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 six months ended June 30, 2021 are not necessarily indicative of the results that may be expected for the year ending December 31, 2021 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, 2020. 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.

Earnings per Share	Earnings per Share Basic earnings per common share is computed by dividing net income available to common shareholders by the weighted average number of shares of common stock outstanding during the period. For the three and six months ended June 30, 2021, no options to purchase shares of the Company's common stock were anti-dilutive, compared to 508,000 and 489,000 shares that were excluded in the computation of diluted earnings per share for the three and six months ended June 30, 2020, respectively. Three Months Ended June 30, Six Months Ended June 30, (Dollars in thousands, except per share data) 2021 2020 2021 2020 Basic earnings per share Net income $ 31,410 $ 25,080 $ 65,129 $ 25,789 Average common shares outstanding 55,421 52,985 55,347 52,394 Net income per share $ 0.57 $ 0.47 $ 1.18 $ 0.49 Diluted earnings per share Net income $ 31,410 $ 25,080 $ 65,129 $ 25,789 Average common shares outstanding 55,421 52,985 55,347 52,394 Add: Dilutive effect of employee restricted stock and stock options 480 323 480 413 Average diluted shares outstanding 55,901 53,308 55,827 52,807 Net income per share $ 0.56 $ 0.47 $ 1.17 $ 0.49 Net income has not been allocated to unvested restricted stock awards that are participating securities because the amounts that would be allocated are not material to net income per share of common stock. Unvested restricted stock awards that are participating securities represent less than one percent of all of the outstanding shares of common stock for each of the periods presented.

Securities	Securities The amortized cost, gross unrealized gains and losses and fair value of securities available-for-sale and held-to-maturity at June 30, 2021 and December 31, 2020 are summarized as follows: June 30, 2021 (In thousands) Amortized Gross Gross Unrealized Fair Debt securities available-for-sale U.S. Treasury securities and obligations of U.S. government agencies $ 7,412 $ 439 $ (2) $ 7,849 Mortgage-backed securities and collateralized mortgage obligations of U.S. government-sponsored entities 987,402 14,224 (5,906) 995,720 Private mortgage-backed securities and collateralized mortgage obligations 73,469 1,938 (218) 75,189 Collateralized loan obligations 209,835 22 (165) 209,692 Obligations of state and political subdivisions 32,288 2,038 — 34,326 Totals $ 1,310,406 $ 18,661 $ (6,291) $ 1,322,776 Debt securities held-to-maturity Mortgage-backed securities and collateralized mortgage obligations of U.S. government-sponsored entities $ 493,467 $ 5,697 $ (9,875) $ 489,289 Totals $ 493,467 $ 5,697 $ (9,875) $ 489,289 December 31, 2020 (In thousands) Amortized Gross Unrealized Gross Unrealized Fair Debt securities available-for-sale U.S. Treasury securities and obligations of U.S. government agencies $ 8,250 $ 528 $ (1) $ 8,777 Mortgage-backed securities and collateralized mortgage obligations of U.S. government-sponsored entities 1,038,437 23,457 (1,240) 1,060,654 Private mortgage-backed securities and collateralized mortgage obligations 89,284 2,131 (210) 91,205 Collateralized loan obligations 202,563 279 (647) 202,195 Obligations of state and political subdivisions 33,005 2,321 — 35,326 Totals $ 1,371,539 $ 28,716 $ (2,098) $ 1,398,157 Debt securities held-to-maturity Mortgage-backed securities of U.S. government-sponsored entities $ 184,484 $ 7,818 $ (123) $ 192,179 Totals $ 184,484 $ 7,818 $ (123) $ 192,179 Proceeds from sales of securities for the three and six months ended June 30, 2021 were $56.2 million, resulting in gross gains of $0.2 million and gross losses of $0.3 million. For the three months ended June 30, 2020, proceeds from sales of securities were $64.5 million, which resulted in gross gains of $2.3 million and gross losses of $1.1 million. For the six months ended June 30, 2020, proceeds from sales of securities were $92.3 million, which resulted in gross gains of $2.4 million and gross losses of $1.3 million. Also included in “Securities gains (losses), net” is an increase of $18 thousand and a decrease of $0.1 million for the three and six months ended June 30, 2021, respectively, and increases of $0.1 million and $0.2 million for the three and six months ended June 30, 2020, respectively, in the value of a CRA-qualified mutual fund. 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 June 30, 2021, debt securities with a fair value of $388.1 million were pledged primarily as collateral for public deposits and secured borrowings. The amortized cost and fair value of debt securities held-to-maturity and available-for-sale at June 30, 2021, 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.

The tables below indicate the fair value of available-for-sale debt securities with unrealized losses for which no allowance for credit losses has been recorded.

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 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 June 30, 2021, no allowance for credit losses has been recorded. At June 30, 2021, the Company had $0.2 million of unrealized losses on private label residential and commercial mortgage-backed securities and collateralized mortgage obligations having a fair value of $16.7 million. The collateral underlying these mortgage investments is primarily residential real estate. The securities have average credit support of 35%. 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 June 30, 2021, no allowance for credit losses has been recorded. At June 30, 2021, the Company had $0.2 million in unrealized losses in uncapped 3-month LIBOR floating rate collateralized loan obligations ("CLOs") having a fair value of $91.6 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 June 30, 2021, these positions are in AAA and AA tranches, with average credit support of 34% and 23%, 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 June 30, 2021, no allowance for credit losses has been recorded. All 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 June 30, 2021, no allowance for credit losses has been recorded. Included in other assets at June 30, 2021 is $31.2 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 that may have a significant adverse effect on the fair value of these cost method investment securities. Also included in other assets is a $6.4 million investment in a CRA-qualified mutual fund carried at fair value. Accrued interest receivable on AFS and HTM debt securities of $2.6 million and $0.8 million at June 30, 2021, respectively, and $3.2 million and $0.4 million at December 31, 2020, respectively, is also included in other assets.

Receivables [Abstract]
Loans	Loans Loans 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 may be from the occupant of the residential property or from cash flows on rental income from the successful operation of the 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 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.

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.

Loans Modified in Connection with COVID-19 Pandemic The CARES Act, which was signed into law on March 27, 2020, and amended by the Consolidated Appropriations Act on December 27, 2020, encourages financial institutions to practice prudent efforts to work with borrowers financially impacted by the COVID-19 pandemic by providing an option to exclude from TDR consideration certain loan modifications that might otherwise be categorized as TDRs under ASC 310-40. This option is available for modifications that are deemed to be COVID-related, where the borrower was not more than 30 days past due on December 31, 2019, and the modification is executed between March 1, 2020 and the earlier of (i) January 1, 2022 or (ii) 60 days after the end of the COVID-19 national emergency. Federal banking regulators issued similar guidance that also allows lenders to conclude that short-term modifications for borrowers affected by the pandemic should not be considered TDRs if the borrower was current at the time of modification. Seacoast has provided financially impacted borrowers with loan accommodations, primarily consisting of payment deferrals of up to six months. At its peak on June 30, 2020, loans on deferral represented $1.1 billion, or 21%, of total non-PPP loans. In the second half of 2020, the large majority of these borrowers successfully resumed making contractual payments, and the level of loans with accommodations has decreased to $6.8 million, or 0.1%, of total non-PPP loans as of June 30, 2021. Types of outstanding accommodations at June 30, 2021 included a combination of one or more of the following: full payment deferral, partial payment deferral, reduction of interest rate, extension of the original maturity date, or re-amortization of the facility. The following table presents the balance of loans with active payment accommodations at the specified dates, excluding PPP loans: (In thousands) June 30, 2021 December 31, 2020 Construction and land development $ — $ 1,032 Commercial real estate - owner-occupied 1,612 14,248 Commercial real estate - non owner-occupied 2,257 32,549 Residential real estate 1,702 12,839 Commercial and financial 811 11,915 Consumer 399 1,479 Totals $ 6,781 $ 74,062 Troubled Debt Restructured Loans The Company’s TDR concessions granted to certain borrowers generally do not include forgiveness of principal balances, but may include interest rate reductions, an extension of the amortization period and/or converting the loan to interest only for a limited period of time. Loan modifications are not reported in calendar years after modification if the loans were modified at an interest rate equal to the yields of new loan originations with comparable risk and the loans are performing based on the terms of the restructuring agreements.

During the six months ended June 30, 2021, there were two defaults totaling $0.1 million of loans that had been modified in TDRs within the preceding twelve months. During the six months ended June 30, 2020, there were three defaults totaling $1.4 million of loans to a single borrower 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, $6,000 and $21,000 for the three months ended June 30, 2021, and 2020, respectively, and $11,000 and $46,000 for the six months ended June 30, 2021, and 2020, respectively, was included in interest income and represents the change in present value attributable to the passage of time.

Forecast data is sourced primarily from Moody’s Analytics, a firm widely recognized for its research, analysis, and economic forecasts. For portfolio segments with a weighted average life longer than three years, the Company reverts to longer-term historical loss experience to estimate losses over the remaining life of the loans within each segment. Historical credit losses provide the basis for the estimation of expected credit losses. Adjustments to historical loss information are made for differences in current loan-specific risk characteristics such as differences in underwriting standards, portfolio mix, delinquency level, loan to value ratios, borrower credit characteristics, loan seasoning or term as well as for changes in current and forecasted environmental conditions, such as changes in unemployment rates, property values, occupancy rates, and other macroeconomic metrics. As of June 30, 2021, the Company utilized Moody’s most recent “U.S. Macroeconomic Outlook Baseline” scenario and considered the uncertainty associated with the assumptions in the Baseline scenario, including the potential for increasing COVID-19 infections, including from variants, and the resulting potential erosion in consumer confidence, and the risk that government stimulus programs are less effective than expected. Outcomes in any or all of these factors could differ from the Baseline scenario, 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. In the Construction and Land Development segment, the decrease in reserves during the quarter reflects improved economic variables relating to residential real estate. In this segment, the primary source of repayment is typically from proceeds of the sale, refinancing, or permanent financing of the underlying property; therefore, industry and 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 reserves is primarily the result of improved economic variables relating to unemployment. Risk characteristics include but are not limited to, collateral type, loan seasoning, and lien position. In the Commercial Real Estate - Non Owner-Occupied segment, the decrease in reserves reflects lower loan balances and improved economic forecast variables including lower unemployment. Repayment is often dependent upon rental income from the successful operation of the underlying property. Loan performance may be adversely affected by general economic conditions or conditions specific to the real estate market, including property types. Collateral type, loan seasoning, and lien position 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 decrease in reserves reflects lower loan balances and improved economic forecast variables including lower unemployment. Risk characteristics considered for this segment include, but are not limited to, collateral type, lien position, loan to value ratios, 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 primarily attributed to improvement in economic forecast variables including unemployment, partially offset by higher loan balances. 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 to value ratios, loan seasoning and FICO score. Nominal changes in the reserve during the quarter reflect changes in underlying economic variables.

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 June 30, 2021, the interest rate swaps had an aggregate notional value of $182.1 million, with a fair value of $9.5 million recorded in other assets and other liabilities. As of December 31, 2020, the interest rate swaps had an aggregate notional value of $182.4 million, with a fair value of $13.3 million recorded in other assets and other liabilities. The weighted average maturity was 7.2 years at June 30, 2021 and 7.5 years at December 31, 2020. 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 six months ended June 30, 2021, the Company recognized a loss through other comprehensive income of $0.1 million and $0.3 million, respectively, and reclassified $57 thousand and $100 thousand, respectively, out of accumulated other comprehensive income and into interest income. As of June 30, 2021 and December 31, 2020, the interest rate floors had a fair value of $0.7 million and $1.0 million, respectively, recorded in other assets in the consolidated balance sheet. Over the next twelve months the Company expects to reclassify $0.3 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 June 30, 2021 and December 31, 2020. The aggregate fair value and contractual balance of loans held for sale as of June 30, 2021 and December 31, 2020 is as follows: (In thousands) June 30, 2021 December 31, 2020 Aggregate fair value $ 42,793 $ 68,890 Contractual balance 41,629 66,415 Excess 1,164 2,475 Loans : Loans carried 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 June 30, 2021 capitalization rates utilized to determine fair value of the underlying collateral averaged approximately 7.2%. 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 $14.3 million with a specific reserve of $4.1 million at June 30, 2021, compared to $16.5 million with a specific reserve of $7.7 million at December 31, 2020. For loans classified as Level 3, changes included loan additions of $3.7 million offset by $1.5 million in paydowns and charge-offs for the six months ended June 30, 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. For OREO classified as Level 3 at June 30, 2021, changes during the six months ended included additions of $1.3 million offset by sales and writedowns of $1.6 million. 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. There were no such transfers during the six months ended June 30, 2021 and 2020. 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 June 30, 2021 and December 31, 2020 is as follows: (In thousands) Carrying Amount Quoted Prices in Active Markets for Identical Assets Significant Other Observable Inputs Significant Unobservable Inputs June 30, 2021 Financial Assets Debt securities held-to-maturity 1 $ 493,467 $ — $ 489,289 $ — Time deposits with other banks 750 — 759 — Loans, net 5,345,710 — — 5,367,748 Financial Liabilities Deposit liabilities 7,836,436 — — 7,838,507 Subordinated debt 71,506 — 58,342 — December 31, 2020 Financial Assets Debt securities held-to-maturity 1 $ 184,484 $ — $ 192,179 $ — Time deposits with other banks 750 — 762 — Loans, net 5,633,810 — — 5,686,019 Financial Liabilities Deposit liabilities 6,932,561 — — 6,936,097 Subordinated debt 71,365 — 58,227 — 1 See “Note D – 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 June 30, 2021 and December 31, 2020: 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.

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.

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.
