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;

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 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;

25FEBRUARY 2026 INVESTOR PRESENTATION Securities Repositioning Leverages Strong Capital Position Strong capital levels with lower than projected dilution from the VBI acquisition provided the opportunity to further optimize the securities portfolio and accelerate our path to stronger earnings. In January 2026, the Company repositioned a portion of its available for sale portfolio. Securities with an average book yield of 1.9% were sold, resulting in a pre-tax loss of approximately $39.5 million impacting first quarter 2026 results. The proceeds of approximately $277 million were reinvested in primarily agency mortgage-backed securities with an average taxable equivalent book yield of 4.8%. The transaction is expected to be immediately accretive to earnings, net interest margin and return on assets, while having a neutral effect on total equity and tangible book value.

Accretion on acquired loans of $10.6 million, net of amortization of intangibles of $10.4 million in Q4 2025 had no impact to the diluted earnings per share. The $4.4 million increase in amortization expense is a result of the additional intangible assets from the VBI acquisition. For the full year 2025, accretion on acquired loans of $39.0 million, net of amortization of intangibles of $26.8 million contributed only ten cents to diluted earnings per share.

31FEBRUARY 2026 INVESTOR PRESENTATION About Non-GAAP Financial Measures: 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. Presentation of Non-GAAP Financial Measures: Certain monetary amounts, percentages and other figures included in this report have been subject to rounding adjustments. Accordingly, figures shown as totals in certain tables may not be the arithmetic aggregation of the figures that precede them and the total of the four quarters may not be the arithmetic aggregation of the year-to-date value.
