Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation Basis of Presentation: The accompanying unaudited condensed consolidated financial statements of Seacoast Banking Corporation of Florida and its subsidiaries (the “Company”) have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, they 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 and nine months ended September 30, 2022, are not necessarily indicative of the results that may be expected for the year ending December 31, 2022, 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, 2021. Use of Estimates: The preparation of these condensed 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 determination of the allowance for credit losses, acquisition accounting and purchased loans, intangible assets and impairment testing, other fair value measurements and contingent liabilities. Recently Issued Accounting Standards, Not Yet Adopted In March 2022, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2022-02, Financial Instruments Credit Losses (Topic 326), Troubled Debt Restructurings and Vintage Disclosures . ASU 2022-02 eliminates the accounting guidance for troubled debt restructurings (“TDRs”) in ASC 310-40, Receivables - Troubled Debt Restructurings by Creditors , and introduces new disclosures related to modifications with borrowers that are experiencing financial difficulties. ASU 2022-02 also requires the disclosure of current-period gross write-offs by year of origination for financing receivables held at amortized cost. The amendments in ASU 2022-02 are effective for fiscal years beginning after December 15, 2022, and early adoption is permitted. The impact to the Company’s consolidated financial statements of the adoption of ASU 2022-02 is not expected to be material.

No gain or loss was recognized on the sale. There were no other sales of securities during the three and nine months ended September 30, 2022. Proceeds from the sales of securities for the three and nine months ended September 30, 2021 were $1.0 million, and $57.2 million, respectively, resulting in gross gains of $0.2 million and gross losses of $0.3 million. Also included in “Securities losses, net” are decreases of $0.4 million and $1.1 million for the three and nine months ended September 30, 2022, respectively, and decreases of $30 thousand and $0.1 million for the three and nine months ended September 30, 2021, respectively, in the value of an investment in shares of a mutual fund that invests in CRA-qualified debt securities. During the first quarter of 2021, the Company reclassified debt securities with an amortized cost of $210.8 million from available-for-sale to held-to-maturity, as it has the ability and intent to hold these securities to maturity. These securities had net unrealized gains of $0.8 million at the date of transfer, which will continue to be reported in accumulated other comprehensive income, and will be amortized over the remaining life of the securities as an adjustment of yield. The effect on interest income of the amortization of net unrealized gains is offset by the amortization of the premium on the securities transferred. At September 30, 2022, debt securities with a fair value of $387.8 million were pledged primarily as collateral for public deposits and secured borrowings. The amortized cost and fair value of securities at September 30, 2022, by contractual maturity, are shown below. Expected maturities will differ from contractual maturities because prepayments of the underlying collateral for these securities may occur, due to the right to call or repay obligations with or without call or prepayment penalties. Securities not due at a single maturity date are shown separately.

These securities are either explicitly or implicitly guaranteed by the U.S. government and have a long history of no credit losses. The implied government guarantee of principal and interest payments and the high credit rating of the portfolio provide a sufficient basis for the current expectation that there is no risk of loss if default were to occur. Based on the assessment of all relevant factors, the Company believes that the unrealized loss positions on these debt securities are a function of changes in investment spreads and interest rate movements and not changes in credit quality, and expects to recover the entire amortized cost basis of these securities. Therefore, at September 30, 2022, no allowance for credit losses has been recorded. At September 30, 2022, the Company had $12.1 million of unrealized losses in floating rate collateralized loan obligations (“CLOs”) having a fair value of $302.1 million. CLOs are special purpose vehicles and those in which the Company has invested acquire nearly all first-lien, broadly syndicated corporate loans across a diversified band of industries while providing support to senior tranche investors. As of September 30, 2022, all positions held by the Company are in AAA and AA tranches, with average credit support of 37% and 36%, respectively. The Company evaluates the securities for potential credit losses by modeling expected loan-level defaults, recoveries, and prepayments for each CLO security. Based on the assessment of all relevant factors, the Company believes that the unrealized loss positions on these debt securities are a function of changes in investment spreads and interest rate movements and not changes in credit quality, and expects to recover the entire amortized cost basis of these securities. Therefore, at September 30, 2022, no allowance for credit losses has been recorded. At September 30, 2022, the Company had $11.8 million of unrealized losses on private label residential and commercial mortgage-backed securities and collateralized mortgage obligations having a fair value of $170.7 million. The collateral underlying these mortgage investments is primarily residential real estate. The securities have average credit support of 20%. Based on the assessment of all relevant factors, the Company believes that the unrealized loss positions on these debt securities are a function of changes in investment spreads and interest rate movements and not changes in credit quality, and expects to recover the entire amortized cost basis of these securities. Therefore, at September 30, 2022, no allowance for credit losses has been recorded. At September 30, 2022, the Company had $2.3 million of unrealized losses on municipal securities having a fair value of $23.5 million. These securities are highly rated issuances of state or local municipalities, all of which are continuing to make timely contractual payments. Based on the assessment of all relevant factors, the Company believes that the unrealized loss positions on these debt securities are a function of changes in investment spreads and interest rate movements and not changes in credit quality, and expects to recover the entire amortized cost basis of these securities. As a result, as of September 30, 2022, no allowance for credit losses has been recorded. All held-to-maturity (“HTM”) debt securities are issued by government-sponsored entities, which are either explicitly or implicitly guaranteed by the U.S. government and have a long history of no credit losses. While the potential for default on these securities may be something greater than zero, the long history with no credit losses, the implied government guarantee of principal and interest payments and the high credit rating of the HTM portfolio provide sufficient basis for the current expectation that there is no risk of loss if default were to occur. As a result, as of September 30, 2022, no allowance for credit losses has been recorded. Included in Other Assets at September 30, 2022 is $38.2 million of Federal Home Loan Bank and Federal Reserve Bank stock stated at par value. The Company has not identified events or changes in circumstances, which may have a significant adverse effect on the fair value of these cost method investment securities. Accrued interest receivable on available-for-sale (“AFS”) securities and HTM debt securities of $5.8 million and $1.3 million, respectively, at September 30, 2022, and $3.4 million and $1.0 million, respectively, at December 31, 2021, is included in Other Assets. Also included in Other Assets is an $8.2 million investment in a CRA-qualified mutual fund carried at fair value.

Receivables [Abstract]
Loans	LoansLoans held for investment are categorized into the following segments: • Construction and land development: Loans are extended to both commercial and consumer customers which are collateralized by and for the purpose of funding land development and construction projects, including 1-4 family residential construction, multi-family property and non-farm residential property where the primary source of repayment is from proceeds of the sale, refinancing or permanent financing of the property. • Commercial real estate - owner-occupied: Loans are extended to commercial customers for the purpose of acquiring real estate to be occupied by the borrower's business. These loans are collateralized by the subject property and the repayment of these loans is largely dependent on the performance of the company occupying the property. • Commercial real estate - non owner-occupied: Loans are extended to commercial customers for the purpose of acquiring commercial property where occupancy by the borrower is not their primary intent. These loans are viewed primarily as cash flow loans, collateralized by the subject property, and the repayment of these loans is largely dependent on rental income from the successful operation of the property. • Residential real estate: Loans are extended to consumer customers and collateralized primarily by 1-4 family residential properties and include fixed and variable rate mortgages, home equity mortgages, and home equity lines of credit. Loans are primarily written based on conventional loan agency guidelines, including loans that exceed agency value limitations. Sources of repayment are largely dependent on the occupant of the residential property. • Commercial and financial: Loans are extended to commercial customers. The purpose of the loans can be working capital, physical asset expansion, asset acquisition or other business purposes. Loans may be collateralized by assets owned by the borrower or the borrower's business. Commercial loans are based primarily on the historical and projected cash flow of the borrower's business and secondarily on the capacity of credit enhancements, guarantees and underlying collateral provided by the borrower. • Consumer: Loans are extended to consumer customers. The segment includes both installment loans and lines of credit which may be collateralized or non-collateralized. • Paycheck Protection Program (“PPP”): Loans originated under a temporary program established by the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”), and extended by the Economic Aid Act. Under the terms of the program, balances may be forgiven if the borrower uses the funds in a manner consistent with the program guidelines, and repayment is guaranteed by the U.S. government. In the third quarter of 2022, to align with the Company’s transition of the calculation of expected credit losses to a new modeling tool, $100 million in loans to commercial borrowers collateralized by residential properties were reclassified from “Residential real estate” to “Commercial real estate - non owner-occupied.” The following tables present net loan balances by segment as of: September 30, 2022 (In thousands) Portfolio Loans Acquired Non-PCD Loans PCD Loans Total Construction and land development $ 338,070 $ 23,808 $ 35 $ 361,913 Commercial real estate - owner-occupied 988,614 245,943 18,902 1,253,459 Commercial real estate - non owner-occupied 1,568,138 469,363 70,113 2,107,614 Residential real estate 1,488,359 106,597 4,809 1,599,765 Commercial and financial 1,091,665 78,406 12,313 1,182,384 Consumer 176,895 3,521 — 180,416 Paycheck Protection Program 1,616 3,678 — 5,294 Totals $ 5,653,357 $ 931,316 $ 106,172 $ 6,690,845 December 31, 2021 (In thousands) Portfolio Loans Acquired Non-PCD Loans PCD Loans Total Construction and land development $ 199,341 $ 31,438 $ 45 $ 230,824 Commercial real estate - owner occupied 983,517 186,812 27,445 1,197,774 Commercial real estate - non-owner occupied 1,278,180 382,554 75,705 1,736,439 Residential real estate 1,261,306 156,957 7,091 1,425,354 Commercial and financial 968,318 84,395 16,643 1,069,356 Consumer 169,507 4,658 10 174,175 Paycheck Protection Program 69,503 21,604 — 91,107 Totals $ 4,929,672 $ 868,418 $ 126,939 $ 5,925,029 The amortized cost basis of loans at September 30, 2022 included net deferred costs of $30.1 million. At December 31, 2021, the amortized cost basis included net deferred costs of $31.0 million on non-PPP portfolio loans and net deferred fees of $2.4 million on PPP loans. At September 30, 2022, the remaining fair value adjustments on acquired loans were $19.1 million, or 1.8% of the outstanding acquired loan balances, compared to $23.1 million, or 2.3% of the acquired loan balances at December 31, 2021. The discount is accreted into interest income over the remaining lives of the related loans on a level yield basis. Accrued interest receivable is included within Other Assets and was $17.6 million and $14.7 million at September 30, 2022 and December 31, 2021, respectively.

Repayment of principal and interest is fully guaranteed by the U.S. government. All interest accrued but not received for loans placed on nonaccrual is reversed against interest income. Interest subsequently received on such loans is accounted for under the cost-recovery method, whereby interest income is not recognized until the loan balance is reduced to zero. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current, and future payments are reasonably assured. The Company recognized $0.2 million and $0.3 million in interest income on nonaccrual loans during each of the three months ended September 30, 2022 and 2021, respectively.

The following classifications are used to categorize loans under the internal classification system: • Pass: Loans that are not problem loans or potential problem loans are considered to be pass-rated. • Special Mention: Loans that do not currently expose the Company to sufficient risk to warrant classification in the Substandard or Doubtful categories, but possess weaknesses that deserve management's close attention are deemed to be Special Mention. • Substandard: Loans with the distinct possibility that the Company will sustain some loss if the deficiencies are not corrected. • Substandard Impaired: Loans typically placed on nonaccrual and considered to be collateral-dependent or accruing TDRs. • Doubtful: Loans that have all the weaknesses inherent in those classified Substandard with the added characteristic that the weakness present makes collection or liquidation in full, on the basis of currently existing facts, conditions and values, highly questionable and improbable. The principal balance of loans classified as doubtful are likely to be charged off.

During the nine months ended September 30, 2021, there were two defaults on loans totaling $0.1 million that had been modified to a TDR within the preceding twelve months. The Company considers a loan to have defaulted when it becomes 90 days or more delinquent under the modified terms, has been transferred to nonaccrual status, is charged off or has been transferred to other real estate owned. For loans measured based on the present value of expected future cash flows, $13 thousand and $9 thousand for the three months ended September 30, 2022, and 2021, respectively, and $33 thousand and $20 thousand for the nine months ended September 30, 2022, and 2021, respectively, was included in interest income and represents the change in present value attributable to the passage of time.

Forecast data is sourced from Moody’s Analytics (“Moody’s”), a firm widely recognized for its research, analysis, and economic forecasts. The forecasts of future economic conditions are over a period that has been deemed reasonable and supportable, and in segments where it can no longer develop reasonable and supportable forecasts, the Company reverts to longer-term historical loss experience to estimate losses over the remaining life of the loans. During the third quarter of 2022, the Company transitioned to a tool that calculates the quantitative portion of expected credit losses using a discounted cash flow methodology for its commercial loans and using a loss rate methodology for its consumer loans. As of September 30, 2022, the Company utilized a blend of Moody’s most recent “U.S. Macroeconomic Outlook Baseline” and “Alternative Scenario 3 - Downside - 90th Percentile” scenarios and considered the uncertainty associated with the assumptions in both scenarios, including continued actions taken by the Federal Reserve with regard to monetary policy and interest rates and the potential impact of those actions, the ongoing Russia-Ukraine conflict and the magnitude of the resulting market disruption, the potential impact of persistent high inflation on economic growth and expectations around a recession occurring over the next 12 to 24 months. Furthermore, the Company considered the impact that Hurricane Ian may have on future losses, and as a result increased the allowance by $2.1 million. Outcomes in any or all of these factors could differ from the scenarios identified above, and the Company incorporated qualitative considerations reflecting the risk of uncertain economic conditions, and for additional dimensions of risk not captured in the quantitative model. The following section discusses changes in the level of the allowance for credit losses for the three months ended September 30, 2022. In the Construction and Land Development segment, the increase in reserves reflects higher loan balances as well as a more negative economic outlook. In this segment, the primary source of repayment is typically from proceeds of the sale, refinancing, or permanent financing of the underlying property; therefore, collateral type and estimated collateral values are among the relevant factors in assessing expected losses. In the Commercial Real Estate - Owner-Occupied segment, the decrease in the allowance is primarily attributed to the transition to a discounted cash flow approach which, while continuing to consider relevant macroeconomic forecast variables, also considers loan-specific available collateral. In the Commercial Real Estate - Non Owner-Occupied segment, the decrease in reserves reflects the impact of transitioning from a portfolio level estimate to a discounted cash flow approach, utilizing macroeconomic variables specific to the loan segment. Repayment is often dependent upon rental income from the successful operation of the underlying property. Collateral type, estimated collateral values, loan seasoning, and note structure are among the risk characteristics analyzed for this segment. The Residential Real Estate segment includes first mortgages secured by residential property, and home equity lines of credit. The increase in reserves is due to a deterioration in the economic forecast, including the transition to a loss rate tool for estimating credit losses, utilizing macroeconomic variables specific to the loan segment. Risk characteristics considered for this segment include, but are not limited to, collateral type, note structure, FICO score, location, and loan seasoning. In the Commercial and Financial segment, borrowers are primarily small to medium sized professional firms and other businesses, and loans are generally supported by projected cash flows of the business, collateralized by business assets, and/or guaranteed by the business owners. The decrease in reserves is attributed to the transition from a portfolio level estimate to a discounted cash flow tool, utilizing macroeconomic variables specific to the loan segment. Industry, collateral type, estimated collateral values, and loan seasoning are among the relevant factors in assessing expected losses. Consumer loans include installment and revolving lines, loans for automobiles, boats, and other personal or family purposes. Risk characteristics considered for this segment include, but are not limited to, collateral type, loan seasoning and FICO score. The increase in reserves reflects the increasing likelihood of economic recession reflected within the forecast.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives	Derivatives Back-to-Back Swaps The Company offers interest rate swaps when requested by customers to allow them to hedge the risk of rising interest rates on their variable rate loans. Upon entering into these swaps, the Company enters into offsetting positions with counterparties in order to minimize the interest rate risk. These back-to-back swaps qualify as freestanding financial derivatives with the fair values reported in other assets and other liabilities. The Company is party to master netting arrangements with its financial institution counterparties; however, the Company does not offset assets and liabilities under the arrangements for financial statement presentation purposes. Gains and losses on these back-to-back swaps, which offset, are recorded through noninterest income. No net gains or losses have been recognized to date on these instruments. As of September 30, 2022, the interest rate swaps had an aggregate notional value of $302.8 million, with a fair value of $24.1 million recorded in other assets and other liabilities. As of December 31, 2021, the interest rate swaps had an aggregate notional value of $175.4 million, with a fair value of $8.0 million recorded in other assets and other liabilities. The weighted average maturity was 6.8 years at September 30, 2022 and 6.7 years at December 31, 2021. Interest Rate Floors Designated as Cash Flow Hedges The Company has entered into interest rate floor contracts to mitigate exposure to the variability of future cash flows due to changes in interest rates on certain segments of its variable-rate loans. During 2020, the Company entered into two interest rate floor contracts, each with a notional amount of $150.0 million, maturing in October 2023 and November 2023. The Company considers these derivatives to be highly effective at achieving offsetting changes in cash flows attributable to changes in interest rates and has designated them as cash flow hedges. Therefore, changes in the fair value of these derivative instruments are recognized in other comprehensive income. Amortization of the premium paid on cash flow hedges is recognized in earnings over the term of the hedge in the same caption as the hedged item. For the three and nine months ended September 30, 2022, the Company recognized a loss through other comprehensive income of $0.1 million and $0.3 million, respectively, and reclassified $0.1 million and $0.3 million, respectively, out of accumulated other comprehensive income and into interest income. As of September 30, 2022 and December 31, 2021, the interest rate floors had a fair value of $20 thousand and $290 thousand, respectively, recorded in other assets in the consolidated balance sheet. Over the next twelve months, the Company expects to reclassify $0.6 million from accumulated other comprehensive income into interest income related to these agreements.

Recurring fair value basis is determined using market quotations. Available-for-sale debt securities : Level 1 securities consist of U.S. Treasury securities. Other securities are reported at fair value utilizing Level 2 inputs. The estimated fair value of a security is determined based on market quotations when available or, if not available, by using quoted market prices for similar securities, pricing models or discounted cash flow analyses, using observable market data where available. The Company reviews the prices supplied by independent pricing services, as well as their underlying pricing methodologies, for reasonableness and to ensure such prices are aligned with traditional pricing matrices. The fair value of collateralized loan obligations is determined from broker quotes. From time to time, the Company will validate, on a sample basis, prices supplied by the independent pricing service by comparison to prices obtained from other brokers and third-party sources or derived using internal models. Derivative financial instruments : The Company offers interest rate swaps to certain loan customers to allow them to hedge the risk of rising interest rates on their variable rate loans. The Company originates a variable rate loan and enters into a variable-to-fixed interest rate swap with the customer. The Company also enters into an offsetting swap with a correspondent bank. These back-to-back agreements are intended to offset each other and allow the Company to originate a variable rate loan, while providing a contract for fixed interest payments for the customer. The fair value of these derivatives is based on a discounted cash flow approach. Due to the observable nature of the inputs used in deriving the fair value of these derivative contracts, the valuation of interest rate swaps is classified as Level 2. Other derivatives consist of interest rate floors designated as cash flow hedges. The fair values of these instruments are based upon the estimated amount the Company would receive or pay to terminate the instruments, taking into account current interest rates and, when appropriate, the current creditworthiness of the counterparties. Interest rate floors designated as cash flow hedges are classified within Level 2. Loans held for sale : Fair values are based upon estimated values to be received from independent third party purchasers. These loans are intended for sale and the Company believes that the fair value is the best indicator of the resolution of these loans. Fair market value changes occur due to changes in interest rates, the borrower’s credit, the secondary loan market and the market for a borrower’s debt. Interest income is recorded based on the contractual terms of the loan and in accordance with the Company’s policy on loans held for investment. None of the loans were 90 days or more past due or on nonaccrual as of September 30, 2022 and December 31, 2021. The aggregate fair value and contractual balance of loans held for sale as of September 30, 2022 and December 31, 2021 is as follows: (In thousands) September 30, 2022 December 31, 2021 Aggregate fair value $ 1,620 $ 31,791 Contractual balance 1,565 30,963 Excess 55 828 Loans : Loans measured at fair value consist of collateral-dependent real estate loans. Fair value is based on recent real estate appraisals less estimated costs of sale. These evaluations may use either a single valuation approach or a combination of approaches, such as comparative sales, cost and/or income approach. A significant unobservable input in the income approach is the estimated capitalization rate for a given piece of collateral. At September 30, 2022 capitalization rates utilized to determine fair value of the underlying collateral averaged approximately 6.8%. Adjustments to comparable sales may be made by an appraiser to reflect local market conditions or other economic factors and may result in changes in the fair value of an asset over time. As such, the fair value of these loans is considered level 3 in the fair value hierarchy. Collateral-dependent loans measured at fair value totaled $9.9 million with a specific reserve of $3.9 million at September 30, 2022, compared to $13.1 million with a specific reserve of $4.7 million at December 31, 2021. Other real estate owned : When appraisals are used to determine fair value and the appraisals are based on a market approach, the fair value of other real estate owned (“OREO”) is classified as a Level 2 input. When the fair value of OREO is based on appraisals which require significant adjustments to market-based valuation inputs or apply an income approach based on unobservable cash flows, the fair value of OREO is classified as Level 3. Transfers between levels of the fair value hierarchy are recognized on the actual date of the event or circumstances that caused the transfer, which generally coincides with the Company’s monthly and/or quarterly valuation process. During the nine months ended September 30, 2022, an updated appraisal was obtained on a former branch property, and the value was transferred from Level 3 to Level 2. There were no transfers during the nine months ended September 30, 2021. The carrying amount and fair value of the Company’s other financial instruments that were not disclosed previously in the balance sheet and for which carrying amount is not fair value as of September 30, 2022 and December 31, 2021 is as follows: (In thousands) Carrying Amount Quoted Prices in Active Markets for Identical Assets Significant Other Observable Inputs Significant Unobservable Inputs September 30, 2022 Financial Assets Debt securities held-to-maturity 1 $ 774,706 $ — $ 645,439 $ — Time deposits with other banks 4,481 — 4,266 — Loans, net 6,589,526 — — 6,525,588 Financial Liabilities Deposit liabilities 8,765,414 — — 8,753,505 Subordinated debt 71,857 — 69,552 — December 31, 2021 Financial Assets Debt securities held-to-maturity 1 $ 638,640 $ — $ 627,398 $ — Loans, net 5,833,271 — — 5,907,447 Financial Liabilities Deposit liabilities 8,067,589 — — 8,067,995 Subordinated debt 71,646 — 69,348 — 1 See “Note 3 – Securities” for further detail of individual investment categories. The short maturity of Seacoast’s assets and liabilities results in having a significant number of financial instruments whose fair value equals or closely approximates carrying value. Such financial instruments are reported in the following balance sheet captions: cash and due from banks, interest bearing deposits with other banks, FHLB borrowings and securities sold under agreements to repurchase, maturing within 30 days. The following methods and assumptions were used to estimate the fair value of each class of financial instrument for which it is practicable to estimate that value at September 30, 2022 and December 31, 2021: Held-to-maturity debt securities : These debt securities are reported at fair value utilizing level 2 inputs. The estimated fair value of a security is determined based on market quotations when available or, if not available, by using quoted market prices for similar securities, pricing models or discounted cash flow analyses, using observable market data where available. The Company reviews the prices supplied by independent pricing services, as well as their underlying pricing methodologies, for reasonableness and to ensure such prices are aligned with traditional pricing matrices. From time to time, the Company will validate, on a sample basis, prices supplied by the independent pricing service by comparison to prices obtained from other brokers and third-party sources or derived using internal models. Loans : Fair values are estimated for portfolios of loans with similar financial characteristics. Loans are segregated by type, such as commercial or mortgage. Each loan category is further segmented into fixed and adjustable-rate interest terms as well as performing and nonperforming categories. The fair value of loans is calculated by discounting scheduled cash flows through the estimated life including prepayment considerations, using estimated market discount rates that reflect the risks inherent in the loan. The fair value approach considers market-driven variables including credit related factors and reflects an “exit price” as defined in ASC Topic 820. Deposit liabilities : The fair value of demand deposits, savings accounts and money market deposits is the amount payable at the reporting date. The fair value of fixed maturity certificates of deposit is estimated using the rates currently offered for funding of similar remaining maturities.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation: The accompanying unaudited condensed consolidated financial statements of Seacoast Banking Corporation of Florida and its subsidiaries (the “Company”) have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, they 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.
Use of Estimates	Use of Estimates: The preparation of these condensed 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 determination of the allowance for credit losses, acquisition accounting and purchased loans, intangible assets and impairment testing, other fair value measurements and contingent liabilities.
Recently Issued Accounting Standards, Not Yet Adopted	Recently Issued Accounting Standards, Not Yet Adopted In March 2022, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2022-02, Financial Instruments Credit Losses (Topic 326), Troubled Debt Restructurings and Vintage Disclosures . ASU 2022-02 eliminates the accounting guidance for troubled debt restructurings (“TDRs”) in ASC 310-40, Receivables - Troubled Debt Restructurings by Creditors , and introduces new disclosures related to modifications with borrowers that are experiencing financial difficulties. ASU 2022-02 also requires the disclosure of current-period gross write-offs by year of origination for financing receivables held at amortized cost. The amendments in ASU 2022-02 are effective for fiscal years beginning after December 15, 2022, and early adoption is permitted. The impact to the Company’s consolidated financial statements of the adoption of ASU 2022-02 is not expected to be material.
Fair Value Measurement	Held-to-maturity debt securities : These debt securities are reported at fair value utilizing level 2 inputs. The estimated fair value of a security is determined based on market quotations when available or, if not available, by using quoted market prices for similar securities, pricing models or discounted cash flow analyses, using observable market data where available. The Company reviews the prices supplied by independent pricing services, as well as their underlying pricing methodologies, for reasonableness and to ensure such prices are aligned with traditional pricing matrices. From time to time, the Company will validate, on a sample basis, prices supplied by the independent pricing service by comparison to prices obtained from other brokers and third-party sources or derived using internal models. Loans : Fair values are estimated for portfolios of loans with similar financial characteristics. Loans are segregated by type, such as commercial or mortgage. Each loan category is further segmented into fixed and adjustable-rate interest terms as well as performing and nonperforming categories. The fair value of loans is calculated by discounting scheduled cash flows through the estimated life including prepayment considerations, using estimated market discount rates that reflect the risks inherent in the loan. The fair value approach considers market-driven variables including credit related factors and reflects an “exit price” as defined in ASC Topic 820. Deposit liabilities : The fair value of demand deposits, savings accounts and money market deposits is the amount payable at the reporting date. The fair value of fixed maturity certificates of deposit is estimated using the rates currently offered for funding of similar remaining maturities.
