The strong net interest margin expansion in the fourth quarter evidenced the solid, granular core deposit franchise that we have built over many decades through our relationship-focused banking model. With accelerating business momentum and tailwinds from fixed rate asset repricing, we remain focused on profitability improvement and growth in the year ahead."

Shaffer added, "We advanced several key initiatives this year including the expansion of our commercial lending team and treasury deposit products that will support the next phase of growth for Seacoast. With a tangible common equity ratio of 9.6% and a loan to deposit ratio of 84%, we have a tremendous opportunity ahead to serve clients in our economically vibrant footprint."

Shaffer concluded, "The Seacoast team remains unwavering to our core tenets of maintaining a fortress balance sheet and building one of the best, granular customer deposit franchises in the country."

For the year endedDecember 31, 2024, net interest income was $432.0 million, a decrease of $56.3 million, or 12%, compared to the year endedDecember 31, 2023. The increase in the fourth quarter of 2024 was largely driven by a 26 basis point decline in the cost of deposits. Included in loan interest income was accretion on acquired loans of $11.7 million in the fourth quarter of 2024, $9.2 million in the third quarter of 2024, and $11.3 million in the fourth quarter of 2023. For the year ended December 31, 2024, accretion on acquired loans totaled $41.7 million, compared to $56.7 million for the year ended December 31, 2023.

Lower interest expense on deposits reflects the impact of recent cuts to the Federal Funds rate.

•Noninterest income totaled $17.1 million in the fourth quarter of 2024, a decrease of $6.6 million, or 28%, compared to the prior quarter, and a decrease of $0.3 million, or 2%, compared to the prior year quarter.

efficiency ratio1 was 56.07% in the fourth quarter of 2024, compared to 59.84% in the third quarter of 2024 and 60.32% in the prior year quarter. The efficiency ratio for the year ended December 31, 2024 was 60.63% compared to 63.86% for the year ended December 31, 2023. The adjusted efficiency ratio1 for the year ended December 31, 2024 was 59.22% compared to 57.35% for the year ended December 31, 2023. The Company continues to remain keenly focused on disciplined expense control, while making investments for growth.

Balance Sheet

•At December 31, 2024, the Company had total assets of $15.2 billion and totalshareholders' equity of $2.2 billion. Book value per share was $25.51 as of December 31, 2024, compared to $25.68 as of September 30, 2024, and $24.84 as of December 31, 2023. Tangible book value per share was $16.12 as of December 31, 2024, compared to $16.20 as of September 30, 2024, and $15.08 as of December 31, 2023. The decline in the value of the available-for-sale securities portfolio driven by rising longer term interest rates negatively impacted tangible book value per share by $0.38 during the fourth quarter of 2024.

•Debt securities totaled $2.9 billion as of December 31, 2024, an increase of $55.6 million compared to September 30, 2024. Debt securities include approximately $2.2 billion in securities classified as available-for-sale and recorded at fair value. The unrealized loss on these securities is fully reflected in the value presented on the balance sheet. The portfolio also includes $635.2 million in securities classified as held-to-maturity with a fair value of $507.6 million. Held-to-maturity securities consist solely of mortgage-backed securities and collateralized mortgage obligations guaranteed by U.S. government agencies, 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 and has the intent and ability to hold these investments to maturity.

•Loans increased $94.7 million, or 3.7% annualized, totaling $10.3 billion as of December 31, 2024. Loan originations increased 37% to $902.6 million in the fourth quarter of 2024, compared to $657.9 million in the third quarter of 2024. Gross production during the fourth quarter of 2024 was offset by elevated payoffs, the sale of two nonperforming commercial real estate loans totaling $19.0 million in aggregate, and the transfer to held-for-sale of $20.0 million in consumer loans previously acquired through bank acquisitions (the “consumer fintech loans”). 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.

•Loan pipelines (loans in underwriting and approval or approved and not yet closed) totaled $693.3 million as of December 31, 2024, compared to $831.1 million at September 30, 2024 and $393.0 million at December 31, 2023.

•Commercial pipelines were $605.4 million as of December 31, 2024, compared to $744.5 million at September 30, 2024, and $306.5 million at December 31, 2023.

•SBA pipelines were $28.8 million as of December 31, 2024, compared to $28.9 million at September 30, 2024, and $20.6 million at December 31, 2023.

•Residential saleable pipelines were $6.7 million as of December 31, 2024, compared to $11.2 million at September 30, 2024, and $2.7 million at December 31, 2023. Retained residential pipelines were $35.1 million as of December 31, 2024, compared to $21.9 million at September 30, 2024, and $44.4 million at December 31, 2023.

•Consumer pipelines were $17.4 million as of December 31, 2024, compared to $24.4 million at September 30, 2024 and $18.7 million at December 31, 2023.

•Total deposits were $12.2 billion as of December 31, 2024, near flatwhen compared to September 30, 2024.

•At December 31, 2024, customer transaction account balances represented 50% of total deposits.

•The Company benefits from a granular deposit franchise, with the top ten depositors representing approximately 4% of total deposits.

1Non-GAAP measure, see “Explanation of Certain Unaudited Non-GAAP Financial Measures" for more information and for a reconciliation to GAAP.

•Average deposits per banking center were $159 million at December 31, 2024, compared to $153 million atDecember 31, 2023.

•Uninsured deposits represented only 36% of overall deposit accounts as of December 31, 2024. 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 30% of total deposits. The Company has liquidity sources including cash and lines of credit with the Federal Reserve and Federal Home Loan Bank that represent 138% of uninsured deposits, and 167% of uninsured and uncollateralized deposits.

•Consumer deposits represent 41% of overall deposit funding with an average consumer customer balance of $25 thousand. Commercial deposits represent 59% of overall deposit funding with an average business customer balance of $112 thousand.

•Federal Home Loan Bank advances totaled $245.0 million at December 31, 2024 with a weighted average interest rate of 4.19%.

Asset Quality

•The ratio of criticized and classified loans to total loans decreased to 2.17% at December 31, 2024 from 2.59% at September 30, 2024 and from 2.32% at December 31, 2023, benefiting from the strategic sale of two nonperforming commercial real estate loans.

•Nonperforming loans were $92.4 million at December 31, 2024, compared to $80.9 million at September 30, 2024, and $65.1 million at December 31, 2023. New nonperforming loans in the fourth quarter of 2024 have collateral values well in excess of balances outstanding, and therefore, no loss is expected. Nonperforming loans to total loans outstanding were 0.90% at December 31, 2024, 0.79% at September 30, 2024, and 0.65% at December 31, 2023.

•Accruing past due loans were $15.6 million, or 0.15% of total loans, at December 31, 2024, compared to $50.7 million, or 0.50% of total loans, at September 30, 2024, and $30.5 million, or 0.30% of total loans, at December 31, 2023.

•Nonperforming assets to total assets were 0.65% at December 31, 2024, compared to 0.58% at September 30, 2024, and 0.50% at December 31, 2023.

•Theratio of allowance for credit losses to total loans was 1.34% at December 31, 2024, 1.38% at September 30, 2024, and 1.48% at December 31, 2023.

•Net charge-offs were $6.1 million in the fourth quarter of 2024, compared to $7.4 million in the third quarter of 2024 and $4.7 million in the fourth quarter of 2023. During the fourth quarter of 2024, the Company entered into arrangements to sell approximately $20.0 million in consumer fintech loans and, as a result, charged down these loans by $3.0 million.

•Portfolio diversification, in terms of asset mix, industry, and loan type, has been a critical element of the Company's lending strategy. Exposure across industries and collateral types is broadly distributed. Seacoast's average loan size is $383 thousand, and the average commercial loan size is $814 thousand, reflecting an ability to maintain granularity within the overall loan portfolio.

•Construction and land development and commercial real estate loans remain well below regulatory guidance as of December 31, 2024 at 38% and 237% of total bank-level risk-based capital2, respectively, compared to 36% and 241%, respectively, at September 30, 2024. On a consolidated basis and as of December 31, 2024, construction and land development and commercial real estate loans represent 36% and 224%, respectively, of total consolidated risk-based capital2.

Actual results may differ from those set forth in the forward-looking statements.

Forward-looking statements include statements with respect to the Company’s beliefs, plans, objectives, goals, expectations, anticipations, assumptions, estimates and intentions about future performance and involve known and unknown risks, uncertainties and other factors, which may be beyond the Company’s control, and which may cause the actual results, performance or achievements of Seacoast Banking Corporation of Florida (“Seacoast” or the “Company”) or its wholly-owned banking subsidiary, Seacoast National Bank (“Seacoast Bank”), to be materially different from results, performance or achievements expressed or implied by such forward-looking statements. You should not expect the Company to update any forward-looking statements.

All statements other than statements of historical fact could be forward-looking statements. You can identify these forward-looking statements through the use of words such as "may", "will", "anticipate", "assume", "should", "support", "indicate", "would", "believe", "contemplate", "expect", "estimate", "continue", "further", "plan", "point to", "project", "could", "intend", "target" or other similar words and expressions of the future. These forward-looking statements may not be realized due to a variety of factors, including, without limitation: the impact of current and future economic and market conditions generally (including seasonality) and in the financial services industry, nationally and within Seacoast’s primary market areas, including the effects of inflationary pressures, changes in interest rates, slowdowns in economic growth, and the potential for high unemployment rates, as well as the financial stress on borrowers and changes to customer and client behavior and credit risk as a result of the foregoing; potential impacts of adverse developments in the banking industry, including those highlighted by high-profile bank failures, and including impacts on customer confidence, deposit outflows, liquidity and the regulatory response thereto (including increases in the cost of our deposit insurance assessments), the Company's ability to effectively manage its liquidity risk and any growth plans, and the availability of capital and funding; governmental monetary and fiscal policies, including interest rate policies of the Board of Governors of the Federal Reserve, as

well as legislative, tax and regulatory changes including overdraft and late fee caps (if implemented), including those that impact the money supply and inflation; the risks of changes in interest rates on the level and composition of deposits (as well as the cost of, and competition for, deposits), loan demand, liquidity and the values of loan collateral, securities, and interest rate sensitive assets and liabilities; interest rate risks (including the impacts of interest rates on macroeconomic conditions, customer and client behavior, and on our net interest income), sensitivities and the shape of the yield curve; changes in accounting policies, rules and practices; changes in retail distribution strategies, customer preferences and behavior generally and as a result of economic factors, including heightened or persistent inflation; changes in the availability and cost of credit and capital in the financial markets; changes in the prices, values and sales volumes of residential and commercial real estate, especially as they relate to the value of collateral supporting the Company’s loans; the Company’s concentration in commercial real estate loans and in real estate collateral in Florida; Seacoast’s ability to comply with any regulatory requirements and the risk that the regulatory environment may not be conducive to or may prohibit or delay the consummation of future mergers and/or business combinations, may increase the length of time and amount of resources required to consummate such transactions, and may reduce the anticipated benefit; inaccuracies or other failures from the use of models, including the failure of assumptions and estimates, as well as differences in, and changes to, economic, market and credit conditions; the impact on the valuation of Seacoast’s investments due to market volatility or counterparty payment risk, as well as the effect of a decline in stock market prices on our fee income from our wealth management business; statutory and regulatory dividend restrictions; increases in regulatory capital requirements for banking organizations generally; the risks of mergers, acquisitions and divestitures, including Seacoast’s ability to continue to identify acquisition targets, successfully acquire and integrate desirable financial institutions and realize expected revenues and revenue synergies; changes in technology or products that may be more difficult, costly, or less effective than anticipated; the Company’s ability to identify and address increased cybersecurity risks, including those impacting vendors and other third parties which may be exacerbated by developments in generative artificial intelligence; fraud or misconduct by internal or external parties, which Seacoast may not be able to prevent, detect or mitigate; inability of Seacoast’s risk management framework to manage risks associated with the Company’s business; dependence on key suppliers or vendors to obtain equipment or services for the business on acceptable terms; reduction in or the termination of Seacoast’s ability to use the online- or mobile-based platform that is critical to the Company’s business growth strategy; the effects of war or other conflicts, acts of terrorism, natural disasters, including hurricanes in the Company’s footprint, health emergencies, epidemics or pandemics, or other catastrophic events that may affect general economic conditions and/or increase costs, including, but not limited to, property and casualty and other insurance costs; Seacoast’s ability to maintain adequate internal controls over financial reporting; potential claims, damages, penalties, fines, costs and reputational damage resulting from pending or future litigation, regulatory proceedings and enforcement actions; the risks that deferred tax assets could be reduced if estimates of future taxable income from the Company’s operations and tax planning strategies are less than currently estimated, the results of tax audit findings, challenges to our tax positions, or adverse changes or interpretations of tax laws; the effects of competition from other commercial banks, thrifts, mortgage banking firms, consumer finance companies, credit unions, non-bank financial technology providers, securities brokerage firms, insurance companies, money market and other mutual funds and other financial institutions; the failure of assumptions underlying the establishment of reserves for expected credit losses; risks related to, and the costs associated with, environmental, social and governance matters, including the scope and pace of related rulemaking activity and disclosure requirements; a deterioration of the credit rating for U.S. long-term sovereign debt, actions that the U.S. government may take to avoid exceeding the debt ceiling, and uncertainties surrounding the federal budget and economic policy, including the impact of tariffs and trade policies; the risk that balance sheet, revenue growth, and loan growth expectations may differ from actual results; and other factors and risks desc    ribed herein and under “Risk Factors” in any of the Company's subsequent reports filed with the SEC and available on its website at www.sec.gov.

All written or oral forward-looking statements attributable to us are expressly qualified in their entirety by this cautionary notice, including, without limitation, those risks and uncertainties described in the Company’s annual report on Form 10-K for the year ended December 31, 2023 and in other periodic reports that the Company files with the SEC.

Explanation of Certain Unaudited Non-GAAP Financial Measures

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

EARNINGS PRESENTATION FOURTH QUARTER 2024 2024

2FOURTH QUARTER 2024 EARNINGS PRESENTATION Cautionary Notice Regarding Forward-Looking Statements This presentation contains “forward-looking statements” within the meaning, and protections, of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended, including, without limitation, statements about future financial and operating results, cost savings, enhanced revenues, economic and seasonal conditions in the Company’s markets, and improvements to reported earnings that may be realized from cost controls, tax law changes, new initiatives and for integration of banks that the Company has acquired, or expects to acquire, as well as statements with respect to Seacoast's objectives, strategic plans, expectations and intentions and other statements that are not historical facts. Actual results may differ from those set forth in the forward-looking statements. Forward-looking statements include statements with respect to the Company’s beliefs, plans, objectives, goals, expectations, anticipations, assumptions, estimates and intentions about future performance, and involve known and unknown risks, uncertainties and other factors, which may be beyond the Company’s control, and which may cause the actual results, performance or achievements of Seacoast Banking Corporation of Florida (“Seacoast” or the “Company”) or its wholly-owned banking subsidiary, Seacoast National Bank (“Seacoast Bank”), to be materially different from results, performance or achievements expressed or implied by such forward-looking statements. You should not expect the Company to update any forward-looking statements. All statements other than statements of historical fact could be forward-looking statements. You can identify these forward- looking statements through the use of words such as "may", "will", "anticipate", "assume", "should", "support", "indicate", "would", "believe", "contemplate", "expect", "estimate", "continue", "further", "plan", "point to", "project", "could", "intend", "target" or other similar words and expressions of the future. These forward-looking statements may not be realized due to a variety of factors, including, without limitation: the impact of current and future economic and market conditions generally (including seasonality) and in the financial services industry, nationally and within Seacoast’s primary market areas, including the effects of inflationary pressures, changes in interest rates, slowdowns in economic growth, and the potential for high unemployment rates, as well as the financial stress on borrowers and changes to customer and client behavior and credit risk as a result of the foregoing; potential impacts of adverse developments in the banking industry including those highlighted by high- profile bank failures, and including impacts on customer confidence, deposit outflows, liquidity and the regulatory response thereto (including increases in the cost of our deposit insurance assessments), the Company's ability to effectively manage its liquidity risk and any growth plans, and the availability of capital and funding; governmental monetary and fiscal policies, including interest rate policies of the Board of Governors of the Federal Reserve, as well as legislative, tax and regulatory changes including overdraft and late fee caps (if implemented), including those that impact the money supply and inflation; the risks of changes in interest rates on the level and composition of deposits (as well as the cost of, and competition for, deposits), loan demand, liquidity and the values of loan collateral, securities, and interest rate sensitive assets and liabilities; interest rate risks (including the impacts of interest rates on macroeconomic conditions, customer and client behavior, and on our net interest income), as well as the impact of prolonged elevated interest rates on our financial projections and models, sensitivities and the shape of the yield curve; changes in accounting policies, rules and practices; changes in retail distribution strategies, customer preferences and behavior generally and as a result of economic factors, including heightened or persistent inflation; changes in the availability and cost of credit and capital in the financial markets; changes in the prices, values and sales volumes of residential and commercial real estate, especially as they relate to the value of collateral supporting the Company’s loans; the Company’s concentration in commercial real estate loans and in real estate collateral in Florida; Seacoast’s ability to comply with any regulatory requirements; the risk that the regulatory environment may not be conducive to or may prohibit or delay the consummation of future mergers and/or business combinations, may increase the length of time and amount of resources required to consummate such transactions, and may reduce the anticipated benefit; inaccuracies or other failures from the use of models, including the failure of assumptions and estimates, as well as differences in, and changes to, economic, market and credit conditions; the impact on the valuation of Seacoast’s investments due to market volatility or counterparty payment risk, as well as the effect of a decline in stock market prices on our fee income from our wealth management business; statutory and regulatory dividend restrictions; increases in regulatory capital requirements for banking organizations generally; the risks of mergers, acquisitions and divestitures, including Seacoast’s ability to continue to identify acquisition targets, successfully acquire and integrate desirable financial institutions and realize expected revenues and revenue synergies; changes in technology or products that may be more difficult, costly, or less effective than anticipated; the Company’s ability to identify and address increased cybersecurity risks, including those impacting vendors and other third parties which may be exacerbated by developments in generative artificial intelligence; fraud or misconduct by internal or external parties, which Seacoast may not be able to prevent, detect or mitigate; inability of Seacoast’s risk management framework to manage risks associated with the Company’s business; dependence on key suppliers or vendors to obtain equipment or services for the business on acceptable terms; reduction in or the termination of Seacoast’s ability to use the online- or mobile-based platform that is critical to the Company’s business growth strategy; the effects of war or other conflicts, acts of terrorism, natural disasters, including hurricanes in the Company’s footprint, health emergencies, epidemics or pandemics, or other catastrophic events that may affect general economic conditions and/or increase costs, including, but not limited to, property and casualty and other insurance costs; Seacoast’s ability to maintain adequate internal controls over financial reporting; potential claims, damages, penalties, fines, costs and reputational damage resulting from pending or future litigation, regulatory proceedings and enforcement actions; the risks that deferred tax assets could be reduced if estimates of future taxable income from the Company’s operations and tax planning strategies are less than currently estimated, the results of tax audit findings, challenges to our tax positions, or adverse changes or interpretations of tax laws; the effects of competition from other commercial banks, thrifts, mortgage banking firms, consumer finance companies, credit unions, non-bank financial technology providers, securities brokerage firms, insurance companies, money market and other mutual funds and other financial institutions; the failure of assumptions underlying the establishment of reserves for expected credit losses; risks related to, and the costs associated with, environmental, social and governance matters, including the scope and pace of related rulemaking activity and disclosure requirements; a deterioration of the credit rating for U.S. long-term sovereign debt, actions that the U.S. government may take to avoid exceeding the debt ceiling, and uncertainties surrounding the federal budget and economic policy, including the impact of tariffs and trade policies; the risk that balance sheet, revenue growth, and loan growth expectations may differ from actual results; and other factors and risks described herein and under “Risk Factors” and in any of the Company's subsequent reports filed with the SEC and available on its website at www.sec.gov. All written or oral forward-looking statements attributable to us are expressly qualified in their entirety by this cautionary notice, including, without limitation, those risks and uncertainties described in the Company’s annual report on Form 10-K for the year ended December 31, 2023 and in other periodic reports that the Company files with the SEC. Such reports are available upon request from the Company, or from the Securities and Exchange Commission, including through the SEC's Internet website at www.sec.gov.

22FOURTH QUARTER 2024 EARNINGS PRESENTATION This presentation contains financial information determined by methods other than Generally Accepted Accounting Principles (“GAAP”). The financial highlights provide reconciliations between GAAP and adjusted financial measures including net income, noninterest income, noninterest expense, tax adjustments and other financial ratios. Management uses these non-GAAP financial measures in its analysis of the Company’s performance and believes these presentations provide useful supplemental information, and a clearer understanding of the Company’s performance. The Company believes the non-GAAP measures enhance investors’ understanding of the Company’s business and performance and if not provided would be requested by the investor community. These measures are also useful in understanding performance trends and facilitate comparisons with the performance of other financial institutions. The limitations associated with operating measures are the risk that persons might disagree as to the appropriateness of items comprising these measures and that different companies might define or calculate these measures differently. The Company provides reconciliations between GAAP and these non-GAAP measures. These disclosures should not be considered an alternative to GAAP.
