I could not be more proud of our team for delivering an exceptionally smooth client experience while executing a highly complex technical conversion. Their preparation, commitment, and relentless focus on excellence ensured a seamless transition for customers and demonstrated the extraordinary talent and capabilities that exist throughout Seacoast. Shaffer continued, “The Villages® remains one of the most attractive growth markets in Florida, supported by exceptional demographics, continued economic expansion, and significant opportunities to deepen customer relationships. This acquisition has strengthened our position in this premier market, expanded our franchise, enhanced our earnings profile, and improved our ability to generate sustainable long-term growth. Just as importantly, we have welcomed team members and customers that share our commitment to community banking, exceptional service, and local decision-making. “Beyond the successful completion of the conversion, we delivered another strong quarter, supported by healthy loan and demand deposit growth, diversified revenue streams, and disciplined execution across the organization. Our balance sheet remains exceptionally strong, underpinned by industry-leading capital levels, substantial liquidity, and excellent asset quality. These strengths provide the flexibility to continue to invest in our franchise, support our clients, and capitalize on opportunities across our footprint while maintaining a prudent risk posture. Shaffer concluded, “As Seacoast celebrates its 100 year, we remain optimistic about the future. The markets we serve continue to benefit from favorable population growth, strong economic fundamentals, and attractive long-term growth trends. With the successful integration of our recent acquisitions now complete, an outstanding team in place, and a strong balance sheet supporting future growth, we enter the second half of 2026 with considerable momentum and confidence in our ability to create sustained value for our shareholders, customers, associates, and communities.” 1 1 th Non-GAAP measure, see “Explanation of Certain Unaudited Non-GAAP Financial Measures" for more information and for a reconciliation to GAAP.1

Calculated on a fully taxable equivalent basis using amortized cost. These ratios are stated on an annualized basis and are not necessarily indicative of future periods. The Company defines tangible assets as total assets less intangible assets, tangible equity as total shareholders' equity plus convertible preferred stock less intangibleassets, and tangible equity as total shareholders' equity less intangible assets. Defined as noninterest expense less provision for credit losses on unfunded commitments and gains, losses, and expenses on foreclosed properties divided by net operatingrevenue (net interest income on a fully taxable equivalent basis plus noninterest income excluding securities gains and losses). Prior to the fourth quarter of 2025, theCompany's presentation of the efficiency ratio excluded amortization expense on intangible assets. Prior periods have been updated to align with the current presentation. Calculated treating all convertible preferred shares as common. Each 1/1000 preferred share is convertible to one common share on the date a holder of preferred stocktransfers such share of preferred stock to a non-affiliate of the holder. The Company believes a calculation presenting all convertible preferred shares as common providesuseful supplemental information to the presentation of common share measures, as we anticipate they will be converted to common shares in the future. In the fourth quarter of 2025, non-voting convertible preferred shares were issued in connection with the VBI acquisition. Those shares earn dividends pro-rata withcommon shares, or $0.19 per 1/1000 preferred share. 1 2 2,3 1 1 3 1,3 3,4 1,3,4 1,3,4 3 1,3 3,4 1,3,4 5 1 4 4 1 6 4,6 7 1 2 3 4 5 6 th 7 th

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.
