 2026, the Company had $5.1 million of unrealized losses on private label residential mortgage-backed securities and collateralized mortgage obligations having a fair value of $69.5 million. The securities have weighted-average credit support of 22%. Based on the evaluation of available information relevant to collectibility, the Company believes that the unrealized loss positions on these debt securities are a function of changes in investment spreads and interest rate movements and not changes in credit quality and expects to recover the entire amortized cost basis of these securities. Therefore, at June 30, 2026, no allowance has been recorded.

At June 30, 2026, the Company had $0.9 million of unrealized losses in floating rate CLOs having a fair value of $340.3 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 June 30, 2026, all positions held by the Company are in AAA and AA tranches, with weighted-average credit support of 38% and 24%, 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 not changes in credit quality and expects to recover the entire amortized cost basis of these securities. Therefore, at June 30, 2026, no allowance has been recorded.

At June 30, 2026, the Company had $1.1 million of unrealized losses on municipal securities having a fair value of $88.1 million and $1.9 million of unrealized losses on other debt securities having a fair value of $139.0 million. These securities are highly rated issuances, 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 June 30, 2026, no allowance 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 June 30, 2026, no allowance has been recorded. The Company has the intent and ability to hold these securities until maturity.

Included in Other assets at June 30, 2026 and December 31, 2025 is $138.6 million and $135.6 million, respectively, of FHLB and Federal Reserve Bank 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 $26.8 million and $0.9 million, respectively, at June 30, 2026, and $24.5 million and $1.0 million, respectively, at December 31, 2025, is included in Other assets. Also included in Other assets are investments in CRA-qualified mutual funds carried at fair value of $13.8 million and $13.9 million at June 30, 2026 and December 31, 2025, respectively.

All interest accrued but not received for loans placed on nonaccrual is reversed against interest income. Interest subsequently received on such loans is accounted for under the cost-recovery method, whereby interest income is not recognized until the loan balance is paid down to zero. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current, and future payments are reasonably assured. The Company recognized interest income on nonaccrual loans of $0.9 million and $1.5 million during the three months ended June 30, 2026 and June 30, 2025, respectively. The Company recognized $1.8 million and $2.2 million in interest income on nonaccrual loans during the six months ended June 30, 2026 and June 30, 2025, respectively.

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 economic conditions, and reasonable and supportable forecasts. Forecast data is sourced from 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 June 30, 2026 and December 31, 2025, 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 regarding monetary policy and changes in interest rates and the potential impact of those actions. Outcomes could differ from the scenarios utilized, and the Company incorporated qualitative considerations reflecting the risk of uncertain economic conditions, and for additional dimensions of risk that may not be captured in the quantitative model.

The following section discusses changes in the level of the ACL for the three months ended June 30, 2026.

The allowance increased $5.8 million, or 3.3%, during the second quarter of 2026 to $182.1 million, representing 1.38% of loans held for investment as of June 30, 2026.

In the Construction and land development segment, the decrease in allowance is primarily driven by a decrease in modeled expected losses. In this segment, the primary source of repayment is typically from proceeds of the sale or permanent financing of the underlying property; therefore, industry and collateral type and estimated collateral values are among the relevant factors in assessing expected losses.

In the CRE - owner-occupied segment, the allowance increased due to an increase in loan balances and an increase in expected losses driven by a combination of risk characteristics. Risk characteristics include, but are not limited to, collateral type, note structure and loan seasoning.

In the CRE - non-owner-occupied segment, the allowance increase is driven by an increase in loan balances. Repayment is often dependent upon rental income from the successful operation of the underlying property or from the sale of the property. Loan performance may be adversely affected by general economic conditions or conditions specific to the real estate market, including property types. Collateral type, note structure, and loan seasoning are among the risk characteristics analyzed for this segment.

The Residential real estate segment includes residential mortgage, home equity loans, and HELOCs. The decrease in the allowance is reflective of a decrease in expected losses given the portfolio’s strong credit performance, favorable asset quality trends, substantial collateral support, and progression of the integration of the acquired VBI portfolio. Risk characteristics considered for this segment include, but are not limited to, borrower FICO score, lien position, LTV 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 allowance increased in the second quarter due to an increase 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, LTV ratios, loan seasoning, and FICO scores. The increase in allowance for consumer loans was driven by an increase in loan balances.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivatives

Note 6 – Derivatives

Interest Rate Contracts

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

Cash Flow Hedges

The Company periodically enters into contracts to mitigate exposure to the variability of future cash flows due to changes in interest rates on certain segments of its variable-rate loans. During the fourth quarter of 2025, the Company entered into three interest rate caps, each with a notional amount of $100.0 million, maturing in November 2030 and December 2030. The Company considers these derivatives to be highly effective at achieving offsetting changes in cash flows attributable to changes in interest rates and has designated them as cash flow hedges. Therefore, changes in the fair value of these derivative

instruments are recognized in Other comprehensive income. Amortization of the premium paid on cash flow hedges is recognized in earnings over the term of the hedge in the same caption as the hedged item. For the three and six months ended June 30, 2026, the Company recognized $0.1 million and $1.4 million, respectively, through Other comprehensive income, and reclassified $0.1 million and $0.3 million, respectively, out of AOCI and into Interest Income. Over the next twelve months the Company expects to reclassify $0.6 million from AOCI into Interest Income related to these agreements.

Fair Value Hedges

The Company periodically enters into interest rate swap contracts to hedge the risk of changes in fair value of the AFS securities portfolio due to changes in SOFR. The Company considers these derivatives to be highly effective at offsetting changes in interest rates and assesses the effectiveness on a quarterly basis. The effect of changes in interest rates on the fair value of these derivative contracts is recognized in Other comprehensive income. These derivative instruments are primarily for risk management purposes. There were no securities fair value hedges during the three and six months ended June 30, 2026. For the three and six months ended June 30, 2025, the Company recognized through Other comprehensive income, net losses of $0.1 million and $0.4 million, respectively, and reclassified net losses of $0.5 million in each period out of AOCI into interest income.

The Company has entered into interest rate swap contracts to hedge the risk of changes in the fair value of a pool of residential mortgages due to changes in SOFR. These fair value hedges utilize the portfolio layer method. The Company considers these derivatives to be highly effective at offsetting changes in interest rates and assesses the effectiveness on a quarterly basis. The effect of changes in interest rates on the fair value of these derivative contracts is recognized in interest income. These derivative instruments are primarily for risk management purposes. For each of the three and six months ended June 30, 2026, the Company recognized losses through interest income of $0.1 million. For the three and six months ended June 30, 2025, the Company recognized losses of $0.1 million and $17 thousand, respectively, through interest income.

Economic Hedges

The Company enters into commitments to originate mortgage loans for which the interest rate on the loan is determined prior to funding IRLCs, forward loan sale commitments for the future delivery of these mortgage loans for sale on the secondary market, and forward TBA mortgage-backed securities, which are classified as freestanding derivatives. For the three and six months ended June 30, 2026, the Company recognized gains of $0.3 million and $0.5 million, respectively, in Mortgage banking income in the Consolidated Statements of Income related to these non-hedging derivative financial instruments.

1See “Note 3 – Securities” for further detail of fair value of individual investment categories.
2Recurring fair value basis determined using observable market data for level 2 inputs. Level 3 inputs utilize a market approach that incorporates a pull-through rate assumption.
3Fair value is measured on a nonrecurring basis.
4Investment 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 with fair value adjustments recognized in earnings.
5Recurring fair value basis determined using unobservable market data. Refer to “Note 8 - Goodwill and Acquired Intangible Assets” in the Company’s Annual Report on Form 10-K for the year ended December 31, 2025 for additional details on assumptions utilized.

Derivative financial instruments: The fair value of these derivatives is based on a discounted cash flow approach. Due to the observable nature of the inputs used in deriving the fair value of these derivative contracts, the valuation of interest rate swaps and forward TBA mortgage-backed securities is classified as Level 2. The fair values of these instruments are based upon the estimated amount the Company would receive or pay to terminate the instruments, taking into account current interest rates and, when appropriate, the current credit worthiness of the counterparties. IRLCs and forward loan sale commitment fair values are estimated based on quoted prices for similar loans in active markets. However, the value is adjusted by a factor which considers the likelihood of a loan in a lock position will ultimately close. This closing ratio is derived from internal data and is adjusted using significant accounting judgment. As such, these derivatives are classified as Level 3 measurements and the Company values these derivatives primarily using a market approach that incorporates flow mandatory market pricing, adjusted for expected pull‑through based on historical experience. For IRLCs, the weighted-average pull-through rate was 93% and 94% at June 30, 2026 and December 31, 2025, respectively, while the weighted-average current reference price was 101.33% and 101.26%, respectively. For forward loan sale commitments, the weighted-average pull-through rate was 100% at both June 30, 2026 and December 31, 2025, while the weighted-average current reference price was 101.45% and 101.12%, respectively.

Loans and OREO: Fair values of collateral-dependent real estate loans and OREO are based on recent real estate appraisals less estimated costs of sale. Evaluations may use either a single valuation approach or a combination of approaches, such as comparative sales, cost, and/or income approach. Adjustments to comparable sales may be made by an appraiser to reflect local market conditions or other economic factors and may result in changes in the fair value of an asset over time, but none were made by management. The fair values of these loans and properties are considered Level 3 in the fair value hierarchy. There were no collateral-dependent loans measured at fair value at both June 30, 2026 and December 31, 2025.

MSRs: The fair value of these servicing rights is based on an income approach. Various unobservable inputs to assumptions including expected cash flows, market discount rates, prepayment rates, servicing costs, and other factors are utilized, therefore the valuation of MSRs is classified as Level 3.

The following table presents changes in the Company's MSRs measured at fair value for the three and six months ended June 30, 2026. There was no MSR balance during the three and six months ended June 30, 2025:

	Three Months Ended		Six Months Ended

Carrying value at end of period	$	26,784	$	26,784

The following table presents data and key economic assumptions, as well as the valuation's sensitivity to interest rate fluctuations, related to the Company’s MSRs as of:

(In thousands)	June 30, 2026			December 31, 2025

Weighted-average coupon interest rate	4.77		%	4.78		%
Weighted-average servicing fee	0.25			0.25
Weighted-average remaining maturity (in months)	348			348

The sensitivity calculations above are hypothetical changes and should not be considered to be predictive of future performance. Changes in fair value based on variations in assumptions generally cannot be extrapolated because the relationship of the change in assumption to the change in fair value may not be linear. Also, the effect of a variation in a particular assumption on the fair value is calculated without changing any other assumption, while in reality changes in one factor may result in changes in another, which may either magnify or counteract the effect of the change.

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 six months ended June 30, 2026, 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, 2025.

The short maturity of the Company’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 June 30, 2026 and December 31, 2025:

HTM 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 Level 3 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. The fair value of Level 2 loans is valued using observable market-based inputs, including quoted prices obtained from third-party pricing services based on recent market transactions and dealer quotations for comparable instruments.

Investments at NAV: The Company has equity investments in SBICs accounted for under the fair value practical expedient of NAV totaling $25.2 million at June 30, 2026 and $26.4 million at December 31, 2025, which are not included in the fair value hierarchy. These investments are made primarily through various SBIC funds as a strategy to provide expansion and growth opportunities to small businesses and are subject to various risks, including market, liquidity, and credit risk. SBICs are generally structured to operate for approximately 10 years and the Company’s investments are not redeemable. Distributions are received through the liquidation of the underlying assets, which is expected to occur over the next 5-10 years. Unfunded commitments related to these investments were $8.0 million at June 30, 2026 and $8.7 million at December 31, 2025.

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.

The acquisition of VBI was accounted for under the acquisition method of accounting in accordance with ASC Topic 805, Business Combinations. The Company recognized goodwill of $280.4 million for this acquisition that is nondeductible for tax purposes. Determining fair values of assets and liabilities, especially the loan portfolio, CDI, and deferred taxes, is a complicated process involving significant judgment regarding methods and assumptions used to calculate estimated fair values.

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. GAAP for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, the financial statements do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Certain prior period amounts have been reclassified to conform to the current period presentation.

Operating results for the three and six months ended June 30, 2026, are not necessarily indicative of the results that may be expected for the year ending December 31, 2026, 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, 2025.

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 ACL, acquisition accounting and purchased loans, intangible assets and impairment testing, and other fair value measurements.

Issued Accounting Standards Not Yet Adopted

Issued Accounting Standards Not Yet Adopted

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

In November 2025, the FASB issued ASU 2025-08, Credit Losses (Topic 326): Purchased Loans. ASU 2025-08 requires that purchased seasoned loans be accounted for using the gross-up approach. The gross-up approach requires recognition of an ACL for the estimate of credit losses at the acquisition date. The ACL is recorded with an offsetting gross-up adjustment to the purchase price of the acquired financial asset. The standard is effective for fiscal years beginning after December 15, 2026 and for interim periods within those annual reporting periods. Early adoption is permitted. The Company is evaluating the date of adoption and the impact of the changes to its consolidated financial statements and existing disclosures.

In November 2025, the FASB issued ASU 2025-09, Derivatives and Hedging (Topic 815): Hedge Accounting Improvements. ASU 2025-09 introduces five targeted improvements to better align hedge accounting with entities’ risk management activities. The standard is effective for fiscal years beginning after December 15, 2026, and for interim periods within those annual reporting periods. Early adoption is permitted. The Company is evaluating the impact of the changes to its consolidated financial statements and existing disclosures.

In December 2025, the FASB issued ASU 2025-11, Interim Reporting (Topic 270): Narrow-Scope Improvements. ASU 2025-11 clarifies interim disclosure requirements and provides a comprehensive list of interim disclosures that are required by GAAP. The ASU also includes a disclosure principle that requires entities to disclose events since the end of the last annual reporting period that have a material impact on the entity. The standard is effective for interim reporting periods within annual reporting periods beginning after December 15, 2027. Early adoption is permitted. The Company is evaluating the impact of the changes to its consolidated financial statements and existing disclosures.

Fair Value Measurement

HTM 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 Level 3 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. The fair value of Level 2 loans is valued using observable market-based inputs, including quoted prices obtained from third-party pricing services based on recent market transactions and dealer quotations for comparable instruments.

Investments at NAV: The Company has equity investments in SBICs accounted for under the fair value practical expedient of NAV totaling $25.2 million at June 30, 2026 and $26.4 million at December 31, 2025, which are not included in the fair value hierarchy. These investments are made primarily through various SBIC funds as a strategy to provide expansion and growth opportunities to small businesses and are subject to various risks, including market, liquidity, and credit risk. SBICs are generally structured to operate for approximately 10 years and the Company’s investments are not redeemable. Distributions are received through the liquidation of the underlying assets, which is expected to occur over the next 5-10 years. Unfunded commitments related to these investments were $8.0 million at June 30, 2026 and $8.7 million at December 31, 2025.

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.
