Accounting Policies [Abstract]

Basis of Presentation

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 months ended March 31, 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 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.
