Third Quarter 2026 Highlights

Charles M.

This press release 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 or impacts to reported earnings that may be realized from cost controls, tax law changes, conversion of preferred shares into common shares, 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. The Company undertakes no obligation to update any forward-looking statements, whether as a result of new information, future events or otherwise, except as required by law.

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. Forward-looking statements also include statements relating to expectations regarding net interest income, net interest margin, loan growth, deposit growth and mix, credit quality, noninterest income and expense, capital levels and liquidity. 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 continued inflationary pressures, changes in interest rates, tariffs or trade wars (including reduced consumer spending), 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, or as encountered by other financial institutions that adversely affect Seacoast, 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 risks related to legislative, tax and regulatory changes, including those that impact the money supply and inflation; the risks of continued 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, 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 borrower credit risks and payment behaviors, and 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 (including with respect to our financial statements), 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, and limit deposit, customer and employee attrition; changes in technology or products that may be more difficult, costly, or less effective than anticipated; the timely development and acceptance of new products and services as well as risks (including reputational and litigation) attendant thereto, and perceived overall value of these products and services by users; risks associated with the development and use of artificial intelligence; 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, regime change, civil unrest, 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 or actual claims, damages, penalties, fines, costs, unexpected outcomes and reputational damage resulting from new, existing, 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 (including the inability to grow, or attrition of deposits, customers, and employees) from other commercial banks, thrifts, mortgage banking firms, consumer finance companies, credit unions, non-bank financial technology providers, securities brokerage firms, insurance companies, private credit funds, money market and other mutual funds and other financial institutions; the failure of assumptions underlying the establishment of reserves for expected credit losses; impairment of our goodwill or other intangible assets, risks related to, and the costs associated with, environmental, social and governance matters (“ESG”) and anti-ESG matters, including the scope and pace of related rulemaking activity and disclosure requirements and potential litigation and enforcement; legislative, regulatory or supervisory actions related to so-called “de-banking,” including any new prohibitions, requirements or enforcement priorities that could affect customer relationships, compliance obligations, or operational practices; government actions or inactions, including 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” 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, 2025 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.

2Calculated on a fully taxable equivalent basis using amortized cost.

3These ratios are stated on an annualized basis and are not necessarily indicative of future periods.

4The Company defines tangible assets as total assets less intangible assets, tangible equity as total shareholders' equity plus convertible preferred stock less intangible assets, and tangible common equity as total shareholders' equity less intangible assets.

5Defined as noninterest expense less provision for credit losses on unfunded commitments and gains, losses, and expenses on foreclosed properties divided by net operating revenue (net interest income on a fully taxable equivalent basis plus noninterest income excluding securities gains and losses). Prior to the fourth quarter of 2025, the Company's presentation of the efficiency ratio excluded amortization expense on intangible assets. Prior periods have been updated to align with the current presentation.

6Calculated treating all convertible preferred shares as common. Each 1/1000 th preferred share is convertible to one common share on the date a holder of preferred stock transfers such share of preferred stock to a non-affiliate of the holder. The Company believes a calculation presenting all convertible preferred shares as common provides useful supplemental information to the presentation of common share measures, as we anticipate they will be converted to common shares in the future.

7In the fourth quarter of 2025, non-voting convertible preferred shares were issued in connection with the VBI acquisition. Those shares earn dividends pro-rata with common shares.

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.
